Abstract

Crude oil gathering stations are locations where crude oil is collected before being transported to processing facilities or ports. The fire suppression system pipeline is an important component in the safety infrastructure of this station. This system is designed to detect, control, and extinguish fires quickly and effectively. In determining the pump must consider the needs of the area to be extinguished. The ring line headers (distribution pipes) or pipes surrounding the crude oil storage area must be designed, and be able to deliver the necessary water needs from the fire pump and pay attention to the economic aspects. The fire assumption designed is if one tank is burned and the other tank is cooled with water to prevent fire. The pump chosen is a centrifugal type pump and in addition a jockey pump is needed to maintain pressure in the main pipe or if the pressure drops to a certain value, the jockey pump will automatically start. The water pool to supply fire protection needs is designed to meet the minimum needs for 4 hours. Based on the design results obtained that the centrifugal pump capacity requirement is 0.148 m3 / s with a power of 25.84 kW and installed 1 pump driven by an electric motor and 1 pump driven by a diesel motor. For the main pipe size, a pipe with a nominal diameter of 12 inches with schedule 40 is needed. For the water pool in the form of roving castings with an effective volume of 4 hours.

Abstract

Indonesia has a tropical climate, which results in potentially high temperatures and humidity. This condition requires every room to have an air conditioning system to ensure comfort during activities. The air conditioning equipment used is typically an air conditioner (AC). Global warming exacerbates these conditions. On the other hand, office buildings in BSD Techno Park generally have roofs made of zinc-galvanized material coated only with aluminum foil. To maintain comfortable room temperature and humidity, heat must be removed from the room, and this heat is referred to as the cooling load. This study focuses on analyzing the cooling load of split AC units for office rooms in BSD Techno Park. The goal is to determine the total cooling load and calculate the heat removed to establish the required cooling capacity. The average office room size is approximately 80 m². Activities typically take place from 10:00 AM to 4:00 PM WIB. The calculated external cooling load is 4.042 m²/W. Thus, solar conduction through the roof (Q) is 554.04 Watts. Heat transfer through walls is 122.95 Watts, while the cooling load from glass is 118.97 Watts, from doors is 2.35 Watts, and from partition walls is 10.02 Watts. The heat generated by human activities inside the room is 2,255 Watts. Therefore, the grand total cooling load, or Effective Room Latent Heat (ERLH), is 2,558.86 Watts or 29,061.81 BTU/hr. Consequently, a split AC unit with a capacity of 2 PK and 1.5 PK, or equivalent BTU/hr, is able to meet the needs of people in a room and ensure office comfort. Abstrak: Indonesia memiliki iklim tropis sehingga berpotensi memiliki temperatur dan kelembapan udara yang sangat tinggi. Kondisi ini mengharuskan setiap ruangan memiliki sistem pendinginan udara agar nyaman digunakan untuk beraktivitas. Adapun peralatan pengkondisian udara (air conditioning) yang digunakan umumnya adalah AC. Pemanasan global membuat kondisi ini semakin parah. Di sisi lain, perkantoran yang berada di Taman Tekno BSD rata-rata memiliki atap berbahan seng galvanis yang hanya dilapisi aluminium foil. Untuk menjaga agar temperatur dan kelembapan udara ruangan berada pada kondisi nyaman, panas atau kalor harus dikeluarkan dari ruangan, dan besarnya kalor ini dapat disebut sebagai beban pendingin. Penelitian ini berfokus pada analisis beban pendingin pada AC split untuk ruangan perkantoran di Taman Tekno BSD. Tujuannya adalah untuk mengetahui total beban pendingin dan menghitung kalor yang dibuang sehingga dapat ditentukan kapasitas pendinginan udara yang diperlukan. Ukuran ruangan perkantoran rata-rata memiliki luas 80 m². Kegiatan biasanya berlangsung pada pukul 10.00–16.00 WIB. Hasil penghitungan beban pendingin luar adalah 4,042 m²℃/W. Sehingga konduksi matahari melalui atap (Q) sebesar 554,04 Watt. Perhitungan kalor melalui dinding adalah 122,95 Watt. Sementara beban dari kaca sebesar 118,97 Watt, beban dari pintu sebesar 2,35 Watt, dan dari partisi pemisah sebesar 10,02 Watt. Adapun panas akibat aktivitas orang di dalam ruangan sebesar 2.255 Watt. Dengan demikian, grand total beban pendingin atau Effective Room Latent Heat (ERLH) adalah 2.558,86 Watt atau 29.061,81 BTU/hr. Maka penggunaan AC split yang memiliki kapasitas 2 PK dan 1½ PK atau setara BTU/hr direkomendasikan karena mampu memenuhi kebutuhan dan kenyamanan manusia di dalam ruangan perkantoran tersebut.
