Abstract

Pengisian botol angin pada kapal merupakan proses vital untuk mendukung sistem air starting mesin utama dan bantu. Namun, pada kapal MV. HL Dalrymple Bay ditemukan indikasi penurunan kinerja kompresor, khususnya saat manuver, ditandai dengan lamanya waktu pengisian dan tekanan udara yang tidak mencapai standar. Permasalahan ini berisiko mengganggu operasional kapal secara keseluruhan. Penelitian ini difokuskan pada faktor yang menyebabkan turunnya kinerja kompresor pada proses pengisian botol angin, dan apa dampak dari penurunan kinerja tersebut terhadap efisiensi dan keselamatan operasional kapal. Penelitian ini menggunakan pendekatan kualitatif deskriptif. Pengumpulan data dilakukan melalui observasi langsung selama praktik laut selama 12 bulan, serta dokumentasi teknis lapangan. Data dianalisis untuk mengidentifikasi gejala, akar permasalahan, serta solusi teknis yang relevan. Ditemukan bahwa penyebab utama turunnya performa kompresor adalah sistem pelumasan yang tidak optimal, kebocoran pada cylinder head, serta keausan pada piston dan ring piston. Dampaknya adalah waktu pengisian botol angin menjadi lebih lama dari standar, serta munculnya potensi gangguan pada manuver kapal. Rekomendasi meliputi pelaksanaan perawatan berkala, penggantian komponen aus, serta peningkatan keterampilan kru melalui pelatihan teknis.   Filling the air bottle on the ship is a vital process to support the main and auxiliary engine air starting system. However, on the MV. HL Dalrymple Bay was found to indicate a decrease in compressor performance, particularly during maneuvering, characterized by long charging times and air pressure that did not reach the standard. This problem risks disrupting the overall operation of the ship. This study focuses on the factors that cause the decline in compressor performance in the process of filling air bottles, and what is the impact of this decrease in performance on the efficiency and operational safety of the ship. This study uses a descriptive qualitative approach. Data collection was carried out through direct observation during marine practice for 12 months, as well as technical field documentation. The data is analyzed to identify symptoms, root causes, and relevant technical solutions. It was found that the main causes of the decline in compressor performance were suboptimal lubrication systems, leaks in the cylinder head, and wear on the pistons and piston rings. The impact is that the time to fill the air bottle becomes longer than standard, as well as the appearance of potential interference with the ship's maneuvers. Recommendations include the implementation of periodic maintenance, replacement of worn components, and improvement of crew skills through technical training

Abstract

This study discusses the importance of Navigational Aids (SBNP) to ensure that vessels stay on a safe path when entering ports. A quantitative descriptive method with an Importance- Performance Analysis approach was used to measure the importance and performance of sensor tools based on ease, effectiveness, and credibility. The results show that the average importance value ranges from 4.0 to 5.0, while the performance value ranges from 3.3 to 4.7. Although the performance is quite good, several factors are still not optimal. The analysis shows that 6 out of 15 statements fall into the priority quadrant, indicating that some important factors meet user expectations, but improvements are needed in other areas. This study provides insights into the effectiveness and efficiency of SBNP in port navigation, with recommendations for performance improvements.

Abstract

This study aims to identify global digital readiness patterns using an innovative big data approach by integrating Principal Component Analysis (PCA) and the FASTCLUS clustering algorithm. By analyzing 1,076 observations from 2000 to 2023, this study focuses on four key indicators: secure server deployment and ICT infrastructure index. Referring to the Digital Readiness Framework, this study positions digital infrastructure and cybersecurity as the foundation of national digital capacity. PCA results show that two main components explain 56.35% of the total variance, and the clustering process produces strong segmentation with Pseudo F = 1275.85 and R² = 70.4%. Three digital readiness clusters were successfully identified: advanced (4 countries), moderate (64 countries), and transitional (1008 countries), each exhibiting distinct infrastructure and digital index characteristics. This study contributes a replicable, globally scalable classification framework for comparing digital readiness across countries. Its originality lies in the integration of big data techniques and unsupervised learning into national digital readiness assessments. These findings are important for supporting data-driven digital policy formulation, particularly for developing countries in designing more precise and contextual ICT resource allocation strategies.

Abstract

Less than Container Load (LCL) is defined as cargo whose volume does not fill a full container and its movement requires allocation of LCL handling charges. This study aims to conduct a comparative study of LCL handling charges between Line 1 Container Freight Station (CFS) facilities and Line 2 depot facilities. Differences in operational locations and customs status between Line 1 CFS and Line 2 depots are predicted to cause variations in cost structures that directly affect the efficiency of the logistics supply chain. This study has three main objectives: identifying LCL service procedures, analyzing the development of LCL throughput volume for the period 2021–2024, and comparing LCL handling charges between the two locations. The methodology used is quantitative with a descriptive approach. Data were obtained through observation, interviews, and document studies at the Commercial and Business Development Department. Data analysis involved calculating the Compound Annual Growth Rate (CAGR) to measure volume trends and descriptive comparative analysis to evaluate cost structures. The results show that LCL services are implemented through three main Job Orders: Receiving Service LCL (RSL), MIM, and Delivery Cargo. The LCL throughput trend shows a positive increase with a CAGR of 17.996%. Furthermore, the cost analysis results show that the Line 2 depot charges a higher LCL handling charge, which is around 26%–30% compared to the Line 1 CFS. Thus, the Line 1 CFS is proven to provide a competitive advantage for service users through a more efficient LCL charge handling structure.
