GEO-RESOURCES SECTOR 1. MINERAL PROGRAMME

1.1. Summary Although the regulation of government of minerals and coal mines, as the

implementation of Law No. 4 Year 2009 which regulates the issuance of new mining permit has not been completed, ming activities continue apace with existing permits. This may occur either because the price of some commodities tend to remain stable or increase, or because of government policies that are in transition. Gold and iron ore are commodites whose prices have tended to increase, while nickel is relatively stable.

Resources and reserves of metallic mineral continue to change in response to exploration and production activities of existing companies. Grasberg, Batuhijau, Gosowong, Pongkor are still the largest contributors of resources, reserves and production of gold and or copper in Indonesia. Soroako, Pomalaa, Weda Bay, P. Gag and Tanjung Buli are the largest contributors of resources and reserves of nickel. Some locations of existing exploration companies are still allowed to add metallic mineral resources and reserves such as Tumpangpitu, Miwah, Sihayo, Papandayan and Lakuwahi (gold), Tayan (bauxite), Dairi (lead and zinc).

Total resources and reserves of some metallic mineral Indonesia until 2009

is described in table below.

1.2. Annual Review of Individual Technical Activities

During the period mid-late 2009 until mid-early 2010, the Geological Agency as the government institution in charge of doing an inventory and exploration of mineral resources and the provision of preliminary data have been conducting investigations in some selected areas with different types of mineral commodities such as minerals that have a content of lead, molybdenum, gold, nickel, tin and iron.

Exploration activities for galena in Pasaman, West Sumatera foundnd a potential source of galena with inferred resources based on geophysical interpretation of 288 634 320 tons with an average content of Pb 2.5693%.

Indication of mineralization encountered in the Waemese area, South Buru, Maluku

based on the results of chemical analysis of rock samples showed six grams of gold / ton, As 2.6 gr / ton and 5.7 g Hg / tonne. This sampled rock outcrop was sampled in a broad zone and based on the results of chemical analysis, supported by mineragraphic analysis, temporarily is estimated as a prospect to be researched further.

Rare metal was found in soils in the area of Sosortolong South Tapanuli, North

Sumatera, was estimated as the result of weathering of granitic rocks to have an average thickness of 1.6 m. This was localized from interpretation of soil geochemical distribution of rare metal elements with the threshold value for Ce> 1.7%.

In the area of North Luwu, South Sulawesi, two types of deposit estimated to develop in this area are metasomatic contact and placer deposits. Alluvial gold deposits were found at Dodolo and Tedeboek with hypothetical resources 0.107313 tons with a gold content of 50 mg/m3.

Based on the ore-forming zone, the metallic mineralization in Lebak district, Banten is divided into two zones of mineralization represented by the bottom zone at Ciujung and Cihinit area dominated by base metals with a mineralogical association consisting of sphalerite, chalcopyrite, galena, and pyrite and the upper zone of mineralization at G. Julang dominated by precious metals with associated minerals gold and pyrite. Results of chemical analysis of the lower zone at Cihinit indicates Pb content reaches 18.26% and 4.6% Zn and at Ciujung area 11.98% Pb and 3.11% Zn respectively. While the upper zone has a relatively high content of Au ranged from 8.5 ~ 39 g / t Au, and 6 ~ 66 g / t. Ag in association with propilitic alteration, argillic alteration and silicification. Economically, the content of gold in this region (G. Julang) has a potential resource estimated as 250,000 tons of ore.

In the border region of Nunukan Regency, gold mineralization was found at Seruyung. Here the type of alteration and distribution pattern indicate high-sulphidation type with a assemblage of alteration minerals comprising a silica core covered by advanced argillic alteration consisting of the silica-pyrite-allunite grades to intermediate argillic broader form of kaolinite.

The result of the investigation in Nabire Regency, Papua encountered a laterite nickel deposit in ultramafic rock units and secondary gold deposits in alluvium.

As the result of the investigation in Gayo Lues, Aceh, molybdenum (Mo) was found in Alur Putih with a total ore resources estimated as 5.585 tons, and galena in the Pepelah area with 9.24 tons of resources.

