Abstract

ABSTRACTSoil tillage aims to create physical soil condition suitable for plant growth. It does that by improving soil water and air association as well as water movement in soil. Mechanical soil tillage requires lots of energy; therefore, good tillage practice needs to carefully consider a proper soil condition in order to get the required result. A technical test to Kubota tractor type M9540 with 95 horsepower was done in this research, as it has never been done before in specific soil condition, topography, and climate of the North Sulawesi. The objectives of this research were to measure aspects of effective field capacity and field efficiency, fuel consumption, to calculate tillage cost and tractor Break Even Point. Soil tillage results were also evaluated by measuring soil bulk density, water infiltration and moisture content before and after tillage. The test was done by cultivating the dry land through performing primary and secondary tillage, each was carried out in three replications. The results show that average effective field capacity for first primary tillage was 1.55 m2/second (0.56 ha/hour), second primary tillage was 1.75 m2/second (0.63 ha/hour), and the secondary tillage was 2.72 m2/second (0.98 ha/hour) with average field efficiency was 77.40%, 80.72%, and 56.17% respectively.Total time to complete the first and second primary tillage was 0.11 hour and 0.10 hour, with diesel fuel consumption of 64.17 liters/ha, and 55.44 liters/ha. The secondary tillage required 0.06 hour and fuel consumption of 28.72 liters/ha.The primary and secondary tillage were found to influence the soil moisture content, bulk density, and rate of water infiltration. Tillage basic cost is calculated as Rp.1.765.683 /ha to result a hire charge of Rp. 1.942.251 /ha, and the tractor break-even point was found to be 552 ha/year.Keywords: Tractor, tillage

Abstract

ABSTRACTThis study aimed to calaulete the field efficiency of direct seed planting equipment (Tabela) using a hand tractor as a pulling tool. The field evaluation was conducted on an area of 120 m2 that was divided into 3 plots. In this study the distance between planting rows was 20 cm, the legowo rows distance was 40 cm the average of planting depth was 1,4 cm, the the seed number each hole was 3-7 seeds and the average was 4 seeds. The results showed that the field efficiency was 53,53 %. This direct seed planting equipment reduced the number of labors and working time.  Keywords : Tabela tool, Hand Tractor, Legowo

Abstract

ABSTRACTThis study aims to compare the quality of liquid smoke products using three raw materials,namely shell, coconut fiber and corn cobs. This research is expected to provide informationabout the manufacture of liquid smoke that is more efficient, so that it becomes the basis for thedevelopment of a more efficient liquid smoke maker in the future. Liquid smoke is a liquidsmoke vapor condensate resulting from the pyrolysis of wood. Phenolic compounds, carbonyland organic acids contained in liquid smoke play an important role as odor removers andrepellents. Thus it can be seen that the method of fumigation with liquid smoke can be easierand cheaper in plant care.This study used an experimental method and analyzed descriptively. The materials used in theprocess of making this liquid smoke were 90 kg shell, 90 kg coconut coir and 90 kg corn cob.Each treatment in the combustion process of making liquid smoke as much as 30 kg.Observations in this study were carried out from the comparison of raw materials to achieve thedesired liquid smoke results.From the results of the research, the yield of liquid smoke from the shell was 6.027 % 2. withthe performance of the tool 66.96%. The yield of corn cobs was 3,458% with the performanceof the tool 49.4 and the yield of the coconut coir was 2.964% with the performance of the tool49.4%. 3. With 30 kg of raw material for each shell, coconut coir and corn cobs require differentproduction times. The shell takes 9 hours, coconut coir 6 hours and corn cobs 7 hours.

Abstract

ABSTRACTThe Cultivator Motoyama MTE 70NL is an agricultural tool and machine provided by theGovernment of South Minahasa Regency for farmer groups in Modoinding District, for thedevelopment of upland projects. This cultivator is used for secondary tillage. Meanwhile, it isnecessary to know the performance of the tools distributed to farmers, so a study is needed tounderstand how the performance of the Motoyama MTE 70NL cultivator is like for tillage bothin conditions without rain and in rainy conditions. Rain conditions are used as a parameter tocompare cultivator performance with conditions without rain. In the treatment of soil conditionsafter rain, the calculation of rainfall is not carried out, even so after the rain is adjusted to the soilconditions, if the soil is too wet, it will be waited until the soil conditions can be processed. Thepurpose of this study was to analyze the performance of the Motoyama MTE 70NL typecultivator for tillage in 2 treatments, namely treatment 1 on soil conditions without rain andtreatment 2 on soil conditions after rain. The area of research land used is 5m x 30m on a flatexpanse. The variables observed in this study include: depth of tillage layer, speed, workingwidth of the tool, travel time, head land, fuel oil, and tool rpm. The results of this study indicatethat tillage using the Motoyama MTE 70NL cultivator in the first treatment resulted in a traveltime of 12.49 minutes, a head land of 49 seconds, fuel oil 213.14 ml, a depth of tillage layer of30 cm. In the two treatments, the travel time was 13.13 minutes, the head land was 50 seconds,the fuel oil was 219 ml, and the depth of the tillage layer was 30 cm. The engine RPM is 2,416.2r/min and the slow rotary gear rpm is 74.4 r/min. In treatment 1 KLT 0.074 ha/hour, KLE 0.071ha/hour, EL 95.94%. In treatment 2 KLT 0.074 ha/hour, KLE 0.069 ha/hour, EL 93.24%.Keywords: Cultivator, Soil Processing
