PENGATURAN KECEPATAN MOTOR INDUKSI 3 FASA MENGGUNAKAN MULTILEVEL INVERTER DENGAN METODE FUZZY LOGIC CONTROLLER
Get PDFIndonesia is one of the developing countries in the industrial sector. Many industrial equipment that utilizes an electric motor to run the system. In running the system using an electric motor, it is necessary to adjust the speed of the electric motor as needed. The 3-phase induction motor is one type of electric motor that has a strong, inexpensive, and high-efficiency construction, so it is often used in industry. However, setting the speed and torque of an induction motor is not easy to do. Setting the frequency of the induction motor voltage can be done using an inverter, therefore a single phase inverter can be used to adjust the speed of a three phase induction motor. In regulating the speed of the induction motor, a control is needed to keep the speed constant as needed. In this study, a 3-phase induction motor speed regulation system was simulated using an inverter controlled by a Fuzzy Logic Controller (FLC). Based on the research that has been done, it can be seen that the Fuzzy Logic Controller (FLC) is able to regulate the speed of a 3-phase induction motor with an error of 0.25

Get PDFSejak terbukanya ruas jalan tembus jalan Sinarmas Land lambat laun mulai menimbulkan titik kemacetan baru, seperti pada ruas jalan menuju gerbang Grand City dari arah MT Haryono. Dari hasil identifikasi awal ditemukan antrian kendaraan terjadi dari arah RS Kanujoso menuju simpang wika dan dari arah Perumahan Wika menuju simpang Grand city, antrian umumnya terjadi dalam rentang waktu yang cukup panjang khususnya dari arah Wika. Untuk itu perlu dilakukan evaluasi terhadap kondisi simpang sehingga dapat diketahui panjang antrian kendaraan yang dapat terjadi di masa yang akan datang terutama jika masa pandemi covid sudah berakhir, agar dapat direncanakan rekayasa lalu lintas untuk mengantisipasi antrian panjang di masa yang akan datang. Metode analisis yang digunakan dalam mengevaluasi kinerja simpang tidak bersinyal Grand city adalah metode Sistem Dinamik (dynamic system) dengan menggunakan alat bantu aplikasi VISSIM. Data yang dianalisis menggunakan data pengukuran langsung di lapangan yakni dengan melakukan survey volume lalu lintas, survey antrian kendaraan, serta data geometric simpang dan tata guna lahan. Berdasarkan hasil analisis diperoleh nilai tundaan 21,01 detik pada hari jumat sedangkan pada hari senin adalah 22,38 detik, menunjukkan bahwa kondisi kinerja simpang pada hari Jum’at lebih baik daripada kondisi kinerja simpang pada hari Senin dengan selisih tundaan 1,37 detik. Selain itu, panjang antrian yang terjadi pada hari Jumat lebih pendek daripada panjang antrian yang terjadi pada hari Senin yaitu 30,98 meter dan 55,04 meter dimana panjang antrian pada hari Jumat lebih pendek 24,06 meter. Sesuai dengan Pedoman Pelaksanaan Kegiatan Manajemen dan Rekayasa Lalu Lintas bahwa Simpang Grand City memiliki tingkat pelayanan C. Hal yang sama juga disampaikan Dalam American Highway Capacity Manual (AHCM) 2010 dimana tundaan sebesar 22,38 detik masih masuk dalam tingkat pelayanan C untuk simpang tidak bersinyal

Kesetaraan Gender Akuntan Akademisi Perempuan Pasca Pandemi: Tantangan atau Rintangan Keberlanjutan Karir?
Get PDFThis research was sparked from the diversity of research results regarding gender equality in the accounting profession. Many studies have concluded that equality between women and men especially in the accounting profession. On the other hand, there are also many studies that find that gender discrimination against female accountants is still rife. Based on this fact, this research expands the study of gender equality within the scope of vocational education by combining quantitative studies through measuring the perceptions or beliefs of female academic accountants using the Career Pathways Survey (CPS) and qualitative methods using phenomenological approach. The results of a survey of 50 female and an empirical study of 5 of them resulted in findings that gender equality has not been fully realized. The “voice” of female is divided into two parts: women who feel gender equality and women who experience gender discrimination. The reality arises from the organizational environment but cannot be separated from internal influences. Female academic accountants feel that feminist stereotypes are indeed “decent” to limit their career development steps. On the other hand, female academic accountants in polytechnic circles who are classified as advanced state that there is no difference in treatment between women and men

Even though Balikpapan has great fisheries potential, unfortunately, the development and utilization of fishery products in this city has not been fully optimized. One of the problems faced in Balikpapan is the low selling value of fish raw materials. Fish raw materials produced from fishermen's catches or cultivation activities are often sold at relatively low prices. This is due to the lack of post-harvest processing that converts raw raw materials into value-added culinary products. The importance of post-harvest processing in the form of culinary products to increase the added value and selling power of fishery products.Therefore, to support the role of fishermen in South Balikpapan in mastering post-harvest processing, the government, research institutions and related organizations need to provide training, education and access to the necessary technology. One of the training and mentoring activities needed by fishermen groups in South Balikpapan is post-harvest processing of fish-based culinary products such as fish nuggets and fish cake. This support in the form of targeted training and mentoring for the implementation of fish nugget and fish cake product business processes can help fishermen improve their skills, adopt better processing practices, and diversify the fishery products produced. The targeted partners are the wives of fishermen who are members of the Sepinggan Raya Village Family Welfare Empowerment (PKK). With increasing mastery of post-harvest processing by fishermen's wives, it is hoped that there will be an increase in added value and competitiveness of fishery products. This will provide greater economic benefits for fishermen, increase their income, and encourage the growth and sustainability of the fisheries sector as a whole. The stages of the Village Development Program activities consist of needs assessment, outreach, procurement, theoretical outreach, technical training and mentoring. The output of this activity is to increase partners' understanding and skills regarding culinary business management and ultimately increase the involvement of women in business activities.Keywords: processing, nugget, fish cak

Implementation of Fast Fourier Transform and Artificial Neural Network in Series Arc Fault Identification and Protection System on DC Bus Microgrid
No full textA microgrid is a cluster of electrical sources and loads that are interconnected and synchronized. Microgrid operation is typically divided into two modes, isolated or connected to the grid with a single or standalone control system. In this context, it can enhance the reliability and quality of electricity supply for connected customers. When using a microgrid system, it is important to consider the risk of series arc faults. Series arc faults are sudden bursts of flames resulting from ionization of gas between two electrode gaps. These faults can occur due to manufacturing defects, installation Errors, aging, or corrosion on conductor rods, leading to imperfect connections. Detecting series arc faults in DC microgrid system operations can be challenging using standard protective devices. Failure in the protection system can pose risks of fire, electrical shock hazards, and power loss in the DC microgrid.Therefore, a device has been designed to detect series arc faults by utilizing the fast Fourier transform method and artificial neural network, which function to analyze DC signal and make decisions when faults occur by examining the average sum of current frequency values during normal and fault conditions. In this study, the average sum of current frequency values during normal conditions was found to range from 0.35437 to 0.36906 A, while during fault conditions, it ranged from 0.21450 to 0.22793 A, with an average protection identification time of 1087 ms and an ANN output accuracy of 99.98%
