Abstract

One of Freshwater Biology course problems is that the students were unable to understand the environmental phenomena around them. The aim of this study was to develop issue-based teaching materials in Freshwater Biology course to improve the students’ understanding about the environmental phenomena through their learning outcomes. This research and development used three phases of the 4D model developed by Thiagarajan, namely define, design, and development. The development results were validated by content and media experts. The design used for pilot test, which was conducted among 20 students, was one group pretest-posttest design; meanwhile the data analysis technique used was independent t-test. It can be concluded that the teaching materials developed was valid with the average validation score as high as 79.83%. In addition, there was significant improvement (sig. 0.000) of student learning outcomes after attending the course which implementing the issue-based teaching materials developed. Thus, the implementation of issue-based teaching materials is recommended in Freshwater Biology course due to its potential in improving students’ learning outcomes.

Abstract

Test organism which is used for bioassay must fulfill some criteria such as: high sensitifity, widely available, wide distribution, biology background, successfully maintained in laboratory, and known history of culture in laboratory. This research has been done to study regeneration (vegetative) process of Planaria under laboratory condition. This is studied because of limited number of planaria population in clean freshwater. In order to study regeneration process, combination of two treatments (water conductivity and division-cutting type) were done to obtain optimum culture of Planaria. Four water conductivity (100, 200, 300 and 400 μS/cm) and four division-cutting types (whole longitudinal, half longitudinal, transversal above pharynx and transversal mid-pharinx) were used. Each individual of Planaria was exposed with those treatments for 10 days (October, 2002). Initial and completed growth were observed. The result showed that, regeneration process of Planaria took 3-6 days to get full growth after transversal cutting (mid-pharynx). Whole summary revelead that Planaria is easy to maintain in laboratory. Therefore, Planaria may be used as an alternative bioindicator in evaluating water pollution.

Abstract

This study aims to develop e-modules based on the local Cirebon environment related to environmental changes that occur in the Cirebon region as a source of high school student learning to foster the eco-literacy of the student. The method in this research used to research and development (R&D) with the ADDIE model (analysis, design, development or production, implementation or delivery and evaluations). Data collection was conducted through observation, interviews, questionnaires, tests, and documentation. The development of e-modules was validated aspects of eligibility by material experts, technology experts, and users as measured by the validation sheet as well as student responses regarding the emodules as measured by a questionnaire. Meanwhile, the readability test given to students is carried out to ensure the quality of the e-modules as measured by the cloze test. In addition, the eco-literacy of the student was measured by an attitude questionnaire to find out how students' awareness and concern for the surrounding environment. Data were analyzed by qualitative methods. The results showed: 1) the feasibility of the e-module based on the validation of the material experts obtained 95.68% with a very good category, the validation of technology experts with a percentage of 72% categorized as good, and the validation of the teacher, as a user, showed a percentage of 75% with a good category, 2) the results of the cloze test analysis show that e-module has a high level of readability with a percentage of 92.46%, 3) student responses regarding e-modules obtained a percentage of 78.8% with a good category, 4) eco-literacy of students are shown by the results of questionnaire obtained an index of 4.04 with a high category. Products have been revised based on suggestions and corrections from validators and limited trial results. E-module based on the Cirebon local environment in fostering eco-literacy of students can be implemented in classroom learning

Abstract

Planaria sp. in Bukit Tunggul (Lembang) is rare within 10 years. This animal is sensitive to polluted water. Beside that, the number of this animal is decreasing due to alteration of landuse and climate change. This animal plays an important role as a bioindicator for clean water and as a media in learning of biology in high school as well as in university. Due to these need, study on ecology and distribution of Planaria sp. is done in Panaruban water fall, Subang. The sampling location is limited only at Cimuja, Karembong, Sawer and Goa Badak, which have an environment characteristics variation. Observations are done including water quality chemically, land use, and climatic factors within 3 times monthly. Planaria sp. counting is done stratified random sampling using a 1x1 m quadran. The number and biomass of Planaria sp. related to climatic factors are discussed. In general, it can be concluded that, abiotic environmental factors contributes to the abundance and biomass of Planaria sp.
