Blockchain Chicken Farm: And Other Stories of Tech in China’s Countryside, written by Xiaowei Wang

Abstract In this study, a novel feather-degrading bacteria B. amyloliquefaciens KB1 was isolated from chicken farm bed (CFB), identified by morphological, physico-biochemical tests followed by 16s rDNA analysis. Among observed isolates, bacterial isolate (KB1) showed the highest degree of feather degradation (74.78 ± 2.94 %) and total soluble protein (205 ± 0.03 mg/ g). Using the same species of bacteria, the optimum fermentation condition was found at 40 oC, pH 9, and 1 % (w/v) feather concentration that produced 260 mg/ g of soluble protein and 86.16 % feather degradation using response surface methodology in a Box-Behnken design space. The obtained hydrolysates exhibited bioactive properties. The amino acid profile showed the increase in concentration of essential amino acid compared with feather meal broth. The selection of safe screening source of this new bacteria in CFB produced hydrolysates with enhanced bioactivity applicable for food, feed, and cosmetic applications along with environmental remediation.

Chicken broiler is the main commodities and largest in Indonesia, where Kampar district into production centre in the province of Riau. According to the company's partners, breeder who partnered with the pattern contract farming hasn't been able to combine the use of livestock production facilities as well as labor. This resulted in not maximizing the profits obtained by breeders. The purpose of the research was to analyze broiler chicken farming and analyze the efficiency of broiler chicken production. Analytical method used is the analysis method of broiler chicken flocks and the DEA method. Respondents needed is 40 farmers who have partnered with the contract farming pattern. The results showed that the production costs of Rp.180.031.229 /period, revenue Rp.203.573.865/period, so that the profit amounting to Rp 23.542.636/period with R/C ratio of 1.13. The results of the efficiency analysis show that inefficient farmers are more numerous than those who have been efficient. It showed breeders hasn't been able to use the minimum input produce output that is optimal and maximum profit.

Abstract The production of local chickens in Indonesia is determined by the availability of high-quality local chicken stocks. However, information on local chicken performance is limited, therefore, this study aims to determine the live weight performance of three local Indonesian chicken namely Merawang, Murung Panggang, and KUB in the starter phase. The study was conducted at chicken farm located in Semanu Gunung Kidul, Yogyakarta. Meanwhile, the live weight data were collected at the starter phase (0, 2, and 4 weeks. The samples consisted of 196 Merawang, 157 Murung Panggang, and 416 KUB chickens reared in a battery cage in a closed house under similar conditions. Furthermore, the live weight performance data were analyzed using analysis of variance (ANOVA). As a result, the Merawang chicken had the highest live weight (P<0.05) at the day-old chick (DOC) age. At the same age, no significant difference was detected between the KUB and Murung Panggang chicken (P>0.05). However, the live weight of Murung Panggang was significantly higher at 2 and 4 weeks compared to others (P< 0.05). Therefore, it was concluded that there are variations in the live weight of the three local chickens during the starter phase.

The Impact

Abstract: The number of boiler chicken farm located in the community felt starting to annoy people, especially the chicken farm located close to residential areas. Many people complained about the bad effects of the operations of the boiler chicken farm because there are many farmers who ignore the handling of waste of effort. The impact that can arise is the smell of chicken farms, the emergence of flies and fears spread of bird flu virus. The purpose of this study was to analyze the relationship between the sewage smell chicken farm on the incidence of psychosomatic symptoms in a residential community surrounding villages cage Sei Lembu Makmur 2014. The design of this study analytic observational, cross-sectional study approach. This research was conducted in the month of January to August 2014. The sample in this study that people around the cage which amounts to 43 respondents. Data was collected through questionnaires and a doctor's diagnosis. Data were analyzed using univariate and bivariate analysis were processed using the computerized system and Lambda test. The results showed that respondents ammonia contaminated and uncontaminated 21 people 22 people (51.2 %), which has a disturbing perception as many as 23 people (53.5 %) and did not interfere with 20 people (46.5 %) and respondents who had psychosomatic disorders is 13 people (30.2 %) and not psychosomatic 30 people (69.8%) .Based Lambda test showed that there was no relationship between the concentration of ammonia with psychosomatic disorders in settlements around the cage Sei Lembu Makmur (p = 1.000> 0.05) and there was no relationship between perception and psychosomatic disorders in the settlements around the cage Sei Lembu Makmur (p = 0.462> 0.05). For the people around the cage explain to the public that air pollution by ammonia due to the smell of the chicken coop with the highest ammonia concentration of 3.32 ppm which means no influence posed to human health.

Cross Sectional Design

Occupational diseases can be caused by several factors of work and environmental conditions of workers. Poor environmental conditions and worker behavior are some of the triggers for the emergence of dermatitis in workers. Contact dermatitis in chicken farm workers can be caused by exposure to chemicals from animal feed. The purpose of this study was to determine the factors that influence the occurrence of dermatitis in chicken farmworkers. This research is a quantitative study with a cross-sectional design. The population in this study was a total sample of 35 people. The results showed that there was no relationship between the use of personal protective equipment, working period, and personal hygiene with the appearance of symptoms of dermatitis in workers. However, this study found that workers who have worked for more than 12 months and practice good personal hygiene tend to avoid symptoms of dermatitis. This study provides a recommendation that the longer a person has worked, personal hygiene improvement needs to be done to avoid dermatitis.
