Land is a very complex material. We must improve physical and mechanical properties of the soil if it is found that the soil does not meet the technical requirements to be used to support buildings or roads. Therefore, before using it as a support building, the ground must be stabilized. One method for stabilizing the soil is chemical stabilization as an effort to increase strength, reduce declination, and improving physical and mechanical properties of others. In this study, we use chemical stabilization method to perform a series tests of physical properties and compressive strength test on the land unfettered native land and soil soaked with a chemical solution between the Na2C03, CaCl2, KOH, and Na2Si03 (Water-glass) as much as 2 g / liter for 24 hours at the Laboratory of Soil Mechanics of Unisma Bekasi and Soil Mechanics Laboratory of the Public Works Department of Irrigation at Central Jakarta Physical properties of a series of tests concluded that the soil has a high development and graded poorly because it does not meet the criteria for the coefficient of gradation and uniformity coefficient. Land, including the type CH (inorganic clay with high plasticity), and within the category of very soft clay and a bit sensitive. The test results unleashed a strong compressive (qu), the highest value obtained on clay soaked in a solution ofpotassium hydroxide (KOH) 2 g/liter is equal to 84.21% of the value ofquof original land

Pabrik PT. Hitachi Construction Machinery Indonesia telah mengalami banjir hampir setiap tahun. Banjir yang terjadi pabrik PT. Hitachi Construction Machinery Indonesia disebabkan karena area pabrik memiliki elevasi yang lebih rendah dibandingkan area sekitar. Menyadari bahwa lahan resapan di sekitar area pabrik semakin berkurang sehingga kemungkinan jumlah debit banjir bertambah semakin membahayakan area pabrik maka perlu dilakukan analisa kapasitas daya tampung sistem drainase yang ada dengan perkiraan debit banjir rencana. Dilakukan perhitungan kapasitas dari sistem drainase existing dan kapasitas dari sistem drainase yang baru. Data curah hujan yang digunakan adalah data curah hujan maksimum tahunan. Metode analisis curah hujan menggunakan metode gumbel. Perhitungan debit rencana menggunakan metode rasional. Kemudian dilakukan perhitungan kapasitas saluran drainase existing dan redesign untuk saluran-saluran juga kolam yang kapasitasnya tidak memenuhi. Kapasitas sistem drainase sesuai dengan debit rencana. Sesuai hasil penelitian debit existing sebesar 1,185 m³/s mampu menampung hingga debit rencana periode ulang 100 tahun sebesar 0,54 m³/s. Beberapa saluran sekunder harus dimodifikasi dimensinya agar tidak terjadi genangan di area yang memiliki elevasi yang rendah yaitu pada ditch 14, ditch 15 dan ditch 34. Kolam retensi existing tidak dapat menampung debit banjir maka perlu dibuatkan kolam retensi yang baru. Pada periode ulang 100 tahun volume yang tidak tertampung sebesar 45.148,27 m³ dan membutuhkan ground water tank dengan luas permukaan 10.085,93 m² dengan tinggi 4,48 m.

The Swamp Irrigation Area (DIR) of Dadahup District is a former Peat Land Development (PLG) with an area of around 21,226 Ha. The water management system at DIR Dadahup utilizes changes in sea tides as a source of water to the land and drainage to drain water out of the land. However, in its implementation, DIR Dadahup experienced several problems such as flooding during the rainy season and experiencing drought during the dry season. These conditions indicate the need for land management and water management systems to overcome existing problems. The purpose of this study was to optimize the water management system for irrigation by optimizing the functions and benefits of swamp land in Dadahup, Kapuas Regency, Central Kalimantan Province. Optimization of the water system is carried out by modeling using the HEC-RAS program. Flow modeling with HEC-RAS in irrigation canals can be simulated into two scenarios, namely scenarios using gates and scenarios with doors and pumps for the rainy and dry seasons. Based on the results of the modeling analysis that has been carried out, the surface elevation during the dry season is in the range of +0.06 ms/d + 0.77 m, which is below the average land elevation (+0.8 m MSL). experience drought because the water in the canals cannot irrigate the land. The water level during the rainy season is in the range of +0.82 ms/d +1.53 m, which is above the average land elevation. It can be concluded that irrigation canals cannot accommodate the overflow of water that occurs at the planned discharge so that the land is flooded. The scenario model is suitable for the Dadahup DIR land use, namely with the door and pump scenario, the water level elevation for the dry season and the rainy season can reach the target of +1.0 m, then the water level elevation for the rainy season can also reach the target of +0, 7m.
