Effects of Azolla pinnata Compost and Carbonate Lime (CaCO₃) on Soil Chemical Properties, Nitrogen Uptake, and Yield Components of Sweet Corn Grown in Ultisols
Get PDFUltisols, covering approximately 705,151 hectares in Bengkulu, represent a marginal soil type with considerable agricultural potential. However, they are limited by low nutrient availability, low pH, low organic carbon, and high concentrations of exchangeable aluminum (Al) and iron (Fe). These constraints significantly affect the growth and productivity of crops such as sweet corn, which is sensitive to acidic conditions and nutrient deficiency. Soil fertility improvement through organic matter application and liming is a promising approach. Azolla, an aquatic fern with high nitrogen content due to its symbiosis with Anabaena azollae, was used in composted form. This study aimed to determine the optimum application rates of Azolla compost and carbonate lime (CaCO₃) for improving nitrogen up take, growth, and yield of sweet corn in Ultisols. The treatments consisted of four Azolla compost levels (0, 5, 10, and 15 tons ha-1) and three lime rates equivalent to neutralizing 0, 1, and 2 units of exchangeable Al. A factorial experiment was arranged in a completely randomized design with three replications. Data were analyzed using analysis of variance (ANOVA), followed by orthogonal polynomial testing. Azolla compost significantly improved soil pH, organic carbon content, stem diameter, plant height, ear weight, biomass (fresh and dry), and nitrogen uptake. Lime applica tion significantly increased soil pH, stem diameter, and plant height. No significant interaction occurred between the two factors. Although positive responses were observed, the yield remained below the potential of the Bonanza F1 variety, likely due to high rainfall and suboptimal treatment levels. These findings support the integration of Azolla compost and lime into soil fertility management practices for sustainable sweet corn production on acidic tropical soils.

KONSTRUKSI GURU BERDIKARI DALAM KARYA BERBASIS ARTIFICIAL INTELEGENT(AI) DI ERA TEKNOLOGI
Get PDFRegulation of the Minister of State Apparatus Empowerment and Bureaucratic Reform (Permen PANRB) No. 16 of 2009, dated 10 November 2009, concerning Functional Positions of Teachers and Their Credit Points, states that one aspect related to literacy activities is creating works of art. In this case, artistic works take the form of literary works in the form of narrative stories (prose). Narrative storytelling is one way to train social sensitivity. This can be drawn from everyday themes. From observations of teachers, it is evident that most teachers have a desire to work and educate more freely. However, they are still limited in expressing their ideas comprehensively and to the fullest extent. Several obstacles include: 1) a lack of comprehensive understanding of the nature of literary works, including prose, 2) a lack of sensitivity in capturing the relics of life as ideas and sources of stories, and 3) a lack of motivation in creative work, in this case, digital screenwriting. Given these problems, the practical solution and objective of this community service programme are to assist in utilising artificial intelligence (AI) to create works, enabling teachers to be more independent in their work. The artificial intelligence (AI) referred to here is Canva, Noveltoon, Capcut, and TikTok. This community service programme is in collaboration with e-guru.id. With the broad reach of the e-guru platform, it is hoped that this training will increase the capacity and improve literacy among teachers in Indonesia. This aligns with the Ministry of Education and Culture's Content Creator Teacher programme. In addition, teachers' skills can also be utilized to introduce various Ministry of Education and Culture programs and expand independence in teaching and learning, which requires a broader distribution of literacy.Peraturan Menteri Pendayagunaan Aparatur Negara dan Reformasi Birokrasi (Permen PANRB) No. 16 Tahun 2009 tanggal 10 November 2009 tentang Jabatan Fungsional Guru dan Angka Kreditnya menyatakan bahwa salah satu aspek yang berkaitan dengan kegiatan literasi adalah menciptakan karya seni . Karya seni dalam hal ini berbentuk karya seni sastra yang berupa cerita naratif (prosa). Bercerita secara naratif merupakan salah satu cara untuk melatih kepekaan sosial. Hal itu dapat diangkat dari tema-tema keseharian.Dari observasi pada guru-guru, sebagian besar guru memiliki keinginan berkarya dan mendidik dengan lebih bebas. Namun, masih terbatas untuk menuangkan gagasannya secara menyeluruh, komprehensif, dan maksimal. Beberapa hal yang menjadi kendala, antara lain: 1) kurangnya pemahaman yang utuh tentang hakikat karya sastra, termasuk prosa, 2) kurangnya kepekaan dalam menangkap relik-relik kehidupan sebagai gagasan dan sumber cerita, 3) Kurangnya motivasi dalam kerja kreatif, dalam hal ini mengekranisasi dalam bentuk digital. Dari permasalahan tersebut, solusi praktis sekaligus tujuan dari pengabdian ini adalah melakukan pendampingan pemanfaatan Artificial Intelligence (AI) untuk menciptakan karya sehingga guru dapat berdikari dalam berkarya. Artificial Intelligence (AI) yang dimaksud berupa canva, noveltoon, capcut, dan TikTok. Pengabdian ini bekerja sama dengan e-guru.id. Dengan luasnya keterjangkauan platform e-guru, diharapkan pelatihan ini, mampu menambah kapasitas dan peningkatan pembudayaan literasi pada guru-guru di Indonesia. Hal ini sejalan dengan program Kemendikbud Guru Konten Kreator. Selain itu, keterampilan guru juga kelak dapat digunakan untuk mengenalkan berbagai program Kemendikbud dan memperluas kemerdekaan dalam belajar mengajar diperlukan distribusi literasi yang lebih luas.
