Settlement as a container for community activities to settle there are 2 primary physical elements, namely the Solid element (building) and the Void element (open space). Public open space as a void element is a space that is not built up in an area of the city that is functioned for the aesthetics and welfare of its citizens, public open space must have a responsive, democratic, and meaningful character. The study was conducted based on the Qualitative paradigm with the main search technique was field observation, a theory which, supporting this research, was used as background knowledge. To find out the typology of the interaction space, an overall observation was carried out to divide the research area large enough into small units to simplify the process of research analysis. The location of the study, namely the Tambak Lorok Fishermen Settlement City of Semarang, at the overall observation stage found differences in the livelihoods of the population, increasingly in the middle of the settlements dominated by fishermen. Interaction space is influenced by physical and non-physical aspects, physical aspects related to the physical condition of the research area, non-physical aspects related to the social culture of the community. The research area is divided into 3 observation units, the TPI area, the Mooring Pier area, and the large mosque area. Differences in physical and non- physical aspects are believed to produce different typologies of interaction space. The determination of aspects of typological analysis is carried out by analysis based on findings in the field.rmukiman sebagai wadah dari kegiatan masyarakat untuk bermukim terdapat 2 elemen fisik primer, yaitu elemen Solid (bangunan) dan elemen Void (ruang terbuka). Ruang terbuka public sebagai elemen void merupakan ruang yang tidak terbangun dalam suatu area kota yang difungsikan untuk estetika, dan kesejahteraan warganya, ruang terbuka public harus memiliki karakter responsif, demokratis, dan bermakna. Penelitian dilakukan berdasarkan pada paradigma Kualitatif dengan teknik pencarian utama adalah observasi lapangan, teori yang ,mendukung penelitian ini digunakan sebagai background knowledge. Untuk mengetahui tipologi ruang interaksi dilakukan observasi keseluruhan untuk membagi daerah penelitian yang cukup besar menjadi unit kecil untuk mempermudah proses analisis penelitian. Lokasi penelitian, yaitu Permukiman Nelayan Tambak Lorok Kota Semarang, pada tahap observasi keseluruhan menemukan perbedaan mata pencaharian penduduk, semakin ke tengah permukiman didominasi oleh nelayan. Ruang interaksi dipengaruhi oleh aspek fisik dan non fisik, aspek fisik berkaitan dengan keadaan fisik area penelitian, aspek non fisik berkaitan dengan sosial budaya masyarakat. Area penelitian terbagi menjadi 3 unit amatan, area TPI, area Dermaga Tambat, dan area masjid besar. Perbedaan aspek fisik dan non fisik diyakini menghasilkan tipologi ruang interaksi yang berbeda. Penentuan aspek analisis tipologi dilakukan dengan analisis yang dilakukan berdasarkan temuan di lapangan.

Nowadays, the use of portland cement in concrete can pollute the environment because the pollution caused by portland cement factories. Therefore, the enviromentally friendly materials which have the properties of portland cement are needed to reduce the proportion of portland cement and at once can improve the quality and the characteristics of concrete. This study aimed to determine the increase of ealry compressive strength of concrete with added materials Sikament NN and fine powder of CaCO3 and fly ash. The innovation of admixtures that we use in order to subtitute the proportion of some portland cement are CaCO3 powder as type C admixture (accelerator) and Fly Ash type C with the precentage of each is 10% and 30% of the total weight of portland cement. In order to improve the workability of concrete, we use type E admixture (accelerator and water reducer) with the name of product is Sikament NN by 1,5% of the total weight of portland cement. The Mixing method used is SNI-03-6468-2000. The desired compressive strength of concrete with added materials CaCO3 powder, fly ash and sikament NN at age 1 day in mix design is 15,31 MPa and the slump value is 22,5 cm. the result showed that compressive strength of concrete at age 1 day with those admixtures is 17,19 MPa and the slump values is 23 cm. From the datas we know that concrete with added materials CaCO3 powder, fly ash and sikament NN can increase the early compressive strength about 12,3 %.

One of the work items in the Soekarno-Hatta Airport Accessibility and Ducting Utility Project is widening the M1-M2 road. Pit test results in that area indicate that there is a 40 cm (16 ") diameter Pertamina pipeline at a depth of 0.7 m. The pipe is used to flow aircraft fuel so it is not possible to be relocated, this condition is called road crossing pipeline. Alternative solutions to overcome these problems are road elevation and the making of pipe protection from concrete. Road elevation costs as much as Rp 13,626,916,287.02 compared to alternative construction of pipeline protection amounting to Rp 23,200,588,370. The time for completing the elevation of the road is faster, which is around 47 weeks, while the implementation of the road and making pipeline protection takes 61 weeks. In terms of quality, in soil compaction during the road elevation process uses a vibroroller so that compaction is evenly distributed. Based on the comparative results in terms of cost, time and quality, the alternative solution to the problem road crossing pipeline is road elevation.

