Cellulose, the most abundant renewable resource, has received much attention as potential energy and carbon source for the production of useful products such as glucose, ethanol and fuels. The possibility of converting cellulose in bagasse enzymatically into glucose, after being loosened its complex structure chemically into primary one by using sodium hydroxide was studied. Bagasse was soaked in 6% sodium hydroxide for 12 hours at room temperature. This treatment resulted in loosening some cellulose bundle structure shown by release of lignin and hemicelluloses up to 32.11 and 42.87%, respectively and high water retention value of 15.90 (w/w). In this condition the delignifi ed bagasse could be saccharifi ed by crude cellulase enzym from Aspergillus niger. Saccharifi cation enzimatically of 2 g delignifi ed bagasse at 50oC pH 4,8 during 120 hours produced reducing sugar of 54.47 mg/100 ml.

Tempe merupakan produk pangan bergizi tinggi yang digemari dan diterima oleh masyarakat luas, tetapi umumnya memiliki kadar yodium yang rendah. Rumput laut yang kandungan yodiumnya cukup tinggi dapat digunakan sebagai bahan fortifikasi yodium pada makanan. Penambahan rumput laut pada tempe diharapkan dapat menjadi alternatif pangan sumber yodium untuk menanggulangi masalah GAKY (Gangguan Akibat Kekurangan Yodium). Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan tepung rumput laut Gracilaria sp. terhadap kadar yodium pada tempe serta mengetahui karakteristik yang dihasilkan. Perlakuan yang dilakukan adalah perbandingan kedelai dan tepung rumput laut 100:0; 97,5:2,5; 95:5; 92,5:7,5; dan 90:10. Perbandingan kedelai dan tepung rumput laut 92,5:7,5 merupakan komposisi terbaik yang menghasilkan tempe dengan kadar yodium 0,26 mg/g; nilai sensoris hedonik rata-rata 5 (agak suka), serta 100 gram tempe tersebut memenuhi 17,47% angka kecukupan gizi (AKG) yodium orang dewasa per hari. Studi ini menunjukkan bahwa tempe tersebut dapat digolongkan sebagai pangan sumber yodium karena telah memenuhi 15% AKG orang dewasa.ABSTRACTTempeh is a highly nutritious food that is popular and accepted by diverse community groups, but has low iodine levels. Seaweed, with a high iodine content can be used as a fortification ingredient to increase the iodine levels of the foods. The addition of seaweed in tempeh is expected to be used as an alternative food source of iodine contents to overcome the IDD (Iodine Deficiency Disorders) problem. This study aimed to determine the effect of the addition of Gracilaria sp. seaweed flour to iodine levels in tempeh and to determine the characteristic of the product. The treatments were 5 (five) compositions of soybean and seaweed flour at ratio of (100:0), (97.5:2.5), (95:5), (92.5:7.5), and (90:10). The composition of soybean and seaweed flour at ratio of 92.5:7.5 was the best composition that produces tempeh with an iodine content of 0.26 mg/g; hedonic sensory test results on average 5 (somewhat like) and 100 g of tempeh met 17.47% of the daily iodine requirements for the adults. This study showed that tempeh can be considered as an alternative food source of iodine content as it contributed to 15% of adultâ€™s daily nutritional adequacy.

Organosulfur compounds classified as dibenzothiophenes (DBTs) and their derivatives are contained in petroleum. When used as fuel, these substances release SOx emissions, thus contributing to air pollution, acid rain, and climate change. Therefore, it is necessary to reduce the content of these organic sulfur compounds in fuels and one way to achieve this is through bacterial desulfurization. This study reports the biodesulfurization process of a mixture of DBT, 4-hexyl DBT, 4,6-dibutyl DBT, and various organosulfur compounds in light gas oil (LGO). The experiment was conducted by treating 1 mL of aromatic organosulfur compounds with 100 mg/L in \textit{n}-tetradecane or 1 mL LGO with 5 mL mineral salts in sulfur-free medium, incubated at 27 °C for 5 days with shaking at 273 rpm. Gas chromatography analyses revealed that the growing Sphingomonas subarctica T7b cells desulfurized and converted 88.29% of DBT to 2-hydroxybiphenyl as a metabolite while a mixture of DBT and 4,6-dibutyl DBT was desulfurized at 86.40\% and 7.00%, respectively. Furthermore, the mixture of DBT, 4-hexyl DBT, and 4,6-dibutyl DBT had a desulfurization percentage of 84.40%, 41.00%, and 6.66%, respectively, after five days of incubation. The compounds were observed to desulfurize slightly better as single compounds compared to when mixed with other aromatic sulfur compounds.

