Abstract

Indonesian Aviation Polytechnic of Curug (PPI Curug) uses power from PLN of 3 Mega Watts. Since the beginning implementation of the electrical system at the PPI Curug Campus, adjustments have never been made. The additions of a new distribution system did not go through careful planning, this can be shown by the data that until now there are still buildings at PPI Curug which are supplied with a voltage of 110 V per phase. Upgrading the electrical system in several buildings that are supplied with a voltage of 110 V per phase has been carried out slowly through the adjustment mechanism of the electrical installation in these buildings, and has not yet touched on the distribution system. The large number of power transformers turned out to be not proportional to the power supply borne by each transformer, and overall none of the transformers was burdened more than 40% of the nominal load. On the other hand, the number of electricity subscription bills paid by PPI Curug has increased from year to year. This study aims to determine whether the electricity distribution system used at PPI Curug is currently effective and efficient and to determine an effective and efficient electricity distribution system based on the characteristics of the area and type of load at PPI Curug. The research method used is an evaluative qualitative method which will describe the condition of the distribution system and installation at PPI Curug, then evaluate it based on existing standards. The differences that exist between the real conditions in the field and the existing standards will be used as conclusions and suggestions for improvements. The results showed that the percentage value of the efficiency of all transformers showed a value of 95% so that the efficiency of the transformer at PPI Curug was categorized as good, but the condition that there was still a large amount of unused power needed to anticipate the use of electrical power beyond the requirement.

Abstract

This paper will discuss the view of mathematics education as science. This study is the result of a variety of relevant literature related to mathematics education as a science in a scientific discipline. Philosophically, mathematics is considered as the queen of science used by humans in everyday life. While knowledge itself is closely related to philosophy, where these two terms cannot be separated from each other. The science of studying natural phenomena itself. Science is the product of epistemology, ontology, and axiology. Philosophy and science are two similarities in that both seek the truth. A person who seeks the truth is a philosopher or philosopher. The source of philosophy is man, reason, and the human heart. For example, mathematics. Mathematics is a science about reasoning, about patterns and mathematics is the queen of science and at the same time a servant of science. Mathematics education is a mathematics lesson that makes students build logical thinking and build mathematical knowledge.

Abstract

This study explored how mathematics teachers improve students' thinking skills from low to higher order thinking skills (HOTS) during class. This study used a qualitative descriptive research design. The research subjects involved were mathematics teachers from one of the high schools in Malang City, East Java, Indonesia. Data were collected through a process of initial observation in schools, the results of preparing lesson plans, classroom assessments by teachers, and semi-structured interviews. The results of the research were analyzed using models, namely data reduction, data presentation, and concluding. Data focused on lesson plans based on a scientific approach and HOTS-based assessments: analyzing, evaluating, and creating. The teachers' class assessments were analyzed and classified into the HOTS cognitive level using the Anderson Krathwohls' Taxonomy indicators. The findings of this study indicate that teachers arranged the class with a scientific approach setting and provided HOTS-based class assessments to students to improve students thinking skills. But on the other hand, teachers experienced obstacles, that are students who are still passive when the scientific method was applied and the learning took a lot of time. Another obstacle related to the HOTS-based assessment is that teachers had difficulty when compiling HOTS-based assessment because it required a lot of time and thinking skill. Students also had difficulty in solving HOTS-based questions due to low reading interest and diverse student abilities.

Abstract

Islamic-based educational institutions needed to internalize Qur’an and hadith in every lesson. Fractions were one of the main subjects of mathematics taught at the elementary school level. The purpose of the study was to design mathematics learning to fractions based on Qur’an and hadith at Madrasah Ibtidaiyah. This study used a qualitative research method with a design research approach of development research type. The results of the study revealed that a learning design could be implemented with a scientific learning approach in fractions learning based on Qur’an and hadith. The verses of the Qur’an and hadith that explicitly mentioned fractional numbers were displayed at the observing stage. Each fractional number in the Qur’an and hadith was illustrated with a length model. Based on the fractional numbers mentioned in the observing stage, students were then directed to submit nutmeg questions in the questioning stage. The questions at the questioning stage were appropriate to the material, then discussed at the reasoning stage while still applying student-centered learning.

