Abstract

Dalam sistem suplai dan distribusi LPG, total target, frekuensi injeksi kapal, jumlah truk, dan pengaturan tangki memiliki hubungan yang kuat untuk mencapai performansi harian. Penerimaan suplai berasal dari hasil produksi kilang dan injeksi kapal. Sedangkan, distribusi dilakukan ke SP(P)BE/agen melalui jalur kilang dan jalur depot. Produk yang disalurkan berupa unit curah dan unit tabung. Namun, penyaluran LPG dari kilang memiliki berbagai permasalahan operasional. Oleh karena itu, jalur penyaluran LPG dari kilang akan ditutup dan semua pendistribusian dialihkan ke depot. Dalam penelitian ini dilakukan pencarian kombinasi terbaik antara pengaturan total DOT (Daily of Throughput), frekuensi injeksi kapal, jumlah truk, dan waktu suplai distribusi. Hal ini bertujuan untuk meningkatkan penyaluran LPG di Depot Balongan serta melihat kemampuan maksimum tangki. Penelitian ini mengembangkan model simulasi yang meniru aktivitas suplai dan distribusi dengan menggunakan software ARENA. Simulasi dilakukan untuk meniru kondisi eksisting terlebih dahulu untuk melihat bottleneck yang terjadi. Pada kondisi eksisting terlihat bahwa pengaturan penggunaan tangki belum maksimal sehingga menyebabkan stok rendah dan lifting harian tidak seimbang untuk tiap unit yang disalurkan. Beberapa skenario hasil pengembangan total DOT, frekuensi injeksi kapal, dan jumlah truk akan dikembangkan untuk mengatasi bottleneck yang ada. Setiap skenario dievaluasi nilai performansi lifting dan utilisasi tangki. Hasil penelitian menunjukkan bahwa hampir seluruh skenario yang dikembangkan memiliki dampak signifikan terhadap kondisi eksisting. Skenario terpilih ialah skenario yang berada dalam garis frontier dan memiliki nilai performansi tinggi. ================================================================================================ In the LPG supply and distribution system, the daily target, frequency of vessel injection, number of trucks, and utilization of tank are interrelated to achieve daily performances. Supply comes from the refinery production and vessel injection. Meanwhile, distribution LPG to customers is done through the refinery unit and depot. The type of LPG that delivered is bulk and tube. However, the distribution of LPG from refinery unit has many operational issues. Therefore, distribution route from refinery unit will be closed and transferred to the depot. In this paper, the best combination between the daily target, frequency of vessel injection, number of trucks, distribution and supply time are investigated. The objective is to improve daily performances and obtain maximum tank capability. This research develops a simulation model that mimics supply and distribution activity of LPG using ARENA software. The simulation conducts to replicate the existing condition and find the bottleneck. Existing condition shows that the utilization of tank is not maximized. The daily lifting is unbalanced for each type products and tank has low inventory. Several numbers of scenario related to daily target as well as frequency of vessel injection and number of trucks are then developed to fix the existing bottleneck. Each scenario is evaluated in terms of lifting performance and tank utilization. The results shows that almost all scenarios developed have significant impacts on the existing condition. The scenario that is closer to the frontier curve and has a high performance value will be selected.
