Abstract

LoRa is a long-range communication technology with the advantage of wide coverage but faces challenges in single-hop communication. This issue arises because the communication occurs in Non-Line of Sight (NLOS) conditions. The method used to address this is by testing a multi-hop LoRa communication system, where relays act as intermediaries between the transmitter and the gateway. The results from this study show that communication between the transmitter and relay 1 maintains a consistent RSSI of -94 dBm with an SNR ranging from 8.25 dB to 10 dB. Communication between relay 1 and relay 2 has an RSSI ranging from -83 dBm to -86 dBm and an SNR between 7.50 dB and 9.50 dB. For communication between relay 2 and relay 3, RSSI ranges from -105 dBm to -116 dBm with an SNR between 3 dB and -8 dB. Communication between relay 3 and the gateway shows an RSSI between -94 dBm and -97 dBm with an SNR between 2.00 dB and 2.50 dB. The multi-hop LoRa system successfully detected and transmitted fire data in real-time, including smoke concentrations rising to 85 ppm, with smoke and fire indicators both showing a value of 1, indicating the presence of a fire, as well as changes in temperature and humidity. The system consistently detected and transmitted fire data accurately under various conditions, with sensor data from the transmitter reaching the gateway without loss or damage.

Abstract

Indonesia is an agricultural country that produces rice plants. The decline in crop yields was caused by pests and had an impact on rice plants which experienced yellowing leaves, broken stems, until the rice fruit became empty. Test results data in the form of numbers in certain units will be presented in the form of tables and graphs. To find out the symptoms or behavior of the system at the time of testing, an analysis is carried out. The research was conducted for 5 nights starting at 18.00 until 06.00 WIB. The LoRa sender will send data when a pest lands on a 1000-1500 VDC wire net. In the research conducted, a total of 97 pests were found. The peak of pest attacks occurs at 19:00 to 20:00 WIB. Walang sangit attacks rice plants in all phases, so it is not surprising that this pest has the largest number, namely 87 pests. The rain that falls makes the lights dim thereby reducing the interest of the pests in the pest traps. Lamps with a wavelength of 500 nm can attract the attention of nocturnal pests that attack rice plants at night.

Abstract

The output power generated by the photovoltaic module and its lifetime depend on many aspects. Some of these factors include: type of PV material, intensity of received solar radiation, cell temperature, parasitic resistance, clouds and other shadowing effects, inverter efficiency, dust, module orientation, weather conditions, geographical location and cable thickness and others. There are several environmental parameters that can affect the performance of solar cells, including changes in temperature, intensity of solar radiation, partial covering of the surface of the solar cell. Partial covering of the solar cell surface is usually caused by dust adhering to the solar panel for a certain period of time or it can also be caused by animal droppings such as birds that accidentally hit and cover the surface of the solar panel. Because it causes the closing of the solar cell, the performance of the solar cell will not be maximized, so it can greatly affect the decrease in the value of the output power and also the current generated. But how big the resulting influence is not yet known. The data logger managed to record the necessary parameters of the PV circuit that is applied to the shadow, namely, Voc voltage, working voltage, working current and power. The application of a rectangular shadow pattern has differences from a circle pattern, namely: in a rectangular pattern: a significant voltage drop occurs when the shadow is applied by 60%, the PV can still emit current although it is relatively small, the PV no longer emits voltage when the shadow is more than 70% , whereas in the circle pattern: the PV voltage starts to drop after the shadow is applied by 30%, if the shadow is more than 30% then the PV is no longer flowing current.

Abstract

In wireless communication, the success of information exchange is a critical aspect, evaluated based on parameters such as Packet Delivery Ratio (PDR) and packet loss. Several factors, such as antenna gain, antenna height, and transmission distance, if not appropriately configured, can result in a small packet data ratio due to the loss of packets in wireless communication, leading to a lack of received information. Therefore, research has been conducted to identify and understand the causes of a small packet data ratio due to packet loss. The results obtained from this research show a Packet Delivery Ratio (PDR) of 100% and packet loss of 0% with the use of a 3 dBi gain antenna, which is only able to reach a distance of 400 meters. Meanwhile, the use of a 5 dBi gain antenna can reach a distance of 800 meters. Increasing the gain antenna can enhance the transmission distance. In terms of antenna height variation, a 3 meter height achieves a Packet Delivery Ratio (PDR) of 100% and packet loss of 0%, covering a distance of 600 meters, while the use of a 6-meter antenna height can reach a distance of 800 meters. Increasing the antenna height can improve the transmission distance.