Abstract

In Indonesia, the coronavirus disease (COVID-19) decreased from April to May 2022 and in-creased slowly from May to June 2022. Statistical predictions are needed to monitor the increase in cases of this pandemic spike, as happened at the end of February 2022. This study aims to predict the rise in the number of active COVID-19 cases by applying the autoregressive integrated moving average (ARIMA) mathematical model. and multiple linear regression (MLR). Daily observation data of active cases, new cases, recovered cases, and deaths were recorded from January to June 2022 totalling 152 observations. Then ARIMA modelling for active cases and MLR modelling for daily active case observation data that depended on new cases were carried out , recovered, and died. Furthermore, the prediction results from the two models were determined the root mean squared error (RMSE), the mean absolute error (MAE), and the mean absolute percent error (MAPE). From the calculation results, the ARIMA model is smaller than the MLR. However, the prediction of the next thirty days in the MLR model is close to the actual value, while in the ARI-MA model it is below the actual value.

Abstract

Today, everyone places a high importance on their education. Learning is how education is implemented, and learning allows people to reach their full potential. Since learning is a process and learning achievement is the end consequence of the learning process, learning and learning achievement are inextricably linked. Learning achievement levels are assessed using GPA (Grade Point Average). Allowance, gender, major, status of residence, school location, study time, admission type, duration of gadget use, and personality type are all factors that affect GPA. In order to identify the components that influence academic accomplishment, a model must be developed since it can be understood, explained, controlled, and forecasted. This study's goal is to identify the binary logistic regression model, which describes the variables influencing the faculty of mathematics and natural sciences at Universitas Negeri Padang's GPA. The aim of this study is to identify the logistic regression model that represents the variables that affect the GPA of the Faculty of Mathematics and Natural Sciences at Universitas Negeri Padang. Secondary and primary data were employed in this study, and questionnaires were used to collect the data. The 2020 students made up the study's sample, which included 293 respondents. According to the study's findings, factors such as gender, major, admission type, and duration of gadgets use may have an impact on students' GPAs at the Faculty of Mathematics and Natural Sciences at Universitas Negeri Padang. The percentage of correct predictions between the logistic regression model and training data is 70%.

Abstract

The purpose of this study was to find out student errors in solving problems about mathematical literacy. This study uses a qualitative research approach with sampling method is purposive sampling. The study subjects were three students who were taken based on KAM (Student Initial Ability), namely high, medium, and low ability categories. Each subject is one person per category from the Department of Accounting, Bandung State Polytechnic. This study analyzes student errors in solving mathematical literacy problems in the statistics course for the sub-discussion of hypothesis testing. The error analysis method used is Newman analysis. This study uses two instruments, namely a test instrument with four questions in the form of descriptions and interviews. The data will then be classified into five error categories according to Newman's analysis. The conclusions in this study indicate that there are errors in answering questions, especially for mathematical literacy questions; students are expected to be able to analyze questions in the form of story questions; Understanding the problem instructions and information contained in the problem is the first step in working on mathematical literacy problems so that the level of errors and errors in working on the questions is more resolved. Of the five errors that became the standard for Newman Error Analysis assessment, three errors were made by respondents, namely errors in understanding story questions correctly, errors in transforming story questions into mathematical sentences, and errors in writing the final answer.

Abstract

The two indigenous Makian languages, Western Makian (Makian Luar) and Eastern Makian (Makian Dalam/Taba), stem from two different language families in North Maluku. The indigenous Makian people are typically ignorant of the riches of values and knowledge reserved in their language and culture, including mathematical content. Therefore, through an ethnography approach, this study identifies mathematical terminologies (natural numbers, fractions, number operations, indefinite quantifiers and adverbs of time) that exist in indigenous Makian languages. Data Collecting was conducted through in-depth interviews with indigenous community leaders and some primary literature reviews, then analyzed qualitatively. The mathematical language that has been identified along with the context of its use can be a good entry point and a mean-ingful material in integrating indigenous languages and cultures in mathematics learning.
