Abstract

The purpose of this study was to determine the average height, diameter and average volume of teak trees (Tectona grandis Linn f.) Planted in 2010 at PT. United Tractors, Tbk Kelurahan. Loa Bakung District. Kukung River in Samarinda City. The results of this study are expected to be taken into consideration for the development of teak plants (Tectona grandis Lnn.f.), Especially in East Kalimantan. The measurement results of teak plants (Tectona grandis Linn.f) aged 7 years were 200 trees with a spacing of 2 m x 2 m with an area of ​​800 m2 in the area of ​​PT. United Tractors Tbk, obtained data on average height of 11.381 m, with a minimum height of 4.37 m, a maximum height of 18.35 m, a standard deviation of 2.97 m and a coefficient of variation of 26.12%. The average diameter is 11.299 cm, the minimum diameter is 2.81 cm, the maximum diameter is 19.33 cm, the standard deviation is 3.31 cm, and the coefficient of variation is 29.37%, the average volume data is 0.095 m3, the minimum volume is 0.002 m3 , the maximum volume is 0.264 m3, the standard deviation is 0.0958 m3, and the coefficient of variation is 62.02%.

Abstract

The understorey functions as a ground cover that maintains moisture so that the rapid decompositionprocess can provide nutrients for the main crop the nutrient cycle can take place perfectly, theavalanches that fall as litter will be returned to the tree in the form of nutrients which, as is known, willbe broken down by bacteria and microbes. This study aims to determine the type, number, andpresence of each understorey in the area of the Samarinda State Agricultural Polytechnic ForestManagement Study Program, precisely behind the Silviculture Laboratory. The research method useda single plot measuring 60 m x 32 m with sub plots measuring 2 m x 2 m which were arrangedsystematically so that there were 480 sub plots.The results of the study found as many as 23 speciesof understorey which were included in 22 genera, 18 families, as many as 14.616 individuals, in1.528 attendances. The most common species found were Asystasia intrusa as many as 5.728individuals with distribution in 304 plots, then Clidemia hirta (L.) D.Don with 1.864 plants withdistribution in 240 plots and Stenochlaena palutris (Burm.f.) Bedd species. as many as 1.344 with adistribution of 56 plots. While the types of Alpina sp and Imperata chylindrica as many as 8 plant in 8plot.

Abstract

Sengon (Paraserianthes falcataria) is a plant that can grow in a wide climate distribution, but is easier to grow in the tropics. This plant has a high viability because of the root culture that plunges into and widens to the side. Even between the size of the stem and the size of the roots are almost balanced. The broad and deep root reach that causes sengon (Paraserianthes falcataria) to have a high vitality. Sengon (Paraserianthes falcataria) has a taproot. The stem is round without buttresses. The purpose of this study was to determine the average height and average diameter of sengon (Paraserianthes falcataria) trees (Paraserianthes falcataria) aged 10 years. The expected results of this research as input for the development of sengon (Paraserianthes falcataria)trees in Desa Perdana, Kecamatan Kembang Janggut, Kabupaten Kutai Kartanegara. The research method used is census namely the measurement technique carried out as a whole or 100% measurement (full enumeration). The results of measurements and calculations for the diameter, height and volume of sengon (Paraserianthes falcataria) plants aged 10 years with a spacing of 3 mx 3 m as many as 424 trees with an area of 4,000 m2 in Desa Perdana, Kecamatan Kembang Janggut, obtained the following results: minimum diameter value of 7 ,9 cm, the maximum value diameter is 27 cm and the average diameter is 17,32 cm, the standard deviation is 3,67 cm and the coefficient of variation is 21,23%, while the minimum value is 10,00 m, the maximum value is 26,32 m, and the average height is 16,78 m, the standard deviation is 2,46 m and the coefficient of variation is 14,68%, minimum volume value of 0,063 m3, the maximum value volume is 0,96m3 and the average volume is 0,299 m, the standard deviation is 0,15 m3 and the coefficient of variation is 50,29%,

Abstract

The urban forest is a community of vegetation in the form of trees and their associations that grow on city land or its surroundings. Air pollution that occurs in the urban forest reduces air quality so that its quality decreases to become unusable as it should be. The purpose of this study is to measure and identify driving noise and compare with environmental quality standards. The procedure of this research different density of vegetation from 2016-2020 has passed the Quality Standard, based on the criteria of Keputusan includes the stages of activity, namely field orientation to determine the point of Mahakam City Forest road length is 143 m, noise sampling points as many as 3 points with a distance per point is 71.5 m. The results of this study indicate that the number of vehicles passing by, the density of vegetation in the Mahakam Bridge City Forest is a factor in reducing the intensity of noise, where each measurement point has a Menteri Negara Lingkungan Hidup Nomor 48/MENLH/11/1996 tentang Baku Tingkat Kebisingan.
