Abstract

This study aimed to explore and identify endophytic bacteria from katuk plants (Sauropus androgynus L.) and evaluate their potential as biological control agents. A total of 14 bacterial isolates were successfully obtained from the roots, stems, and leaves of katuk plants. Safety assessments were conducted through hypersensitivity response (HR) and hemolysis (HL) tests. The HR test on tobacco plants indicated that all isolates were non-pathogenic, as no necrotic symptoms were observed. However, the hemolysis test revealed two isolates capable of forming α-hemolysis zones on blood agar, suggesting potential risks to mammals. Antibacterial activity against the plant pathogen Ralstonia solanacearum was evaluated using spot inoculation methods. The results showed that none of the isolates were able to inhibit the growth of R. solanacearum. Although the isolates may produce antibacterial compounds, the amounts are likely insufficient or involve unidentified active compounds. Further studies are needed to fully characterize these isolates and explore their potential applications in sustainable agriculture.

Abstract

Kemampuan mahasiswa dalam mencari dan memanfaatkan literatur ilmiah sangat berpengaruh terhadap kualitas karya akademik mereka. Google Scholar hadir sebagai salah satu solusi efektif yang memberikan akses ke berbagai literatur akademik secara gratis. Selain mendukung mahasiswa, Google Scholar juga berperan dalam meningkatkan H-Index dosen sebagai salah satu indikator kinerja utama (IKU) institusi pendidikan tinggi. Artikel ini mendeskripsikan kegiatan workshop pengabdian masyarakat yang dirancang untuk memperkenalkan Google Scholar kepada mahasiswa Fisika Universitas Negeri Makassar (UNM). Kegiatan ini terdiri atas pelatihan teori dan praktik yang bertujuan untuk meningkatkan literasi akademik, efisiensi manajemen referensi, dan reputasi institusi. Hasil pelatihan menunjukkan peningkatan signifikan pada pemahaman mahasiswa dalam mencari, mengelola, dan memanfaatkan literatur akademik. Selain itu, terdapat dampak langsung pada H-Index dosen melalui optimalisasi strategi publikasi. Dengan pendekatan partisipatif, kegiatan ini memberikan kontribusi nyata terhadap peningkatan kualitas penelitian di lingkungan akademik.

Abstract

Education is a conscious effort to develop the potential of human resources (HR) through teaching activities. To be able to create conducive teaching and learning activities and be able to develop effective learning outcomes is the task and obligation of teachers as educators. Therefore, teachers directly try to influence, foster and develop students' abilities to become intelligent and skilled people. In essence, practicums are proof of theory, students who refer to theory without any reinforcement through practicums, will The understanding obtained through practicums is usually more memorable and more lasting, because students are directly involved in practicum activities and can prove for themselves the theory given by the teacher. Therefore, the Physics Education Laboratory Assistant Team intends to carry out an activity entitled Student Laboratory Work Application (AKLAM) at the Al-Fityan School Gowa Integrated Islamic Junior High School (SMPIT) - Gowa Regency, which is designed as a creative response to increasing wise values ​​towards educational professionalism towards learning situations. This activity was carried out for four days of implementation by assisting the Head of the Laboratory and the Science Laboratory Manager to improve and complete the administration related to the laboratory. Able to improve students' knowledge about global warming symptoms, junior high school physics practicum, coordination of school practicum equipment data collection, and completion of school laboratory administration as well as improving the quality of practicum learning of the Physics Education laboratory assistant team at UIN Alauddin Makassar S-1 level to comply with national education standards in order to improve the quality of education for Physics Education students of the Faculty of Tarbiyah and Teacher Training, UIN Alauddin Makassar in the future.

Abstract

This study aimed to isolate and evaluate the biological safety and potential of endophytic bacteria from Sauropus androgynus (katuk) and their Chitinolytic activity for use as biological agents. A total of 14 endophytic bacterial isolates were obtained from different plant parts: 5 from the roots (T1, T2, T3, T4, P14), 5 from the stems (T7, T8, T9, T10, T11), and 4 from the leaves (T5, P6, KB12, T13). The safety of these isolates was assessed through hypersensitivity (HR) and hemolysis (HL) tests. In the HR test, none of the isolates induced necrotic symptoms in tobacco leaves, indicating they are not pathogenic to plants. In the HL test, two bacterial which were T4 from roots and T5 from leaves, isolates were found to produce clear zones on blood agar, indicating α-hemolysin production. However, the other isolates did not form hemolysis zones, suggesting they are safe for mammals. Antibacterial activity against the plant pathogen Ralstonia solanacearum was evaluated using spot inoculation methods. The results showed that none of the isolates were able to inhibit the growth of R. solanacearum. Further testing revealed that one bacterial isolate which was T8 obtained from the stem produced chitinase, as evidenced by the formation of a clear zone around the bacterial colony on chitin-containing media.
