The use of the preloading method, which combined with PVD, is now a common method of soil improvement that proved effective in increasing bearing capacity and reducing settlement on soft soil ground types like former rice fields. In order to reach an optimum effectiveness of soil improvement, an evaluation of the settlement should be done by reviewing the performance of soil improvement along with geotechnical instruments installed in the field. In this study, the back analysis method is used to determine the soil design parameters that are following the actual conditions in the field. The results obtained from the evaluation of settlement conducted is the difference between settlement calculation theoretically before the improvement of soil with the available field data of monitoring Settlement Plate. An average percentage of 118% was obtained from the calculation. In contrast, an average percentage of 2.87% was obtained as the difference between the final settlement prediction of Asaoka's with actual settlements based on Settlement Plate readings data in the field. The parameters of the soil results from the back analysis gave new values with each of the average of Ch= 0.02936; Cc= 0.27313; kv= 0.00005 m/day; and mv= 0.00064m2/kN. The difference between theoretical settlement recalculated using the soil parameter of the back analysis method with the actual settlement based on monitoring of Settlement Plate gave an average percentage of 12.66%. Metode Preloading yang dikombinasikan dengan PVD merupakan salah satu metode perbaikan tanah yang terbukti efektif dalam meningkatkan daya dukung tanah dan mengurangi settlement pada tanah jenis lunak seperti tanah bekas sawah. Agar perbaikan tanah yang dilakukan memiliki efektifitas optimum, perlu adanya evaluasi terhadap settlement yang terjadi dengan meninjau kinerja perbaikan tanah beserta instrumeninstrumen geoteknik yang terpasang di lapangan. Selain itu, dilakukan Metode Analisa Balik untuk mengetahui parameter desain tanah yang sesuai dengan keadaan sesungguhnya di lapangan. Hasil yang didapatkan dari evaluasi settlement yang dilakukan adalah selisih settlement secara teoritis sebelum adanya perbaikan tanah dengan settlement berdasarkan monitoring Settlement Plate di lapangan dalam persentase rata-rata sebesar 118%, sedangkan selisih antara final settlement prediksi Asaoka dengan settlement akhir berdasarkan monitoring Settlement Plate di lapangan mendapatkan persentase rata-rata sebesar 2,15%. Parameter-parameter tanah hasil dari analisa balik memiliki nilai baru dengan masing-masing rata-rata sebesar Ch= 0,02936; Cc= 0,27313; kv= 0,00005 m/hari; dan mv= 0,00064m2 /kN. Sedangkan untuk selisih antara settlement secara teoritis yang dihitung kembali menggunakan parameter tanah hasil analisa balik dengan settlement aktual berdasarkan data bacaan Settlement Plate mendapatkan persentase rata-rata sebesar 12,66%.

In some cases, basement wall work still often occurs as a construction failure with a variety of causes. One of them is a basement construction project for an apartment and mall in Grand Dharmahusada Lagoon. The first plan of the basement wall didn’t strong enough to resist a lateral movement of the soil. The previous studies have been carried out by redesigning the retaining wall using a diaphragm wall and ground anchor as a support system. The results are obtained that the use of diaphragm walls can decrease the value of displacement that occurs on the wall. However, previous studies have only conducted a review of the diaphragm wall thickness. This study adds several numbers of anchors as research variables to find effective and efficient combinations. This study compares the effect of diaphragm wall dimensions with a different number of anchors on the deformation value and safety factor. Based on the results of the study, a wall thickness of 1.75 m with a depth of 33 m using 3 anchors a deformation occurred are 3.63 m while using 4 anchors a deformation occurred are 2.37 m. The difference in deformation is 1.26 m. Because the value of deformation was still large, it carried out a re-design for the anchor position, and diaphragm wall dimension with the same number of anchors, and the deformation results were reduced to 15.81 cm with a safety factor of 1.3. ABSTRAK Pada beberapa kasus, pekerjaan dinding basement masih sering mengalami kegagalan konstruksi dengan berbagai macam penyebab. Salah satu diantaranya pada proyek pekerjaan dinding basement apartemen dan mall Grand Dharmahusada Lagoon. Dinding basement yang direncanakan diawal ternyata tidak cukup kuat untuk menahan pergerakan lateral tanah. Telah dilakukan pada penelitian sebelumnya dengan merencanakan ulang dinding penahan tanah menggunakan dinding diafragma dan sistem penunjang angkur tanah. Kemudian didapatkan hasil yaitu penggunaan dinding diafragma mampu memperkecil displacement yang terjadi pada dinding. Namun penelitian sebelumnya hanya melakukan tinjauan pada ketebalan dinding diafragma. Penelitian ini menambahkan jumlah angkur sebagai variabel penelitian untuk mencari kombinasi yang efektif dan efisien. Penelitian ini membandingkan pengaruh penggunaan dimensi dinding diafragma dengan jumlah angkur yang berbeda terhadap nilai deformasi dan faktor keamanan. Berdasarkan hasil analisa menggunakan PLAXIS V8.6, pada ketebalan dinding 1,75 m dengan kedalaman 33 m menggunakan 3 angkur terjadi deformasi sebesar 3,63 m sedangkan dengan penggunaan 4 angkur terjadi deformasi 2,37 m. Selisih deformasi yang terjadi sebesar 1,26 m. Direncanakan ulang untuk penempatan angkur, dimensi dinding pada jumlah angkur yang sama maka didapatkan hasil deformasi berkurang hingga 15,81 cm dengan faktor keamanan 1,3.

