Abstract

Program Pengabdian Masyarakat ini dilaksanakan pada bulan September 2023 di Laboratorium Kultur Jaringan, Jurusan Biologi, FMIPA UNM, dengan sasaran utama Guru Biologi dan IPA di Provinsi Sulawesi. Metode yang digunakan mencakup penyampaian teori, demonstrasi, latihan pembuatan media, sterilisasi spesimen (eksplan), penanaman, serta diskusi dan sesi tanya jawab. Penyampaian teori bertujuan untuk memberikan pemahaman dasar mengenai kultur jaringan tumbuhan. Demonstrasi dilakukan agar peserta dapat mengamati langsung prosedur dan tahapan sterilisasi serta pembuatan medium dan eksplan. Praktik dimaksudkan agar peserta memperoleh keterampilan dalam melaksanakan proses kerja kultur jaringan. Diskusi dan sesi tanya jawab dirancang untuk mengatasi masalah yang muncul selama penyampaian teori dan kegiatan praktik. Berdasarkan kegiatan ini, dapat disimpulkan bahwa pelatihan ini berhasil meningkatkan pemahaman dan keterampilan guru dalam melaksanakan praktikum kultur jaringan menggunakan bahan dan peralatan sederhana dengan biaya rendah. Program ini membekali guru-guru dengan keterampilan untuk melaksanakan praktikum dengan mudah di laboratorium sekolah.

Abstract

Fusarium wilt, caused by Fusarium oxysporum (Fo), is a major disease affecting potato plants (Solanum tuberosum L.) and contributes significantly to yield losses. This study aimed to isolate and identify antagonistic bacteria from the potato rhizosphere capable of inhibiting the growth of F. oxysporum and to assess their antifungal potential through in vitro analysis. Soil samples were collected from the potato-growing region of Kanreapia, Gowa Regency, Indonesia. The antagonistic potential of the bacterial isolates was evaluated using the dual-culture assay. A total of eight bacterial isolates demonstrated significant inhibitory effects against Fo, representing six genera: Clostridium (75.0%), Bacillus (69.3% and 68.9%), Pseudomonas (67.9% and 62.1%), Staphylococcus (64.8%), Neisseria (64.7%), and Serratia (61.5%). Among these, the isolate identified as Clostridium exhibited the highest inhibition rate (75.0%), while Serratia showed the lowest (61.5%). These findings suggest the potential application of rhizobacteria as biological control agents for managing Fusarium wilt in potatoes.

Abstract

Students' low understanding of complex human digestive and excretory system materials shows a gap in the use of technology-based interactive learning media in high school/MA. This study aims to develop and evaluate the validity, practicality, and effectiveness of Articulate Storyline-based interactive media for learning the human digestive and excretory system in grade XI using the ASSURE design model. The research innovation lies in the integration of interactive multimedia technology with the ASSURE systematic learning approach which includes student analysis, goal setting, media-method selection, material utilization, and evaluation-revision. The research and development (R&D) method was applied with the subjects of grade XI high school/MA students. Data was collected through pretests, user response questionnaires, and expert validation. The results showed that the developed media achieved very high validity (> score of 0.80), excellent practicality of teacher and student assessments (81-100%), and significant effectiveness with an average N-Gain of 0.7227 indicating a substantial improvement in learning outcomes. These findings indicate that the Articulate Storyline interactive media with the ASSURE design is effective in improving understanding of complex biology concepts, making a significant contribution to technology-based science learning innovations in Indonesia, and has the potential to be widely applied for a more engaging and effective transformation of biology education.
