Abstract

AbstractSuatu data atau informasi disajikan tidak hanya berupa data teks tetapi juga dapat berupa audio, video, dan gambar. Pada zaman sekarang, informasi sangatlah penting dan diperlukan, begitu juga informasi yang terdapat pada citra. Citra (image) atau istilah lain untuk gambar merupakan salah satu komponen multimedia yang berperan penting sebagai bentuk informasi visual. Dibandingkan dengan data teks, citra memiliki banyak informasi. Namun terkadang citra juga dapat mengalami penurunan yaitu degradasi atau penurunan kualitas yang disebabkan oleh derau / noise, warna terlalu kontras, kabur, dan lain-lain. Ada beberapa jenis noise dalam pengolahan citra salah satunya yaitu salt & pepper noise. Noise salt & pepper berbentuk seperti bintik hitam dan putih pada citra. Untuk mengurangi noise dibutuhkan suatu metode, salah satunya yaitu median filter. Pada makalah ini, citra yang bernoise salt and pepper, setelah direduksi menggunakan median filter, gambar yang bernoise tersebut langsung menjadi sebuah citra yang bersih yaitu citra yang dihasilkan sesuai dengan gambar aslinya.

Abstract

Ornamental plants are used to decorate the room or the yard. In the current technology era where everyone has a high level of activity, it sometimes makes them forgot to pay attention to the ornamental plants in their homes. Therefore, the purpose of establishing this plants monitoring system is to determine the condition of the plant by displaying smile and sad face images on the LCD. This system uses a microcontroller likes Arduino Nano as the main controller and connected to other sensors such as the LDR sensor, soil moisture, and DHT11. The results of this study indicate that the ornamental plant is in good condition if it displays happy face, that is when the results of the lighting, soil moisture, and temperature are obtained accordance the values set in the program. Otherwise, if the system displays a sad face, it shows that the condition of the ornamental plants is not good because of the lack of lighting, soil moisture, and low temperatures received by the ornamental plants. The values set on the soil moisture and lighting sensor are in the range of 50% to 95%, while the values set on the temperature sensor are in the range of 15°C to 35°C.

Abstract

The lungs are one of the important organs in the human body. Because the lungs are one of the holders of control in the circulatory system in the human body. According to some internal medicine specialists, the lungs are the most vulnerable internal organs to damage, this is due to lung function that comes in direct contact with the outside environment such as inhaled cigarette smoke, vehicle fumes, or is allergic to something. So that the lungs are hollow and eroded. Therefore detection of human lungs is needed. To find out damage to the lungs, a CT scan image process is needed. In CT-Scan images there is information that is used to analyze and know the shape of an object from the lung itself. To obtain this information, it is necessary to do a segmentation process. In this study using the Active Contour method. Active Contour is a segmentation method that is often used because this method uses a closed curve model that can move wide or narrow. The purpose of this study was to segment the lungs on CT-Scan images by using the active contour method to determine the value of the area and perimeter of the lung section that was good and to find the accuracy value of the method used for a CT-Scan image. The results of lung segmentation were carried out a system trial carried out on 15 CT-Scan image data obtained an average accuracy of 80%
