Spatio-Temporal Dynamics of Land Use and Land Cover Change and Ecosystem Service Value Assessment in Citarum Watershed, Indonesia: A Multi-Scenario and Multi-Scale Approach Irmadi Nahib, Yudi Wahyudin, Widiatmaka Widiatmaka, Suria Tarigan, Wiwin Ambarwulan, et al. Resources, 2026 Rapid land use and land cover (LULC) changes in densely populated watersheds pose serious challenges to the sustainability of ecosystem services (ES), yet their spatially explicit economic consequences remain insufficiently understood. This study analyzes the spatio-temporal dynamics of LULC and ecosystem service values (ESVs) in the Citarum Watershed, Indonesia, one of the country’s most critical and intensively transformed watersheds. Multi-temporal Landsat imagery from 2003, 2013, and 2023 was classified using a Random Forest algorithm, while future LULC conditions for 2043 were projected using a Multi-layer Perceptron–Markov Chain (MLP–MC) model under three scenarios: Business-as-Usual (BAU), Protecting Paddy Field (PPF), and Protecting Forest Area (PFA). ESVs were quantified at multiple spatial scales (county, 250 m grids, and 100 m grids) using both the Traditional Benefit Transfer (TBT) method and a Spatial Benefit Transfer (SBT) approach that integrates biophysical indicators with socio-economic variables. The contribution of LULC transitions to ESV dynamics was further assessed using the Ecosystem Service Change Intensity (ESCI) index. The results reveal substantial historical forest and shrubland losses, alongside rapid expansion of settlements and dryland agriculture, indicating intensifying anthropogenic pressure on watershed functions. Scenario analysis shows continued degradation under BAU, limited mitigation under PPF, and improved forest retention under PFA; although settlement expansion persists across all scenarios. Total ESV declined from USD 2641.33 million in 2003 to USD 1585.01 million in 2023, representing a cumulative loss of 46.13%. Projections indicate severe ESV losses under BAU and PPF by 2043, while PFA substantially reduces, but does not eliminate economic degradation. ESCI results identify forest and shrubland conversion to settlements and dryland agriculture as the dominant drivers of ESV decline. These findings demonstrate that integrating multi-scenario LULC modeling with spatially explicit ESV assessment provides a more robust basis for ecosystem-based spatial planning and supports sustainable watershed management under increasing development pressure.
Comparison of the accuracy of four satellite rainfall estimates during the rainy season, dry season and transition in South Sulawesi which has complex topography Giarno ., Sayful Amri, Muflihah ., Didiharyono ., Achmad Fahruddin Rais, et al. Mausam, 2026 The sparse distribution of rainfall gauges in Indonesia can be supplemented with satellite products. However, due to the highly dynamic and random nature of rainfall in the region, it is crucial to evaluate the accuracy of these rainfall estimation data. To assess the accuracy of CHIRPS, GCPC, GsMap, and IMERG gridded rainfall data products, numerical comparisons using root mean square error (RMSE) and dichotomous method indicators such as percent correct (PC), false alarm ratio (FAR), bias score (BIAS), probability of false detection (POD), and critical success index (CSI) will be conducted. Analyzing 40 years of data reveals that the accuracy of satellite products is highest in the southern part of South Sulawesi Province, particularly along the west coast. The southern region shows better accuracy than the northern part, and the western area outperforms the eastern region. The accuracy of satellite rainfall estimates varies by location and time, with RMSE values increasing during periods of high rainfall, such as the peak of the rainy season, and decreasing during the dry season. Dichotomous parameters indicate a higher false alarm error compared to missing detections. Among the products, CHIRPS demonstrates the most consistent accuracy, maintaining performance close to the best values. Overall, CHIRPS outperforms the other products, followed by IMERG, GCPC, and GsMap. However, this ranking is subject to change over time and location, necessitating re-evaluation for each application and time period
GLOBAL BLUE CARBON RESEARCH: A BIBLIOMETRIC ANALYSIS WITH A FOCUS ON SMALL ISLAND ECOSYSTEMS (CASE STUDY IN INDONESIA) DELI WAKANO, ISKANDAR Z. SIREGAR, FREDINAN YULIANDA, IRMAN FIRMANSYAH, BONO PRANOTO Journal of Sustainability Science and Management, 2026 This study presents a bibliometric analysis of global blue carbon research, with a specific focus on small island ecosystems in Indonesia. Recognising Indonesia’s significant contribution of approximately 17% to global blue carbon reserves, the analysis explores publication trends, key contributors, and thematic developments in blue carbon science. Notably, a marked increase in research output since 2005, peaking in 2023, underscores the growing recognition of blue carbon’s role in mitigating climate change. This is particularly true in vulnerable coastal ecosystems such as mangroves and seagrasses. Accordingly, the findings reveal an evolution from fundamental carbon storage studies to complex interactions involving anthropogenic impacts and biodiversity considerations. Moreover, this diversification highlights the need for integrated conservation strategies that combine ecological insights with community engagement and policy frameworks. In addition, recommendations for future research include enhancing monitoring methodologies, improving mangrove rehabilitation practices, and increasing community awareness of the benefits of blue carbon. Essentially, by fostering collaborative efforts among scientists, policymakers, and local communities, this analysis contributes to effective conservation policies that optimise the blue carbon potential of Indonesia’s small island ecosystems. This ultimately contributes to global efforts to mitigate climate change.
