Abstract

Pahawang Island is one of Lampung's tourist attractions known for its high organism biodiversity. The diversity of coral reefs contained in it causes Pahawang to have economic value for the audience. This study aims to determine the coverage and condition of coral reefs in the Pahawang area as a tourist attraction and identify the diversity of organisms within. This study used the Line Intercept Transect (LIT) method by dividing the plot of the observation area by six (6) identification points for data collection. Measurement data on each line transect, furthermore the closing value is calculated. The number of species was calculated by determining the value of the invertebrate diversity index. The results showed that the length of coral cover on Pahawang Island was 80.3% which lies in the “very good” category. Most of the corals have experienced bleaching which suggests that the corals are not in healthy condition. Species diversity shows that eleven (11) species reside in the Pahawang Island coral reef. The Shanon-Wiener diversity index value (H') 1.87 is categorized at the medium level. Therefore, the condition of coral cover on Pahawang Besar Island is still in the very good category.

Abstract

The transition of the process of teaching and learning activities from face-to-face learning systems to online learning systems certainly provides significant changes. Online learning requires students to be more active in learning activities because teachers cannot monitor their learning process directly. This study aims to determine teacher and student perceptions, self-efficacy, concept mastery, and the interrelation between self-efficacy and conceptual mastery students of class X MIPA in online learning. The design used is descriptive quantitative with a correlational approach. The research sample consisted of 3 biology teachers and 118 students of class X MIPA SMA Negeri 1 Seputih Surabaya which were sampled from the population using total sampling technique. The research was carried out in June of the even semester of 2021. Quantitative data in the form of mastery of class X students' concepts of environmental change were obtained using questions, while qualitative data in the form of teacher perceptions, student perceptions, and student self-efficacy used a questionnaire in the form of google form. Data on perception, self-efficacy and concept mastery were analyzed descriptively, while the correlation between self-efficacy and concept mastery was analyzed inferentially with Product Moment. The results showed that the teacher's perception was categorized as good (67.28%). Students' perceptions are categorized as good (69.71%). Self-efficacy of students in the high category (67.87%). Mastery of concepts in the high category (39%). There is a positive relationship between self-efficacy and mastery concept of class X MIPA SMA Negeri 1 Seputih Surabaya with a low degree of relationship. DOI: http://dx.doi.org/10.23960/jbt.v11.i1.27394

Abstract

Mathematical representation and connection ability are part of the student's ability. Because of their low ability, educators will find it difficult to determine learning tools in the classroom. Therefore, finding a link between the two abilities is necessary to make it easier for teachers to prepare lessons. This study aims to determine the relationship between representational abilities and students' mathematical connections. The population in this study were all grade eight students at a state junior high school in Merbau Mataram, with a total sample of 34 selected using a class random sampling technique. The research instrument was a mathematical representation test and a connection ability test with a total of six questions. Data analysis used the correlation coefficient test of the Pearson/Product Moment formula. The results showed a significant relationship between students' mathematical representation ability and the overall connection. This means that the ability of mathematical representation is directly proportional to the ability of mathematical connections. The higher the student's mathematical representation ability, the higher the student's connection ability, and vice versa. Teachers can focus on preparing learning tools for one of these two abilities.

Abstract

Mathematical representation ability is an essential skill for students to understand mathematical concepts. Many studies have been conducted regarding this ability, but it is necessary to map existing research to provide a clearer picture of future research topics. This study aims to provide a bibliometric review of trends using mathematical representation skills in mathematics teaching research. The method in this study is bibliometric analysis, which aims to analyze and classify bibliographic material by presenting representative summaries of the literature in the Scopus database. The search was carried out using the keyword "mathematical representation" and selecting "article title" in the search menu in the Scopus.com database. Perish or Publish (PoP) software analyzes the author's name, number of document citations, document title, year of publication, document source, publisher, and document type. The results showed 99 publications and 357 citations related to mathematical representations, where the number of publications and citations fluctuated. The application of learning models and approaches, computer media, and analysis of mathematical representations is a research trend related to this variable. Therefore, paying attention to mathematical representations in learning mathematics and using effective strategies to improve students' mathematical representation abilities is essential. The findings of this study indicate the need to develop syntax and learning media based on mathematical representations to strengthen students' mathematical abilities.

Abstract

Science subjects in junior high school contain concepts from three different disciplines, namely Biology, Physics, and Chemistry, so that these subjects are taught by three different teachers. Even though the concept of science should not be compartmentalized, but must be able to complement one another. Likewise with the skills that must be taught in accordance with the demands of Basic Competence in the curriculum. The purpose of this service activity is to increase teacher professionalism, especially in teaching aspects, especially science subjects. The target for the training is science teachers at junior high schools in Pesawaran district. There are several training methods used, namely: need assessment, information discussion, assignment method, workshops on making integrated science lesson plans, presentations, discussions and information exploration, peer teaching at the MGMP. Improvement data was measured using a questionnaire instrument, essay test questions, the Teacher Performance Analysis test instrument (APKG) given before and after treatment, and peer teaching observation sheets (with MGMP). Data on increasing professionalism will be analyzed descriptively and using the t-test. The conclusions of the implementation of the integrated science learning model implementation training are: 1) The integrated science learning model implementation training is capable of increasing teacher professionalism in the aspects of knowledge, aspects of personality and social aspects. And the highest increase occurred in the social and personality aspects. 2) Increasing the ability to make an integrated RPP IPA less significant.
