Abstract

The estimation of genetic parameters for stem diameter and plant height of ironwood (Eusideroxylon zwageri T. et B.) was conducted in a progeny trial in Bondowoso, East Java at the age of 5,5 years. The trial was arranged in an incomplete block design, which comprised of 49 families from three provenances (Batanghari, Berau and Kutai Kertanegara) with 4 replications and single tree plot. Families of Batanghari provenance showed the best growth of stem diameter and plant height compared with another provenance. There was significant difference in plant height between families within provenance, whereas stem diameter was not significantly different both of between provenance as well as between families within one provenance. Non-genetic or environmental factors provide considerable influence on plant growth in the progeny test of ironwood until the age of 5.5 years; it was indicated by the residual variance component. Individual heritability for plant height was considered as high (0.37) and stem diameter was considered as moderate (0.26). There was a strong genetic correlation between the stem diameter and plant height (0.95). This information is very important for future genetic improvement of ironwood.

Abstract

This research purposes to identify the pathogen causing leaf spot in cempaka seedling and its control technique. Identify cause of disease is necessary to know precise technique control. Identification of disease was conducted in macroscopic appearances and microscopically to determine pathogens. Identification is done by using the determination key of fungi. The results showed that the early signs of leaf spot disease on cempaka seedlings in the nursery are streaks or spots on the leaf surface with distinct boundaries. Leaf spots are formed generally brown surrounded by darker boundaries. The result shows leaf spot disease on cempaka seedling was caused by fungal pathogen Colletotrichum sp. Techniques for controlling the disease can be done by isolating the infected seeds, reducing the intensity of canopy, and using the appropriate fungicides.

Abstract

Tiwoho mangrove forest islocated in north coast of North Sulawesi province.This area functions as life buffer system for community and sustainability of Bunaken National Park. Due to the important and strategic roles of mangrove in protection and ecological functions, therefore, it is needed to know scientific information about mangrove population dynamics. This research aims to know the vegetation composition and structure vegetation of Tiwoho mangrove forest. Data collection used 20x20 m sample plots that were sistematically laid from the sea to the land side up to the highest tidal line. Distance between plots along 25 m. Results showed that at tree level Sonneratia alba had the highest Important Value Index (IVI) of 206,88 % and Brugueira sp of 46,06 %. Although Rhizopora apiculata value is lower than Brugueira sp. But the values of relative frequency of these species are almost similar. It means that both species are frequently found in observation plots. Rhizophora apiculata dominate at pole and sapling levels, but frequency of occurance this species is lower than Brugueira sp in pole level.

Abstract

Cover crops establishment followed by mycorrhizal inoculated tree plantation accelerate limestone quaryy restoration. Soil mesofauna is a useful indicator for assessing biodiversity recovery, as they are sensitive to human disturbance and involved in ecological processes. In this research, soil mesofauna presence used to evaluate limestone quarry restoration by cover crops and mycorrhizal inoculated tree esatblisment. Soil mesofauna are measured using individual density, species diversity, richness and important value. The study was conducted in four types of areas on limestone postmining lands are open areas/natural conditions without planting, cover crop area, non mycorrhizalinoculated plant area and mycorrhizal-inoculated plant area. The result showed The higher individual density, diversity and species richness of soil mesofauna on cover crops and mycorrhizal inoculated plant area than other areas are indicators of limestone quarry restoration rate. Furthermore the presence of Formicidae family that dominated on cover crops and mycorrhizal inoculated plant area, and emergence of Acari group only on mycorrhizal inoculated area also an indicator of limestone quarry restoration.

Abstract

Most of primary forest after exploitation era in Indonesia was converted into secondary forest including Forest Management Unit of Poigar. On the other hand the understanding of forest vegetation will help ecology restoration efforts. This study aims to analyze the structure, composition and tree species diversity of Inobonto Poigar I. In order to accomplish the proposed objectives, 31 plots of 20 m x 20 m were randomly established in the forest area where number and name of tree species in each plot was identified and counted. The research was conducted on September 2014 and recorded a total of 78 species within measured plot. The average basal area of the forest was 16,77 m2/ha and the size class distribution was different from primary forest which is resembled a reserved J-shaped pattern. Trema orientalis was found as the dominant species among tree and pole levels, whereas Piper sp. dominated sapling level respectively. The Shannon-Wiener index showed that sapling has the higher diversity than tree and poles. The result of structure and composition analysis of vegetation has indicated that Inobonto I forest is secondary forest.

Abstract

The productivity of manglid (Magnolia champaca (L.) Baill. Ex Pierre) as the prominent plant commodity in West Java, can be improved by environmental manipulation such as spacing and fertilization. The objective of this research is to identify the effect of plant spacing and the use of goat urine as the leaves fertilizer on manglid planting until 19 month old. We used Randomized Block with Split Plot Design using three times replication. Main factor to be considered is the plant spacing with three different space :3 x 3 m (J1) ; 2 x 3 m (J2) and 2 x 2 m (J), while the secondary factor is three different doses of goat urine given : control (P1), 240 ml (P2), and 480 ml(P3. The results showed that the best treatment of planting manglid were treatment spacing of 2 x 2 m with goat urine fertilizer application as much as 240 ml per plant that produces high 191,5 cm and 3.83 cm of diameter up to the age of 19 months.
