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.

Misconceptions of a concept in a lesson will have an influence in understanding the next concept. Having misconceptions that exist in learning can understand the nature of the misconceptions and consequently can help student learning progress. Therefore, a diagnostic test for misconceptions is needed, including the newest four-tier multiple choice and five-tier multiple choice. This research is a literature review that provides information systematically using the PRISMA method which often occurs in students' misconceptions in high school physics subjects. The data for this research are 60 selected articles from 2017-2021. The purpose of this study is to reveal the use of four-tier multiple choice and five-tier multiple choice diagnostic tests in physics and also provide a comparison of each instrument with the strengths and weaknesses of the four-tier multiple choice and five-tier multiple choice diagnostic tests. Furthermore, the use of multiple choice four levels (83.33%) and multiple choice five levels (16.67). %). In the use of the four-tier multiple choice physical material diagnostic test, which are often used in identifying misconceptions, are optical devices (12%) and energy businesses (10%). And the use of an additional five-tier multiple choice instrument diagnostic test that is often used is to present an overview or conclusion at the fifth level. However, each type of four-tier multiple choice and five-tier multiple choice tests has its own advantages and disadvantages in assessing students' conceptions

Misconceptions can be in the form of initial concepts, mistakes, incorrect relationships between concepts, intuitive ideas or naive views. From the explanation that has been described misconception is interpreted as an initial concept owned by students that is not in accordance with the generally accepted explanation as a result of the experience constructed by students. Misconception can also be called an alternative concept. This study aims to determine the misconceptions of Class X students of Natural Sciences 2 of SMA Negeri 1 Remboken on atomic structure material. Data collection uses questions in the form of a two-tier diagnostic test, which was tested on 20 students. From the results of the study concluded that students who understood the concept of 82.75%, and students who experienced misconceptions as much as 11.25% while students who did not understand the concept of 6% in the Atomic Structure material.

Difficulty understanding students' concepts needs to be known so that improvements can be made so that eventually students can master the concepts well. Misconception diagnostic tests can be an alternative to uncovering causes or factors of misconception in students. This study aims to develop a Four-Tier Test diagnostic test instrument to diagnose students' misconceptions on circular motion material. This research is a development study using 4D models.  The developed four-tier test diagnostic test instrument consists of 40 multiple-choice questions. The results of the content validation by five experts stated that the instrument was very feasible with an average percentage of 86,34%. Empirical trial results show as many as 40 valid diagnostic test items have enough to good power a level of difficulty and discrimination power. The reliability of the questions was analyzed using the Kuder Richardson formula of 0.785 with a high category. This instrument can be used to minimize the time spent in the process of identifying misconceptions because it is in the form of multiple-choice with varied questions.

Concept Understanding

The concept is an understanding of an individual or a group of people who is expressed in the form of a meaning that produces knowledge. Misconceptions of students that appear continuously will interfere with the formation of scientific conceptions and can affect student learning outcomes. Therefore it is necessary to analyze the misconceptions of students. One of the diagnostic tests that can be used is a two-tier multiple choice test or known as a two-tier multiple choice, the first level is the question being tested while the second level contains the reasons for the answer to the first level. This study aims to analyze misconceptions and determine the percentage of students' misconceptions on hydrocarbon material using descriptive methods. The subjects were 27 students of class XI IPA 2 in SMA Pertiwi 1 Padang. The research instrument was a Two Tier Multiple Choice diagnostic test by dividing students' conceptual understanding into the categories of conceptual understanding, misconception, and conceptual misunderstanding. The results showed that the percentage of students' conceptual understanding in the concept understanding category was 31%, misconception was 36%, and did not understand the concept by 34% on hydrocarbon material. Students' misconceptions on hydrocarbon material at SMA Pertiwi 1 Padang were categorized as moderate. Konsep merupakan pemahaman individu atau sekelompok orang yang diungkapkan dalam bentuk pengertian yang menghasilkan suatu pengetahuan. Miskonsepsi peserta didik yang muncul terus menerus akan mengganggu pembentukan konsepsi ilmiah dan dapat mempengaruhi hasil belajar peserta didik. Oleh sebab itu perlu dilakukan analisis miskonsepsi peserta didik. Salah satu tes diagnostik yang dapat digunakan adalah tes pilihan ganda bertingkat dua atau dikenal sebagai two-tier multiple choice, tingkat pertama merupakan pertanyaan yang diujikan sedangkan tingkat kedua berisi alasan atas jawaban pada tingkat pertama. Penelitian bertujuan untuk menganalisis miskonsepsi dan menentukan persentase miskonsepsi peserta didik pada materi hidrokarbon dengan metode deskriptif. Subjek penelitian ini adalah peserta didik kelas XI IPA 2 di SMA Pertiwi 1 Padang yang berjumlah 27 orang. Instrumen penelitian berupa tes diagnostik Two Tier Multiple Choice dengan membagi pemahaman konsep peserta didik dalam kategori paham konsep, miskonsepsi, dan tidak paham konsep. Hasil penelitian menunjukkan bahwa persentase pemahaman konsep peserta didik pada kategori paham konsep sebesar 31%, miskonsepsi sebesar 36%, dan tidak paham konsep sebesar 34% pada materi hidrokarbon. Miskonsepsi peserta didik pada materi hidrokarbon di SMA Pertiwi 1 Padang termasuk kriteria sedang.
