Goat is considered an attractive business for small-scale farming in developing countries and less-favored areas due to their well-adapted to the grazing on poor marginal lands . Small ruminants like sheep and goats are important for a larger part of the Indonesian rural population. The major breeds of goats found in Indonesia are the Kacang and Etawah goats. The concentration areas for raising Ettawa Crossbred goats are upland regions, such as Kulon Progo and Sleman Yogyakarta. Besides producing animal products, they also provide manure to maintain soil fertility . Livestock manure is an important resource for food and feeds production because it supplies measure nutrients such as nitrogen (N), phosphorus (P), and potassium (K) . Ruminant manure is a valuable resource as a soil fertilizer, providing both macro, and micronutrients required for the plant growth, and is a low cost alternative to mineral fertilizer . Farmers use sheep and goat manure as fertilizer for their fruit trees and paddy fields . Ettawa goat manure and urine have a good potential for rice farming . Adult goats in Turi Sleman Regency produced 1 kg manure per day . In Indonesia, the goats on small farms are generally kept in wooden housing with slatted flooring and raised above the ground, so goat manure can be collected .
2. Material and Method
The location selected in Kulonprogo district which is a center for the breeding production of Ettawa crossbred goats in Yogyakarta. Collecting data census farmers comes from 65 respondents in the hamlet Tegalsari, Village Ngargosari, Samigaluh, and Kulonprogo. Descriptive analysis was used to explain the characteristics of the respondents and obtained from the tabulation of questionnaires.
Binomial Logistic regression (logit) was in use to seek the determinant factors that influences to the choice of farmers ready implemented waste treatment or not. The logit model is a function of cumulative probability logistic, which is formulated as follows:
For ease of exposition, it can be written as
where Zi = α +βXi
Equation (2) was the cumulative logistic distribution function. In that equation, Zi ranges from - to + , Pi ranges between 0 and 1 and that Pi is non linearity related to Zi (in Xi and the β's).
If Pi is probability of a farmer ready to implementation waste treatment, then (1-Pi) is the probability of waste treatment not ready to implementation where,
Therefore, it can be written as:
Further Pi/(1-Pi) is the Odds Ratio or the ratio of the probability that a farmer will ready to implementation waste treatment.
In the form the natural log of the Odds Ratio, namely
(5) e = 2.71828
In the form equation was:
P = choice farmers to implementation waste treatment
α = intercept
β1 ........β5 = regression coefficient
X1 = age (year)
X2 = formal education (score)
D1 = dummy of non formal education
1 = trainee
0 = not trainee
X3 = experience (year)
X4 = member of household (person)
X5 = goat ownership (goat)
µ = stochastic disturbance term
Because the model was nonlinear, so that the model was tested using Maximum Likelihood Estimation (MLE) test. It means to get the value of Likelihood Ratio Index (LRI) which should be equal to R-squared in OLS regression, Likelihood Ratio (LR) test which should be equal to F-test in OLS regression, and Wald test which should be equal to t-test in OLS regression [9,10].
3. Results and Discussion
Based on the research results, judging from the characteristic of respondents including productive farmers age (48.75 yr) and business experience has been effort hereditary (22.63 yr). The mean level of similar elementary school education (51.00 %) in particular is relating to the low implementation of waste treatment technologies (11.27 %). The average family size was 3.63 1.50 of people. Farmers involved their family members in participating in managing the farm business .
Table 2 shows the average ownership of 4.88 goats per farmers or 0.55 AU per farmers. The highest of parent doe showed heterogeneity livestock awake. While waiting for a good price for selling, farmers have the opportunity to obtain additional products such as kids and manure. Kids with 3 mo to 4 mo is ready for sale IDR 1 770 000 per goat for males and females IDR 1 416 155 per goat. Utilization of manure for plants was 89.00 % and the remaining 11 % for fertilizer plants and sold. In Kulonprogro potential crops being developed are plantation crop cloves (Syzygium aromaticum (L.) Merrill & Perry), coffee (Coffea L.), tea (Camellia sinensis (L.) Kuntze), and coconut (Cocos nucifera L.). A total of 70.80 % of farmers did not do a manure treatment through fermentation. This concurs with the statement that farmers knowledge on handling and processing of goat manure is still lacking . Farmers do not calculate the intangible benefits of goat manure to provide added value to the family income. In Turi Sleman Regency 10.20 % of farmers had been processing the manure and selling the compost . In this area, the utilization of goat manure is mainly to support fruit production, especially for Salak Pondoh [(Salacca zalacca (Gaertn.) Voss cultivar Pondoh] because these fruits are the main agriculture products which require goat manure as the fertilizer.
The results of the binary logistic regression model analysis showed that goat ownership had a significant positive effect (P 0.05) to the choice of farmers in implementing waste treatment. The value of the Odds Ratio showed probability goat ownership increased by 1.5778 times higher than in those who did not implement waste treatment. Similarly, a number of family and age significantly (P 0.10).
Based on the results of research on the benefits of understanding farmers goat manure is still lacking. The implication of this research is the need for socialization understanding of the importance of manure treatment to improve the intangible benefits at the household of farmers. Farmers groups should be facilitated to cooperate with the Department of Agriculture or Animal Husbandry, education institutions, and corporate Research and Development of Agriculture. Forms of cooperation include education about processing technology goat manure into compost and liquid fertilizer, livestock procurement assistance, and marketing of fertilizers.
