Abstract

A research about measurement of the noise level in the Hydrocracker Area Complex Unibon Reactor Unit 211 PT Pertamina RU II Dumai particularly in the area of reactor, pump, and compressorhas been done. The noise level was recorded by direct measurement using two Sound Level Meters (SLM).The noise levels were measured as a function of time and distance. The results show that the highest noise levels occurred in the compressor area that is in the range of 93.685 to 93.689 dBA. While the average noise level that occurs in the area of the reactor, pump, and compressor as a function of time from 08:00 to 15:00 generates almost the same value. But on certain days and certain hours noise levels had a significant fluctuation. These fluctuations were caused by steam leaks in the connections of pipe. The results show that the level of noise as a function of distance from the source towards to the Maintenance and Campo reactor decline with the distance. The decrease in noise levels as a function of distance shown by the slopes of the graphs for maintenance and Campo reactor are -0.9939d+80,087 dan -1,71d+88,25 respectively. This slope indicates that the decrease of noise level for Campo reactor is faster than that in maintenance. This decrease is caused by the presence of sound absorption by vegetation around the area.Keywords: noise, reactors, pumps, compressors, time, and distance.

Abstract

Telah dilakukan penelitian tentang pengaruh parameter fisis terhadap jumlah air yangmenguap di kota Pekanbaru. Metodologi yang digunakan dalam penelitian ini adalah metodestatistika regresi linier ganda. Data-data yang digunakan merupakan data sekunder yangdiperoleh dari Badan Meteorologi dan Geofisika Bandara Sultan Syarif Kasim II PekanbaruRiau. Dengan menggunakan metode statistika analisa regresi linier ganda, dapat diketahuiadanya pengaruh antara kelembaban udara, kecepatan angin dan suhu udara terhadap jumlahair yang menguap sehingga diperoleh nilai korelasi antara parameter fisis terhadap jumlah airyang menguap. Nilai korelasi ini menunjukkan hubungan yang kuat antara variabel-variabeltersebut yang diperhitungkan setiap bulan. Penguapan tertinggi tahun 2008 terjadi pada bulanOktober yaitu sebesar 4,9 mm dan penguapan terendah terjadi pada bulan juli yaitu sebesar3,9 mm dan penguapan tertinggi tahun 2009 terjadi pada bulan Maret yaitu sebesar 6,4 mmdan penguapan terendah terjadi pada bulan Februari yaitu sebesar 3,9 mm sedangkanPenguapan tertinggi tahun 2010 terjadi pada bulan Mei yaitu sebesar 6,9 mm dan penguapanterendah terjadi pada bulan Desember yaitu sebesar 3,5 mm.Keywords: Parameter Fisis, Jumlah Air, Penguapan

Abstract

This study aims to determine how much the pollution level of wells digging to the distance of wells from the coast by analyzing the values of the conductivity, salinity, pH and heavy metals such as Lead(Pb), Iron(Fe) and Manganese(Mn). The method used was purposive sampling with number of sample are 10 sample points with variation distance ± 100 m. Conductivity measurements were carried out in two ways, namely using a conductivitimeter and Wheatstone bridge. The measurement results using conductivity meter indicate that the average conductivity value of a well water sample is 125.50 - 80.04 ?S/cm while the comparison using the Wheatstone bridge method has an error percentage value of 6.12 %. The salinity has values ranged from 0.112 - 0.093 ? which is classified as fresh water. The measurement of pH values shows indications of pollution, due to water classified as acid with a pH value ranging from 3.1 - 4.1. The measurement of the value of Iron(Fe) and Manganese(Mn) does not indicate water pollution due to heavy metals with an average concentration of Iron(Fe) 0.3697 mg/l and Manganese(Mn) 0.0391 mg/l. Comparison of the salinity and conductivity values to the well distance from the coast does not show relation that correlates with seawater intrusion in Mekar Indah Vilage.

Abstract

Telah dilakukan penelitian tentang faktor-faktor fisis yang mempengaruhui akumulasi Nitrogen monoksida dan Nitrogen dioksida di udara Pekanbaru pada stasiun Kulim, Sukajadi dan Tampan dengan menggunakan metodologi interpretasi data. Pengabilan data akumulasi NO dan NO2 konsentrasi NO dan NO2 dilakukan dengan menggunakan alat Nitrogen Oksida Analyzer seri APNA 360 di Laboratorium Udara Kota Pekanbaru. Data yang diamati adalah data harian dari bulan Januari tahun 2010 sampai dengan bulan Desember tahun 2012 . Hasil penelitian menunjukkan bahwa konsentrasi NO dan NO2 tidak pernah sama di setiap bulannya. Konsentrasi terendah NO terdapat di stasiun Kulim sebesar 2,43 ?g/m3 pada tahun 2012 dan konsentrasi tertinggi terdapat di stasiun Sukajadi sebesar 55,51 ?g/m3 pada tahun 2010. Konsentrasi terendah NO2 terdapat di stasiun Tampan sebesar 3,99 ?g/m3 pada tahun 2010 dan konsentrasi tertinggi terdapat di stasiun Sukajadi sebesar 92,99 ?g/m3 pada tahun 2010. Suhu, kelembaban udara dan kecepatan angin mempengaruhi besarnya konsentrasi NO dan NO2. Suhu udara yang tinggi, kelembaban udara yang rendah serta kecepatan angin yang tinggi menyebabkan konsentrasi NO dan NO2 rendah, sedangkan suhu udara yang rendah, kelembaban udara yang tinggi dan kecepatan angin yang rendah menyebabkan konsentrasi menjadi tinggi.Kata kunci: Faktor-faktor fisis, akumulasi, suhu, kelembaban udara, kecepatan angin

Abstract

A research on the testing of concrete elasticity has been done in order to measure concrete compressive strength  using a non destructive test based on sonic wave velocity. An equipment that was used for this research was a Sonic Wave Analyzer (SOWAN). In this research, concrete samples were formed in cylindrical shape with 15 cm diameter and 30 cm length. The compressive strengths of this concrete were 19  , 23    , and 25      ( ⁄ ). After that the time delay of sonic wave was measured. The research results showed that primary and secondary sonic wave velocity, elasticity, and compressive strenght were    = 3525 m/s,    = 1950 m/s,  23240  x N/ , and  24 x    ( ⁄ )  respectively. Based on the data, it was concluded that this non destructive test based on sonic wave velocity can be used to measure the concrete compressive strength, because the values obtained were comparable to the values obtained using the Universal Testing Machine (UTM) which is a destructive test.
