Area C of Kadiri University is an empty land located west of the campus area. The land is planned to construct buildings C, D, and E as a projected study area. In carrying out infrastructure development, it is necessary to have a mapping framework to coordinate building plans. Determining the zero point of action requires a land survey to determine the strategic position and the need for excavation or fill. The method used is a closed polygon with vertical and horizontal theodolite shooting tools. The results of the field details showed several projections of the building plan column from survey data on the location of the P1 device with coordinates 31900'43" elevation 123.93 MASL to the northern azimuth value, location P2 with coordinates 291035'48" elevation 125.07 MASL to azimuth P1, location P3 with coordinates 302023'58" elevation 124.179 MASL to azimuth P2, location P4 with coordinates 29040'50" elevation 123.96 MASL to azimuth P3 and location P5 at coordinates 193056'47" elevation 124.48 MASL to azimuth P4.

Concrete is a building construction material that has an important role. Concrete itself tends to have strong properties in resisting compressive forces, but weak in resisting tensile or flexural forces. The use of additives in concrete is an option to improve the basic properties of concrete. Latex or rubber latex is one of the natural materials that can be used in concrete mixtures. Its adhesive properties can be utilized in improving the quality of concrete. This study aims to determine the compressive strength and flexural strength of concrete with the addition of latex. The research was conducted experimentally by making concrete specimens in the laboratory. The addition of latex by 10% and 30% with a planned concrete quality of fc' 29.5 MPa. The test object used is a cylinder measuring 15x30 cm and a beam measuring 15x15x30 cm. The tests carried out were testing the compressive strength and flexural strength at the age of 28 days. The results showed that the highest compressive strength was at the addition of 10% latex with a value of 9.96 MPa. While the highest flexural strength value obtained was 3.20 Mpa at the addition of 10% Latex or. From these results it can be seen that the addition of latex has not been able to improve the quality of concrete and has not been able to increase the compressive strength or flexural strength of concrete. So that these results can be used as research development or concrete production.

The stability of the soil structure is something that needs to be considered in development. Increasing soil structure improvement can be done through various efforts using added materials or compaction processes. This study aims to improve the clay soil on the kerot kediri road using paper waste. The research was conducted experimentally by making samples in the laboratory. The land used is from the Totok Kerot road, Kediri, which has damaged the road surface due to land loans. Waste paper was added at 0% 7.5%, 10%, 15%, and 20% of the weight of the test object. Waste paper is used with pulp after it is dried and pulverized to a certain gradation. The tests carried out include the Consistency Limit (Atterberg Limit) and Soil Compaction (Proctor) tests. The results showed that the addition of waste paper affects the original properties of the soil. The addition of paper moisture content decreases the Plastic Index value and increases the dry volume of the soil. The addition of waste paper content also increases the volume of dry soil water but decreases after reaching the optimum point, namely at 10% paper waste content and 9.96% water content with a dry volume weight value of 1.97gr/cm3. The greater the dry volume of soil, the dry density indicates that the soil is getting higher. So that by knowing these results, it can be used as a reference in the process of repairing and backfilling the soil on the Totok Kerot Kediri road.

Concrete is a form of construction in the form of a composite material consisting of a mixture of fine aggregate, coarse aggregate, cement, and water. However, in certain cases, the concrete application is often a problem, especially the lack of a minimal amount of coarse aggregate material, increasing material prices. Recycled concrete aggregate (RCA) is an embodiment of concrete composed of recycled materials. Recycled material is obtained from fragments or remnants of the demolition of unused concrete. The method used to make concrete from the constituent materials using concrete waste as coarse aggregate per the rules of science is experimental. The tests are the aggregate moisture content test, the mud content test, the coarse aggregate abrasion test, the slump test, and the concrete compressive strength test at 28 days of treatment. The compressive strength results showed that the normal concrete sample could reach FC 18.53 MPa. The concrete sample using recycled coarse aggregate reached FC 23.79 MPa, so using recycled materials for manufacturing concrete can achieve the planned target

Beton merupakan media konstruksi bangunan yang memiliki sifat kuat terhadap tekan dan terbentuk dari campuran agregat kasar (koral), agregat halus (pasir), semen dan air. Keunggulan dari beton adalah memiliki sifat mekanik yang kuat, daya tahan yang sangat baik, serta memiliki struktur mikro yang padat. Dibalik kunggulan-keunggulan beton, beton juga tetap memiliki kekurangan. Salah satu kekurangan adalah pada kebutuhan dalam memperoleh material. Hal tersebut disebabkan oleh eksploitasi bahan material secara berlebih sesuai dengan maraknya penggunaan beton hingga jangkauan dalam memperoleh material menjadi lebih sulit dan mahal. Dalam rekayasa kebutuhan material yang digunakan dalam penelitian pembuatan beton kali ini adalah dengan melakukan kombinasi serat baja pada bahan baku pembuatan beton. Metode yang digunakan dalam penelitian beton kali ini adalah dengan menggunakan metode kombinasi serat baja menjadi campuran bahan baku beton, Dari penelitian ini didapat kesimpulan bahwa harga pembuatan beton normal lebih murah dibanding beton dengan modifikasi serat baja. Perbandingan untuk pembuatan 3 buah pada beton normal menganggarkan Rp.151.415,00 sedangkan pada beton dengan penambahan serat baja menghabiskan anggaran biaya senilai Rp. 155.312,00. Selisih harga pada pembuatan beton adalah Rp.3.897,00. Pada hasil uji kuat tekan beton kombinasi serat baja nilai teringgi adalah 11,87 Mpa dengan nilai rata – rata 10,58 Mpa, sehingga mampu memenuhi target rencana job mix formula 10,38 Mpa.
