Welcome Remarks

Praise and gratitude to God Almighty for His grace and gift to all of us, and with His permission so that international conference with the theme “Strengthening Collaboration of Science, Technology, and Humanities towards Sustainable

Development” can be carried out well and this Guidebook can be published. The theme was chosen with the reason to give attention to the academic world about the importance of increasing the quantity and quality of research and community service for our nation’s civilization, so that this increase can bring Indonesia to become a nation that has high civilization. National academics have produced a lot of research on the strengthening and development of science and technology in research activities and community service, but there are still many that have not been widely disseminated and published, so it is not accessible to the wider community who need it. On this basis, this international conference became one of the venues for national academics to present their research, as well as exchange information and deepen research issues, and develop sustainable cooperation. Theconferencewasattendedbyresearchersfromvariousfieldsofsciencefromallover Indonesia,whohaddiscussedvariousfieldsofstudy in thefieldsofscience,technology and humanities in order to provide ideas and solutions to strengthen Indonesia’s role in building the nation’s civilization. Finally, we would like to thank the leaders of the University, Speakers, Participants, Organizers, and Sponsors who have tried to make this conference a success.

INTRODUCTION

In everyday life The human can not be

detached from the use of plastic materials.

Most of the world's population utilize

plastics to support its activities, ranging

from shopping, the use of household

furniture that Bebahan plastic base,

automotive to building materials. Plastic

has the advantage over other materials such

as strong, lightweight, flexible, rust

resistant, not easy to break, easy to color,

easy to set up, and good heat and electrical

insulators.

Plastic that has become a waste will

negatively impact the environment because

it cannot be degradable quickly. Plastic

waste that is removed indiscriminately can

also clog drainage channels, sewers and

rivers so that can cause flooding. Burned

plastic waste can produce substances that

are harmful to human health (Untoro Budi

Surono and Ismanto, 2016)

Plastic waste handling is popular as long as

it is with 3R (Reuse, Reduce, Recycle).

Recycling done by reprocessing goods that

are considered not have an economical

value anymore through physical or

chemical process or both so that obtained

products that can be utilized or traded

again. (Kumar, et al., 2011). One example

of action that aims to recycle (Recycle) is

to recycle plastic waste into Paving Block.

Paving blocks are made by using sand base material and using adhesive with plastic base material of low density

polyethylene (LDPE). The sand used in this study was obtained from the river and has a stock that is still

abundant. Then for adhesive that originally used cement then replaced using plastic garbage which is a low

density polyethylene (LDPE).

RESEARCH PROBLEM

In this study, the recycled plastic waste was mixed with sand to be paving

block. Paving block was made by using sand as basic material and

adhesive of plastic waste from the type of plastic bag or low-density

polyethylene (LDPE) as a substitute of cement. The problem is how the

effect of plastic mixture composition with sand upon water absorption and

porosity from the produced paving block.

PROBLEM LIMITS

To limit the problems examined for directional research in accordance with

the expected objectives, the basic assumptions and limitations of the

following are used.

1. In the process of making the test material sand grain size is assumed

according to the desired size of 3mm

2. Garbage plastic bag assumed to have the same characteristics.

BENEFITS OF RESEARCH

The benefits that are expected to be obtained from this research include the

following:

1. Can cope with environmental pollution by making plastic waste to be a type

of composite material LDPE.

2. Utilization of plastic waste as composite matrix.

3. Increase the economical value of recycled materials.

4. Can be a renewable science innovation in material fields that can be useful for

the community.

RESEARCH STEP

• The first step is washed sand to remove dust and other impurities and then dried naturally in sunlight

for 24 hours.

• Plastic waste is cleaned from dirt then dry in the sun

• Used plastic material counting with plastic counting machine.

• The process of mixing plastic waste with sand using mixer machine with a variation of temperature

200oC with some plastic composition: (1:3, 1:5, and 1:7) and 3mm sand grain size (6 Mesh)

• Printing materials made of sand and cement with the composition as above to be used as a

comparator.

• Printing process of materials with a pressing machine in order not to occur excessive voids.

• Remove the material from the mold.

• Cut the test specimen

• The observation of a composite physical form, which composite was successfully printed, was

observed whether any void was visible from the surface or not. Void should not be collecting

somewhere.

Water Absorption Chart

Based on the results on composite measurement of water

absorption percentage with variations in LDPE type plastics and

the sand that has been made resulted in the average water

absorption data from each sample as shown in Figure 4.1, it

appears that Differences in plastic mixture with sand affect the

uptake of water specimen. Based on the measurement results, the

highest average water absorption is owned by samples that have

a plastic comparison with the 1:7 sand. The lowest average rate

is derived from a plastic comparison with 1:3 sands. Because the

more content of LDPE into the mixture of paving block then the

absorption of water is lower and if more and more content of

sand, the higher the water absorption or the time of the

specimen. This is because (LDPE) does not absorb water, whereas

little (LDPE) causes more gaps (Porus) due to the lack of binders

in specimens.

DISCUSSION OF POROSITY TEST

The results of the measurement of porosity with the variation of sand and plastic that has

been made resulted in the percentage of the average porosity of each sample as shown

in Figure 4.2, shown that the average percentage of the largest porosity Obtained from a

variation of the plastic mixture with the 1:7 sand, while the lowest data is in the average

1:3 mix comparison, this is because the plastic composition in the mixture of 1:7, fewer

than 1:3 on the same volume, because at the Comparison of 1:7, as more sand than

plastic

Causing more cavities or voids due to lack of binders from

the sand itself and vice versa in a comparison of 1:3 due to

the amount of plastic more so that the specimen makes fewer

cavities or voids, and the printing process Also easier even

though there are still cavities or voids caused by air factor or

during the printing process because it is done in an open

space in a manual way. Can be seen from the micro structure

as follows:Picture (a)

Magnification 1:7

Conclusion

From the results of the research and discussion in previous chapters can be taken

several conclusions as follows:

1. The lowest percentage of water absorption is obtained from the 1:3 sand plastic

composition, the percentage which can be at 5.5%. Meanwhile, the largest

percentage of water absorption is obtained in the composition of 1:7 plastic and

sand mixture of 21.04%.

2. The percentage of porosity gained with the 1:3 mixed composition is also the least,

of 0.715%. While the mixture of plastic and sand composition is 1:7, the largest

percentage of porosity is obtained by 4.399%.
