Abstract

This study aimed to assess the level of  vulnerability of  water resources on the climate variability of  Aesesa Watershed, NTT Province. Vulnerability assessments using IPCC concept, where the vulnerability as a function of  exposure, sensitivity and adaptive capacity. Criteria and indicators of  those function were obtained from previous studies, then given a score and weighting in accordance with the degree of  importance, spatially display and overlay, to produce vulnerability map. The results showed that the trend of  annual temperature in the upper watershed in recent years is decreased, while in the middle and lower areas are increased. The annual precipitation showed an  trend in the , while in the middle and  showed a declining trend. increasing upper area lower areas Related to water resources, the river's stream flows are relatively stable in the last five years. Water quality assessment in the river is categorized as lightly polluted in the upstream and moderately polluted in the downstream. Based on vulnerability map, the watershed is classified into highly vulnerable (54%), moderately vulnerable (13%) and lowly vulnerable (33%). Such results could be useful for the Watershed Authority and other stakeholders to establish strategies, plans and actions for addressing problems on vulnerability of  water resource.

Abstract

Penelitian ini bertujuan untuk mengetahui struktur komposisi jenis hutan mangrove di Desa Golo Sepang, Manggarai Barat. Indeks Nilai Penting (INP) dan Indeks keragaman yang diperoleh dari analisis vegetasi digunakan sebagai indikator untuk menggambarkan struktur dan keragaman hutan mangrove. Metode jalur dan garis berpetak digunakan dalam analisis vegetasi. Secara total terdapat 10 jalur dan 30 plot untuk mendapatkan data jenis-jenis mangrove, nilai parameter pertumbuhan (tinggi dan diameter) dan informasi terkait lainnya. Dari hasil penelitian diketahui bahwa terdapat 10 jenis dari 5 family yaitu Rhizophoraceae (Ceriops tagal (Perr), Rhizophora apiculata (Bi), R. mucronata Lmk., Bruguiera parviflora (Roxb.), B. sexangula (Lour) dan B. gymnorrizha (L.) Lamk.), Fabaceae (Derris trifoliata Lour), Meliaceae (Xylocarpus granatum Koen), Pteridaceae (Acrosthicum aereum Linn) dan Lythraceae (Phempis acidula Forst). R. apiculata (Bi) merupakan jenis yang paling dominan pada 7 dari 10 lokasi pengamatan. Pada dua lokasi yaitu di Sotri dan Muara kiri nilai INP jenis R. apiculata (Bi) mencapai 300%. Kerapatan individu/ha tertinggi terletak di Sotri yaitu 1.300 pohon/ha sedangkan yang terendah terdapat di Muara Kanan yaitu 100 pohon/ha. Keragaman jenis pada semua lokasi pengamatan masuk dalam kategori rendah dimana lokasi di Nampar Muara memiliki indeks keragaman paling tinggi yaitu sebesar 1,06.
