PENGUJIAN DAYA SIMPAN DAN VIABILITAS LIMA JENIS BIJI TUMBUHAN LANGKA: Parmentiera cereifera Seem., Santalum album L., Dillenia philippinensis Rolfe, Reutealis trisperma (Blanco) Airy Shaw dan Joannesia princeps Vell.
Get PDFFive endangered plant species (Parmentrera cereifera Seem., Santalum album L., Dillenia philipphinensis Rolfe, Reutealis trisperma (Blanco) Airy Shaw, Joannesia princeps Vell.) with recalcitrant seeds were studied to conserve them. The study aimed to determine the viability of the seeds with different storage treatments and their germination behavior. This study was conducted at the seed bank of Purwodadi Botanic Garden by storing seeds for three months, during which the seeds were sown to test their viability every month. Seed germination was done in the green houses at Purwodadi Botanic Garden with three replicates of three seeds to observe their growth. The germination percentage indicates the level of viability of the seeds after being stored for three months. Seeds of D. philippinensis are capable to germinate after being stored at room temperature for one month (55%) and cold temperature for two months (41.67%). Seeds of P. cereifera. can germinate after three months of storage at cold temperature (70%) or room temperature (56.67%). Seeds of S. album were able to survive in cold temperature and room temperature storage despite of low germination percentage (36.67% and 20%). Similar condition also accurs to J. princeps and R. trisperma, with the seeds of R. trisperma only survives after two months of storage. Storage period and storage temperature greatly affect seed viability of the five endangered plants species
Isolation and Screening for IAA production, Nitrogen Fixation, P-Solubilization and Cellulolytic Activity of Plant Growth-Promoting Rhizobacteria from Imperata cylindrica Grasslands
Get PDFIndigenous Plant Growth-Promoting Rhizobacteria (PGPR) are naturally occur for enhancement of soil fertility, producing plant growth hormones, nitrogen fixing, bio-composting and biodegradation of organic substances of soil without damaging the ecosystem. The objectives of this study was to isolate beneficial microbes using direct and enrichment methods on specific media, and screen these isolates for PGPR traits of Rhizobium-like strains, Azotobacter-like strains, Azospirillum-like strains and phosphate solubilizer-like strains isolated from four Imperata grasslands in Indonesia. About 208 isolates were isolated using direct and enrichment method from Cibinong (CSC); Central Kalimantan (Katingan) and Nusa Tenggara Timur (SV and RM) on specific media screened for IAA, phosphate solubilization, nitrogen fixation and cellulolytic activity. This study showed that enrichment method was effective for isolation of beneficial microbes. One hundred and seven isolates assayed exhibited ability to produce IAA about 200 µg/ml. One hundred sixty four isolates appeared solubilized of Ca-P complex and release orthophosphate. Ninety nine isolates showed ability to fix nitrogen and 24 isolates were able to degrade cellulose
Innovation and Integration: The ways for sustainable development in Agricultural System (Case study in Ciwidey Women Farmer Group Business Unit)
Get PDFThe great potential of agricultural sector in Indonesia has encouraged the development of various business utilizing agricultural products as raw materials. Involving about 240.000 micro, small, and medium enterprises (SMEs) developed in West Java, utilizing agricultural commodities as the main raw materials in their business activities. The type of business is very diverse in terms of organizational aspect. Moreover, some types of business that can be identified are family business, cooperative business, and empowering business. Each type business has its own different management influencing its performance. Technology adoption process and its value have to be integrated toward sustainable agricultural business . Accordingly, this study aims to identify the business types, strategies and technologies adopted by a farming business in developing the sustainable agricultural business system. This study was conducted at Business Unit of Ciwidey Women Farmer Group (WFG), which is able to develop business in group and produced massively in agricultural products. The number of business joining in Ciwidey WFG is about thirty unit business. The research method used direct observation in the field and semi-structured interviews conducted to WFG running business activity based on agricultural commodity. Data were analyzed descriptively with the explanation of the real conditions encountered in the field. The results of this study shows that the business type of Ciwidey WFG is cooperative business running by WFG and Farmer Group (FG). The upstream-downstream integration of business activities has been performed by the cooperation between Ciwidey WFG and FG. Innovation consists of three areas: The use of technology in the form of infiltration and methods in cultivating the organic concept, the formation of institutions and assistance in its management, and the implementation of collective marketing

