Abstract

Just like humans, plants need water for their growth and development. Plants should not have a lack or excess of water, soil that lacks water makes plants develop slowly and in ornamental plants makes the plants look not fresh and wilted and vice versa, plants that have too much water also make the plants unhealthy and can even cause the plants to die. The aim of the research is to design and build an automatic plant watering device that can be controlled remotely via an Android smartphone application, to determine the response speed of the tool in executing commands given by the user via the Android application, to find out the benefits of solar panels in order to save electricity usage in watering. Ornamental Plants by determining tool needs from various literature and collecting data from internet references and books as well as data that is needed and analyzing the components needed to make tools. The results of the research produced points, namely success in designing an automatic plant watering device based on the Wemos D1 R1 Microcontroller with the Blynk Application on Android as a remote control, the results of the characterization of the type of sensor used, namely the Soil sensor. Senor Soil has an accuracy of 98.65% and a standard deviation of ±0.14 for air temperature measurements and an accuracy of 98.72% and a standard deviation of ±0.38 for air humidity readings, the updated data on the Blynk Application is in accordance with the data sent by the Wemos D1 R1 Microcontroller. There is a time difference of 1 second between the data transmission time by the Wemos D1 R1 Microcontroller and the data reception time by the Blynk Application. The automatic plant watering tool that has been designed has a response speed of 2 seconds, starting from the time the user gives the command via the Blynk Application on the Smartphone until the device start the watering process

Abstract

The library holds the meaning as a place where various information is disseminated, whether printed or recorded in various media such as books, magazines, computers, and others. The library is a public place that provides information that can be visited by anyone, both children and adults are allowed to visit the library. Not apart from library visitors consisting of children to adults, it is not uncommon for disorder to occur inside the library, one of which is noise that can disturb the tranquility inside the library. Unexpected or unwanted noise because it does not match the library context can cause discomfort and disturbance to library visitors. Therefore, based on the considerations above, researchers try to propose research entitled "Design of Noise Detection Device with Sound Sensor Mic in the Library Based on Arduino". The system used utilizes the Arduino UNO microcontroller equipped with DF Player and other supporting devices so that in practice this tool can provide warnings when noise reaches a certain level in order to maintain noise below the predetermined threshold. The result of this research is that this system can operate by detecting the noise level with the KY307 mic sensor then using the Arduino microcontroller to analyze and process sound data to produce information about the noise level. This data is then displayed on the LCD screen and connected to an audio tweeter to provide a warning if the noise level exceeds the threshold.

Abstract

Methane gas detector adalah seperangkat alat instrumentasi yang dapat mendeteksi gas methane di industri lingkungan kerja. Gas methane merupakan rumus kimia CH4, hidrokarbon yang mengandung satu atom karbon (C) dan empat atom hydrogen (H) satuan ukur gas methane adalah % LEL. Gas methane merupakan zat reaktif sehingga mudah meledak jika bereaksi dengan api. Apabila terjadi kebocoran di area kilang dan gas methane tidak terdeteksi akan menimbulkan masalah explosive atau ledakan dan bahaya bagi manusia akan timbul gejala seperti sesak napas karena efek kekurangan oxygen (asphyxia). Adapun beberapa sensor yang digunakan sebagai methane gas detector di maintenance area II yaitu sensor catalytic dan sensor infrared. Ada perbedaan dari Sensor catalytic dan sensor infrared dari segi respon time dan Segi keandalan alat. Respon time dari sensor infrared pada saat menangkap gas yang masuk ke sensor yaitu dengan jumlah nilai waktu rata-rata 1,075 detik. Nilai tersebut lebih cepat dibandingkan dengan sensor catalytic yang membutuhkan yaitu jumlah nilai rata-rata waktu 8,2 detik dan dari segi keandalan alat, sensor infrared lebih tinggi dengan nilai 1, dibandingkan dengan sensor catalytic yang mempunyai keandalan 0,60653. Sensor infrared mempunyai keunggulan mendeteksi gas selain gas metahane seperti prophane, ethane, ethylene dan butane. Keunggulan lain yaitu mampu mengadaptasi dengan temperatur tinggi dibandingkan sensor catalytic dengan temperatur rendah.
