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. The converted serial number/code has been successfully saved to the SD card in the form of a text document format ABSTRAK: Daftar hadir merupakan bagian penting untuk mengelola tenaga kerja pendidik dalam sekolah.

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.

Abstract

Microhydro power plant is an alternative for producing small-scale electrical energy uses hydropower. Microhydro has three main components, water, turbine and generator. In the environment , it can also be used as a microhydro power plant on a home scale. The components needed to make microhydro prototype are water reservoirs, valves, MOV,generators, flowmeters, voltage sensors,LED . The water reservoir is installed as high as 4 meters. MOV is used as an actuator to control the flow of water to adjust the degree of valve opening automatically. Generator is connected to convert mechanical energy into electrical energy, flowmeter to determine the debit value and a voltage sensor is connected. The system will be connected to the load of an LED light. When the lamp load changes, it is expected that the voltage generated by the generator remains stable. To regulate the voltage to remain stable, voltage control is carried out by adjusting the degree of valve opening using a PID control system. Voltage control with PID control based on Ziegler Nichols theory with oscillation method. Through experimentation, it was obtained that the KP = 0.9, Ki = 0.45 and Kd = 0.45 constants were the most optimal because the response of the oscillating system was 1.15 seconds shorter. The time required for the voltage to stabilize to the setpoint from the start of the system being turned on is 46.20 seconds. The greater the degree of valve opening, the greater the voltage generated, because the debit produced is greater.

Abstract

In nurseries, storage temperature plays a very important role in the quality of cayenne pepper seeds, room temperature affects seed viability, room temperature and humidity can be maintained by adjusting humidity 70-80% at room temperature 20-25ºC. (Fitrianti, 2020). And the condition of the soil that lacks or excess water also affects the lack of nutrients that will be obtained by plants during the rainy season. then a tool was designed entitled "Design of a Plastic Roof Opener / Cover With Soil Temperature and Humidity Control in Chili Seedlings Using IoT". The work system starts from a time checking system set by the user, then a soil moisture sensor that detects the level of soil moisture to be detected and a DHT11 sensor to detect air temperature and humidity, then the results of the data obtained from the sensor will be monitored through the website, with the help of the ESP32 Board so that the data obtained can be displayed to the monitor and also to the LCD. This tool can also be monitored on the Internet of Things to make it easier for users. The open and close control system for chili seedlings uses Servo with Node MCU ESP32 control so that when it rains the roof closes automatically using the Raindrop sensor. and there at the same time can monitor soil moisture and temperature that is transmitted to the LCD. The reading of the results from the Soil Moisture Sensor was obtained with a lower limit value of 43.5% and an upper limit of 79.4%, and also the results of the comparison between DHT11 and HTC-1 were 7.82% temperature and 11.33% humidity ABSTRAK: Didalam pembibitan,Suhu penyimpan berperan sangat penting terhadap kualitas bibit cabai rawit, suhu ruang mempengaruhi viabilitas benih ,suhu dan kelembaban ruangan dapat di pertahankan dengan mengatur kelembaban 70-80% suhu ruang 20-25ºC. (Fitrianti, 2020).Dan keadaan tanah yang kurang air atau berlebih juga berpengaruh pada tidak maksimalnya nutrisi yang akan di peroleh pada tanaman saat musim hujan. maka dirancangkan sebuah alat yang berjudul “Rancang Bangun Pembuka / Penutup Atap Plastik Dengan Pengatur Suhu Dan Kelembaban Tanah Pada Pembibitan Cabai Menngunakan IoT”. Sistem kerja dimulai dari sistem pengecekan waktu yang di atur oleh pengguna, lalu sensor kelembaban tanah yang mendeteksi tingkat kelembaban tanah yang akan di deteksi dan sensor DHT11 untuk mendeteksi suhu dan kelembaban udara, kemudian hasil dari data yang diperoleh dari sensor akan dimonitoring melalui website, dengan bantuan Board ESP32 agar data yang di peroleh dapat di tampilkan ke monitor dan juga ke LCD. Alat ini juga dapat dimonitoring secara Internet of Things untuk mempermudah pengguna. Sistem kendali buka tutup pada bibit cabai menggunakan Servo dengan pengendalian Node MCU ESP32 .agar ketika waktu hujan atap menutup otomatis dengan menggunakan sensor Raindrop. dan disitu juga sekaligus bisa memonitoring kelembaban tanah dan suhu yang di transmisikan ke LCD. Pembacaan hasil dari Sensor Soil Moisture didapatkan dengan nilai batas bawah 43,5% dan batas atas 79,4%, serta juga Hasil dari perbandingan antara DHT11 dan HTC-1 ialah suhu 7,82% dan kelembaban 11,33%
