Zeolit merupakan material alam yang berpori tinggi dan biasa digunakan sebagai adsroben etilen pada buah. Namun kemampuan absorbsi etilen pada zeolit yang berukuran nano masih perlu dieksplorasi lebih dalam terutama waktu aktivasi kimia. Penelitian ini bertujuan untuk mengetahui waktu aktivasi kimia terbaik dalam mengaktivasi nano absorben yang telah diaktivasi fisik sebelumnya. Zeolit dihaluskan dengan menggunakan planetary ball milling, kemudian di aktivasi secara fisik menggukan kalinasi pada suhu 400°C selama 4 jam. Zeolit selanjutnya di aktivasi neggunakan asam klorida dengan variasi waktu selama 2, 4, 6, 24, dan 48 jam. Nano zeolit selanjutnya di uji gugus fungsi, morfologi, laju penyerapan dan juga sensitivitas terhadap zeolit. Hasil penelitian menunjukkan aktivasi nano zeolit selama 24 jam menunjukkan hasil penyerapan serta sensitivitas terbaik dalam menyerap gas etilen. Kemampuan yang ditemukan pada penelitian ini menunjukkan nano zeolit dapat digunakan untuk mengatur masa simpan produk pasca panen serta pengendali kematangan produk pertanian.
