Abstract

Mount Semeru is an active volcano located on the island of Java. On December 4, 2021, Mount Semeru erupted again, resulting in damage and loss of life. Sentinel-2 satellite imagery was utilized for mapping vegetation areas, while Sentinel-3 was employed for assessing surface temperatures. The NDVI distribution related to the Semeru volcano eruption indicates that the extent of cloud cover, water, and open vegetation was consistent before, during, and after the eruption. Before the eruption, areas of very low vegetation were more prevalent than during and after. In contrast, areas of low vegetation were more common following the eruption compared to the eruption period and before it. Medium vegetation remained dominant after the eruption in comparison to the periods before and during it. In contrast, high vegetation was most abundant during the eruption and was at its lowest before the eruption occurred. The land surface temperature recorded before the eruption ranged from a minimum of 11.8 °C to a maximum of 30.12 °C. During the eruption, temperatures peaked at 42.4 °C and dropped to a low of 14.0 °C. Following the eruption, the maximum temperature recorded was 40.8 °C, with a minimum of 11.6 °C. The presence of lava flow during and after the eruption is indicated by the red circle on the land surface temperature map, and when compared to the NDVI map, the black circle shows areas where vegetation was absent due to the lava flow observed on the land surface temperature map

Abstract

Microtremor analysis was conducted in southern Surabaya, East Java, to evaluate the seismic response of buildings using the Floor Spectral Ratio (FSR) and Random Decrement Method (RDM). Two buildings—a 9-story structure (Building A) and a 10-story structure (Building B)—were analyzed to assess their dynamic behavior and vulnerability to earthquake-induced shaking. As high-rise building development continues in Surabaya, such assessments are critical for enhancing structural safety. The FSR method provided estimates of natural frequency, amplification, and vulnerability index, while the RDM method determined the damping ratio and validated the natural frequency results. The findings show that the average natural frequency of Building A is 1.18 Hz (North-South) and 1.24 Hz (East-West), while Building B has 1.18 Hz and 1.17 Hz, respectively. Damping ratios ranged from 1 to 4% for Building A and 1 to 6% for Building B, both below the 10% critical threshold. The increasing vulnerability index with height indicates greater susceptibility to seismic amplification at upper floors. These findings confirm that both buildings meet the structural standards for multi-story building, reinforcing the importance of dynamic evaluation in earthquake-prone urban areas.

Abstract

This study aims to synthesize and characterize chitosan-tripolyphosphate (CTPP) through ionic crosslinking between chitosan and sodium tripolyphosphate. The CTPP powder was characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and surface area analysis (BET), alongside solubility, swelling, and point of zero charge (pHZPC) tests. FTIR spectra showed a peak at 1151.5 cm⁻¹ attributed to P=O stretching, confirming the interaction between chitosan and tripolyphosphate. XRD analysis indicated shifts in diffraction peaks, suggesting a successful crosslinking reaction. SEM images revealed that the resulting particles had a compact and aggregated morphology. BET analysis showed a decrease in surface area compared to pure chitosan, which may be attributed to particle agglomeration upon crosslinking. Solubility tests revealed that while chitosan is soluble in acidic media, the CTPP product is insoluble. The CTPP showed a swelling percentage of 60% in acidic conditions, indicating its potential responsiveness. The pHZPC measurement indicated a value of 6.2, with ΔpH = 0, suggesting moderate surface charge behavior in neutral pH conditions. Overall, the study confirms the successful synthesis of crosslinked CTPP with distinct physicochemical properties suitable for further application development.

Abstract

This study examines shoreline dynamics in the Banyuasin Estuary, South Sumatra, Indonesia, by integrating multi-decadal satellite imagery (1989-2019) with field-based sedimentation measurements. The research employs Google Earth Engine (GEE) for satellite data processing, FES 2014 tidal corrections to address tidal variations, and the Digital Shoreline Analysis System (DSAS) for precise shoreline change analysis. The primary objective is to comprehensively understand coastline shifts and sediment deposition in stabilising coastal zones. The findings reveal significant shoreline accretion, with net accretion of 2,012 hectares and prominent shoreline advancements at Anakan Island (2,012.33 meters, 118.98 meters/year), while regions such as Sembilang National Park and southern Payung Island exhibited notable erosion (322.71 meters, 10.8 meters/year). The Banyuasin River estuary shifted from notable to extreme accretion phases, contrasting with the more stable shoreline dynamics in the Musi River estuary, where accretion remained stable to intense. The integrated methodology, combining GEE, tidal corrections, and DSAS, offers an innovative approach to monitoring shoreline changes. These findings provide valuable insights for developing sustainable coastal management strategies, particularly in areas facing the dual challenges of climate change and human-induced pressures.

Abstract

This study aims to develop a flipped classroom e-learning model based on Moodle to improve learning outcomes in the Natural and Social Sciences (IPAS) subject for Grade X students at SMK N 1 Praya. The research employed the ADDIE development model, involving stages of analysis (student needs and learning barriers), design (LMS structure, blended strategies), development (digital content, expert validation), implementation (trial in class X Hospitality), and evaluation (formative-summative assessment). The model features pre-class videos, interactive quizzes, e-modules, and online assignments integrated into Moodle. Feasibility was assessed by media, material, and model experts using Likert-scale instruments, scoring 4.0 (feasible) and 4.7 (very feasible). Practicality was evaluated through teacher responses, scoring 4.85 (very practical). Effectiveness was measured via pretest and posttest using the N-Gain formula, showing an average gain of 0.59 (moderate improvement). The model was trialed with 34 students, considering the school's characteristics (vocational focus, limited practice time, and low student engagement). Results indicate that the flipped classroom e-learning model is feasible, practical, and effective in enhancing student outcomes in vocational science learning.
