Survival  analysis  is  a  statistical  technique  used  to  analyze  the  data,  aims  to determine the variables that affect the outcome of a beginning to end the incident. One model of survival is a cure model is useful for estimating the proportion of patients who recover and the probability of survival of patients who did not recover until   the   deadline   given.   Analysis   on   Cox   regression   cure   model   Hazard Proportional with Maximum Likelihood Estimates and Algorithm Expectation Maximization (EM). Keywords: Cox Proportional Hazard Cure Model, MLE, EM algorithm, likelihood ratio test, Wald test. 

Several fire experiments have been performed using carbon fiber reinforced (CFR) composite plates exposed to fire produced by a standard burner. The temperature evolution of both faces of the plate has been recorded by a two infrared camera system providing spatially referenced and synchronized images. The camera imaging in the "hot face" has been spectrally tuned [1] in order to minimize the flame effect on the measurement. Different abrupt changes in the temperature time evolution on both faces under a constant fire load have been observed as a pattern. The abrupt temperature time evolution changes and abrupt degradation state changes during fire test have been connected [2]. In order to reinforce this link between degradation state and temperature evolution, studies at high temperatures using conventional techniques have been carried out [2]: thermogravimetry and differential scanning calorimetry.

The partners of this Community Service Program are students from SMP Negeri 7 Padangsidimpuan. The partners' problems are as follows: 1) Students' difficulty in understanding mathematics subjects, 2) Students' low interest in studying mathematics, 3) Students' perspective which considers learning mathematics to be difficult and boring, 4) Low ability and skills of some teachers in presenting teaching material as interesting as possible and 5) Students' economic limitations to take part in tutoring in terms of studying mathematics material outside of school. To address these problems, we are interested in holding a Community Partnership Program (PKM) in the field of educational services. This program will help students face and solve problems related to learning mathematics. Therefore, students in the process of learning activities need study guidance by experts to overcome problems related to learning mathematics. Thus, this activity was carried out as an effort to erase the impression that mathematics is a difficult and boring lesson (Math Phobia) so that it becomes an easy and fun lesson (Math is Fun). It is hoped that all programs implemented will lead to improving mathematics learning outcomes. The results achieved through this activity were the formation of a teacher working group (KKG) with 2 to 5 members each, based on the distribution of teaching class levels. The teachers' knowledge and skills regarding cooperative learning models combined with mathematical approaches have increased from the "fair" to "good" category.
