Abstract
Human Papiloma Virus (HPV) is one of the viruses that can cause cervical cancer. However, vaccination can prevent such virus. The spread of the virus on cervical cancer can be modeled in SI model, however such model has not produced accurate result. The development and extension of the model into S1S2IRC with S1 denotes the population age 0 – 10 years and S2 represent the population over 10 years which is susceptible to HPV infection. The results produces a disease free and endemic equilibrium points. The analysis on the equilibrium points yields that the disease free equilibrium point will be asymptotically stable for R0 < 1 and R0 > 1 for endemic equilibrium point. The results indicate that the bigger the probablity of human prone to the HPV virus the bigger the chance of these individuals be infected by the virus. Therefore vaccination is required to protect the virus infection.

Abstract
The purpose of this study is to analyse the science students- Grade Point Average (GPA) on the basis of admission recruitment systems, gender and the origin of high schools. The research was conducted in the Faculty of Science and Engineering Undana. The anaysis focused on the first year students of the program to determine whether there is a significant difference in the GPAs on the admission grounds, gender and where their high schools were from. This was a survey research with cross-sectional approach, where data was taken at the same time period. The results indicate that students admitted through selection based upon secondary high school grades- (SNMPTN) perform nearly as well as those admitted via SBMPTN and Independent selection process. In addition female and male students produce indifferent GPAs. The analysis also revealed that the origin of students- secondary high schools do not affect significantly in students- academic performance in their first year university. This contradicts to the community assumption that students admitted through particular admission process and from particular areas in the province perform better academically than others.

Abstract
There are many educational applications nowadays, which permit students to strengthen theoretical and/or numerical concepts as an interactive approach. This research presents an educational application to support acid-base titration “self-learning” in flipped science education. This educational application is based on an ad-hoc open MATLAB code, which aims to create acid-base titration curves as self-learning in an interactive and collaborative layout. With this flipped educational application, students can practice and repeat comprehensive titration alternatives, i.e. strong, weak or polyfunctional titration acids and bases. Also, for each titration, each compound in different concentration can be chosen as the titration for the science education. The results show the proposed educational application as “self-learning” plans the titration curve, the former curve derivative and the numerical results. Particularly, students can have the opportunity to compute and analyze the titration-s final point graphically and numerically. Therefore, this flipped educational application is a possible and practical method to develop the fundamental concepts of acid-base titration via the numerical exercise practice supported by computer-based design.

Abstract
This study aims to determine and describe students mathematical problem solving abilities in geometry material, namely to build a flat side space. Based on the results of the TIMSS and PISA studies and literature studies indicate that there are still many students who have difficulty in the cognitive process to understand problems and solve problems in word problems. This fact raises this research which aims to investigate the ability to solve problems and difficulties carried out by students in solving material problems in building flat side spaces. This research is qualitative research, involving 26 one of the junior high schools in Bandung which was selected using random sampling techniques. Analysis of the ability to solve problems in this study is based on Polyas steps, namely understanding the problem, devising the plan, implementing the plan and looking back. Data collection techniques used in this study were written tests and interviews. Data were analyzed descriptively. The results of this study indicate that there is a relationship between students problem solving abilities with reflective and impulsive cognitive styles. The results of this study indicate that Impulsive students tend not to go through the stages of planning completion, error calculations, and reluctant to re-examine the solutions that have been found. Unlike the case with Reflective students.

Abstract
Students of Primary School Teacher Education Study Program generally have a universal high education background. In science course, students tend to do the learning process individually so that it results in uneven learning achievement. There must be an effort by lecturers to improve the skills and interests of students in science course, so that students increase in solving various learning problems, especially science. Thus students who have less academic ability to learn will improve their academic abilities. Thinking skills and science processes must be developed through science learning with certain models to foster the achievement of students to think creatively, innovatively and productively. Practicum method is a very effective method for science learning, because practicum helps students as prospective teachers to find answers with their own business based on the actual data. Practicum can be done is macro scale, in this case the weakness for science practicum is high cost. The purpose of the research is to increase students interest and skills using the micro-scale practicum learning method in the Chemistry study course. The research subjects were 209 students of the Pakuan University Semester III Primary School Teacher Education Study Program. During the learning process, observations about student cooperation at the time of the practicum are conducted. The observation results for each cycle were evaluated as a reflection material in the next cycle to improve students skills and interest in accordance with the set targets. Data analysis was conducted in quantitative descriptive. The practicum material that is applied is material in the subject of Chemical study course with a micro scale. From the results of the T-test, it was found that there were significant differences. This means that the understanding of the concept and Science Process Skills (KPS) increases after prospective teacher students experience the practical learning process of Chemistry study course material on a micro scale. From the results of the average value of understanding the concept, increasing from 62.42 to 86.68 and science process skills increased the average value from 56.19 to 87.86. 94% of prospective teacher students respond positively, that is, agree and strongly agree that the Chemistry study course process with a micro-scale practicum can improve science process skills and understanding the materials in the study subjects for college student of Primary School Teacher Education Study Program.

Abstract
The development of information and communication technology (ICT) has influenced various life activities including human behavior. The use of this technology has increased productivity, but this technology is still deficient to use in education. The teacher must innovate the learning environment to be more comfortable for generally millennial students. One of the learning innovations is the application of the flipped classroom concept. This concept still gives teachers room to face to face in class but also utilizes ICT in activities outside the classroom. From a variety of previous research studies, the application of this concept has a positive impact on various competencies in students. This study aims to see the impact of applying the flipped classroom to improving students critical thinking skills. The research design was the pretest-posttest controlled group design which consists of three groups taught different learning. Teacher applied direct instruction learning at the control group. Two other groups taught using a flipped classroom approach or online using Google Classroom. The participants of this study were 10th-grade students in physics subjects. Samples are taken randomly simple to determine groups. The analysis technique used is ANOVA to know the effect of learning strategies on critical thinking skills. Measurement of critical thinking skills is carried out using critical thinking test questions in the form of descriptions that have previously tested for difficulty and power of difference.