The excellent quality of the fermentation process is closely related to microbes involved in the process fermentation. This study aimed to compare the microbiological changes and physicochemical quality of green coffee during 16 hours fermentation. Lactic acid bacteria and yeast were the predominant microorganisms found throughout the fermentation process. The total lactic acid bacteria and yeast reached the highest value of 9.31 log10 CFU/g and 9.10 log10 CFU/g respectively on the coffee bean and 9.30 log10 CFU/g and 9.10 log10 CFU/g respectively on liquid of fermented coffee bean. The quantity of microflora on the coffee bean and liquid of fermented coffee bean increased and reached its maximum value after twelve hours and decreased after exceed its peak, while fungi was no detected during fermentation. Sixteen hours fermentation significantly (P<0.05) influenced the bulk density, moisture content and bean weight/100 beans, bean amount/10 g and cause defect to green coffee such us “broken beans”, “brown beans” and “partly black beans” yet were not significantly affected (P>0.05) bean size and color of the green coffee. Throughout coffee fermentation, the acids on the green coffee increased from 5.33 ± 0.144 to 9.99 ± 0.144% and the caffeine on the green coffee decreased from 3.70 ± 0.017 to 1.66 ± 0.003%. Phenol content on the green coffee and its brews also decreased successively from 1381.58 ± 8.40 to 980.16 ± 10.07 mg GAEs/100 g and 922.25 ± 17.961 to 812.06 ± 12.660 mg GAEs/100 g. While for the antioxidants capacity, green coffee was more stable and its brews increased successively from 11564.28 ± 255.345 to 112 34.428 ± 174.377 mg GAEAC/L and 32326.24 ± 22.744 to 38658.62 ± 180.107 mg GAEAC/L. It can be concluded that coffee fermentation had more a positive effect on microbiological changes and physicochemical quality of green coffee.

The aim of the research was to find out the effect of turmeric used in the urutan formulationon the microbiological characteristic of urutan. In production of urutan, two strains of lactic acidbacteria (LAB), Lactobacillus plantarum U201 and Pediococcus acidilactici U318, were used asmultiple starter culture. The results showed that the growth of LAB increased after 24 hfermentation. The addition of 0.5-1.0% turmeric could enhance the growth of LAB. The additionof 1-2% turmeric suppressed the growth of Enterobacteriaceae to undetected level after 48 hfermentation. The growth of Staphylococcus aureus tended to decrease during fermentation, andthese bacteria were not detected on urutan which used turmeric of 1-2% after 96 h fermentation.At the initial of fermentation the growth of micrococci increased, and the bacteria decreasedgradually from 48 h fermentation until the end of fermentation. In general, using turmeric of 1%in urutan formulation could enhance the growth of LAB and suppress the growth of undesirablebacteria, such as the group of Enterobacteriaceae and Staph. aureus.

Aloe vera gel is a polysaccharide widely used as an edible coating because it contains glucomannan and lignin compounds that can inhibit respiration and transpiration in fruit. However, aloe vera gel has weakness such as easy to change its color, odor, and viscosity. Therefore, a stabilizer is needed, one of which is gum arabic. Storage temperature also affects the stability of aloe vera gel. The purpose of this study was to determine the concentration of gum arabic and the optimal storage temperature in stabilizing aloe vera gel as an edible coating. The study used a completely randomized design (CRD) with a factorial pattern. Parameters tested were viscosity, pH, color change, and sedimentation percentage. The results showed that the optimal concentration of gum arabic to produce stable aloe vera gel was 2% in cold storage (5 ± 1ºC), with stability up to 9 days of storage, on the condition that aloe vera gel has a pH of 4.58 ± 0.04, viscosity 40.67 ± 0.58 m.Pa.s, sedimentation percentage 8.13 ± 14.08% and color change (∆E) during storage 20, 09 ± 0.58. Aloe vera gel added with 2% arabic gum can be an edible coating on fruit or vegetables.
