Abstract

Coastal zones are dynamic transitional environments subject to continuous morphological change driven by fluvial, marine, and anthropogenic processes. This study investigates the temporal dynamics of delta growth and shoreline change at the Blorong River estuary, Kendal, Central Java, Indonesia, over 52 years (1972 to 2024) using multi-temporal remote sensing analysis based on Landsat imagery series 1 to 8 processed in ArcGIS. The results show a total delta accretion of 2.5852 km² with an average rate of 0.0549 km²/year. The accretion occurred in four distinct phases, namely 0.0714 km²/year during 1972 to 1988, 0.0952 km²/year during 1988 to 1999, 0.0393 km²/year during 1999 to 2009, and 0.0138 km²/year during 2009 to 2024. The progressively declining growth rate suggests a reduction in delta progradation intensity over time, reflecting the combined influence of decreasing upstream sediment supply, dam construction, land-use change, groundwater extraction-induced subsidence, and sea-level rise. These findings highlight the need for integrated coastal zone management through watershed-scale sediment budgeting, mangrove-based coastal protection, and periodic remote sensing monitoring. Future research should incorporate sediment flux measurements, InSAR-based subsidence analysis, and hydrodynamic modeling to improve the understanding of delta evolution and vulnerability under changing climate conditions.

Abstract

“Penelitian ini dilatarbelakangi oleh pentingnya kinerja guru PAUD sebagai faktor penentu kualitas pembelajaran, yang dipengaruhi oleh berbagai aspek termasuk tingkat pendidikan dan masa kerja. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei. Data dikumpulkan melalui angket berskala Likert (1–4) yang mengukur indikator perencanaan, pelaksanaan, dan evaluasi pembelajaran. Sampel penelitian berjumlah 51 guru TK di Kecamatan Cakranegara, dipilih menggunakan rumus Slovin. Analisis data meliputi uji validitas, reliabilitas, uji asumsi klasik, serta uji parsial (t). Hasil penelitian menunjukkan bahwa baik tingkat pendidikan maupun masa kerja tidak berpengaruh signifikan terhadap kinerja guru (Sig. X1 = 0,785; Sig. X2 = 0,628).” Secara deskriptif, variasi antar kategori pendidikan dan masa kerja tetap ada, namun tidak menghasilkan perbedaan yang bermakna. Penelitian ini menyimpulkan bahwa kinerja guru lebih dipengaruhi faktor lain seperti pelatihan, pengalaman mengajar, motivasi, supervisi, dan lingkungan kerja, sehingga peningkatan kualitas guru perlu diarahkan pada pengembangan profesional berkelanjutan.

Abstract

The increasing demand for clean water in Selebar Subdistrict, Sumur Dewa Village, Bengkulu City has prompted research to identify and map aquifer zones more accurately. This study aims to analyze the presence and depth of aquifers using the Vertical Electrical Sounding (VES) geophysical method, which is then verified using borehole lithological data. VES data collection was conducted at three sounding points (n=3) using a Schlumberger configuration with an AB/2 electrode spacing of 250 m. The acquired geophysical data were processed using IPI2win software with an error value (RMS error) >5%, resulting in a one-dimensional (1D) subsurface model that was further developed into a two-dimensional (2D) cross-section. The results indicate that the main aquifer zone is located at a depth of 51–75 meters, characterized by low resistivity values (<50 Ωm), indicating a water-saturated layer identified as the groundwater zone. This is consistent with drilling data, which show indications of water loss at the same depth interval, thereby reinforcing the assumption of groundwater presence in that aquifer layer. Based on these results, it can be concluded that the integration of the VES geoelectric method, verified with borehole cross-section data, is effective in characterizing subsurface structures and mapping aquifer zones more accurately.

