PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) PRAKTIKUM BERBASIS PROJECT BASED LEARNING (PjBL) PADA MATERI KOLOID PENJERNIHAN AIR DENGAN KOAGULAN ALAMI
Penelitian ini bertujuan untuk menghasilkan Lembar Kerja Peserta Didik (LKPD) praktikum berbasis Project Based Learning (PjBL) percobaan penjernihan air dengan koagulan alami pada topik koloid untuk pembelajaran kimia kelas XI IPA SMA/MA. Partisipan dalam penelitian ini adalah 12 orang siswa kelas XII di salah satu SMA negeri di Kota Bandung. Metode penelitian yang digunakan adalah educational design research, namun dalam penelitian ini hanya sampai tahap pengembangan. Hasil optimasi prosedur praktikum diperoleh biji kelor dengan massa 0,3 gram sebagai koagulan yang paling efektif diantara koagulan alami lainnya seperti biji pepaya, biji asam jawa, daun kelor segar dan daun kelor kering, variasi waktu optimal untuk menjernihkan air selama 12 jam, dan tidak terjadi perubahan pH baik sebelum maupun sesudah proses koagulasi. Lembar Kerja Peserta Didik (LKPD) praktikum yang telah disusun diuji kelayakannya oleh validator yang terdiri dari 3 orang dosen Pendidikan Kimia UPI dan 2 orang guru kimia SMA. Hasil uji kelayakan terhadap kesesuaian komponen dalam LKPD dengan tahapan PjBL, kesesuaian konsep, tata bahasa, serta tata letak dan perwajahan termasuk dalam kategori sangat baik. Hasil respon siswa terhadap LKPD praktikum yang dikembangkan termasuk dalam kategori sangat baik begitupun hasil respon siswa terhadap kegiatan praktikum menggunakan LKPD praktikum yang dikembangkan juga termasuk kategori sangat baik, sehingga LKPD praktikum berbasis PjBL yang dikembangkan dapat digunakan sebagai bahan ajar di SMA untuk materi koloid. Kata Kunci : alami, koloid, lembar kerja peserta didik, penjernihan air dengan koagulan alami, Project Based Learning (PjBL) This research aims to produce a practical Student Worksheet (LKPD) based on Project Based Learning (PjBL) on air purification experiments with natural coagulants on the topic of colloids for class XI Science SMA/MA chemistry learning. The participants in this study were 12 class XII students at one of the public high schools in the city of Bandung. The research method used was educational design research, but in this study it only reached the development stage. The results of the optimization of the practical procedure showed that Moringa seeds with a mass of 0.3 grams were the most effective coagulant among other natural coagulants such as papaya seeds, tamarind seeds, fresh Moringa leaves and dried Moringa leaves, the optimal time variation for purifying water was 12 hours, and not pH changes occur both before and after the coagulation process. The practicum Student Worksheet (LKPD) that had been prepared was tested for suitability by validators consisting of 3 UPI Chemistry Education lecturers and 2 high school chemistry teachers. The results of the feasibility test regarding the suitability of components in the LKPD with the PjBL stages, suitability of concept, grammar, as well as layout and appearance are included in the very good category. The results of student responses to the LKPD practicum that were developed were included in the very good category, as well as the results of student responses to practicum activities using the LKPD practicum that were developed were also included in the very good category, so that the PjBL-based LKPD practicum that was developed could be used as teaching material in high school for colloid material.
