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%.

Research studies of fermentation effects on processed chocolate have been made. The purpose of this study was to see the effect of different levels of fermentation of cocoa preparations (pasta, fats and powder) to the chemical quality and flavor. Harvested Cocoa beans will be treated fermentation. The treatment used was the time of fermentation namely: (A) Non fermentation, (B) Imperfect fermentation (4 days) and (C) Perfect fermentation (5 days). The parameters observed was: (a) chemical quality namely water content, fat content, pH, (b) organoleptic tests namely color, aroma, taste bitter (bitterness), texture. The results showed that fermentation of cocoa beans have real impact on levels of fat, water content and pH. Panelists gave the highest rankings for quality of organoleptic attributes of pasta, fat and chocolate powder from perfectly fermented beans. Processing of cocoa beans into refined products had levels of depreciation for each stage. 100 kg dried cocoa beans could produce 79.0 kilograms of chocolate paste, 48.7 kg of cocoa powder, and 26.5 kg of fat. Fermentation for 5 days is the best solution to improve the quality of processed chocolate.

Palm oil empty fruit bunch (EFB) is a waste from palm oil industry and commonly used as compost for soil breeding. EFB could be hydrolized into glucose using hydrothermal process with hydrochloric acid as catalyst. Eight gram of EFB in particle sizes (–30+40) mesh were hydrolyzed with HCl 10% 80 mL in a tube reactor. Reaction time were 2, 3 and 4 hours in temperature range 140-240oC. EFB decomposition did not increase despite of higher temperature while reaction time influenced the process significantly. EFB conversion was 47% in 4 hours and 240oC while in 3 hours resulted 34% same with 2 hours in 210oC. EFB decomposition did not influence glucose yield which was 23% in 2 hours 170oC, 24% in 3 hours 160oC and 6% in 4 hours 150oC. The optimum conditions of conversion were 2 and 3 hours with temperature range 150-170oC.Keywords: conversion, EFB, glucose, hydrothermal, pretreatment ABSTRAKLimbah tandan kosong kelapa sawit (TKKS) merupakan hasil samping dari industri minyak sawit dan terdapat dalam jumlah banyak. Sampai saat ini belum termanfaatkan dengan baik, biasanya dipakai sebagai kompos untuk pemuliaan tanah perkebunan sawit. Persentase TKKS sebesar 23% dari tandan buah segar (TBS) dengan komponen utama berupa selulosa, hemi-selulosa dan lignin. TKKS bisa dihidrolisis menjadi gula atau glukosa dengan proses hidrotermal menggunakan katalis asam klorida.
