Publisher : Postgraduate, Universitas Negeri Semarang, Indonesia

The research aims to: analyze student's misconception on solubility and solubility product constant (Ksp) using the instrument of three-tier multiple choice test, and know the percentage of student's misconception. The research method used a mixed method with sequential explanatory strategy. Data collection technique was collected by diagnostic test using 20 questions of three-tier multiple choice that was completed by reasons and level of confidence, then the result of student's answer was analyzed. The result of the research shows that the diagnostic instrument test of three-tier multiple choice has fulfilled valid and reliable criteria. The implementation diagnostic instrument of three-tier multiple choice  shows misconception percentage of solubility material was 5,272%, solubility product constant (Ksp) was 7,339%, the effect of same ions was 2,025%, the effect of pH on solubility was 4,597%, and sub-material of Ksp and the reaction process of sedimentation was 9,870%.

Skills in the learning process are needed by students to be able to shape and develop the character possessed. This study aims to identify basic science process skills of students assisted practical worksheet based on multiple representations as media. This research was conducted by observation method that was done at the time of practicum activity by using an observation sheet and test method with response test. Students did practicum with practical worksheet media equipped with basic science process skills indicator and multiple representation level. Then the students worked the question with the basic science process skill indicators in it. Based on the analysis of the observation result, the basic science process skills profile of students in SMAN 11 Semarang was included in the high criteria with a range of 68 to 84. The criteria for each basic science process skills indicator were also analyzed from practicum 1 and practicum 2 which is high for indicators to observation, classifying, measuring, inferencing, predicting and knowing the relation of numbers and very high for indicators communicating and knowing relation between space and time. It can be concluded that students have demonstrated proficiency profile of basic science process. This research can be used as a reference for teachers and other researchers to improve student’s basic science process skills on different subjects.

This research was a mixed method with the design of sequential explanatory strategy. This research aims to identify student misconception on buffer solution material and obtain student response to multiple representation-chemoentrepreneurship (entrepreneurship in the chemistry field) teaching materials. Research subjects were 114 students from grade XI MIPA 3, XI MIPA 4, and XI MIPA 5 SMA Negeri 12 Semarang academic year 2017/2018. Three-tier multiple choice diagnostic test obtained from the research data amounted to 20 items, questionnaire to know the student's response to teaching materials, and interview to confirm student's answer. The result of the validation of teaching materials by three validators shows that the teaching materials of multiple representation-chemoentrepreneurship are very suitable to be used in chemistry learning with an average score of 190.33 from 212. The average score of the questionnaire is 28,026 with proper category and reliability of 0.906. The misconception profile obtained is the definition and the properties of the buffer solution 3.421%; the components of buffer solution 2.149%; working principle 2.632%; pH of buffer solution 3.596%; and the role of buffer solution 0.965% with a total misconception 12.763%.

Science process skills are indispensable for educators in the world of education or in everyday life that includes observing, categorizing, interpreting, forecasting, questioning, formulating hypotheses and communicating. The aim of this research is to develop of inquiry-based chemical practicum green chemistry-oriented for improving the students' science process skills in a colloid material. This research is a type of R & D research with One Group Pretest-posttest Design design applied to test the application of practicum as the product of development. The criteria for the success of this study are valid practicum, increasing KPS and getting a positive response from learners. Research data obtained by observation method, documentation, questionnaire and test. Device validation results obtained valid criteria (3.8 of 4). The results of early practicum KPS were in enough and fewer categories, improved on the final lab in the good and excellent category. The average of cognitive learning outcomes of the broad test classes is 79.20 (> of KKM) and the proportion of classical learning completion is greater than 80% or 24 of the 30 students reach the KKM. Students respond positively to the practicum in the "strongly agree" criteria.

Analysis Concepts Redox Using Multiple Representation Based Test Instrument with Computer Based Test (CBT) Model Nada, Ella Izzatin; Supartono, Supartono; Mursiti, Sri; Susilaningsih, Endang

The research was designed as the method of R&D  with the 4D  model,  define,  design, develop and disseminate. The purpose of this research is to develop a diagnostic test instrument two-tier with CBT to diagnose students' understanding profile. The test instrument can be used for the analysis and understanding of the concept Redox with the interpretation of the combination of the students' answers with the class understand the concepts, misconceptions, guessing, do not understand, and do not understand. The results of the feasibility test instrument indicate that the content validity of the category feasible with reliability 0.79. Profile of understanding the concept of students showed which scientific knowledge of which 9 out of 35 students (26.86%), positive misconception that 2 out of 35 students (4.14%), negative misconceptions is one of 35 students (2.43%), the misconception is one of 35 students (1.86%), lucky guess that is one of 35 students (3.71%), lack of knowledge that 12 of 35 students (34.86%), and did not know that 9 out of 35 students (26.14%) the concept of Redox.
