The Induction of Root Nodule and Increasing of Nitrogen Content of Common Bean (Phaseolus vulgaris L.) by Using Rhizobium Plus Fertilizer
Common bean (Phaseolus vulgaris L.) is consumed by many people in Indonesia. Naturally, this plant has a mutualism symbiosis with Rhizobium to build root nodules. This symbiosis gives nutrition supply for plant and supports plant growth. The aim of this research was to find the best concentration of Rhizobium plus fertilizer to induce root nodule’s number and to increase nitrogen content of common bean. This study was conducted in Green House of Biology Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. This was an experimental study using a Completely Randomized Design with six treatments and three replications. The data was analyzed using Analysis of Variance (ANOVA). Measurement of nitrogen content of bean’s leaf was using Kjeldahl method. The study result revealed that Rhizobium plus fertilizer increased the root nodule’s number with the best concentration was 1.25 g. This research also revealed that Rhizobium plus fertilizer showed significant effect on the nitrogen content of bean’s leaf with the best concentration was 1.5 g.
 
PEMANFAATAN NUNU PISANG (Ficus magnoliifolia Blume) OLEH MASYARAKAT SUKU MOMA DI SULAWESI TENGAH
Moma Tribe community in Central Sulawesi utilize nunu pisang (Ficus magnoliifolia Blume) to meet in their daily needs for food, medicine and cloth. This study aimed to identify the utilization and conservation of nunu pisang at Moma Tribe community. The data were obtained through interviews and questionnaires which were analized with the perception of the frequency distribution and chi square. The results showed that respondents of Moma Tribe who had traditional knowledge on the process and utilization of nunu pisang as cloth material was 50%, as a functional food or a flavor enhancer 6% and as medicine 6%. The knowledge on utilization of nunu pisang was mostly possessed by the age classes of 55-69 years, and there was no differences between men and women because both of them were involved in the utilization
A RARE AND ENDEMIC SPECIES OF Homalomena bellula Schott (ARACEAE) IN JAVA: REDISCOVERY AND CONSERVATION
Homalomena bellula Schott belongs to the Araceae family. It is an endemic and rare species (vulnerable, according to IUCN criteria) of Java. In addition, H. bellula has a unique shoot architecture which differs from that of other Javanese Homalomena. The shoot architecture of H. bellula resembles that of ginger’s, closely conforming to Tomlinson’s model. Schott described this Javan species in his Protologue published in 1863. Since then, the species had not again been encountered in the field, until its rediscovery in recent years. The aims of this study were to provide an account of the occurrence of H. bellula in its natural habitat, to describe its shoot organisation, and to report on efforts undertaken to conserve the species. Field observations and studies based on herbarium specimens and living specimens were used in the research. Based on type specimen data, the locality of the original specimen was cited as Mount Halimun in West Java. Several field investigations in Java found that H. bellula occurs in Pancuran Tujuh, on the slope of Mount Slamet, Baturraden, Central Java. An ex situ conservation effort is necessary to sustain this species because the population within its natural habitat is alarming
ANALISIS VEGETASI DAN ALTERNATIF ZONASI PEMANFAATAN LAHAN DI KEBUN RAYA SAMPIT, KALIMANTAN TENGAH
Recording the existing diversity of an area is necessary to be done before the area is developed into a botanic garden. This study aims to determine the composition, structure and community type of Sampit Botanic Gardens to serve as the basis for determining its land use zoning and collection themes. A vegetation analysis was conducted using plot method that was placed in five locations (each 500 m2). All of the trees, sapling and ground vegetation were enumerated. A total of 40 families, 64 genera and 85 species were found within total plot of 2500 m2. The results shows that there are 30 species of trees, 36 species of sapling, and 43 species of ground vegetation. The highest number of trees is found in plot Lb-C (19 species), but plot Lb-D has the highest diversity and evenness indices. The three plots in dryland are dominated by Imperata cylindrica (Lk- A), Acacia mangium (Lk-B) and Melaleuca leucadendra (Lk-E), while the two plots in the wetlands are dominated by Tetramerista glabra (Lb-C) and Palaquium calophyllum (Lb-D). The highest tree density in plot Lb-C (800 trees/ha), while the highest basal area in Lb-D (24.1 m²/ha). Base on NMDS ordination, the vegetation tends to form three communities, namely: 1) Imperata cylindrica - Dicranopteris linearis, 2) Melaleuca leucadendra - Acacia mangium, and 3) Palaquium calophyllum - Tetramerista glabra. Community of P. calophyllum - T. glabra should be maintained as in situ conservation areas. I. cylindrica - D. linearis community can be usedfor physical buildings, thematic parks, nursery and plants development. The collection zone should be placed at the M. leucadendra - A. mangium community, and in part on the P. calophyllum - T. glabra and I. cylindrica - D. linearis communities. Collection theme for Sampit Botanic Garden suggested is ex situ conservation for heath forest
ALTERNATIF LOKASI PENGEMBANGAN KEBUN RAYA DAN EKSPLORASI TUMBUHAN HUTAN MONSUN MERANGGAS BERBASIS PETA DISTRIBUSI TIPE HUTAN DI NUSA TENGGARA
A study of alternative locality of botanic garden developments and flora explorations in deciduous monsoon forests based on forest type distribution in Nusa Tenggara has been carried out. The forest type distribution was allegedly obtained through overlay process of vegetation formation and satellite image of forest covering using software Arc-GIS versi 10.3. in Nusa Tenggara. A total of five forest types succeeded in mapping of Nusa Tenggara forests namely, evergreen rain forests (1008.77 km2), semi-evergreen rain forests (2944.98 km2), moist deciduous forests (6120.36 km2), dry deciduous forests (7955.18 km2) and thorn forests (93.07 km2). The existing forests in Nusa Tenggara reached 18122.36 km2 or 27.30%, in total. All of regencies/cities in Nusa Tenggara seemed appropriate to botanic garden developments, themed deciduous monsoon forests, based on habitat compatibility. At least each botanic garden developments covering an area of 10 ha consist of 500 species of potential trees collection. There are 58 coordinate point sites in which scattered in13 sub types of deciduous monsoon forests as a guide for exploration sites are recommended. It is about 487 species (trees, shrubs and woody plants) are potentially collected. Several large families are found such as Leguminosae (49 species), Malvaceae (28 species), Meliaceae (26 species), Moraceae (25 species), Rubiaceae and Rutaceae (23 species on each). A total of 59 species are listed in the IUCN red list, particularly four endangered species and 12 vulnerable species as put priority when conducting plant explorations
PENGARUH INTENSITAS NAUNGAN DAN PEMBERIAN PUPUK ANORGANIK TERHADAP PERTUMBUHAN SEMAI Hopea bancana (Boerl.) Slooten
Hopea bancana (Boerl.) Slooten is an important species of timber-producing trees. This species is endemic to Indonesia and is categorized as threatened plant (critical: Critically Endangered) based on the IUCN Redlist of Threatened Species 1998. Research and development on its silviculture aspects is very important as an effort to support the recovery of species and enrichment of the population in nature. This study aims to determine the effect of shade intensity and application of inorganic fertilizer (NPK) on Hopea bancana's survival and seedling growth. The study was conducted with factorial complete randomized design consisting of 2 factors, namely: shade factor with 2 levels (50% and 75%) and inorganic fertilizer with 4 levels (0 gr, 3, gr, 4 gr, and 5 gr), so that 8 combinations of treatments were obtained. The survival rate was analyzed descriptively. Growth variables which included growth in height, number of leaves, leaf length, and root length were analyzed by analysis of variance (ANOVA). The results showed that the shade intensity of 50% gave better results in the survival rate of the seedlings. Shade intensities and inorganic fertilizer factors showed very significant differences in plant growth and root length. The best results of growth parameters of plant height, leaf number, and leaf length were indicated by N350 treatment (NPK fertilizer 3 gr, 50% shade intensity), while root length was indicated by N050 (NPK fertilizer 0 gr, shade intensity 50%). Treatment of NPK 3 gr at 50% shade intensity tends to show the best results in the character of seedling growth
