Abstract

To improve the quality of the bionic hands used by some disabled people, new innovations are needed. By implementing IoT in the development of bionic hands, it can make it easier for patients to obtain information, such as monitoring battery capacity, bionic hand life, and bionic hand health. So we need a component that is able to transmit this information. In this paper, we are the Meander Planar Inverted F Antenna (PIFA) at a frequency of 915 – 925 MHz which is compatible with Sigfox or LoRa IoT technology. The antenna is designed to have miniature characteristics so that it does not interfere with other components when implanted in the bionic arm and is curved so that it can follow the curved shape of the bionic arm. The miniature technique used is the winding technique and the conformal technique is used to give a curved effect to the antenna. The design is carried out very systematically by streamlining the steps using the Design of Experiment method. It is proven that it only takes 6 steps to get results that match the specifications. The simulation results show the value of S11 is -21 dB, resonant frequency is 924.9 MHz, bandwidth is 13.5 MHz, gain is -23.34 dBi and radiation pattern is omnidirectional.

Abstract

Paragliding is a type of free-flying sport using cloth wings, commonly called a parachute. At the time of takeoff, this sport utilizes the thrust generated by the wind and lands using the feet. Based on the available data, there are still many tourists and amateur paragliding users who have difficulty finding weather information in the takeoff and landing areas. Weather is an important factor in this sport to minimize accidents and avoid flight failures due to not being able to control a parachute hit by strong winds. Therefore, based on the existing problems, a system is needed that can provide weather condition data for takeoff and landing safety with wind speed parameters using an anemometer sensor, for temperature and humidity using a DHT-22 sensor, and a wind direction sensor using a Wind Vane Direction sensor. The data processed by the Arduino Mega2560 will be displayed on a 20×4 LCD (Liquid Crystal Display). The results of the process are also sent through a data transmission system using LoRa (Long Range) technology. From the results of the tests carried out, it shows that the functionality of all sensors is running as it should. The average calibration error of the DHT sensor data is 22 for temperature, 2,14 % and humidity, 1,37% and the wind speed sensor is 2,85 %. In addition, the LoRa communication test between the node and the gateway shows good results with the average RSSI (Received Signal Strength Indicator) value at node 1 being -77 dBm and node 2 being -34 dBm ABSTRAK: Paralayang merupakan salah satu jenis olahraga terbang bebas dengan menggunakan sayap kain atau biasa disebut dengan parasut. Pada saat lepas landas olahraga ini memanfaatkan gaya dorong yang dihasilkan oleh angin dan mendarat menggunakan kaki. Berdasarkan data yang ada masih banyak wisatawan maupun pengguna paralayang amatir yang mengalami kesulitan untuk mengetahui informasi cuaca pada area lepas landas dan pendaratan. Cuaca menjadi faktor penting dalam olahraga ini untuk meminimalisir terjadinya kecelakaan dan menghindari terjadinya gagal terbang akibat tidak bisa mengendalikan parasut yang diterpa angin kencang. Maka dari itu, berdasarkan permasalahan yang ada diperlukan suatu sistem yang dapat memberikan data kondisi cuaca untuk keselamatan lepas landas  dan mendarat dengan parameter kecepatan angin yang menggunakan sensor Anemometer, untuk suhu dan kelembaban menggunakan sensor DHT 22, dan sensor arah angin menggunakan sensor Wind Vane Direction dan data yang diproses oleh Arduino Mega2560 ditampilkan pada LCD (Liquid Crystal Display) 20×4, hasil dari proses tersebut juga dikirim melalui sistem transmisi data dengan menggunakan teknologi LoRa (Long Range). Dari hasil pengujian yang dilakukan menunjukkan bahwa fungsionalitas semua sensor sudah berjalan sebagaimana mestinya, rata-rata kesalahan kalibrasi data sensor DHT 22 untuk suhu 2,14% dan kelembaban 1,37%, dan sensor kecepatan angin sebesar 2,85%. Selain itu pengujian komunikasi LoRa antara node dan gateway menunjukan hasil yang baik dengan nilai RSSI (Received Signal Strength Indicator) rata-rata pada node 1 adalah -77 dBm dan node 2 adalah -34 dBm.

Abstract

To support production activities, Perum Peruri requires a stable electricity supply. A tap changer is used to keep the output voltage on the secondary side of the transformer constant with a value of 20 kV, which is installed on a 150 kV power transformer. The purpose of this study was to reduce tap movement on OLTC to stabilize the secondary voltage of the 150 kV power transformer at the Perum Peruri substation. The data collection method used is a literature study to obtain a theoretical basis, as well as using field studies with observation techniques to collect data in the form of secondary voltage (Vs), primary voltage (Vp), current, power, tap position, and power transformer specifications at the Perum Peruri Substation. 30 experiments were conducted using the Tiuan Neural Network (JST) to obtain the largest regression value or close to 1 and to obtain the smallest MSE (Mean Squad Error) value. The magnitude of the regression value and the MSE value will affect the correlation between the simulation results on Simulink and the target tap determined based on the transformer nameplate. ABSTRAK: Untuk menunjang kegiatan produksi, Perum Peruri membutuhkan pasokan listrik yang stabil. Digunakan tap changer untuk menjaga tegangan output pada sisi sekunder transformator agar tetap konstan dengan nilai 20 kV, yang dipasang pada transformator daya 150 kV. Tujuan penelitian ini adalah untuk mengurangi pergerakan tap pada OLTC untuk menstabilkan tegangan sekunder transformator daya 150 kV di gardu induk Perum Peruri. Metode pengumpulan data yang digunakan adalah studi pustaka untuk mendapatkan landasan teori, serta menggunakan studi lapangan dengan teknik observasi untuk mengumpulkan data berupa tegangan sekunder (Vs), tegangan primer (Vp), arus, daya, posisi tap, dan spesifikasi transformator daya pada Gardu Induk Perum Peruri. Dilakukan 30 kali percobaan menggunakan Jaringan Syaraf Tiuan (JST) untuk mendapatkan nilai regression terbesar atau mendekati 1 dan untuk mendapatkan nilai MSE (Mean Squad Error) terkecil. Besarnya nilai regression dan nilai MSE akan mempengaruhi korelasi antara hasil simulasi pada Simulink dengan tap target yang ditentukan berdasarkan nameplate transformator.

