Keanekaragaman jenis burung di hutan kota pekanbaru

Abstract: A bird is a wildlife which could be found almost in any vegetated environment. The existenceof a bird in one area is very important because it could affect the presence and distribution ofplant species. The research aims to identify species diversity, distribution of bird species,habitat and analyze the relationship of bird species diversity to habitat in urban forest,Pekanbaru Municipal. The research was held in Diponegoro Urban Forest, Arboretum ofForestry Training Hall and Arboretum of Lancang Kuning University. The research wasconducted from March to June, 2011. All bird data were collected using a point countmethod. The vegetation data collected included species, composition and structure byforming a plot measuring. It was found 45 species, 26 families and 10 orders of birds. Thebird species diversity indices (H’) varied between 2.85 and 3.29, the bird average indices (E)varied between 0.87 and 0.9 and species richness indices (R) between 4.67 and 6.70. Thevertical bird distribution was mostly the bird with the upper canopy (35%), middle canopy(34%) and the rest was lower canopy (16%) as well as ground surface (15%). It was alsofound 77 tree species of 30 families. The tree species diversity indices (H’) varied between2.06 and 3.23, the species average indices (E) was between 0.64 and 0.85 and speciesrichness indices (R) was between 4.29 and 7.29. the bird species diversity in Pekanbaruurban forest had a positive correlation to the urban forest making trees.

Neraca Air Di Perkebunan Kelapa Sawit Di Ppks Sub Unit Kalianta Kabun Riau

Abstract: The water system disruption caused by the oil palm has become the issue of the environment.Oil palm plantations rated as the cause of changes in groundwater conditions, for allegedlyusing so much water for growth and production. To clarify these issues will require researchto provide an overview of changes in the water table of oil palm plantations in terms of thewater balance of oil palm plantations. The result showed that the calculation of thepercentage of interception in stands of oil palm has a value of 21.23% of the rainfall.Evapotranspiration in palm oil plantations ranged 68.23-125.63 mm/month, with an averageof 92.05 mm/month or 1104.5 mm/year. The water requirement of oil palm plantations issmaller when compared to the water needs of coconut trees and forest plants such as pine,acacia, segon, rubber and teak.

Current Trends In Seagrass Research In Indonesia (2010-2020)

Abstract: Seagrass is a higher plant (Anthophyta) that lives and grows immersed in the marine environment. Seagrass provides important ecosystem services include coastal protection, carbon absorption for climate change mitigation, nutrient storage for eutrophication mitigation and shelter for small fish, and high biodiversity conservation efforts for iconic endangered species. The current lack of global attention, therefore seagrass research is important to increase knowledge on a local and national scale. Given the extent of seagrass beds and the length of Indonesia's coastline which ranges 95,181 km, so it still needs to understand seagrass more deeply, because this is very important for conservation and restoration. The purpose of this review article is to comprehensively review research on seagrass in Indonesia in five years that expected to provide a future perspective for seagrass research in Indonesia. In the publication regarding seagrass studies in Indonesia, there are 7 categories of topics discussed, distribution and biology, plant physiology, microbial ecology, fauna, impacts and potential, carbon absorption, and restoration. In general, the focus on seagrass research in Indonesia includes seagrass species, seagrass communities, nutrient cycles in seagrass ecosystems, physiology, and the impact of pollution on seagrass habitats. The results presented in seagrass research in Indonesia are still quite descriptive and lagging when compared to studies that have been carried out in developed countries. The developed countries have developed new methods for seagrass restoration activities to new knowledge about seagrass genetics that has never been disclosed previously.

Abstract: The purpose of this study is to know the potential diversity of wild fauna (birds, butterflies, reptils , and mammals) in THAL. Inventory of mammal, reptile , and butterfly using line transect method while birds were observed by Ponctuels d'Abundance Indices method (IPA ). The results showed that the potential fauna can be found in THAL as many as 49 species consisting of 36 species of birds, eight species of butterflies, three species of reptiles , and three species of mammals. From 49 fauna species at least nine species were endemic to Sulawesi and 11 species protected by Indonesian law. In the future development of THAL area, it is expected that management will conserve the condition of wildlife habitat in order to stay natural.

Analysis of suitability and carrying capacity of mangrove ecosystem for ecotourism in Lembar Village, West Lombok District, Indonesia.

Abstract: . Sukuryadi, Harahab N, Primyastanto M, Semedi B. 2020. Analysis of suitability and carrying capacity of mangrove ecosystem for ecotourism in Lembar Village, West Lombok District, Indonesia. Biodiversitas 21: 596-604. Mangrove ecosystems in Lembar Village, West Lombok District, Indonesia has high ecological role and economic potentials, and have been as a pilot area for mangrove conservation and rehabilitation activities. In 2015 the area was developed into a mangrove ecotourism area as a form of utilization to obtain ecological and economic sustainability for the local community. The purpose of this study was to determine the suitability and carrying capacity of the mangroves area for the development of mangrove ecotourism. Data collection was conducted using field surveys and direct observation. Data collected were then analyzed to calculate ecotourism suitability index and carrying capacity of the area. The results of data analysis showed that mangrove ecosystem area in Lembar Village is categorized as suitable to be developed as mangrove ecotourism at three stations with value of ecotourism suitability index of 77.78%, while at two stations are categorized conditionally suitable with ecotourism suitability index of 42.22%. Carrying capacity of the area is 2337 people/day with tourist attractions consisting of mangrove tracking (33 people/day), fishing (137 people/day), picnic (1620 people/day), camping ground (542 people/day) and bird watching (6 people/day). Utilization of area based on suitability and carrying capacity is needed to maintain the sustainability of mangrove ecosystems and the economy of coastal communities.

Dampak Ekonomi dan Lingkungan Ekspansi Perkebunan Kelapa Sawit (Studi Kasus: Desa Penyabungan, Kecamatan Merlung, Kabupaten Tanjung Jabung Barat, Jambi)

Abstract: Oil palm is one of the major plantation commodity that earns foreign exchange. The expansion of oil palm plantation potentially gives not only economic benefits, but also the environmental problems. Therefore, the economic and environmental impacts of oil palm plantation expansion need to be assessed. This study uses revenue analysis to estimate the economic benefits, descriptive analysis to identify environmental impacts, and to estimate external costs using replacement cost and cost of illness. In this research, expansion is defined as the conversion of a part of or whole rubber plantation to oil palm plantation. The expansion resulted in farmers turning some or all of rubber gardens into palm oil plantations that resulted in an increase in revenues of 40.52%. In addition to the on-farm sector, farmers benefit from off-farm (24.46%) and non-farm (25.61%), bringing the total increase of farmers' income by 33.42%. Based on community perceptions of environmental impacts due to oil palm plantation expansion in the form of reduced quantity of groundwater, water pollution, and decreased animal population. The environmental impact of crude palm oil (CPO) factories is to produce liquid waste from palm oil processing that raises external costs for the community in the form of the replacement cost of clean water and the cost of illness
