<![CDATA[Kasus tindakan pencurian dan perampokan semakin marak terjadi. Para pelakunya tak segan untuk melukai ataupun membunuh korbannya dan sering beraksi pada minimarket, toko, gudang dan rumah yang dalam keadaan sepi. Rumah kos cenderung menjadi incaran kawanan pencuri/perampok, karena kebanyakan penghuni rumah kos adalah mahasiswa dan karyawan yang sering menghabiskan waktu diluar. Sistem keamanan rumah kos saat ini adalah CCTV (Closed Circuit Television). Sistem ini dirasa masih belum cukup untuk menjaga keamanan rumah kos dari bahaya pencurian/perampokan, dikarenakan sistem CCTV ini hanya mampu memantau dan merekam segala aktivitas atau kejadian yang telah terjadi. Berkembangnya teknologi informasi dan komunikasi telah membawa kamajuan diberbagai macam bidang, terutama pada bidang pengolahan citra (Image Processing). Pada penelitian ini penulis bermaksud membuat sebuah sistem keamanan yang mengimplementasikan pengolahan citra dalam mengidentifikasi bahaya pencurian/perampokkan di area pengawasannya. Hasil dari penelitian ini adalah pengujian kemampuan pendeteksian pergerakan area pengawasan, pengujian report dan notifikasi pengiriman SMS pemberitahuan, pengujian penyeleksian area pengawasan serta pengujian pengaruh perubahan nilai toleransi piksel (nilai sensitifitas) terhadap akurasi pendeteksian pergerakan.]]>

<![CDATA[Many types of antennas can be used for digital TV receivers; in this article we try to design a double biquad antenna. This is due to a simple form, easy to make, a wide beamwidth. In designing a digital TV receiver for the Malang area, an STB device is needed, so that analog TV can still receive digital TV broadcasts. In this study, the antenna is made of copper wire, each side length: ¼ ? , with a working frequency: 650 MHz. In order to match the impedance of the 75? coaxial cable with the antenna, a balun 4:1 is required. The research place is in the Polinema Telecommunications laboratory. The test results show that the lowest return loss (RL) occurs at a frequency of F=605 MHz, namely RL: -17.8 dB, for a frequency of F=650 MHz, the magnitude of RL: -11.3 dB. The large VSWR antenna at the working frequency F: 650 MHz is 1.46. So that it can be said that it has fulfilled the antenna parameters, namely VSWR < 2. It means that there is a power loss of less than 10%. The largest antenna gain occurs at a frequency: 400 MHz namely: 14.85 dB,. While the average gain of the antenna is 2.21 dB. The antenna radiation pattern is omni directional. The double biquad antenna is very good for use as a digital TV receiver for the Greater Malang area, either without using a reflector or with a reflector.]]>

<![CDATA[Dalam hal penetasan burung lovebird, masalah yang sering dihadapi adalah bagaimana menetaskan telur burung dalam jumlah banyak dan dalam waktu yang bersamaan. Sedangkan kapasitas dan waktu yang dibutuhkan induk burung dalam mengerami telurnya yaitu maksimal 6 butir telur tiap satu induk burung dalam waktu 21 hari, masalah lain adalah lamanya induk burung untuk mereproduksi telur setelah bertelur karena harus memelihara anaknya sampai siap untuk bertelur kembali.Perilaku induk burung yang terkadang tidak mengabaikan telur yang sedang dierami juga menjadi masalah yang sangat merugikan para peternak burung lovebird. Maka untuk menggantikan induk burung dalam menetaskan dibuatlah mesin penetas telur burung lovebird berbasis mikrokontroler dengan fuzzy logic controller yang bertujuan untuk mengontrol suhunya agar sesuai set point, sehingga diharapkan tidak terjadi fluktuasi suhu dalam mesin tetas. Rak pemutar rak telur juga dirancang agar dapat berputar secara otomatis. Juga dilengkapi kipas untuk meratakan suhu dalam mesin.Setelah dilakukan pengujian dari sistem yang telah dirancang, dapat diperoleh waktu yang dibutuhkan dalam proses menetasakan telur burung lovebird adalah 22 hari dengan tingkat keberhasilan 93%. In the case of lovebird hatching, the problem often faced is how to incubate large numbers of bird eggs at the same time. Whereas the capacity and time needed by the mother bird to incubate the eggs is a maximum of 6 eggs per one mother bird within 21 days, another problem is the length of the mother bird to reproduce eggs after laying eggs because they have to keep their children ready to lay eggs again. The behavior of mother birds that sometimes do not ignore the eggs that are being incubated is also a problem that is very detrimental to the lovebird breeders.To replace the mother bird in hatching a microcontroller-based bird hatcher machine was made with a fuzzy logic controller that aims to control the temperature to match the set point, so that temperature fluctuations in hatching machines are expected to not occur. Egg rack rack is also designed to rotate automatically. Also equipped with a fan to even the temperature inside the engine After testing of the system that has been designed, it can be obtained the time needed in the process of lovebird bird eggs is 22 days with a success rate of 93%.]]>

