Abstract

Banyuwangi merupakan kabupaten dibagian paling timur pulau jawa yang terkenal dengan destinasi pariwisata sebelum pandemi covid19, namun pandemi membuat kegiatan pariwisata terpuruk. Pada tahun 2023 ini, Banyuwangi mulai bangkit kembali kegiatan pariwisatanya karena ditunjang oleh menggeliatnya pelaku UMKM yang turut bangkit. UMKM sangat berperan penting dalam pemulihan perekonomian pasca pandemi, oleh sebab itu program - program  terkait UMKM banyak dicanangkan pemerintah pusat dan daerah yang antara lain perijinan, sertifikasi halal dan sebagainya. Namun tidak semua program menyentuh kebutuhan dari UMKM, salah satunya UMKM POKLAHSAR PEPAYA yang berada di Desa Pesucen Kecamatan Kalipuro, Kabupaten Banyuwangi. UMKM ini masih banyak mengalami kendala yang antara lain  permasalah kemasan yang masih sangat sederhana sehingga kurang menarik bagi konsumen. Program Pengabdian Kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan penjualan mitra dengan memperbaiki kualitas kemasan. Kegiatan PKM ini melibatkan mitra, dosen dan mahasiswa Jurusan Teknik Mesin dan Prodi Teknologi Pengolahan Hasil Ternak. Metode kegiatan pengabdian ini adalah melakukan survey untuk mengidentifikasi permasalahan yang dihadapi oleh mitra dan melakukan studi literatur untuk mendapatkan solusi atas permasalahan mitra. Setelah solusi permasalahan mitra didapatkan, langkah selanjutnya melakukan desain kemasan yang menarik guna meningkatkan penjualan produk beserta dengan mesin band sealernya. Hasil dari kegiatan PKM ini adalah kemasan produk yang sangat menarik sehingga dapat meningkatkan jumlah konsumen yang membeli produk dan omzet penjualan meningkat, yang pada akhirnya berimbas terhadap peningkatan kesejahteraan mitra yang beranggotakan Ibu - Ibu rumah tangga.

Abstract

Study This aim For designing construction addition and analysis strength elongated floating dock 6000 TLC as access repair boat use Finite Element Method (FEM). Problems found is ratio long a floating dock that doesn't sufficient when repair carried out on ships with 60 to 80 meters long, so worker difficulty working in parts tall bow and stern. For overcome problem this, design construction addition done with three variation long, that is 8 meters, 10 meters and 12 meters. Analysis results show that construction addition increase accessibility worker For repair ship on the part bow and stern. From third testing strength elongated show that construction addition capable withhold burden addition without exceed voltage permits set by American Bureau of Shipping (ABS). Voltage flexible maximum is 42.35 MPa for 8 meters variation, 59,741 MPa for 10 meters variation, and 71,486 MPa for 12 meters variation, meanwhile voltage shift maximum is 20,709 MPa for 8 meters variation, 29,038 MPa for variation of 10 meters, and 34.93 MPa for 12 meters variation. All variation own factor safety more big of 1, so structure stated safe For used. Keywords : ABS, Design, FEM, construction, stress

Abstract

Tugboats play a crucial role in supporting the safety and operational efficiency of ports and offshore activities. One of the key components in tugboat design is the skeg, which serves to enhance directional stability and reduce yawing effects. This study aims to analyze the influence of the number of holes in the skeg on the flow characteristics and resistance of a tugboat. Three skeg variations were tested: a skeg without holes, a skeg with two holes, and a skeg with four holes, under two speed conditions, namely 10 knots and 15 knots. The observed parameters include wetted surface area, drag force, and longitudinal flow velocity (velocity u). The simulation results indicate that the skeg without holes produced the lowest drag values, at 22.570 N at 10 knots and 138.430 N at 15 knots, along with a more stable and streamlined flow pattern. In contrast, adding holes to the skeg resulted in increased drag and flow disturbances in the form of vortices and fluid separation. Therefore, the skeg without holes is considered more hydro dynamically optimal for improving the operational efficiency of tugboats.
