Abstract

Watershed as an ecosystem has survival benefit for humans and other living organisms, in which there is forest that has many services, such as: water management, flood control soil erosion protection, soil fertility maintainance, nutrient preservation and environmental balance conservation. Sub watershed Lewara is one of the sub-watershed that provide water supply in the watershed area of Palu. However, reduction on vegetation cover along the riverbank of Lewara lead erosin and increased the run off which is also a cause sedimentation. This study aimed to calculate water discharge and sediment drift produced by sub watershed of Lewara at Balane Village, Sub district of Kinovaro. The method used in the study is a field survey and measurement directly water discharge and sediment at the field through determination of three points in the upstream, midstream, and downstream. The results of the study indicate that water discharge and drift sediment concentration in the study period that discharge of water with an average value of 1,8506 m3/s and drift sediment concentration with an average rating of 0,000081 g/l. Based on the results obtained indicate water discharge has a strong corelation with the drift sediment total with correlation value of 0.621, and a strong correlation of rainfall and drift sediment total with the correlation value of 0.699. This may be concluded that the increased rainfall would be followed by increased water discharge and drift sediment load concentration by river flows. Keywords: watershed, water discharge, drift sediment

Abstract

Termites play important roles in organic matter decomposition, nutrient cycling, and soil structure in tropical rain forests. When forests are replaced by agriculture, termite species richness, abundance, and function often decline. This research was aimed to determine diversity and composition of termites in three land use types (community forest, simple and complex agroforestry). The method used in this study is collecting termites sampled on transects measuring 2 x 100 m, divided into 20 sections (2 x 5 m). The collected samples were collected for identification purposes. Variables measured the diversity of termites which includes the type and number of species (species richness) found in each land use. Diversity and abundance of species of termites were analyzed using the Shannon Diversity Index-Wienner (Shannon & Weaver, 1994 in Magurran, 2004). The results showed that the total number of termite species founded in both area was 6 species comprising 2 families, i.e; termitidae and rhinotermitidae. Alpha diversity of termite founded in community forest was 4 species, and 5 species founded in complex agroforestry and 3 species founded in simple agroforestry. The highest frequency of termite species was 0,5 that achieved by Odontotermes sp in community forest and simple agroforestry, while the lowest frequency was 0,05 that achieved by Schedorhinotermes sp. in community forest. Further, the Shannon species diversity Index (H’) of each land use types were 0,93, 0,95 and 1,47 in simple agroforestry, community forest and complex agroforestry, respectively. Keywords: Diversity, Termites, Land use types.
