Abstract

The development of remote sensing technology makes it possible to utilize its data in many sectors including forestry. Remote sensing image has been used to map land cover and monitor deforestation. This paper presents utilization of ALOS PALSAR image to estimate and map aboveground biomass at natural forest of Bogani Nani Wartabone National Park especially SPTN II Doloduo and SPTN III Maelang. We used modeling method between biomass value from direct measurement and digital number of satellite image. There are two maps which present the distribution of biomass and carbon from ALOS PALSAR image with 50 m spatial resolution. These maps were built based on backscatter polarization of HH and HV bands. The maps indicate most research area dominated with biomass stock 0-5.000 ton/ha.

Abstract

A progeny trial of nyawai (Ficus variegata Blume) with subline system was established in Mangunan, Bantul, Yogyakarta and designed as a Randomized Completely Block Design. Lombok subline comprised of 17 families and Cilacap-Pangandaran subline comprised of 19 families. This study was aimed to observe  growth variation and genetic parameter of these sublines  at two years after planting. Varians analysis was performed  to find out family  effect on survival,  height, and diameter traits.  Component varians analysis was used to estimate coefficient of genetic variation and heritability. This study showed that survival rate of the trial ranged from 89.01%  to 91.42%. Family effect on height and diameter variation was very significant at both sublines. Estimation coefficient of genetic variation for height and diameter traits ranged from 4.41% to 9.04% or categorized as intermediate. Individual heritabilities for height traits ranged from 0.15 to 0.22;  diameter ranged from 0.18 to 0.09, while family heritabilities for height and diameter traits  ranged from 0.49 to 0.60 and 0.29 to 0.66 respectively.

Abstract

It was estimated that North Sulawesi needs 9,870,093.33 coastal vegetation seeds to rehabilitate the damage of coastal ecosystems which reach 14,805.14 ha, where the largest area 13.884 ha located in other land use. This study aims to provide information of seed germination techniques in Permanent Nursery Kima Atas, Manado. Research was arranged in complete randomized design as factorial with three replications. Ketapang (Terminalia cattapa) will obtain high viability in fluctuation of temperature and humidity, i.e used sand media, without wildlings and placed under 25% shade and rain. Keben (Baringtonia asiatica) through the incision and decay that placed in the open location will obtain viability until 90% within 2 months. Nyamplung (Calophyllum inophyllum) requires shell splitting in order to improve the viability and it can be done by cracking and stripping.

Abstract

The objective of this research is to evaluate the ecosystem functions through vegetation and wildlife indicators.  Methods used are vegetation analysis and direct indirect method to count wildlife .  Results show that the dominant type of land coverage in Gunung Ambang Nature Reserve is open secondary forest, where shrubs, rattan, and epiphytes dominated.  This might lead to vulnerability of the site toward disturbance.  Furthermore, it was indicated that this area still contains local wildlife species such as Babyrousa babyrussa celebensis.  Eventhough land degradation has become a significant issue, the status of Gunung Ambang as nature reserve has limited restoration attempts both vegetatively and mechanically.

Abstract

The present study aims to determine the type of fodder available and the level of scarcity of Anoa’s fodder at the condition prior to captivity at the Forestry Research Institute of Manado. The method employed was a trial of 12 (twelve) types of fodder available around the captivity site given to 2 (two) female anoas. The data were analyzed and displayed in tables and graphs while the data of preferred fodder were analyzed using Neu’s index equation. The findings suggest that anoa put in captivity at the Forestry Research Institute of Manado did not encounter problems during the process of feeding adaptation. The average fodder needs required anoa at the captivity site of  the Forestry Research Institute of Manado range from 10.2 to 11.7 kg/ day in which the fodder was given twice a day. Meanwhile, based on the availability and ease of supplying the fodder from around the captivity site, the following are the types of fodder from higher to lower preferences, namely: field grass, kangkung, shoes banana, string beans, beans and cucumbers, respectively. While fodder with the lowest level of scarcity is the type of fodder with a hard texture such as sweet potatoes, carrots or potatoes. Based on the results of a number of studies, it is recommended that variations in anoa’s fodder can be done every 4-5 times a day.

Abstract

Teak (Tectona grandis) is one of popular and important carpentry wood in Indonesia. However teak production for carpentry material cannot balance the increasing need for domestic and export market. The increased production from small holder forest can be alternative way to supply national wood need. Therefore science and technology play role to support forest productivity eg superior seedling from vegetative propagation. The preparing of superior seed took several steps i.e. selection from mother tree, genetic material extraction, grafting activity using budding technique, hedge orchard establishment, and mass production used cutting rotted or tissue culture. From clonal test we can derive superior seed which adaptive with development location and has better productivity.
