The benefits of local vegetables aside from being a food source that has the potential as a drug, pesticides, bioethanol and various other industrial materials. The majority of respondents aged over 40 years prefer vegetables (local) and food types were soup, while middle age (16-40 years) and young (under 16 years) can adapt to vegetables from outside and a new menu from outside Kalimantan. Factors for choosing the types of vegetables to be consumed are more influenced by taste reasons (54-86%), followed by habits (32-47%) and benefits for health (39-40%).

Reducing the negative impact of using synthetic insecticides in a friendly manner. The alternative is to use a bioinsecticide. Ujung Atap (Baeckea frutescens L.) essential oil is one of them that has the potential as a bioinsecticide. Distillation of fresh leaves and dry leaves. Aedes aegypti larvicide mortality test on the resulting essential oil. A. aegypti mosquitoes that cause dengue fever. Analyze the essential oil content of B. frutescens L. by GC-MS. The Dried Leaf Distillation of B. Frutescens L. produces more and better essential oil than fresh leaves. Dried leaf essential oil is more deadly against larvicides than fresh leaf essential oil of B. frutescens L. Larvacide activity is classified as toxic. There are 25 compounds found in essential oils of fresh leaves and 23 compounds in dry leaves. The compound which is a gastric poison for insects is Limonene.

This study investigates the selection agroforestry tree species based on a participatory approach and an ecological approach in Humbang Raya village and Tumbang Mantuhe village. This study method was carried out using a participatory approach through Focus Group Discussion (FGD) activities and an ecological approach through the identification of tree species in open and closed forests. The results of the FGD selected tree species in Humbang Raya village as many as 17 tree species and in Tumbang Mantuhe village as many as five tree species. The results of the identification of tree species in Humbang Raya village in closed forest amounted to 34 tree species, while in open forest there were 10 tree species. In Tumbang Mantuhe village in closed forest there are 29 species of trees and open forest five species of trees. It was concluded that the selected tree species to be planted on agroforestry land in Humbang Raya village and Tumbang Mantuhe village each had 4 tree species.

Conservation areas are known for their significant functions to protect the plant and animal biodiversity, as well as their ecosystems. Lapak Jaru Tahura, which is located in Gunung Mas Regency, Central Kalimantan, is one of the conservation areas with potential ecotourism attraction. The strategy for developing tourist objects and natural attractions in Tahura Lapak Jaru needs to be formulated to gain positive impact and to reach its sustainability. The purpose of this study was to dig ecotourism potential in Tahura Jaru Kuala Kurun and to formulate tourism development strategies in the Tahura Lapak Jaru in Kuala Kurun tourist area. This research was conducted through 2 (two) stages of analysis. First, identifying the tourism potential in the Tahura Jaru Kuala Kurun area with descriptive analysis. Second, formulating a tourism development strategy in the Tourism Area of the Lapak Jaru Kuala Kurun tourism area with a SWOT analysis. The results showed that the Lapak Jaru Tahura is a very potential site for further development to become a tourist attraction. The strategy of Tahura Lapak Jaru development is aggressive, namely, to use the strength they have to take advantage of current opportunities. These strategies, among others, are, first, to maintain its position as a tourism destination which fully supported by local government and the ease of gaining potential investor. Second, regional development planning needs to include the participation of local communities so that target consumers who tend to like nature tourism can be achieved.

This research was examine the potential for CO2 absorption and the provision of other ecosystem services of the Dipterocarpaceae-dominated Gunung Bondang Protection Forest in Murung Raya Regency, Central Kalimantan. The study focuses on potential carbon and ecosystem services in the form of CO2 sequestration, O2 production and payments in the form of Carbon creditsin the Gunung Bondang Protected Forest area.The study was conducted non-destructively using the parameters of the diameter and total height of the tree. The results showed the composition of the tree species was dominated by Dipterocarpaceae family, the potential biomass was 624.86 tons/ha, the potential C was 293.68 tons/ha and the potential of environmental services in the form of CO2 absorbed was 1,077.83 tons/ha, the production O2 was 786.81 tons/ha and the carbon credits was US$ 41,788/ha. Moreover, these result show the strong relevance of the Gunung Bondang Protection Forest for climate change mitigation. The protection and restoration of degraded forest parts contribute to the climate mitigation goals set by the Indonesian government, and the issuance of Carbon credits will be an important financial incentive for sustainable forest management and conservation.
