Penelitian ini bertujuan menguji sifat fisik biochar dari limbah kulit kakao
dan pengaruhnya terhadap saluran pencernaan ayam kampung. Sebanyak 160 ekor
DOC ayam kampung jenis Sentul terseleksi yang dipelihara hingga panen umur 63
hari (9 minggu), sampel yang digunakan pada penelitian sebanyak 16 ekor yang
terdiri dari 2 ekor ayam jantan dan 2 ekor ayam betina dari masing-masing
perlakuan. Penelitian ini terdiri dari perlakuan P0 (pakan komersial), P1 (pakan
penelitian tanpa biochar), P2 (pakan penelitian mengandung biochar 1%), dan P3
(pakan penelitian mengandung biochar 2%). Rancangan percobaan yang
digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4
ulangan. Pengukuran peubah yang diamati meliputi kadar air, aktivitas air, berat
jenis, ukuran partikel dari biochar dan pakan perlakuan, serta bobot badan akhir,
panjang dan bobot saluran pencernaan ayam kampung umur 63 hari. Hasil
penelitian menunjukkan bahwa sifat fisik biochar limbah kulit kakao dan pakan
perlakuan tidak berbeda nyata terhadap berat jenis. Hasil nilai kadar air yang
berkisar antara 7,078%-10,78% dan aktivitas air yang berkisar antara 0,65-0,76
menunjukkan bahwa kadar air pada pakan penelitian ini masih dibawah standar dan
aman untuk penyimpanan sesuai dengan standar SNI tahun 2013 yang menyatakan
bahwa kadar air maksimum yaitu 14%, sedangkan nilai rataan aktivitas air, berat
jenis dan ukuran partikel termasuk dalam kisaran normal. Pemberian pakan
komersial, pakan mengandung biochar, dan pakan tanpa mengandung biochar
tidak memberikan pengaruh pada panjang dan bobot saluran pencernaan ayam
kampung. This study aimed to examine the physical properties of biochar from cocoa
shell waste and its effect on the digestive tract of native chickens. A total of 160
selected Sentul native chicken DOCs were kept until harvest at 63 days (9 weeks),
the sample used in this study consisted of 16 chickens consisting of 2 male chickens
and 2 female chickens from each treatment. This study consisted of treatments P0
(commercial feed), P1 (research feed without biochar), P2 (research feed
containing 1% biochar), and P3 (research feed containing 2% biochar). The
experimental design used was a completely randomized design (CRD) with four
treatments and four replications. Measurement of the observed variables included
water content, water activity, specific gravity, particle size of biochar and treatment
feed, as well as final body weight, length and weight of the digestive tract of native
iv
chickens aged 63 days. The results showed that the physical properties of cocoa
husk waste biochar and treated feed were not significantly different with respect to
specific gravity. The results of the water content values ranging from 7.078%-
10.78% and water activity ranging from 0.65-0.76 showed that the water content in
the feed of this study was still below the standard and safe for storage according to
the 2013 SNI standard which states that the maximum water content is 14%, while
the average value of water activity, specific gravity and particle size are in the
normal range. The treats of commercial feed, feed containing biochar, and feed
containing non-biochar did not affected the length and weight of the digestive tract
of native chickens.
