Abstract

The use of large amounts of fossil fuels can pollute the air with significant amounts of carbon monoxide. Proton Exchange Membrane Fuel Cell (PEMFC) is an attractive alternative because it is able to generate high current with low working temperature, fast start-up time, no pollution, and good durability. In PEMFC systems, bipolar plates are one of the main and important components. This component facilitates the reactants to flow through the designed channel. This study aims to modify the parallel-type flow field design on the bipolar plate using CFD simulation in ANSYS, in order to improve the performance of PEMFC. While flowing through the bipolar plate, the reactants diffuse through the gas diffusion layer, thus connecting with the catalyst layer to generate protons and electrons in the anode and water and heat in the cathode through chemical reactions. The results of the study show that the variation of rib width and channel depth has a significant effect on the pressure distribution and hydrogen flow distribution.These findings can contribute to the improvement of flow distribution efficiency and pressure reduction

Abstract

The lack of soap production capacity, which currently only reaches 5-10 liters of soap per production, has prompted a team of lecturers at the Manufacturing Engineering Applied Masters Study Program (MTRTM)-PNJ to take the initiative to organize and donate a soap mixing machine. The purpose of this implementation is to increase the amount of community soap production, as well as increase community knowledge and skills regarding soapmaking processes and tools. The training was carried out by delivering material on how to use and tricks for making soap with a mixer machine, which was then continued by making soap by PKK women and ending with a survey of the training implementation. From the results of the training, it was found that soap production increased to 20 liters in one production run, as well as an increase in community knowledge and skills in the process of making soap with a mixer machine. Kurangnya kapasitas produksi sabun yang saat ini hanya mencapai 5-10 liter sabun satu kali produksi, membuat tim dosen di Program Studi Magister Terapan Rekayasa Manufaktur (MTRTM)-PNJ berinisiatif mengadakan dan menghibahkan mesin pengaduk sabun. Tujuan dari pelaksanaan ini adalah untuk meningkatkan jumlah produksi sabun masyarakat, serta meningkatkan pengetahuan dan keterampilan masyarakat terhadap proses dan alat pembuat sabun. Pelatihan dilakukan dengan penyampaian materi cara penggunaan dan trik pembuatan sabun dengan mesin pengaduk yang kemudian dilanjutkan dengan pembuatan sabun oleh para ibu ibu PKK, dan diakhiri dengan survey pelaksanaan pelatihan. Berdasarkan hasil pelatihan didapatkan peningkatan produksi sabun mencapai 20 liter dalam satu kali produksi, serta didapatkan pula peningkatan pengetahuan dan keterampilan masyarakat dalam proses pembuatan sabun dengan mesin pengaduk.

Abstract

Aluminum alloys suffer from deficiencies in surface performance due to insufficient resistance to corrosion and mechanical qualities in harsh environments. Therefore, it is crucial to apply a protective surface modification during the manufacturing process of the aluminum component. The electroless deposited Ni-P shows great potential as a protective coating due to its simple manufacturing process and outstanding performance. This study investigates the effect of oxalic acid concentration in the anodizing process on electroless Ni-P coating. In this study, Anodic Aluminum Oxide (AAO) is formed by an anodizing process on 0.3,0.5, and 0.7 oxalic acids prior to Ni-P electroless deposition. The resulting Ni-P layer has a nodular-like morphology with a size in the order of 0.5 m or less. Moreover, the AAO surface is covered by a thin and tightly formed layer of nickel particles. The EDX analysis shows the oxygen percentage falls by up to 70% after Ni deposition in all anodizing parameters, as compared to the anodized specimens alone. In addition, the nickel content gradually decreases as the concentration of oxalic acid increases from 0.3 M to 0.7 M.

