The estimated cost at the initial or conceptual stage is an estimate made when there is still little information about the image, description and specifications of the work to be done. This estimate is needed to provide information on the initial description of the total construction costs. Estimated costs must be accurate so as not to cause problems in the future. To obtain a method that meets these needs, we compare two estimation methods, namely the Cost Significant Model and the Metode Parametrik. This study aims to determine the components of the calculation needed by the Cost Significant Model and Parametric Method and the comparison of the two in making cost estimates and for determining the most accurate method. This research was applied to the construction of a 2-storey building in the province of West Sumatra. Data related to the study were collected from consultants in the city of Padang with 9 (nine) RAB data complete with project information originating from 2013 s.d. 2016Based on the Cost Significant Model analysis, the regression analysis formula is obtained: Y = 1,340,187,179 + 3,175 X2 + 0,295 X10 + 7,072 X11 + 1,881 X4 - 4,134 X13, where X2 is Foundation Work Cost, X10 is Wall Work Cost, X11 is Door Work Cost and Window, X4 is Column Work Costs, X13 is Floor Work Costs. This cost estimation model has been validated with an average error percentage of 0%. Metode Parametrik Analysis using the formula set out in Presidential Regulation No. 73 of 2011 Article 14: Total Project Costs = HSBGN x K x Project Area, where HSBGN is the Price of the State Building Building Unit and K is the multiplier multiplier for multi-storey buildings. This cost estimation model has been validated with an average error percentage of 32%. Based on the results of this error percentage, it is concluded that the most accurate method is the Cost Significant Model.To obtain a small earth (near zero) resistivity value is determined by the number of planted electrodes and soil type properties. Difficulty in obtaining this small resistivity value often errors in estimating soil properties or soil type resistance so that failure to obtain soil barriers often occurs.To determine the desired amount of material can be measured soil type resistor value, by measuring the soil resistivity value so that the estimated material cost estimation can be achieved well. then in this research using geoelectric method with Schlumberger configuration. Schlumberger method is a method with a constant system of spacing rules with the note of the 'n' multiplier is the comparison of the distance between the C1-P1 or (C2-P2) electrodes with P1-P2. The instrument used is a resistivity meter ( Naniura) equipped with four electrodes which have the ability to read output voltage response due to current injected into the ground surface through two current electrodes and two potential electrodes. In this study used progress to map the 2D isoresistivity beneath the measured surface. .The results of this soil resistivity measurement can be determined with certainty the amount of material used and the cost of workmanship provided to establish the proper grounding system to be attached to a 20 kV Distribution substation at the State Polytechnic Padang State Electricity Laboratory. So that the grounding system in pairs meet the standards that have been determined and can be categorized both and safe for humans and equipment for grounding Distribution Distributors 20 kV Electricity Engineering Laboratory at the State Polytechnic Campus Padang.

The basic principle of metal formation is to change shape by giving an external force so that plastic deformation occurs. One example of this formation is wire drawing. The important parameter in wire drawing is the drawing force, which is the force needed to deform the wire to produce the desired reduction. The measurement of withdrawal force is carried out through a wire drawing test equipped with a dynamometer, which consists of load cell and strain gauge. From this test, the withdrawal force can be measured as an electrical quantity that can be read using a multitester or computer. For wire drawing testing dynamometers are designed and made as measuring sensors for withdrawal forces on a laboratory scale. From the results of testing with a dynamometer the average wire drawing force for copper reduction I was 72.88 kgf, copper reduction II was 95.88 kgf and brass was 126.50 kgf. The price of this test is greater than the theoretical price

One of the diseases that can be detected through blood tests is Dengue Hemorrhagic Fever (DHF). The number of platelets are one of the guidelines used by doctors diagnosing DHF. Actually, platelets can be calculated manually, but it will be very difficult if the platelets are counted quite a lot. So, we need a technology that can calculate the number of platelets quickly and automatized to get more accurate results. The automatic systems built by using the template matching method with image processing include HSL Segmentation with Luminance type and Reverse Color Manipulation. After building the system, the system will automatically look for objects that match the template in the sample image and then give the marking and calculate it.The overall system testing results are the number of platelets which are then classified manually at what degree of DHF.

WSN (Wireless Sensor Network) is a network consisting of several sensor nodes that form a collaboration in a WSN technology network using sensors. The WSN system can be implemented on an electrical energy meter. Electrical energy measuring instrument (kwh meter) is important for the community because it is related to the amount of the electricity bill. In the use of electrical energy, sometimes people do not know how much energy has been used in a month, so there is often a waste of electricity. The main purpose of this system is in the framework of transparency and provides information on per-kWh load rates in the use of electricity.The method used in making WSN implementation on this electrical energy measuring instrument is analyzing the problem, designing the system, making the system up to system testing. By carrying out these steps, the WSN implementation on this electrical energy measuring instrument can provide monitoring effectiveness and can find out how much per-kWh costs in the use of electrical energy.This system is programmed using the C language on Arduino. The devices used are Arduino Nano as the main controller, nRF24L01, ZMCT103C, LM358, LM2917N, and RTC. From the discussion it can be concluded that this system can help in knowing the cost of electricity usage per-kWh and can monitor the use of electrical energy using a PC (Personal Computer).
