The potential of Sensi-1 Agrinak and KUB crossbred so-called SENKUB chicken as dual-purpose chicken can be increased by selecting hatching egg weights to get DOC with good quality. The study was conducted to evaluate the grades of hatching eggs of SENKUB chicken on hatching and production performances. The complete randomized design was applied in this experiment with 3 treatments. The treatments are the grades of hatching egg (small 36-40 g, medium 41-45 g, and large 46-50 g). The hatching process used two stages hatching machine. All DOCs were selected according to the Indonesia National Standard (SNI). The selected DOCs were raised in different pens to evaluate the production performances. The hatching showed that the large eggs have significantly the highest fertility, hatchability, hatching weight, and salable chick but the lowest weight loss. Embryo mortality was the same between different hatching egg grades. The best-weight DOC was obtained from medium and large hatching eggs. The hatching egg grades do not significantly affect the production performances of the hatched chicken. However, the chickens with small and large hatching eggs resulted in better production performance.

Butterfly pea (Clitoria ternatea L.) is leguminous species that contain high nutritional values. This study aimed to determine the effect of the rate of urea fertilizer and harvest age on the productivity of butterfly pea forage. This research used a split-plot design consisting of urea rates (0, 100, and 200 kg/ha) and harvest ages (30,45, and 60 days after planting or DAP) with three replications. The variables observed were morphological growth (plant height, stem diameter, number of leaves, and number of branches), and productivity of forage biomass (fresh weight, dry weight, and crude protein). The data obtained were analyzed using ANOVA and the means were separated by using Duncan's Multiple Range Test (DMRT). The interaction between fertilizer rates and harvest ages was shown (p<0.05) on stem diameter, number of leaves, number of branches, and fresh weight of butterfly pea. The increased rates of fertilizer and harvest ages significantly affected (p<0.05) in the morphological growth and productivity of butterfly pea biomass. The application of urea fertilizer increased plant length from 10.59 to 17.16%, stem diameter from 12.12 to 24.24%, number of leaves from 15.40 to 28.20%, and number of branches from 81.82 to 190.91% compared to control. It was concluded that the morphological growth and productivity of forage biomass increased with fertilizer rates and harvest ages. Treatment of 200 kg/ha urea and harvest age of 60 DAP produced the highest morphological and productivity.

The purpose of this study was to examine the economic valuation of Sentul chicken to determine the amount of incentive farmers should receive. A survey method has been conducted as the research methodology.The research location was determined purposively, namely in accordance with the research objectives, on the basis of several considerations, the location where the research was located was the Sentul chicken development center where there were active farmer groups. A total of 39 farmers who had a minimum of 100 Sentul chickens/year were censused to become respondents. Data collection was carried out in May - August 2022. The data were analyzed by the contingent valuation method (CVM) using the willingness to accept (WTA) approach in the bidding game. The WTA value sought is the Total WTA (TWTA) and Mean WTA (EWTA) which are converted into incentive values for farmers. Multiple regression analysis has been applied to investigate any significant factors that affected the WTA value. The study results show an estimated total WTA value of IDR 191,220,000 per year and an estimated WTA value of IDR 178,974.36 per chicken per year. Education, experience, land area, income, livestock orientation, and pride are WTA factors that impact farmers, as income (0,024) and pride (0,000) become the most influential factors. Efforts to conserve Sentul chickens can be realized using the incentives indicated by a high WTA value. Therefore, policy makers can conserve Sentul chickens using an incentive approach

In this study, the elasticity of production costs to broiler business income with the partnership pattern in Banyumas regency and production costs and broiler business income with open and closed house systems were examined. The survey approach was used to conduct the research. As the research site, Banyumas regency, one of the hubs for broiler farming in Central Java, was deliberately chosen. Commercial broiler farmers were categorized according to their housing system when choosing the respondents, and 31 farmers used the open housing system, whereas 30 farmers used the closed housing system. The elasticity of production costs to revenue was examined using multiple linear regression while production costs and profits were assessed financially. According to the findings, commercial broiler farmers made an average of IDR 3,626,578 and IDR 4,896,844 each month for 1000 birds in open and closed houses, respectively. The price of DOC, the depreciation of housing, and the depreciation of the farmers' equipment all have a big impact on their revenue. This study's conclusion is that by lowering broiler mortality and making the best use of housing and equipment, farmers may increase their profitability.
