#### Abstract

A permutation group is a group of all permutations of some set. If the set that forms a permutation group is the n-first of natural number, then a permutation group is called a symmetry group. There is another type of group, i.e., a cyclic group and a dihedral group, and they are a subgroup of a symmetry group by numbering the vertices of the polygon. Sasirangan is the traditional batik from the South Kalimantan. There are 18 traditional patterns. All the patterns make some polygon. Because of this, the purpose of this research is to investigate the type of group that forms the patterns of Sasirangan. First, the authors give the procedure to investigate the patterns of Sasirangan, then use that procedure to the patterns of Sasirangan. The result of this research is the patterns of Sasirangan form cyclic groups C_1  and C_2, and dihedral groups D_2, D_4, D_5 and D_8.

#### Abstract

Regression analysis is a metodh for investigating the relationship between the dependent variable (Y) and independent variables (X). Logistic regression is a regression model that used related to the qualitative Dependent variable. If the Logistic regression influenced by factors of the location of each point from observation where the data is collected, it will be a Geographically Weighted Logistic Regression (GWLR). In the case of insecurity rate model of dengue fever has two or more categories, so that this case can be resolved by GWLR. This research aims to clarify the procedure of testing the parameters GWLR model and form insecurity rate model of dengue fever with GWLR method in Banjar Regency. Dependent variable with catagoric is Insecurity rate of dengue fever ( ) and independent variables is the population density ( ), the distance from the capital of the subdistrict to capital of regency ( ), fogging per subdistrict ( ), the percentage of households living clean and healthy ( ), pesentase healthy homes ( ), the percentage of access to decent sanitation ( ). The results from this research are estimate parameters using Maximum Likelihood Estimation method and presented in the form of thematic map that shows not all dependent variables give influence on Insecurity rate dengue fever

#### Abstract

Penelitian ini bertujuan untuk mengukur efektivitas pembelajaran aljabar dengan menerapkan model discovery learning dengan pendekatan etnomatematika. Konsep etnomatematika yang dimaksud adalah dengan mengaitkan materi tentang grup dengan pola kain sasirangan yang merupakan kain khas dari Kalimantan Selatan. Respon mahasiswa atas proses pembelajaran tersebut diamati dari persepsi selama pembelajaran berlangsung dan hasil penilaian yang diperoleh setelah pembelajaran. Persepsi mahasiswa dirangkum melalui kuesioner yang didalamnya memuat komponen penilaian untuk dosen pengajar yaitu aspek pedagogis dan profesional, sedangkan tingkat pemahaman mahasiswa diukur melalui butir-butir pertanyaan yang memuat aspek afektif dan kognitif. Aspek psikomotorik dievaluasi melalui penilaian video pembelajaran yang dihasilkan mahasiswa. Efektivitas pembelajaran terukur melalui signifikasi peningkatan nilai ujian sebelum dan setelah metode pengajaran diterapkan. Subyek penelitian ini adalah mahasiswa peserta pembelajaran mata kuliah Struktur Aljabar. Dari hasil penelitian menunjukkan bahwa pelaksanaan pembelajaran mata kuliah Struktur Aljabar dengan pendekatan etnomatematika telah memberikan peningkatan kemampuan mahasiswa yang signifikan baik dari sisi kognitif, afektif dan psikomotorik. Hal ini terukur dari respon mahasiswa dalam angket pembelajaran, bukti penyelesaian tugas video pembelajaran dan hasil nilai yang diperoleh mahasiswa. Penilaian untuk dosen pengajar juga memberikan hasil yang positif dari sisi pedagogis dan sisi profesionalitas.Improving the ability of mathematical understanding can be conduted by building different learning nuances. If so far the learning process has focused more on the teacher/lecturer (teacher center), a solution is needed to improve student understanding, one of which is by applying discovery learning learning techniques, where students can find their own formulas in learning & reasoning. Along with the desire to raise cultural values in the learning process, the ethnomathematical approach to learning is one of the best solutions to motivate students. This method is a collaborative discovery learning model with an ethnomathematical approach. namely the sasirangan cloth. After taking an ethnomathematical approach in the learning process, especially on topic of special groups, students are asked to provide an assessment of the learning process. The implementation of the Algebraic Structure learning course with an ethnomathematical approach has provided a significant increase in student abilities in terms of cognitive, affective and psychomotor. This is measured from student responses in learning questionnaires, evidence of completion of learning video assignments and the test results. Assessment for teaching lecturers also gave positive results from the pedagogical and professional side.

#### Abstract

The final assignment is one of the requirements to get a bachelorâ€™s degree for college students at the Faculty of Mathematics and Natural Sciences (FMIPA) University of Lambung Mangkurat (ULM). The average period of completion of the final assignment in the year 2015 until 2019 is 8 months, while the determined specification by the guideline is 6 months. The aim of this research is to identify the quality control of the final assignment completion process and whether satisfy the determined specification using statistical quality control. The used data in this research is the studentâ€™s final assignment completion period (variable data) and the nonconforming proportion of data (attribute data). The and control charts are used for variable data and control chart for attribute data and process capability analysis. The result of variable data is that the average period of final assignment completion is statistically in control with a control limit of months. For attribute data concluded that final assignment completion is statistically in control with a big average proportion that is . For the capability analysis process by index and value sequentially is and for the DPU value is . This shows that the completion period of the studentâ€™s final assignment of FMIPA ULM is not capable to fulfill the specified standard of the period.

#### Abstract

Time series forecasting is a method used to determine what might happen in the future based on information obtained in the past. One method used in time series forecasting is a Holt-Winters exponential smoothing method. This method can be used for time series data with trend and seasonality components. This method is based on three smoothing equations: overall smoothing, trend, and seasonal components. Holt-Winters exponential smoothing method consists of multiplicative and additive seasonality models. The method of this research is literature study by collecting and studying references that are relevant to the idea of this research, and then applying the Holt-Winters exponential smoothing method into data. The results of this research show that the multiplicative seasonality model of Holt-Winters exponential smoothing method can be used if data represent an increase in long-term and seasonal fluctuations which is the increasingly bigger with the increasing of observation time periods. These patterns identify the non-stationary of mean and variance. While, the additive seasonality model can be used if data show an increase in long-term and seasonal fluctuations that are relatively constant with the increasing of observation time. Time series forecasting is a method used to determine what might happen in the future based on information obtained in the past.

#### Abstract

Confidence interval is an interval between two value, where we believe that the parameter value lay within those interval. To express it, approximate interval were conducted. If the parameter value is unknown, probability will be use rather than exact value. Approximation that conduct express probability that an interval contain parameter value that we estimate. One of parameter value to compute is mean. One of well-known distribution is Poisson ditribution. The purpose of this study is to find approximate interval for the mean of random variable with Poisson distribution. The result of research is confidence interval for poisson distribution by using pivotal quantity method. Based on pivotal quantity method, approximate interval for the mean of poisson distribution with the size of a large sample is???????? ???? ????????????− ????????????????/2 ???????????????? ???????? < ???????? < ???????????? + ????????????????/2 ???????????????? ???????? ???? = 1− ????????
