Abstract

Telah  dilaksanakan  Penelitian  mengenai  Coleoptera  di  Kawasan  Taman  Hutan  Lindung Paneki  Kabupaten  Donggala  dengan   bertujuan  untuk  mengetahui  Coleoptera  yang  terdapat  di kawasan Taman Hutan Lindung Paneki. Metode penelitian yang digunakan dalam penelitia ini adalah metode  Deskriptif  dengan  teknik  pengambilan  sampel  menggunakan  perangkap  Barber  yang dipasang pada transek berpetak dengan jarak atar plot 10 m. Populasi dalam penelitian ini adalah semua Coleoptera yang ada di kawasan Taman Hutan Lindung Paneki, sedangkan yang menjadi sampel   dalam  penelitia  ini   adalah   keseluruhan  individu   Coleoptera   yang  terperangkap   pada perangkap  Barber.  Dari  hasil  pengidentifikasian  ditemukan  Coleoptera   sebanyak  9  famili,  yaitu: Cucurjidae (129,66) selanjutnya diikuti oleh  Scarabaeidae (107,66), Scolytidae (32), Melyridae (23), Stapphylinidae (17),  Silphidae (15,33), Buprestidae (7), Cleridae (2), dan   Lathridae (1,33).Kata Kunci: Coleoptera permukaan tanah , Taman Hutan Lindung Panek

Abstract

This study aims to evaluate the effect of forest conversion to agriculture, especially cocoa plantation on spider diversity in Central Sulawesi. The experiment was conducted in the vicinity of the village of Bobo Palolo Subdistrict, Donggala in the margins of Lore Lindu National Park in Central Sulawesi. Spiders were collected on transects size of 50 mx 10 m at each study site using insect nets. The results showed that there are at least 17 species from 11 families of spiders recorded from natural forest, disturb forest, and cacao plantation. Changes in habitat type affect the diversity of spiders. Spider species diversity tends to decline due to habitat change from natural forest to cocoa plantations. However the forest with intermediate level of disturbance as well as a cacao plantation that maintains many types of shade trees has capability for supporting spiders diversity. Community structure of spiders at the cacao plantation are relatively similar to those in natural forests.

Abstract

Biology is one of knowledge belong to basic sciences that have important roles in education and sustainable development that environmental sound. Biological science is a basic for numeral applied sciences such as Medicine, Pharmacy, Agriculture including Fishery, Animal husbandry, Forestry and soon. There is a branch of biology which have been developed rapidly namely Ecology that close related with environmental problem or sciences that study on the relationship between organism and their environment or interaction among environmental factors at a numerous ecosystem type such teresterial, fresh water, marine, forest and soon. Ecology is the study that may explain the cause of the occurrence of various phenomena and environmental issues that occur on Earth, such as floods, drought, landslides, the "algae blooming”, "silent spring", the development of infectious diseases, emergence of strange diseases like cancer caused by xenobiotics compounds, global warming, acid rain, destruction of biodiversity, etc. Key words: Biology, environmental sound development , ecology, natural resources.

Abstract

The research to measure of mercury accumulated mercury at spesies Gastropods, (fresh water sanils) in Poboya stream have been conducted from March to May 2012. Snail were collected by “Hands Picking” technique at 4 station with Purpose Random that were based on population density. Snails were became to analysis Lymneae rubiginosa M that founded at station 1,2, and 3., Melanoides torulosa B and Melanoides tuberculatus L that founded at station 4. The result of mesuare of mercury accumulated showed that it’s station and kind snails spesies in station 4 were different. The high consentration found at Melanoides torulosa B in station 4 were 0,09 ppm, and then followed by Melanoides tuberculatus L. in station 4 were 0,06 ppm, Lymneae rubiginosa in station 3 and 1were 0,05 ppm, and the low consentation mercury at Lymneae rubiginosa M. in station 2 were 0,02 ppm. Key words: Gastropods, bioaccumulator, Merkury, Poboya stream

Abstract

Research of the "Study Zooplankton Community As Overview Water Quality of Central Sulawesi in Palu Bay" was conducted from March to May 2012. This research was aimed to Determine the structure of zooplankton community in waters bay of Palu. Samples were taken vertically and horizontally by using a plankton net and Lamotte water sampling at four research stations, they are: Station 1 in the area of the river mouth of Palu, station 2 in the area of Tondo village settlements, station 3 in the areas of sand mining and quarrying C Taipa, and station 4 in the area of PLTU. Samples were observed and analyzed in the laboratory of the Department of Environmental Biology Faculty of Mathematics and Natural Sciences. The results showed that in the bay Palu found three phyla, 3 classes, 7 orders of zooplankton are classified into 30 types. The results of the analysis of the diversity index (H ') ranged from 0.69 to 2.61 belong to the diversity of medium and low. Uniformity index (E) ranged from 0.60 to 1.00, belonging to the high uniformity. Total abundance at the surface ranged from 0.12 to 3.60 ind / l. Total abundance at depths ranging from 30-490 ind / l. Key words: Community, zooplankton, water quality, the bay of Palu
