Abstract

Penelitian ini bertujuan untuk optimasi Atomic Absorption Spectrophotometer (AAS) di Laboratorium Kimia FMIPA UNNES untuk menguji logam tembaga (Cu) dalam limbah cair laboratorium. Penelitian ini menggunakan metode eksperimen. Metode penelitian ini meliputi: (1) Preparasi contoh uji; (2) Optimasi kondisi analisis unsur tembaga dengan variasi: laju udara, panjang gelombang, dan arus lampu; (3) Penentuan sensitivitas atau kepekaan serta presisi alat AAS; (4) Penentuan daerah kerja AAS; (5) Penentuan LoD dan LoQ. Pengujian logam Cu di Laboratorium Kimia FMIPA UNNES telah mengacu pada SNI-6989-84:2019, namun masih belum optimal karena terdapat nilai hasil uji untuk logam Cu yang belum sesuai. Hal ini dikarenakan adanya gangguan matriks yang dapat memperkecil ataupun meningkatkan jumlah absorbansi, sehingga menyebabkan hasil pengujian kurang valid. Penelitian ini memperoleh kondisi optimum penggunaan AAS yaitu menggunakan perbandingan laju udara dan asetilen sebesar 10:2 (L/menit), pengujian logam Cu pada panjang gelombang 324,8 nm, dan arus lampu 15 mA menghasilkan absorbansi terbesar dalam pengukuran logam Cu.

Abstract

Pendidikan memegang peranan sentral dalam mengembangkan sumber daya manusia yang unggul dan berdaya saing, salah satu caranya adalah dengan meningkatkan kualitas calon pendidik yang akan berperan langsung dalam proses pembelajaran. Untuk mencapai SDGs 4: Pendidikan Bermutu, dibutuhkan pendidik yang memiliki keterampilan merancang perangkat pembelajaran yang memenuhi standar nasional dan kebutuhan peserta didik yang dapat dilakukan melalui pendekatan studi kurikulum. Penelitian ini bertujuan untuk meningkatkan keterampilan siswa calon guru dalam merancang perangkat pembelajaran Program Semester (Prosem), Alur Sasaran Pembelajaran (ATP), dan Modul Ajar sebagai bentuk implementasi SDGs 4: Pendidikan Bermutu melalui studi kurikulum. Metode penelitian yang digunakan adalah metode deskriptif kuantitatif dengan pendekatan studi kasus. Subjek penelitian adalah 25 mahasiswa semester empat Program Studi Pendidikan Kimia Universitas Negeri Semarang. Pengumpulan data dilakukan melalui lembar penilaian sejawat dan angket tanggapan. Hasil penelitian menunjukkan adanya peningkatan keterampilan siswa calon guru dalam merancang perangkat pembelajaran sebelum dan sesudah studi kurikulum sebesar 32% untuk program semester, 28% untuk ATP, dan 21% untuk modul terbuka. Persentase tanggapan siswa mengenai persepsi mereka terhadap kurikulum pembelajaran adalah 82,63%, yang dikategorikan sangat baik. Studi ini menyimpulkan bahwa pembelajaran yang efektif dalam meningkatkan keterampilan calon guru dalam merancang perangkat pembelajaran, sehingga mewujudkan pendidikan yang berkualitas (SDGs 4).

Abstract

Various studies have shown that applying the guided discovery learning model can increase students' interest in learning, which ultimately leads to better learning outcomes. This is especially important for difficult subjects or topics, such as basic chemistry laws. Based on observations at SMA Kristen YSKI, the researcher found indications of low student interest in chemistry. This study aims to analyze students' learning interest and learning outcomes as well as the relationship between the two. The research, using an explanatory sequential design, was conducted on Grade XI Fearless and Genuine students. Data on learning interest was collected through a psychometric scale questionnaire, while learning outcomes were measured through a test, followed by qualitative data collection through interviews. The data was then analyzed using descriptive statistics and correlation analysis between learning interest and learning outcomes. The results of the study provide data on students' interest in chemistry and their learning outcomes in basic chemistry laws, including distribution and central tendency analysis. Interestingly, some students with high learning interest scored low on the test, which was an unexpected result. Interviews were conducted with these students to understand the reasons behind this outcome. Some of the reasons mentioned included difficulty adjusting after the semester break, a tight schedule of tests and extracurricular activities, and a mismatch with the applied learning model, which led to less effective learning.

Abstract

Chemistry education in the 21st century demands the development of chemical literacy that not only masters theoretical concepts, but also relates science to real-life contexts and scientific thinking skills. This study aims to develop a valid and reliable ethnoscience-based chemical literacy test instrument and STEM approach on thermochemical material for high school students. The development model used is 4D (Define, Design, Develop, Disseminate). The results of observations and interviews showed the need for instruments that integrate the local cultural context, especially the practice of making pottery in Klaten, with the concept of thermochemistry. Expert validation resulted in an Aiken's V value of 0.92 (high category), and the reliability test showed a value of 0.71 (good). Rasch analysis confirmed the validity of the items and the varying difficulty of the questions. This instrument is expected to improve students' chemical literacy in a contextual and meaningful way and encourage critical thinking skills
