Abstract

Green open space is at least a minimum requirement for an environmentally sustainable city at 30% of the total area. Pressure on green free space, especially the Green belt area in the river border, tends to increase from year to year due to an increase in urban population. Therefore, this study aims to analyze people's perceptions of the green belt vegetation's role in the watershed of the Wae Batu Gajah watershed in Ambon City. The research method uses descriptive methods that describe a situation based on facts in the field and do not treat the object, with the hypothesis testing procedure using Chi-Square. The results showed that the community's socio-economic parameters consisting of age, formal education, and occupation had a significant influence on the understanding of the green border of the river. In contrast, gender and marital status parameters have no significant effect on understanding the green belt border. Formal education can influence attitudes and behavior through values, character, and understanding of a problem built in stages in a person. The type of work a person has for a long time working will affect the environment's mindset and behavior. The poor only have two sources of income, through salaries / informal business surpluses for basic needs.

Abstract

Penelitian ini bertujuan menganalisis transformasi kandungan air indeks NDWI dan pola spasial pemetaannya di DAS Negeri Rutong Kota Ambon; dan pengaruh atribut lingkungan terhadap pola spasial kandungan air indeks. Metode penelitian menggunakan analisis citra sentinel 2-A dan metode regresi linier berganda, dengan atribut lingkungan seperti temperatur, kelembaban, kerapatan vegetasi dan tipe tutupan lahan. Hasil transformasi kandungan air indeks NDWI dan pola sebaran kandungan air NDWI Negeri Rutong periode 2010-2022 menunjukkan bahwa perubahan persebaran kandungan air NDWI yang mengalami pergeseran pola yang meluas ke wilayah pesisir kearah daratan. Perbedaan antara daerah berair dan daerah kering di sekitarnya terlihat dengan jelas. Kandungan air tinggi mendominasi dengan kandungan air vegetasi pohon mulai mengalami perubahan menurun, sementara kandungan air rendah dan sedang mengalami peningkatan dan menyebar di sepanjang pesisir pantai bergerak menuju ke wilayah daratan. Pola spasial penyebaran kandungan air NDWI rendah dan sedang menyebar dari wilayah pesisir dan daratan menuju perbukitan dan pegunungan. Hasil analisis pengaruh atribut lingkungan terhadap pola spasial kandungan air indeks menunjukkan bahwa parameter temperatur, kelembaban, kerapatan vegetasi dan jenis tutupan vegetasi memiliki pengaruh signifikan secara simultan terhadap kandungan air indeks NDWI pada taraf signifikansi (0.000) lebih kecil dari α 0.05. Hasil Uji parsial (uji-t) menunjukkan bahwa parameter temperatur, kelembaban, dan kerapatan vegetasi memiliki pengaruh signifikan secara parsial terhadap kandungan air indeks NDWI. Sementara variabel jenis tutupan vegetasi memiliki pengaruh tidak signifikan terhadap kandungan air indeks NDWI pada taraf signifikansi α 0.05.

Abstract

Ambon City is the capital of Maluku Province, which is experiencing rapid growth, which can cause environmental degradation and even ecological damage. Therefore, there is a need for sustainable urban forest management as a way to increase green open space. This study aims to analyze urban forest management's technical and social aspects using rationalistic methods through interviews and observations. The assessment results of the three main criteria with assessment indicators show that the understanding of the parties related to urban forests (1168) is included in the high category (1130-1452). The results of the parties' assessment regarding the existence of urban forests based on their function (511) from the score range (368-513) and indicators of forest harmony and balance are in (score 575) from the score range (441 616), each total score is in the medium category. The results of the study technically and socially showed relatively good results. However, urban forest management towards sustainable forest development has yet to be optimally implemented sustainably.

Abstract

This study evaluates the sustainability of Lake Faunil as the principal freshwater source for Tual City, located in a small-island environment characterised by limited groundwater reserves and increasing hydrometeorological vulnerability. Employing a quantitative–descriptive approach, the research analyses ten years of water-quality data—covering BOD, COD, DO, pH, and TDS—alongside seasonal discharge records to examine spatial and temporal dynamics. The results reveal that pH and TDS remain within the Class II water-quality standards established under Government Regulation No. 22/2021, indicating chemical stability and low salinity. In contrast, BOD and COD have consistently exceeded permissible limits since 2018, suggesting chronic organic pollution primarily linked to unmanaged domestic wastewater inflows. Dissolved Oxygen (DO) concentrations during the dry season frequently drop below 4 mg/L, signalling hypoxic stress and early eutrophication processes. Concurrently, discharge data demonstrate a declining trend, with dry-season flows decreasing to as low as 0.036 m³/s, reflecting the system’s strong dependence on rainfall and declining catchment capacity. A subsequent SWOT analysis substantiates these findings by identifying inadequate sanitation systems, riparian degradation, and weak institutional coordination as major internal constraints, while external opportunities include regulatory support, climate and public financing schemes, and the potential role of traditional institutions such as the Saniri Negeri in ecological governance. The study recommends adopting an Integrated Water Resources Management (IWRM) framework that integrates nature-based restoration, community-based sanitation and monitoring, and seasonally adaptive water allocation. Collectively, these strategies provide an evidence-based foundation for policy interventions to enhance freshwater security and resilience within climate-exposed island urban ecosystems.

