Abstract

One aspect and factor that is very important in the blasting stage is rock fragmentation, which has a direct impact on drilling costs, blasting costs and operational economics, both loading, transportation and crushing. As time progresses, new technological advances for the application of blasting have developed. This technology is to computerize blast design and predict the results of the explosion, which is rock fragmentation. Many factors influence rock fragmentation, such as the nature of the rock mass, geological location conditions, explosion and fracture parameters present in place, so it is difficult to predict completely. However, empirical models to predict the size distribution of rock fragmentation have been developed. In this study, Monte Carlo simulation as a rock fragmentation simulator based on the Kuz-Ram fragmentation model has been developed to predict fragmentation size distribution. The results obtained from this Monte Carlo simulation can be said to be quite good when compared with the actual data fragmentation obtained from field conditions.

Abstract

Urbanization has significantly increased alongside economic growth and social change, bringing both opportunities and challenges, particularly in environmental and social contexts. This study aims to analyze the environmental and social impacts of urbanization in relation to sustainable development, using a comprehensive literature review of 50 relevant articles published between 2019 and 2024. The analysis focused on two main themes: the environmental and social consequences of urbanization and strategies for achieving sustainability. The results reveal that urbanization contributes positively to economic growth, access to education, and healthcare, but negatively impacts the environment and social equity. Key challenges include pollution, waste generation, climate change, limited affordable housing, and social inequalities. Notable strategies for sustainable urbanization include effective waste management, clean energy adoption, and green city initiatives. Research from Jambi and Serang highlights community involvement in waste reduction and the promotion of renewable energy as vital components for urban sustainability. The study concludes that sustainable urban planning, emphasizing integrated solutions across environmental, economic, and social domains, is crucial for mitigating urbanization's negative impacts. Collaborative efforts among policymakers, local communities, and researchers are essential to create inclusive and resilient cities aligned with sustainable development goals.

Abstract

Pengelolaan sampah organik di lingkungan sekolah menjadi bagian penting dalam upaya membangun kesadaran lingkungan dan penerapan prinsip berkelanjutan sejak usia dini. Penelitian ini menggunakan metode kajian literatur (literature review) dengan menelaah sejumlah artikel ilmiah terbitan lima tahun terakhir yang relevan, baik dari jurnal nasional terakreditasi (SINTA) maupun jurnal internasional bereputasi (Scopus). Hasil kajian menunjukkan bahwa edukasi lingkungan yang diintegrasikan ke dalam kegiatan belajar, seperti pelatihan komposting dan budidaya maggot, dapat meningkatkan pemahaman dan keterlibatan siswa dalam pengelolaan sampah. Di sisi lain, penerapan ekonomi sirkular di sekolah turut mendukung terciptanya sistem pengelolaan sampah yang produktif dan berkelanjutan. Keberhasilan program ini bergantung pada keterlibatan aktif seluruh elemen sekolah, pendekatan kontekstual, serta dukungan kebijakan sekolah. Oleh karena itu, strategi pengelolaan sampah organik berbasis edukasi dan ekonomi sirkular dapat menjadi model pembelajaran lingkungan yang efektif dan aplikatif di tingkat pendidikan dasar dan menengah.

Abstract

Landslides are a recurrent hazard in West Sumatra, driven by steep slopes, high rainfall, and expanding human activity on unstable terrain. This study assesses landslide susceptibility in IV Koto, Matur, and Tanjung Raya Subdistricts of Agam Regency, West Sumatra using a Geographic Information System (GIS) framework. Slope gradients were derived from DEMNAS (Digital Elevation Model Nasional), land use data were reclassified based on expected stability effects, and rainfall statistics were discretized into intensity classes. These standardized layers were integrated through a weighted overlay to produce a susceptibility surface, subsequently partitioned into two classes: vulnerable and very vulnerable. The results highlight elongated belts of very vulnerable terrain where steep slopes coincide with high rainfall and disturbed land covers such as settlements, open fields, and mining areas. Cross-sectional profiles with gradients of   40.9-56% confirmed the geomorphic plausibility of the mapping. The outputs provide actionable guidance for spatial planning, disaster preparedness, and conservation, while offering a transparent baseline for more advanced susceptibility models as data availability improves.

Abstract

This study aims to examine the impact of AAT on the water quality of the Purian River and its implications for communities that depend on this water source. Acid mine drainage, which is formed due to the oxidation of sulfide minerals, can reduce water quality, potentially affecting the health and economy of the user community. The research methods applied include quantitative and qualitative approaches. The analysis was carried out using a correlation test to measure the relationship between water quality between the point of compliance and the Parambahan River, and the Chi-Square test was used to evaluate the relationship between seasonal mining activities and health problems experienced by respondents. In addition, a survey was conducted to explore local community perceptions regarding the impact of river water. The results of the study indicated mild pollution in several water quality parameters, especially TSS and heavy metals, which exceeded the quality standard limits. Water quality status was measured using the Pollution Index based on PP No. 22 of 2021 and Kepmen LH No. 113 of 2003. The results showed that most samples were classified as mild pollution. Correlation analysis indicated that AAT was not the only factor causing pollution, due to seasonal mining activities and the contribution of water use for livestock farming practices. The conclusion is that waste management carried out by PT. AICJ meets government quality standards, at 66.67%, but respondents still feel negatively affected by mining activities.

