Abstract

Penelitian ini bertujuan untuk mengembangkan dan menghasilkan LKPD praktikum berbasis inkuiri terbimbing pembuatan sampo pada topik koloid yang layak digunakan sebagai bahan pembelajaran praktikum untuk peserta didik SMA/MA kelas XII semester 1 kurikulum merdeka. Desain penelitian yang digunakan yaitu Educational Design Research (EDR) yang dilakukan hanya dua tahapan, yaitu tahap pendahuluan dan tahap pengembangan. Penelitian ini dilakukan di salah satu SMA Negeri di Kabupaten Bandung melalui uji coba terbatas yang melibatkan 12 peserta didik kelas XII dan 4 orang observer untuk menguji keterlaksanaan, serta divalidasi oleh 5 orang validator, terdiri atas 2 dosen Pendidikan Kimia dan 3 guru mata pelajaran Kimia untuk menguji kelayakan instrumen. Instrumen penelitian yang digunakan berupa lembar optimasi, lembar uji kelayakan LKPD, lembar observasi keterlaksanaan, rubrik penilaian jawaban LKPD, dan lembar angket respons peserta didik. Hasil optimasi yang dilakukan didapat bahwa komposisi sampo yang optimum yaitu MES sebanyak 6 gram, methylparaben 0,1 gram, glycerin 1 mL, aloevera extract dan tea tree oil 5 tetes, aquadest 100 mL, serta NaCl sebagai pengental 2 gram, karena nilai viskositasnya 3 Pa.s dan berada pada rentang viskositas sampo yang baik menurut SNI. Efek Tyndall yang dihasilkan juga sesuai dengan yang seharusnya, yaitu sinar dihamburkan. Hasil uji kelayakan LKPD praktikum awal dari aspek kesesuaian instruksi, penyajian, tata bahasa, serta tata letak dan perwajahan semua dalam kategori sangat baik. Hasil observasi keterlaksanaan praktikum menggunakan LKPD praktikum berbasis inkuiri terbimbing termasuk kategori sangat baik. Respons peserta didik terhadap LKPD praktikum berbasis inkuiri terbimbing termasuk kategori sangat baik, sehingga dapat disimpulkan bahwa LKPD praktikum yang dikembangkan layak digunakan sebagai bahan pembelajaran praktikum topik koloid di SMA/MA kelas XII. Kata kunci: LKPD, praktikum, inkuiri-terbimbing, koloid, sampo This study aims to develop and produce a guided inquiry-based student worksheet on shampoo formulation in the colloid topic, which is suitable for use as a practical learning material for Grade XII students in senior high schools during the first semester under the Merdeka Curriculum. The research design employed is Educational Design Research (EDR), conducted in two stages: the preliminary stage and the development stage. The study was carried out at a public senior high school in Bandung Regency through a limited trial involving 12 twelfth-grade students and four observers to assess implementation, and validated by five experts, consisting of two Chemistry Education lecturers and three Chemistry subject teachers to evaluate the feasibility of the instruments. The research instruments included optimization sheets, LKPD feasibility test sheets, implementation observation sheets, LKPD answer assessment rubrics, and student response questionnaires. The optimization results indicated that the optimal shampoo composition consists of 6 grams of MES, 0.1 grams of methylparaben, 1 mL of glycerin, 5 drops each of aloe vera extract and tea tree oil, 100 mL of distilled water, and 2 grams of NaCl as the thickening agent. This formulation yielded a viscosity value of 3 Pa·s, which falls within the acceptable range for shampoo viscosity according to Indonesian National Standards (SNI). The Tyndall effect observed was also appropriate, with light being scattered as expected. The initial feasibility test of the LKPD, evaluated in terms of instructional clarity, presentation, language use, layout, and visual design, was rated as excellent. Observations of practicum implementation using the guided inquiry-based LKPD also fell into the excellent category. Student responses to the LKPD were similarly rated as excellent. Therefore, it can be concluded that the developed LKPD is suitable for use as a practicum learning material on the topic of colloids for Grade XII SMA/MA students. Keywords: LKPD, practicum, guided-inquiry, colloid, shampoo
