    Kurzfassung: Activated carbon or activated charcoal is one of the best materials that can be used as a constituent of CDI electrodes, not only because of its various advantageous properties but also because it can be sourced abundantly from plant waste. This research aims to determine the effect of the thickness of the candlenut shell activated charcoal electrode and the particle size of the activated carbon used on the capacitive deionization (CDI) performance in seawater desalination. Candlenut shell-based activated charcoal is obtained in three stages, namely preparation, carbonization, and activation. The carbonization stage was done by using a pyrolysis reactor at a temperature of 400°C for 8 hours. The activation was done with the activator of H3PO4 67%. The variation of thickness was 6 mm, 8 mm, 10 mm, and 15 mm while the variation of particle size was 60 mesh, 80 mesh, 100 mesh, and 200 mesh. The results showed that the higher capacitance was obtained with the thinner electrodes, where the best value was the thinnest electrode, 6 mm, which produced the highest capacitance, 122.96 nF. For the desalination of seawater, it is shown that the finest particle/smallest particle size will result in the best desalination performance, where 200 mesh particle size will result in the decrease of salinity from 34% to 4%. That is 88.23% decrease in salinity. Therefore, the using of candlenut shell-based activated carbon as the electrode in CDI is proven to be able to obtain good performance in seawater desalination.

    Kurzfassung: Activities seek to improve the awareness and information of teachers about the role of educational media in Junior High School learning activities. Furthermore, this curriculum also teaches SMP TQ-Mu'adz Bin Jabal teachers to use the Powtoon technology to design and render instructional videos. Increasing teacher imagination in the creation and use of video learning media is the specific goal to be accomplished, so that science learning in schools can be more contextual. The method used in implementing this Community Service is counselling, training, and question and answer methods. This activity begins with observations in schools and related institutions/agencies in the first week, followed by core activities at SMP TQ-Mu'adz Bin Jabal Kendari. From the results of the dedication, it was found that: (1). This activity has been able to increase teacher knowledge about the urgency of instructional media and the development of forms of instructional media, especially those related to technological developments; (2) This activity has been able to improve the ability of teachers to operate computers or laptops, including in making online-based learning videos that are integrated into Powtoon.

    Kurzfassung: The purpose of this research is to provide innovations to physics education lecturers in using physics learning media based on Macromedia Flash applications in lectures as a learning medium and students can improve their problem-solving abilities in solving problems in other fields.. Also, motivating physics education lecturers to use technology in conducting lectures in the room. The target of this research is in the form of products resulting from the development of learning media based on Macromedia Flash applications. The resulting product is expected to: (a) improve the ability of problem-solving in students, (b) motivate physics education lecturers to use technology in conducting lectures in the room. This research method is Reseach and Development by using a development model that consists of five stages : (1) preliminary investigation, (2) design, (3) realization/construction, (4) test, evaluation, and revision. Preliminary results of this study are the feasibility of developing learning media based on Macromedia Flash applications to improve students' problem-solving abilities on the subject matter of passive electronics can be seen based on the assessment or validity of the material experts obtained a mean score of 3.55 with a valid category. For the assessment or validity of the media, experts obtained an average of 3.63 with a valid category. The effectiveness of the results of the development of learning media based on Macromedia flash applications to improve students' problem-solving abilities on the subject matter of passive electronics can be seen based on inferential analysis using the test paired t–test was obtained tcount = 10.60 dan ttable = 2.05 with a significant level of 5%, df = 29. The results of these calculations show that tcount 〉 ttable which means that the difference is due to the provision of different behaviours every time they conduct a pre-test evaluation before there is treatment and post-test after there is a treatment.

    Kurzfassung: Has successfully created the INoSIT learning paradigm to increase students' science literacy competency. This design aims to integrate information and communication technology (ICT) with inquiry and nature of science (NoS) models to teach scientific literacy to junior high school students using a multi-representation method. The BSCS 5E model (Involvement of Biological Science Curriculum Study, Exploration, Explanation, Elaboration, and Evaluation) and the IBL model (Investigation-based learning) have many phases whose implementation requires many processes. So, the INoSIT model is designed to simplify multiple phases or sub-phases. As a result, IBL (inquiry-based learning) is ineffective and inefficient in terms of learning time. It is also challenging to teach scientific literacy of abstract concepts using this method. The study employs a descriptive analysis method in conjunction with a literature review pattern.  The INoSIT model with the syntax Eliciting, Hypothesis, Testing Hypothesis, Elucidation, and Reflection was created from the results of the investigation of the weaknesses of the BSCS 5E (Biological Science Curriculum Study Engagement, Exploration, Explanation, Elaboration, and Evaluation) and the IBL (Inquiry-based learning) models. To construct students' knowledge of literacy and the study is anticipated to contribute to creativity, originality, and the development of a proclivity for inquiry and research
