Abstract

ABSTRACT Banana plants are well-known to contain diverse phytochemical compound. This study aimed to identify the antibacterial effects of Kepok Banana bunches (Musa paradisiaca L.) against Staphylococcus aureus bacteria. A laboratory analysis was carried out to determine the zone of bacterial inhibition. The experiment used completely randomized design with 3 treatments (50 µL, 70 µL Kepok Banana bunches extract and 50 µL Chloramphenicol as a positive control), each treatment replicated three times. The study was performed used wells agar diffusion. Data were analyzed by analysis of variance (ANOVA) and followed by Duncan Multiple Range Test (DMRT). Results showed that Kepok Banana bunches had potency as antibacterial agent. Treatments showed different (P<0.05) results in bacterial inhibition zones. Chloramphenicol produces the highest inhibitory zone (34.78 mm), while the difference in the concentration of banana bunches produces the same inhibitory zone (50 µL: 11.52 mm; 70 µL: 15.52). It is concluded that Kepok Banana bunches has potency to use as an antibacterial against Staphylococcus aureus.

Abstract

Sheep skin tanning has been carried out using a combination tanning material, namely 4% Aluminum and 6% Mimosa. Raw materials in the form of raw sheep skin weighing 2 kg. BHO, tanning, and post tanning processes are carried out to produce crust skin. The physical test characteristics are 0.7 mm thickness, 6 mm softness, 27.8 N/mm2 transverse tensile strength, 17.8 N/mm2 longitudinal tensile strength, 48.5 % transverse elongation, 45.8 % longitudinal elongation, 19.1 N/mm2 transverse tear strength, 18.9 N/mm2 longitudinal tear strength, and shrinkage temperature (Ts) 89oC. The physical test results were compared with the SNI 4593-2011 standard for sheep leather jackets. The results meet the SNI for sheep leather jackets.