Abstract

Indonesia holds the world's largest nickel resource potential, with significant reserves in Southeast Sulawesi dominated by lateritic deposits derived from ultramafic rock weathering. The research area is in Wolo District, Kolaka Regency, with prominent Ni prospect. This study evaluates the influence of slope gradient and bedrock lithology on Ni grade distribution within lateritic profiles. Methods included literature review, bedrock and core sampling, petrographic and XRF analyses, and ArcGIS–Surfer–Excel processing for spatial and boxplot-based correlation analysis. Results show that in Pit A, characterized by relatively flat morphology, the highest Ni grades (average 1.2%) occur in saprolite on gentle slopes (2–7°), where optimal infiltration and intensive peridotite weathering favor downward Ni enrichment, while limonite enrichment develops on moderate slopes (15–30°) over dunite. In contrast, Pit B, with steeper hill–mountain morphology, records peak Ni grades (average 1.4%) in limonite on steep slopes (30–70°), where dunite weathering combined with limited deep infiltration and leaching leads to preferential Ni retention in the limonite zone, and peridotite generally yields lower grades due to morphology-related less efficient Ni trapping.

Abstract

West Lampung Regency is located within an active tectonic zone associated with the Sumatra Fault system and is therefore vulnerable to significant earthquake ground shaking. This study aims to identify the spatial distribution of Peak Ground Acceleration (PGA) based on local site characteristics derived from microtremor measurements. Microtremor data were recorded at distributed observation points and analyzed using the HVSR method to determine the dominant frequency (f₀) and amplification factor (A₀) of the soil. The results indicate that f₀ values range from 0.544 to 15.1 Hz, while A₀ values vary between 1.66 and 8.57, reflecting heterogeneous subsurface conditions. These parameters were used to estimate PGA, which ranges from 0.105 to 0.565 g across the study area. Higher PGA values are generally associated with areas characterized by lower dominant frequencies and higher amplification, indicating thicker or softer sediment layers. The resulting PGA distribution map reveals zones with relatively higher seismic response potential. These findings demonstrate the importance of site-specific dynamic characterization in seismic hazard assessment and provide essential information for earthquake risk mitigation and regional development planning in West Lampung Regency.

Abstract

The utilization of mahogany sawdust waste as an additive in concrete blocks production serves as an effort to reduce environmental pollution while providing a more eco-friendly alternative building material. This study aims to analyze the effect of adding mahogany sawdust on the compressive strength of concrete blocks and to assess their conformity with the quality standards of SNI 03-0349-1989. The research was conducted experimentally using sawdust variations of 0%, 1%, 3%, and 5% of the fine aggregate weight, with cube specimens measuring 15 × 15 × 15 cm tested at 28 days. The results show that the addition of sawdust decreases both the weight and compressive strength of the blocks, where the normal block reached a compressive strength of 10.92 MPa, which then dropped to 4.88 MPa at 1%, 3.29 MPa at 3%, and 1.56 MPa at 5% variation. This reduction is caused by the porous and lightweight characteristics of sawdust, along with its high water absorption, which inhibits cement hydration and reduces the density of the block structure. Based on SNI standards, none of the variations met Quality Grade I, however, the 1% and 3% mixtures still fall within Quality Grades III and IV. Overall, mahogany sawdust can be utilized as an environmentally friendly additive for non-structural concrete block applications, but it is not recommended for uses requiring high compressive strength.

Abstract

This study aims to analyze the improvement of students’ conceptual understanding of energy and wave functions in a three-dimensional particle-in-a-box system through the use of a web-based Schrödinger 3D simulation. This research employed a quantitative approach with a one-group pretest–posttest design involving 20 physics students. The instrument used was a conceptual understanding test administered in the form of pretest and posttest. Data were analyzed using descriptive quantitative analysis and the Normalized Gain calculation. The results showed a significant improvement in students’ understanding. The average pretest score of 5.9 (39.3%) increased to 14 (93.3%) in the posttest. The N-Gain value of 0.89 was categorized as high, indicating that the web-based simulation is highly effective in enhancing students’ conceptual understanding. Based on questionnaire responses, the simulation was found to effectively visualize abstract concepts, increase learning engagement, and facilitate understanding of the relationship between energy, wave functions, and quantum numbers. However, several limitations were identified, particularly in the deeper understanding of wave functions and the need for further feature development. Therefore, the use of a web-based Schrödinger 3D simulation can serve as an effective alternative learning medium to improve students’ conceptual understanding in abstract quantum mechanics topics.

