Abstract

Tujuan penelitian ini adalah untuk mengetahui fisiognomi vegetasi tumbuhan yang ada di hutan Bukit Kangin desa adat Tenganan Pegringsingan, Karangasem, Bali. Penelitian ini termasuk penelitian eksploratif dan deskriptif. Populasi penelitian ini adalah seluruh spesies tumbuhan berguna yang ada di hutan Bukit Kangin, Tenganan Pegringsingan. Sampel penelitian ini adalah seluruh spesies tumbuhan berguna yang terkover oleh kuadrat ukuran 1x1 m2 untuk pendataan spesies tumbuhan habitus seedling (semai/tumbuhan bawah), 10x10 m2 untuk saplings (pancang,tiang), dan 20x20 m2 untuk tumbuhan habitus matures/trees (pohon).

Abstract

This research aims to find out (1) the plants that were used in religious ceremonies (Hinduism) in accordance with the Bali Aga Tenganan Pegringsingan culture. 2) the making process of the various means needed in religious ceremonies (Hinduism) related to the utilization of useful plant species in Bukit Kangin Forest, Tenganan Pegringsingan Village. The Research was explorative (vegetation) and socio-system (community) research. The populations of this research were ecosystem aspects and sociosystem aspects. The ecosystem aspects included all of the useful plant species in Bukit Kangin Forest of Tenganan Pegringsingan village. Meawhile, the sociosystem aspects included the village officials, the village public figures and the community of Tenganan Pegringsingan village. The ecosystem sample (the vegetation) used in this research included the plant species in the forest of Tenganan Pegringsingan Village covered by the 1x1m2 sized seedling square, 10x10m2 sized sapling square and 20x20m2 sized square for trees (mature plants). There were 65 squares in total. The sociosystem samples in this research were the village officials, public figures, shamans, offerers, craftsmen, and the public in Tenganan Pegringsingan village. The methods applied in this research were (1) square method for ecosystem (vegetation) parameter. (2) Interview, questionnaire and observation for sociosystem parameter. The collected data were further analyzed descriptively. The results of the research showed that (1) of 46 useful plant species found in Bukit Kangin forest of Tenganan Pegringsingan, 29 of them were plant species that were utilized for religious ceremonies (Hinduism), meanwhile there were 17 plant species utilized for clothing, food, shelter, industry, medicine, and other household purposes.

Abstract

The objectives of this study were: (1) to determine the benefits of plant species in the Taman Gumi Banten area based on local village wisdom. (2) produce maps of vegetation, general distribution of plants and offerings in their natural nature. This research is included in exploratory research. The locations of this research all took place in the forests of Taman Gumi Banten and the villages of Wanagiri, Sukasada, Buleleng. The population of this research is (a) Vegetation Mapping: the entire forest area of Taman Gumi Banten. (b) Social: The entire Wanagiri village community. Research samples: (a) Vegetation mapping: forest boundaries of Taman Gumi Banten. Social: Service Village 5 people, Traditional Village 5 people, Balian 2 people, Banten Tukang 5 people, Community Leaders 10 people, General public 50 people. Total 77 people. Sampling methods: (a) Vegetation mapping: total sampling. Social: Systematic sampling. Data collection methods: (a) Vegetation Mapping: Simple measurement technique. Useful Plants / Plants of Banten: quadratic method. Social: interviews, observations, and questionnaires. The results showed: (1) The plant species that make up the ecosystem in Taman Gumi Banten, Wanagiri Village consist of 67 species. The composition of the species of offerings in the forest of Taman Gumi Banten, Wanagiri village, consists of 25 species of plants that can be used as for making traditional offerings. Of the 25 species of banten plants, the body parts or plant organs used were 1 species (4.35%) of roots, 3 species of stems (13.04%), 9 species of leaves (39.13%), 4 species (17.39%), fruit as many as 8 species (34.78%), and 1 species used tuber parts (4.35%). Thus, the most widely used parts of the existing plants in the Gumi Banten forest to be used as infrastructure for offering materials are the leaves and fruits. (2) General plant vegetation map and Banten plant map have been produced.

