Abstract

One of parameters for observing weather elements is the amount of rainfall. The rainfall observation system is using ARG. The existing condition uses cellular network-based IoT. In this study, researchers tried to provide an alternative communication system for ARG data acquisition networks using LPWAN-based IoT technology. Comparison of three LPWAN IoT technologies that can be applied to ARG communication systems, namely NB-IoT, Sigfox, and LoRaWAN. The three LPWAN technologies have followed the Republic of Indonesia Minister of Communication and Information Regulation No. 1 of 2019. These three technologies can be used for ARG data acquisition networks. LoRaWAN technology in rural areas reaches 20 km. LoRaWAN devices that meet frequency requirements have been sold freely on the internet with the 920 MHz frequency band. Of these three technologies, only LoRaWAN can be used to build private or internal communication networks. This is an added value for BMKG to build district or provincial scale LPWA WAN networks in regions that are constrained by the transmission of ARG data through cellular networks.

Abstract

An official weather forecast dissemination application named @infoBMKG developed for Android and iOS by BMKG available since 2016. Following users behaviour on instant messaging service application, system development is necessary needed for accommodating request-based dissemination. The Telegram Bot feature with Webhook method is applied because of the efficiency on coding for initial setup in the development of Telegram Bot. Therefore, it allows fast response in sending reply to any request. There are three main menus in the design of the telegram Bot (@BMKGbot) displayed as Weather Forecast, Airport Weather, and Satellite Imagery. As results of performance testing, the average response time dissemination-request 2.54s for Weather Forecast, 2.76s for Airport Weather and 7.28s for Satellite Imagery. Bigger size of data disseminated in an image format of satellite imagery cause longer response time, however the performance testing obtain response times within satisfactory period and meet as expected. It is recommended to implement @BMKGbot at reliable hosting service on its operational environment for chasing users’ satisfaction with high availability services in term of weather forecast dissemination.
