Abstract

Resiko terjadinya penurunan kualitas daya listrik dapat terjadi pada banyak tahapan yaitu, produksi, transformasi, distribusi, dan konsumsi energi. Salah satu cara untuk menangani masalah kualitas daya adalah dengan melakukan deteksi dan klasifikasi gangguan kualitas daya atau dalam istilah asing disebut Power Quality Disturbances (PQDs). Namun, penelitian sebelumnya hanya berfokus pada topik berikut: gangguan kebisingan (noise), kegagalan model dalam menggeneralisasi data (overfitting), dan waktu yang diperlukan untuk pelatihan dataset. Sebuah strategi baru disarankan untuk mengatasi masalah ini dengan menggabungkan kompresi dataset sinyal 1-Dimensi dengan algoritma klasifikasi convolutional neural network (CNN). Dua jenis algoritma kompresi yang diusulkan untuk dievaluasi adalah wavelet transform (WT) dan autoencoder. Data yang digunakan untuk evaluasi adalah kumpulan data sintetik menurut standar IEEE-1159, yaitu empat belas tipe PQDs yang berbeda. Selanjutnya, prosedur klasifikasi PQDs akan mengintegrasikan data terkompresi dengan algoritma klasifikasi CNN. Hasil akhir penelitian memperlihatkan, metode yang disarankan menunjukkan bahwa menggabungkan algoritma kompresi autoencoder dan metode klasifikasi CNN dapat mengenali PQDs secara efisien. Bahkan di lingkungan dengan tingkat noise 20db, pemrosesan sinyal PQDs mencapai akurasi hingga 97,14 persen dan berhasil memperkecil overfitting.

Abstract

ABSTRAKPoliteknik merupakan lembaga pendidikan vokasi yang memiliki kekhususan dalam intensitas konsumsi energi listrik. Bangunan gedung Politeknik Negeri Pontianak (POLNEP) menggunakan sumber energi listrik yang disuplai oleh PT. PLN (Persero) sebagai suplai utama dan merupakan konsumen TM (tegangan menengah). Dilihat dari data beban kelistrikan, prosentase beban terpasang terhadap variasi beban menunjukkan bahwa sebagian besar atau 45,76% dari keseluruhan beban kelistrikan pada kompleks bangunan gedung Politeknik Negeri Pontianak adalah beban pada peralatan praktek (laboratorium dan bengkel).Kegiatan audit energi di POLNEP dimaksudkan untuk mengetahui kondisi nyata sistem kelistrikan serta dengan melakukan langkah audit energi akan dapat diketahui profil penggunaan energi (penggunaan energi aktual gedung dan perangkatnya) serta mengetahui peluang penghematan energi yang paling tepat, tanpa mengurangi kualitas, kenyamanan dan tingkat pelayanan.Untuk mempermudah kegiatan pengumpulan dan validasi data kelistrikan gedung digunakan sensor arus (Custom Current Sensor).Hasil dari audit energi awal yang telah dilakukan, diperoleh data hasil perhitungan Intensitas Konsumsi Energi (IKE) listrik per satuan luas kotor (gross) kompleks bangunan gedung Politeknik Negeri Pontianak berdasarkan data sekunder konsumsi energi dari rekening pembayaran listrik pada tahun 2014 yaitu sebesar 63,37 kWh/m2 per tahun, tahun 2015 sebesar 62,30 kWh/m2 per tahun dan pada tahun 2016 sebesar 44,79 kWh/m2 per tahun. Angka IKE tersebut masih berada jauh dibawah batas standar (target IKE) yang ditentukan sehingga dapat dikatakan bahwa nilai IKE ini masih sangat efisien.Kata kunci: Audit Energi, Politeknik, Sensor Arus

Abstract

Solar Power Plants (PLTS) have great potential in Indonesia due to the year-round sunshine. To monitor the performance of solar panels, which are the main component of PLTS, an effective monitoring system is required. However, there are several challenges in remote monitoring of PLTS. The solution is to use a device that helps humans monitor PLTS performance and send notifications to phones or computers via the internet. One platform that can be used is Adafruit, an IoT platform that offers remote monitoring via the internet with hardware support and a broad community. The obtained data show that the measurement values of current, voltage, and power from the battery, solar panels, and inverter have relatively small deviations, with a Relative Deviation Average (RSR) of 4.4676%. The Overall Accuracy Rate, reaching 95.5324%, indicates that the system is reliable in providing accurate measurements, closely matching the expected reference values. Keywords: Monitoring System, Internet of Things (IoT), Adafruit.

Abstract

Generally, energy conservation is carried out on a building as a whole, but in this research the energy conservation is carried out dynamically based on the characteristics and the user of the room. In this research, the lux measurement has been taken at certain times. Based on the characteristics of the existing room at Polytechnic State of Pontianak, the lux measurements were taken at one of the electronics laboratory, one technician room, electrical engineering department library, one classroom for information technology students and one academic staff office. These rooms divided into three size: small, medium, and large. The data that has been taken was compared with the standard of room lighting according to the Indonesian National Standard SNI-03-6917-2000. Analysis in determining lux can be used with fuzzy logic based on room size, number of lights and electrical power. Lux can be obtained by 3 values, namely weak, medium, and strong. With fuzzy it is obtained that the value of output membership for Lux strong for library = 0.11, technician room = 0.10, and classroom IT 7 = 0.31 with the scale of 0 – 1. With 0 is the value of the minimum and 1 is the maximum value of the fuzzy membership. It can be seen between the 3 rooms that classroom It 7 is the room with better lighting, hence better lux value.

Abstract

Virtual Private Server is a private server whose entire resource is used by one user only and is not influenced by other users. The technology used by VPS is virtualization of physical server hardware which is then divided into several different resources. Called virtual because this division uses software so that in one physical server there are several VPS running. To be more extensive in terms of server control, researchers use Public IP and Dedicated IP as a distributor of VPS systems from local to public. In addition, in this VPS implementation, debian linux and ubuntu linux are used as operating systems to create a VPS server. To get the value of the VPS network performance test from the client using the parameters of the Quality of Service (QoS), namely Delay and Jitter. From the test results, the value of the VPS server resource obtained can be categorized as very good and feasible to be implemented with an average server CPU load of 2.9%, memory 71.23%, disk space 16.1%. And testing the QoS parameters (delay, jitter) also gets good performance and has a fairly low value obtained with an average delay value of 6-37.24%, jitter of 8.95-59.95%.
