Pengembangan energi substitusi terbarukan dan ramah lingkungan harus dilakukan untuk menggantikan peran energi fosil. Salah satu teknologi untuk menghasilkan energi ini adalah microbial fuel cells (MFCs). Teknologi ini memanfaatkan mikroorganisme untuk menghasilkan listrik secara langsung melalui perombakan molekul organik dalam proses respirasi seluler. Penelitian ini merupakan penelitian awal yang bertujuan untuk mengeksplorasi substrat dan mikroorganisme yang berpotensi untuk digunakan dalam teknologi MFCs. Tipe reaktor MFCs yang digunakan adalah membraneless, single chamber air-cathode. Substrat yang diinokulasi ke dalam reaktor diambil dari tiga sumber yang berbeda, yaitu endapan lumpur bakau, tanah berlumpur dari kebun dan endapan saluran pembuangan rumah tangga. Material elektroda yang digunakan adalah kombinasi stainless steel mesh dan karbon aktif. MFCs dioperasikan selama 3 siklus (1 siklus = 7 hari), dan di akhir siklus, reaktor MFCs dibersihkan dan diganti dengan substrat yang baru. Hasil pengoperasian MFCs selama 3 siklus menunjukkan bahwa substrat dari endapan lumpur bakau menghasilkan tegangan listrik sebesar 101,54 mV. Sedangkan, substrat tanah berlumpur dan endapan saluran pembuangan rumah tangga menghasikan tegangan sebesar 15,8 mV dan 13,06 mV. Dengan penelitian yang lebih mendalam, substrat endapan lumpur bakau berpotensi untuk digunakan dalam teknologi MFCs. Penelitian ini diharapkan dapat memperkenalkan teknologi MFCs kepada masyarakat, agar dapat dikembangkan untuk mengelola limbah dan menghasilkan energi terbarukan.

This research is a descriptive study which aimed to describe the comfort level of respondents in applying each type of right-hand rule (RHR) to determine the direction of the Lorentz force (forward reasoning) and the direction of the velocity of a charged particle (backward reasoning) moving in a homogeneous magnetic field. The respondents of this study were 10 Pre-Service Physics teachers who were at 2nd, 4th and 6th semesters. The results showed that although each type of right-hand rule, when applied accurately, would show the same result, the comfort level of the respondents in applying each type the right hand rule (RHR) is different. This difference is influenced by the clarity and simplicity of the instructional description of each type of the RHR and the ease of matching or pairing the position of fingers (and also the palm) on each type of RHR with vectors positions. The study revealed that the right hand rule type III is the most preferable RHR for the majority of respondents (80%).

An ability that plays an important role in learning mathematics and physics in the 21st century is mathematical literacy skills. This study aims to analyze the mathematical literacy ability of students using the PhET Simulation-assisted Discovery Learning learning model in Spring Potential Energy material. This type of research is pre-experimental using a one-group pretest-posttest design. The subjects of this study were 13 students of class XI MIA SMAK Santa Maria Monte Carmelo Maumere. Students before learning are given an initial test and at the end of learning are given a final test with the same material and form of questions. The pretest and posttest result data were then analyzed using validity tests, reliability tests, normality tests, homogeneity tests, paired t-tests, and n-gain calculations with IBM SPSS Statistics 26. This study showed a significant increase in scores after being given physics learning using the Discovery Learning learning model. The Discovery Learning learning model assisted by PhET Simulation is effective in improving students' mathematical literacy skills. This is evidenced by the significant value gains on paired t-tests and n-gain tests are 0.023 and 0.8531 respectively. With this, the Discovery Learning learning model assisted by PhET Simulation can be used as a reference or consideration for teachers to improve students' mathematical literacy skills.

In order to explore alternative methods to learn physics effectively, this research was inspired by a fundamental question: how did famous physicists use to learn and/or teach physics? Are there any recipies suggested by these physicists which are still relevant and can be imitated and applied to physics learning in a today classroom? This research aims at exploring the impact of the implementation of Feynman learning method on students’ physics concepts understanding and describing their spontaneous responses about the implementation of this learning method afterwards. This research was an exploratory research conducted at one grade X science class of St. Gabriel Catholic Senior High School in Maumere city, Flores. Data regarding students’ understanding were collected through pre and post test questionnairres and their spontaneous responses were obtained through unstructured interview. The results of N-gain pretest and post test score was 0.49. Apart from few non-positive responses, students’ responses indicated that the method can encourage them to actively participate in the learning process, improve their communication skill, and train their abilities to explain things in simple ways. The results suggest that there was an improvement in students’ physics concepts understanding with a medium N-gain score and that this learning method is positively appreciated by the participants.
