Abstract

The purpose of this study was to determine the analysis of teacher and student needs for teaching modules based on regional potential, module validity, level of practicality, and effectiveness of the module in improving students' literacy skills. This study is a development research. Data were analyzed using qualitative and quantitative methods. Qualitative descriptive analysis was used to analyze data on needs, validity, and practicality of the module, while quantitative analysis was used to test the effectiveness of the module. The results of the needs analysis showed that teachers needed modules that were relevant to the local context, and students needed interesting and easy-to-understand learning media. Expert validation showed that the module had a validity index of 97.73% with a very valid category. The practicality level of the module reached 78% with a practical category. Effectiveness testing using the independent sample t-test produced a sig value. (2-tailed) of 0.000 (<0.05), which shows that the module is effective in improving students' literacy skills. The conclusion of this study is that the regional potential-based teaching module is valid, practical, and effective in improving students' literacy skills in biodiversity material.

Abstract

This study aims to make and develop electronic worksheet students (E-LKPD) that can be used by teachers in implementing learning in using IT-based learning media. This type of research is research and research and development (R&D) with a 4D development model (Define, Design, Development, and Dissemination). The sample in this study was biology teachers and students of SMA Negeri 1 Kaliorang. The results of the validation of media, material, and language experts respectively are 84.41% (very feasible), 82.35% (very feasible), and 69.41% (feasible). The results of the Biology Teacher Repson related to product practicality obtained a percentage of 92.50% (very practical), while the results of the trial to see the response of students obtained a percentage of 82.50% (very practical). The results of the effectiveness test using the paired sample t-test test showed that there was an effect of the use of canva-based e-LKPD in improving the learning outcomes of high school students in East Kutai on biotechnology material

Abstract

Serangan hama seperti ini berkontribusi pada penurunan produksi kangkung (Ipomoea reptans Poir) di daerah Berau Belalang Kukus Hijau (Atractomorpha crenulate), Belalang Kumbara (Locusta migratoria), Ulat grayak (Plutella xylostella) dan Kepik kaki daun (Leptoglossus gonagra) yang menyebabkan daun layu dan berlubang. Studi semacam ini merupakan eksperimen yang dilakukan di lahan pertanian Jalam Tabalar Muara RT. 02, Kecamatan Tabalar, Kabupaten Berau memakai lima perlakuan dalam desain blok acak (RAK), termasuk T0 (kontrol), T1 (kombinasi ekstrak daun sukun dan daun kacapiring wangi 25%), T2 ((kombinasi ekstrak daun sukun dan daun kacapiring wangi 40%), T3 (kombinasi ekstrak daun sukun dan daun kacapiring wangi 55%), dan T4 (kombinasi ekstrak daun sukun dan daun kacapiring wangi 70%) dengan 5 pengulangan. Hasil analisis data Fhitung perlakuan secara berturut-turut sebesar (7,858) ˃ F blok dengan taraf penting 1%. Pengakajian data menunjukkan bahwa pemberian ekstrak daun sukun memiliki dampak yang signifikan. (Artocarpus altilis) dan kacapiring wangi (Gardenia jesminoides Ellis) tentang seberapa parah tanaman kangkung (Ipomoea reptans Poir) diserang oleh hama.
