Abstract

The existence of unconventional mines (TI) which is increasingly prevalent nowadays has penetrated the coast, resulting in the mangrove ecosystem unable to develop properly. One of the areas affected by unconvencional minning activities is on the coast of Takari Beach, Bangka Regency. Takari Beach is one of the areas located on the coast of Rebo Village, Sungailiat District, Bangka Regency. One of the rehabilitation efforts carried out is by planting mangrove seedlings on Takari Beach in 2018 with a total of 500 mangrove seedlings. Mangrove rehabilitation activities are one form of land use conducted in Takari Beach. This activity also needs to be supported by the maintenance and monitoring of planting results to determine the success rate of mangrove planting activities on ex-tin mining land located in the coastal area of Takari Beach, Bangka. The results showed that the percentage of mangroves living at the observation station, namely on plot 1, was 71%. Plot 2's survival rate is 80%. The survival rate for plot 3 is 81%, the survival rate for plot 4 is 54%, and the survival rate for plot 5 is 27%. Plots 1,2 and 3 have a high survival rate, which is around 70-81%. Plots 4, and 5 have a low survival rate, which is around 27-54%. This can indicate that the success rate of mangrove survival can be said to be less successful. This could be due to the fact that there are still floating unconventional mining (TI) activities, which are operating again so that it is suspected that the tailings yield inhibits the growth rate and causes the death of mangrove seedlings.

Abstract

Ferns (Pteridophyta) have a high diversity of species and are able to live in a variety of environmental conditions. Ferns have an ecological function (ground cover, producer, bioindicator) and economically (as food, medicine, and crafts). The Jurang Nganten Waterfall in Jepara Regency is a tourist attraction as well as a source of irrigation for rice fields and gardens. The study aims to find out how the diversity of the fern species in the Jurang Nganten Waterfall Tourism Area. The research was conducted at three stations: Station 1 (entrance post), Station 2 (mahogany garden), and Station 3 (around the waterfall). Each station was divided into 7 plots with sizes 5 m x 5 m (terrestrial) and 10 m x 10 m (epiphyte). The results obtained 24 species included in 19  genera and 11 families (21 terrestrial species and 3 epiphytic species). The species of ferns that can be found at all stations are Nephrolepis biserrata, Antrophyum plantagineum, Pityrogramma calomelanos, and Pteris biaurita. The highest fern species diversity index (H’) is at around the waterfall, which is 2.51.

Abstract

Wana Wisata Curug Semirang is a tourist area in Semarang Regency based on ecotourism. As an ecotourism area, Curug Semirang contribute as conservation area in order to protection and preservation of nature. Along with tourism development, biodiversity in Curug Semirang is increasingly threatened. The purpose of this study is to examine the composition and structure of riparian in Wana Wisata Curug Semirang Area. The method used in vegetation is a quadratic plot with a line transect. Vegetation observation was carried out at 3 stations which were divided into 15 plots covering tree strata and poles. Vegetation analysis was obtained with the value of density, dominance, frequency, and important value index. The results obtained 75 plant species covering 42 families, in the tree strata there are 16 species in 12 families, and the pole strata there are 20 species in 14 families. The highest INP of tree strata at station 1 was pine (Pinus merkusii) 180.04%, stations 2 and 3 were kemadu (Laportea sinuata) 147.53% and 102.76%, respectively. The highest IVI of the pole strata at stations 1 and 2 is coffee (Coffea arabica) 123.98% and 140.5%, and station 3 is rotan (Calamus rotang) 113%.
