Abstract

Environmental awareness is one of the important aspects that need to be instilled from an early age, because children are the next generation who will face ecological challenges in the future. One creative approach that can be used is ecoprint training, which is a technique of printing patterns on fabrics by utilizing natural leaves, flowers, and plants around the environment. This study aims to see how ecoprint training can increase creativity while fostering environmental awareness in children in Solodengeun Village, Panimbang Jaya Village. The method used is qualitative descriptive with stages of activities in the form of preparation, socialization, demonstration, direct practice, and evaluation. Data was collected through observation, documentation, and brief interviews with participants. The results of the activity showed that the children followed each stage with great enthusiasm. They are not only able to produce unique works of art from natural materials, but also understand the important value of taking care of the environment through the wise use of resources. This activity has been proven to foster curiosity, improve motor skills, train creativity, and instill ecological values in a fun way. Overall, ecoprint training has proven to be effective as a holistic learning medium that combines art, creativity, and environmental education. This program not only provides a memorable learning experience, but also forms an eco-friendly character from an early age. Thus, ecoprints deserve to be developed more widely in schools and communities as an alternative strategy in instilling environmental awareness while honing children's creativity. Keywords: ecoprint, children's creativity. Environmental education, ecological awareness

Abstract

Experimental evaluation of the thermalperformance of the split duct type Heating,Ventilation, and Air Conditioning (HVAC) systembased on R-410A refrigerant in a two-story building ina tropical climate. The main focus of the research isdirected at the characteristics of temperaturedistribution, heat transfer capacity, performancecoefficient (Coefficient of Performance - COP), aswell as thermal efficiency of the Carnot cycle. Testingwas carried out for four weeks in real operatingconditions with direct measurements at the diffuserpoints to obtain parameters of temperature, pressure,and compressor power. The experimental results showthat the temperature of the compressor and condenserincreases proportionally to the cooling load, while thetemperature of the evaporator is stable in the range of255-275 K. The COPactual value ranges between 2.8-3.5, with a system efficiency of 50-85% compared toideal conditions. The higher performance on thesecond floor emphasizes the influence of the verticalthermal load on the actual cooling capacity. Overall,the split duct system based on R-410A shows goodoperational stability and energy efficiency, making itsuitable for cooling applications in low-rise buildingsin tropical climates.
