Abstract

Fucoidan is a complex polysaccharide compounds found in brown algae. Fucoidan exhibits various biological properties for disease prevention. There are various methods used to extract fucoidan from brown algae, such as using ethanol, acetone, HCl and microwave. This research aims to extract and characterize fucoidan from Sargassum sp. using simple methods with the variables on extracting solutions, temperature and time of extraction. Extraction solution used were water and HCl. Ttemperature used was 50°C, 70°C and 100°C  using 1, 2 and 4 hours. The result showed that the highest extraction yield was obtained from the extraction by water with 100°C and 4 hours of extraction. Fucoidan extracted by water has molecular weight of 57.77 kDa and 2.71 kDa, while fucoidan extracted by HCl has molecular weight of 46.43 kDa and 3.38 kDa. The proportion of high molecular weight fucoidan extracted by water was 52.24% compared with HCl was 44.10%.

Abstract

Bioethanol gel is a new form of liquid bioethanol that has been given a thickening agent. This type of bioethanol is believed could make its transportation and utilization safer. This study aimed to compare the carbopol and carboxymethyl cellulose as thickener agents and to characterize the bioethanol gel produced. In this research, carbopol and carboximethyl used for making bioethanol gel were1.5, 3, 4.5 and 6 g. Then flame color, length of flame and viscosity were tested. The best bioethanol gel produced obtained on the addition of carbopol 6 g. Its characteristics were clear white color, the flame color is blue reddish, length of flame per 5 g is 5 minutes 17 seconds, and viscosity 1,380,000 cP. The boiling water test result on 100 ml of water by using 15 g of bioethanol gel takes 16 minutes.

Abstract

Utilization of cacao pod shells waste into charcoal briquettes is a way to find an alternative energy that can be produced within household scale. The aim of the research is to produce charcoal briquettes from cacao pod shells and its characterization. Research was designed with two factors, which is charcoal size (30, 50, and 70 mesh) and the percentage of starch used (3, 5, and 7%). Charcoal briquette produced then tested its physical and chemical properties. In general, charcoal briquettes from cacao pod shells with a mesh of 30 and 7% starch gives the best results. This charcoal briquette have a moisture content of 6.52%, ash content 16.73%, density 0.96 g/cm3; levels of volatile matter 20.18%, bonded carbon content 56.58%, and calorific value 4163.11 cal./g. Most of the parameters have not been meet the quality standards for charcoal briquettes of the SNI, Japan, England, nor American.

Abstract

Aloe vera dodol is a traditional food of West Kalimantan that has short shelf life because of its microbial activity. Antimicrobial edible packaging could be used to maintain the quality of packaged food product actively.The purpose of this study is to prolong the shelf life of food products using antimicrobial edible packaging from durian peel and basil (Ocimum sanctum L.) essential oil. The research was conducted through 4 phases,i.e. the extraction of pectin from durian peel, basil essential oil distillation, Aspergillus flavus inhibition assay, and antimicrobial edible coating production incorporated with Ocimum sanctum L. essential oil. The results showed that pectin extracted from durian peel at pH 4.5 could give yield of 5.9% with a clear coat (Colourless).The concentration of Ocimum sanctum L. essential oil by 0.6% could inhibit the growth of Aspergillus flavus and prolong the shelf life when applied as an antimicrobial ingredient in edible coating.

Abstract

Tannery production process in Indonesia is still using chromium sulfate or mimosa in general. Gambier (Uncaria gambier Roxb.) extract could be used as material for tanners because it contains tannin. This study aimed to investigate the characteristics of tanned leather using gambier solution at pH 4 and 8. Standard tanning method was used which includes the processing of goat leather with salt, acid and then tanned with gambier extracts. Observation of tanned leather refers to the SNI-06-0463-1989-A and ISO 0234:2009. The results showed that characteristics of tanned leather with solution of gambier at pH 4 and 8 respectively i.e.: degrees of tanning 29.87% and 39.55%, tensile strength 279.94 kg/cm2 and 433.85 kg/cm2, leather conditions was limp, light gray colour and yellow, thickness of 0.12 mm and 0.11 mm, and density 0.74 g/cm3 and 0.74 g/cm3. Tanned leather from different pH conditions generally has the same characteristic and meet standards.
