Abstract

This study was conducted using the Computational Fluid Dynamics (CFD) method using the Reynolds Averaged Navier Stokes (RANS) approach. The type of airfoil used in this study is the asymmetry NACA 4415 airfoil type. In this paper, computational tests were carried out on the airfoil with the addition of bionic flaps on its trailing edge. This study's update tests three variations of the Reynolds number: Re = 106, Re = 5 × 105, and Re = 3 × 105. The airfoil test was carried out at AoA 0°–25°. The addition of bionic flaps causes a decrease in lift performance at low AoA, but at high AoA, it can increase lift performance on airfoils. In addition, adding a bionic flap on the airfoil can delay the occurrence of a stall. At AoA 10°–13°, the Cd of the three variations of the Reynolds number experiences an increase in performance. Then, from this computational test, the resulting Coefficient moment (Cm) is a pitch down because the torque is below zero.

Abstract

The rapid development of the industrial world has made it a necessity for companies to compete with their competitors. Therefore, companies must control the quality of their products well, one of which is by analyzing defective products. The purpose of this research is to analyze the level of defects in Toolbox products produced by PT KSKB and provide improvement suggestions to reduce the level of defects in PT KSKB Toolbox products. This research uses data on the number of productions and the number of defective products obtained through field observations and interview processes. The method used in this research is the Seven Tools and Kaizen Five-M Checklist method of improvement analysis. Based on the data processing results, there are three types of defects in Toolbox products: burrs, materials with holes, and cutting with no precision. The most frequent type of defect is burrs (an uneven surface of the object due to the working process), with a value of 52.12%. Meanwhile, from the analysis of the Kaizen Five-M Checklist, periodic training (training and OJT) needs to be conducted for employees, routine machine maintenance needs to be carried out, standard operating procedures need to be evaluated, and work areas need to be evaluated to create a safe and comfortable working environment so that the level of product defects can be reduced.

Abstract

Papua province has nine small islands that are inhabited, but there is no access to electricity on these islands. The solution is the use of sea wind as a source of energy for a small power plant. This study aims to determine the potential of sea wind as an alternative source of electrical energy on the north coast of Papua Province. Data Measurement is carried out using an HP-866B anomometer on a hill near the coast to maximize the sea wind. There are two methods used in this research: the minimum-maximum value to determine the wind speed range and linear regression to determine the distribution pattern of the wind. The range of the sea wind is 0.2–6.18 m/s. If the minimum speed is limited to 1.6 m/s, then the range of kinetic energy is 5.59–322.22 Joules/s, mechanical power is 5.59–322.22 Watts, and actual power is 0.57–33.13 Watts. Meanwhile, the pattern shows that the sea wind from the north coast of Papua Province blows with two trends: constant and increasing, specifically in the afternoon and evening. Based on that, the development of a wind power plant on the north coast of Papua Province can be carried out using a multi-turbine system to increase the actual power that can be obtained.

Abstract

This study investigates the effect of the increased welding layers welded by the SMAW process on distorsion, thickness, microstructure, hardness, and corrosion. The method used in this research is experimental. Low-carbon steel with a size of 150x10x10 mm was welded by the SMAW technique using an HV 450 electrode. Variations in the welding layers are single, double, and triple. The three variations of the samples were observed with a digital camera and an optical microscope. Moreover, samples were tested with a hardness tester. Corrosion testing was also carried out to determine the corrosion rate of the layers formed. The results showed that the number of SMAW welding layers affected the thickness, phase, hardness, and corrosion rate. The hardness of one layer is less than that of thicker specimens, while the corrosion rate of three layers is lower than that of less-thick samples.

Abstract

A tensile testing machine with a lower load capacity is needed to identify the mechanical properties of composite materials. Tensile testing machines for composite materials are available in the market but at high prices. Previously, using a pneumatic system, a tensile testing machine for composite materials with a maximum load of 2000N was developed. However, this tensile test machine still needs improvement because the display of eventuating forces is only in numbers, not yet including a test graph. Therefore, this study developed a prototype data acquisition system for a tensile test machine to record the test results in more detail, both numbers and graphs. This data acquisition system uses the Arduino Uno Microcontroller, which processes data from the load cell through the HX711 module intermediary. A tensile test was carried out using a bamboo fiber composite material to validate the results of testing the prototype of this data acquisition system. Furthermore, the test results data are compared with the results on the indicators of the existing tensile test machine. The test was carried out nine times with an average tensile force of 1.66 N/mm2, while the average tensile force on the tool indicator was 2.02 N/mm2. There is a difference in the average test results equal to 12%. This difference is a systematic error because nine experiments have shown the same trend, with standard error and standard deviation of 0.3368 and 0.1123, respectively. The systematic error is compensated through calibration between the load cell of the tensile test machine and a series of data acquisition systems based on Arduino Uno.

Abstract

The brake pads made from asbestos are environmentally hazardous due to the friction and abrasion occurring during braking, resulting in the release of airborne asbestos fibers. These fibers pose various health risks to humans and contribute to environmental pollution. This study aims to analyze the influence of adding clamshell waste material on the mechanical properties of motorcycle disc brake pads. The research utilized an experimental approach, conducting tensile and friction tests on six samples with different compositions: 100% brake pads, 40% brake pads, 60% simping clamshell, 60% brake pads, 40% simping clamshell, 20% brake pads, 80% simping clamshell, 50% brake pads, 50% simping clamshell, and 100% brake pads. The results indicate that the sample comprising 50% used brake pads and 50% simping clamshell exhibited the smallest difference in thickness, measuring 0.05 mm or 0.59%, indicating the strongest adhesive strength and wear resistance compared to other variations. Thus, a higher simping clamshell composition sacrifices some tensile strength but offers improved elasticity, benefiting specific braking conditions.

Abstract

Commercial water flow meter costs increase when utilized in low-cost installations like pico-hydro, small-scale process industries, irrigation, and other rural or non-commercial technology applications that require measurements of water discharge. Utilizing a low-budget flow meter equipped with a freely available microcontroller is the answer to this issue. In contrast to commercial measuring devices, this low-budget measuring instrument needs to be examined and verified ahead of time using other commercial measuring devices to establish the measurement's uncertainty value and make it feasible to use. By using the Arduino Uno microcontroller and the YF-DN40 turbine sensor, this low-budget flow meter is capable of producing <5% difference in discharge readings and <1% measurement uncertainty.

Abstract

The need for electrical energy in Nehibe village is currently increasing along with the increase in population and new households. The demand for electricity in this village reaches 18 kW, with an average power per household of 450 VA. The problem is that Hachakwa Nehibe Micro Hydro Power Plant (PLTMH), which is very close to the village, has a capacity of only 10 kW. Based on that problem, this study aims to design a peltor turbine with two nozzles for the new 26 kW PLTMH. This power plant uses the water from the Tena Mroway and Yora Mroway rivers, which are located 2 km from the end of the village, as a new source of energy. This design of the turbine is based on the mathematical equations, measurement data of the head, and the flow of the rivers. This research shows that the Pelton turbine with two nozzles (nj), 0.032 meters of jet diameter (Dj), 0.330 meters of runner diameter (Dr), 0.096 meters of bucket diameter, and 21 buckets can produce 26 kW of power with 60 ltr/sec of river flow and 77 meters of head height. This specialization can be used to develop the new PLTMH in Nahibe Village.
