Abstract

Monitoring mangrove vegetation is an essential initial step in mangrove management. The aim of this study was to observe the spatial and temporal changes in the coverage and extent of mangrove vegetation in the Jawai District. The method used in this research was remote sensing through geometric analysis of changes in coverage and the density of mangrove vegetation using the Normalized Difference Vegetation Index (NDVI) and Green Chlorophyll Index (GCI) as indicators of mangrove vegetation health. The results of the analysis using Landsat 8 satellite imagery recorded in 2013 and 2023 as input data revealed that the extent of mangrove vegetation coverage experienced both increases and decreases in certain villages. A total of six villages saw an increase in mangrove vegetation covering 171.2 hectares, including Dungun Laut, Sentebang, Sei Nyirih, Parit Setia, Pelimpaan, and Sarang Burung Kuala. Meanwhile, five villages experienced a reduction in mangrove vegetation area, comprising Bakau, Sarang Burung Usrat, Sarang Burung Kolam, Sei Nilam, and Sarang Burung Danau. The village with the largest increase in mangrove area was Parit Setia, with an addition of 45.075 ha, while the greatest decrease occurred in Sarang Burung Usrat, with a reduction of 32.917 ha. Furthermore, the NDVI and GCI values showed a similar pattern, with an increase in index values from 2013 to 2023. When the NDVI value increases, the GCI value also increases. The density of mangrove vegetation based on NDVI ranged from 0.0249 to 0.4300 in 2013, and increased in 2023, ranging from 0.0451 to 0.5117. The GCI values in 2013 ranged from 0.0030 to 1.1628, and in 2023 they ranged from 1.0499 to 2.5708.

Abstract

Arenga pinnata Merr (APM) has excellent strength compared to other natural fibers. However, until now its application in the industrial sector is still very low. This study is an experimental study aimed at analyzing the mechanical properties of Arenga pinnata Merr “ijuk” reinforced polyester biocomposite and its potential as a basic material for fiber ship hulls with alkalization treatment on the fiber. This research method is based on mechanical testing of several specimens with fiber content of 0, 5, 10, 15, to 20%wt soaked in 2% NaOH solvent for 3 hours, temperature 70oC. Furthermore, tensile testing of single fiber and biocomposite, bending test, hardness test, and Impact test were carried out with 5 repetitions each. The results obtained include a single fiber tensile strength of 1.1 GPa. For the highest composite tensile strength at 15%wt fiber of 61.27 MPa. The highest Elongation value at 20%wt fiber (3.19%). The highest bending strength at 0%wt fiber is 93.21 MPa. The highest hardness value at 5%wt fiber is 83.7 HD and the impact toughness value on the composite with 20%wt fiber is 1.31 J/mm2. Based on the results of the biocomposite mechanical test, if the biocomposite material is used as the basic material for making fiber ship hulls, then based on BKI standards, the mechanical strength value of the polyester-APM biocomposite does not comply with BKI standards.

Abstract

The global shipping lane for international trade in logistics and maritime is a shipping lane that has a high traffic density. Shipping on congested shipping lanes has great potential for the risk of ship damage. To improve shipping safety on dense shipping lanes, the purpose of this study is to analyze the relationship between ship's internal factors and shipping safety performance on dense shipping lanes, analyze the relationship between environmental factors and shipping safety performance on dense shipping lanes and obtain a model of shipping safety performance on dense shipping lanes. The method chosen to achieve the objectives of this study is a quantitative method with the Structural Equation Model (SEM) analysis technique with Smart PLS. The data of this research was obtained from the answers to a questionnaire that will be distributed to the crew of Indonesian-flagged commercial ships that have travelled through dense shipping routes, with a total of 150 crew members. The novelty of the research is a model of shipping safety performance in dense shipping lanes from the perspective of internal and environmental factors. The model shows the relationship of internal ship factors to shipping safety performance on dense shipping lanes by 30.9% and environmental influences on shipping safety on dense shipping lanes by 14.5%.

Abstract

The reciprocal tariff policy implemented by the United States toward its trading partners, including Indonesia, has exerted significant pressure on the competitiveness of Indonesia’s exports. Key sectors such as textiles, agriculture, and light manufacturing have been among the most affected. In this context, logistics efficiency, particularly port management as a strategic node in the export supply chain play a pivotal role. This study aims to analyze the impact of such tariff policies on Indonesia’s export performance, identify structural challenges in port management, and formulate strategies for integrating port governance into national policy frameworks to enhance export competitiveness. Employing a qualitative approach, this research utilizes data collection techniques including document analysis and in-depth interviews with stakeholders in the port, logistics, and trade sectors. The findings indicate that tariff barriers undermine export competitiveness, and inefficiencies in the port system driven by poor inter-agency coordination, infrastructural disparities, and fragmented logistics policies emerge as critical constraints. The study underscores the importance of an adaptive, collaborative, and nationally coordinated port management strategy to bolster Indonesia’s response to the growing pressures of global protectionism. It highlights the urgent need for comprehensive reform in port governance to strengthen Indonesia’s position in the international export market.