<![CDATA[Saat ini banyak etalase tempat penyimpanan makanan yang diletakkan di rumah sakit maupun di masjid/mushola dengan tujuan berbagi makanan. Tempat penyimpanan makanan (food box) dapat diisi oleh siapapun (sukarelawan) dan dapat digunakan oleh siapapun. Permasalahan yang sering terjadi adalah tempat penyimpanan makanan ini seringkali dalam keadaan kosong, hal ini dikarenakan sukarelawan kesulitan dalam mendapatkan informasi stok makanan yang tersedia didalam box. Selain itu sukarelawan kesulitan dalam hal pemesanan makanan ke warung dan pendistribusian makanan. Maka dari itu, pada penelitian ini dirancang alat Smart Food Box yang dapat memonitoring ketersediaan stok makanan dalam box yang dapat diakses melalui smartphone. Studi kasus yang diambil adalah untuk penunggu pasien di rumah sakit. Smart Food Box pada penelitian ini menggunakan sensor ultrasonik untuk mengetahui level ketinggian dan sensor Load cell sebagai pendeteksi nilai berat dalam box tersebut. Untuk monitoring jarak jauh menggunakan mikrokontroller Arduino ESP 32 berbasis IoT (Internet of Things). Selain itu akan dibuat suatu aplikasi yang dapat dipergunakan oleh sukarelawan dalam pemesanan makanan ke warung terdekat dan pendistribusisan makanan akan diantar langsung oleh pihak warung ke Smart Food Box yang berada di rumah sakit. Dari hasil pengujian Smart Food Box didapatkan bahwa aplikasi berjalan sesuai tujuan, yaitu perubahan nilai yang dibaca oleh sensor dapat ditampilkan dengan baik di aplikasi sesuai dengan jumlah makanan yang dimasukkan maupun diambil dari Smart Food Box. A food box is a box that can be used to share food with others. Volunteers usually fill the box with food, and other people who need food can get the food without any fees. The food box usually could be found at the mosque, hospital, and any other public facilities. But, the lack of information on food stock provided to the volunteers, sometimes makes the volunteers do not have enough information on when they must refill the box. This research aims to provide a Smart Food Box prototype that can monitor the food stock in the box automatically. Further, food stock information is accessible through smartphones. For the case study, the Smart Food Box is placed at a hospital. This Smart Food Box uses an ultrasonic sensor to get the height level of food inside the box and the load cell sensor to detect the weight of the food inside. And IoT (Internet of Things) based on Arduino ESP 32 microcontroller is used to monitor the box remotely. A mobile application is also developed for volunteers to order food directly to the food shop. The ordered food will be directly sent by the food shop to the Smart Food Box. The Smart Food Box has been tested and it shows good performance. The sensors can gather information on food stock, and the mobile application can show the information to the volunteers accurately.]]>

<![CDATA[Stroke Transient Ischemic Attack (TIA ) adalah kondisi stroke ringan. Stroke ringan diakibatkan oleh berkurangnya suplai darah menuju otak. Kelumpuhan disebabkan oleh kurangnya aliran darah ke otak, sehingga sisi tubuh akan mengalami kelumpuhan terutama pada siku dan lutut. Fisioterapi pada pasien pasca stroke ringan dilakukan dengan metode terapi gerakan antara lain seperti penggunaan alat bantu fisioterapi pasien pasca stroke menggunakan sensor MPU6050 melalui media transmisi Bluetooth. Sistem rancangan ini membantu latihan pada pasien berbentuk sensor MPU6050 yang digunakan untuk mendeteksi sudut serta banyaknya gerakan rehabilitasi pasien pasca stroke. Sensor gyroscope menghasilkan deteksi sudut pada siku sebesar 150 dan sudut pada lutut sebesar 135 . Data yang didapatkan diproses oleh arduino nano menggunakan metode I2C. Penelitian ini bertujuan untuk merancang alat bantu fisioterapi pasien pasca stroke berbasis mikrokontroler guna memperoleh hasil yang maksimal karena bentuk alat ini yang portable. Stroke Transient Ischemic Attack (TIA) is a mild stroke condition that can be caused by reduced blood supply to the brain due to blocked blood vessels. Lack of blood flow to the brain can cause paralysis, usually only on one side of the body such as the elbows and knees. Physiotherapy in post-stroke patients is carried out using movement therapy methods, including elbow and knee flexion. Currently, patients come to the therapist or vice versa to perform therapeutic movements, so a telemonitoring system for post-stroke patient physiotherapy tools is made using the MPU6050 sensor which is connected to ESP 232 and the internet network and can be monitored by therapists and clinic admins where the therapy is done. This system helps monitor elbow and knew flexion exercises using the MPU6050 sensor which is used to detect the angle and number of rehabilitation movements of post-stroke patients. . From the results of testing the accuracy of this sensor is able to detect the angle of elbow movement from 00-1500 and knee flexion angle of 00-1350 by 99%.The telemonitoring application for physiotherapy tools for post-stroke patients based on Android is equipped with a therapist menu so that the number of movements and the average angle of movement of the knees and elbows can be monitored by the therapist, this tool can also be used anywhere and anytime due to the portable form of this tool.]]>
