<![CDATA[Provinsi Jambi memiliki hutan hujan tropis dataran rendah yang mengalami deforestasi tercepat di daerah Asia. Efek dari perubahan alih fungsi hutan ke habitat pertanian akan mengubah kondisi ekosistem. Hal tersebut diduga berpengaruh pada keanekaragaman makroinvertebrata di dalamnya. Kesalahan identifikasi morfologi dapat disebabkan oleh fenomena cryptic species maupun siblings species. Fenomena tersebut dapat menyebabkan masalah sinonim yaitu terdapat nama ganda pada satu spesies yang sama. Untuk menyelesaikan permasalahan tersebut dapat digunakan teknik DNA Barkode. Penelitian ini bertujuan untuk mengidentifikasi dan memastikan spesies udang air tawar yang berasal dari provinsi Jambi dengan mengaplikasikan teknik DNA barcoding.Berdasarkan identifikasi morfologi didapatkan 3 sampel terdiri dari satu famili. Berdasarkan analisis COI gene, 2 spesies berhasil diidentifikasi yaitu Macrobrachium malayanum dan M. pilimanus. Satu spesies sampel target yaitu M. malayanum 1 terbukti sebagai spesies M. malayanum yang sesuai dengan data GenBank. ]]>

<![CDATA[Digital education is an activity that monitors developments in the digital world in everyday life. increase literacy, develop critical thinking abilities and skills. Digital education functions as a digital reference for students to guide their learning activities. The aim of this research is to reviewing one of the digital learning resources for students. The research design uses high-quality literature from mature articles. proceedings, which are currently available on Google Scholar for 2019–2022. The research results show that the use of GPT chat as a reference source for learning students' intellectual tasks. Additionally, many GPT Chat user interface issues were also mentioned. In education, this applies to both positive and negative damping contributions. GPT chat is useful for learning, especially as a substitute for one of the digital learning resources for students.]]>

<![CDATA[The learning process is monotonous and lacks media and facilities inadequate learning will affect learning outcomes and ways of thinking students. Evaluation is part of the process that is used as a rejection. Lecturer evaluation by giving grades and completeness predicates to students contributes greatly and must be updated along with development factors. One of them is digital evaluation. During the process, learning is evaluated to have found a method that is efficient, acceptable, and makes students enthusiastic and able to complete the next assignment to attract students' interest. This can be achieved by applying technology as a new tool for assessing learning. Researchers achieved research that uses a systematic literature review method, which aims to identify effective digital learning evaluation methods in various journals and research journals on educational evaluation. Next, literature from various databases is interpreted and a review is made about the use and success of digital evaluation media for students and teachers in learning statistics through applications or the web. Therefore, research findings suggest that digital evaluation tools can increase students' interest and desire to learn and use them to greatly help lecturers interactively deliver lessons.]]>

<![CDATA[Penicillin acylase from the genus Bacillus plays an irreplaceable role as a key catalyst in the modern antibiotic era. This enzyme essentially facilitates the production of 6-aminopenicillanic acid (6-APA), a vital precursor for various semisynthetic beta-lactam antibiotics that continue to be the mainstay in the fight against bacterial infections. The aim of this study was to review Bacillus Penicillin Acylase: A Key Catalyst in the Modern Antibiotic Era," a literature review. This method is a more rigorous and structured approach than a traditional literature review. The goal is to minimize bias and provide a reliable and comprehensive synthesis of research relevant to a specific research question. The expected findings, based on our previous discussions and general knowledge of the field, are as follows: A literature review on "Bacillus Penicillin Acylase: A Key Catalyst in the Modern Antibiotic Era" would likely yield a comprehensive overview of the enzyme's significance, characteristics, production, and applications. The review would highlight how important Bacillus-derived penicillin acylase is for making 6-aminopenicillanic acid (6-APA). 6-APA is always pointed out as the key building block for creating many types of semisynthetic beta-lactam antibiotics, which are essential for today's antibacterial treatments. Different types of bacteria and even different strains of the same type show differences in their enzymes, such as what substances they work best with (like penicillin G or V), how active they are, the best conditions for them to work (like pH and temperature), how stable they are, and whether they produce the enzyme inside or outside the cell.]]>

<![CDATA[This research started from the problem of low student learning outcomes on the virus learning material, evidenced by the below-standard quiz scores. Therefore, the learning outcomes were not as expected. This research aims to know the implementation of biology learning in senior high school, which includes the design, implementation, and assessment of learning. The research informants were teachers of biology and Senior high school students. This type of research is descriptive with a qualitative approach. Based on the findings, it can be concluded that (1) the teachers are not contextually planning the learning. (2) The teachers are not effectively and efficiently implementing the learning due to (a) the lack of effective time utilization, (b) the lack of ability to establish and select instructional media appropriate to the criteria of the learning material, and (c) the poor quality of laboratory equipment. (3) The teachers assess student learning outcomes despite the incorrect procedures. ABSTRAK: Penelitian ini berawal dari permasalahan rendahnya hasil belajar siswa. Hal ini terbukti dari hasil kuis siswa yang berada dibawah (KKM) sehingga nilai Biologi tidak sesuai yang diharapkan. Penelitian ini bertujuan untuk mengetahui implementasi Pedagogik guru dan hasil pembelajaran biologi di SMAN Bukit sundi yang meliputi implementasi dan penilaian hasil pembelajaran. Informan dalam penelitian ini adalah guru biologi, siswa kelas X. Jenis penelitian deskriptif dengan pendekatan kualitatif. Berdasarkan temuan hasil penelitian tersebutterlihat (1) Guru tidak merencanakan pembelajaran secara kontekstual dengan konteks pembelajaran dilaksanakan. (2) Guru yang menerapkan pembelajaran belum efektif dan efisien karena: (a) Guru belum memanfaatkan waktu secara efektif, (b) Guru belum dapat menetapkan dan memilih media pembelajaran (c) pembelajaran belum efektif karena terbatasnya peralatan laboratorium. (3) Guru melakukan penilaian hasil belajar dengan prosedur yang belum tepat.]]>
