Abstract

The importance value index and diversity are important indicators to determine the dynamics and stability of the vegetation community. The objectives of the study were (1) to determine the importance value index of seedlings, saplings, poles and trees composing the Bruno Forest community in SUBKPH Lumajang (2) to know the diversity of seedlings, saplings, poles and trees composing the Bruno Forest community in SUBKPH Lumajang. The research was conducted in the Bruno Forest Area, SUBKPH Lumajang, East Java. The plot method was used in this study with nested plots measuring 2x2m2 for seedlings, 5x5m2 for saplings, 10x10m2 for poles, and 20x20m2 for trees. The number of samples was 30 plots placed systematically, with a distance between plots of 20m. The conclusions of this study are (1) the forest vegetation community of Bruno Forest area is composed of 9 species belonging to 6 families, at tree level dominated by Pinus merkusii, at pole level by Swietenia macrophylla species, saplings and seedling level dominated by Calliandra surinamensis (2) Diversity at tree and pole level was categorized as high while at sapling and seedling level was categorized as moderate. The species evenness index at the tree, pole and saplling level was categorized as high, while at the seedling level it was categorized as medium.

Abstract

The development of modern industries has demanded ever-increasing usage requirements for wood products. The use of wood will be more effective and efficient if the properties of wood are known beforehand. This study aims to determine the anatomical diversity of sengon wood and its possible use as a raw material for furniture. This study used a randomized block design with Tukey's follow-up test. The factor used consisted of the radial direction of wood (wood near the skin and wood near the heart). Parameters observed were the proportion of fiber cells (%), the proportion of vessel cells (%), the proportion of parenchyma cells (%), and the proportion of radius cells (%). The results showed that the wood near the skin and near the heart of sengon had variations in the proportion of fiber cells, the proportion of vessel cells, the proportion of parenchyma cells and the proportion of radius cells. The average value of the anatomical diversity of sengon wood in the radial direction is the proportion of fiber cells 49.02 - 50.24 %, the proportion of vessel cells 23.22 - 24.23 %, the proportion of parenchyma cells 13.47 - 14.57 %, the proportion of finger cells finger 11.53 - 13.39 % and . Sengon wood can be used as furniture material for light buildings or for artificial boards because it has a high proportion of fibers.

Abstract

Eucalyptus sp is a type of exotic plant that is cultivated in Riau Fiber. Particularly in terms of soil, this Eucalyptus species was developed in soil management unit B and soil management unit C. Differences in variations in plant growth in the two land management units are not known with certainty because there is no accurate information. This research was conducted at the East Teso Estate which is one of the forest management units of Riau Fiber which included measuring tree height with variations in age of 6 months, 12 months and 18 months, as well as tree diameter and calculating the percentage of single trees with variations in age of 12 months and 18 months. in the land management unit B and soil management unit C which were tested using the t-test at a test level of 5%. The results showed that height growth had a significantly different effect on the two soil management units, namely 4.39 m in soil management unit B and 3.62 m in soil management unit C at 12 months of age and 6.43 m in soil management unit B and 5.87 m in soil management unit C at 18 months old. As for plant height at 6 months, diameter and percent of single trees aged 12 months and 18 months, the results were not significantly different in soil management unit B and soil management unit C.

Abstract

Fern weeds control with chemical herbicide in peat area is one solution to overcome weeds competition against cultivated plants at timber estate. Type of active component and solution concentrate of herbicide are effect on weed control result. The purpose of this research are to know weed species and its density, and effect of  active component type and solution concentration of herbicide against weed mortality percentage and weed mortality start time. Results of the research showed that Stenochlaena palustris weed was dominated at peat area with 3.986/Ha density. Ammonium Glufosinat herbicide with 1,6% solution concentration was effective to control fern weeds with 100% weed mortality and start time of weed mortality was 3 days after herbicide application.

Abstract

Community forests in Gunungkidul have developed for a long time and are managed in a traditional way, known as pekarangan, moor and wono. Most of the community forest planting patterns found in Semoyo Village are agroforestry patterns, where trees are planted with a mix of various tree species and one type is dominated, for example teak or mahogany. This study aims to determine the differences in the shape of the diameter distribution of mahogany and teak in dry fields and yards which are dominated by one tree species. The method used is quantitative analysis to produce diameter distribution and draw a curve to describe the stand structure. The results showed that for the type of mahogany in the yard and moor in all class diameters, the number of trees was higher than teak. The diameter distribution of mahogany and teak both in the yard and dry land both showed a shape that resembled an inverted J and was successfully modeled using the exponential model.