Abstract

Farmers’ skills in maintaining water pumps remain limited, although these skills are essential for sustaining agricultural production. This study is presented as a pilot study aimed at assessing the effectiveness of participatory training in improving the knowledge, skills, and attitudes of water pump mechanics. The study involved nine mechanics under the guidance of UPTD ALSINTAN Dinas Pertanian Kabupaten Bandung, each representing one of nine affiliated areas. Evaluation was conducted using pre-test and post-test instruments with 20 items on a five-point Likert scale, analyzed descriptively without inferential statistics. The initial findings indicated an increase in the overall mean score from 3.55 to 4.78, with the largest improvements observed in skills (+46.27%) and knowledge (+39,83%). These results suggest improvements in competence, although they remain exploratory. The main limitations of this study are the small sample size and reliance on self-reported measures. Further studies with larger samples and stronger designs are recommended.

Abstract

Pengeringan merupakan metode pengawetan yang digunakan untuk mengurangi kadar air pada makanan, memperpanjang masa simpan, dan menjaga kualitas produk. Penelitian ini membandingkan performa kontrol relay dan PID pada oven pengering berbasis load cell untuk mengukur kadar air buah secara otomatis sesuai Standar Nasional Indonesia (SNI). Pendekatan ini bertujuan meningkatkan efisiensi waktu dan akurasi proses pengeringan tanpa perlu penimbangan sampel secara manual. Metode penelitian melibatkan penggunaan oven pengering dengan load cell untuk membaca perubahan massa buah selama pengeringan. Arduino sebagai pengendali utama, thermocouple untuk memantau temperatur, dan mosul HX711 melalukan proses data massa. Dua skema kontrol temperatur uji relay dan PID dengan mode PI, dengan temperatur ditetapkan 105˚C. Hasil menunjukkan bahwa kontrol relay tidak mampu menjaga kestabilan temperatur akibat sifat on/off-nya yang tidak presisi. Sebaliknya, kontrol PID mode PI memberikan kestabilan temperatur dengan toleransi ±1˚C dengan rise time 2,43 menit, settling time 29,025 menit. Sistem diuji menggunakan buah mangga hingga massa stabil dengan laju penguapan rata-rata 1g/menit dan kadar air akhir mencapai 80,95%. Kontribusi penelitian ini terletak pada pengembangan sistem alat ukur kadar air berbasis evaporasi yang terintegrasi dengan load cell dan kontrol suhu otomatis, memungkinkan pengukuran kadar air secara real-time dan non-destruktif. Sistem ini berpotensi diterapkan dalam laboratorium maupun sektor industri yang membutuhkan pengukuran kadar air bahan secara efisien, presisi, dan berkelanjutan.

Abstract

Solar panels are used to convert solar energy into electrical energy. In this study it was applied to electric vehicles which have a very large potential for being constrained by shadows. In fast varying partial shading conditions, the position of the maximum power point is divided into two, namely GMPP and LMPP. This condition makes the MPPT process stuck in LMPP. Therefore, this research proposes the application of Serval Optimization Algorithm (SOA) in MPPT. This method refers to the natural behavior of the serval in nature. The fundamental inspiration of SOA is the serval hunting strategy in two stages of exploration and exploitation. The SOA is implemented in MPPT to change (duty cycle) so that it gets the best value and produces maximum solar panel output power. This SOA method was chosen to complete the partial shading conditions so that MPPT can optimally reach GMPP without going through LMPP. The solar panels used in this system are 2  units with specifications of 25 Wp with a 24V battery load and a 120W BLDC Motor compact in Electric Vehicle - Two Wheeler Scooter. MPPT SOA was tested in a simulation using PSIM and actual Software in 6 variations of normal and partial shading conditions. In the Simulation Test of Partial Shading Conditions, an average accuracy of 99.958% and an average tracking time of 0.492 seconds were obtained. SOA has a higher accuracy than PSO and GWO, which is 99.95%. And it has a faster tracking time of 0.55 seconds. In the SOC Integration Test, the SOA Method obtained an error value of 6.48% better than the GWO Method. On the Road Test with 6 condition, it can slow down the value of the decrease in battery capacity by 16.24%. The application of Single Source on the PV-MPPT-Converter can be implemented with an efficiency value of 76.86%. In previous research where SOA is a new method in Optimizing Problem Solving which has quite good accuracy performance, and in this research it can be implemented in Solar PV Optimization to track MPPT electric vehicles with varied and fluctuating partial shading conditions.
