Abstract

Kerupuk merupakan makanan ringan yang banyak digemari oleh masyarakat. Pengolahan kerupuk yang dilakukan oleh UKM di Indonesia masih dilakukan secara konvensional, mulai dari pembuatan adonan hingga pemotongan adonan. Hal ini tentunya mengakibatkan produktivitas dan kapasitas produksi rendah. Untuk meningkatkan produktivitas perlu adanya penerapan teknologi tepat guna yang dapat digunakan dalam proses produksi. Tujuan penelitian ini untuk menghasilkan mesin pemotong kerupuk semi otomatis guna meningkatkan produktivitas dan kapasitas produksi melalui penerapan teknologi tepat guna. Metode penelitian yang digunakan ialah riset development yang terdiri dari: (1) Identifikasi kebutuhan terkait spesifikasi mesin yang akan dibuat, (2) Pembuatan alternatif desain dengan menggunakan bantuan software Computer Aided Design (CAD), (3) Pemilihan desain mesin yang akan dibuat, (4) Proses pembuatan mesin, dan (5) Pengujian mesin. Mesin pemotong kerupuk ini dirancang semi otomatis yang memiliki kapasitas output 60 kg/jam yang dapat memotong adonan kerupuk dengan dimensi panjang dan ketebalan sebesar 120 mm x 4 mm. Berdasarkan hasil pengujian, mesin tersebut dapat memotong kerupuk dengan baik dan sesuai dengan dimensi yang diinginkan. Hasil penelitian menunjukkan bahwa terjadi peningkatan kapasitas produksi sebesar 200%.

Abstract

To support the management of large-scale area potential such as rural spatial planning, Kaligentong Village uses area mapping as an effort in village development planning. The mapping is displayed in paper media which has limited access so that this is inefficient and hinders the Kaligentong Village government in managing the assets and potential contained in it. Therefore, an information system is needed that can monitor the assets and potential of Kaligentong Village in the form of web-based digital maps and android. This study aims to create a dynamic digital mapping of villages for Kaligentong Village so that it is more efficient in finding and managing information related to geographical conditions and potential of Kaligentong Village. The method used is waterfall which consists of the stages of analysis, planning, modeling, construction, and testing. The system is built using javascript leaflets, native PHP, QGIS, and MySQL databases. Based on data from black box testing, the village digital map application runs according to the functional system. The satisfaction rate of application and web users is 94.10%. The average response time per activity generated by the application was 1.44s at 96 Mbps bandwidth and 0.89s at 144 Mbps bandwidth for websites.

Abstract

Temperature and humidity are aspects that need to be considered in cultivating oyster mushrooms. Previously, Fungi House in Genting Village, Semarang, implemented an automatic temperature, humidity, and watering monitoring system, but manually filled the water. This new system's design and development aim to simplify the monitoring and control of temperature, humidity, and water level for managers. Managers determined temperature, humidity, and water level thresholds via the web page. This system used the agile scrum method. The test results showed that the temperature measurement accuracy was 96.85%, humidity 99.35%, and water level 98.99%. With this system, the quality of baglog (mushroom growing medium) increased by 4.62%, while dead baglog decreased by 99.01%. Black box testing demonstrates that all features perform well in web testing. In the load activity test, with low bandwidth (6.71 Mbps), the average load time was 1.32 seconds, and with high bandwidth (37.15 Mbps), it was 0.878 seconds. These two conditions indicate excellent system performance and provide optimal user experience.
