Abstract

Transmitters are the backbone of communication on wireless sensor networks. Most transmitters use ism band frequencies so the communication range is limited to 100 m. Some types of transmitters that have long-distance communication capabilities are nRF24 1 km and LoRa. The paper reports a comparative study between nRF24 1 km and LoRa in data communication, power consumption and resistance to obstacles. The results showed that LoRa has a range capability of 1.6 km and nRF24 has a delivery capability of 1 km. The 1 km NRF24 is more suitable for long-distance communication that requires high speed and is also resistant to non-line of sight obstacles.

Abstract

Pesatnya kemajuan dunia di bidang Teknologi Informasi (IT) terus berkembang seiring dengan berjalannya waktu. Seiring dengan berkembangnya teknologi dan  ilmu pengetahuan, saat ini media pembelajaran yang sering digunakan adalah media pembelajaran berbasis komputer. Terdapat istilah baru dari kemunculan perkembangan tersebut yaitu media berbasis komputer, yaitu multimedia pembelajaran interaktif. Interaktif berarti terdapat hubungan timbal balik antara media dan pengguna media. Permasalahan yang dihadapi oleh mitra adalah minimnya pengetahuan para guru dalam menciptakan atau mengembangkan media pembelajaran. Hal yang dikeluhkan oleh para guru yaitu keterbatasan media pembelajaran yang mengakibatkan guru cenderung melaksanakan pembelajaran di kelas dengan cara konvensional dan seringnya tanpa media. Oleh karena itu, tim pelaksana mencoba untuk memberikan pelatihan pembuatan Media Ajar Digital sebagai media pembelajaran bahasa Inggris, bahasa Indonesia, Matematika, dan IPA. Bagi guru SDN Muktiwari 01, dengan adanya pelatihan ini diharapkan para guru dapat menguasai pembuatan Media Ajar Digital dan pengisian konten yang positif terkait dengan pendidikan sehingga Media Ajar Digital dapat dibentuk sebagai media untuk aktualisasi diri. Pelaksanaan pengabdian kepada masyarakat dilaksanakan dalam bentuk sosialisasi, Pengenalan, pelatihan, dan praktik penerapan Media Ajar dalam Pengajaran Berbasis Digital kepada guru-guru di SDN Muktiwari 01. Berdasarkan dari hasil pengabdian kepada masyarakat, para guru sangat antusias dalam mengikuti kegiatan pengabdian kepada masyarakat. Para guru sangat senang dengan hasil yang sudah dilaksanakan karena mereka langsung mempraktikkan teori yang sudah disampaikan di hari sebelumnya.

Abstract

The application of WMN and IoT technology to the metering infrastructure is proven to provide convenience in data collection, access to information, and management of metering devices. Unfortunately, the use of this technology is still minimal in developing countries like Indonesia. In this study, the development of a digital meter reading system that focuses on low-power non-intrusive reading devices and the application of WMS in the water meter reading system is carried out. This system consists of a series of meter reader sensors that are connected mesh to a gateway where meter data can be monitored in real-time and remotely. This sensor circuit is an integrated circuit added to the existing mechanical water meter which allows recording the volume of water consumption digitally. This circuit consists of an optical sensor, real-time clock (RTC), microcontroller, Lora Transmitter, and power supply. The use of solar cells to supply energy for meter reading devices is another interesting aspect of the development of this system. A gateway is a circuit built to bridge the transmission of meter data from a radio-based sensor network to the internet. The result of this research is the establishment of a meter reading system capable of accurately reading water consumption, low power where the meter data is easily accessible using a device connected to the internet. This system has been evaluated for every part of development such as reading water consumption, power consumption, and also communication in the mesh network. The contribution of this research is that it can be used as a reference for developing a digital meter system that is more effective, has low power, and has easy access to meter data
