Sintesis Komposit Selulosa Serbuk Gergaji Kayu Kamper-Limbah Plastik Ldpe (Low Density Poliethylene) Dengan Reagen Fenton Sebagai Agen Pengkopling

Abstract

This research was on the synthesis of cellulose composites from camphor wood sawdust with LDPE waste (cellulose-LDPE) and Fenton reagent (H2O2/Fe2+) as the coupling agent. This study was divided into three steps: preparation, variation of LDPE composition and H2O2 concentration, and characterization. Preparation was done with cellulose extraction of sawdust and LDPE plastic waste purification. Variation was performed to determine the effect of compositions of LDPE on composites celullose-LDPE and H2O2 concentration on Fenton reagent. Characterization was done by testing the physical properties and functional groups using FTIR analysis. The best values of the physical property were obtained from cellulose-LDPE composition ratio of 1:5 on 1.5% H2O2. These were MOE (Modulus of Elasticity) of 12.71 MPa, MOR (Modulus of Rupture) of 200.24 MPa and density of 0.7936 g/cm. FTIR analysis showed the higher the composition of LDPE, the higher the wavenumber for OH and the increase of H2O2 concentration increased the C-H wavenumber functional groups.

Pengembangan Wood Plastic Composite (WPC) Melalui Pemanfaatan Limbah Plastik dan Serbuk Gergaji Kayu

“…Untuk polymer jenis termoplastik penyatuan campuran material membutuhkan temperatur dan tekanan. Seperti pada pencetakan dengan proses hotpress (Slamet, 2013) (Nurwendi, Simpen, & Negara, 2016) dan injection molding (Gurau & Ayrilmis, 2018) (Bledzki, Mamun, & Volk, 2010) atau proses pembuatan tanpa tekanan seperti layup (Yudhyadi & Sari, 2013).…”

“…Studi tentang karakteristik WPC telah banyak dilakukan. WPC dikembangkan menggunakan berbagai jenis pasangan plastik-kayu, diantaranya; Kayu sengon-polyester (Rahman, Sudarisman, & Nugroho, 2018) kayu kelapa-resin epoksi (Poyoh, Rauf, & Lumintang, 2013) (Puja, 2010), kayu kamper-LDPE (Nurwendi et al, 2016), kayu jati-HDPE (Bootkul, Butkul, & Intarasiri, 2017) pinus-PP (Gurau & Ayrilmis, 2018), serat kulit durian (durian husk fibre)polystyrene (Chu et al, 2018), daun dan tangkai cabai-PP (Valles-Rosales, Rodríguez-Picón, Méndez-González, del Valle-Carrasco, & Alodan, 2016), serat serabut kelapa-PVC (Rimdusit, Damrongsakkul, Wongmanit, Saramas, & Tiptipakorn, 2011), limbah bongkaran konstruksi, CDW-HDPE (Hyvärinen, Ronkanen, & Kärki, 2019). Mahoni-resin polyester (Gapsari & Setyarini, 2010), mahoni-PP (Vedat, 2020).…”

“…Pemilihan coupling agent pada pembuatan WPC didasarkan pada pasangan jenis plastik dan reinforced-nya (natural fibre). Fenton (H2O2/Fe2+) digunakan sebagai agen pengkopel komposit campuran kayu kamper dan LDPE (Nurwendi et al, 2016), Maleic anhydrid (MAH) digunakan sebagi agen pengkopel komposit campuran kayu pinus dan polypropylene (PP) (Gurau & Ayrilmis, 2018).…”

Perancangan dan Analisis Kekuatan Rangka Cetakan Komposit Kayu-Plastik Menggunakan Finite Element Analysis

“…Untuk struktural komposit terdiri dari laminates [4] dan sandwich panel [5]. Proses pencetakan WPC dapat menggunakan proses hotpress [6], [7], injection molding [8], [9], atau lay-up [10].…”
