Abstract

The number of traffic violations that occurred in the Depok area from 2017 to 2019 has fluctuated, from 2017 as many as 33,600 cases, 2018 as many as 52,100 cases and 2019 as many as 42971 cases. In each year an increase in violations occurs and the ability of applications to distribute data will decrease. This happened to the Traffic Unit of the Depok Metro Police, with the increasing number of handling data on accidents and data on violations that occurred in Depok City, of course, it must be balanced with an increase in the system as an online reporting medium. From the above explanation, it can be concluded that to solve this process, it is necessary to have a new architecture, namely the microservice. Microservice allows the development of software functions to be broken down into small, focused service parts, making the service have resource capabilities that can be precisely managed and dividing application functionality into small and interconnected services into a single business application process. This architecture integrates data between units, distributes data related to cases of traffic violations or accidents that occur in real time by local police officers, and provides information on traffic violations and specific accidents.

Abstract

Recently, Deep learning methods with Convolutional Neural Networks (CNNs) have been widely used for image classification tasks. CNN has an unrivaled advantage in extracting discriminatory image features. However, many existing CNN-based methods are designed to go deeper and more significant with more complex layers that make them challenging to implement on mobile devices or real-time devices that use microcontrollers like raspberry pi, Arduino, and immediately. This is overcome by using a Light Convolutional Neural Network (LCNN), so it needs to experiment to test the difference in LCNN performance on a personal computer and a raspberry pi four microcontrollers with a Raspbian operating system. Experiments will be carried out using several performance measures: accuracy, F-1 score, recall, precision, and time to get performance results from deep learning. As such, the results and model architecture will confirm performance differences across individual devices and show how the model performs on resource-constrained or real-time devices. Tests show that the performance of the raspberry pi, which is a tool with limited resources, does not affect the quality of image recognition but affects the recognition processing time because the raspberry pi requires a longer processing time to perform one data or photo recognition process. This will accumulate the time required for processing many data, so it can conclude that the raspberry pi and tools with limited resources are not very practical for conducting recognition training and carrying out a recognition process that contains a lot of data or photos in one process.

Abstract

Teachers and staff at Sekolah Alam Indonesia (SAI) Cibinong have been using a manual attendance system, which has caused delays in attendance recapitulation and inefficiencies in reporting and monitoring. To address this problem, the Participatory Action Research (PAR) method was adopted, emphasizing active involvement from the school community in every stage of the program. The PAR method was chosen because it fosters a collaborative approach, ensuring that the solution is tailored to the specific needs and context of the school. The Smart Record System, an automated Internet of Things system that uses facial detection technology for precise attendance recording and reporting, was introduced by the community service program to address this problem. To increase participants' understanding of data security, this program offered a seminar on Personal Data Protection in social media and system implementation. To guarantee efficient use of the technology, the methodology included system installation, integration with IoT components, and training sessions. After providing participants with practical system operation experience, system assessments and feedback gathering were conducted to gauge the implementation's efficacy. The outcomes demonstrated how the smart attendance system, which offered real-time attendance data and prompt reporting, greatly simplified the attendance management procedure. Based on the questionnaire responses, the system achieved an average user satisfaction score of 3.86 out of 5, reflecting a 77.2% positive agreement among users. Furthermore, the reliability of the questionnaire, measured by Cronbach’s Alpha, was 0.85, indicating a high level of consistency in the responses. These quantitative findings confirm that the system significantly improved the efficiency of attendance management while being well-received by teachers and staff.

Abstract

Electricity is one of the vital energy sources that is highly demanded by society. However, there is still an imbalance in the availability of electricity in Indonesia, especially in remote or isolated areas that are difficult to reach by the national power grid (PLN). To address this issue, one of the solutions that can be employed is Micro Hydro Power Plant (PLTMH), which is a renewable power generation system. In PLTMH, water turbines are utilized as a medium to generate rotation through the force exerted by the flowing water from a certain height. The water head plays a significant role in the performance of the water turbine, where a higher waterfall and impact on the turbine blades result in faster rotation and greater energy production. This study presents the experimental results of an Undershot Water Turbine made of Acrylic material with 8 blades and a blade angle of 15°. The experiment employed a water volume of 58 liters and a water gate opening of 3 cm. The results showed that the water turbine generated a power of 0.41584 watts, while the power produced by the flowing water was 1.23186 watts. The efficiency of the water turbine in this experiment reached 33%. Based on this research, it can be concluded that the proper utilization of an Undershot Water Turbine made of Acrylic material with an appropriate number and angle of blades can yield significant power output. Moreover, the achieved efficiency level of 33% demonstrates that the water turbine can serve as an efficient alternative for renewable electricity generation.
