Abstract

Pembuatan kapal adalah proses manufaktur multi-tahap dengan berbagai sumber yang khas dengan fungsi kompleks dan membutuhkan kualitas konstruksi yang tinggi. Beberapa hal penting dalam pengendalian kualitas pembuatan kapal seperti perencanaan pada desain kapal, material yang digunakan, dan metode pengendalian kualitas. Era globalisasi menuntut industri galangan kapal terus meningkatkan efektivitas dan efisiensi pada proses produksinya, sehingga mampu bersaing dari segi quality, cost dan on time delivery (QCD). Tujuan dari penelitian ini yaitu untuk mengetahui berbagai metode pengendalian kualitas pada proses manufaktur kapal diberbagai negara di dunia. Penelitian ini menggunakan metode sistematik kajian literatur dari berbagai artikel yang telah terbit yang kemudian diidentifikasi dan di analisis yang berfokus pada berbagai metode pengendalian kualitas pada proses manufaktur kapal. Beberapa metode diperoleh berdasarkan hasil pencarian, diantaranya adalah function-oriented quality control (FOQC), quantitative evaluation method, artificial intelligence, toyota production system (TPS), tacheometer sensors, design point generation method, dimensional & accuracy control automation, a differentiation-based approach, computer-based applications, statistical process control (SPC), inspection test plan (ITP), multi-layer quality function deployment (QFD). Industri perkapalan akan terus menghadapi berbagai tantangan di masa depan, termasuk persaingan global yang semakin ketat, tuntutan untuk meningkatkan efisiensi dan produktivitas, serta perubahan teknologi.

Abstract

This report describes efforts to implement renewable energy technologies as a solution to meet the energy needs of the fishing community in Lam Awe, Aceh Besar. A community engagement approach was used to integrate renewable energy technologies into the daily lives of the fishing community. The study includes the process of identifying community needs, selecting appropriate technologies, and implementing renewable energy solutions. Research methods included participatory surveys, training sessions, and mentoring to ensure active participation and deep understanding from the local community. The results indicate that the implementation of renewable energy can enhance energy access, reduce operational costs, and support environmental sustainability in coastal areas. This report contributes to the context of sustainable technology application for fishing communities, highlighting the importance of collaboration between academics, practitioners, and communities in developing sustainable energy solutions.

Abstract

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. Research methods are the experiment of pyrolysis process at temperature 35oC during 60 minutes with condensation method, counter flow and parallel flow. Results of experiments are data of gas fuels mass obtained 42 grams which used pyrolysis process of coconut shell in the amount of 1000 gr, until produces pyrolysis oil as 198 grams (counter flow) and 196 grams (parallel flow). Counter flow method can absorb a heat as 1304,762 kJ and heat loss through gasses as 462,842 kJ, even though parallel flow no more than absorb as 1200,83 kJ and heat loss through gasses as 545,271 kJ.

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

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

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
