Penentuan kadar aluminium secara SSA dilakukan dengan menganalisis larutan sampel secara langsung, sedangkan analisis secara spektrometri tampak dilakukan dengan perlakuan awal ekstraksi menggunakan pereaksi 8-hidroksikuinolin dalam kloroform. Absorbansi diukur dengan spektrometer ultra ungu-tampak pada panjang gelombang 408 nm. Hasil penelitian menunjukkan konsentrasi rata-rata secara SSA adalah 81,01 ± 0,95 ppm dan secara spektrometri tampak adalah 79,70 ± 1,64 ppm. Hasil uji t-student menyatakan bahwa t eksperimen sebesar 0,86 lebih kecil daripada t tabel yang besarnya 2,31 untuk P = 95%. Hal ini dapat disimpulkan bahwa kedua metode tersebut tidak berbeda secara nyata.}, issn = {2597-9914}, pages = {39--41} doi = {10.14710/jksa.2.2.39-41}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/18902} }
