Abstract

ABSTRAKPenurunan ketersediaan air dan peningkatan kebutuhan air telah terjadi di Kabupaten Konawe Provinsi Sulawesi Tenggara. Hal ini disebabkan karena perubahan penggunaan lahan akibat eksploitasi lahan secara terus menerus sehingga terjadi penurunan kapasitas infiltrasi dan peningkatan aliran permukaan. Berdasarkan permasalahan diatas maka diperlukan strategi pengelolaan dan pengembangan peran kelembagaan sehingga pengelolaan air baku untuk penyediaan air bersih di Kabupaten Konawe dapat berlangsung secara berkelanjutan. Penelitian ini dilakukan dengan tujuan: (1) menganalisis peran kelembagaan ditinjau dari aspek kendala yang dihadapi, kebutuhan program pemerintah terkait, dan lembaga yang berperan dalam pengelolaan air baku untuk penyediaan air bersih berkelanjutan di Kabupaten Konawe; dan (2) mengembangkan model kelembagaan pengelolaan air baku untuk penyediaan air bersih di Kab. Konawe dengan metode Interpretative Structural Modeling (ISM). Hasil penelitian menunjukkan bahwa untuk implementasi model, terdapat tiga elemen sistem yang perlu diperhatikan. Tiga elemen sistem dengan masing-masing sub elemen kuncinya yaitu: (1) kendala (menurunnya fungsi resapan air akibat berkurangnya vegetasi pada daerah tangkapan air, dan kurangnya koordinasi dan keterpaduan pengelolaan sumber daya air antar stakeholder terkait); (2) kebutuhan (peningkatan pengetahuan dan ketrampilan aparat SKPD terkait, dan peningkatan kesadaran stake holder terkait); dan (3) lembaga (BP DAS Sampara, Forum DAS Sultra dan Dinas Kehutanan Kab. Konawe). Kata kunci: model, kelembagaan, air baku, air bersih, ISM   ABSTRACTDecreased water availability and increased water demand has occurred in Southeast Sulawesi Konawe. This is caused by changes in land use due to continuous exploitation of land resulting in a decrease in infiltration capacity and increased surface runoff. Based on the above issues will require the development of management strategies and the role of institutions, so that the management of raw water for water supply in Konawe District can take place in a sustainable manner. This study was conducted with the aim of: (1) analyze the role of institutional on the aspects of constraint, the needs related government programs, and agencies that play a role in the management of raw water for water supply sustainable in Konawe district, and (2) develop a model of water management institutions of water supply in the Konawe District with Interpretative Structural Modeling method (ISM). The results showed that for the implementation of the model, there are three elements of the system that need to be considered. Three elements of the system with each of the key sub elements, namely: (1) constraint (decreasing function of water absorption due to reduced vegetation in the catchment area, and the lack of coordination and integration of water resources management among related stakeholders), (2) needs (increased knowledge on education and skills related apparatus, and an increased awareness of all related stakeholders), and (3) agency (BP DAS Sampara, Forum DAS Sultra and Dinas Kehutanan Konawe District) . Keywords : models, institutional, raw water, clean water, ISM

Abstract

Heavy metal is one of the most pollutant loads that endangers the aquatic environment. Not only damaging the aquatic ecosystem, the presence of heavy metals also endangers the human health. This Research aims to determine the levels of heavy metals, especially Pb, Cu and Zn in water and also the sediments inside Kendari Bay waters. To determine the environmental quality of Kendari Bay waters standards, Sampling was carried out at 10 stations and sample analysis was carried out using the AAS method. Data analysis was performed using descriptive methods. The results showed that heavy metals Pb, Cu and Zn in water ranged <0.002 - 0.012 mg / L, for metals ranging from <0.002 - 0.003 mg / L, Cu metals ranged from <0.002 - 0.012 mg / L and Zn metals ranged from <0.002 - 0.003 mg / L, while heavy metals Pb, Cu and Zn in sediments range <0.002 - 0.047 mg / kg, for Pb metals range from 0.052 to 0.047 mg / kg, Cu metals range <0.002 - 0.042 mg / kg and Zn metals range from 0 , 0019 - 0.011 mg / kg. The heavy metal content of Pb, Cu, and Zn in both water and sediment samples has not exceeded the quality standards based on the Decree of the Minister of Environment No.51 of 2004 and USEPA.Keywords : kendari bay, heavy metal, Pb, Cu, Zn

Abstract

South Konawe Regency experienced a decrease in water supply and an increase in water demand, due the changes in land use caused by ongoing land exploitation, which increases runoff and decreases infiltration capacity. As a result, more water is lost to the ocean, threatening the water supply from Laeya River. Laeya River raw water is not only utilized for PDAM raw water sources, but also used to meet the domestic needs of the community, agricultural irrigation and plantations, so it is important to know the its sustainability status. This research aims to carrying out activities that control the water quality of the Laeya River, as well as to serve an information regarding the status model for the sustainability of raw water management, and to raise environmental awareness. This study was carried out in the Laeya River, South Konawe Regency. Sampling was conducted at three stations representing the upstream area of the Laeya River, the middle area and the downstream area. The Multi Dimensional Scaling (MDS) analysis method was used to conduct an analysis of the status of sustainable natural resource management for sustainable raw water supply. Based on the results can be concluded that Analysis of the 41 attributes derived from five dimensions resulted in 12 attributes acting as leverage factors in each dimension partially. To improve the sustainability status of raw water management in the research area, it is necessary to intervene the 12 attributes, namely 11 attributes that need to increase the intensity of their activities, and one attribute needs to be controlled and planned for its development properly. The results of the assessment of 41 attributes from five dimensionsin the management of the Laeya River for raw water supply in South Konawe Regency, currently is at less Sustainability status(Sustainability Index value of 36.63).KeywordsSustainability Raw WaterMDSMonte CarloRAPS-LaeyaSouth Konawe Regency
