Abstract

Sheep are one of the livestock that are cultivated to be used as materials for food and textiles. Therefore, sheep health care on sheep farms really needs to be considered to ensure that all sheep are maintained in good health so that the productivity of the farm increases. Generally, sheep health can be monitored through body temperature and heart rate to determine whether the sheep is in normal condition or is in abnormal condition. To make it easier to monitor the health of sheep which is currently still done. manually and has to wait for people who have the ability to take temperature and sheep pulse measurements can cause some farmers to not realize that there are sheep who have health problems, this study aims to design and implement a tool that can monitor sheep health using a temperature sensor module and a pulse sensor which is then connected to NodeMCU ESP8266 which functions as a microcontroller that will process and then send the data to the server to be displayed to users through a web application. This research successfully monitored sheep health based on body temperature and heart rate with a temperature sensor error rate of 0.2% and a pulse sensor error of 3.2%. The results of this monitoring can be a reference for farmers to provide appropriate treatment to their livestock so that the health of their sheep is always in good condition.

Abstract

Manual seeding process by inserting one vegetable seed into the rockwool media is a repetitive activity and requires a long time. Automatic seeder mechatronic system for pick and place process of hydroponics vegetable seeds on rockwool media will help hydroponic vegetable cultivators which require routine seeding process. The automatic seeder controller that has been made by author functions to control the seeder mechanism, rockwool perforation mechanism, and tray movement mechanism that has been made before to do the pick and place process of hydroponic vegetable seeds on rockwool media. The whole seeder and rockwool perforation process are done on a belt conveyor moving in the step of row distance of the rockwool tray. The difficulties faced are taking the small seed, the seed shape is not round, and the precision of inserting the seed into the hole in rockwool. Automatic seeder use STM32 Mapple Mini microcontroller as the controller, IR proximity sensor to detect tray position on conveyor, and magnetic hall sensor to detect the position of rockwool perforation and seeder mechanism. Based on observation data from 6 trials, the hole in the rockwool was filled with exactly 1 seed with an average percentage of 95,7 % for the pak choi seeds with a round shape and 83 % for the lettuce seeds with a flat shape. Round seeds shape has the highest percentage because when sucked, the seed can cover the entire needle hole.

Abstract

From time to time, electricity consumption continues to increase rapidly. The current average growth in electricity consumption is 2.3-2.5%, and by the end of 2030, it is estimated that the need for electrical energy will be twice the current one, which is around 16,000 TWh per year. Small things that have often been done so far, maybe without us realizing it has had a big impact and if it continues to be done it will result in a scarcity of electrical energy. This can happen because of a consumptive lifestyle that is wasteful and inefficient. This consumptive behavior towards electrical energy can change patterns and lifestyles to become more wasteful. The problem of wasting electrical energy is 80% caused by humans and 20% is caused by technical factors, this is due to excessive and untimely use of electricity. One solution to this problem can be overcome by using Internet of Things technology. In this project, an automatic lamp design is made using a PIR sensor, LDR sensor, and DHT11 temperature monitoring with nodeMCU and Blynk, to increase the efficiency of electricity use at home. Automatic light is a system that can control lights automatically according to needs. The PIR and LDR sensors will detect the presence of movement and darkness in the room, so the lights will only turn on when needed. In addition, this system also has a temperature monitoring feature that can monitor room temperature in real time which can be accessed by the Blynk application. With this system, users can save more electricity and avoid fires due to lights that are constantly on. This article produces a prototype of an automatic light control device and room temperature monitoring and an application design that can already be installed on Android. Based on testing of the PIR and LDR sensors, the sensor can work at a distance of 5 meters down and the tool functions properly. The DHT11 sensor can also function and read the temperature in the room and display the value in the application ABSTRAK: Penggunaan daya terus meningkat dengan cepat dari waktu ke waktu. Pada akhir tahun 2030, diperkirakan kebutuhan energi listrik akan meningkat dua kali lipat dari saat ini, atau sekitar 16.000 TWh per tahun, dengan rata-rata peningkatan tahunan sebesar 2,3-2,5%. Tindakan kecil yang sering dilakukan di masa lalu, mungkin tanpa kita sadari, telah memberikan dampak yang signifikan, dan jika terus berlanjut akan menyebabkan kekurangan energi listrik. Gaya hidup konsumtif yang boros dan tidak efektif dapat menyebabkan hal ini. Penggunaan energi listrik yang tidak efisien ini dapat mengubah perilaku dan kehidupan serta menjadikannya boros. Karena penggunaan daya yang berlebihan dan tidak teratur, orang bertanggung jawab atas 80% masalah pemborosan energi dan elemen teknologi 20% darinya. Salah satu solusi dari permasalahan tersebut dapat diatasi dengan menggunakan teknologi Internet of Things. Pada proyek ini dibuat rancang bangun lampu otomatis memanfaatkan sensor PIR, sensor LDR, dan monitoring suhu DHT11 dengan nodeMCU dan Blynk, untuk meningkatkan efisiensi penggunaan listrik di rumah. Lampu otomatis merupakan sistem yang dapat mengontrol lampu secara otomatis sesuai dengan kebutuhan. Sensor PIR dan LDR akan mendeteksi keberadaan gerakan dan kegelapan di ruangan, sehingga lampu hanya akan menyala jika diperlukan saja. Selain itu, sistem ini juga memiliki fitur monitoring suhu yang dapat memantau suhu ruangan secara realtime yang bisa di akses diaplikasi Blynk. Dengan sistem ini, pengguna dapat lebih hemat listrik dan terhindar dari kebakaran akibat lampu yang terus menyala. Pada artikel ini menghasilkan sebuah prototipe alat pengendali lampu otomatis dan monitoring suhu ruangan dan desain aplikasi yang sudah bisa dipasang di android. Berdasarkan pengujian sensor PIR dan LDR, sensor dapat bekerja pada jarak 5 meter ke bawah dan alat berfungsi dengan baik. Sensor DHT11 pun dapat berfungsi dan membaca suhu diruangan serta menampilkan nilainya pada aplikasinya
