The water utilization in Grojogan Sewu Nature Tourism Park has been used by community around it to fulfill their water needs such as cooking and farming. In the other hand, it is presumed that they have still lack of awareness and appreciation about the conservation object. One of the efforts to increase the community awareness for the water conservation in Grojogan Sewu Nature Tourism Park is to inform the economic value of the water they use every day. This study aims to analyze the economic value of domestic water use and agricultural irrigation that has been carried out by the community around the Grojogan Sewu TWA area. The research method used in this research is quantitative and qualitative methods. The results showed that the economic value of the use of domestic water and agricultural irrigation by the community around the TWA Grojogan Sewu area was Rp238,565,600,000/month and Rp7,548,750.00/year. This result shows that the economic value of water utilization in TWA Grojogan Sewu is quite high, although the community is not aware of it. This can be illustrated by the value of the community's willingness to pay for the use of water which is still in the fairly low category, which is only Rp7,687,00/month for domestic water use and Rp6,818.00/month for the use of agricultural irrigation.Keywords: water for domestic, agricultural uses, economic value, Grojogan Sewu Nature Tourism Park

The volume estimation model is one of the most important components in developing sustainable forest management. Nowadays, various models for various types of forests in Indonesia have developed. Nevertheless, these models do not represent the type of forest ecosystem in Papua. Therefore, numerous studies are still needed to develop volume estimation model for various types of forests in Papua. This study was aimed to develop timber volume estimation model for commercial tree species in logging concession of PT. Tunas Timber Lestari in Sesnukt District, Boven Digul Regency, Papua Province. A total of 164 trees were chosen to develop the model and 50 trees for model validation. The result showed that diameter did not have a strong correlation with tree height. Therefore, the model should be developed using the combination of diameter and tree height. The best model in the development stage was selected based on the value of coefficient of determination (R2), standard error of the estimate (SEE), and Ftest. The best model in the validation stage was selected based on the value of bias (e), root mean square errors (RMSE), average deviation (SR), aggregative deviation (SA), and χ2test.. The best model for timber volume estimation in PT. Tunas Timber Lestari are V = 0.00007594 D1.978 H0.923. Keywords: commercial tree species, diameter, timber volume estimation, tree height, volume
