Abstract

This study simulated Proton Conducting Solid Oxide Fuel Cell (pSOFC) – Micro Gas Turbine (MGT) hybrid system on three different configuration. The first configuration use bypass hot gas from combustor going to fuel heater without  pass the turbine first. The second configuration use bypass hot gas out of turbine going to fuel heater. The third configuration is combined bypass out of combustor and also bypass out of turbine. The performance of these system are analyzed by using variation of operating pressure, fuel utilization (Uf), steam to carbon ratio (S/C), and bypass valve. Moreover, the impact of different bypass position were also evaluated. The result shows that the efficiency of using a double bypass hot gas flow after combustor and turbine is about 67%. This configuration became the best one among of another two configuration which proposed in this research.  The utilization of heat by using a double bypass hot flow gas after turbine and combustor has proven more effective to increase the system efficiency. Means that it can reduce the heat losses of the system.

Abstract

This research proposes a new model of overlap and helix blade shape. The overlap shape of the blades gives room to the air flow shortly after pounding the blades. Air flow direction is strived to be able to push the next blade so that the process of the turbine blade rotation becomes more effective. While the helix model is expected to produce a more efficient turbine rotation due to its multilevel shape. The wind speeds tested were 2 m / s, 4 m / s, and 6 m / s. Turbine speed rotation data retrieval is carried out at each additional time. The overlap blade has a greater angular velocity value of 9.4 rad / s at 2 m / s wind speed, 21.9 rad / s at 4 m / s wind speed, and 29.8 rad / s at 6 m / s wind speed.Turbines with multilevel helix blades have a higher level of stability compared to overlap blades. This is because there are two levels of turbine blades which have an angle difference of 600 which can receive more stable wind collisions. However, due to the smaller cross-sectional area of the helix blade turbine (ie 50% of the overlap blade) the effective impact area on the blade is also getting smaller. So that the energy that can be converted is also relatively smaller than the overlapping blade.

Abstract

The prevalent manual method of replacing ceiling lamps, which often involves climbing on unstable furniture, poses significant safety risks, including potential falls, electrocution, and other severe injuries. This common practice underscores an urgent need for safer and more efficient lamp maintenance solutions in both domestic and commercial settings. This research aims to mitigate these inherent dangers by developing and upgrading conventional ceiling lamp changers into a semi-automatic system. The primary objectives are to enhance the safety, speed, and overall ease of the lamp replacement process, thereby effectively minimizing the risk of user injury. The proposed methodology involves designing a semi-automatic ceiling lamp changer by integrating a control switch mechanism that enables remote rotation of the lamp holder. This innovative approach will facilitate the safe removal and installation of lamps without direct manual contact or the necessity of climbing. Concurrently, comprehensive product cost planning and market-driven pricing strategies will be conducted to ensure the device’s affordability and widespread community acceptance. The successful development of this semi-automatic ceiling lamp changer is anticipated to provide a significantly safer, faster, and more convenient alternative for lamp replacement. This remote-operated design is expected to substantially reduce injury incidents associated with current manual methods. By ensuring affordability and market compatibility, this innovation aims to achieve broad community adoption, ultimately contributing to safer environments for lamp maintenance.

Abstract

The Community Service (CS) program took place in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, approximately 100 km southwest of Malang City. The target group for this program includes small and medium enterprises (SMEs) engaged in koi fish spawning. Our partners face several challenges, primarily the reliance on aeration pumps powered by the national electricity grid (PLN) to supply oxygen to the ponds. The program aimed to install a 100 Wp solar panel system to generate clean energy for a low-voltage aeration pump, helping to maintain optimal oxygen levels in the pond and supporting healthy fish growth. The program successfully implemented this solar-powered aerator pump system in the pond area, providing an innovative, sustainable solution that empowers the community by integrating science and technology into fisheries. It is hoped that this program will inspire other fish farmers in Tulungagung and surrounding areas to adopt similar sustainable practices.

Abstract

Limbah pohon pisang yang meliputi batang pohon memiliki potensi pemanfaatan yang beragam, diantaranya dapat digunakan menjadi struktur material pada bahan bangunan salah satu diantaranya adalah cladding. Pada penelitian ini dibuat komposit menggunakan serat alam (batang pisang) menggunakan berbagai jenis resin polimer dan diuji kekuatan tariknya yang nantinya akan dibuat menjadi struktur cladding. Cladding merupakan salah satu teknik dalam konstruksi dengan mengaplikasikan material yang berbeda-beda dengan tujuan membuat suatu lapisan. Sampai saat ini material yang biasa digunakan sebagai cladding adalah kayu, vinyl, batu veneer dan logam. Komposit mulai digunakan sebagai bahan alternatif pengganti struktur cladding dengan  memanfaatkan serat alam dalam hal ini adalah batang pohon pisang sebagai bahan alternative pengganti material cladding pada umumnya. Penelitian ini mengevaluasi sifat mekanik komposit serat alam berbahan baku batang pisang dengan matrik resin poliester dan epoxy melalui uji tarik. Komposit dibuat dengan tiga variasi fraksi volume serat yaitu 30%, 50%, dan 70% untuk mengetahui pengaruh kadar serat terhadap kuat tarik komposit. Hasil uji tarik menunjukkan bahwa peningkatan fraksi volume serat berbanding lurus dengan peningkatan tegangan tarik komposit. Pada fraksi volume serat 30%, tegangan tarik maksimum yang diperoleh sebesar 10,3 MPa, sedangkan pada fraksi volume 50% meningkat menjadi 13,9 MPa. Tegangan tarik tertinggi dicapai pada fraksi volume serat 70% dengan nilai sebesar 19,0 MPa.
