Abstract

Thin film copper-based RTD still has a low TCR. Hence, plating a Cu-based RTD with nickel will develop a higher TCR. TCR is the sensitivity of RTD’s value in response to temperature change. The experimental design in constructing Cu/Ni thin film by using the electroplating method with a concentration of solution and electrode spacing’s variation has been done. Electroplating is performed with a concentration of solution and electrode spacing’s variations. Electroplating processed by limiting DC voltage to 6 volts. Electrolyte solutions composition were NiSO4, Ni2Cl2, H3BO3 and aquades. Concentrations of solutions can be varied by changing NiSO4 and Ni2Cl2 masses. Based on these concentrations of solutes and electrode’s spacing, this research used 15 samples. Thickness, thin-film resistance, and temperature sensor test are performed to each sample. The purpose of thickness test is to measure nickel plates which were formed from the electroplating process. Thin-film resistance test performed to measure sample resistance changing to the electroplating process, and the temperature sensor test was performed to measures the sample’s sensitivity in responding to temperature changes. This research’s result shows the greater the concentrations of solutes used for copper electroplating, the thicker nickel plates will form. This condition makes its resistance’s value decreasing.Keywords: thin layer resistance, concentration of the solution, electrode distance, electroplating, thin layers of Cu / Ni, RTD, modules

Abstract

The research describes an analysis of regrouping public elementary school implementation plans in Magelang. The research method used is a qualitative method with instruments of open interview sheets and documents. The research results indicate that schools eligible for the regrouping consist of 1) SDN Wates 1 with SDN Wates 5; 2) SDN Rejowinangun Utara 2 with SDN Rejowinangun Utara 3; 3) SDN Kramat 2 with SDN Kramat 3. At the same time, schools that are less eligible for the regrouping include SDN Magersari 1 and SDN Magersari 3 since each school has unique characteristics that require special handling. Recommendations or suggestions that the regional department of education can apply are 1) intensive coordination or communication with all stakeholders; 2) unique approaches to potential resistant parties; 3) the design of the utilization of regrouped school assets; and 4) post-regroup buildings to meet the mandatory affairs of the Regional Government in the Education sector, such as community activity center (SKB) building, the secretariat of school supervisors, education council, and integrated art Council. The research implication becomes a reference in improving education quality in Magelang city through elementary school regrouping.

Abstract

Literasi sains merupakan pemahaman atas sains dan prosesnya serta aplikasinya dalam masyarakat, Literasi sains sangatlah diperlukan dalam dunia pendidikan sebagai upaya dalam meningkatkan sumber daya manusia (SDM) di Indonesia. Salah satu karakteristik dari orang yang memiliki literasi sains yaitu memiliki pemahaman tentang Nature of Science (NOS). Metode penelitian yang digunakan dalam penulisan artikel ini adalah metode studi literatur, metode penelitian yang dilakukan tanpa turun ke lapangan dan bertemu responden secara langsung. Berdasarkan hasil penelitian yang dikaji menyebutkan bahwa pembelajaran yang berorientasi pada peserta didik mampu mengembangkan dan meningkatkan literasi sains peserta didik. Karena pada pembelajaran tersebut mampu memberikan pengalaman secara langsung, sehingga dapat diaplikasikan dalam kehidupan sehari-hari dalam menyelesaikan suatu permasalahan. Salah satu model pembelajaran IPA yang dapat digunakan untuk mengembangkan literasi sains peserta didik yaitu pembelajaran berbasis inkuiri “inquiry-based life-cycle thinking project”. Integrasi secara eksplisit antara NOS dan inkuiri ilmiah mampu mengembangkan literasi sains, sehingga dalam proses pembelajaran dilakukan secara eksplisit.

Abstract

The environmental education course currently does not integrate problem-solving problem skills. The purpose of this study was analyzing the results of applying integration on problem-based learning with the RMS (reading, mind mapping, and sharing) learning model. The research method was a quasi-experimental with pre-test-post-test control group design. The study was conducted on 56 students who took an environmental education course in Natural Science Education Universitas Tidar. Data analysis used an Anacova test with a pretest as its covariate. The study results stated that 1) developed learning model integrates PBL with RMS learning model consisting of identifying problems, finding relevant information about problems through reading activities, analyzing problem: group discussion through mind mapping, providing solutions, and sharing results of mind mapping. 2) The integration of PBL with the RMS learning model indicated by an average score of post-test in the integration of PBL with the RMS learning model class of 68.46, and the traditional class of 48.92. 3) the learning process that occurs in the integration of PBL with the RMS learning model class shows that learning is run well, which is indicated by students' average evaluation score of the lecturer learning process. The integration of PBL and RMS model can be utilized by teachers and lecturers in Biology learning to have thinking skills and solve daily problems.

Abstract

Scientific literacy can prepare quality human resources who can develop the ability to think logically and creatively, solve problems, be critical, master technology and be adaptive in the face of change and face the times. A vital component to improving students' scientific literacy is understanding the Nature of Science (NoS), which must be emphasized in science learning. The purpose of this study is to obtain a comparison of content and explain aspects of NoS in science textbooks in Indonesia and Singapore. The research approach used is descriptive qualitative with content analysis design. This research focuses on science books for Junior High School Class IX Semester 1 Curriculum 2013 Revised Edition 2018, Integrated Science Books for Junior High School Class IX Curriculum 2013 Revised Edition 2018, and Lower Secondary Science Matters Textbook Volume B 2nd Edition 2013. The data collection techniques are by reviewing documents with non-test instruments in the form of observation guidelines for assessing textbooks based on the NoS aspect developed by Abd-El-Khalick et al., (2008). The data analysis technique uses the fixed comparison method by Moleong (2014). The results obtained are that the textbooks from the two countries have represented several relevant aspects of NoS. Still, the theoretically-driven elements have not been found in the three books, and the existing components have not been well described. Science textbooks in Singapore get a higher score than science textbooks in Indonesia. Still, the availability of the NoS aspect of science textbooks in Indonesia is more than that of science textbooks in Singapore.

Abstract

There have been several cases that reflect the moral and character decline of Indonesian students. Based on some previous studies that have been carried out, ethnoscience and STEM-based worksheet can improve scientific literacy skills and grow students’ character. The aims of this research are to test the feasibility of RE-STEM-based (Religious, Ethnosains-Science, Technology, Engineering, and Mathematics) science worksheet to improve students' scientific literacy and character, and to find out the students' responses to science worksheet based on RE-STEM as an effort to improve students’ scientific literacy and character. This research applies the development research method with the ADDIE model. The sources of data in this study are the results of expert validations and student response questionnaires, while the research subjects are the experts and students. Data collection techniques and instruments in this study used the expert validation sheets and student response questionnaire sheets. The data analysis technique consists of two things namely the worksheet feasibility test using the V'Aikens value, and the student response test using the Likert scale of student responses which is then converted to a score interpretation table of five criteria. The results showed that the validity of the developed worksheet was categorized as valid with an average V'Aikens value of 0.86, so that the product developed was feasible to use, while the students’ response after using such the developed worksheet is very good with a percentage of 86.17 percent. Thus, the developed RE-STEM worksheet has accomplished the validity requirements and received a good response from students, so that it can be implemented in the learning process.
