"In January 2005, to continuously improving and delivering the customer value, which helping customers and distributors to meet their needs and satisfaction, Company XYZ distributes the VOC (Voice of Customer) to Distributor ABC as a Local Distributor of Company XYZ in Indonesia for Specialty Chemicals Products. The feedback from Distributor ABC indicates that one key point, which considered as very important and prioritized to be improved by Company XYZ is the Order Lead Time.As the response, Company XYZ in Indonesia, lead by Distributor Coordinator of Company XYZ initiates and performs this Six-Sigma Project to reduce the Order Lead Time. Order Lead Time is defined as the amount of time required from the submitted Purchase Order (PO) by Distributor ABC to the time the Distributor ABC received the order. The term and condition of the Order from Distributor ABC to Company XYZ is Free On Board (FOB) Singapore. The scope of the project will be limited to the Consumable Products imported from Manufacturing/Blending Plant located at China, which contribute about 75% of total products ordered by Distributor ABC.The Distributor ABC expects to have fast and on time delivery, in order to have a better management of local inventory in Indonesia, and reducing the inventory level in the warehouse that in return will significantly reduced the inventory cost. To anticipate late delivery to the End Customer, Distributor ABC provides 3 months of inventory level at the warehouse in Indonesia.To find the best solution on how to reduce the Order Lead Time, the problem solving methodology of Six-Sigma DMAIC (Define-Measure-Analyze-Improve-Control) has been using as a tool to find the source of variation, solving the problem, and improving the existing process. The project is based on the baseline data from October 2004 to March 2005 and project implementation from April to September 2005.The Six-Sigma Project result shows that the major problem was occurred due to the availability of the raw material in Company XYZ Blending Plant at China and the availability of products in the Warehouse of Company XYZ at Singapore and China. Thus, as the consequences, the products should be produced "Just in Time" at the Blending Plant in China that obviously prolongs the Order Lead Time, especially when the raw material is not available.Based on the result of Six-Sigma Project, the best solution to reduce the Order Lead Time and to manage the inventory Control is by using a Forecast Order. Forecast Order will help Company XYZ to manage and provide buffer stock at Singapore and China Warehouse and also prepare the raw material in the Blending Plant at China. Since the products are available in the Company XYZ Warehouse, the Order Lead Time to Distributor ABC could be reduced.The implementation of Forecast Order and inventory management has been giving a significant impact on the Order Lead Time. The implementation of the Forecast Order in April till September 2005 shows that the Order Lead time can be reduced from the average of 45 days to 17 days. Distributor ABC is also able to reduce the inventory level at the warehouse in Indonesia from 3 months to 1 month. The inventory cost could be reduced by approximately 73%."

"Proses regulasi diri diduga merupakan mekanisme yang mendasari Penggunaan Smartphone Bermasalah/PSB terutama di kalangan usia emerging adults. Penelitian-penelitian sebelumnya telah menemukan bahwa komponen perilaku dari sistem regulasi diri, yaitu kontrol diri, dapat menjadi prediktor negatif yang signifikan untuk PSB. Namun, terdapat penelitian-penelitian lainnya yang tidak menemukan hubungan yang signifikan antara kontrol diri dan PSB. Penelitian ini menduga bahwa pemahaman mengenai proses regulasi diri dalam PSB perlu memperhitungkan interaksi komponen perilaku dan komponen kognitif dari sistem regulasi diri. Partisipan, yang terdiri dari emerging adults yang aktif menggunakan smartphone (N=130), mengisi pengukuran kontrol diri (Brief Self Control Scale), penggunaan smartphone bermasalah/PSB (Smartphone Addiction Scale-Short Version), serta mengerjakan tugas kognitif Stroop sebagai pengukuran kontrol inhibisi. Hasil analisis moderasi PROCESS Model 1 menunjukkan bahwa kontrol inhibisi memoderasi hubungan antara kontrol diri dan PSB secara signifikan. Hal ini menunjukkan bahwa peran kontrol diri dalam mengurangi kecenderungan perilaku PSB dapat diperkuat dengan peningkatan performa kontrol inhibisi. Diskusi terkait hasil penelitian ini akan menekankan interaksi kontrol diri dan kontrol inhibisi sebagai sistem regulasi diri dalam mendukung perilaku penggunaan smartphone yang lebih sehat.

The process of self-regulation has been proposed to be the underlying mechanism of Problematic Smartphone Use (PSU), particularly among emerging adults. Previous studies have demonstrated that self-control, a crucial behavioral component of the self-regulatory system, can significantly predict PSU. However, conflicting findings have been reported, with some studies failing to establish a significant relationship between self-control and PSU. This study proposes that a comprehensive understanding of the self-regulatory process in PSU should consider the interplay between the behavioral and the cognitive component of the self-regulatory system. A sample of 130 Indonesian emerging adults, who actively use smartphones, completed measures of self-control (Brief Self-Control Scale), problematic smartphone use (Smartphone Addiction Scale-Short Version), and performed the Stroop task as an inhibitory control measure. The results of the moderation analysis using PROCESS Model 1 revealed that inhibitory control significantly moderated the relationship between self-control and PSB. The result suggests that enhancing inhibitory control performance can strengthen the role of self-control in reducing individuals’ tendency towards PSU. The discussion of the current study's findings will underscore the interaction between self-control and inhibitory control as a self-regulatory system that supports healthier smartphone usage behaviors."
