ANALISIS RISIKO USAHATANI BAWANG MERAH

Yoel Melsaro Larosa — 2025-11-03

This study aims to analyze the level of production and price risk in red onion farming, as well as to examine the behavior of red onion farmers in Tiganderket Village, Tiganderket Subdistrict, Karo Regency. The main focus of the study is to understand the extent of the risks faced by farmers in red onion production and how their decisions and willingness to take risks influence farming practices. The sample was determined using a census method, where the entire population of red onion farmers in the study area was used as respondents, totaling 15 individuals. Primary data were collected through surveys and direct interviews, ensuring that the information reflects the actual conditions in the field. Data analysis was conducted using multiple linear regression to determine the influence of several variables on production and price risk levels. The results showed that the production risk in red onion farming in Tiganderket Village is considered high, indicated by a coefficient of variation of 0.52, which exceeds the threshold of 0.5. Conversely, the price risk is relatively low, with a coefficient of variation of 0.02, well below the threshold. Furthermore, the behavior of farmers in facing risks is also considered high; all respondents, 100%, demonstrated a willingness to take risks in red onion farming practices. These findings indicate that although red onion production carries a high level of risk, farmers still exhibit proactive behavior and a willingness to make risky decisions, while price fluctuation risks are relatively low. Therefore, economically, red onion farming can still be carried out with a reasonable degree of certainty. These results can serve as a basis for developing agricultural strategies and supportive policies for red onion farmers in Karo Regency.

INTEGRATION OF MODERN SOIL SCIENCE, INTEGRATED FARMING, AND NIAS LOCAL WISDOM FOR AGRICULTURAL PRODUCTIVITY IMPROVEMENT

Darmawan Harefa — 2025-11-03

This study explores the integration of modern soil science, integrated farming systems (IFS), and Nias local wisdom to improve agricultural productivity in Desa Bawonifaoso, Kecamatan Teluk Dalam, Kabupaten Nias Selatan. The research aims to examine how combining scientific soil management practices with diversified farming techniques and traditional knowledge can enhance crop yields, environmental sustainability, and community resilience. Using a qualitative literature review approach, data were collected from scientific journals, books, conference proceedings, and credible online sources that discuss soil fertility, integrated farming, and the application of local wisdom in agriculture. The findings indicate that modern soil science interventions such as soil testing, rational nutrient management, and organic amendments can optimize soil fertility and crop growth. When applied alongside integrated farming practices and local wisdom traditions, such as communal land management, crop rotation aligned with cultural calendars, and organic residue utilization, farmers achieve higher yields, reduced dependency on chemical inputs, and improved environmental sustainability. Furthermore, integrating these approaches strengthens community engagement and knowledge transfer, ensuring sustainable adoption. The study concludes that the tripartite integration of modern soil science, IFS, and local wisdom offers a holistic, culturally appropriate, and environmentally sustainable model for agricultural development. It is recommended that agricultural extension programs and policymakers support this integrated approach to enhance productivity, resilience, and food security in rural Indonesian communities.

PENGARUH PEMANGKASAN CABANG DAN BEBERAPA JENIS VARIETAS TERHADAP PERTUMBUHAN TANAMAN CABAI MERAH (CAPSICUM ANNUM L) DI DESA NANOWA

This study aimed to determine the effect of branch pruning and several varieties on the growth of red chili plants. The research was conducted at the Agrotechnology practicum field. A randomized block design (RBD) with two factors was used: the first factor consisted of two varieties, V1 (TM999) and V2 (Lado F1), while the second factor included three levels, namely P0 (no treatment), P1 (field-top pruning), and P2 (side-shoot pruning). Each treatment consisted of five plants. The observed data were analyzed using analysis of variance (ANOVA) and followed by an LSD test at a 5% significance level. The results showed that branch pruning significantly affected the vegetative growth of red chili plants in almost all observed parameters. Plant height exhibited a consistent response at all observation periods (1–4 WAP), the number of leaves showed a significant response after the initial adaptation phase (3–4 WAP), and stem diameter increased significantly at 4 WAP.

RESPON PEMBERIAN ABU SABUT KELAPA DAN PUPUK KCL TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN BAWANG MERAH

Yanema Waruwu — 2025-11-30

Shallot (Allium ascalonicum L.) is one of the leading vegetable commodities that has long been cultivated intensively by farmers. The application of coconut husk ash and KCl fertilizer in shallot cultivation is considered necessary to enhance its productivity. This study aimed to evaluate the response of coconut husk ash and KCl fertilizer on the growth and yield of shallot. The research was conducted at the Agrotechnology Practicum Field, located in Nanowa Village, Teluk Dalam District, South Nias. The experiment was arranged in a factorial randomized block design (RBD), with each factor consisting of three treatment levels and three replications, resulting in nine treatment combinations. Observed parameters included plant height, number of leaves, number of tillers, bulb weight, and bulb number. Data were analyzed using analysis of variance (ANOVA), followed by the Least Significant Difference (LSD) test. The LSD results showed that the interaction of coconut husk ash and KCl fertilizer had no significant effect on either the growth or yield parameters of shallot. The combination treatments of coconut husk ash and KCl fertilizer did not significantly influence shallot performance. The highest values were obtained at the treatment level A0K0 (without coconut husk ash + 300 kg/ha KCl).

PENGARUH PUPUK KANDANG AYAM DAN PUPUK NPK TERHADAP PERTUMBUHAN TANAMAN JAGUNG MANIS (Zea mays L.)

Santria Melsin Susanti Laia — 2025-11-30

Penelitian ini bertujuan untuk mengetahui pengaruh pupuk kandang ayam dan pupuk NPK terhadap pertumbuhan jagung manis (Zea mays L.). Penelitian dilaksanakan di Desa Nanowa pada Maret–Agustus 2025 dengan menggunakan Rancangan Acak Kelompok (RAK) dua faktor. Faktor pertama adalah pupuk kandang ayam dengan tiga taraf: A0 (tanpa perlakuan), A1 (10 ton/ha = 0,8 kg/plot), dan A2 (20 ton/ha = 1,6 kg/plot). Faktor kedua adalah pupuk NPK dengan tiga taraf: N0 (tanpa perlakuan), N1 (100 kg/ha = 80 g/plot atau 20 g/tanaman), dan N2 (150 kg/ha = 120 g/plot atau 30 g/tanaman). Setiap unit percobaan terdiri dari empat tanaman, sehingga total keseluruhan 108 tanaman. Data dianalisis dengan sidik ragam dan dilanjutkan uji BNT 5%. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, dan umur berbunga. Hasil penelitian menunjukkan bahwa dosis A2 (1,6 kg/plot) memberikan hasil terbaik, sedangkan interaksi kedua faktor tidak berpengaruh nyata.
