Lecture scheduling systems that made manually need longer time and should be made time after time (trial and error) because there are many constrains should be considered like: number of classes, number of lecturers, number of courses and number of students. Delay in publishing class schedule could cause disruption in the lecture process. As an effort to continuous improvement, designing lecture schedule system based on application or website which easy to use by user was very needed. This research aims to design lecture scheduling information systems based on website and android in Industrial Engineering Department, Islamic State University Sultan Syarif Kasim Riau. This research also measures system success rate by using User Acceptance Testing (UAT). The fnding reveals based on UAT analysis to the information system of lecture scheduling designed, as an average, the success rate was 85.1% from 100% success expected.

Lean construction (LC) presented innovative practices to maximize the production value and minimize the production waste during construction. The problem that frequently occurs in the project is delaying the schedule, leading to time and cost overrun. This research aims to eliminate waste that causes delay and inefficiency. Several LC techniques were carried out to improve the efficiency of this project, namely: Value Stream Mapping (VSM) to discover wastes and determine Process Efficiency Cycle (PCE); Waste Assessment Model (WAM) to identify the inter-relationship among wastes; Fishbone (Ishikawa) diagram analysis to get the root cause of the waste. Research results showed the three highest wastes: defect 14.06%, overproduction 21.44%, and the highest rank was unnecessary inventories 31.73%. After implementing LC techniques, the PCE increased from 72 % to 79%. The implication of this research is to provide recommendations to project stakeholders in running the building construction to avoid delay and inefficiency.

The development of autonomy University drives management innovation to increase the alternative sources of income with the purpose of the efficiency improvement and productivity of the institution. One of a management model that leads to increase productivity through cost reduction is Lean service. The implementation of Lean Higher Education Institution (LHEI) requires total involvement of organization maneuver, including social culture, infrastructure, and leadership support. Therefore, the readiness of the institution in welcoming Lean concepts becomes significant. This article tried to develop a prototype of an intelligent performance measurement tool by analyzing the readiness indicators using the Analytical Hierarchy Process (AHP) method. This tool provided the classification of organizational readiness into five performances level. The measurement performed as a Decision Support System (DSS) to recommend University management level in making a decision and correcting action towards the optimal execution of Lean service. As a case study, this prototype system has been tested with Black Box and User Acceptance Test (UAT) in Indonesia Islamic Higher Education Institution. The finding reveals that the prototype system can be used as a performance measurement tool in measuring the readiness of Lean's service in Islamic Higher Education Institution.
