This study is aimed at producing a biofoam cup made from sugarcane bagasse with tempeh mold (Rhizopus oligosporus). Soybean flour (SF) was added to promote the growth of mycelia, which could bind fiber matrix. The main materials were whole (B) and depithed (DB). SF weight ratios 1 : (SF1) 1.5 (SF1.5). Therefore, studied specimens labeled B-SF1, DB-SF1, B-SF1.5, DB-SF1.5. All cups analyzed for t...

Evidence for the role of chitinases in biocontrol by Trichoderma species has been well documented.Chit42 lacks a chitin–binding domain (ChBD) which is involved in its binding activity to insoluble chitin. The objective of the present study was to enhance antifungal activity of T. harzianum by overexpression of wild type and hybrid forms of Chit42 containing chitin binding domain. To produce chi...

Biofoam is an alternative packaging to replace styrofoam because it renewable and biodegradable. In this study, the coconut fibre were used in production of biofoam cup with addition commercial tempe yeast (Rhizopus oligosporus). The purpose study was produce which has characteristics water resistant, not easily crushed, decomposed. This conducted a factorial Block Randomized Design (BRD) consi...

Proses fermentasi menggunakan Aspergillus niger maupun Rhizopus oligosporus mampu meningkatkan kualitas nutrisi ampas tahu. Sehingga penelitian menguji kemampuan kombinasi antara jamur R. dan A. dalam proses guna peningkatan Penelitian ini bertujuan untuk mengetahui jenis kapang yang lebih efektif meningatakan limbah tahu sebagai sumber bahan baku pakan ikan, selanjutnya didesain rancangan acak...

In this study, the effect of different inoculum sizes Rhizopus oligosporus on solid-state fermented (SSF) cocoyam (Colocasia esculenta) was evaluated. The results study show that samples with R. at (5-30%) had statistically higher activity α-amylase, as well levels proteins and glucose, but significantly reduced pH reducing sugar contents (p<0.05) compared to control (0%) after 72 h fermenta...

Liquefaction is a phenomenon where the saturated sandy soil experiences highly excess pore water pressure and loss of effective stress between particles simultaneously due to an earthquake. It will have impact on building damage or failure which laid soil. Study location was selected at New International Airport in Kulonprogo, Yogyakarta built loose coincidentally categorized as earthquake zone...
