Abstract

Academic information services are information services that are very important for the academic community, and greatly affect student satisfaction in their use because the management of information data for academics is something that is absolutely necessary for educational institutions such as universities.The purpose of this research is to create a new academic information service that will be developed using chatbots on the WhatsApp application, especially in the UIN Alauddin Makassar Information Systems Study Program. Academic information services were developed to be able to access information for members of the Information Systems study program such as student status (view student status), payment (view payment status), KRS (view KRS status), schedule (view class schedule), IPS (see history IPS), Ipk (see GPA history. The type of research used is applied research with a quantitative approach. System development uses the waterfall method, then the system is designed using Unified Modeling Language (UML) data. The programming language used is JavaScript. System testing with Black box testing.Research conducted to create an academic information service system using chatbots has a good effect of 76.4% on the ease of obtaining inform

Abstract

Monitoring agricultural land is a crucial element in increasing productivity and food security. Gowa Regency has extensive and scattered rice fields, necessitating an efficient and affordable automated monitoring system. This study designed and evaluated a wireless sensor network (WSN) prototype based on Arduino and XBee modules to monitor land conditions in real time, including temperature, air humidity, and soil moisture. The evaluation included network coverage, connection stability, sensor accuracy, and the system's ability to support environmental data-driven decision-making. The results showed that the prototype was capable of transmitting data in real time with low deviation, demonstrating the potential of WSN as an agricultural monitoring tool in Gowa Regency

Abstract

including within household environments. However, the presence of areas without signal coverage, or dead zones, remains a serious obstacle in the use of conventional router-based wireless networks. This study aims to evaluate the effectiveness of implementing a Mesh Wi-Fi network in addressing dead zone issues in residential settings, taking into account room configuration, wall obstructions, and potential interference. The research was conducted using an experimental approach by deploying Wi-Fi 6–based Mesh Wi-Fi devices in a two-story house that previously experienced connectivity issues. Data were collected through measurements of signal strength, download and upload speeds, latency, and network stability across three critical areas of the house. The results show a significant improvement, with an average increase of 26.05 dBm in signal strength and more than a 500 percent increase in download speeds after the implementation of Mesh Wi-Fi compared to a single-router network. In addition,the variation in signal quality across locations decreased, indicating a more even distribution of network coverage. These findings demonstrate that Mesh Wi-Fi is an effective and practical solution for improving network quality in homes with complex building structures, and it is capable of overcoming the limitations of traditional solutions such as signal boosters or additional routers. Therefore, the implementation of Mesh Wi-Fi is recommended as an alternative for providing stable internet connectivity in modern households.
