This study aims to find out whether there is a difference between students who are treated using blended learning strategies and students who are treated using offline learning strategies. This research was carried out at Pamulang University. The research method used is a quantitative approach with the quasy experimental method. Samples were taken by cluster random sampling. The sample was taken as many as 50 students consisting of 25 students in the experimental class and 25 students in the control class. Instrument tests are validity tests and reliability tests. The validity test uses the product moment formula, and the results are all valid while the reliability test uses the alpha formula and reliable results are obtained. The data collection technique used in this study is in the form of the results of the students' mathematical comprehension ability test. Data analysis using a non-parametric test using the Mann-Whitney Test The results of the data analysis showed that the significance value was 0.015<0.05 so that there was a significant difference between the class that was given the blended learning strategy treatment and the class that was given the offline learning strategy treatment

Jumlah penduduk yang semakin meningkat berdampak pada peningkatan jumlah limbah kulit buah-buahan. Tidak hanya daging buah yang kaya akan nutrisi, namun kulit buah-buahan juga mengandung berbagai senyawa bioaktif yang dapat diaplikasikan dalam bidang pangan, farmasi, dan lain-lain. Tanin yang termasuk ke dalam golongan polifenol juga ditemukan pada berbagai jenis tanaman. Penelitian ini bertujuan untuk menentukan kadar tanin pada ekstrak etanol kulit buah naga dan kulit buah semangka. Ekstraksi kulit buah dilakukan dengan metode maserasi menggunakan pelarut etanol. Pengujian secara kualitatif dilakukan dengan skrining fitokimia dan penentuan kadar tanin ditentukan dengan metode Spektrofotometri UV-Vis. Hasil skrining fitokimia adalah kedua ekstrak mengandung tanin dan saponin. Sementara itu, kadar tanin pada ekstrak etanol kulit buah naga (BN) dan kulit buah semangka (SMK) berturut-turut adalah 0,3817±0,0000 μg TAE/g dan 0,2681±0,0004 μg TAE/g.

This study aims to describe the mathematical understanding ability of students regarding the concept of definite integral based on APOS Theory, and describe the achievement of each indikator of students' mathematical understanding ability regarding the concept of definite integral of algebraic functions based on APOS Theory. The research method used is descriptive qualitative. The data collection techniques used in this study were written tests and interviews. The results showed that the achievement in question number one on the K indikator 88.89%, L 83.33% and S 69.44%, most of the students who were able to solve the problem meant that they had been able to organise the actions, processes, and objects they had so that based on APOS theory, the student was at the level of understanding the scheme. Achievement in question number two on indikator K 80.55%, L 58.33% and S 50%. Most students are only able to identify properties and conditions, meaning that students only have the ability to understand at the action stage. Achievement in question number two on indikator K 86.11%, L 66.67% and S 63.88%. Most students are only able to identify properties and conditions and work on problems according to the steps.

Statistics is an essential course in the curriculum of the Informatics Engineering Study Program, as it plays a crucial role in equipping students with skills in data analysis, information processing, and data-driven decision-making. However, various studies have reported that students often experience low self-efficacy in statistics, which can hinder their academic performance and engagement. This study aims to compare the effectiveness of the ICT-based APOS model and the M-APOS model on students’ self-efficacy, taking into account their Initial Mathematical Ability (IMA). The APOS theory provides the foundation for the instructional models used, while Bandura’s theory of self-efficacy underpins the construct being measured. A quasi-experimental method was employed using a 2 × 2 factorial design (treatment by level). The data analyzed were students’ scores on a validated and reliable self-efficacy questionnaire, and a two-way ANOVA was used as the analytical technique. Prerequisite tests included the Lilliefors test for normality and Levene’s test for homogeneity. The rationale for selecting the ICT-based APOS and M-APOS models lies in their potential to address cognitive and metacognitive learning challenges in mathematical thinking. The results showed that, overall, students taught using the ICT-based APOS model demonstrated higher self-efficacy than those taught with the M-APOS model. A significant interaction was found between the learning model and IMA on students’ self-efficacy. Students with high IMA who received instruction through the ICT-based APOS model exhibited greater self-efficacy than those who experienced the M-APOS model. Among students with low IMA, there was no significant difference. These findings suggest that integrating technology into constructivist learning models such as APOS can enhance students’ confidence in learning statistics, particularly for those with a strong mathematical foundation, and inform future innovations in adaptive, ability-sensitive instructional design.
