Abstract

The Machining process is manufacturing in the world industry that is widely used. The coolant in the machining process functions to lower the temperature and lubricate and clean the gram in the cutting process. The application of coolant in the cutting process is to maintain the quality of the workpiece during the cutting process and also serves to improve tool life so that the tool does not wear out easily. This study aims to determine the effect of a chemical-based coolant based on dromus oil and vegetable CPO on tool wear in the face milling process and to determine whether or not the liquid is effective in reducing and slowing down tool wear. In this research, the face milling process used a grey cast iron specimen as the workpiece specimen used and also used a carbide insert chisel cutting tool with the TPKN 22 VC2 type. The research was carried out by varying the engine speed and also the coolant variation, the engine speed variations used were 80, 360 and 720 Rpm. In the process of administering coolant using the method, it is sprayed directly onto the workpiece area which is cut continuously, in the milling process with a response variable that can be in the form of data or tool wear values that have been observed and tested using a microscope test tool, using the weight (mass) method to see the wear value. This research aims to see how effective the use of vegetable- based coolant (CPO) during experiments as a coolant in the machining process aims to ensure that the final value of tool insert wear must be smaller with (CPO) compared to chemical coolant (dromus).

Abstract

Monitoring shrimp ponds involves observing and measuring key environmental factors that influence shrimp health and growth. This study was conducted at a shrimp pond on Jalan Paluh Merbau, Tj. Rejo, Kec. Percut Sei Tuan, Deli Serdang Regency, North Sumatra, Indonesia. Traditionally, air humidity and water temperature are monitored manually by taking water samples for laboratory analysis or using litmus paper. These conventional methods are time-consuming and prone to inaccuracies, potentially compromising shrimp health. To address these challenges, this research implemented an Internet of Things (IoT)-based monitoring system to automate the measurement of air humidity and water temperature. The system utilizes DHT11 and DS18b20 sensors, integrated with an ESP32 module, to continuously collect data and automatically transmit it to Google Sheets for real-time monitoring. This IoT approach enables shrimp farmers to easily track water quality parameters, enhancing the accuracy and efficiency of pond management. A two-day testing phase demonstrated stable environmental conditions, with humidity levels recorded at 86.5% to 87.78% and water temperatures ranging from 27.55°C to 28.06°C. These readings were within the ideal thresholds for optimal shrimp growth, showcasing the system's effectiveness in maintaining suitable pond conditions. This research will contribute significantly to more efficient, accurate, and sustainable shrimp farming practices.

Abstract

Currently, in the industrial world, many products or components are required to have strong but light properties. Therefore, aluminum material is increasingly being chosen as the main material in the industrial production process. Aluminum and its alloys are classified as light metals that have high strength, corrosion resistance, fairly good electrical conductivity, and are lighter than iron or steel. However, aluminum has a weakness in its welding ability which is not good when compared to other metals. This problem can be overcome by the Solid-State Welding (SSW) welding method. SSW itself is a welding process carried out when the metal is still solid, meaning that the metal does not melt. One of the SSW methods that is often used is Friction Stir Welding (FSW), which is a solid-state welding technology that is very suitable for joining materials such as aluminum. FSW does not require additional materials, but instead utilizes the heat from friction between the probe and shoulder of the welding tool with the surface of the workpiece. This research on Friction Stir Welding aims to determine the effect of variations in feed rate on the strength of 1100 aluminum joints through tensile tests. The pin tool used is made of carbide, cylindrical in shape with a length of 100 mm and a diameter of 3 mm. The test specimen used was aluminum 1100 with a thickness of 3 mm, a length of 200 mm, and a width of 20 mm, and was made into 9 samples. The FSW welding process and the manufacture of test specimens were carried out according to the ASTM E8 standard. During the welding process, the pin tool rotated at 2200 Rpm, and the feedrates used were 50 mm/min, 100 mm/min, and 150 mm/min. After welding, a tensile test was carried out on the FSW joint results. There were nine tensile tests, with each feedrate parameter tested on three samples. The average tensile strength of the FSW joint on a 2200 Rpm spindle with a feedrate of 50 mm/min was 12.34 MPa, at a feedrate of 100 mm/min was 21.53 MPa, and at a feedrate of 150 mm/min was 29.21 MPa.

