Abstract

This study discusses the measurement of partial discharge in air insulation. Partial Discharge measurement is very important to know the condition of electrical equipment. Partial discharge causes are not only old equipment, but also from set-up errors and insulation problems. In this research, partial discharge measurement is using non-electric method. The non-electric method uses a loop antenna sensor that detects electromagnetic waves generated by partial discharge. Modeling the occurrence of partial discharge with a needle-plate electrode at a distance of 1 cm with air insulation. Partial discharge measurement parameters include Background Noise (BGN) measurements, Partial Discharge Inception Voltage (PDIV) and Partial Discharge Waveforms. The different parameters of each discharge were analyzed based on the given voltage level. The resulting data is a discharge wave obtained from an oscilloscope. The resulting data is processed using origin software so that it can determine the characteristics of the amplitude, duration of rise time and fall time of the discharge that occurs. From the results, it is known that the amplitude and duration of the rise time and fall time is greater at discharge with a higher voltage. The discharge characteristics depend on the applied voltage.

Abstract

The absence of selection of exemplary employees at the Ministry of Religion of Deli Serdang Regency has caused the performance and performance of employees to decline Decision support systems are interactive information systems that provide information, model and manipulate data. The decision support system for selecting exemplary employees is not used as a substitute for decisions, but as a support for decision making. The criteria set by the company in applying for credit are discipline, work performance, commitment, responsibility and quality of performance. With the AHP method, from the criteria determined the intensity of importance/priority scale on the criteria. After performing the calculation process, the decision to select exemplary employees was obtained from the ranking of the AHP method: 0.2669947 (rank 1), 0.25695721 (rank 2), 0.2446883 (rank 3), 0.229045 (rank 4). Keywords: motorcycle loan, SPK, AHP method

Abstract

PT. Indako Trading Coy is a company engaged in the sale of motorcycles and spare parts with 1000 employees who are given work targets every month. Through the targets given, it can be predicted whether employees can be rewarded or not. Prediction is an important tool in determining everything to be effective and efficient. So far, a lot of forecasting is done intuitively using statistical methods. The choice of the method depends on various influencing aspects, namely aspects of time, data patterns, type of system model being observed, level of forecast accuracy or desired prediction and so on. The forecasting method used is using an artificial neural network (ANN) with the Backpropagation method.

Abstract

Gastritis, dispepsia, tukak lambung, gastroparesis,dan penyakit refluks gastroesofageal (GERD) adalah kondisi yang berhubungan dengan lambung. Gastritis dapat terjadi setelah operasi, infeksi parah, cedera traumatis, atau luka bakar. Stres, refluks empedu, dan infeksi bakteri Heliobacter pylori semuanya merupakan penyebab kronis. Gastroparesis ialah Penyakit yang memperlambat pencernaan makanan di lambung.Bila otot-otot di dinding lambung tidak bekerja dengan baik, terjadi disfungsi lambung. Sekresi asam lambung (asam klorida) yang berlebihan menyebabkan peradangan pada dinding lambung yang disebut juga dengan tukak lambung. dispepsia adalah sekelompok gejala yang meliputi nyeri, rasa tidak nyaman pada epigastrium, mual, muntah, kembung, rasa penuh atau cepat kenyang, dan sering bersendawa. Banyak orang yang tidak memahami akan hal ini, sehingga banyak terlena dan malas untuk memeriksakan diri ke rumah sakit. Dengan demikian dirancang suatu sistem pakar yang dapat menganalisa gejala-gejala penyakit menjadi sebuah keputusan nama penyakit dengan menggunakan metode certainty factor. Metodologi yang digunakan dalam menyelesaikan Sistem Pakar Diagnosa Penyakit Lambung menggunakan metode Certainty Factor Berbasis Website yaitu metode pengumpulan data, metode wawancara, metode konsultasi dan metode pengembangan perangkat lunak. Dari pnelitian ini di hasilkan suatu sistem pakar yang dapat menganalisa gejala-gejala penyakit menjadi sebuah keputusan nama penyakit. Dengan adanya sistem pakar ini, berbagai macam informasi mengenai jenis-jenis penyakit pada lambung dapat diperoleh kapan saja dan dimana saja.
