http://ijaems.com/ Open Access international Journal to publish research paper en-us December 2020 This paper proposes the load shedding method with considering the ranking load importance factors. The amount of shedding power is calculated based on the Primary and Secondary adjustments to restore the system’s frequency back to allowed range. The ranking and distribution shedding power on each load bus will be prosed based on the AHP algorithm. Loads with the smaller importance factor will have priority to be shed with the larger amount of shedding power and vice versa. The experimental and simulated results will be estimated on IEEE 37- bus system, the results show that the proposed method can help the frequency restores back to nominal range and reduce damages compared to the UFLS method. http://ijaems.com/detail/load-shedding-in-power-system-considering-the-generator-control-and-ahp-algorithm/ Tung Giang Tran, Hoang Thi Trang, Trong Nghia Le, Ngoc Au Nguyen, Phu Thi Ngoc Hieu http://ijaems.com/upload_images/issue_files/1IJAEMS-11120208-Loadshedding.pdf This paper aims to analyze and describe: the existence of policies and management practices in the formation of regional regulations on development progress in the district of Tulang Bolango. The research method used is a qualitative method. Data analysis used in qualitative research is an interactive model analysis which consists of three components of analysis, namely: 1) Data Reduction; 2) Presentation of Data; 3) Verification of Data and Conclusion Images. The results of the article show that: 1) Existence of Management Policies and Practices for the Formation of Regional Regulations on Development Progress in Bone Bolango District needs to emphasize the importance of collaboration with Regional Apparatus Organizations as material for consideration in formulating Regional Regulations. Apart from that, the Regional Government must always capture the aspirations of the community regarding the formulation of regional regulation policies; 2) In the formation of regional regulations in the Regional Representative Council of Bone Bolango Regency, it must consider the aspect of the right man on the right place, in the sense that Bapemperda members must be filled with human resources who understand the process of forming Regional Regulations. http://ijaems.com/detail/the-existence-of-management-policies-and-practices-for-the-information-of-regional-regulations-on-development-progress-in-bone-bolango-regency/ Hunawa Robby, Podungge Wahab Abdul http://ijaems.com/upload_images/issue_files/2IJAEMS-11120206-TheExistence.pdf This study aims to produce an Edmodo-based e-learning development product in mathematics class V at Dr. Wahidin Sudirohusodo Primary School and to know the feasibility and effectiveness of the developed Edmodo-based e-learning media. This study uses a Research and Development (R&D) approach with ADDIE model where each stage is interconnected and in stages in producing development products. The research subjects in this study are the design, media, learning material experts, the teacher, and the students. The hypothesis proposed of this study is that the development media products on Edmodo-based e-learning are feasible and effective for use in the learning process of mathematics. The data is collected through questionnaire by research subject assessment instrument and posttest from learning outcome instrument. The feasibility of the media is obtained through the validation and testing by research subjects where the average percentage of the results of the assessment of design, media, and learning material experts is 89.3%, while the average percentage of the results of teacher and student assessments in the trial of individual and groups of students is 90.5% who fall into the “Very Appropriate” category. The product effectiveness test from the learning outcome test data on the research hypothesis test through one-party test obtained tcount > ttable (2.3798 > 1.66980), which means that students’ mathematics learning outcomes with Edmodo-based e-learning were higher than students who studied conventional truth-tested. Thus development media products on Edmodo-based e-learning are feasible and effective for use in the learning process and can improve student learning outcomes compared to conventional learning. http://ijaems.com/detail/the-development-of-edmodo-based-e-learning-in-mathematics-for-class-v-at-dr-wahidin-sudirohusodo-primary-school/ Eddy Harianto, Efendi Napitupulu, Baharuddin http://ijaems.com/upload_images/issue_files/3IJAEMS-11120205-TheDevelopment.pdf This paper proposes the load shedding method based on considering the load importance factor, primary frequency adjustment, secondary frequency adjustment and neuron network. Consideration the process of primary frequency control, secondary frequency control helps to reduce the amount of load shedding power and restore the system’s frequency to the permissible range. The amount of shedding power of each load bus is distributed based on the load importance factor. Neuron network is applied to distribute load shedding strategies in the power system at different load levels. The experimental and simulated results on the IEEE 37- bus system present the frequency can restore to allowed range and reduce the damage compared to the traditional load shedding method using under frequency relay- UFLS. http://ijaems.com/detail/load-shedding-in-power-system-using-the-ahp-algorithm-and-artificial-neural-network/ Le Thi Hong Nhung, Hoang Thi Trang, Trong Nghia Le, Huy Anh Quyen, Trieu Tan Phung http://ijaems.com/upload_images/issue_files/4IJAEMS-11220201-Loadshedding.pdf In the recent times several studies and research have been conducted on drug delivery system through mouth in order to overcome several problems like emptying time and gastric retention. Taking medication through mouth is the preferable way compared to others, because of easiness in taking medication and compliance of patients. Limited gastric residence time is the limitation of taking medication orally. In order to increase this gastric retention time, several methods have been proposed. This article focuses on floating drug delivery system to overcome the difficulties associated with design of formulation. Advances and highlights of the floating raft system has been reviewed in this article. Formulation, mechanism, and development of raft forming system is also reviewed in this article. http://ijaems.com/detail/raft-forming-system-gastroretentive-drug-delivery-system/ Rohith Patel, Geethika Vaishnav http://ijaems.com/upload_images/issue_files/5IJAEMS-112202011-RaftForming.pdf Twin roll casting process is able to produce a strip from molten metal directly. Thus this process has a possibility to reduce total cost of sheet making comparing to conventional rolling process. Strip casting process has some disadvantages. Casting speed depends on the material properties. It is difficult to determine the casting