The development of technology and the demands on the speed of the construction project cause the material manufacturers compete to create a new material that can accelerate the process to build a building. Wall is one of the non-structural elements on a building. Both low-rise building and high-rise building are no doubts using this material. Wall works can use two different types of material, such as brick wall made of red clay and light brick wall made of cement, silica sand, and limestone. In the construction process wall is needed in a large amount of area, so the difference of the price should be examined in choosing the type of the material to gain efficient cost. The purpose of this study is to determine which method of wall construction is more efficient in terms of cost and time, the use of red brick wall or brick wall light. The study was conducted using survey, comparative, literature study method. Results indicate that both methods have advantages and disadvantages. Red brick wall method is cheaper in the cost of the process, while the lighter brick wall method much faster in the process.
Java is an island with the most populous population in Indonesia. With the potential of cultural diversity in Java, creative economic activities on this island need the development. The local wisdom and cultural events are reflecting the creativity of the community and can provide economic value to the community. The physical quality of creative economic spaces that can become generators in some cultural tourism areas does not have functional quality space. To support the preservation of cultural heritage and the development of superior cultural tourism areas, the quality of an excellent creative economic space is necessary. The aim of this study is to identify physical quality of space for creative economic activities or events. The method of this study used a qualitative descriptive method. Results of this study provide an overview that cultural village in Semarang and Banyuwangi have five potential creative economic activities: traditional architecture, culinary, crafts, music, and performing arts. The physical quality of these two creative economic spaces is still limited because of the limited economic capacity of the community in providing the spaces. They are shaping and realizing space with utilizes natural conditions (green open spaces or spaces among tall trees) and local material (bamboo).
Concrete-Mold is one of the most important elements of a building’s structural system. Like other structural systems, the concrete mold placed right after the main wiring structure placed. The function of the concrete mold is to specify the size of the concrete structure itself. The needs of an efficient construction timeand cost are some reasons of the decent and fast development of home-design structure. Sloof’s concrete-mold for two-floor houses can be done with two different materials, i.e. wooden plywood material and bricks. The difference usage of these two materials is the background of this research. The purpose of research is to find out the best way in time and cost efficiency of these two materials. This research carried out using the method of library studies, survey, and comparative study. The result of this research showed that the cost of the brick making the job of sloof concrete mold cheaper and faster. Thus, sloof concrete mold making is one of the project solutions that are more efficient in terms of time and cost.
This article contains a research on position and placement of solar panels to reduce electrical energy consumptionof an office building with analysis on sunlight of the site, which located in Lebak Bulus, Kawasan Koridor, Jalan TB Simatupang, South Jakarta. The method of the research is as follows: (1) Analyze the site location, (2) Analyze the climate in the site location, (3) Analyze the solar panels placement based on the result of analysis of sunlight, (4) Analysis of Electricity Supply Demand Calculation in Buildings, and (5) Calculate the efficiency based on the amount comparison of electricity needs of the air conditioner and the energy produced by solar panels. The result shows that solar panels will work optimally if placed on the upper side, the northeast side and the northwest side of the building. The amount of solar panel needed are as many as 4,398 pieces, based on comparisons between energy consumption and building area. So, it can be concluded that the use of solar panels on the top side, and 2 other sides namely east and west can produce electricity use efficiency of 53.08%.
