“…Untuk dapat memenuhi ketiga metode diatas diperlukan penelaahan data yang dipergunakan untuk menganalisis adanya indikator penuaan atau faktor risiko. Data yang dimaksud antara lain data manufaktur (gambar konstruksi, tekanan desain, temperature, umur desain (Noval & Nofirman, 2021). Spesifikasi material dsb), data servis (kandungan fluida, catatan shutdown dsb), Historis maintenance (hasil inspeksi sebelumnya, NDT report dsb) dan hasil Fitness for Services (FFS) jika tersedia.…”

Keselamatan operasi minyak dan gas bumi merupakan aspek yang sangat penting dalam proses produksi, eksploitasi dan eksplorasi, sehingga sangat perlu untuk memastikan bahwa semua elemen yang dipergunakan dapat dijamin kelayakan dan penggunaan nya. CNG Buffer Storage Tank merupakan pressure vessel yang dipergunakan untuk menyimpan fluida gas di instalasi pengolahan gas alam. CNG Buffer Storage Tank tersebut tidak memiliki data teknis yang cukup untuk menjamin keselamatan dan keamanan operasi, sehingga dalam penelitian ini akan dilakukan kajian teknis yang komprehensif untuk memastikan kondisi aman dari CNG Buffer Storage Tank. Metode yang dipergunakan dalam penelitian ini adalah metode Residual Life Assessment (RLA) yang merujuk pada standar & code dari proses fabrikasi dan aspek inspeksi yang telah dilakukan pada CNG Buffer Storage Tank. Dari hasil analisis yang telah dilakukan menghasilkan tingkat risiko dari penggunaan CNG Buffer Storage Tank masuk dalam kategori medium-high risk karena terjadi general uniform corrosion dan under deposit corrosion dengan kondisi yang wajib dilakukan de-rating dari tekanan desain awal menjadi 140 kg/cm 2 dan estimasi sisa umur layan sebesar 11 tahun sehingga CNG Buffer Storage Tank dapat beroperasi dengan batasan yang telah ditentukan.

“…The research was carried to know the performance of using refrigerants R-22, R-134a, and R-290 as a comparison material in efforts to save energy and save the environment in the future [14]. This research discusses the comparative performance analysis of 1 PK capacity cooling machines (air conditioners) using refrigerant types R-22, R-134a, and R-290 with different refrigerant filling pressure variations [15]. It is hoped that the results of this research will provide a deeper understanding of how refrigerant charging pressure affects the performance of split AC systems with variations of R22, R134a, and R290.…”

R-22 refrigerant has been recognized as a major cause of climate change and ozone layer depletion, leading to increased interest in finding more environmentally friendly alternatives. Two alternatives being considered are R-134a and R-290. The main objective of this research is to compare the Coefficient of Performance (CoP) performance of split ACs using three types of refrigerants, namely R-22, R-134a, and R-290, taking into account the environmental impact and operational efficiency. The research method involved retrofitting a 1 PK split AC which initially used R-22 with three different types of refrigerant as an experiment. The research process includes test equipment design, equipment installation, and feasibility testing before carrying out experimental testing. Tests were carried out with variations in refrigerant charging pressure of 70 psi, 75 psi, 80 psi, 85 psi, and 90 psi. The research results showed that the largest COP was found in the R-290 refrigerant, reaching a value of 0.86 at a filling pressure of 90 Psi. The largest COP value for R-22 was also found at a filling pressure of 90 psi, namely 0.66. Meanwhile, R-134a achieved the highest COP value at a filling pressure of 90 psi, with a value of 0.57 at a variation of refrigerant filling pressure of 90 Psi. In conclusion, this study provides better insight into the efficiency and environmental impact of the three types of refrigerants discussed. It also provides a useful information basis for the selection of suitable refrigerants in split air conditioning systems, with the aim of environmental conservation and achieving optimal performance

“…The natural climate in the Jakarta region is extremely hot, with temperatures ranging from 27 to 34 C, making it less comfortable in homes, workplaces, or businesses. As a result, the work ethic declines [1]. Due to this, it is necessary to have an air conditioner (AC), which works to lower the temperature of the air in a room, starting in homes, offices, hotels, and hospitals, as well as in enterprises [2] [3].…”

For urban areas and Jakarta's industrial sector, air freshener systems and air conditioners are becoming increasingly necessary. At the electronics-focused PT. CI Jakarta, the air conditioner cools the space. The goal of this research is to raise staff comfort levels and productivity levels in order to enhance output. Planning information and a cooling load analysis are needed in order to implement the cooling system in the industrial building. To determine how much AC (Air Conditioner) is required, it is important to analyze the calculation of the design of the AC (Air Conditioner) in the industrial room at PT. CI. The first step in the planning process is to identify the industrial building data, which includes the room's area and wall material as well as its contents. Analyze cooling load to calculate engine power. Choosing a cooling system and cooling. The cooling load analysis at the electronics industry building produced 712 kW of results, including a sensible load of 705.83 kW and a Latent load of 3.03 kW. The machine uses R134a as its refrigerant. 355.5 HP for the compressor. COP 2.77 is of a medium size. The central AC system was chosen as the cooling system
