Acquisition and Data Logging Inertial Navigation System (INS) on Combat Submarine Using Arduino-SD Card
Get PDFIn a combat submarine operating system, navigation device acts as a location information provider on inside or at sea level. Such information is position data provided by GPS (Global Positioning System) and data transmitted by IMU (Inertial Measurement Unit) sensor. Combining these two device is called INS (Inertial Navigation System). This inertial sensor interacts using serial communication data, however records are needed to collect, store and store incoming data in order to be processed easily. Data logging process is feasible as a recorder and data storage using SD Card. Enhancements, such as SD cards are needed because in general system is equipped with a small memory capacity. Arduino is a microcontroller that can assist in process because data obtained from sensor is processed using serial communication lines (RX and TX). Results obtained from calculation and logging data are calculation Roll, Pitch, Heading, Latitude, Longitude, Microseconds, Gyroscope on X axis, Y, Z, Accelerometer on X axis, Y, Z, Magnetometer on X, Y, Z, Velocity North, East, Down. This proves that system acceleration and data logging using Arduino and SD Card can assist in obtaining information and KTBA situation

Study the Duration of Steam Power Plant’s Maintenance to Improve the Equivalent Availability Factor
Get PDFPeriodic maintenance of power plants is included in the project. Shorter project duration than scheduled indicates the success of the project. For the electricity industry, operating earlier will increase the availability index, which in turn will increase revenue. The standard maintenance work scope of the power plant owner is presented in a detailed work structure of the project as known as Work Breakdown Structure (WBS). Project scheduling is done using network technique with the Critical Path Method (CPM). All activities that are on the critical path can be done crashing to speed up work in shortening the duration of treatment. Crashing is done by utilizing the cost slope of critical activities. So information can be obtained about the costs of several possible durations. The study of power plant maintenance using a cost slope gets an accelerated duration with the smallest cost, which is 28 days. With a maintenance duration of 28 days the total cost is 3,854,670,611 rupiahs and with an additional income of 429,643,368 rupiah from normal income of 21,404,712,886 rupiah
Analysis Suppliers Selection of the Construction Raw Material in PT. Y Using VIKOR Method
Get PDFImproving supply chain management is one way to excel in competition. The selection of suppliers is an important part because the lack of proper supplier selection can lead to losses for the company. In its practice, the supplier selection process is more frequently based on a supplier that can provide the lowest price. This happens because the supplier selection process is considered to be at the operational level and not at the strategic level. The number of raw material suppliers on the construction project makes the developers be careful in choosing the material that is according to the developers’ plans. All this time, the selection of suppliers involves many factors, sometimes a supplier has a good performance in terms of the delivery process, yet lacks in terms of quality compared to other suppliers and vice versa. Therefore, research must be done with a method that can take the factors, both the qualitative and quantitative, into consideration.
