Abstract

Bioarang is charcoal (one type of fuel) made from various kinds of biological materials, for example wood, twigs, leaves, grass that can be carbonized. biobriquette is an alternative energy  substitute for fuel produced from organic materials or agricultural waste (biomass) that is underutilized, especially durian shell waste. This study aims to look at the comparison of the quality characteristics of the durian shell biobriquette with the type of charcoal based on the percentage of volatile matter.  The making of this biobriquette uses 1: 2 pati janeng from the biobriquette weight, the biobriquette particle size is 80 mesh, the cylindrical biobriquette form. The results showed that the biobriquette produced had met the fuel quality standards for households. Level biobriquette of durian shell volatile matter is obtained 6%, and for the type of volatile matter charcoal is 5%. Based on the quality standard for volatile matter is a maximum of 15%. Volatile matter test for biobriquette durian shell obtained can be used as an environmentally friendly fuel.

Abstract

Jatropha sap (Jatropha curcas Linn.) is a natural ingredient that contains active tannins, flavonoids and saponins. These metabolic compounds can help speed up the wound healing process. One way to increase the effectiveness of using Jatropha gum is to formulate Jatropha gum extract. This study aims to determine the formulation of gel preparations with varying concentrations of Jatropha gum using HPMC base, to determine the inhibitory power of Jatropha gum against bacteria E. coli and S. aureus. The results showed that Jatropha curcas sap was not able to inhibit the growth of E. coli but had activity to inhibit the growth of bacteria S. aureus. The inhibitory power at each concentration is 10% (8 mm), 25% (10 mm), 50% (11 mm) and 100% (13 mm). The gel preparations made were Formula F1, F2 and F3. The concentration of Jatropha gum used was 1%, 3% and 5%. The results showed that the gel was in semisolid form and had different gel colors based on the concentration of jatropha gum. The higher the concentration of jatropha gum, the more concentrated the gel color obtained.
