Abstract

Kurangnya ketersediaan air bersih di Dusun Sungai Geneng, Desa Pelang, Kecamatan Kembangbahu, Kabupaten Lamongan dapat menyebabkan warga mudah terserang penyakit. Oleh karena itu, perlu diadakan acara sosialisasi kepada masyarakat untuk memperoleh wawasan tentang air bersih dan sosialisasi cara penggunaan alat filter agar dapat memakai dan mengkonsumsi air bersih dalam kehidupan sehari-hari. Beberapa acara yang dilakukan dalam kegiatan pengabdian ini, yaitu: Pertama, survei pengamatan dan analisis kondisi lapangan terhadap kondisi air sumur dan telaga yang ada di masyarakat lingkungan Dusun Sungai Geneng tersebut. Kedua, sosialisasi kepada masyarakat untuk memperoleh wawasan tentang air bersih dan sosialisasi cara penggunaan alat filter. Ketiga, pelatihan perawatan alat filter air dan tangki penampungan air bersih kepada masyarakat. Bedasarkan hasil analisis, antusias warga dalam mengikuti acara pengabdian masyarakat ini dikarenakan beberapa hal. Diantaranya adalah banyak warga yang mudah terserang penyakit karena adanya penggunaan air yang kurang bersih, kurangnya pengetahuan tentang air bersih, dan belum mengetahui cara merawat alat filter air dengan baik sehingga alat tersebut tidak mampu bertahan lebih lama dan air yang mengalir ke dalam tangki menjadi cepat kotor.

Abstract

Many areas in Indonesia still have water sources that are unsuitable for daily use. One such area is the vicinity of Sungai Geneng Mosque, Kembang Bahu District, Lamongan Regency. In this area, the water source contains high levels of lime and organic materials, making it unsuitable for consumption. To address this issue, the Corporate Social Responsibility (CSR) Team from Politeknik Perkapalan Negeri Surabaya (PPNS) implemented a water filtration application in the area. The filtration method used is the anaerobic filtration system. Based on the filtration results, high levels of lime were successfully reduced to meet health standards, making the water clean and safe for consumption. Additionally, the organic materials in the water were converted into biogas, which serves as an alternative energy source for cooking and environmentally friendly vehicles.

Abstract

Peluang terciptanya lobster air tawar sebagai komoditas perikanan semakin terbuka seiring dengan semakin populernya dikalangan pembudidaya dan konsumen, apalagi lobster air tawar ini pun mempunyai keunggulan bila dibandingkan dengan komuditas perikanan lainnya yang sudah berjalan. Usaha budidaya lobster masih ditemui beberapa kendala, diantaranya kematian akibat gagalnya proses molting, dan kematian akibat kanibalisme. Kanibalisme umumnya terjadi saat molting, hal ini terjadi karena pengerasan cangkang terlalu lambat. Sehingga pada kegiatan PkM ini diajukan kegiatan pengabdian kepada masyarakat untuk dapat membuatkan wadah atau bak kolam budidaya yang terdapat instalasi perpipaan yang mendukung serta menghemat lahan dan terdapat pencahayaan yang cukup. Pada kegiatan PkM ini dihasilkan Desain perpipaan yang digunakan pada desain perpipaan air bersih dengan peletakan pipa system pengaliran ke atas, system ini dipilih agar sirkulasi air bersih optimal pada kolam budidaya. Prototype bak pembudidaya dirancang dengan menggunakan 3 tingkat dari bahan kerangka besi hollow serta dinding terpal, hal ini dirasakan lebih sesuai dengan instalasi pada kolam budidaya yang membutuhkan lahan terbatas dan cocok digunakan untuk pembudidayaan lobster air tawar.

Abstract

Hydrogen can be utilised through a Proton Exchange Membrane Fuel Cell (PEMFC) which has many advantages, namely more energy yield, higher energy density, no emissions, and no need for recharging compared to using batteries. The highest electrolyzer efficiency results were found on the 0.05M KOH catalyst with a value of 1.70% and it can be concluded that the higher the catalyst concentration, the higher the electrolyzer efficiency. The highest power density and fuel cell efficiency quality is found in the 0.05M NaCl catalyst but with the lowest Specific Fuel Consumption (SFC) of 0.62 kg/kWh, this indicates that the relationship between concentration and power density and fuel cell efficiency is directly proportional while it is inversely proportional to Specific Fuel Consumption ( SFC). The best Break Even Ratio value is found in the NaCl catalyst type 0.05 with a value of 0.082. The use of a seawater catalyst has the highest efficient value at a percentage of 100% with electrolyzer efficiency reaching 13.36% and the lowest SFC, namely 0.24 kg/kWh. Based on these results, the use of hydrogen generators for Proton Exchange Membrane Fuel Cells (PEMFC) needs to be developed.

Abstract

RF Sputtering has been widely used as a deposition system on thin films. This study examines the impact of input power on RF voltage and self-bias voltage in an RF Sputtering system operating at a frequency of 13.56 MHz. Power variations were carried out in the range of 50 to 150 Watts to observe the changes in voltage produced during the plasma formation process. The experimental results indicate a linear dependency between power and both voltages, with a coefficient of determination (R²) above 0.9 and slope values of 2.86 and 0.96 for the RF voltage and self-bias voltage, respectively. The observed linear correlation indicates that adjusting power regulation can be utilized as an effective control parameter for both voltages, enabling the production of uniform and high-quality thin film deposition.

Abstract

This paper compares silver (Ag) and aluminum (Al) as patch materials for a microstrip dipole antenna to examine how their electrical conductivities affect electromagnetic radiation performance. Both antennas were designed with identical geometrical and substrate parameters using the Finite-Difference Time-Domain (FDTD) method, varying only the patch material. Simulation results show that the resonant frequencies are 2.4700 GHz for Ag and 2.4649 GHz for Al, with excellent VSWR values 1.0839 and 1.0836 and return loss below –27 dB. Both materials exhibit reflected power below 0.2% and have nearly identical radiated power, namely 0.3647 W for silver (Ag) and 0.3646 W for aluminum (Al). Overall, silver and aluminum demonstrate almost identical radiation characteristics. Silver offers slightly better conductivity, while aluminum provides similar efficiency at lower cost, making it a practical alternative for lightweight and economical microstrip antenna applications.
