Abstract

The existing condition of the Adi-adi Waste TPA still tends to be operated in the Open Dumping manner even though the construction of the TPA is designed with the concept of controlled landfill management. Therefore one of the aims of this research is to know the technical processing of Adi- adi Waste TPA from the planning and implementation aspects, as well as to design a development concept to increase work effectiveness in the landfill block area with the help of technological devices. This study uses a  qualitative method with a  descriptive approach. Methods of data collection through interviews, observation, and study of documents. In this research, it is known that the technical processing model tends to be open dumping ˆwhich only covers land 2-3 times in one fiscal year. The design of the development concept in the technical aspect of processing is the use of a Garbage Truck Vehicle Detection Sensor combined with direction guide lights in the Garbage Cell area that is being operated.

Abstract

The vulnerability of landslides that occur in the Sakuli area, Kolaka Regency is related to topographic conditions which are dominated by mountains and hills, for this reason, research is needed as an effort to determine the level of vulnerability and determine disaster mitigation efforts against the danger of landslides. This type of research is quantitative descriptive by looking at the influence of each variable to analyze landslide-prone areas. The method used in this research is experimental analysis with direct observation in the field. From the research results, the vulnerability level value for the slope parameter was 0.83; with soil texture 0.408; for faults 0.86; value for regolith 0.363; with geological conditions 0.628; with a rainfall value of 0.3 and land use of 0.6, the accumulated value is that the research area is at a very vulnerable level with a value of 3.989. Therefore, this area really needs structural and non-structural mitigation to be able to protect and reduce the potential for landslides.

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

Marshall Test Mix Asphalt PG 70 and Asphalt Pen 60/70. Marshall aims to determine the characteristic of the dough in the test object. In this case to know the values of durability (stability), melting (flow), & marshall Qouintient. The Marshall tool is a pressure sensor which is equipped with a proving ring with a capacity of 22.5 KN or 5000 IBS. The proving ring is equipped with a measuring watch which is useful for measuring the stability of the dough. Apart from that, there is still a flow meter to measure plastic melting, because the basic principle of the Marshall method is inspection of stability & melting (flow), and analysis of density & pores based on the dough that is formed. The dough design of the Marshall method was discovered by Bruce Marshall, & has been standardized by ASTM or AASHTO through several modifications, namely ASTM D 1559-76, or 27 AASHTO T T-245-90. The standard Marshall Test object is a cylinder with a diameter of 4 inches (10,16 cm) and a heigt of 2,5 inches (6,35 cm).

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.
