The high value and economic prospects of precious metals, have not been able to cover the environmental, health and social and economic impacts. The conversion of land functions and open pit mining activities as well as the amount of sediment waste causes very significant landscape and environmental changes. This study aims to evaluate the impact of using mercury and cyanide based on the knowledge and experience of actors (miners and gold processors) and the surrounding community on the island of Lombok. Field data collection was carried out by triangulation, namely in-depth interviews with actors and the community, and secondary/reference data from related agencies, especially the health center and several related research results. Gold extraction on the island of Lombok uses two methods which are carried out in stages, namely Amalgamation with mercury in the shelling process and Cyanidation with Potassium Cyanide in the bagging process. The results of the study show that the negative impacts of the mining process are more due to land clearing and miner safety. The impact of gold extraction using mercury is long-term, so it is difficult to identify the impact. Meanwhile, the impact of the use of cyanide is directly felt and seen by the public, especially in terms of decreasing the presence and yield of fish caught in rivers and coasts.

City parks, apart from having an aesthetic function as a place for recreation, also have an ecological function with vegetation components to soften the microclimate. Vegetation analysis was carried out in six city parks in Mataram City to determine the vegetation structure. Microclimate factors of the park, namely light intensity, air temperature and humidity inside and outside the park during the day and observations of sound attenuation at night have been carried out. Climatic data is carried out to determine the park's ability to reduce heat and air temperature, increase air humidity and reduce noise and determine the park's environmental discomfort index. Of the six urban parks observed in the city of Mataram, namely the parks of Ampenan, Malomba, Udayana, Sangkareang, Mayura, and Selagalas, it is known that there are three groups of vegetation structures, namely trees-shrubs, shrubs-trees, and shrubs. Vegetation with various compositions of life forms in each city park only controls 40 to 60% of the land area of the park. Urban parks in Mataram City have a low level of ability to soften the microclimate, which is below 5%. In reducing heat and air temperature, and increasing air humidity. City parks are also known to have a low ability to reduce noise. The city parks of Ampenan, Udayana and Sangkareang have an environmental comfort level equivalent to the discomfort felt by more than 50% of the population, while the Malomba, Mayura, and Selagalas parks have a level of comfort equivalent to the discomfort felt by less than 50% of the population. The existence of urban park vegetation is only able to reduce the discomfort index of 7 to 9%.

Ornitholog past studies focused on the natural environment, now they have a lot of studying birds in urban areas. In Java inhabited by 368 species of birds recorded settler and nomad 126 species of birds , but it is not known how many types of them which now lives in urban areas. Bird diversity in the city of Yogyakarta, which was founded in 1755 and now has a population of 388 627 inhabitants, is unknown. The research objective was to determine the diversity, the proportion of community based on the type of bird feed (guild) and bird species nest in the city of Yogyakarta. The study was conducted during the day in April-May 2013 in the 7 villages of 3 subdistricts in the city center Kraton, Gondomanan and Ngampilan. Data colection used Point of Abundance Index method, and analyzed by the Shannon Diversity Index - Wienner ; types of feed directly observed and are determined based on a review of literature and the proportion of bird communities based on guild were analyzed with the use of modified importance value index ; nest observed directly and analyzed descriptively. The results showed in Yogyakarta were found 28 species of birds covered in 11 familia with moderate levels of diversity (diversity index 2.2) and 5 types including protected status that is Anthresep malacensis, Nectarinia jugularis and Arachnothera longirostra (Fam.Nectariniidae), Alcedo atthis and Halcyon cyanoventris (Fam. Alcedinidae). Composition based on the guild type is graminivorous (46.58 %), nectarivorous (46.51 %), nectrivoous (5.53 %), frugivorous (1.08 %), and 0.29 % piscivorous, and was found at least nine species of birds that nest in the city of Yogyakarta. Therefore, birds in the city of Yogyakarta is quite diverse and populated several protected species, it is necessary to research on biological properties, especially the origins, patterns of reproduction and structural adaptation and behavior.Keywords : City of Yogyakarta, birds, diversity index, type of feed, nest

Bali Myna (Leucopsar rothschildi) is Bali’s endemic bird. Their number is decreasing gradually in the wild (Balen et al., 2000). Its bright color of white feather and blue skin that surrounded its eye have made them easy to be hunted when it perched on abranch. Bali Myna was classified as endangered species by International Union of Conservation and Natural resources (IUCN) in 1977 (Whitten et al. 1999). There is a captive breeding in Tegal Bunder, Bali Barat National Park (BBNP) called Bali Myna Guidance Centre to increase wild population as an effort to prevent extinction. There, its conditions should be monitored regularly to keep them in prime condition, before being released for breeding purpose. Their condition could be controlled by monitoring their daily activities.
