Abstract

PT TPS Surabaya is a company engaged in terminal handling, especially containers. In carrying out operational activities to transport containers from the dock to the company's container yard, it uses eighty head truck fleets. Operational activities for transporting containers are carried out 24 hours a day so that maintenance is needed. Therefore, the operational head trucks do not experience sudden damage and disrupt operations. The malfunction of the device can occur due to damage to the components in the device. The design of the component replacement and the inspection intervals on the components is needed to avoid sudden component damage. Calculation of interval replacement and component checking is done by calculating the damage distribution followed by searching for index of fit and goodness of fit using Minitab software. The result showed that the inspection time interval of 1091 hours for the air system and 398.45 hours for the transmission system components. Besides, the replacement time interval for the component of the air system is 62 hours and the transmission system is 124 hours after inspection.

Abstract

Freight forwarding is a logistics company which provide land delivery services rely heavily on trucking vendors. The available trucking vendors may not fulfill the company's expectations. Therefore the research was conducted to analyze the performance, selection process, management and development of 26 trucking vendors. The research began with the formation of a Critical Success Factor (CSF) and its development, namely a Key Performance Indicator (KPI) in accordance with company objectives. Then the CSF and KPI was weighted through the Analytic Hierarchy Process (AHP) method, determined the optimal performance value of each KPI, measured the performance of each vendor through the scoring method, analyzed the performance of the trucking vendor that was not optimal through Root Cause Analysis (RCA) by looking for the cause based on fishbone diagrams and FMEA tables, as well as providing suggestions regarding the management and development of trucking vendors. The results of the study were 11 CSFs and 28 KPIs that were formed. Based on the selection process conducted on 26 trucking vendors, there are 3 excellent vendors, 4 very good vendors, 11 good vendors, 3 matching vendors, and 5 unsatisfactory vendors. Furthermore, researcher conducted root cause analysis (RCA) of vendor representatives “matching” and “unsatisfactory” categories with fishbone diagrams and FMEA tables. Where the 5 highest RPN values from the FMEA table were given suggestions for improvement. Meanwhile, the excellent, very good, and good vendor categories are developed through strategic plans for the future.

Abstract

The coast is an area that has potential for tourist attractions, including for turtle conservation which is relied on as a support for the economy. Turtles are one of the protected animals, not just protected by law because they are feared they will become extinct. The Turtle Conservation "Pearl of the Masaran Sea" which is located on Sumbreng Beach, East Java, is one of the turtle conservation areas developed by the Trenggalek Lentera Society. Activities carried out at the turtle conservation site "Pearl of the Masaran Sea" include relocating turtle eggs, caring for turtle eggs, combing eggs, and also releasing hatchlings. There are 5 types of turtles that are protected on Sumbreng beach, some of which are green turtles and hawksbill turtles which are included in the Appendix I category, which means they are prohibited from being traded internationally. Apart from visiting tourists being able to see the turtle breeding process, this conservation also provides economic tourism such as small Jeep facilities that are used to get around the beach and releasing hatchlings in certain months. However, due to lack of exposure to this conservation area. This resulted in a small number of tourists coming, and also some tourists coming in the wrong month and not being able to see the hatchlings being released onto the beach. Therefore, this service presents an innovation in the form of a website facility that is useful for updating all activities taking place at the "Pearl of the Masaran Sea" Turtle Conservation. So it can attract more tourists to visit this tourist attraction and tourists can also find out which months are effective for visiting this tourist attraction. It is hoped that the "Pearl of the Masaran Sea" turtle conservation will have the potential for educational tourism which can be developed further, so that it can support the economy of the surrounding community and can also be used as a source of income for managing the turtle conservation itself.

Abstract This paper explores arbitration dispute resolution methods and the readiness of arbitration institutions to address challenges arising in the digital economy. The research method employed is normative legal research with a conceptual approach. The concept of the digital economy is delineated using two approaches, depicting its influence on various sectors and identifying emerging business models. There are three types of businesses in the digital economy: e-commerce, payment services, and other business models such as app stores and electronic advertising. It is found that disputes in the digital economy exhibit specific characteristics, notably involving third parties in transactions, standardized electronic contracts, and the complexity of information technology systems. Dispute resolution in this context considers the choice of dispute resolution forum, applicable laws, as well as the use of online technology and expeditious arbitration procedures. Additional challenges include enhancing arbitrator capacity and complete digitization of the arbitration process. Abstrak Tulisan ini akan mengeksplorasi metode penyelesaian sengketa arbitrase dan kesiapan institusi arbitrase dalam menghadapi tantangan yang muncul dalam ekonomi digital. Metode penelitian yang digunakan adalah penelitian hukum normative dengan pendekatan konseptual. Konsep ekonomi digital dijelaskan dengan dua pendekatan, menggambarkan pengaruhnya pada berbagai sektor, dan mengidentifikasi model bisnis yang berkembang.

Abstract

Single Point Mooring (SPM) is a system used to connect tankers with offshore installations to move oil or gas from ships to land. Therefore, SPM must be able to operate in good condition by carrying out routine maintenance. Surabaya Shipyard often receives requests for SPM repairs, but the risk level is often at a dangerous risk. This study aims to determine the right mitigation in overcoming the risk of SPM overhaul using the Failure Mode and Effect Analysis (FMEA) method to get the highest risk (RPN) and the Fault Tree Analysis (FTA) method which is useful for determining the factors that cause damage to the system. Based on the results of the study, 5 top events were obtained which were the priority risks in the overhaul process. From the 5 top events, 14 basic events were obtained which were the root cause of the failure of the SPM overhaul and mitigation must be carried out immediately so that the risk can be overcome and does not cause losses to Surabaya Shipyard.
