Analysis of Taste Quality of Organic Arabica Coffee in Several Altitudes and Processing Techniques in Gayo HighlandsAbstract. In general several varieties of Arabica are cultivated at the same altitude, which cause loss of their unique flavor of Arabica Gayo Highlands. This research was aimed to find out of superior varieties of Arabica coffee with a unique flavor score at a certain altitude and specific processing technique in the Gayo Highlands. There were five varieties of Arabica coffee observed. (Borbor, Bergendal, Ateng Super, Tim-Tim and Lini-S), in four altitudes: (1. 1.000 m; 2. 1.000 -1.200 m; 3. 1.200 1.400 m; and 4. 1.400 m above sea level). A survey method with descriptive analysis was used, based on altitude and land use maps on 20 observation sites. Ideal altitude of varieties were identified as nell as soil and barriers samples were analyzed. Arabica coffee varieties was determined by cluster analysis, correlations, followed by multiple regression. Evaluation scores of flavor varieties of Arabica coffee and altitude showed that Borbor variety was suitable at altitude 1.400 above sea level, Tim-Tim 1.200 m, and Ateng super at altitude 1.200 -1.400 m above sea level. Processing method of organic Arabica coffee which produced high flavor quality (taste) was a semi wash processing. Result of multiple regression analysis showed a very close relationship between land characteristics and score flavor criteria, R2 was 0.894. Determinants of the best and unique flavor is the altitude, climate and processing of organic Arabica coffee beansAbstrak.

Status of Arbuscular Mycorrhizal Fungi in Different Farming Systems and Age of Oil PalmABSTRACT. A survey was conducted to determine the Arbuscular Mycorrhiza Fungi (AMF) spore population in rhizosphere soils and its root colonization of oil palm belonging to four age class (2-3months, 2 years, 7 years, and 10 years) at PTPN I Estate plantation and smallholder farmer plantation in Cot Girek Aceh Utara. The methods used were direct isolation. The result showed that there were 14 species of AMF belongs to genus Glomus identified according to spore morphology, eight species at PTPN I and six species at smallholder oil palm plantation. AMF spore density at PTPN I and smallholder oil palm was 17.35 and 17.80 spore per 50g soil, respectively. Oil palm at 7 years old resulted in better AMF population, i.e. 53,7 spore per 50 g Soil. AMF colonization at oil palm rhizospere in both farming systems were low, i.e. 5.4% (PTPN I) and 2.9% (smallholder). Farming system and age of oil palm influenced the AMF population and root colonization, Spore density did not positively correlate with root colonization at different farming systems and age of oil palm.

Abstract

The purposes of using CBS in this research is to improve the physical properties and quality of appereance and structure stability of chocolate bar. Based on chemical composition, CBS and Cocoa butter have different profile, but they have similar physical properties due to high lauric acid content. The advantage of lauric acid is to affect shinny appreance of chocolate surface, and also soapy taste that closely related to rancidity reduction. Virgin Coconut Oil (VCO) is one of lauric fat that easily found in Aceh. In this research, chocolate bar is formulated comprising various concentration of CBS (0,1,2,3,4,5%) with respect to cocoa butter, and cocoa mass composition (200 g and 300 g). It was found that melting point was affected by CBS concentration. The higher CBS concentration, the lower melting point of chocolate bar. An increase in VCO concentration reduced significantly the melting point of chocolate bar. Melting point was comparable to other chocolate bar commercial (29-32oC). The unblooming, snap, best texture and better taste was observed for the chocolate bar containing 4-5% of VCO concentration and 27,5% of cocoa mass
