Abstract

Every day fenomena at Tuanku Tambusai Street (Kumu), there some public transport still take or drop passanger at the unsafe place, that, while the road capasity is decrease, this can be disturbing the other vehycle that trought that road. Beside that the survey at buzy road, there are shop, campus and other lokation that can create high traffic rise and pull. To solve this problem, have to analize the condition of the road now and 5 year later, is the road capacity still under the alowed tolerance or it’s execceded.This research used Survey Method, that put some surveyor at road that want to survey to count vehicle that trought the road in 1 hour, with 5 minuttes interval. From the data obtained and analyzed primarily related to the performance of the road on existing condition and the next 5 years.From the analysis, where the value of the degree of saturation at 0.24 which is still far from the value of tolerance limits required by MKJI 1997. So for the current conditions of road are still able to accommodate traffic flow that occurs.

Abstract

Solidification of molten metal in squeeze casting was done under high pressure condition, it’s will produces small grains. Grains size, thickness and density depend on silicon content, molding and pouring temperature of squeeze cast parameters. The aim of this research is to analize silicon content, melt and mold temperature on thickness and density of to get a high caracteristicfhisicof thin wall squeeze castof Al-SiHydraulic pressure of 135 MPa is applied to forge molten metal of aluminum-silicon alloys. Mold temperature from 220 to 3300C, pouring temperature from 665 to 8850C and silicon content from 0,45 to 6,04% weight were considered. Thickness and density were used to indicate the caracteristic fhisic of thin wall squeeze castof Al-Si. Vernier caliper was used toruleofdimension of thin wall.The increasing of silicon content decreases thickness andincreases density of thin wall. The increasing of pouring and mold temperature increases density and decreases thickness of thin wall. Combination of the higher silicon content, melt and mold temperature produced a lowest thickness, high density and flawless thin wall squeeze cast of hot crack

Abstract

In this globalization, companies are have to increase productivity in order to produce maximum output. In this case, especially system productivity company. Smoothness system or production process is supported by many aspects, one of which is the aspect of reliability of existing machinery or equipment in the production system.In palm oil mills, there are two processing stations and processing of palm fruit processing palm kernel. Palm kernel oil processing systems, among others, Pressing, Nut fiber, Depricarper, Polishing drum, cyclone Nut, Nut hoper, Ripple mill, LTDS 1 & 2, Claybath. To increase the productivity of these systems need to be an appropriate activity treatment on the machine or equipment, in an effort to increase conduction reliability of the equipment in the system kernel oil processing. For it is necessary for treatment planning method RCM (Reliability Centered Maintenance) using qualitative analysis where the RCM method can determine the identification of critical equipment and components, optimum care, treatment and consequences of activity intervals failures in machinery or equipment or core processing system palm on palm oil mills company.

Abstract

Parking problem at Muara Rumbai Market is there are no special place to parking, just used the street around the market. And the consequently, visitor will park they vehicle at the street, that will constricting the street. If this not anticipate from now on, will make traffic jam at the street. To solving this problem, have to do some analysis for parking problem around the market.This research use survey method, which place some surveyor at the parking location around the market at the peak hour to recording the vehicle license plate numbers of motorcycles and passenger cars at the survey form for 4 hours with 5 minutes interval. From the data carried out, analyze how much parking accumulate, parking indexes and turn over at the parking location.From the analysis can found that the accumulate parking is passenger cars with 41 vehicles and 296 motorcycles. The low number of turn over passenger cars are couse by the most vehicle parking at this market is belong to marketeer. The turn over number of the motorcycles is 1.2 motorcycle/parking lot, this show the parking lot use by motorcycle is high enough

Abstract

The paddy chaff is a waste of paddy hulling, and it contains dominant silica which is as big as 93 % and almost has the same contain of silica that exist on micro-silica of factory brand. With its character, if it mixed into concrete mixture, it will fix the characteristic of concrete. In this research, the ash of paddy chaff is added into the mix of normal concrete, C- 225 Kg / Cm2, with the variation of the ashes chaff 0%, 2,5%, 5%, 7,5%, and 10%, heavy of percentage of the ashes, it was taken based of the weight of cement. The effect of this research is to know the pressing strong point of concrete, is reached from the chaff ash mixture paddy in concrete k 225 kg / cm.The design of concretes used the standard of SK.SNI.T-15-1990-03 that default in Indonesia. The object of the test, that is made for each one ash of percentage increase chaff is as much 3 samples, with cylinders printed of diameter is about 15 cm and tall is about 30 cm.

Abstract

The aim of this research was analyze of existing primary canal dimension at Sungai Tanang Irrigation Area, Kampar District in order courage program of Operasi Pangan Riau Makmur (OPRM) Riau Province for empowerment of rice. Method was used to analyze the water available using Mock Method by rainfall data in Pasar Kampar Station at year 1998 to 2008, and so climate data such as temperature, wind speed, humidity and sunshine. For the analyze of discharge capacity primary canal at Sungai Tanang Irrigation Area, Kampar District using Continuity Law formulation. The result of this research prove that condition of capacity discharge for existing primary canal at Sungai Tanang Irrigation area 0.09 m3/sec still have ability to the planting pattern scenario pady-pady-pady, the maximum irrigation water requirment were found on May 0.03 m3/sec.
