Abstract

The construction of simple houses is always done, to meet the needs of low and middle-income people. And every time you make a home, it requires a fee to buy materials, equipment and to pay workers. So estimating the cost and material requirements at an early stage is very important. But, there is no simple cost and material estimation method, at the conceptual stage, when there is very little data information, so this is a problem for non-professionals. The solution to the problem is a theory. The theory is a program which consists of models. So this study intends to create a program, as a conceptual estimate. The quantitative method in this study uses 36 data on the Budget Plan. The data is processed using the Burgerlijke Openbare Werken (BOW) method. Then the results of the data process were analyzed using the linear regression analysis method, to get the model. The models then form the formula for the program. So that in this study produce models and applications, to estimate the cost and material requirements for the construction of simple houses. Using the program, enter the building area data information, and automatically, the cost and material requirements for the development of a simple house will be predictable. This program is a simplification of the Burgerlijke Openbare Werken (BOW) method.

Abstract

To minimize the number of work accidents in construction work, especially in irrigation work. Irrigation construction service providers must provide costs for occupational safety and health purposes taken from the total project costs. This study has the aim of knowing the amount of occupational safety and health costs required according to Circular Number 11/SE/M/2019 (SE19). The research was carried out using the literature study method where the stages of data analysis were compiling a list of risks that occurred, assessing risk, mitigating risk, calculating occupational safety and health costs with the price survey results and calculating the percentage of occupational safety and health costs to the contract. The results showed that 27 occupational accidents and safety risks were identified with 18 low risk categories and 9 moderate risks. The required occupational safety and health cost based on the contract is Rp. 11,961,000.00 while the cost based on the SE19 regulations is Rp. 18,350,000.00.

Abstract

Bridges are connecting access between one region and another, and play an important role in transportation to facilitate community economic activities. The river bridge has very steep cliffs, and these cliffs often occur in landslides, therefore this study is very important to determine the safety of the bridge. This study aims to determine the safety of the bridge abutment structure which is the head of the bridge with the function of continuing the load on the bridge foundation. This analysis is limited to only calculating the stability and safety of bridge abutments with reinforced concrete structures. The analysis uses methods and formulas referring to Indonesian national standards, namely RSNI T-02-2005 regarding loading for bridges, RSNI T-12-2004 concerning concrete structure planning for bridges, SNI 03-2833-200X concerning earthquake resistance planning standards for bridges. The data used are drawing data and technical specifications used on the bridge, then the data is verified against planning consultants, project implementers, and observations at the location. The results of the analysis stated that the bridge abutment was declared safe from soil thrust and other forces, but did not have a good safety factor against shear forces. Landslides that occur can be resisted by the bridge abutments. This research is expected to be followed up by policymakers to repair bridges so that they are resistant to maximum shear forces, and provide safety signs from landslides to relieve public anxiety when crossing bridges, as well as provide reinforcement for the cliffs around the bridge.

Abstract

One of the methods used to control the stability of the soil so as not to experience a landslide is to build a retaining wall. In carrying out the work, of course, it is necessary to pay attention to occupational safety and health for all those involved in a project, including the community around the project, therefore, it is important to calculate costs before starting work, so that the project can be carried out properly according to regulations, objectives, functions, benefits, impacts, costs, quality, time, and K3 or occupational safety and health. This study aims to determine the cost of retaining a cliff wall using the main material of mountain stone/split stone, including labor costs, materials, tools, and occupational safety and health (K3) costs. This research uses quantitative descriptive method. To complete this research, we need data on the budget plan for the construction project for the construction of retaining walls, and factual costs at the project site. The data sources consist of project documents, contract documents, and direct observations on site. This research has identified the cost of materials, tools, labor, and K3 in units converted to cost/m3, and produced a coefficient of unit price analysis for retaining wall work. The results of this study can contribute to estimating the cost of retaining wall work using mountain/split stone specifications at an early stage during planning, using unit costs/m3 of work, both by planners, contractors and the general public.

Abstract

This study aims to find out how to plan the Reinforced Concrete Bar Frame Structure which includes the structure of columns and beams and their reinforcement to meet the design concept of capacity, namely strong columns and weak beams. In this study, it will be planned on the Nusa Putra Islamic Boarding School building which amounts to 3 floors using the Special Moment Resistant Frame System (SRPMK) in accordance with SNI-2847-2013 and SNI-1726-2012. The earthquake load used is Spectrum Response Analysis by taking into account three different types of soil conditions namely hard, medium and soft soils. Moment Resistant Frame System is a spatial frame system in which structural components and their joints resist forces acting through bending, sliding and axial action. The quality of the concrete material used is 25 MPa and the reinforcing steel material used 400 MPa threaded iron while the beam dimensions are 300 mm x 400 mm and the column is 500 mm x 500 mm. The results obtained on the beam structure in hard soil conditions Mu = -85.5012 kN (support for) 4D19; Mu = 42.7506 kN (pedestal under) used 3D16; and Mu = 30,2581 kN (in the middle span) used 3D16; on medium soil Mu = 92.0741 kN (support for) 4D19; Mu = 46.03705 kN (lower pedestal) used 3D16; and Mu = 59.4276 kN (center span) used 3D16 + 1D13; on soft soil Mu = -107,842 kN (upper support) 5D19 was used; Mu = 53,921 kN (pedestal under) used 4D16; and Mu = 63.4546 kN (center span) used 4D16; Axial force occurs in the main column due to the combination of the three types of soil is not too significantly different, on hard soil = 337,949 kN, medium soil = 339,785 kN, soft soil = 342,954 kN, so column reinforcement in all three uses 12D22

Abstract

Writing research reports at the undergraduate level is one of the obligations that must be fulfilled by students as a fulfillment of graduation requirements at a university. One of the independent learning programs implemented at Nusa Putra University is through the research method, where students are required to conduct research as a graduation requirement in the Study Completion Program course. The growing development of information and communication technology provides opportunities for students to determine research themes. However, sometimes students take research themes that are not in accordance with the concentration in the study program. This research was conducted with the aim of identifying how the LDA topic modeling method can analyze research topic trends by modeling topics on research titles that have been taken by students at the Informatics Engineering Study Program, University of Nusa Putra. Latent Dirichlet Allocation (LDA) is one of the most popular topic modeling methods today. This research uses a dataset in the form of 159 titles of study completion program research reports and tittles of final assignment reports for students of the Informatics Engineering study program, University of Nusa Putra. This research is expected to be a reference in conducting research by students based on the topics that have been modeled
