Process improvement analysis in toll corridor development with lean six sigma approach: case in PT Jasamarga Related Business

Toll Corridor Development (TCD) is one of the businesses conducted by PT Jasamarga Related Business as a follow-up to the issuance of Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat (PUPR) No. 28 of 2021. In the development of its first TCD project, Jasamarga Related Business (JMRB) encountered issues that resulted in the delay of the project's completion. The purpose of this research is to analyze and make improvements to the causes of delays in the Taman Mini TCD project. In this research, the lean six sigma approach is used to analyze process improvements that can be carried out so that these problems can be minimized in the further development of TCD. To identify activities that cause delays in the implementation of this project, the critical path method (CPM) was used based on the results of interviews with those directly involved in the development of TCD project. From the activities that cause the delay, a causal analysis is carried out using a fishbone diagram, and then an analysis of possible improvements is carried out using a lean concept approach. Based on the analysis results, three main issues are identified, namely inadequate planning process, ineffective partner or consultant selection process and delays in construction completion. From the cause-and-effect analysis, it can be concluded that potential improvements can be made by implementing the concept of pull planning, improving the business process by reducing waste and enhancing value-added activities, establishing effective stakeholder management, and maximizing the use of technology-based applications to aid project control.

Implementation of Tight Glucose Control for Critically Ill Surgical Patients: A Process Improvement Analysis

Tight glucose control has been advocated as a method to improve outcomes of surgical critical care. However, continuous infusion of insulin has potential morbidity (e.g., neurologic consequences of hypoglycemia), and it remains unclear to what degree the glucose concentration must be controlled. We examined our performance in instituting a protocol for tight glucose control in our surgical intensive care unit (ICU). Prospective study of 220 consecutive patients (February, 2003-March, 2006) who received an infusion of insulin for glucose control for >24 h by protocol. Data collected included age, acuity (Acute Physiology and Chronic Health Evaluation [APACHE] III) score, sex, history of diabetes mellitus, organ dysfunction (Marshall), and death or survival. Infusion-related data included initial glucose concentration, time to glucose <120 mg/dL, h/day of glucose <110 mg/dL and <140 mg/dL, duration of infusion (days), insulin units/day, year of therapy, and complications. Analysis was performed by chi(2), analysis of variance, and logistic regression, with p < 0.05 considered significant. Insulin drips were required by 10.2% of patients (287/2,804); 29 of these (10.1%) had diabetes mellitus. The mean APACHE III score for the treated patients was 77 +/- 2 (standard deviation), and the mortality rate was 24%. Hypoglycemia (<60 mg/dL) occurred in 4.2% of patients. The trigger insulin concentration decreased over time (2003 vs. 2005) from 249 +/- 14 to 160 +/- 5 mg/dL, and the h/day of glucose <140 increased from 11 +/- 1 to 16 +/- 1. However, age, acuity, APACHE III, days of insulin, time to achieve glucose <120, h/day of glucose <110, and mortality rate were unchanged. By logistic regression, only the year of treatment (odds ratio [OR] 1.871; 95% confidence interval [CI] 1.177, 2.972; p = 0.008] predicted success in controlling the blood glucose concentration to <140 mg/dL; age, illness severity, diabetes history, and trigger glucose concentration [OR 0.996; 95% CI 0.992, 1.001; p = 0.11] did not. Success in implementing tight glucose control was modest, albeit improving, despite a specific protocol for administration. No medical reason could be identified for inability to achieve tight glucose control; therefore, successful implementation must be volitional. Education, particularly regarding hypoglycemia, and possible refinement of our protocol may improve our ability to control blood glucose in our ICU.