THE PRODUCTION OF COBALT METAL-IMPREGNATED-ACTIVATED CARBON FROM BAMBOO AS A CATALYST FOR WASTE COOKING OIL (WCO) PYROLYSIS L. Efiyanti, A.I. Cahyani, A. Iryani, D.A. Indrawan, R.S. Ningrum, et al. Rasayan Journal of Chemistry, 2025 Waste cooking oil (WCO) pyrolysis conversion process requires a catalyst to produce high-activity and selectivity products. This research aims to analyze the effect of metal-impregnated activated carbon catalysts in the pyrolysis of WCO. In this study, activated carbon from bamboo was impregnated with Co using carbonization at 450°C for 5 hours, physical activation using steam at 800°C for 75 minutes, and ultrasonic radiation for 60 minutes to form a catalyst. The products obtained were then characterized according to SNI 1683:2021 and 06-3730-1995. Several instrumental analyses, including FTIR, BET, and FESEM-EDS, were also utilized. The catalyst was used to crack waste cooking oil through fast pyrolysis to determine the contents produced. The results showed that the bambooactivated carbon produced met Indonesia's standard. The samples contained several functional groups, including C=O and C=C. The FESEM results show a more developed and open pore morphology when the carbon is treated with steam activation, with an increase in carbon content of up to 91.5%, and the Co metal has been successfully impregnated into the activated carbon of about 2.7%. BET results showed that carbon type I isotherm. In contrast, activated carbon and Co-impregnated catalysts showed a type III isotherm pattern with a micro-mesopore size distribution and a surface area of Co-KABT 3% and Co-KABT 5% catalysts of 368,085 m2 /g and 388,853 m2 /g, respectively. The catalyst's selectivity relatively produced alcohol, hydrocarbons, fatty acids, including aldehydes and ketones. The highest yields of hydrocarbons and alcohol were achieved using a Co-KABT 3% catalyst in the cracking results. The catalyst has demonstrated significant results, increasing the production of alcohol and hydrocarbons by almost 400% and 30%, respectively.
Spatial Analysis of Water Conservation and Its Driving Factors in an Urban Citarum Tropical Watershed: Geospatial Approach Irmadi Nahib, Yudi Wahyudin, Wiwin Ambarwulan, Bono Pranoto, Fadhlullah Ramadhani, et al. Resources, 2025 Water conservation (WC) is a vital ecosystem service (ES) that plays an essential role in the sustainable management of water resources and ensures ecological security. This research examines the WC capacity of the Citarum watershed in West Java Province, Indonesia, from 2010 to 2020. The specific objectives of this research are as follows: (1) to assess the 10-year temporal and spatial variations of WC using the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) and topographic index model; (2) to analyze the temporal interchange between WC and its influencing factors through the Spatial Elastic Coefficient Trajectory Model (SECTM); and (3) to determine the driving factors (DFs) affecting WC by applying Multiscale Geographically Weighted Regression (MGWR). Key findings of this study reveal significant trends in WC from 2010 to 2020: the average WC in the Citarum watershed decreased from 513.96 mm/ha to 453.64 mm/ha (11.74%), indicating a concerning decline in ES capacity. This study also noted that regions implementing comprehensive regulations dominated the study area, covering approximately 72.70% of the total area (502,295 hectares). This illustrates that the implementation of rules plays a crucial role in the WC. Lastly, the MGWR analysis found that WC in the Citarum watershed positively correlated with topography, climate, and vegetation while negatively correlating with socioeconomic factors. This indicates that WC levels are generally lower in areas with higher human activity and economic growth, highlighting the impact of anthropogenic pressures on natural resources. This framework helps stakeholders plan to ensure sustainable development in the area, as it provides valuable insights into the interactions between the ecological and socioeconomic factors affecting WC.
