Abstract

Some previous studies have shown that electricity and magnetism is one of the concepts of abstract, difficult, and complex. The purpose of the research illustrates the difficulties of academic cross-level physics education students on magnetic electrical concepts. Research used qualitative descriptive methods. The number of research samples is 103 students consisting of 73 the third year Bachelor?s Students of Physics Education and 30 Master?s Students of Physics Education in one of State University in Bandung City. Research instruments used essay-shaped tests and interview guides. Data collection was conducted by giving essay test adapted from Electromagnetic Concept Inventory test consisting of four major subconcepts namely: electrostatic, magnetics, electromagnetic induction and electromagnetic waves.  Data analysis was conducted by analyzing the test result data via the answer scale section and analysis of the interview results. The results of the study show interesting thing that the electrostatic subconcept is 3% for Bachelor?s Students of Physics Education and 6% for Master?s Students of Physics Education that answered questions correctly on the concept. In the sub-concept of electromagnetic waves, 7% of Bachelor?s Students of Physics Education and 6% for Master?s Students of Physics Education that answered correctly questions on the concept. The results indicate that most students ' cross-academic level difficulties were on electrostatic sub-concepts and electromagnetic waves that categorized the basic and upper concepts in magnetic electrical concepts. The results of the study give implications that the need to strengthen basic concepts and appropriate learning strategy in teaching the concept of magnetic electricity.

Abstract

The utilization of aquaculture, especially in freshwater fish farming potential, is still not optimal. In general, fish feeding is still done manually and depends on human resources which is done simply. So an automatic fish feed thrower based on solar cells was designed to minimize the risk of delays in feeding fish. This innovation can be integrated in learning where it is adapted to physics content. This research uses a mix of methods with data collection techniques in the form of observations related to the surrounding environment and the learning process, documentation in the form of learning tools such as syllabus, lesson plans, curriculum, documentation, questionnaires, testing feed machine tools and literature studies. This research instrument is in the form of descriptive observation sheets, observation analysis sheets testing feed machine tools. Analytical techniques in this study use descriptive, qualitative and quantitative analysis techniques. The results of this research are in the form of content integration in physics learning in the context of designing a solar cell-based automatic fish feed throwing machine consisting of 6 physics contents that are adapted to the context of solar cell-based automatic fish feed throwing machines. The results of this study show that the application of the use of an automatic machine for throwing fish feed based on solar cells can be used as a source of learning, especially in physics subjects.

Abstract

Briquettes represent environmentally sustainable solid fuels that utilize renewable resources. This study aimed to assess the quality of bagasse waste briquettes as an alternative in eco-friendly technology. The experimental method was conducted internally at the PT SUCOFINDO Bengkulu laboratory. Briquettes were produced using varying compositions of bagasse waste: A1 (80 grams charcoal flour and 12 grams tapioca flour), A2 (30 grams charcoal flour and 6 grams tapioca flour), and A3 (20 grams charcoal flour and 5 grams tapioca flour). The production process involved preparation, drying, monitoring, grinding, adhesive mixing, molding, and final drying. Quantitative data analysis focused on key parameters including water content, ash content, and calorific value. Results indicated that the briquettes with 80% charcoal flour and 20% tapioca flour exhibited the highest calorific value at 6155 kcal/kg. It was concluded that all types of bagasse waste briquettes met Indonesian National Standards, demonstrating their potential as an alternative energy source through environmentally friendly briquette technology.
