Abstract

The objectives of this study were to illustrate the structure of the soybean supply chain, to identify the performance of the soybean supply chain, and to recommend improvements in the form of managerial implications. This research used descriptive analysis method, and the analyzer used in this research was Supply Chain Operation References (SCOR). This study used primary data and secondary data. The primary data were obtained from direct observations, Focus Group Discussion (FGD), in depth interviews, and questionnaire whereas the secondary data were collected from literature study, farmer group data and agricultural statistical data from the Agriculture Department and Ministry of Agriculture. Based on the analysis of the supply chain structure, it was illustrated that there are two major parts of the supply chain structure, i.e. the short structure in which the breeder group acts as the main distributor, and the long supply chain structure in which the distribution pattern starts from the agent and dealer prior to reaching consumers. In general, the performance of the soybean supply chain in Grobogan Regency is reasonably good as it can be seen from the orders delivered to the customers and the perfect and in time order fulfillment as well as the suitability of the product with the increasing qualification standard. The order fulfillment cycle also can be adjusted with stock availability, and the supply chain flexibility can still be optimized when there is a sudden order, and supply chain costs can be covered from the sales of soybeans.Keywords: soybeans (Anguilla spp.), SCOR, supply chain, Grobogan District

Abstract

Utilization of lignocellulosic biomass from sugarcane bagasse for bioethanol production Sugarcane bagasse is one of potential lignocellulosic biomass for energy through physical, chemical or biological conversion. The material is renewable and abundantly available, especially as wastes or by-products of sugarcane industries. Of many conversion processes, lignocellulosic conversion to ethanol becomes focus of interest recently, since ethanol can be further used as biofuel to substitute gasoline for transportation. Lignocellulosic material, including sugarcane bagasse mainly consists of three components, namely cellulose, hemicellulose, and lignin. The conversion of these materials basically consists of pretreatment, cellulose hydrolysis, sugar fermentation to ethanol, and purification of ethanol. Production cost of this conversion is still high; therefore, many researches have been conducted to improve the conversion process, either pretreatment, hydrolysis, fermentation or purification, so that the cost could be reduced. This paper reviewed literatures on potential and characteristics of lignocellulosic materials, especially sugarcane bagasse, and conversion of these materials to ethanol. There is as much as 614,827 kL/year of ethanol potentially produced from sugarcane bagasse resulted from sugarcane factories in Indonesia. This amount of ethanol would have a great contribution to fulfill 1.10 million tons demand of ethanol. However, there are still some recalcitrans in production and implementation of lignocellulosic bioethanol, especially due to the unproven conversion technology of lignocellulosic biomass to ethanol and the high production cost. Therefore, government policies in supporting research and development, providing special incentives for sugarcane factories that produced ethanol from sugarcane bagasse, and giving subsidy to reduce bioethanol price, are needed.Keywords: Sugar by products, lignocellulose, conversion, ethanol

Abstract

Cassava pulp and tapioca flour are potential sources of glucose. In this work, validity of microwave irradiation for hydrolysis of carbohydrates, especially starch, present in cassava pulp and tapioca flour was estimated as a non-enzymatic saccharification technique. Suspension of cassava pulp or tapioca flour in distilled water (1g/20 mL) was subjected to microwave irradiation at temperatures of 140-240 °C with pre-heating time of 4 min and heating time of 5 min. Solubilization rate of cassava pulp increased with increasing temperature of microwave heating treatment and reached maximum (92.54%) at 220 °C, while that of tapioca flour reached almost 100% at 140 °C. Production of malto-oligomers from starch in cassava pulp and tapioca flour was clearly observed at 220 °C. The highest glucose yields from cassava pulp and tapioca flour in this experiment were 28.59 and 58.76% dry matter, respectively. Variation of pre-heating time at 230 °C did not give significant effects on glucose yield from cassava pulp. However, glucose yield from tapioca flour decreased due to increase of pre-heating time. Microwave irradiation is a promising method of hydrolysis for cassava pulp and tapioca flour due to the fast process.

Abstract

Recently, due to depletion of  fossil derived energy stock in the world, there are growing  interests in utilizing biomass sources of bioethanol. There are basically two types of biomass that are usually used or converted to ethanol, starchy and lignocellulosic biomass. The conversion of starchy and lignocellulosic materials are widely explored,  however,  there  are  still  some  drawbacks,  such  as  high  enzyme  cost  and  intensive  energy  needed. Therefore, lower cost as well as energy and time efficient process technology in biomass conversion to ethanol  is important in enhancing the use of biomass to substitute fossil fuel. Microwave heating offers some advantages to overcome these drawbacks, especially due to its quick heat transfer and its heating selectivity. In conventional heating the  heat  was  transferred  through  conduction  or  convection  process  which  took  longer  time.  Thus,  by using microwave, degradation of starchy and lignocellulosic biomass could be completed in shorter time than by using conventional heating method. The roles of microwave heating in the degradation of biomass, especially starchy and lignocellulosic biomass  and its relation to the hydrolysis and pretreatment of that particular biomass for ethanol production are reviewed and discussed.   Keywords: biomass, pretreatment, ethanol, microwave
