Abstract

Policies change in 1998 influenced Java sugar industrys existence because there was no more obligation to plant sugarcane. This study aims to identify (1) existing sugarcane procurement by the industry, (2) the profitability, in private as well as social prices, of sugarcane farming system as the industrys supplier, and (3) sensitivity analysis on relevant sugar dynamics.The study was conducted on five industry samples spread over Java. The primary data for profitability analysis covered 300 units originated from 185 farmers and 115 industrys plantation units in a proportional spreading.The finding exhibits three alternatives of procurement: (1) partnership with farmers based on minimum return on land, (2) partnership with farmers as the industry provides assistance, and (3) purchasing sugar from free farmers. Using data in 2002, only two samples were financially profitable,-those were east part and west part of Java, while the only region gained social profit was the east part. In spite of that, if social price of sugar using relevant foreign production costs instead of CIE Java has its comparativeadvantage. Sensitivity analysis resulted in Java will achieve financial profit if sugar price rises by 10 percent, or productivity rises by 15 percent, or tariff of 50 percent imposes.

Abstract

Pigmented rice may have a black or red color due to higher anthocyanin content in its grain. A natural antioxidant, many studies on anthocyanin have reported its positive effects on human health. This fact has spurred the development of pigmented rice as a functional food. This study aimed to compare the metabolite profiles of black and red rice. Three black rice cultivars, namely Melik, Pari Ireng, and Cempo Ireng Sleman, and two red rice cultivars, Inpari 24 and RC 204, were used. After husk removal, grain samples were ground in liquid nitrogen and dried with a freeze dryer. The dried samples were extracted using 50% MeOD4 (in a D2O phosphate buffer pH 6 containing 0.01% TSP as an internal standard). Metabolomic analysis was performed using 500 MHz NMR followed by multivariate data analysis. An orthogonal partial least squares-discriminant analysis (OPLS-DA) model ađer PCA was constructed to discriminate between the five different cultivars. The resulting OPLS-DA score plot revealed a clear separation between black rice and red rice. The metabolites that could influence the separation of red rice and black rice were valine, threonine, alanine, glutamate, galactinol, β-glucose, α-glucose, raffinose, and fumaric acid.

Abstract

White rice has become the main source of carbohydrates, but in the last few years, red and black rice are getting more popular. Red and black rice can be an alternative food for people who wish to reduce the risk of diabetics due to its low glycemic index. Pigmented rice demand in Yogyakarta is continuously increasing. However, farmers are reluctant to plant pigmented rice because of their lower yields. Value chain analysis on pigmented rice is performed to provide the condition of the business? performance for farmers who are not willing to work on pigmented rice yet. The objective of this study was to identify the main activities and to measure the performance of the value chain. The value chain performance was measured by calculating profit, marketing margin, and farmer?s share. In the business of pigmented rice nowadays, there are 5 actors involved, i.e. farmer, farmers group, association of farmers groups, distributor, and retailer. These five actors formed 5 value chains for red rice and 4 value chains for black rice. The main activities were cultivating, cropping, milling, sorting out, packing, and selling. The performance of the pigmented rice was as follows: on the red rice value chain, farmers earned the highest profit in each chain, except on the chain where the association of farmers groups was involved. The largest marketing margin was found on the farmer ? association of farmer groups ? retailer ? end-user consumer chain. On the black rice value chain, farmers earned the highest profit in each chain, except on the chain where the farmers group was involved. The largest marketing margin found on the farmer ? farmers group ? distributor ? retailer ? end-user consumer chain. For both the red and the black rice value chain, the farmer?s highest share was obtained on the farmers ? distributor ? end-user consumer chain.
