Enhancing the Efficiency and Productivity of Sustainable Agriculture on Former Tin Mining Land: A Case Study in the Bangka Belitung Islands, Indonesia

The utilisation of biological resources, food ingredients, industrial raw materials, and environmental management within the agricultural sector influences gross domestic product in Indonesia. This research addresses the challenge of improving sustainable agricultural efficiency by reducing resource waste and increasing productivity. The study aims to analyse improvements in agricultural efficiency based on the optimal amounts of water, fertiliser, and pesticides required for plant growth, thereby minimising costs and improving crop quality. The research location was situated on former tin mining land owned by farmers in Desa Sinar Baru Jelutung, Bangka Regency, Bangka Belitung Islands Province, Indonesia. Data collection took place from August 2024 to December 2024. The study employed nutrient sensors, water and soil pH measurements, solar cells, NPK fertiliser, sinusoidal waves, and copper wire in the research process. Drying, grinding, and sieving analyses were conducted to ensure laboratory testing accuracy. Results indicated an average weight of 1,000 rice grains of 39.5 grams for electroculture plots, compared to 26 grams for control plots. Electroculture demonstrably increased the dry grain weight by approximately 51.92% relative to the control group, showing its potential to improve rice production efficiency. Findings from the electroculture treatment resulted in a higher average grain weight and greater variability, attributed to factors such as soil nutrient distribution and environmental condition variations. Conversely, the control group yielded more stable results but tended towards lower values. The percentage increase in weight shows the extent to which electroculture technology can improve crop yields compared to conventional methods.
