This research aimed to find out local knowledge applied by the people of Tobelo Dalam tribe in the use of medicinal and edible plants. This research was carried out in Aketajawa Lolobata National Park at Aketajawe Block during April-June 2018. This research used a descriptive method through interviews and literature review. The selection of informants employed a snowball technique in which the main characteristics of the informants were the community leader, the traditional leader, and the community of the Tobelo Dalam Tribe. Data were analyzed using a qualitative analysis for data deepening on the ethnobotany study aspect based on the results of surveys and interviews obtained. The data were then analyzed using the Index of Cultural Significance (ICS) to determine the significance value of each plant species. The results showed that the number of plants used for treatment was 44 species dominated by those from the Malvaceae family such as achira or money tree (Pachira aquatica), cacao (Theobroma cacao), balacai or physic nut (Jatropha curcas L.) and dingo dingoto or climbing pandanus (Freycinetia sp). These plants are used for the treatment of mild wounds, allergic itching, postpartum and low stamina. Meanwhile, the number of edible plants often utilized by the people Tobelo Dalam Tribe was 7 species, covering Ipomoea batatas, Xanthosoma sp, Manihot utilisima, Oryza Sativa L., Metroxylon sagu, and Colocasia esculenta. These edible plants derived from 5 families dominated by Aracaceae (33%), Euphorbiaceae (17%), Convolvulaceae (17%), and Palmae (16%). The utilized parts of the edible plants were tubers and pith.
Riparians are undergoing extensive reductions and changes in their natural composition into agricultural and urban area. The relationship between the vegetation distribution pattern and the riparian topography factor has been assumed to typically represent a biome-specific or vegetation-specific constant. This study aim is to analyze the vegetation distribution pattern with topography along Alista river in Dau District, Malang. We surveyed 3 stations that represent a zone of edge gradient between the river and the mainland: levee, mid-flood, and slough. We used the wetland classification (Obligate -OBL; Facultative Wetland-FACW; Facultative Upland (FACU); and Upland (UPL) for each species found from various sources. we observed that facultative upland plants have a broad dominance. Mid-floodplain and slough dominated by typical upland species. Although Levee widely consisted of by upland plants, this area has one distinctive obligate species: Equisetum. The presence of OBL species in the levee and mid-floodplain indicate the area is receiving more frequent floods than other areas.
Mangrove Ecotourism Wonorejo Forest (EHMW) is designed by the Surabaya City's government to have some aspects of nature and education to conservation that may help to save the environment and economy, especially through the tourism. some ecologists revealed that the development of tourism in EHMW runs not balanced and not oriented to the principle of sustainability. This study aims to determine the level of sustainability of EHMW management in Surabaya based on analysis of three sustainability criteria. The study was conducted from September to October 2017. We conducted two methods of data collection: interviews and questionnaires. Assessment is grouped into four levels of sustainability status (%): 0.00-25.00 (unsustainable); 25.01-50.00 (less sustainability); 50.01-75.00 (sufficient sustainability); and 75.01-100,00 (continuous). EHMW management goes into sustainable criteria (77.18%). The value of the sustainability of all criteria is still below 50.1%, or less sustainable. Each criteria's value was ecology criteria of 29.38%, on the economic criteria of 28.17% and on the social criteria of 19.63%.
