Dr. Ir. Endang Purbowati, M.P. (Faculty of Animal and Agricultural Sciences Undip) presented her scientific material entitled “Fattening Young Sheep Based on Leftover Agro-industry Products to Produce Efficient and Environmentally Friendly Low-Fat Meat” in the Scientific Paper Presentation event for Diponegoro University prospective professors held by the Undip Board of Professors, Tuesday (18/4).
“This paper reviews the strategies for utilizing leftover agricultural and agro-industrial products in Indonesia in an effort to produce low-fat lamb meat efficiently and environmentally friendly. The purpose of the presentation of this paper is to provide guidance or recommendations on fattening young sheep based on leftover feed from agriculture and agro-industry in Indonesia to produce efficient and environmentally friendly low-fat meat,” she said.
Furthermore, she conveyed that the main factors that affect meat quality are livestock factors (race, age, and slaughter weight), and feed factors (type of feed, nutrient content, and the balance of fibrous and concentrated feed). Fattening sheep after weaning (3-5 months old) or known as early fattening, in terms of rearing time is more efficient around 4-6 months and more economical because within 1 (one) year can be harvested 2 (two) times, produce soft meat soft with low fat (lean meat). Increasing the concentration level in fattening sheep by feedlot can increase daily body weight gain, improve feed conversion and increase slaughter weight, carcass percentage and meat bone ratio. The use of rice straw fibrous feed in feedlot fattening resulted in lower carcass fat (16.39% vs 22.17%) than elephant grass.
The nutrient content of feed for fattening young sheep with complete feed in the form of pellets to produce low-fat meat is 15% crude protein (PK) and 60% total digestible nutrients (TDN). Thin tail lamb (DET) which is slaughtered at a weight of 20 kg can be categorized into fat class 1, because it has a percentage of 14% fat, 68% meat and 18% bone. Young DET fattening produces meat with 46.56% saturated fatty acids (SFA) and 53.44% unsaturated fatty acids consisting of 49.36% mono unsaturated fatty acids (MUFA) and 4.08% poly unsaturated fatty acids (PUFAs). Replacing elephant grass fiber sources with fibrous feed from agro-industrial waste does not exacerbate the environmental impact. Even the use of peanut shell fibrous feed resulted in methane emissions per gram of body weight gain 12.5% lower than elephant grass fibrous feed.
The scientific work of Ro’fah Setyowati, S.H., M.H., Ph.D. (Faculty of Law Undip) discussed the “Protection of the Spiritual Rights of Halal Tourism Consumers through Strengthening Sharia Compliance.” The implementation of consumer protection is basically an effort to realize the function of law in providing justice, legal certainty and benefits for all parties, including Muslim consumers who have special characteristics.
“Consumers’ spiritual rights are a guarantee for the implementation of legal principles related to spiritual aspects. If related to the context of halal tourism, the spiritual rights for Muslim consumers are related to the application of sharia principles. Thus, the halal status of various elements, facilities and services in the implementation of halal tourism is absolutely necessary. In this case, the business actor has an obligation to provide it, according to his offer to consumers,” she explained.
“Similarly, the State which is run by the Government, also has the same obligation in implementing consumer protection. The obligation to fulfill spiritual rights is known as sharia compliance. When a business entity has declared it as a sharia-based institution, the institution has the obligation to run it properly. Theoretically it has been proven that the value or quality of sharia compliance in a business institution has an impact on increasing consumer confidence, and in turn has an effect on increasing business volume and profits. However, the problem is that in the halal tourism sector, there is no law that forms the basis of clear and integrated consumer spiritual rights,” she concluded. (Lin – Public Relations)
