The wireless communication system is a well known and a standard technology. However, the system performance is highly dependent on the channel fading between transmitter and receiver. Therefore, there is a transmit diversity technique such as Multiple Input Multiple Output (MIMO) to reduce fading effect.One of the transmit diversity technique is Orthogonal Space-Time Block Code (OSTBC). OSTBC is a transmission channel coding technique with multiple transmitting and receiving antennas. The principle of OSTBC is to send multiple copies of the information signal from a data stream across some antennas; thus, some of the copies of data received are better than others. After combined with BPSK modulation, a compressed Bot Error Rate (BER) value at 10-3 at 5 dB Signal to Noise Ratio (SNR) was obtained, whereas after combined by QPSK modulation, a BER value at 10-3 at 7 dB SNR was obtained.

Robotic technology that is developing rapidly triggers robotics developers to improve their abilities, especially in the field of robot control and monitoring. Today, robots are indeed present in human life in various forms. One type of robot that is often developed by robotics developers is the Industrial Mini Manual Robot. An industrial mini manual robot is a transporter robot that is equipped with a gripper and is controlled manually by the user through a joystick controller both wired and wireless. The manual robot with cable joystick control is very inefficient in its use so research on wireless joysticks is carried out. However, the current wireless joystick still uses the single-channel method, thereby eliminating multitasking capabilities such as those of the wired joystick robot. In this research, the design of multichannel transceivers for control and monitoring so that the robot has the ability to multitasking and the movement of the robot is not disturbed by wires. Multichannel transceivers use different frequency channels to transmit data. The command data and monitoring data can be transmitted simultaneously. This multi-channel transceiver has an average pairing time of 23.59 ms, a range of 116 meters in each channel and large power consumption of 59 mA.

Increasing demand for electricity also implies a rise in conventional energy use, and by using conventional energy, leading to disadvantages such as being environmentally unfriendly as a result of fossil fuel use. The system to be researched is a wireless intelligent power switch. The system will be created using 2 types of resources and each load will be linked to a switch to determine the power distribution. The power distribution decision making involves an artificial intelligence-based on backpropagation neural network. The results of the comparison between the outcomes of Matlab simulation and the anticipated target showed excellent outcomes after testing the system, with accurate 94.3% and delay transmission 5 â€“ 10 second.

The local water supply corporation in Indonesia only uses analog water meter so that the monitoring of water usage information was conducted by officers manually. Officers must physically monitor the value in the customer's water meter that can lead to unreliable reading and ineffectiveness of process. Smart meter is one of the smart city metrics which could overcome this problem. This research uses the flow sensor to design and incorporate automated water meters. The measured value is then passed via the 433 MHz LoRa, a low-power wide-area network protocol, to the local hub, then forwarded to the server via the internet based cellular network. Results show that our proposed system's accuracy hit 97.31% at an ideal distance of 200 meters from customer to the local hub. The customer's water usage could be tracked in real time with our proposed system. Furthermore, the original water meter need not to be replaced which may minimize capital costs for this system.

A structure due to natural disasters often occurs in Indonesia, and this is caused by the location of Indonesia in the path of earthquakes and volcanoes. Logistics delivery in the form of medicines and food has been hampered, and this is acknowledged by the Indonesian government, which experienced many obstacles when it had to reach an isolated location due to land transportation lines being cut off. So it was designed an Unmanned Aerial Vehicle (UAV) or drone that can deliver survival kits to some places that are isolated due to natural disasters autonomously. Flight orders will be made through the Mission Planner software, which is then sent to the drone using 433 MHz telemetries. Survival kits carried by drones will be dropped using a servo to a predetermined location. The work of Vertical Take-Off Landing (VTOL) for Drop Kits has successfully carried out a mission to deliver survival kits to 4 different locations in one flight. By using the 433 MHz Telemetry, the drone can travel a maximum distance of 120 meters in 5 minutes 10 seconds with a 9 Ah battery capacity.

In the cultivation of teak plants often have problems because teak seeds have a thick and hard skin or impermiabel (difficult to penetrate) to water and gas so as to slow germination. The magnetic field can increase the growth rate in inactive seed seeds because the magnetic field affects the physical and chemical properties of water as a germination medium. Water exposed by the magnetic field can be absorbed easily with tissues in the seeds, thus shortening seed dormancy and increasing the percentage of seed germination. This study aims to understand the growth process of dormancy seed germination, To know the influence of magnetic fields on the growth of teak seed seeds, as a solution to the problem of seed dormancy in teak seed seeds. Therefore, the method used in this study is to provide exposure to teak seeds and make tools for monitoring teak growth in real time with the parameters of planting media moisture (to see the absorption of water) and high seeds (for the growth of teak seeds), so that used YL69 sensor for soil moisture and sharp infrared sensor gp2y0a02yk0f for high plants.

People want a vehicle that is ready to use without having to wait for long or in the sense that the performance of an activity can run efficiently. With a remote control that can control the vehicle remotely, activities in setup mode will be more efficient. In general, remote control is used in motorized vehicles using Infra-red or Bluetooth communication with communication distance 60meters. So we need LoRa module that has longer beam range. The purpose of research is to design remote control and receiver that can control the vehicle such as opening vehicle door lock, activating the AC, to the starter mode on the car contact with a wider range of sending and receiving information. The results of research indicate that LoRa module has received signal strength value (RSSI) of -65dBm when LOS (line of sight) at distance 10meters and RSSI of -66dBm at non-LOS (non-line of sight) at the same distance. SNR of 9.25dB when LOS and SNR of 6.0dB when non-LOS at distance 10meters. The research results of sending and receiving remote control data have a maximum distance when non-LOS with obstacles 5mm thick glass and 20 cars is 100 meters with a received signal strength of -112dBm. It can be concluded that for non-LOS connectivity between the LoRa SX1278 has an effectiveness distance at 50meters with an RSSI value of -99dBm and an SNR of 0.25dB, for a LOS condition it has an effectiveness at distance 50meters with RSSI value of -96dBm and SNR of 9dB.
