    Optimized PID Control for Enhanced Electric Power Steering System Performance

    Authors: Rodi Hartono ; Hyun Rok Cha ; Kyoo Jae Shin

    DOI: 10.1109/INCITEST64888.2024.11121507

    Abstract:

    This research investigates the application of a proportional-integral-derivative (PID) controller for controlling an electric power steering (EPS) system equipped with a brushless direct current (BLDC) motor. EPS is an advanced automotive technology to assists drivers by reducing the physical effort needed to steer a vehicle and enabling precise computer-controlled steering in autonomous vehicles. EPS systems offer significant benefits over traditional hydraulic systems, including improved energy efficiency and steering precision. While EPS systems can present challenges due to their nonlinear characteristics, this study focuses on their linear range where the PID controller’s simplicity and effectiveness are beneficial. By optimizing PID parameters, the controller achieved precise tracking, fast transient response, and minimal steady-state error. Performance evaluation using a ± 10° angle target showed a rise time of 0.155 seconds, a settling time of 0.307 seconds, and an overshoot of 3.6% for a +10° target, and a rise time of 0.155 seconds, a settling time of 0.310 seconds, and an overshoot of 3.3% for a -10 target. These results show the PID controller’s capability to deliver consistent and accurate control in the EPS system, particularly when operating within its linear range. © 2024 IEEE.

    DOI: –

    Abstract:

    Electric energy is a vital element for the Indonesian community. However, in frontier, underdeveloped, and remote areas, access to electricity is uneven. An appropriate solution is necessary to overcome these supply limitations. This research aims to construct a micro hydro power plant utilizing existing river flows. The research employed descriptive analysis with a qualitative approach, while the equipment’s performance analysis used the fuzzy time series method. Findings indicate that micro hydro technology can generate up to 40 kW using four generators, relying on a minimum river flow rate of 60 litters per second. This system can meet the needs of 72 households with a lifespan of up to 15 years. The core concept was to use river flow to drive turbines, generating electrical power. Consequently, the government can minimize electricity development costs from major urban centres. Ultimately, micro hydro power generation technology serves as a solution for frontier, remote, and underdeveloped areas, providing access to electricity and illumination, and supporting the community’s living requirements. © 2024 Taylor’s University.

  • A Modular Intelligent System for Energy Saving Using Fuzzy Logic and Artificial Neural Network Based on the Concept of Internet of Things

    A Modular Intelligent System for Energy Saving Using Fuzzy Logic and Artificial Neural Network Based on the Concept of Internet of Things

    Authors: Fadhila Azzahra ; Rahma Wahdiniwaty

    DOI: 10.1063/5.0255654

    Abstract:

    The purpose of this research is to build an intelligent system of control and monitoring of electrical energy at home and to find out the amount of efficiency that can be achieved after implementing a control and monitoring system of daily electrical energy at home. The use of electrical at home is a waste of energy which of course is often not realized by the users. Even though, this is caused by the many uses of electronic devices at home that must be used and live continuously, for example: the use of lights, water heater, Air Conditioners (AC) and others. Although these devices can be set up and work automatically, automatic devices only rely on time and condition variables. To save energy more efficient, homes need to be equipped with intelligent systems that can be control and turn on electronic devices only when needed. The method that will be applied in this research is by combining fuzzy logic and the integration of Artificial Neural Network (ANN). Besides that, this system will be built using the concept of IoT (Internet of Things). The result of this research is produced an IoT device for intelligent Controlling and Monitoring of Electrical Energy with fuzzy logic and ANN methods. This current research is developing an ESP32-based smart device for the internet of things that can be used to monitor and control electrical energy using fuzzy logic and Artificial Neural Network (ANN) methods. However, current research has found that this device can improve energy consumption at home by 28-37%. © 2025 Author(s).

