Abstract

The development of fifth-generation cellular technology, commonly referred to as "5G" networks, is believed to be able to maximize data speed access needs. In order to maximize the utilization of the existing 5G network in Indonesia, Telkomsel providers are using a frequency of 2.3 GHz with a bandwidth of 50 MHz. So we need an antenna amplifier that is easy to fabricate and place anywhere to maximize the signal capture range. A microstrip antenna is a suitable antenna for this amplifier. The advantage of this antenna is that it has a light mass and is easy to fabricate. while the drawbacks come in the form of narrow bandwidth and small gains. Therefore, an antenna design with an artificial substrate and array technique was made to overcome this. The design of this microstrip antenna was made in the CST Studio Suite 2019. The design was carried out by entering the antenna dimension values to be simulated and seeing the parameters; if they are not suitable, then they need to be optimized again, and when they are appropriate, the design results are fabricated and printed. In testing the signal capture power using the Xirrus WiFi Inspector, this antenna was able to capture the signal beam, which was 105 meters or 40 meters further than not using the antenna. In addition, from testing, it is known that this antenna has a gain of 16.15 dBi. While in the simulation, it is also known that this antenna has the following characteristics: return loss: -32,353 dB (S11), -32,737 dB (S22), -33,974 dB (S33), -34,423 dB (S44), VSWR: 1,049 (VSWR 1), 1,047 (VSWR 2), 1.040 (VSWR 3), 1.038 (VSWR 4), impedance: 50.7 -111 MHz.

Abstract

Monitoring the electrical energy of the MSME sector is necessary because the current use of electricity is less effective and consumes more electrical power. The use of electrical power can only be seen through the kWh meter measuring instrument and only shows the cumulative amount of electrical energy used. The analog panel design constraint only displays aggregate consumption data, not real-time. This study aims to develop an energy management system through Internet of Things communication for monitoring and controlling electrical devices in MSME sector buildings. Designer of a real-time measurement system that can read the parameters of the amount of electricity consumed so that MSME users can monitor the use of electricity consumption quickly and accurately via the internet and become a solution for more efficient monitoring work. The monitoring system is designed for load groups in buildings by using the ESP32 NodeMCU as a data processor for data received from the PZEM-004T sensor and sent directly to the Blynk server so that the data can be monitored and controlled on the Blynk interface via a smartphone. The data displayed on the Blynk application is in the form of voltage (volts), current (amperes), power (watts), electrical energy (kWh), and electricity usage rates in rupiah in real-time. The results of the study obtained show that the proposed method can read the energy consumption data of the electrical load used with an error value of 0.54% in voltage measurement and an error value of 2.93% in current measurement and has a delay in sending data to the monitoring application of an average of 3 seconds. The proposed draft Energy Management System can improve electricity efficiency if applied to solve the problem of electrical energy consumed in MSME sector buildings.

Abstract

Increasing population and consumption patterns affect the volume, type, and characteristics of waste which vary and increase periodically. This increment must be accompanied by the management of waste transportation so that the accumulation of waste can be prevented. Therefore, it is necessary to design a prototype of a smart dustbin condition monitoring tool that is capable of providing full information and notifying the collector in the form of the location of the IoT-based dustbin. The research method is a prototyping type to obtain a smart dustbin prototype and produces IoT-based smart dustbin hardware and software. Ultrasonic sensors are used to detect objects and measure the height of waste, loadcell sensor measure the weight of waste, and GPS is used to obtain the location of dustbin. NodeMCU ESP8266 processes sensor data and sends it to the user. The results showed that testing of the object detection hardware was able to open and close the dustbin automatically when there was an object at a distance of ≤50 cm. Detectors of height and weight of waste can measure the height and weight of waste with an error of 0.4% and 0.15% respectively. The results of software testing show that the tool succeeds in sending WhatsApp notification data when the waste height reaches 3 cm from the sensor or 4000-gram waste weight, with a Throughput measurement of 327.95 kbps, and takes 2.61 seconds to send a notification message of 69 bytes.

Abstract

Oyster mushroom is one of the favorite horticultural commodities consumed by Indonesian people. In the cultivation of oyster mushrooms, there are many obstacles faced by farmers, including the difficulty in maintaining the temperature and humidity of the kumbung room so that to maintain the stability of temperature and humidity, farmers must always check and do regular watering. With these problems, a temperature and humidity monitoring and control system is needed to maintain the stability of temperature and humidity in oyster mushroom cultivation by automatically watering and heating the room temperature of the kumbung. The design of the system was designed based on the results of interviews with oyster mushroom farmers regarding the constraints faced, then proceed with the design and manufacture of hardware and software for an IoT-based oyster mushroom kumbung watering and heating system. The result of this research is that the system can respond to changes in temperature and humidity conditions in the kumbung room by automatically watering and heating the kumbung room. To return to the setpoint temperature value (25oC-28oC), it is necessary to heat the kumbung room with an average duration of heating of 383 seconds, and to return to the setpoint humidity value (75%-90%), it is necessary to water the kumbung room with an average watering time of 115 seconds.

Abstract

Based on the value of feedback obtained from the sensor (LDR), the PID algorithm uses the error value obtained from the comparison between the sensor value and the setpoint value to perform calculations so that the PWM generator will use the output value to produce a row of pulses that will be converted to a voltage (signal) with a range of  0 to 255 (0 volt to 5 volt)  and is used to turn on the LED lamp according to the desired light level. The output characteristics generated by the PID control for each coefficient can be used as a benchmark to determine the correct coefficient value for Propotional coefficient, Integral coefficient and Derivative coefficient  as a whole. From the test results, it can be seen that the coefficient value adjustment can be taken based on the size of the difference or error contained in the system. If the difference in error is slight, the use of large coefficient values, especially in derivative coefficients. It helps the system achieve a stable condition and reduces overshoot. Still, if the error value is significant, then applying a considerable efficiency value will make the system achieve stable condition stable becomes a little tricky because it is possible to overshoot the PID output.

Abstract

The role of the early warning system by the KP2C Community in providing information on flood disasters that often occur in the Cileungsi – Cikeas watershed really helps the community in reducing the impact of the unavoidable flood disaster. The creation of the game “Cikeas – Cileungsi Overflow” aims to introduce knowledge about actions related to flood early warning to the wider community more effectively and fun. By using the gamification method, real activities carried out by KP2C such as interacting with residents through social media, monitoring the condition of upstream rivers, and providing disaster warnings, can be displayed in a simpler form into an educational game. The process of creating a game is carried out by conducting research on various types of KP2C activities in becoming an early warning instrument and then converting the data into a game mechanic. Through the results of game testing, 93.4% of respondents said the gameplay displayed in the game "Cikeas – Cileungsi Overflow'' was quite interesting and 90% of respondents stated that their understanding of the concept of a flood early warning system had been conveyed well. There are still several aspects that need to be developed in the future from the "Cikeas Cileungsi Overflow '' game, especially the leaderboard mechanism which still has problems and continued development to the Android platform
