Abstract

This study aims to identify and analyze the impact of the Galodo disaster in Sungai Jambu (Pariangan, Tanah Datar, West Sumatra) using PlanetScope satellite imagery. Galodo disasters, which are flash floods that transport materials such as soil and rocks, often occur in mountainous areas and cause significant damage to the environment and infrastructure. Located on the slopes of Mount Marapi, Sungai Jambu is one of the areas prone to galodo due to its geomorphology and high rainfall. The research methodology involved using PlanetScope images before and after the Galodo accident on May 13, 2024. Data processing included radiometric and geometric correction as well as image composite analysis to detect changes in land cover and river flow. The 3-2-1 and 4-3-2 composite images were used to detect changes in vegetation, stream conditions and degraded open land. The results showed significant changes in land cover and river flow due to the Galodo disaster, characterized by increased water turbidity and damaged vegetation. This study confirms the effectiveness of PlanetScope images in monitoring and identifying the impacts of the Galodo disaster. These findings provide important information for post-disaster mitigation and recovery planning and help identify areas that require restoration. Thus, the use of PlanetScope images can improve our understanding of environmental damage caused by disasters and support more effective and sustainable mitigation measures

Abstract

This study aims to design an efficient boat-pulling machine to support traditional fishermen at Pasie Katapiang Beach, Padang Pariaman. The research method employed is the design of the tool based on the principles of design engineering, involving a systematic process in creating a machine that can assist fishermen in the boat docking process more efficiently. Through calculations and planning, it was found that the force required to pull the fishermen's boat is 6,522.88 N, using a shaft made of ST 37 material with a diameter of 22.413 mm. The rotations generated on the transmission shaft are 2000 rpm, while on the wheel and drum shafts are 750 rpm and 500 rpm, respectively. The selection of a slip clutch with 2 bolts on the transmission shaft and the use of pillow block bearing ucp 206 ass 30 with specified bearing life estimates have been considered in the machine design. Practical test results indicate that the time required to reel or pull the boat is 0.98 minutes. In this research, the design of the boat-pulling machine meets operational needs. It has the potential to positively contribute to improving the work efficiency and welfare of traditional fishermen in the field

Abstract

Land Surface Temperature (LST) is widely utilized in current studies, particularly as an initial survey tool to assess geothermal activity in locations suspected to have geothermal sources. The research method involves geometric correction of Sentinel-3 imagery and conversion of temperature units from Fahrenheit (F) to Celsius (C) to ensure accuracy in temperature measurement. Image data processing from Sentinel-3, including thermal band analysis, is carried out to generate land surface temperature values. The field-measured temperatures are then compared to the land surface temperature data obtained through processing. The temperatures in the location, ranging from 23°C to 35°C, fall within the minimum geothermal temperature range, indicating potential geothermal activity. However, the LST values from the image data exhibit some differences compared to the on-site measurements. These discrepancies are categorized into classes I (23.7 – 24°C), II (24 – 24.3°C), and III (24.3 – 24.8°C), marked by red areas in the LST values. These discrepancies are attributed to various factors during image recording and processing, such as atmospheric interference and sensor calibration.

Abstract

This study aims to analyze the influence of Human Resource (HR) quality on crew performance at Bourbon Offshore Asia Pte., Ltd. The main focus of the research is how HR quality affects the operational effectiveness of ships, which directly impacts safety and work efficiency in the maritime environment. This study employs a quantitative method using a questionnaire instrument that has been tested for validity and reliability. The data is analyzed using linear regression to determine the relationship between HR quality and crew performance. The results indicate that the majority of crew members have 0–4 years of work experience, highlighting the need for more effective training strategies to enhance their competencies. In terms of job distribution, 53.75% of the crew consists of deckhands (ABK), who play a crucial role in daily ship operations. The regression test results show a positive and significant effect between HR quality and crew performance, with a correlation value of 0.926. The coefficient of determination (R² = 0.857) indicates that 85.7% of crew performance variation is explained by HR quality, while 14.3% is influenced by other factors. Key factors improving crew performance include individual competence, work productivity, and compliance with safety standards. However, aspects such as work initiative and task completion require further attention.

Abstract

The research aims to analyze maritime safety and security policies in supporting the maritime transportation system. This research uses a descriptive method, because the data collected are in the form of words, images, and not numbers. The data comes from interview scripts, field observations/notes, Focus Group Discussions, videotapes, photographs, notes or memos, and other official documents. Data analysis uses an ethical and emic approach and a triangulation process. Informant determination uses a purposive technique. Research result: Maritime transportation in Indonesia has not yet developed optimally, but has strong potential to be developed, considering its characteristics of being able to carry out mass transportation. Therefore, the safety and security system is a key factor that must be considered and as a basis and benchmark for decision making. The safety and security system for maritime transportation in Indonesia has not been running optimally, accidents still often occur both due to natural factors and human factors. Government policies in the maritime sector, both the fishing industry and the shipping industry have not been implemented consistently in accordance with applicable laws. So far, the development of maritime potential has been hampered by structural problems, and there has been no national political awareness of the magnitude of the economic, fisheries and maritime potential.

Abstract

Cargo change operations on tanker vessels carry a risk of contamination if the tank cleaning process is not performed optimally. The problem addressed in this study is the less-than-optimal implementation of cargo contamination prevention procedures during cargo change operations on board MT SAMUDERA BIRU 168. This study aims to analyze the level of implementation of tank cleaning procedures and identify factors and constraints that influence the effectiveness of its implementation. This research employed a descriptive qualitative method using a fishbone analysis approach. Data were obtained through direct observation, interviews with officers and crew members, and ship documentation. The analysis classified potential causes into several aspects, namely human resources, work methods, equipment, supervision systems, and working environment conditions. The results show that tank cleaning procedures were generally carried out according to the established stages, from stripping to final inspection before the tanks were declared dry and up to dry. However, the implementation was not fully optimal, as indicated by flushing duration not consistently reaching 30 minutes, uneven spraying in upper frame areas, and slight moisture detected during inspection. The influencing factors include human resources, operational time pressure, hot working conditions inside the tanks
