Abstract

Regional development is highly dependent on the effectiveness of transportation systems, particularly freight transport, which plays a strategic role in logistics distribution and economic growth. This study aims to describe the interest and behavior of freight vehicle drivers in the Mamminasata Metropolitan Area (Makassar, Gowa, Maros, Takalar), as well as to identify the factors influencing environmentally conscious driving behavior. A descriptive quantitative approach was employed through a survey of 200 drivers of trucks, containers, and heavy vehicles. The results show that drivers’ interest in driving safety is relatively high, while their economic interest falls into the moderate category, indicating a tendency to prioritize short-term income gains despite potential negative impacts on infrastructure and the environment. In terms of behavior, most drivers demonstrate moderate levels, with pre-trip and vehicle control behaviors rated as good, while shifting behavior, tactical behavior, and operational practices still require improvement. These findings highlight the importance of education and policy-based interventions to promote safe, efficient, and sustainable driving behavior, contributing to the development of environmentally friendly freight transport management in metropolitan areas.

Abstract

With the increasing demand for the fulfillment of the necessities of life, the shock market, which is located on the Sungguminasa - Bontonompo road section, is also developing slowly. The number of traders and buyers is increasing, the place to trade is wider and the transaction time is getting longer. Pasar Shock on the Sungguminasa - Bontonompo axis road is the only traditional market nearby and offers a relatively complete range of trading commodities within a 1 km radius of the settlement. With a relatively short distance and the attractiveness that the market is able to provide on the Sungguminasa - Bontonompo axis road. Apart from its very strategic location and high level of demand, the shock market on the Sungguminasa - Bontonompo axis road is also relatively easy to reach. This study aims to analyze the performance of the road on the capacity of traffic volume and the degree of saturation caused. The method used in this study is the Observation Method with data collection through direct observation in the field of the research object including data on the number of vehicles passing and one observation point is taken with different traffic flow directions. The results showed that the Sungguminasa-Bontonompo road network was still able to serve traffic transportation, the road capacity was = 2449 pcu/hour; volume of vehicle traffic = 3994 pcu/hour. The value of the degree of saturation DS = 1.63 so that it can be defined that the service level of the Sungguminasa-Bontonompo axis road belongs to category F or traffic jams, the speed is very low.

Abstract

Indonesia’s mining sector, particularly in areas like Morowali Regency, Central Sulawesi, faces significant geotechnical challenges due to its location in the Pacific Ring of Fire. One of the key concerns in open-pit mining operations is slope instability, which can lead to landslides, threaten worker safety, damage infrastructure, and disrupt production. This study evaluates the slope stability in the Sambalagi site of PT. Wosindo Berkat Abadi using the Morgenstern-Price method, a limit equilibrium approach known for its accuracy in heterogeneous slope conditions. Field data were collected, including slope geometry, geological conditions, material strength, and hydrogeological factors. The safety factor (FK) was calculated based on geotechnical parameters such as cohesion, internal friction angle, and unit weight of the slope materials primarily saprolite and limonite. The actual slope FK value at PIT D was found to be 0.974, below the standard requirement (≥1.3) set by the Ministerial Decree No. 1827K/30/MEM/2018. To improve stability, a revised slope design was proposed, including reducing slope angles to 35°, increasing bench widths to 2 meters, and decreasing slope height per bench to 4 meters. The simulation of this revised geometry showed that it could achieve the required FK value. The study contributes to safer and more efficient mine planning by demonstrating the importance of integrating detailed geotechnical analysis in slope design, especially in tropical high-rainfall mining regions.

