Abstract

Berdasarkan hasil evaluasi pada Gedung perkuliahan E, F dan G, salah satu fasilitas yang masih minim adalah bagian proteksi kebakaran. Kondisi gedung hanya memiliki APAR yang tesebar di tiap lantai. Proteksi Kebakaran aktif seperti sistem sprinkler belum tersedia di gedung ini. Oleh karena itu, penelitian ini bertujuan untuk merancang sistem sprinkler pada Gedung perkuliahan E, F dan G. Penelitian ini memiliki tahapan pelaksanaan berupa tinjauan pustaka, Tinjauan lapangan, spesifikasi data, dan perencanaan sistem sprinkler. Untuk perencanaan sistem sprinkler, beberapa tahapan yang dilakukan adalah identifikasi tingkat bahaya kebakaran, arah pancaran sprinkler, tingkat suhu kepala sprinkler, jarak maksimum antar sprinkler, daerah yang dilindungi sprinkler, irisan antar sprinkler, luas area sprinkler, menentukan pressure, flow rate dan pressure drop, volume air untuk kebutuhan sprinkler.  Berdasarkan hasil penelitian, dibutuhkan sprinkler head sebesar 234 buah yang tersebar di 3 lantai. Dibutuhkan debit dan tekanan serta ukuran pipa pada sprinkler terjauh masing- masing sebesar 22,604 GPM, 16,293 psi, dan 1”. Pada pipa pembagi, ukuran pipanya sebesar 4”, dengan debit dan tekanan sebesar 30,883 GPM dan 30,414 psi. Volume air untuk kebutuhan sprinkler untuk 3 lantai sebesar 2779,47 galon

Abstract

As an archipelagic country with a coastline of thousands of kilometers and enormous oceans with high diversity, Indonesia has very rich fishing resources from capture fisheries. But this maritime treasure is typically under-exploited, poorly managed and vulnerable to environmentally damaging activities. Indonesia can implement effective and environmentally friendly technical solutions to prevent marine pollution. For instance, the use of Solar Power equipment (SPS) in fishing vessels can meet the energy needs of the refrigeration equipment on board. The objective of this study is to investigate the viability of solar panel installation on fishing vessels and its effects on vessel stability. The results showed that the vessel's roof is fitted with eight solar panels, each with a capacity of 500 Wp, to create 14.92 kWh per day to power five refrigeration units. Stability analysis shows that the addition of rooftop solar panels, cooling boxes, and batteries in the fish hold is in compliance with IMO Standard A.749(18) Chapter 3, ensuring the safety of the system for practical application.
