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.

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%.