In the area of Manokwari regency, Papua, tin and gold of greisen type was found in the area of S. Moni (Duibay Village, Menyambou District). Gold of metasomatic type mineralization is estimated to be prospective in the northern region where the indications are known from the results of panning.

Metallic minerals prospects in Polewali Mandar Regency, South Sulawesi, are in the form of gold, iron, and galena.

Mineral exploration cooperation with KIGAM entitled the Development of GIS for Mineral Potential Mapping in Eastern Indonesia is still in progress towards its third year. GIS training was held on 10 – 12 May 2010 in Bandung by Dr. Saro Lee, and field investigation will be carried out on August 2010 in Flores Island.

D. Carbon Capture and storage (CCS) Study and Activity in Indonesia

In Indonesia, CCS is possible to be undertaken into several environments or ways in

terms of Geological storage, such as Oil and Gas Reservoirs, Coal Bed Methane Reservoirs and Saline Water. The CCS-EOR seems to be one of the viable options in financing demonstration projects, together with government support to render a CCS trust fund.

In order to assess the CCS and its potential combined with Enhanced Oil Recovery (EOR) in Indonesia, LEMIGAS has conducted preliminary global storage estimates in Indonesia. A recent study shows that East Kalimantan and South Sumatra region can be selected as potential candidates for CCS projects as many depleted oil/gas reservoirs are close to the CO2 sources of oil and gas industry and coal power plan activities. Another potential of CCS project is in Natuna area in which a giant gas reserves with 70% of CO2 can be used as CO2 source and then stored into saline aquifer or depleted oil/gas reservoirs.

Figure below indicates the Potential Area for CCS System Application in Indonesia.

Page 13: CBM Program Indonesia_CR2010

CCOP Member Country Report: INDONESIA 11

These recommended areas are based on the initial assessment of the prospect of CO2 storage in Indonesia’s geological formations, includes good reservoir characterisation and geologically stable as well as existing infrastructure and low population density. It is estimated that a CO2 volume of 38-152 million tonnes may be possible to be stored in the depleted oil reservoirs in East Kalimantan region, and potential oil recoveries of 265-531 million barrels could be obtained. In South Sumatera region, a CO2 volume of 18-36 million tonnes may be possible to be stored in the depleted oil and gas reservoirs with potential oil recoveries of 84-167 million barrels.

Another possibility CO2 Storage is in unminable Coal, i.e. post production of CBM reservoir can be also considered. Coal basins are found in Indonesia and further CCS deployment can be introduced to enhance CBM recovery in the South Sumatera region that contains abundantly Coal Bed Methane (CBM) resources. The Figure below shows the Coal Basins in Indonesia.

To implement CCS, since April 2009 Indonesia became a founding member of Global

CCS Initiatives (GCCSI) led by Australia.

The event in conjunction with CCS activity is that there resulted in a launching Indonesia CCS Study by the CCS Working Group & Joint workshop “CARBON CAPTURE AND STORAGE IN INDONESIA” been held in Jakarta, on 10 -12 November 2009.

Page 14: CBM Program Indonesia_CR2010

12 CCOP Member Country Report: INDONESIA

The first Indonesia CCS Study, entitled “Understanding CCS Potential in Indonesia” conducted by CCS Working Group has been presented. The study provided fundamental principles and preliminary understanding of CCS potential in Indonesia that extend from capture technology, transportation methods, subsurface geological storage and other key elements.

The working group is comprised of the Ministry of Energy and Mineral Resources, Ministry of Environment, Indonesian State Electricity Corporation, Shell, Indonesian National Committee-World Energy Council and supported by the British Embassy in Jakarta.

On the same occasion, the Ministry of Energy and Mineral Resources (MEMR) and its Agency of Research and Development for Energy and Mineral Resources (ARDMER), jointly with the International Energy Agency (IEA) and the Asia Pacific Economic Cooperation (APEC) Expert Group on Clean Fossil Energy (EGCFE) held a Joint Workshop “Carbon Capture and Storage in Indonesia”.

The workshop is a part of series of bilateral projects that currently underway among IEA, MEMR and LEMIGAS to assist the Indonesian Government to increase capacity building and identify ways to quicken the uptake of CCS key elements. A similar goal is also owned by the APEC Expert Group on Clean Fossil Energy which aims at exploring the potential of CCS in the APEC region, raising knowledge and awareness of CCS among developing APEC member economies.

