Abstract:
The objectives of this research was to develop an alternative approach to calculate the cows need to produce the condition of beef self-sufficiency in the West Papua Province. The collected data involved the secondaries i.e. number of cattle slaughter and people population; and the primaries data i.e. number of bull < 1 year old, 1-2 years old, and > 2 years old and number of cows of the farmer household. Documenting of secondaries data, interviewing use quetionare, and field observation were used as the methods of data collecting in this study. Sources of data in this research were farmer household. Data were analyzed by using the mathematics and econometrics equation models, specially the Partial Adjustment Model (PAM) and Ordinary Least Sqaure (OLS) i.e. simple and multiple linear regression. The population of this study was farmers with the sample number of 189 respondens. Manokwari was choosen as the sample area of this study. The results of this study showed that we could develop an approach to estimate the number of invested cows in order reaching beef self-sufficiency . This approach was consisted of three (3) steps of (a) to estimate number of consumption of beef (in animal unit) as a function of people population in the region, (b) to develop an estimator equation of the variables of number of cows and their produced bulls, (c) to use the developed estimator equation of the second step to calculate the number of need invested of cows to reach the condition of beef self-sufficency in the study area.
