Abstract

The landslide near the PT Molindo Incinerator Unit poses a significant threat to the facility’s structural integrity. Without immediate mitigation measures, the incinerator building is at risk of collapse, potentially impacting adjacent settlements due to cascading structural failures. To reduce the risk of further instability, urgent geophysical investigation is required to characterize the subsurface lithology and assess the groundwater table conditions. A geoelectrical resistivity survey was conducted using the Schlumberger configuration across 8 measurement points along a 100-meter survey line, with 10-meter electrode spacing. The resistivity measurements ranged from 3.30 to 25 Ωm, which were interpreted as clay-rich layers; 26 to 167 Ωm, corresponding to sandy clay; and 167 to 15,944 Ωm, indicating bedrock. The potential slip zone is interpreted at an average depth of 20 to 25 meters, indicated by very low resistivity values with resistivity values between 3.30 and 25 Ωm. Field observations confirmed that the landslide materials predominantly consisted of clay soils, distributed within two distinct layers beneath the incinerator unit. The combined depth of the clay and overlying sandy layers was estimated to reach approximately 20-25 meters from the ground surface. To ensure the effectiveness of structural mitigation, a retaining wall must be designed to extend beyond this depth threshold. Numerical simulations using Slope/W software indicated that soil nailing techniques yielded safety factors ranging from 1.32 to 1.81 under static conditions and 1.22 to 1.43 under dynamic conditions. Predicted deformations ranged from 0.01 to 0.02 meters (static) and 0.02 to 0.03 meters (dynamic). These results suggest that soil nailing is a viable reinforcement method to stabilize slope movements, particularly during periods of high rainfall. Additional recommended mitigation strategies include the installation of surface and subsurface drainage systems to control water flow, constructing retaining structures to serve as physical barriers to soil movement, and using vegetative cover to enhance slope stability.

Abstract

The drought in Banyol Hamlet, Malang Regency, severely impacts community sustainability. This problem can be overcome if the hamlet has a groundwater source; theoretically, groundwater can be detected using geoelectric resistivity. This research aims to investigate the existence of aquifer layers in Banyol Hamlet, Malang Regency, using the resistivity method Schlumberger configuration. Resistivity data was measured at 5 points with a track stretch of 400 m and a distance between electrodes of 5 m; then, three parallel measurement points were interpolated into a 2D cross-section. Based on the analysis, the presence of the aquifer is considered to be in the breccia tuff layer because the resistivity value is lower than usual in this layer. So, we assume that the tuff breccia rocks can act as an aquifer in the study area. The results of the 2D cross-section show that the shallow aquifer is found at a depth of 10-22 m with a resistivity value of around 30.78 Ωm - 314 Ωm. and a deep aquifer at a depth of 40-125 m with a resistivity value of around 22.34 Ωm - 192 Ωm. So drilling is recommended at measurement points SS-1 and SS-3 in deep aquifers because the thicker the soil layer, the more water infiltration.

Abstract

The Petung River supports domestic, agricultural, and economic activities in Pasuruan City but is subject to increasing anthropogenic pressures. This study aims to assess the river water quality status and formulate water pollution control strategies. Water quality was evaluated using the Pollution Index based on laboratory measurements conducted in April and June 2025. A SWOT analysis was performed by identifying internal and external factors through field observations and key informant interviews, followed by weighting and ranking to determine strategic priorities. The results indicate that the Petung River is predominantly classified as lightly polluted, with Pollution Index values ranging from 2.48 to 5.06, while one monitoring point in June 2025 reached a moderate pollution status. Although pH (6.75–7.80) and nitrate (1.15–3.40 mg/L) complied with Class II standards, total suspended solids, biological oxygen demand (6.49–16.01 mg/L), chemical oxygen demand, and total phosphate (0.27–3.03 mg/L) exceeded regulatory thresholds. The priority strategy is the establishment of communal wastewater treatment systems, supported by improved coordination, institutional capacity, community-based programs, and strengthened monitoring.

Abstract

Forest ecosystems play a crucial role in maintaining biodiversity, regulating climate systems, and supporting human well-being. However, widespread deforestation, land-use change, and climate change have caused severe forest degradation worldwide, making forest rehabilitation and biodiversity a global environmental priority. Although the scientific literature linking forest rehabilitation and biodiversity has grown rapidly, a comprehensive understanding of research trends, major contributors, and thematic evolution remains limited. This study presents a global bibliometric analysis of scientific publications on forest rehabilitation and biodiversity from 2000 to 2026 using data retrieved from the Scopus database. A total of 562 peer-reviewed articles were analyzed using the Bibliometrix package in R and the Biblioshiny interface to examine publication trends, authorship patterns, international collaboration networks, influential journals and articles, and thematic structures. The results revealed a steady increase in publication output, with significant acceleration after 2015, coinciding with growing global attention to forest rehabilitation and environmental sustainability issues. Research in this field is highly collaborative, with strong contributions from developed countries, particularly the United States, the United Kingdom, and China. Thematic analysis showed that reforestation, biodiversity, and conservation are the most central and well-developed themes, while climate change, ecosystem services, and land-use dynamics represent emerging areas receiving increasing attention. Overall, this study provides a comprehensive overview of the scientific landscape of research on forest restoration and biodiversity while identifying knowledge gaps and future research directions. These findings offer valuable insights for researchers, policymakers, and practitioners in developing evidence-based strategies for ecological restoration and biodiversity conservation.

