Abstract

Cardiovascular disease is the main cause of death globally causing challenges in the world of health, including in Indonesia. Lack of public knowledge about cardiovascular disease is very dangerous if preventive measures are not taken immediately. Currently, the treatment of cardiovascular disease is done manually, takes a long time, costs a lot and the practice hours of cardiologists are short. To overcome this problem, researchers implemented an expert system that can diagnose cardiovascular disease and a web system is needed to identify symptoms and apply the certainty factor method as a decision-making tool in overcoming public uncertainty in early examinations. This system involves 6 disease data, 29 symptom data, and 20 case data. In this study, testing was carried out based on the results of expert validation with accuracy system test data, resulting in an appropriate level of symptom and disease compliance and an accuracy level of 100% obtained from 20 data checks.

Abstract

Earthquakes are one of the natural disasters that frequently occur in several regions of Indonesia. The government can map in advance the areas that are prone to earthquakes. The results of this mapping can serve as a reference for prioritizing aid distribution to regions with high earthquake disaster potential. This study utilizes the Weighted Sum Model (WSM) to map the priority areas for government aid distribution. The WSM method provides an output ranking regions from high priority to low priority. Several criteria are considered, including the number of exposed populations, the number of disabled individuals, the number of impoverished residents, the number of vulnerable age groups, and the class of exposed populations. Since the exposed population class is non-numeric data, this study employs the Likert method to convert it into numeric data. In addition to criteria, this study also utilizes alternative data, specifically the names of sub-districts in Pacitan Regency, East Java. The combination of the Likert and WSM methods helps in recommending regions with earthquake disaster potential as priority aid recipients. The most prioritized region for receiving aid is Tulakan Sub-district, Pacitan Regency, East Java. Based on WSM calculations, Tulakan Sub-district has the highest WSM final score of 26,642.35, making it the top-priority region compared to others.

Abstract

Crimes involving individuals on the Wanted Persons List (DPO) are a serious issue in the modern era. Airports, as hubs of human mobility, play a crucial role in preventing criminal suspects from escaping. However, the high volume of activity at airports necessitates a security system that not only relies on human personnel but also leverages advanced technology. To address this issue, the development of an IoT-based DPO Automatic Barrier System is proposed. This system utilizes components such as ESP8266, a servo motor, a buzzer, and jumper wires, integrated with a Laravel-based website and SQL database. The system operates in real time by detecting National Identification Number (NIK) data linked to the DPO database. The ESP8266 module serves as the primary communication interface, while the servo motor controls the automatic barrier. When an individual listed in the DPO database is detected, the system triggers a buzzer as a warning alarm and activates the barrier to restrict access. The implementation of this system is expected to enhance security and improve monitoring effectiveness at airports for individuals registered in the DPO database.

Abstract

The rapid advancement of information and communication technology has significantly influenced business activities, particularly in rural areas. However, Desa Tanah Abang Utara remains categorized as a blank spot, where mobile communication services such as Global System for Mobile Communications (GSM) and other providers are not optimally available. This condition hampers internet access, limiting local businesses in utilizing digital platforms for marketing and sales. This study aims to implement a fiber optic (FO) network in Desa Tanah Abang Utara as a solution to improve internet connectivity. The research employs the Action Research method, which consists of five stages: diagnosing, action planning, action taking, evaluating, and learning. The installation process involves configuring routers, VLAN settings on switches, FO cable installation, and Optical Line Terminal (OLT) deployment. Network performance is evaluated using Wireshark software to measure key parameters such as throughput, latency, and packet loss. The results show that the implemented FO network significantly enhances internet access reliability, providing a stable and high-speed connection for the community. This improvement enables local businesses to leverage digital platforms for business expansion and enhances overall socio-economic development. The study highlights the importance of fiber optic networks in overcoming digital disparities in rural areas and serves as a reference for policymakers in developing telecommunications infrastructure in underserved regions.
