Abstract

Gulinggang (Cassia alata Linn) leaves extract has secondary metabolite compounds such as alkaloids, saponins, tannins, phenolic, triterpenoids, quercetin and steroids. These compounds are very useful, for example as an antifungal substances. The objective of this study is to utilize gulinggang leaves extract to produce antifungal bath soap. Gulinggang leaves were extracted by maceration method using ethanol solvent ratio 1:4 for 3 days. This extract was applied to the soap base formula using variations 0%, 5%, 10% and 20%. The organoleptic parameters of the body soap bar, such as aroma, texture, color, total panelist acceptance, and also the pH were tested. The inhibitory test was performed using Candida albicans fungus. The results showed that 5% of gulinggang leaves extract on soap gave the best result with organoleptic value 3.70; pH 9.76 and the mean diameter of the fungal resistance was 15.00 mm.Keywords: antifungal, Candida albicans, Cassia alata Linn, extraction, ethanol

Abstract

Material characteristic showed that the rubber seed shell (RSS) has good potential to be used as the main material of biopellet with low ash content and high calorific value, while ater bamboo (Gigantochloa atter) has good potential to be used as biopellet additive because has high lignin content, so that it can be used as natural adhesive. The purposes of this research were to study the utilization of CBK and ater bamboo into biopellet and to analyze the quality of biopelet that has been produced. The compositions of CBK and ater bamboo were 100%:0%, 95%:5%, 90%:10%, 85%:15%, and 80%:20%. Pelletization process was done at pressure 597.24 kg/cm2, temperature 150oC, for 10 minutes. The best quality of biopellet was produced on the formulation of 85% CBK and 15% ater bamboo. It has 4.23% of moisture content; 0.84% of ash; 79.44% of volatile substances; 15.48% of fixed carbon; 4472.41 kal/g of calorific value; 8.30 mm of diameter; 32.66 mm of length; 1063.87 kg/m3 of bulk density; 91.93% of mechanical durability; 0.21% of nitrogen; 0.05% of sulphur; and chlorine content was less than 0.10 ppm. The best quality of biopellet has fulfilled the requirement of Indonesian Standards (SNI 8021: 2014), while based on European standards (EN 14961-2), biopelet had one parameter that didn’t fulfill the requirement, the mechanical durability (min. 96.5%).Keywords : Biopellet, alternative energy, rubber seed shell, ater bamboo (Gigantochloa atter)
