Abstract

AISI 1020 steel is a low-carbon steel that is currently widely used on the market as a raw material for making industrial and automotive components such as gears. Therefore, it is necessary to increase the hardness of AISI 1020 steel through a heat treatment process, one of which is using the pack carburizing method. This research aims to analyze the microstructure and case of depth of AISI 1020 steel after the pack carburizing process. The pack carburizing method was used in this research because this method can optimally increase the surface hardness of steel. AISI 1020 steel was used as the main material in this research, coconut shell charcoal was added as a carbon source, and Na2CO3 as an energizer. The quenching process uses SAE 20w-40 oil. In this research, the pack carburizing process uses variations in temperature and holding time of 850oC, 875oC, 900oC and 40 minutes, 50 minutes respectively. The results of highest case of depth obtained at a temperature of 900oC with a holding time of 50 minutes of 0.46µm. It can be concluded that the pack carburizing heat treatment process has an influence on the microstructural components of pearlite and ferrite. The case of depth resulting from heat treatment also increases along with increasing temperature and holding time for the pack carburizing process.Baja AISI 1020 merupakan baja karbon rendah yang saat ini banyak digunakan di pasaran sebagai bahan baku dalam pembuatan komponen perindustrian dan otomotif seperti roda gigi.

Abstract

Currently, the energy we use comes from the use of fossil energy. In the future, fossil energy will experience a reduction and will eventually run out because it has limits to its availability. One way to reduce the impact of dependence on the use of fossil energy is to utilize wind energy sources, which are one of the environmentally friendly renewable energies. Currently, the use of wind energy continues to be developed, one of which is a wind energy conversion system which utilizes wind energy sources into electrical energy by converting wind kinetic energy into mechanical energy through wind turbine blades and then converting it into electrical energy through a generator. In this research, we examine how a horizontal shaft wind turbine performs with variations in the number of blades with the aim of obtaining optimal performance coefficient values. The tests carried out in this research were with simulations on Q Balde v 0.96 software with variations in the number of blades from 3 - 5 with a wind speed range ranging from 3 m/s – 12 m/s. The research results show that the best CP value is the 4 blade horizontal axis wind turbine which has a CP value of 6% compared to the 3 blade wind turbine with 4 blades, while the 4 blade horizontal axis wind turbine with 5 blades has a CP comparison value of 4%. Keywords: Fossil energy, renewable energy, performance coefficient, wind turbine, wind energyAbstract Currently, the energy we use comes from the use of fossil energy.

Abstract

Today, environmental problems, especially soil pollution due to inorganic waste or waste that does not decompose, are a major problem and need to be solved, especially in developing countries with high populations such as Indonesia. One of the causes of soil pollution problems is the use of inorganic fibers such as glass fiber and carbon fiber. The use of materials that are not environmentally friendly in the industry will cause environmental problems due to nature's inability to decompose the glass fiber material in nature. The focus of this research is to reduce environmental pollution by using natural fibers such as abaca fiber as an alternative to inorganic fibers. This is due to its properties, namely: low density, good specific strength, low price, and a high biodegradable ability so that it can reduce glass fiber or carbon fiber waste that does not decompose. To support this, abaca fiber needs to be hydrophobic so that it becomes compatible with other materials when combined together with other materials. One of the ways that can be done is by alkaline chemical treatment and acetylation using KOH and CH3COOH. Chemical treatment was carried out by dipping abaca banana fibers into a solution of alkaline compounds and acetylated compounds KOH and CH3COOH with a concentration of 5 M and 10 M for 4 hours. After chemical treatment, the abaca banana fibers were characterized for mechanical properties using ASTM D 3379 standards to determine the tensile strength of the fibers and using an optical microscope to determine the microstructure of the abaca fibers.

