Abstract

Material is one component of the cost that plays an important role in supporting the success of a project. In the implementation of building construction projects, leftover materials or Construction Waste cannot be avoided. Excess material, whether from work results or from construction materials that are left/scattered/destroyed and cannot be used again, is called construction waste. Thus, a method is needed for the efficiency of remaining construction materials (Intan et. Al,2005). Construction in Indonesia currently has many problems regarding inefficiency in the implementation of construction. The causes of this inefficiency include poor performance, waste of resources used during the construction process, but this does not add value to the function of the resources used. Based on data submitted by the Lean Construction Institute (LCI), waste in the construction industry is around 57% and activities that provide added value are only 10% (Abduh, 2007). In construction projects, problems are often found in the construction process, such as changes to project drawings, changes to specifications, poor storage, and other technical problems in the field that cause material waste. Problems like this can have an impact on project cost losses beyond what was planned.Lean Construction is very necessary in construction projects so that waste does not occur due to the problems that have been explained previously, it is hoped that it can reduce waste on the project. So that it can reduce costs caused by waste and can establish better relationships between individuals involved in the project.

Abstract

Clean water is a need for every living creature. Clean water is water that physically looks clear and has no smell that is used for daily purposes and can be cooked to make drinking water. In carrying out daily activities, humans need clean water. One of them is in teaching and learning activities at an institution. To ensure comfort in the teaching and learning process, it is necessary to plan the consumption pattern for clean water needs in lecture buildings, one of which is on the Sriwijaya State Polytechnic Teaching Industry campus. Considering the number of academics who will actively carry out activities on this campus, it is necessary to study the planning for clean water usage to obtain water consumption patterns. The research was carried out by taking samples of two buildings, namely buildings E I and E II which were planned as Workshop lecture buildings. Based on calculations and data analysis for planning clean water consumption patterns at the Sriwijaya State Polytechnic Teaching Factory campus, it is 7200 liters/day or 0.083 liters/second for Building E I and 7200 liters/day or 0.083 liters/second for Building E II.  The reservoir volume is planned with a capacity of 18 m3 and the tank volume with a capacity of 1 m3.

Abstract

Substructure is more commonly known as a foundation. Foundations come in many types, and the selection of the foundation type is based on soil conditions, technical requirements, environmental factors, and cost. One of the key factors in choosing a foundation is the soil bearing capacity in the area under consideration. Soil bearing capacity refers to the soil's ability to withstand all the loads acting on it. Before designing the foundation, it is essential to determine the soil bearing capacity. Soil bearing capacity is obtained from soil tests, such as the Cone Penetration Test (CPT) or Sounding. The method used in this study employs a quantitative approach with the analysis of secondary data. Based on the results of the soil tests using CPT, with cone resistance values ranging from 139 kg/cm2 to 198 kg/cm2 at depths between 11 meters to 16 meters, mini-pile foundations are used. The dimensions of the mini-pile plate are 10,000 mm x 3,800 mm x 500 mm, and 6 concrete piles with dimensions of 250 mm x 250 mm are used. The total number of 250 mm x 250 mm concrete piles required is 2.

Abstract

Construction activities require concrete as a widely used material. Concrete consists of several compositions, namely fine aggregate, coarse aggregate, water, and Portland cement as the main material for the binder. Cement production contributes around 6% of carbon emissions which can damage the environment, including global warming, and the use of high levels of cement material in concrete mixtures, so alternative materials are needed to replace cement or cement additives for concrete mixes. Alternative materials used in this research are fly ash and silica fume. This research aims to determine the test results and characteristics of concrete using silica fume and fly ash as partial cement substitute materials as well as the effect of the ratio of silica fume and fly ash on the compressive strength of concrete. The research was carried out by direct testing in the laboratory. The various mixtures of Fly Ash (FA) and Silica Fume used are: FA 10% and SF 5%, FA 15% and SF 5%, FA 20% and SF 20%, FA 25% and SF 10%. Based on the results of compressive strength tests carried out at 28 days of concrete, it shows that the use of silica fume and fly ash to replace cement cannot be said to have succeeded in increasing the strength of the concrete. The highest compressive strength value was achieved by variation 3, namely with a fly ash content of 20% and 10% silica fume, producing a compressive strength value of 19.44 Mpa, this shows that the strength achieved is still limited to low quality concrete below 20 Mpa.
