Abstract

Penelitian ini merupakan jenis penelitian pengembangan R&D (Research And Development) yang bertujuan untuk (1) mengembangkan modul berbasis riset untuk mata kuliah Biologi Terapan dan (2) mengevaluasi validitas modul yang telah dikembangkan. Pendekatan penelitian yang digunakan adalah pendekatan kualitatif deskriptif dan kuantitatif. Model pengembangan modul yang digunakan adalah model 4D yang terdiri dari empat tahap, yaitu pendefinisian (define), perancangan (design), pengembangan (develop), dan penyebaran (disseminate). Namun, dalam penelitian ini, penyusunan modul hanya mencakup tahap pengembangan (develop). Teknik pengumpulan data menggunakan metode kuisioner berupa lembar angket validasi modul. Subyek penelitian terdiri dari tiga orang tim validator ahli dan sepuluh orang mahamahasiswa untuk uji coba terbatas. Berdasarkan analisis data yang telah dilakukan, diperoleh hasil validitas modul oleh tim validator ahli dengan rata-rata 85,41% untuk komponen kelayakan isi dengan kriteria kevalidan baik, 83,33% untuk komponen bahasa dengan kriteria kevalidan baik, dan 84,09% untuk komponen penyajian dengan kriteria kevalidan baik. Rata-rata validitas modul oleh tim validator ahli adalah 84,27% dengan kriteria kevalidan baik. Selain itu, hasil validitas uji coba terbatas oleh sepuluh orang mahamahasiswa menunjukkan persentase sebesar 87,62% dengan kriteria kevalidan baik. Dengan demikian, dapat disimpulkan bahwa modul yang dikembangkan dengan judul "Potensi Antosianin Kulit Terong Ungu (Solanum melongena)" layak digunakan pada mata kuliah Biologi Terapan. Validity of Research-Based Applied Biology Module on the Concept of Utilizing Purple Eggplant Peel Anthocyanin as a Biosensor  This research is a type of R&D (Research And Development) development research which aims to (1) develop research-based modules for Applied Biology courses and (2) evaluate the validity of the modules that have been developed. The research approach used is a qualitative descriptive and quantitative approach. The module development model used is the 4D model which consists of four stages, namely define, design, develop, and disseminate. However, in this study, the preparation of the module only includes the development stage (develop). The data collection technique uses a questionnaire method in the form of a module validation questionnaire sheet. The research subjects consisted of three expert validator teams and ten students for limited trials. Based on the data analysis that has been done, the module validity results were obtained by a team of expert validators with an average of 85.41% for the content feasibility component with good validity criteria, 83.33% for the language component with good validity criteria, and 84.09% for presentation component with good validity criteria. The average module validity by the expert validator team is 84.27% with good validity criteria. In addition, the results of the limited trial validity by ten students showed a percentage of 87.62% with good validity criteria. Thus, it can be concluded that the module developed under the title "Anthocyanin Potency of Purple Eggplant (Solanum melongena) Skin" is suitable for use in Applied Biology courses.

Abstract

This study aims to determine the morphological and growth characteristics of Eisenia foetida in response to mushroom waste media. Two types of mushroom waste media were used: straw mushroom media waste and oyster mushroom baglog waste. The research design was experimental, using quantitative methods and descriptive statistical analysis. The study observed parameters such as body length, body weight, skin color, population, and biomass of Eisenia foetida. The results showed significant differences in the growth and morphological characteristics of Eisenia foetida among the various media treatments. The oyster mushroom waste media with higher composition (80%) yielded better growth in terms of body weight and biomass compared to the straw mushroom waste media. Specifically, the treatment with 80% oyster mushroom waste and 20% straw mushroom waste (P3) showed the highest average body weight (17.13 g).  In conclusion, mushroom media waste, especially oyster mushroom baglog waste, supports the optimal morphological development and growth of Eisenia foetida. These findings suggest that oyster mushroom waste can be effectively utilized as a medium for cultivating Eisenia foetida, providing an environmentally friendly solution to organic waste management. Recommendations for future research include exploring other types of organic waste as potential media for Eisenia foetida cultivation and conducting long-term studies to evaluate the sustainability of such media.
