Abstract

This study aims to see the effect of the Guided Inquiry Learning Model on Student Learning Outcomes on the Material of Electrolyte and Non-Electrolyte Solutions of Class X Students at SMA Negeri 1 Batang Onang. The learning outcomes of high school students in chemistry are still relatively low, one of which is caused by the dominance of teachers in a less innovative learning process that makes students passive. The research was conducted at SMA N 1 Batang Onang with a research sample of two classes: class X MIA-2 (control class) with 16 male students and 12 female students, and class X MIA-3 (experimental class) with 14 male students and 13 female students. This research method is an experiment with a non-randomized group pre-test post-test design. The instrument used was an essay test of 5 questions. The results showed a significant increase in student learning outcomes after the application of the guided inquiry learning model. In conclusion, the guided inquiry learning model is effective in improving student learning outcomes in chemistry learning. The results of hypothesis testing using T Test (Independent Sample t Test). This is evidenced based on the calculation of hypothesis testing with an average test taken from the pretest and posttest scores that the results of the posttest independent sample t test with a significant level value (α = 0.05) obtained a significant value (2-tailed) of 0.008. The significant value (2-tailed) obtained is smaller than 0.05, so H0 is rejected and Ha is accepted. This shows that there is an effect of guided inquiry learning model on student learning outcomes in the material of electrolyte and non-electrolyte solutions in class X SMA N 1 Batang Onang.

Abstract

Plants that produce fruit are commonly found in Indonesia. This is because some Indonesians grow plants and utilize them as a business. To maintain good quality and quantity, the plants must be well cared for and protected from pests. Pests are organisms that often disturb or damage plants. Generally, pest control is more effective using chemical pesticides and insecticides, but for the environment and health, the use of chemical pesticides can have a negative impact. This occurs due to the prolonged use of chemical pesticides. With this, researchers used five different types of plants as the object of research, namely mango, durian, guava, avocado and orange. The results of using Barangan banana peel (Musa acuminata linn.) showed that Barangan banana peel can be used as a natural pesticide and has an effect on eliminating pests on plants. Therefore, the use of Barangan banana peel as a pesticide can be a solution for the community, and natural pesticides are also good for the environment and human body health.

Abstract

Chemistry is a branch of science that studies various natural phenomena, including the properties, changes in matter, structure, and the energy that accompanies them. The study of chemistry is interconnected with its concepts, making it continuous. The aim of this research is to analyze misconceptions about acid-base materials using a four-tier multiple-choice diagnostic test instrument. The research method used is descriptive qualitative, aiming to analyze student misconceptions. The subjects of this research were class XI students of SMK KIMIA PGRI SERANG CITY. To collect data, observation techniques, four-tier diagnostic tests, interviews, and documentation were used. The results of this research show that 40% of students have misconceptions about acid-base materials, 13% of students understand the concept, and 47% of students don't understand the concept. More students experience misconceptions compared to students who understand the concept. Based on the percentage results, the level of misconceptions for class XI students at SMK KIMIA PGRI Serang City is classified as medium. According to the results of interviews with students, student misconceptions are caused by two factors: internal factors (coming from students) and external factors (coming from learning media such as books and teachers). The factor that causes students' misconceptions is that schools emphasize practice rather than theory, where practice is 60% and theory is 40%.

Abstract

Learning is the process of interaction between teachers and students in educational institutions which aims to achieve the expected results, through educational interactions and the goals of knowledge, attitudes and skills. Teachers play an important role in learning by providing appropriate teaching materials. Current learning still prioritizes the role of the teacher and students' activities in class do not develop independently through discovery and thought processes. Therefore, to overcome this, learning resources that are integrated with information technology and based on student-centered learning models are needed. One model that can be applied to chemistry learning is the experiential learning model. This research is development research using a 4-D model. The research aims to produce an integrated augmented reality worksheet based on experiential learning on electrochemical cells material. The results of the LKPD validation by material and media validators were considered valid in terms of content suitability, experiential learning characteristic aspects, linguistic aspects, presentation aspects, graphic aspects, appearance aspects, and software utilization aspects with percentages of 98.87%, 100% respectively. , 87.5%, 96.87%, 96.87%, 97.22% and 100%. The results of the user response trials, namely teachers and students, were assessed as good with respective percentages of 97.22% and 92.82%

Abstract

Consistent learning is generally based on great curiosity, a drive of need or pressure that makes one inevitably have to recognise new things. The consistency of student learning ultimately requires the main driver commonly referred to as learning motivation. In addition to student learning motivation, careful learning preparation with the application of interesting learning models can be another success factor in education, one of these learning models is the guided inquiry model. The research method used is qualitative with a descriptive approach. The research subject chosen was class XI students in one of the high schools in Semarang City and the sample was all class XI students totalling 36 students consisting of 15 male students and 21 female students, with an age range of 16-18 years. The object of the research is the analysis of guided inquiry learning model on the interest in learning chemistry, especially thermochemistry material. The results showed that 47.2% of students strongly agreed that they had learnt many thermochemistry materials related to daily life. 61.1% of students strongly agree that they have applied the concept of thermochemistry in everyday life, for example by heating water, cooling water, and so on. 30.6% of students disagreed that they had difficulties in learning chemistry materials related to daily life. 91.7% of students answered that learning in the laboratory can maintain their interest in learning, especially in thermochemistry material. Therefore, this guided inquiry learning model is effective to maintain students' learning motivation supported by laboratory facilities.

Abstract

Learning is an effort to provide stimulation, guidance, direction, and encouragement to students so that the learning process occurs which is characterized by changes in student behavior as a result of student interaction with the environment. The observation results explained that the 21st century skills possessed by students were still low. One of the causes of low 21st century skills possessed by students is the lack of active involvement of students in the learning process and the lack of orienting phenomena related to chemical concepts. Therefore, to develop 21st century skills, a learner-centered learning model such as Phenomenon based learning model is needed. This research is a development research using the 4-D model. The research aims to produce LKPD based on phenomenon based learning on colligative properties material. The results of e-module validation by material and media validators are considered very valid in terms of content feasibility, presentation aspects, linguistic aspects, graphical aspects, aspects of phenomenon-based learning characteristics, display aspects, and software utilization aspects with a percentage of 100%, 97.5%, 91.67%, 100%, 82.5%, 94% and 100% respectively. This LKPD is in the very valid range with a score of 94.74%, so this LKPD has been confirmed valid and can be tested.
