Abstract

Keterbatasan akses air tawar akibat intrusi air laut dan abrasi menjadi permasalahan krusial bagi masyarakat pesisir yang belum terjangkau infrastruktur pengadaan air bersih. Salah satu solusi inovatif untuk mengatasi masalah ini adalah penerapan Fresh Water Generator (FWG) berbasis panas matahari. Penelitian ini mengusulkan pemanfaatan teknologi Concentrated Solar Power (CSP) dengan desain Cavity Receiver sebagai Heat Plate pada sistem FWG, yang dirancang untuk memaksimalkan area penyerapan radiasi surya. Penelitian ini bertujuan untuk menganalisis pengaruh ketebalan material dan kecepatan aliran fluida kerja terhadap kinerja termal Cavity Receiver. Evaluasi terhadap koefisien perpindahan panas menyeluruh dari berbagai variasi desain dilakukan menggunakan metode simulasi Computational Fluid Dynamics (CFD). Hasil simulasi menunjukkan bahwa variasi ketebalan material dan kecepatan aliran secara signifikan memengaruhi tekanan dan suhu kerja fluida. Konfigurasi paling optimal dicapai pada desain Cavity Receiver dengan ketebalan material 1 mm dan kecepatan aliran fluida sebesar 0,05 m/s, yang mampu menghasilkan suhu fluida hingga 54°C. Kesimpulannya, optimasi pada parameter desain tersebut secara langsung meningkatkan performa Heat Plate dan berdampak pada peningkatan efisiensi termal sistem FWG secara keseluruhan.   The limited access to fresh water due to seawater intrusion and abrasion has become a crucial problem for coastal communities unreached by clean water supply infrastructure. An innovative solution to address this issue is the application of a solar-powered Fresh Water Generator (FWG). This study proposes the utilization of Concentrated Solar Power (CSP) technology with a Cavity Receiver design as the Heat Plate in the FWG system, which is designed to maximize the solar radiation absorption area. This research aims to analyze the effect of material thickness and working fluid flow velocity on the thermal performance of the Cavity Receiver. The evaluation of the overall heat transfer coefficient from various design variations was conducted using the Computational Fluid Dynamics (CFD) simulation method. The simulation results indicate that variations in material thickness and flow velocity significantly affect the pressure and working temperature of the fluid. The most optimal configuration was achieved in the Cavity Receiver design with a material thickness of 1 mm and a fluid flow velocity of 0.05 m/s, which is capable of producing a fluid temperature of up to 54°C. In conclusion, the optimization of these design parameters directly improves the Heat Plate's performance and contributes to the enhancement of the overall thermal efficiency of the FWG system.

Abstract

Keterampilan masyarakat nelayan di Pelabuhan Cituis, Desa Surya Bahari, Kabupaten Tangerang, dalam menangani potensi bahaya kebakaran pada kapal tradisional. Kapal nelayan tradisional di wilayah ini memiliki risiko kebakaran yang tinggi akibat penggunaan bahan bakar minyak (BBM), aktivitas memasak di atas kapal, serta kondisi mesin yang sering kali sudah tua dan tidak terawat. Masalah utama yang dihadapi adalah rendahnya kesadaran nelayan akan prosedur keselamatan dan minimnya ketersediaan Alat Pemadam Api Ringan (APAR) di atas kapal. Metode yang digunakan meliputi penyuluhan teoretis mengenai penyebab dan pencegahan kebakaran, sesi tanya jawab interaktif, serta praktik simulasi pemadaman api menggunakan APAR yang dipandu oleh para cadet mahasiswa. Hasil kegiatan menunjukkan adanya peningkatan pemahaman peserta yang signifikan mengenai langkah-langkah darurat dan cara pengoperasian alat pemadam kebakaran. Melalui pelatihan ini, nelayan kini merasa lebih percaya diri dan proaktif dalam menjaga keselamatan diri serta aset kapal mereka selama beroperasi di laut.   This community service activity aims to improve the knowledge and skills of the fishing community at Cituis Port, Surya Bahari Village, Tangerang Regency, in handling potential fire hazards on traditional ships. Traditional fishing vessels in this region carry a high risk of fire due to the use of fuel oil (BBM), cooking activities on board, and the condition of engines that are often old and poorly maintained. The main problem faced is the low awareness of fishers regarding safety procedures and the minimal availability of fire extinguishers (APAR) on board. The methods used include theoretical counseling on the causes and prevention of fires, interactive Q&A sessions, and fire-fighting simulation practices using fire extinguishers guided by student cadets. The results of the activity showed a significant increase in participants' understanding of emergency steps and how to operate fire-fighting equipment. Through this training, fishers now feel more confident and proactive in maintaining their personal safety and ship assets while operating at sea.

