Abstract

The intensity of the high rainfall resulted in the overflow of the Wae Heru watershed, which resulted in a catastrophic flood that hit residential areas around the watershed. This study aimed to analyze spatially the level of flood hazard and its exposure to settlements in the Wae Heru watershed, Ambon City. This research used overlay technique, scoring method and weighting using ArcMap 10.8 software as a Geographic Information System (GIS) based approach. The variables used included rainfall, elevation, slope, soil type, land cover and distance from the river. The results showed that the flood hazard level was dominated by a low hazard level of 361.28 ha and the flood exposure level in settlements was dominated by a high hazard area of 54.68 ha. The results of the study are expected to be useful in flood mitigation efforts to minimize losses, both fatalities and physical damage.

Abstract

The development of developed land over the last 15 years in Ambon City has affected land cover changes in the Wae Batutangan watershed. This is a result of higher population growth and the need for residential land, which is increasing every year. This study aimed to analyze land cover changes in the Wae Batu Hang watershed in 2012, 2017, and 2022. The method used in this study was a spatial comparison of land cover changes in 2012 and 2017, as well as in 2017 and 2022. Land cover data is obtained from the results of this study. Visual interpretation and digitization where land cover in 2012 was obtained from IKONOS images, and land cover in 2017 and 2022 were obtained from SPOT 6 images. Results of this study showed that the cover of built-up land and open land continues to increase in the area, along with population growth and the high demand for land in watersheds.

Abstract

Perkembangan lahan terbangun di Kota Ambon yang terus meningkat dari tahun ke tahun berpengaruh kepada meningkatnya suhu permukaan daratan yang berdampak pada  sosial-ekonomi dan lingkungan yang merugikan penduduk perkotaan seperti peningkatan penggunaan air, energi yang dikeluarkan untuk pendingin ruangan, serta risiko kesehatan yang disebabkan oleh polusi. Penelitian ini bertujuan untuk mengetahui perubahan suhu permukaan daratan di Kota Ambon tahun 2002, 2012 dan 2022 dengan menggunakan Google Earth Engine berbasis cloud computing. Penelitian ini menggunakan data batas administrasi Kota Ambon dan dataset citra MODIS pada Google Earth Engine, pengolahan data dilakukan berbasis cloud computing. Hasil penelitian menunjukan bahwa di tahun 2002 diperoleh suhu rata-rata Kota Ambon yaitu suhu minimum 21°C dan maximumnya yaitu 30°C, mengalami penigkatan di tahun 2012 menjadi min 24°C dan max 31°C, dan mengalami peningkatan di tahun 2022 menjadi suhu min 23°C dan max 33 °C, disimpulkan bahwa peningkatan suhu permukaan daratan Kota Ambon berbanding lurus dengan peningkatan lahan terbangun yang terjadi dari tahun ke tahunnya.

Abstract

The utilization of geographic information systems (GIS) can make a significant contribution in analyzing the distribution of marine tourism objects in Nusaniwe District. This will help to make better decisions in developing supporting infrastructure, promotion, and improving the quality of services for tourists. This research utilizes Geographic Information System (GIS) technology to map the distribution of marine tourism objects in Nusaniwe District, Ambon City. The results showed that there are eight tourist attractions in Nusaniwe District including; Pintu Kota, Namalatu Beach, Santai Beach, Lima Jari Beach - Dutch Pool, Amahusu Beach, Batu Lubang Beach, Wainitu Beach and Tanjung Nusaniwe. The results of Mapping the distribution of marine tourism objects in Nusaniwe District are expected to help the community in the destination of traveling in Ambon City, especially marine tourism and also useful for the Ambon City government, especially the Tourism Office so that in the future it continues to pay attention and continues to develop marine tourism objects in Ambon City as one of the tourist attractions in Nusaniwe District.
