Abstract

Maritime safety and environmental surveillance in Indonesia depend on the reliability of official data supporting artificial intelligence (AI). This study establishes an official-statistics baseline using BPS-Statistics Indonesia’s Marine and Coastal Resources Statistics 2023. It examines fishing-vessel fleets for 2021–2022 (34 provinces; 1,004,060 and 893,258 vessels), 118 classified fishing ports, 41 recorded oil-spill incidents (1999–2023), port-water monitoring at 27 sites and fisheries patrol records. Methods include concentration indices, k-means clustering with silhouette selection, principal component analysis, modified z-scores and Isolation Forest screening. In 2022, 88.8% of the recorded fleet was motorised; provincial distribution showed a Gini coefficient of 0.41. Three fleet typologies were identified: outboard-dominated, inboard-dominated and non-motorised-heavy. Ten of 94 provincial vessel-type changes were flagged as statistical outliers, while 10 of 27 water-monitoring sites reported none of three core parameters. In 2021, there was approximately one recorded inspection per 385 fishing vessels. These descriptive findings inform candidate AIS trajectory analytics, SAR oil-spill detection, optical satellite monitoring and smart-port planning. The study proposes a phased, data-first roadmap; it does not estimate the performance of operational AI systems in Indonesian waters.
TECHNO-ECONOMIC EVALUATION AND LIFECYCLE DECARBONIZATION PATHWAYS OF GREEN LOGISTIC SHIPS IN INDONESIAN ARCHIPELAGIC MARITIME FREIGHT NETWORKS: A SCENARIO-BASED ASSESSMENT Ni'matul Fahdiyah; Muhammad Ikhsan Setiawan; Ramadhansyah Putra Jaya

Abstract

Decarbonizing maritime freight in Indonesia requires the joint assessment of ship propulsion, energy storage, wind assistance, and port electrification. This study develops a transparent scenario-based appraisal of a proposed 3,000-DWT-class hybrid green logistic ship for an illustrative Surabaya–Banjarmasin feeder service. The concept combines an LNG/diesel powertrain, 1,200-kWh battery energy storage, a Flettner rotor, and a 1-MW onshore power interface. The analytical framework follows IMO guidance for the Energy Efficiency Operational Indicator (EEOI), separate well-to-wake accounting, and discounted cash-flow analysis; national port statistics provide contextual evidence but cannot establish vessel-level fuel use or cash flows. A numerical consistency check of assumptions reported in the submitted manuscript—USD 1.85 million additional investment and USD 412,000 constant annual net savings over 15 years at 7.5%—produces a scenario NPV of USD 1.787 million, an internal rate of return of 21.0%, and discounted payback of approximately 5.69 years. These are conditional calculations, not observed commercial outcomes. The proposed 38.6% fuel saving and 82.3% life-cycle abatement cannot be validated without measured duty cycles, verified component performance, and fuel/electricity emission factors. The principal contribution is therefore an auditable assessment protocol and an explicit data-validation agenda for Indonesian short-sea freight electrification.

Abstract

Indonesia’s archipelagic geography places considerable demands on marine transport, port environmental management and fisheries surveillance. This article develops an evidence-informed artificial intelligence (AI) framework linking public marine statistics to three proposed analytical functions: gradient-boosted water-quality prediction, recurrent time-series forecasting and vessel-trajectory anomaly screening. The study reviews the officially published BPS Marine and Coastal Resources Statistics 2023, related KKP fleet data and traceable peer-reviewed methods. Government-reported 2022 marine fishing craft totaled 893,258, while the 2022 fisheries production figures in a later BPS statistical compilation were approximately 7.49 million tonnes from capture fisheries and 14.78 million tonnes from aquaculture. The proposed four-layer architecture specifies data, preprocessing, analytics and human-validated decisions. Importantly, the submitted manuscript does not supply model code, station-level training data, out-of-sample predictions or patrol simulation logs; its claimed AI accuracy and fuel savings therefore cannot be independently validated. The contribution is a reproducible research design and evidence map rather than a demonstrated performance improvement.
