Abstract

Ships as the main mode of transportation that has a strategic role in trade transportation, the trade supply chain really needs proper operations. The operational of the ship is greatly influenced by the performance of the main engine. One of the critical components of the main engine is the exhaust valve which functions to regulate the release of exhaust gas from the combustion chamber to the exhaust manifold. The research is qualitative, collecting data through observation, documentation, and interviews. The event tree analysis (ETA) method is implemented the sequence of impacts produced by exhaust valve, such as high working temperatures, low engine performance, and standard functions described in the manual book so that leaks can be identified. So, From this analysis, the impacts that are traced sequentially to the performance of the exhaust valve itself can also be found. In addition, a fishbone diagram is used to describe the factors that cause leaks, including human error, managerial deficiencies, neglected inspections, and errors in maintenance techniques. Thus, the right handling can be found to overcome exhaust valve leaks, such as repairs required while the engine is stopped, repeated spare part submissions from ship management, conducting spindle thickness inspections, and improving maintenance techniques as specified in the engine manual book. Proper and effective preventive and handling actions based on the root causes outlined are essential to ensure proper operation of the machine.

Abstract

The ballast pump is one of the important components in the ship's balance system that functions to regulate the volume of ballast water in the ship's tank to maintain the stability and trim of the ship. The ball bearing component plays a role in reducing friction between the pump shaft and the pump housing and ensuring that the shaft remains aligned when the pump is operating. This study aims to determine the causes of ball bearing damage to ballast pumps, the impact caused by the damage, and preventive efforts that can be made. The method used in this research is descriptive qualitative with data analysis techniques using the fishbone method, namely with cause-and-effect diagrams. The results showed that the damage to the ball bearing of the ballast pump was caused by the lack of lubrication and the lack of checking and maintenance. The handling of this problem is done by disassembling the ballast pump and replacing the ball bearing and mechanical seal.

Abstract

Entrepreneurship has become a crucial pillar in economic development, particularly in addressing the challenges posed by globalization and the Fourth Industrial Revolution (Industry 4.0). This study aims to quantitatively describe the impact of entrepreneurship education on students' entrepreneurial interest. Sampling was conducted using a purposive sampling method, selected based on the researchers’ considerations. The reason for this sampling technique was that the selected classes had completed the entrepreneurship course. Total sampling was used, resulting in a sample of 121 students from four selected classes. The research instrument was an online questionnaire distributed to the students, and the collected data were analyzed using regression analysis to evaluate students’ perceptions of entrepreneurship education. The results of the study indicate that entrepreneurship education has a “positive” impact on students' entrepreneurial interest, as represented by indicators such as self-confidence, creative and innovative thinking, future orientation, as well as the enhancement of honesty and independence values among students.

Abstract

Ground-mounted solar panels are directly exposed to environmental conditions, particularly wind, making structural design essential. While wind tunnel experiments have been a primary research method, they are costly and time-consuming. Computational Fluid Dynamics (CFD) simulations provide an efficient alternative by accurately modeling fluid-structure interactions, allowing for detailed aerodynamic analysis without physical testing. This study examines a solar panel configuration of 2×18 (1700×1200 mm panels) under a wind speed of 30 m/s at a height of 10 m. Wind direction variations (0°, 30°, 60°, 90°, 120°, 150°, 180°) significantly impact aerodynamic behavior. Drag Force analysis reveals that frontal wind (0°) generates the highest drag, while lateral wind (90°) has the least effect. Surface Pressure and Surface Coefficient (Cp) analysis indicate maximum pressure at 0°, where Cp values are highest, highlighting a pronounced pressure differential. At 90°, pressure distribution is more uniform, reducing aerodynamic impact. At 180°, rear-side pressure remains influential but lower than frontal exposure.

Abstract

Lombok Island is home to a rich culinary heritage, with traditional dishes deeply rooted in Sasak culture and potential functional food value. This literature review investigates five iconic Lombok dishes—Ayam Taliwang, Plecing Kangkung, Sate Bulayak, Ares, and Beberuk Terong—focusing on their nutritional profiles, bioactive compounds, and health-related properties. Adopting the PRISMA-ScR approach, this study synthesizes 30 scientific articles published between 2014–2024 and compares findings with the Indonesian Food Composition Table (TKPI). Results reveal the presence of bioactive compounds such as capsaicin, curcumin, allicin, flavonoids, and nasunin, with antioxidant, antidiabetic, immunomodulatory, and cardioprotective effects. The review highlights challenges in food safety (e.g., acrylamide, aflatoxin risks), along with the need for standardized recipes and modern packaging strategies. The paper recommends further scientific validation and sustainable innovation to transform Lombok's traditional cuisine into evidence-based functional food products that strengthen local identity, promote public health, and boost Indonesia’s healthy food industry.

Abstract

This study aims to describe the socio-economic characteristics of cattle breeders in Andolo District, South Konawe Regency. The method used is quantitative descriptive with a purposive sampling approach to 40 breeders. The results show that most breeders are of productive age (25–55 years), male, have a high school education, and have more than 10 years of livestock farming experience. The maintenance system used is comprehensive and traditional. This livestock business is a side job with an average ownership of 3 cows of their own. The annual income from large livestock businesses ranges from 5–10 million rupiah, and livestock is generally used as family savings. These findings indicate that cattle farming in this area is still subsistence and has not developed commercially.
