Oktiana D, Antono W. 2015. Diversity of birds in the neighborhood Indonesia Power Generating Unit (UP IP) Tambak Lorok, Semarang. Pros Sem Nas Biodiv Indon 1: 1045-1049. Birds are one of the components of the ecosystem that have interaction and interdependence with the environment, so the existence of birds in the ecosystem needs to be maintained. The objective of this research was to determine the diversity of bird species in the environment around Indonesia Tambak Lorok power plant, Semarang, Central Java. The investigation was made through survey and observation (census) in the area of Indonesia Tambak Lorok power plant. Two variables, namely: the number of species and the number of individual birds were monitored. The observation was conducted in 2013 and 2014. In 2013, 23 species of birds having Shannon-Wiener Diversity Index value of 2.713 were observed, while in 2014, 28 species of birds with Shannon-Wiener Diversity Index value 2.652 were observed. There has been increased of bird species within one year in the environment around Indonesia Tambak Lorok power plant, from 23 types to 28 types, However, the bird diversity index value has been decreased slightly due to the decline of Evenness index value. It happens because the presence of swallow Linchi (Collocalia linchi) was good enough and dominant in the year of 2014, whereas in 2013 was not found. Attention and cooperation are required to make Indonesia Power Tambak Lorok plant environment more tangible so that this power plant becomes a comfortable and eco-friendly habitat for fauna including birds which are found around the area.
