Abstract

Contribution of forest for development of this nation can not be regarded as small, so that the forests must be managed and used optimally and well  preserved. As an effort to preserve and enhance timber production, PT. Sari Bumi Kusuma (PT. SBK) as one of the holders of Forest Concessionaire (IUPHHK-HA), have been applied Selective Cutting and Line Planting (TPTJ) silvicultural system in it’s management of natural forest production since 1999. Red Meranti (Shorea leprosula) is one of the flagship sppecies which are selected in TPTJ because it better growth than other Meranti sppecies.However, the growth of S. leprosula in line planting  excessively unknown yet. This research aimed to know the diameter growth of S. leprosula 5 - 9 in TPTJ silvicultural system. Research conducted in Mei 2009  in PT. SBK’s areas. Data of diameter growth collected through observation of the 100 m x 100 m sampling plots (1 ha).Plot samples were taken in each age planting which are purposively selected based on the age of 5 to 9 years old of planting, where in each of the plot samples there are five lines of planting. Analysis of research data including diameter stand structure, data normality test, Mean Annual Increment (MAI), and curve of diameter growth. Diameter growth of of S. leprosula which planted in line generally sppreading normally, where the most frequency of individual tree is in the diameter class that represents the mean (average) of the stand diameter, and show sigmoid shape curve of the diameter growth. The average increment (MAI) of S. leprosula were highest at the age of seven year plantation i.e to 2.31 cm / year and the lowest at the age of five year plantation i.e 1.45 cm / year. The largest diameter found at the age of nine years after planting i.e 28.5 cm (average 19.7 cm).

Abstract

Rapid forest exploitations can cause forest degradation, and eventually may cause the global climate change, because of that, the balance of the forest sustainability must be kept as well. The implementation of silviculture system called Selective Cutting and Strip Planting System is one of several forest harvesting method that consider the importance of forest sustainability. Practically, the system has never been tested to the last cycle. So, it is necessary to conduct some evaluation to the method to assure its sustainability. Estimation of soil quality is one of several ways to evaluate the effectiveness of silviculture implementation on a forest area, Since the soil is one of the major factor that influencing the growth of vegetations, then its quality can be used as an indication of conservation of forest productivity.

Abstract

The demand of timber for industry is increasing, along with the increasing rate of population growth. It brings an impact toward the timber demand. Increased productivity is expected able to balancing the needs without caused a damage to the forest ecosystem it self. One of the silvicultural system which suitable to be implemented in natural forest is Selective Cutting Line Planting (TPTJ) which planted with S. leprosula species. One of the effort to increase productivity is by determining the land-width which suitable with the S. leprosula species, so that it can grows optimally. The result shows that there is a correlation between the width of planting line toward the growth of diameter and height. The optimum width for the S. leprosula planting line is 6 meters.

Abstract

Mindi (Melia azedarach L.) is mostly found in community forests of West Java. One of the factors that affect productivity of mindi plantation is high quality seed that is not easily available. Seed sources of mindi should be established based on the status of genetic variation, preferably the one with high genetic variation. However, information on the status of genetic variation is always lacking. The research objective was to estimate genetic variation within and between populations of mindi in West Java community forests based on microsatellites. Six mindi populations were selected in the following villages: Nagrak (Bogor),Babakan Rema (Kuningan), Padasari (Sumedang), Legok Huni (Wanayasa), Sukakarya (Bogor) and Gambung (Bandung).The results showed that average number of alleles was 2.750, PLP (percentage of polymorphic loci) was 91.67%, and the genetic diversity within populations (He) was 0.366. The highest genetic diversity was found in Padasari (He = 0.454), and the lowest one was in Babakan Rema (He = 0.269). The genetic difference between populations (Fst) was 0.3030. Cluster analysis showed three groupings in which the first and second clusterconsisted of Nagrak and Padasari, as well as Babakan Rema, Gambung and Sukakarya, respectively. On the other hand Legok Huni was separated alone. The findings provided information on the moderate status of genetic diversity that may be considered during the selection and establishment of seed sources.Key words : community forests, genetic diversity microsatellite, mindi (Melia azedarach L.)

Abstract

Massive utilization of forest resources became one factor which caused degradation on natural forest. Forestdegradation which occurred continuously could cause a change in forest composition. This could happen becauseseedling from invasive species dominated the area of natural forest. This research aimed to determine the compositionand structure of recovering forest stands managed by TPTJ system in area of IUPHHK-HA PT. Suka Jaya Makmur,West Kalimantan. The results showed that non-commercial Dipterocarp species group had the biggest value of densityand proportion among all stages of Dipterocarp stand. Curve diameter distribution showed a balanced logged forest.The diversity in all plot-area was high. Kelampai and Meranti were dominated in canopy level. Aternatif; Kelampai andMeranti were dominant at canopy level Jambu monyet and Kelampai were the species that dominated in seedling level.Alteratif; Jambu monyet and Kelampai were the species that were dominant at seedling level Tree and seedling had adifferent composition, it was shown by the ID value at >50%. This was shown by cluster analysis which divided into fourgroups. Commercial species proportion was generally larger than other non-commercial species.Key words: forest utilization, line planting, selective cutting, vegetation recovery
