This research aims to investigate the influence of media (topsoil and cocopeat) and seed treatment (control, immersion, cracking, and stripping) on the growth of nyamplung seeds from Talise Island on 3 months old. This research using Completely randomized design method with observations viability, height, diameter, robustness seedlings and seed quality index. Results of tests known that character nyamplung growth is influenced by the media and seed handling. Cocopeat media will improve the viability but debase of growth, so that the necessary weaning with a more fertile medium. Handling seed by stripping the shell has a good influence on the growth and quality of seeds. Based on research, nyamplung requiring scarification with cocopeat media and stripping the shell.

This study aims to determine the suitability of using cocopeat as planting media at transplanting containers in the polytube of the cempaka seedlings growth. The method used in this research was implementing a trial use of cocopeat as transplanting media in the polytube and being compared to the growth of cempaka seedlings in polytubes and polybags containing topsoil. The parameters observed included percent survival (%), height (cm), and diameter (cm) of the plants. Through the t-test it was shown that the parameters of diameter, height, and percent survival of the cempaka seedlings using cocopeat as a transplanting media were significantly different than those using top soil as a transplanting media.

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.

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.

The aim of this experiment was to identify of survival percentage, height plant and stem diameter of Alstonia angustiloba progeny trial at 2 year old to support the provision of improved seed. This experiment was arranged in randomized complete block design. The research used 2 factors, i.e. population sources (Carita-Banten, Pendopo-Muara Enim, Lubuk Linggau-Musi Rawas and Solok-West Sumatera) and parent trees (43 parent trees). In this experiment, parent trees factor was nested in the population sources. The result shodwed that survival percentage, height plant and stem diameter of Alstonia angustiloba progeny trial at 2 years old in Wonogiri were 82.07 %, 2.43 m and 2.85 cm, respectively.

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.
