Abstract

Land supply that is fixed while the demand continues to grow makes the land use of a city change toward more profitable activities seen from the surrounding potential. Increasing population and socioeconomic pressure have resulted in the widespread use of natural resources that are not in accordance with their uses, for example encroaching forest areas to build settlements and open land for gardening. Kebun Raya Kendari as anplant conservation area ex situ has a function of conservation, research, education, tourism and environmental services having an area of 96 with conservation plants that are our main and distinctive collection, namely ruruhi (Sisgium sp), singi (Dilenia Serrata Thumb), dan lobe-lobe. Good management of the Kebun Raya Kendari is in need of accurate data and information support. Now, by utilizing the technology capabilities of Geographic Information System and remote sensing, data and information about land cover in the Kebun Raya Kendari can be processed more efficiently. The purpose of this study is to determine changes in land use in the Kebun Raya Kendari. Data analysis of land use change is done by identifying the shape of objects in the satellite imagery that are in the research location. Landsat image interpretation to identify land uses in 1998, 2003, 2008, 2013 and 2018 is done visually. The validation of identification results on field conditions is based on the results of accuracy testing (Ardiansyah, 2014). The land use classification accuracy test is performed statistically by calculating overall accuracy based on a confusion matrix and kappa accuracy. Land use in the Kebun Raya Kendari in 1998, 2003, 2008, 2013 and 2018 was dominated by primary dryland forests and secondary dryland forests. In the period 1998-2018 there was a change in land use dominated by changes in primary dryland forest to open land.

Abstract

The development of industries and settlements along the Wanggu River and several other rivers that flow into Kendari Bay have affected the quality of river water and have an impact on the deterioration in the quality of water resources and the environment. The decline in water quality is characterized by changes in physical water, namely changes in water color, odor, and taste. A river is said to be polluted if its water quality is not in accordance with its designation. The purpose of this study was to determine the abundance of macrozoobenthos and the quality of river water which empties into Kendari Bay.This study uses a survey method, the information collected at each trailer station represents the entire population. Sampling uses a purposive sampling method with five replications per station. Sampling of macrozoobenthos, measurement parameters namely temperature, pH, DO, COD, BOD, organic matter, Substrate. Based on macrozoobenthos observations found during the study consisted of 16 types, which were classified into 5 classes and 3 phyla with composition Bivalvia (43.75%)class Gastropod (25%), and Polychaeta (18.75%), Insect Class (6, 25%) and Oligochaeta Class (6.25%) with macrozoobenthos density values ranging from 25 - 125 Ind / m². Diversity index values at the six stations are categorized as low diversity with an average value of H '= 1.27. The river that flows into Kendari Bay is polluted, this is confirmed by the results of environmental chemical tests. Parameters that exceed quality standards for Class II waters are COD and BOD.

Abstract

The calibration result of Tank Model on DTA SPAS Cumucang-Cimandiri by using rainfall data, evapotranspiration and land cover in 2009 shows that the determination coeffient  equal to 0,77 to aktual discharge and model output discharge. Validation results using 2014/2015 datas shows a strong relationship between the actual discharge and the model output discharge with a determination coefficient of 0,805 and generate an average daily discharge value of 1,057 m3sec-1, a maximum discharge value of 6,68 m3sec-1, and minimum discharge value of 0,072 m3sec-1. The Model show the hydrological conditions are in moderate category with KRS value of 93,2238. Based on the analysis of internal and external factors using SWOT analysis, it was found that the management strategy of DTA SPAS Cimuncang-Cimandiri was in the SO position (Quadran I).  The conservation strategy is to keep the forest area in a state of > 30% and optimize environmental funds and services to foster people's creativity to improve welfare. As an alternative strategy that can be applied to keep the DTA SPAS Cimuncang-Cimandiri remains in  good conditions  is to make efforts of soil and water conservation such as absorption wells on settlements and making terraces on rice fields. The implementation of this conservation strategy can reduce the value of KRS to obtain of 54,326.
