Abstract

Pada operasi sistem tenaga listrik, pensuplaian tenaga listrik ke konsumen dikatakan baik apabila besarnya tegangan dan frekuensi yang diterima sesuai dengan yang ditentukan dan masih dalam batas toleransinya. Load shedding atau pelepasan beban pada penyulang dilakukan secara otomatis dengan menggunakan under frequency relay (UFR). Pada penelitian ini dibuat simulasi program komputer untuk menganalisis tahapan load shedding yang digunakan oleh PT. PLN (Persero) Sektor Barito sehingga dapat diketahui respon frekuensi akhir setelah dilakukan pelepasan beban dan selanjutnya mencoba memberikan usulan tahapan peleasan beban yang lain untuk mendapatkan respon frekuensi yang baik. Pada output dari simulasi program diperlihatkan untuk pembebanan maksimum 77,9 MW, frekuensi akhirnya adalah 50,61 Hz dan untuk pembebanan minimum 53 MW, frekuensi akhirnya sebesar 50,02 Hz dengan kondisi sistem kehilangan satu unit pembangkit (skenario pertama). Kemudian untuk kondisi sistem kehilangan dua unit pembangkit terbesarnya (skenario kedua), pada pembebanan maksimum 77,9 MW dan minimum 53 MW, frekuensi akhinya masing-masing sebesar 49,7 Hz dan 50,3 Hz.

Abstract

In some forms, energy is the basic input to life. Energy is equally important to improve the quality of life. Energy conservation can help reduce the demand for energy globally and indirectly improve the environment by reducing the use of fossil fuels. Pumps in drinking water companies are used for processing and distributing water to consumers. Variable frequency drives offer efficient control for the centrifugal pump, which can save the electrical energy required for its operation. Keywords: energy conservation, centrifugal pump, variable frequency drive

Abstract

This paper offers a solution for securing a simple residential installation of the dangers of electric shock. In the introduction, the background of the importance of using a protection system in electrical installations is explained and some definitions related to electric shock and RCBO. For the part of the research method, the specifications of the RCBO used are displayed and the flow of the research is also shown. In the discussion and the results it is known that RCBO will trif if there is an overload, short circuit, and electric shock caused by direct contact with the live part. For nominal current (In) from RCBO, RCBO with a value of 6 Ampere and its current sensitivity (I∆n = 30 mA) is chosen according to the RCBO on the market.

Abstract

At Syaichona Moh. Cholil Islamic Boarding School Gambut is one of the events where students will be selected and have the right to be made outstanding students, usually called student stars. To simplify, it is necessary to create a decision support system (DSS). In the SPK selection of outstanding students, the Simple Additive Weighting (SAW) method was used. This method can determine the weight value for each criterion, followed by a ranking process to select the best alternative from all the alternatives. The student achievement data used is data from the test score of class 4 students at the MI level graduating in 2020. In the DSS test using the SAW method, it can be concluded that the highest score with a value of 0.90 is the value recommended by the user to determine outstanding students.

Abstract

The use of information technology in the field of education aims to make educational organizations or institutions more efficient. One example of information technology in the world of education is building a school information system, one of which is the academic information system for Madrasah Aliyah Raudatul Yatama. Based on the evaluation results of improving the quality of the Raudatul Yatama Madrasah Aliyah information system, the suggestions for improvement that are the focus are the measurement aspects that direct the user interface to a simpler level but have high usability. Because more than half of the respondents stated that the user interface still needs development both in terms of appearance and usability, Therefore, the developer of the Madrasah Aliyah Raudatul Yatama information system can focus more on the aspects included in these criteria for better system quality.

Abstract

Technological developments that are increasingly advanced and developing can be utilized to support human work, including in the government sector. One form of good government can be seen from the services provided to the public which have been carried out effectively and efficiently. In the business world, the role of information technology and reliable application programs is no longer in doubt in supporting the ability of business units to win business competition. BUMDes Sinar Bulan Village has several business units that have been developed, one of which is the sale of agricultural products, because almost all of the people of Sinar Bulan Village are farmers, so agricultural products can be used as an opportunity by the village government to increase BUMDes income. In terms of recording buying and selling transactions, it is still done manually and does not comply with the rules in the accounting application program, resulting in an ineffective and inefficient recording system. Therefore, this research aims to create a Sinar Bulan village-owned enterprise (BUMDES) application program for WEB-based sales of agricultural products
