Abstract

Citra Pleaides merupakan aset penting untuk memperoleh data dan informasi tentang struktur vegetasi di hutan yang sulit untuk diukur langsung karena wilayah yang tidak dapat diakses dan memiliki cakupan luas. Dacrycarpus imbricatus (Blume) de Laub. merupakan salah satu tanaman khas di Bukit Tapak yang memiliki nilai konservasi dan nilai ekonomi. Penelitian ini bertujuan untuk mengetahui persebaran D. imbricatus menggunakan data citra satelit Pleaides yang memiliki resolusi spasial tinggi. Penelitian dilakukan dengan interpretasi visual pada citra satelit Pleaides tahun 2014 dan data spasial elevasi. Akurasi citra Pleaides dalam identifikasi tutupan D. imbricatus mencapai 96,83% dan ketelitian total pemetaan mencapai 93,38% dengan koefisien kappa 88,64%. Persebaran D. imbricatus di Bukit Tapak memiliki range habitat aktual lebih sempit dibandingkan dengan range potensialnya yakni pada elevasi 1.321-1.800 mdpl dengan persentase tutupan 89,52% dari total tutupannya. Lereng Bukit Tapak dengan kemiringan 25,1-55% memiliki lingkup tutupan D. imbricatus sebesar 79,29% dari total tutupannya dan sisanya pada lereng>25%. Informasi tersebut penting terkait dengan kelestarian dan usaha konservasi salah satu jenis tumbuhan berbiji terbuka ini di Bukit Tapak.Kata kunci: akurasi; interpretasi; kanopi; konservasi; pleaides Usage of Satellite Imagery to Determine Distribution of Dacrycarpus imbricatus (Blume) De Laub. on The Tapak Hill, Batukahu Natural Reserve BaliAbstractPleaides image is an important asset to obtain data and information with regard to the structure of the vegetation in the forest that are difficult to measure directly as the area is inaccessible and has a large coverage. Dacrycarpus imbricatus (Blume) de Laub. is the one of typical plants on the Tapak Hill which has the conservation and economic values. This study aimed to determine the location and distribution of D. imbricatus using Pleaides satellite image that had a high spatial resolution. The determination of site characteristics was conducted by visual interpretation of high resolution satellite imagery Pleiades 2014 and elevation spatial data. Pleaides accuracy in the identification cover of D. imbricatus reached 96.83% and total accuracy mapping reached 93.38% with kappa coefficient of 88.64%. The distribution of D. imbricatus in Tapak Hill showed actual habitat range narrower than of its potential, which was distributed on the elevation of 1,321 ? 1,800 m asl with a percentage of 89,52% from its total cover. About 79.29% of the coverage laid on the slope of 25.1 to 55%, whereas the rest on the slope of >25%. This information is important related to sustainability and conservation efforts for this gymnosperm plant in Tapak Hill.

Abstract

Spheranthus africanus is a minor weed of rice, which can be utilized for various purposes. It can be used for phytoremediation of soil contaminated with Pb and also reported to have anti-bacterial activity to be used as natural pesticides. However, because of its minority status little is known about this species in its natural habitat. This study was aimed to understanding the relationship between S. africanus with other weed species in a fallowed paddy field in Tabanan District, Bali, Indonesia. Vegetation analysis by quarter method was done in the rice field, where the species had occurred, in 2011 and 2012. Determination of association type between S. africanus with other weed was conducted by using 2x2 contingency table to calculate χ2, association coefficient (AC) and Ochiai index (OI). The result shows that the Shannon diversity index in this same area for the two consecutive years were 2.06 and 2.48 with species richness of 22 and 27 respectively. Calculation of Summed Dominance Ratio (SDR) showed that the species composition was not evenly distributed, in other words some species dominated others. In terms of association, although S. africanus mainly has no association with most of the weed species in the field, it prominently has positive association with Lindernia ciliata, and Digitaria ciliaris, with no significant negative association. Keywords: diversity, species association, Spheranthus africanus

