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

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

The position of the leaves on each plant can affect the thickness of the leaf tissue. This study aims to determine the thickness of the leaf tissue at the base and shoot positions. The study used a nested design model (random nesting pattern design). This design uses two factors, the first factor is the leaves of six types of monocot ornamental plants, namely adam hawa (Rhoeo discolor), daffodils (Hymenocallis littoralis), hanjuang (Cordyline fructicosa), lilies of paris (Chlorophytum laxum), song india (Dracaena reflexa) and sri fortune (Aglaonema commutatum), while the second factor was leaf position (base and shoot) with three replications. The method of making leaf preserved preparations is paraffin which refers to Johansen. Parameters measured were total leaf thickness, upper epidermis, lower epidermis, mesophyll (palisade and sponge). Data were analyzed with ANOVA followed by LSD if the factor results were significant. The correlation was made between the total leaf thickness and the tissue which was significant on the leaf position factor. The results showed that the type of plant affected the total leaf thickness, upper and lower epidermis, mesophyll (palisade and sponge). However, leaf position has no effect on the thickness of the upper epidermis and sponge for differentiated mesophyll. The thickness of the leaf depends on the thickness of the lower epidermis, followed by the thickness of the mesophyll or palisade for differentiated mesophyll.
