Abstract

Seiring dengan peningkatan jumlah kebutuhan energi yang ada di Indonesia, maka kebutuhan bahan bakar sebagai pemenuh kebutuhan tersebut semakin besar pula. Namun dengan semakin menipisnya jumlah ketersediaan bahan bakar minyak yang umum digunakan masyarakat, maka pemerintah mengeluarkan kebijakan pada tahun 2007 mengenai kebijakan konversi energi dari bahan bakar minyak (BBM) menjadi Liquefied Petroleum Gas (LPG). Dengan dikeluarkannya kebijakan tersebut, berdampak pada kebutuhan LPG di Indonesia yang semakin meningkat. Kebutuhan akan energi pada umumnya erat kaitannya dengan faktor pembangunan suatu daerah. Provinsi Banten yang merupakan salah satu provinsi produktif Indonesia dengan banyaknya industri besar dan laju pertumbuhan penduduk yang meningkat setiap tahunnya, menjadikan kebutuhan konsumsi energi Provinsi Banten, pada khusunya LPG menjadi semakin besar. Untuk dapat mengatasi hal tersebut, maka diperlukan adanya distribusi LPG ke Provinsi Banten. Oleh karena itu, untuk meningkatkan efisiensi distribusi, diperlukan pembangunan terminal penerima LPG yang ada di Provinsi Banten. Sehingga pada tugas akhir ini akan dilakukan desain konsep terminal penerima LPG yang berada di Pelabuhan Cigading Banten. Desain konsep yang dilakukan meliputi sistem bongkar muat, sistem penyimpanan, dan sistem distribusi. Kemudian, untuk dapat menjaga keselamatan operasional agar terhindar dari potensi bahaya yang terjadi, maka dilakukan pula proses penilaian SIL pada safety device yang ada pada sistem-sistem tersebut. Untuk dapat melakukan penilaian tersebut diperlukan adanya penentuan nilai target SIL terlebih dahulu dengan menggunakan metode risk graph, kemudian setelah mengetahui nilai target SIL akan dihitung nilai SIL dengan menggunakan fault tree analysis untuk dapat mengetahui konfigurasi safety device yang harus dipasang agar dapat memenuhi nilai target SIL. Berdasarkan perhitungan yang telah dilakukan, didapatkan hasil dari nilai target SIL dan konfigurasinya berturut-turut adalah sistem bongkar muat dengan pipa utama bernilai SIL 3 dan konfigurasi 1oo2, pipa vapour return bernilai SIL 1 dan konfigurasi 1oo1, sistem distribusi bernilai SIL 3 dengan konfigurasi 1oo2, dan sistem distribusi bernilai SIL 3 dengan konfigurasi 1oo2. Selain itu, dilakukan pula analisis keekonomian investasi terminal penerima LPG dengan memperhitungkan Capital Expenditure (CAPEX), Operational Expenditure (OPEX), Net Present Value (NPV), Internal Rate of Return (IRR) dan Payback Period (PP) dengan menggunakan skenario variasi harga yaitu $18, $18,5, $19, dan $20 serta variasi periode operasional yaitu 10 tahun, 12 tahun, dan 15 tahun. Selain itu, pada analisis sensitivitas ekonomi juga dilakukan variasi dengan penambahan CAPEX dan OPEX sebesar 5%, 10%, 20%, dan 30%. Berdasarkan perhitungan yang telah dilakukan didapatkan bahwa dari seluruh skenario memberikan hasil investasi layak dijalankan. Namun, pada perhitungan analisis sensitivitas memberikan hasil bahwa investasi yang layak dijalankan adalah investasi yang dilakukan dengan variasi periode operasional 15 tahun. ===================================================================================================== The increase in the number of energy needs in Indonesia, makes the fuel consumption become greater. fossil fuel was the most commonly used by the community to fulfill the needs of energy. To overcome the massive usage of oil fuel, as it is become rare, the government issued a policy in 2007 regarding the energy conversion from fossil fuel to Liquefied Petroleum Gas (LPG). The impact of applying the policy, makes the need of LPG in Indonesia increased. Banten which is one of Indonesia's productive provinces has many big industries and big population which increase every year, making the needs of energy consumption in Banten, especially LPG become greater. To be able to fullfill the needs of LPG in Banten, it is considered necessary to improve the efficiency of LPG distribution by designing a receiving terminal in Banten. So, this research aim to design LPG receiving terminal that located in Port of Cigading, Banten. The conceptual design of LPG receiving terminal will include the design of unloading systems, storage systems, and distribution systems. In addition, to maintain the safety factor of operating the terminal and to avoid the potential hazard that might happen, this research will also consider the SIL assessment on the safety device in every system. The assessment will include the determination of target SIL value by using Risk Graph method. After that, the value of SIL target will be calculated by using Fault Tree Analysis to know the configuration of safety device that must be installed in order to fulfill the SIL target value. Based on the calculation, the result of the SIL target value and its configuration of unloading system in the main pipe is SIL 3 with 1oo2 configuration, the vapor return pipe is SIL 1 with 1oo1 configuration, the strorage system is SIL 3 with 1oo2 configuration, and the distribution system is SIL 3 with 1oo2 configuration. This research is also provide the economic analysis of LPG receiving terminal by calculating Capital Expenditure (CAPEX), Operational Expenditure (OPEX), Net Present Value (NPV), Internal Rate of Return (IRR) and Payback Period (PP) by using price variation $ 18, $ 18.5, $ 19, and $ 20 as well as variations of operating periods 10 years, 12 years, and 15 years. In addition, the analysis of economic sensitivity is also calculated with the addition of CAPEX and OPEX by 5%, 10%, 20%, and 30%. According to the calculation has been done, all of the investment is feasible to be executed. But, in the sensitivity calculation the investment that feasible to be executed are the scenarios with 15 years of operational.
