Abstract

PISA and TIMSS results have been used as a basis for educational reform, but unfortunately, teachers’ understanding of PISA and TIMSS tests is rarely investigated. We evaluated 149 sophomore preservice chemistry teachers’ achievement in TIMSS and PISA-like test. As a way to reflect on TIMSS and PISA results, we compared preservice chemistry teachers’ achievement to PISA and TIMSS results for Indonesia and the international students. Results suggested that, to a certain degree, preservice chemistry teachers have a better chemical literacy than Indonesian students and a somewhat similar chemical literacy with international students.

Abstract

Ethnochemistry is a chemical applied by certain cultural groups. This study aims to obtain information and descriptions of what ethnochemistry practiced by the Acehnese tribe in East Aceh and what potential of ethnochemistry can be developed in chemistry lectures. This research was carried out in East Aceh Regency and Langsa City. The research subjects consisted of teachers, lecturers, administrators of the Majelis Adat Aceh (MAA) and community leaders from East Aceh who were well acquainted with ethnochemical practices in the community. This research is a qualitative research model with ethnographic methods. The stages of the study included the theoretical study stage, namely literacy studies on ethnography of Acehnese tribal communities and applied chemistry and the stages of empirical study or data collection to inventory the ethnochemical knowledge practiced by the Acehnese people. Data collection was carried out using observation techniques, documentary studies, and interviews with research instruments include observation sheets, documentation, and interview guidelines. Data analysis techniques in research use a qualitative approach. Data obtained from interviews, observations, and documentation are analyzed simultaneously by first sorting out similar data (categorization) and then doing data reduction, presentation, and conclusions as well as verification. The results of the study showed that the ethnochemical knowledge of the tribes of Aceh in East Aceh that could be developed in chemistry lectures included the analysis of chemical studies on: natural ingredients used as medicines; natural ingredients used as food additives; natural ingredients used as beauty and cleaning tools and materials; appropriate technology; and processing typical Acehnese food.  ABSTRAKEtnokimia adalah kimia yang diterapkan oleh kelompok budaya tertentu. Penelitian ini bertujuan untuk memperoleh informasi dan deskripsi tentang etnokimia apa saja yang dipraktikkan suku Aceh di Aceh Timur dan potensi apa saja dari etnokimia tersebut yang dapat dikembangkan dalam perkuliahan kimia. Penelitian ini dilaksanakan di Kabupaten Aceh Timur dan Kota Langsa. Subjek penelitian terdiri dari guru, dosen, pengurus Majelis Adat Aceh (MAA) serta tokoh masyarakat asal Aceh Timur yang mengenal betul praktik etnokimia di masyarakat. Penelitian ini merupakan model penelitian kualitatif dengan metode etnografi. Tahapan penelitian meliputi tahap kajian teori yaitu studi literasi tentang etnografi masyarakat suku Aceh dan terapan ilmu kimia serta tahap kajian empirik atau pengumpulan data untuk menginventarisasi pengetahuan etnokimia yang dipraktikkan masyarakat Aceh. Pengumpulan data dilakukan dengan menggunakan teknik pengamatan, studi dokumenter, dan wawancara dengan instrumen penelitian meliputi lembar observasi, dokumentasi dan pedoman wawancara. Teknik analisis data dalam penelitian menggunakan pendekatan kualitatif. Data yang diperoleh dari wawancara, pengamatan, dan dokumentasi dilakukan analisis secara simultan dengan terlebih dahulu melakukan pemilahan data yang sejenis (kategorisasi) selanjutnya dilakukan reduksi data, penyajian, dan kesimpulan serta verifikasi. Hasil penelitian menunjukkan pengetahuan etnokimia suku Aceh di Aceh Timur yang dapat dikembangkan dalam perkuliahan kimia meliputi analisis kajian kimia tentang: bahan alam yang dijadikan obat-obatan; bahan alam yang dijadikan zat aditif makanan; bahan alam yang dijadikan alat dan bahan kecantikan serta pembersih; teknologi tepat guna; dan pengolahan makanan khas Aceh. Keywords: Aceh, ethnochemistry, inventory, local wisdom, etnokimia, inventarisasi, kearifan lokal.

Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan minat belajar setelah diterapkannya strategi question student have berbantuan media kartu. Metode dalam penelitian ini adalah kuasi eksperimen dengan desain one group pretest-posttest. Populasi dalam penelitian ini adalah seluruh siswa kelas XI IPA di SMA Negeri 5 Langsa tahun pelajaran 2018/2019 yang berjumlah 110 siswa. Pengambilan sampel dilakukan dengan teknik simple random sampling sehingga didapatkan kelas XI IPA 3. Data dianalisis menggunakan Uji t Paired T-Test. Berdasarkan dari data yang dikumpulkan oleh peneliti diperoleh bahwa terdapat peningkatan minat belajar kimia siswa pada materi kelarutan dan hasil kali kelarutan (Ksp) setelah menggunakan penerapan strategi question student have berbantuan media kartu. Hal ini ditandai dengan menggunakan uji statistik parametrik yaitu thitung ≥ ttabel (8,50 ≥ 1,67) sehingga H0 ditolak dan Ha diterima, maka dapat disimpulkan bahwa terdapat peningkatan minat belajar kimia siswa pada penerapan strategi question student have berbantuan media kartu secara signifikan. Harapan peneliti untuk peneliti selanjutnya bisa mengembangkan penelitian ini menjadi lebih baik dan juga mereka bisa mendukung hasil penelitian ini.

Abstract

The community service that has been carried out aims to improve the economy of the Kuala Leuge Pereulak village community in East Aceh through processing local community catches with effective and appropriate fish drying. The method of implementing the service carried out is through socialization and education regarding the effective use of marine products through the sale of dried fish or salted fish using good and effective drying. The outcome of the program that has been carried out has a positive impact on the community in Kuala Leuge village, which can improve the community's economy through training from activities carried out by the community, making it easier to dry fish that will be marketed.

Abstract

This research is intended to synthesize Sn-ZIF-8 with an environmentally friendly hydrothermal method by exploring the potential of the utilization of aqueous solvents as the main solvent. Sn-ZIF-8 material has been successfully synthesized with water solvent at room temperature and has been characterized using XRD, FTIR, and SEM instrumentation to determine the extent of synthesis success. In this study, the use of Sn doping varied from 5, 10, and 15%, while MeIM, NH4OH, and water precursors were kept constant. Instrumentation observations showed the XRD patterns of Sn-ZIF-8 compounds for percentages of 5, 10, and 15% of Sn2+ displayed specific peaks of ZIF-8 at 2 = 7.24, 10.28, 12.62, 16.34, and 17.92. Meanwhile, the FTIR spectra of all synthesized solids presented the same functional group absorption peaks as the simulated ZIF-8 solids. SEM observation revealed a regular crystal shape of Sn-ZIF-8 without any contaminant on its surface. The characterization results show no change in the basic structure and the addition of other structures from ZIF-8. The implication of this finding can be utilized as a reference source for synthesizing inorganic materials using eco-friendly stages without affecting the synthesized product
