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.

Road construction on expansive soil faces many problems such as deflection, longitudinal cracks, circular cracks and spreading cracks in road construction due to the large nature of swelling and shrinkage. This study aims to identify changes in the mineralogy microstructure and chemical properties of the soil in chemically corrected expansive soils so that solutions for expansive soil improvement are obtained by utilizing local materials based on industrial waste, namely Fly ash and Waste Foundry Sand. The research method is in the form of laboratory experiments, namely Structure Electron Microscope and XRD tests on native soil and soil stabilized with Fly ash and Waste Foundry Sand to analyze mineral structure and chemical changes. The results of the analysis found that the effect of the two types of additives on expansive soils was descriptively significant. The addition of fly ash and WFS to the soil makes the pores and cracks filled with fly ash particles and some form of hydration. After the addition of Fly ash and WFS, ion exchange and pozzolanic reactions from fly ash occur to make the flake and flocculant structure of the soil cement into a crystal or block structure, thereby increasing the compactness and integrity of the soil sample.

Abstract   This activity aims to provide services and information to the manager of the Nuurus Sa'ada mosque in assessing the compressive strength of the concrete at the renovation of the Nurus Sa'ada Tangerang mosque as a quality control for the building being renovated. The method of activity is to do the Hammer test at several points in the Mushola area such as the floor plate and column structures. This activity involved lecturers in Universitas Islam 45, Faculty of Engineering, Universitas Islam 45 Civil Engineering laboratory assistants, and the manager of the Nurus Sa'ada mosque, as well as renovation implementers.   Key words: Hammer Test, Mushola Renovation, Compressive Strength, Mosque   Abstrak   Kegiatan ini bertujuan untuk memberikan pelayanan dan informasi kepada pengelola mushola Nuurus Sa’ada untuk menilai kuat tekan beton pada renovasi mushola Nurus Sa’ada Tangerang sebagai kontrol kualitas bangunan yang sedang direnovasi.

ABSTRAKSeiring dengan bertambahnya usia bangunan maka ada penurunan dari kapasitas struktur sehingga dimungkinkan lendutan dan retak pada komponen struktur bertambah besar. Begitu pula permasalahan lendutan pelat lantai yang terjadi pada gedung Rektorat Universitas Islam "45" Bekasi menyebabkan pengguna bangunan menjadi tidak nyaman. Agar besar lendutan yang terjadi tidak bertambah parah maka perlu adanya solusi perbaikan. Pemecahan permasalahan yang terjadi dilakukan melalui survei lapangan untuk mengetahui besarnya lendutan yang terjadi, melakukan analisis kekuatan pelat dalam menahan beban dengan program SAP2000 berdasarkan peraturan SNI 03-2847-2002 dan menghitung perkuatan struktur lentur yang diperlukan oleh pelat dan balok berdasarkan metode LRFD yang berpedoman pada peraturan SNI 03-1729-2002. Hasil perhitungan terdapat 5 lokasi pelat yang mengalami penurunan dengan besar masingmasing pelat yaitu 5,3 cm; 6,8 cm; 8 cm; 6,9 cm dan 10,9 cm. Kemudian besar beban maksimal yang masih dapat bekerja untuk pelat II yaitu 350 kg, untuk pelat IV yaitu 300 kg, untuk pelat V yaitu < 240 kg. Jenis dan dimensi perkuatan yang digunakan pada pelat adalah profil baja WF 125 x 60 BJ 37, sedangkan pada balok yaitu profil baja WF 150 x 150 BJ 37. University "45" Bekasi causes discomfort to the building users. In order for the deflection does not get worse the need for repair solutions is a must. Problem solving is done through a field survey to determine the size of the deflection, analyze the strength of the plate in holding the load by using SAP2000 program based on the SNI 03-2847-2002 regulation and calculate the reinforcement of the bending structure required by the plate and beam based on the LRFD method based on the regulations SNI 03-1729-2002. Based on calculation results, there are 5 plate location that decreasing its structural capacity with each size of the plate are 5.3 cm; 6.8 cm; 8 cm; 6.9 cm and 10.9 cm. The maximum load that can still work for plate II is 350 kg, for plate IV is 300 kg, for plate V is <240 kg. Type and dimensions of a reinforcement used on the plate is a WF 125 x 60 BJ 37 steel profile, while on the beam is WF 150 x 150 BJ 37 steel profile. ABSTRACT Along with the age of a building increased then there is a decrease in the structure capacity so that deflection and crack on a structural components became larger. So does the floor plates deflection problem that occured in the Rectorate building of Islamic