Abstract

This study investigates the spatial variability of water quality in Jakarta Bay using remote sensing techniques, focusing on turbidity and sediment levels. The research employs Sentinel-2A satellite imagery processed through Google Earth Engine (GEE) and utilizes two key parameters: the Normalized Difference Turbidity Index (NDTI) and Total Suspended Solids (TSS). Jakarta Bay, a shallow marine area in northern Jakarta, is significantly affected by urban runoff, industrial waste, and other anthropogenic pressures. Five observation points were selected to represent different environmental conditions and levels of human influence. The analysis revealed distinct variations in water quality. Point 1 exhibited the highest turbidity (NDTI = 0.21) and TSS (46.81 mg/L), indicating a heavy presence of suspended particles likely due to upstream discharge and shoreline activity. Point 5 showed the lowest turbidity and TSS values, suggesting clearer water and minimal pollutant input. Interestingly, point 3 had the highest turbidity (NDTI = 0.23) but the lowest TSS (23.49 mg/L), reflecting the presence of fine particles that increase light scattering but contribute less to sediment mass. The use of satellite-based indicators proved effective in identifying spatial differences in water quality across Jakarta Bay. This approach offers a cost-efficient, large-scale monitoring method that supports environmental assessment and planning. The results underscore the impact of local factors on water conditions and demonstrate the importance of combining turbidity and sediment metrics. Ultimately, this study provides valuable insights to guide targeted water management strategies and contributes to achieving Sustainable Development Goal 6: ensuring clean water and sanitation for all.

Abstract

The analysis of barge structural strength is crucial for ensuring safe and efficient load-out processes, particularly in evaluating the structure's capacity to withstand top-side loads during transfer from jetty to transportation barge. This study employs Finite Element Analysis to assess the barge structural integrity during the load-out process using the skidding method. Results demonstrate that the maximum von misses stress reaches 74.119 N/mm2 with a unity check (UC) of 0.422 < 1, while the maximum normal stress is 57,734 N/mm2 (UC 0.411 < 1), and shear stress remains minimal at 2.123 N/mm2 (UC 0.024 < 1). Peak stress occurs in load case 2, with the skid frame's ground bearing pressure at 6.83 Ton/m2 across an 85.05 m2 barge surface area. The findings validate that the skidding method is a viable approach for analyzing barge structural strength during load-out operations.

Abstract

Indonesia's maritime territory covers an area of 6,400,000 km², accounting for more than 77% of its total area, presenting significant prospects for maritime trade and economic growth through sea trade. With ports serving as important gateways for trade in goods, maritime transportation commands an 80% share of the global market. However, the handling of dangerous goods poses significant risks, requiring strict adherence to the International Maritime Dangerous Goods Code (IMDG Code) to ensure safety and compliance. Current challenges include inadequate regulations, non-compliance with Standard Operating Procedures (SOPs), and cases of document manipulation, which exacerbate safety concerns. This study proposes the utilization of Radio Frequency Identification (RFID) technology as a solution to enhance the process of identification, verification, and real-time monitoring of dangerous goods, thereby improving operational efficiency and accuracy. A Research and Development (R&D) method focused on potential problems identified through stakeholder interviews revealed common issues such as misclassification of goods and lack of transparency in documentation. The new RFID system features components such as tags, readers, and a management system that integrates live tracking and automatic classification verification. After conducting a pilot test, the system showed a 95% accuracy rate in item identification, which significantly reduced misclassification. The recommendations include phased implementation at key ports, cross-agency collaboration, comprehensive training for personnel, and future upgrades to RFID technology with Internet of Things (IoT) integration to further improve transparency and data security in dangerous goods logistics in Indonesia.

Abstract

Coconut meal is an agricultural waste that has not been widely utilized but still contains nutrients. This study aims to evaluate the effect of fermentation on the protein, fat, and carbohydrate content of coconut meal. Three main treatments were compared: unfermented coconut meal, coconut meal fermented with Rhizopus sp., and coconut meal fermented with EM4. The results of the analysis showed that unfermented coconut meal had a protein content of 34,77%, fat 8,84%, and carbohydrate 27,73%. Fermentation with Rhizopus sp. increased the protein content to 37,37%, decreased the fat content to 6.11%, and slightly increased the carbohydrate content to 23,04%. Meanwhile, fermentation with EM4 increased the protein content to 35.87%, decreased the fat content to 6.55%, and increased the carbohydrate content to 26.86%. Based on the results of the study, fermentation with Rhizopus sp. was more effective in increasing protein content and decreasing fat content compared to fermentation with EM4. Fermentation with EM4 showed a significant increase in carbohydrate content. In conclusion, the fermentation process can improve the nutritional quality of coconut meal, so that it can be a more nutritious alternative as animal feed