Abstract

This study aims to analyze the performance of oil slicing machines on potato chip products that are specifically designed for the needs of small-scale food industries. The machine has a capacity of 10 kg and is operated for 3 minutes per cycle. The test was conducted five times on potato chip samples, with the primary parameters being the weight before and after the slicing process. The average weight of chips before draining is 568 grams, while after draining, it decreases to 529 grams, indicating a 39-gram decrease in mass, which corresponds to a reduction in oil content. The calculation of the thinning efficiency revealed that the engine was capable of reducing the oil content by up to 6.87% of the initial weight. The engine is driven by an electric motor with a rotation of 1380 rpm, transmitted through a pulley system (3 inches: 13 inches), resulting in a tube rotation of 330.5 rpm. These results demonstrate that the slicing machine effectively reduces the oil content of potato chips in a short time, making it suitable for micro and small businesses in the snack sector due to its simplicity, energy efficiency, and cost-effectiveness.

Abstract

Corrosion is one of the most problematic issues in the material industry that may generate tons of drawbacks. In recent years, Kuala Tanjung has experienced an increase related to the development of infrastructure including trestles and docks that are capable to accommodate mother vessels, containers, and stockpile tanks. The growth of industrial estate occurring would lead to a consideration that Kuala Tanjung might be possible to be an International Hub Port. Despite all these development efforts, the detrimental effects could lead to the quality of water, air, and soil caused by industrial waste and consequently the corrosion attack would easily occur. This condition is exacerbated by the lack of atmospheric corrosiveness data in Kuala Tanjung Batu Bara. Then, it is necessary to investigate the corrosion rate using the weight loss method and refer to ASTM G – 1. Specimen dimensions and test racks are designed based on ASTM G – 50 standards. The aim of this study is to investigate the atmospheric corrosion rate of low-carbon steel and map the atmospheric corrosion in Kuala Tanjung, Batu Bara. The research site is divided to six locations, namely points A, B, C, D, E, and F. The Low-carbon steel test specimens conducted use elbow steel profiles, plates, and quadrangles. Testing is carried out for six months with data collected once every two weeks. The results of this study show that the corrosion rate values reach 0.0564 – 0.5230 mpy for elbow profiles, 0.0552 – 0.4984 mpy for plate profiles, and 2.1341 – 5.2022 mpy for quadrilateral profiles. These results indicate that the corrosion rate of low-carbon steel in the Kuala Tanjung is still relatively safe as well as the atmospheric corrosiveness maps can be created at each location.

Abstract

Photodiode sensors are widely used in various applications such as light intensity measurement, optoelectronic devices, and automation. In improving the quality of measurement and automation systems, more sophisticated technology is needed such as photodiode sensor arrays, which allow more accurate data collection from multiple sensors simultaneously. This research aims to design a photodiode sensor array with high sensitivity. The system design consists of six photodiode sensors combined with a summing amplifier circuit and a non-inverting amplifier as a signal conditioner which is then processed by a microcontroller. After that, the linear regression function is determined through the calibration process and experiments carried out. Two linear regression functions are obtained and implemented in two operating modes: normal mode and sensitive mode. Experimental results yield two linear regression functions applied to a photodiode sensor array in normal and sensitive modes. Normal mode shows 82.50% accuracy with a 36.69% coefficient of variation, while sensitive mode boasts 94.05% accuracy and 49.81% coefficient of variation. Both modes cater to different light conditions, with sensitive mode excelling in detecting light intensity. Linear regression implementation proves precise and accurate for light detection.

Abstract

AbstractMesh convergence in finite element analysis is crucial for ensuring simulation accuracy, especially in vehicle coil springs. However, limited studies have evaluated the balance between accuracy and computational efficiency due to mesh size variations. Stress-strain data is obtained from the strain that occurs when driving by installing a strain gauge on the coil spring. This study analyzes the effect of mesh size on stress distribution, deformation, and computation time in the front coil spring of a minibus using FEMAP NX Nastran software. The results show that smaller mesh sizes yield higher stress and deformation values, with a maximum stress of 817 MPa at a 0.1 mesh size and 733 MPa at a 0.6 mesh size. While improving accuracy, finer mesh sizes significantly increase computation time. Therefore, balancing accuracy and computational efficiency is essential for optimizing coil spring design, with further research recommended to determine the optimal mesh size in finite element simulations.Keywords— Mesh Convergence, Finite Element Analysis, Stress Distribution, Computational Efficiency
