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.

The skin is an organ of the human body that functions to protect from outside influences. Damage to the skin will interfere with human health so that the skin needs to be protected and maintained its health. One of the things that causes skin damage is free radicals. To prevent skin damage from free radicals, an antidote is needed, namely antioxidant compounds. One source of natural antioxidants is petai bark extract (Parkia speciosa). In this study, petai bark extraction was carried out by using ethanol solvent. The dried petai powder was macerated with ethanol solvent for 24 hours, then solvent separation was carried out by using a rotary evaporator so that the extraction was concentrated green. The antioxidant activity in petai bark extract was observed through qualitative tests using DPPH reagent. The test results showed that the positive petai bark extract had antioxidant activity. The final stage of this study was to mix petai bark extract with skin lotion preparations. Based on the results of this study, petai bark waste which was originally of non economic value can be optimized to be an unique product and has high benefits.

At present the need for fossil fuels is very high, while reserves in nature are decreasing. For this reason, innovation is needed to find alternative energy from fossil fuels to alternative energy that is more environmentally friendly and can be renewed. The sugar factory as one of the Dutch heritage industries that produces solid waste in the form of bagasse can be used for boiler fuel. While the boiler exhaust gas (flue gas) from the chimney generated from burning fuel also causes air pollution can be used for drying bagasse so as to reduce the impact of pollution caused by the exhaust gas.The use of bagasse with a moisture content of around 49 - 52% as boiler fuel as one of the causes of burning in the combustion chamber is not perfect and causes air pollution. The high temperature of the smoke gas coming out through the boiler chimney around 2200C has a heat content of 13475.72 kW and still high levels of water in the pulp can certainly be used to dry bagasse using a dryer (Rotary Dryer) Through the use of flue gas that is wasted on the boiler chimney for bagasse drying, it can increase the heat value of bagasse 50,544 x 106 Kcal / hour for the production of bagasse 30 tons / hour, reduce bagasse water content up to 35,1%, increase thermal efficiency and reduce pollutants released into the surrounding environment.

Salt is one of the community and industrial consumption products that have the main content of sodium chloride (NaCl). The present quality of the salt product contains about 90-93% sodium chloride, and the other is known as an impurities of calcium (Ca), magnesium (Mg), potassium (K) and sulfate (SO4) ions. The presence of these impurities will decrease the quality of the salt product, so a method is needed to decrease the content of impurities in the salt product. One of the methods that can be used to reduce the levels of impurities such as Ca, Mg, K and sulfate (SO4) ions in salt solution is ion exchange method. In this study we studied the effect of cation resin amount (50-150) grams per liter of salt solution and anion solution (150 grams) and contact time (5-25) minutes on removal of Ca, Mg, K and SO4 ions. The study was conducted in a stirred tank with a fixed rotation speed of 200 rpm, and the initial quality of the salt solution contained Ca ions: 0.07%, Mg: 0.09%, K: 0.04% and SO4: 0.4%. Based on the result of the research, the removal of Ca ion: 93.6%,Mg :78.93%, K : 25.00% dan SO4 : 85.47 %at condition of cation resin amount: 150 gram / liter and contact time 25 minutes
