Abstract

This research is a qualitative research whose background is that there are still some students who still do not reflect Pancasila behavior both during learning and outside of learning. This study aims to analyze character strengthening through the application of Pancasila values ​​in thematic learning of science content at SDN 008 Samarinda Ulu. The technique used in this triangulation is triangulation of data sources to test the validity of the data. The results of research that has been carried out by researchers in class IVB SDN 008 Samarinda Ulu is that the teacher has applied Pancasila values ​​in the thematic learning of science content so that it influences student character. Its application is by getting students to pray, say hello, greet. The teacher gives freedom to students to express opinions, respect differences, help others, consult, and be fair when learning takes place which is integrated with strengthening religious, national, independent and mutual cooperation characters. There are no difficulties in strengthening character through the application of Pancasila values ​​in thematic learning

Abstract

The golden snail is a pest that causes crop failure in rice plants. Farmers control the golden snail by using pesticides, which can have a negative impact on the environment, so another alternative is needed that can control the golden snail, namely vegetable pesticides. This study aims to determine the effect of a combination of oleander leaf extract and neem leaves on the mortality of Keong Mas. The method used in this research is the experimental method with a factorial completely randomised design (CRD). The study consisted of 2 factors, namely factor N (Oleander leaf) and factor A (Azadiracta indica leaf), each of which had 4 levels, so there were 16 treatment combinations and 3 replications. There were 480 golden snails in the study. After 12 hours of observation, the N3A3 treatment tested by ANOVA showed significantly different results (fcount > ftable = 66.00 > 2.01) and caused 30 test animals to die with a mortality rate of 77%.  The conclusion from this study is that the combination of oleander leaf extract with neem leaves greatly influences the mortality of the golden snail

Abstract

Experiments have been successfully carried out to react with lactic acid and 1,4-butanediol, tin (II) chloride dihydrate (SnCl2.2H2O), chloroform, methanol, liquid nitrogen, nitrogen gas, and silicone oil at various concentrations. The objective exists to synthesize polylactic acid by forming polylactic acid diol (PLA-OH) via a direct polycondensation reaction of lactic acid and 1,4-butanediol in a glass reactor following a specific reaction scheme. Synthesis was carried out using different amounts of reagents according to the predetermined mole ratio of lactic acid (AL) and 1,4-butanediol (BD). The FTIR, 1H NMR, and GPC analyses that characterized the PLA-OH revealed its physicochemical characteristics. The FTIR and 1H NMR characterization results show new absorption peaks and a shift in PLA-OH absorption peaks. It indicates that a bond has been formed from the reaction between lactic acid molecules and 1,4-butanediol to produce PLA-OH. From the spectrum analysis, it can be concluded that the structure of the synthesized PLA-OH has four different proton environments (there are four different peaks in the spectrum). The peaks originate from the protons in methylene (-OCH2CH2CH2CH2O), internal methine (-O-CH-), and methine at the end of the PLA-OH chain, as well as proton peaks in methyl (H3C-). The characterization results with GPC showed that the tendency to increase Mn PLA was directly proportional to the increasing amount of lactic acid in the PLA chain

Abstract

Conceptual understanding is the capacity to grasp a variety of learning resources in which pupils are able to not only recognize and know the concepts, but also re-express them in a way that is easier to understand and apply. Students' conceptual comprehension skills in STEAM-integrated Project Based Learning on static fluid materials are the focus of this study. This study was carried out with the use of an embedded experimental model of mix methods. The participants in this study are 36 senior high school students of grade XI in Salatiga. Students' concept understanding exam scores at the pre-test and post-test were used to generate quantitative data. The test scores were examined using the statistical description test, normality test, t-test, N-Gain score, and Effect size. Qualitative data was gathered through students’ interviews following the completion of the pre- and post-tests, it was analyzed using Abraham's concept understanding level category (1992). There is improvement of students’ conceptual understanding, i.e. 16,66% students improved from partially understand to understand; 66,66% students improved from partially misconception to partially understand; and 16,66% students improved from misconception to partially misconception. Thus, the conceptual understanding of most of the students improved after they experience STEAM-based Project Based Learning

