Abstract

Coastal damage due to abrasion can interfere with residents' livelihoods, especially those who work as fishermen. Beaches that experience abrasion will result in more severe beach damage if not addressed. Coastal dynamics caused by wave activity, tides, currents, and human activities cause shoreline changes. This study aims to determine the coastal abrasion disaster threat level in North Galesong District, Takalar Regency. The analytical method used is the analysis of coastal abrasion threat index data in coastal areas, including oceanographic data, namely wave height and current speed, ecological data, mangrove vegetation density, the physical environment, and the shape of the coastline and beach characteristics. Analysis of the data using the analysis table of disaster threat assessment issued by the Head of BNPB Regulation No. 2 of 2012 concerning General Guidelines for Disaster Risk Assessment. The study results have a high category of coastal erosion threat in the coastal area of Galesong Utara District, which is found in all coastal village areas. The high category level represents the high potential threat of coastal abrasion to the incidence of casualties and material losses on the coast of North Galesong District. It is necessary to build structural mitigation to maintain coastal stability in the form of longshore sedimentation retaining structures, abrasion absorbers, and, breakwater structures to reduce the rate of coastal abrasion.

Abstract

The research location is located in Tanggetada sub-district, Kolaka district, which is an area very close to laterite nickel mining sites. The determination of the research location was deliberately chosen at the nickel mining location, with the consideration that at that location the river was brownish red, and at that location there were many miners who did not carry out according to mining regulations. The method used is observational which is carried out at nickel laterite mining sites. by using a cross sectional approach that is both qualitative and quantitative. Based on the results of the data analysis that has been carried out, it can be explained that the distribution of heavy metal pollution in river water is the largest in the heavy metal Copper (Cu), namely 0.0108 mg/l, which is found at station 3, heavy metal lead (Pb), namely 0.0070 mg/l l found at station 4, heavy metal chromium (Cr) is 0.0038 found at station 6 downstream, heavy metal Cadmium (Cd) is 0.0028 mg/l found at station 3, heavy metal Hexavalent Chromium (Cr6+) is 0.0026 mg/l found at station 2. From the results of the analysis there are no heavy metals that exceed the quality standard (PP No. 82 of 2001). Meanwhile, the river sediment material produced the greatest amount of heavy metal Copper (Cu), namely 0.0229 mg/kg found at station 2, Heavy metal Cadmium (Cd), namely 0.0128 mg/kg found at station 5, Heavy metal Lead (Pb) namely 0.0177 mg /kg is found at station 1 upstream, heavy metal Chromium (Cr) is 0.0118 mg/kg found at station 6 downstream, heavy metal Hexavalent Chromium (Cr6+) is 0.0116 mg/kg found at station 6 downstream. From the results of this analysis there are no heavy metals that exceed the quality standards (USEPA, 2003).

Abstract

One of the uses of Buton Asphalt is LASBUTAG which is a road surface with a mixture of Asbuton, modifier and aggregate. Currently, heavy oil as a modifier is scarce in the market, so it is necessary to consider other alternatives as a modifier, one of which can be used, namely waste oil motor vehicle or other machinery. The aim of this study is to analyze the ideal modifier variation in Lasbutag blends using Lombah oil and diesel fuel as modifiers. This research is a quantitative research using experimental methods conducted in the laboratory. The use of the modifier with waste oil and diesel fuel for Lasbutag cold mix pavements can meet the Marshall characteristics required in the special Lasbutag specifications. The stability required in the Lasbutag special specifications is met by using a modifier content of 4.2% to 6.8%, VIM can be achieved at different modifier levels between 4.8% and 7.2%, Cavity Parameters Between Mineral Aggregates (VMA) can be achieved using modifiers from 4% to 7.0% and Melt Value (Flux) can be achieved using modifiers from 4% to 6 .2%. The cold-mixed Lasbutag characteristics required in the Lasbutag special specifications can be met using a modifier between 4.8% and 6.2%, so the most ideal modifier is achieved at 5.5%.

Abstract

The research location is located in Tinobu Village, Lasolo District, North Konawe Regency, which is a developing area and is known for its abundant natural wealth. Tinobu Port existed before Indonesia's independence, where Tinobu Port is tens of years old and has become an icon on the coast of North Konawe Regency, especially in Tinobu Village. Tinobu Port does not have any main facilities or supporting facilities that can facilitate activities at the port. Tinobu Port is widely used by local fishermen for loading and unloading of fish to be sold around the North Konawe Regency area and some are even sold as far as the city of Kendari. development after development has been carried out by the surrounding community as well as assistance from the local government so that at this time Tinobu Port already has a causeway with a length of approximately 400 (four hundred) meters, but due to the age factor, the condition of the causeway has also suffered a lot of damage. The purpose of this study was to evaluate the Existing Conditions of Tinobu Port, Lasolo District, North Konawe Regency in the form of several surveys conducted directly at the research location for future development purposes.

