Abstract

Security label is made to anticipate the increasing of documents falsification trend. In this study, the security label is created using CdSe quantum dots. The quantum dots can be used for casting light according to its wavelength so that the particle size can be specific. That’s why its worth to be security key from quantum dots. The quantum dots that be used is colloidal CdSe quantum dots with a wavelength of 595 nm and 526 nm. In the previous studies have been done the two-dimensional scanning process of quantum dots for one color as a security label. However, the results obtained are not perfect because it has not done the repair process for the image resulted. Therefore, in this study conducted by the two-dimensional scanning of quantum dots in two colors to add a level of security on the label then followed by image processing in order to obtain a better image. Image processing which have been done by observing the histogram of the image in order to obtain a threshold value between the object and the background image. Scanning generate data in the form of a sequence intensity value corresponding to the color intensity of quantum dots to obtain image data processing results. Image processing through the observation of the histogram data successfully get the intensity threshold value so that the image can be processed to become more visible in accordance with the sample

Abstract

Tanah longsor merupakan salah satu bencana yang sering terjadi di Indonesia, terutama di daerah pegunungan, lembah dan perbukitan dengan kondisi lereng yang tidak stabil. Saat musim hujan tiba maka kadar air yang berlebihan mengakibatkan tanah longsor. Bencana tanah longsor dapat menyebabkan banyak kerugian antara lain: kematian, gangguan infrastruktur jalan dan rusaknya lahan pertanian. Hal tersebut dipengaruhi oleh 2 faktor utama yaitu kemiringan lereng dan kelembaban. Penelitian ini bertujuan untuk meminimalkan korban jiwa dengan merancang alat pendeteksi peringatan dini bencana tanah longsor menggunakan sensor Soil Moisture FC-28 dan NodeMcu longsor yang terhubung ke android melalui telegram, sms dan buzzer. Sensor soil moisture FC-28 dipakai untuk mendeteksi parameter kelembaban tanah. Pengujian potensi terjadinya tanah longsor didesain dalam 5 variasi kemiringan untuk mendapatkan nilai kembebaban yang bervariasi. Alat dirancang dengan 2 kondisi yaitu status siaga dan bahaya. Hasil pengujian menunjukkan bahwa kondisi siaga terjadi pada kelembaban antara 27% - 54% dengan kemiringan lereng antara 25o -35o dan kondisi bahaya terjadi saat kelembaban lebih dari 54%. Peringatan dini akan terkirim melalui pesan singkat ada aplikasi telegram messenger saat kondisi status siaga, sedangkan alarm akan berbunyi pada saat status bahaya. Alat ini akan sangat bermanfaat bagi warga yang tinggal didaerah rawan bencana longsor, karena dengan adanya tanda peringatan dini warga diharapkan masih mempunyai waktu untuk menyelamatkan diri sehingga korban jiwa dapat diminimalkan.

Abstract

Research has been conducted on the comparison of the I-V characteristic curve between mathematical study and experiment of the generation of negative DC corona discharge in the Gradient Line-to-Plane (GL-P) electrode configuration. The reason for this research is to calculate the suitability of the corona discharge electrical current between the mathematical and experimental study. The active electrode used has length 2 cm and height 4 cm. This research is conducted with variations in the sharpness angle of the active electrode (θ) 300, 450, and 600 and variations in the distance between the electrodes () 2 cm, 3 cm, and 4 cm. The mathematical formulation of the value of the corona discharge electrical current in the configuration of the GL-P electrode is obtained by using the geometric concept approach, which is the formulation of the capacitance value of the ordinary electrical circuit, with the addition of the multiplication factor value k in the sharp area of the active electrode, because in that area the greatest plasma flow distance is obtained. The value of the multiplication factor  is obtained by fitting the curve between mathematical study and experiments. The I-V curve between the mathematical study and the corona discharge generation experiment has a high degree of similarity with the smallest percentage contacting point of 37.50%.The value of the multiplication factor  is influenced by the sharpness angle of the active electrode shape and the distance between the electrodes.

Abstract

Curah hujan adalah suatu peristiwa turunnya hujan di permukaan bumi yang terjadi diakibatkan oleh uap air yang ada di atmosfer, jumlahnya dipengaruhi oleh faktor iklim seperti suhu, kelembaban, tekanan udara. Namun pada saat ini anomali cuaca yang termasuk curah hujan sangat fluktuatif dan sering terjadi perbedaan pada setiap tempatnya. Maka dari itu dibutuhkan rancang bangun sistem penentuan cuaca yang berorientasi pada suatu tempat tertentu agar didapatkan hasil yang mendekati dengan anomali curah hujan yang terjadi. Sistem ini terdiri atas beberapa komponen input, control, dan output. Komponen input seperti halnya sensor yang digunakan antara lain sensor DHT22, BMP180, dan sensor anemometer, sedangkan untuk komponen control adalah ESP32. Serta komponen keluarannya seperti display LCD 16 x 2 dan aplikasi Blynk. Pada alat ini digunakan jaringan yang sama dengan menggunakan penambatan seluler pribadi melalui handphone yang digunakan untuk memonitoring agar koneksi tetap tersambung dan stabil. Cara kerja alat ini adalah dengan membaca seluruh sensor yang ada dengan kondisi sekitar untuk menghasilkan keluaran berupa penentuan curah hujan. Kemudian masing – masing sensor bekerja sebagaimana sistem pembacaannya seperti sensor DHT22 membaca suhu dan kelembaban, dan sensor BMP180 membaca tekanan. Kemudian setelah proses tersebut dilakukan pengambilan keputusan oleh logika fuzzy dengan metode mamdani yang tertanam pada kode program yang akan menentukan penentuan curah hujan. Hasilnya ditampilkan pada LCD yang terdapat pada alat dan juga dapat dilihat pada Blynk secara realtime. Dari penelitian tersebut didapatkan eror rata – rata pada percobaan yang dilakukan dengan nilai 0,4%

Abstract

Suboptimal fish feeding management can affect the growth rate of fish. Fish   Feeding management consists of aspects of feed nutritional content, quantity, and feeding system. A system that still relies on humans or manual labor is very likely to cause human error in the process, so utilizing technology can be an option to improve the feeding system. This study aims to design and test the Smart Fish Feeder Design as an innovation in technology-based freshwater fish feeding. The fish Feeder works by providing fish feeding scheduling using the RTC DS3231 and detecting vibrations in pond water, which aims to determine the feeding process using the SW-420 Vibration Sensor. If a certain vibration is used as a parameter that the fish are still consuming feed, then the feeding process continues. The duration of the influence of sensor readings in adding feed lasts for one minute and can be adjusted according to pond conditions or the number of research subjects. The results show that the design can provide fish feed on a scheduled basis with high accuracy and can detect water vibrations as an indicator of feed consumption by fish.
