Abstract

Kolaborasi dilakukan dengan Perguruan Tinggi mitra yang memiliki jumlah kegiatan-kegiatan penelitian cukup banyak serta berpotensi paten dan jenis HKI lainnya. Permasalahan yang dijumpai di PT mitra yaitu masih rendahnya jenis penelitian berpotensi paten dan masih rendahnya jumlah luaran penelitian dalam bentuk paten dan paten sederhana maupun hak cipta. Dengan demikian kolaborasi dapat dilakukan melalui kegiatan seleksi berbagai penelitian yang sudah dilakukan oleh PT mitra dan analisis penelitian yang berpotensi paten maupun jenis HKI lainnya, serta bimbingan teknis drafting paten. Solusi terhadap permasalahan yang dihadapi PT mitra yaitu melalui pengembangan ide-ide penelitian berbasis sumber daya alam lokal serta pendampingan pemilihan kegiatan-kegiatan penelitian yang berpotensi paten. Selanjutnya solusi terhadap permasalahan PT mitra terkait masih rendahnya jumlah luaran penelitian berupa HKI (paten, paten sederhana, hak cipta, dan sejenisnya), yaitu melalui kegiatan bimbingan teknis penyusunan drafting paten. Kegiatan PPM yang telah dilakukan dapat memberikan pengetahuan tentang penelitian-penelitian bidang green chemistry berbasis sumber daya alam lokal PT mitra yang berpotensi paten dan jenis HKI lainnya sehingga mitra dapat membuat sendiri berbagai penelitian  green chemistry, menambah wawasan bagi mitra tentang cara melakukan penyusunan (drafting) paten berdasarkan penelitian-penelitian yang sudah dilakukan ditunjukkan dengan adanya peningkatan nilai pretes dan postes, dapat menumbuhkan semangat dan kemandirian mahasiswa mitra  untuk membuat produk berbasis sumber daya alam lokal dan berwawasan lingkungan berdasarkan saran yang diberikan, dan meningkatkan kesadaran mitra untuk lebih peduli lingkungan dengan memanfaatkan sumber daya alam lokal menjadi sesuatu yang bermanfaat.

Abstract

Teaching chemistry is a complex subject that requires a certain level of knowledge and skills to understand. Students must overcome this challenge because teaching chemistry involves abstract ideas (atoms, molecules, and electrons) and principles, laws, reaction equations, and mathematical operations. Increasing academic resilience is important in enhancing students' understanding and well-being in learning. This research aimed to test the validity and reliability of students' chemistry academic resilience tests using the Rasch model. Data collection was conducted using Google Forms. Data analysis utilized the Rasch model, assisted by the Winstep application, to reveal various aspects of the assessment. Based on the research findings, a Cronbach's alpha coefficient of 0.78 indicates strong internal consistency. In addition, item reliability reached a significant value of 0.99, while person reliability of 0.78 confirmed the consistency of respondents in providing accurate answers in the assessed categories. Furthermore, the OUTFIT and INFIT MNSQ (persons) have average values of +1.02 and +1.01, respectively (the closer to 1, the better). In contrast, the INFIT and OUTFIT ZSTD values are 0.1 and 0.3, respectively (the closer to 0, the better). The most difficult question is coded ra11 with a logit score of 0.61, and the easiest is coded ra4 with a logit score of -0.05. Therefore, the student academic resilience instrument is an effective measuring tool. In the future, chemistry educators and researchers can benefit from the potential impact of this research on Indonesian education.

Abstract

Higher order thinking skills are an assessment that must be integrated into 2013 Curriculum learning process. The purpose of this study is to investigate the chemistry teacher’s perception about higher order thinking skills assessment. Descriptive qualitative was used in this study. This study implicated 10 chemistry teacher from 10 senior high school in West Kalimantan. Data on chemistry teacher’s perception about higher-order thinking skills assessment were obtained from questionnaire consist of 10 questions. The results showed that most of the chemistry teachers in West Kalimantan already know and implement higher order thinking skills assessment in learning, like final exam and daily test. The HOTS assessment has been implemented by most teachers, but the implementation was not optimal even though in terms of knowledge all teachers already know about the HOTS assessment.

Abstract

The development of a new learning model to increase chemical literacy skills, scientific habits of mind (SHOM), and science process skills (SPS) of chemistry education students is needed to prepare competent chemistry teacher candidates in the future. Theoretical studies have discussed the low chemistry literacy, SHOM, and SPS of students. This research aims to prove the theoretical study data by looking directly at the conditions of chemical literacy, SHOM, and SPS of chemistry education students. The research took place in four stages: measuring and comparing chemical literacy; measuring SHOM; observing SPS during learning activities in the laboratory; and conducting needs analysis for lecturers. The scores obtained from measuring chemical literacy are very worrying. However, there are significant differences in chemical literacy as the years of study increase. Student SHOM is also still in the medium category and needs to be improved. Student SPS is also still relatively low. Furthermore, the lecturers suggested developing a learning model that could develop these three abilities. The model developed must be suitable for adult learning and be able to develop student abilities

Abstract

Critical thinking is one of the 21st-century skills needed. Understanding chemical literacy can encourage students to be able to think more critically. Given the importance of critical thinking and chemical literacy in chemistry learning, there is a need for an assessment instrument that can measure both abilities. Based on this, the integrated assessment instrument was developed to determine the characteristics and feasibility of the integrated assessment instrument that can measure students' critical thinking skills and chemical literacy on reaction rate materials. The sample in this study is 154 students from two high schools in Makassar City. The feasibility and characteristics of the integrated assessment instrument were analyzed using the Rasch model with the Partial Credit Model-1 Logistic Parameter (PCM-1PL) approach. The results of the analysis show that the 10 items developed are valid and have a high reliability value. The integrated assessment instrument has the characteristics of fit with the model, and the difficulty level of the items is classified as good. The results of this study show that the integrated assessment instrument can be used as a good instrument to measure students' critical thinking skills and chemical literacy on reaction rate materials