Abstract

The mining industry, especially in the crushing plant area, faces serious problems related to noise that can reach more than 85 dB(A). Noise exposure for 8 working hours is at risk of causing temporary or permanent hearing loss (NIHL), which is a common occupational disease found in crushing plant workers. The type of research used in this study is descriptive analytical with a cross-sectional approach. Data collection techniques were carried out by measuring noise levels in the Crushing Plant area and distributing questionnaires to obtain data on the hearing health of mining workers. The location of this study was at CV. Tekad Jaya. The results of the noise level study at CV. Tekad Jaya showed an alarming situation, where 50% of the 14 measurement points exceeded the threshold of 85 dB, with a peak of 96.86 dB at point Std 10. The health impacts were clearly visible with 46.2% of workers experiencing headaches and 61.5% having difficulty communicating, even though the majority had used PPE. The combination of distance and vegetation has proven effective in reducing noise up to 76 dBA at a distance of 95 meters. The metal plate enclosure system showed positive results, reducing noise levels to 83 dBA inside and 67 dBA outside the building. Recommended control strategies include a zoning system with double protection, worker rotation, and health monitoring for areas >85 dBA, and a preventive approach for zones <85 dBA.

Abstract

Public health reflects a complex and dynamic interaction between various determinants, where environmental conditions play a crucial role in influencing disease distribution patterns. The type of research used is qualitative through a descriptive approach. Data from this study were collected through medical records of patients visiting the Lubuk Alung Health Center during the period January to December 2024. The data collection process was carried out by health center officers by accessing medical records to document the type of disease and the number of cases based on their respective work areas. Furthermore, each case of disease was classified according to the type of disease and the patient's area of ​​residence. This study was conducted in the work area of ​​the Lubuk Alung Health Center, Padang Pariaman Regency, West Sumatra. The results of this study found that the distribution of the ten most common diseases was greatly influenced by local environmental conditions in seven villages, namely Air Tajun, Balah Hilir, Lubuk Alung, Pasir Lawas, Pangkalan Kasiak, Sei Abang, and Singguling. The disease with the highest number of cases was ARI (393 cases), followed by Diabetes Mellitus (355 cases), Hypertension (196 cases), Schizophrenia (168 cases), Dyspepsia (135 cases), Cephalgia (35 cases), Febris (56 cases), Skin Disease (45 cases), Heart Disease/HT (50 cases), and Other Diseases (51 cases). Balah Hilir and Pangkalan Kasiak villages showed the highest prevalence of diseases in general, with Balah Hilir recording the highest cases of ARI (97), Diabetes Mellitus (63), Dyspepsia (30), and Heart Disease/HT (11), while Pangkalan Kasiak dominated cases of Diabetes Mellitus (79), ARI (85), and Hypertension (65). Sei Abang also had high figures for ARI (67), Schizophrenia (17), and Skin Disease (12). In contrast, villages such as Pasir Lawas and Lubuk Alung had relatively lower cases of most diseases. This uneven distribution of disease indicates the strong influence of local environmental factors such as air quality, sanitation, lifestyle, and health infrastructure, so that specific area-based interventions are needed to improve overall public health.

Abstract

This study aims to analyse the implementation of the Mining Safety Management System (SMKP) in the andesite quarry crushing area of PT. X, Subang Regency, West Java. The study uses a descriptive mixed methods approach that combines direct observation, structured interviews, and questionnaire surveys of workers in the crusher area using purposive sampling. The data were analysed using the Miles & Huberman model for qualitative data and descriptive statistics for quantitative data, with triangulation for validation of the results. The results showed that the implementation of SMKP at PT. X was still suboptimal. The overall criterion fulfilment rate reached 54.74% of the maximum total of 292 points, with significant variations between elements. The implementation element showed the best performance (54.31%), followed by organisation and personnel (54.55%), and monitoring and evaluation (60.42%). Conversely, three critical elements showed alarming conditions: documentation (33.33%), planning (37.93%), and management review (46.15%). This imbalance indicates a weak strategic planning system, procedural documentation, and continuous evaluation by top management. The study concluded that PT. X requires comprehensive and systematic improvements, prioritising documentation, safety programme planning, and management review to build the foundation of an effective mining safety management system in accordance with the regulations of the Ministry of Energy and Mineral Resources.

Abstract

Pada PT Hutamas Koado masih terdapat beberapa beberapa jalan yang belum sesuai standar seperti, grade yang terlalu tinggi yaitu 13% melebihi batas maksimum yang ditetapkan perusahaan yaitu 8%, dan masih banyak lebar jalan yang belum sesuai aturan sehingga alat terjadi antrian ketika truck melintas secara bersamaan, sehingga menyebabkan cycle time dari alat angkut bertambah. Penelitian ini mengevaluasi kesesuaian geometri jalan tambang PT Hutamas Koado terhadap standar Kepmen ESDM 1827/K/30/MEM/2018. Hasilnya menunjukkan dari 100 segmen jalan (73 lurus, 27 belok), banyak yang tidak memenuhi kriteria ideal: (1) 19 segmen jalan lurus lebih sempit dari lebar ideal 13 m, (2) seluruh jalan belok tidak mencapai lebar teoritis 22 m, (3) 32 segmen memiliki cross slope tidak ideal (standar 13 cm), (4) hanya 1 segmen yang memenuhi superelevasi ideal 0,9 m, dan (5) 5 segmen melebihi kemiringan maksimum 10% (mencapai 13,146%). Temuan ini mengindikasikan ketidaksesuaian signifikan antara desain jalan tambang dengan standar yang berlaku.
