Abstract

Tujuan penelitian ini adalah: (1) mengembangkan instrumen tes diagnostik three-tier yang digunakan untuk analisis dan mengidentifikasi miskonsepsi siswa di sekolah, (2) menerapkan hasil tes sebagai dasar identifikasi faktor miskonsepsi, dan (3) merumuskan model pembelajaran remedial untuk meremediasi miskonsepsi. Penelitian ini dirancang sebagai penelitian R&D dengan model 4D, yaitu define, design, develop dan disseminate. Dalam penelitian ini dilakukan sampai tahap develop. Hasil uji kelayakan instrumen menunjukkan bahwa validitas isi termasuk kategori layak dengan reliabilitas 0,58. Tingkat kesulitan tinggi untuk pertanyaan 4 dan 5 sementara yang lainnya tergolong sedang, dan nilai daya beda (D) > 0,20. Selanjutnya, ikatan kovalen menunjukkan persentase miskonsepsi yang paling tinggi (26,29%), sedangkan bentuk molekul menunjukkan persentase terkecil (8,74%). Dapat diidentifikasi bahwa faktor yang menyebabkan kesalahpahaman adalah metode pembelajaran yang tidak tepat dan konsepsi awal siswa. Hasil dari formula pembelajaran remedial untuk mengatasi miskonsepsi siswa adalah pembelajaran conceptual change. Hasil ini menunjukkan bahwa hasil analisis miskonsepsi dapat digunakan untuk mengembangkan program pembelajaran remedial yang dapat memperbaiki miskonsepsi siswa. The consecutive aims of the research were to develop the three-tier diagnostic test instrument used for analysis and identify the students` misconception, to apply the test results for underlying the misconception factors, and to formulate remedial learning models for remediating misconceptions. The research was designed as method of R&D with 4D model, define, design, develop and disseminate. In this research is done until develop stage. The results of instrument feasibility test shows that the validity of the contents is categorized as feasible with reliability of 0.58. The difficulty level of are high for question #4 and #5 while the other classified as moderate with items discrimination value (D) > 0.20. In advance, the kovalen bond shows the highest misconception percentage (26.29%), while the molecular shape shows the smallest percentage (8.74%). It can be identified that factors causing misconceptions are inappropriate learning methods and early conceptions of students. Then, the result of remedial learning formulae for overcoming students` misconception is conceptual change learning. These results suggest that the results of misconception analysis can be used to develop a remedial learning program that can remediate students` misconceptions.

Abstract

The Pulokerto region has been planned for agrocity tourism by the Palembang City Government. The changing function of these areas givesome effects to quality of water and biota around the river. The aims of this research is to study of macrozoobenthos structure communityas biomonitoring instrument. The research was conducted during September until December 2010. The location sampling was determinedby purpossive random sampling method in 8 stations. The sampling in the moody area was carried out by Eckman grab. The results showedthat 14 genera have been classified into 5 classes such as Oligochaeta, Gastropoda, Insecta, Bivalvia and Crustacea. Population og. generais in around 75-600 ind/m 2. Diversity index is low until moderate with value 0.27-0.74 and there is no domination of species in thecommunity. The cluster analysis showed that 2 community groups of macrozoobenthos have relation with population of individu tophysicochemical quality of water. The overall study shows the balancing of community in the Pulokerto region but still susceptible topressure effect of environment.

Abstract

This study aims to develop a five-tier form of fluid misconception diagnostic assessment and to reveal the profile of student’s conceptual understanding in maritime-based schools in the city of Tegal. This study used a 4D model (defining, designing, developing, and disseminating). The sampling technique used purposive sampling. The research samples were Bahari Vocational School Tegal, Al Maarif Vocational School Tegal, and Nahdlatul Ulama Senior High School Tegal. Methods of data collection used documentation, questionnaires, tests, and interviews. Expert validation states that the instrument was valid, has good readability, was easy to understand, and the sentence structure was correct. The reliability of the instrument is 0.958 and declared reliable. A total of 39 questions were categorized as medium, and one question was easy. The discrimination power of the questions obtained was that 30 questions were accepted, eight questions were received with a little improvement, and one question needed improvement. Seventy student misconceptions were identified from seven fluid sub-concepts. The biggest misconception, as much as 46.5% was found in the buoyancy sub-concept, while the smallest misconception was found in the application of Pascal's law at 35.2%. The most dominant misconception is that the deeper a point in the fluid is, the greater the buoyancy. Students assume that the greater the depth, the greater the fluid pressure, so that the buoyancy force is greater. Students believe that buoyancy is influenced by fluid pressure. This misconception is influenced by conceptual appreciation and intuition in daily life.

Abstract

A rapid bird survey was done in a small conservation area of industrial timber concession of PT BMH (Bumi Mekar Hijau), namely KPPN (Kawasan Pelestarian Plasma Nutfah), South Sumatra Province. The area has 448 ha, dominated by degraded secondary swamp forest surrounded by Acacia plantation. Three survey methods were applied to assess bird diversity in this area: transect line, mist-netting and audio-visual station recording. A total of 36 species was recorded during survey. Among three methods applied, transect line is the most effective method to detect more bird species (29 species), followed by audio-visual station recording (26 species) and mist-netting (three species). There are eight species which protected by Indonesian law and two birds are listed as Near Threatened (NT) by International Union for Conservation of Nature or IUCN. Although number of species birds recorded are not significance, but this area still support habitat for various birds diversity, and the forest remaining should be well-managed to support its conservation goals.

Abstract

Research on Diversity and distribution of butterflies, was held at the Campus Indralaya Sriwijaya University of South Sumatra. The purpose of this study was to obtain information species diversity of butterflies at the Sriwijaya University of Inderalaya and distribution of species of butterflies in several different habitat types in the campus area Unsri Indralaya. The study used purposive and collection methods in November 2014-january 2015. Sampling sites were divided into five locations: Arboretum, Science Faculty, Faculty of Law, Faculty of Agriculture and Swamp Cape Disconnect. The parameters used are the index of species diversity, dominance index, and evenness index. The results showed that the diversity of butterflies in the region is classified as moderate. Overall found as many as 40 species of butterflies with a number of 609 individuals consisting of 5 the Papilionidae, Nymphalidae, Pieridae, Lycaenidae, and Hesperiidae. Regions Sriwijaya University has a diversity of butterflies that were moderate with criteria (H'1≤H'≤3), in each different habitat types, and not found butterfly species that dominate in every type of habitat in this Unsri region. Distribution of butterflies found in the campus area Unsri Indralaya categorized fairly evenly with a range of values from 0.58 to 0.68.Keywords: Butterflies,  Diversity,  Distribution , Sriwijaya University of Indralaya
