For agate gemstone craft MSMEs in Tunjungmuli Village, whose products possess high economic value due to their aesthetic appeal and rarity, adopting an information system is a strategic way to expand market reach. However, reliance on conventional marketing methods has limited sales growth and market accessibility. This Research and Development (R&amp;D) study employed the ADDIE model to develop an e-commerce system integrated with product information, automatic shipping cost calculation through the RajaOngkir API, and the Midtrans payment gateway, while also evaluating its feasibility. The results show that the e-commerce platform was successfully developed. Evaluation using the Black Box Testing method yielded a system functionality score of 84.6%, which falls within the 81%–100% range and is categorized as Highly Feasible. The findings indicate that minor input-related issues do not affect transaction stability, making the system suitable for optimizing sales among agate gemstone artisans in Tunjungmuli Village.</p> 2026-06-05T17:10:01+07:00 Copyright (c) 2026 Andi Badrun, Anisa Lutfiyani (Author) https://www.jurnal.politeknik-kebumen.ac.id/E-KOMTEK/article/view/3174 Design and Development of a Hydroponic Growing Media Monitoring System for The Growth of Melon Plants from Flowering to Harvest Based on The Internet of Things (IoT) 2026-06-13T02:51:40+07:00 Danang Dasa danangdasa46@gmail.com Aulia Desy Nur Utomo danangdasa46@gmail.com <p>Hydroponic melon (Cucumis melo L.) cultivation requires precise environmental parameter monitoring to achieve optimal results. This study aims to design an Internet of Things (IoT)-based monitoring system to monitor temperature, humidity, pH, and TDS in real-time via a website. The system was developed using the Prototype method with Arduino Uno and NodeMCU ESP8266 as the main controllers. The testing phase included system functionality testing, sensor calibration, and User Acceptance Testing (UAT). Technical testing results showed that the average accuracy of the DHT11 temperature sensor reached 96.61%, the pH sensor 99.67%, and the TDS sensor 64.67%. Meanwhile, the UAT results indicated a system feasibility level of 89.33%, categorized as "Very Feasible." System implementation over 8 weeks demonstrated an improvement in harvest quality, where monitored plants had an average fruit weight of 1.398 kg and a sweetness level of 13.25 °Brix, outperforming unmonitored plants which recorded an average of 1.379 kg and 12.75 °Brix. In conclusion, this system effectively provides measurable data, is feasible for user implementation, and contributes to improving harvest quality.</p> 2026-06-09T13:56:04+07:00 Copyright (c) 2026 Danang Dasa, Aulia Desy Nur Utomo (Author)
