Design and Development of an IoT-Based Room Access Security System with Password Authentication and Real-Time Notification
IJCA
Room access security is an essential aspect of safeguarding both physical assets and sensitive data. Although the use of physical keys and access cards is still common, both methods have their weaknesses. Keys can be lost or duplicated, while access cards are at risk of being misused by unauthorized individuals. Such situations may reduce the level of security, especially if not supported by a reliable monitoring system. Therefore, a more modern and secure technology-based solution is needed to ensure room security through the implementation of an IoT-based access control system. This research designs a room access security system utilizing Internet of Things (IoT) technology, with authentication carried out through password input on a keypad device. If any suspicious access activity occurs, the system will automatically send a notification to the room owner’s smartphone. With this feature, the owner can directly receive information about both authorized and unauthorized access activities. The method applied in this research is prototyping, with a workflow that includes problem identification, data collection, system design, prototype development, implementation, and system evaluation. The results show that the IoT-based room access security system with password authentication via keypad functions properly. When the detected password input is correct, the door will unlock, and the electrical system in the room will be activated. If the password input is incorrect, the alarm will sound, and the system will send a notification to the owner’s smartphone. Consequently, the room owner can disable the password input function via the keypad and also monitor the room condition through CCTV access.

Vannamei shrimp (Litopenaeus vannamei) aquaculture is one of the most economically valuable sectors in Indonesia’s fisheries industry. However, manual feeding practices often lack consistency and accuracy, resulting in inefficient feed utilization and suboptimal shrimp growth. This study aims to design and evaluate a time-based automatic feeding system to improve feed management efficiency and reliability in vannamei shrimp farming. The research employs a prototyping approach, consisting of literature review, hardware and software design, system model development, and functional testing. The system integrates a microcontroller as the control unit, a Real-Time Clock (RTC) module for precise feeding schedules, and motor actuators for automated feed distribution. Additionally, a feed-level detection sensor is incorporated to monitor feed availability in the silo and trigger an alarm when the feed is nearly depleted. Experimental results demonstrate that the developed system is capable of executing feed distribution automatically based on predefined schedules while simultaneously detecting feed availability. The system’s integrated mechanisms improve accuracy, reduce dependency on human labor, and provide timely alerts for feed replenishment. Contribution this study lies in the integration of real-time scheduling with feed-level monitoring in a single autonomous system, which enhances precision, minimizes operational errors, and supports the implementation of smart aquaculture technology. This contributes to the advancement of sustainable vannamei shrimp farming practices, particularly in regions where feed management remains a critical challenge.
Kunjungi TautanDesign the prototype of integrated asphalt mixing plant (AMP)
Q4
The need for transportation infrastructure to support economic growth in a region is very important. Transportation infrastructure, in this case, roads, must be free of obstacles, in the sense that there are no holes or cracked roads that can cause discomfort in driving, which may also have an impact on the accumulation of vehicles on damaged roads. What often happens is a delay in the process of repairing damaged roads, because the local government does not yet have adequate equipment/devices to handle damaged roads. For this reason, this study aims to create a portable asphalt mixing plant (AMP) tool that is integrated with cutting tools, betel machines, compressors, and stampers. The purpose and objective of making an integrated portable AMP is to facilitate the process of handling road damage. The working principle of this integrated portable AMP is: when the road repair process is to be carried out, the integrated portable AMP tool will be taken to the location of the road to be repaired, where the initial stage is to cut the section of the road to be repaired. After the cutting process is complete, the next step is the process of fixing the section of the road that has been marked through the cutting process. The results of the repair will be lifted and cleaned using a compressor to get maximum results, then the surface is watered with tar, and the asphalting process to cover the damaged road sections can be carried out immediately. The asphalting process is carried out using a portable AMP tool, where the process of producing asphalt is as follows: first, each material (split stone, sand, cement) to be used is weighed to get the right composition, and the split stone and sand materials will be removed to the mixer section for the mixing process. Second, to get maximum results, the split stone and sand materials are heated to a temperature of 1500C. The heating process is carried out by adjusting the flame from the LPG gas cylinder, and the temperature is adjusted using a temperature sensor to get a temperature value of 1500C. After the temperature value is reached, the cement will then automatically enter the mixing section, accompanied by a gradual spraying process of hot asphalt into the mixing section. The mixing process will take place until the mixing time limit is complete. The method used in this study is the design method (prototyping), where the stages begin with data collection, tool design, tool manufacturing, tool testing, and implementation of the resulting tool.

The growth of the renewable energy industry, particularly solar panels, has become a major focus in efforts to reduce dependence on conventional energy sources. However, improving the efficiency and productivity of solar panels requires optimal maintenance of panel surfaces and proper temperature regulation. Accumulation of dirt and dust on the panel surfaces, as well as uncontrolled temperatures, can reduce electricity generation efficiency. Therefore, the development of a system that can automatically clean panel surfaces and regulate panel temperature becomes crucial in optimizing solar energy-based electricity generation. This research aims to design and build an automatic system that can periodically clean the surface of solar panels and regulate panel temperatures to enhance the efficiency and productivity of electricity generation based on IoT. The system is expected to optimize the performance of solar panels by reducing the negative impact of dirt accumulation and temperature fluctuations. An experimental approach will be used in this research to design and build a surface cleaning system and temperature regulator for solar panels. The system development will utilize sensors to detect the level of dirt on the panel surfaces and to monitor panel temperature. In addition, microcontrollers and actuators will be used to automatically control the system's operations, ensuring the solar panel surfaces are cleaned and the temperature is adjusted according to the panel's conditions. With the implementation of the proposed system, it is expected to significantly improve the efficiency of solar panel electricity generation by reducing the negative impact of dirt accumulation and temperature fluctuations. Additionally, this system is anticipated to reduce the need for manual maintenance costs and extend the operational lifespan of solar panels. Thus, this research will provide a valuable contribution to the development of more efficient and sustainable renewable energy technology.

Kunjungi TautanSecurity System Uses CCTV Camera as Facial Image Recognition using Face-API
IJCA
Security is a problem that cannot be separated from human life. Whether at home, on the go or at work. Currently, many implementations have been tried for security, especially in accessing a place or room. Several ways to ensure security, especially for people who are not supposed to be in certain places, are to limit the access rights of a person or group of people by giving keys, cards or pins to certain people using various technologies. CCTV cameras or Close Circuit Television can be used to monitor security. However, CCTV for monitoring security is still considered ineffective if there is an intrusion in a room, house, office or certain place because there must be an operator watching. This study aims to produce a system that will be used to recognize someone from their face so that it can be known and verified whether the person is registered and has access rights or is in a certain room and location without having to always be supervised by an operator. The method used is the javaScript module, namely face-api.js in the form of an open source machine learning framework with varying facial recognition test results, especially at distances above 300 cm. The decrease occurs varies, at a distance of 350 cm one face has 60% accuracy, at a distance of 400 cm the accuracy is only 50%. On 2 faces at the same time the accuracy level on the first face is 350 cm the accuracy level is 70% and the second face is 60%, at a distance of 400 cm the accuracy level on the first face is 50% and the second face is 90%.
