Pembelajaran Aplikasi Pengukur Kandungan Klorofil pada Daun Tanaman Padi (Oryza sativa L.)

Abstract

Rice is a staple food in Indonesia, so the demand will continue to increase along with the population growth. Rice cultivation in Indonesia is known for two planting systems, namely wet rice that requires water and dry rice planted in fields that do not require special irrigation. Several regions in Indonesia have types of dry rice, including the almost extinct Fakhaito or black rice from Nias Regency, with a plant age of six months until harvest. The productivity of dry rice is very low, affecting farmers' income due to suboptimal fertilization technology. The aim of this research is to provide learning to students using the SPAD-502Plus chlorophyll meter to detect the growth and health of dry rice plants from Nias. The research results show that treatment with liquid organic fertilizer correlates positively with leaf color, where the amount of chlorophyll is higher in very green rice leaves and vice versa, the amount of chlorophyll decreases in plants with reduced green matter. The use of the SPAD-502Plus chlorophyll meter, by measuring directly, is faster, non-destructive, comfortable, and does not disturb plant growth.
