Abstract

This research is aimed to design a system for detecting safe parking distance using Arduino Uno, aspiring to minimize accident risk while parking. Data and information obtained from reviewing literatures about related research and testing the system. Hardware used includes Arduino Uno Board, Camera, TFT LCD Screen (Thin Film Transistor Liquid Crystal Display), Ultrasonic sensor, and a buzzer. Camera and Ultrasonic Sensor placed behind of vehicle which can help user in parking. Picture data obtained from Camera then displayed on TFT LCD which are placed on dashboard. To improve system accuracy, ultrasonic sensor are placed on rear bumper of the vehicle for reading distance which results are displayed to TFT LCD Screen and signals in sound. In result, sensor call still read well distance of the object if the position parallel to the object, when sensor position above object, sensor can read at a certain distance. Position of objects that get closer to the sensor make the level of sensor readings accuracy higher. Moreover in Camera OV7670 testing, Camera still can capture image well in the room that much light, whereas in the room less light images produced blurry.

Abstract

Dalam mengembangkan sistem jaringan sensor, pengembang umumnya menggunakan bahasa pemodelan Unified Modeling Language (UML) untuk proses analisis dan rancangan sistem. Meskipun UML merupakan bahasa pemodelan yang efektif namun dipandang masih memiliki keterbatasan apabila digunakan dalam mendefinisikan beberapa spesifikasi dan aktifitas rancangan sistem. Olehnya itu dikembangkanlah System Modeling Language (SysML) untuk melengkapi keterbatasan yang ada pada UML tersebut. Penelitian ini bertujuan untuk menerapkan System Modeling Language pada pemodelan jaringan sensor nirkabel, secara khusus sistem monitoring lingkungan. Pengumpulan data dilakukan melalui studi literatur dan evaluasi sistem di atas platform arduino. Studi literatur merujuk pada penelitian sebelumnya yang menggunakan Unified Modeling Language (UML) dan pendekatan pengembangan Lightweight Process dalam memodelkan sistem jaringan sensor. Dalam penelitian ini, dua diagram SysML yaitu requirement dan parametric diagram digunakan sebagai karakteristik pemodelan sistem jaringan sensor berbasis SysML. Requirement diagram digunakan untuk mendefinisikan spesifikasi (requirement) sistem dan memetakannya kedalam diagram usecase, sementara parametric diagram digunakan untuk mendefinisikan kendala pada nilai parameter sistem seperti kinerja, keandalan, dan properti massa untuk mendukung analisis teknik dan dipakai untuk mendapatkan sebagian kode implementasi untuk platform mikrokontroller Arduino. Selain itu, evaluasi kode program yang dihasilkan di atas platform Arduino dengan dua node yaitu node sensor dan sink memperlihatkan sistem monitoring yang dikembangkan menggunakan bahasa SysML dapat melakukan pengindraan data temperatur dan kelembaban udara, mengirim data tersebut ke sink dan menampilkan hasilnya di komputer penerima.

Abstract

Pemakaian sistem-sistem monitoring kondisi lingkungan berbasis sensor memiliki berbagai tantangan dan kendala dalam implementasinya seperti kondisi lingkungan yang keras, tidak tersedianya infrastruktur energi dan komunikasi, perubahan cuaca, termasuk jika ditempatkan di sungai yang langsung bersentuhan dengan air dan arus sungai yang deras. Oleh karena itu penelitian ini bertujuan untuk merancang prototip node sensor yang dapat digunakan sebagai sistem monitoring kondisi air sungai. Rancangan perangkat keras prototip terdiri dari mikrokontroller arduino, sensor temperatur, modem SIM800L, baterai dan cover pelinfung node, sementara perangkat lunak node dirancang menggunakan bahasa C++/arduino dan untuk penerima data di server menggunakan PHP. Hasil uji coba prototip yang ditempatkan di sungai jeneberang kota Makassar memperlihatkan bahwa prototip node dapat mengirim data sensor ke internet pada sensornet.kharisma.ac.id untuk disimpan dan diolah lebih lanjut. Dari data yang dikirim secara realtime terlihat bahwa temperatur air bernilai dibawah 500 atau berkisar diangka 300.

