Abstract

This study investigates the development and implementation of a dual-axis solar tracking system for off-grid 100Wp photovoltaic (PV) systems to enhance energy harvesting efficiency and ensure sustainable power generation. The research addresses the limitations of fixed-tilt PV systems, which often underperform due to suboptimal solar alignment, especially in regions with dynamic weather conditions. The results demonstrated a significant increase in energy output, achieving up to 13,75% higher efficiency compared to static systems under similar operational conditions. This improvement is attributed to the system's ability to maintain optimal solar panel orientation throughout the day, facilitated by an advanced tracking algorithm and real-time sensor integration. The distinctive features of the developed system include its cost-effective design, adaptability to various geographical locations, and robust performance under fluctuating environmental conditions. The findings suggest that the dual-axis tracking system is wellsuited for deployment in remote or off-grid areas where reliable and efficient power generation is critical. Practical applications of this system are particularly relevant for rural electrification, agricultural irrigation systems, and other decentralized energy solutions in regions with abundant solar resources.

Abstract

Hot-Gas Welding is a welding process that is widely used in plastic materials. In previous studies, there was a phenomenon that occurred, namely the early connection of the parent material before the welding process which affected the tensile strength of HDPE sheets. The purpose of this study was to determine the effect of variations in root face height and width of the anvil heating plate on tensile strength, and also to determine the interaction of the two variables. The welding process of Hot-Gas Welding, by varying two independent variables namely root face height 0 mm, 0.8 mm, 1.6 mm, 2.4 mm and the width of the anvil heating plate 10 mm, 15 mm, and 20 mm. The controlled variables include HDPE material 5 mm thick, HDPE filler 4 mm thick, hot gas temperature 250 ℃, single v bevel shape, anvil plate temperature 150 ℃ and v grove angle 60º. The results of this study indicate that the root face height and anvil plate width affect the tensile strength of hot-gas welding HDPE sheets. The maximum value of tensile strength is 27.09 Mpa or 85.32% of the tensile strength of the parent material. The maximum tensile strength value is obtained from the interaction of the root face height of 2.4 mm and the width of the heating plate of 15 mm. Distortion and linear misalignment weld defects at the highest tensile strength results were identified the least.

Abstract

This study aims to analyze and simulate the aerodynamic performance of the design of a training weapon grenade using the Computational Fluid Dynamics (CFD) method. CFD simulation allows the analysis of airflow around the grenade to identify the distribution of pressure, drag, and aerodynamic coefficients that play an important role in the efficiency of the grenade flight. The grenade design was tested under various conditions of speed and fin angle to understand their effects on stability and flight efficiency. The results of the simulation show that the variation of the mortar grenade with the fin position parallel to the launch angle has a fluid flow velocity of 84.1 m / s, the mortar grenade with the fin position tilted 2.5 has a fluid flow velocity of 82.7 m / s, and the mortar grenade with the fin position tilted 5 has a fluid flow velocity of 85.8 m / s from the data obtained, the inclination of the fin angle significantly affects the aerodynamic performance of the mortar grenade. This study provides insight that shifting the fin angle on the grenade can increase stability and minimize air resistance during flight.

Abstract

This study aims to analyze the effect of various operational factors on the weight of dust collected by a dust collector machine. Using a multilevel factorial design, this study evaluates the interaction between frequency (Hz), hose length (m), and tube height (m). Analysis of variance shows that all three factors have a significant effect on the dust weight response (P-Value <0.05). The regression model with an R² of 99.15% shows a very high prediction accuracy. Parameter optimization was carried out to maximize the weight of dust collected, resulting in optimal conditions at a frequency of 50 Hz, a hose length of 2 m, and a tube height of 0.3 m with a dust weight of 72.75 g.

Abstract

This research is to direct the mixture of air and fuel exactly to the top of the midpoint of the dome in the cylinder head. In addition, Squish Head also determines the character of the motorcycle. Moreover, what is very prominent in the initial pull is that if the compression ratio is denser, the pull is lighter.This study aims to determine the effect of changes in the slope angle of the squish head of 15, 17 and 19 degrees on compression and torque. In this study, experimental research is used with a quantitative method, where information that can be calculated and measured is factual because it is in the form of numbers. Researchers to get the data will conduct tests using the dynotest tool.Changes in slope of the squish head have an effect on the torque. At an angle of 15 degrees, torque is produced at 9.91 N.m at 6000 RPM engine rotation. At an angle slope of 17 degrees, the torque increases by 0.14 N.m to 10.05 N.m at 6000 RPM engine rotation. At an angle of 19 degrees, the torque increases by 0.17 N.m to 10.22 N.m at 6000 rpm.