CBR (California Bearing Ratio) data is used to find out the level of subgrade density, so that a safe pavement thickness can be planned. The calculation of the CBR (California Bearing Ratio) can be done by testing CBR laboratory and DCP. CBR results have a high effect on the surface layer, so that the layer becomes thinner. This condition, if converted to the working price, will be more affordable and efficient. Therefore, this study aims to compare the results of laboratory CBR and Field Cbr (Dcp) to the thickness of flexible pavements in the Development of Trans South-South Java Road Project (TRSS) Lot 8 Jarit - Puger. The method used is Bina Marga Pd T-01-2002-B. Secondary data obtained by weigh bridges and service providers, namely PT. Brantas Abipraya (Persero).

A Landslide is the movement of soil mass or rock constituents down the slope due to disturbance of soil stability. One of the factors that affect soil stability is the rainy season as happened in Sumberwuluh Village, Candipuro District, Lumajang Regency. The alternative used to stabilize the slope is by changing the slope geometry, then adding geoframe reinforcement. This study aims to determine the value of the factor of safety (SF) of unreinforced slopes, after changing the slope geometry, and after being given geoframe reinforcement. The method used in analyzing slope stability is the Ordinary/Fellenius method. The results of the calculation of slope stability without reinforcement using the Rocscience Slide software obtained a SF of 0.719, while the manual calculation obtained a SF of 0.7191. The two values of the safety factor are less than 1.25, which means that landslides often occur. The results of the calculation of slope stability after changing the geometry of the slopes obtained a SF of 0.828 where the value is less than 1.25 which means that landslides often occur. The slopes that have been changed geometry are added with geoframe reinforcement. The results of the calculation of slope stability using geoframe reinforcement obtained a SF of 1.315 where the value is more than 1.25 which means that landslides are rare or slope in a safe condition.

The landslide occurred on the slopes of the Gandong Magetan River. The location of the river in the middle of the city caused landslides to almost reach people's homes. Efforts should to be made to improve slope stability so that it is safe against landslides. Slope stability analysis uses the LEM (Limit Equilibrium Method) with the Geoslope program. The results of the analysis of the slope stability of the existing conditions get the value of the safety factor of 0.379. Alternative reinforcement that is planned is the manufacture of counterweight slopes. Planning of counterweight slope embankment as many as 4 levels with a height of 3 m each level. The results of the counterweight slope stability analysis get a safety factor value of 0.507. The critical area is at the top of the slope so that soil nailing reinforcement is added. The results of the counterweight slope stability analysis with soil nailing and gabion reinforcement obtained a safety factor value of 1.507. So that the slope reinforcement plan is safe against landslides.

Infrastructure improvements are needed to accelerate the pace of the economy. The impact of Covid-19 has recently reduced the quality of infrastructure due to reduced community mobility. To improve infrastructure, especially roads, proper planning is needed according to existing regulations. State apparatus at the local level is expected to be able to prepare good road planning. The use of concrete roads is suitable for some areas that are far from the city because of low maintenance costs. In the Wuluhan District, there are several obstacles so that this service is expected to increase knowledge about concrete road planning. The output of this service is an understanding of concrete road planning in accordance with PU Bina Marga regulations. Keywords: Construction, Technical, Road, Concrete, Wuluhan, Jember.

The Santer Riverbank which is located in Panggul Melati Hamlet, Kepanjen Village, Gumukmas District, Jember Regency, East Java is still used by the community for agricultural land. This research was conducted to create safe agricultural land for the community. Landslides on this riverbank often occur because it is located on the edge of the river and has a steep slope. In the observation in 2022, there is a collapsed riverbank approximately 20 meters in front of the river embankment. To prevent a longer landslide area, the slopes on the river border are optimized so that residents can still use the land safely. The selected reinforcement is made based on the geometric conditions and the results of the SF value from modeling the existing conditions using the Geostudio program. Appropriate reinforcement based on geometric conditions and SF values is a balancing method. close to the counterweight method, the geometric conditions are more optimal with the SF value increasing from 1.099 to 1.623
