Jackfruit is a potential tropical fruit as raw material for food industry. Jackfruit could be processed by co-crystallization technique to extend its shelf life and increase its value. This research was conducted to study and to determine the shelf life of jackfruit powder extract. Shelf life test is conducted using variety of treatments such as: anti-caking types and temperature storage. The results showed that the shelf life of the jackfruit extract powder using anti-caking of magnesium oxide (MO), magnesium carbonate (MC), dan magnesium silicate (MS), which is store in the temperature of 27°C, were: 8.06, 5.42, and 5.5 months respectively. The variation of anti-caking type was significantly affect the product shelf life. The effect of storage temperature on the product shelf life is more significant for the product using anti-caking MO compared with product using anti-caking MC and MS.

Research utilization of liquid smoke from oil palm empty fruit bunches of raw rubber has been made to utilize solid waste from industrial processing of oil palm empty fruit bunches of oil palm so that it becomes economically valuable products. This research has been done by pyrolysis of oil palm empty fruit bunches at a temperature of 400oC for 5, 6, 7 and 8 hours. The results show that the pyrolysis liquid smoke oil palm empty fruit bunches for 8 hours give a high concentration of phenol and acetic acid, respectively 5% and 0.454%. Liquid smoke that has been obtained is used as a coagulant in raw rubber plantation crops of the people residing in the village of Ambawang, Kubu Raya District, West Kalimantan. Results of treatment of liquid smoke on raw rubber show that the rubber products that have been frozen and dried are superior in terms of color, smell and drying time compared with the treatment of formic acid and water battery which has been added so far on raw rubber by the local rubber farmers.

Adsorption technology is one of the technologies that can be applied to control exhaust emissions. This study aimed to utilize the skin biomass waste shell of coffee beans as activated carbon to absorb CO and NOx emissions in vehicle exhaust. Conversion of coffee beans shell into carbon was obtained at 31.14% at 450 oC. The absorption of exhaust emissions was done on four-wheeled diesel vehicles by placing activated carbon in the flue gas channel with two variations of pellet and hollow briquettes. The results showed COE emission reduction of 6.62-39.02% and NOx exhaust gas reduction of 13.08-39.05%. The absorption process also greatly influenced the mechanism of contacting exhaust emissions with the adsorbent. From the results obtained by activated carbon with hollow briquette form gave higher percentage of CO2 and CO2 emissions elimination compared to activated carbon in pellet form.Keywords: acivated carbon, adsorpstion, coffee bean shell, emission gasABSTRAKTeknologi adsorpsi merupakan salah satu teknologi yang dapat diterapkan untuk mengontrol emisi gas buang.

Flocculation is a feasible method for harvesting microalgae due to its lower cost. This research aims to optimize the flocculation efficiency in harvesting biodiesel-producing microalgae. Flocculation process was conducted towards microalgae cell suspension on 0.2-1 g/L range concentration by applying magnesium ions (1 until 5 mM) at alkaline condition (pH 9-12) in 30 and 60 minutes using neutralization and sweeping. The result showed that magnesium ion concentration, pH value and biomass concentration had significant effect on the efficiency of microalgae cells flocculation, while flocculation time did not show significant effect. Flocculation efficiency increased when magnesium ion concentration was 4 mM and started at pH 10 for microalgae culture with high biomass concentration and at pH 11.5 for low biomass concentration, while optimum pH for both culture was 11.75. Flocculation efficiency for microalgae with high concentration of biomass at optimum condition was 94.89% while for the low one was 89.75%.Keywords: flocculation, flocculation efficiency, magnesium ions, microalgaeABSTRAKMikroalga berpotensi sebagai bahan baku biodiesel.

Cellulase is an important enzyme for industry which can be obtained from cheap tropical agrowastes such as durian peel. West Kalimantan, in particular Pontianak city produces tons of durian peel waste during harvest season each year. This study used durian peel waste as substrates and A. niger to produce cellulase, The aim of this study is to determine the optimum incubation time in producing cellulase under solid state fermentation. Different incubation time (48, 72, 96, 120 and 144 hours) were applied for the production of cellulase. The optimum cellulase production was 120 hours of incubation, giving protein content of 0.3960% and enzyme activity of 1,069.01 ppm, respectively.

This research was to utilize solid waste of durian (durian skin) into economically valuable products. The purpose of this research was to obtain a decorative paper or art paper which can be used as a wide range of creative products such as photo frames, tissue boxes, pencil boxes and others. The research was carried out by destroying the skin of durian and other materials to form slurry and then molded and dried. Assessment of art paper quality was based on the beauty of its performance because it was display the fibers on the surface of the paper. It has been carried out analysis of gramatur, tear resistance, moisture content and ash content of the paper produced by durian skin. Paper with gramatur value, moisture content, low ash content and high tear resistance was the good quality paper. For gramatur and water content testing, a paper which was given a red ocher dye (D) is a paper that has the lowest value of gramatur and water content, each of 0.0212 g/cm2 and 7.77%. While the ash content and tear resistance testing, colored paper with mangosteen peel 17% (E) has a low ash content (0.056%) and high tear resistance (104 times fold).
