Abstract

The skills that can be developed through education are 21st century skills, including the ability to solve problems related to issues faced in everyday life. Therefore, students need to be taught problem solving by using PBL model based on multiple representations on ecosystem material. The purpose of this study was to analyze the effect of PBL based on multiple representations in class X ecosystem material on students' problem solving skills. The research design used is an experiment with the quasi experiment method. The population in this study were all grade X students at SMAN 14 Semarang in the 2023/2024 school year. Sampling in this study using purposive random sampling technique based on the teacher's consideration that the selected class has a balanced ability. Two classes were sampled, namely class X5 as the experimental class which was given treatment using PBL model based on multiple representations and X9 as the control class which was given treatment using PBL model without multiple representations. Based on the results of the research, students' problem solving skills have increased in both experimental and control classes. The N-Gain test results of the experimental class are 0.3661 which means an increase in problem solving ability is moderate, while the N-Gain results of the control class are 0.1544 which means an increase in problem solving ability is low. The T-test results show that there is a significant difference between the average pretest-posttest scores in the experimental class and a significant average difference between the posttest scores in the experimental and control classes. The results of the Spearman Rank correlation test show that the Sig. (2-tailed) 0.880>0.05 which means that the application of PBL based on multiple representations has no effect on students' problem solving skills on ecosystem material. This can be influenced by several factors, namely the PBL model used, the formation of discussion groups, and also the number of multiple representations taught to students.

Abstract

Rambutan (Nephelium lappaceum L.) is one of the many tropical plants found in Indonesia. The leaves of the rambutan plant are known to be used as medicine, so they have the potential to be a source of endophytic bacteria that can produce beneficial compound. This study aims to isolate, identify of endophytic bacteria from rambutan leaves, and test their activity as an antibacterial with two different secondary metabolite extraction methods, namely maceration with 70% methanol and without maceration. This study used experimental research with a Completely Ramdomized Design (CRD). Isolation of endophytic bacteria from rambutan leaves produced two isolates (D1 and D2). The results of identification through macroscopic, microscopic, and biochemical test showed that two pure isolates had similarities to genus Bacillus sp. Antibacterial activity testing was carried out using well diffusion method. Based on the results of antibacterial test showed that extraction method with 70% methanol produced an extract that was more effective as an antibacterial with average diameter of clear zone formed for Escherichia coli bacteria were 13.55 mm (Isolate D1) and 12.13 mm (Isolate D2) and that of Bacillus subtilis bacteria were 16.27 mm (Isolate D1) and 19.69 mm (Isolate D2). This finding contributes to the fact that the type of secondary metabolite extraction method of rambutan leaf endophytic bacteria influences the sensivity as an antibacterial.

Abstract

Mangunsari Village is one of the goat farming centers in Gunungpati District, Semarang. They raise goats from generation to generation and based on experience, so care patterns are often not uniform from one to another. In addition to feed, animal hygiene and health are very important to implement in enforcing biosecurity in the pen and its surrounding environment. The goal of this activity is to improve goat health and the safety of the pen environment through biosecurity. The community service is divided into two: providing materials and training followed by practice. Twenty participants, members of the Mekar Sari 2 livestock farmer group, were accompanied by a team of nine lecturers, technicians, and students. The activity began with filling out a questionnaire, theory, and ended with practice. Data obtained showed that 53.8% were aged > 50 years and 23.1% were < 40 years. In addition, 84.6% of participants had been members of the livestock farmer group for a long time (≥ 10 years). There was a 0.2% increase in knowledge regarding infectious diseases, a 2% increase in leaf and grass feed, a 61.6% increase in forage that must be wilted, and a 7.7% increase in pen cleanliness. Participants also understood that forage is best not provided wet (40.5%). The results concluded that this activity improved knowledge about biosecurity components and the participants' skills in physical examination of goats and pen cleanliness.