The workshop recommendation agreed that the commercial deployment of CCS should be accelerated in Indonesia. Though significant challenges may occur if CCS is to be successfully commercialized, i.e. the lack of appropriate long–term policy frameworks and significant financial incentives to justify investment on early demonstration projects. The next action is still needed by Indonesia such as: Detailed study of CCS; Capacity building (Technological Transfer); International Funding Pilot Project; and Public support.

A Proposed Detailed CCS Study for action plan in Indonesia: (1) Geological Potential

Storage and Site Characterisation and Selection for both EOR and non–EOR, (2) Laboratory Research on CO2 Storage in unminable coal seam (CBM reservoir) in Indonesia.

2.2.2. Geothermal

Indonesia is a country that has abundant geothermal resources. They are mainly distributed along the Indonesian Volcanic Belts, however some are also associated with non volcanic environments (intrusive, tectonic). By December 2009, there were 265 geothermal locations on inventory with the total energy potential of about 28.528 MWe. These include 8935 MWe of Speculative Resources, 4551 MWe of Hypothetical Resources, 11704 MWe of Possible Reserves, 1050 MWe Probable Reserves and 2288 Mwe of Proven Reserves. From this, twenty six new working areas (WKP) have been issued by the Government, 7 WKP finished tendering, 14 in bidding process, and 5 ready to bid. These areas include Jaboi (NAD), Seulawah Agam (NAD), Gunung Talang (West Sumatera), Bukit Kili (West Sumatera), Liki-Pinangawan-Muaralabuh (West Sumatera), Sipaholon-Ria (North Sumatera), Sorik Marapi-Roburan-Sampuraga (North Sumatera), Rantau Dadap (South Sumatera), Rajabasa (Lampung), Suoh Sekincou (Lampung), Tampomas (West Java), Cisolok Cisukarame (West Java), Tangkuban Parahu (West Java), Ungaran (Central Java), Ngebel Wilis (East Java), Blawan Ijen (East Java), Kaldera Danau (Banten), Guci (Central Java), Baturaden (Central Java), Hu’u Daha (West Nusa Tenggara), Sokoria (East Nusa Tenggara),

CCOP Member Country Report: INDONESIA 13

Atadei (East Nusa Tenggara), Jailolo (North Maluku), Songa Wayaua (North Maluku), Marana (Central Sulawesi), and Suwawa (Gorontalo).

Indonesia has a set of long term policies for development of geothermal energy, as embodied in the Geothermal Development Road Map of 2004-2025. Indonesia envisions that by 2025, about five percent of our national energy needs, will be met through the use of geothermal energy. So far, Indonesia only used 1189 MWe of 7 locations of the available resources. This total installed capacity is less than 3 % from the total locations. These include 375 MWe in G. Salak, 200 MWe in Kamojang, 255 MWe in Darajat, 227 MWe in Wayang Windu, 60 MWe in Dieng, 60 MWe in Lahendong , and 12 MWe in Sibayak.

The geothermal locations are mainly still in the stage of inventory survey (142 locations or 53,58%). To increase the status of survey and to accelerate geothermal development, in 2010 the Geological Agency conducts preliminary survey, detailed surveys, heat flow survey, and core hole temperature survey. Preliminary Survey is conducted at 4 locations: Tali Abu (Kepulauan Sula, Maluku), Pasaman Barat (West Sumatra), Kandangan (South Kalimantan), and Sanggau and Kapuas Hulu (West Kalimantan). Detailed Survey is conducted at 8 locations: Bora (Donggala, Central Sulawesi), Lili (Polewali Mandar, West Sulawesi), Tehoru (Maluku), Kapahiang (Bengkulu), Telomoyo (Central Java), Lainea (Kendari, South East Sulawesi), Gunung Kapur (Kerinci, Jambi), and Arjuno Welirang (East Java). Heat Flow Survey is conducted at 1 location: Limbong, South Sulawesi. Core hole temperature survey is conducted at 1 location: Gunung Lawu (East Java and Central Java). Beside the survey activities, we evaluate the geothermal prospect areas (Danau Ranau-Lampung, Bonjol-West Sumatera, Gunung Endut-Banten, Lompio-Tambu- Central Sulawesi, and Lesugolo-Eat Nusa Tenggara) and examine the characteristic of non-volcanic geothermal resources in Central Sulawesi.

