The quantity of waste water from domestic and industrial activities has increased significantly over the year, equivalent with increasing production of sewage sludge (schmid, 2000). Sewage Sludge high contents of organic and derivatives (Ammonia Nitrogen (NH4+), Nitrate, Nitrite) and also levels of COD and BOD that exceed the quality standard. Anaerobic Granular Sludge – Sequence Batch Reactor (AGS-SBR) is a kind of Waste Water Treatment Plant (WWTP) which combine the biological treatment, aeration and sedimentation process into one reactor. AGS-SBR is able to reduce organic pollutants, COD and BOD above 60%. In cycle process of AGS-SBR is also able to optimize methanogenesis process in the growth of microorganisms to convert biomass (sewage sludge) became biomethane. Hydrothermal of rice husk is able to produce substrate that serves as a growth medium for microorganisms. The addition of rice husk (SP) and hydrothermal rice husks (SPT) can inffluence the biomethane production from sewage sludge with variation of hydrothermal temperature of rice husk 110oC and 175oC. The results of this study obtained the average of biomethane production is 0,0458 with the highest content is 0,219 on SPT 110 and the average of biomethane production on SPT 175 is 0,0483 with the highest content is 0,223

Palm oil is one of Indonesia's leading export commodities. By 2020, the target of crude palm oil (CPO) production in Indonesia is 30 million tons. It is predicted that such production target is accompanied by a consequence of palm oil mill effluent (POME) emission as waste water, which will reach 90 million tons of POME waste per year. POME has high organic content which are characterized as chemical oxygen demand (COD) values, which ranges from 50,000 - 200,000 mg / L and pH values ranges from 4-4.5. Untreated POME is a serious environmental problem and therefore POME processing is urgently needed. One of the ideas is converting POME into more valuable products, by biosynthesis of omega-3 fatty acids from POME with anaerobic processes. The common product collected from anaerobic digestion is biogas. This study, however, intended to stop the process in the intermediate product, which is a series of organic acids, without biogas formation. The study aimed to explore the effect of controlled air injection in anaerobic processes on acid productions as the intermediate product in anaerobic digestion. The result showed that limited air injection (microaeration) improved process performance, especially with respect to acid production. Whereas through GC-FID analysis, the profile of saturated and unsaturated fatty acids was obtained. The acids have the potential to produce omega-3 fatty acids such as the appearance of nervoic, cis-eicosadienoic, cis-eicosapentanoic, and linolenic acids, with the peak of appearance occurring at different process durations. This preliminary study indicated that the biosynthesis of omega-3 fatty acids from POME through the anaerobic process was possible to be carried out but further study would be needed for process optimization.

Alkanolamide is an amide compound widely used in chemical, cosmetic and automotive industries. This compound has a "detergency" property because it has an amphilic molecule. the raw material that used is methyl esters, but the use of methyl esters needs to be considered because it can cause excessive foam in its use. This study uses castor oil as a raw material for triglycerides. Because of its nature, the alkanolamide can act as a surfactant. Hence, the surfactant of alkanolamide type environmentally-friendly and biodegradable surfactant from renewable sources. This study aims to identify amide compounds from reaction between triglyceride and diethanolamine with KOH catalyst. From the FTIR analysis result, the C=O compound formed has a wavelength 1618,88 cm-1, the best result of GC-MS is the compound diethanolamide oleat with 38% similarity.

ABSTRACT: This study aims to determine the quality of water hyacinth compost in physical and chemical properties. Water hyacinth is considered a weed that damages the aesthetics and aquatic environment in the Lut Tawar Lake tourist area. A solution is needed to overcome these problems, one of which is composting. In order for composting to take place faster, an EM-4 activator will be used which will give good quality. This research method uses one replicate with three treatments (K1 and K2 using EM-4, and K0 without EM-4). This study was conducted in two stages, that are the composting and characterization stages. The composting process is let runs for 60 days. Checking every 5 days is turn upside down and physical observation. After the composting process, is determined the pH, temperature and characterization. Characterization is done to determine the levels of C, N, P, K, Ca and Mg. The results of this study showed that EM-4 is effective for carbon (C), phosphorus (P) and calcium (Ca) grade. The grade of macro nutrient (C, N, P, K), micro nutrient (Ca) and temperature of water hyacinth compost are suitable with SNI.

Packaging is a protection of food product to maintain the quality and durability of food. The aim of this study was to produce edible film as sapodilla fruit preservation, to get the optimum composition of glycerol and beeswax mixture and to get the optimum characteristics of edible film based on cassava peel starch. The methodology of this study was use 3 grams of cassava peel starch with glyserol consentration range 0,75 to 1.25% v/v and beeswax consentration range 1 to 3 w/v.The parameters tested were fruit weight loss, thickness, tensile strength, elongation percentage and solubility. The results showed that the lowest weight loss value were obtained on the addition of 0.75% glycerol and 3% beeswax which were 3.3% of weight loss in 7 days.

Feed storage and packaging will be effected the quality of phisical, chemist and microbiology. Packaging are one of methode for protecting quality from damage of environment. This research to determine the effect of packaging type and storage time for broiler starter feed. This research using methode statistical Complete Randomized Desing Factorial (5x7) with three replications. The fixed variable in his research are Broiler Starter Feed. The first independent variable is the type of packaging (glass bottle, plastic bottle, aluminum foil vacuum plastic, vacuum plastic, and plastic seal) and the second independent variable is storage (14, 169, 338, 506, 674, 842, 1010 hours). The dependent variables were research are water content test with using methode SNI.01-2891-1992 and Crude Protein testing with kjeldahl methode using AOAC 2005, Chapter 4 Item 4.2.11. method 2001.11. Analysis data by using comparison of graphic regression. The maximum results showed that aluminum foil vacuum plastic container with water content of 10,8137% and crude protein 22,4661% at 842 hours storage (± 5 weeks), water content regression are y = 0.0003x + 10,636 with R2 = 0,9085 and crude protein regression y = 0,0007x + 23,07 with R2 = 0,9477. All test results with various packaging methods and storage time conducted in this study are still in accordance with the standard of feed starter broiler SNI 8173.2.2015 with a maximum water content of 14% and crude protein at least 20%.
