Abstract

The use of conventional plastic in the manufacture of Indonesian National Army (TNI) ration packaging has become an unavoidable standard because it provides strength, resilience and durability which is very important for protecting food and other materials. However, the use of conventional plastic in making ration packaging has become an increasingly pressing problem, especially regarding environmental sustainability. To overcome this problem, conventional plastic must be replaced with environmentally friendly plastic (biodegradable plastic). The method used is a literature review by comparing the Indonesian National Standards with literature from various journals. The results of literature research show that there is no biodegradable plastic that meets SNI 7818:2014. The mechanical properties and biodegradability of biodegradable plastics are influenced by the concentration of additives such as plasticizers and fillers, such as glycerol and chitosan.

Abstract

Biodiesel is a promising renewable energy source to replace conventional diesel fuel. This study aims to improve biodiesel production efficiency by utilizing a heterogeneous catalyst derived from chicken eggshell-based calcium oxide (CaO), modified with magnesium oxide (MgO). The catalyst was synthesized via co-precipitation and applied in both transesterification and interesterification reactions using crude palm oil (CPO) as feedstock. The optimum reaction was conducted at 65°C for 180 minutes with a 9:1 methyl acetate/methanol to oil molar ratio and 2.5 wt% catalyst loading. The modified CaO.MgO catalyst outperformed unmodified CaO, yielding 89.63% and 99.96% biodiesel via interesterification and transesterification, respectively. The catalyst characterization was performed using FTIR, XRD, and GC-MS, confirming the enhancement in basicity, crystallinity, and FAME content. This study demonstrates the potential of waste-derived catalysts in sustainable biodiesel production while addressing environmental waste issues.
