Abstract

The research was conducted with the aim to identify species of arbuscular mycorrhizal fungi (AMF) associated with nedum [Pericopsismooniana (Thw.) Thw.]. Soil sampling was conducted in 6 locations of nedum habitat in South-east Sulawesi. The results showed that nedum associated with 15 species of AMF that belonging to 5 families and 9 genera, Acaulosporaceae (Acaulospora scrobiculata and A. delicata), Claroideoglomeraceae (Claroideoglomus etunicatum), Glomeraceae (Glomus aggregatum, G. boreale, G. canadense, G. halonatum,G. versiforme, Rhizophagus diaphanus, R. fasciculatus, Sclerocystis clavispora and Septoglomus constrictum), Gigasporaceae (Racocetragregaria and Scutellospora auriglobosa), Ambisporaceae (Ambispora appendicula). The four species of AMF were found on nedum, i.e Glomus boreale, G. canadense, G. halonatum and Racocetra gregaria which were a new record for mycological collection of Indonesia.

Abstract

Palms diversity, composition, and density in six selected sites of 15 rectangular plots of 100 x 20 m were successfully studied.The sites are in Kasepuhan Ciptagelar, which located in the Gunung Halimun Salak National Park in West Java.The sites are in the disturbed primary submontane forest at 800 to 1400 m altitude. Ethnobotanical observations made in some of the villages in Kasepuhan Ciptagelar proceeded through informal unending open interviews involving some traditional elders, prominent communities, and handicraftsmen. There is no species addition to the park from the Kasepuhan Cigelar. Three species of rattans(Calamus polysiachys, C. burcklanus, and Korthalsia laciniosa) are added to the park from Cibedug, Leuwijamang, Ciptarasa, and Cikidang. Young leaves of Daemonorops rubra are used for traditional Inner Baduy cloth. The use of C. javensis canes for bracelets and rings, and the infructescence of Plectocomia elongala for decoration are new findings.

Abstract

Pineapple (Ananas comosus L. Merr.), represents an important crop in Subang. Somaclonal variation is one of the problem to develop pineapple, especially Simadu variety. Probability to conduct Simadu progeny from the mother plant is very low (5%).Its caused by chimeric of the somatic cells that form meristem.In vitro culture is the alternative method to solve the problem by using the meristem cells from Simadu fruit as explant. Unfortunately, genetic diversity has been observed in many spesies during tissue culture.This phenomenon is usually termed somaclonal variation. Many studies on pineapple demonstrsted that some in vitro propagated materials differ from the source materials from which they are derived.To minimize genetic variability, the use of growth inhibitor such as paclobutazol and absisic acid hopefully would gave the important role in genetic stability. The aim of the research is to multiply Simadu pineapple by using tissue culture technic. In vitro shoot induce from crown of the Simadu fruit until get the sterile shoots. Combination of kinetin (0-5 ppm) with paclobutrazol ( 0-0.1 ppm) or ABA (0-1 ppm) was used in the multiplication stage. Result showed that there are no interaction between kinetin and paclobutrazol or ABA, but there is influence of the single factor. Kinetin increase leave number but decrease plant height and root number. Paclobutrazol increase shoot and leave number, but decrease plant height and root number. There is no influence of ABA to plant height, shoot and root number but decreased leaves number.

Abstract

The Study of soil arthropoda diversity in Upper Katingan River area was done in five different forest types i.e. 4 natural forest (With different vegetation) and one industrial tree plantation (HTI). The research site belongs to the PT Dwima Jaya Utama a consession timber in Central Kalimantan. Pitfall traps and soil litter samples were used to collect the arthropods and insect specimen. Twenty pitfall traps were set along 2 transect with 100 m length in each site and were operated forfour day. five soil-litter smaples of two litter were collected from each site. Soil-litter samples were examined in Berlese funnels for two weeks to sort the animals from debris. Identification was done based on the morphological appearce (morphospecies) and some taxon was determined up to order and/of family name. The results show that the most dominated taxon were collembola consit of 103 species from 13 families, and Coleoptera (33 species, 11 families). The most dominated taxon from Class Arachnid was Acarina (11 taxon) and Araneae (7 families). The Kilometer 33 (PUP) area has the highest species richness and abundance, whereas the Industrial Tree Plantation (HTI) has the lowest one of soil Arthropods. Based on the role of Arthropods on the forest floor, the most dominated group was decomposer and followed by predator and phytophagous. The unknown group mostly was consist of juveniles.

