The Miu basin is one of the watersheds located in Sigi District, Central Sulawesi province with an area of 10,471,71 km2. In the last few years, Miu basin frequently got flood disaster and sediment. The change of watershed response to rain due to land use change is pointed to be the cause of frequent floods. It is necessary to overcome the frequent flooding in Miu basin by conducting hydrological analysis to determine the peak discharge change due to land use change. In this study, the analysis of the area of rain with Polygon Thiessen Method was conducted with the help of ArcGIS 10.3 software. ArcGIS 10.3 software is also used to analyze land use change. The process of diversing the rain into a stream by calculating the effective rainfall (Peff) using the Soil Conservation Service-Curve Number (SCS-CN) Method. For Design Flood is calculated by the Nakayasu HSS Method. The research shows that the value of Curve Number as the determinant variable of land function change at Miu basin of 2003, 2009 and 2014 did not experience significant change. The decrease of flood peak discharge by HSS Nakayasu method in 2003, 2009 and 2014 respectively 525 m3 / sec, 366,4 m3 / second and 154,3 m3 / sec. The decrease in peak flood discharge is due to the fact that in addition to the non-significant land use change, the area rainfall as the input in the flood analysis of the designs of those years decreased from 2003 to 2014.Â

Peat soils have a high compressibily and low bearing capacity. This unfavourable characteristic might cause differential settlement dan failure of the construction, so that the appropriate improvement method is required to overcome this problem.Peat soil improvement method that commonly used is mechanically dan chemically soil improvement method. In this research, the peat soil reinforced with geotextile was conducted in order to find its influence in increasing the bearing capacity.Also, peat land are generally located in the area with shallow water level. In this research shallow foundation reinforced with geotextile with variations ground water level was conducted to determine its effect in improving the bearing capacity. The variation of layer number of reinforcement (N) used was N= 3, with width 2B reinforcement, where the variations of ground water level are z = 0 cm, z = 5 cm and z = 10 cm where B is foundation width and z are the distance of the ground water level from base of the foundation. Result of modeling in the laboratory shows that the insertion of geotextile material in the peat soil can increase its soil bearing capacity. The increasing of ultimate bearing capacity (qu) tends to be higher for reinforced soil with no ground water level compared to soil with ground water level.The closer ground water level to foundation base the smaller the bearing capacity either with or without reinforcement. The highest value of bearing capacity was obtained in reinforced peat soil with no water level that is 8,6 kN/m2 or the it increase as much of 178,1% compared to unreinforced peat soil with no water level. Bearing capacity ratio (BCR) has also increase as of as 2,78 in with the reinforcement without water level compared to condition without reinforcement and without water level.

Di Indonesia ada empat periode berlakunya peraturan tentang bagunan gedung yaitu : GBV & PBI-55, (2) PBI-71, (3) PPTGIUG-83 & SNI Tata Cara Perencanaan Bangunan Gedung Beton Bertulang tahun (4) SNI Perencanaan Bangunan Beton Bertulang 2002 & SNI Bangunan Beton Bertulang Tahan Gempa tahun 2002, keempatnya mempunyai beban rencana gempa dan pendetailan tulangan yang berbeda-beda. Seiring dengan perubahan peta zonasi gempa yaitu peta zona gempa tahun 2010, yang mana Kota Palu berada pada daerah gempa dengan intensitas sangat tinggi sehingga diperlukan upaya evaluasi dan pengurangan kerentanan akibat gempa sehingga kerugian material dan korban jiwa dapat dikurangi. Langkah penting yang dibutuhkan adalah melakukan evaluasi terhadap bangunan yang telah berdiri dan melakukan perkuatan dan perbaikan untuk gedung yang setelah dilakukan evaluasi ternyata memiliki kapasitas beban gempa lebih kecil dari kapasitas beban sesuai peraturan terbaru. Telah banyak bangunan yang gagal dan hancur akibat gempa, dan telah banyak pula metode yang dikembangkan untuk mengurangi kerusakan akibat gempa tersebut. Sehingga sangat dibutuhkan pengembangan metode perkuatan dan perbaikan struktur bangunan untuk mengantisipasi kerusakan bangunan pada saat terlanda gempa. Titik-titik lemah bangunan yang merupakan titik-titik kegagalan bangunan akibat beban gempa, antara lain : join fondasi-kolom, join balok-kolom, dinding pasangan dan system struktur atap. Elemen-elemen tersebut sangat membutuhkan perkuatan sebelum terjadi gempa serta pendetailan penulangan yang akurat. Perkuatan dan perbaikan elemen struktur bangunan yang telah dikembangkan antara lain : perbaikan kerusakan dinding pasangan dengan metode plesteran yang diperkuat kawat, melapisi elemen strutur bangunan dengan lapisan betob baru, penambahan tulangan dan lapisan beton dengan metode shotcrete pada elemen balok, kolom dan pelatdan perbaikan retak dengan bahan epoxy recin pada elemen pelat