conditions. Twin roll casting of aluminum alloy AC7A using commercial scale machine was operated. The aims of this study is to investigate the effect of the roll speed. Continuous strip could not be produced at the roll speed 5 m/min. Continuous strip could be produced at the roll speed 10 m/min. However, cracks were observed. Continuous strip could be produced at the roll speed 20 m/min. However, cracks were observed too. http://ijaems.com/detail/twin-roll-casting-of-aluminum-alloy-ac7a-using-commercial-scale-machine/ Makoto Hagiwara, Shinichi Nishida, Daichi Uematsu, Shogo Imai, Mizuki Kawawa, Kyohei Ogawa, Takahiro Shiga, Toshio Haga http://ijaems.com/upload_images/issue_files/6IJAEMS-11220203-TwinRoll.pdf The increasing environmental pollution caused by fossil fuel emissions from vehicles using internal combustion engines has spurred the development of electric vehicles. The power sources for the electric vehicles to operate are often stored in different types of batteries with different charging requirements. Most batteries are charged from the grid sources through AC/DC converters for charging battery packs. An effective charging system usually consists of a rectifier and a dual-active bridge (DAB). A typical controller consists of the control of DC bus, PFC (power factor correction), constant voltage (CV), and constant current (CC) for the battery. However, most conventional chargers only regulate the voltage or current of the battery when charging. These types are mainly suitable for lead acid types and the power factor correction has not been considered. Meanwhile, new generation battery packs as lithium-ion batteries require charge of CC at first. When the battery charging voltage reaches a certain voltage threshold, then switch to the mode of CV charge. Basing on the analysis of the battery charging requirements of electric vehicles, this paper presents a battery charger control solution with capability of CC and CV control as well as high power factor. The simulation results on MATLAB/Simulink have validated the effectiveness of the presented method. http://ijaems.com/detail/control-of-battery-charger-for-electric-vehicles/ Quang-Tho Tran, Vinh-Quan Nguyen, Chi-Nhan Nguyen, Van-Hien Truong http://ijaems.com/upload_images/issue_files/7IJAEMS-11220208-Controlof.pdf Due to its role in fulfilling the community’s need for nutrition and a strategic economic commodity, beef is considered pivotal. The early system of beef commodity distribution obliges manufacturers to process beef in several stages, starting from beef cattle farmers to retail beef traders, beforeit reaches consumers. Such a long beef supply chain is allegedly one of the causes which bring about its expensive price, especially during the COVID-19 pandemic. Accordingly, this research aims to collate a beef supply chain strategy during the COVID-19 Pandemic. This research was conducted in GorontaloIndonesia in June-August 2020. Sampling was done using the snowball sampling technique, from the farmers, traders, and butchers. Data analyzed in this research were primary and secondary. The data analysis used was the SWOT analysis. Our findings led us to formulate four beef supply chain strategies, i.e., 1) SO strategy: developing beef cattle breeding centers, delivering technical guidance and intensive socialization to farmers, developing reliable and sustainable institutional partnerships, and socializing agricultural waste-based food processing technology to farmers; 2) WO strategy: exerting the government’s supports, i.e., equipment, capital, fodders, breeds, vitamins, storage equipment, and drugs for cattle and farmers, orienting the management system to semi-intensive and intensive patterns through a crop-livestock integration system), socializing a marketing information system to farmers, and using information properly; 3) ST strategy: protecting domestic markets, overcoming reproductive diseases and maintaining cattle health, and socializing digital marketing and product diversification; and 4) WT strategy: developing agribusiness markets and market operation, granting business credits to traders, and complying with the government regulation on the standard price for the sale of beef cattle and beef. http://ijaems.com/detail/food-supply-chain-strategies-during-the-covid-19-pandemic/ Ria Indriani, Supriyo Imran http://ijaems.com/upload_images/issue_files/8IJAEMS-11220202-FoodSupply.pdf This research is a package that was carried out in a period of 3 years to develop a learning model based on the framework of Indonesia's national qualifications in an effort to improve students' vocational high school soft skills. The first year conducted two years ago, a draft learning model was found, namely the OSGIPE model. In the second year, a formative evaluation was carried out on the OSGIPE model through one on one, small group, and limited field trials. There was a significant increase in students' soft skills amounting to 23.05%. In the third year which is this year, a summative evaluation through wide field trials it have been carried out and still show that there is a significant increase in students' soft skills amounting to 23.44 %. It means that the OSGIPE model was feasible and effectively used to improve the soft skills of vocational high school technology students. So, the OSGIPE model can be used as an operational product concistently. http://ijaems.com/detail/the-effect-of-the-osgipe-learning-model-based-on-the-indonesian-national-qualification-framework-on-soft-skills-of-vocational-high-school-technology-students/ Julaga Situmorang, Siman, Yuniarto Mudjisusatyo http://ijaems.com/upload_images/issue_files/9IJAEMS-11120209-Theeffect.pdf Studies show that the application of Production Planning and Control (PCP) in micro and small companies, mainly in the service sector, encounters many resistance from companies. This work explored this finding by conducting a study in a hotel located in the Metropolitan Region of the Paraíba Valley and North Coast located in the Sao Paulo State , Brazil, with the aim of detailing the situation from the perspective of Production Engineering. The methodology of the bibliographic research in periodicals on the application of the PCP in micro and small companies, in the area of services and in the hotel sector was used, and the results confirmed the possibility of improvements for the sector, contributing to a more rational management of resources and an increase in the reliability of the services provided by the enterprise. http://ijaems.com/detail/production-planning-and-control-improvement-proposal-for-the-stock-management-of-a-hotel-located-in-a-brazilian-metropolitan-region/ Cleginaldo Pereira de Carvalho, Andreia Cristina Ribeiro Silva http://ijaems.com/upload_images/issue_files/10IJAEMS-11220209-Production.pdf This study described the challenges encountered by the 100 selected parents in the education of their children, enrolled at the primary level, during the COVID-19 Pandemic.

