Abstract

In Indonesia, household electricity consumption dominates at 91.47%, increasing living costs. To tackle this, an Internet of Things based system for monitoring energy and electricity expenditure has been developed, accessible through a mobile app. This employs the PZEM-004T sensor linked to an ESP32 to measure electric parameters such as voltage, current, power, energy, and consumption costs. Gathered data is shown on an LCD and sent to Firebase, syncing with the app for easy monitoring by users. The app also offers features to download data and calculate electricity costs for varying periods. Testing of the PZEM-004T sensor showed voltage and current measurement accuracies of 98.5% and 99.89%, respectively, indicating high precision with minimal error. Connected to home appliances, it recorded 0.474 kWh of energy use, costing Rp 640.85. The app displays measurements of five electrical parameters and allows users to download monthly data in Excel format and estimate daily, monthly, and yearly electricity expenses.

Abstract

Pembiasaan Pola Hidup Bersih dan Sehat Guna Memutus Mata Rantai Penularan Covid-19 adalah sebuah kegiatan pengabdian kepada masyarakat yang dilaksanakan oleh Program Studi Broadband Multimedia Jurusan Teknik Elektro PNJ. Kegiatan ini dilandasi oleh kenyataan bahwa saat ini sedang mewabah virus Covid 19 yang sangat cepat penyebarannya. Salah satu penyebab cepatnya penyebaran adalah kebiasaan buruk di masyarakat kita yang belum terbiasa membiasakan Pola Hidup Bersih dan Sehat sebagaimana yang disyaratkan oleh Kementerian Kesehatan RI. Seperti diketahui, virus covid 19 dapat masuk dan menjangkiti manusia adalah melalui mulut, hidung dan mata. Anggota tubuh manusia yang sering menyentuh bagian tersebut adalah tangan. Covid 19 menyebar menjangkiti manusia melalui droplet yang dikeluarkan penderita ketika ia berbicara, bersin atau batuk. Droplet tersebut bisa saja menempel pada benda-benda yang sering disentuh oleh tangan. Tanpa mencuci, apabila tangan yang tidak sengaja menyentuh droplet tersebut digunakan untuk makan atau menyentuh bagian mulut, hidung dan mata, maka kemungkinan besar ia akan tertular. Oleh karena itu sangat perlu untuk dilakukan program pembiasaan pola hidup bersih dan sehat diantaranya adalah mencuci tangan dengan sabun. Untuk mendukung program tersebut maka pada kegiatan pengabdian kepada masyarakat kali ini telah dilakukan pelatihan pembuatan sabun cuci tangan, pemberian tempat cuci tangan portable beserta sabun cuci tangan serta pembagian masker.

Abstract

Kegiatan Pengabdian Kepada Masyarakat sebagai salah satu Tri Dharma Perguruan Tinggi ini bertujuan untuk memberikan perangkat dan pelatihan sistem pembelajaran berbasis multimedia di Sekolah Menengah Pertama Islam Nusantara dan Madrasah Ibtidaiyah Sirojul Athfal 5. Adanya keputusan dari empat menteri (Menteri Pendidikan dan Kebudayaan, Menteri Dalam Negeri dan Menteri Kesehatan) untuk membuka kegiatan Pembelajaran Tatap Muka Terbatas di sekolah mulai bulan Juli 2021, mengharuskan semua sekolah untuk mempersiapkan pembelajaran yang sesuai dengan protokol Covid-19. Pelaksanaan pembelajaran masih dilakukan secara terbatas, sehingga diperlukan metode agar pencapaian materi bisa diberikan sesuai sasaran. Langkah pelaksanaannya diantaranya melalui Pembelajaran Jarak Jauh (PJJ), dimana akan lebih memudahkan guru dan siswa jika menggunakan Learning Management System (LMS). Pelatihan sejenis LMS ini akan memudahkan guru dalam memberikan pengajaran visual secara online, memberikan tugas, mengatur pengumpulan tugas, memberikan ujian baik harian atau pun semester.

Abstract

The rapid development of digital technology has affected many sectors, including the tourism sector. Utilizing digital platforms, such as websites, is an option for promoting tourist areas. Kampung Setaman is an area that has the potential to become an educational tourism destination. However, this village does not yet have a website as a promotional medium for its village. Therefore, this research aims to develop a website for the Kampung Setaman Tourism Village which is expected to help the Kampung Setaman management in promoting the area more widely. Creating a website begins with a needs analysis to find out what menus need to be on the website. Next, the website interface was designed using HTML, CSS, Javascript and PHP, as well as creating a database using MySQL. Collecting and creating website content in the form of writing, photos and videos about the area and programs of Kampung Setaman is also carried out to then be uploaded on the website being developed. The final stage of creating a website is testing performance efficiency and security. Based on performance efficiency testing, an average performance value of 90.2% was obtained. Meanwhile, from security testing using HostedScan, it was found that website security was quite good.

Abstract

A locker is a storage facility that can be seen at several public facilities such as public swimming pools, a library, and sports facilities like a gymnasium. Most lockers at public facilities still use conventional locking techniques. This has a negative impact in terms of effectiveness, efficiency, and security. Therefore, a QR-Code-based system that is integrated with the android application has been created to function for monitoring availability, borrowing lockers, and opening and locking lockers through the android application. Smart locker system using ESP32 as microcontroller and network that used to receive data sent from android application. When data is received, ESP32 will respond by activating the relay which controls the magnetic lock that replaced the conventional lock, while the android application is created for monitoring locker availability, borrowing lockers, and opening and locking lockers through the android application. This test is carried out for this application, which refers to the ISO 25010 standard with aspects of functional suitability, usability, and compatibility. The results of testing aspects of functional suitability and compatibility get 100 percent feasibility percentage results. Then for usability, it shows that from the 10-point questionnaire distributed to respondents, the percentage of feasibility results is 78.98 percent which is included in the acceptable category, this shows that the mobile application has good quality. The system test was done by pressing the button in the android application at the same time with two different devices and having a time difference while opening the lockers with a time average of 0.874 seconds.

Abstract

This community service activity aims to implement an Internet of Things (IoT)-based environmental security system integrated with mobile applications to improve the quality of life of residents in RT 01 RW 03 Beji Timur. The main problems identified include high crime rates and inefficient manual administrative systems. Using the Participatory Action Research (PAR) approach, the system was developed with hardware components consisting of ESP32 microcontroller, DFPlayer Mini module, and PAM8610 amplifier connected through Firebase Realtime Database. The E-RT 01 RW 03 mobile application provides alarm alert feature with queue logic, transparent bookkeeping, digital dues cards, and electronic letter submission. The evaluation results show a significant increase in participants' knowledge from an average score of 74 to 81 after training. Although there was a slight decrease in usage intention (78 to 77) and training evaluation (78 to 76), these values still indicate positive community response. The system successfully provides fast emergency response, administrative transparency, and easy-to-use interface.
