UNAIR NEWS “ Increasing national milk consumption can not be met by domestic milk production.This means that demand cannot be fulfilled by domestic production.This is one of the challenges for the government as well as the livestock industry.
This is partly due to the state of dairy farming in this country that has not met the standard criteria of livestock farming, in addition to the problem of erratic season, especially the dry season where temperature ranges from 18 to 38oÌý°ä.
This temperature causes heat stress to the dairy cows.For example Fries Holstein cows which then reduces the productivity of dairy cows.
Based on the problem, Zulfan Adzhar, Abi Farhan Ramadhan and Iollanstallza Simangunsong, students of Faculty of Veterinary Medicine (FKH) successfully made a technological breakthrough throughanimal welfarebasedaerial foggingsystemthat can support milk productivity in Indonesia.
Under the guidance of Hana Eliyani, M.Kes., Drh., A lecturer of FKH UNAIR, the students™ report entitled ”Animal Welfare Based Aerial Fogging System on Dairy Farming to Support Milk Productivity in Indonesia”, passed the Ministry of Research, Technology and Higher Education selection and obtained development fund in PKM 2018. The three students™ creative work are included in Invention category (PKM-KC).
Explained by Zulfan Adzhar as leader of this PKM-KC team, the working principle of thisaerial foggingsystemis to utilize the fog collected in jerrycans containing 1 liter of 98% alcohol.This alcohol works as additional cooling agent to minimize ozone damage by using evaporation principle.
Thisaerial foggingis used as an evaporator through arrangement onControl Aerial Systemwith certain time duration.Foggeractivationcan be adjusted bytimer or manually with valve rotation or by settingcomputer control systemthat has been installed room temperature sensor and compare it withstressingtemperature ofdairy cows.
“When the temperature sensors detect room temperature exceeds the standarddairyheat stress temperature, themicrocontrollerwill be active and thewater pumpwill work to channelmixing ofwater and 95% alcohol intoaerial spraying,” said Zulfan.
“Sothe mix ofwater and alcohol will be sprayed to the cage area until the temperature of the cage adjusted with the standard cow heat stress that has been previouslyset, so the level ofcowstressis expected to be reduced and the milk production is improved,” added Zulfan Adzhar.(*)