Demand uncertainty and traffic forcase uncertainty can lead to inaccuracies in the estimation of the revenues which are supposed to cover construction, operation and maintenance of toll roads. In addition, the delay in construction projects results an increase in the planned execution time of the project and increased in construction costs. This study focuses on the effect of project delays and the risk of traffic prediction in toll road project investments. The basis of this research is find out impact of the risks in project to feasibility analysis, so that the changes in the value of the investment feasibility indicator in bisnis plan can be obtained. This study carried out using several technical economic methods to obtain the value of the investment feasibility indicator such as NPV, IRR, BCR and WACC. Pantura is the only one road which people use to move from Pejagan to Semarang. Therefore, an alternative road is needed to break traffic such as Pejagan-Pemalang Toll Road. Obtain from the calculation results, there are 4 risk comparison methods : analisis investmen according to business plan, project 2 years delay with business plan traffic, project on time with existing traffic after toll road operation and project 2 years delay with excisting traffic. The value of NPV, IRR and BCR after 2 years project delay with existing traffic are Rp6,541,793,515,548, 9.1%, 1.239 and 8,5%. After comparison, the risk of construction delay affects significant changes in IRR and BCR, while the error traffic prediction results in a large NPV change, and the error in traffic assumption is the most influential risk for finance in the Pejagan Pemalang toll road construction project.

Environmentally friendly concrete is concrete composed of materials that do not damage the environment. The need for the use of environmentally friendly materials in the manufacture of high quality concrete that is environmentally friendly needs to be continuously developed. To realize the concept of environmentally friendly and high-quality concrete in the concrete experiment this time used granite broken waste as a partial aggregate of coarse aggregate, as well as shell and powder ash shells as a partial cement substituent. Using waste that is not appropriate and is converted into an appropriate substitute material is expected to produce high quality concrete and environmentally friendly concept, because the use of unused waste is expected to reduce the amount of waste that is around the Surakarta area. With the use of granite fragments, shells and fly ash, the compressive strength is targeted at 1 day of age is 22 MPa and 28 days is 47 MPa.The mix design method used is the SNI method (Indonesian National Standard). Mix design in the manufacture of environmentally friendly concrete refers to the use of granite broken waste as a partial substituent of coarse aggregate, the use of shell shell waste of 7.5% of the total cement weight, and the use of fly ash of 25% of the total cement weight. With FAS of 0.3%, and the use of admixture in the form of Superplasticizer of 0.6% to accelerate the achievement of quality earlier in the first week.

Ketapang regency is an area rich in marine natural resources and plantations. Ale – ale mussels are a potential marine natural resource whose capture produces negative impacts in the form of shell waste. And the natural resources of the plantations are oil palm which produces kernel shell waste and plywood wood companies which produce waste from machine glue. Where, these wastes have not been managed optimally. This is a challenge in research so that waste can be used as a mixture of concrete, has economic potential and reduces environmental impact. In this study, cylindrical samples with diameter (∅) 15 cm and height 30 cm. The percentage of waste is 30% of the weight of coarse aggregate. With a mixture ratio of 1 : 2 : 3 ( cement : fine aggregat, coarse aggregate ) with 3 samples from each type of waste to determine the compressive strength of 7, 14, and 28 days. The stages of implementation include the examination of material properties, sample making, weighing and the compressive strength test of the sample. The average compressive strength value of the 28-day age conversion obtained from the ale-ale shell waste test results was 177.64 kg / cm2, kernel shells amounted to 66.62 kg / cm2, and plywood glue amounted to 235.57 kg / cm2. Based on these data, plywood glue wastehas the highest compressive strength value.

According to data from the Indonesian Central Agency of Statistic, there are 708 shopping centers (malls) in Indonesia in 2018, this figure is equivalent to 4.45% of the total trade centers in Indonesia. The basic meaning of the shopping center is a public area that connects every store with the society. Based on the theory of Ray Oldenburg, an urban sociologist from the United States, “People spend the majority of their lives in one of three places. The first is the home, the second is the workplace, and the third is any other social space”. The shopping center is one part of “the third places”, people spend their time doing economics transactions or just relaxing in the shopping center. So that with the massively increasing development of shopping centers in Indonesia, it is need a construction design and building manage that more creative and based on eco-technology also maximize the “internet of things” as part of building operations. “Integrated Basement : Creating an Eco-Technology Basement with High-Tech Parking Area” is the main focus for the writer to design the basement as an underground building area that often used as a parking area to be a “smart parking area” and “green area” by focusing on how the building operations become efficient, environmentally friendly and high-tech integrated. Smart parking area also means that the basement be an area that can interact and be able to adapt to shopping center’s visitors. With this planning, hoped that urban society can enjoying the shopping centers as public area that environmental friendly, comfortable, also efficient and integrated.
