Abstract

The study aimed to obtain a comprehensive description of the chemical quality decrease of milk adulterated with water from different sources. Experimental research was carried out at the Dairy Production Laboratory, with the main material being milk from the Experimental Farm, Faculty of Animal Science, Unsoed. The study used a completely randomized design (CRD)-factorial. Factor A was three types of milk (no adulterated milk (NA), adulterated by farm water (AFW), and adulterated by house water (AHW)). Factor B was six times of storage (0; 4; 8; 12; 16; 20 hours). There were 18 treatments, each repeated three times. Thus, there were 54 units. Milk quality was observed at controlled room temperature, namely the average temperature of Purwokerto City (300C) in the incubator. Data were analyzed for variance and further tested for linear regression. The analysis of variance showed that the interaction between the type of adulteration and storage time had a very significant effect (P

Abstract

ABSTRAKPenelitian inibertujuan untuk menganalisis faktor-faktor yang mempengaruhi produksi susu. Metode penelitian menggunakan metode survey, pengambilan data dilakukan secara purposive sampling dengan kriteria sapi perah yang sudah laktasi dan melakukan sampling pada 47 responden anggota KPBS Pangalengan, Bandung. Variabel yang dianalisa adalah produksi susu sebagai variabel dependen (Y), dan variabel independen (X) meliputi pakan hijauan, pakan konsentrat, masa laktasi, masa kering, umur sapi, umur pertama estrus, umur petama beranak, days open dan service per conception. Analisis data dilakukan secara deskriptif dan analisis statistik mengunakan persamaan regresi linier berganda. Hasil penelitian menunjukan bahwa faktor-faktor yang mempengaruhi produksi susu yaitu faktor X1, X2, X3, X4, X5, X6, X7, X8 dan X9 secara bersama-sama berpengaruh nyata (P<0,05) terhadap produksi susu. Kinerja produksi susu dapat dipengaruhi olehfaktor-faktor independen sebesar 60,1% sedangkan 39,9% disebabkan oleh faktor lain diluar penelitian. Dapat disimpulkan bahwa faktor yang mempunyai pengaruh sangat kuat terhadap produksi susu adalah masa laktasi sedangkan faktor yang mempunyai pengaruh yang rendah adalah masa kering. Kata Kunci: Sapi Friesian Holstein, produksi susu, Masa Laktasi, masa kering KPBS PangalenganFactors Affecting the Production of Friesian Holstein Dairy Cow at KPBS Pangalengan, Bandung RegencyABSTRACT This study aims to analyze the factors that affect milk production. The research method uses a survey method, data collection is carried out by purposive sampling with the criteria of lactating dairy cows and sampling on 47 respondents from KPBS Pangalengan, Bandung. The variables analyzed were milk production as the dependent variable (Y), and the independent variable (X) included forage feed, concentrate feed, lactation period, dry period, age of cows, age at first estrus, age at first calving, days open and service per conception. Data analysis was carried out descriptively and statistical analysis using multiple linear regression equations. The results showed that the factors that affect milk production, namely factors X1, X2, X3, X4, X5, X6, X7, X8, and X9 together had a significant effect (p<0.05) on milk production. Milk production performance can be influenced by independent factors by 60.1% while 39.9% is caused by other factors outside the study. It can be concluded that the factor that has a very strong influence on milk production is the lactation period, while the factor that has a low influence is the dry period.
