Abstract

Avocado (Persea Americana, Mill) has been used traditionally to cure disease but the effect has not proven scientificaly. This study reports the determination of anti inflammation effect of ethyl acetate fraction and hexane fraction of avocado leaves at various dose : 100, 200 and 400 mg/KgBW respectively. Inflammation was induced by using Paw edema method with induction of 1% carrageen 0,5 ml. Phenylbutazone at dose 9 mg/KgBW was used as positive control, while 1% sodium CMC given 1 hr before induction was used as negative control. The edema volume was determined at one hour interval for 5 hours, and percentage of inhibition was then calculated. Result indicated that the ethyl acetate and the hexane fractions of avocado leaves at doses 100, 200, and 400 mg/KgBW showed significant anti-inflammation effect (p<0.05). The best effect was given by the ethyl acetate fraction at dose 400 mg/KgBW.

Abstract

Abstract Based on the learning outcomes of students of class XI.IPA.4 SMAN 1 Kinali in Biology sub Subject Describes the structure and function of certain human and animal organs, abnormalities or diseases that may occur and the implications found that the students' learning outcomes in the subjects Biology sub Describes the structure and function certain human organs, possible abnormalities or diseases and their implications are still very low. The average student learning outcomes are still under the KKM. The purpose of this study is to describe and obtain information about efforts to improve student learning outcomes in the subjects Biology sub Describes the structure and function of certain human and animal organs, abnormalities or diseases that may occur as well as the implications through the model of Various Card Quiz Learning in class XI.IPA. 4 SMAN 1 Kinali West Pasaman District. This research is a classroom action research. The research procedures in this research include planning, action, observation and reflection. This study consists of two cycles with four meetings. The subjects consisted of 33 students of class XI.IPA.4 SMAN 1 Kinali. The data were collected using observation sheet and daily test. Data were analyzed using percentages. Based on the results of research and discussion that have been put forward, it can be concluded that the learning model Card Quiz Bervariasi can improve student learning outcomes in the subjects Biology Sub Writing Text Speech / lecture / sermons with systematic and effective language in SMAN 1 Kinali. Student learning outcomes from cycle I to cycle II. Student learning outcomes in cycle I was 53.52 (Less) increased to 83.24 (good) with an increase of 29.72.Keywords: Learning Outcomes, Biology, Varied Card Quiz learning model

Abstract

Bean robusta coffee contains polyphenol compounds which are useful as antioxidants. Antioxidants can inactivate the development of oxidation reactions, by preventing the formation of free radicals. Robusta coffee bean plant (Coffea canephora) is an ingredient that can be formulated into lotion preparations. Cosmetic lotion aims to remove dead skin cells, brighten the skin and soften the skin. This research is to make lotion preparations from robusta coffee bean extract (Coffea Canephora) . This research uses pure experiment. Robusta coffee beans are extracted by maceration process. The lotion formulation is made with variations of robusta coffee bean powder (Coffea Canephora) with a concentration of 2%, 3%, and 4%. The characteristic test includes organoleptic test, homogeneity test, Ph test, and irritation test. The purpose of this study was to determine the lotion formulation for robusta coffee bean extract (Coffea Canephora). The results of the lotion test had a homogeneous concentration of 2%, 3% and 4%, light brown to blackish brown, with a distinctive smell of coffee. The ph lotion test had a PH of 5 in all formulations on the blank had a PH of 6. The irritation test on the lotion preparation showed no erythema and edema in 5 volunteers. From all the tests carried out, the lotion formulation has good characteristics.

Abstract

Writing scientific papers is a critical academic skill that students must develop to express ideas derived from observation, research, or analysis in a structured and methodical manner. However, students often face challenges in mastering this skill. This study investigates the effectiveness of the Problem-Based Learning (PBL) model in improving students’ ability to write scientific papers. The research employed Classroom Action Research (CAR), implemented in two cycles at MA Mizanul Ulum YW UMI Sanrobone. Each cycle followed the stages of planning, implementation, observation, and reflection. The study involved student participants who were observed through activity sheets and assessed through writing assignments. Data were analyzed using both qualitative and quantitative descriptive techniques. Findings indicate a notable improvement in students' scientific writing performance after the implementation of the PBL model. In Cycle I, the average student score was 64, indicating that most had not yet met the minimum competency standard. After refining the instructional approach in Cycle II, the average score increased significantly to 81, demonstrating that all students achieved the required level of competence. The results suggest that the PBL model fosters student engagement and enhances their ability to develop and organize scientific content effectively. By actively involving students in problem-solving tasks, the model promotes deeper understanding and better writing outcomes. Implementing the PBL approach significantly improved students’ scientific writing skills and learning outcomes. This model is recommended for broader application in similar educational settings.
