The problem of plastic waste in Indonesia is increasingly worrying due to its long degradation duration. Bioplastics made from starch are easily degradable in nature and have a lower contribution to environmental pollution. This study aimed to determine the effect of ZnO and glycerol additions on the thickness, tensile strength, elongation, Young’s Modulus, water absorption, and biodegradation of bioplastics. The results indicate that adding ZnO and glycerol has significant effects on thickness, tensile strength, elongation, Young’s Modulus, water absorption, and biodegradation. A high concentration of ZnO and glycerol was parallel to an increase in the thickness of bioplastic. A high ZnO concentration and low glycerol concentration increases the tensile strength and Young’s Modulus, but decreases the water absorption. Glycerol at high concentration and ZnO at low concentration increases the elongation. The addition of ZnO in a small amount positively affects the biodegradation of bioplastics.

Plastic packaging has dominated the waste, and the number is increasing every year. Candy plastic packaging waste is most often considered trivial because of its small size, so it is usually disposed of carelessly. Due to its non-biodegradable, it causes environmental pollution. Edible film packaging is an alternative to reduce the impact of candy packaging waste pollution. The purpose of this study was to obtain the optimum formula of the edible film between corn starch, carrageenan, and rice bran as a hard candy packaging with the Response Surface Methodology (RSM) Central Surface Composite Design using the Design Expert 10.0.7. The prediction data obtained is then verified and tested by t-test at a 5% reliance interval.The optimum formulation of RSM results is 3.4% of corn starch, 1.1% of carrageenan and 0.38% of rice bran with predicted response of water content of 14.51%, WVTR 61,06 g/m2/hour, viscosity of 258.8 cP, tensile strength of 107.9 kgf/cm2, elongation of 19.41%, and modulus of response young 586.28 kgf/cm2. The verification of the optimum formula had a moisture content of 14.37%, WVTR 63.34 g/m2/hour, viscosity of 244.9 cP, tensile strength of 96.9 kgf/cm2, elongation of 20.96%, and young modulus of 462.49 kgf/cm2.

The palm kernel shell (PKS) is the endocarp of the oil palm fruit that protects the kernel of the oil palm crops. PKS is a by-product of separating the kernel of the palm kernel nut This by-product tends to be used as a solid biofuel because of it’s high carbon content. Meanwhile, the need for clean water in Indonesia grows year after year. The increased production of clean water is accompanied by the use lot of chemicals as water purification medium. PKS is lignocellulosic biomass with a lot of potential because of its characteristics and contents, including the use of materials as adsorbents. PKS has been evaluated and shown to be useful in dealing with heavy metal pollution. The use of activated carbon-based PKS as an adsorbent has also been intensively investigated such as using various activation techniques including acid activation and steam activation at high temperatures. There will be variances in their adsorption capability and adsorption process due to differences in structural properties and functional groups, as well as originating from different biomass sources with different varieties.

Porang (Amorphophallus muelleri Blume) is a source of glucomannan in Indonesia, and a potential agent for diabetes mellitus treatment, apart from konjac. This study aims to determine the potential of porang flour formulation as a therapeutic agent for diabetes mellitus, especially type-2 diabetes mellitus. Soluble fiber, water absorption capacity(WAC), disintegration time, and viscosity of porang flour (PF) and porang flour formulation (PFF: consist of 85% porang flour, 1.03% k-carrageenan flour, 12% inulin flour, and 1.97% modified cassava flour (MOCAF)) were scrutinized. Twenty-eight male albino Wistar rats were randomly split into seven experimental groups. Five groups consisting of diabetic rats were treated using porang flour (300 mg/kg bw); low, middle, and high doses of porang flour formulation (100, 300, 500 mg/kg bw, respectively); and metformin (51.38 mg/kg bw). The rest were normal, and the diabetic (DM) control group. PF, PFF, and metformin were orally administered to the streptozotocin-induced diabetic rats per day for four weeks of the experiment. Fasting plasma glucose (FPG), Malondialdehyde (MDA) level, lipid profile, aspartate aminotransferase (AST), and alanine transaminase (ALT) levels of the blood plasma were measured, while the pancreas was used for immunohistochemical study and β-cells quantification. ANOVA was employed to analyze the data, followed by Honestly Significance Difference using Minitab version 17.0. The result indicated a significant effect of PF, PFF, and metformin on decreasing FPG and MDA and increasing the number of pancreatic β- cells in DM rats. Porang flour (300 mg/kg bw) and middle-dose PFF are potential therapeutic agents for type-2 DM.
