Kata Kunci : Instrumen Penilaian Kinerja, Laboratorium Biologi

Penelitian bertujuan untuk menghasilkan instrument penilaian kinerja laboratorium biologi  yang valid, reliabel dan praktis. Adapun parameter penelitian ini terdiri atas validitas, reliabilitas dan kepraktisan. Aspek kevaliditas ditinjau oleh dari hasil penilaian  instrument penilaian kinerja laboratorium biologi oleh para validator, skor yang diperoleh kemudian di analisis dengan menggunakan metode analisis deskriptif kuantitatif. Aspek reliabilitas ditinjau dari reliabilitas validasi  dan reliabilitas pengamat yang kemudian dianalisis menggunakan rumus Percentage of Agreement. Aspek kepraktisan ditinjau dari keterlaksanaan mengembangkan instrument penilaian kinerja laboratorium biologi  dan hasil angket guru). Hasil analisis data menunjukan validitas instrumen penilaian kinerja menggunakan mikroskop dan indikator univesal dikategorikan sangat valid, sedangkan penilaian kinerja membuat respirometer sederhana, membuat spirometer sederhana, mendemonstrasikan gerakan pernafasan dada dan pernafasan perut dikategorikan valid. Reliabilitas validasi (R ≥ 75%) dan reliabiltas Instrumen (R ≥ 75%) sehingga dikategorikan reliabel. Kepraktisan instrumen penilaian kinerja menggunakan mikroskop dan indikator universal, membuat alat respirometer sederhana dan spirometer sederhana, serta mendemonstrasikan gerakan pernafasan dada dan pernafasan perut dilihat dari keterlaksanaannya berturut-turut adalah 95.37% (sangat praktis), 93,18 % (sangat praktis), 97,22 % (sangat praktis), 99,26 % (sangat praktis), 91,07 % (sangat praktis),  82,18% (sangat praktis). Berdasarkan hasil angket guru instrumen penilaian kinerja Kepraktisan instrumen penilaian kinerja menggunakan mikroskop dan indikator universal, membuat alat respirometer sederhana, mendemonstrasikan gerakan pernafasan dada dan pernafasan perut dikategorikan sangat praktis, dan instrumen penilaian kinerja membuat spirometer sederhana diategorikan praktis.

ABSTRACT

J I Bari, Agata. 2020., Development of Biology Thesis Laboratory Performance Assessment Instrument, Science Education Study Program, Graduate of Surabaya State Universiry. Counselor : (I) Prof. Dr. H. Muslimin Ibrahim, M.Pd. dan (II) Dr. Yuliani, M.Si.

Keywords : Performance Appraisal Instrument, Biology Laboratory

This study aims to produce a valid, reliable and practical biology laboratory performance assessment instrument. The validity aspect was reviewed by the results of the assessment of the biological laboratory performance assessment instrument by the validators, the scores obtained were then analyzed using quantitative descriptive analysis methods. The reliability aspect is evaluated from the validation and reliability of the observer which is then analyzed using the Percentage of Agreement formula. The practicality aspect in terms of the feasibility of developing a biology laboratory performance appraisal instrument and the results of the teacher questionnaire were calculated using the practicality formula adopted from Widoyoko (2013). The results of the data analysis show the validity of performance assessment instruments using a microscope and universal indicators is categorized as very valid, while the performance appraisal makes a simple respirometer, makes a simple spirometer, demonstrates chest breathing and abdominal breathing movements categorized valid. The validation reliability (R ≥ 75%) and the reliability of the Instrument (R ≥ 75%) so that it is categorized as reliable. The practicality of performance appraisal instruments using a microscope and universal indicators, making a simple respirometer and a simple spirometer, as well as demonstrating chest and abdominal breathing movements seen in succession are 95.37% (very practical), 93.18% (very practical), 97 , 22% (very practical), 99.26% (very practical), 91.07% (very practical), 82.18% (very practical). Whereas based on the results of the teacher's questionnaire performance appraisal instrument Practical performance appraisal instruments using microscopes and universal indicators, making simple respirometer devices, demonstrating chest breathing and abdominal breathing movements are categorized very practical, while performance assessment instruments making simple spirometers are categorized as practical.
