Abstract

Noise generally depends on the level of noise intensity and the length of exposure time. The influence of high intensity noise (above NAB) in engine room activities causes damage to the ears which can reduce hearing quality, both temporarily and permanently. Based on the problems above, it is deemed necessary to conduct research in the form of designing a monitoring system that is capable of detecting noise. In this research, the sensor used is the GY Max 4466 sound sensor to detect noise at 4 object points. The microcontroller used is an ESP WROOM-32 because it has 16 ADC pins which makes it possible to run more than one analog sensor. Before use, the sensor will be tested with the aim of finding out the sensitivity of the sensor that will be used as a monitoring system tool. This noise monitoring system is carried out in real time based on the Internet of Things so that it will be easier to monitor directly to support work health and safety data. Through graphic analysis and comparison tables of accuracy values ​​above, information is obtained that the GY Max 4466 sensor has a very high level of accuracy to be able to provide information on noise levels in the ship power plan laboratory at the Jakarta College of Maritime Science. This is given by the percentage value of the accuracy of the measuring instrument made. exceeds 90% or has a coefficient of determination R2 value close to 1.

Abstract

The modern transportation sector must consider its environmental impact particularly air pollution in addition to improving efficiency and speed. One of the main factors contributing to air pollution and global warming is the exhaust emissions produced by fossil fuel-based modes of transportation. Wing in Ground (WIG) craft are vehicles that use ground effect to fly low over water or land with lower energy consumption than conventional aircraft. This is one alternative mode of transportation that is beginning to attract attention. The literature explicitly addressing the relationship between WIG Craft design and air pollution impacts remains relatively limited; therefore, studies need to be developed that explore preventive measures to minimize air and noise pollution from this technology. Research focusing on the potential pollution and environmental impacts generated by WIG Craft is still very limited; this is because WIG Craft is a technology not yet produced for public transportation, and another factor is that research focus remains on design, stability, and control. Given these conditions, this study is important for identifying and formulating preventive strategies to reduce air and noise pollution from the use of WIG Craft. Purpose – This systematic literature review aims to comprehensively synthesize the current evidence on pollution prevention strategies in WIG craft design. Methodology – The initial phase of the study involved a systematic literature review. This Systematic Literature Review investigation was guided by the PRISMA analysis. Because of its substantial data collecting and comparatively strict and precise process. Findings – The potential emissions from WIG craft can be reduced through the design of green propulsion systems using electric power and low-carbon fuels. To mitigate the environmental footprint of Wing-in-Ground craft, researchers have proposed a combination of advanced aerodynamic design, noise suppression technologies, and optimized operational strategies.

Abstract

Coastal port cities face unprecedented challenges from climate change, urbanization pressures, and maritime traffic intensification, threatening both urban sustainability and maritime operational efficiency. This research develops a comprehensive Smart Port-City Integration Framework employing GIS-based spatial analysis and predictive modeling to address sea-level rise adaptation, traffic congestion mitigation, and land-use optimization. Through qualitative analysis incorporating perspectives from urban planning experts, maritime infrastructure specialists, and port authority administrators, this study identifies critical integration strategies balancing environmental resilience with economic vitality. The framework synthesizes civil engineering principles with sustainable urban planning methodologies, demonstrating how coastal cities can transform port-urban interfaces into climate-adaptive, economically productive, and socially equitable spaces. Findings reveal significant gaps in current planning approaches, particularly regarding climate risk assessment integration and stakeholder coordination mechanisms. The research contributes practical implementation pathways for port cities globally, offering evidence-based strategies for sustainable coastal development aligned with SDG 11 (Sustainable Cities) and SDG 13 (Climate Action), while enhancing maritime competitiveness through intelligent infrastructure design and resilient spatial planning frameworks.

