Hydroponics is rapidly gaining traction as an innovative farming method, and Ahmad Rofi, a 26-year-old farmer from Kedawung Village, Padang District, Lumajang, East Java, has proven its potential. By utilizing a 250-square-meter greenhouse next to his home, he cultivates lettuce with a system that requires no soil, minimal water, and careful monitoring.
From Unproductive Land to Green Profits
Ahmad’s journey began with a simple observation: much of the land around his home was unproductive and underutilized. Inspired to make a difference, he adopted hydroponic farming, which allowed him to maximize output even on limited land. Hydroponics, a soil-free cultivation method, involves growing plants in a nutrient-rich water solution. This system is especially beneficial in areas with limited fertile land.
Key Metrics of Success
Ahmad’s hydroponic operation yields impressive results:
- Yield: Producing up to 230 kilograms of lettuce per month.
- Harvest Time: Lettuce is ready for harvest in 35–40 days, making it a relatively quick and consistent crop.
- Price: The lettuce sells for IDR 35,000 per kilogram.
- Income: Monthly profits reach up to IDR 6 million, after deducting operational costs.
Hydroponic Techniques and Maintenance
To ensure optimal growth, Ahmad closely monitors the pH levels of the water and provides nutrients in precise quantities. The controlled environment of the greenhouse protects the crops from pests, diseases, and adverse weather conditions. This systematic approach results in consistent, high-quality produce.
Market and Expansion
Ahmad supplies his hydroponic lettuce to various cafes and restaurants in Lumajang. The increasing demand for fresh, locally sourced vegetables has contributed to the success of his venture. Ahmad is exploring options to expand his greenhouse to scale production and meet the growing market needs.
The Broader Implications of Hydroponics
Hydroponics offers a sustainable solution to several challenges faced by modern agriculture, such as limited arable land, water scarcity, and climate unpredictability. Farmers like Ahmad serve as role models, demonstrating that innovation and resourcefulness can transform small-scale farming into a lucrative business.
Ahmad Rofi’s story is a testament to the potential of hydroponic farming in addressing land productivity challenges and providing stable incomes. With careful planning, monitoring, and market engagement, hydroponics can pave the way for a more sustainable and profitable agricultural future.
