Dragon fruit plants originating from Central and South America have not been widely cultivated. This plant has only been cultivated intensively in several countries such as: Israel, Colombia, Nicaragua, Vietnam, Thailand, China and Australia. Macroscopic identification showed that the fungi associated with dragon fruit stems had similarities to the colony form of Colletotrichum gloeosporioides sp. Trichoderma is known to have antagonistic abilities against pathogenic fungi. Trichoderma is easily found in soil ecosystems and plant roots. The method in this study is a survey method. Determination of the sample using purposive sampling or Judgmental sampling method, namely purposive sampling is a sampling method that selects objects (vines) that are considered attacked or have symptoms of pathogen attack. Trichoderma sp is also tolerant to stress and able to inactivate pathogenic microbial enzymes. In addition, Trichoderma sp. Able to produce enzymes that hydrolyze pathogenic cell walls which will inhibit the synthesis of pathogenic cell walls and increase their fungicidal activity, as a result of which pathogenic fungi experience a decrease in growth rate.

Peningkatan efektivitas kelompok tani sebagai unit produksi sangat dipengaruhi oleh kemampuan anggota kelompoknya dalam menjalin kerja sama yang kuat. Kohesivitas kelompok menjadi indikator penting dalam keberhasilan kelompok untuk menjalankan fungsinya sebagai unit produksi pada usahatani padi sawah. Penelitian ini bertujuan menganalisis tingkat kohesivitas kelompok tani serta faktor-faktor yang memengaruhinya, dengan kebaruan yang terletak pada penggunaan enam variabel psikososial yang diuji secara simultan pada konteks kelompok tani padi sawah di Kecamatan Sunggal. Penelitian dilaksanakan pada Maret–Mei 2025 menggunakan metode deskriptif kuantitatif melalui penyebaran kuesioner dan wawancara tidak terstruktur, serta dianalisis menggunakan skala Likert dan regresi linear berganda. Hasil penelitian menunjukkan bahwa kohesivitas berada pada kategori tinggi (78,46%), dengan persamaan regresi Y = 4,702 + 0,170X1 + 0,430X2 + 0,946X3 – 0,350X4 + 0,560X5 + 0,552X6 + e. Persamaan tersebut menunjukkan bahwa interaksi sosial (X2), tujuan kelompok (X3), konflik kelompok ((X5), dan peran dalam kelompok (X6) terbukti berpengaruh signifikan, sedangkan untuk ketertarikan anggota (X1) dan ukuran kelompok (X4) tidak berpengaruh signifikan. Temuan ini menegaskan bahwa kualitas interaksi, kejelasan tujuan, manajemen konflik, dan pembagian peran merupakan faktor kunci yang memperkuat kohesivitas kelompok tani dalam menjalankan fungsi unit produksi usahatani padi sawah.

Information Technology and Communication played a important role in the execution of tasks by the Agricultural Extension and Research Agency (BPP). BPP Air Sijorman, located in Asahan Regency, was previously without a website. A community service initiative was undertaken to design a website for BPP Air Sijorman, serving as a platform for agricultural extension and the dissemination of information. The process commenced with socialization and the identification of system needs, followed by website design, implementation, and user training. The website was conceptualized using CorelDRAW and physically designed by aligning the graphics with the source code on the website. The implemented system resulted in the creation of the BPP Air Sijorman website, which was accessible via both desktop and mobile devices at http://bpp-airjoman.website/beranda.html. The website offered information on farming guidelines, the latest news, agricultural policies, and the BPP profile, accessible through various menus. The response from both BPP and farmers to the BPP Air Sijorman website was highly positive. On average, participants in the training sessions demonstrated the ability to operationalize and effectively use the website. Participants also expressed satisfaction with the website's visually appealing design, user-friendly interface, informative content, simplicity, and easily understandable instructions. This positive feedback underscored the effectiveness of the implemented website, making it a valuable tool for agricultural extension and information dissemination.

Desa Kota Datar, Kecamatan Hamparan Perak, Kabupaten Deli Serdang merupakan salah satu wilayah yang memiliki potensi pengembangan komoditas hortikultura, khususnya mentimun. Namun petani masih bergantung pada penggunaan pupuk kimia secara berlebihan sehingga dapat meningkatkan biaya produksi dan menurunkan kualitas lahan dalam jangka panjang. Di sisi lain, ketersediaan sumber daya lokal berupa kotoran burung puyuh dan bonggol pisang yang berpotensi dapat dimanfaatkan sebagai pupuk organik. Oleh karena itu, kegiatan penyuluhan ini bertujuan untuk meningkatkan pengetahuan petani mengenai pemanfaatan kotoran burung puyuh dan pupuk organik cair bonggol pisang pada budidaya mentimun. Kegiatan dilaksanakan melalui metode ceramah, diskusi, pemaparan cara pembuatan, serta melaksanankan evaluasi menggunakan pretest dan posttest terhadap 35 orang petani. Hasil kegiatan menunjukkan bahwa penyuluhan mampu meningkatkan pemahaman petani mengenai manfaat, cara pembuatan, dan aplikasi pupuk organik. Petani juga memberikan respon positif serta menunjukkan minat untuk menerapkan teknologi yang diperkenalkan. Pemanfaatan kotoran burung puyuh dan pupuk organik cair bonggol pisang diharapkan dapat mengurangi ketergantungan terhadap pupuk kimia, menekan biaya usahatani, meningkatkan produktivitas tanaman, serta mendukung penerapan sistem pertanian yang ramah lingkungan dan berkelanjutan.

This study was motivated by the high dependence of farmers on inorganic fertilizers, which may reduce soil fertility, and the underutilization of organic wastes such as goat urine, pineapple peels, and banana peels as liquid organic fertilizer (LOF). The objectives of this study were to analyze the effect of LOF derived from goat urine, pineapple peels, and banana peels on the growth and yield of watermelon (Citrullus lanatus), determine the optimum application rate, and evaluate farmers' acceptance and adoption of the technology. The study was conducted from March to May 2026 in Sei Bamban District, Serdang Bedagai Regency, using a non-factorial Randomized Complete Block Design (RCBD) consisting of five treatments and five replications. The treatments were P0 (control), P1 (50 ml + 20 ml), P2 (100 ml + 35 ml), P3 (150 ml + 50 ml), and P4 (200 ml + 65 ml). Observed variables included vine length, number of leaves, flowering age, fruit weight, fruit length, and fruit diameter at harvest (55 days after planting). Data were analyzed using analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) at the 5% significance level, while extension effectiveness was evaluated through pre-test and post-test assessments. The results indicated that the application of liquid organic fertilizer significantly affected all growth and yield parameters of watermelon. Treatment P4 produced the best vegetative growth and yield compared with the other treatments. Extension activities also improved farmers' knowledge, attitudes, and adoption of the technology. Therefore, liquid organic fertilizer derived from goat urine, pineapple peels, and banana peels has the potential to serve as an effective, environmentally friendly, and sustainable alternative fertilizer for watermelon cultivation. Keywords: banana peel, goat urine, liquid organic fertilizer, pineapple peel, watermelon.
