Biodiesel fuel from waste cooking oil using zeolite catalyst
Authors: Fitriyah  
Published: April 2020

Abstract
The waste of household cooking oil is thrown away so that it causes environmental problems. Therefore, this problem must be responded to immediately, for example by processing household waste cooking oil into environmentally friendly biodiesel as an alternative method to address this problem. This household cooking oil waste treatment aims at reducing environmental problems, furthermore to discover a way for the waste of household cooking oil to be processed as an alternative fuel to replace diesel, which is biodiesel as a renewable energy source. This study aims to make biodiesel from household waste cooking oil to eliminate or reduce levels of free fatty acids (ALB) contained in used cooking oil catalyst, namely Zeolite Bayah catalyst, while the temperature and reaction time is a fixed variable esterification reaction. The results of this study indicate that the processing of used cooking oil using Zeolite Bayah catalyst can reduce the free fatty acid content contained in used cooking oil, and the physical characteristics of biodiesel generally meets the SNI-04-7182-2012 standard. So that it can be seen that the Zeolite Bayah catalyst influenced the process of reducing free fatty acids in used cooking oil, it can be concluded that some of the parameters are already included in the national standard 04-7182-2012, and it can be seen that the Zeolite Bayah catalyst density parameters obtained the results of 871, the density of NaOH catalysts obtained 862, while from the national standard 04-7182-2012, it was set at 850-890. Both of these results have met the standard for the quality of making biodiesel.

Published: April 2020

Abstract
The main purposes of the study are investigating the types and factors cause errors in using adjective clauses. The method of this study was descriptive qualitative method which focused to describe the types of errors and to describe the factors causes’ error. The subjects of this study were 20 students from the first Semester students of English Department of STKIP Muhammadiyah Sampit. In taking sample, the writer used snowball sampling. In collecting the data, the writer used four types techniques, they were observation, test, interview, and documentation. In data analysis procedure, the writer uses data reduction, data display, and conclusion drawing/verification. The result of this study showed the types of error made by First Semester students of English Department of STKIP Muhammadiyah Sampit in using adjective clauses classified into four categories. The highest error made by the students was misordering with frequency 85 (80,95 %). The second error made by the students was omission with frequency 9 (8,57 %). The third error made by the students was misformation with frequency 9 (8,57 %). The fewest error made by the students was addition with frequency 2 (1,90 %). Based on the analysis of the data, the factors that cause error in using adjective clauses classified into two factors. They are teacher and students’ factor. Teachers’ factor is caused by the competence of the teacher. Students’ factor is caused by overgeneralization and translation. It is suggested that for the students, they should learn and practice more how to use adjective clauses in sentences. For the teachers, they are suggested to explain more intensively about adjective clauses and provide additional teaching hours for the students who face difficulties and also, they are suggested to give the students more practice and exercise to add their knowledge about the kinds of adjective clauses sentences.

Conceptual Understanding And Procedural Knowledge: A Case Study on Learning Mathematics of Fractional Material in Elementary School
Authors: Salim Nahdi D , Gilar Jatisunda M 
Published: April 2020

Abstract
Learning theory sees conceptual knowledge as a source of students’ procedural knowledge in learning mathematics. This is supported by several previous studies which show that students learn conceptual understanding before procedural knowledge. So the researcher highlights the relationship that might occur between conceptual and procedural knowledge. Whether conceptual knowledge might have a greater influence on procedural knowledge than vice versa. This research is a qualitative research with a case study approach. The results showed that students who succeeded in fraction learning were able to combine conceptual and procedural knowledge well. It can be concluded that students with conceptual and procedural knowledge can develop good knowledge in learning mathematics.

Published: April 2020

Abstract
The ability of Chinese Literature graduates needs to be evaluated, so that the organizers of the Chinese Literature study program continue to update the courses taught at college. The ability of graduates can be seen from the results of treasure studies and the soft skills needed can be mapped. So far, the curriculum, and graduate competencies focus more on hard skills even though soft skills are also needed in doing a job. Therefore, this research was conducted to map the soft skills needed to do a job. Data collection was carried out from the input of 99 Chinese Literature graduates spread across three universities that have Chinese Literature study programs. From the input of the graduates, communication skills and teamwork are more needed in doing a job. Thus, policy makers are expected to consider a soft skill course that is beneficial for students in doing a job.

Abstract
This study aims to improve the KPS and students’ high cognitive abilities after the implementation of self assessment through research-based learning. The research method used is mixed methods with Sequential Exploratory design. The population of this research is the students of class XI one of the vocational competence of nursing skills in Cirebon Regency. The research sample consisted of two classes determined by purposive random sampling technique, namely control class amounted to 27 people and 27 experimental class. The results showed that the average of self-assessment of the experimental class students is 81% with the superior category. The result of observation of experimental class KPS based on teacher observation is 88% with superior category and observation result of control class KPS is 77% with competent category. Thus, KPS increases after the implementation of self assessment. The data of research result of high level cognitive ability obtained by giving cognitive test at cognitive level of C3 until C6 growth and plant growth material in the form of pre test and post test. The collected data were analyzed by using descriptive statistics and comparative inferential statistics 2 paired sample groups. The result of descriptive analysis shows that the average value of pre test result of experiment class is 45,74 and post test result is 82,96, N-gain 0,70 with high category. The mean value of pre test result of control class 54,72 and post test result is 67,22, N-gain 0,30 with low category. KKM Biology lesson in class XI is 70, this shows the average post test experimental grade above KKM and control class is still below KKM. The result of t test dependent on pre test score and post test of high cognitive ability obtained by significance value 0,00 (sig <0,05) hence Ho refused and Ha accepted. This proves that Self Assessment can improve students’ high cognitive abilities. Thus it can be concluded that the implementation of Self Assessment can improve the KPS and students’ high cognitive abilities on the material growth and development of plants through research-based learning.
