Abstract

The main objective of this study was to determine the profile of endogenous intestinal bacteria of yellowfin tuna, Thunnus albacares that can function as potential probiotics in the digestive system and used for the maintenance of yellowfin tuna larvae. Wild yellowfin tuna, T. albacares was collected from the waters of Gerokgak, Buleleng, North Bali, Indonesia. Intestinal bacteria were isolated, identified, characterized, and followed by enzymatic hydrolysis activity tests, antagonistic tests and pathogenicity tests to select candidate bacteria as probiotics. The results of the enzymatic hydrolysis activity test showed that there were 4 isolates of candidate probiotic bacteria that were active in enzymatic synthesis for amylase, lipase, casease, lecithinase, gelatinase. Identification through Sanger sequencing resulted in 4 potential bacterial isolates as probiotics, namely Bacillus subtillis strain T-A1, Bacillus amyloliquefaciens strain T-N2, Bacillus subtillis strain T-O4, and Paraclostridium bifermentans strain T-O6. These four bacteria were not antagonistic between varieties and were not pathogenic in Tuna fish. Yellowfin tuna fed probiotic supplements grew faster (5.5002 ± 0.2 mm) than the control (4.9002 ± 0.4 mm). The success of yellowfin tuna seed production is expected to be sustainable and its implementation in the private sector for aquaculture purposes.

Abstract

Training and assistance in the creation of scientific articles based on artificial intelligence (AI) aims to improve the scientific writing skills of prospective teachers at Mandalika Education University. The program involves the use of AI-based tools such as ChatGPT to correct grammar and Scite AI to help participants find relevant references quickly. A total of 25 students of the Faculty of Science, Engineering, and Applied participated in this training online. The method used in this activity involves three main stages, namely preparation, training, and mentoring. In the preparation stage, the training materials are designed to cover important topics related to scientific writing, the use of AI-based tools, and reference management using Mendeley and Zotero. The training was carried out in the form of interactive sessions, where participants were given material on the structure of scientific articles, the use of AI tools, and reference management techniques. Mentoring is carried out individually to provide more specific feedback on the articles that have been compiled by the participants. The results of the evaluation showed a significant improvement in the participants' ability to understand the structure of scientific articles using academic language, and to manage references appropriately. Despite the challenges associated with academic integrity and reliance on technology, this training provides a solid foundation for aspiring teachers to integrate technology in scientific writing and teaching.

Abstract

This article aims to examine the importance of internalising the values of Siddiq (honesty) and Amanah (responsibility) as the foundation for innovation in Islamic education in the digital age, particularly in shaping the character of students. The method used is a conceptual approach through literature analysis of Islamic education studies, prophetic character, and the concept of teacherpreneurship of the Prophet Muhammad SAW as a role model for modern teachers. The results of the study show that the value of Siddiq serves as the foundation of academic integrity in the digital learning process, while the value of Amanah serves as an ethical guideline in the professional responsibility of teachers towards the use of technology. The integration of these two values confirms that Islamic educational innovation rooted in prophetic spirituality is able to balance technological progress with the cultivation of noble character in students.