The Geological Agency participated in the World Geothermal Congress 2010 in Bali from 25-30 April 2010. The Congress which had the theme: ‘Geothermal: the Energy to Change the World’, was held for exchange of ideas and sharing experiences not only on technical and financing aspects but also on the policy and global politics of the energy sector. The Geological Agency also had joined cooperation during the fiscal year 2010 with the Japanese goverment (JICA) in a master plan study of geothermal development in Indonesia.

Base on investigation by preliminary and detailed survey, geothermal prospects are mostly concentrated in Sumatera (86 locations), Jawa (71 locations), Sulawesi (55 locations), and the rest are distributed in other islands.

A larger part of geothermal areas in Indonesia (54,34%) are still in the stage of preliminary survey. These areas need to increase status of survey by government, company or collaboration with other countries. Particularly for those are of small scale and situated in remote islands, the government has to be more involved in developing this kind of resource.

There were 266 geothermal areas up to June 2010 having 28,950 MW potential resources. 204 locations (77%) associated with volcanic and 62 (23%) associated with non volcanic. However, only 1189 MWe, about 52 % of proven reserve or + 4 % of the total potential resources be utilized for power plant. The geothermal utilized for power plan are located at G. Salak (375 MWe), Kamojang (200 MWe), Darajat (255 MWe), Wayang Windu (227 MWe), Dieng (60 MWe), Lahendong (60 MWe) and Sibayak (12 MWe).

In 2009-2010, the Geological Agency conducted several activities in updating and adding energy resources data and information, particularly coal, peat, oilshale. These activities were conducted in West Papua, South East Sulawesi and Central Kalimantan.

Coal inventory in Ayawasi, South Sorong Regency, West Papua Laboratory analysis result indicated total moisture value between 44.38 – 46.72 %,

volatile matter value 38.63 – 39.60 %, and calorie values between 5,282 – 5,482 cal/gr which is classified as low – medium rank. The coal resource at the investigated area is 162,583 tons and is classified as a hypothetical resource.

Coal inventory in Ransiki, Manokwari Regency, West Papua (Figure 9). Laboratory analysis results indicated moisture values between 3.43 – 5.13 %, volatile

matter value 39.99 – 48.83 %, ash value 0.49 – 17.44 %, sulphur value 0.99 – 2.85 %, FSI 1.5 - 7 and calorie value between 6,403 – 7,635 cal/gr which is classified as very high rank. Coal resources at the investigation area are 4,029,400 tons, classified as hyphothetical resources.

Oil shale inventory in Buton, Buton Regency, South East Sulawesi Province Hypothetic resources of oil shale Buton amount to approximately 9,256,856.1 tons.

Retort analyses showed average oil content, 104 l/ton, with oil shale resources containing approximately 6,050,000 barrel oil.

Peat inventory and exploration in Pangkoh, Pulang Pisau Regency, Central

Kalimantan Province (Figure 9). As the result of 30 drill-holes in the investigation area, peat thickness of 0.30 m to

6.50 m was delineated with organic main compound and water. Its organic element formed molecule chain of humate acid, fulvat, humin, carbohydrate, wax, protein, lignite, cellulose, bitumen, and other related compounds. Peat resources estimated on multiplying a vast area of peat distribution against average thickness between two isopachs is: inferred resources 908.01 million M3 or resources of 908.1 x 106x 120 kg = 108.961 x 106 kg or 108,96 million tons, dry peat (± 5% water, average bulk density of laboratory result is 120 kg/m3).

GEO-ENVIRONMENT SECTOR 4. COASTAL ZONE PROGRAMME

4.1 Summary Indonesia is the largest coastal country in the world, having a marine territory of about

2/3 of the whole Indonesian territorial area, with a total number of 17,504 islands and a total length of coastline of 94,623 km. Shorelines in Indonesia generally characterized by cliff and rock comprises almost 60% of the total length. The others are characterized by reef, sand and muddy shorelines. The totals muddy shoreline in Indonesia is at least 5% of the total length, found in the eastern coast of Sumatera (at least 1500 km), in the northern coast of Java (at least 350 km), eastern and southern coast of Kalimantan (at least 1500 km) and southern coast of Irian Jaya/Papua (at least 1400 km).

