Abstract

Flooding and overflowing on horticultural plant especially for tomato plants cause failure of vegetative and generative growth.The extent to which tomato plants tolerance if grown in andosol soil to overflowing and flooding need to be studied. This research was aimed to examine the Effect of Overflowing length on the water quality and soil physical properties of andosol together with tomatoe plant growth. The result of the research showed that evapotranspiration at beginning of growth of 15 days since plant (dsp) was 1,79 mm/day, on active growth (16-45 dsp) was 3,45 mm/day, on maximum growth (46-75 dsp) was 3,45 mm/day and the end of growth (>75 dsp) was 2,41 mm/day. Water quality that unfavorable effect towards the growth of tomato plants for 2 days in overflowed conditions and overflowed until the plants death was dissolved oxygen. Dissolved oxygen for 2 days in overflowed conditions was 1,98 ppm and for overflowed conditions until the plants death was 1,68 ppm.Soil Physical properties that unfavorable effect towards the growth of tomato plants for all conditions was soil temprature. Soil temprature for 2 days in overflowed conditions was 27,83oC, for overflowed conditions until the plants death was 28,25oC and for spacey capacity conditions was 27,85oC. For 2 days in overflowed conditions the soil salinity was over the restriction limit which was 5,8 mS/cm. Blossom production of tomato plant on spacey capacity conditions was 27 blossom/plant, for 2 days in overflowed conditions was 17 blossom/plant and for overflowed conditions until the plants death has not blossom. Key word : overflowing, tomato plants, water quality, soil physical properties

Abstract

.Analysis of these wetland cultivating was aimed to obtain information on wetland cultivating until ready for planting using a two-wheeltractor, calculating the effective field capacity, field efficiency, and fuel consumption for cultivation until the condition of the land ready for planting with working speed variations. This study uses a factorial randomized block design with two factors.The first factor was the treatment variation until ready for planting and the second factor was the variation of speed (1m/s, 1,2m/s, and 1,4m/s). Parameters measured were land cultivating capacity, fuel consumption, efficiency of tractors, and economic analysis. Results of this study showed that the difference in treatment until ready for planting had a significant effect on effective field capacity, efficiency, and fuel consumption. The highest Effective Field Capacity (EFC) of any cultivating until the rice fields ready for planting was at a speed of 1.4m/s. The highest processing efficiency was obtained at a speed of 1.4m/s. The greatest fuel consumption obtained in the second cultivation pattern. Keywords: tractors, paddy fields,cultivatinguntilready to plant.

Abstract

Information System of Agricultural Land ( Rice) in Manduamas Sub District area was still done manually, so the storage, processing and delivery of information to be ineffective and inefficient. In the information management most the result were done by human role and took a relatively longer time. Moreover, the information seekers-and decision-makers also had difficulty in obtaining the data they need. Therefore, it is necessary to further develop of the information system. Web-based information system is considered to be a solution in order to access information faster, systematicaly and easy to use. For that a web-based information systems in the management of imformation system of agricultural land ( rice) in Manduamas sub district was designed. Agricultural land network information system was designed using PHP programming language, MySQL database and the method of system development life cycle (SDLC). The result was adynamic website that displays information and could interact with the user and was user friendly where the model user interface of the web was made to facilitate the user to use system properly. Keywords: Agricultural land, information system, Manduamas Sub district, rice, web.

Abstract

On mechanical coffee roasters, roasting temperature needs to be considered. The temperature determines the quality of the roasting product. This study is testing the temperature at various levels of coffee roasters rotary tool on the yield and quality of coffee. The study was conducted at the Laboratory of Agricultural Engineering USU College of Agriculture in January to April 2013 using a non-factorial completely randomized design at 70 ⁰ C, 75 ⁰ C, 80 ⁰ C, 85 ⁰ C and 90 ⁰ C. Parameters measured were yield, processing capacity and water content. The results showed that the test temperature had highly significant effect on yield,had highly significant to the processing capacity, and had not significant affected the water content. The best treatment of this research is the treatment T3 (80⁰C) which produced 81.2% yield, processing capacity of 3,252 kg / hour, and the water content of 5.948% Keywords: Coffee roaster, Coffee quality, Temperature test

Abstract

Seepage is one of the causes of lost of water in irrigation channel. It is difficult to measure the seepage directly on the field. Therefore there should be a model or equation to determine the channel seepage that is the first stage through laboratory scale. This research was done to analyze the seepage coefficient of trapezoidal cross-section irrigation channel on Latosol soil through laboratory scale. The water balance component which was measured were evaporation, percolation and seepage through channel wall. The research showed that the coefficient of seepage was about 3732,48 to 5339,52 mm/day. The evaporation  value was 1,33 mm/day and channel percolation was 376,41mm/day. Key Word : coefficient of seepage, irrigation channel, trapezoidal cross-section, Latosol soil, laboratory scale.
