Analisis Kapasitas Saluran Daerah Irigasi Lubuk Buntak Kecamatan Dempo Selatan Kota Pagar Alam
Full text linkBuilders in this irrigation area are a great opportunity to improve the economy of the community Lubuk Buntak. In order to improve and maintain agricultural production of food crops, the Pagar Alam City Government has until now built irrigation facilities and infrastructure both for the construction of new irrigation or rehabilitation in order to support the planned food security program. Irrigation channels located in the Lubuk Buntak irrigation area during the rainy season the water found on the irrigation canal has exceeded the capacity of the irrigation channel so that the irrigation can not work optimally, due to the high rainfall that occurs Thus the irrigation of Lubuk Buntak City Pagaralam irrigation area needs to be analyzed for the rainfall that occurs, in order to determine the ideal irrigation canal design and in accordance with the magnitude of the planned flood discharge, so that the planned irigassi channel works optimally. The purpose of this survey is about Rainfall Analysis, Calculation of planned flood discharge, Irrigation Channel Dimension, in this thesis using five Smirnov-Kolmogorov matching medotas from the calculation of the suitability of the method used is the gumbel method because the maximum difference (Dmax) -4, 70 <from Critical Value 41% (0.41), and analyze flowrate, so that the Irrigation Channel remains optimal for water resources can be utilized according to its designation, based on the parameters obtained. Next, identify the irrigation channel, calculate the intensity of rainfall, determine the flood discharge and the last design the channel dimensions for the area. The research carried out with a land area of 50 ha was obtained by the value of the intensity of the 50-year return rainfall of 530.76 m3 / sec, the planned flood return period of 50 years was 1.48 m3 / sec and the design of the channel dimension was (h) = 1, 42 m (B) = 1.40 m, (wf) = 0.29 m, and (TMA) = 1.17
Direct numerical simulation of 'short' laminar separation bubbles with turbulent reattachment
Full text linkDirect numerical simulation of the incompressible Navier–Stokes equations is used to study flows where laminar boundary-layer separation is followed by turbulent reattachment forming a closed region known as a laminar separation bubble. In the simulations a laminar boundary layer is forced to separate by the action of a suction profile applied as the upper boundary condition. The separated shear layer undergoes transition via oblique modes and [Lambda]-vortex-induced breakdown and reattaches as turbulent flow, slowly recovering to an equilibrium turbulent boundary layer. Compared with classical experiments the computed bubbles may be classified as ‘short’, as the external potential flow is only affected in the immediate vicinity of the bubble. Near reattachment budgets of turbulence kinetic energy are dominated by turbulence events away from the wall. Characteristics of near-wall turbulence only develop several bubble lengths downstream of reattachment. Comparisons are made with two-dimensional simulations which fail to capture many of the detailed features of the full three-dimensional simulations. Stability characteristics of mean flow profiles are computed in the separated flow region for a family of velocity profiles generated using simulation data. Absolute instability is shown to require reverse flows of the order of 15–20%. The three-dimensional bubbles with turbulent reattachment have maximum reverse flows of less than 8% and it is concluded that for these bubbles the basic instability is convective in nature

Analisa Struktur Atas (Upper Structure) Jembatan Kaburejo Kota Pagar Alam
Full text linkOne means of transportation is a bridge that connects an area due to obstacles or road divides. There are many bridges in the City of Pagar Alam, one of which is in the Kaburejo area, the bridge in this area is less feasible for vehicles because it has a smaller bridge span than the highway. The purpose of this study is to do an upper structure re-design with a 6 m wide bridge and a 15 m long bridge span made with reinforced concrete construction that has a reinforced longitudinal beam which is an integral part of the vehicle floor so that it can meet the maximum traffic capacity. Bridge planning analysis is carried out on the bridge structure which includes the backrest, sidewalk floor, floor plate and main beam
Model Promosi Wisata Alam Puncak Kuik
Full text linkKabupaten Ponorogo merupakan salah satu kabupaten di Jawa Timur yang memiliki banyak potensial yang dapat dikembangkan menjadi aktivitas wisata Wisata alam Puncak Kuik merupakan salah satu wisata alam rintisan yang ada di Kabupaten Ponorogo, tepatnya Desa Gajah, Kecamatan Sambit. Pegunungan ini memiliki ketinggian puncak kurang lebih sampai 1200 mdpl (meter di atas permukaan laut). Wisata alam ini berupa pegunungan dan lereng bebatuan. Lahan yang digunakan sebagai objek wisata alam ini merupakan tanah milik perhutani, kemudian dikelola oleh Pemerintah Desa Gajah sebagai tempat wisata alam. Pemerintah Desa Gajah membentuk Kelompok Sadar Wisata (POKDARWIS) untuk mengelola dan mengembangkan wisata alam Puncak Kuik. Dari lokasi Puncak Kuik ini, pengunjung dapat melihat keindahan panorama Kota Ponorogo. Selain itu, pengunjung juga dapat menikmati suasana pegunungan yang sejuk dan asri. Berikut denah lokasi wisata alam Puncak Kuik. Kendala yang menghambat proses pengelolaan wisata alam Puncak Kuik diantaranya adalah perizinan lokasi wisata, akses transportasi yang sulit dijangkau, fasilitas dan kesadaran masyarakat serta promosi wisata melalui media sosial. Dalam pengelolaan objek wisata Puncak Kuik, pemerintah Desa Gajah membentuk Kelompok Sadar Wisata (POKDARWIS) yang beranggotakan pemuda atau karangtaruna desa. POKDARWIS sebagai pengelola wisata alam Puncak Kuik bertanggung jawab dalam menjalankan aktivitas pemeliharaan dan pengembangan lokasi wisata. Adapun dukungan dari Pemerintah Desa adalah dengan melakukan pemberdayaan pada anggota POKDARWIS mengenai tata pengelolaan wisata alam Puncak Kuik
Konsep wakaf jamin kesejahteraan alam sekitar
No full textIslam adalah agama 'rahmatan lil 'alamin' yang bermaksud kesejahteraan bagi seluruh alam. Terjemahan ungkapan itu boleh direalisasikan dalam pelbagai cara dari aspek kecil seperti membuang sampah di jalanan sehingga kepada aspek yang besar.
Ia termasuk memastikan kehidupan manusia dinaungi sistem pemerintahan yang adil, ekonomi mapan dan kekayaan dihasilkan melalui empayar perniagaan yang mengambil kira cukai serta zakat
Kalimah berguna dalam tiga alam
Full text linkKALIMAH itu bukan kalimah biasa. Ia menjadi punca penciptaan semua makhluk terutama manusia dan jin. Ia adalah kalimah pengiktirafan bahawa ‘tiada tuhan yang selayaknya disembah melainkan Allah’.
Kalimah ini sudah diakui oleh manusia ketika mereka dikumpulkan Allah dalam alam ‘arwah lama’ sebelum mereka lahir ke dunia ertinya: “Dan (ingatlah wahai Muhammad) ketika Tuhanmu mengeluarkan zuriat anak Adam (turun-temurun) daripada (tulang) belakang mereka, dan Dia jadikan mereka saksi terhadap diri mereka sendiri, (sambil Dia bertanya dengan firman-Nya): “Bukankah aku Tuhan kamu?” Mereka semua menjawab: “Benar (Engkaulah Tuhan kami), kami menjadi saksi”. Yang demikian supaya kamu tidak berkata pada hari kiamat kelak: “Sesungguhnya kami adalah lalai (tidak diberi peringatan) tentang (hakikat tauhid) ini.” (al-A’raf 7:172).
