Abstract

Mangrove, as one of the most unique ecosystems, is a great natural resource potential with high productivity and biodiversity able to adapt to harsh areas between the sea and coast. Its destruction rate is very mild as it is estimated to 1% each year (Ong et al., 1991) and 0.7-3% per year (Pedleton et al., 2012). The destruction of mangrove is usually related with human population density (Alongi, 2002). Widespread mangrove destruction affects the loss of biodiversity and other resources and the functioning of the ecosystem. The huge potential of mangrove must be preserved by managing, maintaining and providing costs to protect and improve ecosystems. This study aims to measure Kuala Langsa community members’ willingness to pay for the preservation and repairationof degrading mangrove. To achieve this goal, Contingent valuation methods was used in this study. Of the 131 respondents involved in this study, 112 or 85.496%  are willing to pay for the preservation of mangrove. While those unwilling to pay account for 19 or 4.504% . WTP with the households 669 earned by  is Rp 18,821,512,200/month or Rp 225,858,146,400/year.

Abstract

Butterflies are insects that live cosmopolitan. Some butterflies in tropical forests look for food sources from sucking the juice of ripe fruits that have fallen on the forest floor. Fruit-feeding butterflies can adapt in finding food sources, selecting and sucking food effectively. Fruit contains varying concentrations of sugar and nitrogen. The existence of fruit-feeding butterflies in tropical rain forests is influenced by the availability and quality of food sources as well as other supporting factors such as temperature, humidity, and light intensity. The purpose of this study was to identify fruit-feeding butterflies and their preferences for banana and pineapple baits in the Soraya Research Station Area, Leuser Ecosystem, Aceh, Indonesia from September to November 2020. Six forest trail locations were selected as trap locations. A total of 360 cylindrical gauze baited traps (80 cm high and 35 cm diameter) were installed on six trails/line transects. Baited traps were set at three different heights, that is at the understorey level (± 0-2 m), midstorey level (± 5-6 m), and overstorey level (± 10-11 m) with a distance of ± 5-10 m. The distance between location points is ± 250 m. The fruit baits used in this trap were ripe bananas and pineapples. The results obtained were 37 species with 176 individuals trapped on banana bait and 50 species with 183 individuals on pineapple bait. However, the results of the t-test using the Man-Whitney test showed no significant difference between the banana and pineapple bait used.
