Abstract

The high sensitivity and low power consumption of fiber Bragg grating (FBG), has been widely applied in optical technology to measure temperature and strain. Currently, the need for detection by the industrial sector is increasingly being developed, one of which is the detection of characteristics in honey solutions. The use of FBG as a detector has a great opportunity to see the unique characteristics of the honey solution. Therefore, this problem needs to be followed up by analyzing the effect of honey temperature on the FBG output power, changes in Bragg wavelength, and the rate of temperature change. The research method was carried out by placing FBG in a heated honey solution, then measuring the temperature between 30°C – 60°C with an increase of 5°C. The FBG used consists of a wavelength of 1550 nm and 1310 nm which is fed with 1 mW of input power. The results showed that the highest output power of FBG against honey solution B was in the range of 213.60 – 214.58 mW. Changes in Bragg wavelength were quite significant for the increase in temperature of honey solution with a difference of 0.58 – 0.76 nm.

Abstract

Optical fiber is a medium that spreads information in the form of light waves. The quality of the optical fiber can be determined by knowing the dispersion value of the polarization mode which is one of the characteristics of the optical fiber by using a single-mode optical fiber design simulation method using the OptiFiber software. The single-mode optical fibers used in the simulation are SMF-28, SMF-28e, SMF-28e+, SMF-28e+ LL, SMF-28 ULL. A good quality SMF for long-distance communication is an SMF that has a small PMD value.

Abstract

WiFi signal is an electromagnetic wave that in its transmission does not require an intermediary medium used in communication. However, signal intensity can be affected by the medium through which it travels, as is the case in the workplace. So the WiFi signal no longer provides the same strong intensity. Therefore, it is necessary to research how to determine the area with the most effective WiFi signal intensity due to fluctuating signal propagation in a closed workspace. This research is conducted by showing the source point of the router and receiver that will be used as a trip to the position function, then measurements will be made on the WiFi signal depending on the change in position. In addition, the influence of temperature and humidity in the room is also related. The results showed that the highest WiFi signal intensity was at a distance of 0.5 m from the router with a power loss of -47 dBm. While the value of the lowest WiFi signal intensity is in the range of 3 m with a power loss of -25 dBm.

Abstract

In the complex, mature, and large oilfields, there is a need for Integrated solution in order to have a helicopter view of entire facilities throughput. The real time metering information provides an on-demand daily data and trend. However, it is rarely being connected to analytics solution for business intelligence such as, prediction, optimization, decision support and forecast. This paper cover about exploratory data analysis of large dataset of multiple hydrocarbon facilities metering within integrated network, performing multi-feature data clustering and making a time-series forecasting techniques. K-means and PCA are combined to make cluster of production facilities which resulted with gas processing cluster, high oil producer, high water processing station, and the lowest performer in term in hydrocarbon processing. Furthermore, VAR and LSTM are compared as forecasting tools for day-to-day fluid prediction, to maintain normal operational scenario.

Abstract

Although many manifold shapes have been studied, research on venturi-shaped manifolds with holes smaller than the inner diameter of the pipe, hereinafter referred to as T-reducer, has so far not been found. This research studies the effect of hole diameter and Reynolds number on the debit that comes out of the branch pipe. The venturi hole diameter is varied from 40% to 80% of the main pipe diameter, while the bulk velocity is varied from 2 to 10 m/s. The research started by creating a 3D T-reducer model, followed by CFD simulation using Fluent software. From the simulation results, curve fitting is performed using multiple regression to obtain an equation which is the correlation of dimensionless numbers. The maximum difference between the flow coefficient obtained from the curve fitting equation and the CFD simulation results is 3.35%.
