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
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
In the Industrial Revolution Era of 5.0, when the role of human resources play an important role, the binary gender distinction between man and woman shall be adapted to the challenges in the society. The role of woman in Communities which is based on Indigenous Knowledge and Culture has been considered as a gender biased as woman was seen to be sub-ordinate to the role of man in terms of their role between public and domestic. However, the practice of some Local Institutions in the Sunda Region of West Java, i.e. Gintingan and Perelek, have demonstrated that the women predominantly play an important role in the community. Using a qualitative method of survey of literature, this paper attempts to elaborate that although in Sundanese Culture, the patriarchic role in the society between man and woman women has been dominating the tradition, however the practice of some local institutions have demonstrated that there is a gender empowerment among Indigenous Communities which show that the local people have been negotiating the gender role in the Society.

Abstract
High-level radioactive nuclear liquid wastes (HLLW: radioactive metal ions in 2 M nitric acid solution) are generated in the reprocessing of spent nuclear fuels or in the decommissioning of nuclear reactors. In the process of producing the vitrified objects containing the wastes by using a glass melter, platinum-group metals (PGMs) [especially, ruthenium (Ru), rhodium (Rh), and palladium (Pd)] and molybdenum (Mo) cause serious problems: PGMs tend to be accumulated on the sidewall surface of the melter, whereas Mo compounds, so called yellow phase, are formed in the vitrified object. These issues result in (i) degradation of vitrified objects due to heterogenization and (ii) an increase in both disposal space and processing costs in conjunction with additional vitrified rods obtained by flushing the glass melter. To solve these issues, we have developed a process for efficient removal of PGMs and Mo from HLLW prior to introducing into the glass melter, using metal hexacyanoferrates (HCF) as a sorbent [1-3]. It is important to reveal the sorption mechanisms of PGMs and Mo for design of high performance HCF sorbents. In this talk, we will present the results on the sorption characteristics of Prussian blue (PB) nanoparticles, one of the HCFs, to the above metal ions in nitric acid solution, obtained using various spectroscopies and first-principles calculations.

Abstract
This research was conducted to explore the relationship between formal mathematics and Lingko, a system of traditional agricultural land distribution in Pocoleok, Manggarai-NTT Regency. Lingko was interesting to study concerning mathematics because of the philosophical values contained in lingko and the lingko sharing ceremony. This research focused on two things, namely: (1) how the distribution of ulayat land, Lingko, was mathematically reviewed while still paying attention to cultural values, and (2) how the community practiced mathematical concepts in the distribution of Lingko. The first focus of the problem was to uncover the mathematical activity of the distribution of ulayat land, Lingko, which was unknowingly carried out by the Pocoleok, Manggarai indigenous peoples. Knowledge gained from this first study might produce a new approach to learning mathematics, both from a mathematical or mathematical education perspective. The second focus of the problem seeks to reveal the extent to which the basic concepts of Manggarai culture (following understanding) to solve mathematical problems faced in the reality of life. This second study provides more space for cultural-based mathematics learning, namely how to understand mathematical concepts based on contextual issues that arise in Manggarai culture.

The survey implicate 36 eleventh grade students of 17 years old, test of logical thinking (TOLT), an essay MR test,a SRL scale. By using TOLT, the survey investigated many students with 17 years old had not reached formal cognitive stage, namely 19 % students at formal stage, 25 % students at transition stage, and rest 56% students at concrete stage. In addition, survey invented that entirely students obtained MR at very low grade level, and according to student-s cognitive stage, formal students obtained higher grade MR than the grade of transisiton students and concrete students. Even if, those grades were still at low and very low level. Either entirely or based on student-s cognitive stage there were no different grades on student-s SRL and those grade were fairly good level. SRL at fairly good grade level, transistion stage students attained MR and SRL at medium grade Other finding, there was medium association between cognitive stage and MR, but therewere no association between cognitive stage and MR, and SRL and between MR and SRL. In general, these findings were, that in normal condition formal cgnitive stage will reach by students in 12 -13 years old, or in 13-14 years old, even in specific condition in 19 – 20 years old; and that formal students possess higher abilities than concrete students on completing HOT tasks such as MR tasks which needed formal operational thinking.

