Abstract

Misconception is an event of a wrong concept received by students after following a learning process, the concept received is not in accordance with existing scientific studies. This study aims to identify students' misconceptions on the colligative properties of the solution and the factors that cause misconceptions. This type of research is descriptive quantitative. The instrument used is a four-tier multiple choice diagnostic test. This study involved 34 students of class XII MIA at MA Khulafaur Rasyidin Sungai Raya. The results showed that the level of misconceptions of students had an average percentage of 34% with a moderate misconception category, where a total of 65% students experienced misconceptions in the sub-topic of vapor pressure depression, 26,30% students experienced misconceptions in the sub-topic of freezing point depression,  33,30% students experienced misconceptions in the sub-topic of boiling point elevation, and  26% students experienced misconceptions in the sub-topic of osmotic pressure. Based on the results of the interview, the factors causing misconceptions in this study consist of internal and external factors. Internal factors come from students, that are students provide concept ideas spontaneously based on their understanding without being investigated first, students provide incorrect reasoning, students are confused in connecting one concept with another, lack of interest and ability of students in learning chemistry. External factors come from the context and teaching methods, where one of the learners' discussion partners has misconceptions, the teacher is more dominant in providing chemical explanations in mathematical form, and limited experiments. Those misconceptions can be reduced by presenting the topic in an interesting way, using an experiment, or using multiple representations approach.

Abstract

The competence of educators in the use of technology in learning today is still not enough to answer the challenges of 21st-century learning. For this reason, it is necessary to assist increased science educators with TPACK-based learning tools. The results of a survey of educators found that educators still hadn't applied technology in their learning so in preparing learning tools they were still not skilled.  This activity aims to provide knowledge and skills to educators regarding the preparation of TPACK-based learning tools, describe the understanding of science educators on the role and use of technology, describe the ability of educators to design TPACK-based learning tools, and determine the response of educators to the activities carried out. The socialization and mentoring were using discussion and group work methods. The Activity was attended by 18 science teachers in Sintang Regency. The results of the mentoring show that this assistance is very helpful for educators in understanding TPACK and the knowledge of teachers about TPACK and the preparation of TPACK-based learning tools is increasing.

Abstract

The era of globalization requires students as the nation's next generation to have 21st century skills. However, most students have not received or been trained in 21st century skills while in college. Learning with a constructivist approach with the case method model and team-based project is one strategy to solve this problem, but most of the lecturers in the PMIPA FKIP Untan department have not been able to distinguish and apply the two learning models. This is due to the low understanding of educators related to the case method and team-based project learning models. The aim of this workshop is to improve lecturers' understanding and skills in developing learning tools using the case method and team-based projects. This workshop begins with a presentation of material on the case method and team-based project learning tools using the lecture method and continues with a review of the RPS that has been prepared by the lecturer. All activities are carried out online. The results of the workshop were that 96.5% of the lecturers had understood the RPS using the case method and 93% of the team-based project. As many as 65.5% of lecturers stated that this activity was very helpful in preparing lesson plans with the case method and team-based projects. Meanwhile, 96% of participants wanted to do similar activities again. This indicates that this workshop has provided understanding and assisted participants in preparing lesson plans using the Case Method and Team Based Project. The results of this workshop have motivated lecturers to produce learning tools, especially better lesson plans.

Abstract

The implementation of technology in learning activities, especially evaluation and learning media, has not been implemented optimally. The fact that educators do not assess all of these aspects and are still fixated on conventional assessments and innovative media and assessment designs as demanded by the 21st century, which is rarely done. For this reason, to improve the skills of educators, especially science educators who are members of the Mempawah Regency MGMP, training in making assessments and TPACK-based learning media is needed. The purpose of this activity is to improve the ability of educators to make TPACK-based assessments and media in learning and to describe educators' responses to the socialization activities carried out. This training uses a qualitative descriptive method and the material exposure through practice, discussion, and presentation. The results of the training are known to be very helpful for educators to develop assessments and learning media that are interesting, innovative, and effective for students by utilizing technology that is easily accessible to anyone and increasing the knowledge and creativity of educators regarding the implementation of technology in preparing assessments and learning media specifically for science subjects.

Abstract

Litsea firma (Blume) Hook. f. has long been utilized as a traditional medicine plant. This research aims to analyze the quality of L. firma (Blume) Hook F essential oils extracted from its leaves, stems, and roots and to evaluate their anti-termite activity. The essential oils were obtained using the steam-water distillation method for 8 hours in triplicate. The quality of the essential oils was determined by their yield, specific gravity, refractive index, and optical rotation angle, which was compared with the previously reported quality data of L. cubeba essential oil. The results showed that all L. firma essential oils possessed a transparent colour, a distinctive aroma, and a bitter taste. The quality assessment revealed that essential oil yields ranged from 0.16% - 2.42%. The specific gravity of leaves essential oil was 0.83. Furthermore, the refractive index ratio ranged from 1.43 to 1.44, and the optical rotation angle varied between +15.3° to +16.8°. Phytochemical analysis revealed the presence of terpenes in L. firma essential oil. Essential oil of L. firma leaves exhibited a pronounced anti-termite activity with a percentage mortality of 100% and paper weight loss of 11.6 %. Thus, L. firma essential oils, particularly from leaves, had promising potential for natural termite control.

Abstract

In science learning activities,learning objectives can be achieved if students are active in learning activities.The form of student activity in learning can be seen from the skills of asking questions and finding (lookingfor) answers that originate from their curiosity.Therefore, teaching materials are needed that can make students active, as a tool in the learning process and can be used as a learning resource. One of them is the Student Worksheet (LKPD). However, the LKPD circulating in school semphasizes more on questions and filling inquestions without explaining how the process of obtaining answers to these questions. In addition, the LKPD used looks monotonous, unattractive, and difficult to understand so that students are less motivated to study and understand the contents of the LKPD. Therefore, it is necessary to develop LKPD which aims to find out the stages in making guided inquiry based LKPD to determine the feasibility of LKPD to be used as teaching materials, and to determine student responses to guided inquiry-based LKPD on elements,compounds and mixtures in class VIISMP. The form of researchuse disresearch and development (R&D) which adopts the 4D development model (Define,design,develop,dessiminate) by Thiagarajan.
