Abstract

Vulnerability is the inability of an individual or community group to minimize the impact caused by a hazard. Information about the level of vulnerability is essential to reduce the risks and effects caused by a disaster. Assessment of the level of vulnerability of threatened areas is carried out to minimise losses and the population exposed to disasters. This study aims to determine the level of vulnerability to coastal abrasion in North Galesong District, Takalar Regency. The analytical method used is the vulnerability index of coastal areas consisting of population components, namely population density and vulnerable groups, economic components, low-income families and anglers, physical components in the form of building density and ecological features in the form of mangrove vegetation. Analysis of vulnerability index data using the vulnerability assessment table issued by the Regulation of the Head of BNPB Number 2 of 2012. The overall results of the research are the vulnerability level of coastal villages in North Galesong District is in the high category. The category of high vulnerability is a condition of a community or society that leads to or causes a high inability to deal with the threat of coastal erosion in the North Galesong District. Vulnerability reduction activities can be carried out by increasing public understanding, especially vulnerable groups and poor fishers groups, through training and socialization activities regarding potential disaster threats, the driving factors for their occurrence and the risks. Socialization of the potential danger of abrasion and extreme waves for fishers is necessary to increase knowledge in dealing with disaster threats. Socialization can be done by inviting anglers to disaster management activities.

Abstract

In South Sulawesi, Wajo Regency is one of the areas prone to flooding during the rainy season. Floods that occur in the area cause inundation. The inundation that occurred was caused by the overflow of Lake Tempe. This research was conducted in Laelo Village, Tempe District, which is located around the Tempe Lake Coast. This location was chosen purposively with the consideration that the area has become a frequent flood in the western part of the kelurahan (the part near the lake). The village has a low contour in the west and high in the east. The research design is descriptive and qualitative which aims to describe the state or status of the phenomenon. The purpose of the research is to analyze the forms of adaptation and mitigation that will be carried out by communities in flood-affected areas. This research uses field surveys, in-depth interviews, making field notes, and documentation. The data collection method was carried out using purposive sampling because the desired sample in the study was only people living in the coastal area of the lake, namely in Laelo Village which was only affected by flooding, not the entire Laelo Village community. Data analysis techniques in qualitative descriptive research are carried out with interactive analysis in the form of cycles. Data analysis was carried out simultaneously with the implementation process of data collection. The results of interviews with the community show that they understand that flooding is an ordinary natural phenomenon which is an overflow of a lake, but they do not know why there is a flood. Some people who live on the shores of the lake feel that almost every year they are exposed to floods from the lake. Where the form of adaptation they do is to raise the pole of the house and prepare a boat that is moored under the house to be used as a means of transportation in the event of a flood. Several forms of mitigation that have been carried out are water hyacinth retaining embankments, and making taller bridges with concrete connecting roads from house to house. Information has been found regarding evacuation signs with the evacuation route installed, the mosque is used as a place to disseminate information related to the incident and development of the flood. It is better to form a disaster-resilient village in the area to create an area that is more prepared to face disasters.

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 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.
