Abstract

River has strategic role as one of the natural resources that supports peoples lives. Ciliwung has the most widespread impact during the rainy season because it flows through the center of the city of Jakarta and across many villages, dense housing and slums. This paper aims to formulate a concept for managing a slum neighborhood on the banks or Ciliwung watershed. This concept is supported by the main concept of the Green Water Front. Based on the results of our analysis, it is known that the low citizens living in the area Ciliwung River in maintaining the environment. To increase awareness of citizens in maintaining the environment, we carry a concept of Green Water Front, which is the core of this concept will change as the river behind the house into the river as the front of the house. So the river will be a point of interest. On this concept there will be a bridge crossing over the river which we call the bridge "Rhombus". The concept of Green Water Front will increase the interaction between people separated the river because of its function as well as bridges. The public rooms are located in the middle of the Green Water Front can serve as a plaza, childrens playground, or farming. So that this concept can be implemented properly, it must be required cooperation from various parties including students and university, government, and communities around the watersheds that are subject to the application of this concept.Keywords: Green water front, Ciliwung river, seedy neighborhood

Abstract

The Sumba Island electricity is divided into two central systems, the Waingapu and Waikabubak. The load growth of the Waikabubak system, which is in the Sumba Jaya area, is predicted to be higher than that of the Waingapu system. The existing power generation systems in this area consist of solar PV system (PLTS) Bilacenge along with vanadium redox battery (VRB), micro hydro power plant (PLTMH) Lokomboro and Umbuwango, the diesel power generation (PLTD) Waikabubak and Waitabula (Baru Laratama). The existing configuration of these systems produces renewable energy penetration below 45%. Hence, this condition shows that renewable energy exploration has yet to be carried out optimally, even though this area has an average potential for solar irradiation and wind speed reaching 5.84 kWh/day and 5.29 m/s, respectively. This research proposes an optimization design for developing the electricity system in the Sumba Jaya area, including Sumba Barat and Sumba Barat Daya Regency, East Nusa Tenggara Province. The proposed design searches for the optimal capacity of the existing system by adding renewable energy power generation in the form of wind turbine generation (PLTB) in Wanokaka with a capacity of 3,000 kW. The modelling was conducted using Hybrid Optimization of Multiple Energy Resources (HOMER) software to assess the feasibility of the proposed system. As a result, the payback period of the proposed system is achieved around four years, with the net present cost (NPC) and cost of energy (COE) lower than the existing system. In addition, the level of CO2 emissions was reduced, with the increased renewable energy penetration rate at around 96.6%.

Abstract

Recent advancements in sensorless Field-oriented Control (FOC) of Surface Permanent Magnet Synchronous Motors (SPMSMs) have improved system reliability and cost-effectiveness. However, limitations such as speed chattering and inaccurate rotor position estimation remain problematic for Electric Vehicle (EV) applications. This study developed a sliding mode observer-phase locked loop (SMO-PLL) algorithm applied to sensorless FOC in SPMSMs. The SMO predicts the back EMF of the SPMSM, which the PLL then uses for precise rotor position and speed estimation. Simulations conducted in MATLAB Simulink demonstrate that the SMO-PLL significantly reduces chattering and achieves a rotor position estimation error of only 1 rad/min. While the quantitative integral error criteria for SMO-PLL (IAE: 0.0868, ITAE: 0.3069, ISE: 0.0229, ITSE: 0.0834) are slightly higher than those of Field Observer (FO) and Extended Electromagnetic Field Observer (EEMFO), speed control analysis confirms that SMO-PLL delivers a rapid steady-state response with minimal overshoot and oscillation. These findings are crucial for applications where speed stability is essential for passenger comfort and safety, highlighting the SMO-PLL's potential as a robust sensorless control solution for future EVs.

Abstract

Seatbelt usage is essential for minimizing injury risk during vehicular accidents. The monitoring seatbelt system in modern vehicles can be easily tricked into not displaying the warning alert. Car seatbelt detection, utilising real-time object detection, is employed to monitor seatbelt usage. However, the accuracy of such systems needs to be further evaluated under low-light and bright-light conditions. This study aims to develop a car seatbelt monitoring system using a real-time object detection algorithm, which will be tested in low-light and bright-light scenarios. The system integrates a trained YOLOv5 model into embedded hardware, which interfaces directly with the vehicle’s ignition system, enabling or disabling engine start based on seatbelt usage. Notifications are also delivered through LEDs, a buzzer, and Telegram messages. This system has an accuracy of 95.75%, precision of 99.1%, recall of 96.2%, and an F1-score of 97.2%. The results show that the system can generate a better confidence score under bright-light conditions than under low-light conditions. This work offers tangible proof of the efficacy of applying intelligent object detection models for real-time driver monitoring, particularly in enhancing compliance through physical intervention and IoT-based alerts.

Abstract

The scalability of FreeRTOS makes it a popular choice for embedded systems, yet its behavior on processors with severe memory constraints remains poorly quantified. This study conducts a rigorous empirical evaluation of FreeRTOS on the Arduino Uno platform, based on the ATmega328P microcontroller with only 2KB of SRAM. We introduce a systematic benchmarking framework designed to probe the kernel's operational limits by measuring task capacity, stack depth requirements, and scheduler overhead under controlled stress conditions. Our findings reveal that heap fragmentation is the primary determinant of task capacity and precisely quantify the performance trade-offs associated with kernel configuration. The results provide a set of validated, practical guidelines for developers, enabling more reliable design choices for deploying RTOS-based solutions on resource-limited hardware commonly found in cost-sensitive IoT applications.
