Abstract

Bawang merah (Allium ascalonicum L.) merupakan komoditas hortikultura yang konsumsi dan permintaannya sangat tinggi di masyarakat. Namun, data menunjukkan bahwa produksi bawang merah dari tahun ke tahun terus mengalami perubahan, yang seringkali memicu fluktuasi harga dan ketergantungan pada impor di beberapa periode. Penelitian ini bertujuan untuk menguji dosis pupuk serta penggunaan giberelin (GA3) pada tiga varietas bawang merah untuk mengoptimalkan produktivitas bawang merah secara berkelanjutan dan efisien. Penelitian dilakukan pada bulan Mei sampai Agustus 2025 di Desa Pancot, Tawangmangu, Karanganyar dengan ketinggian tempat 1200 mdpl. Rancangan  penelitian menggunakan Rancangan Petak Terbagi (Split Plot) dan diulang sebanyak 3 (tiga) kali. Petak utama merupakan varietas bawang merah, sedangkan anak petak merupakan dosis pupuk + giberelin. Data dianalisis dengan ANOVA menggunakan uji F pada taraf signifikansi 5%. Jika ditemukan perbedaan yang signifikan, analisis dilanjutkan dengan uji Duncan’s Multiple Range Test. Hasil penelitian menunjukkan bahwa, substitusi 50% pupuk  anorganik ke pupuk organik yang dikombinasikan dengan giberelin 50ppm mampu meningkatkan jumlah anakan per rumpun (7,22), jumlah umbi per rumpun (8,33) dan berat kering umbi per rumpun (58,96 g). Shallots (Allium ascalonicum L.) are a horticultural commodity with consistently high consumption and demand. However, production data reveal frequent fluctuations, often leading to price instability and reliance on imports during certain periods. This research aimed to determine fertilizer dosages and gibberellic acid (GA3) application for three shallot varieties to optimize their productivity sustainably and efficiently. The study was conducted from May to August 2025 at the Pancot Village, Tawangmangu, Karanganyar, located at an elevation of 1200 meters above sea level. A Split-Plot Design was employed with three replications. Shallot varieties constituted the main plots, while combinations of fertilizer dosage and GA3 formed the sub-plots. Quantitative data were analyzed using analysis of variance (ANOVA) at a 5% significance level (F-test). When significant differences were detected, Duncan's Multiple Range Test (DMRT) was used for post-hoc comparisons. The results demonstrated that the application of 50 ppm gibberellic acid, combined with a fertilizer dosage of 50% inorganic + 150% organic, significantly increased the number of shoots per clump (7,21), number of bulbs per clump (8,33), and productivity per clump (58,96).

Abstract

Chrysanthemum (Chrysanthemum spp.) is an important floricultural commodity in Indonesia. However, its production is seriously threatened by white rust caused by Puccinia horiana. Conventional control still depends on synthetic fungicides, which pose risks of pathogen resistance and environmental contamination. The use of biological control agents (BCAs) offers an environmentally friendly and sustainable alternative within the framework of Integrated Pest Management (IPM). This review summarizes current studies on the use of Pseudomonas fluorescens, Bacillus subtilis, Trichoderma spp., and Cladosporium spp. for managing white rust in chrysanthemum. The main mechanisms include antibiosis, parasitism, competition for space and nutrients, and induced systemic resistance (ISR). Research shows that BCAs can suppress P. horiana infection and improve plant growth, although their effectiveness varies depending on environmental conditions, formulation stability, and farmer adoption. Future research should focus on locally adapted isolates, improved formulation technology, and multilocation trials to ensure field consistency. Policy support and farmer participation are also essential to expand the use of BCAs and promote sustainable chrysanthemum production.

Abstract

The incorporation of digital media into early literacy learning is the main emphasis of this research, which examines digital literacy methods and techniques for improving children's early reading abilities. The study examined Scopus-indexed papers released between 2015 and 2025, utilizing a methodical literature review based on the PRISMA 2020 framework, and used the Watase Uwake tool to evaluate the use of digital literacy in early childhood education. Eight of the 133 identified articles satisfied the inclusion criteria for comprehensive analysis. According to the results, interactive digital media like augmented reality, digital storytelling, and instructional apps greatly aids in the early childhood development of reading comprehension, vocabulary, and phonological awareness. But the success of these digital interventions depends heavily on teachers' willingness to incorporate technology into the curriculum and on parents' active role in directing their children's digital experiences. In particular, there are research gaps pertaining to the roles of parental support and teacher readiness, particularly in the Indonesian setting. This study offers fresh perspectives on the integration of digital literacy into early reading instruction and emphasizes the need for cooperation between educators, parents, and legislators in order to create a positive learning environment. In order to guarantee the successful integration of technology into early childhood education both in Indonesia and throughout the world, the practical implications highlight the need for focused teacher training programs to improve their digital literacy. To get the most out of digital literacy for early reading development, these results highlight the necessity of a comprehensive strategy that includes all parties

Abstract

Fusarium wilt disease is a serious threat to the banana agribusiness system, significantly reducing production efficiency starting from the nursery phase. This study aimed to evaluate the efficacy of biological control agents (Streptomyces and Bacillus) in suppressing the progression of the pathogen Fusarium oxysporum f. sp. cubense (Foc) and enhancing the growth of 'Ambon' banana seedlings through in planta assays. The experiment employed a completely randomized design with nine combinations of isolates. The results demonstrated that the application of bio-agents significantly reduced disease progression and improved the physiological quality of the seedlings. The consortium of Streptomyces S01 and Bacillus B16 exhibited the highest biocontrol efficacy, recording a disease intensity of 38.88% and the lowest area under disease progress curve value. Meanwhile, the combination of Streptomyces S01 and Bacillus B01 produced the optimal plant height of 60.22 cm. Notably, the endophytic isolate Bacillus B16, applied individually, maintained root weight comparable to healthy, uninfected seedlings. Economically, integrating these antagonistic microbes offers a more efficient and sustainable nursery system by reducing reliance on chemical inputs.
