Analysis of the impact of land use changes on hydrological responses in the Cisadane watershed, Indonesia Iwan Ridwansyah, Hidayat Pawitan, Yayat Hidayat, Meti Yulianti, Andi Muhammad Yasser Hakim International Journal of Environmental Studies, 2026 The Cisadane watershed, a densely populated region undergoing rapid land use changes, may alter hydrological characteristics such as water yield, surface runoff, and baseflow. This study assesses how these changes impact flood occurrences using the SWAT hydrological model and CLUE-S model. Land use changes from 2010 to 2030 were projected in 20-year intervals. Calibration and validation of the CLUE-S model showed high accuracy (73% overall accuracy, Kappa coefficient 66%). SWAT model validation indicated satisfactory results (R2: 0.65, NSE: 0.56). According to CLUE-S, urban expansion will notably increase, reducing forest and agricultural areas. SWAT simulations predict an increase in maximum daily discharge: from 735 m3/s in 1990 to 775 m3/s in 2010, with a projection of 779 m3/s in 2030. Controlling land use changes in forests, agriculture, and water bodies could effectively mitigate flood risks, with simulations revealing a maximum-minimum discharge ratio of 49, indicating significant daily water flow variability.
Impact of Land Use Change on Hydrological Responses in the Jongkok-Meninring-Babar (JMB) Watershed, Lombok Island, Indonesia Iwan Ridwansyah, Hendro Wibowo, Endra Triwisesa, Andi Muhammad Yasser Hakim, Aan Dianto Bio Web of Conferences, 2025 Lombok Island, covering 4,672 km 2 with a population of about three million, is a popular tourist destination yet highly vulnerable to environmental degradation driven by rapid tourism and settlement expansion. This study investigates the impact of land use change on hydrological response using the SWAT model. Land use dynamics were analyzed through satellite image classification, revealing that most urban growth in Mataram City has replaced paddy fields, while in upstream areas it has encroached on plantations and agricultural land. Model calibration and validation achieved Nash-Sutcliffe Efficiency (NSE) values of 0.66 and 0.55, respectively, indicating acceptable performance. The simulation results from 1995 to 2017 show significant hydrological alterations: surface runoff increased by 33.1 mm/year, while base flow and deep aquifer recharge declined by 12.3 mm/year and 12.5 mm/year, respectively. These findings highlight the adverse effects of urban expansion on the island's water resources, emphasizing the need for sustainable land use planning to balance development and environmental protection.
The Wallacea Wetland Research Collaboration Center: A Nexus for Ecosystem Data, Biodiversity Insights, and Management Strategies Triyanto, Latifa Fekri, Asriyana, Gadis Sri Haryani, La Ode Muhammad Yasir Haya, Tri Widiyanto, Sjamsu Alam Lawelle, Lukman, Romy Ketjulan, Cynthia Henny, Irdam Riani, Sekar Larashati, Muhammad Idris, Nofdianto, Andi Muhammad Yasser Hakim, Djamhuriyah S. Said, Hasan Eldin Adimu, Octavianto Samir Bio Web of Conferences, 2025 The Wallacea Wetland Research Collaboration Center was founded in 2024 through BRIN's Research Collaboration Center Program, in partnership with Halu Oleo University and BRIN's Research Center for Limnology and Water Resources. It focuses on wetland ecosystems in Wallacea—covering Sulawesi, Nusa Tenggara, and Maluku—regions rich in biodiversity and endemism but still underexplored. The center integrates ecosystem data, assesses biodiversity, and develops inclusive wetland management strategies. Through interdisciplinary collaboration, it promotes ecological data collection, biodiversity synthesis, and adaptive frameworks that blend global conservation principles with local wisdom. Addressing challenges like habitat degradation, climate resilience, and fair resource governance, the center emphasizes wetlands as vital yet often overlooked ecosystems. Rooted in scientific diplomacy, social justice, and community empowerment, it fosters knowledge exchange, policy dialogue, and capacity building among academic and local stakeholders. Ultimately, it envisions wetlands as both ecological treasures and socio-cultural landscapes where biodiversity and community livelihoods thrive together.
