Abstract

Apomecyna saltator, a notorious pest of honey pumpkin plants, poses a significant threat to both vegetative and generative phases, leading to considerable production losses. Despite its agricultural impact, there are limited studies on effective management strategies for this pest. This research investigates the effect of combined phosphorus and potassium fertilization on controlling A. saltator infestations in honey pumpkin plants. The study was conducted at the Teaching and Research Farm of the Faculty of Agriculture, Jambi University. A randomized block design with five treatments and five replications was used, testing different combinations of SP-36 phosphorus and potassium chloride (KCl) fertilizers: no fertilization (p0), SP-36 0.67 g/plant + KCl 1.25 g/plant (p1), SP-36 1.00 g/plant + KCl 1.88 g/plant (p2), SP-36 1.34 g/plant + KCl 2.51 g/plant (p3), and SP-36 1.67 g/plant + KCl 3.13 g/plant (p4). The variables observed included stem diameter, larval population, percentage of plant damage, number of attacked plant segments, fruit weight, and overall production. Data were analyzed using ANOVA and Duncan's Multiple Range Test (DMRT). The results indicated that combining phosphorus and potassium fertilizers significantly increased stem diameter, fruit weight, and yield while reducing larval populations, plant damage, and affected segments. The study demonstrates that phosphorus and potassium strengthen honey pumpkin plants and negatively impact A. saltator infestations. This research highlights a novel approach to pest control, showing that targeted fertilization promotes plant health and suppresses the honey pumpkin stem borer (A. saltator). This dual benefit of nutrient application provides a sustainable and efficient pest management strategy, offering a fresh perspective on integrated crop protection.

Abstract

Indonesia is the producer and exporter of palm oil in the world from 2008 - 2023. One of the challenges in managing plantations is pest attacks and plant diseases. The disease that is often found is fruit rot disease caused by the fungus Marasmiuspalmivorus which can reduce production by up to 25% with symptoms of fruit changing color to blackish brown, watery and rotting. One of the factors that influences the development of fruit rot disease is the microclimate (temperature and humidity) around the plant. Microclimate is closely related to plant spacing density. If the plant spacing is tight, the temperature around the plant will be lower and the humidity will be higher, which can trigger the development of fruit rot disease. The research was conducted at PT. Sumatra Jaya Agro Lestari (SJAL) 2 at a density of SPH 160 and SPH 200 which shows that disease intensity and yield loss is higher at SPH 200 where the average disease intensity is 25.13% based on the regression equation with an estimated yield loss of 14.12%. Meanwhile, SPH 160 average disease intensity was 14.33%, with an estimated yield loss of 8.28%. The t test shows that the intensity and percentage of fruit rot disease differ based on plant density.Key words: Oil palm, density, fruit rot, intensity and yield loss

Abstract

Plant Growth Promotion Fungi (PGPF) are fungi that live in the soil near plant roots or live in plants (endophytic fungi), can increase plant growth (biofertilizer), and protect plants from plant-disturbing organisms in the form of pests and plant diseases (biopesticides). Farmers often experience obstacles due to poor plant growth due to less fertile soil and dry soil, and decreased production due to pests and plant diseases. The objectives of this community service are introducing PGPF and its benefits for plants,  exemplifying PGPF multiplication techniques and PGPF addition techniques to plants, introducing sorghum and low-cost farming with high competitiveness. To achieve these objectives, the methods applied are: (1) PGPF socialization, (2) counseling on the benefits of PGPF as a biofertilizer and biopesticide, (3) plot demonstration. The results of the activity are (1) farmers in Kota Baru Village are able to multiply and add PGPF to the soil and plants, (2) farmers are able to apply sorghum cultivation techniques as a food material in order to diversify food and availability of animal feed in every environmental condition of the dry season and rainy season. All parts of the sorghum plant (seeds, leaves, stems) can be utilized, so there is no waste (zero wasted).

Abstract

Pembangunan pertanian tanaman pangan di Muaro Jambi meliputi padi dan palawija, disisi lain pengembangan tanaman serealia selain padi dan jagung sangat diharapkan untuk menunjang pengembangan diversifikasi pangan sebagai bahan alternatif untuk memenuhi kebutuhan pangan non beras. Tujuan pengabdian adalah memberdayakan petani dan peternak dalam mengembangkan tanaman sorgum sebagai bahan pangan dan pakan ternak. Untuk percapaian tujuan tersebut pendekatan yang diterapkan adalah (1) sosialisasi budidaya tanaman sorgum, (2) penyuluhan manfaat sorgum (3) demonstrasi plot. Metode yang digunakan dalam pengabdian ini adalah metode androgogy (pendidikan untuk orang dewasa), partisipasi aktif peserta (petani dan peternak) sangat diprioritaskan dalam rangka mengetahui potensi yang dimiliki dan meningkatkan motivasi. Materi disampaikan dalam bentuk ceramah, diskusi dan demonstrasi plot dan pascapanen sorgum. Sorgum dapat tumbuh pada tanah kurang subur pada musim kering, resiko kegagalan kecil, dapat diratun, dan biaya (input) relatif rendah, selain itu semua bagian tanaman sorgum (batang, daun, dan buah) dapat dimanfaatkan untuk berbagai keperluan bahan pangan dan pakan ternak, sehingga tidak ada limbah (zero wasted)

Abstract

Rendahnya produktivitas cabai merah (Capsicum annuum L.) disebabkan oleh banyak faktor, salah satunya gangguan penyakit yang disebabkan oleh cendawan, bakteri, dan virus. Tobacco mosaic virus (TMV) merupakan salah satu virus penting yang menyerang tanaman cabai. Untuk itu perlu dilakukan pengendalian. Salah satu alternatif pengendalian TMV dengan menggunakan kitosan yang dapat menginduksi ketahanan sistemik. Kitosan dapat diperoleh dari pengolahan limbah cangkang rajungan melalui proses deproteinasi, demineralisasi, dan deasetilasi. Penelitian ini bertujuan untuk mempelajari efektivitas kitosan asal cangkang rajungan dalam mengendalikan TMV pada tanaman cabai. Penularan virus dilakukan secara mekanis. Penelitian disusun dalam Rancangan Acak Lengkap dengan 8 perlakuan dan 4 ulangan. Variabel yang diamati yaitu periode inkubasi penyakit, intensitas penyakit, persentase penyakit, tinggi tanaman dan berat kering tanaman. Hasil penelitian diperoleh tanaman yang diberikan kitosan cangkang rajungan menunjukkan periode inkubasi terlama pada tanaman cabai sampai 23 hsi. Pemberian kitosan cangkang rajungan dapat memperlambat masa inkubasi penyakit. Pemberian kitosan cangkang rajungan mampu menekan intensitas penyakit hingga 43,59%. Tinggi dan berat kering tanaman yang diberi kitosan cangkang rajungan dan diinokulasi TMV lebih tinggi daripada kontrol sakit. Perlakuan benih direndam dan disemprot kitosan dari cangkang rajungan pada umur 2 minggu setelah tanam menunjukkan hasil terbaik pada seluruh variabel pengamatan.
