  • Metaheuristic algorithms in optimization and its application: a review

    • Authors: Shahab Wahhab Kareem, kurdistan Wns Hama Ali, shavan askar, farah sami Xoshaba, roojwan hawezi
      Abstract: Metaheuristic algorithms are computational intelligence paradigms especially used for solving different optimization issues.  Metaheuristics examine a collection of solutions otherwise really be wide to be thoroughly addressed or discussed in any other way. Metaheuristics can be applied to a wide range of problems because they make accurate predictions in any optimization situation. Natural processes such as the fact of evolution in Natural selection behavioral genetics, ant behaviors in genetics, swarm behaviors of certain animals, annealing in metallurgy, and others motivate metaheuristics algorithms. The big cluster search algorithm is by far the most commonly used metaheuristic algorithm. The principle behind this algorithm is that it begins with an optimal state and then uses heuristic methods from the community search algorithm to try to refine it. Many metaheuristic algorithms in diverse environments and areas are examined, compared, and described in this article. Such as Genetic Algorithm (GA), ant Colony Optimization Algorithm (ACO), Simulated Annealing (SA), Particle Swarm Optimization (PSO) algorithm, Differential Evolution (DE) algorithm and etc. Finally, show the results of each algorithm in various environments were addressed.

  • Initial Research of Renewable Energy Resources for Hybrid Microgrid
           Implementation, Using Solar and Wind; Transforming the Diesel Dependence.
           Case Study of Mamburit Island - Indonesia

    • Authors: Eric Marcos Hughes Arrocha
      Abstract: Electrical demands are growing rapidly in the world, especially in larger cities, and Indonesia is not an exception. Indonesia's average peak demand is projected to increase by 73% (reaching 43.7 GW) in 2020, by 142% (reaching 61.2 GW) in 2025, and by 205% (reaching 77.3 GW) in 2030, compared with 25.3 GW in 2010 [1]. However, the challenge of completing the growing demand in big cities reveals another huge problem, which are those small villages, communities and islands who doesn’t have access to electricity until now.Many countries apply and use the concept of Micro Grid [MG] as an effective solution, which can be defined as: the grid where each generator or load has to take part in the network management, joining in reactive power supply/voltage control, active power supply/frequency control, fault ride-through capability, and power quality control independently [5].Using an Indonesian remote Island as a real case, different renewable energy sources available will be evaluated to propose the best Micro Grid design integration system to supply electricity facility.This research will describe the principles, measurement process and general mathematical description for the application of the MG model integration.Planning to minimize the traditional electric sources of fossil dependence, the design for Mamburit Island in Sumenep-Indonesia will integrate different generation sources such as, Solar Panel System [PV/SHS] showing Daily Average Irradiation [DNI] of 5.78 kwh/ , vertical Axis Wind Turbine [VAWT] shows wind speed annual average of 8.82 m/s and energy Storage system [ESS] as a real, feasible and friendly options to complete the demand, integrated with Engine Diesel Generator [EDG] present as the actual main sources; minimizing the fossil dependence, through MG principle. Keywords— Smart Micro Grid, Micro Grid Integration, Renewable Energy.

      Abstract: The fast spread of Coronavirus (COVID-19) poses a huge risk to people all around the world. Recently, COVID-19 testing kits have been unavailable due to rise in effected people and large demand of tests. Keeping the urgency of the situation in mind, an automatic diagnosis method for early detection of COVID-19 is needed. The proposed deep learning decision support system (DSS) for COVID-19 employs MobileNet v2 Deep learning (DL) model for effective and accurate detection. Here we collected Cough auscultations through self-designed digital sensor. The primary experimental results show that the maximum accuracy for training is around 99.91%, and the maximum accuracy for validation is 98.61%, with 97.5% precision, 98.5%recall, and 98% F1-score. The Deep Learning-based model described here strives for similar performance to medical professionals and can help pulmonologist/radiologists increase their working productivity.

  • An Investigation of Insulating Paper Effect on Gas and Aging on Mineral
           Oil Transformer

    • Authors: Aulidina Dwi Nur Andriyanti, I Made Yulistya Negara, I Gusti Ngurah Satriyadi Hernanda, Daniar Fahmi
      Abstract: A transformer is an essential component in a generator, electrical equipment that works non-stop to support electricity needs. There has been a lot of thermal and electrical activity that the presence of an oil-paper insulator can suppress. The insulating ability can decrease and lead the failure due to the aging of the insulator by heating, moisture, and impurities. The aging of the paper was unavoidable, which caused the cellulose bond to break and form dissolved gases with oil, such as Carbon monoxide, Carbon dioxide, Methane, Acetylene, Ethylene, and Ethane. So, conventional dissolved gas analysis (DGA) was used to investigate further. The use of paper insulation with a certain amount affects the electrical strength of the insulator. A breakdown test on AC voltage is carried out for the following investigation. The result showed that the percentage of paper had an optimum number to get high insulator strength. By heating mineral oil for 250 hours and 500 hours, carbon monoxide and carbon dioxide are released in the different results as the DGA test. It can be concluded that cellulose paper has affected mineral oil's dissolved gas and insulator strength.

  • Data Analytics on Indonesia Industries Economic Resilience Based on
           Poverty Rate Growth During Covid-19 Pandemic

    • Authors: Adhi Dharma Wibawa, Lukas Purba Wasesa, Wridhasari Hayuningtyas
      Abstract: Covid-19 pandemic is one of the biggest challenges that each country around the world has to overcome. This pandemic has affected a lot of countries in many sectors including Indonesia. During the year 2020 when Covid-19 cases rise in Indonesia, the poverty rate has also increased by 0.97% meaning almost 270.000 people went poor. Understanding the impact and the resilience especially on the primary industry during the Covid-19 situation is important to decrease the poverty rate as well as create new alternative strategies for the government to overcome. However, the economic resilience of primary industries such as fishing and plantation is still less to explore. In this study, the economic resilience of four major industries in Indonesia when facing the Covid-19 pandemic is presented namely tourism, fishery, plantation, and micro and small business. Bivariate correlation analysis is applied to calculate the statistical correlation between the growth of poverty rate during the Covid-19 pandemic with four major industries in 34 provinces. Based on the result, it can be concluded that plantation industries are the most resilient industries while facing the Covid-19 pandemic, so the provinces with plantation industries as their main industry are less likely to have major growth in poverty rate compared to other provinces with fewer plantation industries. The second most resilient industry is fishing. Meanwhile, the tourism industry is the most vulnerable during the pandemic situation. In this study, the qualitative analysis especially in Riau and Bali provinces is also presented.
