Abstract

Water balance model is stacked to predict soil moisture storage in pine forest. The balance is the appropriate between  the coming rainfall and the going water from pine forest. Water balance model consists of rainfall, throughfall, stemflow, interception, actual evapotranspiration, and run off. The results of research showed that daily rainfall was 16,326 mm/day and annual rainfall was 2309 mm/year. Actual evapotranspiration was 2,546 mm/day. Soil moisture storage found during 4 months the research was 385,450 mm, therefore it can be concluded that the research region was suitable for growing of pine forest.

Abstract

The aim of this research was to know the infiltration rate and matrix potential in some land uses; i.e. field, rubber field, and bush at Desa Tanjung Putus Kecamatan Padang Tualang Kabupaten Langkat using Philips equation model. Parameters that perceived were moisture content, soil texture, bulk density, particle density, porosity, and organic matter. This research used double ring infiltrometer and observed for 240 minutes. The results showed that the biggest infiltration rate was found in rubber field , and bush ; the smallest was found in field . The matrix potential in that lands were become smaller by the increasing of soil moisture.

Abstract

This research is about fruit picker tool on different type of fruit trees. This research was conducted to test the fruit picker tool on various type of fruit trees i.e melinjo, tamarind and rambutan to determine the effective capacity of the tool, the percentage of defects and field capacity of the tool. The research was conducted in Tridharma, A. H. Nasution and Bunga Mawar Roads from February to August 2012 using non-factorial completely randomized design with melinjo, tamarind and rambutan trees. The parameters measured were the effective capacity of the tool, the percentage of defect and tool field capacity tool. The results Showed various types of fruit trees had highly significant effect on the effective capacity of the tool and the percentage of defect had no significant effect on the capacity of the field. The best result was on rambutan fruit i.e 30.54 kg h-1 with the percentage of defects of 7.3%.

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.

Agricultural cultivation, particularly food crops grown on sloping land without conservation  water and soil measures have a high erosion potential. This study was aimed to measure the erosion by determining the rate of allowable erosion  and erosion hazard level on Ultisol soil using Sweet potato intercropping with plant with slope of 9%, 21%  and 32 % that small plots and USLE methods in July-October 2012 in the Siborongborong District. The results showed the amount of erosion  using small plots for slope of  9 %, 21 % and 32 % were respectively of 0.26 tons ha-1 year-1, 0,40 tons ha-1 year-1 and 0,54 tons ha-1 year-1 respectively with low erosion hazard level category. USLE method based on 12 years of rainfall data for the slope of 9 %, 21 % and 32 %, were 42,49 tons ha-1 year-1 , 165,31 tons ha-1 year-1 and 351,35 tons ha-1 year-1 respectively with moderate to very high erosion hazard level category. USLE method based on the rainfall data 4 months  the study period for slope of 9 %, 21%, and 32 % respectively by 0,75 tons ha-1 year-1 , 2,90 tons ha-1 year-1 , and 6,09 of tons/(ha. year) with low Erosion Hazard Level category and the magnitude of the erosion rate allowed was 17.17 tons ha-1 year-1 or equal to 17,17 mm year-1.

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.

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.

Abstract

The aim of this study was to quantify and to compare the modulus values ​​of wetland ricefield drainage in the village of Sei Beras Sekata. Drainage modulus value is used as a reference to throw out water from the wetland ricefield. Drainage modulus values ​was ​calculated by three methods i.e plotting maximum daily rainfall, daily inundation simulations with a daily water balance in the mapped fields, and using the formula of the Department of Public Works. It was found from the research, that the drainage modulus values on daily maximum rainfall plotting methods was 29 mm day-1, the daily inundation simulation methods with high daily water balance mapped fields was 40.3 mm day-1, and formula of the Department of Public Works was 61,2 mm day-1. Key words: drainage modulus, wetland ricefield, Sei Beras Sekata
