Abstract

Indonesia is a country rich in natural resources, particularly coal and coconuts. The purpose of this research is to determine the effect of drying processes and the addition of coconut shell biomass to anthracite briquettes on volatile matter content and ash content. A full factorial method was employed in this study, with three factors: drying temperature, drying time, and water-to-molasses ratio. The results show that the coconut shell biomass added to anthracite briquettes significantly affects the volatile matter content. The lowest volatile matter content, 24.8%, was observed in briquette samples dried at 120? for 90 minutes with a water-to-molasses ratio of 4:3. On the other hand, the highest volatile matter content, 28.1%, was produced by briquette samples dried at 100? for 90 minutes with a water-to-molasses ratio of 4:1. The lowest ash content, 41.1%, was found in briquette samples dried at 120? for 60 minutes with a binder ratio of 4:1, while the highest ash content, 35.8%, was observed in samples dried at 100? for 60 minutes with a binder ratio of 4:3.

Abstract

In order to satisfy the wants and desires of human life, science and technology have advanced quickly. Science and technology are developing in many facets of life. Technological advancements also happen in composite materials, which are still being studied today. Particleboard is a manufactured board created by pressing industrial waste from plantations, forestry, and agriculture together with organic adhesives. Low-quality wood waste products that may contain cellulose and lignin, such as sawdust, twigs, lathing residue, and others, can be used. The PVAc polymer was subjected to temperatures of 90°C, 100°C, and 110°C in this work, which employed a direct experimental method. The parameters used were mesh 10, 20, and 30 with a volume fraction of 60%: 40%, 70%: 30%, and 80%: 20%. In this study, the results of the largest impact strength were found in the volume fraction of 60%:40% on mesh 30 with heating at 90°C for 15 minutes amounting to 16.34 J/m2, and the smallest impact value was found in the volume fraction of 70%:30% on mesh 10 with heating at 100°C amounting to 9.28 J/m2, where these values do not meet the SNI-03-2105-2006 standard for making particle boards.

Abstract

The use of metal materials in the industrial world is increasingly widespread, so that over time metals are becoming increasingly difficult to obtain and people are required to think critically so they can look for alternative materials from the limitations of metals that are easily available and abundant, one of which is composite materials. Composite is a combination of two or more materials with different ingredients. The aim of this research was to determine the effect of thatch stalk length of 50, 60, 70 mm and a volume fraction of 35% with an oven temperature of 90°C for 45 minutes, 40% with an oven temperature of 100°C for 45 minutes, and 45% with an oven temperature of 110°C for 45 minutes when soaking the thatch stalks in 4% NaOH for 2 hours for the bending test. The highest flexural strength value was at a shank length of 50 mm with a volume fraction of 35% with an oven temperature of 90°C of 48.23 MPa. This is because the shorter the thatch stalks, the denser the thatch stalk composite looks and at a volume fraction of 35% the thatch stalks and resin stick well and the oven temperature should not exceed 90°C because if it exceeds the thatch stalks it will shrink and the flexural strength will increase. small.

Abstract

The relatively high number of gasket defects after the finishing process is one of the problems faced by PT. XYZ. The defect is located on the inside of the seal washer, which is not completely cut during the finishing process. The objective of this research is to design and manufacture a flashing trimming blade to reduce the number of defects of seal washer at PT. XYZ. The design stages of the trimmer blade include creating two- and three-dimensional drawings using AutoCAD version 2017, turning iron (blade material) using a CY-1760 lathe, and testing the success and efficiency of finishing seal washer without and with the use of a trimmer blade. The study results show that the trimming blade is capable of finishing the gasket with good performance. By using trimming blade in the finishing stage, the number of defects can be reduced from 359 pieces (20%) to 50 pieces (2.7%), and the finishing time can be reduced by 86% from 70 seconds to 5 seconds per product.

