Abstract

Setiap sumur produksi yang akan diproduksikan diharapkan fluida akan mengalir kepermukaansecara alami. Proses ini akan berlangsung sampai pada satu titik dimana tekanan reservoir akanberkurang dengan berjalannya waktu, sehingga kemampuan sumur produksi untuk mengangkatfluida ke permukaan akan berkurang atau berhenti sama sekali.Oleh karena itu dibutuhkan metodepengangkatan buatan dimana salah satunya dengan menggunakan pompa ESP. Berdasarkanpengamatan data teknik sumur BN-23, BN-35 dan BN-104 sangat cocok untuk diterapkan untukoptimasi produksi. Berdasarkan hasil perhitungan kurva IPR dengan menggunakan metoda Vogel,laju produksi maksimum (Qmaks) yang dicapai sumur BN-23, BN-35 dan BN-104 adalah masing–masing sebesar 1661 BFPD, 6446.7 BFPD, dan 1001 BFPD. Selanjutnya melalui pendekatandengan persamaan empiris didapatkan laju produksi optimum (Qo) sumur BN-23, BN-35 dan BN-104 adalah masing-masing sebesar 176 BBD, 193 BBD, 193 BBD dengan water cut masing–masing 91.2 %, 94.2% dan 84% maka dihasilkan minyak sebesar 1998 BOPD, 3333 BOPD dan1209 BOPD. Untuk mencapai laju produksi optimal sumur produksi tersebut maka disarankan padasumur BN-23 untuk mengunakan jenis pompa ESP REDA Type IND 2000 stage sebesar 119 danrange capacity 1300-2600 bfpd, Sumur BN-35 untuk mengunakan jenis pompa ESP REDA TypeING 5200 stage sebesar 119 dan range capacity 2000-3600 bfpd, dan Sumur BN-104 untukmengunakan jenis pompa ESP REDA Type IND 1300 stage sebesar 119 dan range capacity 600-1250 bfpd.

Abstract

The purpose of this study was to determine how the influence of the skills of the crew in the use of navigation equipment on the safety of the shipping fleet at PT. AL JAZEERA SHIPPING.CO.W.L.L. The population in this study is the crew of a fleet of ships on PT. AL JAZEERA SHIPPING.CO.W.L.L, amounting to 21 people from 7 ships namely Sea Monarch, Sea Thunder, Al Aali 1, Al Faisal 1, Valian Eagle, Sea Dragon, Sea Majestic. The sample used was the entire crew of PT. AL JAZEERA SHIPPING.CO.W.L.L fleet, namely Sea Monarch, Sea Thunder, Al Aali 1, Al Faisal 1, Valian Eagle, Sea Dragon, Sea Majestic, amounting to 21 people with census techniques ". Saturated sampling is done if the population is less than 100 people. Based on the analysis and discussion shows that the skills of the crew in the use of navigation equipment at PT. AL JAZEERA SHIPPING.CO.W.L.L with an average weight of 4.00 so that respondents agreed that the crew was skilled in the use of navigation equipment. Safety of the shipping fleet at PT. AL JAZEERA SHIPPING.CO.W.L.L where the average weight is 4.01 so respondents agree that the safety of the shipping fleet is good. The results of simple linear regression analysis note that the skills of the crew in the use of navigation equipment on the safety of the shipping fleet of PT. AL JAZEERA SHIPPING.CO.W.L.L is very strong and positive, besides that based on the results of the Hypothesis Testing analysis it is found that there is a very strong positive influence on the skills of the crew in the use of navigation equipment on the safety of the shipping fleet at PT. AL JAZEERA SHIPPING.CO.W.L.L.

Abstract

Cafe Jamu Iboe di Untung Surabaya menghadapi kesulitan dalam mengelola persediaan bahan baku saat menjalankan bisnisnya. Untuk menyelesaikan masalah ini, dilakukan analisis penerapan metode Ekonomi Order Quantity (EOQ) agar bisa meningkatkan efisiensi dan membuat proses produksi lebih optimal. Dengan memahami prinsip EOQ, perusahaan bisa membuat keputusan yang tepat dalam membeli dan menyimpan bahan baku. Penelitian ini menggunakan pendekatan kualitatif deskriptif, Teknik pengumpulan datanya meliputi observasi serta wawancara. Hasil penelitian menunjukkan bahwa (1) Cafe Jamu Iboe masih menggunakan cara estimasi tradisional dalam mengelola persediaan bahan baku, tanpa memperhitungkan jumlah persediaan pengaman dan titik pemesanan kembali. (2) Metode Kuantitas Pemesanan Ekonomis (EOQ) mampu meningkatkan efisiensi pemesanan bahan baku serta mengurangi risiko kekurangan persediaan. (3) Metode EOQ lebih efisien dan menghemat biaya dibandingkan sistem konvensional yang digunakan perusahaan, sehingga membantu menekan biaya pengeluaran untuk persediaan bahan baku.

Abstract

This research explores how pilotage-tug assistance, cargo-handling efficiency, and document-processing duration affect the operational performance of PT. Berkah Tata Baruna, Branch Banten. Adopting a qualitative descriptive design, the study utilized interviews, focus group discussions, and analysis of official documents to capture a wide range of stakeholder perspectives, including port authorities, shipping agents, and maritime cadets. The collected data were examined through thematic analysis and further consolidated into two evaluative measures: the Port Call Friction Index (PCFI) and the Agency Performance Score (APS). The findings indicate that shortcomings in tug services, loading-unloading productivity, and administrative procedures impose considerable limitations on agency effectiveness, even though the overall performance assessment remains generally favorable. Beyond these operational insights, the study contributes to the literature on maritime economy and sustainability by presenting practical diagnostic instruments that can be applied in similar contexts. Furthermore, it strengthens the relevance of vocational maritime education by linking theoretical learning with the realities of port operations. The results also emphasize the pressing need for stronger coordination among stakeholders, simplification of documentation workflows, and systematic training programs designed to enhance professional competence. By addressing these areas, shipping agencies and port authorities can improve service delivery, minimize delays, and foster sustainable practices that align with the broader objectives of maritime development.
