Abstract

Ethnobotanical research on the utilization of plant species in Tau Lumbis village of North Kalimantan by Tagol and Akolod Dayaks ethnics has been conducted.Seventy seven species of plants have been recorded to be utilized by the people for various purposes from medicinal to magical-supranatural. Some literature reviews suggested that there was correlation of traditional knowledge and modern science in plant utilization by these ethnics.

Abstract

Study on diversity and abundance of Orthoptera (insect) was conducted at a tropical mountainous rainforest of Java, Mounts Kendeng and Botol, Gunung Halimun National Park, West Java, Indonesia, from January to March 2002. Total Orthoptera captured was 414 individuals,consist of 25 species and 9 families. Shannon Diversity Index and evenness were higher at Mount of Kendeng (2.44 and 0.81) rather than Mount Botol (1.80 and 0.66).Similarity Index of Jaccard and Sorenson of both localities were similar (0.40 and 0.32).Relative abundant of each family and species will be compared between the two locations also.

Abstract

An increasing of population, land conversion, and the behaviour changes in many crops due to global warming could produce a significant negative effect to food security in many countries, including Indonesia. In order to maintain the availability of food, we should find out alternative foods based on corp comodities that can adapt to future agricultural land conditions. One species to be promoted for that purpose is Tacca leontopetaloides (taka). This study was aimed to determine growth characteristics variations of taka in Java and its surrounding small islands through exploration and interview methods. Results indicated that there were two morphological variations of taka based on the canopy colour, namely green and purple. Taka found growing in coastal areas up to100 m above sea level. The light intensity and soil type greatly affected their growth. These plants lived either solitary or in a groups, grow well on sandy soil to clay, under the shade and open areas. Species around taka allegedly contributed in determining taka growth and production. Taka tuber can be an alternative carbohydrate source for supporting food self-sufficiency in coastal communities.

Abstract

Gold mining activities have recently increased in many areas. Contamination with heavy metals, mainly mercury due to illegal mine (PETI) have been in concern to residents around the area. One approach to remediate risks from some toxic metal pollutants is phytoextraction using hyperaccumulator plants. These remarkable plant species accumulate appreciable high concentrations of metals than do normal plants when the normal plants suffers yield reduction from metal phytotoxicity. Possible solution of using indigenous plants for phytoremediation has been studied. Performance of four selected plant species i.e Paspalum conjugatum, Centrosema pubescens, Commelina nudiflora and Mikania cordata were examined. In this study the plants were grown in PETI waste media contaminated with 25.733 ppm mercury (Hg), added with mercury (II) chloride (HgCl2) with different levels of concentrations i.e. 0 ppm Hg (HO), 10 ppm Hg (H10) and 20 ppm Hg (H20). To increase mercury uptake from the media, chelating agent, ammonium thiosulfat (NH4),S2O, was applied with concentration of 0 ppm (KO) dan 50 ppm (50). Plants biomass and mercury accumulation in plant shoots and roots were assessed at one and two months after treatments. The results showed that all of the plant species under study were highly tolerant to Hg. It was indicated by plant normal performances and high biomass production even in the highest level of Hg concentration and high Hg accumulation in the plant shoot and roots that reached 41.860 ppm in the shoot of P. conjugatum (H10 with chelate), 40.054 ppm in the shoot of C. pubescens (H20 no chelate),41.089 ppm in the shoot of C. nudiflora (H10 no chelate) and 42.610 ppm in the shoot of M. cordata (H10 no chelate). At the highest concentration levels of Hg under study there was no effects of toxicity on the plants, indicated by normal plant growth and high biomass production. Higher accumulation of Hg were found in the plants treated with higher level of Hg concentrations.

Berita Biologi 3(6): 268 -272.Intercropping system to reduce number of potential insect pests. However, the result will be vary depend on the appropriate component of the selected crops.The experiments using toniatoes as an intercrop of pigeonpeas was carried out at the HKTI (Himpunan Karya Tani Indonesia) garden at Tajur Bogor.The number of insect species as well as diversity in the intercropped pigeonpeas were compared with that in the pure stand of the same crops. The result indicated that number of insect species visited in the intercropped pigeonpeas was greater than in its pure culture.The number of insect species in the intercropped and pure pigeon peas increased with the increase of its developmental stages.The index diversity in the intercropped pigeonpeas were higher than that in its culture.

