Abstract

Padangbai Harbor is a port located in a village in Manggis District, Karangasem Regency, on the east side of Bali Island, Indonesia. Padangbai Port is a port that serves ship crossings from Bali to Lombok and Nusa Penida and vice versa serves ships heading to Bali. The Padangbai ferry port is a very busy ferry port because it has 2 routes, namely the Padangbai-Sheet route and the Padangbai-Nusa Penida route. There are 25 ships operating on the Padangbai - Selamat route, of which 2 ships belong to ASDP and 23 privately owned ships and 1 ship on the Padangbai - Nusa Penida route belongs to the Klungkung Regency Government. The Padangbai Ferry Port also has a schedule made by the Bali Class II Transportation Management Agency. However, there is a mismatch between the ship's arrival and departure times and the schedule that has been made. This research is research using qualitative methods. Based on the results of the analysis of problems in scheduling departures and arrivals at the Padangbai Ferry Port, delays of 20 minutes were still found which caused delays in the ship's onward performance. Therefore, it is very necessary to evaluate the ship's round trip time to improve performance at the Padangbai Ferry Port.

Abstract

The Merak and Bakauheni Crossing Ports are a port connection for the Merak-Bakauheni crossing which is referred to as the main bridge in connecting the islands of Java and Sumatra. Each port has various facilities that can support port operational activities, one of which is Local Port Services (LPS). Local Port Services (LPS) is a service for ship traffic that is only limited to providing information about port and terminal needs and operational data that is not responsive to shipping traffic within the coverage area of the relevant station. The feasibility of these facilities is very important for the purpose of communication with ships that will enter and exit the pier as well as supervision of the arrival and departure process of ships. The method used is an observation method so that data is obtained by making observations directly at the research location. At the Merak and Bakauheni crossing ports, there are already Local Port Services (LPS) facilities but based on the results of observations in the field, there are discrepancies with applicable regulations such as the condition of room needs and the competence of human resources needed for Local Port Services (LPS) activities. This study uses the Gap Analysis method to determine the gap between existing conditions and the Regulation of the Director General of Land Transportation Number: PR-DRJD 4 of 2021. Based on the results of the research by looking at the situation firsthand, it was found that there was a discrepancy with the Regulation of the Director General of Land Transportation Number: PR-DRJD 4 of 2021, namely trees and gangways that obstruct the indicators of free view to the water coverage area and the required human resource competencies have not been fulfilled. Efforts are made so that Local Port Services (LPS) activities can run optimally by felling trees and planning the relocation of Local Port Services (LPS) activities and involving existing human resources in various education and training activities in accordance with the required competencies.

Abstract

Berkembangnya teknologi peralatan yang menggunakan listrik, sangat dituntut adanya pengelolaandan pengawasan yang baik terhadap sarana dan prasarana elektrikal, termasuk di lingkunganpendidikan seperti Politeknik Keselamatan Transportasi Jalan, sehingga listrik yang digunakan amandan efisien. Untuk mengetahui tingkat ketersediaan operasional genset diperlukan datapenggunaan/operasional, kerusakan dan pemeliharaan genset. Kemudian dari data tersebut akandiketahui jumlah specified operating time dan actual operating time genset. Beserta data jumlahkerusakan dan waktu pemeliharaan, maka data ini selanjutnya digunakan untuk menghitung MeanTime Between Failures (MTBF) dan tingkat reliability (keandalan) genset. Dengan data yang samajuga dapat diperoleh tingkat availability (ketersediaan) genset. Dimana hasil analisis menunjukkanbahwa genset di Politeknik Keselamatan Transportasi Jalan memiliki kondisi yang jarang mengalamikerusakan/gangguan (ditandai dengan tingkat reliability dan availability ≥ 95%). Sedangkan hasilanalisis untuk maintenance (pemeliharaan) yang diketahui melalui nilai Mean Time To Repair(MTTR), dihitung menggunakan rasio durasi waktu kerusakan dibandingkan dengan frekuensikerusakan, dimana hasil perhitungannya yaitu 1,60 jam. Artinya dibutuhkan waktu yang relatif singkatyaitu 1,60 jam untuk genset dapat beroperasi kembali setelah mengalami kegagalan.
