“…(a) Observation of the First Month's Settlement, (b) Observation of the ThirdMonth's Decline The actual settlement in the field does not exceed the planned value. This shows the safety of the structure[24][25]. Conformity of settlement values with plan limits and structural safety standards indicates success and reduces the possibility of problems occurring due to settlement[26].…”

Kediri has been named the Most Sustainable City. To support this, Kadiri University also contributed by building lecture buildings. In its implementation, there is a difference in the depth of the foundation from the initial plan. This causes the need for evaluation to ensure the safety of the building structure. This research aims to identify (Cone Penetration Test) CPT distances, depth differences, negative skin friction, settlement, and empirical bearing capacity calculations on the safety of building structures on sandy soil. The direct observation method was used to obtain data. The analysis includes a comparison of depth, negative skin friction values, settlement, and bearing capacity. The research results show that the average CPT distance is 18.22 m, which can result in inaccurate CPT data because differences in soil structure can occur. A depth difference of 22% from the plan can be considered safe for the structure. This is validated by a field settlement of 2 mm lower than the maximum settlement limit and a Negative skin friction value of 0, indicating no additional settlement. These parameters indicate that the structure is safe. The modified Meyerhoff and Trofimankove methods are suitable for planning foundations with sandy soil because they can meet the load received. This research can add empirical evidence in evaluating structural safety for different depths of foundation planning and implementation in sandy soil-based projects, as well as reducing the potential risk of structural failure in the long term.

Kalimantan Timur merupakan salah satu daerah penghasil batubara di Indonesia. Tetapi, terdapat masalah umum pada pembangunan pertambangan di daerah Kalimantan Timur berupa adanya lapisan tanah lunak pada sebagian besar daerah pertambangan yang membuat struktur tanah menjadi tidak stabil sehingga bila tanah dibebani akan merusak tanah dan struktur sekitar. Oleh karena itu, dibutuhkan pemilihan metode perbaikan tanah (baik dari nasional maupun internasional) yang sesuai dengan kondisi lapangan agar tanah dapat digunakan untuk berbagai keperluan pembangunan pertambangan. Salah satu metode perbaikan tanah dapat diandalkan oleh berbagai negara maju adalah metode rigid inclusion. Kelebihan dari metode ini adalah pengerjaannya dapat dilakukan dengan cepat, dapat menahan beban yang besar dengan material yang murah, dan memiliki biaya pengerjaan yang murah. Selain menggunakan rigid inclusion, terdapat alternatif perbaikan tanah berdasarkan metode SNI 8460:2017 yaitu deep mixing. Berdasarkan hasil pengamatan, rigid inclusion tanpa menggunakan geogrid mampu mengurangi deformasi pada daerah radial pad sebesar 84,15%, rigid inclusion tanpa menggunakan geogrid mampu mengurangi deformasi pada daerah radial pad sebesar 84,16%, sedangkan deep cement mixing sebesar 87,04%.

“…Sand is involved in many geotechnical aspects; it could be used in backfilling and as a subbase layer for roads and pavements after improving its properties instead of crushed stone [5][6][7][8][9][10]. The utilization of by products in improving sand geotechnical and bearing properties is of big benefit for any country from the environmental and economical point of view [11][12][13][14][15][16].…”

Effective use of natural materials and industrial by products has a direct impact on economy, sustainable environment, and waste management. Poorly graded desert sand (SP) is widely observed in sand dunes and sand seas. Studies were performed to get beneficial use of cement kiln dust (CKD) in soil improvement. But there is a lack of information concerning using of CKD as an improving material for poorly graded sand with the aid of salt water. Salt water is widely available in Egypt from seas and some deep wells, using it will help in saving drink water which suffers from shortage in many countries. The aim of this research is to study the possibility of improving SP using CKD and salt water to be used in backfilling work and subbase layers of roads and pavements. Mixtures of poorly graded sand and various CKD ratios (10%, 20% and 30%) were classified and tested using grain size distribution, compaction, shear strength and California bearing tests. The results were compared with potable water. The results show that adding CKD improves the characteristic properties of SP even with salt water. The study enhances the using of 20% CKD with optimum water content of 9.12% of salt water to have noticeable improvement for SP and to be used efficiently in backfilling and subbase layers.
