Abstract

ABSTRAKDAS Lagito merupakan salah satu DAS yang terdapat di Kabupaten Buton Utara yang terletak di  Desa Bubu, Kecamatan Kambowa. DAS Lagito di dalamnya memiliki potensi keanekaragaman vegetasi hutan dan sungai Lagito merupakan salah satu habitat burung maleo. Namun demikian belum ada data untuk mengungkapkan seberapa besar potensi hutan dan kondisi habitat di DAS Lagito. Untuk itu pengungkapan data dan fakta potensi keanekaragaman hutan di DAS tersebut sangat dibutuhkan. Hasil studi inventarisasi vegetasi  ditemukan komposisi jenis pohon sebanyak  97 jenis, diantaranya terdapat beberapa jenis yang memiliki INP tinggi yakni beringin (Ficus benjamina) INP 79,07, singi INP 39,72, jati (Tectona grandis) INP 18,87, bayam (Intsia palembanica) INP 9,20, bitti (Vittex coffasus) INP 9,18, roda INP 9,16 dan see (Tetradium glabrifolium) INP 9,10. Kata kunci: Keanekaragaman, Potensi Flora, DAS Lagito  ABSTRACTLagito watershed is one of the catchments in North Buton Regency located in Bubu Village, Kambowa District. Lagito basin in it has the potential for diversity of forest vegetation and the Lagito river is one of the habitats of maleo birds. However, there is no data to reveal the potential for forests and habitat conditions in the Lagito watershed. Therefore, the disclosure of data and facts on potential for forest diversity in the watershed is urgently needed. The results of vegetation inventory study found 97 species of tree species composition, some of which have high Important Value Index (IVI) ie beringin (Ficus benjamina) IVI 79,07, IVI singi 39,72, jati (Tectona grandis) IVI 18,87, bayam (Intsia palembanica) IVI 9,20, bitti (Vittex coffasus) IVI 9,18, IVI roda 9.16 and see (Tetradium glabrifolium) IVI 9.10.Keywords: Diversity, Flora Potential, Lagito Watershed

Abstract

Macrozoobentos are animals that live permanently in sediments at the bottom of the water, both on soft and hard substrate conditions. Macrozoobenthos contribute greatly to the function of aquatic ecosystems and play important roles such as mineralization processes in sediments and organic material cycles and play a role in transferring energy through the food chain. Based on the results of research conducted on the Lantahiwo River, Kotawo Village, West Kulisusu District, the species richness of macrozoobenthos found in the Lantahiwo River was varied where the number of individuals obtained from station 1 (upstream) was 20 individuals. At station 2 (middle of the river) there were 60 individuals, while at station 3 (downstream) there were 14 individuals. The river is a form of aquatic ecosystem that has an important role in the hydrological cycle and functions as a catchment area for the surrounding area. So that the condition of a river is strongly influenced by the characteristics of the surrounding environment. The sampling point includes looking at the considerations made in the field and sampling at stations 1, 2 and 3 is carried out in stages, first in the upstream, middle and downstream parts of the river then observations are made with several parameters that are considered important by researchers as key parameters that represent and describes the waters of the Lantahiwo River. This research was conducted from March to April 2020 in Kotawo Village, Kulisusu Barat District, North Buton Regency. Based on the results of identification, where the types of macrozoobenthos found in the Lantahiwo River at stations 1 to 3 consist of 2 families and 2 classes, namely; types of family Gerridae from class Bivalvia, species from family Thiaridae from class Gastropods, species from family Thiaridae from class Macrozoobentos were found at each station.