Abstract

Science process skills need to be owned by students in learning science. With science process skills, it is easier for students to conduct research and solve life problems by implementing science learning outcomes. Nevertheless, science learning involving science process skills is still challenging for teachers. This study aims to produce collaborative-based worksheets on natural science learning materials in junior high schools. The type of research used is Research and Development with the Plomp development model, which consists of 3 stages: a preliminary study, a prototyping stage, and an assessment phase. The subjects used for product trials were class VIII students of SMP Negeri 2 Ajung Jember. The results showed that the validity of the collaborative-based worksheet obtained very valid criteria with a percentage value of 93.25%. Based on the practicality test, collaborative-based worksheets are included in the convenient category and are suitable for learning with a percentage of 96.45%. In the effectiveness test, a practical collaborative-based worksheet is proven to improve students' science process skills by acquiring the N-Gain of 0.6, which is included in the moderate criteria. Based on this study's results, we can state that the science process skills can be developed in students by conditioning science learning that optimizes collaborative activities.

Abstract

The development of technological rapidly changes the learning process more broadly. Demands for students or prospective science teachers to improve their digital literacy skills with the help of website-based media are needed in the learning process so that it can take place optimally. The development of biotechnology has also developed rapidly in the last few years, thus demanding that students or prospective science teachers be more responsive to information and be able to present this information interactively. Unfortunately, many students or prospective science teachers are not able to understand biotechnology because it is considered that the concept of biotechnology is difficult to understand. For this reason, it is necessary to have a needs analysis to find out the aspects needed and develop the learning and learning resources needed to improve digital literacy skills and understand the concept of biotechnology. The aim of this study is to analyze the needs of learning media based on a biotechnology theme website that would be developed, so that it can improve the digital literacy skills of students or prospective science teachers. The needs analysis was carried out as a preliminary study on Borg & Gall's research and development methods, which are included in the research and information collecting stage. The analysis of the needs for developing learning tools includes student analysis, concept analysis, task analysis, and learning objectives analysis. This needs analysis is accompanied by a literature review and observation results. The results obtained are a thorough and real needs analysis on the development of a biotechnology theme website to improve the digital literacy abilities of science teacher candidates, which can be applied at the next research and development stage

Abstract

The Laplace transform is a technique used to convert differential equations into algebra, it is often used for the analysis of dynamic systems and inverted pendulum systems. An inverted pendulum is a mechanism that moves objects from one place to another and shows the function of its activity while walking. This system is widely used in various fields, for example in the fields of robotics, industry, technology and organics. In an inverted pendulum there is an inverted pendulum dynamic system with a reading and driving force. The type of research used is pure research with quantitative methods, the aim is to develop science that aims to find new theories and develop existing theories in natural science. The results of the study show that using the Laplace transform can make it easier to find solutions regarding the inverted pendulum system for a variety of conditions, both in the initial conditions and when given an additional force or load, so it is concluded the application of the Laplace transform is useful for understanding how an inverted pendulum system will react to various forces, loads and initial conditions, which can be used to predict how the system will operate in the real world.

Abstract

Critical thinking skills are still infrequently tested in science classes. This study aims to identify students' thinking skills in integrated science learning with subject temperature and conversion. This type of research uses descriptive quantitative—data sampling using a purposive sampling technique. The subjects of this study were 30 students of class VII SMP Negeri 2 Mlati, Sleman, DIY. The instrument used to identify students' critical thinking skills is within the form of 10 multiple choice tests, with indicators of critical thinking skills consisting of (1) categorizing, (2) concluding deductively and inductively, (3) stating the results, (4) providing solutions and (5) explaining reasons. Data analysis techniques were processed with descriptive statistical data and analysis of each item in critical thinking indicators based on the multiple-choice test results. The results showed that the overall critical thinking skill was 79,33% in the high category. Among the indicators measured, the "categorizing" indicator has the highest percentage, while the “providing solutions” indicator has the lowest percentage. Integrating designs and strategies in further learning media needs to increase student learning activities.
