The electrical power system in existing Balikpapan Refinery is not possible to interconnect with new loads and New Power Plant. This scheme was limited by rating capacity and short circuit. In this paper has describes power system study of optimization in designing Balikpapan Refinery power plant system, through the interconnection between Existing, RDMP phase-I and RDMP phase-II with Single Power Island concept. The main problem to connecting all the power generators become single power island at 33 kV bus is resulting in short circuit rating in excess of 40 kA. In term of process design and constructability, three (3) scheme were purposed and evaluated. Selected scheme with 33 kV synchronization bus installed with the inter-tie transformer to split two groups has been analyzed to meet the minimum requirement of design criteria and power system study. Using ETAP Model with 3 (three) method of studies result that maximum short circuit has been reduced to 32.074 kA from 46.403 kA respectively. Also from this integration concept has been optimized the number of the spare generator from each island power plant become 1 (one) unit common spare generator, which lead to reducing CAPEX of overall Project RDMP phase-I and RDMP phase-II.

The smart city is a topic that has begun to capture the interest of researchers. This study aims to capture trends of smart city research in Indonesia by conducting a bibliometric analysis of the scientific publications indexed by Scopus. The number of documents published, the most cited papers, and the productivity of the smart city research community in Indonesia were analyzed. The research focuses were determined by clustering keywords using VOSviewer. The Indonesian institution most active in smart city studies was Institut Teknologi Bandung, and the most productive author was from this institution as well. Sixteen papers on this topic have been published by S.H. Supangkat. While e-government, transportation, and natural disaster mitigation were topics related to smart cities, the Internet of things and big data analysis play an essential role in smart city development.

Terahertz (THz) frequency band offers several advantages over microwave band such as larger bandwidth and radiation capability for various imaging applications. One of the important components is the THz detector applicable for room temperature use. For the lower THz frequency band, an antenna-coupled microbolometer is considered as the THz wave detector due to its compact structure and easy to fabricate. In this paper, we design and simulate the antenna-coupled microbolometer for 1 THz frequency band. Simulation is conducted by using CST Microwave Studio. A surface current analysis is performed to understand the effect of the increasing resistance of the microbolometer to the power efficiency performance. From the simulation results, the proposed design and analysis method reveals that power efficiency of the microbolometer can be increased by increasing the resistance of the microbolometer.

Indonesian customer behavior is changing along with the adoption of the Fourth Generation (4G). On the other hand, the existence of the Over-The-Top (OTT) service has replaced the Second Generation (2G) technology which has been the operator’s main income. This study analyzed the sustainability of 2G technology by collecting data including the number of the subscriber, handset capability distribution, revenue distribution, and traffic distribution from one of Mobile Network Operators (MNOs). This study observed the market share and market growth of the 2G, 3G, and 4G based on revenue and traffic distribution using the Boston Consulting Group (BCG) matrix for making technological decisions. The result showed that the 2G is classified as Dogs and has been in the decline phase of the technology life cycle. From a technical point of view, we forecasted and showed that the 2G traffic decreases following S-Curve model and remaining only 2% of the traffic in December 2019. This suggested MNO and regulator to prepare some procedures to terminate the 2G. Moreover, we proposed a strategy for the 2G termination based on busy hour traffic and spectrum re-farming that could be implemented in a cell.

Concrete structure needs an inspection to prevent structural failures. In concrete inspection activity, ground-penetrating radar (GPR) is one of the tools used to detect the location of steel reinforcement in concrete without the need for invasive action. In this paper, GPR for concrete inspection application is designed using frequency modulated continuous wave (FMCW) and works on ISM bands with a frequency range of 2.4 – 2.5 GHz. Based on radar cross section value and total loss value, a calculation is performed using the radar equation to find the total gain required by the system. The total gain value required by the GPR system with 1-meter detection capability is 11.066 dB and the total gain requirement can be fulfilled using an antenna and low noise amplifier. Meanwhile, the total gain value required by the GPR system with 3-meter detection capability is 165.79 dB. In this research the RX and TX antenna beamwidth specification was calculated. The RX antenna is expected to meet 2.86° – 48.45° beamwidth specifications for 1-meter detection capability and 0.95° – 17.6° beamwidth specifications for 3-meter detection capability. The TX antenna is expected to meet 90° – 126.87° beamwidth specifications for 1-meter and 3-meter GPR detection capability. The GPR FMCW system designed in this paper uses Lime SDR as a transceiver module.

Simultaneous measurements of several properties are important for a microfluidic system application. In this paper, electrochemical and localized surface plasmon (LSPR) sensors were integrated on an interdigital electrode (IDE) for simultaneous monitoring of impedance and refractive index of samples. First, the IDE was made and then gold nanoparticles were formed on the IDE electrodes by the thermal annealing method for the LSPR sensor. The measured results suggest that the electrical and optical properties of samples are measurable by the integrated IDE.
