The soil in Cintaraja Village is known to have clay soil characteristics, in the rainy season the soil will expand, while in the dry season the soil will experience shrinkage which can be seen visually, the soil is dry and cracked. The solution to this problem is to stabilize the soil with chemicals. In this study the chemicals used were gypsum and red brick powder. The percentage levels of gypsum and red brick powder used in this study were 7%, 14% and 21%. This research was conducted to determine the physical and mechanical properties of clay in Cintaraja Village, to determine the effect of a mixture of gypsum and red brick powder, and to analyze the cost of stabilizers. The tests carried out in this study were sieving analysis, soil water content, soil specific gravity, soil unit weight, atterberg limit, and soil shear strength. The results of the study showed that the soil in Cintaraja Village was clay soil with an LL value of 58.12%, IP 27.16%, cohesion value of 18.69%, and soil shear angle value of 40.91%. The added stabilizer has an effect on clay, where the addition of gypsum and red brick powder can decrease and increase the liquid limit value, plasticity index value, shear angle and clay cohesion value. The cost of the stabilizer on the addition of 21% gypsum is Rp. 605,682 /m and 7% red brick powder of Rp. 77.653 /m.</p> <p><strong><em>Keywords — </em></strong><em>Stabilization, Clay Soil, Gypsum, Red brick powder, Direct Shear.</em></p> <p><strong>Ab</strong><strong>s</strong><strong>tr</strong><strong>a</strong><strong>k</strong>— Tanah lempung merupakan salah satu jenis tanah yang memiliki karakteristik kembang susut yang besar dan daya dukung yang rendah.

These fluctuations cause geotechnical construction issues, such as cracks on road surfaces. To address these surface cracks, various studies have been conducted, one of which is the effort to improve soil characteristics through the soil stabilization process. Therefore, this research analyzes the physical and mechanical properties of the original soil, measures, and compares the CBR values of the original soil before and after stabilization with alternative mixtures of coconut husk ash and shell powder. This study employs an experimental approach, involving several tests, including physical property tests such as moisture content, bulk density, soil specific gravity, sieve analysis, Atterbeg Limits, and mechanical property tests such as compaction (Proctor) and CBR (California Bearing Ratio). The results of the physical property tests on the original soil from Kp. Cimacan, Desa Cintaraja, Kec. Singaparna, Kab. Tasikmalaya show that the soil has a moisture content of 51.9%, bulk density of 1.52 g/cm³, and specific gravity of 2.59. This soil is classified as organic clay. The mechanical property tests show that the CBR value of the original soil is 4.75% for unsoaked and 3.75% for soaked. The addition of coconut husk ash increases the unsoaked CBR value to 6.45%, and the soaked CBR to 6.21%. The addition of shell powder increases the unsoaked CBR value to 9.2%, and the soaked CBR to 7.45%.</p> <p><strong>Keywords — </strong>Clay Soil, Coconut Coir Ash, and Shell Powder.</p> <p><strong>Abstrak— </strong>Tanah lempung memiliki plastisitas tinggi serta kohesifitas yang besar berakibat fluktuasi kembang susut yang relatif besar.