Abstract

Sistem kelistrikan pada perahu nelayan mendukung pengasutan mesin, penerangan, navigasi, komunikasi, dan keselamatan operasi. Kegiatan PkM ini bertujuan memperkuat pengetahuan dasar, keterampilan pemeriksaan, dan kesadaran keselamatan kelistrikan pada nelayan Desa Sukawali. Program dilaksanakan pada 10 Desember 2025 di Politeknik Pelayaran Banten dan diikuti 20 nelayan pengguna kapal motor kecil. Pendekatan andragogi partisipatif memadukan penyuluhan teori, praktik penggunaan multimeter, pemeriksaan koneksi, terminasi kabel tahan air, pengenalan proteksi arus, dan simulasi penanganan korsleting. Evaluasi menggunakan pre-test/post-test, pengamatan keterampilan, dan indikator kesadaran keselamatan. Kehadiran mencapai 100%; pemahaman dasar kelistrikan meningkat secara deskriptif dari 40% menjadi 85%, keterampilan praktik mandiri mencapai 75%, dan kesadaran keselamatan mencapai 90%. Instrumen item-level, formula skoring, data individual, dan uji inferensial tidak tersedia, sehingga angka tersebut diperlakukan sebagai capaian deskriptif, bukan bukti signifikansi statistik. Program memberikan pengalaman praktis pemeliharaan preventif, sedangkan retensi keterampilan dan perubahan kondisi kelistrikan kapal setelah kegiatan belum dievaluasi.   Electrical systems on fishing boats support engine starting, lighting, navigation, communication, and operational safety. This community service program aimed to strengthen basic knowledge, inspection skills, and electrical-safety awareness among fishers in Sukawali Village. The activity was conducted on 10 December 2025 at Politeknik Pelayaran Banten and involved 20 small-motor-boat fishers. A participatory andragogical approach combined interactive theory, multimeter practice, connection inspection, water-resistant cable termination, overcurrent protection, and short-circuit emergency simulation. Evaluation used pre-test/post-test, practical-skill observation, and safety-awareness indicators. Attendance reached 100%; basic electrical understanding increased descriptively from 40% to 85%, practical inspection skills reached 75%, and safety awareness reached 90%. Item-level instruments, scoring formulas, individual data, and inferential tests were unavailable, so these figures are treated as descriptive program outcomes rather than evidence of statistical significance. The program provided practical exposure to preventive maintenance, while skill retention and post-program changes in onboard electrical conditions remain unevaluated.

Abstract

Keandalan akumulator penting bagi pengasutan mesin, lampu navigasi, komunikasi, dan perangkat navigasi pada perahu nelayan skala kecil. PkM ini bertujuan memperkuat kapasitas nelayan Desa Kohod dalam pemeriksaan dan perawatan preventif akumulator. Kegiatan dilaksanakan pada 14 Juli 2026 dengan sasaran 20–30 perwakilan nelayan; jumlah hadir final belum tercatat secara konsisten sehingga rentang tersebut diperlakukan sebagai sasaran program. Program menggunakan Participatory Action Research dengan strategi andragogi dan komposisi 30% teori serta 70% praktik, meliputi pengukuran tegangan menggunakan multimeter, pembersihan/proteksi terminal, dan pengukuran massa jenis elektrolit. Evaluasi menggunakan pre-test, post-test, dan uji unjuk kerja. Capaian agregat menunjukkan pemahaman teknis minimal 80% untuk tegangan, massa jenis elektrolit, dan state of charge; namun data individual, skor rata-rata, standar deviasi, dan rubrik uji keterampilan tidak tersedia. Program menyediakan modul saku dan pocket multimeter/kit servis aki serta merancang monitoring satu dan tiga bulan. Hasil mendukung manfaat praktis pelatihan, tetapi dampak jangka panjang terhadap frekuensi kerusakan dan availability sistem belum diukur.   Accumulator reliability is important for engine starting, navigation lights, communication, and navigational devices on small fishing boats. This community service program aimed to strengthen the capacity of fishers from Kohod Village to inspect and maintain accumulators preventively. The activity was conducted on 14 July 2026 with a target of 20–30 fisher representatives; final attendance was not recorded consistently, so this range is treated as the program target. The program used Participatory Action Research with an andragogical strategy and a 30% theory/70% practice composition, including voltage measurement with a multimeter, terminal cleaning/protection, and electrolyte specific-gravity measurement. Evaluation involved pre-test, post-test, and practical skill assessment. Aggregate outcomes showed at least 80% technical understanding for voltage, electrolyte specific gravity, and state of charge; however, individual data, means, standard deviations, and the skill-test rubric were unavailable. Participants were provided with a pocket guide and a pocket multimeter/battery-service kit, while one- and three-month monitoring was planned. The findings support the practical value of training, but long-term effects on battery failures and electrical-system availability remain unmeasured.
