<p><em>The demand for electric power increases along with the development of technological progress and development. The use of electricity is an important factor in people's lives, both in households, lighting, communication, </em><em>and </em><em>industrial. The purpose of this research is to calculate the frequency response before load shedding, to calculate the frequency response after load shedding and to analyze the load recovery after normal frequency in the load. The methods to be used in writing and discussing this research are: Observation Method, Interview Method / Interview, Literature Study Method. Based on the calculation of the data in the previous chapter, the following conclusions can be drawn, the calculation of the conditions before carrying out the load shedding is based on the rate of decreasing frequency from the result obtained is 1.6 Hz / s, then to calculate the time used in determining the frequency at the time of load shedding then the results obtained are 54 Hz, Meanwhile, to calculate the frequency after load shedding that is obtained is 49.1 Hz, Calculation of load shedding time is expected when there is a decrease in frequency of 10.5 seconds, Calculation of the load rate of increase expected after load shedding then the optimal load value that must be removed is 5.55 w.  </em></p>

<p class="JOURNALBODY"><em>The development of electric vehicles is in rapid progress, especially in terms of the main engine drive. The use of solenoid can be applied as an alternative driving electric vehicles instead of a dc motor as the main driver. In this paper, the prototype solenoid machine is applied by using 4 inductors controlled by an Arduino microcontroller and the solenoid driver based on application of Mosfet L298N. The prototype runs successfully. Based on the experimental results, the greater the frequency value applies to the driver, the faster the solenoid moves. The acceleration occures due to the electromagnetic field which is getting stronger and the field is proportional to the frequency value, so the solenoid movement is faster.</em></p>

80% of cases of building or house fires in Indonesia are caused by electrical short circuits. Currently, there are only MCB and ELCB devices protecting for building electrical installations, but these devices cannot protect the conditions that cause fires. In a short circuit, there will be heating of the short cable or device. In this study, researchers used a thermal camera that can be placed on an electrical panel to be able monitor the temperature of electrical panel which includes cables, MCB, or can be placed on other devices. When the detected object temperature exceeds a predetermined limit, the device will provide a warning in the form of sound and text and can automatically cut off electricity in the building's electricity network. This research produces a prototype of a power grid safety device using a Raspberry Pi that can be applied to buildings and objects that have the potential to emit excess heat that can cause fires. Systems it will be able to monitor, provide warnings and can automatically cut off the electricity network when the temperature of the observed object exceeds the specified limit and has the potential to emit excess heat which can cause a fire.

Pandemi covid19 sekarang ini menuntun semua elemen masyarakat, termasuk elemen pendidikan wajib berdamai dan menyesuaikan diri dengan protocol kesehatan. kesehatan masyarakat dan peserta didik harus diutamakan dalam segala hal sehingga pemerintah Indonesia menerapkan work from home dan untuk layanan pendidikan menerapkan pembelajaran dalam jaringan. Hal tersebut berlaku juga pada layanan bimbingan konseling (BK), oleh sebab itu metode e-counseling akan membawa dampak dalam pemberian layanan dan bimbingan ke peserta didik. Oleh karena itu kami bermitra dengan SMA Neg. 1 Campalagian mengadakan pelatihan e-counseling dengan tujuan agar konselin tetap dapat terlaksana meskipun jarak jauh.

Leadership style is one of the factors of employee performance so that a good leadership style will be able to direct and give instructions to the work faced by employees. A good leadership style will also lead to job satisfaction for them, so they will work with feelings of pleasure and joy. Simultaneously, the Transformational Leadership Variable has a significant effect on Employee Performance with a value of Fcount > from Ftable. The result of the Coefficient of Determination (Adjusted R Square) is 0.165, meaning that the Employee Performance variable can be explained by the Transformational Leadership variable and the Meaning in Work variable by 16.5% while the remaining 83.5% is influenced by other variables.

PT XYZ is a computer shop engaged in the sale of laptops, computers, spare parts, accessories supporting and providing repair services. The marketing process is less than optimal because it only sells by phone or social media. There are some problems that occur between them : (1) Stock management is not optimal because of frequent discrepancies between stock records with the amount of goods available so often consumers feel disappointed with the services provided, (2) The issue of uploaded ad duration in uploaded social media will alternate from one product content display to another in a relatively short period of time, (3) The absence of management of consumer sales transactions thus requiring recording of repeated transactions, (4) The decline in sales turnover in recent months (5). The management of customer or consumer data is less noticed. Based on these problems, this study aims to design a web-based online sales information system mobile on PT XYZ . This research uses the development of SDLC waterfall model system which consists of planning, analysis, design, implementation and maintenance.
