<![CDATA[Improving carcass quality can be achieved through the utilization of natural feed additives, one of which is by giving fermented pineapple fruit peel extract (Ananas comosus L. Merr). This study aims to determine the effect of giving fermented pineapple fruit peel extract (Ananas Comous L. merr) on the physical composition of Kampung Unggul Balitbangtan (KUB) carcasses. This research was conducted at Sesetan Farm, Faculty of Animal Husbandry, Udayana University, located at Jalan Raya Sesetan, Gang Markisa No. 6, Denpasar, Bali for 8 weeks. The design used was a completely randomized design (CRD) with 4 treatments and 5 replicates, so there were 20 experimental units. Each experimental unit contained 3 two-week-old KUB chickens. The four treatments were the level of fermented pineapple peel extract in drinking water, namely 0%, 11%, 12%, and 13% for treatments P0, P1, P2 and P3, respectively. The observed variables were carcass weight, meat percentage, bone percentage and subcutaneous fat percentage. The results showed that the physical composition of carcasses in treatments P1, P2, and P3 were not significantly different (P>0.05) compared to P0. Based on the results of the study, it can be concluded that the provision of fermented pineapple peel extract (Ananas Comous L. merr) through drinking water at the level of 11%, 12%, and 13% has no effect on the physical composition of the carcass of Kampung Unggul Balitbangtan (KUB) Chicken. ABSTRAK Peningkatan kualitas karkas dapat diupayakan melalui pemanfaatan feed additive alami, salah satunya dengan pemberian ekstrak kullit buah nanas (Ananas comosus L. Merr) yang difermentasi. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak kulit buah nanas (Ananas comous L. Merr) terfermentasi terhadap komposisi fisik karkas Ayam Kampung Unggul Balitbangtan (KUB). Penelitian ini dilaksanakan di Farm Sesetan, Fakultas Peternakan Universitas Udayana, yang berlokasi di Jalan Raya Sesetan, Gang Markisa No. 6, Denpasar, Bali selama 8 minggu. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan, sehingga terdapat 20 unit percobaan. Setiap unit percobaan berisi 3 ekor ayam KUB berumur dua minggu. Keempat perlakuan tersebut adalah level ekstrak kulit buah nanas terfermentasi dalam air minum yaitu 0%, 11%, 12%, dan 13% masing-masing untuk perlakuan P0, P1, P2 dan P3. Variabel yang diamati adalah bobot karkas, persentase daging, persentase tulang dan persentase lemak subkutan. Hasil penelitian menunjukkan bahwa komposisi fisik karkas pada perlakuan P1, P2, dan P3 berbeda tidak nyata (P>0,05) dibandingkan dengan P0. Berdasarkan hasil penelitian dapat disimpulkan bahwa pemberian ekstrak kulit nanas (Ananas Comous L. merr) terfermentasi melalui air minum pada level 11%, 12%, dan 13% tidak berpengaruh terhadap komposisi fisik karkas ayam Kampung Unggul Balitbangtan (KUB).]]>
