The paper presents the algorithm in robust constrained model predictive control for uncertain piecewise affine with time-invariant state-delay system using saturated linear feedback controller. Polytopic uncertain piecewise affine with time-invariant state-delay system is considered, and polytopic description for saturated function is used in the f...

The paper presents the improved algorithm in robust constrained model predictive control for piece-wise affine systems using saturated linear feedback controller. Polytopic uncertain piece-wise affine systems is considered, and polytopic description for saturated function is used in the formulation. An infinite horizon worst-case performance functi...

The paper presents a feedback control of Linear Quadratic Regulator (LQR) scheme for Selective Catalytic Reduction (SCR) process in combined-cycle (CC) power plants. The SCR process is to reduce NOx emission at the CC power plants, prior to venting into the atmosphere by decomposing process using Ammonia (NH3) at the SCR catalysts. This process can...

The paper describes a development framework of e-Kanban (electronic Kanban) system for Indonesia automotive mixed-model production line. It is intended to solve problems found during the implementation of traditional kanban system in the subjected company. The traditional kanban system posed inefficiencies in the production line and it has been ide...

This paper presents the design and implementation of a poka-yoke system in a stationary spot welding (SSW) production line. The human-based SSW production process in a local automotive component company was considered in this study. Due to the repetitive and fast cycle-time of the production process, human errors are inevitable. Such errors lead to...

Control systems and computer science are two distinct and important fields of engineering. The development of cloud computing in computer science has become an enabler for the widely used controller in control systems to migrate to the cloud and has created a new field of research in cloud-based control systems (CCS). The paper used the systematic...

The Neural Networks (NN) model which is incorporated in the control system design has been studied, and the results show better performance than the mathematical model approach. However, some studies consider that only offline NN model learning and does not use the online NN model learning directly on the control system. As a result, the controller...

Network control system (NCS) approaches for distributed closed-loop control systems have been established in industrial control. However, recent advancements in cloud computing provide scalable, elastic, and low-cost networked computing capabilities over the internet, which can be utilized as an extension of NCS, in this term, cloud-based control s...

Human errors are inevitable due to the mass customization and complex supply chain, which must be considered in the Material Resource Planning (MRP) explosion calculation and the Supply Chain Procurement (SCP) distribution of sales orders. Such errors lead to SCP problems with the subject company. The research presents the design and implementation...

Grocery store BSR is an SME engaged in the sale of goods for basic daily needs. Today's business processes are still done manually. It has in-store sales services and a mobile sales team to reach a wider rural area in Central Java province of Indonesia. The competition in the grocery store SME business is tighter and increasingly competitive, so sh...

During the Covid-19 pandemic, teaching and learning activities were threatened with a decline in the quality of world education, including the quality of education in Indonesia. Students and teachers cannot interact to carry out educational activities at school. Meanwhile, in the world of education, interaction and communication are very important...

Konfigurasi dasar pada Router dan Switch Cisco merupakan hal yang harus dilakukan sebelum melakukan konfigurasi lanjutan dalam memanajemen jaringan komputer. Untuk mengkonfigurasi perangkat-perangkat tersebut dilakukan pada Cisco IOS (internetworking Operating Sistem) yaitu sistem operasi jaringan pada perangkat Cisco yang dapat diakses melalui Com...

Pendidikan sebagai industri produk dan jasa berbasis ilmu pengetahuan dan keterampilan menghadapi persaingan yang semakin kompetitif dengan banyaknya institusi baik dalam dan luar negeri yang operasional di Indonesia. Untuk meningkatkan daya saing, maka utilisasi teknologi informasi khususnya di era revolusi industri 4.0 menjadi kunci penting. Pene...

Perusahaan manufaktur terutama komponen otomotif menghadapi tantangan yang sangat beragam, terutama perubahan permintaan pelanggan yang semakin spesifik terutama dalam hal penggunaan teknologi Industri 4.0 di dalam proses produksi. Tidak banyak penelitian yang membahas pendekatan metode holistik implementasi teknologi Industri 4.0 untuk peningkatan...

The development of digitalization has a positive impact to opportunity expand an innovation as a form of continuous improvement. One of the manufacturing companies, PT TCH, wants to implement Industry 4.0 innovation with the thought of integrating data and analytics supply chains. One of its applications is labeling error with a proportion value of...

The paper presents the design of multivariable PI-controllers for an industrial boiler system. The design objective is to determine a controller that yields satisfactory performances for all three different operating conditions, where the classical criteria on step responses are used. The design is carried out by using a multi-objective design appr...
