Abstract

Penelitian ini bertujuan untuk mengetahui besarnya biaya, penerimaan, pendapatan dan kelayakan usaha peternakan ayam broiler di Distrik Prafi. Hasil penelitian ini diharapkan dapat menjadi informasi bagi peternak dan masyarakat agar dapat mengetahui penggunaan faktor-faktor produksi dan dapat menganalisis pendapatan usaha peternakan ayam broiler, serta pelaksanaan diseminasi tentang hasil pengamatan dan wawancara secara langsung dilapangan yang telah dilakukan. Pengumpulan data dilakukan melalui wawancara dan pengamatan, kemudian Analisis data yang digunakan pada penelitian ini yaitu analisa statistik deskriptif yaitu dengan menghitung rata–rata pendapatan, persentase, menghitung besarnya sampel dan melakukan penyederhanaan data serta penyajian data dengan menggunakan tabel. Pendapatan rata-rata peternak ayam broiler di Distrik Prafi Kabupaten Manokwari pada skala usaha 500 sebesar Rp.6.317.266/periode, sedangakan pada skala usaha 1000 sebesar Rp.14.510.252/periode. Keseluruhan Pendapatan rata-rata peternak ayam broiler per ekornya sebesar Rp.14.330,26. Analisis kelayakan usaha R/C pada peternakan ayam broiler di Distrik Prafi Kabupaten Manokwari dinyatakan menguntungkan, efisien dan layak untuk di kembangkan. Faktor-faktor yang mempengaruhi hasil produksi yaitu jenis doc, jenis pakan, tata cara perkandangan, pencegahan penyakit dan pemasaran hasil produksi. Efisiensi penggunaan faktor-faktor tersebut dinyatakan pada penilaian index performance (IP) yang dimana pada responden 1 responden 2 dan responden 3 masuk dalam kategori kurang, sedangkan pada responden 4 masuk dalam kategori baik

Abstract

Poultry production contributes significantly to the agricultural economy. Nutrition is one important factor in having competent poultry production. Currently, there is a lot of research about natural alternatives or feed additives that are low in cost and can help increase the overall performance and improve poultry health conditions without any adverse effects. Macroalgae such as green seaweeds can meet these parameters. It is easily available and is considered a rich source of proteins, polysaccharides, carbohydrates, vitamins, minerals, pigments, and antioxidants. Most often, seaweeds are used as feed additives for broiler chickens as they can induce a beneficial impact on production parameters (body weight (BW), average daily gain (ADG), feed consumption (FC), and feed conversion ratio (FCR) and meat quality. However, there are several challenges in using green seaweed as a protein alternative for broiler chickens such as its toxic and antinutritional components, as well as varying available supply due to seasonal effects, diseases, location, and environmental pollution. Furthermore, the main objective of this review is to evaluate the different research conducted on green seaweed as a potential protein source in broilers.

Abstract

The study of the development and growth of cattle from birth to slaughter allows the identification of early individuals. The objective of this study were to identify the non-linear model with the best fit to describe the growth curve of Angone cattle. Data of live weights measurements in the range from birth to 720 days of age of 47 animals were used. The evaluated non-linear models were Gompertz, Von Bertalanffy, Logistic and Brody. The model fitness was compared using the:  coefficient of determination, adjusted coefficient of determination, Akaike and Bayesian information criteria and mean square error as statistical criteria, and biological criteria the instantaneous growth rate and inflection point. Higher asymptotic weight (A) was observed for the Brody model (157.5 kg) and inverse behavior was observed for the maturing rate (K) with values ranging from 0.002 kg/day to 0.005 kg/day, demonstrating lower precocity of the evaluated group. Behavior supported by the instantaneous growth rate where gains of 0.030 kg/day were observed for the Gompertz model, 0.100 kg/day for the Logistic model, 0.127 kg/day for the Brody model and 0.168 kg/day for the Von Bertalanffy model. The Brody model provides better goodness of fit.

Abstract

Salah satu itik lokal yang memiliki kemampuan produksi telur yang tinggi yaitu Itik Magelang dengan ciri khas kalung putih di lehernya dengan warna bulu pada dada, punggung, dan paha didominasi oleh warna cokelat tua dan muda. Penentuan kualitas telur yang baik dapat dibedakan melalui dua hal yaitu kualitas internal dan eksternal. Metode penentuan kualitas eksternal telur dapat dilakukan dengan mengukur berbagai parameter quantitative eksternal kualitas telur antara lain berat telur, panjang telur, lebar telur, keliling panjang, keliling lebar, dan volume telur. Penelitian ini bertujuan untuk mengobservasi parameter eksternal telur itik Magelang yang berada di Kabupaten Magelang. Hasil penelitian terkait parameter eksternal kualitas telur Itik Magelang diperoleh rata-rata dan standar deviasi dari berat telur, panjang telur, lebar telur, keliling panjang, keliling  lebar, dan volume telur secara berturut-turut adalah 66,78 ± 5,30 gram, 5,72± 0,27 cm, 4,57± 0,16 cm, 16,45 ± 0,62 cm, 14,71 ± 0,55 cm, dan 60,95 ± 5,56 ml.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui dinamika populasi dan struktur populasi peternakan sapi peranakan ongole (PO) di Desa Karangrejo, Karanggadung, dan Ampelsari Kecamatan Petanahan, Kabupaten Kebumen. Penentuan lokasi ditentukan dengan metode purposive sampling. Analisis data menggunakan analisis statistik deskriptif dengan menghitung jumlah. Hasil penelitian yang telah dilakukan menunjukan bahwa jumlah ternak sapi PO di Desa Karangrejo, Karanggadung dan Ampelsari Kecamatan Petanahan Kabupaten Kebumen yaitu 172 ekor. Struktur populasi terdiri dari jantan dewasa 7 ekor (4,07%), betina dewasa 81 ekor (47,09%), jantan dara 6 ekor (3,49%), betina dara 22 ekor (12,79%), pedet jantan 27 ekor (15,70%) dan pedet betina 29 ekor (16,86%). Dinamika populasi terdiri dari persentase kelahiran 30,81%, pembelian 9,88%, kematian 1,16%, angka penjualan 19,19%, dan natural increase 29,65%. Hasil penelitian dilihat dari umur responden tertinggi antara 15 sampai 63 tahun  dengan jumlah 50 orang (83,34%), tingkat pendidikan tertinggi hanya dibangku SMP dengan jumlah 23 orang (38,33), pekerjaan tertinggi mayoritas petani dengan jumlah 46 orang (76,67%), lama beternak tertinggi rentan 10 sampai 20 tahun sebanyak 26 orang (43,33%) dan skala kepemilikan ternak terbanyak antara 1 sampai 5 tahun dengan jumlah 46 orang (76,67%).
