An experimental study on angled Trash Screen in open channels
Alexandria Engineering Journal, 2018Co-Authors: Mahmoud Zayed, Anas El Molla, Mohammed SallahAbstract:Abstract Trash Screens are widely employed at entrance of hydraulic structures (culverts, barrages…, etc.), water intakes, and pumping stations to trap flowing debris that could instigate downstream troubles. Traditional Trash Screen (perpendicular-vertical Screen to the flow direction) can cause problems of increasing head loss through it, especially with the blockage ratio. This experimental study presents a concept of an adjusted Screen with circular bars to find a solution for such problem. In this regard, angled Screen models with different angles, blockage ratios, and flow discharges were investigated. The results indicated that the head loss coefficients reduced by reducing the Screen angle, so angled Screen (α

An experimental investigation of head loss through a triangular “V- shaped” Screen
Journal of advanced research, 2017Co-Authors: Mahmoud Zayed, Anas El Molla, Mohammed SallahAbstract:Abstract Common traditional Screens (Screens perpendicular and vertical to the flow direction) face extensive problems with Screen blockage, which can result in adverse hydraulic, environmental, and economic consequences. Experimentally, this paper presents an advanced Trash Screen concept to reduce traditional Screen problems and improve the hydraulic performance of Screens. The traditional Screen is re-developed using a triangular V shape with circular bars in the flow direction. Triangular V-shaped Screen models with different angles, blockage ratios, circular bar designs, and flow discharges were tested in a scaled physical model. The analyses provide promising results. The findings showed that the head loss coefficients were effectively reduced by using the triangular V-shaped Screens with circular bars (α

PERANCANGAN DAN PEMILIHAN KONSEP DESAIN AUTOMATED RIVER CLEANER MACHINE MENGGUNAKAN METODE AHP-TOPSIS
Universitas Telkom S1 Teknik Industri, 2019Co-Authors: Muhammad Imam Ra`isAbstract:Sungai adalah sumber mata air bagi warga yang tinggal di sepanjang tepi sungai. Namun semakin lama sungai mulai tercemar dengan adanya sampah. Sampah pada sungai mulai menumpuk seiring berjalannya waktu, menumpuknya sampah disebabkan karena warga yang masih kurang peduli dengan lingkungan sehingga terjadi banjir dan penyakit. Terdapat beberapa alternatif untuk mengatasi masalah sampah di sungai seperti mengambil menggunakan exafator, memperkerjakan masyarakat untuk membersihkan, dan menggunakan mesin pengangkut sampah. Automated River Claner Machine (Auri Cleaner Machine) adalah sebuah alat pengangkut sampah yang bertujuan untuk menanggulangi masalah banyaknya sampah yang banyak mengalir di sungai. Dalam hal ini penggunaan kombinasi metode AHP-TOPSIS cocok dalam menentukan desain pemilihan suatu desain dari produk. Sehingga mendapatkan konsep H sebagai desain dari mesin pengangkut sampah. Konsep H terdiri dari beberapa komponen seperti Kapal, Trash Screen, Trash Hook, Trash Deliver, dan Trash Container. Kata Kunci: AHP, TOPSIS, Auri Cleaner Machin

PERANCANGAN DESAIN Trash DELIVER UNTUK PROSES PEMINDAHAN SAMPAH PADA AUTOMATED RIVER CLEANER MACHINE MENGGUNAKAN METODE PERANCANGAN PRODUK RASIONAL
Universitas Telkom S1 Teknik Industri, 2019Co-Authors: Dinda Nurlisa RiantiAbstract:Salah satu jenis sampah yang banyak mencemari lingkungan adalah sampah plastik. Dampak negatif yang ditimbulkan oleh sampah plastik selain dapat mengurangi kesuburan tanah yaitu menyumbat saluran drainase, selokan dan juga sungai. Salah satu sungai yang paling tercemar di Indonesia dan di dunia adalah sungai Citarum. Berbagai cara telah dilakukan untuk menanggulangi sampah dan limbah yang terdapat pada sungai Citarum, salah satunya mesin pengangkat sampah yang terdapat di sungai daerah Pasar Kordon, Kecamatan Bandung Kidul, Kota Bandung. Namun dengan adanya mesin tersebut menimbulkan masalah baru di daerah sekitar sungai seperti penyebab banjir, karena sampah yang terhadang membuat aliran air menjadi terhambat dan meluap keluar sungai. Desain mesin Automated River (AURI) Cleaner dirancang untuk mengatasi permasalahan tersebut. Terdapat beberapa komponen yang diletakan pada mesin Automated River Cleaner yaitu Trash hook, kapal, Trash Screen, Trash deliver dan Trash container. Studi ini berfokus pada perancangan desain dari Trash deliver yang terdiri dari 2 buah conveyor. Perancangan desain dilakukan dengan metode perancangan produk rasional dan dibuat beberapa konsep desain. Metode ini terdapat beberapa tahapan yaitu clarifying objectives, establish function, setting requirement, determining characteristics, generating alternatives, dan evaluating alternatives. Setelah tahap penilaian, konsep desain A didapatkan sebagai konsep desain terpilih. Konsep tersebut memiliki belt dengan tipe cleated rubber belt, frame berbentuk frame dengan tiang, drive pulley menggunakan drum pulley, idler roller menggunakan flat roller idler, drive unitnya menggunakan gear motor, pemisah sampah berupa rongga, penahan Trash deliver yang berbentuk engsel/batang, dan controller dengan tipe stepless speed control
