Abstract

Ruang rawat inap merupakan aspek penting bagi kesembuhan pasien yang dirawat di rumah sakit. Rasa nyaman saat menjalani perawatan mampu mempercepat proses kesembuhan pasien. Suhu udara, kelembaban udara, serta udara sejuk saat pagi dan sore hari merupakan faktor kenyamanan pada ruang rawat inap. Berdasar Keputusan Menteri Kesehatan Nomor 7 Tahun 2016 menetapkan standar mutu udara ruang rawat inap dengan suhu ruang 22-24°C dengan kelembaban 45-60%. Pada penelitian dibuat suatu sistem kontrol menggunakan mikrokontroller Arduino Mega 2560 . Sensor DHT22 digunakan untuk membaca nilai suhu dan kelembaban didalam ruang rawat inap sehingga mampu mengontrol proses pendinginan ruang dan sirkulasi udara secara otomatis. Dengan dukungan modul ESP8266 pengaturan ruangan dapat dikontrol secara manual melalui smartphone yang sudah disediakan. Jendela pada ruangan juga dapat terbuka secara otomatis sesuai waktu yang diatur dengan modul Real Time Clock (RTC) DS3231 dan dapat pula di kontrol secara manual dari smartphone dengan motor servo yang terhubung dengan sistem. Sistem dilengkapi juga dengan sensor BH1750FVI sebagai sensor intensitas cahaya untuk mengatur intensitas cahaya pada ruangan. Hasil pembacaan suhu, kelembaban serta intensitas cahaya dapat dilihat pada tampilan smartphone menggunakan aplikasi MIT APP Inventor dan juga Liquid Crystal Display pada sistem.

Abstract

Pears in early autumn can be harvested with the best quality. Pear farmers sort the fruit so that it can be consumed and sold with the best quality. Therefore automatic detection and sorting tools can make it easier for farmers to sort pears. This tool can sort fresh and rotten fruit using the TCS-3200 sensor based on the ESP32 microcontroller. The harvested fruit is collected in a container and the fruit will go out onto the conveyor. The conveyor has a length of 60 cm using a Nema 17 stepper motor that moves automatically, the TCS-3200 sensor is placed in the middle of the conveyor so that it can detect moving pears. The results of the sorting door servo if the fruit is declared fresh then the servo remains closed straight so that the fruit will go to the front container, and vice versa the fruit is declared rotten then the servo will open up so that the fruit will go down. At the end of the conveyor there is an IR sensor which is used to send a signal to the servo motor of the main container door, so that if the fruit has been detected and leads to the IR sensor, the main container door will open and take out new pears. And for data collection the number of pears can be seen through the LCD by calculating the number of pears that have been detected, the number of fresh fruit and the number of rotten fruit, and the overall calculation of the amount of data can be seen through a spreadsheet. In this case, it is hoped that this research can help and facilitate farmers in harvesting fruit on a large scale while being efficient in time and energy.

Abstract

Measuring the engine's temperature and compression pressure in cars is a crucial part of engine maintenance and performance evaluation. The objective of this study is to develop an accurate and efficient spreadsheet-based measurement system for determining engine temperature and compression pressure in automobiles. For this investigation, data from car engines was collected using engine temperature thermometers and compression pressure gauges. The collected data is then fed into a spreadsheet designed specifically to assess and automatically calculate engine temperature and compression pressure. The results show how reliable and accurate the measurements made using this spreadsheet-based measurement technique are. This approach's main benefits are also its flexibility and ease of use, since users can rapidly adapt the spreadsheet to the particular needs of the engine being tested. With this technology in place, car owners or professionals who do engine maintenance can quickly detect potential engine problems, such as valve leakage or unexpected temperature increases. Therefore, to increase fuel efficiency and extend engine life, spreadsheets can be utilized as a tool for measuring engine performance. The goal of this project is to facilitate the work of auto repair shop owners by utilizing the Esp8266 microcontroller for the DS18b20 sensor and compression sensor. Even so, there are several difficulties, like a sluggish internet connection that delays uploading data to the LCD and spreadsheets that are less useful because of a bad internet connection.
