Inhibition of Cellulase Activity Fusarium oxysporum f. sp. lycopersici Pathogens in Tomato Plants Using Essential Oils from Citronella in Vitro
No full textThe purpose of this study is to determine the ability of essential oils from citronella plants to inhibit cellulase enzyme activity in the fungus Fusarium oxysporum f. sp. lycopersici. and evaluate its potential as a disease-control material in tomato plants. This research was carried out in August 2023 until completed in February 2024. The method used in this study is experimental which consists of the process of exploring the fungus that causes disease in tomato plants, microscopic characterization of fungal isolates, molecular identification, inhibition test of fungal colony growth using essential oils from citronella plants, cellulase enzyme activity test, and cellulase enzyme activity inhibition test using essential oils from citronella plants. The variables observed in this study consisted of inhibiting the growth of Fusarium oxysporum f. sp. lycopersici. By essential oils, test the activity of quantitative cellulase enzymes, and cellulase enzymes activity inhibition test using essential oil from citronella plant. The results of microscopic characterization and molecular tests show that the fungal isolate used in this study has 99% similarity with Fusarium oxysporum f. sp. lycopersici. Essential oils extracted from citronella plants effectively inhibit the formation of fungal colonies. This is evidenced by the results of observation at the age of 7 HSI mushrooms with the growth diameter of fungal colonies of 5.06 cm, 3.56 cm, and 2.44 cm after applying essential oils with concentrations of 333 ppm, 666 ppm, and 1000 ppm. Results of observation and calculation of cellulase enzyme activity values in Fusarium oxysporum f. sp. lycopersici isolate. Cellulase enzyme activity of 0.831 U/mL was obtained. The application of essential oils with sequential concentrations (333 ppm, 666 ppm, and 1000 ppm) was able to decrease the activity of cellulase enzymes, with activity inhibition of 31%, 39%, and 44% in Fusarium oxysporum f. sp. lycopersici isolates
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
PENGARUH FERMENTASI CAIRAN RUMEN TERHADAP PROFIL NUTRISI ECENG GONDOK (Eichhornia crassipes) SEBAGAI PAKAN IKAN NILA (Oreochromis niloticus)
Full text linkTujuan penelitian ini adalah untuk mengetahui komposisi nutrisi eceng gondok yang telah mengalami fermentasi dengan cairan rumen. Durasi penelitian ini adalah satu bulan, tepatnya Juli 2019 hingga Agustus 2019. Proses fermentasi dilakukan di Fakultas Pertanian Universitas Muhammadiyah Makassar. Laboratorium Kimia dan Pakan Ternak Fakultas Peternakan Universitas Hasanuddin melakukan analisis kimia. Penelitian ini menggunakan rancangan acak lengkap, dengan tiga perlakuan yang masing-masing diulang sebanyak tiga kali, sehingga menghasilkan total sembilan unit penelitian. Individu yang menjalani pengujian diberikan perlakuan berikut: Perlakuan A melibatkan dosis 10 mL cairan rumen, Perlakuan B melibatkan dosis 15 mL cairan rumen, dan Perlakuan C melibatkan dosis 20 mL cairan rumen. Berdasarkan hasil analisis, eceng gondok dapat dimanfaatkan sebagai komponen pakan ikan dengan memasukkan cairan rumen sebagai bahan fermentasi alami. Kandungan nutrisinya dapat ditingkatkan dengan memberikan cairan rumen sebanyak 20 mL pada 500 gram eceng gondok
Unpacking the Impact of the Merdeka Mengajar Platform on Teacher Performance: A CIPP Model Evaluation
Full text linkThis study evaluates the implementation of the Platform Merdeka Mengajar (PMM) and its impact on improving teacher performance through the Context, Input, Process, and Product (CIPP) evaluation model. As a flagship initiative of Indonesia’s Ministry of Education, PMM provides self-paced training modules, instructional resources, assessment tools, and digital portfolios to support teachers in delivering the Merdeka Curriculum. Employing a qualitative approach, data were collected through semi-structured interviews, classroom observations, and document analysis involving eight teachers and one principal at a junior secondary school in Indonesia. The findings indicate that PMM is contextually aligned with the evolving needs of educators, particularly in promoting independent learning and responsive teaching. While infrastructure and resources were generally adequate, limited digital fluency and time constraints hindered optimal use. Teachers are actively engaged with the platform, supported by institutional mechanisms like Komunitas Belajar, for collaborative reflection. The evaluation showed improved pedagogical competence, classroom management, and student engagement. Despite some obstacles, PMM demonstrates strong potential as a digital innovation for professional development. This study recommends sustained policy support, user-centered platform improvements, ongoing training, and a robust monitoring and evaluation framework to enhance its effectiveness. The results provide valuable insights for policymakers and school leaders seeking to integrate technology into teacher development systems
