Berdasarkan data Sistem Informasi Pengelolaan Sampah
Nasional (SIPSN)
Kementerian Lingkungan Hidup dan Kehutanan (KLHK), volume
timbulan
sampah di Indonesia pada tahun 2022 mencapai 36,22 juta ton.
Sampah plastik
menempati posisi kedua setelah sampah organik dari sumber
timbulan sampah
dengan proporsi jumlah sampah plastik di Indonesia sebesar
18,1% atau sekitar
6,55 juta ton sampah plastik. Tujuan penelitian ini, agar
mengetahui jenis mutu
bata plastik komposit yang dihasilkan dan dapat menjadi
produk yang ramah
lingkungan. Jenis penelitian ini merupakan eksperimental
skala laboratorium

ABSTRACT
Based on data from the Ministry of Environment and
Forestry's National Waste
Management Information System (SIPSN), the volume of waste
generated in
Indonesia in 2022 will reach 36,22 million tons. Plastic
waste occupies the second
position after organic waste from sources of waste
generation with a proportion of
total plastic waste in Indonesia of 18,1% or around 6,55
million tons of plastic
waste. The purpose of this study was to determine the type
of quality of the
composite bricks produced and it can also be an
environmentally friendly product.
This type of research is an experimental laboratory scale
using quantitative
descriptive methods, data analysis using Rancangan Acak
Lengkap or Completely
Randomized Design (RAL) and further testing Least
Significant Difference (LSD).
The percentage composition used in this research is
composite plastic bricks 1
(0%), composite plastic bricks 2 (10%), composite plastic
bricks 3 (20%),
composite plastic bricks 4 (30%), composite plastic bricks 5
(40%), and composite
plastic bricks 6 (50%). Tests for density, hardness,
compressive strength and water
absorption were carried out after 24 hour of age. The
highest average value in the
variation of composite plastic bricks (50%). The results of
the research on density
1,5109 g/cm3 composite plastic bricks 50%. The results of
the research on hardness
6,14. The results of the research on compressive strength
testing obtained the
highest average value in the variation of composite plastic
bricks (50%) of 22,8430
MPa. The results of the water absorption test obtained the
best average value on
the variation of composite plastic bricks (50%) of 0,15%.
The results of the
Completely Randomized Design (RAL) for hardness, density,
compressive strength
and water absorption (F Count > F Table) so that the
treatment had a significant
effect and the results of the Least Significant Difference
(LSD) test for density,
hardness, compressive strength and water absorption obtained
optimal results on
the interaction of composite bricks MLP 50%, FA 50%.
