Pengembangan Lembar Kegiatan Peserta Didik Berbasis Contextual Teaching and Learning pada Sub-materi Interaksi antar Komponen Ekosistem

Worksheet development based on Contextual Teaching and Learning in  sub-material interaction beetween ecosystem components 

Pengembangan LKPD berbasis Contextual Teaching and Learning pada sub materi Interaksi antar komponen ekosistem bertujuan untuk menghasilkan LKPD yang layak dipergunakan dalammpembelajaran biologi, melatihkan keterampilan berpikir kritis, dan mendeskripsikan kelayakan LKPD dilihat dari validitas, kepraktisan, dan keefektifan. Model pengembangan LKPD yang digunakan adalah Instruksional fenrich yaitu analisis, pernecanaan, perancangan,pengembangan, implemmentasi, serta evaluasiidan revisi. Validitas LKPD diperoleh dari 2 dosen Biologi dan 1 guru Biologi. Kepraktisan LKPD ditinjau dari keterlaksanaan LKPD. Keefektifan LKPD ditinjau dari hasil belajar dan respon peserta didik. Penelitian ini menggunakan subjek uji coba terbatas pada 20 peserta didik SMA Negeri 12 Surabaya. Hasil penelitian ini yaitu kriteria interpretasi skor validitas LKPD sebesar 3,86 dengan kategoriiSangat valid. Kepraktisan  LKPD memperoleh presentase keterlaksanaan pada pertemuan 1 sebesar 91,6% dan pertemuan 2 sebesar 98,3% termasuk kategori sangat praktis. Keefektifan ditinjau dari hasil belajar memperoleh hasil skor N-gain tes kognitif dengan rata-rata skor 1 dan tes ketercapaian indikator berpikir kritis dengan rata-rata skor 0,77 termasuk kategori Tinggi. Keefektifan juga ditinjau dari hasil respon peserta didik memperoleh persentase 98,05 % termasuk kategori sangat efektif. Penelitian ini menghasilkan LKPD berbasis  Contextual Teaching and Learning pada sub materi Interaksi antar komponen ekosistem untuk melatihkan keterampilan berpikir kritis yang layak digunakan dalam pembelajaran.

Kata Kunci: LKPD, contextual teaching and learning, keterampilan berpikir kritis, interaksi antar komponen ekosistem. 

Worksheet development based on Contextual Teaching and Learning in  sub-material interaction beetween ecosystem components was purposed to produce LKPD that is suitable for use in biology study, practice critical thinking skills, and describe the feasibility of the worsheet validity, practicality, and effectiviness. This study was a development research wich used instructional model of Fenrich which consists of six stages including the analysis, planning, design, development, implementation and evaluationnand revision stages. The validity was reviewed by 2 lectures and a biology teacher. The practicality in terms of implementation of worksheet. The effectiveness of worksheet in terms of student learning outcomes and responses. The study used a limited trial subject to 20 students of Surabaya 12 Senior Highr School. The result of study are the interpretation criteria of the validity score of 3,86 with a very validdcategory. Practicality of worksheet get a percetage of feasibility at meeting 1 amounted to 91,6% and meeting 2 amounted to 98,3% including a very practical category. Effectiveness showed the result of learning to get N-gain score cognitive test with an average score of 1 and and achievement of critical thinking indicators with an average score of 0,77 with a highicategory. Effectiveness is also judging from the results of the responsessof studenst obtained a percentage of 98,05% including the category of very effective.  The research produces Contextual Teaching and Learning based on sub-material interaction beetween ecosystem components to train critical thinking skills that are appropriate for use in learning.
