Abstract

Bioteknologi adalah cabang ilmu Biologi yang mempelajari pemanfaatan makhluk untuk menghasilkan produk yang dapat digunakan oleh manusia. Materi bioteknologi disajikan oleh guru disekolah dengan menggunakan media pembelajaran yang tersedia. Menurut peserta didik, media pembelajaran yang digunakan sudah lengkap namun peserta didik masih sulit memahami materi karena penjelasan yang panjang. Peserta didik dan guru membutuhkan media tambahan yang dapat menyajikan gambar dalam bentuk audio visual sebagai penunjang dalam proses pembelajaran. Penelitian menggunakan model pengembangan 4-D dengan menerapkan 3 dari 4 tahap pengembangan 4D, yaitu define, design, dan develop. Uji validitas dilakukan oleh tiga orang dosen Biologi FMIPA UNP dan satu orang guru Biologi SMA. Aspek yang dinilai pada uji validitas yaitu  kelayakan isi, kebahasaan, penyajian dan kegrafikaan. Hasil uji validitas menunjukkan bahwa booklet digital yang dikembangkan mendapatkan nilai 95,59% dengan kriteria sangat valid. Dengan hasil tersebut, booklet digital bioteknologi terintegrasi Eco-Enzyme layak digunakan sebagai bahan ajar digital Biologi.

Abstract

Background: Ecoenzymes, created from the fermentation of organic citrus waste, offer a sustainable method to produce Indole Acetic Acid (IAA), a phytohormone vital for plant growth. This study investigates the potential of these ecoenzymes in promoting sustainable agriculture. Objective: This study aims to evaluate the capacity of ecoenzymes derived from local citrus organic waste to synthesize IAA hormones. Methods: The ecoenzyme was extracted from fruit powders and centrifuged to separate the supernatant. One ml of ecoenzyme supernatant was then mixed with 2 ml of Salkowski reagent and incubated for 12 hours at room temperature in the dark to facilitate reaction. The presence and concentration of IAA were determined using spectrophotometry at a wavelength of 530 nm, while total protein levels were measured using the Warburg-Christian method. Results: ecoenzymes from local citrus sources contain IAA, with the highest concentration observed in sample 7A (30.26 µg/ml). The ecoenzyme exhibited favorable characteristics, including an average degree of acidity of 3.55, and the highest total protein content was found in sample 2A (144.277 mg/mL). Conclusion: Ecoenzymes from local orange peels successfully produce IAA, supported by fermentation-induced microbial activity and acidic conditions. This highlights their potential in sustainable agriculture.

Abstract

Biodiversity is Indonesia's natural wealth. Nagari Tanjung Balik, IX Koto Atas District, Solok Regency is a Nagari that has unique natural wealth. Ngalau is part of the wealth of Biodiversity that must be preserved. However, this area has received less attention because it has not been properly promoted. This is because the ability of residents to introduce their area through various platforms is still lacking. For this reason, it is necessary to have YouTube-based community multimedia production training. The form of activity that will be carried out is active participation through promotional strategy seminars, multimedia production training, and promotional videos as well as the use of YouTube as a village promotion media. The results of these activities resulted in 3 best video winners. The satisfaction survey showed that 58% of participants were very satisfied and 42% satisfied. Improvements in knowledge, attitudes and skills were also seen after the activity.