Abstract

The study area is located in the IUP of PT X, which covers an area of ± 1,210 ha. Administratively located in Bombana Regency, Southeast Sulawesi Province. Spatial data analysis in mapping the potential success rate of reclamation and environmental design is carried out based on geological criteria and remote sensing so that the impact of risks in the mining industry can be minimized. This study aims to map the potential success rate of post-mining land reclamation and environmental design in the study area based on spatial analysis with the Analytical Hierarchy Process (AHP) method. The geological criteria used in this study are lithological units, seismicity, hydrology (catchment area), vegetation density distribution, and hydrothermal alteration (iron oxide alteration and clay minerals). The data used in this study are the Kolaka sheet regional geologic map, DEM SRTM, Landsat 8 imagery, and company reports (lithology, reclaimed land openings). The data were analyzed to produce evidence maps of lithology, ranginess, catchment area, and vegetation density distribution using the NDVI technique and hydrothermal alteration using the band ratio technique, then spatial analysis was carried out using the AHP method. The result of this research is a map illustrating the potential success rate of reclamation and environmental design in the study area which is divided into 3 classes, namely: high potential area of 407.52 Ha (36.68%), medium potential area of 360.81 Ha (32.48%), and low potential area of 342.54 Ha (30.84%) of the total area. Based on the validation test of the reclaimed land opening area of 28.63 Ha that corresponds to the area with the result of a high potential success rate of about 89% of the total validation land opening area the results of this modeling are statistically acceptable.

Abstract

This study analyzes the performance of the Losari Wastewater Treatment Plant (IPAL) in reducing the levels of the pollutants Nitrite (NO2¯) and Phosphate (PO4³¯) in domestic wastewater using the Moving Bed Biofilm Reactor (MBBR) method. The issue of domestic waste in large cities, particularly in coastal areas like Losari, is becoming increasingly complex due to high population density and tourism activities, which require an effective waste treatment system that meets environmental quality standards. The main objective of this research is to analyze the chemical parameters (Nitrite and Phosphate) in the treatment of domestic wastewater using the MBBR method at the Losari wastewater treatment plant, as well as to analyze the optimization of wastewater treatment using this method. This research uses an observational method with a quantitative approach to measure the performance of MBBR in reducing pollutant levels, with wastewater samples taken from the inlet, MBBR tank, and outlet. The testing was conducted at the South Sulawesi Provincial Environmental Agency Laboratory. The test results show that the MBBR process is effective in reducing phosphate, with all testing points showing phosphate concentrations below the quality standard of 2 mg/L. However, for the nitrite parameter, although the levels at the inlet point are within the safe limits, there is an increase in levels at the outlet point (0.628 mg/L), which exceeds the quality standard of 0.6 mg/L, indicating that the nitrification-denitrification process is not yet optimal. Overall, the Losari wastewater treatment plant system with MBBR has successfully managed phosphate well, but further optimization is needed for nitrite processing to meet the established quality standards.

Abstract

The handling of human hair waste is still not optimal, as it is often discarded or burned, leading to environmental pollution. This research aims to utilize human hair waste as a mixture in normal concrete, resulting in a fiber-reinforced concrete product with marketable value, providing a more beneficial use compared to simply being disposed of or burned. The purpose of this study is to analyze the mechanical properties of concrete using human hair fibers. The mechanical properties to be analyzed include compressive strength, tensile splitting strength, and flexural strength. This research is based on laboratory experiments. The variations in the amount of fiber used in the study are 0.25%, 0.5%, 1%, and 1.5% of the cement weight in the concrete mix. Based on the results of mechanical property testing, it can be concluded that the optimal addition of 1% human hair fibers yielded a compressive strength of 22.86 MPa, tensile splitting strength of 2.69 MPa, and flexural strength of 4.13 MPa.

Abstract

Sustainable mining requires the implementation of Good Mining Practice (GMP) principles to minimize negative environmental impacts, particularly on tailing disposal sites. One important aspect of GMP is post-mining land rehabilitation, especially on tailing sites that have the potential to cause ecosystem damage. Tailing-affected lands require restoration involving plants capable of adapting to extreme environmental conditions. This study aims to apply GMP by utilizing angiosperm vegetation for land rehabilitation at the Research Center Mile 21, PT. Freeport Indonesia. Tailing-contaminated lands need recovery through plants that can thrive in harsh conditions. Angiosperm plants were selected for their ability to improve soil structure, reduce erosion, and enhance soil fertility. This research evaluates the effectiveness of angiosperm vegetation in accelerating soil recovery and supporting ecosystem sustainability. The findings are expected to provide valuable information and recommendations for more effective tailing site rehabilitation management and serve as a reference for environmentally friendly mining practices in the future.
