The implementation of an integral concept in the real life was very broad, but the student' remains for it in the low category. The strategy of Scientific Debate was allegedly capable to enhance the students' ability in the integral concept. The most important part in the learning process of the Scientific Debate is learning materials and instruments as a means of evaluation. Learning materials and instruments are capable if can measure what should be measured and must have validity,

The development of learning materials contains a dish concept, examples of routine and non-routine problem, to exercise routine and of nonroutine the question, to reserve application problem. The results of the trial of the instruments was obtained significance value 0.42 that is means the experts have weigh the validity of the content of grains of matter uniformly. The significance value of the question validity is 0.82 it means advance category from the language and images. The significance value of reliability is 0.87 that is included in the advance category. The analysis of the difficulty degree shows the problem number 7 categories difficult, problem number 1, 2, 4, and 6 categories quite, and the problem numbers 3 and 5 categories easily. Analysis of the classification of the criterion power show the problem numbers 1, 2, and 3 is good quite, the problem number 4, 6, and 7 are good, as well as the problem of the number 5 included is excellent. Abstrak. Penerapan konsep integral dalam kehidupan nyata sangatlah luas, tetapi pemahanan mahasiswa masih berada dalam kategori rendah. Strategi Scientific Debate diduga mampu meningkatkan kemampuan mahasiswa dalam kalkulus integral. Bagian terpenting dalam proses pembelajaran Scientific Debate adalah bahan ajar dan instrumen sebagai alat evaluasi. Bahan ajar dan instrumen yang mampu mengukur apa yang semestinya diukur harus memenuhi validitas, reliabilitas, memiliki daya pembeda (DP), dan indeks kesukaran (IK) yang memadai. Pengembangan bahan ajar berisi sajian konsep, contoh soal rutin dan non-rutin, latihan soal rutin dan non-rutin, latihan soal aplikasi. Hasil uji coba instrumen diperoleh nilai signifikansi 0,42 artinya para penimbang telah menimbang validitas isi butir soal secara seragam. Nilai signifikansi validitas muka 0,82 artinya soal yang diujikan jelas dari sisi bahasa dan gambar. Nilai signifikansi reliabilitas 0,87 termasuk dalam kategori tinggi. Analisis tingkat kesukaran menunjukkan soal nomor 7 kategori sukar, soal nomor 1, 2, 4, dan 6 kategori sedang, dan soal nomor 3 dan 5 kategori mudah. Analisis klasifikasi daya pembeda menunjukkan soal nomor 1, 2, dan 3 termasuk cukup baik, soal nomor 4, 6, dan 7 baik, serta soal nomor 5 termasuk sangat baik. Kata Kunci: instrumen, scientific debate, validitas, reliabilitas, indeks kesukaran
