Abstract

Pendem village in Jembrana regency is one of the banana plantation in Bali. Now a days banana plants were attack  by  bacterial wilt disease   with the symptoms of wilting plants, brown spots on the vessel banana stems and fruit to rot and dry. Control of use of chemical fertilizers can cause bad impact on environment and also can not control the disease. Streptomyces bacteria are bacteria that are capable of producing enzymes and antibiotics that can be used as biocontrol agents of several diseases in plants. The purpose of this research is to isolate and identify the bacteria  Streptomyces  from  rhizosphere  of  banana  plants  without  symptoms  in  the  village Pendem Jembrana regency. The method of isolation of Streptomyces using Platting method, Streptomyces isolated from soil rhizosphere of banana plants without symptoms or health plant. Soil was taken by digging near rooting bananas plant about 15 cm from the ground and and the sample was growth on media Humic Vitamin Agar (HVA) and Yeast Extract Malt Agar (ISP4).

Abstract

Indonesia has a vast forest area. The extent of Indonesia's forests is one of the natural resources are prone to damage due to human interests in meeting their needs. One of the damage that often occurs when current is forest fires. Forest destruction accounts for 20-25% of global CO2 emissions that contribute to climate change or global warming. Unspoiled forest with a diversity of plant species are long-lived and litter is a place to store a lot of carbon stocks (C) the highest. The aim of this study was to determine the diversity of plants and the amount of carbon stock above ground level in the forests of the Bukit Barisan of Padang, West Sumatra. Tree biomass was calculated on a plot of 20x20 m, 10x10 m pole, stake 5x5 m, for counting down plant biomass and litter on the plot with a size of 2x2 m (National Standardization Agency, 2011). Biomass calculated by the Ketterings et al. formula (2001). In Bukit Barisan Forest Area, West Sumatra, derived carbon content was 16.029,70 ton/ha. Diversity type was highest at tree level on Station 1, classified as very high diversty with diversity index (H’) 3.10.

Abstract

Recently, climate change is the one of most important environmental issue. Climate variability can be recorded by tree growing through the growth ring. Growth ring formed by cambial activity were examined in wood anatomy. In Sumatra, there are three ecotypes Pinus merkusii, namely ecotypes Kerinci, Tapanuli, and Aceh which can be distinguished morphologically. This study aims to knowing the wood anatomical characteristics of the three ecotypes and determine the potential as climate indicator. This study was conducted in October 2014 until June 2015. Sample of Kerinci ecotype was collected in Kerinci Seblat National Park, Tapanuli ecotype in Dolok Sibualbuali Natural Reserve and Aceh ecotype in Gunung Leuser National Park on a height of 130 cm using increment borer and cut on the main stem 5×5 cm for anatomical sample. Results from this study indicate that ecotype Kerinci and Tapanuli showed earlywood and latewood boundary exposing the clear growth ring, whereas in Aceh ecotype unclear. Tapanuli ecotype have the thickest tracheid diameter than ecotype Kerinci and Aceh. Ecotypes of Kerinci, Tapanuli, and Aceh has homoceluler and uniseriate ray where Aceh ecotype have the longest ray. Furthermore, Kerinci and Tapanuli ecotype have potential as climate indicator eventhough showed negative correlation, that Tapanuli ecotype show the best result and recommended in dendrochronology study.

Abstract

Malapari (Pongamia pinnata (L.) Pierre) is an oil-producing plant which has the potential for biodiesel feedstock. This becomes a reason that Malapari plants need to be developed and cultivated. Malapari grow naturally in lowland forests on calcareous soils, rocks on the beach, along the edge of the mangroves and along stream and river tides. This study aims to determine the characteristics of Malapari and relationship between the two accessions grown in North Bali (Pemaron, Uma Anyar, Kalisada, Pengulon, Sumber Kelampok) and East Java (Alas Purwo National Park and Baluran National Park) based on morphological characters and oil content. The research was conducted in July-November 2015. The method used in this research was observation of morphological characters as well as the analysis of the oil content of seeds. Relationship among trees that grow in the two accessions was analyzed using Minitab Vis 14. Results showed that there were differences in morphological characteristics, namely the leaves, flowers, fruits, pod and seeds dimension and oil content.  Analysis of relationships among trees at similarity level above 80% classified them into 3 major groups, namely group I Malapari from Uma Anyar village with similarity level of 59,51%, group II Malapari from  Pengulon village with  similarity level of 80,16% and group III  Malapari from  Alas Purwo National Park and 32 other trees from various villages  having similarity level of 84,53%.

Abstract

The aim of the research is to analyse germination percentage, effect of coconut water addition in the media to number of last stage embryos and development of final stage D. anosmum Lindl. embryo. Research was conducted at Plant Structure and Development of Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences University of Udayana and UPT. Balai Benih Induk Tanaman Pangan dan Hortikultura Provinsi Bali from February 2015 to July 2015. Three type of media were employed, i.e. PDA, Organic, MS. Three different concentration of coconut was added to media, i.e. 0 ml/L 50 ml/L, 100 ml/L. Results showed that seed D. anosmum Lindl. on PDA, Organic and MS has not germinated yet on all media, only swollen cells observed. Seed dormancy and maturity of seed were the main factors affecting seed germination.  Addition of 100 ml / L coconut water in MS showed that media is capable to increase the formation of final stages embryos (> 32 cells). Embryo development on PDA and Organic largely showed cell stage embryos 1 to 8 cells, while MS media already showed embryo development stages of > 32 cells.

Abstract

The fungal-related diseases were responsible as one of many reasons for low production of maize in Indonesia. Controlling fungal contaminants using chemical is hazardous for human nowadays. Thus the need of environmental friendly vegetative-based fungicide such as from the extract of Ampupu tree bark is important. The objective of this study was to investigate the antifungal effect from Ampupu tree bark crude extract in response to growth of Fusarium sp, which responsible as the causal agent of corncob rot. The inhibition test on growth of Fusarium sp. by Ampupu tree bark crude extract was performed with diffusion well method on PDA as media. The process involved the infusion of crude extracts at 1.5%, 3.0% and 4.5% concentration, respectively, into diffusion well on each Petri disk. The result showed that by in vivo treatment, crude extract of Ampupu tree bark with concentration of 1.5%, 3,0% and 4.5%, were able to inhibit the fungal growth of Fusarium miniliforme as the causal agent of corncob rot with diameter of inhibition zone 0.18 mm, 1.85 mm and 2.01 mm, respectively. The higher the concentration of the crude extract given, the larger the diameter of inhibition zone formed.
