FACTOR OF SAFETY AND PROBABILITY OF FAILURE ASSESSMENT OF ROCK SLOPES IN ARTISANAL KAOLIN MINE USING LIMIT EQUILIBRIUM METHOD AND MONTE CARLO SIMULATION

Rianse, Mohammad Suriyaidulman
Abstract: This study aims to evaluate the stability of three rock slopes in an artisanal kaolin mine in Semin, Gunungkidul, Yogyakarta, Indonesia, using deterministic and probabilistic approaches, and to identify the geotechnical… parameters most influencing slope stability. The evaluation is conducted in compliance with Indonesian Mining Regulation (Kepmen ESDM No. 1827 K/30/MEM/2018) to provide quantitative geotechnical evidence for a mine that has been operated without prior formal geotechnical assessment. Field data were collected using the scanline method to characterize rock mass discontinuities. Laboratory tests comprising direct shear and physical properties tests were conducted to determine cohesion (c), friction angle (ϕ), and unit weight (γ) for each slope. Seismic coefficient (ks = 0,0913) was incorporated as a dynamic loading parameter. Slope stability was analyzed using the General Limit Equilibrium (GLE) method to obtain the deterministic Factor of Safety (FoS). Monte Carlo simulation (N = 10.000 iterations) was applied to determine the Probability of Failure (PoF), coefficient of variation of FoS (CoV), and reliability index (β). Sensitivity analysis was performed to quantify the contribution of each geotechnical parameter to FoS reduction. Results show that FoS values ranged from 2,019 (Slope III) to 10,55 (Slope II), all exceeding the regulatory minimum of 1,1. The PoF was 0,00% for all three slopes, well below the maximum allowable limit of 25%, with reliability indices ranging from 5,70 to 31,38. The CoV of FoS ranged from 3% to 9%, indicating low dispersion in stability outcomes despite parameter variability. Sensitivity analysis identified cohesion as the most dominant parameter in Slopes I and II, contributing 28% and 31% to FoS reduction respectively, while Slope III exhibited near-equal contributions from cohesion (20%) and friction angle (21%), reflecting its lower shear strength conditions. All three slopes satisfy the acceptance criteria of Kepmen ESDM No. 1827 K/30/MEM/2018 under current geotechnical and geometric conditions. The combined deterministic-probabilistic approach provides a more comprehensive slope safety assessment than deterministic analysis alone and is recommended for application in artisanal kaolin mining operations. Cohesion is identified as the critical parameter to be monitored and preserved to maintain slope stability.

Pratama, Dean Hadi, Yohana, Corry, Parimita, Widya
Abstract: This study aims to analyze the influence of Career Development, Culture Value, and Emotional Intelligence on Personal Branding with Self-Efficacy as a mediating variable in State Civil Apparatus (ASN) in Tegal City Government.… nment. The study used a quantitative approach with a survey method by distributing questionnaires to 360 ASN consisting of Civil Servants (PNS) and Government Employees with Work Agreements (PPPK). The sampling technique used proportionate stratified random sampling, while data analysis was carried out using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with the help of SmartPLS 4. The results showed that Career Development, Culture Value, and Emotional Intelligence had a positive and significant effect on Self-Efficacy. In addition, these three variables also have a positive and significant effect on Personal Branding. Self-Efficacy was proven to have a positive and significant effect on Personal Branding and was able to significantly mediate the influence of Career Development, Culture Value, and Emotional Intelligence on Personal Branding. The coefficient of determination value shows that the model is able to explain 70.1% of the variation in Self-Efficacy and 76.8% of the variation in Personal Branding. The findings of this study indicate that strengthening the career development system, internalizing organizational cultural values, and increasing emotional intelligence can increase the self-confidence of ASN which ultimately strengthens Personal Branding in carrying out tasks and public services. This study provides an empirical contribution to the development of public sector human resource management, particularly in efforts to improve the professionalism and image of the apparatus through strengthening internal organizational factors.

Azzahra, Nabila, Vitratul Ilahi, Muhamad Sholichin
Abstract: Air bersih yang aman dari kontaminasi mikrobiologis dan parasitologis merupakan prasyarat utama kesehatan masyarakat, namun capaian akses air minum aman di Indonesia masih jauh tertinggal dibandingkan akses air minum layak&#8230; ak secara umum. Penelitian ini bertujuan memetakan tren tahun publikasi, sebaran jenis sumber air, sebaran wilayah, dan peluang riset kontaminasi mikrobiologis dan parasitologis pada sumber air bersih di Indonesia melalui analisis literatur. Penelusuran dilakukan pada basis data Google Scholar menggunakan Harzing's Publish or Perish dengan kata kunci kontaminasi mikrobiologis dan cemaran bakteri air bersih Indonesia, dibatasi pada rentang tahun 2020 hingga 2025. Setelah skrining judul, pemeriksaan duplikasi, dan pengecekan kelengkapan metadata mengikuti alur seleksi bergaya PRISMA, diperoleh 115 artikel yang memenuhi kriteria kelayakan untuk dianalisis. Hasil menunjukkan tren publikasi meningkat tajam pada 2024 dan 2025, menyumbang lebih dari separuh total artikel. Air minum umum dan depot air minum isi ulang mendominasi objek penelitian dengan proporsi 73,9%, sementara Coliform dan Escherichia coli menjadi parameter yang paling banyak diuji sebesar 66,1%, umumnya menggunakan metode Most Probable Number. Wilayah penelitian masih terkonsentrasi di Pulau Jawa, sedangkan tidak satu pun artikel yang secara eksplisit meneliti kontaminasi parasitologis ditemukan sepanjang periode tersebut. Temuan ini menunjukkan penelitian kontaminasi air bersih di Indonesia masih terkonsentrasi secara tematik, objek, dan wilayah, sehingga membuka peluang riset yang luas pada aspek parasitologis, sumber air non-komersial, serta wilayah di luar Pulau Jawa.