During the fiscal year 2009 and 2010, the Marine Geological Research and

Development Center, Energy and Mineral Resources Research and Development Agency, have conducted coastal geological surveys of the Cipunegara Delta, Pamanukan, West Java, Northertn coast Java.

4.2 Annual Review of Individual Technical Activities

Coastal Geological Survey of Cipunegara Delta, Pamanukan.

Geologically, the northern coast of Java which is extends eastward from Sunda Strait

to Surabaya, is a part of the extensive coastal lowland belt mainly built up from unconsolidated clay and sand. This material is derived from fluviatile (flood plain and channel deposits) and marine sediments (beach and beach ridge; mangrove swamp; near shore; and shallow marine deposits deposits), which have been deposited since 6000 years ago with some beach ridges widening to a deltaic plain.

The problematic and interesting phenomena in this area mainly comes from the

geological aspects and human pressure on the environment. The coastal environments under study here are on the both land and the marine side. Rapid development along the northern coast of Java is currently in need of coastal zone management plans as the fastest growing of the city coastal areas in the northern coast of the island require land resources. Land requirements will be increasing in the future, and an integrated study of coastal zone and marine geohazards should be undertaken.

Recently a case study in the Cipunegara Delta and its surroundings has been

undertaken in relation to its environments and ther geological hazards. The Cipunegara has a catchment of about 1,450 square kilometres, with mountainous headwater regions, carrying relics of a natural deciduous rain forest and extensive tea plantations; a hilly central catchments with teak forest, rubber plantations, and cultivated land; and a broad coastal plain bearing irrigated ricefields. The river meanders across this plain, branching near Tegallurung, where the main stream runs northwards and a major distributary, the Pancer, flows to the north-east. Aerial photographs taken in 1946, shows that subsequent further advance on the Pancer delta, and continued smoothing of the former delta lobe to the west has taken place. It confirmed this sequence with reference to the pattern of beach ridges truncated on the eastern shores of Ciasem Bay and the 1976 Landsat pictures show that a new delta has been built out to the north-east. This delta formed after the new northeast channel was built in 1960 to avoid

Page 27: CBM Program Indonesia_CR2010

CCOP Member Country Report: INDONESIA 25

flooding in the region by the river. Along the coast of Cipunegara delta, the mangrove fringe (mainly Rhizophora) has persisted on advancing sectors but elsewhere has been eroded or displaced by the construction of fishponds. There has been widespread removal of mangroves, in the course of constructing tambak (brackishwater fishponds) in this area starting 1990s, and with lack of sedimentation in places these are being eroded such as shown along the coast of Pondok Bali to the Muara Pancer Wetan. The other factor which is an influence on this area is the subsidence as shown in the seismic reflection profile and sea level fluctuation with ranges between 9-15 mm/year (based on tide analysis and altimetry satellite data/TOPEX/Poseidon and JAS-1). Earth.google 2009’s image shows that the newly build northeast delta has advanced more to the Java Sea and developed 5400 m since 1960 from the Dutch coas of 1942, indicating at least 108 m/year advance.

In order to reconstruct an updated shoreline migration history at annual scale in the Cipunegara delta and its surroundings, we have recently compiled and calculated the available data which shows that it is a dynamic area where the shoreline accretion and abrasion can be found in some places. This is due to the changing of river channels and lack of sediment distributed to the sea.

Coastal characteristics of the study area can be divided into two types such as sandy beach and muddy beach. The sandy beach type can be found in the eastern part of the study area and in Pondok Bali. This is a typically an erosion shoreline with mud deposit of flood plain found in some places. The muddy beach type can be found along the Cipunegara delta where good mangrove growth acts as an accretion shoreline. The sea bottom sediments distribution in this area is also divided into two types such as muddy sediment which can be found almost in the whole of map area and sandy mud found only in some places. The bathymetric data shows that the sea bottom morphology is relatively low angle close to the river mouth of Cipunegara with some places nearly flat with the depth ranges between 2.5 m to 20 m.