Abstract

Attendance lists are an important part of managing the teaching workforce in schools. However, at SDN Kalirejo 1, they still use the manual attendance list. The purpose of this study is to design an attendance system using an excel-based RFID that is reliable and can be used by agencies within a certain period of time. The method in this research has several stages, namely planning, designing, coding and testing. The results of the research that the SDN Kalirejo I agencies 80% agree, with the presence of an Excel-based Arduino RFID presence system. The use of this system will be easier because the recording process is done automatically, and the use of this system will minimize time because the attendance input process is done by scanning. The implementation limitations of making this attendance list system include the RTC must remain on, the RFID tag in the form of a card, the system users are all employees of SDN Kalirejo I and only one admin. In designing an application, limitations are needed so that the application that is designed does not go out of the initial plan of application design. There are two types of system requirements, namely functional requirements and non-functional requirements. This research resulted in testing the text document software successfully appearing in the excel application. In hardware testing, the Serial Number/Code on the RFID tag is read by the RFID reader. Serial Number/Code that is read on the RFID Reader can be converted into text format.

Abstract

Pondokkelor Village is one of the many areas in Probolinggo Regency which is a producer of shallots, in the nursery process the farmers buy seeds outside the area and do not produce them because of frequent failures in the growth process. Seeds that have been purchased will be stored in a dry room or warehouse and not damp within 1 to 2 months. In the process of storing shallot seeds, it will experience shrinkage so that it can affect the planting process, with this study which aims to compare the weight of shallot seeds stored for 30 days using conventional methods and storage box boxes that have been equipped with an IoT-based control system (Internet of things). This storage box is equipped with a DHT22 Sensor which functions to read the temperature in the storage room box and a Loadcell Sensor that functions to read the weight of the value on the seeds, as well as the Blynk Application which functions to monitor the shrinkage value of onion seedlings every day. If the reading of the temperature value on the DHT22 sensor is less than 26 degrees Celsius, the light bulb will turn on automatically and if the temperature value is more than 32 degrees Celsius, the fan will turn on. Sampling was done by placing shallot seeds on loadcell scales in a box and loadcell scales in an open room as much as 501 grams. From the results of research for 30 days, conventional storage methods have a difference in the average value of depreciation of 8.93 per day with IoT-based storage boxes and 11 grams of seed weight difference, so it can be concluded that the use of IoT-based storage boxes is more effective than conventional use.

Abstract

Infusion is an intravenous fluid that serves to replace lost body fluids in patients. So, the infusion must always be available in order to help speed up the patient's recovery. so that there is no delay in changing the infusion, the officer must always periodically control the state of the patient's infusion. Currently, some hospitals still use manual methods to control infusions, where officers must come to the patient room to check the patient's infusion status. for that reason I created an IoT-based infusion monitoring tool that can help hospital staff monitor the volume of infusion remotely, and also when the infusion remains 5% (5 minutes before the infusion runs out) and 0% automatically a notification will be sent to the officer. And this tool can also monitor the condition of the patient's heart rate remotely with the condition that the Pulse Sensor must be attached to the patient's finger. In this study, NodeMCU V3 was used as the control center. While the input uses a Load Cell sensor and a Pulse Sensor. And the resulting output will be displayed on the telegram application. With this tool, it is hoped that this tool can be marketed and can assist hospital staff in monitoring the condition of the infusion remotely. So that there is no delay in changing the infusion and the hospital can provide the best service to patients. ABSTRAK: Infus merupakan cairan intravena yang berfungsi mengganti cairan tubuh yang hilang pada pasien. Sehingga, infus harus selalu tersedia agar dapat membantu mempercepat kesembuhan pasien. agar tidak ada keterlambatan dalam penggantian infus maka petugas harus selalu mengontrol secara berkala tentang keadaan infus pasien. saat ini di beberapa rumah sakit masih menggunakan cara manual dalam melakukan pengontrolan infus, dimana petugas harus datang ke ruang pasien untuk memeriksa keadaan infus pasien. dengan alasan itulah saya membuat alat monitoring infus berbasis IoT yang bisa membantu petugas di rumah sakit dalam memantau volume infus dari jarak jauh, dan juga ketika infus tersisa 5% ( 5 menit sebelum infus habis ) dan 0% secara otomatis akan ada notifikasi yang di kirimkan ke petugas. Dan alat ini juga bisa memantau kondisi detak jantung pasien dari jarak jauh dengan syarat Pulse Sensor harus di tempelkan ke jari pasien. Pada penelitian ini, digunakan NodeMCU V3 sebagai pusat kontrol. Sedangkan inputnya menggunakan sensor Load Cell dan Pulse Sensor. Dan output yang di hasilkan akan di tampilkan pada aplikasi  telegram. Dengan adanya alat ini diharapkan alat ini dapat dapat di pasarkan dan dapat membantu petugas di rumah sakit dalam memantau kondisi infus dari jarak jauh. Agar tidak terjadi keterlambatan dalam penggantian infus dan rumah sakit dapat memberikan pelayanan yang terbaik kepada pasien.
