Abstract

Ubi kayu atau singkong tumbuh di berbagai daerah dan jenis tanah. Produktivitas ubi kayu bervariasi antar daerah karena perbedaan varietas dan lingkungan. Curah hujan yang rendah pada kondisi bulan kering menyebabkan cekaman kekeringan pada pertumbuhan ubi kayu. Penelitian ini bertujuan untuk mengetahui respons tiga varietas ubi kayu yang diberi irigasi sebagai simulasi pada kondisi bulan kering. Ubi kayu ditumbuhkan dalam media polibag dalam rumah kaca di Kebun Percobaan Cikabayan, IPB Bogor. Tiga varietas ubi kayu Mangu, Genjah Bayam, dan IR Jonggol ditanam dan disiram pada 98.1 mL per hari per polibag (setara curah hujan 60 mm per bulan) dan 130.8 mL per hari per polibag (setara curah hujan 80 mm per bulan). Tidak ada pengaruh interaksi varietas dan penyiraman tanaman terhadap variabel pertumbuhan ubi kayu. Variabel pertumbuhan ubi kayu berbeda antara varietas dan penyiraman tanaman. Pada umur 12 minggu setelah tanam (MST), tinggi tanaman Genjah Bayam lebih rendah dibandingkan varietas lainnya. Mangu memiliki jumlah lobus terbanyak pada 8 MST, bobot dari batang, tangkai daun, dan daun varietas Mangu paling tinggi. Penyiraman 130.8 mL per hari per polibag menghasilkan tinggi tanaman, jumlah daun menempel, diameter batang, tangkai daun, dan tinggi tanaman berdaun lebih tinggi daripada 98.1 mL per hari per polibag. Kata kunci: curah hujan rendah, interaksi, kekeringan, respons pertumbuhan, singkong

Abstract

Hydroponics is a modern plant cultivation system without soil to produce clean, healthy, and fresh vegetables. The availability of fresh, healthy food is a key factor in preventing stunting. This community service activity aims to increase food security and prevent stunting through vegetable cultivation using hydroponic technology. Methods used include socialization, training, practice, mentoring, monitoring, and evaluation of hydroponic technology and its processing. Results show that partners experienced increased empowerment, with knowledge of hydroponics and its processing improving by >30 percent. Partner skills in producing hydroponic vegetable products significantly improved, transitioning from no prior experience to being skilled at hydroponic cultivation, with increased production. This activity also yielded various vegetables (water spinach, spinach, bok choy, and Chinese kale) grown using hydroponic systems. Additionally, DFT hydroponic system facilities with a capacity of 200 plants per installation (4 installations) and processing tools were provided, enabling the community to access fresh, nutritious food and support stunting prevention.

Abstract

The use of synthetic herbicides is an effective way to control weeds, but their widespread use has negative environmental impacts. A bioherbicide made from purple nutsedge tubers can be an alternative for weed control. Purple nutsedge’s tuber contain allelopathy compounds that can inhibit the growth of other plants (weeds). This study aims to evaluate the response of various shapes and sizes of bioherbicide granules made from purple nutsedge’s tuber in suppressing the germination of weed seeds and crop seeds. The experiment used a completely randomized design one factor and eleven treatments: control without herbicide treatment, synthetic herbicide active ingredient oxyfluorfen 240 g/L, purple nutsedge’s tuber powder bioherbicide without carrier, very small round granule bioherbicide, small round granule, medium round granule, large round granule, very small cylindrical granule, small cylindrical granule, medium cylindrical granule, and large cylindrical granule. Each treatment was tested on four species: Bidens pilosa and Cynodon dactylon (weeds), cucumber, and rice (crops). The experimental results showed that the application of purple nutsedge’s tuber-based bioherbicides exerts a noticeable influence on several germination parameters. The smaller the bioherbicide granule, the higher the germination inhibition rate. Very small, round-shaped granule bioherbicides showed greater effectiveness in suppressing seed sprout percentage, reducing growth rate, increasing the percentage of abnormal sprouts, and inhibiting plumula and radicle growth.