Bridge is one of the most important transportation infrastructures that joining two side of highway thus the bridge is highly needed. To design a bridge geotechnical and hydrological data is crucial as well as characteristic of the river. In the case if a bridge were designed without acurately determine the 50 year return period of flood, then the bridge possibly are not save against real flood that may occur. Thus the abutment has to be redesign and retrofitted. Redesign is important to fullfill requirement of high of free space superstructure if the maximum flood occur. Redesign conducted by adding 1,6 m high of the abutment. Controlling stabilities of the abutment i.e: shear and overturning were done. Retrofitting was applied by adding longitudinal and transversal reinforcement with the same dimension and space especially at the joint of transversal reinforcement, transversal reinforcement space reduced to half of its normal space. Longitudinal reinforcement applied was D19-150 and the transversal reinforcement was ᴓ12-100. To connect the fresh concrete and existing concrete applied material were epoxy resin based produced by PT. SIKA Nusa Pratama SIKADUR®732.

Penelitian ini dilakukan untuk mengetahui proses erosi-sedimentasi, dan perubahan garis pantai serta morfologi Pantai Rerang, Kab. Donggala. Model perubahan garis pantai didasarkan pada persamaan kotinuitas sediment. Pantai dibagi menjadi sejumlah sel (ruas). Pada setiap sel ditinjau angkutan sediment yang masuk dan keluar. Sesuai dengan hokum kekekalan massa, jumlah laju aliran massa netto didalam sel adalah sama denga laju perubahan massa di dalam tiap satuan waktu. Perubahan garis pantai tersebut dapat diprediksi dengan membuat model matematik yang didasarkan pada imbangan sediment pantai pada daerah pantai yang ditinjau. Prinsip tersebut digunakan dalam meyusun model matematik perubahan garis pantai dan dikembangkan menjadi sebuah perangkat lunak yang dikenal dengan nama GENESIS. Program GENESIS menerapkan “one-line simulationâ€, dimana batas antar laut dan darat di pantai digambarkan sebagai suatu bidang yang tegak. Perangkat lunak ini diaplikasikan untuk memodelkan perubahan garis Pantai Rerang Kabupaten Donggala

The placement of median opening (U Turn) and the distance of inter median opening at several road in Palu city were indicated that it does not meet technical requirement so it can put the road user in dangerous situation which when the traffic flowing on the road grow higher then the risk of traffic accident will rise too. Moreover, the placement of median opening was indicated as an access road where as a place for specific activity beside the road. The existence of Garuda-Abd. Rahman Saleh as a T intersection also made an impact to the degree of saturation of certain road segment. The method that used to solve this study is based on the survey to collect the primary and secondary data MKJI 97 and median standard design analysis. The result shows that all of the placement median opening at several urban road links was not appropriate to the requirement standard then it needs reposition or any repairmen.