Abstract

The increasing consumption of fossil energy causes fossil energy reserves to become depleted and pollutants in the environment increase. One approach to decreasing reliance on fossil fuels is through the use of renewable energy sources. Hydrogen can serve as a substitute fuel option. One of the uses of hydrogen as a renewable fuel is as an addition to gasoline combustion engines. This study includes a review of previous research on the addition of HHO to gasoline engines on the parameters of power, torque, specific fuel consumption, thermal efficiency, and exhaust emissions. The results of a review of previous studies show that the addition of HHO to gasoline engines can increase engine output power, torque, and thermal efficiency and can reduce combustion exhaust emissions and the addition of hydrogen can reduce specific fuel consumption.

Abstract

This research focuses on predicting the performance of photovoltaic (PV) systems using the PVWatts Calculator. The study examines three types of PV modules—Standard, Premium, and Thin Film—under the environmental conditions of Yogyakarta, Indonesia, with simulations set for the year 2024. Input parameters, including geographic coordinates, solar radiation intensity, average air temperature, and module specifications, were collected from reliable sources such as Suncalc. Simulations were conducted to evaluate annual and monthly energy outputs, considering factors such as system capacity, panel orientation, inverter efficiency, and system losses.  The results show that Premium modules achieve the highest energy output, while Standard and Thin Film modules provide nearly comparable performance, making them cost-effective alternatives. Despite differences in efficiency, the performance gap between the module types remains relatively small under similar light intensity conditions. The findings highlight the importance of selecting PV modules based on specific needs, budget constraints, and environmental factors to optimize solar energy system performance. This study provides a comprehensive framework for PV performance calculations using PVWatts and offers valuable insights to support renewable energy development in the Yogyakarta region.

Abstract

Solid carburization can increase the hardness and wear resistance of steel compared to other methods. In this study, carburizing was carried out using temperatures of 700⁰, 800⁰, 850⁰, 900⁰. With this number of variations, the researcher will analyze the physical properties and mechanical properties of ST60 steel after undergoing carbon pack carburizing. In the Rockwell hardness test, the ASTM E 140-02 standard is used. In the Rockwell hardness test results, the hardness value of the raw material before pack carburizing increased after the material was carburized. Thus, the temperature in the carburizing process affects the hardness of the material. Then in the results of the raw material microstructure test, there are more ferrite crystals than pearlite. While the microstructure in pack carburizing has more pearlite crystals than ferrite. This shows that the steel workpiece has increased hardness after undergoing the carburizing process.

Abstract

Ducted propeller is an engineered propeller drive which aimed to enhance thrust force. Many ways can be done in purpose to enhance thrust force, such as geometry variation in term of Ld/D ratio. Ld/D ratio is a ratio between duct length and duct diameter. In this research, an analysis was conducted using numerical simulation. This research used two Ld/D ratio (0.4 and 0.5) and three propeller angular velocities as the variables (1000, 3000, and 5000 rpm). The result of this research showed that higher Ld/D ratio produced higher thrust force. At 5000 rpm the thrust fore increased 26.3% on duct with Ld/D ratio of 0.5. Moreover, higher propeller angular velocity produce higher fluid velocity at the ducted propeller outlet. The highest fluid velocity reached at 5000 rpm propeler angular velocity with the value of 9.8 and 10.8 m/s.Keywords: ducted propeller; Ld/D ratio; numerical simulation; thrust force

Abstract

The PLC System in Vertical Plastic Injection Molding Machine is an automated electrical system designed with sensor inputs controlled by a PLC Mitsubishi FX0s-20MR. It is supplemented with additional devices such as Proximity switches and Thermocouple PID-CX100. The research aims to analyze the heater temperature to control the movement of the injection piston for controlled movement, enhancing the efficiency of the molding injection process, and preventing operational errors that could affect the machine's condition, performance, and the molding results. From the experiments conducted, it was found that the settings producing specimens with near-perfect or perfect results were in experiments number 5 and 6. The injection time in these experiments was successfully adjusted using a timer setting in the PLC program, with an automatic injection time of 15 seconds. Based on these results, it can be concluded that the optimal settings for the molding process using PP material in this equipment are a temperature of 200-210°C, pressure of 4-5 bars, and injection time of 15 seconds.
