Several algorithms have been introduced to increase the accuracy of the heart rate calculation for this type of ECG. This study aims to compare the accuracy of two heart rate calculation algorithms: Filter-Based and Peak Threshold. Both algorithms were implemented into a wearable ECG prototype comprising AD8232, 8-bit microcontroller (ATMega328), and Bluetooth. ECG signals and heart rate (in Beat per Minute (BPM)) were sent via Bluetooth and displayed in real-time on a Windows-based application created using Visual C #. Experiments were conducted on 10 healthy subjects aged 20.4 ± 2.0 years and body weight of 60.8 ± 10.2 kg. The measurement results calculated by using Filter-Based and Peak Threshold were compared to a commercial wearable ECG (Kinetic<sup>TM</sup>) as a ‘ground truth’. The test results showed that the Filter-Based algorithm resulted in a more accurate calculation with the Root Mean Square Error (RMSE) of 1.53, compared to the Peak Threshold algorithm with RMSE of 2.69.</p> Desima Klaudia Hasibuan Indra Hardian Mulyadi ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-sa/4.0/ 2018-10-31 2018-10-31 10 2 54 58 10.30871/ji.v10i2.983 Robot Pengikut Posisi dengan Menggunakan Filter Warna HSV https://jurnal.polibatam.ac.id/index.php/JI/article/view/969 <p>Advancement in digital processing technology have benefited to the human. One of the benefits of image processing is to improve the quality of an image, eliminate noise in and identify objects. By utilizing the technology, it can be developed a system that can detect and track objects. In this article, we develop a system to detect and track an object. We use the HSVcolor filter, erosion, dilation, and thresholding methods to detect the object. To measure the distance between object and robot, we apply the mathematical regression formula. The output of the equation is then used as actuator for the dc motor. The results achieved in this study is system can detect object in the distance range 50-180 cm and follow the object in the range 60-150 cm.</p> Fitrah Triatmojo Budi Sugandi ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-sa/4.0/ 2018-10-31 2018-10-31 10 2 59 63 10.30871/ji.v10i2.969 Digester tipe Balon untuk Pembangkit Listrik Tenaga Biogas di Peternakan Sei Temiang Batam https://jurnal.polibatam.ac.id/index.php/JI/article/view/940 <p>Sei Temiang Livestock in Batam, produce roundabout ±50 m<sup>3</sup> of cow faeces each month. Usually, some of this waste is taken away by villagers to be used as raw material of fertilizer. To increase its value, the excrement can be utilized as source of alternative energy before the remnants are applied as organic manure. This research use baloon type as the digester of biogas power plant due to reasons such as simple installation, easy to be overhauled, and the cost is quite affordable. This prototype use a mixture of cow excrement and water with proportion of 1:1. Gas equivalent to 624 litre can be gained from 1 plastic drum which is able to turn on the electricity for 35 minutes with power capacity of 700 watts.</p> Qoriatul Fitriyah Dedi Irawan Muhammad Prihadi Eko Wahyudi ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-sa/4.0/ 2018-10-31 2018-10-31 10 2 64 67 10.30871/ji.v10i2.940 Alat Pengendali Arus pada Mesin DC-400 Berbasis Mikrokontroler dan Android https://jurnal.polibatam.ac.id/index.php/JI/article/view/907 <p>Power source is a device that serves to supply electrical current in type of welding SMAW (Shield Metal Arc Welding), an example is DC-400 machine. The output current of machine is set using a knob on the output control panel in order to generate heat as needed welding. Along with the development, welder realized that there are limitations in the way of controlling current on the machine. Distance control that requires users to go directly to the machine caused inefficiency in work. Therefore, we need a controller for adjusting the output current from long distance. It is necessary to create "Current Control Device for DC-400 Machine Based Microcontroller and Android". This device can adjust the output current value from long distance and wireless which is a microcontroller as the central controller and android as the input source. From the results of research, the greater value of R1 in potentiometer is set, the greater welding current is generated. The average error between the welding current using the knob and remote is 4.65%.</p> Didi Istardi Muhammad Abdul Ghafur Nugroho Pratomo Ariyanto ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-sa/4.0/ 2018-10-31 2018-10-31 10 2 68 73 10.30871/ji.v10i2.907 Kipas Angin Pengikut Manusia Berdasarkan Wajah https://jurnal.polibatam.ac.id/index.php/JI/article/view/906 <p><em>Technological advances make the need for an automated system increases, one of which makes the fan can track the human automatically. In this study&nbsp; to develop a fan system that can track human based on the face and can distinguish the face with other obstacles around it, so that humans do not need to manually set in directing the fan to get the wind from the fan. To detect human faces used cameras from android smartphones that have been integrated with the Haar Cascade detection method available in the OpenCV library. While to do tracking then used PID controller with Zigler Nichols tuning method which integrated with DC motor. Based on the results of experiments the system can track the human face with an average error of 4.14%, while testing on face detection has a 100% success rate in the face of the frontal. While the system can track human based on the face with 95% success. The error is caused by the mechanical system of dc motor gearbox and camera hardware position that is not straight to the face object.