    DOI: –

    Abstract:

    This study implements the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method to evaluate and mitigate occupational risks in the manufacturing construction sector. A bibliometric analysis reveals a growing yet insufficient number of studies applying structured risk control frameworks like HIRADC in industrial settings, particularly in developing countries. Using a descriptive approach, data were collected through field observations, interviews, and document analysis. Seven hazards were identified, resulting in five low-risk and two moderate-risk classifications using a probability–severity matrix. Control measures were implemented following ISO 45001:2018 standards, including engineering controls, administrative actions, and personal protective equipment (PPE). The results demonstrate that HIRADC enhances workplace safety awareness and reduces risk levels. This study contributes a practical safety framework for manufacturing environments while reinforcing the relevance of SDG-aligned and bibliometrically justified research in occupational health. © 2025 Bumi Publikasi Nusantara.

    Integrating Corporate Social Responsibility with Stakeholder Role in Small and Medium Enterprise (SME) Projects: The Case of PT Chevron Geothermal Indonesia

    Author: Desayu Eka Surya, Wan Amizah Wan Mahmud

    DOI: 10.17576/JKMJC-2025-4101-18

    Abstract

    This study explores the integration of Corporate Social Responsibility (CSR) and Stakeholder Theory in PT Chevron Geothermal Indonesia’s (PT CGI) small and medium enterprise (SME) projects in Desa Samarang and Desa Pasirwangi Garut, Java Island, Indonesia. CSR has become a strategic tool for businesses to promote economic empowerment, environmental sustainability, and social well-being. This study aims to examine how PT CGI’s Super Chicken, Banana Plantation, and Mushroom Cultivation initiatives align with stakeholder interests, ensuring sustainable development. Grounded in Stakeholder Theory, which posits that businesses should address the interests of multiple stakeholders, this research employs a qualitative case study approach, collecting data through semi-structured interviews, document analysis, and direct observations. Sixteen key informants, including PT CGI representatives, local government officials, and SME beneficiaries, participated in the study, conducted between January and July 2016. Findings reveal that stakeholder engagement is critical to CSR success. The Super Chicken project enhanced food security and local income, the Banana Plantation initiative improved agricultural sustainability, and the Mushroom Cultivation project provided economic opportunities, particularly for women and marginalized groups. These initiatives illustrate the purpose of CSR in community-driven development, the value creation achieved through economic growth and skill development, and the interdependence between businesses and communities. The study concludes that CSR is most effective when implemented through stakeholder-driven models, fostering long-term self-sufficiency and shared value creation. This research contributes to CSR and Stakeholder Theory literature by providing insights into how corporations can drive sustainable development through collaborative, purpose-led CSR strategies. © 2025, Penerbit Universiti Kebangsaan Malaysia.

  • Geographic Information System (GIS) Application to Identify the Distribution of Tourist Attractions and Supporting Facilities Related to the Sustainable Development Goals (SDGs)

    Geographic Information System (GIS) Application to Identify the Distribution of Tourist Attractions and Supporting Facilities Related to the Sustainable Development Goals (SDGs)

    Author: Warlina, Lia ; Afredi A.

    DOI:10.17509/ijost.v11i2.89803

    Abstract

    The purpose of this research is to examine the distribution patterns of tourism attractions, hotels, and restaurants, and to explore their implications for achieving the Sustainable Development Goals (SDGs) in Lembang District. To analyze these distributions, a quantitative approach was applied using nearest neighbor analysis and Geographic Information System (GIS) techniques. A total of 38 tourism attractions were identified, including 17 natural attractions, 17 artificial attractions, and four cultural attractions; all exhibiting dispersed distribution patterns. There are 32 hotels with random distribution patterns and 178 restaurants that are clustered. Natural attractions are characterized by hilly terrain, forests, valleys, and rivers, which result in physical separation between some sites. In contrast, artificial and cultural attractions tend to be concentrated in more accessible areas, particularly along main routes. Notably, villages such as Cikahuripan, Cikidang, Mekarwangi, Suntenjaya, Wangunharja, and Wangunsari contain tourism attractions but lack adequate supporting facilities, including hotels and restaurants. The spatial allocation of tourism attractions, accommodations, and restaurants significantly influences the achievement of the SDGs. Tourism contributes to 14 of the 17 SDGs, especially SDG 8 (promoting economic opportunities), SDG 1 (reducing poverty), and SDG 5 (advancing gender equality). © 2026 Tim Pengembang Jurnal UPI.
