The production of pak choy (Brassica rapa L) based on cleaner coffee production

The environmental damage that is happening in Indonesia is getting bigger. Industrial activity waste is becoming more and more and creates pollution. The waste reduction process strategy can be done by collaborating, between agronomic technical applications and clean production. The purpose of this writing shows that the clean production process in the coffee industry can be collaborated through the development of healthy vegetables through the use of coffee waste after processing it into by-products (compost and liquid ertilizer). Hope can provide knowledge and an overview for the coffee farming community on how to apply this clean production concept to their industry. The production process is clean through energy efficiency and will ultimately result in minimization of useful waste again. The experiment used a randomized design. Treatment groups consisted of: the first composition (NPK compound fertilizer + Nasa liquid fertilizer + coffee compost); The second composition (NPK compound fertilizer + coffee waste liquid fertilizer + coffee compost); The third composition (liquid Nasa fertilizer + coffee waste liquid fertilizer + coffee compost). Growth variables consisted of plant height, number of leaves and leaf width; Production variables consist of weight I plant and weight I plot. The results obtained by the utilization of coffee production waste (coffee husk compost and coffee waste liquid fertilizer) are recommended to support clean coffee production, able to increase Pak Choy's (Brassica rapa L) production per sample and area
