Abstract

The development of reliable road infrastructure serves as a key pillar in supporting regional connectivity, logistics distribution, and economic growth. In Indonesia, connectivity improvement policies have become a priority in the National Medium-Term Development Plan (RPJMN) 2020–2024 as an effort to accelerate equitable development, particularly in underdeveloped and archipelagic areas. This study aims to evaluate the pavement condition and determine the level of damage severity on the Amahusu–Latuhalat road segment in Ambon City using the Pavement Condition Index (PCI) method based on ASTM D6433. In addition, this study seeks to identify the distribution of pavement condition categories and propose appropriate maintenance strategies based on the obtained PCI values. The results indicate that the average PCI value of the 20 observed segments is 77.1, which falls into the “Good” category. The distribution shows that 35% of segments are in “Very Good” condition, 40% in “Good,” 10% in “Fair,” and 15% in “Poor.” These findings indicate that the pavement is still functionally adequate, although localized deterioration has occurred in several segments. Therefore, periodic maintenance and targeted rehabilitation are required to maintain pavement performance.

Abstract

Sea transportation plays a vital role in supporting inter-island connectivity in Indonesia, particularly in archipelagic regions such as Maluku Province. As a region consisting of numerous islands, Maluku relies heavily on sea transportation to facilitate economic, social, and cultural activities. Therefore, the quality of sea transportation services is an important factor in ensuring passenger satisfaction and service sustainability. This study aims to evaluate the quality of sea transportation services on KM Cantika Lestari 10C operating on the Ambon–Weda route based on passenger perceptions, and to identify priority aspects for service improvement using the Importance Performance Analysis (IPA) method. The study employed a quantitative approach using questionnaire data collected from passengers. The IPA method was used to analyze the level of importance and performance of service attributes, which were then mapped into four quadrants to determine priority improvements. The results show that the average performance score of service quality is 86.06, indicating that the overall service is categorized as “very good.” Most service attributes meet passenger expectations; however, several aspects related to safety and security fall into priority improvement categories. These include routine inspection of the ship’s technical condition and ensuring that safety equipment such as lifebuoys, lifeboats, and fire extinguishers are in proper condition and easily accessible. In conclusion, the service quality of KM Cantika Lestari 10C is generally very good, but improvements in safety and security aspects are necessary to enhance passenger satisfaction and ensure sustainable service quality.

Abstract

A solid conveyor is one of the important pieces of equipment used in palm oil processing industries to transport solid materials continuously. This study aims to describe the fabrication process of a solid conveyor at PT SOCFINDO Tanah Gambus and to analyze the application of Shielded Metal Arc Welding (SMAW) in the manufacturing process. The study was conducted through direct observation during an industrial internship program at the workshop division of PT SOCFINDO Tanah Gambus. The fabrication process included material preparation, cutting, flight screw forming, shaft fabrication, welding, assembly, inspection, and finishing. The results showed that the use of SMAW welding with E7016 electrodes produced strong and stable welded joints suitable for industrial conveyor applications. The conveyor design used a Schedule 80 steel pipe shaft, 8 mm steel plate flight screw, and UNP 100 support frame. The manufacturing process required accuracy in dimensional measurements, welding alignment, and assembly to ensure optimal conveyor performance. The implementation of proper fabrication procedures and welding techniques significantly affected the quality and durability of the solid conveyor used in palm oil processing operations.
