Abstract

This study aimed to analyze the effect of using wheat flour, breadfruit flour, and a combination of both, as well as the addition of carrots, on the quality of chicken nuggets. This study was conducted in two experimental stages using a Completely Randomized Design (CRD). Stage I used a 3x4 factorial RAL pattern with 3 repetitions. Factor A (Type of flour) consisted of wheat flour (X), a mixture of wheat flour and breadfruit flour (Y), and breadfruit flour (Z). Factor B (flour level) included 7.5%; 15%; 22.5%; and 30%. Stage II used a single-factor RAL with four treatments of carrot addition levels (P): 7.5%; 15%; 22.5%; and 30%, each repeated three times. The research parameters included cooking loss, meat shear force, and water holding capacity (stage I) as well as cooking loss, meat shear force, water holding capacity, dietary fiber, and β-carotene (stage II). Phase I research showed that the type and level of flour had a very significant effect (P<0.05) on water holding capacity and meat shear force. The use of 15% breadfruit flour and 30% carrot gave the best results in cooking loss (5.00%), β-carotene (245.13 µg/100g), and dietary fiber (5.82%). Keywords: Nuggets, breadfruit flour, carrots, physicochemical properties

Abstract

One of the weaknesses of the livestock sector management in Indonesia, particularly in Sinjai Regency, is the lack of population data. The available data so far mostly consists of general beef cattle population data without clear population structure details. To understand the development of the beef cattle population, a forecasting approach based on various beef cattle population data in Sinjai Regency is necessary. This study aims to analyze the structure and dynamics of the beef cattle population and calculate the predicted population development of beef cattle in Sinjai Regency. This research uses a case study method with purposive location selection. The beef cattle population dynamics data were processed using the time series forecasting method, specifically exponential smoothing with α = 0.9, based on annual data over 10 years from 2015 to 2024. The results show that if the data behavior remains the same as the actual data from the past 10 years, the overall structure of the beef cattle population in Sinjai Regency consists of fewer male cattle compared to female cattle. The forecasted beef cattle population in Sinjai Regency for 2025–2034 varies and tends to increase year by year, except for a decline in population in 2033 due to technical constraints in the development of beef cattle by the community in the field. Keywords: Forecasting, Population, Beef Cattle, Sinjai Regency.

Abstract

Semen quality is influenced by the frequency of ejaculation, which is significant to semen characteristics. The purpose of this study was to analyze the effect of ejaculation frequency on the quality of fresh Bali cattle semen, which includes volume, motility, and concentration of spermatozoa at the AI Center Pucak Maros. This study used secondary data from production records (recording) derived from 5 Bali cattle males, with a frequency of ejaculation of 2 times. The results showed that the frequency of ejaculation was statistically significantly different (P<0.05) in semen volume in males 11442 and 11434; the percentage of motility was significantly different (P<0.05) in male 11539; and the concentration of spermatozoa was significantly different (P<0.05) in males 11442, 11434, and 11539. The correlation coefficients for the three quality parameters showed negative correlations between semen volume and motility (R=-0.531) and concentration (R=-0.414), whereas motility and concentration were positively correlated (R=0.740). In conclusion, the second ejaculation has an impact on increasing semen volume but will reduce the percentage of motility and concentration of spermatozoa. Keywords: ejaculation frequency, Balinese cattle, volume, motility, concentration
