<![CDATA[Penelitian ini bertujuan untuk mengembangkan instrumen penilaian kinerja berbasis pendekatan saintifik pada materi pengukuran kelas X SMA untuk mengukur kinerja yang valid dan reliabel. Penelitian ini menggunakan penelitian pengembangan Borg dan Gall. Penelitian ini dilakukan di Universitas Negeri Jakarta pada bulan Agustus - November 2017. Tahap uji coba ke peserta didik dilakukan di Kelas X SMAN 73 Jakarta. Penelitian ini menggunakan adalah jenis research and development, studi pengembangan yang dilakukan mengadopsi siklus Borg dan Gall, dengan tahapan studi literature (Research and information collecting), perencanaan (Planning), Pengembangan produk awal (Develop preliminary form of product), Uji coba lapangan skala terbatas (Preliminary field testing), revisi produk (Main product revision), Uji Coba Skala utama (Main field testing), Penyempurnaan hasil uji coba skala utama (Operational product revision). Uji validasi produk (Operational field testing), melakukan revisi akhir (Final product revision) dan Penyebarluasan produk yang dikembangkan (Dissemination and implementation ). Instrumen diujikan secara terbatas pada peserta didik kelas X SMA N 73 Jakarta, hasil uji validitas butir dari 57 butir menjadi 48 butir yang valid. Uji Reliabilitas menggunakan Alpha Crobach. Hasil r hitung 0,864 dimana r tabel 0,334, berdasarkan hasil penelitian instrumen penilaian kinerja berbasis saintifik dapat mengukur kinerja pada kegiatan pembelajaran fisika materi pengukuran. This study aims to develop student performance appraisal instruments based on the scientific approach of student performance on high school physics measurement material for a valid and reliable result. This study uses research and development of Borg and Gall. It was conducted at the Jakarta State University in August - November 2017. In the testing phase to the students conducted in X Class of 73 Jakarta Senior High School. It uses the type of research and development, the development studies were conducted using the Borg and Gall cycles, with phase of literature study research and information collecting, planning, develop preliminary form of product, preliminary field testing, main product revision, main field testing, operational product revision, operational field testing, final product revision and dissemination and implementation. The instrument is tested on a limited basis for students of grade X of 73 Jakarta Senior High School, the results of the analysis of the instrument that has been tested its validity have decreased the number of grains from 57 to 48 items valid. While the reliability test using Alpha Cronbach. From the calculation obtained r count 0,864 with r table 0,334, from the results of this study can be concluded that the instruments based on scientific performance appraisal meet the requirements and feasible to be used as an instrument of performance appraisal on the learning activity of physics measurement material.
