Wearable and wireless Electrocardiograph (ECG) enables real-time and long-term monitoring of heart rate (i.e. 24 hours). 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 (KineticTM) 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.

FeCl3 Etching is the process of removing certain parts of a material using FeCl3 with a minimum concentration of 28%. The method used with FeCl3 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).

Storage services using Google Drive or DropBox are used freely on the internet. Most of them use Cloud Computing technology. It means that the service on Cloud Computing could be provided quickly and it could minimize the interaction with provider. One of the constraints of data storage personally or professionally is the difficulty to access. There is also security disturbance from the network activity such as denial of service and virus infection. Difficulty to share data also becomes the main constraint to set the limit time of the document shared, with whom, and what access is allowed. These are some of the daily constraints and they disturb the flexibility especially in routine work. Therefore, firewall configuration is needed to minimize those disturbances so that the service could still be accessed.

This paper describes the effect of pulse frequency on the properties of microhardness, porosity and macrostructure in GTAW welding. This study used alluminum 6061 as a base metal and without filler metal. Pulse frequency is varied from 0 Hz to 10 Hz. The macrostructure results showed the maximum penetration depth occured at pulse frequency 6 Hz, while the maximum penetration width occured when did not pulse frequency. Micro hardness testing showed that the maximum hardness occured at pulse frequency 6 Hz while the lowest hardness occured at pulse frequency 10 Hz. AA 6061 welding without metal filler produced porosity which can have an impact on the hardness of the weld metal.

As an alternative energy, the potential of wind power in Indonesia is quite high. Some of the constraints of wind power include the presence of intermittent winds, the average wind speed in the Indonesian is relatively low, or only certain areas that have moderate to high wind speeds, so that winds that are not too tight can cause the turbines not spinning. This study is about modifying a two pole single phase induction motor as a wind pico generator. Modifications made to the squirrel cage rotor induction motor become two poles axial flux permanent magnet rotors. The test results show that a two pole pico generator is not suitable to be applied to wind power units. Electric power produced by high-speed prime mover, above 1000 rpm only 2.53 Watts. Whereas when it is operated at low speed, less than 200 rpm, the maximum output power power only 44 mW.

Archive management for organizations is a necessity. ANRI recommends digital records archive management of evidence. University as one of the organizations also requires digitalization of archive management. In particular, management archives of decision letter documents (SK) are important documents that relate to the history of university activities. Digitalization of archive management helps address the weaknesses of managing damaged, lost and vulnerable manual archives and large management costs. Digitalization efforts are done by developing a computer based archive management application using PHP and MYSQL. This application manages university file archiving transactions centrally in order to keep activity history for decision making and as a shared storage media.
