Based on the results of the analysis and design that has been carried out regarding the study of electronic-based North Sumatra KUMKM community development analysis (E-Community KUMKM North Sumatra), a conclusion can be drawn as follows, namely the results of the design using the Object Oriented Analysis Design (OOAD) method, all interfaces are designed very interactive so as to facilitate implementation in the system. Using UML as a visualization medium for system design can make the designed model closer to reality. So as to facilitate the development of the system and its application. Based on the results of the analysis using the Performance, information, economic, control, efficiency, service (PIECES) method, the limitations in marketing the results of North Sumatra KUMKM can be solved using information technology, namely the web-based KUMKM E-Community system.

Monitoring systems have undergone numerous developments and improvements. Smart-home monitoring is one of the categories of monitoring systems which can be accessed remotely. Rice monitoring is one type of smart-home based monitoring that can be performed. In order to prevent households from experiencing a sudden lack of rice stock, it is essential to closely monitor the stock of rice. The Smart-home Based Rice Monitoring Design is an innovation created by earlier researchers for the benefit of the community, particularly households. This system is constructed with a microcontroller and a load cell sensor. To operate this device, user enters the weight of the rice using the keypad, and presses the fence button to release the rice from the container. In the meantime, pressing the star button on the keypad will delete or clear the entered numbers. The servo will then operate to open the valve, allowing the rice to fall, and close the valve when the weighing process is complete. A load cell sensor will perform the weighing process, and a 16x2 LCD will display the rice weight output process. All data processed through ESP32 will be transmitted to Firebase. The development of the application was planned using the MIT App Inventor website. To create applications on MIT App Invertor and Realtime Database on Firebase, an internet connection and an active email address are required.

Kemampuan kognitif siswa terutama di tingkat SD adalah salah satu kemampuan yang ingin dibangun melalui pembelajaran kurikulum Merdeka Belajar. Walaupun pada kurikulum Merdeka Belajar kemampuan kognitif tidak memiliki porsi yang besar, namun sangat dibutuhkan untuk memenuhi kebutuhan belajar di jenjang pendidikan dasar salah satunya adalah mata pelajaran Matematika. Tujuan pelaksanaan PKM ini adalah untuk membantu para guru di SD Yayasan Mulia meningkatkan kemampuan kognitif siswa dengan memberikan pelatihan mandiri bagi siswa yang belajar dari rumah menggunakan aplikasi. Pada kegiatan PKM ini akan menerapkan Aplikasi pembelajaran mandiri bagi siswa berbasis Windows® dan android®. Aplikasi akan dibagikan kepada orang tua siswa oleh para guru.  Pada aplikasi ini akan terdapat gambaran perkembangan anak dalam menyelesaikan permasalahan menggunakan soal-soal yang diberikan oleh guru.  yang diikuti dengan pelaksanaan evaluasi untuk mendapatkan hasil yang maksimal. Untuk mendapatkan hasil evaluasi, aplikasi akan dihubungkan dengan aplikasi yang terhubung ke aplikasi web berbasis API (Application Programming Interface). Pelatihan akan diberikan kepada para guru agar dapat mensosialisasikan kepada para orang tua mengenai tata cara penggunaan aplikasi.

The IoT-based catheter monitoring system (Sismoniterin) is a system created to assist health workers, especially nurses and the patient's family, in monitoring the height of the contents (volume) of the catheter so that there is no leakage in the patient's urinary catheter due to excess storage capacity. This system uses a water level sensor to detect the urine level on the patient's catheter and the NodeMCU ESP 8266 as a microcontroller that will help the sensor to send data, namely the patient's urine on the catheter via the internet, and can also apply the IoT concept which can monitor the patient's catheter automatically. The results of this study are in the form of a system that can send notifications via whatsapp nurses regarding the volume of the patient's catheter. Besides being equipped with quite a lot of output, this system uses a rechargeable lithium battery. However, the drawback of this system is that this system is not equipped with an LCD to see the remaining battery working on the system so that the nurse must prepare a backup battery if the battery system is being recharged, so they can use a spare battery to be able to operate the system...
