Abstract

Many researchers use Weibull distribution to analyze wind speed data parameters and so forth, but in this research Weibull distribution is used to analyze the frequency data magnitude of aftershock. We use different methods for estimating Weibull distribution parameters. Some methods are compared according to the mean square error (MSE) criteria to select the best method. The parameter estimation results from the data are then used to determine the mean and magnitude of the earthquake. Further data is depicted in a curve for analysis. The case study in this study uses an aftershock frequency data in Nabire district, Papua. After the test of conformity with Kolmogorov-Smirnov test, it is obtained that the data follows the Weibull distribution pattern. Further research results show that the best method among the three methods is the maximum likelihood method (MLE). Keywords: Weibull, Maximum Likelihood Method (MLE), Least Squares Method (LSM), Graphical Method, Kolmogorov Smirnov, Magnitude

Abstract

The team of the community engagement service chose to use the topic of multiplication in this activity because the classical topic is still a scourge for students at the elementary to intermediate levels. This leads to students' rejection of mathematics learning although there are various methods of counting, such as mencongak, sempoa, kumon and jarimatika. The challenge of creatively critical thinking becomes the main concept in the learning process/ activity development at SMA Yapis Nimbokrang. The learning approach using the geometric method is introduced and applied in solving simple multiplication problems. The data used to measure the success of the method are the results of the pre- and post-tests. Overall there was an increase in the results of the pretest to the posttest, namely 92% of students liked and could understand the use of the geometric method for multiplication. Also, there are about 22% of students who have not used the geometry method optimally although there is a slight increase in the results of their pretest and posttest. Thus, the use of geometric methods in solving simple multiplication problems at SMA Yapis Nimbokrang is considered successful.Keywords: Multiplication; Geometric-Mean; SMA Yapis Nimbokrang

Abstract

Technology plays an important role in life. Information and Communication Technology (ICT) has expanded educational options by enabling teachers and students to use technology to reorganize existing education and training systems. An adequate number of studies have identified the various benefits of implementing e-learning. However, not all institutions that implement online learning get the expected results. In addition, teachers in schools are not homogeneous. This study analyzes e-learning readiness in rural areas during the Covid-19 pandemic. This type of research is descriptive and quantitative. The subjects of this study were ten teachers, three IT staff, two foundation administrators, and 87 students from elementary and junior high schools. Data was collected using questionnaires and interviews. Data were analyzed using Aydin and Tasci's E-Learning Readiness Score, which describes learning outcomes. The results of this study indicate that overall, e-learning is ready to be implemented due to the leadership's commitment in the form of funds and policy support for the implementation of e-learning. Factors that need serious attention are technology infrastructure, human resources, and content.

Abstract

The Wairon is a traditional warboat of the Biak tribe, characterized by its unique symmetrical structure tailored for combat navigation. This research explores the mathematical principles embedded in its construction from an ethnomathematical perspective, addressing the gap in literature on how indigenous maritime engineering reflects advanced spatial reasoning. The study aims to document and analyze the symmetrical design elements of the Wairon to uncover how Biak boatbuilders apply geometric and anthropometric logic in practice. Using an exploratory qualitative method with triangulation, data were gathered through 12 in-depth interviews with cultural experts and elder artisans, direct observations of three traditional boat-building sessions, and literature analysis of maritime knowledge. Triangulation was applied by comparing themes that emerged independently across these three data sources. The collected qualitative data were analyzed using a thematic coding framework with multiple coding cycles, focusing on patterns of symmetry, measurement techniques, and structural logic. Codes were reviewed through peer validation and saturation was reached after the third data source. Symmetry in this study is operationally defined as bilateral congruence across a central longitudinal axis, as observed in the mirrored placement of najun (crossbeams), outriggers, pegs, and bow carvings. Evidence was gathered through measurements of spatial repetition, alignment consistency, and anthropometric mapping (e.g., arm span and fathom units) used by artisans during construction. Key findings highlight that the Wairon's design reflects a high degree of symmetry not only for aesthetic or symbolic purposes but also for tactical advantages in battle, allowing seamless directional shifts. The theoretical implications contribute to the expansion of ethnomathematics by contextualizing symmetry as both a cultural logic and a navigational solution, while practically, these insights provide a model for integrating indigenous design principles into STEM education and support initiatives for digital heritage preservation and virtual reconstruction of traditional technologies

Abstract

Modeling the distribution of Human Development Index (HDI) components is essential to uncover underlying disparities and guide targeted policy interventions. This study aims to analyze HDI data, focusing on the average length of schooling across 26 districts in Papua Province from 2010 to 2023, to identify the most suitable probability distribution model. Using the k-means clustering method, two main groups were identified based on the average length of schooling. Cluster 1 includes 11 districts with a Weibull distribution, characterized by a scale parameter of 8.9931 and a shape parameter of 16.1272, indicating significant variation in education duration. Cluster 2 consists of 15 districts with a scale parameter of 3.73006 and a shape parameter of 8.07662, showing a distribution with a long tail and greater variability. This study provides insights into the distribution patterns of education duration in Papua, which could aid policymakers in making more targeted decisions and allocating resources efficiently. The findings also highlight regional disparities and the need for specific educational interventions. These results are valuable for government entities, NGOs, researchers, and international donors interested in improving educational outcomes in underdeveloped areas. However, the analysis is limited by the scope of available data and the assumption of homogeneity within clusters.

Abstract

Penurunan fungsi organ-organ fisik pada lansia mempengaruhi derajat kesehatan lansia sehingga sangat rentan terjadi komplikasi penyakit. Penggunaan obat oleh pasien usia lanjut dengan komplikasi penyakit menjadi tantangan yang kompleks dan memerlukan pertimbangan cermat antara manfaat dan potensi bahaya. Perolehan dan penggunaan obat sekaligus dalam jumlah yang banyak oleh pasien komplikasi dikenal dengan istilah polifarmasi. Polifarmasi dapat menyebabkan permasalahan dan ketidakpatuhan dalam dalam penggunaan obat. Berdasarkan hal tersebut, perlu dilakukan penyuluhan DAGUSIBU untuk meningkatkan pemahaman lansia tentang pengelolaan dan penggunaan obat yang baik dan benar. Kegiatan penyuluhan dimulai dari tahap advokasi dengan pihak panti, observasi awal mengenai pola perilaku lansia dalam mengelola dan menggunakan obat, tahap pemberian materi dan tahap evaluasi. Hasil observasi awal diperoleh informasi bahwa beberapa perilaku lansia masih belum baik dan benar dalam mengelola dan menggunakan obat. Pemberian materi DAGUSIBU meliputi aspek perolehan, penggunaan, penyimpanan dan pembuangan obat yang baik dan benar. Hasil evaluasi menunjukkan lebih dari 90% lansia yang menjadi peserta kegiatan pengabdian telah memahami cara pengelolaan dan penggunaan obat yang baik dan benar. Melalui kegiatan penyuluhan ini, lansia di panti bina lanjut usia Sentani telah mendapatkan peningkatan pengetahuan dan pemahaman mengenai pengelolaan dan penggunaan obat yang baik dan benar. Penyuluhan ini diharapkan dapat membentuk karakter lansia yang mandiri dalam pemeliharaan kesehatan sebagai upaya peningkatan kualitas hidup.
