The Relationship

Abstract Acid-base is one of the materials that tend to be difficult for students to understand. Acid-base is a material that is conceptually solid and requires an integrated understanding of many of the concepts of introductory chemistry. This research is descriptive research that aims to find conceptions of students on acid-base subjects and asking about concepts that are considered troublesome according to their learning experiences. The subjects of this research were 31 students of class XI IPA 4 at SMAN 3 Pariaman. The instruments in this research are diagnostic tests and interviews. The result of this research is the students of SMAN 3 Pariaman have difficulties in learning about the acid-base subject with high category. The percentage of conceptions experienced by students in each indicator is 56.3% of students understand the concept, 20.8% misconception, and 22.9% do not understand the concept. In the second indicator, 45.2% of students understood the concept, 18.3% had misconceptions and 36.5% did not understand the concept. In the 3rd indicator, 35.5% of students understood the concept, 31.2% had misconceptions and 33.3% did not understand the concept. In the 4th indicator, 21.9% of students understand the concept, 27.7% do not understand the concept and 50.3% do not understand the concept. Meanwhile, the acid-base theory, the calculation of pH or pOH, and the relationship between the degree of acidity (pH) and the degree of ionization (a), and the acid equilibrium constant (Ka) or the base equilibrium constant (Kb) are considered troublesome knowledge because they can be conceptually difficult.

This research aimed at identifying the subject-verb agreement errors in students’ writing. This research applied a descriptive research. The data were collected through test and non-test instruments. Test instruments were conducted through writing test and non-test instruments were through questionnaire and interview. The data obtained from both test and non-test instruments were conducted by employing descriptive analysis. This research analyzed students’ narrative writing based on Surface Strategy Taxonomy proposed by Dulay, Burt and Krashen (1982). This result revealed the types of error in subject-verb agreement in the students’ narrative writing covering omission, addition and misinformation. In conclusion, the students involved in the research made a number of errors. It was found that the students’ ability to use subject-verb agreement in English was still low.

The Research was aimed to analyze the error on pronoun made by the eleventh grade students of SMA Katolik Cinta Kasih Tebing Tinggi in Academic Year of  2020/2021. The subject of this research consists of 30 students in XI-MIPA-1. The objectives of the study were (1) To find out the types of error made by students in using pronoun. (2) To find out what causes the students made such error in using pronoun. This research used qualitative approach with descriptive research. The errors were collected, identified, and classified based on the Surface Structure Taxonomy by Dulay. It was specified by four types of errors namely omission, addition, misordering, and misformation.The result showed (1) The most common errors made by the students were misformation (52,0%) or 88 errors. The second was error in addition with the frequency (35,5%) or 60 errors. The third error was omission (11,2%) or 19 errors. The lowest frequency of error was misordering (1,1%) or 2 errors. (2) The students made such errors in using pronouns because of their less motivation of learning, lack of knowledge about grammar and English language, and minimal use of media by the teacher during teaching learning process. The teacher should create an interesting teaching, so it that can increase the students’ interest in learning English.

Translation Errors

<p>This research aimed to identify types of translation errors and to find out the sources of errors (interlingual and intralingual errors) in Indonesian-English translation written by the students. The type of this research was descriptive research which used Error Analysis procedures to identify and analyze the students’ error. The findings showed that the types of grammatical errors made by the students in their translation were three types, namely global errors, local errors, and other errors. The most frequent error made by the students was local errors and the fewest error made by the students was other errors.  Then, this research revealed that mostly errors occurred in students’ translation were caused by intralingual error. Meanwhile, only few errors were caused by interlingual error. The errors occured due students’ incomplete knowledge of the target language.</p>

AbstractIn this paper, we present the Picard-HSS-SOR iteration method for finding the solution of the absolute value equation (AVE), which is more efficient than the Picard-HSS iteration method for AVE. The convergence results of the Picard-HSS-SOR iteration method are proved under certain assumptions imposed on the involved parameter. Numerical experiments demonstrate that the Picard-HSS-SOR iteration method for solving absolute value equations is feasible and effective.

AbstractWe prove that, for n ⩾ 2, any n-place Boolean function may be implemented by a two-pole contact circuit which is irredundant and allows a diagnostic test with length not exceeding n + k(n − 2) under at most k contact breaks. It is shown that with k = k(n) ⩽ 2n−4, for almost all n-place Boolean functions, the least possible length of such a test is at most 2k + 2.
