The objective of this research was to investigate the characteristics and differences in quality milk of Water andSwamp buffalo milk in North Sumatera. This research was conducted used complete random design used 30buffalo from three breeding farm in North Sumatera. Buffalo milk were collecting from lactating buffaloes on threetraditional farms located at Patumbak, Lubuk Pakam, and Siborong-borong with extensive farming system. Theresult of this research shown milk production per day for Swamp buffalo is 1 1.5 l and Water buffalo is 6 8 l withquality of Swamp and Water buffalo sequentially are for protein 5.14 ± 0.37% and 4.68 ± 0.41%, fat content 7.52 ±0.98% and 4.13 ± 0.73%, non-fat dry matter (NFDM) 10.61 ± 0.78% and 11.5 ± 0.86%, moisture 81.87 ± 2.26% and80.33 ± 2.33%, milk density 1.030 and 1.036, and then Total Plate Count (TPC) 3.79 x 106 and 5.08 x 105, shownindicated that there ware significant difference in protein, fat content and NFDM (P<0.01). But there is nodifferences in moisture and milk density. TPC shown that Swamp buffalo milk has above the maximum microbespresent in milk. The conclusion of this research is milk production of Swamp buffalo less than River buffalo but hashigher in chemical quality of milk than River buffalo such as protein, NFDM and fat content. Amino acids in Swampbuffalo milk were higher than River buffalo milk. Althought buffalo has less milk production than cow but buffalomilk were higher in all quality tested parameters and have more potential than dairy cow to be developed becausemaintenance of buffalo in North Sumatera is still use traditional method and not yet leading to efforts to obtainmaximum production performance.

Water kefir merupakan minuman yang difermentasi oleh bakteri asam laktat (BAL) (Lactobacillus, Lactococcus dan Leuconostoc), khamir (Saccharomyces dan Candida), dan bakteri asam asetat (Aceterobacter) yang memiliki banyak keunggulan. Penelitian ini bertujuan untuk mengetahui pengaruh lama fermentasi terhadap viskositas, aktivitas antioksidan, dan organoleptik water kefir anggur merah. Desain percobaan yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 kali ulangan. Perlakuan yang dicobakan adalah variasi lama fermentasi yaitu 12 jam (T1), 24 jam (T2), 36 jam (T3), dan 48 jam (T4). Anggur yang digunakan adalah anggur merah, kefir grains 5%, dan gula sukrosa 8%. Data total BAL dan aktivitas antioksidan dianalisis secara deskriptif, sedangkan data viskositas dan organoleptik dianalisis dengan Anova. Hasil penelitian dapat disimpulkan bahwa perlakuan lama fermentasi menurunkan total BAL, menurunkan viskositas, meningkatkan aktivitas antioksidan. Water kefir anggur merah mengalami perubahan sifat organoleptik pada rasa, aroma, dan warna. Rasa dan aroma menjadi sangat asam, sementara warna menjadi agak pucat. Berdasarkan skala prioritas parameter yang diuji, lama fermentasi yang terbaik adalah 24 jam.Water kefir is a beverage fermented by lactic acid bacteria (LAB), yeast (Saccharomyces and Candida), and acetic acid bacteria (Aceterobacter) which have many advantages. This study aims to determine the effect of long fermentation on viscosity, antioxidant activity, and organoleptic from red grape water kefir. The experimental design used in this study was Completely Randomized Design (RAL) with 4 treatments and 5 replications. The experimental treatments were variation of fermentation time of 12 hours (T1), 24 hours (T2), 36 hours (T3), and 48 hours (T4). The wine used is red wine, grains kefir 5%, and 8% sucrose sugar. Total BAL data and antioxidant activity were analyzed descriptively, while viscosity and organoleptic data were analyzed by Anova. The results of this study can be concluded that the long treatment of fermentation decreases total BAL, decreases viscosity, increases antioxidant activity. Red grape water kefir experience changes in organoleptic properties of flavor, aroma, and color. The flavor and aroma become very sour, while the color becomes a bit pale. Based on the priority scale of the parameters tested, the best fermentation time is 24 hours.