Abstract

Penelitian ini bertujuan untuk merancang sistem pemantau kesehatan pasien berbasis jaringan sensor nirkabel yang berbiaya rendah. Teknik pengumpulan data dilakukan melalui studi literatur dan eksperimen prototipe di laboratorium software engineering STMIK KHARISMA Makassar. Untuk memantau kondisi kesehatan pasien secara berkala dari jarak jauh, prototipe sistem pemantau kesehatan berbasis jaringan sensor nirkabel yang dirancang dapat digunakan. Prototipe node sensor terdiri dari Arduino nano, modul komunikasi NRF24L01, sensor detak/pulse, sensor temperatur DS18B20, dan baterai sebagai sumber energi node. Sedangkan node sink/gateway disusun dari Arduino Uno, NRF24L01 dan modul timer RTC. Dari hasil evaluasi penginderaan node sensor diperoleh data detak jantung responden orang dewasa dengan kondisi sehat berkisar 62-71 BPM dan suhu tubuh sekitar 34-35 derajat Celcius. Rata-rata persentase perbedaan relatif terhadap pengukuran menggunakan alat manual atau tanpa menggunakan prototipe untuk sepuluh sampel data detak jantung yaitu 3,37%, dan data temperatur sebesar 2,48%.

Abstract

The purpose of this research is to design over the air programming mechanism for a node in wireless sensor network. Data are gathered from experiments of the proposed system on a constrainted environment. On this design, the Arduino that becomes the target of reprogramming has it’s bootloader modified to enable the capability to run embedded program from the SD Card. Arduino’s source code .ino file is compiled into a .hex file using the Arduino IDE. Then, it is processed using avrdude application into a ready to run firmware binary file on Arduino. A desktop application is made for this mechanism in order to control sender XBee device in transmitting data packet by packet. If the transmission was successful, the node will restart itself, and trigger the bootloader to load new program from the SD Card. The system is evaluated through preset scenarios which including testing at various distances and environments (indoor and outdoor). It was concluded that the reprogramming mechanism was uneffective in transmitting source code when at least one of the XBee devices is located inside the building which affected the transmission process. For the second testing scenario, both nodes were located outdoors with testing distance up to 15 metres, resulting with average transmission speed of 35 bytes per second for sent packet size of 60 bytes. The safest sent packet size to avoid packet loss while transmitting should not exceed 30 bytes for transmission distance up to 15 metres. Transmission speed across all test scenarios ranges between 14 bytes per second to 35 bytes per second. For indoor testing, the evaluation results showed that the designed OTAP mechanism in this study is not yet effective. This is assumed to be influenced by the transmission capability of the XBee communication module.

Abstract

This study aims to create an Short Message Service (SMS) based security system using the Arduino platform, where the system can be applied to every corner of the village in Indonesia. The system functions to play the sound of the danger signal whether it is theft or fire. The method used to remotely or or control the system is to use the Short Message Service (SMS) Tracking method, namely by sending an SMS command to play the sound of an alarm (Mp3). The system can run well such as receiving sms and processing the contents of the sms to play mp3 files, although there is still a little delay in receiving sms and playing the mp3.

Abstract

This study aims to design an efficient calorie counter application using Model-View-ViewModel (MVVM). The use of the Model-View-ViewModel design pattern is based on efforts to facilitate the process of reusing source code (Reusability). The design process uses flutter as an application framework. This research can be used as a reference regarding the Model-View-ViewModel, as well as providing new knowledge for researchers regarding the combination of the Model-View-ViewModel design pattern with the flutter framework on the android platform. Data collection in this study was carried out through literature studies and evaluation of the system design. The application was developed using the Dart programming language, while the evaluation of the implementation of MVVM design pattern is measured by using CK metrics. The evaluation shows that the MVVM calorie counter application can be run on Bluestacks Android Emulator successfully. The reusability degree of the application is better than the non-MVVM calorie counter apps, where the WMC parameter decreased by 4.5 points, and the DIT parameter by 0.3 points, while the CBO parameter decreased by 0.4 points, and the LCOM parameter by 31.2 points. The results indicate that the MVVM calorie counter application is easier to maintain.