</em></p> Wahyudi Prasatia Kamarudin Kamarudin ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-sa/4.0/ 2018-10-31 2018-10-31 10 2 74 79 10.30871/ji.v10i2.906 Rancang Bangun Penampung Sampah Laut Portable (PSP) dan Uji Solar Panel untuk Mengurangi Sampah Laut https://jurnal.polibatam.ac.id/index.php/JI/article/view/840 <p>Marine litter is waste created by human that has been discharged into the coastal or marine environment. Varied and widespread human activities can act as the source of marine litter. The sources may be located directly at sea, on the coast or inland. Litters can be transported over long distances and into marine habitat. Accumulation of marine litter can affects habitats, organism ecological function, and develops health problems. The objective of present study was to evaluate portable marine litter collector’s performance for eliminating marine litter. The methods consist of some steps i.e. measuring and comparing collected marine litter amount with the total daily average amount in the tested area which took place at Pantai Biru Sehati, Tanjung Piayu; identifying the size and type of material of the collected marine litter; measuring the scope that can be reached by the prototype; along with identifying oceanographic parameter regarding its effects on prototype performance. The results showed that the performance duration of the prototype on an optimum battery is 1 - 3 hours, 2800 rpm of motor speed, 1 - 4 kg of marine litter as the maximum weight that can be held by the prototype. Furthermore, the identified oceanographic parameters are speed current which was 0.7 m/s. The field test also indicates that the oceanographic parameter affects the prototype performance.</p> <p><strong>Keywords : Design, marine litter, portable marine litter collector, oceanographic</strong></p> Amanda T Siboro Feby Angelin Garizi Siahaan Sarnaen Simanjuntak Muhammad Zainuddin Zainuddin Lubis, 14464173 ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-sa/4.0/ 2018-10-31 2018-10-31 10 2 80 85 10.30871/ji.v10i2.840 Kajian Waktu Etsa dan Penurunan Massa PCB double Layar https://jurnal.polibatam.ac.id/index.php/JI/article/view/987 <p>FeCl<sub>3</sub> Etching is the process of removing certain parts of a material using FeCl<sub>3</sub> with a minimum concentration of 28%. The method used with FeCl<sub>3 </sub>solution is a chemical reaction method and material etched is PCB. This study aims to determine the effect of 3 variations used on PCB mass reduction and etching time. Characterization variation used is PCB plate etched using heating and stirrer (PS), PCB plate etched using heating without using stirrer (PTS) and PCB plate etched without using heating and stirrer (TPTS). After the etching process, the PCB plate is characterized using optical microscopy. Based on the research, the mass reduction value of PS is highest for all variations and the etching time of PS occurs at 5 minutes is the fastest than the PTS (10 minutes) and TPTS (20 minutes).</p> Budiana Budiana Elin Aprilia Mchael Timanta Ginting Budi Sugandi ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-sa/4.0/ 2018-10-31 2018-10-31 10 2 86 91 10.30871/ji.v10i2.987 Metode Balancing Jig Procedure pada Tab Elevator Pesawat Boeing 737-800 untuk Mengurangi Dampak Flutter https://jurnal.polibatam.ac.id/index.php/JI/article/view/845 <p>Primary flight control in aircraft consist of aileron, rudder and &nbsp;elevator, secondary flight control consist of flaps, slats, spoiler and trim tab. Before aircraft in flight, the primary and secondary flight con trol must be confirmed in balanced condition. If in unbalanced condition, flutter will occur when aircraft in flight. Flutter &nbsp;is &nbsp;an &nbsp;aeroelasticity &nbsp;phenomenon, &nbsp;it &nbsp;is &nbsp;a &nbsp;vibration &nbsp;phenomenon&nbsp; that &nbsp;caused &nbsp;aircraft &nbsp;wings "flapping" like a bird.This is because combination from stiffness of the wing structure, aerodynamic, and inertia (weight) from the structure. To avoid the occurrence of flutter, balancing flight control should be done, one of them is elevator tab. Elevator tab often called trim tab in elevator. Trim tab is attached to elevator that located in horizontal stabilizer. It must be confirmed in balanced condition even though elevator tab is a secondary flight control. Balancing tab elevator is by jig method procedure, which is tab must be removed first. Whether the elevator is balanced or not are determined by the value of Tab Assembly Moment (TAM) which is the result gained from this research is 15.22 lbfinch and the tab can be said balance, because according to SRM boeing 737-800 the maximum TAM range is 15.48 lbfinch. If the research obtained a result more than 15.48 lbfinch, the tab must be returned to paint shop, decreasing the load weight from the tab by peeling paint coating. If the decreasing load weight from tab can't be done, the tab is considered "rejected", so it must be replaced with the new one.</p> Lalu Giat Juangsa Putra Dian Saputra Achmad Zahir Saputra ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-sa/4.0/ 2018-10-31 2018-10-31 10 2 92 98 10.30871/ji.v10i2.845
