Smart Aquaponics Monitoring and Control System Using Internet of Things Technology

2023-07-06T00:53:35+00:00

Aquaponics is an integrated farming system that combines fish farming (aquaculture) with plant cultivation (hydroponics) in a mutually supportive environment. Aquaponics provides an attractive solution in terms of limited land use in urban areas. In its development, the use of Internet of Things (IoT) technology has made a significant contribution in increasing the efficiency and success of aquaponic systems. The method used in this study is to utilize sensors connected to the IoT network, such as ultrasonic and DHT22 sensors to collect data on important parameters in the aquaponic system, such as temperature and water level, and humidity. The sensor will provide information to the Arduino Uno microcontroller, then the microcontroller will order the water pumps, lights and fans to turn on or off. This system is also equipped with a user interface that allows users to monitor and control the aquaponic system in real-time via a mobile device.

Analysis And Design Of A Website-Based Information System For Educational Development Contribution Payments (Spp) At Smks Yapenap

2026-02-12T02:38:19+00:00

SMKS Yapenap still manages tuition fee payments manually using spreadsheets, which increases the risk of recording errors and slows down report preparation. This study aims to analyze and design a website-based tuition fee payment information system to improve operational efficiency and data accuracy. The methodology used is Rapid Application Development (RAD) with Unified Modeling Language (UML) modeling. System requirements analysis is also supported by the PIECES framework to evaluate performance and service aspects. The results of the study are a system design with a centralized database that enables real-time data management. An automatic validation feature is designed to minimize human error and speed up the transaction process. In addition, this portal provides transparency for parents in monitoring payment status independently. In conclusion, the RAD method is effective in producing a professional and accountable financial management solution for SMKS Yapenap.

Usability Assessment of the KAIA-PAY Application Using Nielsen's Usability Attributes Model

2023-07-08T07:08:10+00:00

Web browser applications such as KAIA-PAY have become a major requirement in the digital
era for credit agent users. KAIA-PAY facilitates users in serving credit purchases and getting
information easily. Although many users were satisfied with the app's performance, some users
also expressed their dissatisfaction. Therefore, this study aims to evaluate usability using the
Nielsen Usability Model in the KAIA-PAY application to assess user satisfaction and identify
existing usability problems. Evaluation includes aspects of ease of learning (learnability),
efficiency (efficiency), user's ability to remember (memorability), error rate (errors), user
satisfaction (satisfaction), usability (usability), conformity to specifications (Conformity to
Specification), and Responsiveness (Responsiveness). The collected data was analyzed using
the Smart PLS 4 application to understand the level of usability of the KAIA-PAY application
and the factors that influence it. The results of the study found that KAIA-PAY was
significantly influenced by the Learnability and Satisfaction variables.

User Interface and User Experience Design of a Tourism Information System for Bima Regency

2026-06-03T01:23:55+00:00

Bima Regency has diverse tourism potential, including natural, cultural, historical, and marine tourism, supported by accommodation and tourism businesses. However, tourism information is still distributed across several platforms, is not centralized, and is not presented completely. This condition makes it difficult for local communities and tourists to obtain information about destinations, facilities, road access, accommodation, events, and tourism news. This study aims to design the UI/UX of a web-based tourism information system for Bima Regency using the Design Thinking method. The research stages include empathize, define, ideate, prototype, and testing. Data were collected through interviews with the Bima Regency Tourism Office and 20 respondents, then analyzed using empathy maps, user personas, affinity diagrams, How Might We, site maps, user flows, and prototype design using Figma. The prototype was evaluated using the System Usability Scale (SUS) with 56 respondents. The resulting prototype includes destination, event, news, accommodation, detailed tourism information, and admin pages for managing tourism content. The SUS test produced an average score of 84.55, categorized as acceptable, grade B, and an excellent adjective rating. These results indicate that the UI/UX design has good usability and can be used as a reference for developing a tourism information system in Bima Regency.

Implementation of Forward Chaining in a Web-Based Expert System for Diagnosing Chili Pepper Plant Diseases

2026-03-30T01:56:16+00:00

Chili plants are among superior horticultural commodities with high economic value and play a crucial role in supporting the agricultural sector in Indonesia. In cultivation practices, chili productivity often declines due to infections caused by various plants diseases. This condition is futher exacerbated by farmers limited technical knowlegde and insufficient accsess to agricultural experts, which frequently caused delays in the diseases identification process. This study aims to develop a website based expert system to assist in diagnosing chili plant diseases by applying forward chaining method. The system operates by processing facts input by users to generate appropriate diseases diagnoses and teatment recommendations. The system’s knowlegde base was constructed through literature studies and interviews with agricultural experts, and was represented in the form of IF-THEN rules. The testing results indicate that the expert system is capable of accurately identifying types of diseases iaffecting chili plants and providing relevant handling recommendations. Therefore, the proposed system is expected to support chili farmers in making more effective decisions, thereby improving chili crop productivity.
