Abstract

Stoves are one of the technologies that play an important role in energy utilisation at the household scale. The utilisation of biomass waste as a fuel source is because the waste has a significant energy content. Based on BPS statistics for corn production in 2016, NTB province reached 1,278,271 tonnes and increased in 2017 to reach 2,127,324 tonnes, based on these data it is possible that corn will produce corn cobs that have the potential to be developed into bioethanol and bioenergy. The purpose of this study was to design and build a household scale corn cob waste biomass gasification stove, determine the effect of variations in air flow velocity on room temperature in the combustion process of corn cob waste, determine the comparison of water boiling temperatures at variations in air flow velocity of 5.0 m/s, 10.0 m/s, and 15.0 m/s. The research method used is experimental method by conducting experiments and performance tests in the Agricultural Workshop Laboratory. The research was conducted by varying the speed of air entering the reactor with speed variations of 5.0 m/s, 10.0 m/s and 15.0 m/s. The parameters observed include combustion chamber temperature, water boiling temperature, and initial ignition time. The results showed that the air velocity variation of 15.0 m/s affected the highest combustion temperature with 359.13 with 100 grams of ash, then the highest water boiling temperature was 60℃, and the initial ignition was recorded at 2:20:31 minutes. From the results of this study, it can be said that using the highest speed variation can produce perfect combustion.

Abstract

Ergonomics approach to vehicle design is emphasized on researching the limited capabilities of humans, both physically and mentally psychologically and their interactions in an integral human-machine system. Then systematically the ergonomics approach will then utilize this information for design purposes, so as to create a product system or work environment that is more suitable for humans. Objectives of the Research; Knowing the anthropometry of workers and the furnace knows the process of boiling tofu; determine the suitability of the anthropometry of workers with the tofu boiling process furnace; knowing the level of complaints felt by workers during the tofu boiling process. This study uses quantitative methods, with a descriptive analysis approach to the dimensions of the tofu boiling stove on the anthropometry of the workers' bodies. The instruments used in this research are literature study, observation and interviews. The variable used is the anthropometric data of workers in the manufacture of tofu. The dimensions measured include; hand width, the distance from the fingertips to the left to the right, the height of the hand grip from a vertical hand position up from standing upright, the distance from the hand grip to the back, the length of the hand, and the width of the palm. The body dimensions measured in the study are as follows: body height in standing position, shoulder height, elbow height, shoulder height in sitting position, elbow height in sitting position, shoulder width, hip width, body height in sitting position. The results of this study indicate that the measurement of the dimensions of the body of the community in the city of Mataram obtained varying results. The results of the measurement of body height when standing ranged from 131 to 153 cm and for the average body height of all people measured was 151 cm. Interviews on average workers complained of pain in the left elbow and right elbow and pain in the upper arm. left, right upper arm, right wrist and left wrist. By using the NBM questionnaire which is described in 27 points, the method of collecting data directly to workers by means of direct interviews on the spot is used

Abstract

Groundnut production in West Nusa Tenggara Province has increased every year. Post-harvest handling of peanuts at the farm level is generally still done traditionally, especially when harvesting, threshing pods or stripping the peel, which requires a lot of labour. This study aims to determine the effect of peanut pod diameter on each parameter, tool efficiency, and tool production quality. The method used in this research is the experimental method by conducting experiments directly in the laboratory. The parameters observed in this study are the efficiency of the tool, the need for electrical power, and the quality of peanut seed stripping. The analysis results showed that each treatment with different diameters had no significant effect on each parameter observed. The stripping quality of the three treatments has not met the standard.

Abstract

Simple Drip Irrigation is automatic and cheap plant watering. Simple Drip Irrigation is a plant watering technique that uses a water reservoir or water reservoir can be a used bottle that is given a channel to drip the planting media little by little constantly, so that the planting media remains fulfilled its water needs, without becoming muddy and the water supply remains sufficient. This study aims to determine the water efficiency by using drip irrigation method on the growth of lettuce plants. The method used in this research is an experimental method using a Randomised Group Design (RAK) consisting of 3 treatments, namely 3 replications so as to obtain 12 experimental units, first P1 = 300ml water application, second P2 = 200ml water application, and P3 = 100ml water application and analysed using analysis of variance (Anova) at a real level of 5% and if there is a treatment that has a real effect then a test is carried out using the honest real difference test (BNJ) at a real level of 5%. The results of field research conducted by researchers that the provision of drip irrigation has no significant effect on the parameters of plant height, dry trimmed weight, stem diameter, soil texture but significantly different on wet trimmed weight and for the best treatment obtained in the P2 treatment which produces the highest wet trimmed weight of 93 grams.

Abstract

Infiltration rates across land cover vary depending on the type of land use. Several factors influencing soil physical properties include soil texture, organic matter, bulk density, porosity, aggregate stability, and water content. Low infiltration capacity impacts high runoff rates. Runoff has the potential to carry soil particles dislodged by rainwater to lower areas; this phenomenon is exacerbated if the land lacks shading vegetation. If continued, it will erode the topsoil, thinning the soil solum. The analysis results indicate that land covered by bananas, mixed gardens, heterogeneous forests, and shrubs has a very high infiltration rate. PCA results demonstrate a consistent relationship with basic soil science principles, particularly the relationship between soil structure, organic matter content, and infiltration rate. The positive correlation between porosity and infiltration rate reflects the role of the soil pore system in controlling water movement. The negative relationship between organic carbon and variables on the F1 axis indicates that increasing soil organic matter tends to be associated with changes in soil structure, leading to more stable and aggregative soil structures
