Abstract

Kajian kegempaan suatu wilayah terutama di daerah rawan gempa bumi seperti Jawa Timur sangat diperlukan dalam rangka mengurangi dampak yang ditimbulkan akibat bencana gempa bumi. Dalam konteks ini, dilakukan penelitian yang bertujuan untuk menganalisis tingkat seismisitas di wilayah Jawa Timur antara tahun 1999-2013 yaitu dengan menganalisis hubungan antara frekuensi kejadian gempa bumi (N) dan magnitudo gempa bumi (M). Rumus umum yang digunakan, yaitu log N = a ? bM. Gradien persamaan ini atau nilai b merupakan parameter tektonik yang menggambarkan sifat batuan pada daerah yang diteliti sedangkan nilai a menggambarkan aktivitas tektonik wilayah yang diamati. Data yang digunakan dalam penelitian ini merupakan data sekunder parameter gempa bumi dari bank data seismologi IRIS dengan magnitudo 4,0-10,0 SR pada kedalaman 0-200 km yang berlokasi antara 110o-115o BT dan 5o-10o LS. Berdasarkan hasil analisis dengan metode maximum likelihood, didapatkan besarnya parameter seismisitas untuk wilayah 1 diperoleh nilai a sebesar 11,7 dan nilai b sebesar 1,86. Sementara untuk wilayah 2 diperoleh nilai a sebesar 9,69 dan nilai b sebesar 1,49. Hasil analisis menunjukkan bahwa wilayah 1 memiliki tingkat seismitas yang lebih besar dibandingkan wilayah 2. Sedangkan nilai b pada kedua wilayah relatif sama. Hal tersebut menunjukkan bahwa batuan pada wilayah Jawa Timur memiliki heterogenitas yang rendah.

Abstract

The Korean-themed content produced by the YukNgaji community represents an innovative approach to da'wah in response to global trends. This study aims to analyze YukNgaji community's da'wah strategies targeting "Hallyu" fans through Korean-themed content. The research employed a literature study approach, gathering qualitative data primarily from YukNgaji's social media and using related articles and websites as secondary sources. YukNgaji's da'wah strategies include using popular Korean terms, Korean-themed da'wah media, Korean language classes, and X-School classes. The strategy applied without any element of coercion and does not judge Korean culture fans, but rather uses Korean culture as an approach to make it easier to understand and attractive to Korean culture fans. This research serves as an initial proposes innovations in spreading da'wah to specific participant segments, including Korean culture fans.

Abstract

Obesity is a global health problem that requires education-based solutions. This study aims to provide students with critical habits in choosing food through biology learning based on the FatSecret application on digestive system material. The research method used a pre-experimental approach with a one-group pretest-posttest design, involving 29 grade XI students. The learning design was developed based on the ADDIE instructional design model. The research instrument was a questionnaire of students' awareness of healthy eating patterns, which is based on eight points of recommendations from the Ministry of Health, as well as a questionnaire of students' responses to learning. The results showed that the majority of students experienced positive changes in healthy eating habits after learning, with 50.6% of students showing an increase in critical awareness. The FatSecret app proved effective in helping students record and analyze daily food consumption data. A total of 62% of students stated that the learning helped them plan a healthy diet, while 75.9% felt more aware of their food consumption. However, there were challenges such as students' difficulty in developing realistic action steps and limited understanding of nutrition. This activity confirms that technology integration in biology learning can foster students' critical habits in choosing food, with recommendations for improvement in action planning assistance and strengthening understanding of nutrition concepts.

Abstract

This study aims to evaluate and test the feasibility of a student worksheet (LKPD) on bacterial cultivation and observation from a Natural Science textbook for grade X senior high school as a means to foster deep learning in the context of the deep learning. Using the Vee Diagram approach, the analysis shows that the LKPD contains several fundamental shortcomings—particularly in its unclear learning objectives, unsystematic procedures, and minimal space for reflection and data transformation. Through a self-conducted practicum trial, these identified weaknesses were indeed reflected in field implementation. Although the practicum was conducted, it faced issues such as overly dense colony growth, contamination, and inappropriate inoculation techniques, which led to suboptimal observations. This confirms that the structure and instructions in an LKPD significantly influence the success of experimental learning. Nonetheless, the activity revealed potential for further development. The practicum offers students the opportunity to experience scientific processes firsthand and understand the connection between biological concepts and real-life phenomena. With improved structure and approach, the LKPD can serve as an effective tool to support deep learning.
