The concept that refers to a person's ability to organize, supervise, and control learning strategies for effective learning is called self-regulated learning. Many studies related to self-regulated learning have received significant attention because of its potential to affect student academic achievement, but not many studies have focused on self-regulated learning at the academic level. This study aims to determine the differences in self-regulated learning of mathematics education students at Prof DR HAMKA Muhammadiyah University based on academic level. The research sample consisted of 71 students from various academic levels. Self-regulated learning was measured using a questionnaire with indicators of personal function, behavior function, and environment function. The research findings obtained are that there are no differences in self-regulated learning of mathematics education students based on academic level.  Based on these findings, it shows that academic level does not influence self-regulated learning in mathematics education students. Keywords: Self-regulated learning, Academic Level, Mathematics Education Students

Abstract

Social connection requires each individual to have a strong understanding of the environment. Concept understanding can be improved through software. The goal of this research is to predict the effect of mathematics learning using Cabri 3D software. The dependent variable is the mathematics concept of understanding ability. The independent variable is the dummy variable that determines the type of the class. The value of the dummy variable for the class that applied the Problem-based Learning (PBL) assisted by Cabri 3D is 1 and the value of the dummy variable for class without Cabri 3D is 0.  Students' mathematics ability was measured by a percentage or probability. The values of the mathematical concept understanding obtained by students were converted into probability values. After the data has been collected, probit regression analysis was used to see the probability of success of mathematical concepts understanding of those who were taught using PBL and those who were taught without using PBL without Cabri 3D. The results of data analysis showed that the types of classes significantly affect the mathematical concept of understanding ability. Thus, it can be concluded that learning with Cabri 3D can improve the mathematical concept of understanding ability.

Abstract

The study aimed to predict the chances of success from the use of the Problem-based Learning (PBL) model compared to the Teams Games Tournament (TGT) toward students’ learning outcomes. The research was conducted to the eleventh-grade students of Senior High School 106 Jakarta on the limit of algebraic function material. The data were collected through a posttest of 5 description questions. After the data had been collected, it was analyzed using probit regression which can provide more information than using just the means of two populations. The independent variable was the class and the dependent variable was the learning outcome. The class independent variable was a dummy variable with the value of "1" which applied the PBL model and the value of "0" was the class that applied the TGT cooperative learning model. The resulting probit regression model was the alleged Probit (mathematics learning outcomes) = 1,114 - 0,483 (class). Based on the probit regression model at the 5% significance level, it can be concluded that the alleged students who were taught using the TGT cooperative learning model had a 13% greater chance of success/correct in working out the questions compared to students who were taught using the PBL. The results showed that the TGT cooperative learning model can improve students’ learning outcomes better.

Abstract

This study aims to analyze the potential of biogas production from a mixture of cow dung and water hyacinth (Eichhornia crassipes) as an alternative energy solution in East Kutai. The research applied an experimental method with four substrate composition treatments: P1 (85% cow dung : 15% water hyacinth), P2 (75%:25%), P3 (60%:40%), and P4 (100% cow dung). Each treatment was fermented for 20 days using laboratory-scale biodigesters, with daily monitoring of gas pressure and internal temperature. The results showed that P4 generated the highest biogas pressure (2.9 kPa), while increasing the proportion of water hyacinth reduced production efficiency. Fermentation temperatures remained stable within the mesophilic range (35–38°C), indicating ideal conditions for methanogenic microbes. MANOVA analysis confirmed that substrate composition significantly affected both pressure and temperature (p < 0.05). This study demonstrates that co-digestion of livestock and aquatic biomass waste can be an effective strategy for renewable energy production and organic waste management. The findings are applicable for the development of local-scale biogas technology in biomass-rich areas.

Abstract

This study aims to see whether there is an influence of AQ and SE, both partially and simultaneously on the ability to understand mathematical concepts in vocational students. The research method used is quantitative research with a population of all grade XI students, and a sample of 95 students. Data were collected through questionnaires to measure AQ and SE variables, as well as five essay questions on statistics material to measure the ability to understand mathematical concepts. The analysis results showed that the significance values of AQ and SE were 0.041(<0.05) and 0.858(>0.05). This means that partially only AQ has an influence on students' mathematical concept understanding ability. However, the results of the F test showed a significance value of 0.029(<0.05), so that simultaneously AQ and SE affect the ability, with a contribution of 5.4%.

Abstract

This study aims to analyze how conditions during the Covid pandemic and new strategic steps affect sustainability. We use the inferential verification technique, which is a strategy used by researchers to assess the validity of the presented hypothesis by collecting actual data from alumni, lecturers, students, partners, parents, leaders and education staff of Universitas Muhammadiyah Prof. DR. HAMKA Jakarta. A total of 222 research samples were deliberately selected as respondents. We used Structural Equation Modeling (SEM) analysis, assisted by Smart PLS software version 3.2. for quantitative analysis to test the hypothesis and for qualitative analysis obtained based on the results of interviews with several parties related to the UHAMKA Jakarta as a material for discussion in the research. Several findings were found: (1) the Covid pandemic condition had a significant positive effect on the new strategy; (2) the new strategy has a significant positive effect on sustainability; and (4) the new strategy has a mediating function in the influence of the Covid-19 pandemic condition on the sustainability of the University of Muhammadiyah Prof. DR. HAMKA Jakarta. The limitation of this research is that the survey only focuses on the University of Muhammadiyah Prof. DR. HAMKA Jakarta only. Practical implications: According to research findings, new strategies are needed to increase sustainability in urgent situations, for example during the Covid-19 pandemic. By implementing and implementing the new strategy, the sustainability of the university as an educational institution will be better maintained. The new strategy variable proved to be a mediating or intervening variable for the Covid-19 pandemic condition in influencing the sustainability of the University of Muhammadiyah Prof. DR. HAMKA Jakarta. University of Muhammadiyah Prof. DR. HAMKA Jakarta must be able to adapt to a new life after a pandemic through a crisis period so that it can maintain its sustainability in the future.
