Development of Plant Biosystematics E-Module Based on Problem Solving Sekar Jati Pamungkas; Wike Oktasari
Indonesian Journal of Biology Education Vol 3, No 2 (2020): INDONESIAN JOURNAL OF BIOLOGY EDUCATION
Publisher : Universitas Tidar

This study aims to describe the stages of developing the Plant Biosystematics e-module with the 4-D model (four D model) and to analyze the effectiveness of the resulting Plant Biosystematics e-module in improving problem solving skills in students of the Tidar University Biology Education Study Program. The Plant Biosystematics course studies the description, adaptation, and classification of plants, both high and low levels. The research method used is the R&D Model. This model consists of 4 development stages, namely Define, Design, Develop, and Disseminate. The object of this research was 60 students of Tidar University Biology Education. The research instrument used was in the form of questionnaires and validation sheets by the validator. Based on data on Problem Solving skills 38, 3% chose the number 5 meaning that in this Plant Biosystematics e-module all 5 indicators have been fulfilled. Based on the development of the e-module by the validator, the results of the material were 80.5%, the presentation aspect was 54%, the linguistic aspect was 24%, and the graphic aspect was 34%. Based on the data above, the development of the Plant Biosystematics e-module can be used as a learning module that can improve their problem solving skills.

Misconceptions are often experienced by the students of senior high school. Especially on the learning material of circulatory system. The aim of this study is to develop Biology instructional media in the form of Adobe Flash-based interactive instructional media on the learning material of Circulatory System which the content is designed to improve the students’ competencies. The development of this instructional media uses the RnD method with the Borg and Gall development model. There are 3 validators consisting of 2 Biology material experts and 1 instructional media expert who will test and validate the media that is developed. The study to test the effectiveness of the media is a before-after experimental design. The validation of media done by material and media experts shows the result that is categorized as very good, and the result of statistical test with paired sample t-test shows a significance value of 0.00 < 0.05. This means that there is a significant difference in the average score of students from before and after using Adobe Flash-based interactive instructional media to improve students’ competencies. Thus, the Adobe Flash-Based Interactive instructional media can improve the competencies of students.

Genetic Material Upgrading: Misconception Identification Study in High School Biology Teachers Ika Sukmawati; Karunia Galih Permadani

Publisher : Universitas Tidar

This study aims to identify and map patterns of genetic misconceptions in high school biology teachers. This research was conducted in several stages, including the development of diagnostic test instrument with Certainty of Response Index (CRI). The instrument used in measuring misconceptions in this study is a three-tier test diagnostic instrument. There are 20 questions covering Basic Competencies 3.3, 3.5, 3.6, 3.7, and 3.8. The cognitive level of the questions covers C2 to C5 in Bloom Taxonomy. The validator's assessment shows that the instrument is suitable for data collection. The results of data collection indicate that the topics identified as having misconceptions among high school teachers are quite high (above 50%), among others: (1) The relationship between DNA, genes, and chromosomes; (2) Chromosome structure of eukaryotic cells; (3) The process of protein synthesis (transcription, translation, and genetic code); (4) Mendel Law 1; (5) Mendel Law 2; (6) Crossing-Over, Sex-Linkage, and Non-Disjunction; and (7) Causes of Mutations. Apart from misconception data, this study also reveals the experiences of teachers in conducting Biology teaching and learning activities, especially related to Genetics in high school.

Measurement of alpha-Amilase Enzymes in Bacillus subtilis Bacteria Sukmawati Sukmawati; Melda Yunita; Febrianti Rosalina

Publisher : Universitas Tidar

The bacterium Bacillus subtilis is able to produce amylase enzymes which are able to hydrolyze various types of starch sources into simple compounds such as maltose, glucose. Amylase converts carbohydrates which are polysaccharides into maltose. Amylase enzyme is a group of enzymes that are needed in the industrial field. The purpose of this study was to determine the level of the amylase enzyme produced by the bacterium Bacillus subtilis. The method used in this research is a quantitative method using an amylase enzyme measurement experiment. The results of this study are from two types of enzyme sources, namely Bacillus subtilis + Starch + NB and Bacillus subtilis + NB. Both samples showed enzyme activity. The conclusion of this study is that Bacillus subtilis + Starch + NB produces 63.186 units of the alpha-amylase enzyme used to produce 1 ppm / 1 micromol maltose per minute. Whereas the Bacillus subtilis + NB sample was 19.474 units of the alpha-amylase enzyme used to produce 1 ppm / 1 micromol maltose per minute.

21st-Century Learning: Development of Respiradroid Media (Respiration Concept) For High School Students Nurhalimah Nurhalimah; Elsa Lisanti; Rizhal Hendi Ristanto
Indonesian Journal of Biology Education Vol 3, No 2 (2020): INDONESIAN JOURNAL OF BIOLOGY EDUCATION
Publisher : Universitas Tidar

This research is a research development that aims to develop biology learning media in the form of an android learning application. This study uses research and development (R&D) with a method developed by Thiagarajan, namely the 4D model with stages: define, design, develop and disseminate, the stages of this study are limited to the development stage. Products that have been developed are then validated by experts in their fields. The results showed that respiradroid learning media had an average of 3, 31 in aspects of learning media. The validation results obtained from media and material experts prove that respiradroid media developed are suitable for use in the learning process. Media respiradroid learning has the advantage that is, a learning media that is flexible means that it can be used anywhere, easy to install, easy to find material content with student stimulus for thinking. It is expected to improve students' higher-order thinking skills in the concept of respiration.

The Diversity of Pteridophyta at Mountain Telomoyo as Biology Learning Resources Muhammad Radian Nur Alamsyah; Sekar Jati Pamungkas
Indonesian Journal of Biology Education Vol 3, No 2 (2020): INDONESIAN JOURNAL OF BIOLOGY EDUCATION
Publisher : Universitas Tidar

The identification and utilization of pteridophyta diversity in the Telomoyo mountain area in learning activities has not been implemented. On the other hand, Biology as a science subject needs to be presented through scientific learning to encourage the development of students' science process skills. The type of learning resource by utilization is the right type to be used in scientific learning. These learning resources are found mainly in nature. Based on this, this study aims to identify the diversity of pteridophyta in Mount Telomoyo and to analyze their feasibility as a source of Biology learning at the high school. This study uses a descriptive exploratory method. The observation plot was determined to be 2 meters wide from the right and left side along the climbing route, using a purposive sampling technique. Analysis of learning resources using benchmarks by Djohar (1974). The results, there are 13 species of pteridophyta which can be classified into 12 genera, 10 families, 4 orders, and 2 divisions. Biology material that is appropriate for the application of learning resources is the Scope of Biology with a 75% suitability level. The results of the feasibility analysis of learning resources generally obtained a very feasible category (87%).