Abstract

Stranded Sunfish in North Bali with full body we collect to do molecular identification. Samples were amplified at the d-loop locus (control region) using the PCR (Polymerase Chain Reaction) method. Primers used in PCR are H16498 as primary front (forward) and L15812 as reverse primer. Similarity value of 95% after alignment with Mola ramsayi (accession number accession AY940824) on GenBank, and the gaps of the nucleotide just 1%. The stranded sunfish identified using partial sequence mtDNA is the same species as the species Mola ramsayi.

Abstract

Forests are a source of foreign exchange that has been exploited on a large scale for timber. This exploitation causes a rapid reduction in forest area. Until now, the destruction of the forest environment is still happening, both by illegal logging and illegal mining. This study aims to determine the number of rare plant species in Alas Kedaton Tourism Forest, Tabanan, Bali, Indonesia; and the factors causing the rarity of these plant species. The population in this research is the plant species in Alas Kedaton Tourism Forest. Meanwhile, the social population is all people in the Alas Kedaton Tourism Forest area. The sampling method for plant species is the quadratic method was used to investigate the diversity and the number of rare plants. While for the social sampling was conducted by interviewing with purposive sampling method to the local community around the Alas Kedaton areas. Determination of endangered plant species was conducted by studying of available documents, in-depth interviewing, and seeking information from various existent sources. The collected data analyzed descriptively. The results of this study indicated there are 48 species of plants with 26 families, which are generally found in Alas Kedaton Tourism Forest. Of this number, 42 (87.5%) plant species are included in the rare category; (2) of the 42 species of rare plants in the Alas Kedaton Tourism Forest, there are 8 (19.04%) plant species that are included in the National rare category, 20 (47.62%) rare plant species in Bali, 10 ( 23.81%) rare plant species in Tabanan Regency, and 4 (9.52%) species included in the rare category at the District level (especially Marga District); and (3) factors causing the scarcity of plant species in Alas Kedaton Tourism Forest are (a) past environmental degradation, (b) reproductive problems of rare plants, (c) human intervention, (4) disturbance by animals, especially long tailed monkeys (Macaca fascicularis) and bats (Pteropus vampyrus).

Abstract

Remazol is a reactive dye that is widely used in the textile industry with functional groups that can be well covalently bonded to textile fibres, but difficult to decompose, carcinogenic, and harmful to the health and ecosystems. This study specifically aims to analyse the adsorption power of activated carbon on three types of Remazol dyes using batch experiment method as an effective way to reduce the concentration of these dyes in textile industry wastewater. Using activated carbon with the same treatment, Remazol Red dye had the best interaction and was adsorbed in the highest amount on the activated carbon surface (125.16 mg/g), followed by Remazol Blue (16.23 mg/g) and finally Remazol Black dye (11.07 mg/g). The three adsorption processes that occur are in accordance with the Langmuir adsorption isotherm model, with color removal percentage of 74.4 % (Remazol Red), 49.5 % (Remazol Blue), and 48.1 % (Remazol Black). These results are in accordance with the structural studies conducted on the three types of Remazol synthetic dyes, in which Remazol Black with the bulkiest structure has the weakest physical interaction with carbon atoms on the activated carbon surface thus absorbed in the least amount on the adsorbent surface.

Abstract

The forest in Wanagiri Village about 1.055 ha, and almost 250 ha of that forest managed as “village forest”. Village forest is the forest that is used by villagers, and in addition to being a natural reservoir area and maintaining water availability. This research aims to explored diversity and abundance soil insects that play a role in maintaining soil fertility. Surface insects were collected using the pitfall trap method, while infauna or ground insects were collected using the core method. The site of this research consists of 8 plots each site with random purposive sampling. The results showed that macrofauna species were higher than infauna. The diversity Index of soil insects is in the low category (0.355987).
