Abstract. Merang OP, Lahjie AM, Yusuf S, Ruslim Y. 2020. Productivity of three varieties of local upland rice on swidden agriculture field in Setulang village, North Kalimantan, Indonesia. Biodiversitas 21: 49-56. Swidden agriculture field is a dry land used by traditional farmers to cultivate some varieties of local upland rice intercropped with vegetables, tubers, and fruits. This rotational cultivation system utilizes the land for planting such food crops in one year period before it is left for fallow periods for years. This study aimed to assess the productivity of local upland rice varieties (i.e. Langsat rice, Telang Usan rice, and Pimping rice) cultivated on swidden agriculture field in regard to the fallow periods. This study was conducted in Setulang village, Malinau District, North Kalimantan Province and employed purposive sampling method using interviews of selected respondents and field observation. Among three varieties of rice in this study, Langsat rice had the longest fallow period with 17 years while Pimping rice had the shortest fallow period with 13 years, with the maximum production were 2,635 kg ha-1 and 1,670 kg ha-1, respectively. Meanwhile, Telang Usan rice reached the maximum production on fallow period of 15 years with the total production of 2,208 kg ha-1. Overall, of the three types of rice planted, the results show that the longer the fallow period, the higher the rice production and the shorter the fallow period, the lower the production. Each type of rice has a different amount of production, although it is planted during the same fallow period.

Abstract. Kristiningrum R, Lahjie AM, Masjaya, Yusuf S, Ruslim Y, Ma’ruf A. 2020. Fauna diversity, production potential and total economic value of mangrove ecosystems in Mentawir Village, East Kalimantan, Indonesia. Biodiversitas 21: 1940-1953. Mangroves play important role in life. The benefits of the mangrove ecosystem consist of ecological and socio-economic values. However, it is a challenge to discern how the mangrove ecosystem provides a comprehensive economic value. This research is aimed to analyze the Total Economic Value (TEV) of mangrove ecosystems in Mentawir Village, North Penajam Paser District, East Kalimantan Province. This aim will be achieved by conducting fauna inventory, analysis of mangrove wood production potential, social-economic interviews, and infrastructure cost analysis as the inputs to calculate four elements (i.e. Direct Use Value, Indirect Use Value, Option Value, and Existence Value) to sum up the TEV. The research used a mixed-method combining both qualitative and quantitative methods. Fauna inventory was conducted using boat survey method and interviews with local fishermen. Data on mangrove wood production was obtained using the systematic random sampling method by establishing two plots with an area of one hectare for each plot to calculate mean annual increment (MAI) and current annual increment (CAI). The economic value of the mangrove ecosystem was calculated using market price values, replacement costs, and the Contingent Valuation Method (CVM). The results of fauna inventory consisted of 3 species of mammals, 1 species of reptile, 16 species of birds, 25 types of fish, 8 species of crustaceans, and 7 species of mollusks. The economic valuation resulted in the contribution of direct use value with 39.56% in the form of wood (94,875,000,000 IDR) and fishery products (103,500,000,000 IDR); indirect use value with 53.47% in the form of breakwater (38,028,881,407 IDR), abrasion resistance (218,549,528,110 IDR), and carbon sequestration (11,580,313,067); option value with 6.92% in the form of biodiversity (34,690,085,038 IDR); and existence value with 0.05% (241,500,000 IDR). All these resulted in the total economic value (TEV) of the mangrove ecosystem in Mentawir Village of 501,465,307,621 IDR. Therefore, this value can be the basis for policymakers in managing natural resources so that the ecosystem is more protected and sustainable, and can continue to provide environmental services for the welfare of the community.