Defining Urban Growth Boundary in Semarang City: Integrating Spatial Planning and Predictive Modeling Techniques A M Y Hakim, B H Santosa, R Purwana Iop Conference Series Earth and Environmental Science, 2025 Understanding the maximum percentage of urban area within an administrative region, such as Semarang City, necessitates an examination of spatial planning schemes, development regulations, and local government policies. Concurrently, cellular automata and Markov chain approaches can be used to predict how cities will grow in the future accurately. This study aims to define the urban growth boundary in Semarang City by integrating spatial planning approaches with predictive modeling techniques. The Cellular automata-Markov chain (CA-MC) method predicts future urban growth developments based on current land use patterns. This study seeks to delineate areas suitable for urban development using spatial data analysis and modeling while preserving critical ecological and agricultural zones. The findings of this research contribute to formulating informed policies aimed at achieving balanced urban expansion and environmental conservation in Semarang, thus fostering resilient and inclusive urban landscapes in the city.
Correlation between population growth and land use change: a study in the catchment area of Singkarak Lake, West Sumatra A M Y Hakim, I Ridwansyah, D B Sencaki Iop Conference Series Earth and Environmental Science, 2024 Many studies state that one of the anthropogenic impacts that directly affects the environment is population growth. Population growth is an undeniable and inevitable global phenomenon. It has significant implications for various aspects of human civilization and the environment, one of which is land use patterns. The relentless growth of the world’s population puts enormous pressure on the utilization and distribution of land resources. Along with demographic shifts in rural areas and accelerated urbanization, land use patterns undergo substantial transformation. Therefore, this study aims to measure the correlation between population growth and land use change using the Pearson correlation method. Data on the number of inhabitants was obtained from the Central Bureau of Statistics; meanwhile, the land use maps were obtained from the classification of Landsat 8 OLI satellite images that were processed in Google Earth Engine. The research location was carried out in the Catchment Area of Singkarak Lake, West Sumatra with a range of data use from 2013 to 2022 (10 years). The outcome indicated a Pearson correlation coefficient of 0.979. This study ultimately reinforces the assertion regarding the strong correlation between population growth and land use change, particularly in the context of urban expansion.
Assessment of future environmental carrying capacity in the Mamminasata area, Indonesia, derived from regional census and land cover Andi Muhammad Yasser Hakim, Sumbangan Baja, Dorothea Agnes Rampisela, Samsu Arif, Masayuki Matsuoka, Iwan Ridwansyah International Journal of Environmental Studies, 2023 Environmental carrying capacity is central to the sustainable development concept that has been applied in spatial planning programs by the Government of Indonesia. These programs focus on population needs based on existing conditions and projected population growth. This study predicted the future environmental carrying capacity of the region called Mamminasata (Makassar City, Maros, Sungguminasa and Takalar Regencies) to 2031 through statistical calculation. Census data from local government agencies and land cover prediction data from previous studies were used. The respective results for demographic, residential, and protected function carrying capacities by 2031 were 0.104 (good), 6.297 (good), and 0.520 (good but requiring attention to prevent further decline). Projected agricultural carrying capacity in 2031 would leave about 45% of the agricultural land now used for food crops. The results of this research can assist sustainable development in Mamminasata.
Quantifying future environmental carrying capacity based on land use/land cover data and ecosystem services valuation: a case study in Makassar City, Indonesia Andi Muhammad Yasser Hakim, Sumbangan Baja, Dorothea Agnes Rampisela, Samsu Arif International Journal of Environmental Studies, 2022 Several studies have focused on present environmental carrying capacity, but predictions based on future conditions are rarely considered. In this study, land use/land cover (LU/LC) data and ecosystem services valuation (ESV) were used to quantify the future environmental carrying capacity in Makassar City by 2031. The LU/LC data were based on previous research and the ESV coefficients were based on Muta’ali (2015). The results predict that all types of ecosystem services in Makassar City will decrease every year and will be below 0.5 of current values by 2031. These results can be used to inform plans for sustainable development in Makassar City.
