Summary

Penelitian ini bertujuan untuk menghasilkan bahan ajar kontekstual berbasis kebudayaan pada proses peningkatan kualitas pengolahan rumput laut (sargassum sp.) menjadi senyawa alginat dengan metode asam klorida. Penelitian ini dilatarbelakangi oleh banyaknya siswa yang beranggapan bahwa belajar kimia tidak relevan dengan kehidupan sehari-hari serta kondisi buku ajar yang digunakan oleh guru belum memperhatikan kondisi siswa dan lingkungannya. Metode yang digunakan pada penelitian ini yaitu Development Research tipe satu Design, Development, dan Evaluation dengan model pengembangan bahan ajar 4D (define, design, develop, dan disseminate). Parameter optimum diperoleh melalui kajian literatur dikarenakan kondisi COVID-19 sehingga percobaan di laboratorium tidak dapat dilakukan. Berdasarkan kajian literatur penggunaan larutan HCl yang menghasilkan persentase alginat yang banyak yaitu dengan konsentrasi larutan HCl 0,1 M dengan dua kali perlakuan perendaman. Konsep kimia dan kompetensi dasar berdasarkan hasil karakterisasi adalah menghubungkan faktor adanya ikatan hidrogen dengan hasil senyawa alginat yang diperoleh (KD 3.7 Kelas X), menerapkan faktor luas permukaan dan suhu yang mempengaruhi laju reaksi (KD 3.6 Kelas XI), menerapkan faktor yang mempengaruhi pergeseran kesetimbangan kimia (KD 3.9 Kelas XI), dan menganalisis struktur, tata nama, sifat dan penggolongan makromolekul (KD 3.11 Kelas XII). Hasil keterbacaan bahan ajar yang diperoleh sebesar 68,86%. Kata Kunci: alginat, bahan ajar kontekstual, kebudayaan, pengolahan rumput laut This study aims to produce contextual teaching materials based on culture in the process of improving the quality of processing seaweed (sargassum sp.) Into alginate compounds using the hydrochloric acid method. This research is motivated by the large number of students who think that learning chemistry is not relevant to everyday life and the condition of the textbooks used by the teacher has not paid attention to the conditions of students and their environment. The method used in this research is Development Research type one Design, Development, and Evaluation with the 4D teaching materials development model (define, design, develop, and disseminate). The optimum parameters were obtained through a literature review due to the COVID-19 condition so that laboratory experiments could not be carried out. Based on the literature review, the use of HCl solution which produces a large percentage of alginate, namely with a concentration of 0.1 M HCl with two immersion treatments. The results of the characteristics of the chemical concept and basic competence consist of connecting the factor of the presence of hydrogen bonds with the results of the alginate compound obtained (KD 3.7 Class X), applying the surface area and temperature factors that affect the rate of reaction (KD 3.6 Class XI), applying the factors that affect the shift chemical equilibrium (KD 3.9 Class XI), and analyze the structure, nomenclature, properties and classification of macromolecules (KD 3.11 Class XII). The percentage of teaching material legibility test obtained was 68.86%, including the high category. Keywords: alginate, contextual teaching materials, culture, seaweed processing
