Abstract

The Semilir Formation located in Ngoro-Oro, Gunungkidul, has significant lithofacies diversity, reflecting dynamic depositional conditions in the past and indicating a recurring depositional pattern. The limitations of stratigraphic and geostatistical information are the main reasons for this research. This study aims to identify the characteristics of lithofacies in the Semilir Formation, Ngoro-Oro, Gunungkidul, and analyze the relationship between facies through the chi-square statistical test. In addition, the pattern of lithofacies repetition and transition is evaluated using the Markov chain method to determine the probability of lithofacies repetition and predict the stratigraphic sequence at the research location. The research was conducted on ancient rock outcrops along the Prambanan-Wonosari alternative route located in Ngoro-Oro Village, Patuk District, Gunungkidul Regency, Daerah Istimewa Yogyakarta Province by conducting stratigraphic measurements with a thickness of 78 meters using Jacob stuff then continued with geostatistical analysis using the Markov chain method. This method will provide an understanding of the prediction of lithofacies transition patterns in the research area. The research results reveal that the lithofacies at the study location consist of lithology composed of sandstone interbedded with claystone and tuff, sandstone interbedded with claystone with siltstone inserts, and sandstone interbedded with siltstone with claystone inserts. The results of the Markov chain statistical calculation of lithology or lithofacies have a non-random transition pattern

Abstract

This position paper narrates how the author's position based on the hot issue of nurturing the COVID-19 pandemic. The pros and cons of the "New Normal" concept [kenormalan baru] are argumentatively illustrated through a literature search. The primer information from WHO, policymaker, and researchers contributed to the discussion. Health protocols become the rules mentioned in implementing a new normal, namely by reducing physical contact with others. Nevertheless, the new normal policy is no less low and dangerous, is the insufficient appreciation of science, especially revelation. Thus, the concept of the new normal has not valued except just taking material and economic benefits.

Abstract

Indonesia has many environmental problems, especially those related to mining. It becomes essential to provide environmental education to the younger generation. However, the environmental education curriculum has not been explicitly found in the body of formal education in Indonesia. The study area is in Gunungkidul Regency, Indonesia where the limestone mining industry has expanded in almost all areas. The purpose of this study is to assess the environmental impacts of limestone mining activities and align the possible integration of environmental education in the study area. To gather data about the environmental impacts of limestone mining activities, a desktop study, field investigation, and interviews with local communities were conducted. Analysis of the Indonesian curriculum and interviews with elementary school teachers were conducted to align the possible integration of environmental education. The environmental impacts of limestone mining activities in the study area include air pollution, water contamination, drought, soil erosion, and road damage. We provide some suggestions for learning materials including an Introduction to environmentally friendly mining activities (Science subjects, grade 4, thematic 3), an Introduction to air pollution impacts in the mining area on human breathing (Science subjects, grade 5, thematic 2), and Introduction about mining activities impacts on the air, water, and soil (Science subjects, grade 5, thematic 8). It is recommended that teachers not only teach theory but also practice and environmental observation.

Abstract

Gunungkidul Regency, one of Indonesia's karst regions, frequently experiences droughts. This study aims to investigate the causes of drought disasters and provide adaptation strategies for disasters that may occur near karst areas in Gunungkidul Regency. We used Google Scholar to identify drought causes on the study site. The next stage is making appropriate adaptation strategies using a qualitative and comparative analysis technique. The three main components that cause drought disasters in Gunungkidul Regency include climate characteristics, hydrogeological characteristics, and anthropogenic factors. Some proposed adaptation strategies to address the impacts of drought disasters include planting crops with low water requirements, adopting conservation agriculture and utilizing organic farming, applying structural adaptation strategies, developing agroforestry, giving farmers financial assistance, paying compensation to drought-affected families, distributing knowledge about drought adaptation strategies, reducing family food demand, suggesting seasonal migration, and reducing livestock. Working with multiple stakeholders is essential to putting these adaptation strategies into action.

Abstract

Abstrak : Krisis air bersih di Desa Banyurejo, Kapanewon Tempel, Sleman, merupakan fenomena yang menarik untuk dikaji. Secara kenampakan permukaan wilayah ini memiliki potensi air tanah yang cukup. Namun, kondisi di lapangan menunjukkan keterbatasan ketersediaan air bersih. Pengabdian ini bertujuan untuk memahami kondisi bawah permukaan yang mempengaruhi keberadaan air tanah melalui kajian geofisika. Metode yang digunakan adalah geolistrik dengan konfigurasi Wenner–Schlumberger. Hasil pengukuran menunjukkan nilai resistivitas berkisar antara 3,7 Ω·m hingga 387 Ω·m yang mengidikasikan potensi saturasi air tanah. Variasi distribusi nilai   resisitivitas secara lateral mencerminkan heterogenitas litologi bawah permukaan khususnya dibagian Banyurejo sisi selatan. Kondisi tersebut diduga membatasi kemenerusan akuifer dan meningkatkan kerentanan terhadap penurunan ketersediaan air tanah. Alternatif yang ditawarkan yaitu peningkatan sistem resapan dan pengaturan tata ruang.Abstract: The clean water crisis in Banyurejo Village, Tempel Subdistrict, Sleman, presents a significant case for investigation. Although the surface characteristics suggest adequate groundwater potential, field observations reveal restricted access to clean water. In light of these conflicting indicators, this study seeks to analyze subsurface conditions affecting groundwater availability using geophysical methods. Specifically, the geoelectrical method with the Wenner–Schlumberger configuration was employed. Measurement results showed resistivity values ranging from 3.7 Ω·m to 387 Ω·m, indicating potential groundwater saturation. Furthermore, variations in the lateral distribution of resistivity values reflect the heterogeneity of subsurface lithology, particularly in the southern part of Banyurejo. As a result, this condition is thought to limit the continuity of the aquifer and increase vulnerability to declining groundwater availability. To address these issues, alternatives offered include improving the infiltration system and spatial planning.

Abstract

Acid mine drainage (AMD) is mining waste that has high acidity and dissolved metal content, especially iron (Fe), which has the potential to pollute the aquatic environment. This research aimed to evaluate the performance of coconut shell activated charcoal and local composite-based adsorbents (active charcoal–clay–zeolite) in reducing Fe concentrations in AMD. The research was conducted using two types of samples: real AMD collected from the mine site and synthetic AMD prepared in the laboratory using a FeSO₄·7H₂O solution. The composite adsorbent was tested using real AMD (baseline pH 2.6; Fe 42.75 ppm), while activated charcoal was tested on synthetic AMD (baseline pH 4.7; Fe 40.37 ppm). The main variables observed were dissolved Fe concentration and pH changes at various contact time variations. Analysis of Fe concentrations was carried out using AAS, while pH was measured directly with a pH meter. Adsorbent characterization was performed with BET to identify the specific surface area of the adsorbents. Results showed that activated charcoal was able to increase pH to 8.6 and decrease Fe to 0.04 ppm (99.9% efficiency). The primary mechanism of Fe reduction is dominated by Fe(OH)₃ precipitation, which occurs due to an increased pH. In contrast, the composite produced a final pH of 4.3 but still decreased Fe to 0.52 ppm (98.8% efficiency). BET analysis showed that although activated charcoal had a greater surface area, the composite maintained better pore stability after adsorption. The integration of the two has the potential to enhance the adsorption effectiveness and stability in the field for the remediation of acid mine drainage.
