Perkembangan IPTEK di abad 21 menuntut siswa memiliki kemampuan dalam berpikir kreatif. Siswa diharapkan mampu menyelesaikan masalah dengan kreativitasnya. Hasil observasi menunjukkan belum ada instrumen tes yang dapat mengukur kemampuan berpikir kreatif siswa. Penelitian ini bertujuan untuk mengetahui keefektifan instrumen yang dikembangkan untuk mengukur kemampuan berpikir kreatif. Penelitian ini merupakan penelitian pengembangan yang mengadopsi model 4-D, namun dilakukan sampai tahap 3-D yaitu, define, design, dan develop. Subjek penelitian adalah siswa kelas XI SMA N 1 Banjarnegara. Analisis data dilakukan secara kualitatif dan kuantitatif. Reliabilitas dihitung menggunakan rumus Alpha Cronbach. Validitas instrumen divalidasi oleh ahli. Instrumen tes dinyatakan efektif dilihat dari analisis kemampuan berpikir kreatif siswa dan ketercapaian terhadap indikator. Aspek atau indikator kemampuan berpikir kreatif yang dapat terukur menggunakan instrumen tes sebesar 68,666%. Kesimpulannya instrumen tes yang dikembangkan efektif untuk mengukur kemampuan berpikir kreatif siswa.

During online learning, students are generally asked to study practicum procedures that have been provided by the lecturer, then they are given raw data from practicum results in the previous semester for analysis and preparation of practicum reports. Another method used is to provide demonstration videos or use digital applications such as virtual labs. In general, students can attend lectures smoothly and well, but many also say that this method is boring because there is almost no difference with theoretical classes. The object of the research is second semester chemistry students, which consists of 1 class of chemistry program and 1 class of chemistry education program. The research begins with a pretest, then students carry out the planned learning, then ends with a posttest and filling out a questionnaire. The project in the do lab at home practicum is specified to titrate a solution of vinegar with a solution of baking soda or vice versa. Each student prepares a buffer solution with various pH according to the instructions of sub-project 1, makes an acid-base indicator solution from natural materials according to the instructions of sub-project 3, and determines the RGB ratio of a buffer solution that has been given a natural acid-base indicator using the instructions of the sub-project. In quantity, all students upload practicum videos, with a duration ranging from 8-15 minutes. Based on the results of the practicum videos uploaded by students, the first creativity that can be seen immediately is the composition of video editing, such as sound quality, image quality, and the addition of information in the video. In this study, in general, it can be said that students are in the development stage for the fluency-brainstorming indicator. Just like fluency indicators, flexibility indicators are also generally still in the developing stage, they still need help in taking new perspectives. Making videos, although not the main product, can train students' skills, including creative thinking. In detail, risk taking indicators are further divided into 2, namely risk taking-1 and risk taking-2. Most of the students are at the developing level for the risk taking-1 indicator.

The community service activity's background stems from observations, interviews, and data collected during Field Experience Practice and Teacher Professional Education mentoring activities for prospective science and chemistry education teachers. It was identified that candidates need enhancement in developing chemistry teaching modules oriented toward the Pancasila Student Profiles (PSP). The activity aims to address this issue by providing competency training in preparing chemistry teaching modules oriented to Pancasila Student Profiles using the GPT Chat application. The target audience for the activity includes chemistry teachers who are members of MGMP Semarang and Kudus, with approximately 25 participants. The activities include training and mentoring through In-House Training, assistance in creating chemistry teaching modules oriented towards Pancasila Student Profiles, and assessment of the developed teaching modules. Based on the data from the community service activity implementation, the following conclusions can be drawn: (1) training participants have increased their competency in compiling chemistry teaching modules oriented towards strengthening the profile of Pancasila students, (2) chemistry teaching modules oriented towards strengthening the profile of Pancasila students have been produced with good and excellent quality, (3) the response of the target audience from the community service activity indicates a positive impact.

Household waste, which is mostly in the form of food waste such as vegetables and fruits, is a source of waste accumulation. More than fifty percent of the waste accumulation in Banyudono village, Boyolali, Central Java is household waste. The accumulation of garbage causes environmental pollution problems that can result in a decrease in the quality of life of residents. Garbage accumulation occurs because residents only throw it into the surrounding environment or rely on garbage transport trucks to be disposed of in landfills. This is due to the lack of knowledge among of residents (the participant of the service activities) in waste processing. Proper waste management not only makes the environment clean and healthy, but also improves the community's economy through the creation of value-selling products. To overcome the partner's problem, namely the accumulation of waste, the service team provides solutions according to the partner's needs, namely the transfer of science and technology (IPTEK) to process household waste (organic) into organic fertilizer (compost). The transfer of science and technology to Banyudono Village residents take place in July 2023 and participants were given assistance to implement the science and technology to treat waste independently. The results were monitored 3 months later according to the known composting method. Composting is done using EM4 bioactivator so that the results can be harvested within 3 months of composting. Compost quality analysis is carried out after the compost is physical and chemical mature which confirmed by checking pH and levels of nitrogen, phosphorus, and potassium. The obtained compost was blackish with a smell like earth, and has a fine texture. The compost had a pH of 6.9 and the nitrogen, phosphorus, and potassium levels meets SNI standards. Through this activity, participants able to processing household waste independently.
