Abstract

This study aims to determine students' science process skills through practicum method on cell material for class XI IPA of SMA Negeri 1 Tapa. The research method used quasi-experimental, a posttest-only non-equivalent control group design. Data collection was performed through observation sheets and test questions. The data analysis used is the t-test. According to research conducted in class XI IPA 1 using the practicum method, students in the experimental class had an average science process skill score of 79%. In contrast, students in the control class, which did not use the practicum method, had an average of 55%. Therefore, the science process skills of students in the experimental class are higher than those in the control class due to the use of the practicum method. Teachers guide students in activities during the learning process by asking open-ended questions that spark a discussion. Students are therefore required to be active, creative, and able to collaborate during the learning process to meet the learning objectives and understand the concepts being taught easily.

Abstract

This study aims to determine the effect, effective concentration, Lethal Concentration 50 (LC50), and Lethal Time (LT50) of tembelekan leaf extract (Lantana camara L.) on the mortality of Riptortus linearis and metabolic compounds of L. camara leaves. The method was experimental. The study used a completely randomized design (CRD) with five treatments, namely 0%, 10%, 15%, 20%, and 25%, and five replications. Each treatment contained 10 R. linearis test animals. The results of the ANOVA analysis showed the effect of treatment on the mortality of R. linearis (p<0.05). The concentration that showed the highest mortality was 25%. Based on the LC50 test, the 10.155% L. camara leaf extract concentration can kill R. linearis in more than 50% of each treatment. And based on LT50 with a concentration of 25%, it takes 7.681 hours to kill 50% of R. linearis. In L. camara leaf extract contains metabolite compounds, namely alkaloids with a level of 307.87 mg/L, then tannins with a group of 2.75 %b/v, then saponins with a group of 0.31 %b/v, and flavonoids with a group of 1.40 %b/v., It can be concluded that there is an influence of giving tembelekan (Lantana camara L) leaf juice on the mortality of Riptortus linearis.
