Abstract

Potato production in North Sumatra is productive compared to other provinces with a yield of 124 326 tons in 2020. To continue to improve the quality and quantity of potato harvest each year, continuous innovation is needed in implementing agricultural systems and technologies that can increase productivity. This research aims to find agrotechnology that can increase productivity by focusing on developing the quality of soil as farming land in Kuta Rayat Village, Naman Teran District, Karo District, North Sumatra Province. Potato agrotechnology was studied through plot trials using the Randomized Block Design method with 7 treatments (agro-potato: mounds across the slope, quality seeds, lime dosage, manure and chemical fertilizer according to the recommendations given). Data collected included before and after treatment of soil properties and potato productivity. The results of this study showed that the dose of Dolomite lime 1.5 tons/ha, manure 20 tons/ha, 150 kg Urea, 150 kg ZA, 250 kg SP-36 and 200 kg KCl was sufficient to obtain optimal potato productivity and improve soil quality.

Abstract

The increase in the price of animal feed makes it difficult for households as farmers by utilizing household waste to feed their livestock. The increase in feed prices also encourages food farmers to switch to corn because corn is a raw material for animal feed. So that household farmers also have difficulty buying corn. Maggot BSF is an alternative feed that is very high in protein to encourage livestock growth. BSF maggots are larvae that can be used as alternative feed. Cultivation of BSF maggot is also relatively easy and can utilize household waste or food scraps as BSF maggot food. In this community service, training activities for maggot cultivation as an alternative to animal feed are carried out in Bane Village. The implementation method is carried out by means of lectures, discussions and practice. The result of this service is to grow the participants' desire to cultivate BSF maggot as animal feed. The result was that the participants were very responsive to this activity, as evidenced by the active participation of the community in the activity from beginning to end and the large number of active participants in the discussion and question and answer sessions. So it can be concluded that the maggot cultivation training in Bane Village was successful and the participants' understanding and attitudes increased about the importance of waste treatment for maggot cultivation as an alternative to animal feed

Abstract

This study examines the acceleration of agricultural recovery following the Sibolga flash flood, which severely affected household food systems. It aims to synthesize scientific evidence on effective food-security-based agricultural recovery strategies using a Systematic Literature Review (SLR) approach. The research data were drawn from relevant scientific literature published within the past five years on agricultural recovery, household food security, and flash floods. The findings indicate that successful recovery is determined by a combination of technical, social, and institutional interventions that strengthen farmers’ resilience capacities. In conclusion, accelerating agricultural recovery requires an integrative, community-based strategy that combines socioecological dimensions with public policy to build resilient and sustainable household food systems in disaster-prone areas.

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh dosis pupuk NPK Mutiara 16.16.16 dan pupuk kandang ayam terhadap pertumbuhan serta produksi tanaman lobak (Raphanus sativus L.). Kegiatan dilaksanakan di Desa Huta Tano, Kecamatan Silimakuta, Kabupaten Simalungun (±1.412 mdpl) pada Oktober–Desember 2024 menggunakan Rancangan Acak Kelompok (RAK) faktorial 3×3 dengan tiga ulangan. Faktor pertama adalah NPK 16.16.16: N1 = 250 kg/ha (25 g/plot), N2 = 300 kg/ha (30 g/plot), N3 = 350 kg/ha (35 g/plot). Faktor kedua adalah pupuk kandang ayam: A1 = 5 ton/ha (0,5 kg/plot), A2 = 10 ton/ha (1,0 kg/plot), A3 = 15 ton/ha (1,5 kg/plot). Peubah yang diamati meliputi tinggi tanaman (3, 5, 7 MST), jumlah daun (5, 7, 9 MST), panjang dan diameter umbi, bobot umbi per tanaman, serta bobot umbi per plot. Data dianalisis dengan ANOVA RAK faktorial pada α = 5% dan uji lanjut yang sesuai. Hasil menunjukkan bahwa baik NPK 16.16.16 maupun pupuk kandang ayam memberikan pengaruh nyata terhadap tinggi tanaman, jumlah daun, panjang dan diameter umbi, bobot umbi per tanaman, serta bobot umbi per plot. Dosis tertinggi NPK (N3: 35 g/plot) secara konsisten menghasilkan nilai pertumbuhan dan hasil paling tinggi; demikian pula dosis tertinggi pupuk kandang ayam (A3: 1,5 kg/plot). Interaksi N×A tidak berpengaruh nyata pada seluruh peubah, meskipun kombinasi N3A3 umumnya memberikan nilai maksimum (misalnya tinggi 7 MST, diameter, dan bobot umbi). Temuan ini menegaskan pentingnya pemupukan berimbang—mengombinasikan sumber hara anorganik dan organik—serta merekomendasikan NPK 35 g/plot dan pupuk kandang ayam 1,5 kg/plot sebagai dosis operasional untuk mengoptimalkan produktivitas lobak pada kondisi agroekologi penelitian.
