Miskonsepsi seringkali terjadi pada mata pelajaran yang bersifat abstrak. Beberapa materi yang terdapat pada mata pelajaran Kimia bersifat abstrak, seperti materi bilangan kuantum dan konfigurasi elektron. Salah satu cara yang dilakukan untuk mengetahui tingkat miskonsepsi siswa terhadap materi perlu dilakukan penelitian dengan menggunakan tes diagnostik three tier multiple choice (TTMC). Tes diagnostic TTMC pada materi bilangan kuantum dan konfigurasi elektron belum banyak dikembangkan, sehingga pengembangan tes diagnostik TTMC pada materi bilangan kuantum dan konfigurasi elektron perlu disusun terlebih dahulu. Pengembangan instrumen soal tes diagnostic TTMC pada penelitian ini dilakukan melalui tiga tahap, yaitu pengembangan butir soal, validasi butir soal, dan ujicoba butir soal kepada peserta didik. Hasil penelitian diperoleh 21 butir soal valid dan reliabel dengan nilai CVR 1.00. Miskonsepsi tertinggi pada materi bilangan kuantum dan konfigurasi elektron ditemukan pada sub konsep menentukan seperangkat bilangan kuantum dari suatu orbital. Perbedaan miskonsepsi tertinggi antara kelas X IPA dan X imersi terdapat pada sub konsep menentukan seperangkat bilangan kuantum dari elektron pada tingkat energi tertinggi.

This study was conducted to measure students' conceptual understanding of chemical bonds. The test through an online form includes a two-level test—a total of 50 students who have studied chemical bonds as research subjects. The method used is quantitative through analysis with the dichotomous Rasch model. A total of seven sub-concepts of chemical bonds have been tested on students through a two-level test, namely questions, and reasons. The questions given were declared valid and reliable according to the Rasch model. The concept that is considered the most difficult for students is the description of orbitals and molecular hybridization

The purpose of this research is to design a four-tier diagnostic test instrument on electron configurations and quantum numbers that can be used to analyze misconceptions. The four-level diagnostic test instrument is an assessment instrument that functions to assess students' conceptual comprehension in understanding a subject matter. The four tier test has four levels, namely knowledge questions, confidence questions in completing questions, reasons for answering questions, and confidence in giving reasons. This study uses a descriptive qualitative method with the stages of analyzing the problem, collecting data, product design, validating the design, and conducting instrument trials. The results showed that the designed diagnostic instruments were feasible and reliable. Instrument test results indicate that indicator a) determines the magnitude of the four quantum numbers (n,ℓ,mℓ, ms) in an orbital; b) identify the characteristics and functions of the azimuth quantum number (ℓ); c) determine the spin magnetic quantum number (ms) of the electron in the orbital; and d) determine the spin magnetic quantum number (ms) of a single electron in an orbital, which is the most misunderstood.

The purpose of this study was to determine the physical and chemical quality of the groundwater in the Jerakah flats area and to determine the feasibility of the water as drinking water. This research was physically carried out by analyzing groundwater samples from the rented flats of the Jerakah sub-district based on the physical parameters of the air, including taste, color, smell, temperature, turbidity, and dissolved solids (TDS) as well as chemical parameters consisting of the degree of acidity. (pH), Nitrate Content (NO3-), Nitrite (NO2-), Hardness (CaCO3), Iron (Fe), Lead (Pb), Manganese (Mn), Zinc (Zn), Sulfate (SO42-), Cadmium (Cd), and Chromium (Cr). The results showed that the groundwater in the Jerakah flats had a normal pH, colorless, tasteless, odorless, low turbidity, and high dissolved solids (TDS). The levels of iron (Fe), manganese (Mn), chromium (Cr), zinc (Zn), cadmium (Cd), lead (Pb), and hardness are below the maximum hygienic sanitary limits. Manganese (Mn), Cadmium (Mn), Lead (Pb) levels exceed the maximum limit for drinking water. The groundwater in the Jerakah flat is suitable for use for hygienic sanitation, such as bathing and washing, but not suitable for drinking.

Kimia merupakan ilmu yang bersifat abstrak dan cukup sulit bagi siswa untuk memahaminya mengingat adanya tiga representasi yang harus dikuasai. Kimia bersifat hirarki, artinya suatu konsep berkesinambungan dengan konsep lainnya. Larutan penyangga merupakan salah satu materi kimia yang sulit dipahami dan siswa sering mengalami miskonsepsi. Perlu ditinjau ulang untuk mengetahui seberapa besar kesalahpahaman siswa setelah proses pembelajaran dan setelah pembelajaran, sehingga dengan adanya penelitian mengidentifikasi mengenai miskonsepsi dapat mengukur sejauh mana tingkat miskonsepsi siswa dan dapat menjadi masukan bagi guru. Tujuan penelitian ini untuk memberikan informasi mengenai miskonsepsi dan penyebab terjadinya miskonsepsi pada materi larutan penyangga. Jenis penelitian ini menggunakan pendekatan kuantitatif deskriptif. Subjek pada penelitian ini sebanyak 69 siswa kelas XII SMA Negeri 11 Semarang. Instrumen yang digunakan berupa tes diagnostik five-tier. Tes dilakukan dengan menggunakan media Googleform. Berdasarkan hasil analisis diketahui bahwa persentase miskonsepsi siswa sebesar 41,06%, tidak paham konsep 33,58%, paham konsep 8,58% dan eror 16,79%. Penyebab miskonsepsi ada beberapa, diantaranya pemikiran pribadi 29,71%, guru 0,24%, buku 1,57%, teman 5,19%, dan internet 3,86%.

Ideally, students should have scientific literacy skills to understand and apply chemical concepts in real life. Students' scientific literacy is still low, especially in understanding abstract chemical equilibrium material. This study aims to analyze the effectiveness of the Problem-Based Learning-Group Investigation (PBL-GI) model in improving students' scientific literacy in chemical equilibrium material. This study used a quasi-experimental method with a nonequivalent control group design. The sample was selected using the cluster random sampling technique, and data were collected through test and non-test techniques. The results of the study showed that the PBL-GI model was effective in improving students' scientific literacy, as evidenced by the results of the hypothesis test (tcount = 4.824> ttable = 1.669), and the N-gain value of the experimental class (0.6487) was higher than that of the control class (0.5064). Thus, Ha is accepted, namely, the PBL-GI model effectively improves students' scientific literacy skills. The results of this study are expected to encourage teachers to design problem-based learning relevant to real life.