amydrium humile Schott: TUMBUHAN MERAMBAT YANG UNIK DAN MENARIK DARI SUKU ARACEAE
No full textThe genus amydrium belong to the araceae family, consist of five species that is A. hainanense H.Li,Y.Shiao & Tseng,A. sinense(Engl.) H.Li,A. gumile Schott,A. medium(Zoll.&Moritzi) Nicolson and A. zippelianum (Schott)Nicolson. The last three species are found in Indonesia whereas the first two species occurs in Vientnam and Cina. Amydrium humile is found restrictlyin Sumatera and Malay Peninsula and consider rare in the wild due to habitat loss by human activities. Bearing no flowers on its climbing shoot A. humile is unique among other member of the genera. The species is collected from Regist 9B Seminung, Mount Lumbok Seminung Protected Forest, West Lampung Regency and cultivated in Bogor Botanic Garden.Genus amydrium milik keluarga araceae, terdiri dari lima spesies yaitu A. hainanense H.Li, Y.Shiao & Tseng, A. sinense (Engl.) H.Li, A. gumile Schott, A. sedang (Zoll. & Moritzi) Nicolson dan A. zippelianum (Schott) Nicolson. Tiga spesies terakhir ditemukan di Indonesia sedangkan dua spesies pertama terjadi di Vientnam dan Cina. Amydrium humile ditemukan terbatas di Sumatera dan Semenanjung Melayu dan dianggap langka di alam liar karena hilangnya habitat oleh aktivitas manusia. Tanpa bantalan bunga pada panjat tebing A. humile unik di antara anggota genera lainnya. Spesies ini dikumpulkan dari Regist 9B Seminung, Hutan Lindung Seminung Gunung Lumbok, Kabupaten Lampung Barat dan dibudidayakan di Kebun Raya Bogor
Application of Leaf Fertilizer to Seedling of Pyrenaria serrata Blume
Get PDFPyrenaria serrata Blume belongs to Theaceae family is a small tree up to 15 m distributed in rainforest from Sumatera, Java and Borneo islands on 200-2.000 m asl. The aim of this study was to determine the selection of leaf fertilizer to enhance P. serrata growth. This study was conducted in Cibodas Botanic Garden’s nursery for 6 months using Randomized Complete Block Design (RCBD). The design used three blocks, five treatment of leaf fertilizer types and three replications. The leaf fertilizer types were Growmore 10-15-10, Growmore Nutra+Zorb Ca, Rosasol N, Rosasol P and control. There were three parameters of seedling growth (height, root collar diameter and chlorophyll content) and four times observation. The results showed application of leaf fertilizer Rosasol N to enhance seedling height than other leaf fertilizer. The highest seedling height was 11.33 cm on the third block and the greatest of chlorophyll content was 28.66 SPAD on the first block. The selected leaf fertilizer of Growmore Nutra+Zorb Ca rate accelerates root collar diameter seedling growth significantly
Climbing Bamboos of Lesser Sunda Islands, Indonesia
Get PDFBamboos have been important for our livelihood i.e. as building materials, food, webbing, musical instrument, furniture, ornamental, etc. Bamboos usually have straight culms, but some bamboos have a climbing habit i.e. genus Dinochloa and only distributed in the west part of Indonesia. Lesser Sunda Islands (LSI) and Sulawesi seem to be the easternmost locality of the distribution of Dinochloa in Indonesia. No current information on Dinochloa from LSI has been made so far, thus a review on climbing bamboo from LSI is quite necessary. The objective of the study is updating information about climbing bamboos of LSI. This present study is expected to providebasic data about climbing bamboos in LSI. This research was conducted at the Herbarium Bogoriense by observing the climbing bamboo’s specimens from LSI. The results of the study showed, there are two species of climbing bamboos from LSI are recognized: Dinochloa kostermansiana and D. sepang. In addition, four specimens of Dinochloa cannot be further identified because of the incomplete information on the specimens
