Forest fires are one of the environmental problems that recur almost every year in Indonesia. This problem if not handled properly will certainly cause various negative impacts such as the emergence of haze that can interfere with public health and reduced forest cover, in forest areas. Taman Hutan Raya Nipa-Nipa (Tahura) as one of the Natural Preservation areas of Southeast Sulawesi Province is also inseparable from the problem of forest fires. The aims of the study were to analyze the level of forest fire vulnerability in the Tahura Nipa-Nipa area, especially in Watu-Watu Village, West Kendari Subdistrict, and the variables that most affect the level of forest fire vulnerability. Data analysis based on the weighting of each element is then carried out the determination of the vulnerability class using equations: forest fire vulnerability = {30 % x (land cover)} + {(20 % x height of place)} + {(20 % x Rainfall)} + {(10 % x distance from road)} + {(10 % x distance from river)} + {(10 % x distance from settlement)}. Mapping the class of forest fire vulnerability areas using geoprocessing with input data on land cover, place height, rainfall, and distance from roads, rivers, and settlements. Then an analysis is carried out and will be selected data according to the score of the level of forest fire vulnerability, namely very low/not a vulnerability with a score of 5, low with a score of 4, medium with a score of 3, high with a score of 2, very high /very vulnerability with a score of 1. The results showed that the level of forest fire vulnerability in Tahura Nipa-Nipa has 3 levels, namely the level of high forest fire vulnerability with an area of 68.51 ha, the level of moderate forest fire vulnerability with an area of 62.29 ha, and the level of low fire vulnerability with an area of 143.35 ha. The variables that most affect the level of forest fire vulnerability at the research site are land cover and community accessibility distance in the form of distance from the road and distance from the settlement.

Pranajiwa (Euchresta horsfieldii (Lesch.) Benn.) has been widely used as traditional medicine by the Balinese ethnic community. Up to now, the raw materials for traditional medicines from E. horsfieldii are harvested directly from their natural habitat. It is feared that it will interfere with its sustainability. The Balinese ethnic community has a culture known as the Tri Hita Karana (THK) concept, which means there is a balance in the relationship between humans and God, nature, and with fellow humans. This study aims to identify the use of E. horfieldii and its conservation efforts based on THK. This research was carried out in communities living around Bedugul, Bali. The method of data collection was done by participatory observation and semi-structured interviews. The research informants were 33 people with a purposive sampling method. The criteria are based on the level of knowledge and use of E. horsfieldii. Data were analyzed and interpreted descriptively. The results of this study indicate that E. horsfieldii has been widely used to treat various diseases and is practiced by many traditional healers (balian). However, people also use it for treatment without a standardized dose. This causes the measure of its use is very diverse. Harvesting of E. horsfieldii is carried out by the community while still observing the principle of sustainability according to the THK philosophy. Harvesting of E. horsfieldii is mostly done for individual needs. Although there has been a practice of buying and selling E. horsfieldii, harvesting has not resulted in over-exploitation. Efforts to conserve E. horsfieldii have been carried out by the community, especially the balians by trying to cultivate it, although they still fail. In addition, the conservation of E. horsfieldii is carried out by the Bali BKSDA with efforts to maintain the habitat of E. horsfieldii in forest areas.

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.
