Abstract

Variant of Coleus sp. in Indonesia is very low. Induced mutation by Ethyl Methane Sulphonate (EMS) is able to increase variant of Coleus sp.. EMS is a mutagen that is effective and efficient in causing mutations. In mutation breeding, the high variant usually occurs around LC50 (Lethal Concentration). The objective of this study were (1) to obtain the LC50 value and sensivity of coleus plants, and (2) to evaluate the response of plant growth and to obtain new variance of coleus used soak and drops by EMS application. The experiment was arranged in randomized complete block design with three replications in each coleus. The materials used two Coleus sp. shoot cuttings i.e., C. amboinicus Lour. and C. blumei the purple/green color and the red. The concentration of EMS consisted of 0.00, 0.50, 0.75, 1.00, and 1.25% with application soak method (100 minutes) and drops (3 drops pipette). The results showed that the LC50 value of C. amboinicus Lour. 5.86% (soak). The LC50 value of C. blumei the purple/green color was 0.69% (soak), 0.82% (drops) and the red color 0.29% (drops), 0.89% (drops). C. blumei (the purple/green and red) was higher sensitivity rather than C. amboinicus Lour. There was an interaction between treatments on C. amboinicus Lour. whereas C. blumei (purple/green and red) had no interaction among treatments. C. amboinicus Lour. produced one putative mutant and C. blumei purple/green produced four putative mutants based on the morphology.Keywords: Coleus amboinicus Lour., Coleus blumei, LC50, putative mutan

Abstract

The soaring price of fertilizer followed by the scarcity of fertilizer supplies has caused farmers to be unable to buy. The impact of this has caused crop production to decline and has decreased farmers' income. This community service activity aims to provide a solution to reduce fertilizer prices by introducing and practicing how to make solid organic fertilizer (SOF) and liquid organic fertilizer (LOF). The community service activity method uses socialization, practice, application of technology, assistance, and evaluation. The perceptions and expectations before and after the practice of making solid organic fertilizer and liquid organic fertilizer are the same, namely 95% are in the high category. All participants were very enthusiastic about the solid organic fertilizer and liquid organic fertilizer manufacturing technology package, as seen from the high perception of 95%. Participants also have high expectations of 95% for the technology package provided as seen that the participants will practice making SOF and LOF independently.
