Elektroda komposit graphene oxide-nanozeolite  dibuat dengan mensitesis graphene oxide dengan metode improved hummer dan mensitesis nanozeolite dengan metode  mechanicall milling. Elektroda komposit graphene oxide zeolite digunakan untuk mendeteksi aspirin secara siklik voltametri.  Pengukuran elektroda komposit graphene oxide zeolite  untuk aspirin secara siklik voltametri dipengaruhi oleh beberapa faktor yaitu komposisi elektroda , pH larutan , waktu deposisi, dan laju pindai. Deteksi aspirin dengan elektroda komposit graphene oxide-nanozeolite secara siklik voltametri memiliki komposisi elektroda optimum pada perbandingan graphene oxide:paraffin:zeolite  yaitu 3:2:5, pada pH optimum pengukuran aspirin yaitu 4 dengan waktu deposisi optimum 5 detik dan laju pindai 100 mV/detik. Elektroda komposit graphene oxide zeolite memiliki batas deteksi 0,0611 ppm dengan persen perolehan kembali 99,612 %. Elektroda komposit graphene oxide zeolite menunjukan sensitivitas dan selektivitas  yang baik.

Graphene oxide-nano zeolite composite electrodes manufactured by graphene oxide synthesizes with enhanced Hummer methods and nano zeolite synthesis with the Mechanical milling method. Graphene oxide zeolite composite electrodes are used to detect aspirin in cyclic voltammetry.  Measurements of graphene oxide zeolite composite electrodes for cyclic voltammetry aspirin are influenced by several factors i.e. electrode composition, pH, deposition time, and scanning rate. Detection of aspirin with graphene oxide zeolite composite electrodes in cyclic voltammetry has an optimum electrode composition in the ratio of graphene oxide: paraffin: zeolite is 3:2:5, at optimum pH measurement of aspirin 4 with optimum time deposition of 5 second and optimum scan rate at 100 mV/s. Graphene oxide-zeolite composite electrodes have a detection limit of 0.0611 ppm with a percent regained 99.612%. Graphene oxide zeolite composite electrodes show good sensitivity and selectivity.
