Bung Hatta University’s PKM team (UBH) consisting of Yusra (FPIK lecturer), Maria Ulfah (Chemical Engineering) and Dessi Mufti (Industrial Engineering) succeeded in producing fish waste processing innovations that were able to produce value-added products based on zero waste.
The birth of this innovation, which was supported by Sindy Gemaeka Putri, Andika Saputra and Richi Erlini (all three alumni from FPIK UBH), started with the role of the Fish Processing Unit in the Pasia Nan Tigo Fisheries Processing Center (SP3N) not being maximized.
Where, dominant anchovy processing and is traditional. The lack of public knowledge about processing fishery products makes people only focus on fish.
When the fish caught by fishermen are abundant, sometimes the fish are left alone, not processed. Likewise, the ashes or the remains of broken dried fish are piled up in sacks in the warehouse room. So that many fish are eaten by rodents, even if the price is very cheap.
“This PKM activity begins with socialization of waste, B3 waste, regulations on fish processing wastewater quality standards, the impact of waste disposed of around the processing site, the need for a waste treatment process, the importance of applying the concept of clean products (clean production), and the principle of zero waste in the processing process. fish processing,” said Yusra.
Then, training was conducted on the manufacture of liquid organic fertilizer (POC), fish meal, petis and fish meatballs. According to Yusra, many processors only work as housewives so they are less productive.
The PKM team itself uses fish washing wastewater which is usually disposed of as liquid organic fertilizer and applied to spinach and cesim vegetables. Fish that have less economic value are processed into fish meal, fish paste and fish meatballs by going through a series of certain processes.
The liquid organic fertilizer produced can also be used to grow fish, fish processing women on a household scale, such as planting vegetables in the yard such as spinach, cesim and pakcoy so that they can anticipate the use of pesticides and chemical fertilizers.
In addition to self-consumption, the resulting vegetable crops can also be sold so as to improve the household economy, especially when fish production declines. This activity received a very positive response from fish processors, fishery instructors and the Head of the Pasia Nan Tigo Fisheries Processing Center (SP3N). (adt)