Kefir adalah produk fermentasi susu yang mempunyai karakteristik khas yaitu campuran rasa asam, alkoholik dan karbonat. Pada umumnya kefir yang biasa dikonsumsi oleh masyarakat yaitu kefir optima yang merupakan pengadukan antara lapisan bening dan dan lapisan padatan setelah proses fermentasi. Penelitian ini bertujuan untuk mengetahui karakteristik kefir optima menggunakan bibit praktis terhadap nilai pH, total BAL, total padatan terlarut dan organoleptik. Materi yang digunakan dalam penelitian ini yaitu susu sapi segar yang diperoleh dari Kelompok Tani Ternak Rejeki Lumintu, desa Sumurejo, Gunung Pati, kefir grains, larutan garam fisiologis, MRSA, dan aquades. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 4 kali pengulangan. Parameter yang di uji adalah nilai pH, total bal, total padatan terlarut dan organoleptik. Perlakuan yang diberikan yaitu variasi konsentrasi starter bibit praktis yang meliputi T0 = (5% biji kefir), T1 = 1 : 6, T2 = 1 : 7, T3 = 1 : 8 dan T4 1 : 9. Data hasil uji nilai pH, total padatan terlarut, dan total BAL dianalisis dengan ANOVA dan organoleptik dianalisis menggunakan uji non-parametrik Kruskal Wallis Test. Hasil penelitian menunjukkan bahwa variasi konsentrasi berpengaruh nyata (P<0,05) terhadap nilai pH, total BAL dan total padatan terlarut. Pada organoleptik berbeda nyata (P<0,05) pada aroma dan tekstur sedangkan tidak berpengaruh nyata (P>0,05) terhadap rasa dan warna.

Adding fillers to kefir improves the stability and physical properties of kefir, so as to produce good kefir powder from the drying process. This study was conducted to determine the effect of skim milk addition as filler with different concentrations (0%, 2.5%, 5%, 7.5%, 10%) on the proximate, chemical, and microbiological properties of buffalo colostrum kefir powder using the spray dryer method. Increasing skim milk’s concentration had a significant effect (p<0.05) on proximate, chemical, and microbiological properties, except for total dissolved solids in the product. Increasing the concentration of skim milk enhanced solubility, total dissolved solids, yield, pH, total lactic acid bacteria, yeast, and microbial counts, while reducing moisture content, protein content, fat content, and titratable acidity. The addition of skim milk with the highest concentration produced a yield of 27.51%, caused by the drying factor with a spray dryer. It produced yeast of 7.43 log CFU/g and lactic acid bacteria of 5.17 log CFU/g, with lactic acid bacteria levels lower than the standard due to suboptimal drying and encapsulation processes. The best treatment in this study was the addition of 10% (w/v) skim milk.

Rabbits are easily adaptable and reproduce quickly, providing benefits to breeders. Kendal Regency is one of the areas in Central Java Province that has potential in the field of rabbit farming. One of the rabbit farming groups in Kendal Regency is the Aza Akmal Rabbit Farm, which develops New Zealand rabbits. The high number of rabbits is inversely proportional to the low market demand; thus, the marketing of rabbit meat is still limited to frozen carcasses. This is influenced by the lack of knowledge of breeders regarding the processing and marketing of rabbit meat products. The purpose of the community service activity was to provide education related to the importance of product innovation and how to process rabbit sausages to increase community income. The method used was direct skills training, and the level of preference was evaluated using a hedonic test on 25 panelists. The results of the activity were in the form of a brownish-white rabbit sausage product, with a distinctive aroma and taste of rabbit sausage, and a compact and chewy texture. The results of the hedonic test of the color parameters were quite liked, aroma liked, texture liked, taste liked, and overall liked. In conclusion, community service activities can add new knowledge related to processing rabbit sausages. The hedonic test results showed that the panelists liked the rabbit sausages, indicating their potential for development to improve the community's economy.