6. ENVIRONMENTAL GEOLOGY PROGRAMME

6.1. Summary

During the period of July 2009 to July 2010, the environmental geology activities covered environmental geological study for landuse planning and regional development, also environmental geology in some mining areas. The geological study for landuse planning and regional development was done in the autonomy regions or provinces where they have a high priority in development or the area that is indicated as having a high risk in change of geological environment. Environmental geology surveys in mining areas were done in areas where the presence of illegal mining and unreclaimed abandoned mines and quarries pose potential environmental problems. Another activity related to the environmental geology programme is the dissemination of environmental geological information to the provincial and regency governments.

6.2. Annual Review of Individual Technical Activities

• The environmental geological studies for landuse planning and regional development

activities were done in the autonomous regions or provinces where they have high priority in their development or the regions where a high risk in environmental damage is indicated. They include the areas in which there is landuse development and spatial planning undertaken without consideration of geological phenomena. The activities resulted in environmental geological maps, quaternary geological maps, neotectonic maps and reports of geology. In this fiscal year, this activity has been carried out in the provinces of Central Java, East Java, Bali, South Sulawesi, Southeast Sulawesi, Jambi, and Aceh.

• Environmental geology surveys in the mining areas were undertaken in North Sumatra, West Sulawesi, Southeast Sulawesi, Jambi, and West Nusatenggara. This activity results in some recommendations for spatial and landuse planning of abandoned mines and reclamation and rehabilitation of pits and quarries.

GEO-INFORMATION SECTOR 7. GEO-DATA AND INFORMATION MANAGEMENT PROGRAMME

7.1. Summary

Under the Geodata and Information Sector, the following activities were carried out during the review period:

a) participation in the Geological Museum book project b) development of geological information metadata c) Updating of geological maps using satellite imagery technique

7.2. Annual Review of Individual Technical Activities

7.2.1. Geological Museum Book Project

The CCOP book entitled “Geological Museums of East and Southeast Asia” is aimed to be published as a companion to the previously published “Geoheritage of East and Southeast Asia” book (published in November 2008). Both of the books ares attributed as a contribution of CCOP to the International Years of Planet Earth (IYPE) global environmental campaign to save the earth from worsening environmental degradation. The publication CCOP Geological Museums in East and Southeast Asia was polanned to be published for the 56th Steering Committee Meeting at Busan Korea, but due to certain circumstances, it has been rescheduled to be launched on the 57th CCOP Annual and 56th Steering Committee Meeting in October 2010 in Manado, Indonesia.

Concurrent with rapid development of geosciences and increasing public demand on

geological information to be used for many purposes, the Ministry of Energy and Mineral Resources (MEMR) has developed some geological museums in several areas with specific and important geological heritage sites. These newly built thematic geological museums will complete the networking of existing Geological Museum of Indonesia in Bandung. The philosophical background to the decision to develop geological museums is an understanding that such museums will play an important role as an effective educational facility for the dissemination of geological information related to natural resources, environment and hazards.

Nowadays, there are eight museums that can be regarded as geological museum in

Indonesia, as follows: 1. Geological Museum of Indonesia in Bandung West Java 2. Ketep Volcano Museum in Magelang, Central Java 3. Batur Volcano Museum in Bangli, Bali 4. Merapi Volcano Museum in Sleman, Yogyakarta 5. Karst Museum in Wonogiri 6. Aceh Tsunami Museum, Banda Aceh, Nangroe Aceh Darusalam 7. Gawitra Oil and Gas Museum, Jakarta 8. Sangiran Geoarcheological Museum, Sragen, Central Java

The manuscript consisting of the description of these geological museums completed with related illustrations and maps has been edited by the assigned editors of the CCOP Technical Secretariat.

Official Meeting on Minerals (ASOMM X) in Bangkok, Thailand, on 1 to 5 March 2010, where the CCOP-TS presented some of the CCOP database application that could be also used by ASEAN member countries.

A small meeting with the delegation from AIST, Japan; DR. Koji Wakita and DR.

