Abstract

Pemilihan supplier yang optimal merupakan salah satu strategi bagi suatu perusahaan guna meningkatkan profit yang dimiliki perusahaan dan juga berperan dalam penentuan operasional pendistribusian CNG menuju konsumen. Dalam melakukan pemilihan dipengaruhi oleh faktor kuantitaf yang terdiri atas harga gas, kualitas gas, ketepatan waktu pengiriman dan biaya distribusi, serta dipengaruhi oleh faktor kualitatif yang terdiri atas factor-faktor subjektif perusahaan dalam melakukan pemilihan supplier. Dari setiap kriteria akan dilakukan pembobotan untuk mendapatkan indeks dari tiap kriteria. Berdasarkan metode yang digunakan terpilih dua supplier untuk membantu distribusi, adalah PT. CNG Plant, Gresik dengan 0,5 MMSCFD dan PT. CNG Plant, Pasuruan dengan 0,45 MMSCFD. Setelah melakukan pemilihan supplier tahapan selanjutnya adalah menyusun penjadwalan distribusi dengan menggunakan metode Vendor-Managed Inventory (VMI), dimana dengan menggunakan metode ini, perusahaan memiliki peran untuk mengatur jadwal distribusi gas menuju perusahaan. Dilakukan dua jenis skenario dan dua model untuk melakukan penjadwalan, dimana skenario 1 PT. Mini CNG plant, Blora mampu mendistribusikan sendiri dan skenario kedua supplier lain ikut membantu. Hasil yang didapatkan dengan menggunakan metode VMI lebih optimal dibandingkan dengan replikasi penjadwalan yang didapatkan dari hasil optimasi jangka waktu yang lebih pendek.

Abstract

Penelitian ini mengambil Terminal Jamrud, salah satu dari tiga terminal yang dimiliki Pelabuhan Tanjung Perak di Surabaya di Provinsi Jawa Timur sebagai studi kasus. Pilihan ini diambil dengan mempertimbangkan aktivitas terminal ini yang dermaga-dermaganya beroperasi terus-menerus tiada henti sehingga dapat dipastikan bahwa terminal ini sangat berkontribusi berkontribusi terhadap pencemaran lingkungan baik di wilayah perairan maupun daratannya. Analisa dilakukan terhadap kebijakan otoritas pelabuhan dan dampak dari kebijakan tersebut, termasuk teknologi yang digunakan, terhadap pengelolaan limbah padat di terminal tersebut, baik dari aktivitas kapal yang bersandar maupun kegiatan-kegiatan yang terjadi di lingkungan pelabuhan. Dari penelitian ini, dalam satu minggu saja, didapati bahwa Terminal Jamrud menghasilkan paling tidak 46,69 ton limbah padat dari kapal dan 237,74 ton dari kawasan pelabuhan. Bagaimana sebaiknya limbah padat yang dihasilkan tersebut dikelola dipresentasikan dalam makalah ini, berikut biaya yang harus dikeluarkan. Dengan pula melihat studi kasus di negara-negara lain, sejumlah simulasi dan analisa dilakukan terhadap empat jenis fasilitas pengelolaan limbah padat yang kelak dapat dipertimbangkan untuk ditempatkan di Terminal Jamrud. Kerugian dan keuntungan penggunaan masing-masing fasilitas tersebut dihitung, termasuk dalam hal efisiensi energi dan manfaat yang dihasilkan dari pengolahan limbah menggunakan fasilitas-fasilitas tersebut. Dari hasil analisa tersebut, didapati kemudian bahwa fasilitas pengomposan dan fasilitas pemisahan material spesifik dapat dipertimbangkan penggunaannya karena yang paling menguntungkan dari segi biaya yang dikeluarkan, efisiensi energi dan manfaat yang diperoleh kelak.

Abstract

Electrocoagulation is electrochemical water treatment and the simplest technology for wastewater treatment using an electrochemical cell in which the supply of DC power is applied to the electrodes made of aluminum, and the electrolyte is wastewater. The experiments were conducted using oily bilge water in an electrocoagulation batch reactor. The electrodes were aluminum with dimensions (20 cm × 8 cm × 0.2 cm) mounted at a distance of 4 cm vertically. Aluminum plate was then connected to a direct current power supply having a 220 V input and output of 10 V with electric current of 10-15 A. The total area of the effective working of the plate was 160 cm2 when was immersed at a depth of 10 cm to the solution. The deposition process was maintained constant around 30-60 minutes. The results showed that the process could reduce the turbidity from114.1 to14.3 NTU and the highest solids concentration obtained was 12.54 g/l with initial oil concentration of 50 g/l within 60 minutes. The largest oil removal of 98.75% was obtained using the initial concentration of oil 75 g/l and the lowest of 96.25% was obtained with the initial oil concentration of 150 g / l.

