Abstract

Mindi (Melia azedarach L.) is mostly found in community forests of West Java. One of the factors that affect productivity of mindi plantation is high quality seed that is not easily available. Seed sources of mindi should be established based on the status of genetic variation, preferably the one with high genetic variation. However, information on the status of genetic variation is always lacking. The research objective was to estimate genetic variation within and between populations of mindi in West Java community forests based on microsatellites. Six mindi populations were selected in the following villages: Nagrak (Bogor),Babakan Rema (Kuningan), Padasari (Sumedang), Legok Huni (Wanayasa), Sukakarya (Bogor) and Gambung (Bandung).The results showed that average number of alleles was 2.750, PLP (percentage of polymorphic loci) was 91.67%, and the genetic diversity within populations (He) was 0.366. The highest genetic diversity was found in Padasari (He = 0.454), and the lowest one was in Babakan Rema (He = 0.269). The genetic difference between populations (Fst) was 0.3030. Cluster analysis showed three groupings in which the first and second clusterconsisted of Nagrak and Padasari, as well as Babakan Rema, Gambung and Sukakarya, respectively. On the other hand Legok Huni was separated alone. The findings provided information on the moderate status of genetic diversity that may be considered during the selection and establishment of seed sources.Key words : community forests, genetic diversity microsatellite, mindi (Melia azedarach L.)

Abstract

Pulau Sebuku mangrove forest, South Kalimantan, is part of Pulau Sebuku Nature Reserve that needs to be protected as close as naturally. This study is aimed to explore the species composition and structure of mangrove forest in Pulau Sebuku. The results showed that Pulau Sebuku mangrove forest has low species diversity and high evenness. Total species of mangrove tree, forest regeneration, and other habitus consists of 10 species (Bruguiera gymnorrhiza, B. parviflora, Ceriops tagal, Rhizophora apiculata, R. mucronata, Sonneratia alba, Heritiera littoralis, Xylocarpus granatum, Nypa fruticans, and Acrostichum aureum). R. mucronata (bakau) is the dominant species in almost all locations of observation. Horizontal structure of Pulau Sebuku mangrove forests tend to L-form, which evolved towards a balanced uneven-age forest. Based on the floristic composition, structure and general appearance of the forest, mangrove forest communities in Pulau Sebuku grouped into 3 types, among others: shrub communities (bakau-perepat), young mangrove communities (bakau and bakau-lenggadai), and nypa community.Key words : forest structure, mangrove forest, pulau sebuku, species composition.

Abstract

Forest fire is one of the factors affecting environmental-damage that have been occuring frequently in Indonesia for the last two decades. It is a serious problem that, though, it has not been controlled optimally yet. Climatic condition highly affects forest fire occurence, in term of the frequency, magnitude, season, and the effects. Climatic factors including temperature, humidity, precipitation, wind, and air stability directly affect the potential of forest fire occurence through fuel availability and fire spread. This study was conducted to analyze the correlation between climatic factors and forest fire occurence in KPH Bogor. The result shows that the correlation between climatic factors and forest fire could be modelled through regression analysis. The strongest correlation between climatic factors and forest fire occurrence was indicated by monthly rainfall as the factor affected moisture content of forest fuel.Key words: climatic factors, correlation, forest fire, KPH Bogor, rainfall

Abstract

Counting the number of chromosomes can be conducted by analysis of chromosomes with chromosome staining. The purpose of this research is to find the right method for staining chromosomes of teak, time of the mitotic phase of teak, and the duration of the mitotic phase of teak. Overall, to get good results, chromosomal analysis is done through four stages in the sequence was (1) the early phase of treatment, (2) stage of fixation, (3) stages of maceration and (4) stage of coloration. In this study, there were seven methods of making preparations applied to the root tip mitosis, chromosomes are stained onion root (method A), modification of maceration (method B), modification without fixation and maceration (method C), modifications time to cut teak root (D method), modification of maceration without fixation (method E), the modification of pre-treatment without fixation and maceration (M method), and storage of the root tip before pre-treatments (method G). Chromosome staining onion roots used as a basic for the staining method is easy to get the correct teak’s chromosomes. From this study, analysis of teak’s chromosome is known that D chromosome staining method is appropriate because the methods and stages of mitotic chromosomes can be seen, but the number of chromosomes can not be calculated because the size of chromosomes were very small. the best time to cut the teak root at 9:00 to 10:00 am, and the duration of the mitotic phase of teak is ± 1 hour.Key words : chromosome, chromosome staining method, mitotic, Tectona grandis

Abstract

Three different types of solid and liquid media were used to determine radial growth and biomass production of Beauveria bassiana. Radial growth in solid media was observed for about 15 day after inoculation by measuring the fungal colony diameter every 24 hours. Maximum average growth is obtained in SDAY media (5.31 cm) followed by PDA(4.79 cm) and MEA (4.21 cm). While SDBY (0.24 g) as the liquid medium used for the biomass production after 4 weeks of incubation obtained the highest biomass followed by MEB (0.19 g) and PDB (0.18 g). The result showed that Sabouraud Dextrose with Yeast Extract is the most suitable medium for B. bassiana growth.Key words : Beauveria bassiana, media, radial growth, biomass production
