The Department of System and Industrial Engineering (DTSI) is one of the largest departments in ITS and has been successful in its efforts to develop its educational programs. This is reflected by the acquisition of three accreditations, namely national accreditation (BAN-PT) with A accreditation for Bachelor (S1) and Postgraduate (S2 and S3) programs and international accreditation (ABET and AUN-QA). DTSI is currently a pioneer who has received AUN-QA accreditation certificates in 2015 and is the only one in ITS that has been accredited by ABET in 2016. DTSI has more than 2000 alumni spread across various national and international industrial sectors, as well as about 200 new students a year.
