The method of this study was qualitative with descriptive design. Subject of the study was one teacher and 10 students of XI IPA3 of SMAN No.3 Langsa. The data were collected by using questionnaire and documentation. Based on the result of the research, the experience of teaching activity using shift system has an impact on the learning process. The teacher must arrange the schedule and students material according to the syllabus continuously for different days. It often leads the teacher to repeat the material was unintentionally. In addition, the duration of learning is only 30 minutes, which the previous was 45 minutes. Then, students also experienced obstacles during the learning. Students found difficulties in understanding the materials explained by the teacher because the duration was short. The system made them lazy to study as the learning is divided in to shift A & B. It can be concluded that the teaching activity using the shift system do not run optimally.

Abstract

The demand for avocados in Indonesia continues to rise, while the availability of high-quality seedlings remains limited. Propagation through stem cuttings with the application of IBA (Indole Butyric Acid) is expected to improve propagation success. This study aims to determine the effect of IBA concentration on the growth of avocado stem cuttings. The research was conducted in Bojonegoro, East Java, using a Completely Randomized Design (CRD) with one factor, namely five concentrations of IBA: 0, 75, 100, 125, and 150 ppm. Observed parameters included shoot length, number of shoots, number of leaves, and number of primary roots. The results showed that IBA concentration had a significant effect on all observed parameters, while cutting length had no significant effect. A concentration of 100 ppm produced optimal growth of 1.92 cm, 2.50 shoots, and 4.33 leaves. The treatment without IBA resulted in the lowest values. The application of IBA at concentrations of 75–100 ppm effectively enhanced the growth of avocado stem cuttings, particularly in shoot and leaf development.
