Judul: Percentage Weight of Commercial Cutsof Carcass and Organs of Broiler Chickens with Feed Containing Garlic Treatment.
Abstrak: Pemanfaatan ayam ras pedaging menyimpan resiko bagi konsumen, karena penggunaan berbagai jenis Antibiotic Growth Promoter (AGP). Studi pada bawang putih sebagai alternatif dari promotor pertumbuhan produksi ternak dilakukan dan efek menguntungkan pada pertumbuhan dan daya cerna. Penelitian ini bertujuan mengkaji persentase bobot potongan komersial dan organ ayam broiler yang diberi pakan dengan penambahan bawang putih sebanyak 3%. Rancangan percobaan penelitian ini menggunakan RAL dengan 4 perlakuan yaitu, pakan kontrol (P0), bawang putih segar P1, bawang putih kering P2 dan bawang hitam P3 dengan 5 ulangan. Pengambilan sampel dilakukan dengan memotong bagian karkas menjadi 4 bagian yaitu, dada, paha, sayap, dan punggung lalu diambil organ dalam meliputi hati, ampela, jantung, limpa, dan bursa fabricius. Data yang diperoleh dianalisis secara statistik dengan menggunakan sidik ragam (analysis of variance/ ANOVA) menggunakan aplikasi SPSS. Pemberian olahan bawang putih sebesar 3% sebagai subtitusi AGP tidak memberikan pengaruh yang nyata (P>0,05) terhadap persentase bobot potongan komersial dan persentase bobot organ ayam broiler, perlu penelitian lanjutan menggunakan dosis penambahan olahan bawang putih yang berbeda., The use of broiler chickens poses a risk to consumers, due to the use of various types of Antibiotic Growth Promoter (AGP). Studies on garlic as an alternative of a growth promoter in livestock production were carried out and its beneficial effects on growth and digestibility were carried out. This study aims to determine the percentage of commercial slaughter weight and organs of broiler chickens fed with the addition 3% of garlic. The experimental design of this study used RAL with 4 treatments namely, control feed (P0), fresh garlic P1, dry garlic P2 and black garlic P3 with 5 replications. Sampling was carried out by cutting the carcass into 4 parts, chest, thigh, wings and back and then taking the internal organs including liver, gizzard, heart, spleen, and bursa fabricius. The data obtained was analyzed statistically using analysis of variance (ANOVA) using the SPSS application. Provision of processed 3% garlic as a substitute for AGP did not have a significant effect (P> 0,05) on the percentage of commercial slaughter weight and the percentage of broiler organ weight, further research is needed using different added doses of processed garlic

Judul: Pemberian Tepung Pupa Ulat Sutera dan Tepung Bawang Putih terhadap Profil Darah dan Persentase Organ Dalam Ayam Broiler.
Abstrak: This research was aimed to investigate the effect of dietary silkworm pupae meal (SPM) and garlic meal (GM) and its combinations on blood profiles, visceral organ weight, and carcass pecentage of broiler chicken. The experiment used Ross strain chicks in a Completely Randomized Design 3 x 2 factorial with 3 replications and 10 chicks for each replication. Factor A was SPM level substitute fishmeal (FM) in ration (0%, 25%, and 50%), factor B was GM level in ration (0% and 2.5%). The treatments were: P0 = control diet, containing FM without GM; P1 = control diet+2.5% GM; P2 = ration with 25% SPM without GM; P3 = ration with 25% SPM+2.5% GM; P4 = ration with 50% SPM without GM; and P5 = ration with 50% SPM+2.5% GM. There were no negative effect in blood profiles, carcass and visceral organ yield affected by treatments. Silkworm pupae meal can replace 50% of fish meal utilization and could be applied as an alternative protein source in broiler ration.

Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
