Dyera lowii is an endemic and vulnerable tree species of commercial value as chewing gum found inpeat swamp forests, scatteredly distributed in Sumatra, Kalimantan, and Peninsular Malaysia. Their existenceis now under severe threat due to habitat conversion. This study is aimed to assess genetic diversity withinfour natural populations (Hampangen, Parahangan, Sebangau, Selat Nusa ) and one plantation in CentralKalimantan based on allozyme variation. Electrophoresis procedures were conducted with an isoelectricfocusing polyacrylamide slab gel system. The result showed high genetic diversity (HE=0.52) and gene fl ow(3.402) seemed to be effective. A total of 14 alleles were found among all the analysed population. Meannumber of alleles per locus (Aa) was 3.206, and the effective number of alleles per locus (Ae) was 2.21. Geneticdifferentiation between populations (FST) was signifi cant at the moderately level (0.0685). Most allozymevariation was found within population (93.2%). Special attention is essential to conserve a private allele ofGot-1-e (9%) at Selat Nusa population. Sebangau population missed the alleles of Est-2-b and Got-1-a, as foundin other populations. Selat Nusa population is expected to enhance the effective management for geneticresources conservation of this vulnerable species in the future.

Advances in technology have encouraged the growth of a variety of biodiversity processing methods. These conditions encourage efforts to use natural resources more broadly. Ethnobotany can be used to document the local knowledge of the plants and their utilization. This study is aimed to describe the various forms of bamboo utilization by Sangirese. The method used was survey with purposive sampling. The data were analyzed descriptively based on exploration results and interviews with the people. The results showed there were 11 species of bamboo that are directly related to the life of local community in Sangirese, consisting of seven species of Bambusa, three species of Schizostachyum, and each one species of Dendrocalamus and Gigantochloa. Local community use bamboo for a variety of daily necessities; as building materials, handicraft, furniture, ceremonies, musical instruments, transportation, medicine, ornamental plants, as well as food. These exploration results are expected to complement the data of bamboo ethnobotany in Indonesia. Applicatively, this research is expected to be a reference in the national strategy of bamboo germplasm resource conservation.

Dioscorea spp. were cultivated as alternative food in the garden and yard on dry season, and it’s planted by peoples in the villages. The objectives of the research are to identify the species, the tuber use, and the local wisdom to support the conservation of Dioscorea around Wonosadi forest. Samples and data collection was conducted in 15 villages around Wonosadi forest. Interview survey was done on peoples who are cultivate yam species (Dioscorea spp.) in their garden. Research were emphasized to tuber characteristic, traditional uses, and local wisdom to supporting yam conservation. Data was analyzed descriptively to illustrate the kind of local usage and local wisdom of connect with Dioscorea spp. The results showed that there were found species of gembili (D. esculenta (Lour.) Burk.), uwi (D. alata L.), and gadung (D. hispida dennst.) as cultivated plants, and tomboreso (D. pentaphylla L.), gembolo (D. bulbifera L.), and jebubuk (D. numularia Lamk.) as wild species in the forest. Tuber is raw material for many kind of food based on carbohydrate content. Gadung were used as fickle food with high diversification and insecticide for rice and corn. Peoples more consume gembili and uwi than gembolo and others species as rice substitute at dry season. The local wisdom were indicated that peoples still consume gembili and uwi as rice substitute, while tuber also used as sesaji in traditional concept jajan pasar or tukon pasar, and tuber of uwi was used as diet for diabetes complaint, and row material of uwi ungu tuber was used effectively for diarrhea complaint in the villages.

ABSTRAK Perkembangan buah kacang tanah hanya terjadi di dalam tanah. Organ yang membawa buah masuk ke dalam tanah adalah ginofor yang terbentuk setelah fertilisasi terjadi. Apabila buah tidak masuk ke dalam tanah maka, embrio, biji dan buah kacang tanah tidak dapat berkembang. Setiap tahap dari perkembangan tumbuhan dipengaruhi oleh protein spesifik. Penelitian ini bertujuan untuk mengetahui profil protein pada setiap tahap perkembangan buah kacang tanah. Analisis profil protein dilakukan pada beberapa tahap perkembangan buah yaitu pada umur 0, 4, 6, 15, 18 dan 23 hari setelah anthesis (hsa), baik pada buah yang berkembang (masuk ke dalam tanah) maupun tidak berkembang (tidak masuk ke dalam tanah), serta akar, batang dan daun menggunakan metode SDS-PAGE (sodium dodecyl sulphate-polyacrylamide gel electrophoresis). Profil protein pada buah berbeda dengan profil protein pada akar, batang dan daun. Protein dengan berat molekul 124 kDa kemungkinan berperan dalam mengontrol perkembangan buah kacang tanah. Kata kunci: Arachis hypogaea, profil protein, perkembangan buah

Species of Bambusa had widespread in Celebes, especially for Bambusa striata and Bambusa vulgaris. As an effect of the lacking of flowering, species identification mainly depends on vegetative features, and leaf epidermal micromorphology has proven to be useful in bamboo taxonomy. The objective of this research was to describe the classification of Bambusa from Celebes based on the micromorphological characters of leaf epidermis. The specimens were collected from wild population. The samples of leaf were collected from five member of Bambusa i.e.: Bambusa blumeana, Bambusa maculata, B. striata, B. vulgaris and Bambusa sp. Micromorphological characters were identified using Scanning Electron Microscopy (SEM). Leaf epidermis characters separated B. blumeana from other species of Bambusa. Furthermore, B. striata were closely related to B. maculata in variation of bulliform cells. As an invention, we release peltate hair as a new type of trichome in Bambusa. The presence of various prickles, trichomes and bulliform cells may be especially useful in delimiting species.
