Abstract

A clinker cooler is a very important piece of equipment in the cement industry because it functions to cool the slag or clinker that comes out of the kiln. In the cement industry, the processed clinker is first heated in a rotary kiln at °C and then lowered to temperature again. Next, the crossbar hammer crusher driven by the drive plate crushes the clinker. Clinker is transferred from the cooler inlet to the cooler outlet by this device. The performance of the main clinker cooler due to small errors can cause the kiln to stop working or disrupt other operations, such as in the mile finish area. In certain cases, cement production was disrupted due to a break in the crossbar component in the clinker cooler using the tested software Ansys Workbench 2020. It is hoped that the data from this simulation can be used as a benchmark between the results of the simulation, it can be used as a benchmark between the results of the best modified design for increasing crossbar durability through statistical loading tests with the FEA method.

Abstract

Areca nut husk fibers have the potential to be used as reinforcement in polymer composites as a substitute for synthetic fibres. In the manufacture of fibre composites, one of the important factors in determining the strength is the matrix to fibre ratio. This study aims to determine the effective ratio or fraction between areca nut husk fibre and orthophthalic polyester resin. Before using areca nut husk fibre, it was chemically treated so that only cellulose remained in the fibre. The areca nut husk fibre was processed into sheets. The composite was manufactured using the hand lay-up technique. Tensile and flexural tests were carried out to determine the mechanical properties. Based on the results of the tests conducted, there are differences in the mechanical properties of the composites. The tensile test results show that the 40% fibre fraction has the highest tensile strength and modulus values. On the other hand, in the flexure tests, the highest tensile strength and modulus values are found in the 30% fibre fraction.

Abstract

This qualitative study focuses on occupational safety and health in vocational school machining workshops to identify significant risks related to training practices. Workplace accidents are considered a serious threat to workers and equipment, potentially affecting productivity and environmental safety. Observations at several vocational schools, especially at SMK Negeri 1 Batipuh, showed low student awareness and compliance with OHS regulations, increasing the risk of risky behaviour and accidents. To address this, the research used the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method, which systematically identifies hazards, evaluates risks based on severity and likelihood, and proposes control measures. The research at SMK Negeri 1 Batipuh involved direct observation, interviews, and analysis of SOPs in the workshop, finding significant risk variations in workshop conditions, lathe operations, welding, material handling, hand tool use, and machine protection. The results highlighted the predominance of intermediate risks in all-hazards analyzed, emphasizing the importance of developing more effective risk management strategies. This research aims to reduce accidents and improve student safety during training by addressing existing OHS implementation gaps and implementing appropriate risk controls. In addition to filling a gap in the literature, this study provides practical insights for improving OHS practices in vocational schools.

Abstract

Energy consumption of a building is one of the biggest sources of energy use today. Green Building Comitte Indonesia (GBCI) has launched a concept of energy consumption saving in a nationally standard building. Audit Building energy audit is the way to know how actual building energy consumption is and find alternative solution to decrease energy consumption in order to fulfill the energy saving building criteria. Two types of HVAC systems will be run in the EnergyPlus simulation, split AC and central AC. The previous research proved that central AC is better than split AC system for energy saving in the building with 20 floors. The simulation results show that by using a certain energy system, a more efficient energy system will be achieved and can still maintain the comfort of the room at a temperature of 24 °C and relative humidity according to the Green Building Indonesia standard reference.

Abstract

The island country is a characteristic of Indonesia, and is located right on the equator stretching from the island of Sumatra to the island of West Papua. The need for electrical energy is increasing, but the energy generally used to produce electrical energy is fossil energy, and the problem faced by most countries, including Indonesia, is the problem of energy reduction. According to the International Energy Agency (IEA), the electricity needed is 14 terawatts per day, arguably the equivalent of 210 million barrels of oil. The objectives of this research are (1) to design a wind turbine using fiberglass as the basic material, (2) to make a turbine that can utilize wind energy for electricity generation purposes, and (3) to determine the performance of a modified 4-blade vertical wind turbine on the power it produces. can be generated. The type of research carried out uses experimental methods. The test results show that wind turbines made from fiberglass are able to achieve wind turbine efficiency of 50.7%. The conclusion drawn is that the researchers succeeded in designing a wind turbine from fiberglass as the basic material, the wind turbine can rotate properly and can produce electricity. The generator power produced increases as the wind speed increases. A wind turbine using 4 blades at a wind speed of 21.6 m/s, produces a rotation per minute of 250.6 rpm, produces 108.20 watts and a torque of 107.14 Nm.

Abstract

Solar panels are renewable energy which is very useful for agricultural needs to meet electricity needs, one of which is its application in agriculture, namely as a pump driver for hydroponic plants. Hydroponics is farming with an emphasis on meeting the nutritional needs of plants using water as a medium with a nutrient solution as fertilizer. In the hydroponic system the pump must be on continuously, for this reason the Automatic Transfer Switch (ATS) tool is used to substitute the electrical energy of the State Electricity Company (PLN) with the electrical energy of solar panels in the event of a power outage from the State Electricity Company (PLN) which aims to drain nutrient water. This research aims to apply solar panels to a hydroponic plant system and apply the Automatic Transfer Switch (ATS) tool as a substitute for the State Electric Company's (PLN) electrical energy and solar panels. This research was carried out on Jalan Polonia no.11 fresh water east, North Padang District, Padang City, West Sumatra in January – March 2024, with the initial stages (1) preparation, (2) solar panel assembly, (3) analysis of test results , (4) preparation of reports. The results of this research can determine the power output required by solar panels as a renewable energy source as well as the application of the Automatic Transfer Switch (ATS) in hydroponic plant cultivation.

Abstract

Recycling is the process of converting used materials into new materials with the aim of preventing waste that can actually be useful, reducing the use of new raw materials, reducing energy use, reducing pollution, land damage. The purpose of this study was to determine the most optimal pouring temperature to produce the best casting of the physical and mechanical properties of recycled aluminum material added with degasser powder. The urgency of this study is as a research material in the field of materials. This research method is to make 3 variations of melting temperature before pouring into the mold, the temperature variations used are 6750-7000C, 7000-7250C and 7250-7500C. At any temperature variation before pouring into the mold, degasser powder is also added to help clean the molten metal from the gases trapped in the molten metal. After the sample is molded, the results are visually observed, then a specimen is made to test the mechanical properties of the used aluminum casting. The data from the test results show that there is a fairly large porosity value in each variation. The hardness value of the test results shows that it is directly proportional to the temperature variation. At a temperature of 7250-7500C the average hardness value is 98.5 HVN. While the tensile strength at a temperature of 7250-7500C value is 83.58 Mpa, at a temperature of 7000-7250C = 74.39 Mpa and at a temperature of 6750-7000C = 71.5 Mpa. Thus the most optimal temperature in this used aluminum casting is 7250-7500C.
