Abstract

This article examines the estimation of spline regression, especially its use in longitudinal data. Longitudinal data is data obtained based on observations made as many as n objects that are independent with each object being repeatedly observed in different time periods and between observations in the same object are dependent besides longitudinal data is data that can distinguish the diversity of responses caused by The regression curve of the spline was estimated using the least squares. It can be seen that the estimation of the spline regression curve for longitudinal data is a class of linear estimation in response observations and is highly dependent on the knots point k1,k2,...,Kn

Abstract

To find out the relationship between two or more variables, regression analysis can be used. The definition of regression analysis itself is a data analysis method that utilizes the relationship between two or more variables. One concern in regression analysis is one of them is the standard error of estimation of the regression coefficient. In a regression there is already a formula for estimating standard errors. In addition, the standard error can also be estimated by the resampling method, which is bootstrap. Bootstrapping is very useful as an alternative to estimating parameters or standard errors when researchers feel hesitant to meet the assumptions in their data, for example the data are not normally distributed. In addition, bootstrapping is also useful when parametric inference requires a very complicated formula for calculating standard errors (Widhiarso, 2012). In this paper we will compare the standard error estimates obtained through existing formulas with the standard error estimates obtained through bootstrap resampling.

Abstract

This qualitative case study research deals with the implementation of the 100 Mosques / Musalla movement which socializes the MUI fatwa number 5 of 2010 concerning the Direction of the Qibla in Sleman Regency. by taking two districts to represent the conditions of urban and rural communities. The data collection methods are involved observation, documentation and interviews with 10 informants from community leaders in the two regions. Some people reject change because of their belief in the myth of the ijtihad of their predecessors, besides considering technology not as a means to perfect worship, including measuring the direction of the Qibla. However, most of the changes due to the certification of the mosque's Qibla direction do not require changes to the building, but only adjusting the prayer lines (saff) in the mosque. The dissemination of astronomical technology, which is understood as a form of ijtihad, can be done so that changes and developments that occur in the direction of the mosque's qibla can be accepted by the community.

Abstract

Multiple myeloma is an infectious disease characterized by the accumulation of abnormal plasma cells, a type of white blood cell, in the bone marrow. The main objective of this data analysis is to investigate the effect of Bun, Ca, Pcells and Protein risk factors on the survival time of multiple myeloma patients from diagnosis to death. In the survival data analysis, the observed random variable T is the time needed to achieve success. To explain a random variable, the cumulative distribution function or the probability density function can be used. In survival analysis, the function of the random variable that becomes important is the survival function and the hazard function which can be derived using the cumulative distribution function or the probability density function. In general, it is difficult to determine the survival function or hazard function of a population group with certainty. However, the survival function or hazard function can still be approximated by certain estimation methods. The Kaplan-Meier method can be used to find estimators of the survival function of a population. Meanwhile, to find the estimator of the cumuative hazard function, the Nelson-Aalen method can be used. From the variables studied, it turned out that the one that gave the most significant effect was the Bun variable, namely blood urea nitrogen levels using both the exponential and weibull distribution. However, by using the weibull distribution, the presence of Bence Jones Protein in urine also has a quite real effect

Abstract

The purpose of implementing community service is to encourage active participation of mosque takmirs in Bangunharjo Village, Sewon District, Bantul Regency to strengthen their role in handling tectonic earthquakes, especially mitigation. For this reason, activities are directed at enriching knowledge and technology about reducing the impact of earthquakes on the community in a sustainable manner by mosque leaders and administrators so that their role can be effective in mitigation activities. The appropriate participatory approach is an option in carrying out debriefing to motivate mosque administrators to be fully involved in mitigation activities as well as readiness to act and coordinate when an earthquake occurs. Important notes from the community that can be followed up are, among others, the need for assistance is very real, especially from information and technology in handling earthquake problems and strengthening socialization in the form of a curriculum that is more permanent and easy to implement in mosques, especially for children studying in TPA and congregation recitation. This segmentation is expected to be the success of disaster mitigation programs, especially those relating to earthquake mitigation issues related to the religious sector.

Abstract

This study attempts to explain what distribution of opportunities is in accordance with population growth if a family must have sons and evaluate policies based on the data obtained. The distribution of opportunities according to population growth if a family must have sons is a geometric distribution. For n families, the binomial distribution is used to measure the success rate of the government. If the chances of having a baby boy are high, then the chances of the one-child policy will be successful. In addition, the one-child policy in China was a policy implemented during the Deng Xiaoping administration in 1979 until it was finally abolished at the end of 2015. The decision to abolish this policy is of course a very interesting matter because this policy has been implemented for more than three decades and has succeeded in driving economic growth and improving the standard of living of the Chinese people. After more than three decades of implementation, various social and economic impacts have been felt by China as a result of the one-child policy. The low fertility rate in China, the imbalance of the sex ratio, and the aging population are new problems facing China because of the implementation of this policy. Taking into account these effects, the Chinese government officially abolished the one-child policy and implemented a new policy that allows every couple in China to have two children

Abstract

At the time of the Covid-19 pandemic, all learning was carried out online or online learning, while schools and students had to follow the existing curriculum in their schools, which of course not all of their lessons were happy. Mathematics is one of the subjects that is always a scourge for students, regardless of those who enjoy mathematics. The reasons vary, some say the lessons are difficult to understand, students are not interested in learning mathematics, the teachers are boring, and so on. So that many parents of students who provide additional tutoring for their children by hiring math teachers, in the hope that their children are mathematically intelligent. This study aims to examine the effect of using animated interactive multimedia on students' understanding of the concept of understanding mathematical concepts. The population of this study were students of class VII MTs Darul Ulum Muhammadiyah Galur even semester of the 2019/2020 school year. Of the five existing classes, two classes were taken randomly as samples with one class as the experimental class and one class as the control class.

Abstract

The main elements in Islam are faith, worship and morality. Actually all three are closely related to mathematics and its education for students. The novel Guru Aini is one of the books that seeks to integrate the understanding of the Islamic faith in learning mathematics by the mathematics teacher who is the main play. Through a literature review, it can be concluded that the educational values of Islamic faith contained in the novel Guru Aini (GA) by Andrea Hirata are: strengthening faith, trust, and belief. So what is meant by aqidah is a belief that pierces or is knotted in the heart. Tauhid or aqidah is a value that must be owned by an individual. The value of monotheism or aqidah is found in the form of limit and geometry concepts in the GA novel that are relevant to Tauhid Rububiyah.
