Abstract

A minimalist platform is a platform with a smaller and simpler deck and has less equipment. Minimalist platforms are generally designed for fields with lower reservoir reserves and are expected to have low costs in terms of fabrication and installation. One of the studies in developing a minimalist platform is about a conductor pipe that functions as a well and as the leg of the platform. This platform is susceptible to deflection under lateral and axial loads. In this research, an analysis will be carried out on the conductor pipe as a single pile which is subjected to a combination of lateral and axial loads to determine the stress and deflection that occurs in the conductor leg. This study was conducted using the finite element method with ABAQUS software. Inclination variations were carried out to determine the strength of the conductor leg when an inclination occurs. The result of this study was found that the conductor leg with an inclination of up to 1.5 degrees still had a stress below 0.6 yield. The result of this analysis shows that the conductor leg’s stress increases with increasing inclination. The maximum stress occurs at 1.5o of inclination which is 82.45 MPa under operating conditions and 125.45 MPa under extreme conditions. This stress is still below the allowable stress of 213 MPa (0.6 yields).

Abstract

The aim of this study is to determine the time required in the evacuation of the passengers KL. Sultan Hasanuddin when it experienced a fire based on IMO regulations. Data from the National Transportation Safety Committee (KNKT) shows that 221 shipping accidents were investigated during 2007-2023. The majority of accidents are classified as ships on fire (33 percent) with one of the biggest handling focuses on passenger ships and most of the accidents resulted in fatalities, so it is necessary to provide input and information regarding the evacuation of passengers and cadets regarding the process and time of evacuation when the ship experiences a fire. The type of research is quantitative research using pathfinder software simulation whose evacuation route is based on safety plan data fo KL. Sultan Hasanuddin. From the simulation results and analysis obtained the time required in evacuating passengers KL. Sultan Hasanuddin when experiencing a fire based on the provisions of IMO MSC.1/Circ.1238 in night conditions is 25.44 minutes and in daytime conditions 24, 43 minutes, which is faster during the day due to the distribution of passengers on the deck which reduces the density on the evacuation route. The alternative evacuation route on the main deck is 24% faster than the evacuation route planned in the Safety Plan, thus providing an opportunity for passengers to evacuate faster and avoid fire smoke.

Abstract

Technology in the construction sector is increasingly developing and advancing at this time. The construction that we often encounter is steel construction. In steel construction, we most often encounter metal joining or welding processes. Shield Metal Arc Welding (SMAW) is a metal joining process that uses electrical energy as a source of heat and is assisted by electrodes. In this journal, I modeled the welding results using Ansys Workbench. The modeling aims to carry out a tensile test simulation to determine the tensile strength of SS400 Steel with a plate thickness of 8 mm, 10 mm, and 12 mm. This research began with creating a model in ANSYS by referring to the SNI 8389:2017 standard. After the modeling is complete, then input the materials to be used, mesh the model with a size of 2 mm, and determine the fixed support and force of 100,000 (N/m2). Then we carried out a tensile test simulation to get the normal stress and total deformation values. The largest normal stress value was obtained on the 8 mm plate, which was 3845.4 MPa and the largest total permit value was obtained on the 8 mm plate, which was 0.28271 mm. The conclusion from this test is that the smaller the cross-sectional area of a model, the higher the pressure it will experience, so it will experience higher stress and will experience cooling more easily.

Abstract

In the era of rapid digitalization, technology allows fast access to information via the internet. Digitalization of information systems is important to increase organizational efficiency. In the port sector, the Harbormaster's Office and the Tanjung Perak Surabaya First Class Port Authority have used Inaportnet to support shipping activities. One of the main services is the Sailing Approval Letter (SPB) which has been digitized in the Inaportnet SPS system. However, information dissemination by duty officers is still limited to WhatsApp groups and personal communications, causing inefficiencies. This research aims to evaluate the development and integration of an online guard officer information system using PHP. This research was carried out using the research and development method using a prototype model. Testing was carried out using the black box method with results showing a 100% functionality success rate. This integration produces additional features such as the main page, guard officer information dashboard, admin login and logout menus, as well as information notifications that can be used on all platforms. The research results show that this system increases operational effectiveness and efficiency at the Harbor Master of Tanjung Perak Surabaya. It is hoped that these findings can become a reference for the development of information systems in the maritime sector and increase understanding in data management.

Abstract

The need for ocean data is important to increase the utilization of ocean areas. A facility, development, system, or structure in the ocean cannot be planned properly without data in that ocean. One of the important data in water areas is ocean waves. In the offshore area of Pesisir Barat, wave characteristic data is still very hard to find. Knowledge of the ocean characteristics of the Pesisir Barat waters is needed, one of which is in the form of wave characteristics. To obtain more comprehensive information, two satellite reanalysis data sources were analyzed. The average height of significant wave height in the Perisir Barat is 1.75 to 2.25 m from BMKG and only 0.25 to 1.00 m from ECMWF. Based on the wave direction, the ocean waves in the Pesisir Barat move North to Northwest (NW), perpendicular to the coastline. The distribution of the annual maximum significant wave height matches the theoretical Log-normal distribution. Extreme significant wave height is obtained with a value of 4.10 to 4.29 m for a 100-year return period and 3.09 to 3.39 m for a 1-year return period. In terms of design or study of maritime potential in the western waters of Lampung, these values can be a benchmark as a basic study of wave characteristic data.

Abstract

This research aims to analyze the vulnerability to tsunami disasters in Mamuju District, West Sulawesi, using remote sensing technology and Geographic Information Systems (GIS). Mamuju District is at high risk of tsunamis due to its coastal location and its position between active tectonic plates. The analysis utilizes five main parameters: elevation, slope gradient, distance from rivers, distance from the coastline, and land cover. The GIS overlay analysis method is applied to map tsunami hazard zones, combining weighting and scoring for each parameter. The results indicate that 3% of the area has very high vulnerability, 7% of the area has high vulnerability, while 82% of the area has low to very low vulnerability. Areas with very high vulnerability include the coastal zone directly adjacent to the shoreline and residential areas. This study is expected to serve as a reference for local governments and disaster management agencies in efforts to mitigate and plan safer spatial arrangements against tsunami threats. Mitigation strategy recommendations include the construction of evacuation routes, safe shelters, and the regular enhancement of disaster education and simulations for the community. Furthermore, this research encourages the use of mountainous areas as primary evacuation zones and collaboration with research institutions for the development of more innovative mitigation technologies.
