The study starts by modeling a simple 2-DOF (degrees of freedom) moving platform that employs two actuators to provide two kinds of rotational motion on the moving platform and each motion is driven by an electrical motor. A preliminary study to better understand motion generation is conducted by deriving a mathematical model of the platform. Based on this model, the relationship between the rotations of the two driving motors and the pitch and roll movements of the platform is determined. The range of movements must be limited both in the pitch and roll planes to a certain maximum and minimum values of tilting angles. This preliminary design of the platform is introduced to demonstrate motions that might be experienced by the user in roll and pitch directions. The motion generated has fulfilled the constraint with respect to the vestibular system. Results of experimental works show that the first motor angle between -26° and 27° is suitable for the roll plane; meanwhile, the angles range of -52° and 54° for the second motor is suitable for the pitch plane. Furthermore, some simple experiments were conducted to examine the correctness of the model through the comparison between testing results obtained from simulation and experimental work. In the reported results, the moving platform was set to some initial poses and was driven to the home position and the recording showed acceptable results. This moving platform can later be used for more comprehensive experiments, i.e., vehicle dynamic testing, driving training purposes, and human factor analyses.

The implementation of a small-scale Micro-Hydro Power Plant which considering a 2-meter water head river will be discussed in this research. Therefore, a Micro-Hydro Power Plant with a Propeller turbine type was implemented. The turbine components include the turbine wheel, blades, guide vanes, turbine housing, turbine cover, and discharge pipe. Each component was manufactured using a 3D printing process with PLA filament. The testing process involved a miniature dam made from a container with a height of 1 meter, connected vertically with pipes. Water flowing into the turbine rotates the turbine wheel, causing it to rotate on the turbine shaft. Output data, including rthe number of rotations (RPM) and torque (M), were collected using sensors placed on the turbine wheel shaft. The testing results of the prototype Propeller turbine showed an efficiency of over 90% at a flow rate of approximately 0.008 m^3/s. Under the ideal design conditions with 90% efficiency, the prototype turbine would operate at a rotation speed of 2880 RPM and generate a power output (P) of 66 Watts.

This study proposes improving the performance of a fixed-axis multistage Savonius wind turbine by integrating a sixbladed guide vane. Guide vanes aim to direct the incoming wind towards the blades of the Savonius wind turbine so that it can increase the performance value of the turbine itself. There are two methods, the first method is computational fluid dynamics (CFD) simulation to evaluate the best performance guide vane angle variations. The second method is implementing real conditions using 3 m/s until 4.2 m/s wind speed. The implementation of the guide vane to the wind turbine will consider four (4) variants of angles (0°, 20°, 40°, and 60°). The purpose of testing with four kinds of guide vane angles is to find out which guide vane angle can provide the best results among other guide vane angles. This research proposed the initial design of the guide vane addition to the multistage Savonius wind turbine with a fixed rotary axis. From the CFD simulation, the implementation of a guide vane can improve the performance of the multistage Savonius wind turbine with a fixed rotary axis. On the other hand, for the proposed initial design in this research, the 20° angle of guide vane gives the best result compared to the 0°, 40°, 60°, and without guide vane.

An electric wheelchair is a mobility aid designed to support the activities of individuals with physical disabilities, particularly those who have difficulty moving independently. This device consists of several main components, including a mechanical frame with four wheels two drive wheels powered by electric motors and two caster wheels at the front as well as a control system in the form of a joystick, a battery as the power source, and a seat designed for user comfort. With the advancement of technology, it is essential to integrate more efficient and accurate control systems into electric wheelchairs. This study aims to design and develop a throttle and tachometer system based on a Hall-effect sensor for electric wheelchairs to enhance movement control and accuracy. The system allows users to operate the wheelchair to move forward, turn right, and turn left using only the joystick. The methodology includes modifying a conventional wheelchair frame, integrating a BLDC motor, designing the throttle system, and implementing a Hall-effect sensor for real-time wheel rotation speed measurement. The results show that the Hall-effect sensor-based tachometer system demonstrates a high level of accuracy, with a measurement error of only 0.32% compared to standard measuring instruments. The BLDC motor used in the system is capable of reaching a maximum rotational speed of 450 RPM. These findings prove that the developed system improves the performance and reliability of electric wheelchairs while providing better comfort and independence for users.

The problem of limited access to electricity in the agricultural sector will have a direct impact on the suboptimal operation of smart greenhouses, including irrigation systems, additional lighting, and sensor-based environmental monitoring. The absence of a reliable energy source makes it difficult for farmers to maintain the stability of the planting environment, especially in remote areas that are not covered by the PLN electricity network. This community service activity aims to design an off-grid Solar Power Plant (PLTS) system as an independent energy solution that is efficient, environmentally friendly, and accessible to farmers in the location. The methods used include direct surveys to obtain data on electricity load requirements, measuring location conditions to determine orientation and potential for solar radiation, and technical calculations of the system based on field data. The result of this activity is a PLTS system design with a 2320 Wp solar panel configuration, 3 kW inverter, and 48V 150Ah battery, which is projected to be able to meet the daily energy needs of 2880 Wh and can maintain greenhouse operations for two days without sunlight. This activity also provides benefits in increasing farmer literacy regarding solar energy technology and encouraging initiatives to implement similar off-grid PLTS systems independently. This community service activity shows that the design of an off-grid PLTS system based on actual needs has great potential to be replicated as a sustainable energy solution in the agricultural sector.

This study examines the capability of LIDAR (Light Detection and Ranging) to enhance autonomous vehicle navigation through laser-based distance measurement. LIDAR technology, which has become increasingly vital in robotics and autonomous vehicles, enables real-time object identification and mapping with high accuracy. The integration of LIDAR with the Robot Operating System (ROS) further enhances the system's capabilities by providing a robust framework for sensor data processing and control algorithms in autonomous system. In this research, LIDAR is applied to indoor navigation, focusing on mapping objects in the shapes of rectangles, triangles, and circles. The data obtained from LIDAR is used by a condition-based (if-else) navigation system on a mobile robot to determine the dimensions of objects and the location of their center points. The results show that LIDAR can provide effective feedback in navigation systems, with object mapping consistent with pre-configured maps. The mapping error rate recorded is 1.93%, demonstrating that this technology is reliable for autonomous navigation applications.

This research focuses on improving hydropower production by designing a turbine for the MaliringanRiver in Kalimantan Selatan. The rotational speed and torque will be the focus of maximizing power generation. This research used Computational Fluid Dynamics (CFD) to understand how the fluid flows and how efficiently the turbine works. The simulations helped us see how the fluid flowed, the pressure differences, and the speed of the water inside the turbine. The software COMSOL Multiphysics imitates how the fluid behaves and interacts in real-life situations. The utilization of SOLIDWORKS played a crucial role in the turbine's design process, facilitating an accurate representation of the turbine's geometry and the subsequent fabrication of a prototype propeller turbine, featuring an outer diameter measuring 0.27 meters and an inner diameter measuring 0.113 meters. The methodology resulted in a power efficiency of 76.45%, showcasing the possibility of significant enhancements in the efficiency of hydropower generation. The broader ramifications of this study emphasize the feasibility of tailor-made turbines for local hydropower initiatives, thereby supporting Indonesia's renewable energy plan by providing sustainable and efficient energy alternatives. This study emphasizes the collaborative utilization of Computer-Aided Design (CAD) and CFD technologies in the progression of turbine technology, thereby establishing a basis for future investigations in hydropower optimization.
