To measure and recognize electricity use in a place immediately, we use a tool called a smart meter, which is part of the Internet of Things (IoT), to provide control and optimization of electricity. Smart meters will operate using LoRaWAN network connectivity as a LoRaWAN communication protocol that supports IoT use at a frequency of 920-923 MHz using coverage planning and capacity planning using Forsk Atoll 3.3.2 simulation software. The parameters used in this study are Spreading Factor (SF) 7, Code Rate (CR) 4/5, Bandwidth 125 kHz, Signal to Noise Ratio (SNR), and Reference Signal Received Power (RSRP). We use them to obtain the number of gateways needed to optimize the scope of gateways for sending electricity monitoring data to Karawang Industrial Estate and knowing the value generated from the parameters above. The simulation of LoRaWAN planning resulted in RSRP with a mean of-77.94 dBm and a standard deviation of 8.27 dBm. The SNR result has a mean of 13.14 dB with a standard deviation of 9.68 dB. The last parameter is that throughput ranges of 4-6 kbps with a mean of 5.47 kbps. The result of this planning produces RSRP, SNR, and Throughput parameter values in good condition to be applied to the application of smart metering in Karawang Industrial Estate. Index Terms—LoRaWAN, spreading factor, gateway, smart meter, karawang industrial estate, IoT I. INTRODUCTION The rapid development of technology has made technology an important need for society. The use of technology is now not limited only to the world of telecommunications. It was used widely in industry, agriculture, health, security, and other fields. In the era of globalization, the internet will synergize with electronic devices to help human activities [1]. The development of the Internet of Things (IoT) used to support human activities to be more effective and efficient to minimize human beings' work. IoT applications are used to monitor aspects such as the energy needed in everyday life, such as electrical energy. Electrical energy is one of the energy sources often used in daily life in Fig. 1, both for lighting, household appliances, industrial equipment, hospitals, and other uses in large quantities. Fig. 1. Electrical energy in daily life [2] The International Energy Agency has reported that energy demand worldwide grew by 2.3% in 2018, the fastest pace in the past decade. Global electricity demand grew by 4% in 2018 to more than 23,000 TWh [3]. The preservation of electrical energy needs to be done considering Indonesia is one of the most wasteful countries in electricity use. In 2010-2014 the average growth of power generation capacity was around 6.5% per year. It occurs due to a lack of public awareness and austerity efforts, such as turning off lights during the day. The problem of wasteful electricity use also occurs in large industrial fields with many workers and machinery,. According to the data statistics of the State Electricity Company (PLN) 2013, in the industrial sector with only about 0.1% of the total customers, the electricity consumption reached 31.59% of the total consumption [4]. The solution is to apply smart metering to avoid excessive use of electrical energy and affect the production budget. Smart metering is a part of the Internet of Things, which can measure, collect, analyze, allow users to check the usage and bill of electricity, and distribute energy and its consumption. Fig. 2 shows that LoRaWAN can be used for IoT connectivity in smart metering, whether it's for electricity, water, or gas. To forward messages or data to the destination, end nodes will be connected to the gateway. Customers must provide accurate data every 15 or 30 minutes to guarantee that electricity energy needs meet Manuscript received August 5, 2021; revised February 17, 2022.
