Abstract

This research studied the moisture sorption behavior of jatropha seeds by developing a model that correlates the equilibrium moisture (EMC) and Free Fatty Acids (FFA) contents as a function of water activity and EMC, respectively. Two sets of sorption-isotherm experiments were performed to describe the relationship of EMC and FFA contents with water activity, both for fresh and dried seeds of Banten and Lampung varieties. The seeds are conditioned in a series of vessel with saturated salts at certain water activity. The EMC were increased following an increase in water activity in either desorption or adsorption. The hysteresis effect is more pronounced at Banten variety than Lampung one. The FFA content of fresh seeds was increased with an increase in water activity, while the FFA content of dried seeds is relatively constant. The moisture sorption behavior of jatropha seeds reveals that like most product, it exhibits the sigmoid pattern. The BET, GAB, Harkins-Jura, Halsey and Oswin models are recommended to be adequate in predicting the amount of moisture adsorbed or desorbed at known humidity. The relationship between EMC and FFA contents shows that the polynomial equation is the best for fresh seeds, and constant equation for dried seeds.Keyword: moisture sorption; jatropha seeds; water activity; equilibrium moisture content;

Abstract

 The removal characteristics of hydrogen sulfide (H2S) by organic (compost) and inorganic (granular activated carbon) carriers were studied at a laboratory scale. The compost, activated carbon and mix of them with the ratio of 1:1 were evaluated as packing materials of packed tower deodorization apparatus (biofilter) from the view points of biological removal characteristics of H2S and some physical properties. The removal rate of H2S by compost, activated carbon and mix of them (1:1) in non-biological treatment were 0.22, 0.37, and 0.88 g-S.kg-dr-material-1 respectively. However, the maximum removal rates of H2S by biological treatment were 11.85, 14.66, and 20.49 g-S. kg dry-material-1 respectively. The removal rate of H2S from all packing materials after inoculated with mixed culture of Thiobacillus sp. was increased due to biological oxidation by Thiobacillus sp. The mixed of compost and activated carbon showed the best result to remove H2S from contaminated air. Keywords : Biofilter, H2S, Thiobacillus sp., compost, activated carbon.

Abstract

 Pure plant oil could be obtained from various seeds, such as rubber seed. Rubber seed oil could be converted into biokerosene. The objective of this research was to explore the potency of biokerosene from rubber plantation both smallholder and goverment owned estate (PT. Perkebunan Nusantara). In addition, the ability of rubber seed biokerosene to ignite kerosene stove at households was also evaluated. The experimental design was Block Randomized Factorial in order to evaluate the yield from rubber seed extraction. We also set a Completely Randomized Factorial experiment to learn the influence of peeling and sun drying to the density, viscosity, and FFA (Free Fatty Acid), of extracted oil. Paired-t test was used for analyzing whether the characteristics of crude oil differed from those of biokerosene. The results showed that the oil yield was affected by peeling factor and not by sun-drying. The result showed that peeled rubber seeds yield was higher than that of intact seeds. Yield of crude oil and biokerosene from state owned as well as one from maintained plantation was higher yield than that from smallholder or un-maintained plantation. Factors of peeling and sun-drying did not affect the values of FFA, density and viscosity. Biokerosene added to kerosene could extend the duration of flame. The best mix proportion was 20% biokerosene and 80% kerosene which was further tested with the community on kerosene stoves. Keywords: biokerosene, kerosene stove, oil extraction, rubber seed.

Abstract

 The objective of this research was to develop an intelligent decision support system for optimization of horticulture supply chain model using genetic algorithms. The case study was conducted at PT. Saung Mirwan, Megamendung-Bogor, a major producer of packed fresh vegetable and fresh-cut vegetable. The output of this research is an Intelligent Decision Support System of Supply Chain Management for Horticulture Agro industry (IDSS-SCM). IDSS-SCM consists of eight models: Products Demand Forecast, Vegetables Supply Forecast, Planting Schedule, Aggregate Planning, Material Requirements Planning I, Material Requirements Planning II, Inventory Management, and Transportation Route. Based on the most recent data collected, IDSS-SCM predicts that product demand will increase and it then gives optimum recommendations to the user such as plant schedule, material requirements planning, inventory, human resource allocation, and distribution route to fulfil the demand. The unique feature of this research was that a genetic algorithm (GA) with Partially Matched Crossover (PMX) operator was used to find the shortest distribution route as well as to optimize human resource allocation problem. The experiment results indicate that the GA developed in this research can solve a complex agroindustrial supply chain design problem faster and more efficiently. Keywords: intelligent decision support system, genetic algorithms, supply chain management, agroindustry, partially matched crossover.

Abstract

 Banana trees are rich of cellulose and a potential source for producing glucose. The aim of the research was to develop a mathematic model of banana tree fiber hydrolysis by using sulfite acid as catalyst. The concentratios of the acid catalyst were 0.25 M, 0.5 M, and 1M at temperature of 85 oC and 100 oC. The concentration of acid catalyst and the reaction temperature were varied to determine the activation energy that might be affected by the addition of acid catalyst. The sugar concentration was measured as an hydrolysis parameter. The concentration of reducing sugar produced during the hydrolysis process was also measured to develop the mathematical model of hydrolysis process. The values of determination coefficient (r2) from mathematical model of kinetic reaction were more than 0.8. The kinetic model was valid for concentration range from 0.25 M to 1.5 M. Keywords: mathematical model, determination coefficient, hydrolysis, banana trees, liquid acid catalyst

Abstract

 Cassava, locally known as ubi kayu, singkong or ketela pohon, has huge potency due to: (i) can be grown in almost all climate conditions, (ii) drough resistence, (iii) raw material for many uses vary from food, feed to energy, and (iv) technically well known by community. However, there is no strong cassava based processing industry (tapioca, cassava flour, glucose syrup, and ethanol) grow with good business insight. This review sees the gap comprehensively between the capacity to produce and availability of raw material (fresh cassava), and high potency of uses and increasingly down stream product demand. This paper ends with recommendations on how to bridge upstream potency and down stream demand through the development of cassava based industry. Special discussion on Cassava Research Center is provided. Keywords:   Cassava Research Center, development, food security, biofuel
