Abstract

Students who have good communication skills tend to find it easier to understand the material, collaborate with classmates, and complete assignments. Communication skills must be established in students. Learning is not optimal without good communication (good interaction between educators and students). The research on applying the multi-representational discourse (MRD) learning model. This study aimed to explore how this model can improve students' communication skills. The method used in this study was classroom action research. This study was conducted on grade XI students at MAN Kota Palangka Raya with 36 respondents. The data analysis technique used is a quantitative analysis technique to compare student activities during the cycle. The results showed an increase in students' communication skills using MRD learning. The MRD model encourages students to discuss and exchange opinions actively, improving their ability to communicate verbally and non-verbally. The results showed increased students' communication skills, especially in expressing opinions, discussing, making presentations, and asking questions. The use of models that involve active interaction between students, such as group discussions, can have a positive impact on the learning process.

Abstract

Hydroponic techniques are one of the intensification efforts that will ultimately increase the use of land and nutrient solutions. Nutrient solutions use liquid organic fertilizers (POC), which contain the composition of nutrients needed by plants such as AB Mix fertilizer, but are sold at very cheap prices because they are made from fermented organic materials. The organic waste needed in making fertilizer, researchers use red onion skins, banana stems, and kiambang as liquid organic fertilizer because this waste is often found but has not been utilized optimally. The method in this research used a Completely Randomized Design (CRD) which was analyzed using Analysis of Variance, there were 5 treatments P0 (AB Mix 100% Control), P1 (POC 25% + AB Mix 75%), P2 (POC 50% + AB Mix 50%), P3 (POC 75% + AB Mix 25%), P4 (POC 100%). The purpose of this study was to determine the effect of a combination of liquid organic fertilizers of red onion skin, banana stem kepok and kiambang as liquid organic fertilizers for hydroponic lettuce. After conducting experiments and calculations using ANOVA, the results of the effect of the combination obtained the best combination of nutrients in treatment 1, namely 75% AB Mix and 25% POC, with the parameters of leaf width, plant height and the maximum number of leaves
