As a form of the chemistry study program to improve the quality of graduates, the Chemistry study program, FMIPA UNY, organizes teaching practitioner activities on campus. Practitioners teaching activities on this campus presented two resource persons, namely Ms. Simping Yuliatun, S.Si. MP from the Indonesian Sugar Plantation Research Center and Mr. Yanwar Achmad, S.Si. from PT. Echo Putra Buana.

In her presentation, Ms. Simping Yuliatun delivered a presentation on Carbohydrate Processing as Food Ingredients. This lecture activity must be followed by students taking Food Chemistry courses. Mrs. Yuliatun said that carbohydrates are found in food/feed ingredients, for example in livestock products, there are many parts that can be utilized, including: (1) in milk there is lactose, and (2) in meat there is glycogen which is stored in muscle tissue and in the liver. These products can then be processed and used as the main energy source in the human body.

On the other hand, Mr. Yanwar Achmad, S.Si. convey about B3 Waste Management. This activity is mandatory for all students taking B3 waste management courses. Mr. Yanwar said that hazardous and toxic materials are materials which due to their nature and or concentration and/or quantity either directly or indirectly can pollute funds or damage the environment or can endanger the environment, health, survival of humans and other living creatures. As for the definition of hazardous and toxic waste: the residue of a business and/or activity containing hazardous and/or toxic materials which due to their nature and/or concentration and/or amount, either directly or indirectly can pollute and/or damage the environment, and/or may endanger the environment, health, survival of humans and other living creatures. Therefore, this type of waste must be handled specifically which includes storage, collection, transportation, utilization, processing, destruction and landfilling of B3 waste.
