With ever-growing population, the demand of electric power is also increasing day by day. To meet this increasing demand, the power transferred should also increase. However, the existing EHV transmission lines cannot be loaded up to their thermal limits because of the considerations of their transient stability. To address this issue simultaneous power transfer scheme came into existence. With this scheme it is possible to load the transmission lines close to their thermal limits, thus increasing the power transfer capacity of the line. This is done by the transferring AC power with DC current superimposed on it. A double circuit line is converted into composite AC-DC line which will be used for simultaneous AC-DC transmission. In this work, simple mathematical model of composite line is developed and analysed to track down the conditions for maximum power transfer. Developed mathematical approach is also compared with the existing graphical method for calculating maximum power transfer. The results obtained from mathematical model are found to be in close proximity to those obtained by graphical analysis.

Data on agricultural commodities in Indonesia are provided Ministry of Agriculture, Republic of Indonesia which can be accessed on Agricultural Statistics Database at http://aplikasi.pertanian.go.id/bdsp/index.asp. The data are presented to the public in tabular formats. In order to provide the analytical tool for the agricultural commodities data, this study aims to develop a Spatial Online Analytical Processing (SOLAP) that is integrated to spatial data warehouse. The SOLAP for Agricultural Commodities adopts the three-tier architecture. The first layer is the visualization layer which is responsible for displaying data summary in tabular format, graphics, and maps. This layer consists of OpenLayers, GeoJSON, HTML and Java Script. The second layer is the logic layer which is responsible for receiving input parameters from the visualization layer, retrieving data according to parameters to the data layer, processing data, then returning the data to the visualization layer. The logic layer uses PHP as the programming language and CakePhp framework. The third layer is the data layer which is the agricultural commodities data storage. This layer consists of OLAP engine Mondrian and PostgreSQL. The SOLAP for Agricultural Commodities has successfully implemented and can provide the summary of agricultural commodities data in tabular format and maps.

This research proposes the use of Harris Corner Detector and Lucas-Kanade Tracker methods for the detection of 3D objects based on stereo image. The test image obtained from the results of capturing of the camera to the object of the form of tubes, balls, cubes, and 2D images. This research is the early step in the development of the ability of a computer vision to be able to mimic the performance of eye organs in humans in detecting an object. The detection step of the proposed method begins by determining the feature point on the image of the taking results of two cameras using the Harris Corner Detector. After the feature point of the two images obtained, then performed tracking feature point using the Lucas-Kanade Tracker method. In this research, the distance between the cameras used 10, 20, and 50 cm. The Effectiveness of the detection result of the proposed method is measured using the recall and precision parameter values obtained in the merged of the image. The proposed method gives a Recall value above 90% and a precision value above 50% for a distance of the cameras 10cm and 20cm for ball and tube objects. In the box object, the Recall value is 60% for a distance between the cameras 50cm and below 25% for a distance of the cameras 10cm and 20cm. The precision value for detection of the box object is very low, i.e. less than 25%.

There are some issues with the adoption of information technology of infrastructure library (ITIL). The common issue comes from customers that always need excellent services. On the other hand, there are employees acting as an internal element of enterprise who need to be motivated while delivering the services. It has been known that the pressure at work and employees' personal problem can cause negative impacts such as decreasing the productivity and lack of teamwork. Moreover, IT managers have a limitation in understanding the psychological issues. Hence, it drives the enterprise to adopt an approach, which can help IT managers to motivate and reward the employees. They also need to ensure the employees that enterprise can be trusted, which means they should not be any doubt in helping the enterprise to reach the goals. Gamification is one of the persuasive approaches that have been used to boost motivation. In previous research, the design of user-centric ITIL function, which embedded gamification approach has been designed. But, the design still required evaluation in order to reveal the positive correlation between the user engagement and system success. This research focused on presenting the impact of user engagement towards successful ITIL adoption.

Cuckoo search algorithm (CSA) is one of behavior algorithm which is effective to solve optimization problem including the clustering problem. Based on investigation, k-means is also effective to solve the clustering problem specially in fast convergence. This paper combines two algorithms, cuckoo search algorithm and k-means algorithm in clustering problem called FCSA. Cuckoo search is used to build the robust initialization, while K-means is used to accelerate by building the solutions. The result confirms that FCSA's computational time in ten datasets is faster than the compared algorithm.

Historical lightning data could be use to evaluate certain transmission line in power system network. By using historical data from lightning detection system with combined Magnetic Direction Finder and Time of Arrival method, lightning data mapping for West Java province was presented in this paper. According to the lightning data mapping from total recorded event, the peak current of the lightning was mostly ranged within 10 kA to 15 kA with median peak current value up to 20 kA. Bogor and Bandung had relatively high lightning density among other area within West Java province. Evaluation of lightning exposure for 150 kV transmission line on Bogor and Bandung were presented to determine which segment of the transmission line should be set as priority during routine monitoring and maintenance. Transmission fault or reclose event analysis using recorded lightning data was presented as a recommendation for further maintenance on the tower part prior to fault or reclose event, e.g., insulation string, ground wire or tower grounding.

Device-to-Device (D2D) communication has currently been emerging as a promising technology to increase capacity and to extend coverage area in cellular communication network. D2D communication allows direct communication between two or more devices such as mobile user equipments without any base station help as a relay. However, enabling D2D features in cellular communication network will reveal more complex interference problems, because D2D communication could share the same frequency resources as its underlain cellular communication network. This paper analyzes the interference problems in such D2D communications underlying cellular communication network for downlink transmission. This paper explores the use of power control methods to reduce the effect of interference. The decision whether to increase or to decrease the power level on base station (evolved Node B/eNB in Fourth Generation/4G Cellular Networks) or on the transmitter of D2D pair (Transmitter of D2D User Equipment/TUE) is based on the estimated current Signal to Interference plus Noise Ratio (SINR). First method of power control (PC-1) uses a fixed value to control the power level of the transmitter. Another one (PC-2) uses moving average of interference power values. The simulation was carried out to evaluate those two power control methods and its results in term of Cumulative Distribution Function (CDF) of SINR are compared to the system without power control method. The simulation results show that both power control methods contribute the improvement of performances; for one cellular equipment (CUE) and 100 pairs of D2D it achieved the improvement of SINR distribution at 5% with PC-1 and at 4% with PC-2 compared to the system without powr control, meanwhile for 1 D2D pair and 100 CUEs the CDF of SINR at 0 dB achieves 40%, 3%, and 0% for the systems without power control, with PC-1, and PC-2 methods, accordingly.

Rapid economic developments have forced power networks and pipeline networks to share the same pathway. Induced voltages and currents appear on pipelines running parallel with high voltage transmission line when the transmission line is hit by lightning strike. In this study, a simulation had been carried out to determine the first lightning stroke effect on an underground pipeline coating stress. CDEGS software was used to solve Maxwell equations; in particular, HIFREQ and FFTSES tools were utilized. A 2-km underground pipeline and a 345-kV transmission line (TL) tower had been modeled. A suitable TL-pipeline distance need to determined based on lightning current, surrounding soil properties, and coating withstand voltage. In addition, horizontal and vertical rods are able to reduce the overvoltage across the coating. The first layer soil resistivity and thickness are important factors to be considered when carrying out mitigation in a non-uniform soil.
