Abstract

Palm frond cutting is still done manually, where the operator has limitations in cutting the frond. He must be really experienced and have high levels of accuracy and the work capacity is relatively limited. Therefore a mechanical cutting equipment was made. This study was conducted in May to September 2013 in the Laboratory of Agricultural Engineering, Faculty of Agriculture, University of North Sumatra, Medan, with a literature study, making and test the equipment and observation of parameters. The parameters measured were the equipment capacity, economic analysis, break-even point, the internal rate of return, and net present value. The results demonstrated that device capacity was 142.78 frond / h, economic analysis was Rp 55.873 / frond, break event was 71577.091 point / year, the internal rate of return was 40.2547 % and the equipment was deserved to be made. Keywords : agricultural equipment and machinery, cutter, oil palm frond.

Abstract

Milling is done to powder food with a certain level of refinement to be more easily processed into other products. This study was conducted to test the capacity of the equipment using several commodities in multifucer grinder. Sorghum, soybeans, and rice were commodities to be tested to determine the effective capacity,the percentage of material not accommodated, and efficiency of the equipment. The results showed that the effective tool capacity was 19.48k/h for sorghum, 12.22k/h for soybean and 24.35 kg/h for rice. Percentage of material that was not accommodated was 7.33% for sorghum, 6.66% for soybean and 4,16% for rice. Appliance efficiency percentage was 92.66% for sorghum, 93.33% for soybean and 95.83% for rice. Keywords: Multifucer, Sorghum, Soybeans, Rice.

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

Bagasse is a byproduct of extraction (squeezing) of sugar cane. A single sugar mill can produces around 35-40% (weight) of bagasse from sugar cane milled. Bagasse which is a sugar cane mill waste can be processed into a fiber rope. Fiber rope can be made from many kind of tree bark, it makes the utilization of bagasse for a fiber rope is possible. The research was aimed to make a fiber rope from bagasse and to test the endurance of sugar cane fiber rope toward a tensile test.Results of the research indicated that each substance tested with the same weight produced different string diameter. Average value of examinatied 8 g streng had diameter of 5,83 mm, length of 58,3 mm, elongation of 22,66 mm, maximum loaded of 283,33 N, cross section of 2,489 x 10-5 m2, elongation at break of tensile strength of 105,6 x 105 N m-2, strain of 0,39, elasticity of 303,9 x 105 N m-2 and flexing of 38,7 %. Key Words: bagasse, fiber, rope, spun, tensile test.

Abstract

One way to overcome erosion is using vegetative methods, where its influence can be manifested by the C factor. The best C factors used in determining the amount of erosion is the value of C in the local area. This study was aimed to determine the value of string bean and cucumber crop factors on the Andepts soil during April to August 2013 using the method of small plots and USLE. Parameters used in determining the C factor were the amount of erosion, the allowable erosion rate, and the erosion hazard level. The results showed that the amount of erosion on land without a crop was 0,46 ton (ha.year)-1,on cucumber land was 0,41 ton (ha.year)-1, on string bean land was 0,31 ton (ha.year)-1. The amount of allowable erosion rate was 31 ton (ha.year)-1. While erosion hazard rate on land without a crop was 0,014; on cucumber land was 0,013 and on string bean land was 0,010 which include in low category. The value of string bean crop factor using rainfall research data for 4 months and 10 years data was 0,685 and 0,690 respectively. The value of cucumber crop factor using rainfall research data for 4 months and 10 years data was 0,902 and 0,911 respectively Keywords : Andepts, C factor, Erosion, Kwala Bekala USU.

Abstract

Milling was done to refine food materials to be powder with a certain sieve size in order to be more easily processed into other products. The purpose of coffee beans milling was to refine the beans into coffee powder with a certain sieve size in order to be easily brewed and gives the more optimal sensation of taste and aroma. This research was aimed to design, make, and evaluate the flat burr mill type of bean grinder on robusta cofee bean. The bean quality evaluated was the effective capacity of grinder mill, lost bean persentage, and economical analysis. The results showed the effective capacity of flatt burr type grinder was 5,00 kg/hr and the lost bean persentage was 1,112%. Based on economical analysis, the cost of robusta coffee bean milling was Rp.1.074,25/kg, break even point 2.748,9 kg/year, net present value (NPV) 16% was Rp.6.147,25 ,NPV 20% was Rp.5.397.751,98, and Internal Rate of Return (IRR) was 52.81%.

Abstract

The need of water on the field of durian lingga village was channeled through tertiary canal that made from soil. This can affect the lossing of water. This study was aimed to examine the tertiary irrigation channel in that area. The parameters measured were the physical of soil properties, the discharge channel, the efficiency of the distribution, water loss, flow velocity, slope and size of the channel. The results of the research showed the efficiency of the distribution on line 1 at a distance of 120 m was 63.12% and channel 2 at a distance of 90 m was 66.46%. The efficiency of channeling at a same distance (90 m) with the assumption of losing the water on every meters was the same, was 78.87% on channel 1 and 66.46% on channel 2. The average flow velocity was smaller than the critical speed so that precipitation happened, there for redesign of the channel dimensions was needed. The result of the best design of tertiary channel dimensions for the channel 1 was width of the channel (B) of 0.704 m and depth (D) of 0.352 m with a slope of 0.032%, while for channel 2 the width of the channel (B) was 0.844 m and the depth (D) was 0.422 m with a slope 0.02%. Key Words: tertiary a channel, conveyance efficiency, design of canals.

Abstract

Raja’s banana fibers have the best tensile endurance between the others. The characteristic, could be used making rope that can be used for binding, pulling, trapping, tethering, hanging and others in accordance with the rope usefulness. The research was aimed to know the endurance of Raja’s banana fiber rope with and without NaOH solution on the rope tensile test. Results of the research indicated that the two, three and four twists with and without NaOH 5% during two hour gave the different results of tensile strength, strain, deformation, elasticity and flexing. The highest result of tensile strength was on the three twist condition (with treatment) i.e. 515,92×105 Nm-2. The highest result of strain was on the three twist condition (with treatment) i.e. 1,98. The highest result of deformation was on the three twist condition (with treatment) i.e. 0,099 m. The highest result of elasticity was on the four twist condition (with treatment) i.e. 318,47×105 Nm-2. And the highest result of flexing was on the four twist condition (with treatment) i.e. 64%. Key words: Raja’s banana stems fiber, rope, twisting, NaOH, tensile test.
