Pembuatan Pavig Block Menggunakan Limbah Sandal dan Besi Tulangan

Abstract

Tingginya permintaan sandal di masyarakat berakibat pada tingginya jumlah limbah sandal. Limbah sandal memberikan dampak negatif terhadap lingkungan. Limbah sandal dapat dimanfaatkan sebagai bahan bangunan paving block. Penambahan limbah sandal dapat menurunkan kualitas paving block sehingga diinovasikan penambahan besi tulangan untuk meningkatkan daya kuat paving block. Tujuan penelitian ini adalah mengidentifikasi pengaruh penggunaan besi tulangan pada pembuatan paving block limbah sandal. Perencanaan pembuatan paving block dengan perbandingan 1:2 untuk semen, pasir, dan sandal karet jenis spon sebagai pengganti agregat halus sebanyak 10% dari total berat pasir. Terdapat dua perlakuan yaitu tanpa besi tulangan (P1) dan dengan penambahan besi tulangan (P2). Berdasarkan hasil penelitian sifat tampak P1 dan P2 tidak memiliki perbedaan, pada pengukuran ketebalan nilai P1 dan P2 memiliki nilai ketebalan 6 cm, nilai kuat tekan P1 dan P2 didapatkan hasil 3,04 Mpa dan 4,66 Mpa, nilai penyerapan air P1 P2 didapatkan hasil 19,07% dan 14,36%, nilai densitas P1 P2 didapatkan hasil 1,39 g/cm3 dan1,54 g/cm3

The high demand for sandals in society has resulted in a large amount of sandal waste, which negatively impacts the environment. Sandal waste can be utilized as a building material for paving blocks. However, the addition of sandal waste may reduce the quality of the paving blocks, which led to the innovation of adding iron reinforcement to improve the strength of the paving blocks. The objective of this study is to identify the effect of using iron reinforcement in the production of paving blocks made from sandal waste. The paving block production was designed with a 1:2 ratio of cement to sand, with sponge-type rubber sandal waste replacing 10% of the total sand weight as a fine aggregate. There were two treatments: without iron reinforcement (P1) and with the addition of iron reinforcement (P2). Based on the research results, the appearance of P1 and P2 showed no differences. In the thickness measurements, P1 and P2 both had a thickness of 6 cm. The compressive strength values of P1 and P2 were 3.04 MPa and 4.66 MPa, respectively. The water absorption values for P1 and P2 were 19.07% and 14.36%, respectively. The density values for P1 and P2 were 1.39 g/cm³ and 1.54 g/cm³, respectively
