Abstract

Pembangkit listrik tenaga mikrohidro adalah salah satu sumber energi listrik terbarukan saat ini dengan memanfaatkan tenaga air berskala kecil untuk penggeraknya. PLTMH pada umumnya memiliki ruang kontrol yang berada jauh dengan sistemnya, sehingga dibutuhkan suatu sistem monitoring. Penggunaan sistem monitoring berbasis nirkabel menjadi salah satu solusi untuk mengatasi masalah tersebut dengan proses pengiriman informasi yang cepat dan mudah. Penelitian ini merancang suatu model routing data dengan perancangan hardware dan software pada komunikasi data. Sistem dibangun menggunakan mikrokontroller arduino dan komunikasi frekuensi Xbee dengan protocol zigbee. Pengujian dilakukan dengan menggunakan berbagai macam topologi yaitu topologi pair, star, mesh, tree, dan x dalam model routing data baik dalam lingkungan indoor maupun lingkungan outdoor. Hasil yang didapat berdasarkan pengujian pada lingkungan indoor menunjukan Xbee tetap dapat mengirim dalam ruangan yang memiliki penghalang dengan jarak 21m, sedangkan pada pengujian outdoor, Xbee dapat tetap mengirim dengan jarak maksimum 120.5m menggunakan model topologi x. Berdasarkan semua pemodelan yang telah dilakukan, topologi x merupakan model yang dianggap paling berhasil walaupun memiliki kelemahan dalam tingkat kerapihan penerimaan data namun dari tingkat keamanannya ketika terjadi masalah dengan salah satu node, topologi x masih memiliki jalur lain untuk dapat mengirimkan data ke penerima. Micro hydropower plant is one of the current renewable electrical energy by making use of small-scale water power for propulsion. MHPP generally has a control room that was away with the system, so we need a monitoring system. The use of wireless-based monitoring systems into one solution to overcome these problems with the delivery process information quickly and easily. Therefore, we designed a model of routing data by designing hardware and software in data communication comprising Arduino microcontroller and Xbee frequency communication with ZigBee protocol. Testing is done by using a variety of topologies, namely topology pair, star, mesh, tree, and x in the model routing of data in both the indoor and outdoor environment. The results obtained by testing the indoor environment is Xbee can still send in a room that had a barrier at a distance of 21m, while the outdoor testing Xbee can still send more than the maximum distance delivery Xbee 70.5m in research that is by using the model topology x. Based on all the modeling that has been done, topology x is the model that is considered the most successful even though it has weaknesses in the level of data reception tidiness. But the level of security has the advantage that when there is a problem with one of the nodes, the x topology still has another path to be able to send data to the receiver.

Abstract

Pesatnya perkembangan teknologi monitoring saat ini membantu manusia mempermudah melakukan pekerjaan. Sebagai contoh, monitoring PLTMH dapat digunakan untuk memperoleh data untuk memprediksikan kebutuhan energi listrik. Data yang akan digunakan dihasilkan dari proses pengambilan, pengiriman, penerimaan sampai data dapat ditampilkan dan disimpan dalam piranti penyimpan. Sistem monitoring PLTMH ini berbasis JSN, membutuhkan modul komunikasi serta data logger. Penempatan logger data diperlukan model yang paling sesuai untuk memenuhi spesifikasi data yang diinginkan dan dapat disimpan dalam piranti penyimpanan dalam format “.txt”. Pada penelitian ini digunakan 2 model. Model 1 menempatkan logger data pada rangkaian pengirim dan Model 2 pada rangkaian penerima, sehingga parameter keberhasilan terlihat pada spesifikasi kesamaan data yang dihimpun berdasarkan waktu dan disimpan dalam piranti penyimpanan serta ditampilkan pada serial monitor. Hasil pengujian sampel akuisisi data yang diambil menunjukkan kecepatan putar sebesar 4693 rpm dan frekuensi 156 Hz. Data ini ditampilkan pada serial monitor dan piranti penyimpanan menunjukkan data yang sama. Uji Model 1 tidak menghasilkan data yang bersesuaian dengan pembacaan sensor, sedangkan uji Model 2 yang menempatkan logger data pada rangkaian pengirim dihasikan data yang bersesuain berdasarkan setting waktu pada RTC untuk waktu nyata, serta kesesuaian dari pembacaan sensor pada SD Card maupun serial monitor. Sehingga perancangan Model 2 lebih sesuai untuk penerapan sistem monitoring akuisi data PLTMH berbasis JSN yang informasi datanya dapat digunakan dalam keperluan peramalan energi pada masa mendatang. The rapid development of monitoring technology is currently helping humans make it easier to do work. For example, monitoring of PLTMH can be used to obtain data to predict electricity demand. The data to be used is generated from taking, sending, and receiving until the data can be displayed and stored in a storage device. This MHP monitoring system is based on JSN, requiring communication modules and data loggers. Placement of the data logger requires the most appropriate model to meet the desired data specifications. It can be stored in a storage device in “.txt” format. This study used two models. Model 1 places a data logger on the sending circuit and Model 2 on the receiving circuit so that the parameters of success are visible in the data similarity specifications collected by time, stored in a storage device, and displayed on a serial monitor. The test results for the data acquisition samples showed a rotational speed of 4693 rpm and a frequency of 156 Hz. This data is displayed on the serial monitor, and the storage device shows the same data. The Model 1 test did not produce data that corresponded to sensor readings, while the Model 2 test, which placed a data logger on the sending circuit, generated data that corresponded to the time setting on the RTC for real-time, as well as the suitability of the sensor readings on the SD Card and serial monitor. So the design of Model 2 is more suitable for implementing a JSN-based MHP data acquisition monitoring system whose data information can be used for future energy forecasting purposes.

