Abstract

Transformasi hujan-limpasan telah dilakukan pada DAS Cidanau, Benten menggunakan Model Hidrologi HBV-96 pada periode 2010-2011 sebagai periode kalibrasi dan 2012 sebagai periode validasi. Tujuan dari penelitian ini adalah untuk menganalisis kinerja model subtropis HBV-96 ke daerah tropis DAS Cidanau, Banten. Model HBV-96 dikalibrasi secara manual melalui uji coba penyesuaian parameter untuk mendapatkan kondisi fisik yang sesuai dengan DAS Cidanau. Hasil penelitian menunjukkan bahwa model dapat mentransformasi hujan menjadi debit limpasan dengan cukup baik dengan nilai korelasi (r) dan NSE pada kalibrasi sebesar 0,829 dan 0,672. Hasil perhitungan neraca air menunjukkan perbedaan total debit observasi dan total debit simulasi tidak terlalu jauh berbeda, yaitu sebesar 2253 mm dan 2139 mm. Hal ini menunjukkan model HBV-96 yang diaplikasikan di DAS Cidanau cukup baik dalam mentranformasikan data hujan menjadi limpasan dan perhitungan neraca air, walaupun belum baik dalam menggambarkan debit puncak. Rainfall-Runoff transformation has been carried out at Cidanau watersheed, Benten using the Hydrology Model named HBV-96 in the period 2010-20011 as calibration and 2012 as validation. The purpose of this study is to analyze the performance of the HBV-96 as a subtropical model to the tropical area of the Cidanau watershed, Banten. The HBV-96 model is calibrated manually through a parameter adjustment test to obtain physical conditions that are in accordance with the Cidanau watershed. The results show that the model can transform rain into runoff discharge quite well with correlation values (r) and NSE of 0.829 and 0.672. The results of the water balance calculation show that the difference between the total observation discharge and the total simulated discharge is not too different, which is 2253 mm and 2139 mm. This shows that the HBV-96 model applied in the Cidanau watershed is quite good in transforming rainfall data into runoff and water balance calculations, although it is not good in describing peak discharge.

Abstract

Hutan pantai memiliki peran ekologis yang penting dalam menjaga keseimbangan ekosistem pesisir, termasuk dalam menyerap karbon dan mendukung keanekaragaman hayati. Penelitian ini bertujuan untuk menganalisis keanekaragaman jenis pada berbagai tingkat pertumbuhan vegetasi dan menduga cadangan karbon atas permukaan di hutan pantai Negeri Hatusua, Kecamatan Kairatu, Kabupaten Seram Bagian Barat, Maluku. Analisis keanekaragaman menggunakan indeks Shannon-Wiener dan pendugaan cadangan karbon dilakukan dengan metode non-destruktif dan destruktif, mencakup pohon, nekromas, tumbuhan bawah, dan serasah. Hasil penelitian menunjukkan bahwa tingkat semai memiliki nilai keanekaragaman tertinggi (H’ = 2.48), diikuti oleh pancang (H’ = 2.18), pohon (H’ = 1.59), dan tiang (H’ = 1.22). Kerapatan vegetasi mencerminkan pola regenerasi alami hutan, dengan tingkat semai mencapai 130,500 individu/ha, namun mengalami penurunan signifikan pada tingkat pancang (1,920 individu/ha), tiang (460 individu/ha), dan pohon (100 individu/ha). Sedangkan total cadangan karbon atas permukaan mencapai 89.41 ton/ha, dengan pohon sebagai penyimpan karbon terbesar (83.87 ton/ha atau 93.81% dari total karbon), dan serapan karbon dioksida mencapai 327.83 ton/ha ekuivalen. Beach forests play a crucial ecological role in maintaining the balance of coastal ecosystems, including carbon sequestration and biodiversity support. This study aims to analyze species diversity at various vegetation growth stages and estimate aboveground carbon stocks in the coastal forest of Negeri Hatusua, Kairatu District, West Seram Regency, Maluku. Diversity analysis was conducted using the Shannon-Wiener index, while carbon stock estimation was carried out using non-destructive and destructive methods, covering trees, necromass, understory vegetation, and litter. The results show that the seedling stage has the highest diversity value (H’ = 2.48), followed by the sapling (H’ = 2.18), tree (H’ = 1.59), and pole (H’ = 1.22) stages. Vegetation density reflects the natural regeneration pattern of the forest, with seedlings reaching 130,500 individuals/ha, but significantly decreasing at the sapling (1,920 individuals/ha), pole (460 individuals/ha), and tree (100 individuals/ha) stages. The total aboveground carbon stock was found to be 89.41 tons/ha, with trees serving as the most significant carbon reservoir (83.87 tons/ha or 93.81% of the total carbon). In comparison, carbon dioxide sequestration reached 327.83 tons/ha equivalent.