The present research work is to demonstrate the state of the art on Six Sigma and the perspectives in several industries through a bibliometric analysis using Bibliometrix. A database from Scopus is used, which includes a total of 857 articles in a time span from 2016 to 2020. From the results obtained, some characteristics of the articles are illustrated and analyzed (keywords, main authors, country of origin, main journals, scientific production and collaborative networks). The results obtained from the analysis show the existence of an exponential increase trend on Six sigma, being the basis for improving the quality of the processes. http://ijaems.com/detail/six-sigma-and-the-application-perspectives-of-various-industries-a-bibliometric-analysis/ Kevin Luis Mendoza-Loyo, Sergio Vázquez-Rosas, Emma Isabel Caballero-López, Uriel Alejandro Hernández-Sánchez http://ijaems.com/upload_images/issue_files/12IJAEMS-11220206-SixSigma.pdf This research paper deals with an outlier which is known as an unusual behavior of any substance present in the spot. This is a detection process that can be employed for both anomaly detection and abnormal observation. This can be obtained through other members who belong to that data set. The deviation present in the outlier process can be attained by measuring certain terms like range, size, activity, etc. By detecting outlier one can easily reject the negativity present in the field. For instance, in healthcare, the health condition of a person can be determined through his latest health report or his regular activity. When found the person being inactive there may be a chance for that person to be sick. Many approaches have been used in this research paper for detecting outliers. The approaches used in this research are 1) Centroid based approach based on K-Means and Hierarchical Clustering algorithm and 2) through Clustering based approach. This approach may help in detecting outlier by grouping all similar elements in the same group. For grouping, the elements clustering method paves a way for it. This research paper will be based on the above mentioned 2 approaches. http://ijaems.com/detail/an-analysis-of-outlier-detection-through-clustering-method/ T. Chandrakala, S.

Composite deck slabs consist of profile deck sheet and concrete. Several researchers have been studying the behaviour of composite slab but due to its complex behaviour yet it is not completely understood. The behaviour of composite slab directly depends on the deformability and contact strength. Here, some important literature reviews regarding composite slab behavior incorporating different profiles were discussed. http://ijaems.com/detail/review-on-the-effect-of-shear-connectors-on-composite-deck-slabs/ Tarek Ali, Sameh Yehia, Mohamed El-Didamouny http://ijaems.com/upload_images/issue_files/14IJAEMS-112202010-Reviewon.pdf Five to six thousand-year before Christ, gardening was in vogue. The importance of gardening is realized by every individual now in the globe. Gardening which was only an art and science in the earlier days has now emerged as a huge industry. With the importance and need of gardening in improving and conserving the environment being strongly felt now, the concept of landscaping and gardening is growing rapidly. Ornamental gardening and landscaping have expanded as a multi-faceted industry encompassing activities such as propagating and rearing ornamental plants, landscaping, production of growing media, pots and other accessories, generating huge employment opportunities and simultaneously promoting activities that would improve the environment (eagri.org). Farming has become the primary source of livelihood for Novo Ecijanos (N.Natividad, 2020) but due to a growing and phenomenal flourishing of gardening business in Cabanatuan City, Nueva Ecija, Philippines, the researchers want to investigate the entrepreneurial strategies used by the owners as the respondents to survive their business and be on the top. This study used a descriptive method of research which is very helpful in interpreting the gathered data in a survey questionnaire answered by 13 selected gardening business owners in the City of Cabanatuan. It was concluded that there are some entrepreneurial strategies often used by the business and some strategies were rarely done by them, that is why pertinent recommendations for the benefit of the business were given by the researchers at the end of the study. http://ijaems.com/detail/entrepreneurial-strategies-of-gardening-business-in-cabanatuan-city-philippines/ Alvin Gino M.
