Abstract:
This study uses the Nutrient Film Technique (NFT) hydroponic system to grow and produce
green lettuce (Lactuca sativa) to determine the impact of POC kipahit and AB Mix on those processes. Five
treatments were used in this study's Completely Randomized Design (CRD. Each treatment was repeated four
times, with five net pots, one for each replication containing lettuce plants. The hydroponic installation used in
this research uses a 21-inch pipe. The pipe is designed to be an NFT system with a pipe slope of 2–10%,
consisting of five holes with a distance between holes of 10 cm. Next, the NFT hydroponic installation was set
up in the experimental area, with each installation having a nutrient tank attached and marked for each
treatment. The acquired data was examined quantitatively, and analysis of variance (ANOVA) and tests of
means were performed using Duncan's Multiple Range Test (DMRT) at the 5% level to verify whether the
treatments were significantly different. SPSS 20 and Microsoft Excel were used for data processing and analysis.
Using the NFT hydroponic system, the POC kipahit and AB Mix supply significantly impacted the development
and production of green lettuce. A concentration combination of POC kipahit and AB Mix that can increase
the growth and production of green lettuce compared to the use of 100% AB Mix has not yet been obtained.
