Abstract

Soybean plants were flooded for a long time will inhibit the growth and yield of soybean. For that, there should be proper drainage, in order to cope with flooding due to decreased plant productivity. This study aimed to assess the effect of long inundation on the growth of soybean plants using Andosol soil. Measure variable is water quality, physical properties soil and soybean production. The results indicate that water quality parameters waterlogged conditions 3 days whereas the dissolved oxygen, in the affect the physical properties of soil is the pH of the soil, with soybean production (2 plants / pot) 96 pods. On the waterlogged conditions until wilted/dead water quality parameters  affect the dissolved oxygen and pH of the water, in the affect the physical properties of soil is the pH of the soil, with soybean production 36 pods. On the condition of field capacity water quality parameters and physical properties of soil in accordance with the terms optimal growth of soybean plants, with soybean production 241 pods. Keywords: water quality, soil physical properties of Andosol, the growth of soybean plants

Abstract

In the distribution of irrigation water through a soil tertiary canal, there can be a great loss of water, sedimentation and canal scoured if not well designed. This research was aimed to review, to calculate the waterloss and efficiency as well as to designing a good canal dimensions of tertiary canals to prevent scour and sedimentation at 2 tertiary canals in the Sei Beras Sekata village Sei Krio Sunggal, Deli Serdang district. The results showed that sedimentation occurred in both tertiary canals, so that redesign of the dimensions on the both canals was needed. Efficiency at the same distance (30m) in the canal 1 was 79,42 % and canal 2 was 91,72 %. The best tertiary canal dimensions for canal 1 was the combination 0,02% slope, the channel width (B) was 0,62 m and the depth of water (D) was 0,31 m and  for canal 2 was the combination 0,02% slope, the canal width (B) was 0,58 m and the depth of water (D) was 0,29 m. Key Word: Tertiary Canal, Waterloss, Conveyance Efficiency and Canal Dimensions

Abstract

Mechanical roaster has multi functional for bean commodities. The aim of study was to test mechanical coffee roaster rotary type with soybean commodity. This research was conducted at the Laboratory of Agricultural Engineering, Faculty of Agriculture, University of North Sumatra in November until December 2012 by study of literature, experiment, observation, and testing of the equipment. Parameters observed were effective capacity, moisture content, and the economic analysis. The results showed that the effective capacity of a mechanical soybean roaster  type rotary  was 5.590 kg/h, the highest water content was 7.07% and the lowest was 5.70%, while from the economic analysis, the BEP was 3.885,42 kg, NPV 16% and 20% were Rp. 13. 758.853,97 and    Rp. 12.086.672,76, respectively and the IRR was 52,91%. Keywords: mechanical roasters, soybean, water content, effective capacity.

Abstract

Palm oil mill solid waste resulting from CPO production process is channeled into pond waste (Cooling Pond I). It is usually thrown to the ground so that it can contaminate the environment. This study was aim to utilize the oil palm waste as briquettes. Briquettes is one of the alternative to replace oil. Research was done by completely randomized factorial design with 2 factors i.e : density of air line (0,4, 0,8, and 1,2 cm) and Height of used cooking oil (2, 2,5, and 3 cm). Parameters observed were heating time, oil volume, and sootness. The results showed that the density of air line had a highly significant effect on the heating time, volume of oil and had no effect on the sootnes. Height of used cooking oil had a significant effect on sootness and had no effect on the heating time and volume of oil. The best treatment combination was L1T2 (0,4 centimeters density of air line and 2,5 centimeters Height of used cooking oil) with equipment heatimg time of 43,90 minute  and 1,79 gr sootness. Key words: Briquettes, density of air line, Height of used cooking oil centration, Oil palm solid waste.