Abstract

The peeling machine for peanut shells, which has limitations and achieves a peeling capacity of only 85%, requires optimization. To this end, the friction, pressure, and gravity involved are analyzed. The design concept of the peeling machine considers the topographic conditions, particularly in the East Nusa Tenggara (NTT) region. The result of this optimization produces the 'Peeling Machine for Peanut Shells.' The resulting peeling machine has the following specifications: height of 700 mm, length of 50 mm, width of 37 mm, operated manually, with a production capacity of approximately 0.86 ounces per second. The performance, in terms of rotation speed and the number of peeled peanuts, shows a significant correlation with increased capacity. Increasing the diameter of the blades also contributes to higher output. At a speed of 60 rpm, a closer blade distance (11 mm) yields the best results, indicating that the optimization of machine design needs to consider the blade distance in relation to the rotation speed to enhance efficiency.

Abstract

This study focuses on the design and performance evaluation of a shallot peeling machine aimed at enhancing processing efficiency for culinary applications. The machine is equipped with a ¼ hp electric motor operating at 1400 rpm, along with a specially designed peeling disc that utilizes rubber friction around the drum to effectively peel the shallots. The machine’s large-capacity container is designed to prevent the test materials from being ejected during operation, ensuring stability throughout the peeling process. Testing was conducted in two stages: the first stage used 1 kg of shallots, and the second stage used 2 kg, both at a motor speed of 1400 rpm. In the first test stage, the machine achieved an average peeling efficiency of 82% after one minute (equivalent to 820 grams of peeled shallots from 1 kg), which increased to 94.2% (942 grams) after two minutes and reached 98.5% (985 grams) after three minutes. In the second test stage with 2 kg of shallots, the machine recorded an average peeling efficiency of 96.4% (1929 grams). The machine demonstrates a production capacity of 30 kg per hour, far exceeding the previous model's capacity of only 14 kg per hour. These findings confirm that the newly designed shallot peeling machine meets performance expectations and offers a substantial improvement in peeling efficiency and productivity.

Abstract

Gas tungsten arc welding (GTAW) is a welding process that is widely used for stainless steel materials, especially material thicknesses below 3 mm. In this study, ASS 316L pipes with a diameter of 89 mm, a thickness of 2.6 mm, and a length of 100 mm using a current of 50A was successful prepared. The type of welding wire used is ER316L with a diameter of 1.6 mm and argon as a shielding gas with using a backing gas. The results of macrograph observations showed that the face tended to be concave and the root experienced over penetration. This was correlated with the results of visual observations, including the face in the weld metal area being lower than the base metal and the root being too deep. The highest average tensile test result is 659 MPa, with a yield strength of 484 MPa, while the elongation is 39.3%, then the fracture form occurs minimal necking or brittle fracture occurs. The highest average hardness test result in the WM area is 188 HV, followed by the HAZ area with an average hardness of 154 HV and in the WM area an average hardness of 148 HV.

Abstract

Traditional air conditioning systems often operate without accounting for the number of people in the room, leading to inefficient energy consumption and reduced comfort. This system uses image processing to detect and count individuals within a space, enabling temperature adjustments between 18°C and 28°C and humidity control around 40%-60%. The process begins with video data captured from cameras, which is analyzed using specific algorithms to identify and track the number of occupants. Based on this data, ITRS adjusts temperature and airflow to maintain optimal comfort while minimizing energy usage. Experimental results show that ITRS can control the AC fan speed setting it to low, medium, or high depending on room occupancy and maintain a target temperature range of 20°C to 25°C. By activating air conditioning only when needed and adjusting output based on occupancy levels, the system offers a sustainable and intelligent alternative to conventional HVAC solutions. This responsive approach enhances energy efficiency while providing a comfortable indoor environment.

Abstract

 Along with the advancement of technology and the increasing busyness of everyday people, the need for tools to help with daily activities is becoming increasingly important, including for pet owners such as cats. This study designs an automatic tool called "Zen-Feeder," which is an automatic pet feeding tool that uses a microcontroller and ultrasonic sensor to detect the presence of cats, provide food on a scheduled basis and according to the dosage so that owners can more freely manage their time and activities outside the home. The ultrasonic sensor detects the presence of cats around the feeding place, according to the characteristics of cats coming to the feeding place when it is time to eat. The tool's servo motor will automatically open the feeding valve when the cat is within a certain distance from the feeding place and release food with a predetermined dosage. Then, the valve will close again. In light of the growing demands of modern life, the development of the "Zen-Feeder" represents a significant advancement in pet care technology, offering convenience and peace of mind for cat owners by ensuring their pets are fed consistently and healthily, even in their absence.
