Abstract

Many efforts have been made in energy efficiency in electricity generation. One way to improve the efficiency of energyuse is by conducting an analysis. Analysis meant here is the exergy analysis and exergoeconomic analysis. The conceptof this analysis, not only the quantity of energy but also the quality of energy (the second law of thermodynamics). Exergyis done by sampling Teluk Lembu gas turbine power plant capacity 21.6 MW. The aim of this study was to analyze theexergy destruction and the amount of the exergy destruction in the form of cost. The result showed that the highest exergydestruction occurred in the combustion chamber reached 21,85 MW and while gas turbine is the lowest 3,09 MW andefficiency exergetic was 22,73%. Based on the calculation, analysis of exergy can determine magnitude, location of theexergy destruction. These will make it easier to conduct optimizations to increase efficiency

Abstract

The process of distributing blood from the proper storage before transfusion requires a cooling unit that is able to maintain the temperature so that the blood can be maintained and not damaged before being transfused. To maintain the chemical and structural composition of the blood, it is done by storing it at a temperature of 2-6 °C and the distribution is carried at a temperature of 2-10 °C with a maximum transit time of 24 hours specifically for whole blood. To answer this problem, this research will test the ability of a box that is used as a container for the blood distribution process using a thermoelectric cooling system. Thermoelectric was chosen for use as a cooler in the blood carrier box because of its small shape so that it can be operated in a limited space and operates at a DC voltage of 12 Volts. Thermoelectric uses a peltier element with type TEC1-12706 with the coefficient of performance (COP) value based on the highest calculation result, namely 0.176. In testing, carried out variations in place, variations in blood temperature and cooling system conditions. which in testing according to the SOP for blood distribution, the blood carrier box is able to maintain a blood temperature of 2-4 °C. So that this initial research can conclude that this blood carrier box can be used to distribute whole blood.

Abstract

Crude oil with high pour point oil (HPPO) characteristics exhibits elevated viscosity at low temperatures, promoting the deposition of wax and asphaltenes along pipeline walls. These deposits restrict flow and can lead to partial or complete blockages, posing serious challenges to flow assurance, operational safety, and environmental sustainability. Despite extensive studies on deposition mechanisms, blockage detection methods remain fragmented, with no universally reliable or integrated solution. This study presents a systematic review combined with a bibliometric analysis of Scopus-indexed publications to map research evolution, trends, and technological advancements in blockage detection methods for crude oil pipelines. Bibliometric network mapping is applied to identify dominant research clusters and emerging themes. The review evaluates key detection techniques, including pressure wave analysis, gamma-ray inspection, computational fluid dynamics (CFD), and machine learning approaches. Reported results indicate that pressure wave methods achieve detection accuracies of around 5% with prediction errors up to 35%, while gamma-ray techniques show errors of approximately 5% with maximum deviations of 0.59 cm. CFD models effectively represent flow and deposition behavior but are limited in quantifying blockage size. Machine learning approaches demonstrate improved performance, with accuracies ranging from 80.67% to 89.96%, although their robustness depends on data quality and generalizability. The analysis highlights critical gaps, including limited accuracy under varying conditions, lack of methodological integration, and reliance on single-technique approaches that fail to capture the multi-physics nature of blockage formation. The novelty of this study lies in its integrated bibliometric–systematic synthesis linking detection performance, methodological limitations, and research trends, while proposing a hybrid framework combining physical sensing, numerical modeling, and artificial intelligence. This work provides a comprehensive reference and strategic direction for developing next-generation pipeline blockage detection systems.
