Edible film is one of alternative packaging which can consume and still protect product from losing nutrition, appearance, flavor, dehydrate and deteriorate at storage and isn’t damage environment. More research using local starch from sweet potato (Ipomea batatas L. poir) was studied. But, characteristic from sweet potato starch shows poor in quality. So, mixing starch with chitosan studied to make characteristic of edible film more useable for wide area. This research to know how is characteristic of edible film starchchitosan. One edible film use 0,8 mL glycerol or 20% (v/w) and chitosan’s soluble 1% acetate acid. One factor uses in this research is amount of chitosan with 3 level 0,5 gram; 1,0 gram; and 1,5 gram. Then, edible film analyzed physical (thickness, solubility and permeability) and mechanic (tensile strength and elongation). Result of research show more chitosan add significantly increased thickness and tensile strength of edible film and significantly decrease solubility and elongation of edible film. But, edible film show no significantly decrease of permeability. Adding more chitosan in edible film starch-glycerol increase edible film thickness to 0,13 –1,90 mm and decrease solubility to 66,87–58,20%. Tensile strength show increase to 1,27–6,90 MPa and elongation decrease to 79,71–46,98%. And for permeability of edible film decrease to 12,40–9,97 (g/ hour m2).

Pedada fruit contains 56.74 mg/100 g of vitamin C and 79% of water. One of the uses of this fruit is for a raw material of fruit ice cream. Objectives of this research was to evaluate quality of fruit ice cream made from padada fruit and young coconut juice with addition of Carboxy Methyl Celulose (CMC). Randomized completely design with two factors was implemented in this research. The first factor was proportions of pedada fruit and young coconut juice consisting of three levels, that was i.e., 25%:75%, 50%:50%, and 75%:25%. The second factor was CMC concentrations consisting of three levels, that was i.e., 0.1, 0.2, and 0.3%. The best quality of fruit ice cream was obtained from 25% padada fruit juice and 75% young coconut juice with addition of 0.3% CMC. The physical and chemical characteristics of the ice cream were a melting time of 11.11minute/10g, an overrun of 5.71%, a relative viscosity of 8.15 (Poiseuille x103), a fat content of 0.06%, a protein content of 1.29%, and a vitamin C content of 0.76mg/10g. The sensory characteristics of the ice cream were brownish, rather sour and sweet, and pedada-fruit aroma.

Quality is one of the important factors in producing lemea - a fermented bamboo shoots and fish. Objectives of this research were to find out effects of preparation and their interaction to produce the best quality of lamea. This research used randomized complete block design with two factors and three replications. The first factor was preparations (P) consisting of four levels, namely preparation by smoothing and stirring (P1), preparation by cutting and stirring (P2), preparation by smoothing and coating (P3), and preparation by cutting and coating (P4). The second factor was blanching (B) consisting of two levels, namely without blanching (B0) and blanching (B1). In order to determine its quality, lemea was observed for its content of lactic acid bacteria, total volatile nitrogen, moisture content, and protein content as well as its sensory characteristics (color, aroma, texture, and overall acceptability scores). Collected data were analysed for its variances and the results showed that preparation and blanching treatments significantly affected lemea’s total volatile nitrogen and sensory characteristics. The best lemea quality was obtained from combination treatment of blanching with chopped and stirred preparation (B1P2). The lemea had lactic acid bacteria of 10.1160 log cfu/g, total volatile nitrogen of 43.14 mg/100g, moisture content of 87.99% (b/v), color score of 4.34 (yellowish white), aroma score of 3.78 (rot), texture score of 4.53 (soft) and overall acceptance score of 3.90 (likes).

Achievement of the efficiency of the supply chain of organic vegetables PT. X needs to consider output in the form of added value and profit margins obtained from the input of delivery, fulfillment of requests, and risks faced by each actor. The purpose of this study was the management of supply chains of organic vegetables from farmers, entrepreneurs, retailers, and consumers in Cisarua, Bogor Regency, West Java. Based on the results of the analysis of value added by Hayami's method, it was known that retailers' profit margins tend to be bigger, but the contribution of value added is lower than that of farmers and companies. The results of risk measurement showed that the biggest risk index was in farmers due to the large risk of supply shortages. Measurement of efficiency using DEA showed that retailer actors were more efficient but tend to avoid risk. Achieving high efficiency at retailers indicated the ability to balance risk and revenue so that the delivery of organic vegetables in the supply chain was more efficient. Through a risk management mechanism with risk balancing and cost incentives because of the risk showed an increase in supply chain efficiency. This efficiency can be seen from the increase in the number of retailers 'demand and a decrease in supply / shipping inefficiency of farmers and companies in meeting retailers' demands.

The problem faced by the palm oil industry today is the instability of the Crude Palm Oil (CPO) yield. The condition of Fresh Fruit Bunches (FFB) starting from the time of harvesting to transporting to the factory, including during stockpiling at the palm oil mill, is an influential factor affecting the yield of CPO. This study aimed to find the factors causing instability of CPO yield in the palm oil industry. I-MR control maps and fishbone diagrams were used to analyze the factors that cause low CPO yields. From the data analysis for three years, the evidence of CPO yield was not statistically controlled. The causative factor of CPO yield instability included the quality of raw materials, production equipment, character of workers, and environmental conditions, with the dominating factor was the low quality of raw materials.

The development of bioethanol as fuel substitution is believed to overcome the potency of the world energy crisis including Indonesia. The bioethanol development can be done by increasing the production capacity of the existing bioethanol factory plant by improving yeast culture for enhancing the performance of the fermentation process. This study was aimed at obtaining a method of optimizing the ability of Saccharomyces cerevisiae fermentation that can be applied by the alcohol industry in Indonesia for increasing factory productivity, thereby reducing the cost of producing alcohol. In this study, the adaptation of Saccharomyces cerevisiae Watei and Saccharomyces cerevisiae Hakken I were adopted in environment condition with high ethanol content up to 13%. The results showed that the yeast was able to grow in environments with high ethanol content with higher specific growth rate and larger cell size than those within the original yeast. This condition showed that adapted strains can overcome stress caused by high ethanol. These results promise the good performance yeasts with ability in growing and performing metabolic activities in high alcohol-containing environment conditions