Abstract

Liquefaction is one of the dangerous geotechnical phenomena that often occurs due to earthquakes, especially in saturated sandy soils that are not cohesive. Although the area of Langsa City, Aceh is classified as having relatively low seismic activity, the condition of the water-saturated soil still makes it vulnerable to this phenomenon. This study aims to analyze the potential for liquefaction at the Langsa Depot Project site using the Standard Penetration Test (SPT) method. The method used involves correcting the value of N-SPT to N1(60), then the calculation of the Cyclic Stress Ratio (CSR), Cyclic Resistance Ratio (CRR), and Safety Factor (FS) based on the. SPT data was obtained from one drill point with a depth of 50.5 meters and combined with regional seismic data (magnitude 5.1 SR and earthquake acceleration of 0.2 g). The results of the study showed three layers of silty sand that were the focus of the analysis, namely at depths of 6–8 m, 28–35 m, and 48–49 m. The first layer has an FS value of > 1 (1.083 – 1.168) which indicates that this layer does not have the potential for liquefaction, for the second layer has an FS value of > 1 (1.817 – 1.899), so it is declared not to have the potential for liquefaction and is categorized as safe, and the third layer has an FS value of > 1 which is (2.012) is also declared safe from potential liquefaction. These findings confirm the importance of liquefaction evaluation for safe geotechnical design. The study concluded that the project site has two zones that are vulnerable to liquefaction and require mitigation. Keywords: liquefaction, SPT, safety factor, sandy soil

Abstract

Penelitian ini bertujuan untuk mengungkap secara sistematis cara nilai-nilai moral diartikulasikan dalam lirik lagu “Ghibah” karya Rhoma Irama. Kajian nilai moral dan kritik sosial dalam lirik lagu ini dilakukan dengan pendekatan kualitatif deskriptif-analitis. Analisis ini merujuk pada teori sastra, semiotika, perspektif sosial, serta perspektif agama Islam. Pendekatan-pendekatan tersebut digunakan untuk mendalami penggunaan metafora, simbolisme, dan retorika dalam lirik lagu tersebut dapat membentuk pesan moral yang mendalam. Hasil penelitian menunjukkan bahwa lagu “Ghibah” tidak hanya berfungsi sebagai sarana hiburan, tetapi juga sebagai medium yang efektif dalam menyampaikan kritik terhadap praktek mengungkap aib yang sering terjadi dalam masyarakat. Rhoma Irama mengajak pendengar untuk menolak perilaku “Ghibah” dan sekaligus mengarahkan perhatian pada pentingnya introspeksi diri dan kesadaran moral dalam kehidupan sehari-hari. Pesan moral yang terkandung dalam lagu ini mengajak pendengar untuk melakukan refleksi diri, menolak budaya “ghibah”, serta menginternalisasi nilai-nilai keadilan, kejujuran, dan toleransi. Kesimpulannya, lagu “Ghibah” mampu menyampaikan kritik moral secara mendalam melalui penggunaan bahasa yang kaya akan metafora, retorika, dan simbolisme. Penelitian ini diharapkan dapat memberikan kontribusi pada pemahaman lebih luas mengenai keterkaitan antara seni musik, nilai-nilai moral, dan kritikan sosial dalam konteks budaya Indonesia.Kata kunci: Kritik Sosial, Lirik Lagu, Moral

Abstract

The construction of PT. X' depot in Langsa City, Aceh, is located on soft clay soil that requires slope stability analysis for the embankment. This research aims to analyze slope stability using bamboo mattresses and piles as reinforcement to improve the safety factor. The analysis was conducted using manual calculations (Bishop method) and GeoStudio software (also using the Bishop method), under both static conditions and seismic influence (pseudostatic approach with a horizontal seismic coefficient (kh) = 0.18). The manual calculation results showed that the unreinforced slope had a safety factor (SF) of 1.1428 < 1.25 (unstable), which decreased to 0.6711 < 1.1 (unstable) under seismic load. Meanwhile, the GeoStudio software analysis indicated that the unreinforced slope had an SF of 1.256 > 1.25 (stable) but dropped to 0.903 < 1.1 (unstable) under seismic load. The use of 1–4 layers of bamboo piles and matting increased the SF to 1.318–1.35 without seismic influence. Under seismic conditions, the SF of the slope reinforced with 1–4 layers of bamboo piles and matting improved to 0.931–0.97. However, the slope was still considered critical during an earthquake (SF < 1.1).
