INTISARIMastitis pada sapi perah merupakan salah satu penyakit yang menyebabkan penurunan kualitas dan produksi susu. Tujuan dari penelitian ini adalah untuk mengetahui dan mengukur kadar senyawa fenol dalam buah mengkudu (Morinda citrifolia) mentah, mengkal, dan matang, membandingkan daya hambat bakteri ekstrak buah mengkudu dan larutan celup puting komersial yang mengandung iodium 1,25% (komersial A) dan benzalkonium chloride 2% (komersial B). Penelitian ini menggunakan bakteri Staphylococcus aureus asal susu sapi penderita mastitis subklinis. Larutan yang digunakan untuk menghambat bakteri adalah ekstrak buah mengkudu, larutan komersial A dan komersial B. Hasil penelitian menunjukkan kadar fenol paling tinggi terdapat pada buah mengkudu matang. Berdasarkan analisis statistik menggunakan One Way Anova menunjukkan bahwa pemberian larutan yang berbeda memberikan efek nyata (P<0,05) dalam uji daya hambat bakteri. Namun demikian hasil uji lanjut menggunakan uji Duncan's Multiple Range Test (DMRT) terdeteksi bahwa daya hambat bakteri yang diberi ekstrak buah mengkudu dan larutan komersial A tidak menunjukkan perbedaan. Sedangkan larutan komersial B mampu menghambat bakteri Staphylococcus aureus paling baik dibandingkan dengan ekstrak buah mengkudu, komersial A dan kontrol. Kesimpulannya, ekstrak mengkudu mengandung antibakteri alami dengan daya hambat yang tidak berbeda nyata dengan larutan komersial A dan dapat digunakan sebagai larutan untuk celup puting.(Kata kunci: Fenol, Antibakteri alami, Morinda citrifolia) ABSTRACT Mastitis is one of the most harmful diseases on dairy cows because it reduced milk quality and production. The aim of this study was to determine the active compounds in the noni PendahuluanMastitis atau radang kelenjar ambing merupakan suatu penyakit yang dapat menyerang sapi perah, kambing perah atau kerbau perah (Setiadi, 1997), merupakan peradangan yang bersifat kompleks dengan berbagai variasi penyebab, derajat keparahan, lama penyakit, dan akibat penyakit yang beragam (Sudarwanto dan Sudarnika, 2008). Penyebab utama kerugian ekonomi dalam industri persusuan dan menurunkan produksi susu ialah mastitis (Azizoglu et al., 2013 59

This research aims to evaluate the quality of goat feces liquid biofertilizer with chicken excreta addition by aerobic and anaerobic fermentation. The data obtained from the research were statistically analyzed with Completely Randomized Design (CRD) Factorial Pattern with two factors. The first factor was addition level of the chicken excreta (0, 10, 20, and 30%) and the other factor was fermentation treatment (aerobic and anaerobic) condition with 3 replications for each treatment. Fermentation was conducted for 14 days. The observed parameters consisted of the chemical parameter (organic-C, N, P, and K) and the physical parameter (pH, temperature, and the odor). The addition of various level of chicken excreta and fermentation treatments in the process of producing goat feces liquid biofertilizer indicate significantly effect to increase the organic-C, total-N, NH4, P, K, compare with 5 and 10% liquid fertilizer treatment. The best quality of liquid biofertilizer produced by combining aerobic fermentation and the addition of 30% chicken excreta. Generally, chicken excreta able to increase the nitrogen and mineral content, and putting together with aerobic fermentation system of chicken excreta maximum to 30% can avoid overproduction of unpleasant odor.

Goat milk has specific chemical composition and physical properties. The purpose of this study was to investigate the change of milk quality and emulsion stability during 60 d frozen storage. Milk sample was taken from three Ettawah Crossedbred goats that were divided into three groups. Samples were frozen and stored for 0, 30 and 60 days. At the end of each storage periode, milk sample was thawed in the refrigerator and analyzed for total number of bacteria, chemical (acidity, pH, free fatty acids), physical (alcohol test, clot on boiling test) quality, and emulsion stability. The microbiological and chemical data were analyzed statistically using one way ANOVA, whereas physical quality and emulsion stabilty were expressed qualitatively. There were no change in the total bacteria, acidity, pH and free fatty acid (FFA) of milk during storage, whereas the assessment by 70% alcohol showed positive since 0 d. Emulsions stability changed after 30 d of storage. While, the clot on boiling (COB) test of milk was positive at 60 d of storage. Recommendation is frozen storage of goat milk should not longer than 30 d.

INTISARIPenelitian ini bertujuan untuk mengetahui dan membandingkan produksi dan komposisi susu kambing daerah dataran tinggi dan dataran rendah di Daerah Istimewa Yogyakarta. Kambing yang digunakan dalam penelitian adalah 10 induk laktasi kambing Peranakan Ettawa di masing-masing lokasi yaitu Kabupaten Kulon Progo dan Bantul. Data yang diambil terdiri dari kondisi lingkungan, konsumsi pakan, produksi dan komposisi susu yang terdiri dari kadar lemak, kadar protein, dan berat jenis. Pengukuran dilakukan dalam 3 ulangan, dengan tiap ulangan selama 7 hari, pada awal, pertengahan dan akhir periode. Konsumsi pakan diukur selama 21 hari. Produksi susu diukur dari hasil pemerahan pagi dan sore. Data yang diperoleh dianalisis statistik menggunakan analisis One way-Anova. Konsumsi nutrisi kambing di Kabupaten Kulon Progo lebih besar daripada Bantul (P<0,05). Rerata konsumsi bahan kering, protein kasar, serat kasar, dan total digestible nutrient kambing di Kulon Progo berturut-turut adalah 95,98 g; 14,26 g; 14,26 g, dan 0,06 kg/kg BB 0,75 sedangkan di Bantul 86,96 g; 10,87 g; 19,23 g, dan 0,05/kg BB 0,75 . Rerata produksi susu, kadar lemak, kadar protein, dan total bahan padat susu kambing di Kulon Progo adalah 501,71 g/hari; 4,84%, 4,41%, dan 13,26% sedangkan di Bantul 419,62±197,08 g/hari; 6,30%; 3,97%, dan 14,69%. Kesimpulan dari penelitian ini adalah kondisi lingkungan menyebabkan perbedaan produksi dan komposisi susu kambing Peranakan Ettawa salah satunya diakibatkan oleh perbedaan komposisi pakan dan konsumsi nutrien, sebagaimana hasil yang diperoleh di Kulon Progo dan Bantul.(Kata kunci: Dataran rendah, Dataran tinggi, Kambing Peranakan Ettawa, Komposisi susu, Produksi) ABSTRACT The objective of this study was to determine the differences of milk production and compotition of Ettawa Crossbred goats in highland and lowland area of Yogyakarta.

The purpose of the study was to investigate the effect of environmental and pre-milking sanitation on milk quality of dairy cow in the farmers. Milk quality were measured from samples that were taken from cows managed by farmers in Pakem, Sleman during the existing condition and implementation of treatment. Twenty three dairy cows were used to observed the effect of treatment, namely improve environmental sanitation and pre-milking. The treatment consisted of cleaning the floor stable, water and feed trough, washing the cow and udder, drying udder and discarded the first milk flow. The results showed that improving sanitation significantly decreased milk acidity from 0.19% to 0.14% and number of bacteria in milk. The treatments could also increase milk density and solid non fat. The study concluded that improving environmental sanitation and pre-milking gave significant effect to milk quality.
