Abstract

This research was conducted to find the effect of steaming and frying time on the quality of chpis from durian seed. The research had been performed using factorial completely randomized design with two factors, i.e the steaming time (W): (10, 15, 20 and 25 minutes), and frying time (P) : (1, 2, 3 and 4 minutes). Parameters analyzed were moisture content, fat content, yield and organoleptic values (colour,taste and flavor, and crispiness).The results showed that the steaming time had highly significant effect on moisture content, fat content, yield, colour, taste and flavor, and crispiness. Frying time also had highly significant effect on moisture content, fat content, yield, colour, taste and flavor, and crispiness. The interaction of the two factors had highly significant effect on moisture content, fat content, and yield .The  25 minutes of steaming and 4 minutes of frying  gave the best quality of chips from durian seed. Keywords : Chips from durian seed, steaming time and frying time.

Abstract

The research was perfomed to get the ratio of germination soybean and jackfruit’s seed and fermentation agent concentration in a processing of tempeh. The research had been performed using factorial completely randomized design with two factor i.e : the ratio of germination soybean and jackfruit’s seed (K) : (90:10; 80:20; 70:30; 60:40) and concentration of fermentation agent (R) : (0,2; 0,4; 0,6; 0,8%). Parameters analysed were protein content, fat content, mineral content, water content, and organoleptic values (flavour, taste, and texture). The research showed that ratio of germination soybean and jackfruit’s seed had highly significant effect on protein content, mineral content, water content, and organoleptic values (flavour, taste), and significant effect on organoleptic texture, no significant effect on fat content. The concentration of fermentation agent had highly effect on protein content, fat content, mineral content, water content, and organoleptic values (flavour, taste, texture). The interaction of ratio of germination soybean and jackfruit’s seed and concentration of fermentation agent had highly significant effect on protein content and had no significant effect on fat content, mineral content, water content, and organoleptic values (flavour, taste, texture). The ratio of germination soybean and jackfruit’s seed at 90:10 and 0,8% concentration of fermentation agent produced the best quality of tempeh.

Abstract

Crop factor (C) is a factor that is easier to modify in an effort to reduce erosion. This study was aim to determine the value of crop factor of corn and cassava during July to October 2012 using USLE prediction and methods of small plots. In addition, this study was also aim to quantify the allowable erosion rate (T) and Erosion Hazard Level (TBE). Parameters measured were effective soil depth, soil permeability, levels of C-organic soil, soil texture, soil structure, and rainfall. The results showed that the value of the cassava crop factor using rainfall research data for 4 months and 12 years data were 0.68 and 0.69 respectively, and the value of the corn crop factor using rainfall research data for 4 months and 12 years data were 0.58 and 0.59 respectively. The amount of allowable erosion rate is 17.17 ton (ha.year)-1. While Erosion Hazard Rate (TBE) corn and cassava land were 0.020 and 0.024 respectively, which included in the low category. Key words: Erosion, Ultisol, Crop Factor, Siborongborong

Abstract

Cultivation of crops on sloping land is  vulnerable to erosion if no soil and water conservation measures applied. This study was aim to quantify the erosion, determining the tolerable rate of erosion, and the erosion rate (TBE) in the Ultisol soil on slopes: 9%, 19%, and 32% plantedwith  peanuts, using small plots and USLE predictions on July-October 2012 in the District Siborongborong. The results showed that the amount of erosion that occurs for USLE prediction method based on 12 years of rainfall data for the slopes of 9%, 19%, 32%, were 20.91, 69.43, and 166.47 tons/ha.year respectively, with moderate to very high TBE category. USLE prediction method based on rainfall data for four months of study with 9%, 19%, 32% slopes, were 0.4, 1.2,and 2.9 ton/ha.year respectively with low TBE category. Small methods plots for slopes of 9% 19%, 32%, were 12.36, 12.54, and 0.63 tons/ha year respectively with low TBE category. The magnitude of the tolerable rate of erosion at 17:17 tonnes/ha.year (17.17 mm/ha.year). Key words: Erosion, Ultisol land, Peanut Plant, Siborongborong

Abstract

Infiltration is a very important component in soil conservation. Because as it coralation with rain intensity, run off, and erosion. The aim of this research was to know  the infiltration rate in some type of lands i.e chili field, coffee field, and bush at Sempajaya Kecamatan Berastagi Kabupaten Karo using Philips equation model. Parameters observed were moisture content, soil texture, bulk density, particle density, porosity, organic matter and cumulative infiltration was used. Double ring infiltrometer that pressed into the soil, and filled with water was used. The decreased of water was observed with interval of  0, 5, 10, 20, 30, 45, 60, 120, 180, 240 minutes. The results showed that the highest infiltration rate was found in bush, followed by chili field, and the smallest was found in coffee field. The biggest influence on the  infiltration rate was organic matter. Key words: Infiltration rate, chili field, coffee field, bush, Sempajaya

Abstract

This research was aimed to test the effect of different mesh sizes on the quality of coffee beans in the multifucer grinder using roasted arabica and robusta coffee beans. The parameters measured were the effective capacity of the equipment, the percentage of material that passed the sieve, coffee powder moisture content, percentage of soluble coffee powder in water and organoleptic tests. The results showed that the best effective capacity was 35.56 kg/hour for the treatment of robusta coffee with 250 mesh sieve, the percentage of material that passed the sieved was 93.33% for Arabica coffee at 150 mesh sieve. The best coffee powder water content was 2.43% for Arabica coffee at treatment with 250 mesh sieve. The best percentage of soluble coffee powder was 33% at 250 mesh sieve. The best aroma was 3.9, which means that the aroma was very typical for treatment of 250 mesh sieve. The best taste was 3.46, which means the taste was typical for Arabica coffee at 250 mesh sieve. The quality of coffee powder produced from the grinding was in compliance with the quality standards of Indonesia. Key words: multifucer, sieve, mesh, robusta coffee, arabica coffee.

Abstract

Sloping land has a high erosion potential if converted to agricultural land without conservation measures. This study was aimed to measure erosion, determine tolerable erosion rate and Erosion Hazard Level (TBE) the Ultisol soil erosion using intercropping crop with peanuts and corn with slope of 9%, 19%, and 31% in July-October 2012 in the District Siborongborong using small plots and USLE predictions. The results showed that the amount of erosion using small plots for slope 9%, 19%, and 31% were 0,3 tons (ha.years)-1, 0.52 tons (ha.years)-1, and 0, 68 tons (ha.years)-1 respectively with low Erosion Hasard Level (TBE) category. USLE predictions based on 12 years of rainfall data for the slope of 9%, 19%, and 31% were 40.78 tons (ha.years)-1, 130.08 tons (ha.years)-1, and 312.78 tons (ha.years)-1 respectively with Erosion Hazard Level (TBE) category of moderate to very high. Predictions based on the USLE 4 months rainfall data for slope of 9%, 19%, and 31% were 1,02 tons (ha.years)-1, 3,28 tons (ha.years)-1, and 7,89 tons (ha.years)-1 respectively with low Erosion Hazard Level (TBE) category. The amount of tolerable erosion rate is 17,17 tons (ha.years)-1. Key words: Erosion, Ultisol Soil, Mixed Crops, Siborongborong
