Abstract

Abstrak Webcam pada umumnya digunakan sebagai media komunikasi dunia maya. Namun pada model sistem monitoring yang direalisasikan, penulis menggunakan webcam sebagai sensor yang mengganti indra penglihatan untuk melakukan monitoring di dalam ruangan. Dalam melakukan monitoring, webcam dapat digerakkan secara horizontal dan vertikal menggunakan 2 buah motor servo yang dikendalikan oleh mikrokontroller Atmega 16. Pada model sistem ini, dikembangkan pula program motion detection untuk mendeteksi adanya pergerakan di dalam ruangan. Jika terjadi pergerakan, maka tampilan gambar dari webcam akan direkam pada PC, dan mikrokontroler akan mengaktifkan buzzer.  Karena webcam memiliki keterbatasan pencahayaan ketika ruangan gelap, maka dilakukan penambahan modul infra merah yang dilengkapi sensor LDR. Dengan modul ini, pergerakkan di dalam ruangan yang gelap dapat terdeteksi sejauh 6 m. Untuk jarak antara ruang pengawas dan ruang yang dipantau, didapatkan panjang kabel sejauh 10 m. Kata kunci: webcam, program motion detection, mikrokontroler ATMega16, motor servo, buzzer. ABSTRACT Webcam is generally used as a medium of cyberspace communication. However, the monitoring system model that was realized, the authors used a webcam as a sensor that replaced the sense of sight to monitor in the room. In conducting the monitoring, the webcam could be moved horizontally and vertically using 2 pieces of servo motors were controlled by microcontroller Atmega16. In this model system, it was also developed a motion detection program to detect movement in the room. If there was movement, the display image from the webcam would be recorded by the PC, and the microcontroller would activate the buzzer. Since the webcam had a limited lighting when the room was dark, so at it was required a module additionthat equipped with infrared sensor LDR. By this module, the movement in the dark room could be detected as far as 6 m. For the distance between supervisor and monitored rooms, it was as far as10 m cable length. Keywords: webcam, program motion detection, microcontroller ATMega16, servo motor, buzzer.

Abstract

Activities such as planting and gardening become one of prominent hobbies. An issue of having such well grown plants is the impractical and unachieavable task to monitor 24 hours a day, thus we need a smart gardening system that can monitor the garden on demand. One of the problems in residential gardening systems is how to water the plants while the owner is not at home. Some of people have an adequate knowledge of using IoT to make their life easier. This paper proposes a simple automatic gardening system in watering several plants as programmed. In addition, this system allows human’s manual intervention either locally or remotely via Internet, to control a water pump. To build this smart gardening system, we use Xiaomi home application from Google Play. In this application, we can set the program to water the plants daily with definite time periodic independently.

Nowadays, security and gardening systems in densely populated residential areas are generally done manually. The security system in housing sometimes places security posts at street corners that are some distance from citizen’s homes thus they cannot be monitored at all times. Whereas other problem of watering system in citizen’s homes, someone has to water the plants one by one that it is not efficient in  energy, time and water availability thus that it can reduce the quality of the plants. Internet of Things (IoT) is a concept and method for remote control, monitoring, and various tasks. IoT is connected to a network that it can be accessed anywhere which can make things easier. IoT can be used to solve various problems. One of them is security issues and gardening activities. By using smart home technology, the security system is carried out by placing CCTV (Closed Circuit Television) which can be accessed by the home owner, anytime and anywhere the home owner is located. On the other hand, gardening is one of the most popular hobbies. In this field, IoT can be used to monitor and regulate various things to support gardening activities. In this community service activity, we are proposed a simple automatic gardening system for watering some plants programmatically in Pondok Hijau Indah residence.