Abstract

Climate change has become one of the major challenges in the development of the agricultural sector in Indonesia, as it directly affects productivity, production stability, and farmers’ welfare. The increasing frequency of extreme events such as droughts, floods, and shifting rainfall patterns has led to higher risks of crop failure and ecosystem degradation. Therefore, sustainable adaptation strategies are required to enhance the resilience of the agricultural sector while supporting long-term development. This article aims to analyze various sustainable adaptation strategies in Indonesia’s agricultural sector, including community-based approaches, the application of climate-smart agriculture technologies, income diversification, as well as financial and policy support. Furthermore, this study links these strategies to the achievement of the 17 Sustainable Development Goals (SDGs), particularly in areas such as food security, poverty alleviation, climate action, ecosystem protection, and global partnerships. The findings indicate that the integration of comprehensive and collaborative adaptation strategies can improve farmers’ resilience to climate change, strengthen national food security, and significantly contribute to the overall achievement of the SDGs. Therefore, synergy among the government, private sector, and communities is essential to establish a resilient and sustainable agricultural system in Indonesia.

Abstract

This study examines the grain-size distribution of the Tutut Formation sandstone using granulometric analysis. The purpose of this granulometric observation is to determine the depositional environment and its transportation mechanisms. In addition to using granulometric methods, this study also includes geological mapping to observe the rock lithology in the field. The results show that the study location consists of sandstone and mudstone units of the Tutut Formation, Meulaboh sand deposit units, and alluvial deposit units. The characteristics of Tutut Formation sandstone are gray-brown, reddish-brown due to weathering, coarse to fine sand grain size, medium to slightly rounded roundness, and does not react with HCl. Based on granulometric analysis, Tutut Formation sandstone has an average grain size of 0.214-0.327 ϕ, which is classified as coarse sand. The degree of sorting is 0.321 ϕ to 0.417 ϕ, with an average of 0.35 ϕ, so it is classified as good. Skewness values range from 0.107 to 0.263, with an average of 0.1775 ϕ, indicating fine skewness. The 0.1775 ϕ of the average skewness value indicates that the flow in this depositional environment is turbulent and a river depositional environment. Meanwhile, the kurtosis value ranges from 0.060 to 0.11, indicating a platykurtic to highly platykurtic distribution, suggesting a fairly diverse and even grain-size distribution from fine sizes in the matrix to coarse sizes. The diverse grain size implies that the matrix fills the pores between coarse grains. Thus, porosity is not available and has no potential as a reservoir rock.

Abstract

This study focuses on Seram Bagian Timur, an area known for its complex geological setting and active tectonic. Recent seismic events, including the 26 September 2019 Ambon earthquake (Mw 6.5) and the 22 June 2025 earthquake near Bula (Mw 5.0), indicate the presence of active fault systems and heterogeneous subsurface conditions. These conditions govern how seismic waves are modified at the ground surface particularly variation in subsurface material properties. This effect is represented by the amplification factor, which estimated using the empirical relationship proposed by Fujimoto and Midorikawa. The objective of this study is to examine the spatial variability of site response using Vs30 data from USGS, along with amplification factors and dominant periods. The analysis is based on 6,550 grid points with a spatial resolution of approximately 930 m, supported by regional geological information. Data processing involved extraction, interpolation, and mapping, while amplification and dominant period were estimated using empirical approach The results indicate that Vs30 values range from 180 to 900 m/s (site classes BC–E), with lower values concentrated in coastal and eastern areas, and higher values predominantly found in the western part of the study area. Amplification factors vary between 0.77 and 2.79, generally falling within low to moderate categories. Meanwhile, dominant periods range from 0.133 to 0.667 seconds, representing soil types from hard to very soft conditions. Overall, the three parameters show a consistent pattern, where lower Vs30 values tend to correspond to higher amplification and longer dominant periods, reflecting less consolidated subsurface materials.
