Abstract

Lesson study was a practical approach to improve the quality of instruction and use widely in professional development programs for teachers. This article presents an innovative approach to developing the instruction ability and skills of science teacher candidates when actual teaching practice in a classroom through lesson study. Based on the lesson study approach, science teacher candidates worked collaboratively to understand the curriculum and state the desired learning outcomes; design lesson plans; teach a common lesson in 4 different classrooms; and conduct reflection to share, discuss, and refine their lesson. The teaching abilities and skills are assessed based on knowledge of the subject matter, quality of lesson plans, and learning practices. The result showed that the lesson study approach was a vital structure that helped science teacher candidates improve their teaching skills and ability. The research result gives implications for development programs for science teacher candidates will be discussed in light of these findings.

Abstract

The purpose of this study is to analyze the quality of optical properties such as energy band gap of thin layer of tin oxide doped with aluminum, tin oxide doped with fluorine, tin oxide doped with indium, tin oxide doped with aluminum-fluorine, tin oxide doped with aluminum-indium, and tin oxide doped with aluminum-fluorine-indium. The thin layer was synthesized using the sol-gel spin coating method. The ratio of basic ingredients and doping used in this study was 95:5% and 85:15%. The thin layer that has been formed is then heated at a temperature of 100 and 200 0C. The results of the analysis of optical properties showed that the largest values of direct and indirect energy band gap are in a thin layer of tin oxide doped with indium at a percentage of 95:5% for a temperature of 100 0C, namely 3.62 and 3.92 eV. The lowest values of direct and indirect energy band gap are in a thin layer of tin oxide doped with aluminum-fluorine-indium at a percentage of 85:15% for a temperature of 200 0C, namely 3.36 and 3.51 eV. These results indicate that the resulting energy band gap decreases with increasing doping concentration and sintering temperature. Based on the optical properties obtained, the thin layer can be used as the basic material for semiconductors in electronic devices.

Abstract

This study aims to determine the effect of black cumin seed extract (Nigella sativa) on body weight and mortality of broiler chickens. Broiler chickens were randomly selected to represent 4 dose groups: control group (P0), 1.5 ml/liter extract (PI), 2 ml/liter extract (PII), and 2.5 ml/liter extract (PIII). The treatment was given by mixing black cumin seed extract (Nigella sativa) into the drinking water of broiler chickens for 3 weeks. The variables observed included body weight and mortality of broiler chickens. Data analysis used the one way ANOVA test followed by the LSD (Least Significant Difference) test. The results showed that the higher the dose of black cumin seed extract (Nigella sativa) given, the greater the broiler weight gain, while the mortality rate did not show any effect on the dose given. It can be concluded from this study that black cumin seed extract (Nigella sativa) has a significant effect on weight gain, but has no effect on broiler mortality

Abstract

Lipase demand keeps increasing as it has wide applications in many sectors of industry, hence producing lipase is economically prospective. Finding a cheap medium is important for lipase production for commercial purpose. Waste based medium KIT1, KIT2 and KIT3 were alternately assessed for the capability to support growth and lipolytic activity of the fungi.  SDA either or PDA were used as the control Medium. Fungi isolated from Coconut or Avocado flesh were used. Observation was made on day 1 and day 2 after inoculation. The result suggests that KIT2 gave similar growth and lipolytic activity to SDA medium, and better growth and lipolytic activity on KIT3 medium as compare to SDA and PDA

Abstract

Coastal waters well known to provided large number of natural resources, but it recives some negative effects due to numerous ectivities take place on it, so it’s quality status tend to decrease. The coastal waters of Mandalika SEZ Central Lombok is no in exception. Microalgae as maind primery producent, have been much reported as bioindicator for controlling the waters quality. Study for community of microalgae as bioindicator in the coastal waters of Mandalika SEZ Central Lombok never been done. This study was conducted to observed and analyze the potency of microalgae community in the coastal waters of the Mandalika SEZ for determining the quality status that waters. Five bottles of 150 ml volume sea waters samples were collected using a free fall nylon plankton net of 20 πm mesh sized. Samples were preserved using formalin in final consentration of 4%. Samples were observed in both laboratories of Biology Education Faculty of Teacher Training and Education and Biology Science Faculty of Math and Science, University of Mataram. Data were analyzed for counting of density, percentage dominancy, and species diversity indexs. Total 72 species of microalgae were fully indentified and Chaetoceros didymum was a dominant species with percentage dominacy and density of 16.243% and 143.949 ind/L, respectively. The highest dencity was recorded in sample taken in the Seger Beach (1567.941 ind./L), then followed by the beaches of Gerupuk, Serinting, Mandalika, dan Kuta with density velue of 1469.214 ind./L, 1038.217 ind./L, 759.023 ind./L, and 622.081 ind./L, respectively. Based on the data of microalgae density, species diversity indexs, and number of taxa, the five sampling sites have high percentage similarity (83.336%). Species diversity index of microalgae in the coastal waters of the Mandalika SEZ was in intermediate category (H’=3.415). Based on the rerults of this study, mainly based on the velue of microalgae species diversity indexs, it can be concluded, that the quality status of coastal waters of Mandalika SEZ Central Lombok was in non polluted category

Abstract

This research aims to produce a student worksheet based on Science Process Skills (SPS) on the concept of the excretory system and to see the responses of teachers and students to the worksheet. The method used is Research and Development (R&D) with a 4D development model (Define, Design, Develop, Disseminate), which is modified into 3D (without Disseminate). The instruments used in this study included a checklist of student worksheets, interview sheets, content validity and readability test instruments for student worksheets, and teacher and student response questionnaires. The development process was through a validity test by three experts, a readability test by 12 students, and a field trial by one biology teacher and 90 students. The results showed that the developed worksheet had an average validity percentage of 85.40% with excellent criteria. In the readability test, the average percentage of the worksheet reached 92.01%, with excellent criteria as well. While in the field trial, the responses of teachers and students showed excellent criteria with percentages of 87.42% and 86.65%. Based on the results, it can be concluded that the Student Worksheet is very suitable to be used in learning activities

Abstract

Indonesia's scientific literacy ability is low with a score of 389. This score can indicate the critical thinking skills of junior high school students. To improve critical thinking can be done by innovating learning tools. For this reason, this research was conducted using the R&D method to develop UKBM which can help students achieve learning mastery. UKBM is part of the learning tools. In this study, UKBM was prepared based on Problem Based Learning (PBL) on the physics of the human circulatory system. So that it can be used by students in learning to enrich their knowledge by oriented towards critical thinking skills. The model used in this research is ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The research was conducted during the Covid-19 virus pandemic, so there has been no effectiveness test. The validity of UKBM was obtained through validation of Education Study Program lecturers at FMIPA UM and science teachers at SMPN 8 Malang. The readability test was carried out on 31 students of SMPN 8 Malang grades 9E and 9F who had received material on the physics of the human circulatory system. The percentage of UKBM product validity was 85.41% and the readability test percentage was 87.98%. Based on these results, the PBL-based UKBM on the Physics of the Human Circulatory System Oriented Critical Thinking Skills was declared valid and passed the readability test.
