Abstract

THE EFFECTS OF PALM JUICE VINEGAR TOWARDS THE ORGANOLEPTICS OF MUSCOVY DUCK MEAT (Chairina moschata). People in North Sulawesi are continued to develop duck farming. Most of them run their farm with traditional system. The species of duck developed in North Sulawesi of Chairina moschata is called Muscovy duck. Special treatments were applied in cook processing of duck meat especially to eliminate stink and tough texture. Palm juice vinegar containing acetic acid has many roles when it was added in foods stuffs including duck’s meat. The aim of this research was to evaluate the organoleptic taste of duck meat immersed in palm juice vinegar. The objects of this research were breast part of duck meat immersed and in juice vinegar and stored during 4, 8 and 12 days. This research used completely randomized design involving 4 treatments with 40 untrained panelists as replication. Observed variables were colors, flavors, meat tastes and meat tenderness. Data was analyzed using ANOVA and Duncan Multiple Range Test (DMRT) for further significant treatments. The results showed that immersion treatment of duck meat in palm juice vinegar stored during 4, 8 and 12 days gave significant effects (P<0.01) to organoleptic of duck meat. Further test with DMRT showed that immersion of duck meat in 12 days palm juice vinegar can be accepted by the panelists as the best treatment.   Keywords: Organoleptic test, duck meat, palm juice vinegar

Abstract

THE EFFECT OF THE ADDITION OF HONEY TO THE PH VALUE, SYNERESIS AND TOTAL LACTIC ACID BACTERIA OF SINBIOTIK YOGURT. This study was conducted to determine whether honey gives an influence on the pH value, syneresis and LAB of synbiotic yogurt. In this study, the main ingredients used were 5 liters UHT milk, Skim milk 400 g, honey 240 mL, Lactobacillus acidophillus bacteria, Streptococcus thermophilus and Lactobacillus bulgaricus, aqudes, MRS Media (Man Rogosa Sharpe Medium). Equipment used during the study included autoclave, pH meter, Erlenmeyer, test tube, pipette, thermometer, analytical scale, petri dishe, desiccator, blender, oven, incubator, micro pipette, burette, spritus lamp, goblet, refrigerator. This research was carried out on January 7 2019 until March 12 2019 at the Laboratory of Animal Product Technology Faculty of Animal Husbandry, Sam Ratulangi University, Manado. The experimental design used in this study was a Completely Randomized Design (CRD) method with treatments 5 and 4 replications. The variables analyzed in this study are pH, Sinereis and Total LAB. The data obtained were analyzed using ANOVA, there were significant differences between the treatments followed by the BNJ test. The results of this study indicate that the treatments of P0(0%), P1(3%), P2(6%), P3(9%) and P4(12%) have a very significant effect (P <0.01) on the pH value, Sineresis and Total LAB. Based on the results and discussion that the use of honey by 12% can increase the value and produce the best pH, syneresis and total lactic acid bacteria in synbiotic yogurt.Keywords: Sinbiotic Yogurt, Honey, pH, Sinresis, LAB.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui kualitas kimia susu sapi perah yang ada di UPT Pembibitan Ternak dan Hijauan Pakan Ternak Rembangan Kabupaten Jember yang meliputi kadar lemak, kadar protein, bahan kering tanpa lemak, dan pH.. Penelitian ini dilakukan dengan mengambil susu sampel sapi perah setiap bulan selama tiga bulan, mulai dari bulan april sampai bulan juni tahun 2023. Hasil penelitian menunjukkan bahwa kandungan lemak dan bahan kering tanpa lemak yang ada di UPT Pembibitan Ternak dan Hijauan Pakan Ternak Rembangan berkisar antara 7,63%-8,29%, kadar lemak susu 3,69%-4,13%. Kedua variabel ini belum memenuhi syarat berdasarkan SNI. Sementara protein susu dengan nilai 2,90%-3,42% dan pH susu 6,3- 6,5 telah memenuhi syarat berdasarkan SNI. Berdasarkan hasil penelitian dapat disimpulkan bahwa kualitas kimia susu sapi perah yang ada di UPT Pembibitan Ternak dan Hijauan Pakan Ternak Rembangan perlu ditingkatkan untuk kandungan bahan kering tanpa lemak dan kadar lemak. Kata kunci: Kualitas kimia, Susu, Sapi Perah.
