Abstract

Flexible pavement is very weak against waterlogging because water can loosen the bond between aggregate and asphalt. Porous Asphalt has lower durability because it has high pores so that it can be passed by water. Poor bonding of asphalt and aggregate will cause stripping. This peeling can cause water absorption which will eventually accelerate road damage. Derbo 401 anti-peeling material is one of the new breakthroughs, in the form of additives that can change the properties of aggregates and asphalt, increase adhesion and bonding, and reduce the negative effects caused by water so as to produce a mixture of asphalt with high adhesion. The purpose of this study was to determine the effect of adding anti-stripping agent type Derbo-401 to the permeability value and to determine the resistance of the porous asphalt mixture with the addition of anti-striping agent type Derbo-401 in the Cantabro test and to determine the microstructure of the porous asphalt mixture. Using the REAM-2008 Specification. Based on the results of the study, the Permeability Coefficient Value of the porous asphalt mixture was 0.254 cm3/sec. the lowest percentage Derbo 0.4%, the lowest Cantabro Loss value at 0.3% addition percentage gets an average value of 6.13%, Has met the required specifications max 15%. The elements that make up the porous asphalt mixture with the addition of Derbo percentage are more in the elements Si (silicon) 19.93%, Ca (calcium) 21.12%, S (sulfur) 8.45%, Fe (ferrum) 8.80%, K (potassium) 2.42% and the other elements are less.

Abstract

In relation to the development of the quality of the transportation system, road pavement technology will gradually develop and be updated in terms of the quality of the transportation infrastructure currently being developed by porous asphalt. Porous asphalt is an asphalt mixture that is designed to have a higher porosity than other types of pavement. it is obtained because the porous asphalt mixture uses a smaller proportion of fine aggregate than other mixtures. In addition to asphalt, there are aggregates both coarse and fine and filler is one of the components in a road pavement construction that has a big role. In order to increase its stability, the use of fine fractions including filler in the mixture proportion should be more. Class C coal fly ash is one of the non-organic and non-plastic materials that can be used as a filler in porous asphalt mixtures and is expected to increase its strength. The purpose of this study was to analyze the effect of using flyash on a porous asphalt mixture on the value of the marshall characteristics and the value of weight loss. The results of this study discuss the marshall test on variations in coal flyash waste 0%, 2%, 3%, 4%, 5%, and 6% using the REAM specification, for the VMA value the percentage of coal flyash waste all meets the specifications specified. has been required, for the VIM value only the percentage of 4% that meet the specifications and 0%, 2%, 3%, 5%, and 6% do not meet the required specifications.

Abstract

Asbuton, a natural asphalt source on Buton Island in Southeast Sulawesi, is one of Indonesia's potential sources of natural wealth. As a road pavement material, LASBUTAG still has many weaknesses. This is especially true for cold LASBUTAG mixtures, which are only suitable for highways with light traffic. To mix Asbuton in cold conditions, a modifier is needed, the data of which is rare on the market, so other alternatives need to be considered as a modifier. In this research, we will try to use a mixture of waste oil and diesel as a modifier. The use of waste oil in this research is by looking at the development of the volume of waste oil. which continues to increase along with the increase in the number of motorized vehicles and motorized machines. The spread of oil waste is very widespread from big cities to rural areas throughout Indonesia. Waste from lubricating oil is included in B3 waste which needs special treatment in its processing. The aim of this research is to analyze the optimum asphalt content of cold Lasbutag mixtures with modifier materials from waste oil and diesel. From the results of this research, the Optimum Asphalt Content (KAO) in the Lasbutag Wearing Course (WC) mixture was 6.30% of the total mixture weight. Based on regression analysis, asphalt content can produce stability of 704.464 kg, flow of 3.078 mm, Vim of 4.467%, VMA of 17.077% and IKS of 78.763%. These values have met the requirements set out in the 2006 Special Lasbutag specifications.

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

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.

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.
