Abstract

Horticultural commodities are agriculture that has a lot of demand in the market. Based on this, a planting system with the aeroponic method was made with an IoT-based monitoring and control system so that its growth is maintained. A system with complex planning is needed to simplify human life. Then a remote monitoring and control system was designed with IoT technology in the aeroponic method. The way this tool works is to send sensor data from the Node MCU via the internet to the cloud and the data is stored in real-time in the Firebase, the data is sent to the Android platform so that the data can be read by the user and the data is sent to a Google spreadsheet automatically which will later be analyzed. Will update data every 15 minutes. In this study, calibration of the DHT11 sensor with HTC Digital obtained an accuracy of 95.5% humidity and 97% temperature, the LDR sensor with LUX meter obtained an accuracy rate of 75.163%, pH sensor with pH meter 97.33%, ultrasonic sensor and ruler. get 100% accuracy, the bandwidth used is 20 Mbps. The network quality test is delayed, with 3 different test times, busy hours (19.00 - 23.00 WIB), empty hours (01.00 - 03.00 WIB), normal hours (12.00 - 14.00 WIB). From network testing, the minimum delay is 0.255 seconds, and the maximum is 0.291 seconds. The results of testing tools during seeding, lettuce plants can grow well.

Abstract

Abstract - In the current millennial era, electrical energy remains a fundamental need to sustain human activities. But on the other hand, electrical energy can also be dangerous if it is not equipped with a protection system in its application. The protection system is one of the systems in the electric power system that aims to anticipate as well as secure the possibility of disturbances occurring in the electric power system.This research is a design of an overcurrent protection monitoring system using a current transformer (PZEM-004T sensor) based on a microcontroller and the Internet of Things. This system consists of an Arduino AT-Mega 328 microcontroller, a PZEM-004T sensor, a relay module, a NodeMCU ESP8266 WiFi module, mySql as a database server and Google web browser software as an application to access monitoring websites for protection systems on the internet. The research method used is the quantitative research method and experimental metthod. Tests carried out by measuring the PZEM-004T sensor, testing system reliability and monitoring system performance on the website. Where are the results from testing the PZEM-004T sensor and the data displayed on the website has an error percentage of approximately 6.4%. In testing the protection system with 3 different current protection set point values, the average circuit breaking time was 171.6 milliseconds.

Abstract

Electrical energy is a very complex problem for every country in the world, as well as in Indonesia in particular, with the rapid progress of the country’s industry, of course, followed by an increase in the generation of electrical energy. While the current energy generation most often comes from fossil fuels, which are increasingly depleting, the energy supply will decrease and increase sales. Therefore, every country is competing to find other energy for electrical energy generation. Renewable energy is a green energy generator whose supply is abundant and inexhaustible. Solar power plants (PLTS) are one of the green energies developed by the Indonesian government to utilize energy derived from non-fossil fuels. To support this, it is necessary to study and research to be done using the DC-DC up/down converter is expected to obtain results that can be used as a reference in the development of solar power plants (PLTS). With a DC-DC up/down converter, the voltage stabilization produced by PLTS can be stabilized by a DC-DC converter from 9 volts DC to 11.5 volts for a minimum voltage. Above 12 volts to 18 volts, up to 12 volts can be stabilized.

Abstract

Tukang yang ada di Desa Keliki belum memiliki skil dan pengetahuan dasar ketekniksipilan khususnya yang berkaitan dengan pekerjaan pemasangan kap baja ringan.Belum ada wadah khusus profesi tukang bangunan.Tukang belum memiliki pengetahuan dasar pertukangan khususnya dalam bidang pemasangan kap baja ringan.Tukang bangunan yang ada di Desa Keliki belum pernah mendapatkan pelatihan pertukangan seperti pekerjaan kapa baja ringan. Pelatihan pertukangan ini bermaksud untuk memberikan pelatihan pekerjaan pemasangan kap baja ringan. Dengan demikian tukangtukang yang terlibat nantinya akan menghasilkan bangunan yang lebih layak teknis, lebih aman, lebih murah dan lebih ramah lingkungan Tujuan dari kegiatan pengabdian ini adalah untuk memberikan pelatihan pekerjaan pemasangan kap baja ringan kepada tukang-tukang yang ada di Desa Keliki. Setelah kegiatan pengabdian ini, proyek-proyek pembangunan khususnya fasilitas pariwisata yang ada di Desa Keliki.Metode yang digunakan dalam kegiatan ini, melalui surve dan wawancara terhadap kepaladesa dan ketua Bumdes. Metode pelatihan, dengan cara pemberikan pembekalan yang diberikan oleh dosen di jurusan Teknik Sipil Politeknik Negeri Bali. Dengan dilaksanakannya kegiatan pelatihan pemasangan rangka atap baja ringan ini, peserta pelatihan dapat mengetahui dasar - dasar konstruksi rangka atap dan dapat mempraktekkannya. Pada kegiatan Pelatihan ini para tukang diajarkan dan dilatih untuk membuat dan menyambung rangka atap dengan bahan baja ringan. Hasil dari kegiatan pengabdian ini berupa bangunan yang menggunakan kap baja ringan

Abstract

Create an Internet of Things-based Air Conditioner operating system to make it easier to operate the AC. This research examines whether the system designed can transmit IR Code via IR Transmitter to AC if the device is placed at different distances. The steps to make it happen are to follow the stages of the prototyping method, which consist of gathering requirements, developing prototypes, and testing prototypes. The hardware circuit built consists of the Node MCU ESP8266, DHT 11 sensor, Infra-Red, software consisting of Arduino IDE, and blynk. By placing the NodeMCU ESP 8266 in positions with different distances, the tool can send IR Code data via the IR Transmitter to the AC, buttons on the blynk application have been made and can work according to their functions. The test was carried out with 4 different location positions, namely position 1 with a distance of 1 meter, position 2 with a distance of 3 meters, position 3 with a distance of 2 meters, and position 4 with a distance of 4 meters. From 4 test location positions with sufficient category signals to very good categories, microcontrollers can be connected to the blynk application on smartphone users. The Blynk application can function according to the commands made, the IR code can be sent through the IR transmitter to the air conditioner (AC). The DHT 11 sensor successfully measures the temperature and humidity of the air. Hopefully, in the future, the development of this tool into a multi-controller capable control not only AC but also other electronic devices.
