<![CDATA[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. ]]>

<![CDATA[This study was conducted to evaluate plant growth of Intsia bijuga at 5 years old in Sobang, Banten for supplying good genetic material in the future. Establishment of the trial was conducted in 2007 using Randomized Complete Block Design (RCBD) that consisted of 6 blocks, 100 families nested in 10 provenances, 4 treeplot for each family with a spacing of 4 x4 m. Measurements were taken periodically every year on the survival percentage, total height and stem diameter at the breast height or dbh. At the age of 5 years showed that the significant differences among provenance in survival percentage that ranged from 41.61 to 65.11 %, Â average of plant height were 1.04 to 2.82 m and dbh 1.24 to 1.59 cm. The growth variation families also showed significant differences in height and diameter. The survival rate ranged from 12.5-91.67 %, average plant height were 0.52-2.55 m and dbh 0.90-2.44 cm. Individual tree heritability estimate for height was height (0.344) while that of diameter was moderate (0.259). Family heritabilities for height and diameter was considered moderate, namely 0.573 and 0.491 respectively. Genetic correlation between height and diameter growth was positive and high (0.834).]]>

<![CDATA[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.]]>

<![CDATA[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.  ]]>

<![CDATA[The present study aims to determine the type of fodder available and the level of scarcity of Anoaâs 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 Neuâs 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 anoaâs fodder can be done every 4-5 times a day.]]>

<![CDATA[This study aims to analyze and develop alternative forest and land rehabilitation based on land capability in catchment area Tondano lake. Inhibiting factors used in the analysis is the ability of land slope, drainage and infiltration rate. The results of the analysis obtained 42 units of land. Approximately 85 % belong to the class I - V and 15 % belong to the class VI-VIII. Furthermore, the proposed three models of forest and land rehabilitation as follows: (1) Sub East catchment area, proposed pattern-based agroforestry clove plants in cultivation area, (2) Sub South catchment area, proposed pattern of farm crops is designed in agroforestry systems so that the health of soil, especially soil organic matter content can be maintained to support sustainable agriculture, (3) Sub West catchment area, proposed pattern integrated farming cattle crops (maize + grass strip + terrace ridges). While in the forest area developed multi purposes forest on all catchment areas.]]>
