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

This research aims to design and develop coil heater technology as an alternative heat source to replace wood in the brick-firing process. The research methodology involves the design of an efficient and environmentally friendly coil heater and its implementation in the brick production process. In this study, the performance of the coil heater is analyzed to ensure that the generated heat is sufficient for the brick-firing requirements. The research findings indicate that coil heater technology is capable of providing the necessary heat to achieve optimal temperatures in the brick-firing process. Furthermore, the use of this coil heater technology successfully reduces dependence on wood as the primary fuel source. The implementation of coil heater technology in the brick-making industry is expected to make a positive contribution to the environment and the sustainability of natural resources. This research stimulates innovation in the development of alternative technologies that can reduce carbon footprints and improve the overall efficiency and sustainability of brick production processes.

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.

This research focuses on analyzing power losses due to load imbalance in the medium-voltage distribution network in Pasar Aceh. The aim is to determine the magnitude of power losses that occur at the distribution substation in Pasar Aceh. The research method involves analysis, calculations, and simulations using the ETAP 12.6 software. The results of the analysis indicate that load imbalance in the Pasar Aceh substation leads to power losses. The Trafo Samping Pasar Aceh experiences power losses of 0.77% with a load imbalance of 16.33%. The second transformer in the BNI 46 area incurs power losses of 0.98% with a load imbalance of 30.33%, and the transformer in the BLKG KOTTY area has power losses of 1.17% with a load imbalance of 50.33%. These findings affirm that the greater the load imbalance, the higher the resulting power losses in the electrical distribution network.

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.

Abstract

Early childhood education (PAUD) is very important to prepare an educated generation for the nation and state, and the role of early childhood educators (PAUD) is very important in the development of students. Educators need to go beyond traditional learning by providing learning innovations that utilize information technology, including the ability to master the latest information technology. The focus of the Community Service Program (PKM) is to improve   the quality of human resources (HR) of PAUD organizers in Syiah Kuala District, Banda Aceh Province in the field of information technology, so that they are able to support the management of learning and educational activities. In improving the quality of kindergarten teaching staff in the field of information technology is related to supervision management and making daily learning implementation plans (RPPH). With a system that allows teachers to quickly resolve administrative problems, it is hoped that they can use their time to further develop their knowledge and skills regarding PAUD administrative problems.

Abstract

Building a safety culture in the home or family environment will tend to be more difficult than building a safety culture in the workplace. This community service program aims to provide health and safety education to housewives in Naga Umbang Village, Lhoknga District, Aceh. Through various outreach activities, such as seminars, workshops and practical demonstrations, it is hoped that housewives can increase understanding and awareness of the importance of good health practices and safety measures in everyday life. It is hoped that the results of this program evaluation can provide constructive input for continuous improvement and increasing the welfare of local communities.
