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 rapid pace of development in Kendari has had an inevitable negative impact on environmental quality, including water quality degradation in Wanggu River. River water quality degradation is influenced by anthropogenic activities such as felling trees for land clearing, agricultural waste, and disposal of organic and inorganic waste into river bodies. These activities certainly affect the decline in the water quality of the Wanggu River. This study aims to determine the water quality status of Wanggu River based on the pollution index method. This study was conducted in September - October 2019. To find out the water sampling points, the stations were determined, namely station I, station II, and station III using the observation method. Water samples at the three stations were tested for water quality at Laboratory of Biology, Faculty of Mathematics and Natural Sciences, Halu Oleo University, to analyze physical parameters (temperature, TDS, and TSS), chemical parameters (pH, DO, BOD, COD, Nitrate, Nitrite, Oil and Fat, Detergent), and Microbiological Parameters (Total Coliform). Determination of the water quality of the Wanggu River was carried out using the Pollution Index Method. Based on the results of the Analysis of Pollution Index Method, the water samples from Wanggu River at stations I, II, and III obtained pollution index values of 1.62, 1.79, and 1.73 respectively. Therefore, the pollution index of the Wanggu River at the three stations was at a lightly polluted quality status. Besides, some parameters that did not meet quality standards included chemical parameters, namely Biological Oxygen Demand (BOD) and Dissolved Oxygen (DO), so that the water quality status of Wanggu River was classified as lightly polluted based on class 3 (three) water quality standards set by Government Regulation No. 82 of 2001.

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 purpose of this study is 1) to identify changes in land use through the interpretation of Landsat imagery from 2007 to 2017 in the Baubau watershed and 2) to analyze the critical level of land and land use planning through land rehabilitation techniques and land conservation. The level of critical land was analyzed based on Scoring through GIS using four types of data, namely Landsat 2017 imagery, scoring standards for critically protected forest areas, protected areas outside the forest area and cultivation areas for agricultural business. The land use plan is based on the 2017 land capability and land cover classes that are overlaid with the use zone (Space Pattern) using the ArGis 10.3 application. The results showed changes in land cover / use from 2007 to 2017 i.e. secondary dryland forests with an area of 2,830.2 ha turned into shrubs, open land, mixed bush dryland agriculture, dry land agriculture and plantations with an area of 756.77 ha (26.74%) . Plantations with an area of 814.06 ha are turned into open land, dry land mixed with bush farming and 34.17 ha (4.20%) of settlements. Shrub land with an area of 1,196.77 ha has been turned into secondary dryland forest, open land, mixed-bush dry land agriculture, dry land agriculture and plantation with an area of 717.71 ha (59.97%). Bush mixed dryland agriculture with an area of 442.73 ha turned into secondary dryland forest, open land, settlements and plantations with an area of 99.58 ha (22.49%). Dry land agriculture with an area of 1,336.3 ha has been transformed into secondary dryland forest, shrubland, mixed shrub agriculture and plantation with an area of 370.81 ha (27.75%). Rice fields with an area of 200.91 ha are plantations and settlements with an area of 8.84 ha (4.40%). Savana with an area of 165.38 ha turned into a settlement of 7.72 ha (4.67%). While the open land with an area of 49.8 ha turned into secondary dryland forest, shrubs and plantations of 24.87 ha (49.94%). The results of the analysis of critical lands show that the Baubau watershed area with a rather critical category of 2,691.25 ha (33.62%), uncritically 2,564.76 ha (32.04%), critical potential 978.55 ha (12.23%), critical 674.61 ha (8.43%) and very critical 119.04 ha (1.49%).
