Abstract

   Some small islands in Balikpapan Bay consist of dry land which may have different vegetation structure and composition. Our study was the first to uncover vegetation conditions and soil proper-ties of dry land on small islands in Balikpapan Bay, which has never been conducted before. The research was carried out on Kalawasan and Karantina islands. Information on vegetation was obtained by applying a line transect method. Data on soil properties were col-lected by setting up 3 sampling plots in each transect of vegetation. Parameters used for analysing vegetation including relative densi-ty, relative frequency, relative dominance, Shannon-Wiener diversi-ty index, evenness index, and similarity index. Meanwhile, data on soils were analysed descriptively. Trees on Kalawasan island were comprised of 241 individuals belonging to 21 species. There were 61 individuals (22 species) of trees on Karantina island. The diver-sity index of trees on Kalawasan and Karantina island was 2.55 and 2.72, respectively. The tree evenness index was 0.84 on Kalawasan island and 0.88 on Karantina island. The index of similarity for trees between the two islands was 0.21. Furthermore, the soil character-istics on Kalawasan and Karantina islands showed similarities. In general, soil in Kalawasan and Karantina islands could be catego-rised as marginal soil which was common in East Kalimantan. Con-sidering the rapid loss of tropical forests in the mainland of Kali-mantan indicates that the small islands of Balikpapan Bay play an important role in future biodiversity conservation in East Kalimantan.

Abstract

The role of young generations including students was crucial in orang utan conservation. They are not only agent of change, but they are also capable of distinguishing attitudes which are able to influence policy in the future. The purpose of this study was to examine high school students’ perceptions of establishment of the orang utan sanctuary in Balikpapan Bay. We used quantitative and qualitative approaches for data collection with students on the grade of XII as respondent. Data was analyzed descriptively and quantitatively. The findings showed that students had good perceptions towards unreleased orang utan conservation. They agreed that the orang utan sanctuary should be established. Students also had positive perceptions relating to the positive impacts of orang utan sanctuary on the village and environment. However, students had neutral perceptions towards negative impacts of orang utan sanctuary. There were no differences between male and female students’ perceptions towards the establishment of orang utan sanctuary. Conversely, male and female students’ perceptions in regards with the impacts of orang utan sanctuary on the village and environment were differed.
