Abstract

Learning objectives are defined as statements that specify the goals to be achieved in the learning process. The learning objectives of biology in schools are mainly centered on improving students' ability to think critically, creatively, and analytically as well as increasing their understanding of the benefits of biology in everyday life. This research takes a qualitative approach by using the literature study method as its main foundation. The main focus of the research is to explore an in-depth understanding of the relationship between learning objectives and their achievement for biology learning in high school. The data analysis process is carried out systematically to classify information, identify, and synthesize the findings obtained from the literature studied.The purpose of learning design is to improve the quality and effectiveness of the teaching and learning process. This can be achieved by selecting, determining and developing the most appropriate and optimal learning methods based on the needs and characteristics of students, the learning objectives to be achieved and the resources available. A good learning design will ensure that the learning process runs smoothly and achieves the desired results. Clear learning objectives have a significant influence on the achievement of biology learning in high school students. The formulation of clear biology learning objectives and teachers' efforts to realize them are important factors in improving the quality and achievement of biology learning in high school students.

Abstract

Cigarette packaging contains cellulose acetate, which is difficult to decompose and pollutes the environment. This study aims to utilize this waste as an alternative growing medium in hydroponic systems. The experimental method was applied to water spinach (Ipomoea aquatica) plants by comparing its performance with Rockwool. The implementation stages included physical cleaning, sterilization with 70% alcohol, and boiling to remove harmful chemical residues. Based on observations over 26 days, the Independent Sample T-test results showed a significant value of 0.86 (p > 0.05). This indicates that there was no significant difference in plant height and number of leaves. The implication is that cigarette butt waste has been proven to be effective as a growing medium equivalent to Rockwool.
