PEMETAAN KONFLIK MANUSIA DENGAN BIAWAK (Varanus salvator) BERBASIS WEB SCRAPING BERITA ONLINE

Latar Belakang: Laju pertumbuhan penduduk bumi yang sangat tinggi dalam beberapa dekade terakhir berimbas terhadap meningkatnya luasan lahan pertanian secara pesat. Salah satu akibat yang muncul dari laju perubahan lahan hutan adalah semakin banyaknya konflik yang muncul antara satwa liar dengan manusia. Meskipun konflik manusia dengan satwa liar juga banyak ditemukan di Indonesia, namun usaha untuk melakukan inventarisasi dan pemantauan jenis-jenis konflik beserta sebarannya masih terbatas. Mamalia dan burung merupakan dua kelompok satwa liar yang telah dikaji secara luas.Metode: Penelitian ini berusaha mengumpulkan data kejadian konflik manusia dengan biawak yang sering muncul di berita-berita daring. Pengumpulan berita dari media online (web scraping) dilakukan secara otomatis dengan menggunakan python package GoogleNews. Berita yang terkumpul dan disimpan dalam format spreadsheet diolah untuk mendapatkan informasi lokasi dan jenis konfliknya.Hasil: 35 kasus konflik biawak pada tahun 2019 dan 66 kasus pada tahun 2020 berhasil dipetakan dan diketahui jenis-jenisnya. Kasus kemunculan biawak di wilayah pemukiman/perkantoran merupakan kasus yang paling banyak diberitakan dimana wilayah Jabodetabek mendominasi pemberitaan konflik manusia dengan biawak.Kesimpulan: Penelitian ini menunjukkan teknik web scraping sangat berguna untuk mengumpulkan berita tentang konflik manusia dengan biawak dalam waktu yang cepat. Berita yang dikumpulkan dapat menunjukkan persebaran dan jenis konflik biawak di Indonesi

Where did Venomous Snakes Strike? A Spatial Statistical Analysis of Snakebite Cases in Bondowoso Regency, Indonesia

Snakebite envenomation in Indonesia is a health burden that receives no attention from stakeholders. The high mortality and morbidity rate caused by snakebite in Indonesia is estimated from regional reports. The true burden of this issue in Indonesia needs to be revealed even starting from a small part of the country. Medical records from a Hospital in Bondowoso Regency were the data source of the snakebite cases. Three spatial statistical summaries were applied to analyze the spatial pattern of snakebite incidents. The comparison between statistical functions and the theoretical model of random distributions shows a significant clustering pattern of the events. The pattern indicates that five subdistricts in Bondowoso have a substantial number of snakebite cases more than other regions. This finding shows the potential application of spatial statistics for the snakebite combating strategy in this area by identifying the priority locations of the snakebite cases

Modelling and dynamic water analysis for the ecosystem service in the Central Citarum watershed, Indonesia

Exploring the drivers of changes in ecosystem services is crucial to maintain ecosystem functionality, especially in the diverse Central Citarum watershed. This study utilises the integrated valuation of ecosystem service and trade-offs (InVEST) model and multiscale geographically weighted regression (MGWR) model to examine ecosystem services patterns from 2006 to 2018. The InVEST is a hydrological model to calculate water availability and evaluate benefits provided by nature through simulating alterations in the amount of water yields driven by land use/cover changes. Economic, topographic, climate, and vegetation factors are considered, with an emphasis on their essential components. The presence of a geographical link between dependent and explanatory variables was investigated using a multiscale geographic weighted regression model. The MGWR model is employed to analyse spatial impacts. The integration of both models simplified the process and enhanced its understanding. The findings reveal the following patterns: 1) decreasing land cover and increasing ecosystem services demand in the watershed, along with a decline in water yield, e.g. certain sub-districts encounter water scarcity, while others have abundant water resources; 2) the impact of natural factors on water yield shifts along vegetation > climate > topography (2006) changes to climate > vegetation > topography (2018)

Spatial-Temporal Changes in Water Supply and Demand in the Citarum Watershed, West Java, Indonesia Using a Geospatial Approach

Balancing water supply demand is vital for sustaining livelihoods. Spatial mapping and calculating water yield dynamics due to land use changes over decades are needed to manage land resources and formulate ecological protection policies. This study mapped the supply, demand, and matching status of water product service using the Integrated Valuation of Ecosystem Service and Tradeoff (InVEST) biophysical models in the Citarum Watershed (CW) in 2000, 2010, and 2020. Moreover, this study used Exploratory Spatial Data Analysis (ESDA) and Geographic Information System (GIS) techniques to study the agglomeration characteristics and evolutionary trajectories of supply–demand over two decades. The results showed that between 2000–2010 and 2010–2020, the water supply decreased by 19.01 × 108 m3 (18.28%) and 12.97 × 108 m3 (15.27%), respectively. However, the water demand in the same period increased by 6.17 × 108 m3 (23%) and 15.74 × 108 m3 (47%), respectively. Over the decades, the contribution of land use land cover (LULC) changes to variations in water supply has yielded values ranging from 2.87% to 6.37%. The analysis of the water supply–demand imbalance indicated that the entire CW experienced water shortage, and the type of spatial matching for supply and demand is dominated by a high supply and high demand class (16.09% of the total area). Based on the level of water deficit calculation, the upstream and downstream areas were identified as zones that require ecological conservation, while the middle CW area requires ecological restoration or ecological improvement
