Abstract

Laboratorium komputer Fakultas Ilmu Komputer Universitas Bhayangkara Jakarta Raya (Fasilkom Ubhara) sebelumnya bergantung pada jaringan hotspot dari provider ISP yang tidak dapat dikonfigurasi secara mandiri, sehingga tidak tersedia mekanisme pembatasan bandwidth, manajemen pengguna, maupun autentikasi akses yang memadai. Kondisi ini menyebabkan penggunaan bandwidth yang tidak terkontrol dan ketidakmampuan administrator dalam memonitor aktivitas jaringan. Penelitian ini bertujuan untuk mengimplementasikan infrastruktur jaringan WLAN mandiri berbasis MikroTik RouterOS yang dilengkapi dengan manajemen hotspot menggunakan captive portal dan pembatasan bandwidth melalui Simple Queue. Metode yang digunakan adalah Network Development Life Cycle (NDLC) yang mencakup tahapan analisis, desain, simulasi, implementasi, monitoring, dan manajemen. Hasil implementasi menunjukkan bahwa jaringan WLAN berhasil dibangun dengan konektivitas penuh ke internet (packet loss 0%, avg-rtt 1ms), pembatasan bandwidth efektif pada 5 Mbps upload/download per segmen jaringan dengan hasil speedtest mencapai 4,31 Mbps download dan 4,72 Mbps upload, serta sistem hotspot captive portal yang berfungsi dengan autentikasi berbasis username dan password melalui domain labsiber.com. Penelitian ini menyimpulkan bahwa implementasi MikroTik secara signifikan meningkatkan kontrol administrator terhadap jaringan laboratorium dibandingkan kondisi sebelumnya.

Abstract

Laptop damage diagnosis at PT Tsurtech Solution is currently carried out manually, which can take more time and requires the technician's experience to identify problems accurately. This research aims to design and implement a web-based expert system to assist in diagnosing laptop damage based on symptoms inputted by users. The system is developed using the Forward Chaining algorithm, a data-driven reasoning method that matches facts (symptoms) with a set of predefined rules to conclude the type of damage. The system is built using the Waterfall development method, assisted by UML diagrams, and implemented with PHP programming language and MySQL database. Blackbox Testing is used to evaluate the system’s functionality. The results show that the system can be used as a supporting tool to help both users and technicians perform initial laptop damage diagnosis more quickly and efficiently.

Abstract

The administrative and community service processes in RW 10 Rawabugel, Bekasi City, are still carried out manually, resulting in delays in service, long queues, and difficulties in managing community data and archives. Therefore, a system is needed to improve the efficiency and quality of service. This study aims to design and develop a web-based administrative and community service system by applying the Queue algorithm using the First Come First Served (FCFS) method. This system allows residents to submit service requests online and monitor the status of their requests in real time, while RW officials can manage data and archives in a structured and computerized manner. The use of the Queue algorithm serves to automatically and fairly arrange the order of services based on the time of submission. The results of the study show that the developed system has succeeded in increasing service efficiency, reducing queue backlogs, and facilitating the management of resident administrative data. This system is expected to be a solution in improving the quality of administrative services in the RW environment.

Abstract

Indoor air quality monitoring is important in workplaces because hazardous gas exposure may occur without clear sensory indications. This study developed an Internet of Things based air-quality monitoring system by integrating an MQ-135 sensor, an ESP32 controller, an LED Matrix P10 local display, and the Ganesha16 web monitoring platform. The novelty lies in the simultaneous delivery of environmental information through a local public display and remote web access within one integrated architecture. The system was developed using the Prototype method, covering requirement analysis, system design, prototype implementation, functional testing, evaluation, and refinement. Continuous testing was conducted for three days in a workplace environment and produced 1,090 monitoring records. The mean Air Quality Index was 41.84, classified as good, while all five functional scenarios, including sensor reading, data transmission, LED Matrix display, web monitoring, and real-time communication, operated successfully. These results show that the proposed architecture can support accessible real-time indoor air-quality monitoring. However, because MQ-135 responds to several gases, the prototype is more appropriate as an early air-quality monitoring system than as a precision instrument for carbon monoxide concentration measurement.
