The Statistics Study Program UNY held a Mathematical Economics Practitioner Lecture by presenting Mrs. Jamila Lestyowati, S.E., M.Si as a guest speaker. He is a Lecturer at the Yogyakarta Financial Training Center, Ministry of Finance of the Republic of Indonesia. The Economics Mathematics course is one of the elective courses in the field of interest in Actuarial Science. In the odd semester of 2021/2022, Mrs. Rosita Kusumawati, M.Sc. taught the Mathematics of Economics course at the Statistics Study Program, UNY and Mr. Bayutama Isnaini, M.Sc. The Economics Mathematics Practitioner Lecture this time raises two topics, namely public economic policy (State Revenue and Expenditure Budget, APBN) which takes place on October 30th, 2021, as well as government policy and balance (case study of government spending) which takes place on November 6th, 2021. These two practitioner lecture meetings were held online which were attended by students of the UNY Statistics study program from various generations. At the first meeting, Mrs. Jamila Lestyowati, S.E., M.Si explained the functions and roles of the government in making policies on the economy and explained about the State Budget. Meanwhile, the balance between state revenues and spending was discussed at the second meeting.

In general, Mrs. Jamilah Lestyowati, S.E., M.Sc explained that the government in issuing policies really considers various aspects. This government policy direction is reflected in the state spending plan. In compiling this state expenditure plan, there was a cross of opinion between sectors (sectoral ego), of which many considerations the government needs to prioritize which sectors will be prioritized. This priority is the form of the government's vision and mission in each leadership period or also every year. Policy making related to the state expenditure plan needs to be prepared in advance rather than thinking about the origin of state revenue/income. If state spending is greater than state revenue, then this difference is called the APBN deficit. The government, through law, regulates the maximum threshold for a deficit that is allowed, so that the amount of state debt that is allowed each year is regulated by law. Therefore, to keep the deficit below the threshold, the government needs to issue policies in terms of state revenues and adjustments to state spending. The submission and implementation of the APBN is divided into several stages, namely planning, determination, implementation, and supervision. The Economics Mathematics Practitioner Lecture Program is expected to provide insight to students about government policies towards the economy.
