Abstract

This study aims to determine; 1) Large use value, non-use value, and natural resource option value in the Tiworo watershed area; and 2) What is the total economic value generated in the Tiworo watershed area. The analysis technique used in this study consists of two, namely descriptive qualitative analysis (qualitative descriptive) and quantitative research. Quantitative analysis was carried out using the model: Productivity Method for Economic Value of Natural Resources in the Tiworo Watershed; Water residual value is done to estimate the economic value of water resources in the Tiworo watershed; and the Contingent Valuation Method (CVM) for Determining Tourism PAPs. The results of the study also show that the existing resources in the Tiworo watershed area are; a) Agriculture and plantations; b) Freshwater fisheries, c) Forestry; and d) Ecotourism. Based on the results of the valuation of the SDA Economy in the Tiworo watershed, use value is Rp. 459,563,876,989. Non-use value is Rp. 11,424,525,000. thus, a total economic value of Rp. 470,988,401,989 was obtained.

Abstract

The results of the study show that; 1) The air quality in Kota Raha according to the concentration of carbon monoxide (CO) ranges from 65.89-131.63 µg/m3, which is still below the ambient air quality standard according to the provisions of Government Regulation (PP) No.41 of 1999, which is permitted that is 30,000 µg/m3. The value of the Hydrocarbon (HC) concentration is in the range of 20.84-37.11 µg/m3, still below the ambient air quality standard according to RI PP No.41 of 1999 which is permissible at 160 µg / Nm3. Values ​​from the concentration of Nitrogen Oxide (NOx) ranged from 4.28-13.84 µg/m3, still below the ambient air quality quality standard, according to Republic of Indonesia Regulation No.41 of 1999 which is permissible at 400 µg/m3, and SOx concentrations ranged from 0.15-0.51 µg/m3, still below the air quality book according to RI Regulation No.41 of 1999 which allowed 900 µg/m3; (2) The current green road RTH in Raha City is 2.95 ha with carbon absorption capacity of 920.06 tons/year while Raha City produces emissions resulting in an emission load of 1,328,701 tons/year, meaning that there is around 408.64 tons/year remaining emissions not absorbed. Thus, green road RTH on the existing road has not been able to control or absorb gas from motor vehicle exhaust gases; and (3) The direction for controlling motor vehicle exhaust emissions based on the carrying capacity of the green lane in Kota Raha is to do extensive addition of RTH needs especially in reducing CO and HC by 28,024 m2 or 2,80 ha or about 30.75% of the total available RTH.