Abstract

This study designed an axial mode helix antenna with a working frequency used of 2.1 GHz, which has a return loss value of < -10 dB and VSWR < 1.3. The simulation was carried out using the CST studio suite 2020 software by designing a helix antenna from the calculation results to optimization of the helix antenna structure, namely the distance between the windings, the number of windings, the diameter of the windings, and the diameter of the ground plane until the simulation results are in accordance with the specifications of the desired parameters. Based on the final results of the return loss parameters and VSWR has met the designed specification standards, from the simulation results of the axial mode helix antenna, the results were obtained, namely at a return loss of -22 dB and at a VSWR value obtained 1.17. The results of the measurement of the axial mode helix antenna obtained the same result at a return loss of -22 dB and at VSWR 1.17 but the frequency value used in the measurement shifted to 2.45 GHz, this is not a problem because the s-band frequency can work from 2 GHz to 4 GHz.

Abstract

Crimes such as theft and housebreaking are serious problems related to security. This problem often occurs when the homeowner is out of town or leaving the house for a few days. Therefore, an effective security system is needed so that the house is not easily broken into and can be monitored via smartphone by the owner. To minimize the crime rate, we designed a microcontroller-based automatic door lock. This automatic system can control the solenoid door lock and function as a home security. This study aims to develop a door lock and window security system based on a microcontroller and the Internet of Things. This system utilizes RFID to open the door which is processed by Arduino, as well as a PIR Sensor for double security which is processed using NodeMCU ESP8266. The smartphone functions as a medium for monitoring and opening the door. The NodeMCU ESP8266 microcontroller on the PIR Sensor is tasked with processing data so that when the sensor detects movement, the buzzer will sound and send a notification to the smartphone. The results of the study show that the automatic door lock can be accessed via RFID and applications on smartphones. The system can detect RFID at a distance of 3 cm with a response time of 2-5 seconds, and successfully detects movement in humans and animals with an accuracy rate of 86.67%.

Abstract

Like humans, plants need water for growth and development. Where water plays an important role in the process of photosynthesis and transpiration as the main component in the photosynthesis process. Chili plants require several nutrients such as water and sunlight to produce the best quality chili. In an effort to improve the efficiency of watering chili plants, this research proposes an Internet of Things (IoT) based watering automation system using fuzzy logic. The system is designed to measure several environmental parameters such as soil moisture, air temperature, and relative humidity level, and use the data to make the right watering decision. This system will make it easier for chili farmers to take care of their plants without having to pay attention to the plants all the time. In this research, the system is designed using fuzzy logic using an ESP8266 microcontroller so that the system can be integrated with the web. The fuzzy logic system will produce an output in the form of a watering requirement level that is in accordance with the current environmental conditions based on data from existing sensors. These results will be used to control the watering actuator in the form of a water pump. All existing data will be integrated with the web to find out the condition of chili plants. After testing and analyzing the tool that has been made, the tool functions properly in accordance with the design. The tool will only water when conditions require watering. Then for all data taken will be integrated with the existing web. The analysis shows that testing the ambient air temperature with 10 different experiments has an average error of 1.41%, while testing the ambient humidity has an average error of 0.14%. And for testing the height of the water storage area has an average error of 5.43%.Keywords— ESP8266, Internet of Things (IoT), Fuzzy Logic, Chili Plants.
