Abstract

Semarang City is the capital city of Central Java Province, Indonesia as well as the fifth largest metropolitan city in Indonesia after Jakarta, Surabaya, Medan and Bandung. As one of the most developed cities on the island of Java, Semarang City has a population of 1.68 million people. Semarang Ahmad Yani Airport is the most important airport in Central Java. The existence of the airport in the city of Semarang is quite strategic because it is supported by the high intensity of socio- economic activities. Ahmad Yani Airport itself is part of a series of activities in Central Java. As a service-based city, the city of Semarang certainly requires an airport that is able to connect not only national but also international points. The aim of this research is to analyze the conflict points of congestion at the study site after the construction of the Ahmad Yani Airport Flyover and compare the degree of saturation (S) before and after the construction of the Ahmad Yani Airport Flyover. This study is used the 1997 Indonesian Road Capacity Manual (MKJI) method. Results of the analysis concluse degree of saturation 0.16 < 0.19 for the Puri Anjasmoro road section, and 0.19 < 0.28 for the Anjasmoro Raya road section. Meanwhile, the degree of saturation for the Ahmad Yani Airport Flyover Road section, Semarang is 0.10.

Abstract

Hydraulic aspect of the weir is important factors in planning a stilling basin. Remaining energy on the stilling basin is expected to be as minimal as possible so that scour does not occur on the river bed. Plaosan Weir does not yet have a stiiling basin structure. Therefore it is necessary to recommend the design of stiliing basin.The analysis carried out hydrological analysis, including calculating return period rainfall, flood discharge (Q) using the Haspers method, and calculating Froude number (Fr) to determine pond type. Based on the recommendations for the type of stilling basin, a building design is carried out and also stability of design..From the results of calculation it is obtained that 50-year return period rainfall is 108.68 mm. Planned discharge for 50 years is 186.06 m3/s, and froude number : 4. The appropriate type of stilling basin is USBR Type IV. The pond is planned to have a length of L = 17 m, with a block face width of 0.68 m, height of 1.36 m, distance between front blocks of 1.69 m and total of 13 pieces. The results of stability control analysis during normal water conditions and flood water conditions produce values above the safety factor so that it can be concluded that the design is planned qualify.

Abstract

Paving block is an environmentally friendly construction where paving blocks are very good at helping groundwater conservation, implementation is faster, easy to install and maintain, has a variety of forms that add aesthetic value, and the price is easy to reach. Therefore, paving blocks are an important building material in the construction of public facilities, especially for road construction in residential areas. The use of paving blocks in the field is still limited to parking lot pavements, sidewalks, parks and connecting buildings. Even though the application of paving block materials is very wide. However, of course, local experience and the successful use of paving blocks will play more and more influence in terms of the application of these materials. Stone ash in this study was used as a substitute for natural fine aggregate (natural sand) with the proportions of 0%, 15%, 30%, 45%, and 60%. To get the optimal compressive strength value, the researcher has the opinion of a combination of fine aggregate of natural sand and rock ash waste with the appropriate percentage. And tested with mortar age of 14 days and 28 days. In the study, the volume weight test of paving blocks with the addition of stone ash waste obtained the highest compressive strength at a variation of 45% for the test at the age of 14 days and 28 days, with the compression test for 14 days reaching a compressive strength of 100.92 kg/cm2 and for the compressive test 28 day reached a compressive strength of 160.28 kg/cm2.

Abstract

This study evaluates the comparison of compressive strength between conventional concrete and concrete mix with used tire aggregate, focusing on its influence on compressive strength and concrete weight. The testing used cylindrical specimens with variations of used tire addition at 3%, 6%, 9%, and 12% of the coarse aggregate volume. The targeted concrete design strength is fc' 20 MPa at 28 days. Experimental methods were employed to compare their mechanical properties, measuring compressive strength and concrete weight across different mix compositions. The results for normal concrete yielded an average of 30.96 MPa, while for 3% tire mix yielded an average of 30.12 MPa, 6% tire mix yielded an average of 25.51 MPa, 9% tire mix yielded an average of 22.51 MPa, and 12% tire mix yielded an average of 21.54 MPa. The reduction in concrete weight for 3% tire mix was 0.035 kg from normal concrete, for 6% tire mix was 0.04 kg from normal concrete, for 9% tire mix was 0.23 kg from normal concrete, and for 12% tire mix was 0.35 kg from normal concrete. The study findings indicate that concrete mix with used tire aggregate exhibits competitive compressive strength with conventional concrete, while showing a tendency towards lower weight. The implication is that concrete mix with used tire aggregate has the potential to be a lighter and mechanically strong alternative. This study provides important insights for the construction industry in seeking more sustainable and cost-efficient solutions, while reducing the environmental impact of used tire waste.
