The ability of mathematical comprehension and counting skills of students is an important aspect that needs understood by students in mathematics learning in elementary school. The aim of this research is to find out the improvement of mathematical comprehension ability and counting skills of students who get learning with contextual approaches, studying contextual approaches, and studying conventional approaches to the study of physiology. This research method is quasi experiment with data collection technique using pretest and posttest. The samples of this study were the second grade of SDN 1 Tangkil, SDN 3 Kedongdong, and SDN 1 Wiyong, and then based on the results of the different test of the sample were bound and identified that the three classes could improve the ability of mathematical comprehension and counting skills. Based on the average test of the average free sample using H-test (Kruskal-Wallis), it is known that there is a difference in the average ability of mathematical comprehension and counting skills in the three experimental classes, and it can also be known the relationship between mathematical comprehension ability and student counting skills.

Although studies on online learning have been widely discussed, most of the studies still focus on the students’ experiences adjusting to online learning. However, few studies have analyzed students’ experiences in online learning regarding autonomous learning implementation. This study aimed at identifying Indonesian EFL students' autonomous learning implementation in online learning. A questionnaire adapted from Khotimah et al. (2019) and Hidayati and Husna (2020) was used as a single instrument to obtain data from EFL students from 22 universities around Indonesia. This study sample was selected using a random sampling technique, and the data was analyzed using a simple percentage statistics formula. The results showed how students learned English online in four areas: listening, reading, speaking, and writing. They also showed how the students felt about online learning on their own. These experiences relate to students’ experiences selecting learning materials and learning activity preferences. These preferences are divided into learning English for academic purposes and learning English for pleasure. However, regarding students’ efforts to foster their autonomous online learning, the students had implemented three categories of autonomous learning, namely the initiating process, monitoring process, and evaluating process in their learning process. Hence, the research results are expected to provide new insights for the readers about implementing online learning, which can support the students to be more autonomous learners.

A protein can be identified based on each level of its structure. Every protein contains at least primary, secondary and tertiary structures. Only a few proteins have a quaternary structure as well. The primary structure consists of a linear chain of amino acids. One of the electric field-mediated separation methods that is often applied to analyze proteins based on their size is SDS-PAGE electrophoresis. This technique is based on the assumption that after denaturation, the polypeptide chains covered in SDS micelles have comparable surface charge densities, so that the resulting differences in electrical migration are based on their size. SDS-PAGE separates protein molecules based on their particle size and shape. This gel can be made with varying pore sizes which are determined based on the total amount of acrylamide compound added (gel concentration). The gel pore size will become smaller as the gel concentration increases so that only protein molecules that have a small molecular weight can pass through. This measure of the molecular weight of a protein is useful in mapping proteins (protein profiling). The gel staining used is bromophenol blue which functions to color proteins because it binds weakly to proteins. The higher the protein concentration of a sample being electrophoresed, the resulting band will appear clear and thick. However, if the protein concentration of a protein is low, the resulting band will appear thin.

Abstract: The increase in maternal and child mortality is still one of the serious problems in the world of health, especially in developing countries such as Indonesia. Based on the initial survey, it is known that Kassi-Kassi Health Center is one of the health centers with the highest pregnancy rate but has not reached the target regarding ANC visits in Makassar City. The purpose of the study was to determine the relationship of several factors that influence pregnant women's compliance with antenatal care visits at health facilities. The research design used in this study was cross sectional. The research was conducted at Kassi-Kassi Health Center in November 2024. The population of pregnant women in trimester 3 who made antenatal care visits at the Kassi-Kassi Health Center in Makassar City in September 2024, totaling 115 pregnant women. The sample amounted to 50 respondents. The sampling technique used in this study was purposive sampling. Data analysis was performed univariate and bivariate. The results showed a relationship between the parity of pregnant women (p value: 0.00) and the work of pregnant women (p value: 0.002) on antenatal care visits. It is recommended to the health center to be able to hold counseling evenly in 6 villages at the Kassi-Kassi Health Center regarding the importance of conducting antenatal care checks for the health of mothers and children.Keywords: Antenatal Care, Toddler, Parity.

Abstract. The global halal industry is growing not only in the food and beverage sector, but also in digital media through blogs and podcasts on the theme of halal lifestyles. These platforms serve as a means of education and da'wah while also opening up monetization opportunities in the digital creative economy. This study analyzes monetization strategies and their relationship to financial sustainability through a qualitative literature review of journals, industry reports, and international publications. The results of the study show that financial sustainability can be achieved through diversification of advertising models, sponsorship, affiliation, subscription, merchandise, and crowdfunding tailored to the audience. Integration with halal cuisine, fashion, tourism, and sharia financial support further strengthens sustainability. Abstrak.

Knowing the teaching strategy is very important in the teaching and learning process because it dramatically influences the students' outcomes. Many studies on teaching strategies have been done in many parts of the world. However, the studies on teaching strategies in the pandemic era applied by the teachers in a reputable school in Indonesia are rarely discussed. Thus, this research aims to explore a reputable school's teachers' experiences in applying strategies during covid-19. There were three senior high school teachers from one of the reputable schools in Bengkulu who participated in this research. This research adapted a case study design by using a semi-structured interview as the research instrument. The interview data were recorded, transcribed, and coded into several themes based on the focus of this research. The result showed that the teachers tended to use the same materials, such as books from the government and materials from the internet. In addition, the teachers dominantly use zoom meetings for the teaching media. Meanwhile, they had their preferences on the teaching strategies. Generally, the teachers prefer to implement online discussion, computer-based learning exercises, online collaboration projects, online lectures, independent study, and online learning using social networking as the teaching strategies. The result of this study can be used as a guideline for teachers from other schools in implementing the teaching strategies, especially in online teaching.
