Abstract

The research entitled Effect of Total Quality Control and Just In Time on improving product quality and cost efficiency aims to analyze the effect of Total Quality Control (TQC) and Just In Time (JIT) on improving product quality and cost efficiency. This research was conducted at one of the manufacturing companies in Surabaya, namely UD. Sukri Dana Abadi. This study used descriptive qualitative method. The type of data used in this study is the type of primary data where researchers obtain data through direct data collection efforts. Methods of data collection is done by conducting interviews and observations on the object under study. The results of this study indicate that Total Quality Control (TQC) has an effect on improving product quality and cost efficiency, where the quality of the resulting product is in accordance with the specifications and Standard Operational Prosedur (SOP). While Just In Time (JIT) shows a significant effect on improving product quality and cost efficiency. The storage fee before Just In Time is Rp. 7,463,577 while the storage cost after Just In Time is Rp. 3,732,788 then there is a difference of Rp. 3,731,788 which means Just In Time can reduce costs by Rp. 3,731,788.

Abstract

This research is a qualitative study that explores the use of a timetable board as a learning tool to enhance student engagement in Mathematics, specifically the topic of time units, for Grade II A students at Baiturrohman GMI Jember Elementary School. The objectives of this study are to determine 1) The process of using the timetable board in teaching Mathematics, focusing on time units, for Grade II A students at this school, and 2) The improvement of student engagement in Mathematics, particularly in the topic of time units, through the use of the timetable board in Grade II A at this school. The data collection techniques include lectures (material delivery), observation, discussion, tests, and documentation. The subjects of this study are 18 students in Grade II A. The implementation of the learning activities using the timetable board as a teaching aid is deemed successful due to the students' significant curiosity during the learning process. This curiosity has led to increased student activity during the learning process, with a majority of students showing a 50% improvement in understanding the material related to time units in Mathematics. In conclusion, this research suggests that using the timetable board as a learning tool effectively enhances student engagement in Mathematics, particularly in the topic of time units, for Grade II a students at this Elementary School.
