Abstract

Analisis struktur dan komposisi vegetasi area reklamasi kawasan pengendapan tailing PT. Freeport Indonesia (PT-FI) dapat menggambarkan keanekaragaman,kelimpahan dan dominansi jenis. Informasi ini dapat dijadikan acuan untuk memantaukeberhasilan reklamasi yang dilakukan PT-FI sehingga akan membantu dalammengambil kebijakan pengelolaan kawasan pengendapan tailing. Monitoring vegetasidilakukan melalui metode observasi lapangan pada dua area reklamasi, yaitu area Tanggul Barat Lama dan area Tanggul Barat Baru di wilayah Mod-ADA. Datavegetasi meliputi tingkat petumbuhan semai, pancang, tiang dan pohon diperolehmelalui metode transek berupa garis berpetak. Diagram profil vegetasi digambarkanmelalui transek 20 x 60 m. Selama periode penelitian bulan Mei s/d Juli 2009, untukarea Tanggul Barat Lama diperoleh spesies tingkat pohon, tiang, pancang, semai setatumbuhan bawah masing-masing sebanyak 5, 8, 24 dan 51 spesies, sedangkan untukarea Tanggul Barat Baru masing-masing diperoleh 3, 3, 13 dan 38 spesies. Diagramprofil vegetasi untuk area Tanggul Barat Lama terdiri dari 11 spesies sedangkan untukTanggul Barat Baru terdiri dari 6 spesies. Diagram profil pada kedua tanggul inididominasi oleh Casuarina equisetifolia L. Hasil yang diperoleh menunjukkan areareklamasi yang pada awalnya hanya ditanami beberapa jenis tumbuhan sepertiCasuarina equesetifolia L., ternyata dapat menyediakan habitat yang cukup baik bagiberagam jenis tumbuhan lain.

Abstract

One example of marginal land is land mined and sandy soil. This land tends to be difficult to overgrow vegetation. Environment 19 Mile is part of the ModADA or Ajkwa watershed that has been modified as a PTFI tailing deposition area. The effect of high natural erosion and transport of mineral soils during the tailings drainage process causes soil structure in ModADA, especially in the double dike area to form faster, and allow natural vegetation. Characteristics of succession in the area were observed by vegetation profiles. The combination of making transects and sampling plots was used as a method for observing characteristic vegetation in the double dike area. The results showed that based on differences in vegetation height and canopy area there were 3 layers of vegetation, namely A, B, and C in the Double levees with flooded or tend to dry area. In the flooded area, Paraserianthes afalcataria and Timonius timon were dominated by an average plant height of 17.33 m; and layer B is dominated by Pandanus lauterbachii with an average plant height of 6.83m. In areas that tend to be dry, layer A species is dominated by Timonius Timon, Ficus armiti Miq, Glochidion macrocarpa, and Sterculia sp with an average plant height of 14.75 m; while layer B is dominated by Casuarina equisetifolia, Ficus armiti King, Ficus armiti Miq, Glochidion macrocarpa, Antiaris sp, Macaranga aleuroitoides, and Campnosperma brevi petiolata with an average plant height of 8.39 m. Layer C is in both types of soil occupied by species Phragmites karka. The vegetation profile shows that the area is an area with double dikes in the early stages of succession. This proves that this region is able to develop into natural revegetation of ModADA and accelerated through reclamation

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

Abstract

Despite high attention and commitment of Indonesia in biodiversity conservation and its habitat, however, loss of biodiversity and habitat deforestation is also still high. Deforestation rate in Indonesia between period of 2000-2012 reach up 6.02 million ha, and approximately onethird of which is in Sumatra Island. As the fulfillment of CBD and Aichi targets, and in line with the mandate of the Law on the Conservation of Natural Resources and Ecosystems and IBSAP (Indonesian Biodiversity Strategy & Action Plan 2015-2020), we try to support the requires data as well as information on the current state of biodiversity. The aims are to develop an inventory system of biodiversity needed to establish baseline data on biodiversity including its conservation status in South Sumatra, develop a biodiversity monitoring system with qualitative parameters that can be used in the determination and monitoring of degradation rates of biodiversity, and the establishment of data management system and information network of fauna biodiversity in South Sumatera so that it can be utilized in monitoring and reporting of biodiversity at regional, national and international level at the international level. We conduct a comprehensive review of methods and techniques of inventory and monitoring of fauna biodiversity, especially those that have been done in the area of South Sumatra Province. We also analysis of data needs and information network of fauna biodiversity in South Sumatra. The results is shows in the web-application database, called the South Sumatran Biodiversity Information Networks, or SSBIN, and could preview at http://ssbin.unsri.ac.id/.Keywords: south sumatra, biodiversity, information, networks, SSBIN.

Abstract

A research to monitor the presence of Sumatran elephant between two ecosystem in Sembilang National Park (TNSTNS) and palm palm oilplantation has been conducted on March until June 2019 at Semenanjung Banyuasin Semenanjung, South Sumatra. This research aimed to verify the presence of Sumatran elephantpopulation and to estimate the number of elephant individuals in the area. The methods used weredirect observation during the day and indirect monitoring through installation of Camera Traps for 1 month. In addition, secondary data was collected in the form of data archives from the palm oil plantation records and interviews with affected plantation workers. From direct observation, Wedirect encountered one elephant individual and fifteen signs of elephant activities, such as sounds, footprints, and feces. From camera trap photos, we identified and verified onepopulation of Sumatran Elephants which consisted of at least twenty-two individuals with composition as follows: eight adult females, two young females, three infant females, and nine males. The ecotone area between TNS and palm palm oil plantation should be designated as a new habitat patchof Sumatran elephant that needs to be managed appropriately in order to maintain the designation of the area as a conservation area.

Abstract

Coal mining activities in South Sumatra are among others carried out by PT. Bukit Asam tbk, a coal company located in Tanjung Enim. The open pit/cast mining process has a negative impact on the environment, some of the impacts are land degradation, loss of vegetation, changes in microclimate and loss of biodiversity which includes diversity of flora and fauna, one of which is amphibians. One of the efforts to maintain and preserve environmental capabilities is to reclaim former mines. In accordance with Law No. 4 of 2009 concerning Mineral and Coal Mining requires mining companies to carry out reclamation and post-mining activities over the areas they cultivate. Reclamation-revegetation activities are efforts to improve microclimate conditions, improve soil fertility conditions. The recovery of environmental conditions is expected to bring back the wildlife that has been lost. The amphibian community is believed to be a bioindicator of the recovery of environmental conditions undergoing habitat changes. The research was carried out at the Bukit Asam coal mine reclamation area, Air laya site from February to March. The aim of the study was to see the types of amphibians found in the mine reclamation area. Sampling was carried out using the VES (Visual Enconter Survey) method. From the results obtained, there were 3 species from 2 members of the Order (Anura) and 2 members of the Family (Rinidae).
