Orange (Citrus nobilis var. microcarpa) is the main commodities in Pontianak. Production of essential oils from orange peel wastes and its use for soap aromatherapy substance could improve its economic value. This study is aimed to produce the essential oils from orange peel wastes with the highest limonene content by distillation. Its application for aromatherapy soap substance also evaluated. Distillation of essential oils from orange peels was performed at 1000C and 1100C for 4, 5, 6 and 7 hours. The results showed that at 1000C for 7 hours produced the highest limonene content, reach 97.69%. The essential oils color was pale yellow, specific gravity 0.84, refractive index 1.47, solubility in 90% ethanol 1:1 (transparent), acid value 0.143% and ester number 5.37. The aromatherapy soap produced with addition of 3.6% of limonene oils is in accordance with SNI 06-3532-1994 except for water content parameter.

Dextrin is a modified starch that widely used in food and pharmaceutical industries. One of the starch source that could be used for dextrin production is sweet potatoes that widely cultivated in Pontianak. The aims of this study is to produce dextrins enzymatically using different types of sweet potatoes that available in Pontianak. Dextrin production optimization performed on 0.1%, 0.2%, and 0.3% of alpha amylase concentrations and liquification at 95°C for 1, 1.5 and 2 hours. Three varieties of sweet potatoes used: white, yellow, and purple. The results showed that the highest dextrin production is at 0.3% concentration with 2 hours of liquification. The characteristics of the dextrose produced are: fairly soluble in water, dextrose content range 4.14%â4.41%, water content was 10.5% â11.0%, yield range 7%â12%, and 80 mesh filter pass between 91â95%. Dextrins production has met SNI 01-2593-1992 standard dextrin for the food industry.

Coastal areas of West Kalimantan province are rich with seaweed. To increase its economic value, seaweed could be used as primary materials for organic fertilizer production. This research was conducted to find the optimum combination of seaweeds used for organic fertilizer production using Brassica rapa as test plant on alluvial soils. Most dominant seaweeds found were used for biofertilizer production. Three types of seaweeds used were brown (Phaeophyceae), red (Rhodophyceae), and green (Chlorophyceae). Formulations used were 1:1:1, 1:1:2, 1:2:1, and 2:1:1. The formulation that met the biofertilizer quality conformance was applied on alluvial soils using Brassica rapa as a test plant. Result showed that 2:1:1 and 1:2:1 ratio of brown-red-green seaweed is the best formulation based on most growth parameters observed on Brassica rapa.

Clay from West Kalimantan is still used as a raw material in the ceramic industry and it doesnât have spesific processes for the manufacture of other products. The objective of this study is to determine the effect of organoclay filler on the physical properties of tensile strength clay nanocomposite food packaging applications. The step for clay nanocomposite were produced by purification, milling, organoclay, clay nanocomposite. Clay nanocomposite were characterized by analysis cation exchange capacities (CEC), X-ray diffraction (XRD), particle size analysis (PSA), scanning electron microscopy (SEM), tensile strength test and elongation at break. The purified with hydrochloric acid can increase the value of CEC and remove of the impurities. High energy milling (HEM) technique are with a time of 2 hours gained 225.3 nm sized nanoparticles as raw material organoclay. The addition of 1% organoclay filler increases the tensile strength of nanocomposite clay, according grade 2 and is suitable for second packaging or not directly contact to food.

Soybean (Glycine max) has high levels of protein. Furthermore, it also contains raffinose and stachyose, which in high amounts can lead to flatulence. It is known that Rhizopus oryzae could reduce the levels of stachyose and raffinose in soybean flour processing. Lactobacillus plantarum also could reduce stachyose levels on the processing of yoghurt from soybean. Therefore the aim of this study was to determine the reduction of raffinose and stachyose on soybean fermentation using R. oryzae and L. plantarum isolates. The study was conducted by using combination of R. oryzae and L. plantarum isolates in soybean fermentation process in different length of time. The levels of raffinose and stachyose on fermented soybean products then tested. The results of this study showed that fermentation using R. oryzae single isolates for 2 days (R2L0) can produce soybean flour with low levels of raffinose and stachyose. The products also have good color and smell.
