Hasil penelitian mengungkap bahwa indigenous knowledge masyarakat adat Osing Desa Kemiren mayoritas masih disimpan dan ditransfer secara lisan dari generasi ke generasi yang menimbulkan distorsi terhadap indigenous knowledge yang dimiliki. Akan tetapi, saat ini masyarakat adat Osing Desa Kemiren sudah mulai menerapkan tahapan knowledge preservation yang terdiri atas selection, storage, dan actualization meskipun belum secara keseluruhan. Implementasi tahap selection tampak pada upaya masyarakat Desa Kemiren untuk temu kenali dalam rangka membuat pemetaan partisipatif dan identifikasi potensi desa. Indigenous knowledge yang mereka miliki juga disimpan dalam bentuk elektronik dan tercetak. Selain itu, masyarakat adat Osing Desa Kemiren juga masih melibatkan indigenous knowledge dalam menentukan keputusan serta menjalankan berbagai ritual adat dalam kehidupan sehari-hari sebagai bentuk aktualisasi. Kendala yang dihadapi dalam preservasi indigenous knowledge ini adalah keterbatasan sumber daya manusia, biaya, dan waktu.
