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.

Abstract

Bio-composite roof tiles use polypropylene matrix material and rice straw fiber as reinforcement processed by compression molding to create innovative and sustainable building products. This research aims to analyze heat distribution from the cartridge heater in the mold core during the compression molding process for fabricating bio-composite roof tiles. The research employs Finite Element Analysis (FEA), and laboratory experiments to measure temperature distribution and heating efficiency. The results showed that even heat distribution on the mold core is crucial to ensure optimal final product quality. Manual calculation estimated a heating time of 170.78 seconds to reach the desired temperature. Simulations conducted using Ansys R19.2 software shows that the temperature variation on the surface of the mold core can be minimized with the optimal placement of the heater cartridge. The simulation results obtained a time of 10 seconds to reach a temperature of 200℃ gradually. Laboratory experiments support the simulation results by showing that good heat distribution improves bio-composite tile materials' mechanical strength and homogeneity. This research significantly contributes to the design and optimization of mold cores for bio-composite applications. It offers practical guidance to the industry in improving the efficiency of the production process.

Abstract

This study examines the design and safety analysis of an automatic liquid filling machine for bottles with two modes: 250 ml and 500 ml. The problem addressed is the time-consuming and inconsistent manual bottle filling process in UMKM. The machine is designed to improve efficiency and consistency in filling liquids for UMKM. Made from PLA filament using 3D printing, the machine has dimensions of 400 mm x 350 mm x 350 mm and was analyzed using Finite Element Analysis (FEA). The load on the machine is 2.4516625 N for 250 ml and 4.903325 N for 500 ml. Simulation results show a maximum stress of 0.114 N/mm² for 250 ml and 0.118 N/mm² for 500 ml, both below the PLA material's yield strength of 26,082 N/mm². The maximum displacement is 0.002 mm for 250 ml and 0.00894819 mm for 500 ml. The minimum safety factor is 4,044e+02 for 250 ml and 1,156e+02 for 500 ml. These results confirm that the machine design is safe and reliable for automatic liquid filling in both modes.

Abstract

Cooling systems play a crucial role in maintaining the operating temperature of machines, with coolant as a key element to absorb, transfer, and release heat. This study aims to analyze the effect of coolant-water mixture concentration on its dynamic viscosity. Experiments were conducted using three different water concentrations (90%, 80%, and 60%) at a total volume of 250 mL. Data were obtained from flow time measurements through a tube of specific length and diameter, and dynamic viscosity was calculated using Poiseuille's Equation. The results indicate that higher water concentrations reduce dynamic viscosity, making the fluid flow more easily. These findings provide valuable insights for developing more efficient coolant formulations, enhancing the performance of cooling systems in various mechanical applications.
