Abstract

This community service activity aimed to improve the capacity of Micro, Small, and Medium Enterprises (MSMEs) in Paropo Village, Panakukang District, Makassar City, to face the challenges of the digital era. Training and education are focused on two main aspects: digital marketing strategies and business financial management. The implementation method included a participatory approach through interactive training sessions, simulations, group discussions, and direct mentoring. The results demonstrated an increase in participants' understanding and skills in using social media and other digital platforms for product promotion and marketing. Furthermore, participants gained practical knowledge in simple financial record keeping, cash flow management, and short- and long-term financial planning. Evaluation of the activity, conducted through pre- and post-tests, demonstrated significant improvements in participants' knowledge and skills. It is hoped that this activity will have a sustainable impact on the development of participants' businesses and strengthen the competitiveness of MSMEs in the region. This activity also opens up opportunities for further collaboration with the local government and related institutions in digital-based MSME development.

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.

Abstract

The research location is located at IUP PT. IFISHDECO, Tbk (122.168° - 122.204° East Longitude (BT) and 4.371° - 4.404° South Latitude (LS), Tinanggea, South Konawe Regency, Southeast Sulawesi Province.. The study aims to determine the surface flow direction and catchment area model at nickel mining sites. The data is in the form of topographic data measured with a total station, by conducting spatial analysis with Quantum GIS (QGIS) and remote sensing with the Strahler method in determining the river network. The results of research conducted at the research location obtained 3 catchment areas, namely Catchment 1 covering an area of 19,021 Ha, catchment 2 covering an area of 32,691 Ha and Catchment 3 covering an area of 59.77 Ha which can be used in further analysis in the mining drainage system.

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.
