This research was conducted on May 30th, 2018 to July 10th, 2018 at the Commercial Zone and Animal Laboratory (CZAL) and Animal Husbandry Laboratory, Department of Animal Husbandry, Faculty of Agriculture, University of Bengkulu. The design used was a Completely Randomized Design (CRD). This study used 100 native chickens with 5 weeks of age consisting of 5 treatments and 4 replications, each of which consisted of 5 native chickens. The treatments were, PO: Control, P1: adding 1.5% Senduduk leave, P2: adding 2.5% Senduduk leave, P3: adding 3.5% Senduduk leave, P4: adding 4.5% Senduduk leave. The parameters measured in this study used a sample of 20 10-week-old chickens, were blood lipid fraction consisting of triglycerides, cholesterol, HDL (high-density lipoprotein), LDL (low-density lipoprotein), VLDL (very low-density lipoprotein), a comparison index of LDL with HDL, and weight of internal organs consisting of liver, heart, lymph, gizzard, intestinal weight, and intestinal length. The data obtained were analyzed by variance (ANOVA). Further testing utilized the Duncan Multiple Test (DMRT) Test. The results showed that the administration of Senduduk leaf flour (Melastoma malabathricum L.) in the ration had a very significant cholesterol levels, significant effect (P <0.05) on, LDL-c levels, atherogenic index levels, but not significantly different (P> 0.05) on triglyceride levels, HDL levels, VLDL levels, and also not significantly different (P> 0.05) to the percentage of heart, spleen, gizzard, intestine, and intestinal length. Key words: leaf powder, buras chicken, blood lipid fraction, internal organ ABSTRAK Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian tepung daun Senduduk ( Melastoma malabathirium L.) dalam ransum terhadap fraksi lipid darah dan berat organ dalam pada ayam buras. Penelitian ini dilaksanakan pada tanggal 30 Mei 2018 sampai 10 Juli 2018 di Commercial Zone and Animal Laboratory (CZAL) dan Laboratorium Peternakan Jurusan Peternakan Fakultas Pertanian Universitas Bengkulu. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL). Penelitian ini menggunakan 100 ekor ayam buras berumur 5 minggu, terdiri 5 perlakuan 4 ulangan, setiap ulangan terdiri 5 ekor ayam buras. Perlakuan tersebut, TO: Kontrol, T1: menggunakan 1,5% daun Senduduk, T2: menggunakan 2,5% daun Senduduk, T3: menggunakan 3,5% daun Senduduk, T4: menggunakan 4,5% daun Senduduk. Paramater yang diukur pada penelitian ini menggunakan sampel sebanyak 20 ekor ayam berumur 10 minggu yakni fraksi lipid darah terdiri trigliserida, kolestrol, HDL (high-density lipoprotein), LDL (low-density lipoprotein), VLDL (verry low- density lipoprotein), index perbandingan antara LDL dengan HDL, dan berat organ dalam terdiri berat liver, berat jantung, berat limfa, berat gizzard, berat usus, dan panjang usus. Data yang diperoleh dianalisis dengan sidik ragam (ANOVA). Uji lanjut menggunakan Uji Duncan’s Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa pemberian tepung daun Senduduk (Melastoma malabathricum) dalam ransum berpengaruh sangat nyata (P<0.01) terhadap kadar kolesterol, berpengaruh nyata (P<0.05) terhadap kadar LDL-c, kadar index aterogenik, tetapi tidak berbeda nyata (P>0.05) terhadap kadar trigliserida, kadar HDL-c, kadar VLDL, dan juga tidak berbeda nyata (P>0.05) terhadap persentase berat hati, jantung, limpa, gizzard, usus, dan panjang usus. Kata Kunci: daun Senduduk, ayam buras, fraksi lipid darah, organ dalam
