<![CDATA[Biogas is one solution to the use organic waste (livestock manure and vegetables). The aim of the research was to find out the effectiveness of livestock manure and fermentation of vegetable waste into biogas. This research was carried out using fermented vegetable waste for 10-12 days, then it was chopped and blended. The vegetable waste is then mixed with cow dung and water according to the determined variables. The mixture was put into a brown glass bottle and the bottle mouth was closed with a balloon and deposited for 8 days. Furthermore, the CO2 gas produced was released and start to deposite again for 20-30 days. Trapped methane gas obtained from in the balloon was then stored to measure the produced volume and pH and also the methane gas. The results obtained from the research that is were the best pH obtained from vegetable waste blender fermentation treatment (% water100 and the percentage of KS: SO was 75:25) was 7 and the largest volume was obtained from fermented chopped vegetable waste treatment (water% 300 and percentage KS: SO was 100: 0) of 78.73 cm3.]]>

<![CDATA[The biggest problem currently in Indonesia is the amount of garbage that accumulates and is not controlled anywhere, especially organic waste. There are also many methods to use waste. One of waste utilization is Biogas. Organic content contained in organic waste can be used as a substart source for anaerobic bacteria. Initial treatment of organic waste in this study used as a variable, namely chopped and blended. This initial treatment is done before it is mixed with other ingredients, ie cattle dung and water. 200% water is added to the reactor along with other variables. Temperature, pH and biogas volume were observed for 30 days. Initial treatment factor of organic waste as biogas production substand showed blend treatment with decay having higher biogas production than others, is 189.99 cm3 with a composition ratio of 50% cattle dung and 50% organic waste.]]>

<![CDATA[Rice bran oil as an alternative edible oil is promising to be developed. However, the presence of lipaze enzym which hydrolyze actively trigliceride into free fatty acid results rice bran quality can not be controlled and tend to degrade. Stabilization proccess was needed to overcome this isue. Stabilization with microwave heating has been carried out to study the effect of stabilization toward the quality of rice bran oil. The results showed that the highest percentage of oil mass 7.67% was obtained at medium power (power 2), stabilization time 1 minute and the extraction waiting time for 0 week. Meanwhile, the levels of free fatty acids tended to be constant when the proccess was carried out at power 3 (high power) for all stabilization times. Microwave heating was effective enough to reduce the lipase enzyme in rice bran so as free fatty acid content did not increase significantly.]]>

<![CDATA[Falling film evaporator is a constructed equipment for concentrating dilute solution that are sensitive to heat flowing form a thin film. This research aims to study the evaporation of cane juice concentrated with air flow on falling film evaporator and knowing evaporation rate occured in falling film evaporator used. In the process, cane juice from plant pumped to the falling film evaporator that used in this experiment. This research used concentrated cane juice and air flow rate for variables of this experiment. Cane juice flow from top of evaporator through distributor to form thin film and air flow from the bottom of evaporator. After that, temperatur of pipe wall, inlet and outlet temperature of cane juice and air were measured. This experiment concluded that the highest concentration of outlet solution is 59 brix for liquid flow rate 154 l/h and air flow rate 10 m3/h, and the other hand inlet solution concentration 51 brix. Optimum evaporation rate is 35 kg/m2.h for 51 brix and air flow rate 10 m3/h.]]>

<![CDATA[Cane juice is the main raw material in sugar factories. The processing of cane juice to produce the highest quality sugar must be through the proper evaporation process. If the evaporation temperature is too high, the cane juice can be damaged and this will affect the quality of sugar produced. The type of evaporator that is often used to reduce water content in food is falling film evaporator. This study obtained to determine the effect of the flow rate of cane juiceon the temperature distribution at the interface and wall. This research was conducted using Matlab Software and the Runge-Kutta Method. The research variables used were the flow rate of 154, 243, and 301 l/hr and the air flow rate of 4, 8 and 10 m3/hr. The results showed that the smaller flow rate of the solution, the smaller temperature of the solution at the interface with the same position. The temperature distribution on the wall has increased at the beginning of evaporator operation, but then decreased due to evaporation.]]>

<![CDATA[Grumusol soil is a type of soil that contains significant amounts of silica. Silica content in grumusol soil can reach up to 90%. The aim of this research was to determine the characteristics of silica nanostructures in Grumusol soil. The stages of the research were carried out including the preparation of raw materials, silica extraction, and XRD analysis. The raw material preparation stage is carried out by cleaning the grumusol soil from dirt. The second stage was carried out by synthesizing silica with the base extraction method and followed by acid deposition. The final stage is X-Ray Diffracion (XRD) analysis. The results of the research that has been carried out is the FWHM value of 0.0900 (<0.1) which indicates that the crystals produced have very good crystals with a very regular structure. The crystal size which includes nanosilica is 39.5076-48.6633 nm for 3M NaOH with 1 and 3 hours extraction time and 5M NaOH with 1 hour extraction time]]>
