Abstract

In learning outcomes assessment activities, teachers play an active role in preparing measuring instruments. Competency measurement tools must have appropriate quality criteria used in measuring student competence. This study aims to determine the characteristics of the mathematical competency test instrument in terms of item validity, item difficulty level, item discriminating power and distractor function. The instrument developed is a competency test instrument for trigonometry material. The form of this instrument is multiple choice. The sample of this research is SMA Negeri 5 Yogyakarta. Analysis of the Trigonometry competency test items was carried out using qualitative analysis with the result that 85% in terms of material had good criteria, 82.5% in terms of construction had good criteria and 92.5% in terms of language had good criteria. Quantitative analysis of the Trigonometry competency test shows that 27 items (67.5%) have good validity, the test has a reliability value of 0.709 with good criteria. There were 26 questions (65%) with moderate difficulty level, 28 questions (70%) had good category discrimination, and 37 questions (92.5%) had good criteria for the distraction function.  Keywords:  validity, reliability, difficulty level, differentiating power

Abstract

The purpose of this research is to analyze the fluctuations and quantity of daily stock closing data of PT. Bank Central Asia Tbk (BCA) during the period from January 3, 2022, to December 30, 2022, and forecast the closing stock price in January 2023 using the ARIMA model. The research procedure was conducted step by step, including data collection, descriptive analysis, testing data stationarity, determining ARIMA model parameters, writing ARIMA equation models, conducting diagnostic tests on the best ARIMA model, and making predictions or forecasts. The analysis shows that the stock closing prices in 2022 fluctuated with an average range of Rp 7,214.29 - Rp 8,851.14 per share. The highest closing price occurred in November 2022, while the lowest occurred in July 2022. The forecast for the daily closing stock price of BCA from January 2 to January 31, 2023, using the ARIMA Model (1,1,0), ranges from Rp 8,550.00 to Rp 8,550.86. The MAPE value obtained from the forecasting result is 1.07%, indicating that the ARIMA model is highly effective in forecasting the closing stock price of BCA in January 2023. This research provides valuable insights into stock price fluctuations for stakeholders in the stock market. Keywords: fluctuations, ARIMA, stock closing prices, forecast.

Abstract

The cause of the low level of education in Indonesia, especially in students' literacy and numeracy skills, is the limited learning media used in schools. The aim of this research is to develop Pop-Up Book-based learning media to improve the literacy and numeracy skills of students at SD Negeri Cisarua 01, Bogor Regency. The ADDIE model consisting of the stages of Analysis, Design, Development, Implementation, and Evaluation is used as a research method. The data analysis technique used is the descriptive analysis technique. The data analyzed includes media suitability data from media experts and material experts as well as responses from students as test subjects. This Pop-Up Book media has a material validity level of 80%, and media validity of 88%. The effectiveness of the Pop-Up Book learning media from the students' pre-test and post-test showed that the value of tcount > ttable (12.786 > 2.056) and was significant 0.000 < 0.05, so Ha was accepted and Ho was rejected. So it can be concluded that there is a significant difference in learning outcomes before and after the application of Pop-Up Book-based learning media in the introduction of plane shapes and space shapes. To see the increase in the calculated Gain Test, the average result obtained was 0.6688 and was in the medium category. Based on the results of the analysis that has been carried out, it can be concluded that the development of Pop-Up Book learning media can improve the numeracy literacy skills of students at SD Negeri Cisarua 01, Bogor Regency. Keywords: Numeracy Literacy Skills, Ethnomathematics, Learning Media, Pop-Up Book.

Abstract

This research aims to explore the concept of geometry in mathematics in schools related to Plaosan Temple. This research was conducted at Plaosan Temple from January to July 2023. This research is descriptive qualitative research with an ethnographic approach. This research was carried out through observation, documentation and interviews to collect data. Observations were carried out directly at Plaosan Temple. Plaosan Temple is divided into two complexes, namely Plaosan Lor Temple and Plaosan Kidul Temple. Plaosan Temple is also nicknamed the twin temples. In the Plaosan Lor Temple complex there are several buildings including the main temple, Perwara Temple, Perwara Stupa, Mandhapa, Perwara Mandhapa Stupa, Fence, Kori Agung Gapura, and Dwarapala Statue. The informants in this research were cultural figures under the Central Java Cultural Heritage Preservation Center and junior high school mathematics teachers in Gunung Kidul. The data analysis technique in this research uses the Spradley model data analysis technique. The result of this research is the discovery of geometric concepts, especially flat-sided shapes in the Plaosan Lor Temple Complex, namely, triangle models, trapezoid quadrilaterals, rhombuses and parallelograms. From the geometric model of flat-sided spatial shapes, the concept of flat-sided spatial shapes was found in the artifacts and reliefs of Plaosan Temple Keywords: Ethnomathematics, Mathematics Learning, Geometry, Flat Side Building

Abstract

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. This disease represents a significant global public health challenge. Consequently, a stochastic differential equation model of tuberculosis has been developed. In this context, an analysis examines the impact of complete treatment on the disease-free population distribution, duration of disease-free status, and the probability of remaining disease-free. The analysis shows that as the rate of complete treatment increases, the probability of achieving disease-free status rises, the duration of remaining disease-free shortens, and the number of disease-free individuals grows over time. Keywords: Complete Treatment, Disease-Free Duration, Stochastic Differential Equations, Tuberculosis

Abstract

Gumelem batik is batik made by the people of Gumelem Village, Susukan District, Banjarnegara Regency, One of the typical Gumelem batik producers who still maintains the traditional method making batik is the “Wardah” batik house owned by Mr. Budi Triono. The typical motifs of this batik are the sekar jagad motif, the udan liris motif, the arjuna temple motif, and the dawet ayu banjarnegara motif. Batik cloth culture has been recognized as an intangible world heritage, but its benefits are limited to the cloth. It is still rare for people to use batik culture as a mathematics learning medium. Mathematics that combines cultural concepts with mathematical elements is called ethnomathematics. In this research, typical Gumelem batik motifs will be discussed mathematically using the concept of geometric transformation. The method used descriptive-qualitative, with an ethnographic approach. The result of the research is that, for several typical Gumelem motifs analyzed, it turns out that all of three motifs contain mathematical elements, namely geometric transformation. This research is aimed at developing mathematics teaching materials based on the culture of Gumelem village. Keywords: Ethnomathematics, Batik Gumelem, Geometric Transformation
