Abstract

The Teaching Campus aims to improve the quality of education in Indonesia where one of the work programs carried out is to increase literacy which is important knowledge to be mastered by elementary school students in order to succeed in education and daily life. This study aimsto analyze efforts to improve the literacy of SMP N 15 Bengkulu Tengah students through an effective approach, this study was conducted by involving grade 7 and 8 students of SMP N 15 Bengkulu Tengah whose literacy level is still low. The method used is qualitative descriptive with the object of using interesting reading books, project-based teaching, and the use of technology in learning. The results showed that an approach involving interesting reading books was able to increase students' reading interest. In addition, creativity-based teaching allows students to develop critical and problem-solving skills, while the use of technology provides wider access to learning resources, this research makes an important contribution to improving the literacy of SMP N 15 students. The results suggest that diverse and innovative approaches can increase students' interest in reading and their overall literacy skills.

Abstract

This study evaluates the effect of liquid natural rubber latex and cement filler on the Marshall characteristics of Asphalt Concrete–Binder Course (AC-BC). A laboratory experiment was conducted using two asphalt contents (4.5% and 5.5%) and four latex contents (0%, 8%, 10%, and 12% by asphalt weight). Three specimens were prepared for each combination, resulting in 24 Marshall specimens. The evaluated parameters were voids in mixture (VIM), voids in mineral aggregate (VMA), voids filled with bitumen (VFB), stability, flow, and Marshall Quotient (MQ). At 4.5% asphalt, the 12% latex mixture produced the highest stability of 1,036.8 kg and an MQ of 343.44 kg/mm. At 5.5% asphalt, the 8% latex mixture produced the highest stability of 1,085.0 kg and an MQ of 371.46 kg/mm. All modified mixtures satisfied the minimum stability requirement and the specified flow range. The control mixture at 5.5% asphalt had a VIM of 2.87%, below the 3–5% requirement, whereas latex-modified mixtures remained within the range. The response was non-linear, indicating an optimum balance between asphalt, latex, and cement filler. Latex addition can improve load-bearing capacity and mixture stiffness when applied at an appropriate dosage.

Abstract

This study aims to determine the effect of the Problem Based Learning instructional model on students’ learning outcomes in the topic of living things classification in Grade VII junior high school. This research is a quasi-experimental study with a pretest-posttest control group design, conducted in the even semester of the 2025/2026 academic year at SMP Negeri 3 Medan. The population in this study consisted of all Grade VII students, comprising eleven classes. The sample was selected using cluster random sampling technique, with class VII-I assigned as the experimental group, which was taught using the Problem Based Learning model, and class VII-H assigned as the control group, which was taught using the Direct Instruction model. The data collection instrument was a validated multiple-choice test consisting of 20 questions measuring learning outcomes. Data were obtained through pre-test and post-test and analyzed using a one-tailed t-test. The results showed that the mean pre-test and post-test scores in the experimental class were 40.94 and 79.69, respectively. Meanwhile, the control class obtained mean pre-test and post-test scores of 41.56 and 75.16, respectively. The hypothesis testing results showed that tcount > ttable (1.92 > 1.670), so H0 was rejected and Ha was accepted. Thus, it can be concluded that there is a significant effect of the implementation of the Problem Based Learning model on students’ learning outcomes in the topic of living things classification for Grade VII students at SMP Negeri 3 Medan.
