It operates under the open-access model and is peer-reviewed, allowing researchers from around the world to access and contribute to its content.</p> <p align="justify">The journal was initially published semi-annually by The East Java Biological Society and was formerly in the Indonesian language. The first edition was Vol 1 No 1 in June 1995. Over the years, it has evolved and gained recognition in the academic community. In 2023, articles published three times a year, in April, August, and December, with an average of ten articles per issue. There is a record of journal accreditation:</p> <ol start="1" data-spread="false"> <li class="show"> <p>The Ministry of Culture and Education from 2001 to 2011 (accreditation number: 134/DIKTI/Kep/2001)</p> </li> <li class="show"> <p>The Ministry of Research and Higher Education for the period of 26 April 2017 to 26 April 2022 (accreditation number: 32a/E/KPT/2017)</p> </li> <li class="show"> <p>The Ministry of Education, Culture, Research, and Technology for 2022-2026 (Volume 28 (1) April 2022 to Volume 32 (2) August 2026 with accreditation number: 79/E/KPT/2023)</p> </li> </ol> <p align="justify">Since 2011, the journal has been indexed by Zoological Record by Thomson Reuters Clarivate Analytics, adding to its reputation and visibility in the scientific community. Moreover, in April 2012, the journal transitioned from publishing in the Indonesian language to publishing exclusively in English, making its content accessible to a broader international audience.</p> <p align="justify">Berkala Penelitian Hayati covers a wide range of topics in the field of biology, and it encourages the submission of original research, applied research, review articles, and educational articles. Authors are invited to submit authentic and unpublished works, not currently under review in other journals, ensuring the integrity and novelty of the content.</p> <p align="justify">The journal's scope includes but is not limited to the following areas of study: botany, zoology, ecology, microbiology, physiology, nanobiology, coastal biology, hydrobiology, neurobiology, genetics, developmental biology, biochemistry and molecular biology, biophysics, and other life sciences-related topics.</p> <p align="justify">Berkala Penelitian Hayati is available in online versions which is freely accessible and allows readers to download articles for easy access to the latest scientific research in the life sciences.</p> <p align="justify">The journal is indexed in various reputable databases, including DOAJ, Crossref, Google Scholar, Academia.edu, and EBSCO Host, ensuring that researchers and scholars can easily find and cite the published articles.</p> <h3>Founding and Historical Background</h3> <p align="justify">Prof. Drs. Bambang Irawan M.Sc., Ph.D., a Professor in the field of Population Biology and Carsinology at the Faculty of Science and Technology (FST), Airlangga University, initiated the publication of the journal in 1995. At that time, the journal was managed manually, including typing and printing. His contributions laid the foundation for the journal's growth and continued development as a significant platform for biological research dissemination.</p> <p align="justify">During that period, much research data in Indonesia was primarily presented in seminars and rarely documented or published in journals. The high costs associated with scientific journal publication, including editorial expenses and communication between authors and editors via postal services, posed significant challenges. Additionally, the availability of national journals was very limited. Recognizing these challenges, the need for an accessible and structured scientific publication led to the establishment of Berkala Penelitian Hayati.</p> <p align="justify">Overall, Berkala Penelitian Hayati serves as a valuable platform for researchers to share their findings, advancements, and knowledge in the diverse and ever-evolving field of biology.</p> https://berkalahayati.org/index.php/jurnal/article/view/963 2026-08-08T17:57:24+00:00 Egidi Octavia Mahardhani 21025010024@student.upnjatim.ac.id Felicitas Deru Dewanti fderu_d@upnjatim.ac.id Juli Santoso julisantoso@upnjatim.ac.id

<p>Shallot production declined due to suboptimal cultivation and fertilization practices. The Tajuk variety had high yield potential but wass prone to premature flowering. GA₃ and humic acid played a role in enhancing growth and productivity. This study aimed to evaluate the effect of GA₃, humic acid, and their combination on shallot growth and yield to determine the optimal concentration. The study was conducted from May to August 2025 in Jeruk Purut Village, Pasuruan (±350 m above sea level). The split-plot design consisted of 16 treatment combinations and three replicates. The treatments consisted of GA₃ (0, 200, 300, and 400 ppm) and humic acid (0, 200, 300, and 400 ml/L). Growth and yield parameters were analyzed using ANOVA and the 5% HSD test when significant effect were observed. The combination of 300 ppm GA₃+ 300 ml/L humic acid provided the best growth and yield. Individually, 300 ppm GA₃ and 300 ml/L humic acid were the most effective in increasing plant height, tuber weight, and biomass. Regression analysis showed a weak relationship, with GA₃ being negatively correlated and humic acid being positively correlated with fresh tuber weight.</p>
