Abstract

The road conditions in the Fakfak Regency area have suffered a lot of damage, this is related to the subgrade condition of the road in the form of clay. One method that is widely used to improve the characteristics of clay that does not fulfill the requirements as a road subgrade material is to add fly ash. Aim of this study was to determine the value of clay plasticity before and after adding rock ash with the percentage of stone ash 8%, 16%, 32%. From the results of testing on clay soaked for 7 days can reduce the liquid limit value where the largest decrease is 15,24% of the original soil occurs in the addition of 32% fly ash with a value of 66,86%. The plastic limit value also decreased by 20,40% from the original soil with a value of 46,10% at the addition of 32% fly ash. And the plasticity index value experienced the largest decrease in the addition of 32% stone ash with a decrease of 0,97% from the original soil with a value of 20,76%. In clay soil which was brooded for 14 days the largest liquid limit value decreased which was 18.72% of the original soil occurred in the addition of 32% fly ash with a value of 64,11%. The plastic limit value also decreased by 21,77% from the original land with a value of 45,31% at the addition of 32% fly ash. And the plasticity index value experienced the largest decrease in the addition of 32% stone ash with a decrease of 10,32% from the original land with a value of 18,80%.

Abstract

Many parties are involved in a construction project, so in deciding a method of implementing the box girder erection many criteria are taken into consideration. Consequently, decision making is not easy for decision makers. A simple, frequently-used, and popular method for decision making is Fuzzy-Analytical Hierarchy Process (F-AHP) which is designed to overcome the problem of multi criteria decision making (MCDM) in the subjective assessment process. This study aims to obtain the correct method of implementing the box girder erection to be used. Based on previous research, the criteria for determining box girder erection method are the criteria for job risk, work quality, implementation time, implementation process, work safety, and work costs. The alternatives compared are the tandem crane method and the launching gantry method. The data in this study were collected through questionnaires distributed to the expert parties involved in Jakarta - Cikampek II Elevated Toll Road Project. F-AHP analysis is based on the weighting  of quantitative criteria as a result of normalized calculations and qualitative criteria from the results of the respondents questionnaires which were then made pairwise comparisons assisted by Microsoft Excel software. The results of the analysis show that the occupational safety criteria are the most influential criteria with a weight of 0.454, then followed by job risk criteria (0.169), implementation time (0.119), work quality (0.114), implementation process (0.084), and work costs (0.061). The most appropriate method used in the work of the box girder erection at Jakarta - Cikampek II Elevated Toll Road Project is a launching gantry method with a value of 0.597, while the tandem crane method has a value of 0.403.

Abstract

The need for housing is very rapid, especially the type of house growing with several choices of area, namely types 21, 27, 36, 45 to 120m2. In the growing house will be provided land for homeowners to develop the house so it is more feasible. The concept of housing provided by the developer is sometimes incompatible with the concept of utilizing natural lighting because it only emphasizes attractive design and number of units. For this reason, it is necessary to provide a reference for homeowners as a strategy to renovate buildings facing the west so that the utilization of natural lighting remains optimal and meets the measurement of comfort visually. The study will analyze the average lux value or Daylight Levels avarage of natural lighting resulting from the amount of light openings. The analysis will be done is the average value of natural lighting from the location strategy and the amount of light aperture in producing quality lighting in space. The kitchen room and family room are spaces with a high level of activity that require optimal lighting. The most optimal lighting level is the opening type of model 1 with 10% opening in the west, 10% opening in the roof, and 50% in the east. The resulting lighting level is 998.58 lux in clear sky conditions and 849 lux overcast conditions.

Abstract

It is the main and important element to be fulfilled, water becomes the primary need in all elements of life of living things so that they can continue to live life and all its activities. Besides that water is also in secondary needs as a means of transportation. Even water is also able to become a recreational facility so that water can also be said as a complement to tertiary needs. Water covers almost 71% of the Earth's surface. There are 1.4 trillion cubic kilometers (330 million miles) available on Earth. Viewed from the point of view of public health, the average volume of water requirements for each individual per day ranges from 150-200 liters or 35-40 gallons. The water requirements vary and depend on the climate, living standards and habits of the people. Reduced population of vacant land results in the availability of land to be reduced and limited. This makes the opportunity for hotel and apartment properties to increase. For some large cities, the presence of hotels and apartments is increasing every year, of course this will have an impact on the needs and availability of clean water that must be available every day. Because this research is very important to make an effort that is able to minimize the use of ground water by saving water and recycling water methods. The effort is able to be a solution to the efforts to create efficient use of ground water. Exactly this Water Management Infrastructure Engineering is carried out in the Grand Taman Melati Margonda Apartment 2. With a total unit reaching 939 units. Aspects that are the focus of the results of this study are aspects of quantity and cost.