Abstract

Coastal abrasion poses a significant threat to Indonesia, an archipelagic nation with one of the world’s longest coastlines. The phenomenon is particularly severe in Napabalano District, Muna Regency, where dense settlements, economic activities, and declining mangrove ecosystems increase exposure to erosion hazards. This study aims to assess the risk of coastal abrasion in Napabalano District using a GIS-based approach aligned with the Indonesian National Disaster Management Authority (BNPB) framework. Primary data, including GPS coordinates, satellite imagery, and field surveys, were integrated with secondary data such as demographic statistics, oceanographic parameters, and historical records of abrasion events. Spatial analysis in ArcGIS was employed to evaluate vulnerability, capacity, hazard, and disaster risk indices. Results show that all villages in Napabalano District fall into the high-risk category, with Napabalano and Napalakura recording the highest risk values due to concentrated populations, limited mangrove protection, and inadequate disaster management capacity. Social and economic vulnerabilities, including high poverty ratios and dependence on coastal livelihoods, exacerbate exposure, while institutional capacity remains critically low, marked by weak early warning systems and limited community preparedness. Mitigation strategies proposed include mangrove rehabilitation, strict coastal zoning enforcement, community-based disaster preparedness programs, and the establishment of effective early warning systems. These findings highlight the urgent need for integrated, multi-stakeholder approaches to strengthen resilience against coastal abrasion. The study provides a strategic basis for local government and community planning in managing and reducing the impacts of coastal hazards in Napabalano District.

Abstract

The rapid growth of road infrastructure in Indonesia has increased the demand of construction materials and at the same time, intensified environmental issues. The study explores the potential application of nickel waste- which is a byproduct readily available to Indonesia in the smelting of nickel- as a partial replacement to coarse aggregate in porous asphalt mixtures. The research not only assesses the technical performance but also the environmental impact of the nickel waste substitution which can be regarded as a contribution to the literature on sustainable management of the construction process and the circular economy. Key parameters such as stability, flow, void content and the Marshall Quotient were tested in the laboratory and were evaluated as per the Bina Marga and SNI requirements. The results refer to the fact that nickel waste may meet a number of technical requirements, reaching an ideal concentration of asphalt into 5.5 0-100 that, at the same time, can provide waste minimization and possible cost-saving benefits. However, due to the fact that nickel slag contains heavy metals, it requires the use of strong environmental risk management, such as leaching control and stabilization technologies. These findings indicate that the use of nickel waste is more than a technical innovation; it is a strategic direction of the ability to become resource-efficient, symbiotic in the industrial industry, and to govern the operation of infrastructure in a sustainable manner. Placing industrial waste in a new category as productive input, this research sheds some light on how policy can be changed, how to innovate in procurements, and how government, industry, and academia can collaborate. The study concludes that the addition of nickel waste to the porous asphalt mixtures could help improve the performance of roads, reduce environmental ecological impacts, and promote the green infrastructure agenda in Indonesia, assuming that there are regulatory protections and a systematic environmental check-up.

