Abstract

This research has been conducted with the tittle the diversity of gastropods on the river water environment Empayang Lahat regency of South Sumatra province. The aim of this research species diversity of gastropods contained the region. This research was implemented conducted in October 2015, a river Empayang Kasap Sukajadi Lahat regency. The methods of this research is purposive random sampling method with 5 sampling stations, each station is divided into three substations (edges first, middle, edge 2) was determined by linear transects (line transect). The data of the sample was taken in the morning and afternoon. The results of this research were obtained 8 species of gastropods (Melanoides granifera, Elimia acuta, Brotia tetidinaria, Lymnae stagnalist, Lymnae rubiginosa, Pomacea canaliculata, Pila polita and Menetus sp) with 7 genus, and of the six tribes (families) of 4 order. The total index of the diversity in the river Empayang Kasap Sukajadi Lahat district was of 2.09 to 2.46. The highest levels of diversity found in the station V (2.46) and the lowest at station I (2.09). While the value of dominance index (C) with a range of 0.17 to 0.26 at five stations in the lower state, the highest level of dominance index at station I (0.26) and the lowest at station III (0.17). River water quality conditions greatly affect the existence of gastropods.

The Research of Vegetation Analysis on Reclamation Area of Coal Mine of PT. Bukit Asam Tanjung Enim, South Sumatera was aimed to determine the types of vegetation that composing reclamation area was found in PT. Bukit Asam in terms of structure and composition. The research has been done in November until Desember 2014, in four reclamation area at PT. Bukit Asam, namely the area of reclaimed the Muara Tiga Besar Selatan, Mahayung, Klawas Timur, and the Muara Tiga Selatan having different strata age. the vegetation data includes rate of growth seedlings, saplings, poles, and tree obtained through transek method in the form plot lane. In each transect made a plot in size 20x20 m for tree level, 10 x 10 for poles level, 5x5 for saplings level, and 2x2 m for seedling and cover plants level. The results of this research, in the Muara Tiga Besar Selatan area was obtained the vegetation seedlings-cover plants and saplings level, each of 17 and 7 species. In the area Mahayung are only found level vegetation of seedlings-cover plants as many of 13 species.

It was conducted at green house and Pest Diseases Plant Laboratory, Plant Protection Department, Agriculture Faculty, University of Sriwijaya. This research was aimed to know the effect of applicated ash sawdust on vegetative growth of red pepper. The Completely Randomized Design with treatments are : 10, 20, and 30 g/ kg marshland and without ash sawdust (control), with 6 replicates each treatments. The result showed that applicated ash sawdust on measure 10 g/ kg soil significantly on number of growth 53.28 cm and number of branch 9.2, but not differ on dry weight of red pepper.Keywords :  Swamp land, ash sawdust, branch, red pepper

Abstract

Point Quarter Method is a plant community structure measurement procedure. The technique is base on measurement of distance of four plants or trees in every  quarter  that is made by four space in the cross line sampling field studies. In forest sampling, point centered quarter methods is considered as the efficient, reliable and accurate data,  not only for mean distance and density, but for frequency and dominance of species. So it is important to try wether these method ould be applicated to animal, especially crab. These method was applicated for crab population in Padang Beach at December 22nd, 2014.  Ten points quartered were made and the distance of every Ocypode sp crab burrow was counted by ruler. Mean distance of crabs burrow gained by divided of total number of quarter (20) with  mean distance of every burrow to the point. Density per hectare is 10,000 m divided by quadratic of mean distance. Mean distance of burrow to points were counted and prediction of population per hectare could be found. In these case, mean distance was: 0.41 m and crab population  is :59,488.34 individu per hectare. Compared to other species , eg Scylla serrata, its population is bigger, eventhough the condition of beach is polluted and wastedKeywords: point centered quarter method, Ocypode sp, density

Abstract

Escherichia coli is one of the bacteria that cause infections in the human digestive tract such as diarrhea, while Staphylococcus aureus is one of the bacteria that cause infections in the skin injury such as boils and pimples. This study used Syzygium zeylanicum leaves because it has potential as a antibacterial because it contains active compounds. This study aimed was determine the antibacterial activity of the fraction and the active compound in Syzygium zeylanicum leaves against Escherichia coli and Staphylococcus aureus. Research conducted on November 2015 to January 2016. The method used in this research were extraction by maceration, fractionation by liquid fractionation, antibacterial activity test, and determination of minimum inhibitory concentration with the diffusion method and isolation of active compounds by column chromatography method. The bacteria used in this test are Escherichia coli and Staphylococcus aureus. Data are presented in tabular form based on the average value of the inhibition diameter and deviation standard. The results of this research showed the water methanol active fraction against the bacteria that used in this test. The methanol water fraction had obtained one antibacterial compound in bottle 1,3,5 which shows the value of tannin Rf 0,416. The minimum inhibitory concentration of water methanol of water apple leaves is 1000 µg/mL for Escherichia coli and 500 µg/mL for  Staphylococcus aureus. The minimum  inhibitory concentration of the active  compound  to  Escherichia  coli  and  Staphylococcus  aureus  in  500  µg/mL.  The fraction and the active compound of water apple leaves have an antibacterial activity with Escherichia coli and Staphylococcus aureus and the active compound is tannin.

Abstract

The research on the effect of architectural tree model to the noise level of motor vehicles on Demang Lebar Daun Street Palembang has been conducted. The purpose of this study was to analyze kind of architectural tree model can reduce the highest noise levels among the architectural tree models encountered and identify the architectural tree model. The method used was purposive sampling. Measurement of the noise level and architectural models were selected according to the type of the tree encountered on the left or right side of the street. The noise level measurement during the daylight was carried out simultaneously at a point of 1 meter in front of the tree, 1 and 5 meters behind the tree,for 10 minutes with the readings for every 5 seconds at 07:00, 10:00, 15:00 and 20:00. The results showed that The architectural model of Switenia magahoni tree was Rauh model, Lagerstroemia sp. tree was Troll model and Thyrsostachys siamensis tree was McClure model. The highest noise level reduction was from bamboo tree, respectively by 4,88 dB (A) and 8,52 dB (A) at the distances of 1 and 5 m. Keywords: noise level, reduction, architectural tree model
