Telah dilakukan uji coba perangkat pembelajaran dan instrumen untuk mengukur tingkat kompetensi mahasiswa. Kompetensi yang diukur meliputi penguasaan konsep dan motivasi belajar analisis instrumentasi. Penguasaan konsep analisis instrumentasi dinilai melalui tes, dan motivasi belajar diukur melalui koesioner motivasi belajar (KMB). Hasil validasi perangkat pembelajaran dinyatakan valid dan layak untuk digunakan. Hasil uji coba soal tes penguasaan konsep terhadap 135 responden diperoleh informasi dari 30 soal tes penguasaan konsep analisis instrumentasi hanya ada 25 soal yang valid dan instrumen pengukuran penguasaan konsep secara keseluruhan reliabel dengan reliabilitas 0,845. Instrumen KMB yang telah diuji cobakan terhadap 312 responden diperoleh hasil dari 25 pernyataan hanya ada 21 item yang valid dengan reliabilitas komposit sebesar 0,9329. Penerapan model pembelajaran praktikum Kimia Analisis Instrumen berbasis proyek diperoleh hasil 21 mahasiswa memiliki peningkatan penguasaan konsep kategori rendah dan 15 mahasiswa kategori sedang. Adapun tingkat motivasi belajar diperoleh 21 mahasiswa kategori sedang dan 15 kategori tinggi. Mahasiswa perlu dibiasakan melakukan praktikum berbasis proyek agar kompetensinya meningkat.
