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 Hybrid natural-natural fibre reinforced polymer composites become attractive alternative to seek the friendly-environmentally materials. Study on the durability level of the hybrid composites have the importance reason due to the role in application as structural function. This study focuses on examining the fatigue strength of polypropylene polymer composites reinforced with hybrid sugar palm-kenaf fibres. The hybrid composite materials were prepared by mixing the fibres and matrix with several compositions. There are five composition types of specimens that evaluated, such as 70:10:10, 70:15:15, 70:20:10, 80:10:10 and 90:5:5. The hybrid composites were composed by PP, sugar palm fibre and kenaf fibre. Furtheremore the tensile test were conducted to find the value of ultimate tensile strength for every specimens of hybrid composites. The fatigue test also were conducted with four level of stress i.e. 80%, 70%, 60% and 50%. The results show that in the lower level of stress, the hybrid composites with higher content of sugar palm fibre posses the better performance of fatigue life compare to the others

The rehabilitation of irrigation pumps plays a crucial role in ensuring sufficient water availability for rice fields in Gampong Limpong, Darussalam District. A significant challenge faced by farmers in this region is the malfunctioning of irrigation pumps, which leads to suboptimal water distribution. This issue directly affects agricultural productivity and the welfare of farmers. Through rehabilitation efforts, damaged pumps are either repaired or replaced with more efficient units. The rehabilitation process involves the identification of damages, repair of key components, and operational trials to verify optimal pump performance. Results from this initiative indicate a more stable availability of irrigation water, thereby enhancing crop yields for farmers. This rehabilitation not only offers technical solutions but also fosters active community involvement in maintaining the sustainability of the irrigation system. Consequently, this program contributes positively to the development of the agricultural sector in Gampong Limpok.

This community service program aims to increase the production capacity of the creative rencong souvenir industry through mentoring in mastering mass printing technology. The rencong, as a traditional Acehnese weapon, has been transformed into a souvenir product with significant economic potential, yet it remains constrained by the limitations of conventional production techniques. Through this program, craftsmen and small and medium enterprises (SMEs) in the rencong souvenir sector receive intensive training and mentoring on efficient and high-quality mass printing techniques. The methods employed include technology transfer, hands-on training, and continuous monitoring to ensure program sustainability. The expected outcomes are improved productivity, production efficiency, and product quality standardization, ultimately enhancing the competitiveness of the creative rencong souvenir industry in both local and national markets. This program is also designed to positively impact local economic empowerment while preserving Aceh's cultural heritage through innovative creative industry products.

Pyrolysis is a thermo-chemical which decomposition of organic material through heating process with absent or little oxygen (anaerobic). The purposes of study are design pyrolyzer of coconut shell being to alternative fuels, knowing much of oil from pyrolysis process with method of counter flow and parallel flow, and knowing heat energy or caloric energy which was produced from pyrolysis process with method of counter flow and parallel flow in condenser. The research with through experiments the pyrolyzer which includes reactor, distribution pipe, and condenser.

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.
