S KIM 1002505 Abstract
ABSTRAK
Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Siswa Praktikum
berdasarkan model inkuiri terbimbing serta untuk memperoleh informasi
mengenai kelayakan LKS yang dikembangkan. Langkah penelitian yang
dilakukan yaitu studi pendahuluan terdiri atas studi kepustakaan, survei lapangan,
penyusunan produk awal serta pengembangan model berupa uji coba terbatas.
Sumber data penelitian ini adalah bahan ajar praktikum yang digunakan oleh
siswa SMA kelas XII di Kota Bandung, guru kimia SMA, serta dosen Departemen
Kimia Universitas Pendidikan Indonesia. Instrumen penelitian yang digunakan
adalah lembar analisis LKS praktikum, pedoman wawancara, lembar observasi
keterlaksanaan praktikum, lembar penilaian LKS oleh guru dan dosen, pedoman
penilaian jawaban siswa terhadap tugas LKS, serta angket respon siswa. Hasil
penelitian menunjukkan bahwa dari 10 bahan ajar yang dikaji ada 7 bahan ajar
yang menyediakan LKS praktikum pada topik sifat koagulasi dengan karakteristik
berupa cookbook. LKS praktikum yang dikembangkan berisi percobaan koagulasi
melalui pembuatan tahu dengan kondisi optimum suhu air yang ditambahkan pada
suhu 90 oC, volume asam asetat yang digunakan sebanyak 13 mL, serta waktu
penggumpalan selama 5 menit. Kelayakan LKS praktikum yang dikembangkan
berdasarkan keterlaksanaan tahap-tahap inkuiri siswa (100%), jawaban siswa
(93,53%), penilaian guru terhadap kelayakan LKS praktikum yang dikembangkan
berdasarkan aspek kesesuaian konsep (97,5%), aspek kesesuaian tata bahasa
(83,33%), serta respon siswa terhadap penggunaan LKS praktikum yang
dikembangkan (81,84%) termasuk dalam kategori sangat baik.
Kata kunci: LKS praktikum, inkuiri terbimbing, sifat koloid, koagulasi,
pembuatan tahu

ABSTRACT
This research aims to develop Student Laboratory Worksheet based on guided
inquiry model as well as to obtain information about properness the developed
laboratory worksheet. Research steps include preliminary research that consists of
literature study, area survey, prototype model and further development based on
limited trial. Source of the research data based on laboratory teaching module that
are widely used by grade XII senior high school students, chemistry teachers and
lecturers in Chemistry Department at Education University of Indonesia. This
research use instrument such as analysis reports of Student Laboratory Worksheet,
interview guidelines, working laboratory observation sheets, scoring sheets of
Student Laboratory Worksheet done by teachers and lecturers, guidelines in scoring
student answer for Student Laboratory Worksheet as well as student questionnaire
responses. The result of this research is within 10 teaching materials that were
reviewed, 7 out of 10 were showing coagulation behavioral topic with cookbook
characteristic in the Student Laboratory Worksheet. The developed Student
Laboratory Worksheet in coagulation experimentation of making tofu process
includes using optimum water temperature condition that was added at 90˚C, 13
mL of acetic acid and coagulation time for 5 minutes. The properness of Student
Laboratory Worksheets developed based on student inquiry is 100% whereas when
it is based on student answer, the score is 93.53%. The score given by teachers on
the worksheets that were developed on concept compatibility is 97.5%, whereas on
language compatibility, the score is at 83.33%, and student response on using
Student Laboratory Worksheets that were developed is at 81.84% which is highly
satisfactory.
Keywords: Student Laboratory Worksheet, guided inquiry, colloid characteristic,
coagulation, tofu production process
