Abstract

Intisari---Penelitian inimengusulkan sebuah algoritma berbasis komputer sebagai alat bantupemeriksaan laboratorium dalam mengidentifikasi anemia secara efisien dan denganbiaya yang murah. Algoritma yang diusulkan terdiri dari tiga proses utama, yaitu pengolahan citra, ekstraksi fitur, dan proses identifikasi. Proses pengolahan citra dilakukan dalam dua tahap, yakni ­pre-processing dan segmentasi. Pada proses ekstraksi fitur, dilakukan penyusunan vektor fitur berdasarkan keluaran dari proses pengolahan citra. Vektor fitur ini menjadi masukan dalam proses identifikasi otomatis anemia dannon-anemia pada citra sel darah merah menggunakan metode K-Means. Algoritma yang diusulkan digunakan pada 92 buah citra sel darah merah, dengan rincian 52 buah citra terindikasi anemia, dan 40 buah citra kategori non-anemia.Hasil identifikasi untuk seluruh citra sel darah merah divalidasi dengan membandingkan keluaran dari K-Means dengan hasil identifikasi oleh tenaga medis. Dari proses validasi, didapatkan nilai akurasi sebesar 94.5%, yang menunjukkan bahwa algoritma yang diusulkan mampu mengidentifikasi anemia dan non-anemia secara efektif.Kata kunci--- Anemia, Citra sel darah merah, Idenfikasi, K-Means, Komputer                                      Abstract--- This research workproposes a computerized algorithmto perform an efficient and low-cost anemia identification.

Intisari--- Pada penelitian ini, salah satu modul termoelektrik, yaitu efek peltier, dimanfaatkan untuk membuat kotak pendingin dan penghangat. Arduino uno digunakan untuk mengolah hasil pembacaan sensor dan memutus daya secara otomatis jika suhu di atas setting point. Kinerja kotak tersebut kemudian diuji dan dianalisa dalam keadaan dengan beban dan tanpa beban pada berbagai kondisi. Dari hasil pengujian diketahui bahwa instrumen ini memiliki suhu maksimal penghangat sebesar 38oC dan suhu pendingin minimal sebesar 19,5o C. Efek dari arus, suhu lingkungan, dan dimensi ruang juga telah dianalisa, yang menunjukkan bahwa alat ini dapat bekerja dengan cukup baik.Kata kunci--- Termoelektrik, efek peltier, arduino uno.                                      Abstract--- In this research, one of thermoelectric module, i.e peltier effect, is used as a cooler and warmer box. Arduino uno has been used to process an input from sensor and cut off power supply if temperature more than setting point automatically. The performance of the box then be measured and analysed with and without a load under several conditions. From the measurement results, it has been known that the instrument reach maximum temperature at warm side is about 38oC and at cool side is 19.5oC. The effects of current, ambient temperatures and box dimensions also have been analysed, indicating that the instrument has a quite well performance. Keywords--- Thermoelectric, peltier effect, arduino uno.

Metode penelitian yang dilakukan berupa perancangan (perancangan perangkat keras dan aplikasi pada smartphone)  dan pengujian (pengujian subsistem dan pengujian sistem keseluruhan). Data penelitian berupa data hasil pengujian subsistem komunikasi Bluetooth, deteksi GPS, komunikasi GSM, dan rele.Pengiriman data antara Bluetooth Module dan Bluetooth pada smartphone dapat mencapai 10 meter.Akurasi GPS Receiver yang digunakan adalah kurang dari 7 meter.Terdapat selisih 4 m hingga 18 m pada penentuan posisi kendaraan yang dilakukan oleh sistem dan smartphone.Hal ini dikarenakan kondisi lingkungan sangat berpengaruh terhadap akurasi data GPS yang diperoleh.Kata kunci--- GPS, GSM, Bluetooth, Sistem Keamanan, Smartphone.                                      Abstract--- Design of motor vehicle security system based on GPS and Bluetooth connection on android smartphone equipped with an emergency safety feature with accruracy and precision that support the realization of interactive security system. This research method was done by  design (design of hardware and applications on smartphones) and testing (testing subsystems and the overall system testing). The research data is data communication subsystem test result Bluetooth, GPS detection, GSM communication and action relay. Data transmission between Bluetooth module and Bluetooth on the smartphone can reach 10 meters.Accuracy  GPS receiver that is  used is less than 7 meters. There is a differenceof  4 m to 18 m in the positioning of vehicles carried by the system and smartphones. This is because  environmental conditions greatly affect the accuracy of GPS data obtained.Keywords--- GPS, GSM, Bluetooth, Security System, Smartphone.

Abstract

Intisari--- Indonesia merupakan negara beriklim tropis yang mempunyai keanekaragaman jenis satwa. Beberapa di antaranya adalah satwa yang dikategorikan terancam punah. Hal ini disebabkan karena banyaknya praktik perburuan liar dan semakin  menyempitnya hutan sebagai tempat tinggal. Oleh karena itu, perlu dilakukan pengawasan dan perlindungan terhadap satwa-satwa tersebut. Paper ini mengusulkan perancangan camera trap untuk pengawasan satwa secara otomatis. Camera trap digunakan untuk memudahkan konservasi dalam mendata dan memantau penyebaran satwa. Camera trap dapat mengambil gambar secara otomatis jika satwa melintas di depannya. Pada penelitian ini digunakan raspberry Pi 2 sebagai pengendali utama, sensor PIR HC-SR501 sebagai piranti pengindera pancaran inframerah dari objek, modul RTC DS1307 sebagai penentu waktu, rangkaian LED IR membantu pencahayaan di malam hari dan flashdisk sebagai media penyimpanan gambar. Hasil penelitian ini menunjukan bahwa rancang bangun sistem dapat mengambil gambar secara otomatis dengan jarak jangkauan sensor PIR tertinggi pada sudut 0° sejauh 6 meter. Alat ini dapat bekerja rata-rata selama 20,8 jam. Pada lingkungan yang gelap, alat ini mampu mengambil gambar objek secara jelas dengan jarak maksimal 3 meter dan dapat menyimpan hasil gambar secara realtime.Kata kunci--- Camera Trap, Otomatis, Konservasi, Inframerah, Raspberry Pi 2.                                      Abstract--- Indonesia is a tropical country that has a diversity of wildlife species. Some of them are animals that are categorized as endangered. This is due to the abundance of illegal hunting practices and the narrowing of the forest as a place to live. Therefore, it is necessary to supervise and protect that the animal. This paper proposes the design of camera traps for automatic monitoring of the animals. Camera traps are used to facilitate conservation in data collections and monitoring of animal dispersal. Camera traps can take pictures automatically if the animal passes in front of them. This research proposes the use of Raspberry Pi 2 as the main controller, PIR HC-SR501 sensor as a device of the sensing an infrared from the object, RT1307 RTC module as a timer, IR LED series helps night lighting and a flash disk as a storage image. The research results showed that the design of the system can take pictures automatically with the distance of the highest PIR sensor at an angle of 0 ° as far as 6 meters. The appliance can work on average for 20.8 hours. In dark environments, this tool is able to capture images of objects clearly with a maximum distance of 3 meters and can store images in real-time.Keywords--- Camera Trap, Automatic, Conservation, Infrared, Raspberry Pi 2.
