Pengaruh Pemakaian Sampah Plastik Ldpe (Low Density Polyethylene) Terhadap Paving Block Dengan Penambahan Admixture Silica Fume

---

ABSTRACT
The use of environmentally friendly materials in construction is an important
consideration in efforts to reduce waste, particularly plastic waste that is difficult
to decompose. This study aims to investigate the effect of using LDPE (Low Density
Polyethylene) plastic waste on the characteristics of paving blocks, particularly in
terms of compressive strength and water absorption, with the addition of silica fume
admixture as an additive. LDPE was chosen due to its abundant availability as
household waste and its potential as a partial replacement for fine aggregate. The
study was designed with a comparison of cement and sand aggregate mixtures with
LDPE variations of 10%, 20%, and 30%, plus 10% silica fume admixture, using
molds with dimensions of 10 cm in length, 10 cm in width, and 6 cm in
height/thickness. The dependent variables were compressive strength and water
absorption percentage, in accordance with SNI 03-0691-1996. The results showed
that paving blocks using LDPE increased compressive strength at the 20%
variation to 12.8 MPa at 28 days and reduced water absorption to 5.15%. Based
on the testing and comparison with SNI 03-0691 1996, the paving blocks in this
study still meet the quality standards of Class C as specified.
Keywords: LDPE, plastic waste, paving blocks, silica fume, compressive strength,
environmentally friendly concrete.
