ABSTRAKPenelitian ini dilakukan untuk mengetahui sifat fisik dan organoleptik abon daging itik afkirdengan penambahan buah nangka muda. Bahan yang digunakan adalah daging itik afkir, buah nangka muda, bawang putih, bawang merah, kemiri, ketumbar, kelapa, gula merah, garam, air, dan minyak goreng. Rancanganpenelitian yang digunakan dalam penelitian ini yaitu rancangan acak lengkap terdiri dari 4 perlakuan (A0: 100% daging itik, A1: 85% daging itik dan 15% nangka muda, A2:70% daging itik dan 30% nangka muda,A3:55% daging itik dan 45% nangka muda) dengan3 ulangan untuk peubah fisik, dan 15 panelis untuk pengujian organoleptik.Hasil penelitian menunjukan bahwa penambahan buah nagka muda padaabon itik afkir tidak berpengaruh nyata terhadap pH dan rendemen abon. Sifat organoleptik (aroma, warna, rasa, dan tekstur)abon daging itik afkir tidak berbeda nyata dengan penambahan buah nangka muda.Katakunci: Abon, daging itik afkir, buah nangka muda, sifat fisik, sifat organoleptik.ABSTRACT This study was conducted to determine the physical characteristics and organoleptic qualities of spent duck abon with the addition of unripe jackfruit. The materials used were spent duck meat, unripe jackfruit, garlic, shallot, candlenut, coriander, coconut, brown sugar, salt, water, and cooking oil. The design used in this study is completely randomized design consisted of 4 treatment (A0: 100% duck meat, A1: 85% duck meat and 15% unripe jackfruit, A2: 70% duck meat and 30% unripe jackfruit, A3: 55% duck meat and 45% unripe jackfruit) with 3 repetition for physical variables, and 15 panelists for organoleptic test. The results of this study suggested that addition of unripe jackfruit in spent duck abon showed no significant difference for pH and rendemen. Organoleptic qualities (aroma, color, flavor and texture) of spent duck abon showed no significant difference with unripe jackfruit aditition.Keywords: abon, spent duck meat, unripe jackfruit, physical characteristic, organoleptic qualities