Abstract

tRNA " UAA (trnL) intron have been widely utilised for phylogenetic reconstruction in angiosperm families. Two main helical elements of secondary structure of trnL intron (stem loop regions P6 and P8) contained the most variable sequences across taxa.Detailed examination on the insertion-deletion events in trnL intron sequences of 110 species of Dipterocarpaceae has identified 4 stem loop structures within both loops.The first stemJoqp was found in P6 loop and three other were discovered in P8 loop.These structures featuring characteristic for genericJinfra-generic level depended upon which taxonomic classifications are foJJowed.One of these structures formed a large loop of 72 nucleotides and was a unique major stem loop in Dipterocarps family whose loop was the major structural mutation of trnL intron in this family.

Abstract

Lactobacillus plantarum S34 dilaporkan mempunyai aktivitas antibakteri yang terkait dengan produksi bakteriosin. Bagian dari gen yang menyandikan salah satu lokus bakteriosin yang diproduksi oleh L. plantarum S34, disebut dengan plantarisin W (plnW), diamplifikasi dari plasmid dan dikloning menggunakan sistem vektor pGEM®-T Easy ke dalam Escherichia coli DH5?. Sekuens nukleotida plnW (± 405 pb) diidentifikasi sebagai protein integral membran. Lebih lanjut, plnW diekspresikan secara heterologus sebagai fusi protein dengan His(6)-tag tioredoksin menggunakan vektor ekspresi pET-32a(+) ke dalam E. coli BL21 (DE3) pLysS. Protein fusi rekombinan plnW terdapat dalam sitoplasma sel, tetapi selain fraksi terlarut terdapat juga fraksi tidak terlarut berupa badan inklusi. Purifikasi parsial dilakukan menggunakan kromatografi afinitas ligan Co2+ untuk fraksi terlarut dan metode elektroelusi gel poliakrilamid untuk fraksi tidak terlarut. Massa molekul berukuran kurang lebih 33 kDa terdeteksi berdasarkan pemisahan SDS-PAGE dan dikonfirmasi dengan Western blot sebagai protein fusi rekombinan plnW. Protein yang sudah terpurifikasi bermanfaat untuk mengetahui kaitan antara struktur dan fungsi bakteriosin.

Abstract

Cendana {Santalum album L.)merupakan tumbuhan yang termasuk dalam kelompok suku Santalaceae. Sebagai anggota kelompok tumbuhan parasit, pada fase pertumbuhannya cendana memerlukan interaksi dengan tumbuhan lain yang berfungsi sebagai inang, melalui alat-alat kontak yang disebut haustorium. Sistem perakaran cendana, di mana padanya haustoria berkembang, lebih didominasi oleh pertumbuhan horizontal. Jenis tanaman inangnya tidak spesifik, sehingga pemilihan jenis tanaman inang untuk cendana dapat disesuaikan dengan model-model yang akan dikembangkan yaitu model agroforestri atau konservasi.

Abstract

Nepenthes spp. (pitcher plants) are carnivorous plants, because it can trapping and digesting insects and other small animals in their pitcher as their food. In 1996, there were 80 species noted in the world. Nowadays, the number has increased up to 139 species and 68 species(48.9%) of whom live and grow on various islands in Indonesia, such as Sumatra (34 species), Kalimantan (22 species), Java (3 species), Sulawesi (11 species), Maluku (3 species) and Papua (11 species). Herbarium Bogoriense-Research Center for Biology-The Indonesian Institute of Sciences (LIPI), as the central storage plant specimens in Indonesia, currently holds 2135 sheets of 72 species of Nepenthes are collected from various islands in Indonesia and from other countries. This paper will review the current number of Nepenthes and its distribution in various islands in Indonesia.
