Abstract

Kebutuhan air di bumi dimanfaatkan untuk berbagai macam sektor. Salah satu bentuk pemanfaatannya adalah untuk memenuhi kebutuhan air bersih dan air minum bagi manusia. Jenis kebutuhan air dapat berupa kebutuhan air domestik atau kebutuhan air rumah tangga, kebutuhan non domestik, pelayanan umum dan industri. Kebutuhan air bersih untuk masing-masing daerah tentunya berbeda-beda. Kebutuhan akan penyediaan dan pelayanan air bersih dari waktu ke waktu semakin meningkat yang terkadang tidak diimbangi oleh kemampuan pelayanan. Peningkatan kebutuhan ini disebabkan oleh peningkatan jumlah penduduk, peningkatan derajat kehidupan warga, serta perkembangan kota/kawasan pelayanan ataupun hal-hal yang berhubungan dengan peningkatan kondisi sosial ekonomi warga yang dibarengi dengan peningkatan jumlah kebutuhan air per kapita. Kota Tiakur, Kecamatan Moa Kabupaten Maluku Barat Daya (MBD) Provinsi Maluku merupakan wilayah yang berada di Pusat Ibu kota Kabupaten Maluku Barat Daya, di dalam Kota Tiakur terdapat Kelurahan Tiakur dan Desa Wakarleli. Luas wilayah Kota Tiakur 2351Ha dengan jumlah jiwa 8701 jiwa pada tahun 2023 (BPS Kab. MBD). Untuk memenuhi kebutuhan air bersih di Kota Tiakur, masyarakat mengunakan layanan PERUMDAM Tirta Kalwedo. Sumber air baku yang digunakan PERUMDAM Tirta Kalwedo untuk melayani SPAM Kota Tiakur adalah mata air sumur bor El-wonna dengan kapasitas debit 25 liter/detik dan sumur bor deepwell dengan kapasitas debit 5 liter/detik. Berdasarkan hasil Analisa Kebutuhan penduduk samapai tahun 2033 adalah sebesar 20,74 liter/detik. Sedangkan, Berdasarkan hasil Perbandingan Air (water balance) diketahui bahwa ketersedian air pada sumur bor Ell wona dan sumur bor Deep well yang menjadi sumber air baku dari PERUMDAM Tirta Kalwedo masih mampu untuk memenuhi kebutuhan air bersih sampai pada tahun 2033.

Abstract

South Leitimur District is one of the coastal areas in Ambon City, with a landscape consisting of mountains, hills, and a fairly long coastline. The coastal area in South Leitimur District has experienced coastal damage, such as abrasion, damage to coastal protection structures, and a decline in the quality of the coastal environment. One real-life case that has been highlighted is the damage to the embankment in Hutumuri Village due to prolonged abrasion and increasing sea wave intensity. This study aims to assess the level of coastal damage that has occurred in South Leitimur District and determine the priority scale for its handling based on the severity of the damage and the level of regional importance. The method used refers to the guidelines of the Circular Letter of the Minister of Public Works No. 08/SE/M/2010. The assessment was conducted in five villages: Hutumuri, Rutong, Leahari, Hukurila, and Kilang. Each coastal segment was analyzed using the EA-2 benchmark (damage to coastal structures), taking into account visual aspects in the field, photo documentation, and GPS coordinates. The results showed that most coastal segments experienced levels of damage ranging from light to very severe. The segments with the highest damage were segments 4b and 7b in Hutumuri Village, and Segment 1b in Kilang Village, with a damage score of 200, which falls into the priority category C (Preferred). This situation indicates an urgent need for coastal protection measures and rehabilitation. Furthermore, the weighting calculation also takes into account the importance of the area, such as the presence of dense settlements, main road access, and economic activity in the surrounding community.

Abstract

Coastal areas are currently facing serious threats due to changes in the coastline caused by natural factors such as waves, tides, and ocean currents, as well as human activities such as reclamation, coastal development, and mangrove deforestation. Changes in the coastline can have a direct impact on coastal ecosystems and the lives of surrounding communities, especially in areas where economic activity depends on coastal resources. One area experiencing such dynamics is the West Leihitu District in Central Maluku Regency. This study aims to analyze coastline changes in the West Leihitu District during the period 2015 to 2024 using Landsat 9 satellite imagery and the Geographic Information System (GIS)-based Digital Shoreline Analysis System (DSAS) method. The analysis was conducted spatially and temporally to determine the extent of shoreline shifts, both forward and backward. The image data were processed through radiometric and geometric correction, land-sea boundary delineation, shoreline digitization, and inter-year overlay. The Net Shoreline Movement (NSM) and End Point Rate (EPR) methods were used to calculate the distance and rate of shoreline change. The results of the study show that there were varying changes in the coastline in five coastal villages, namely Larike, Wakasihu, Allang, Liliboy, and Hatu. Larike Village experienced the greatest coastline advance with an average change of 7.05 meters and a rate of 0.78 meters/year, followed by Wakasihu Village with an average of 6.69 meters and a rate of 0.74 meters/year. Meanwhile, Allang and Liliboy villages showed a tendency for shoreline retreat, with average changes of 4.25 meters and 0.85 meters, respectively. Hatu village experienced relatively small changes and tended to be stable.

Abstract

Negeri Passo Benteng Karang, a hamlet in Baguala Sub-district, is located in a hilly area with rocky soil, making it challenging to access groundwater sources. Despite having one borehole and a single reservoir, the community frequently faces clean water shortages, as the current supply is insufficient for daily needs. To address this issue, a cost-effective and efficient solution, namely rooftop rainwater harvesting (RWH), is proposed. This study analyzes climate, rainfall using the Gumbel method, community water demand, planned discharge using the rational method, and the potential of RWH. The results indicate a maximum harvestable water volume of 4,133.5 m³/day with rainfall exceeding 100 mm, while the clean water demand is 144 m³/day. Thus, the clean water needs of Negeri Passo Benteng Karang can be fully met through the implementation of the RWH method. Keywords: Clean Water, Rainfall, Rainwater Harvesting
