Abstract

A study was conducted to determine the effects of Sauropus androgynus leaf extract on growth, carcass quality and the number of fecal microorganisms in broiler chickens. Forty-eight male Arbor Acres broiler chickens (21-d-old) obtained from a commercial hatchery were used in the present study. Experiment consisted of four treatment groups with four pen replicates of three broilers allotted randomly to each dietary treatment from day 21-42 old. One group was the control with no additional Sauropus androgynus leaf extract (SAE) (P0), and other three groups were given drinking water supplemented with 1.5 g (PI), 3.0 g (P2) or 4.5 g SAE/l water (P3). The diet used was a commercial mix (Crude protein: 19% and Metabolizable Energy 3200 kcal/kg). Feed intake significantly reduced in P2 or P3 as compared with the control (P<0.05). A decrease in feed conversion ratio was observed in treatment groups as compared with Po (P<0.05). Abdominal fat, neck fat and liver fat content were significantly reduced by SAE (P<0.05), while carcass fat content was not significantly different. Number of fecal Escherichia coli in P1 or P3 (P<0,01) and fecal Streptococcus sp and Salmonella sp. were significantly (P<0,01) reduced by SAE supplementation as compared with the control, while fecal Bacillus subtilis in P2 and Lactobacillus sp. in P1 (P<0,01) were significantly higher as compared with other groups. SAE (P2 or P3) also significantly improved meat taste, shank color but lowered meat color (P<0.05) as compared with the control group. It was found that the number of fecal Streptococcus sp was suitable to predict abdominal fat. In conclusion, the inclusion of SAE at 4.5 g/l drinking water resulted in the best performance and carcass quality.   Key words: Sauropus androgynus leaf extract, fat accumulation, broilers

Abstract

Energi dan Sumber Daya Mineral (ESDM) sebagai unsur yang merupakan kebutuhan utama pada suatu Negara membutuhkan kajian untuk memprediksi ketersediaannnya. Prediksi ini dilakukan menggunakan model autoregressive yang diimplementasikan pada data time series dan dioptimasi menggunakan Algoritma Genetika. Berdasarkan hasil observasi yang dilakukan untuk pencarian parameter algoritma genetika, diperoleh parameter terbaik yaitu ukuran populasi pada nilai 100 dan 200 sedangkan probabilitas pindah silang bernilai 0.8 dan probabilitas mutasi nilainya 0.1 dengan akurasi MAPE yang diperoleh di bawah 25%. Prediksi yang menghasilkan MAPE terbaik adalah prediksi yang menggunakan data latih sebesar 85% dan data uji sebesar 15%. Hasil akhir dari prediksi adalah adalah ketersediaan gas alam dan batubara termasuk ke dalam kategori tidak krisis, sedangkan ketersediaan minyak bumi mengalami krisis.Kata kunci: Prediksi, Algoritma Genetika, Energi, autoregressive, time series.
