The generator is a device for an important source of electrical energy, so the continuity of the generator operation must be maintained and well controlled, in controlling the grounding on the generator can use in control with software such as MATLAB and Modeling the design of the grid grounding system using LabView 2017, Determination of the grounding system for the neutral value of the generator through the distribution transformer, can be done through manual calculation. The use of many parameters considered in the calculation to obtain appropriate and measurable results there is a possibility of repeated calculations. This is very difficult and causes a large difference in calculation results. Therefore, a computer-based computing system is needed to overcome problems like this. Several papers have developed calculations of the amount of generator neutral grounding required that consider the voltage level, short circuit fault current and ground fault protection system. This paper discusses modeling and simulation in designing generator neutral grounding using LabView 2017 application. The goal is to be easier, faster and more accurate. As an implementation of modeling, data from std C62.92.2TM-2017 is used.

Konverter analog ke digital telah memainkan peranan penting karena sistem digital memiliki banyak keunggulan yang tidak dimiliki oleh sistem analog. Hal tersebut dibuktikan oleh sistem digital yang telah banyak diaplikasikan di berbagai bidang yang meliputi sistem telekomunikasi dan navigasi serta sistem kontrol. Keakuratan konverter dalam mengkonversi analog ke digital menentukan kualitas suatu sistem digital. Penelitian ini bertujuan menganalisis kinerja dua rangkaian konverter analog ke digital yang masing-masing berbasis integrated circuit (IC) ADC0804 dan IC ADC0809. Metode yang digunakan adalah metode simulasi dan metode pengukuran. Formula statistik berupa mean error dan standard deviation error (SDE) juga digunakan untuk menentukan tingkat keakuratan setiap rangkaian konverter. Jumlah sampel yang digunakan sebanyak 200 sample yang terdiri dari 100 sample hasil simulasi dan 100 sample hasil pengukuran. Berdasarkan hasil percobaan diperoleh bahwa ME dan SDE hasil simulasi rangkaian konverter berbasis IC ADC0809 adalah 0,6010 dan 0,5110. Sedangkan berdasarkan hasil pengukuran diperoleh ME 1,3010 dan standar deviasi 1,3810. Rangkaian konverter berbasis IC ADC0804 memiliki ME dan SDE masing-masing 1,5310 dan 0,6110 untuk hasil simulasi sedangkan untuk hasil pengukuran 2,3710 dan 1,4410. Nilai mean error dan standar deviasi rangkaian konverter berbasis IC ADC0809 lebih kecil baik berdasarkan hasil simulasi maupun hasil pengukuran. Berdasarkan hal tersebut dapat diketahui bahwa rangkaian konverter berbasis IC ADC0809 lebih akurat dari pada rangkaian konverter berbasis IC ADC0804.

Email is an internet facility for sending electronic mail. Although there is a webmail that provides standard security but for e-mail attachment documents when sending e-mail there are lots of eavesdropping, forgery, infiltration,and spamming so needed security of email. Authentication is identification carried out by each communicating party so sender and recipient of information trust each other. Although message authentication has been carried out, it is still possible for both parties to attack each other. This study aims to apply digital signatures in testing the integrity and authentication of document attachments email using the schnorr algorithm. SHA-1 hash function is used for verification, Results show that contents of email attachment will produce a different Message Digest if prime numbers are different, so cryptanalysts can’t solve it. Differences in Message Digest occur because different prime numbers cause differences in private keys and public keys. Private key and public key pairs are synchronous so sender and recipient are verified correctly. If there are changes or removed just one character from contents of document will result in a very significant Message Digest change. If someone changes contents of document or key, so verification process to be incorrect and recipient of information knows that document he received is no longer valid. Schnorr method is a strategy to provide document attachment security in emails that is better than security applied to standard emails

Abstract: The continuous use of an electric motor in some industries causes the electric motor to malfunction early. Such damage is generally caused by overheating. Therefore, to overcome the problem of overheating, most industries use two motors that work alternately. Both electric motors function as running and standby which are generally controlled manually by the operator or using a time delay relay (TDR). However, the control of both motors by the operator is not effective because it allows human error to occur. The use of TDR is also ineffective because it does not make the temperature of the electric motor a reference in controlling the work of the two electric motors. This research aims to produce a prototype that can monitor the temperature of the electric motor in real-time and control the electric motor based on the temperature of the electric motor. The Wemos D1R2 is used as a processor to control both electric motors and transmit the temperature of the electric motor to a smartphone via the internet. The MLX90614 sensor is used as an infrared-based temperature sensor. Based on the results of testing the overall performance of the prototype, it is known that the temperature readings of the electric motor are quite accurate with mean error and standard deviation of 0.13oC and 0.15oC, respectively. The prototype is also capable of controlling both electric motors automatically and controlling a cooler via a smartphone. Keywords: Electric Motor; MLX90614; Overheating; Wemos D1R2. Abstrak: Penggunaan sebuah motor listrik secara terus menerus pada sebagian industri menyebabkan motor listrik tersebut mengalami kerusakan lebih awal. Kerusakan tersebut umumnya disebabkan oleh panas berlebih. Oleh karena itu, untuk mengatasi masalah panas berlebih tersebut maka sebagian besar industri menggunakan dua buah motor yang bekerja secara bergantian. Kedua motor listrik tersebut difungsikan sebagai running dan standby yang mana umumnya dikendalikan secara manual oleh operator atau menggunakan time delay relay (TDR). Namun, pengendalian kedua motor oleh operator tidaklah efektif karena memungkinkan terjadinya human error. Penggunaan TDR juga tidak efektif karena tidak menjadikan suhu motor listrik sebagai acuan dalam mengendalikan kerja kedua motor listrik tersebut. Penelitian ini bertujuan menghasilkan sebuah prototipe yang mampu mengawasi suhu motor listrik secara real-time dan mengendalikan motor listrik berdasarkan suhu motor listrik. Wemos D1R2 digunakan sebagai prosesor untuk mengendalikan kedua motor listrik dan mengirimkan suhu motor listrik ke smartphone melalui internet. Sensor MLX90614 digunakan sebagai sensor suhu berbasis infra merah. Berdasarkan hasil pengujian kinerja prototipe secara keseluruhan diketahui bahwa hasil pembacaan suhu motor listrik cukup akurat dengan mean error dan standar deviasi masing-masing 0,13oC dan 0,15oC. Prototipe juga mampu mengontrol kedua motor listrik secara otomatis dan mengontrol sebuah pendingin melalui smartphone. Kata kunci: Motor Listrik; MLX90614; Panas Berlebih; Wemos D1R2.

Operational forecasting of solar radiation is critical for better decision-making by solar energy system operators, due to the variability of energy resources and demand. Although the numerical weather forecasting (NWP) model can predict solar radiation variables, there are often significant errors, especially in direct normal irradiation (DNI), which are influenced by the type and concentration of aerosols and clouds. This paper presents an artificial neural network (ANN) based method to generate operational DNI forecasts using weather and aerosol forecast data from the European Center for medium-range weather forecasts (ECMWF) and Copernicus atmospheric monitoring service (CAMS) respectively. The ANN model is designed to predict weather and aerosol variables at a certain time as input, while other models use the DNI forecast improvement period before the instant forecast. The model was developed using North Sumatra location observations and obtained DNI forecasting results every 10 minutes on the first day with DNI forecasting compared to the initial forecasting which was scaled down with the R2, mean absolute error (MAE), and relative mean square error (RMSE) models were 0.6753, 151.2, and 210.2 W/m2, so that and provides good agreement with experimental data.
