Abstract

Wastewater treatment systems are vital to secure the public health and environment by processing wastewater to be less harm. This research aims to analyse the domestic wastewater management system and develop strategic management steps specifically for the Lhokseumawe City area. The method employed is a quantitative analysis using a cross-sectional approach. Primary data were collected through field surveys, questionnaires, and interviews, while secondary data included population and city maps. Data analysis utilized the Chi-Square test to determine correlations between respondent characteristics, such as age, education, and income, and their knowledge or attitudes regarding wastewater treatment plants (WWTP). Results and discussion reveal that Lhokseumawe residents generally hold positive knowledge (75%) and attitudes (86%) toward wastewater management. Significant correlations were found between education levels and management knowledge (α < 0.05). While Muara Satu residents showed the most positive engagement, otherwise the Blang Mangat community requires further educational intervention. The conclusion suggests that local governments should strengthen community-based training and awareness campaigns, particularly targeting youth, women, and low-education groups, to ensure sustainable and effective wastewater management.

Abstract

Gas leakage in pipeline systems represents a critical hazard in the oil and gas industry, posing significant risks to human safety and the environment. This study aims to perform a probabilistic analysis of natural gas dispersion resulting from pipeline leakage using ALOHA (Areal Locations of Hazardous Atmospheres) integrated with statistical wind data analysis. Meteorological data over 25 years (2000–2024; 219,167 observation hours) were analyzed using Weibull distribution and wind rose methods to characterize the dominant wind regime. The results indicate that low wind speeds (0.5–2.5 m/s) dominate site conditions (77.1%), limiting gas dilution and increasing accumulation near the source. The dominant dispersion direction is identified in the southwest-to-south sector (213.75°–236.25°). Under these conditions, the red zone (≥30,000 ppm, 60% LEL) extends approximately 89.6 m, while in worst-case scenarios it reaches up to 198 m. Vapor Cloud Explosion (VCE) overpressure remains below 1.0 psi. Probabilistic integration of all scenarios produces a consequence probability map identifying high-risk zones along the right-of-way (ROW). These findings support improved risk assessment and provide a basis for targeted mitigation strategies in pipeline safety management.

Abstract

The IMO has introduced the Carbon Intensity Indicator (CII) to reduce carbon emissions, and it will be mandatory for ships sailing internationally from 1 January 2023. Implementing CII should be a top priority for reducing greenhouse gas emissions from ships sailing in Indonesia’s territorial waters, the world’s largest maritime country. This study aims to determine the constant in the empirical formula for monitoring fuel consumption and CII implementation using Automatic Identification System (AIS) data from MV. Meratus Padang. The Holtrop method is used to calculate the ship’s basic resistance, and the STAWAVE method is then applied to account for environmental conditions during sailing to obtain more accurate results under actual conditions. The total resistance of the Holtrop and STAWAVE methods can be used to calculate the power supplied to the propeller. Furthermore, the propeller’s power can be used to calculate fuel consumption. The fuel consumption calculation showed differences of 0.41% on the Surabaya-Banjarmasin route and -0.35% on the Banjarmasin-Surabaya route, with a propeller efficiency of 0.5 and an engine degradation of 9.5%, as the average CII is “E”.

Abstract

Project delays remain a persistent challenge in the oil and gas industry, where conventional scheduling methods such as the Critical Path Method (CPM) fail to adequately address resource constraints and duration uncertainty. This study evaluates the effectiveness of Critical Chain Project Management (CCPM) as an alternative scheduling approach for Ultra-Low Pressure (ULP) compressor installation projects. A case study methodology was applied using actual project data from Pamaguan Plant, PT Pertamina Hulu Sanga Sanga, involving Work Breakdown Structure analysis, critical chain identification via Microsoft Project, and buffer sizing using the Root Square Error Method (RSEM). From 1,096 activities, 86 critical activities formed the critical chain, yielding a project buffer of 28 days and 27 feeding buffers. Buffer utilization reached 171%, placing the project in the red zone, indicating the planned buffer was insufficient to absorb delays caused by duration variability, resource limitations, and behavioral phenomena including Student Syndrome and Parkinson's Law. These findings confirm that CCPM offers a structurally superior scheduling framework compared to CPM, yet its effectiveness depends on disciplined execution and proactive buffer monitoring. This study contributes quantitative evidence on buffer utilization effectiveness in oil and gas project scheduling, providing practical guidance for managing high-complexity installation projects.

Abstract

Subsea pipelines are critical offshore infrastructures for transporting oil, gas, and produced fluids, but they are exposed to structural degradation, environmental loading, and third-party interference that may lead to leakage or failure. This study evaluates subsea pipeline damage risk by integrating Fault Tree Analysis (FTA), Event Tree Analysis (ETA), and Bowtie Analysis. Risk identification classified the main hazards into pipeline structural integrity failure and third-party interference. The FTA results show that the probability of subsea pipeline damage as the top event is 0.0297492, with pipeline structural integrity failure contributing 0.0179766 and third-party interference contributing 0.0119882. The dominant basic events are failure to conduct periodic inspection, corrosion, gasket failure, emergency anchoring, and severe weather conditions. ETA was applied to assess consequence pathways after pipeline damage through six safety barriers: detection and alarm, alarm verification and decision making, emergency shutdown and isolation, pressure and inventory control, area control and secondary impact prevention, and emergency response, inspection, and repair. The results indicate that minor damage with no significant fluid release has the highest probability, whereas catastrophic loss of containment has the lowest probability but the most severe impact. Bowtie Analysis integrates the causal and consequence pathways into preventive and mitigation controls for integrity.

