Abstract

The treatment and packaging of wet vegetables such as mustard greens during the delivery process from farmers to consumers greatly affects the quality of mustard greens. In order for mustard greens to last longer, the right material is needed as a packaging medium for mustard greens. Good packaging for vegetables instead of plastic is banana leaves and teak leaves. In this study, we compared packaging with banana leaves, teak leaves and without packaging. Packaging treatment in the cardboard and outside the cardboard. The results showed that mustard greens treated in cardboard boxes with banana leaves decomposed within 7 days, teak leaves 5 days while without packaging for 4 days. The final temperature was 30.5 oC in the teak and banana leaf packages, while the unpackaged temperature was 29.5 oC. Mustard greens treated outside the cardboard box with banana leaf packaging decomposed within 6 days, teak leaves 4 days and without packaging only 3 days. The final temperature was 29.5 oC for banana leaves and teak leaves while those without packaging were 28.5 oC. From the results obtained, the treatment in cardboard and using banana leaf packaging has a long spoilage age.

Abstract

Sugarcane bagasse and eggshell waste are common types of waste found in Indonesia. This article introduces an innovation to utilize these two waste materials as bone implant materials, offering a way to increase their economic value. Bone implant materials primarily consist of SiO2 and CaO, both of which can be derived from sugarcane bagasse and eggshell waste. The process of making bone implants begins with the purification of sugarcane bagasse and eggshell waste to produce SiO2 and CaO compounds. Characterizations conducted at each stage of the reaction process in this research include FTIR, XRD, and SEM.The purification of sugarcane bagasse into SiO2 is carried out using a hydrothermal reaction, while the purification of eggshell waste is performed using the calcination method. Once the high-purity raw materials are obtained, the process continues with the production of bioactive glass. Bioactive glass is a biomatrix material used as a bone implant material. Its composition requires SiO2 = 45%, Na2O = 25%, CaO = 25%, and P2O5 = 5% (weight/weight). The sol-gel method is employed to produce the bioactive glass.After the bioactive glass material is produced, it is further characterized to evaluate its structure and properties. Additionally, bioactivity testing is conducted using SBF (Simulated Body Fluid) to ensure its safety when used as a bone implant and its interaction with body tissues.
