Abstract

Permasalahan terbesar dalam pengendalian reaktor alir tangki berpengaduk adalah sistem yang sangat tidak linear dan multivariabel. Sistem pengendalian konvensional tidak dapat mengkontrol sistem semacam ini dengan optimal, sehingga kemurnian produk yang dihasilkan rendah. Multiple Model Predictive Control (MMPC) digunakan untuk mengatasi masalah pengendalian proses yang nonlinear dan melibatkan banyak variabel. Beberapa MPC lokal digunakan pada MMPC diperoleh dengan metode yang baru dikembangkan, Representative Model Predictive Control (RMPC). Penelitian ini menggunakan model reaktor alir tangki berpengaduk yang disimulasikan dengan perangkat lunak MATLAB. Variabel yang dimanipulasi adalah suhu inlet pendingin dan konsentrasi umpan. Sedangkan variabel yang dikontrol adalah komposisi produk. Untuk perubahan set point konsentrasi produk dari 8.5 sampai 8.6; disarankan menggunakan MMPC 4,1,2.

Abstract

Vibration on End Mill Feeds will occur due to friction between the workpiece and end mill. The friction which occurs will cause tool wear in the insert blade. At this point, the tool wear experienced by the end mill can be seen from the imperfect feed of the workpiece that is resulted. Therefore, it is necessary to find out a method that can quickly and accurately detect tool wear at the end mill. The one that was experimented in this study was the vibration method. The vibration response was measured at their x, y, and z axes with rotation speeds of 2500 rpm, 3500 rpm, and 4500 rpm. At the broken end mill, it was shown that frequencies resulted did not affect the rotation while in the standard end mill. The initial frequency was highly influenced by spindle rotations treated on it.

Abstract

This study was motivated by the case of the disappearance of legal bus services due to their loss in competition with a kind of car services called “Travel” for the corridor of Padang - Pesisir Selatan, West Sumatera, Indonesia. Travel might not legal public transport services, and therefore, in this study is also called un-official public transportation. This study aims to determine the driving attributes for passenger’s satisfaction of un-official public transportation services and to figure out the service attributes that need to be improved according to passengers’ perceptions. Data was collected using random sampling with a total sample of 160 respondents and was analyzed using the Importance Satisfaction Analysis (ISA) method. Quadrant analysis of ISA revealed that the availability of music and air conditioner on-board is not so essential but resulting a higher satisfaction to passengers. Passengers are calling for an improvement of the services by consistently implementing the law against a driver who uses a mobile phone while driving or driving inconsiderately, and improving the courtesy and friendliness of the driver.

Abstract

Gangguan harmonisa yang terjadi pada sistem distribusi tenaga listrik akibat terjadinya distorsi gelombang arus dan tegangan. Distorsi gelombang arus dan tegangan ini disebabkan adanya pembentukan gelombang-gelombang dengan frekuensi kelipatan bulat dari frekuensi fundamentalnya. Gelombang-gelombang ini kemudian menumpang pada gelombang aslinya sehingga terbentuk gelombang cacat yang merupakan jumlah antara gelombang murni sesaat dengan gelombang harmonik. Keberadaan beban non-linier yang terdapat pada Kampus Politeknik Enjinering Indorama sebagai sebagian penyumbang harmonisa yang terjadi diantaranya electronic ballast, variable frequency, thyristor ac power controllers (TCR), silicon controlled rectifier (SCR), serta adjustable speed drive (ASD) yang terdapat pada unit mesin Drawn Texture Yarn (DTY). Pengukuran dilakukan untuk melihat kandungan harmonisa arus dan tegangan listrik di Panel Room yang terdapatnya alat ukur Digital Power Meter Mikro DPM 380 selama 2 (dua) hari kerja berturut-turut pada jam-jam tertentu. Sebagai perbandingan pengukuran dilakukan perbandingan dengan standar IEEE 519. 1992 sebagai evaluasi terhadap kualitas daya listrik pda Kampus Politeknik Enjinering Indorama. Hasil penelitian ini menunjukan bahwa kandungan harmonisa arus (% THDi) pada waktu  rentang 2.4 % - 4.1% untuk standar 15 % masih berada diambang diizinkan dan harmonisa tegangan  pada jam rentang (%THDv) 3.6 % - 26.6% untuk standar 5 %. Hal ini menunjukkan bahwa secara umum kandungan harmonisa tegangan pada Kampus Politeknik Enjinering Indorama berada diatas ambang batas yang di izinkan.

Abstract

Energy audit is one of the first tasks to be performed in the accomplishment of an effective energy cost control program. To obtain the best information for a successful energy audit, the auditor must make some measurements during the audit visit. One of the tools that primarily used in audit visit is the portable Power Quality Analyzers (PQA) for measuring single to three-phase lines with a high degree of precision and accuracy. It is utilized for monitoring and recording power supply anomalies. For most survey applications, changing currents makes it mandatory for data to be compiled over a period of time with enormous amount of electricity data. Hence, this paper proposed a Business Intelligence approach that can facilitate the auditor to quickly analyze the PQA data. There are five Key Performance Indicators (KPI) to be displayed for analyze in form of dashboard. The method that uses to construct the dashboard is classification and association rules with the help of orange dataminer tools. Classification method is utilized to display the data distributions by frequency on a bar chart. Once we got the frequent sets, they allow us to extract association rules among the item sets, where we make some statement about how likely are two sets of items to co-occur or to conditionally occur. The result of this paper is a dashboard of five scorecards, namely unbalanced voltage, unbalanced currents, voltage harmonic, currents harmonic, and power factor.