Abstract

Efisiensi konsumsi bahan bakar pada kapal latih merupakan aspek krusial dalam menjaga keberlanjutan operasional dan kesiapan armada pendidikan pelayaran nasional. Penelitian ini bertujuan untuk menganalisis tingkat efisiensi konsumsi bahan bakar Kapal Latih (KL.) Mohammad Husni Thamrin milik Sekolah Tinggi Ilmu Pelayaran (STIP) Jakarta pada rute Pulau Baai – Pulau Enggano – Linau, membandingkan performa efisiensi antar rute, serta mengidentifikasi faktor-faktor yang memengaruhinya. Metode penelitian menggunakan pendekatan kuantitatif deskriptif dengan analisis data operasional sekunder berupa voyage log sebanyak 15 voyage pada periode November 2025, yang mencakup variabel jarak tempuh, durasi, konsumsi fuel oil, Remaining on Board (R.O.B), dan kecepatan kapal. Pengolahan data dilakukan menggunakan bahasa pemrograman Python dengan pustaka pandas, numpy, matplotlib, dan openpyxl pada platform Anaconda Jupyter Lab. Hasil penelitian menunjukkan rata-rata efisiensi bahan bakar sebesar 51,76 NM/Litre dengan koefisien variasi 22,85%, mengindikasikan variabilitas operasional yang tinggi. Rute Pulau Baai → Pulau Enggano teridentifikasi sebagai rute paling efisien (63,33 NM/L), sedangkan rute Linau → Pulau Enggano menjadi paling kurang efisien (44,08 NM/L). Voyage paling efisien dicapai pada voyage ke-5 (69,36 NM/L) dan paling boros pada voyage ke-1 (31,93 NM/L). Analisis regresi linier menunjukkan korelasi positif lemah antara kecepatan kapal dengan efisiensi bahan bakar (r = 0,2875; R² = 0,0827), sehingga faktor non-kecepatan seperti arus, cuaca, dan kondisi lambung diduga lebih dominan. Hasil penelitian ini diharapkan dapat menjadi dasar bagi penyusunan strategi optimasi operasional kapal latih, khususnya melalui penerapan weather routing, optimasi pre-voyage check, dan pengembangan sistem pencatatan data operasional yang lebih komprehensif.

Abstract

Container shipping logistics is a key determinant of the competitiveness of agricultural commodity exports; however, the mechanism by which service quality at the shipping agent level and container availability jointly determine export market share remains under-examined theoretically, and no empirical research exists on this topic—particularly in the export corridors of developing countries, where no previous studies have modeled these two driving factors simultaneously using causal inference methodology. This study examines the simultaneous effects of service quality (the five dimensions of SERVQUAL) and container availability on the export market share of PT Samudera Agro Logistics (SAL), a shipping agency operating fresh coconut and natural rubber export corridors in South Sumatra, Indonesia. A quantitative cross-sectional design was employed using Partial Least Squares Structural Equation Modeling (PLS-SEM), with data collected from 50 operational and managerial decision-makers at 10 active exporting companies, selected through purposive sampling based on direct involvement in SAL’s export service cycle and a minimum of one year of container logistics experience. The results indicate that container availability is the primary driver of export market share (β = 0.557; t = 5.054; p < 0.001), exerting a stronger influence than service quality (β = 0.432; t = 3.502; p < 0.01)—a finding that challenges the dominant view in maritime logistics literature, which focuses on service quality. Together, these two variables explain 57.9% of the variance in export market share (R² = 0.579), with large effect sizes (f² = 0.430 and 0.717) and adequate predictive relevance (Q² = 0.384), confirming the model’s robustness. As its primary theoretical contribution, this study introduces the Logistics Agent Competitiveness Model (LACM), an original framework that integrates SERVQUAL, Resource Based View (RBV), and Service Dominant Logic (SDL), which establishes that container availability is an independent strategic resource, not merely a sub-dimension of service quality, in determining the competitiveness of shipping agents. Practical implications are directed toward shipping agency managers prioritizing container fleet reliability, major shipping companies optimizing feeder allocation strategies, and policymakers addressing structural container imbalances in secondary export corridors.
