Abstract

A study has been conducted on the manufacture of biofoam from cassava starch extract with the addition of peanut shell powder. There were 3 samples made in this study by heating using an oven (120°C, 140°C, 160°C) with the addition of magnesium stearate and ZnO. The quality characteristics of the synthesized biofoam were tested through water absorption tests, water content tests, leakage tests and biodegradable tests. The results of the water absorption test analysis obtained the percentage of each sample of 17.409%, 12.081%, and 4.049%. From these results, the temperature of 160°C which meets the SNI standard is 11.8682%. In the water content test, the percentage of each sample was 30.290%, 15.884%, and 9.615%. From these results, it has met the SNI standard of 26.12% except at a temperature of 120°C. In the leakage test, the results were obtained in the form of leaking samples on days 1, 2, and 4. In the biodegradable test, the percentage of each sample decomposed was 96%, 97%, and 100%, in the seventh week. Based on the biodegradable test, all samples can decompose well in a relatively fast time span and meet SNI, which is 100% for 60 days.

Abstract

Sifat sekali pakai dari styrofoam menimbulkan risiko lingkungan yang signifikan karena ketahanannya terhadap degradasi serta pelepasan partikel mikroplastik saat dibakar. Penelitian ini bertujuan untuk mengembangkan biofoam berbasis pati sagu sebagai alternatif biodegradable terhadap styrofoam konvensional. Biofoam diproduksi melalui proses pemanasan dan pemadatan pada berbagai variasi suhu untuk mengevaluasi pengaruhnya terhadap sifat fisik dan daya urai. Hasil menunjukkan bahwa semua variasi suhu menghasilkan biofoam yang terurai sepenuhnya dalam waktu 60 hari, memenuhi standar biodegradabilitas yang ditetapkan oleh Standar Nasional Indonesia (SNI). Namun, hanya sampel yang diproses pada suhu 140°C dan 160°C yang memenuhi standar daya serap air, dengan nilai berkisar antara 6% hingga 26,12%. Suhu optimal diidentifikasi pada 160°C, yang menghasilkan biofoam dengan ketahanan terbaik terhadap kelembapan dan kebocoran. Temuan ini menekankan pentingnya pengendalian suhu dalam proses produksi untuk mencapai performa fisik yang optimal. Biofoam berbasis pati sagu menunjukkan potensi yang kuat sebagai solusi ramah lingkungan dan berkelanjutan untuk aplikasi kemasan.
