Abstract

The increasing demand for coconut productin in Sungai Kupah Village, Kuburaya Regency has resulted in workers needing a tool that can complete work more quickly and effiently. The tools used today stil use wedges where their use takes a long tie because the process in the process relies on human power. In additin, with non-ergonomic work positins, workers can also experience several work-related diseases such as back pain and back pain. The objecties of this research are (1) Designing an ergonomic coconut peeler according to consumer needs (2) Testig the performance of the tool (3) Testig worker fatiue before and aftr using the tool (4) Testig the level of consumer satifactin. The solutin used in this study is the VDI 2221, CVL method approach, measuring tool performance and analyzing the level of satifactin. The results obtained in this study are (1) produce a tool design according to consumer needs and have paid attntin to ergonomic aspects (2) The design of this tool produces a fairly fast stripping tie of 143 peeling fruit/hour when compared to tools using a wedge, namely 92 peeling fruit/hour (3) Worker fatiue test aftr using this tool showed 14.42 % of coconut owners, 11.20 % of worker 1 and 10.48 % of worker 2. This test resulted in CVL below 30% where workers did not experience fatiue. (4) Respondents feel comfortable with the designed tool as evidenced by the results of the 4.8 Linkert scale. Meanwhile, for ease of operatin, the result is 4.3, which means that respondents fid it easy to operate the designed tool. The conclusion in this study is that the currently designed tools are quite effctie, ergonomic and able to reduce the level of worker fatiue.

Abstract

Solar energy is the energy that is most easily obtained in the conditions of our country which is in an area that is crossed by the equator. Energy that can be in the form of sunlight and heat from the sun can certainly be used as alternative energy to produce electrical energy. One technology that is able to utilize solar thermal energy is a solar parabolic trough system as a solar thermal collector. From the heat source produced, it is expected to be able to produce electrical energy generated by thermoelectric, where the thermoelectric heat side is obtained from the heat source in the solar parabolic trough. By conducting experiments to manufacture a power plant that utilizes a solar parabolic trough which is integrated with a thermoelectric type TEG-SP1848-27145SA as many as seven pieces, then the experimental data is taken from the device capable of producing electrical energy output. The output of electrical energy in the form of electrical voltage produced is strongly influenced by the difference in temperature on the hot and cold side of the thermoelectric, the greater the temperature difference, the greater the energy output that can be generated. From the experimental results, the highest temperature difference produced is 20.7oC with a current value of 85.93 mA and a voltage of 2.51 volts in the direction facing north, and the highest temperature difference produced is 11.5oC with a current value of 77.63 mA and a voltage of 2.15 volts in the direction facing east to west. The highest thermoelectric efficiency is 14.996% with the direction of the solar parabolic trough facing east to west.

Abstract

Fused Deposition Method (FDM) is one of the additive manufacturing methods or methods used by 3D printers. This FDM technology can produce models with a fairly good level of accuracy and strength. However, until now information about the magnitude of the value of accuracy, and the value of strength is very minimal. Because of this, it is necessary to do a test to determine the strength value of the specimens produced using 3D technology printing. The tests carried out aim to obtain settings optimal parameters on a 3D printer using PLA material which is measured by the magnitude of the tensile strength value of the resulting product. The test is carried out by measuring the amount of stress that occurs when the tensile test is carried out. The test was carried out using 81 samples that were printed using the parameters of infill print speed, fill density, extruder temperature, and layer height. Based on the test results, the highest stress value is 1.092 N/m2 with a combination of parameters infill print speed 60 mm/s, fill density 40%, extruder temperature 200oC, and layer height 0.1 mm. The results of the analysis show that the parameter extruder temperature has the greatest influence on the magnitude of the tensile test value, while the layer height parameter has the smallest effect on the value of the test specimen.

Abstract

In the metal heating process, a tool is needed that can help the heat treatment process, namely a furnace where there is a space inside to warm up the workpiece to a certain temperature and hold it for a certain time interval. In this study, the furnace design was carried out using Autodesk Fusion 360 software, while the manufacture of the furnace uses several components such as A1 kanthal wire as a heating element, SK34 refractory brick, and Castabel C16 cement which is used as a heat retaining material. Performance analysis is carried out by calculating the speed of reaching the maximum temperature that can be achieved, the time required to reach the maximum temperature, and energy consumption. Based on the results of design and calculation, a furnace with external dimensions of 40x30x40 cm and heating chamber dimensions of 18x18x18 cm was produced. Furnace trials were carried out by melting aluminium material where the melting point of the material in its pure state is 660oC. Further tests carried out show that the maximum temperature that can be reached is 700oC, while the time required to reach that temperature is 50 minutes with an energy consumption of 2,404.6 Watts.

Abstract

There are many types of reinforcement that can be used in the making of composites, and one of the more recent and popular ones is fiber-reinforced polymer. There are many types of fibers that can be used for the composite; this experiment will focus on natural fibers, specifically palm branch fiber and Areca catechu trunk fiber (Known locally in Indonesia as Pinang) with epoxy as its matrix. The composite will be constructed with different parameters, such as different NaOH treatment time (1,2, and 3 hours), pinang: palm fiber composition (50:50, 30:70, and 70:30) and fiber orientation (Horizontal, Vertical, and Random). Through the tensile strength, it's been found that the average strength is 3.07 MPa, where the highest value is 4.04 MPa with the NaOH treatment time of 1 hour, pinang: palm fiber composition of 30:70, and fiber oriented vertically.