Abstract
The aim of this study was to examine the achievement and improvement of MLA of junior high school students who obtained a CA and obtained CL. The method used is quasi-experimental design with a nonequivalent control group. This research was conducted in SMPN in West Bandung Regency with a sample of grade 8th students as many as 33 experimental class students and 27 control class students. The instrument used was the MLA 3rd level test as many as 2 items and 4th level as many as 3 items. The data analysis used was the Mann-Whitney U test. The results of the study found that 1) MLAs initial in both classes was the same; 2) the average posttest that gets contextual learning and those who get regular learning is quite different; 3) Mann Whitney U test scores on the posttest and normalized gain obtained Sig. = 0,000 < 0,05, then Ho is rejected. This means that the achievement of MLA of students who get CA is better than those who get CL. The same gain also in the normalized gain, Sig. < 0.05, meaning that the increase in MLA of students who get CA is better than those who get CL.

Abstract
This study aims to determine the difficulties experienced by junior high school students on algebraic concepts and the factors that cause difficulties in understanding algebraic concepts. The approaches and methods used in this study are qualitative approaches and naturalistic methods. The study was conducted at one of the schools in the Karawang district with the subject of the teacher and 9 students of class VIII that fit the criteria. The instruments in this study used a description test of 7 questions related to the ability to understand concepts and non-test instruments in the form of interviews, observation sheets, and field notes. The results of the data analysis showed the most dominant difficulties experienced by students, namely the indicators applying and analyzing with very high difficulty categories. These difficulties are influenced by several factors, including poor physical health, impaired sensory function, low interest in learning and student motivation, not mastering basic and classroom abilities that are not conducive. Alternative learning that can be done to minimize the difficulty of students in understanding the algebraic concept is to be able to use media or teaching aids and create a pleasant learning atmosphere.

Abstract
The purpose of this study was to examine the problem of achievement and improved critical thinking skills and dispositions mathematical high school students between those who use the scientific approach to integrating brain based learning with a scientific approach , examining the association between variablesand an overview of student performance. This study is an experimental study with a design pretest-posttest design. Sampling in this study using purposive sampling technique . The instruments used were tests and non-tests , the test instruments included tests of mathematical critical thinking skills while the non-test included attitude scale tests Student mathematical disposition . The results showed that the achievement and improvement of critical thinking skills (CTS) with a scientific approach to integrating Brain-based Learning (SAIBBL) better than class with scientific approach (SA). Mathematical Disposition (MD) student in the classroom with using learning (SAIBBL) better than students in class with SA. There is a strong association between CTS and MD . The overall picture of student performance with SAIBBL is superior and students are more active in learning. These results prove that the use of SAIBBL is better than SAI.

Abstract
This study aim to know the effect of active learning model Guided Note Taking (GNT) on student-s critical thinking ability for work and energy subject in senior high school. This study was held in Senior High School 77 on March 2019. This research used a quasi experimental method with a nonrandomized pretest-posttest design. The sample used purposive sampling, so the experimental class and control class were obtained. Before the research started, a pretest was given to know both classes have the same condition. The results showed that the pretest average value of experimental class was 43,25 while the control class was 42,75. This research instrument was posttest essay-s type with 10 questions. Prerequirement test used normality test by Chi-quadrate formula, because X2hitung≤X2table (4,58≤11,070) on experimental class, and X2hitung≤X2table (4,72≤11,070) on control class, so data was normally distributed. Homogenity test on α=5% and n=36 got that Fhitung≤Ftable (1,427≤1,757), so data was homogen. Based on hypothesis test by t-test with α=0,05 and dk=n1+n2-2, got that thitung>ttable (4,278>1,667), So, H0 is rejected and Ha is accepted. Then, the conclusion is student-s critical thinking ability who learn with Guided Note Taking model higher than direct instruction model and also Guided Note Taking has an effect on student-s critical thinking ability.
