IDENTIFIKASI DAN PREVALENSI CACING USUS PADA MURID SDN 2 SALOYA KECAMATAN SINDUE TOMBUSABORA SULAWESI TENGAH

Intestinal worm disease is still a public health problem in Indonesia. This disease can be found in children under five until fourthen years old. The aim of the present study was to prevalence of intestinal worm infection in children. The fresh faecal samples were collected from 56 childrens and observed by a Kato-Katz technique. The faecal of childrens were collected in SDN 2 Saloya village, Central Sulawesi. The result of identification on intestinal worm showed that 23 samples (41.07%) were found positive infections and 33 samples (58.93%) were found negetive infections. The prevelence of intestinal worm in class two were highest than all of them class. The prevalence of intestinal worm in females were highest than male. The totality sample identification of faecal childrens to Kato-Katz technique were found two genera i.e Trichuris, Ascaris, and other worm.Keywords: Intestinal worm prevalence, children

Effectiveness of Dung Beetles as Bioindicators of Environmental Changes in Land-use Gradient in Sulawesi, Indonesia

Bioindicators have been widely accepted as useful tools for monitoring and detecting changes in the environment or habitat condition. By using bioindicators, it is possible to assess the impact of human activities on the biota, instead of examining the entire biota. In this paper we analyzed diversity of dung beetles (Coleoptera: Scarabaeidae) across land use gradient inCentral Sulawesi and tested the suitability of dung beetles as bioindicators for environmental changes. Ninety baited pitfall trapswere placed and several habitat parameterswere measured at five land-use types ranging from natural forest to cacao agroforestry systems to open areas in 2009 and 2012. The effectiveness of dung beetles as bioindicators of environmental changes was evaluated by the IndVal method, a method combining the specificity and fidelity of certain species with particular types of habitat or environmental conditions. Surprisingly, the results showed that the diversity of dung beetles in two types of cacao plantations were similar to the forest sites and were significantly higher than the open cultivated area. Of the 16 dung beetles species analyzed only four species could be suggested as indicator (characteristic) species while the majority of collected species were categorized as detector species. Two of them (Copris saundersi and Onthophagus forsteni) were associated with natural forest and cacao agroforestry system, thus were suggested as the indicator of shaded and cooler habitats whereas O. limbatus and O. trituber can be suggested as indicator of unshaded and warmer habitats (bare land area).Keywords: bioindicators, diversity, Scarabaeidae, habitat preferences, IndVal

Aplikasi Ilmu Biologi Dalam Pendidikan dan Pembangunan Berwawasan Lingkungan Berbasis Sumberdaya Alam

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

Penggunaan Active Learning Tipe Card Sort Terhadap Hasil Belajar Biologi

This research aims to determine the effect of using card sort type active learning on Biology learning outcomes for class X SMA N 1 Palembayan students. This type of research uses a quassy experiment. The population in this study was 60 students. Sampling was carried out using a purposive sampling technique so that class X.1 was obtained as the experimental class and X.2 as the control class. The research instrument is an objective test consisting of 35 questions. The research results show that the data processing of the final test results is calculated using the t-test with the test criteria of accepting Ho if tcount<ttable and accepting H1 if tcount>ttable. From data analysis, it is obtained that tcount= 2.07 and ttable for the 1-α probability is 1.68, because tcount > ttable. In conclusion, there is a significant positive influence from the use of card sort type active learning on Biology learning outcomes for class X SMA N 1 Palembayan students. Keywords: Biology Learning Results, Use of Card Sort Type Active Learnin

Studi Komunitas Zooplankton Sebagai Gambaran Kualitas Perairan di Teluk Palu Sulawesi Tengah

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.