Tetsuji Ohno was held on 1 to 2 July 2010. The meeting discussed the willingness of AIST, Japan for enhancing the ASEAN Mineral Database Applications. The meeting agreed that Japan Could provide soft ware such as:

• Thesaurus; this software could be used to translate other letters or characters into the

Latin alphabet. • Supporting application for data transfer process from ASEAN member database to

the existing ASEAN Mineral Database application. • Providing basic map for GIS of ASEAN Mineral Distribution map.

To accelerate the development of ASEAN mineral Data collecting, Japan will carry

out socialization to ASEAN member Countries on the event of the Workshop on ASEAN Database Mineral Trade in Manado in October 2010. This Workshop will be parallel with the 47th CCOP Annual Session and 56th Steering Committee Meeting of the CCOP.

• Creating a data structure entry for Mineral Trade, Supply and Demand to be

incorporated in the ASEAN Mineral Database and Information System. • An "ASEAN Training and Workshop on Mineral Database Management" for 4 (four)

ASEAN member countries (Cambodia, Lao PDR, Myanmar and Vietnam) was conducted, with the participation of 8 delegates, on 12 to 23 July 2010, in Bandung. Several matters discussed were :

• The need to develop a thesaurus and translation facilities from some languages / letters into English / Latin alphabet.

• The need to develop data transfer applications with a uniform data format for ease of charging data.

• The country where the internet connection is not as fast as others can send data via email to Indonesia and then Indonesian will import the data into the application for further verification of each country via the internet.

• Each ASEAN country should sign the agreement about the person who will be responsible for filling out the data into the application (the person in charge on the ASEAN database).

• The need to develop a small application to convert the UTM coordinates system into the decimal degrees system.

• The delegates proposed a distributed server application to be placed in their respective countries which can be accessed locally.

• Conducting Workshop on National Geological Resources Data Management in Bali on 27 to 30 July 30, 2010, by inviting 23 local government of Mines and Energy in Indonesia except the Sumatra region.

• Development of database applications and sub database ASEAN which include mineral resources, import export trade, minerals and environmental legislation, company directory, research & development business directory, supply & demand data for the implementation of ASEAN Trade Mineral Database Workshop that is

scheduled to take place simultaneously with the activities of CCOP on October 2010 in Manado, Indonesia.

7.2.3. Seminar/Workshops, Mapping and Research, and Satellite Imagery

Interpretation Seminars/Workshops The Geological Agency have conducted several seminar/workshops related to oil and gas exploration and Geological Hazard Mitigation as follow: 1. South Sumatra Sedimentary Basin Assessment in cooperation with BP Migas (

Palembang, South Sumatera September 2009), 2. Oil and gas potential in Northern East Java Sedimentary Basin in cooperation with BP.

Migas (Surabaya, East Java, June 2010). 3. Seminar for Geological hazard mitigation in Padang (West Sumatra), Medan (North

Sumatra), Banda Aceh (NAD) and Mataram (West Nusa Tenggara). Geological mapping and Research 1. Geological mapping scale 1:50.000 in Southern Mountain Central Java. 2. Quaternary research and mapping in Northern Java Coastal Plain (Cirebon, West Java;

Pekalongan, Pemalang and Semarang, Central Java). 3. Basin sedimentation, oil and gas related research in the South Sumatra Basin,

Ketungau West Kalimantan Basin, Sengkang South Sulawesi Basin, Tanimbar Basin, Maluku.

Analyses of satellite imagery for geological map updating and database

Integrated IFSAR, SRTM, LANDSAT ETM 7, ASTER satellite imagery interpretation in Sulawesi, Maluku and Nusa Tenggara for geological map updating from 1:250.000 to 1:50.000 scale. Combination between IFSAR and SRTM data is useful to determine morphology and geological structure. These data are integrated with active satellite data acquisition (LANDSAT and ASTER) to be able to analyze lithological aspects. The geological map produced using satellite imagery analyses is controlled by secondary data research, conventional mapping and field checking. Using the above techniques, updating of the 1:250.000 geological map to more detail geological map at scale 1:50.000 can be done accurately. It is targeted to have 740 sheets completed for Sulawesi, Maluku, Bali and West Nusa Tenggara in 2010.
