Abstract

The mangosteen fruit (Garcinia mangostana L.) or nicknamed the queen of fruit is one of Indonesia's leading fruits. The mangosteen fruit consists of components in the form of seeds, fruit, pulp (pulp), and fruit skin. This mangosteen rind flouring device is a tool to assist in the flouring process in large quantities using an electric motor as a driving force. The method used in this research is an experimental method by conducting experiments directly in the field and in the laboratory. The design used was a completely randomized design (CRD) which consisted of 3 treatments using variations in the stages of material entry (load), namely: P1 = Load 100 g with a rotation of 1430 rpm, P2 = Load 200 g (100 g + 100 g) with a rotation 1430 rpm, P3 = Load 300 g (150 g +150 g ) with a rotation of 1430 rpm. The data analysis used in this research is a mathematical approach using Microsoft Excel and a statistical approach using ANOVA diversity analysis and a 5% BNJ follow-up test. This study uses 3 parameters, namely, capacity (kg/hour), power requirements (watts), and engine efficiency (%) with results that have no significant effect. The results of the design of the mangosteen rind flouring device of vertical type with dimensions of 58 cm long, 43 cm wide and 63 cm high. The effective working capacity of this mangosteen rind powder is found at P3 of 342.92 g/second with an output rotation of 1430 r pm which is used in testing the tool. The effective electric motor power is at P1 the average motor power usage is 7.08 watts. The percentage of engine efficiency in this study is found in P1 of 63.83%.

Abstract

The main source of energy for humans is natural resources derived from fossils. Scarcity and rising oil prices will continue to occur due to its non-renewable nature. This must be immediately balanced with the provision of alternative energy sources that are renewable, abundant and cheap so that they are affordable by the wider community. The use of briquettes is based on the increasing price of petroleum in the global market. Charcoal briquettes are charcoal that is further processed into briquettes (special and more attractive appearance) that can be used for daily purposes. This study aims to determine the best raw materials in making quality briquettes. The method used in this research is an experimental method with experiments in the laboratory. The design used is a completely randomised design (CRD) consisting of 5 treatments as follows, P1: 100% corn cob, P2: 75% corn cob + 25% rice husk, P3: 50% corn cob + 50% rice husk, P4: 25% corn cob +75% rice husk and P5: 100% rice husk. Observation data were analysed using Anova (analysis of variance) at the 5% level. If there is a significant difference, then it is continued with the honest real difference test (BNJ) at the real level of 5%.  The lowest value of water content was P5 which was 47.44%, in the stability of the smallest shape change was P1 4.0%, the least particle loss was P1 0.35% and the longest burning time was P3 at 113 minutes. Based on the research results, the best treatment is P3 where the moisture content value is 47.64%, with particle loss of 0.77%, and the longest burning time is 113 minutes.

Abstract

In order to meet the water needs of tomato plants and ensure that they grow well, an adequate irrigation water supply systems that are ideal for tomato plans. This analysis aims to 1] determine the effectiveness of drip irrigation techniques on tomato plant growth on dry land, and 2] assess the impact of drip irrigation techniques on plots given silver and straw plastic mulch, as well as properties without both. This research used an experimental apporoach that included both field and laboratory experiments. A one-factor randomized blog design (RBD) was used in this analysis, with three treatments: P1 = no mulch and straw, P2 = silver color plastic mulch, and P3= straw. The least significant difference method (LSD) was evaluated at the 5% actual level using SPSS analysis. Observation data were analyzed using two apporoaches: a mathematical apporoach using Microsoft excel and statical analysis using ANOVA analysis. The serults showed that the parameters of plant height, stem diameter, and the number of leaves of tomato plants had a significant impact on P1 ( no mulch and straw), P2 ( Silver Color Plastic Mulch), and P3 (Silverr Color Plastic mulch) (straw). It applied drip irrigation techniques to the growth of tomato plants in dryland. Although tomato plant wet weight and tomato plant dry weight parameters had a significant impact on tomato  plant growth and dry weight than P1 and P3. It results in an average wet weight of 162.678 grams, P1 24.05 grams, P3 81.10 grams, and an average dry weight of 31.62 grams, P1 5.84 grams P3 18.74 gram, respectively.

Abstract

This study aims to determine the working mechanism of the vertical type mangosteen peel penepung machine, to determine the production capacity of the results of the performance analysis of the vertical type mangosteen peel penepung machine, to determine the electrical power requirements and to determine the efficiency of the machine the results of the performance analysis of the vertical type mangosteen peel penepung machine. The method used in this research is the Experimental method by conducting experiments in the Agricultural Workshop Lab. The design used is a Completely Randomised Design consisting of 3 treatments using a vertical type mangosteen peel penepung machine with load variations, namely, P1 = 50 grams, P2 = 100 grams, P3 = 150 grams using a 1400 rpm rotation. Each treatment was repeated 3 times so as to get 9 experimental units. The research data were analysed using load variations (Anova table) at the 5% level and if there was a treatment that had a significant effect, further tests were carried out using the Real Differential Test (BNJ) at the 5% real level. The results of the analysis and research show that the working mechanism of the machine uses an electric motor as a driving force, the highest mangosteen skin pressing capacity in P3 is 177.80 grams / second and the lowest in P1 80.82 grams / second, the use of the highest electrical power requirements in P3 0.17 watts and the lowest electrical power usage P1 is 0.09 watts and the efficiency of the machine in P1, P2 and P3 is the same at 53.33%.

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
