ENKAPSULASI PROTOKORM UNTUK KONSERVASI JANGKA PENDEK Grammatophyllum speciosum Blume (ORCHIDACEAE)
Get PDFGrammatophyllum speciosum Blume is one of the threatened orchid species due to over exploitation and forest degradation, therefore this species needs to be conserved. One of the conservation efforts is to propagate through synthetic seed using sodium alginate as encapsulation matrix and calcium chloride as complexing solution. This research was conducted to obtain an optimal concentration of sodium alginate and calcium chloride for synthetic seeds forming and the best storage condition (temperature and storage period). Protocorm was used as the propagule of the synthetic seed. Sodium alginate 4% produced uniform and isodiametric shape, while calcium chloride 75 mM generated rigid and clear matrix wall to ensure the protection of propagule during storage. Extending storage period resulted in lower germination percentage. The encapsulated protocorms of K3-K6 which stored at 4oC up to 4 weeks still give the highest germination rate (93,33-100%). The synthetic seed of K2-K6 stored at 25oC was viable up to 16 weeks with the highest germination rate 93,33-100% and also has better regrowth than those having been stored at 4oC
STUDI ETNOBOTANI TUMBUHAN OBAT DAN UPACARA ADAT HINDU DI BALI
Get PDFDalam kehidupan sehari-hari, masyarakat Bali menggunakan tumbuhan untuk upacara adat dan sekaligus bahan obat tradisional. Meskipun sudah banyak penelitian yang mendokumentasikan tumbuhan obat dan upacara adat Bali, namun diduga masih banyak jenis tumbuhan yang belum dikenal oleh masyarakat luas dan belum mendapat perhatian serius. Penelitian ini bertujuan untuk mengetahui jenis-jenis tumbuhan obat dan deskripsi kegunaannya, serta mendokumentasikan bagian tumbuhan yang digunakan dalam upacara adat Hindu di Bali. Data etnobotani diperoleh dengan metode wawancara terhadap 20 responden. Pemilihan responden dilakukan secara purposive, yakni targeted respondents, yang dikombinasikan dengan teknik snowball. Hasil penelitian mendokumentasikan 57 jenis dari 52 marga dan 36 suku yang dimanfaatkan untuk keperluan obat sekaligus upacara adat. Jenis tumbuhan yang sering dimanfaatkan oleh masyarakat adalah rimpang-rimpangan dari suku Zingiberaceae. Terdapat 39 kelompok penyakit yang bisa diobati dengan menggunakan tumbuhan obat sekaligus upacara adat. Dewa yadnya merupakan upacara keagamaan yang paling banyak disebutkan responden. Lima jenis tumbuhan dengan use value tertinggi, yaitu Cordyline fruticosa, Plumeria rubra, Piper betle, Graptophyllum pictum, dan Morus alba. Perawakan tumbuhan didominasi oleh Kelompok herba, dan bagian tumbuhan yang paling banyak dimanfaatkan adalah daun. Hampir 70% tumbuhan yang didokumentasikan berasal dari kawasan Malesia, India, dan Indocina. Semua jenis tumbuhan tersebut dapat ditemukan di Kebun Raya “Eka Karya” Bali. Hal ini penting untuk menjaga keberlanjutan tumbuhan dan juga pengetahuan lokal yang terkandung didalamnya, sehingga generasi sekarang dan yang akan datang dapat mengetahui apa yang sudah dipraktekkan nenek moyang mereka
KIAMBANG KECIL (Pistia stratiotes L.): GULMA UNIK YANG KAYA MANFAAT
Get PDFPistia stratiotes L., is well known as water lettuce or 'kiambang kecil', belongs to theAraceae family. It is a monotypic genus. This free-floating plant aquatic distributed in tropical and sub-tropical country worldwide. It has been used in various purposes such as ornamental water plant, medicines (for the treatment of eczema, leprosy, ulcers, piles, stomach disorder, throat and mouth inflammation, a few to mention), bioindicator, bioremediation, purification and forage. On the otherhand, this species is quickly spread and form a dense mat that can cover an entire body of water thus can have negative impacts on native aquatic plants and fish. It is also host of mosquitoes.Pistia stratiotes L., is well known as water lettuce or 'kiambang kecil', belongs to theAraceae family. It is a monotypic genus.