Abstract

This paper describes the ebony (Diospyros celebica Bakh.)site characteristics in Amaro Forest,Barru District, South Sulawesi including its secondary succession to create a favourable conditions for stand establishment. Association analysis shows that a wide variety of lowland species have been identified grows together with the ebony.Physical characteristics rather than chemical fertility of soils show a great value in supporting ebony stand growth.Poor stand with low natural regeneration of these remaining fragmented forests suggest the need to apply enrichment planting and improvement cutting to increase their productivity.

Abstract

Dua puluh sembilan isolat khamir diisolasi dari tanah Taman Nasional Gunung Halimun. Sumber isolat berasal dari batang pohon lapuk, akar lapuk yang diambil dari Gunung Botol, Cikaniki, dan Cipta Rasa untuk dipelajari aspek taksonominya. Berdasarkan atas karakter morfologi dan fisiologi, isolat-isolat tersebut digolongkan kepada kelompok ascomyceteous, basidiomyceteous dan imperfect khamir. Selanjutnya ketiga golongan tersebut dimasukkan ke dalam sepuluh kelompok (Kelompok 1 sampai X). Dari 29 isolat tersebut, 7 isolat dimasukkan ke dalam kelompok I diindentifikasi sebagai Debaryomyces hansenii, 6 dalam kelompok II sebagai Candida sp, 2 dalam kelompok III sebagai Pichia membranafaciens, 5 isolat dalam kelompok IV sebagai Candida galacta, 1 dalam kelompok V sebagai Candida sake, 4 dalam kelompok VI sebagai Cryptococcus humicolus, 1 dalam kelompok VII sebagai Rhodotorula minuta, 1 dalam kelompok VIII sebagai Candida sp, 1 dalam kelompok Candida sp, dan 1 dalam kelompok X dalam Candida sp. Macam sampel tampaknya tidak berpengaruh kepada keragaman jenis khamir seperti ditunjukkan oleh jenis yang sama diisolasi dari berbagai jenis sampel. Dari banyaknya jenis khamir yang diisolasi menunjukkan bahwa keragaman jenis khamir di Taman Nasional Gunung Halimun tergolong tinggi.

Abstract

One of bamboo forests which are located in a conservation area in Indonesia is Mount Baung Natural Tourism Park, East Java. Bambooforest is a uniqueness/distinctiveness in this area. Study of bamboo ecology in Mount Baung Natural Tourism Park was very important inconservation purposes. The objectives of the research were to assess the distribution pattern, association and abundance of bamboo species at Mount Baung Natural Tourism Park. A systematic quadrat method was used in this study. The distribution pattern of bamboo was calculated using Morisita Index by calculating the Chi-square formula while plant association was calculated using the contingency table. The results indicated that: (1) there were 11 plant species (bearing the Importance Value Index >10%) associated with bamboo, and showing a clumped distribution pattern, (2) bamboo supported the highest importance value, in which Bambusa blumeana was the dominant. The population structure of bamboo in this area showed pre-reproductive phase, indicating the dominance of young stage (D clump < 5m).

Abstract

Mutation by using Ethyl Methane Sulphonate (EMS) was carried out in the study of the enhancement of H2 and ethanol production in Bacillus pumilus.Target mutant was selected by using proton suicide method. Bacterial suspensions was spread into agar minimal U medium containing 13 or, 14, 15 and 16 u.1 of Ethyl Methane Sulphonate (EMS) and incubated at 37 C for 3, or 4 , or 5, or 6 hours.The method of proton suicide was applied by the addition of equimolar of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 75, 100, 125, 150, 175, 180, 185, 190, 195, 200 mM NaBr and NaBrO3.Triphenyl tetra chloride (TTC) was also added as indicator into agar plate in order to distinguish between wild type and mutants. Fermentation was carried out using glycerol complex medium.Hydrogen gas(H,) contain was determined by the replacement of NaCI solution in cylindrical glass and the ethanol was measured by gas chromatography. After mutation, several mutants were observed. In Mutant ( Asp8) which was obtained by treatment of 195 equimolar of NaBr and NaBrO,, production of ethanol and H2 were higher 10 fold and 1.13 fold, respectively compare to the wild type while acids production decreased. The data indicated that mutation might provoke metabolic alteration especially in acid production.
