Abstract

Groundnut is an economically important oil crop. Main fatty acid components of the groundnut oil are oleic and linoleic acid, which are useful to human health. Forty five groundnut genotypes were grown at the Jambegede Experimental Farm, Malang, East Java during the dry season of 2009. Samples of the harvested grains were analyzed for their fatty acid contents at the Food and Technology Laboratory, Gajah Mada University, Yogyakarta in 2009 using gas chromatography. Groundnut cultivar Singa produced the highest pod yield (3.59 t/ha), followed by cultivars Talam 1 and Gajah (3.10 t/ha). Fatty acid composition among genotypes varied, ranging from 37.7 to 45.7%. Oleic and linoleic acids were the major fatty acid components, accounting for 70.8-85.4% of the total fatty acid contents. The average of oleic, linoleic, palmitic, behenic, and arachidic acid contents was each 37.7%, 41.2%, 12.5%, 3.6%, and 3.0%, respectively. Genotype MLGA 0261 contained the highest oleic acid (49.3%), while MLGA 0077 contained the highest linoleic acid (48.9%). Significant negative correlation between oleic acid content with linoleic acid (-0.59**), palmitic acid (-0.49**), and behenic acid (-0.45**) was detected. These correlations indicated that high content of oleic acid would be followed by low linoleic, palmitic, and behenic acids. Based on the fatty acid content, the groundnut genotypes were divided into three groups. Group I contained palmitic, linoleic, and behenic acids above the average. Group II contained oleic and arachidic acids below the average, and Group III contained high oleic acid and low other fatty acids. Cultivars Gajah, Tapir, Turangga, Sima, Singa, Zebra, Panter, Tuban, and Talam 1 were belong to Group I, where as cultivars Badak, Landak, Jerapah, and Kancil were in the Group II, and MLGA 0261 in Group III.

Abstract

The study was conducted at ICERI (Indonesian Cereals Research Institute), at the Laboratory of Chemical Engineering, Paulus Christen University (UKIP), and at Laboratory of Bioprocess, Department of Chemical Engeneering, Polytechnic Ujung Pandang, from March to November 2010. The aim of this study was to determine the potential ethanol production derived from juice, bagasse (sellulose), and sorghum grain (starch). Eleven sweet sorghum genotypes were tested, local varieties Selayar Hitam, Sorgum Hitam, and variety Numbu were used as checks. The results showed that yield of stem biomass, high brix sugar content, high yield of bagasse, high grain yield, and high content of glucose derived from grain were characters that could be used as criteria for selection of sorghum genotypes producing high ethanol per unit area. These characters were correlated with the ethanol production per unit area. Genotypes 1521A, 15011A, and Watar Hammu Putih were prospective sweet sorghum for the ethanol production. These genotypes were supported by high yield of stem biomass per unit area, high brix sugar content, and high grain yield than check varieties, except for Watar Hammu Putih. Although all of the three raw materials had the potential use for bioethanol production, stem juice and bagasse were more suitable to be used than the grain, since it would not compete with the use of grain for food.
