Abstract

Air pollution is increasing due to emissions from fossil fuel motor vehicles so that electric vehicles are one of the solutions to reduce pollution produced from vehicles. The increase in electric vehicles makes the need for sources of electrical energy increase. Solar panels are an alternative source of renewable electrical energy. Utilization of solar energy requires a battery that functions as energy storage. This research was tested at a distance of 100 meters at a stable speed of 19.78km/h. The results of the test will be read with a data logger system consisting of a voltage sensor, current sensor, speed sensor with Arduino UNO as a microcontroller and Micro SD as a storage medium and an LCD display to display data as a reference during testing in real time. The results of this study are, with the same distance and speed, the total power consumption of LiFePo4 batteries is on average 305.13W greater than Li-Ion. With an average power consumption of 86.17W for LiFePo4 and 69.22 W for Li Ion. Li Ion batteries have the advantage of longer battery life due to less power consumption. Meanwhile, LiFePo4 batteries have the advantage of producing higher power so that vehicle performance is also more optimal, as well as better current and voltage stability which results in more stable power consumption. Keywords: Lithium Ion battery, LiFePO4 battery, transport e-scooter

Abstract

Community Service (PPM) is held in Sumberejo Village, Sanankulon District, Blitar Regency. Chicken farmers face several challenges related to heating their chicken coops, including restrictions on using subsidized fuel or LPG, which force them to seek other heating alternatives. Leaks in heating systems that use LPG, which pose a fire hazard. Poor air quality and low oxygen levels in coops that use conventional heating methods (firewood and LPG). These challenges can contribute to the decline in the quality of Day-Old Chicks (DOC). This activity aims to install an electric warmer system that produces a safe and comfortable temperature for Day-Old Chicks (DOC) and is easy to use for breeders. In addition, build an independent energy source to run the heat treatment system equipment in the DOC-Brooding area with a solar panel installation. The installed 600 Wp PLTS system consists of 4 solar panels with a capacity of 150 Wp each, an 850 VA hybrid inverter and 100 Ah VRLA battery. Electrical energy from PLTS can power a 200 W electric warmer. The solar panel installations can produce an average of 3.6 kWh of electrical energy/day. So that the electricity savings from PLN can reach IDR. 162000 per month.

Abstract

Working in the mining sector has a fairly high occupational risk, especially for mechanics in carrying out heavy equipment maintenance. One of the maintenance carried out is the replacement of the excavator bucket. The excavator bucket is mounted on the end arm of the excavator which is connected using a locking pin. The pin installation process is carried out by hitting with a hammer, where this process has a number of occupational risks such as being hit, exposed to material, and fatigue which can result in work accidents. This study aims to minimize the occurrence of occupational risks by finding out the relationship between the use of special tools on safety and job duration for the locking pin installation process. The method used is experimental quantitative method and using fishbone diagram. By using a special tool, the installation of locking pins becomes safer because the factors that cause accidents when using palju can be eliminated and the manpower required becomes more efficient, but in terms of time it requires a longer duration due to the limitations of the tool that requires adjustment several times when used.

Abstract

Solar energy as renewable energy has great potential to supply the world's energy needs. Solar thermal energy can be used for domestic energy purposes (cooking and water heating). The purpose of this research is to develop, design and analyze the performance of a solar cooker from the concentration of direct normal irradiance (DNI) by the Fresnel lens on the receiver/absorber as a cooking vessel. One form of improving the performance of the Fresnel solar concentrator (FSC) is the addition of an automatic solar tracker installation using hydraulic actuators. The solar tracker is varied, every 5 and 10 minutes, respectively. The solar cooker performance test was conducted outdoors at the Mechanical Engineering Department of State Polytechnic of Malang (7.9553 oS and 112.6125 oE) in April 2021. The method used actual experimental research. The measurement of solar radiation uses a solar power meter SPM-1116SD and the tracker's movement. At the same time, the temperature parameters (water temperature, receiver wall temperature, focal point temperature, ambient temperature) are measured by the temperature data logger. The concentrated solar cooker type design uses a fresnel lens with a capture area of 0.785 m2 and a focal ratio of 0.88. The main components of this solar cooker design consist of: a large fresnel lens that functions as a concentrator of sunrays, a cone-shaped cooking stove as a solar collector (receiver), and a hydraulic actuator-type solar tracker unit. Initial tests showed that the solar radiation, In = 789.00 W/m2, obtained the focal point temperature at the receiver, Tf = 930.10°C. Meanwhile, the thermal efficiency (Th) of a solar cooker with a solar tracker that moves every 10 minutes and 5 minutes is 12.7% and 33.66%, respectively. The increase in the thermal efficiency of the solar cooker is very significant, which is 2.65 times. This shows that the more accurate and continuous movement of the tracker will increase the thermal efficiency of the designed Fresnel solar cooker.

Abstract

The Aims of this study are to determine  the effect of embossing roll roughness and forming temperature on the damage of menthol-coated aluminum foil on the packaging, and to determine the best temperature and embossing roll roughness on the quality of the menthol coating on the packaging. In this study, the independent variables were embossed roll wave (roughness level 1000,500.0 µm) and menthol foil temperature (22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46 °C) to be manipulated, observed, and measured to know the effect with the dependent variable. And because the established variable is the quantity of broken menthol foil packaging that is measured via way of means of calculating the share of period of menthol foil packaging this is torn as compared to the whole period of the foil. Based on the effects of the discussion, it can be concluded that the forming temperature and the embossing roll roughness affect the damage to the menthol packaging layer. In the ANOVA follow-up test, the lowest and best mean value for the forming temperature is at T12 or 44°C, not at T13 or 46°C because at these temperatures the menthol layer on the package is too hot and starts to damage the coating and the lowest and best average for the roughness level of embossed rolls is at E3 with a roughness value of 0 µm (fine).
