Abstract

Rescue operations onboard marine vessels rely on effective and reliable deployment mechanisms for rescue boats, particularly in emergency scenarios. Cranes are commonly installed to assist in lowering rescue boats, but their performance depends greatly on the strength and reliability of their mounting systems. This study investigates the structural performance of a rescue boat crane mounting system on an LCT 153 vessel using finite element analysis. The problem addressed in this research is the lack of quantitative data on how different crane configurations affect the structural integrity of their mounting base under operational loads. Two crane models with different outreach and load specifications were assessed to identify the most structurally efficient option. Stress distribution and deformation were simulated using 3D models and meshed at various sizes to ensure convergence accuracy. The results revealed that the configuration with a 6-meter outreach generated lower stress (19.69 MPa) and deformation (0.004 mm), while the 7-meter alternative showed higher values. The findings contribute to safer and more efficient crane mounting designs and serve as a reference for shipyards in selecting appropriate equipment based on load performance and structural reliability.

Abstract

Ketersediaan air bersih merupakan masalah krusial di Dusun Puripan. Kondisi geografis dusun pada dataran rendah menyebabkan sumber air tanah sulit didapatkan. Akibatnya, masyarakat bergantung pada air hujan yang ditampung di Waduk. Air Waduk ini memiliki kualitas yang buruk, yaitu keruh dan berbau, sehingga tidak memenuhi standar kesehatan dan kebersihan yang ditetapkan oleh Peraturan Menteri Kesehatan No. 32 Tahun 2017. Program Pengabdian Masyarakat ini bertujuan untuk meningkatkan kualitas air dari Waduk agar layak digunakan untuk kebutuhan sehari-hari. Metode yang diterapkan meliputi tiga tahap. Pertama, Persiapan, berupa survei lokasi dan kualitas air serta penentuan titik pemasangan alat. Kedua, Sosialisasi, untuk memberikan wawasan tentang pentingnya air bersih sesuai standar. Ketiga, Pemasangan Alat Filtrasi PVDF Membrane with Lining 5000 L pada sistem perpipaan, yang ditempatkan di antara pompa dan tandon. Hasil kegiatan menunjukkan antusiasme tinggi dari warga yang didorong oleh tingginya kasus penyakit akibat air kotor. Pemasangan alat filtrasi berbasis teknologi PVDF Ultrafiltrasi (UF) Membrane berhasil menyaring air Waduk yang keruh menjadi air bersih sebelum didistribusikan ke rumah-rumah. Program ini berhasil terlaksana dengan sukses, meskipun terdapat kendala akses geografis. Diharapkan program ini dapat meningkatkan penggunaan air bersih, mengurangi risiko penyakit, dan menjadi model solusi bagi daerah lain yang menghadapi masalah air serupa.
