The Effectiveness of Curcuma (Curcuma xanthorriza Roxb.) Addition in the Feed toward Super Kampong Chicken Performances

Research purposes were to analyze the effect of curcuma in the feed toward the performances of kampong super chicken. The research materials used were 100 DOC (Day Old Chick) super kampong chicken The variables was: body weight gain, body weight, consumption, feed conversion ratio, carcass weight, abdominal fat weight, meat fat content, meat protein content, fat digestibility, crude fiber digestibility, protein biological value, and nitrogen retention. The experimental design in this study used a Completely Randomized Design (CRD). The treatments as follows: T0: Feed without curcuma 0.0 % (as control), T1: Feed with curcuma 0.33 %, T2: Feed with curcuma 0.67 % and T3: Feed with curcuma 1.00 % with five replications. The results of research, giving curcuma as feed additive had a significant effect on body weight gain and final body weight of kampong super chicken but it had no significant effect on feed consumption, feed conversion ratio, carcass weight, abdominal fat weight, fat content meat, meat protein content, fat digestibility, crude fiber digestibility, protein biological value and nitrogen retention of kampong super chicken. There were no significant differences between T0 and T1, but it was different from T2 and T3, and T2 showed no difference with T3 on body weight gain and final body weight. The best treatment in this study was T0 and T1, namely the addition of curcuma 0 % and 0.33 %. From the conclusion, we suggest using 0.33 % curcuma as feed additive in the super kampong chicken feed for body weight gain and final body weigh

Bird Diversity, Abundance, and Evenness Rates in Ecotone Area of Sutan Syarif Hasyim Forest Park, Riau, Indonesia

Ecotone – an area where two environments of different composition and structure meet due to land conversion – is prone to habitat loss and biodiversity devaluation as a result of fragmentation. Responsive to change, birds represent one of the common animals of all habitat types since their diversity and abundance are able to reflect ecological tendencies in different biodiversity. This study was aimed to analyze the diversity, abundance, and evenness of birds as well as determine their density and frequency in the ecotone area of Sutan Syarif Hasyim Forest Park, Riau, Indonesia. Six sections of the study area (natural forest-and-shrubbery, natural forest-and-palm oil plantation, natural forest-and-lake, shrubbery-and-palm oil plantation, shrubbery-and-lake, and palm oil plantation-and-lake) were observed by employing Line Intercept Transect. 1 182 individuals of 59 bird species were reported, with Pycnonotusaurigaster (Vieillot, 1818) as the dominant one. The total diversity index of 3.75, abundance 8.2 and evenness 0.92 were evident to high density and frequency of birds in the area

Stability of the Broiler Antibody Under Heat Stress Using Dry Rice

This study examines the impact of using dry rice, characterized by low calories and high resistant starch content, on broiler performance under heat stress conditions in Indonesia. Broilers face challenges related to stress, particularly heat stress, which can compromise their immunity. The research investigates the potential of resistant starch in dry rice to enhance broiler digestion performance and immunity. The experiment, conducted at Zakiyah Farm and the Laboratory of the Wates Veterinary Center, Yogyakarta, involved three treatments (T1, T2, and T3) with five replications each. Observed variables included water consumption, carcass weight, Packed Cell Volume (PCV), bursa fabricius weight, and Hi-Test Nd antibody levels. Results showed no significant impact on water consumption, carcass weight, and PCV across all treatments. However, a decrease in bursa weight in T1 and T3 indicated an increased level of stress. The lowest seropositive Hi-Test Nd values in T1 and T3 suggested that the use of dry rice through the sowing method might alleviate heat stress on broilers. In conclusion, this research emphasizes the potential of dry rice to maintain the stability of broiler antibodies under heat stress conditions, emphasizing the need for further exploration of alternative dietary components

Assessment of soil chemical properties for monitoring and maintenance of soil fertility in Probolinggo, Indonesia

Soil is paramount to sustaining living in biomass production, water quality control, climatic mitigation, and biodiversity endurance. Closely associated with sustainable agriculture, it degrades soil in the long run, robbing the soil of its production capacity and food-generating ability. In Probolinggo, a regency in Indonesia, intensifying the use of chemical fertilizers and pesticides yet a declining trend in yield production was discovered. This research analyzed the acid, nitrogen, organic carbon, and nutrients focusing on phosphor, potassium, iron, and manganese contents. Organic carbon/nitrogen ratio, soil organic compound rate, and cation exchange capacity were also discussed in order to illustrate the correlations among chemical substances and their roles in soil and plant maintenance. While such a study has yet to be performed in Probolinggo, the results should show the degree of land deterioration and future attempts at damage control and correction open to facilitate. Employing a simple random method, soil and plant samples were collected from 18 villages in six districts and their chemical contents were compared to the standard set in Government Regulations No 150/2000. The results showed low N-total, P-Bray, P-Olsen, K, C-Organic, and C/N ratio availabilities at 0.18, 13.88, 14.41, 0.37, 1.36, and 7.38 respectively, contrasted to high rates on pH (5.94), Fe (153.46 mg kg–1) and Mn (37.96 mg kg–1). Biomass production is conclusively imperative to fix the land composition and meet the plant nutrient requirements through an organic approach; fertilizers from digester biogas are therefore recommended. This action requires field agricultural advisors to raise awareness of sustainable agriculture