Abstract

This study aims to analyze the effect of the number of poles on the output power of the Permanent Power Generator (PPG). PPG is an innovative renewable energy system that utilizes permanent magnets to generate continuous electrical power without relying on external fuel sources. This study uses an experimental approach using 1 mm diameter wire and three pole configurations (3, 6, and 9 poles) to determine the optimal configuration to maximize power output. Voltage and current measurements were taken using a digital multimeter, and the power output was calculated using the formula P=V×I. The results showed that an increase in the number of poles significantly increased the generator's power output. The highest performance was achieved with a 9-pole configuration and a 1 mm wire diameter. These findings support the basic principles of electromagnetism, where a decrease in coil resistance and an increase in magnetic field frequency contribute to higher energy conversion efficiency. This study is expected to contribute to the development of environmentally friendly power generation systems and serve as a valuable reference in the design of high-power, high-efficiency generators for future renewable energy technologies.

Abstract

In this modern era, technological developments are growing so fast, from information technology, communication technology, transportation, medical to industrial technology. One of the advances in the rapidly developing industrial world is the technique of coating metal or material surfaces. There are many methods of material surface coating techniques such as Physical Vapor Deposition (PVD), implantation, radio frequency (RF) sputtering, chemical vapor deposition, polymer supported electrodes (PSE), and electrochemical deposition. The Electrochemical Deposition method is a simple method with cost advantages, but this method requires processing of liquid waste which has recently become a public concern regarding environmental pollution. The APD (Arc Plasma Deposition) method has a higher level of satisfaction in fulfilling the requirements for deposition of a material, namely it is easy to control the size of the particles to be deposited and is faster in the deposition process and also has a very small impact on environmental pollution. This method requires quite large assets for its application so not many people know the stages of layer deposition. Therefore, the preparation of a prototype of a laboratory scale thin film growth machine was carried out and can carry out the deposition of a material onto a material. To optimize the layer growth results, adjustments are required in the machine parameter settings and the pure gas rate used

Abstract

Lubricating oil was type of fluid needed by a machine to work. Significant changes in the temperature of the lubricating oil viscosity up to low level made the engine components less lubricated. It caused the engine components to heat up quickly due to the friction between the metals that became greater. Poor quality lubricant could cause deposits to appear in the engine room which resulted in the engine working harder. The purpose of this study was to investigate the effect of the use of cooking oil added with surfactants of estolides and diglycerides with percentages (2.5%, 5%, and 7.5%) as engine lubricants on engine temperature and power produced by motor vehicles. The research method used was an experiment on a 125cc gasoline motorcycle lubricant with standard conditions. The data taken in this study included engine temperature and power. The results showed that with cooking oil mixed with 7.5% estolides surfactants after heating produced power with an average value of 6.52 HP and a mixture of 5% diglyceride surfactant producing an average value of 5.87 HP, which had a higher average value compared to oil rated at 5.37 HP. When using 2.5% estolides, the lowest value was 83.67°C and using a diglyceride percentage of 7.5% produced the highest value, namely 107.03°C. The use of cooking oil had an influence on engine temperature and power. The average power value of 5.71 HP was higher than oil with a value of 5.37 HP. The engine temperature value using cooking oil was 92.7°C lower than oil with a value of 96.63°C

Abstract

In the automotive world, power reduction in long-used motorcycles is a common issue that can affect vehicle performance. Over time, engine components experience wear and decreased efficiency, leading to reduced power output. One solution to address this problem is optimizing ignition settings by upgrading the CDI (Capacitor Discharge Ignition) and replacing the standard coil with an aftermarket coil. Upgrading the CDI and replacing the standard coil with an aftermarket one aim to improve engine power, as the standard CDI has a relatively low output and the standard coil has a limited output capacity. Therefore, the coil must match the output capacity of the upgraded CDI. This study aims to enhance the performance of a 110cc four-stroke engine. The study method used is a quantitative experimental approach, and data processing is carried out using two-way ANOVA analysis of the test results, processed in Microsoft Excel, with the average results taken from three trials per variation. The independent variables in this study are the racing coil with a voltage greater than the standard (up to 90 kV) and ignition timing mapping with a programmable CDI, while the dependent variable is power. The results of the study show that the ignition timing set at 13 degrees and the use of the BRT coil provided the highest power output, reaching 8.33 horsepower at 8000 rpm. This outcome is due to the critical role of ignition timing in controlling fuel combustion in the combustion chamber, where an earlier explosion with a larger spark results in higher power output
