Salix Tetrasperma Roxb. is a plant that found in Indonesia were used as traditional medicine such as diabetes and wound healing. In this study, a flavonoid compound of the ethyl acetate extract of Salix tetrasperma Roxb. leaves was isolated by chromatography technique and the antioxidant activity was determined by DPPH assay. The isolation led to obtain 5,7-dihydroxy-3'-methoxyflavone based on NMR spectra. The ethyl acetate extract exhibited the highest antioxidant activity with the IC50 is 65.89 µg/mL. This study shows that the Salix tetrasperma Roxb. has good potential as source of antioxidant agent.

The crisis in petroleum is caused by the diminishing supply of petroleum resources from nature. This phenomenon encourages researchers to continue to look for processes and methods to produce energy from other resources. One of these ways is to produce energy that can be utilized from waste, including converting waste cooking oil into biofuel. This method not only could provide a source of renewable energy, but also help resolve the issue of household waste. The process used to produce biofuel from waste cooking oil is by catalytic cracking, where waste cooking oil after pretreatment is converted into biofuel in the flow reactor with H-USY catalyst. In this research, the reaction temperatures used are 400 °C, 450 °C, 500 °C and 550 °C and reaction times are 30, 45 and 60 minutes with the mass ratio of the amount of waste cooking oil to the amount of catalyst used is 40:1 (w/w). The highest yield of liquid biofuel product was obtained at 60.98%. The use of H-USY catalyst shows that the distribution of components contained in biofuel are 28.02% of diesel products (C 17 -C 20 ), 23.96% of gasoline (C 6 –C 12 ) and 7.78% of Heavy oil (C 20 >) in catalytic cracking of waste cooking oil with a reaction time of 45 minutes at a temperature of 450 °C.

Catfish (Pangasius hypophthalmus) fat is a waste that has not been used optimally, especially in the use of soap. This study aimed to determine the effect of operating conditions are temperature, reaction time, and the ratio of volume between catfish oil and KOH. Soap can be formed by saponification reaction with strong alkali by hydrolyzing catfish oil with variations in the volume ratio of reactants (1:2, 1:3 and 1:4), temperature (75 °C and 95 °C) and reaction time (45 minutes and 75 minutes) with a constant stirring speed of 300 rpm. In the variation of the volume ratio of reactants, temperature and reaction time carried out in this study, a good liquid soap obtained is the volume ratio of reactants 1:3, temperature 75 °C and reaction time 45 minutes with pH 9.3 and free fatty acid 2.27%. The soap products produced have met SNI No. 06-4085-1996.

ZSM-5 is known as a heterogeneous catalyst in the process of petroleum cracking. Zeolite has narrow pores so it needs synthesis to form mesopore so that reactant molecules can enter the active site in ZSM-5 mesopore. In this study, mesopore formation was carried out by adding Si/Al components with a ratio of 20 derived from tetraethyl orthosilicate, aluminum isopropoxide and TPAOH template with hydrothermal process. The resulting ZSM-5 was characterized using x-ray diffraction, scanning and electron microscopy (SEM). The XRD characterization results showed that the ZSM-5 synthesized to form mesopore was seen from a fairly high peak intensity in the range at 2-theta were 8.11, 9.01°; 23.27°; 23.49°; and 24.13°. The results of this study already have the same structure as the commercial ZSM-5. Characterization of SEM-EDS showed that Si-Al and Na elements in ZSM-5 were 96.43%, 3.56% and 0% wt, respectively. With a magnification of 20000x, this cluster is quite homogeneous even though the crystallization formed is not well aggregated. This ZSM-5 catalyst will be applied to the process of biomass into bio-oil.

The pyrolysis bio-oil which has been studied by many researchers has typically contained a high amount of water, around 20-30%. In this research, the effective bio-oil purification using chemical demulsification method has been studied to reduce the amount of water by breaking down the water-in-oil emulsion on pyrolysis bio-oil. A various dosage of chemical demulsifier (100 ppm, 150 ppm, 200 ppm, and 250 ppm) has been added into the pyrolysis bio-oil and the water separation over time also been observed. The temperature of bio-oil (30, 40, 50, 60, and 70 °C) was also studied as a factor that could have a significant effect on the demulsification process of pyrolysis bio-oil. After the injection of 250 ppm of demulsifier at 30 °C, the water separation reached a maximum of 72% in 60 minutes and could reduce the water content from 25% to 8.5%. At the temperature of 60 o C and 250 ppm of demulsifier, the water separation reached a maximum of 96% in 35 minutes, and successfully reduced the water content from 25% to 1.3%. Finally, it has been concluded that this bio-crude purification using chemical demulsification method could be applied to effectively reduce the amount of water from pyrolysis bio-oil product.

In this work, the catalytic gasification process of coal was studied at different operating temperatures and catalyst weights. The purpose of this study was to study the characteristics of coal oil produced through the gasification process using Nickel Molybdenum (NiMo) catalyst. The effect of adding NiMo catalyst with variations in weight of 0%, 5%, 10% and 15% for different gasification temperatures (375 – 385 °C, 430 – 440 °C, and 475 – 485 °C) were studied on coal with a calorific value of 6,400 kcal/kg. The process was done in fluidized bed reactor under atmospheric pressure and an air flow rate of 2 liters/minute was flow for 60 minutes. The results showed that NiMo is effective as a catalyst in the gasification of coal at 430 – 440 °C, the addition of 15% weight of catalysts produced coal oil with a yield of 9.35% and the composition of hydrocarbon consists of 59.75% of aromatics, 26.42% of aliphatics, and 7.34% of phenolics. Compared to coal oil without catalyst give a yield of 6.56% with 57.33% of aromatics, 17.44% of aliphatics, and 16.03% of phenolics. This showing that NiMo catalysts have a high selectivity to increase aromatic and aliphatic hydrocarbons in coal oil.