Abstract

The growth in the number of motor vehicles and high rainfall intensity increases the risk of water ponding on roads, thereby requiring pavement construction that is both safe and has good drainage capability. Porous asphalt is one solution; however, it tends to have lower structural stability due to its low filler content. Fly ash is a fine particle deposit resulting from coal combustion residue. This study examines the utilization of fly ash waste from the Nusantara Power Punagaya coal-fired power plant in Jeneponto as a filler substitute in porous asphalt mixtures based on REAM 2008. The aim is to evaluate the effect of fly ash variations (0%, 50%, 100%) on Marshall stability, abrasion resistance (Cantabro), and the microstructure of the mixture. Experimental methods were carried out in the laboratory, including testing the physical properties of aggregates and the chemical composition of fly ash, mix design, and SEM-EDS analysis. The results show that the use of fly ash meets the specifications for VIM, VMA, stability, flow, and Marshall Quotient (MQ), except for VFB, which did not meet the specifications for all variations. Cantabro weight loss values were 8.53% (0%), 10.27% (50%), and 9.77% (100%). SEM-EDS analysis revealed that fly ash particles bond well with asphalt, with dominant elements C (45.38%) and Si (33.84%), along with the formation of a new carbon (C). These findings indicate the potential of fly ash as an environmentally friendly filler to improve porous asphalt performance. Pertumbuhan jumlah kendaraan bermotor dan intensitas curah hujan yang tinggi meningkatkan risiko genangan air di jalan, sehingga diperlukan konstruksi perkerasan yang aman dan memiliki kemampuan drainase baik. Aspal berongga (porous asphalt) menjadi salah satu solusi, namun cenderung kurang stabil secara struktural akibat rendahnya kadar filler. Fly ash adalah partikel halus yang merupakan endapan dari tumpukan bubuk. Penelitian ini mengkaji pemanfaatan limbah fly ash dari PLTU Nusantara Power Punagaya, Jeneponto, sebagai pengganti filler dalam campuran aspal berongga sesuai spesifikasi REAM 2008. Penelitian ini untuk mengevaluasi pengaruh variasi fly ash (0%, 50%, 100%) terhadap stabilitas Marshall, ketahanan aus (Cantabro), serta mikrostruktur campuran. Metode eksperimen dilakukan di laboratorium dengan pengujian sifat fisik agregat dan kimia fly ash, desain campuran, serta uji SEM-EDS. Hasil menunjukkan bahwa penggunaan fly ash mampu memenuhi spesifikasi pada parameter VIM, VMA, stabilitas, flow, dan Marshall Quotient (MQ), kecuali VFB yang tidak terpenuhi pada semua variasi. Nilai kehilangan berat Cantabro masing-masing sebesar 8,53% (0%), 10,27% (50%), dan 9,77% (100%). Analisis SEM-EDS mengungkap bahwa partikel fly ash berikatan baik dengan aspal, serta terdapat unsur dominan C (45,38%) dan Si (33,84%), dengan pembentukan senyawa baru karbon (C). Temuan ini menunjukkan potensi fly ash sebagai filler ramah lingkungan untuk meningkatkan kinerja aspal berongga.

Abstract

This study analyzes the determination of Temporary Evacuation Shelters (TES) based on tsunami hazard mapping in Ujung Bulu District, Bulukumba Regency. The tsunami hazard assessment was carried out using the Cornell Multi-grid Coupled Tsunami (COMCOT) model with a scenario from the Flores Back Arc Thrust (Nusa Tenggara Barat segment, M7.5). Simulation results indicate that tsunami arrival times range between 49 and 56 minutes with wave heights of 0,2 - 1.96 meters, and a maximum inundation distance of 998 meters inland. Based on spatial analysis, field survey, and GIS processing, 6 TES locations are recommended across several sub-districts in Ujung Bulu, such as Bintarore, Tanah Kongkong, Caile, and Kalumeme. The TES locations are positioned 360–1130 meters from the coastline, with walking times between 5.3 and 15.2 minutes. These findings highlight the importance of spatial-based disaster preparedness strategies to minimize casualties and improve community resilience.

Abstract

Nickel mining activities at PT. Cipta Djaya Surya in Molore Village, North Konawe Regency, face a serious problem in the form of stagnant runoff in the mine front area due to the lack of an adequate drainage system and sedimentation pond. This condition not only disrupts smooth mining operations but also has environmental impacts, such as reddish discoloration of coastal waters and potential siltation. This study aims to analyze surface runoff discharge, design open channel dimensions, and design settling ponds appropriate to the hydrological and topographical conditions of the study site. The methods used include collecting rainfall data for the past 10 years from the Meteorology, Climatology, and Geophysics Agency (BMKG), hydrological analysis using the rational method, hydraulic calculations using the Manning equation, and planning channel and settling pond dimensions based on runoff discharge. The results indicate that the maximum runoff discharge in the study area can be managed by designing a trapezoidal open channel with dimensions appropriate to the flow capacity, while the designed settling pond can accommodate the runoff volume without overflowing. The implementation of a planned drainage system is expected to maintain smooth mining operations, minimize the risk of landslides, and mitigate the impact of coastal environmental pollution. Therefore, this research supports the implementation of Good Mining Practice (GMP) principles and can be used as a reference in sustainable mine drainage planning.
