The project for the construction of the Muntilan Christian Church Building in
Muntilan, Magelang Regency, Central Java, which is viewed from the Structural,
Geotechnical and Construction Management Sector, was prepared by Adithya Aladar
(191317568) and Nafarani Bongga (191317834). The Muntilan Christian Church
building consists of 2 (two) main buildings, namely the Church Building and the
Management Building which are connected by connecting bridges on the 2nd, 3rd and
4th floors. However, in this design the author focuses on designing building 1 or the
Church Building. . The design of this building covers three areas, namely Structure, Geo-
Engineering and Construction Management which are interrelated with one another.
In designing the Indonesian Christian Church Building the method used is a
quantitative research method in which the author must collect numerical data or numbers
so that conclusions can be drawn from existing calculations, for example such as the
design of columns, beams and floor slabs to the analysis of project costs and time. The
structural material specifications used in this design include the Profile Steel used is BJ
342 with a yield stress of 240 MPa and Ultimate Stress of 370 MPa, Modulus of elasticity
of steel 200,000 MPa, Concrete compressive strength at 28 days old with fc' 30 MPa. For
cost and time management, everything is guided by SNI by using the newest Work Unit
Price Analysis each year according to the given project location. Calculations made
always refer to working drawings which contain the terms and conditions that apply.
The structural design of the Muntilan Indonesian Christian Church begins with
the calculation of the roofs of building 1 and building 2. In planning the roof structure,
the church Muntilan Indonesian Christians use the WF roof. Structural columns have one
size, two types of main beams, one type of child beams, and four types of floor slabs.
The design in the field of Geo-Engineering at the Muntilan Indonesian Christian
Church has a sandy loam soil type obtained from the interpretation of soil data from the
SPT and CPT tests, because it is based on the calculation of the carrying capacity of the
piles compared using two methods, namely Meyerhoff and Briau et al, in the construction
of the Christian Church building Indonesia Muntilan uses a pile foundation because it has
a safe limit at a depth of 18 meters.
Design in the field of Construction Management for the Muntilan Indonesian
Christian Church includes the preparation of WBS, calculation of activity volume, unit price analysis, calculation of activity duration, Precedence Diagram Method, Network Diagram, Barchart, S-Curve, Worker Scheduling and Budget Plan. So from the calculations and analysis above, the Muntilan Indonesian Christian Church takes a total of 323 days (11 months) with an estimated cost of Rp. 31,733,896,353,719.37 In the field of Construction Methods the drafting team used Unit Price Analysis in accordance with the project location, namely in Magelang.
