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

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.

One of the road pavement technologies currently being developed is porous asphalt. One of the materials used in flexible pavement mixtures is filler, one of which is ash. stone, which is in limited supply and relatively expensive. One alternative solution is to use empty oil palm fruit bunches. waste as an alternative material in the asphalt mixture. The aim of this research is what is the microstructure of asphalt mixtures that use empty oil palm fruit bunches as filler. This research uses the specifications of the Road Engineering Association of Malaysia (REAM, 2008). From the results of the research carried out, it can be concluded that the use of stone ash filler from empty palm fruit fruit bunches in hollow asphalt mixtures with variations of 2.5%, 5% and 7.5% shows that the granules are dense with voids that cover each other with varying sizes. This is in line with the stability value obtained from the Marshall test. Which has increased due to interlocking of interlocking grains. Meanwhile, from the EDS test results on the composition of chemical elements, it is known that the element contained in the hollow asphalt sample mixed with ash from burning empty oil palm fruit bunches with the highest compound composition is the element Boron at 66.55%, which is different from the chemical composition test for burning ash from bunch waste. The highest compound composition based on atomic percentage is Potassium (K) at 31.6%.

Abstract

Concrete is the main material in infrastructure development throughout the world. Its high mechanical strength and durability make it the main choice in various construction applications, from roads to high-rise buildings. However, behind its benefits, concrete production also triggers serious environmental problems. Natural aggregates such as river sand are used on a large scale. One of the materials that can be used as a substitute for fine aggregate is iron ore sediment waste. This study aimed to analyze the characteristics of fresh concrete using iron ore sediment waste as a substitute for fine aggregate using experimental methods. This study aimed to analyze the characteristics of fresh concrete using iron ore sediment waste as a substitute for fine aggregate using experimental methods. From the results of testing iron ore sediment waste aggregates such as the characteristics of iron ore sediment waste aggregates, 71% met the requirements as a material for making concrete, except for the mud content and organic content so special treatment is needed, namely the iron ore sediment waste material must be washed clean before use. The characteristics of iron ore sediment waste concrete have requirements from the average slump test value of 9 cm and there is no segregation and bleeding in the fresh concrete mixture.

Abstract

Indonesia faces significant challenges regarding energy consumption in the building sector, which continues to rise alongside urbanization and economic growth. Energy use in commercial buildings, particularly office and educational facilities, significantly contributes to the national total energy consumption, with HVAC (Heating, Ventilation, and Air Conditioning) systems being a major component of building energy consumption. By modeling HVAC systems, natural lighting, and thermal insulation, Building Information Modeling (BIM) can help optimize energy usage and reduce operational costs in buildings. However, despite the proven benefits of BIM in energy analysis and thermal comfort, challenges remain in its implementation. Many construction projects still rely on traditional methods that are less effective in integrating data and analysis. Additionally, a lack of understanding about BIM usage among construction professionals also hinders the achievement of optimal energy efficiency.

Abstract

Concrete, as one of the main elements in construction, has received special attention and is commonly used in infrastructure development in various countries in the world. High-quality concrete is increasingly needed along with the increasing need for infrastructure, such as towers, high-rise buildings, and long-span bridges. This type of concrete is made with a low amount of FAS; FAS or water-to-cementitious ratio is the ratio of the total weight of water to the total weight of cement in the concrete mixture. The purpose of this study is to analyze the water absorption of concrete using palm shells as a substitute for fine aggregate using an experimental method by curing. From the results of testing palm shells such as the water absorption value which is directly proportional to the increasing percentage of CKS use as a substitute for fine aggregate, it show that the use of CKS as a substitute for fine aggregate in normal concrete increases the water absorption of concrete, the higher the percentage of palm shell substitution, the higher the percentage of absorption value obtained.

Abstract

This study aims to evaluate reclamation activities on the post-mining land of PT Bumi Sentosa Jaya in Boedingi Village, Lasolo District, North Konawe Regency, Southeast Sulawesi Province. Mining activities carried out in the area have caused environmental degradation, particularly in soil quality and vegetation. Therefore, reclamation activities, including revegetation, need to be carried out to restore the ecological function of the land. This study uses the Normalized Difference Vegetation Index (NDVI) analysis method to evaluate the success rate of revegetation as an indicator of vegetation health and density. In addition, an analysis was conducted on the reclamation plan and the estimated costs required. The data used in this study consisted of Sentinel-2 satellite images and drone photos to obtain an accurate picture of topographical changes and vegetation growth. The results showed that the reclamation activities carried out by PT Bumi Sentosa Jaya succeeded in increasing vegetation density in the reclaimed area. The area of land that has been reclaimed reached 11.90 ha in the period from 2023 to 2024, with the success of revegetation measurable through an increase in NDVI values. The reclamation plan, which includes land preparation, planting of cover crops and pioneer plants, and plant maintenance, has been implemented in accordance with established standards. This study is expected to contribute to the development of reclamation and revegetation techniques in mining areas, as well as provide recommendations for companies and policy makers to improve the success of future reclamation activities.

Abstract

growing rapidly and have the potential to put pressure on the hydrological system of the Watershed (DAS) and the dynamics of sedimentation in coastal areas. The applied open-pit mining system causes extensive land clearing and reduced vegetation cover, which can increase surface runoff and soil erosion. This study aims to analyze the spatial relationship between nickel mining land clearing, watershed hydrological response, and coastal sedimentation levels during the period 2016–2025. The data used are multi- temporal Sentinel-2 Level-2A satellite images analyzed using the Normalized Difference Vegetation Index (NDVI) to identify the condition of mining land clearing and the Normalized Difference Turbidity Index (NDTI) to represent the level of sedimentation and turbidity of coastal waters. Spatial analysis was carried out based on watershed units to examine the upstream–downstream relationship between the intensity of mining land clearing and sedimentation responses in the estuarine zone. The results show that watersheds with a dominant low NDVI value tend to experience increased surface runoff and potential soil erosion, which in turn contributes to increased coastal sedimentation as indicated by relatively high NDTI values. These findings confirm a strong link between land cover changes due to nickel mining activities, watershed hydrological responses, and coastal sedimentation intensity. This research emphasizes the importance of a watershed-based approach in nickel mining environmental management and sedimentation impact mitigation efforts to maintain the sustainability of coastal ecosystems.