Abstract

Dicksonia blumei (Paku Kidang) termasuk dalam spesies prioritas konservasi Indonesia kategori B. Studi ekologi habitat alaminya di kawasan hutan Bukit Tapak, Bedugul Bali dilakukan dengan metode purposive sampling. Plot dapat dibuat sebanyak 3 (tiga) buah dengan ukuran 20 x 20 m untuk jenis tumbuhan pohon dan 2 x 2 m untuk jenis tumbuhan bawah. Berdasarkan hasil pengamatan Dicksonia blumei (Paku Kidang) pada habitat alaminya di kawasan hutan Bukit Tapak. Jenis paku ini tumbuh pada kondisi lingkungan fisik dengan kisaran ketinggian tempat antara 1.754–1.794 m dpl., kemiringan tanah berkisar antara 7–10%, pH tanah 6,4–7, kelembaban tanah 50–75%, temperatur 20,5–22,3°C, kelembaban udara 83,2–87,5% dan intensitas cahaya 618–10.030 Lux. Karakteristik komponen lingkungan biotiknya ditentukan berdasar Indek Nilai Penting (INP). Lima jenis tumbuhan pohon dengan INP tertinggi adalah Cyathea latebrosa (INP 98,7) kemudian diikuti oleh Saurauia bracteosa (INP 51,9), Astronia spectabilis (INP 42,7), Dicksonia blumei (INP 39,6) dan Homalantus giganteus (INP 35,3). Karakteristik jenis tumbuhan bawah untuk lima jenis tertinggi diduduki oleh Pillea sp. (INP 61,91), kemudian diikuti oleh Selaginella sp. (INP 40,6), Athyrium asperum (INP 27,5), Pteris tripartita (INP 18,3) dan Rubus sp. (INP 15,0). Kebersamaan tumbuhnya D. blumei dengan Cyathea latebrosa, tampaknya terkait dengan peran batangnya sebagai substrat spora D. blumei pada tahap perkecambahan dan pertumbuhan selanjutnya. Pada fase gametofit dan sporofit muda D. blumei tumbuh secara epifit pada batang Cyathea latebrosa setinggi 0,5–1,5 m dari permukaan tanah. Seiring dengan pertumbuhan akarnya yang berlahan-lahan mencari tanah, kemudian sporofit dewasa D. blumei akan tumbuh secara teresterial (hemi–epifit).

Abstract

Along with society awareness of the importance of healthy life, demand of agricultural products which are pesticide residues free has been increasing. Recently, efforts to control plant pests and diseases by farmers have been relied on synthetic pesticides. Utilization of this kinds of pesticides results in various diseases such as cancer, fetal defects, infertility, liver diseases, and so on.  One of the alternatives which can be chosen to minimize those negative effects is using organic pesticides. Its ingredients are organic compounds which easily degraded, do not pollute the environment and relative safe for humans and livestock because its residues are degradable. Indonesia is one of countries with biggest biodiversity in the world, so it has great opportunities to produce organic pesticides. Bali Botanic Garden (BBG) is a government institution which plays role to conserve various kinds of plants from their natural habitats, especially the threatened species. This activity was aimed at knowing how many plant collections in BBG which have potency as organic pesticides and their specific functions whether as fungicides, insecticides, bactericides, rodenticides, nematicides, molluscicides, or fish poisons. The results show that there were 23 plants which have potency as organic pesticides. From that group, 22 kinds act as insecticides, 7 as fungicides, 5 as nematicides, 3 as molluscicides, rodenticides, fish poisons (pissicides), and bactericides respectively.Keywords: organic pesticides, Bali Botanic Garden, plant collections Keywords: organic pesticides, Bali Botanic Garden, plant collections

Abstract

Indonesia is well known as one of the countries with high biodiversity in the world, including its orchids. It is expected that there are 6,000 kinds of orchids which grow wildly in forest regions around the world. Along with accelerated forest destructions in Indonesia, due to land conversions or natural disasters, the existence of orchids in their natural habitats is threatened. It is likely that some of these richness could be lost before they can be conserved and known of their functions. Regions of Tambora mountain in Sumbawa island have biodiversity that had not been revealed. Therefore, taking inventory of flora in that region is very crucial to be done as soon as possible. This activity was aimed at saving biodiversity especially rare and endemic orchids there, and also quantitatively knowing richness and frequency of orchids species which are found. From the research, it is known that there were 22 orchids species, from which only one is terrestrial and the rests are epiphytes. In terms of richness, there were some orchids which were common and also rare. Keywords: orchids, Tambora Mountain, conservation, exploration
