Abstract

The determination of the conversion rate (1.04) for certain types of wood still contains weaknesses, this is caused by bontos diverse forms. Where the measurement results will be very different for logs that have bontos cylindrical shape with a cylindrical timber that is not or has buttresses. It is necessary for research that aims to determine how much the conversion rate measurement volume of logs in the water compared to the measurement volume of logs on land for Meranti (Shorea spp). Logs were observed and measured the average diameter of at least / lowest is 60 cm by 50 stems. Implementation of measurement include: measuring the length of logs on land and in water, measuring the diameter of logs on land and in water as well as the determination of the volume of logs on land and in water. From the results of statistical analysis using the t test in one direction, the result is greater than the figure of 2.17 t tables for 5% significance level = 1.67 and smaller for a very real level of 1% is 2.40, which means that Ho is rejected on the the real rate of 5%, which means that the diameter measurements on land and in water / river for Meranti (Shorea spp) influence the treatment of the measurement method because it produces a real difference.Keyword : Conversion Rate, Grading, Log, Shorea spp

Abstract

Bats (Chiroptera) are the only mammals that can fly. Bat habitats are in caves, large trees in the forest, hollow trees, coconut trees, banana trees and roofs of buildings. Bats are nocturnal, they forage at night and sleep during the day by hanging upside down. Teluk Akar Bergantung has a generally flat and swampy topography, with a small portion submerged in water. Various types of trees have grown, one of them is Beringin/Kayu Are, which is where bats live. Bats play a role in the balance of ecosystems as seed dispersers, flower pollinators, insect controllers and guano producers. Based on the potential in this area, the research aims to collect data on various types of bats in Teluk Akar Bergantung, Ketapang regency, West Kalimantan. The method used is catch and release method using mist nest. Data analysis of the research used bats identification guide written by Suyanto (2001) entitled “Kelelawar di Indonesia” and “Panduan Lapangan Mamalia di Kalimantan, Sabah, Sarawak dan Brunei Darussalam” by Payne et. al (2000), diversity index (H’), equitability index (e), dominance index and species richness (d). The result of research obtained 14 individuals consist of 6 species (Vampir palsu (Megaderma spasma), Codot mini (Cynopterus minutus), Codot krawar (Cynopterus bracyothis), Codot horsfield (Cynopterus horsfieldii), Codot kecil kelabu (Pentethor lucasii) and Codot pisang-coklat (Macroglossus minimus), belonging to 2 families (Pteropodidae and Megadermatidae). Diversity index is in the medium category (1,47), the equitability index is in the high category (0,82), no type of bats that dominates (0,31) and the species richness is in medium category (2,79).                                                   Keywords: bats, diversity, Teluk Akar Bergantung, urban forest

Abstract

This study was conducted to determine the diversity of vegetation species that compose mangrove forests in the village of Medan Mas, Kubu Raya Regency. Measured parameters of important value index , dominance index (C), species richness index (RI), species evenness index (e) was carried out using the survey method by means of a plot. The placement of the research path was done (purposive ). The path made in this study is 10 meters wide (5 m to the left 5 m to the right) and the path length is adjusted to the conditions in the field to the river boundary. From the pathway, a sub-plot is made with a size of 10 m x 10 m for the tree level, and 5 m x 5 m for the sapling level and 2 x 2 for the seedling level. The results of this study indicate that the types found in the field amounted to 12 species for seedlings, 10 species for saplings and 9 species for trees. . Based on the results of the data obtained, it is known that the index value of species diversity (H) at seedling, sapling and tree levels shows a number <1. This means that the value of species diversity found in mangrove forests in Medan Mas Village is relatively low. Forests with low species diversity values indicate that the forest area has experienced forest disturbance or damage. When data collection is carried out in the field, there are several locations that experience disruption or damage in the form of logged-over or transfer functions as shrimp ponds.Keywords: Mangrove Forest, Vegetation Diversity