Abstract

Technological developments have encouraged the shift in the main material from wood to Fiber Reinforced Plastic (FRP) because of its light weight, noncorrosive, lower price, and simple production process. However, traditional FRP boat production in Indonesia generally has not implemented the construction standards set by the Indonesian Classification Bureau (BKI), including those of CV. Roni Marine boat production. This study aims to describe the construction of FRP boats produced by CV. Roni Marine and assess its compliance with BKI standards. The research was conducted through direct observation at CV. Roni Marine, measuring the dimensions of the 9.5 m FRP boat construction, and literature studies of the BKI standard documents. The main components of boat construction analyzed include the boat's skin, keel, frames, longitudinal stiffeners, and deck beams. The results showed that the CV. Roni Marine uses a combination of transverse and longitudinal construction systems with laminated materials, including CSM300 and WR600 fibers. The thickness of the hull laminate is 2.13 mm. The spacing between frames is 580 mm, length of the longitudinal stiffeners is 8,700 mm, the width of the keel lamination is 60 mm, and the spacing between the deck beams is 2,900 mm. The results show that 100% of the boat construction does not comply with BKI standards

Abstract

Maintaining low storage temperatures on fishing vessels is strongly influenced by the insulation performance and durability of fish-hold lining materials, especially under humid and splash-exposed marine conditions. This study investigates latex–coconut coir composites as a lightweight, locally available, and bio-based candidate for insulation applications in small fishing vessels. Composite specimens were fabricated using a controlled formulation series from neat latex (100/0) to 50/50 latex–coir, with intermediate ratios of 90/10, 80/20, 70/30, and 60/40. The work emphasizes manufacturability, mass-related properties, and moisture behavior relevant to shipboard service. Water absorption was evaluated after 24 h immersion following the general procedure of JIS A 5908, while specific gravity and density were determined using an Archimedes-based method (ASTM D 792) at 23°C. The results show that increasing coir content reduces the dry specimen mass, supporting lightweight panel development, but significantly affects moisture uptake. Neat latex exhibits minimal water absorption (0.846%), whereas coir-containing composites show higher absorption with a non-linear trend, peaking at the 80/20 formulation (17.345%) and decreasing at 50/50 (10.410%). In contrast, specific gravity (~0.498–0.500) and density (~497–499 kg/m³) remain nearly constant across formulations, indicating that moisture performance is governed primarily by microstructure (porosity and latex–fiber interfacial sealing) rather than bulk density. These findings highlight the feasibility of latex–coir composites for marine insulation, while underscoring the need for processing optimization and/or surface sealing to improve moisture resistance.

Abstract

This study presents the design and implementation of an independent battery and lost-link fail-safe module to improve the navigational safety and operational reliability of Unmanned Surface Vehicles (USVs). Previous studies on USV fail-safe systems mainly focused on battery monitoring or communication recovery separately and generally relied on the main onboard controller or autopilot system. Such approaches may reduce system reliability when the primary controller experiences malfunction or communication interruption. To address this limitation, the proposed system integrates a Jetson Orin Nano, a CUAV autopilot, and an independent ESP32-based monitoring module capable of autonomously monitoring battery and communication conditions. Communication reliability is evaluated using MAVLink heartbeat signals, while battery condition is assessed using a progress-based energy estimation method to predict mission feasibility according to the remaining battery capacity and mission progress. When abnormal conditions such as low battery or communication loss are detected, the system autonomously activates fail-safe actions, including return-to-home and loiter modes, to prevent mission failure and vehicle loss. Experimental results show that the proposed system achieves a voltage measurement accuracy of 99.87%. In addition, the fail-safe mechanism successfully detects low battery conditions within 2.5–3.0 seconds and communication loss within 6–15 seconds, demonstrating improved USV operational safety and reliability.

Abstract

Communities that are still considered poor often identify with fishermen's households. This impression arises due to the simple condition of their houses and a lifestyle that often appears unbalanced between their income and expenses. This research focuses on exploring the level of welfare of the Pasar Sorkam community in Tapanuli Tengah from the aspect of their household financial management. The research employs a mixed methodology approach, supported by measurements of the community's welfare index. The research results indicate that the income level of the fishing community is classified as low, while the expenditure level is high. The fishing community in Pasar Sorkam Village has a welfare index value of 55.6, indicating that they fall into the low welfare category. The research is expected to serve as a reference for relevant future studies and as a guideline for policy formulation for the local government of Tapanuli Tengah Regency.

Abstract

Skipjack tuna (Katsuwonus pelamis) is a high economic value pelagic commodity in FMA 714, whose distribution is highly responsive to oceanographic parameters, particularly sea surface temperature and chlorophyll a. This study aims to analyze the influence of sea surface temperature and chlorophyll a distribution on the characteristics of potential skipjack tuna fishing areas in the waters of FMA 714 in 2022. The approach is a quantitative, descriptive method using simple linear regression to correlate NOAA datasets with fish catch statistics. Temporal analysis revealed that oceanographic dynamics are controlled by the monsoon cycle, particularly the upwelling process during the East Season. This period was marked by a drastic decline in sea surface temperature to 28°C in August, in contrast to a sharp surge in chlorophyll a concentration in July-August, reaching 0.48-0.50 mg/m³. Although these water conditions produced dynamic productivity, linear regression analyses showed that sea surface temperature was positively associated with fish catch, while chlorophyll a was negatively associated, though very weakly. Sea surface temperature and chlorophyll a did not have a significant effect on fish catch (p=0.239), indicating that these parameters explained only 23.9% of the variation in catch, with the remaining 76.1% influenced by factors outside the research model. Catch production is largely influenced by fishing gear. Purse seine with a single boat is the most widely used fishing gear, with as many as 2,328 fleets using it. This is another factor in the production of skipjack tuna catches in FMA 714.
