<![CDATA[The need for electricity is good for the industry, offices, and public and individuals are greatly increased. However, the increase in demand for electricity is not accompanied by the additional power supply. Based on these problems, chosen solar energy as an alternative energy to generate electric power. A tool that is used here is the solar cell because it can directly convert solar radiation into electrical energy (photovoltaic process). So that solar energy can be used at night, then during the day, the electrical energy generated is stored before a battery which is controlled by the regulator. Regulator output is directly connected to the inverter from the DC to AC. The test results of solar modules (photovoltaic) indicated that the results of the average power output reached 38.24 Watt, and the currents were 2.49 A. This is because the photovoltaic follows the direction of movement of the sun and always located at the photovoltaic to remain facing the sun. Therefore, it will still be able to capture the radiant sun to the fullest.]]>

<![CDATA[The use of plastic and goods made of plastic have been rising in day to day. Increasing use of plastics is a consequence of the development of technology, industry and population. On one hand, the invention of plastic has a remarkable positive impact, because it has many advantages compared to other materials. But on the other hand, the plastic waste has negative impact that too worried, so its solutions need to be looked for. One of the alternative handling of plastic waste that currently extensively researched and developed is converting plastic waste into fuel. Converting plastic waste into fuel oil can be done with cracking process. There are three kinds of process that is hydro cracking, thermal cracking and catalytic cracking. Fuel oil produced from the cracking of plastic waste depending on the plastic type, cracking process used, catalyst type, pyrolisis temperature and condenser temperature.]]>

<![CDATA[For the sake of the smooth process of cement production, it is necessary to maintain each component of the production. One of the tools that play an important role in the maintenance and production of cement is the Overhead Traveling Crane, which is a combination of a separate lifting mechanism with a frame to lift and move loads that can be hung freely or attached to the crane itself. The problems that arise in the Overhead Traveling Crane include the reverse direction of the motor rotation due to an error in the motor connection, the motor cannot start due to a disconnected power supply, the occurrence of bending (curving) on the girder due to lifting operations that exceed the maximum capacity which can also accelerate service life. of the girder, wear on the wheel due to high workload during operation. Due to the need for very long use, periodic maintenance is needed so that it can be in normal condition for a long time. The main parts that support the overall weight of the crane are rails and wheels. This journal discusses the analysis of failures that occur due to contact between rails and wheels that occur in a cement factory. Failure analysis is done by testing the hardness of both the wheel and the rely which is considered to have failed or is no longer suitable for use. Then review the results of direct field observations with data from hardness tests and literature studies related to wheels and rails. after that it was concluded that the company considered for the procurement of rails and wheels. The conclusion obtained is that the hardness value on the rail is lower than on the wheel. Resulting in failure of the rail so that the rail must be replaced.]]>

<![CDATA[One of the tests used to determine the mechanical properties of metals is the tensile test. The results obtained from the tensile test are crucial for engineering and product design as they provide data on the strength of materials. AISI 1045 carbon steel is an alloy steel composed of iron (Fe) and carbon (C), where iron is the base element and carbon is the main alloying element. Carbon steel is also used in the manufacturing of helical/coil springs (Mobil Alvanza 2020). Coil springs are widely used in the front suspension of modern light vehicles. A new approach to fatigue prediction based on a combination of FE simulation using ABAQUS is opposed in this study. In this research, the tensile test was performed using experimental and ABAQUS simulation methods. The experimental results showed a yield strength of 350.25 MPa and an ultimate tensile strength of 560.4 MPa, while the ABAQUS simulation results showed a yield strength of 356.05 MPa and an ultimate tensile strength of 560.39 MPa]]>

<![CDATA[The Nagan Raya coal-fired power plant in Aceh, Indonesia, serves as a major supplier of electricity to the region's power grid. However, the power generation unit of the plant, which supplies reactive power to the subsystem, often experiences disturbances that cause voltage values in the Banda Aceh substation system to decrease. This decrease in voltage can be detrimental to the quality of power supplied to the consumers. To address this issue, a capacitor bank with a capacity of 25 Mvar was installed at the end of 2016. The capacitor bank was successful in increasing the voltage value at the substation and proved to be an effective solution. However, with the anticipated growth in load in the coming years and the possibility of future disturbances in the power generation unit, it has been proposed that an additional capacitor bank unit with the same capacity be installed to further enhance the voltage quality at the Banda Aceh substation. To assess the feasibility of this proposal, simulations were carried out using ETAP 12.6.0 software. The simulation results show that the addition of a 25 Mvar capacitor bank unit would lead to an increase in the substation voltage value of around 5-6 KV. This increase in voltage would help to maintain the quality of power supplied to the consumers and ensure that the power grid remains stable even in the event of disturbances in the power generation unit. Overall, the proposed installation of an additional capacitor bank unit would be a cost-effective solution to enhance the voltage quality at the Banda Aceh substation and ensure the stability of the power grid. This solution could be adopted by other power plants facing similar issues in maintaining voltage quality in their power grid systems.]]>

<![CDATA[Maintaining the temperature and pH of water in fish farming is important to maintain the survival of the commodities being cultivated. Snakehead fish as one of the freshwater fish cultivation commodities, live in a temperature range of 25° to 32°C, and a pH of 4,5 to 6. Changes in temperature and pH due to differences in day and night and weather conditions can be mortal for the fish. To help the fish farmers maintain water quality, in this research a prototype of IoT based temperature and pH monitor and control was built using Arduino microcontroller, that can be accessed through a mobile application on Android smartphone. The test results show that the prototype has successfully control the temperature by turning the heater on when it dropped below 25°C, turned the acid solution pump on when the pH felt below 4.5, and alkaline solution pump when pH was above 6. Continuous sensor readings are able to maintain the stability of water quality.]]>

<![CDATA[This study aims to determine the value of the sound absorption coefficient of cat tail fiber (Typha latifolia) with the effect of weight and pore size resistance of the test sample plate. In this case the researchers made 6 test samples where each sample consisted of cat tail fibers weighing 50 grams and 75 grams with a diameter of 110 mm and a thickness of 20 mm, the test samples were arranged in layers with aluminimum plate resistance which had a pore size of 1 mm, 1.5mm, and 2.5 mm. Tests were conducted using the impedance tube transfer function method (ISO 10534-2:1998) at frequencies of 1/1 octave (125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz and 8000 Hz). The test results show that the sound absorption value at each frequency of each sample is relatively different. At a frequency of 125 Hz - 250 Hz the best sound absorption was obtained in the test sample with a pore size of 1 mm 75 g, at a frequency of 500 Hz the best sound absorption was obtained in the test sample with a pore size of 1.5 mm 75 g, at a frequency of 1000 Hz - 8000 Hz the best sound absorbing coefficient value occurred in the test sample with a pore size of 1 mm 75 g. From the graph it can be concluded that the pore size of the aluminum plate and density in each test sample can affect the sound absorption value.]]>
