Demonstrating the Biobriquettes Production using Variations in Particle Size and Binder Concentration using Audio-Visual to Vocational Students

Abstract

The purpose of this study is to improve students' understanding of vegetable waste management through the production of biobriquette using audiovisual experimental demonstration. The study is conducted by conducting a pretest to assess student knowledge; teaching biobriquette using instructional video recordings and content explanations and finalizing video recordings based on the results of the first test analysis. Each step is thoroughly scrutinized with an assessment test. The experimental demonstration conducted by observing the biobriquettes production using peanut shells using variation in tapioca binder concentration (10, 20, 30 40, and 50%) and the peanut shell particle sizes (1184, 582, and 310 micrometers). The teaching analysis shows that students understanding has improved significantly after giving treatment using the audio-visual experimental demonstration as the media improves students' comprehension, gives more information, and stimulates students' curiosity and interest in the subject matter. This research provides new knowledge on the need for educational media to illustrate audio-visual experiments to increase student comprehension.

“ANKER” Video Prosedur K3 untuk Meningkatkan Kesadaran Kerja di Laboratorium Mikrobiologi

“…Video dinilai efektif digunakan karena dapat memenuhi kebutuhan belajar pada fase operasional konkret (Hadi, 2017). Video memadukan audio-visual sebagai media belajar sehingga dapat meningkatkan daya tarik, perhatian, dan motivasi belajar (Nandiyanto et al, 2020;Hernawati et al, 2021) Penelitian yang dilakukan oleh Riyanto & Yunani (2020) memberi gambaran efektifitas video tutorial pada kategori baik sehingga dapat digunakan untuk mengilustrasikan gambaran peristiwa, prosedur atau konsep yang abstrak.Pemanfaatan video sebagai media tutorial dalam pembelajaran bukan hanya memudahkan dalam memahami materi, namun juga memudahkan instruktur membimbing dan mengamati secara langsung (Pritandhari & Ratnawuri, 2015). Melalui penggunaan video tentang K3 dapat mengoptimalkan waktu dan meminimalisir media dalam kegiatan pembelajaran terutama tentang kesehatan dan keselamatan kerja (Wahrini & Hasbi, 2021).…”

How to Calculate Statistics for Significant Difference Test Using SPSS: Understanding Students Comprehension on the Concept of Steam Engines as Power Plant

“…Several previous studies have illustrated the statistical effectiveness of difference tests in revealing significant differences in various contexts. For example, in the field of education, research conducted by Nandiyanto et al (2022); Nandiyanto et al (2020); Ragadhita et al (2023); Afifah et al (2022) used different test statistics to compare student learning achievements between two different learning methods. In the health sector, research conducted by Sun et al (2021) used different test statistics to evaluate the effects of various treatments on patients with certain medical conditions.…”

The Effectiveness of the Practicum Video Guide on Distance Learning in Improving Biology Learning Outcomes in Enzyme Content

“…Several studies on the use of practicum videos in learning have been carried out, including research by Anggraeni et al (2020) regarding the use of experimental videos to demonstrate making sago crackers to students. Nandiyanto et al (2020) also used a practicum video to demonstrate the process of making biobriquettes from biomass to vocational high school students. Research Putri et al (2021) misconceptions that occurred in students regarding their understanding of the abstract concept of adsorption after learning using a video practicum.…”
