Abstract

The procurement of good quality seeds for the development of mindi (Melia azedarach L.) in the community forest is absolutely necessary. The purpose of this research is to investigate the diversity of the viability and seedling vigor of mindi from different populations with various treatments of dormancy breaking. The sample materials were mindi seeds that were collected from 6 locations (6 seed lots) or seed sources which were located in the community forest of West Java. There are 10 treatments of dormancy breaking that were applied in this study. The experiment design was Randomized Complete Design (RAL). The breaking dormancy was focused to the delignification of hard seed coat. Results showed that the most effective dormancy breaking for mindi seed was soaking in consentrated Sulfuric Acid (H2SO4) as long as 30 to 45 minutes. The first count for germination of mindi was on the 16 day and the final count was on the 31 day.The average value of germination percentage (DB) for all seed sources was 40 %, while the highest which is 60% was mindi from Sumedang seed source. The highest value of germination rate that is 6,543%/etmal was seed from Sumedangand seed from Gambung was the lowest (1,400 %/etmal).

Abstract

The Nature Reserve of Panjalu Lake is one of the oldest conservation area in Indonesia. As a conservation area, Panjalu Lake has different species of flora that are useful as germplasm conservation, science and education. This study aims to know the potential of vegetation species diversity for ecotourism development at Nature Reserve of Panjalu Lake. The inventory method used is line plot sampling with intensity 15 % in two paths of 500 m (adjusted according length of the area) and 20 m width. Spacing between lines is 200 m and spacing between observation plot is 100 m. Within each path, 50 m x 20 m observation plots were established. The results showed that there are three species of seedlings with highest IVI, namely: Dysoxylum densiflorum Miq. (47.64 %), Calamus zollingerii (47.64 %), and Sterculia macrophylla Vent. (44.37 %). The four species at sapling stage with highest IVI are: Litsea cassiaefolia (114.29 %); Dysoxylum densiflorum Miq (57.14 %); Litsea sp. and Endiandra rubescens Miq (14.29 %). Three species at pole stage with highest IVI, namely: Dysoxylum densiflorum Miq. (143.04%); Litsea cassiaefolia (99.78 %) and Artocarpus elasticus Reinw 9.53 %). Three species at tree stage with highest IVI, namely: Dysoxylum densiflorum Miq (147.924 %), Litsea cassiaefolia (68.753 %), and Eugenia fastigiata Miq ( 31.410 %).

Abstract

Secondary forest of Indonesia covered about 24.2 % of total land area and dominated by post logging forest. The discourse to manage all forest area into Forest Management Unit (FMU) as the smallest management unit has been established, including post logging secondary forest. Therefore, understanding the diversity of secondary forest vegetation will help to decide its future management. This research aims to analyze composition, diversity and structure of post logging secondary forest at Nunuka, North Bolaang Mongondow of North Sulawesi. In order to accomplish the proposed objectives 30 plots of 20 m x 20 m were established in research area where number and name of tree species were identified and counted. The research was conducted on November 2014. The result recorded 84 tree species in research area. Anthocephalus macrophyllus dominated tree phase, whereas Eugenia sp. dominated both of poles and sapling. Shannon-Wiener index indicated low and medium diversity, whereas species abundance of tree, ploes and sapling were almost spread evenly. Vegetation density over all vegetation phases was 485.83 tree/ha, the average basal area of the forest was 35.15 m2/ha and the size class distribution did not resembled a reserved J-shaped pattern as found in primary forest. However J-shaped pattern showed in graphs of ten dominant species in both of tree and sapling level.

Abstract

This research aims at measuring carbon (C) stock of gmelina (Gmelina arborea Roxb.) agroforestry system and its carbon diynamics due to several harvesting rotations. Observation was conducted during March – October 2014, on 17 plots in private forest, located in Tasikmalaya and Banjar District, West Java Province. The C-stock measurement followed Rapid Carbon Stock Appraisal Method (RaCSA) with some additional analysis. The dynamic of C-stock was measured based on biological rotation, technical rotation-1 (harvesting at tree diameter of 15 cm) and technical rotation-2 (harvesting at tree diameter of 20 cm). The result of the study shows that average of C-stock in gmelina agroforest stand is 170 ton/ha, consisted of 64 ton/ha above ground C and 106 ton/ha below ground C. Biological rotation (8 years) results in maximum C-stock of 15 ton/ha at harvesting time, while the time averaged-C stock is 7 ton/ha/year.Technical rotation-1(14 years) and technical rotation-2 (24 years) result in maximum C-stock of 23 ton/ha and 28 ton/ha respectively, while the time averaged-C-stock are 12 ton/ha/year and 18 ton/ha/year respectively.