THE EFFECT OF BAMBOO CLUMP MAINTENANCE ON NEW CULM PRODUCTION IN PENGLIPURAN BAMBOO FOREST BALI, INDONESIA
Get PDFThe use of bamboo in the daily lives of Balinese people requires sustainable access to good quality of raw materials. One way of doing that is by managing bamboo grooves. The aim of this study is to know the effect of bamboo groove maintenance on the productivity of bamboo culms in a bamboo forest at Penglipuran, Bali. The study was conducted by cutting >2years old culms and putting more soil around the bamboo groove. The difference in culms growth before and after treatments was calculated using analysis of variance that was followed by Tukey’s Test. The results showed that clump maintenance on bambu aya (Gigantochloa aya Widjaja & Astuti), bambu tali (Gigantochloa apus (Schult.) Kurz) and bambu papah (Gigantochloa sp.) generated an increase in the production of new culms. The number of culms of bambu aya increased by 150.5%, bambu tali 94.7% and bambu papah 150.6%
TERATAI JELI (Brasenia schreberi J.F. Gmel) DI PULAU SAMOSIR
Get PDFBrasenia schreberi J.F. Gmel or known also as water shield, was found in small natural pounds in Samosir Island during expedition in 2012. This species was known as “ate ateni aek” by the local people and has been used as source of traditional medicine. Although having wide spectrum of distribution in the world, this species is categorized as rare plant due to the existing of small population. Conservation of this species was suggested to be collected in a new developing area i.e. Samosir Botanic Gardens.Brasenia schreberi J.F.

Nepenthes gracilis Korth.: KANTONG SEMAR KECIL YANG MENARIK DAN MEKANISME DALAM MENJEBAK MANGSA
Get PDFNepenthes gracilis Korth. is one species of pitcher plant which has potential as a commercial ornamental plant. This species is widespread in Indonesia. Despite their small size, the pitchers are produced in enourmous numbers and mature plants can be very impressive. This species uses peristome, lower lidsurface and upper pitcher wall surface to trap the prey. N. gracilis allocates a higher proportion of its nectar production to the lower lid surface.Nepenthes gracilis Korth. is one species of pitcher plant which has potential as a commercial ornamental plant.

Belimbing Darah (Baccaurea angulata Merr.), Buah Keluarga Menteng Endemik Kalimantan dan Kerabatnya
Get PDFRed angle tampoi or scientific name Baccaurea angulata Merr. (Phyllantaceae) is an endemic plant of Borneo island. The other potential is not only as an exotic fruit but also contains antocyanin and antioxidant compounds which are high. The results also reveal the potential of red angle tampoi as a source of natural ingredients for the treatment of cancer and also has antimicrobial activity. Their close relatives besides menteng (Baccaurea racemosa) and tampoi (B. macrocarpa) also have B. dulcis (kupa), B. motleyana (rambai). The types of plants are generally dioceous so sometimes there should be a treewith its own male flowers and also there is a tree that flowering female itself. Grown in lowland (less than 800 meters above sea level) also in riparian areas of river or close to swamp areas. Propagation is mosteasily by seeds, cuttings and graft. Experiments with cuttings can grow leaves up to 3 months in the hood as well as graft within 3 months.Red angle tampoi or scientific name Baccaurea angulata Merr.

BIOGEOGRAFI, FENOLOGI, DAN PEMANFAATAN Reinwardtiodendron humile (Hassk.) Mabb. DI INDONESIA
No full textReinwardtiodendron humile (Hassk.) Mabb. is one of the members of the Meliaceae that has potential as a fruit plant. Information related to its distribution, phenology, and utilization is still limited. This study aims to determine the distribution of R. humile in Indonesia, phenology, and its utilization. The research was conducted using methods of direct observation in the field, herbarium, and relevant references, then the collected data was interpreted descriptively. In Indonesia, the species has a wide distribution area, from Sumatra, Java, Kalimantan to Sulawesi. The fruiting and flowering periods occur throughout the year, depending on the location of the growth. Black ants and weaver ants are thought of as visitor animals, as well as pollinators and the seeds dispersal is predicted done by squirrels. Uses of R. humile is done by local people in Sungai Tapa, Jambi as fresh fruit and firewood. The fruit flesh has a sweet taste, so it has the potential to be developed as fresh fruit and processed fruit