Abstract

Delivery cargo is a job of moving goods from the pile or a heap in the warehouse, handing it to be arranged on the vehicle and sending it to the receiving warehouse (consignee). The delivery of goods in the form of fertilizer carried out by PT. PUSRI (Pupuk Sriwijaya) at the Port of Tanjung Emas Semarang from the first line warehouse to each branch of the receiving warehouse throughout Indonesia experienced problems. The problem faced in the activities of the cargo delivery is the delay in the process of shipping goods caused by one of them by a bad warehouse inventory management system so that dwelling time is getting longer. Therefore, a good warehouse inventory management system is needed. This system has several functions, among others, as storing detailed information of goods and pointing to the location of goods. Warehouse inventory management system created with the Internet of Things was developed to track the goods / products that were previously recorded. In monitoring all information used Aduino. the web was built to provide comfort and ease in finding goods / products. With this system the cost required is low and efficient and very easy to use.

Abstract

In many cases of berth occupancy (BOR) level in the port can be one of the factors considering whether the services of port is busy or not. Later, the factors are evaluated including operational, technical or any other thing that makes this parameter to rise and affect the performance of the services of a port . In this study, the BOR assessment is applied by modeling the existing operation of an oil gas and terminal in Kalimantan using ARENA to fulfill fuel oil (BBM) and gas in the eastern part of Indonesia. The model considers various factors as the terminal service capacity and the input of terminal traffic such as increased cargo balance from time to time including ships and cargo traffic. To support the implementation of the terminal acceleration program, the analysis of utility usage dock and equipment loading - unloading (marine loading arms) is an essential item for giving arguments plans facility expansion due to the increasing traffic of ships and the cargo services through a strategic plan providing such as new facilities/equipments and other new managemet arrangement. As a result, the study may provide scenarios as options for the terminal operator to implement in achieving both the optimised throughput and acceptable BOR level by considering operational, technical, commercial and management strategies

Abstract

Dampak ekonomi dari pengembangan Pelabuhan Cartagena sangat pesat dalam kurun waktu 10 tahun terakhir. Hal ini ditunjukkan dengan adanya kenaikan Product Domestic Regional Bruto(PDRB) sektor kelautan dengan Gross Value Added(GVA) dari nilai 1,1% menjadi 3,81% dan nilai 0,1% menjadi 2,11% untuk sektor tenaga kerja. Dengan metode Regional Input-Output Tables(R-IOT) dan metode pendekatan Input-Output(I-O) didapat data dan angka – angka yang bisa memberikan beberapa terobosan pengembangan dari sektor forex pelabuhan maupun sektor pariwisata maritim, sehingga Pelabuhan Cartagena sebagai pemberi impact terbesar ke 5 dari 28 pelabuhan yang ada di Spanyol dan menempatkan Spanyol menduduki peringkat 2 dalam hal kedatangan turis dengan kapal pesiar di Eropa setelah Italia.Indonesia juga mencontoh dengan strategi yang sama sektor-sektor yang mempengaruhi PDRB,tenaga kerja pada sektor kelautan,keringanan bidang pajak, kemudahan bidang tenaga kerja, jaminan keamanan bagi investor yang menanam modalnya disektor kelautan, dengan didukung oleh akses-akses transportasi yang mudah, cepat, dan simpul-simpul kemacetan ditiadakan. Seluruh akses yang menuju kepusat-pusat ekonomi kelautan diperbaiki, industri pendukung baik dari sektor swasta maupun Badan Usaha Milik Negara(BUMN) juga berbenah. Indonesia mulai memandang laut sebagai masa depan,tidak lagi membelakangi laut, seluruh aktifitas dan kebijakannya bersifat sustainable .Potensi kelautan yang demikianlah yang dapat menjamin masa depan generasi mendatang menjadi lebih baik.
