Abstract

The public health monitoring system at the Integrated Service Post (Posyandu) is a form of integrated health service carried out in a Puskesmas working area where the implementation is carried out in each Kelurahan or RW. It can be said that the system is not optimal because during the Covid-19 virus pandemic we have to minimize activities that are physical in nature, such as the use of health books which are currently being used less than optimally for the community because it allows for the spread of the Covid-19 virus. Then the monitoring system still uses email for sending data from Posyandu to Puskesmas, Puskesmas to the Health Office and Health Office to the Ministry of Health. This system is not profitable, because in addition to requiring a lot of time for data transmission, the data sent may fail or not be successfully sent. Solutions related to these problems can be solved by creating a multi-platform-based maternal and child health monitoring system, the monitoring system here can already be done in real time using a database so there is no need for manual data transmission such as via email. In just a few seconds, the data received by the Posyandu from the community will be monitored directly by the Puskesmas, the Health Service and the Ministry of Health. In addition, the data that was previously collected in the form of a book is now replaced with an application that can be opened via a smartphone which contains data along with children's development charts. So that the community and other health care parties can access children's development simply by using a smartphone. In addition, the data will also be managed very well and the data will be maintained when using the application when compared to using a book, the data can be damaged or lost.

Abstract

Tahap yang paling penting dalam proses pembuatan sebuah chip adalah pengujian. Pengujian dilakukan untuk memastikan hasil rancangan sesuai dengan spesifikasi yang telah ditentukan. Proses pengujian juga dilakukan untuk mengidentifikasi fault yang muncul pada sebuah rangkaian. Algoritma yang dilakukan untuk menghasilkan test pattern pada rangkaian sequensial adalah scan chain. Rangkaian yang diuji adalah rangkaian s641 (ISCAS 89) dengan metode non scan, full scan, dan partial scan. Rangkaian s641 dioptimasi dan dimodifikasi terlebih dahulu dengan menggunakan Synopsys Design VisionTM. Seluruh D-Flip-Flop (DFF) pada rangkaian s641 diubah menjadi Scanable D-Flip-Flop (SDFF) dan kemudian ditambahkan scan-chain yaitu port scan-in, scan-out, dan scan-enable pada rangkaian. Hasil pengujian didapatkan nilai fault coverage untuk rangkaian s641 setelah dioptimasi bernilai diatas 95% dengan pengujian partial scan sequential ATPG menggunakan penggantian 3 SDFF. Apabila dilakukan penggantian sebanyak 15 SDFF, maka nilai fault coverage yang didapatkan mendekati 100% dengan pengujian yang sama.

Abstract

Increasing awareness of the importance of head personal protective equipment in industrial and construction environments has become a major concern in efforts to improve occupational safety. This research developed an early detection system for the use of computer vision-based head protective equipment using the YOLOv7 model and the Jetson Nano controller. The YOLOv7 algorithm was chosen for its ability for fast and accurate object detection. The YOLOv7 model was trained with a total dataset of 2799 images and iterations of 100 epochs to detect head personal protective equipment with a high degree of accuracy. The system captures imagery, activates a warning alarm, and sends a notification to Telegram when a violation occurs on an object that is not wearing a safety helmet. The test results using the confusion matrix method showed that the developed system was able to detect head personal protective equipment with an accuracy rate of 97.23%, which shows the system's ability to recognize personal protective equipment with very high accuracy. In addition, the system also showed a precision value of 98.71% indicating that all detections performed were correct, and a recall of 95.63% which describes the system's ability to recognize most of the head personal protective equipment available. The average FPS result using GPU with CUDA on Jetson Nano reached 5,723 FPS.

Abstract

Rural communities in Cibodas, East Bandung, face serious challenges in aquaponic farming practices, particularly in the uneven application of conventional fertilizers. This imbalance results in suboptimal crop quality, reducing the potential for agricultural productivity in the region. To overcome this obstacle, an innovative solution is needed in the form of an Internet of Things (IoT)-based automatic liquid fertilizer irrigation system. This system is designed to distribute fertilizer evenly to all plants, ensuring that each part of the plant receives adequate nutrients, and that fertilizer is applied efficiently. The use of this system not only increases the efficiency of farmers' work, but also contributes to improving the overall quality and quantity of crop yields. The stages of activities in the implementation of this community service are the development of an automatic liquid fertilizer irrigation system based on the Internet of Things (IoT), the application or implementation of the system, and finally the socialization of the use of the system. This community service activity is a series of student community service activities carried out in October 2024. The elements involved are the community of Cibodas Village, lecturers and students of Politeknik Manufaktur Bandung. As a result of this service activity, the community understands and can apply agricultural technology, in this case IoT-based automatic liquid fertilizer spraying technology with remote control. The liquid fertilizer spraying and watering system can increase the efficiency of time and energy. It is hoped that the technology that has been developed will be one of the effective solutions to the problem of uneven spraying of plant fertilizers.
