Abstract

The increasing demand for peanut-based snacks has an impact on increasing peanut shell waste in Indonesia. The cellulose content in peanut shells is still relatively high, so it requires a long period for natural degradation. Though the waste can be converted and utilized in other forms, as a prebiotic. This far, inulin has been used as a prebiotic source. Products with inulin fortification have high prices, so we need to look for other cheaper ingredients. This research was conducted to test the ability of peanut shell waste extract as a prebiotic substitute material. To achieve this goal, peanut shells were extracted for cellulose. Streptococcus thermophiles probiotic bacterial growth test performed with a completely randomized design (CRD) pattern. The treatment factor used was crude extracts concentration of peanut shell waste. 0% was for the negative control, 20%, 40%, 60%, 80% and inulin were for positive control. Observation parameters in the research were the identification of colony morphology, gram staining, and growth curve analysis. The results of the study showed the crude extract of peanut shell waste affected Streptococcus thermophiles growth rate, even though it was not equivalent to the results of inulin treatment. The addition of coarse peel extract (40%) showed the most optimal growth curve pattern. The cellulose from peanut waste used as a carbon source for bacteria growth.Keywords: Peanut shell, prebiotics, Streptococcus thermophilus

Abstract

Ganitri (Elaeocarpus ganitrus) is one of the annual plants that grows in Indonesia, especially in Java. Ganitri seeds have not been fully utilized. Indonesian ganitri seeds are not widely known for their chemical content, so they are only used as jewelry and trade. This research was conducted to determine the potential of ganitri seeds as biodiesel feedstock. The research method used is the method of sochletation and maceration. The results showed that the effective content of ganitri seed oil was obtained by the sochletation method. The level of FFA (Free Fatty Acid) of ganitri seed oil is 2.8%, so preliminary action needs to be taken, namely the esterification process in the process of making biodiesel. From the results of the research conducted, ganitri seed oil can be used as raw material for making biodiesel but is less effective for mass production.

Abstract

Research on Biofiltotacum - The optimization of stem waste (Nicotianatabacum) aims to create a bio-filter from cellulose extracts of tobacco stems as a form of ultrafiltration membrane for river water filters. Tobacco stem waste can be utilized as an efficient and effective membrane feedstock. This research is done by phase inversion method. Quantitative data analysis was obtained with the calculation of acetyl content that is 16, 89%. Acetylation data obtained is smaller than the standard of 40%. The amount of acetyl content can be affected by several factors, including duration of acetylation process, temperature, stirring speed, acetate amount, and also solvent amount. In addition, the small amount of acetyl may be caused by the cellulose content in the tobacco rod is not yet optimally isolated.
