Abstract

Cassava flour is a modified cassava flour which is similar to cassava flour, but the manufacturing process has been done with improvements and refinements. The quality of cassava flour produced is determined by the processing process of the type / variety of cassava used as raw material. This study aims to determine the level of consumer preference for wet and dry preparations, yield, and the break-even price of cassava flour from several varieties of cassava. The study used 2 varieties of cassava (UJ 5 and Klenteng) and 2 immersion treatments (addition of starter Bimo-CF and without addition of starter Bimo-CF), to determine differences in the resulting processed products. The results of the addition of the Bimo-CF starter to cassava flour, in wet processed (sponge cake) and dry processed (stick) products were preferred by consumers compared to those without the addition of Bimo-CF starter. The addition of starter Bimo-CF resulted in cassava flour with a higher yield and lower break-even point compared to without the addition of Bimo-CF starter, both on varieties UJ 5 and Klenteng.

Abstract

Coffee is a leading export commodity in Lampung Province. The main problem in coffee farming is low productivity and low farmers income. Coffee plant productivity has tended to decline in the last 3 years. Coffee productivity in West Lampung Regency was recorded at 1.205 kg/ha in 2016, down to 961 kg/ha in 2018, and coffee productivity in Tanggamus Regency in 580 kg/ha in 2016 down to 457 kg/ha in 2018. The use of organic fertilizer relatively low at 33,3% in West Lampung Regency and 30,2% in Tanggamus Regency. Polatanam which is commonly done by coffee farmers in Lampung Province is mixed cropping of 84.12% and coffee monoculture only 15,88%. Factors that influence of coffee production in Lampung were land area, the use of organic fertilizer, the use of top-grafted seedlings, farmers income, and age of coffee plants.

Abstract

Soybean is one of the leguminous plants and is the main source of protein and vegetable oil in the world. Soybean is the most important strategic main food crop after rice and corn. Caused of their high protein and fat content, soybean seeds have fast decreased quality during storage, both for consumption material and as a source of seeds. This study aims to determine changes in physical and chemical quality of several soybean varieties during storage. This research was conducted from February to August 2016 in the Agricultural Science Park (TSP) Natar. The study was conducted in a Randomized Block Design (RBD) with three replications. This study uses 4 soybean varieties, namely: Grobogan, Burangrang, Anjasmoro, and Argomulyo; packaged using polyethylene plastic bags (PE) 0.8 mm. Observation parameters included physical quality (split grains, broken grains, other colored grains, wrinkled grains, and impurities), hardness and chemical quality (moisture content, ash content, protein content, fat content, crude fiber content, and carbohydrate content). The observations showed that: Anjasmoro variety has the best physical quality (Quality I) compared to other varieties, both before storage (0 months), and after storage (6 months); There was increased water content, protein content, ash content, and crude fiber content, but a decrease in carbohydrate content in soybean seeds after storage for 6 months, while the ash content did not change significantly;There was increased the level of hardness of soybean seeds during storage for 4 soybean varieties that were used around 3,68% - 8,33%.
