Abstract

Research on absorbent core and elastic-modified coconut fibre is motivated by the use of coconut fibre in terms of water absorption and elasticity. This study aims to: (1) determine the percentage of the absorbent core and elastic-modified coconut coir; (2) compare the percentage of the absorbent core and elastic-modified coconut fibre to the diapers X. The design used was experimental. The tools and materials consisted of modified coconut fibre, a Pasteur pipette, a specimen clamp, and a software system. Modified coconut coir was made from a mixture of Cinnamomum verum and Mutingia calabura L., with a sample mass ratio to diapers X, which was 1:40, circular shape with a diameter of 3 cm. The treatments for modified coconut coir were sun drying (Sample A) and a hair dryer (Sample B), which resulted in differences in the Absorbent core (Ab) and Elastic (E). The sample was forwarded for the E-test through the Tracker software system, which can detect the centre of mass of the object through the experimental video recording, and the other sample was measured Ab through the difference in the volume of water absorption. The results showed that Sample B could be used as an engineering material for Ab and E diapers X. It was concluded that: (1) %Ab-Sample B = 38.36%, %Ab-Sample A = 25.57%, %E-Sample B = 1.2%, %E-Sample A = 0.5%; (2) comparison of %E-Sample B to %E-Diapers X was 67%, and %E-Sample A to %E-Diapers X was 27%.

Abstract

The era of educational revolution 4.0 and society 5.0 requires students to have research skills. An independent curriculum with a new learning paradigm enables the realization of student research skills and a research culture in schools. The current condition of students' research skills in Rembang is still low. Meanwhile, in Rembang there is the Indonesian Teachers Association (IGI) community which can be empowered to become partners in realizing a research culture in schools. It is necessary to provide teachers with learning models that can facilitate students doing research. through the application of the Differentiate Indirect Learning (DIF-IN-LE) learning model with a Science, Technology, Engineering and Mathematics (STEM) approach. The objectives of this service activity are (1) to equip IGI Rembang administrators in holding fun and meaningful training for teachers, (2) to equip teachers with the knowledge and skills to innovate in implementing the DIF-IN-LE learning model with a STEM approach, in fostering a research culture in students and school. The solution to the problems in this service is by applying training and facilitation methods to partner groups, so that they are skilled at designing and implementing the DIF-IN-LE learning model with a STEM approach for teachers in Rembang. Activity design uses the facilitation-based 4M Genre model (Genre 4M-F). The service activity plan consists of preparation, implementation and evaluation stages. The results of the activity show an increase in teachers' abilities in designing learning that can foster research skills for students

Abstract

Fabrikasi film tipis di atas substrat kaca yang homogen dengan sifat optik dan listrik yang unggul masih menjadi tantangan. Oleh sebab itu, pemilihan metode serta parameter fabrikasi menjadi hal yang penting untuk diteliti. Pada penelitian ini, film tipis ZnO doping Mg (ZnO:Mg) difabrikasi pada substrat kaca menggunakan metode Microwave Assisted Spray Pyrolysis dengan memvariasikan tekanan spray nitrogen, yaitu sebesar 1,4; 2,1; 2,8; 3,5; dan 4,2 kg/cm2. Film tipis yang telah difabrikasi kemudian diuji dengan UV-Vis dan IV-meter untuk menganalisis sifat optik dan listriknya. Hasil penelitian menunjukkan bahwa tekanan spray memiliki pengaruh signifikan terhadap karakteristik optik dan listrik dari film tipis ZnO, Dengan peningkatan tekanan spray, film tipis yang dihasilkan cenderung memiliki ketebalan yang lebih seragam, yang berkontribusi pada peningkatan transparansi optik dan penurunan nilai resistivitas listrik. Metode penelitian yang digunakan adalah deskriptif kuantitatif. Penelitian ini bertujuan. Dalam penelitian ini, sampel yang digunakan adalah film tipis ZnO (seng oksida yang didoping dengan magnesium). Tujuan dari penelitian ini adalah untuk mengeksplorasi dan memahami pengaruh variasi tekanan spray pada proses sintesis terhadap sifat optik dan listrik dari film tipis ZnO yang dihasilkan menggunakan metode Microwave Assisted Spray Pyrolysis (MASP). Implikasi penelitian ini adalah penelitian ini memberikan wawasan baru tentang bagaimana parameter proses sintesis dapat diatur untuk mengoptimalkan kinerja material. Temuan ini mengindikasikan bahwa dengan pengaturan tekanan spray yang tepat, film tipis ZnO.
