Abstract

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.

Abstract

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.

Abstract

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.

Abstract

The distribution system of electrical power begins from generation and is transmitted to the load, namely consumers. In this distribution, it must be effective, efficient, and reliable. The amount of electrical power reaching the load is not the same as the amount of power generated due to voltage drop or power losses. This research aims to determine the magnitude of power losses in the medium-voltage distribution network located in Pasar Aceh. The research method employed is the analysis and simulation calculation method using ETAP 12.6 software. The study analyzes power losses due to load imbalance in the JTR distribution substation of Pasar Aceh. Based on the analysis results, the load imbalance in the Pasar Aceh substation has led to power losses. The power losses in the Pasar Aceh substation, specifically at the Side Transformer of Pasar Aceh, are 0.77% with a load imbalance of 16.33%. For the second transformer in the BNI 46 area, the power losses are 0.98% with a load imbalance of 30.33%, and for the transformer in the BLKG KOTTY area, the power losses are 1.17% with a load imbalance of 50.33%. Therefore, the larger the percentage of load imbalance in an electrical distribution network, the greater the resulting power losses.

Abstract

This experimental study examines the impact of speed variations on the 2.5 mm nozzle diameter in low-carbon steel laser cutting. The primary objective is to optimize the roundness of the cut by considering cutting speed factors. Through a series of experiments conducted on low-carbon steel plates measuring 200 mm x 200 mm, utilizing a 2.5 mm nozzle diameter with speed variations of 2, 3, and 4 m/minute, the research measures roundness quality using a digital caliper. Results indicate that cutting speed influences roundness quality, with the lowest deviation observed at a speed of 2 m/minute and the highest at 3 m/minute. The study also highlights that increased cutting speed and the use of a larger nozzle require higher gas pressure.

Abstract

This study was focused on the characterize the hibridisation of kenaf and sugar palm fibre in reinforcing the polypropylene matrix. Addition of MAPP (Maleic Anhydride Polypropylene) was used as compatibilizing agent with variation of 2%, 3% and 5%. The specimen materials were prepared with 30% amounts of fibres while the ratios between kenaf and sugar palm fibre are 10:20, 15:15 and 20:10. The composites were fabricated using melt mixer technique and followed by compression molding process. The specimens were cut according ASTM Standard D790 for conducting the flexural testing. After testing done, the results shown that flexural strength of composites tend to decreased when the content of MAPP increased. The ultimate flexural strength was attained at 2% MAPP addition of the hybrid composites with 20% kenaf fibres. Among the composites with different ratios, the hybrid composites that contain more kenaf fibres exhibit the higher value in flexural strength than the composites that contain more sugar palm fibres.
