Abstract
- Every construction of home, made a Bill of Quantity is very important. Due to the basis for outlining the budget plan as well as the basis for calculating
human resource needs, money resources, material resources and other resources are depend on the Bill Of Quantity. But, without supported by the completed
data, the bill of quantity can’t be compiled. How to compile Bill of Quantity if the information data is known only building area without any other data.
The solution of the problem is “model”, by the existing model, the program can be formulate to compile the Bill of Quantity in the house construction project. To get the model and arrange the program, the research is done by using quantitative method, the research is also supported by primary data. That is by
doing the project of house construction directly. And secondary data by survey and interview to the construction contractor. Data is processed then do the regression analysis to produce the model as a formula to arrange the Bill of Quantity.
This research is finally yield a program to develop Bill of Quantity with building area as the data input. The Bill of Quantity is automatically arranged by
entering the variable of building area.
introduction
The house is a basic human need so that the construction of houses in big cities, towns and villages is
always done. Even the Indonesian government has set it in Act No. 1 of 2011 on housing and residential
areas. Each undertaking the house construction, needs to be prepared design drawings and resources
that include, material, human, money, machinery and other tools, as well as implementation of construction method, as well as implementation of construction method.
This research is intend to find the Bill of Quantity (BOQ) of house construction with data input only
building area, for example having a plan to build a house with 3 bedrooms, each of them is 9m 2, living
room is 12m2, kitchen is 9m2 and terrace is 6m2, so the total of building area is 74m2. So, how about the
BOQ? This study is aims to produce a simple method to find the BOQ with building area as data input
OBJECTIVE
This research uses quantitative method, to complete this
research then required data, the required data is Bill of Quantity in budget
source consist of project document and contract document. Then the data
to get the model. Furthermore the model into a Bill of Quantity formula
plan of home construction project, the data
is processed and done the regression analysis
compiled on the excel program.
Secondary data as many as 24, are obtained by interview and survey
to construction contractor. Secondary sampling data obtained from The Spring housing as many as 250 units taken
5 samples, from The View housing as many
as 250 units taken 5 samples, from Melati Loka housing as many as 275 units taken 5 sample, from Cibeureum Permai housing as many
as 350 units taken 5 samples and individual house taken 4 samples. The number of primary and secondary data is 38 samples.
To perform regression analysis,
firstly processed the data into measured variables.
It can be assumed that the dependent variable (Y)
is the volume and extent of the item of the building component,
expressed y1 (the volume of concrete structure), y2 (wall area),
y3 (number of sills, door),
y4 (floor area),
y5(sanitary number) ,
y6 (the number of ME),
y7 (foundation volume),
y8 (roof area),
y9 (paint area),
y10(ceiling area
while the independent variable (X) is the building area
CONCLUSION
By finding the regression model as a formula to identify the volume and extent of building components of

minimalist house with minimum building area of 21 m and maximal 290 m . Then by doing the 12 steps, Bill of
Quantity program of house development project has been arranged, just only enter the variable x (building area)
into the program, automatically the volume and extent of building components on Bill of Quantity of home construction project will be identified. The resulting model as the formula is:
Model y1 (struktur beton) = 3.927 + 0.171X.
Model y2(dinding) = 100.968 + 2.126X.
Model y3 (kusen pintu, jendela) = 10.518 + 0.090X.
Model y4 (lantai) = 0.449 + 1.074X.
Model y5 (sanitary) = 9.879 + 0.072X.
Model y6 (ME) = 12.863 + 0.323X.
Model y7 (fondasi) = 2.416 + 0.125X.
Model y8 (atap) = 37.322 + 0.463X.
Model y9 (pengecatan) = 126.447 + 5.334X.
Model y10(plafond) = 13.388 + 0.953X.
The validation model has been tested and applied to Bill of Quantity program with accurate results.