Abstract. Siahaya ME, Matius P, Aipassa MI, Rayadin Y, Ruslim Y, Aponno HSES. 2021. Potential analysis of location, socio-culture and biodiversity as ecotourism attraction in Valentine Bay on Buano Island, West Seram, Maluku, Indonesia. Biodiversitas 22: 438-448. This study aims to analyze the potential of flora and fauna in the mangrove ecosystem as an attraction for ecotourism development, knowing the role of stakeholders in supporting ecotourism development strategies in the mangrove area of Valentine Bay in Buano island, West Seram, Maluku (Moluccas), Indonesia. Based on the results of the study, it was found that (i) The mangrove vegetation had 28 species of plants under 19 families. Vegetation at the level of seedlings, saplings, and trees was found, the dominant species being Rhizophora apiculata, Bruguiera gymnorrhiza, and Xylocarpus granatum. The diversity of animals in the Valentine Bay mangrove ecosystem consist of birds, insects, reptiles, mollusks, crustaceans, echinoderms, fish, and mammals. Furthermore, there was an endemic fauna of Buano island, namely the Kehicap buano/black-chinned monarch bird (Symposiachrus boanensis) which has started to become rare, and was declared as critically endangered (CR) by the International Union for Conservation of Nature and Natural Resources; (ii) Stakeholder involvement in ecotourism activities were very supportive; (iii) Development strategies were to develop ecotourism, promote ecotourism attractiveness, develop educational tourism and promote study on the diversity of flora, fauna, culture, and traditional customs on Buano island.

Abstract. Siahaya ME, Matius P, Aipassa MI, Rayadin Y, Ruslim Y, Aponno HSES. 2021. Ecotourism development through biodiversity potential identification and community perception in the protected forest on Buano Island, Western Seram, Maluku, Indonesia. Biodiversitas 22: 3179-3191. Forest as part of a large ecosystem has an important meaning and role in supporting living systems. Various great benefits can be obtained from the forests through its functions as a provider of water resources for humans and the environment, the ability of carbon sequestration, oxygen suppliers in the air, global climate regulators, and tourism service providers. The community has important role and participation in ecotourism that are different from other forms of tourism. Perception is a fundamental element that needs to be known before planning several activities that will involve the local community. This study aims to identify the potential of flora and fauna in the protected forest area for tourist attraction and analyze the Buano island community’s (Western Seram District, Maluku Province, Indonesia) perception of ecotourism development activities. The vegetation data were collected using the combination of the path method and the compartmentalized line method. The method used for collecting wildlife data in the field is the line transect method as well as direct and indirect observations. Meanwhile, data related to community perceptions were collected through questionnaires and interviews. The results show that the villages on Buano island have biodiversity and cultural potential that could be developed as ecotourism attractions. In addition, the community’s perception supported that they strongly agree on the development of ecotourism in the villages of Buano island.

Abstract. Mursidah, Lahjie AM, Masjaya, Rayadin Y, Ruslim Y, Judinnur MB, Andy. 2021. The dietary, productivity, and economic value of swiftlet (Aerodramus fuciphagus) farming in East Kalimantan, Indonesia. Biodiversitas 22: 2528-2537. Edible-nest swiftlets have many health benefits. The availability of edible-nest swiftlets from caves is decreasing, while the demand for edible-nest swiftlets is getting higher. Swiftlet farming is carried out to meet this demand. The location of swiftlet farming should be close to the feeding sources. Swiftlet is flying insectivorous animals. A financial feasibility assessment is carried out to determine the feasibility of the business. This study aims to determine the composition of land cover, determine the insect order of feed sources, and analyze the production and financial feasibility of swiftlet farming. The study was carried out from June to December 2019. The composition of land cover was determined using the supervised classification method, the order of insects was known using the insect determination key, while production and financial feasibility were analyzed using the Net B/C, NPV, IRR, and PP methods. The observed location and swiftlet farming were determined purposefully. The results of this study show that the land cover was dominated by shrubs (56.58%) and secondary forest (27.3%); both types of land cover are suitable for swiftlet farming locations. The dominant insects found in shrubs and wetland shrubs are Diptera (78.25%), in rice fields are Diptera (86.7%) and in oil palm plantations are Diptera (29.4%) and Hymenoptera (27.78%). Edible-nest swiftlets harvest begins in the third year, with a production period of between 17-34 years. From the financial feasibility, it can be concluded that swiftlet farming is feasible.