Abstract

This research investigates blank spot areas on the GSM network in Rasau Jaya District with an emphasis on several roads. The drive test method and G-Nettrack application are used to identify and measure signal quality, especially RSRP (Reference Signal Received Power), from three main providers: Telkomsel, H3I, and Indosat. The research results reveal significant variations in RSRP values in blank spot areas on primary and secondary roads. On primary road Telkomsel providers with signal categories are: Very Good 77, Good 237, Not Good 227, Very Bad 465. Indosat Ooredo Primary Road, Very Good 118, Good 462, Not Good 356, Very Bad 200, H3I Primary Road , Very Good 118, Good 230, Not Good 409, Very Bad 175. Then data Telkomsel Secondary Road Very Good 60, Good 287, Not Good 75, Very Bad 1232. Indosat Ooredo Secondary Road, Very Good 122, Good 102 No Good 158, Very Bad 1372, H3I Secondary Road, Very Good 117, Good 135, Not Good 145, Very Bad 1362. Data analysis confirms that the further the measurement distance from the Base Transceiver Station (BTS), the signal quality tends to decrease, especially in the very bad category. Identification of the distribution of blank spot areas also provides insight into locations that require signal improvement, providing a basis for improvement steps in developing the GSM network in the region.

Abstract

The development of wireless network technology, particularly WiFi 6 at 5GHz, offers greater reliability and data transfer capacity. Antenna design is a crucial aspect in optimizing WiFi 6 networks in complex wireless environments. The study examined a rectangular patch 2x2 MIMO Antenna for WiFi 6 at 5GHz with a focus on improving network parameters such as return loss, bandwidth, VSWR, and gain. The use of various methods and references from Balanis (2005) and Webster (2021) supports the development of antenna technology, while previous research by Ni Putu Kartika Dewi (2019) strengthens the understanding of microstrip antennas for LTE applications. The main objectives of the study were to design and simulate a rectangular patch 2x2 MIMO Antenna for WiFi 6, as well as analyze simulation data using CST Studio Suite 2019 software. This research uses hardware in the form of Acer Aspire laptops and CST Studio Suite 2019 as simulation software and antenna design. The simulation results show that this antenna is able to work in the frequency range of 4.5-5.2 GHz with a bandwidth of 55.4 MHz and return loss of -20.677981 dB, VSWR 1.2038357, and gain 3.429 dBi with omnidirectional radiation patterns. However, the addition of antenna patches has an impact on decreasing gain. This study provides an in-depth understanding of MIMO antenna design to support WiFi 6 performance in complex wireless environments.

Abstract

Electrical energy distribution systems are essential for modern life, especially in communal homes that use energy significantly. Monitoring and measuring the difference in electrical energy between pole substations and communal houses is important for cost efficiency and environmental sustainability to avoid misunderstandings between customers and electrical energy providers. Therefore, remote communication technology and the Internet of Things allow in real-time and accurate monitoring. In this study, the stages of collecting electricity parameters were carried out. The method of observing electrical power uses a current sensor (SCT-013) and a voltage sensor (ZMPT101B). The ESP32 microcontroller is used in measurement systems and as a link to the internet connection via a Wi-Fi network. The measurement data is stored in the data logger with txt format. The Internet of Things media platform used is a website-based Thinger.io. The test results show that long-distance energy difference monitiring can be done and send the parameters of voltage, current, power and energy in the form of kWh by Tx_1, Tx_2, Tx_3 and Rx to the thinger.io with periods every 5 seconds alternately. Then data was taken and the value for the total current was 5.66 A, the total power value was 1077.66 W, the energy value at the source was 10.78 kWh, so that the energy difference value from the three transmitters and the source was 0.18 kWh with an error value in the energy difference of 1.704%.