Abstract

This study evaluates the flood vulnerability conditions of the Wae Batu Merah Watershed (Ambon City) through a socio-hydrology approach that integrates upland ecological dynamics with downstream exposure, sensitivity, and adaptive capacity. A mixed-methods design combined geospatial analysis and household surveys. Landsat-8 imagery (2013–2023) quantified land-cover change and NDVI trends, while BMKG rainfall records (2012–2023) and BPBD flood archives (2013–2022) captured hydrometeorological variability. Peak discharge measurements (2013–2023) characterized flow response. Social data from 178 households included settlement density, poverty, vulnerable age groups, disability, and institutional participation. All indicators were normalized and integrated using Multi-Criteria Evaluation (MCE) in GIS; vulnerability classes were validated through observed flood-point overlays, distinguishing areal distribution from point aggregation. Results show a ~42% loss of upstream vegetation concurrent with a decline in NDVI from 0.46 (2013) to 0.28 (2023), alongside a ~17% increase in peak discharge, evidenced by a strong negative NDVI–runoff correlation. High-to-very-high vulnerability zones cluster along riparian corridors (Batu Merah–Rijali), whereas >90% of the area falls into medium-to-low classes with fewer flood points. Social vulnerability co-occurs with high density, poverty, limited risk awareness, and weak institutional engagement. The socio-hydrology–MCE framework offers a replicable basis for adaptive risk governance, prioritizing riparian setbacks, vegetation rehabilitation, density management, and capacity-building under increasing climatic pressure.

Abstract

Daerah Aliran Sungai (DAS) Wae Halong di Pulau Ambon merupakan salah satu wilayah yang mengalami perkembangan pesat yang ditandai dengan konversi lahan secara masif untuk permukiman. DAS dengan luas ±458 ha ini memegang peran krusial dalam menjaga keseimbangan hodrologis dan ekologis bagi masyarakat sekitarnya. Penelitian ini bertujuan untuk menganalisis secara komprehensif perubahan tutupan lahan dan perubahan struktur ekologi lanskap DAS Wae Halong selama periode 1996 hingga 2024. Metode yang digunakan adalah pendekatan campuran (mixed methods), yang memadukan analisis spasial kuantitaif dengan data kualitatif dari survei lapangan. Fokus utama analisis adalah perubahan data tutupan lahan multitemporal berbasis Informasi Geografis (SIG), dan perhitungan matrik lanskap menggunakan perangkat lunak Fragstat. Hasil analisis menunjukan adanya tren fragmentasi lanskap yang siginifikan. Tutupan lahan alami khususnya hutan dan semak belukar mengalami penurunan luas drastic yang diperkirakan mencapai 50% dalam kurun waktu 28 Tahun. Sebaliknya, lahan terbangun meningkat tajam terutama didorong oleh pembangunan perumahan besar yang intens setelah tahun 2011. Pergeseran dominansi lanskap dari tutupan lahan alami ke permukiman secara langsung mengindikasikan penurunan daya dukung lingkungan, hilangnya koridor ekologis, dan peningkatan kerentanan DAS terhadap bencana seperti banjir dan tanah longsor.

Abstract

Land cover change is an urgent global issue that needs to be addressed immediately. Its dynamics are of the greatest importance to Key Biodiversity Areas (KBAs) along the Wallacea Corridor, including Buano Island, whose land and sea are rich in biodiversity. KBA Buano Island is home to endemic and endangered birds, such as Moluccan scrubfowl (Eulipoa wallacei) and black-chinned monarch (Monarcha boanensis). Black-chinned monarch only lives on the island (single-site species). Buano waters have an interestingly diverse life, including dugong (Dugong dugon), hawksbill turtle (Eretmochelys imbricata), loggerhead turtle (Caretta caretta), and many species belonging to the dolphin family (Delphinidae) and beaked whale family (Ziphiidae). This study was designed to analyze and map the spatial-temporal patterns of land cover changes on Buano Island. It employed a multi-temporal analysis on Landsat images from 1970, 1980, 1990, 2000, 2010, until now, and a t-test to analyze the results further. The t-test analysis produced t-count ≥ t-table at confidence level (α) of 0.05, indicating significant changes in land cover from 1970, 1980, 1990, 2000, 2010, until 2016. These multitemporal-spatial dynamics were attributable to fluctuation in population growth and open and straightforward access between the island and the capital of the regency. Furthermore, from the aspect of fishery and maritime affairs, Buano Island already had synergistic land area development.

Abstract

Hydrological phenomena on the scale of a watershed are complex and may never be understood holistically. One of the innovations in baseflow hydrological modelling is the analysis of the baseflow recession curve, generally expressed as the natural storage of river flows and containing valuable information about the properties and characteristics of natural aquifer storage. This study aims to model land use change and baseflow recession in the Wuryantoro watershed, Wonogiri Regency, Central Java Province. The research method uses an exponential model in which changes in the characteristics of a baseflow recession are a function of land use changes over a certain period. The calibration of the seven graphical models of land use change against the characteristics of the baseflow recession shows that the seven curves of the land use change graphic model have model coefficients and curve slopes that vary from gentle to steep. The slope of the gentle and steep curve describes the bottom flow deposits' condition over time. The state of water storage in the seven better graphical models is that the change of forest remains forest followed by the change of agriculture into the forest, forest into the settlement, change of agricultural land into the settlement, change of forest to agricultural land, settlement remains settlement and change of agricultural land remains agrarian land.
