Abstract

A  research has been conducted  to  determine  the electrical properties  of water  in  an aluminum and  iron  containers.  The  waters  used  were  well  and  rain  water using  metaland  aluminum  containers.  This research was conducted  using  an experimental method. The results showed  that  the  best  electrical properties  was  found from  rain  water  in the aluminium  container  with its  resistivity  of  18.294m ,  electrical  power  of  0.00046  W, electrical energy  of  2,941  J  and  electrical  conductivity  of  0.055  (1)m.  The  resultsindicated  that  greater  solar radiation  in  the  water  could  produce  of  electrical properties greater  than  that  of water  on  the electrical  properties of  the electrical  resistivity.The affecting factor of electrical  properties of  the rain  water  was  concentration  of  Fe  and  Cu. The  concentrations  of  Fe  and  Cu  in  rain  water  was  0,065  ppm  and  0,050  ppm.  It was also found that  the smaller  the  concentrations of  Fe  and  Cu  levels  in  solution  was  the purer the solution.

Abstract

A research has been done on physical analysis of clean water treatment at PDAM Tirta Siak Pekanbaru. The methods that used in this research was an experimental in order to analyze water treatment system, water debit which was distributed in the main pipe, and water velocity in the pipe. Raw water used in the water treatment plant uses water from the Siak River using intake. Intake on this water treatment uses two pumps with capacity of 140 liters / sec are used interchangeably to collect water. Raw water treated by coagulation, flocculation, sedimentation, filtration, and disinfection. Incoming raw water to be processed and distributed to the reservoir as the water ready to be distributed to consumers. Reservoir water discharge was obtained for 110 liters / sec or 410.4 m3/sec. Obtained debit water out of the water volume ratio of a specific time range that depends on the size of the pressure in the pipe. Based on the results of the average debit coming out in May 2014 at 9:00 to 10:00, 10:00 to 11:00, 11:00 to 12:00, 12:00 to 13:00, 13:00 to 14:00, 14:00 to 15:00 is 475,142 m3/sec, 443,594 m3/sec, 426,883 m3/sec, 431.755 m3/sec, 430.432 m3/sec, and 425.980 m3/sec, respectively. Water flow rate obtained 0.604 m/s, 0.610 m/s, 0.605 m/s, 0.612 m/s, 0.629 m/s, and 0.673 m/s, respectively.

Abstract

A research has been done in analyzing an acoustic wave and its effect to casing pressure and gas flow at annulus in order to determine liquid level depth of oil well. The research used an  experiment method  using  sonolog  type  remote fire gas gun  with  its  sound wave frequency  between  30 Hz  –  60 Hz.  Data were  taken from three oil wells that are managed  by  the  Unit of business Pertamina EP Lirik. Each  well was measured  five times  at different time.  The  data obtained were analyzed  by  Total Well Management (TWM) software. They were acoustic velocity, casing pressure, and gas flow. The value of acoustic velocity  shown by  TWM  sometimes  didn’t match to the  real condition including the data of  determined  liquid level depth.  New value of  acoustic  velocity had been gotten  using  multiple regression linear  equation. Time  travel  of  wave  was measured using Down Hole Marker  at TWM.  Result of calculation of  acoustic velocity based on  measured data  for well LS-031 at November 24th 2011 was 397,7138 m/s,  for well LS-105 measured at March 13th 2010 was 359,6792 m/s, for well LS-105 measured at November 25th was 356,17 m/s. Results  of calculation  of liquid level depth for well LS-031 was 249,9634 m, for well LS-105  was 261,23 m,  and  for well LS-097 was 246,96 m.

Abstract

A research has  been done on  the determination of the electrical conductivity and  water quality  of Siak River water  using a Wheatstone bridge method  in   the  location around the rubber factory   of PT. RICRY. The research was begun by taking samples  of the Siak river water were taken on  five  points  which  have been determined at a distance of 10 meters from PT. RICRY when was low  and high  tide. Based on the  length  data  of wire L1  and L1,  it  could  be determined  the value of electrical resistance, resistivity  and electrical conductivity. The result showed that the value of  highest  electrical conductivity of the river  water  when the  sea  water was  at  high tide  was  58,513  .  10-6 (Ωm)-1, while the electrical conductivity of  the river  water at low tide  was 41,879  . 10-6 (Ωm)-1. A decent water for consumption has an  electrical conductivity of (300  -500).106(Ωm)-1(Mailinda, U. 2011). Based on  that  standard  electrical conductivity, Siak river  water  in  the  research location when the sea water  high tide and low tide are not worthy to be consumed because  of  too small  value  compared  to  the standard   value of electrical conductivity .

Abstract

A research has been conducted on designing of an automatic experiment ofmoment of inertia using a self-timer with a variation in radius of a cylinder as an inertialbody. This research was done using an experimental method and especially to design aself-timer calculation tools used in the experiment. The trial results showed that at 0.10m height average time for a cylinder rolling on an inclined plane with a slope of 2.87°for 2 m length could be represented by the regression equation that is y = 0.031x +0.400. Based on the result of the experiment, the coefficient of the moment of inertiaranged from 0.509 to 0.523 with a percentage error ranged from 1.800% to 4.600% andstandard deviation of experimental time measured from 0.011 to 0.034 seconds.
