Abstract

Telah dilakukan kegiatan pengabdian kepada masyarakat (PPM) dengan tujuan untuk menerapkan teknologi tepat guna integrating fish and plant culture untuk meningkatkan ketahanan pangan keluarga pada masa pandemic Covid-19. Kegiatan PPM ini dilaksanakan dengan metode pelatihan, demonstrasi, dan pendampingan. Pelaksanaan pelatihan dibagi menjadi 2 sesi yaitu sesi pertama pemaparan materi dengan menggunakan metode ceramah, demonstrasi, dan diskusi. Sesi ke dua pendampingan kepada untuk menerapkan teknologi tersebut. Instrument yang digunakan dalam kegiatan PPM ini adalah angket untuk menjaring data respon peserta terhadap kegiatan pelatihan yang telah dilaksanakan.  Kegiatan pelatihan ini melibatkan 15 orang warga dari desa bukit peninjauan 1 cahaya negeri dengan tetap mematuhi protocol klesehatan. Jumlah peserta dibatasi mengingat kita harus menerapkan social distancing dan menghindari kerumunan. Perkembangan ikan lele dan sayuran diukur melalui observasi langsung. Berdasarkan hasil kegiatan pelatihan diketahui bahwa media untuk menerapkan teknologi integrating fish and plant culture berhasil dibuat. Berdasarkan hasil angket respon diketahu bahwa rata-rata 93% dari total peserta sangat setuju bahwa kegiatan pelatihan yag telah dilakukan memberikan banyak manfaat khusus nya untuk pemenuhan kebutuhan pangan keluarga terutama dimasa pandemic. 87% dari total peserta pelatihan menyatkan bahwa mereka dapat memahami dengan baik materi yang telah disampaikan. Peserta pelatihan menyatakan bahwa teknologi yang diajarkan didalam kegiatan pelatihan mudah untuk diterapkan secara mandiri dengan biaya yang relative rendah dan pemeliharaan yang lebih mudah. Berdasarkan hasil observasi, pertumbuhan ikan lele dalam media ember dan pertumbuhan sayuran dalam media netpot relative sangat baik. Berdasarkan hasil dan pembahsan dapat disimpulkan bahwa teknologi tepat guna berupa integrating fish and plant culture dapat menjadi solusi permasalahan ketahanan pangan keluarga dimasa pandemic covid-19 karena mudah untuk diterapkan, biaya reatif murah, pemeliharaan yang relative mudah.

Abstract

This study aims to establish the feasibility of developing a moment of inertia material teaching aid utilizing the Arduino Nano and the TCRT5000 sensor based on the opinions of media experts and material experts, the precision of the tool, and the responses of students to the created teaching aids. This study employed the ADDIE methodology comprising five stages: analysis, design, development, implementation, and evaluation. The average mistake percentage for acrylic material was 4%, cake mat was 13%, and rice paper was 10%, according to the findings of the accuracy of the teaching aid on the moment of inertia material based on Arduino Nano and the TCRT5000 sensor. Based on the data analysis, it can be concluded that the validation of teaching aids on the moment of inertia material based on the Arduino Nano using the TCRT5000 sensor by three media experts obtained an average score of 95% in the "very feasible" category and by three material expert validators on teaching aids obtained an average percentage of 97.33% in the "very decent" category and the guidebook an average percentage of 99% is in the "very decent" category. Student reactions to teaching aids received an 80 percent score in the "very suitable" area and a 79 percent score in the "good" category for the handbook. Thus, the Arduino Nano-based moment of inertia teaching aid utilizing the TCRT5000 sensor is ideal for school usage as a learning tool and can stimulate a desire to study.

Abstract

Brownian motion is the random motion of nanoparticles in the fluid. The concept of Brownian motion is one of the abstract concepts of physics. Thus, it is difficult to learn. Most schools also don't teach Brownian motion in depth in high school. Including the Senior High School 5 Bengkulu City. In fact, there are a lot of Brown motion applications. For this reason, the introduction of Brownian motion in easy-to-understand language needs to be taught to students. The method used in this research is the method of preparation, implementation, and evaluation. From this research, it can be seen that students are very enthusiastic about listening and answering every question that is asked. There is also a very active participation. The competitive spirit of students is also visible. So, it can be concluded that, no matter how difficult and abstract Brown's motion is, if it is taught in simple language, students are also able to understand it well.
