    Ships are basically a means of sea transportation, which connects an island or between regions of a country, which is used as passenger transportation, as well as transportation of goods. As the largest archipelagic country in the world, Indonesia has waters with two vast seas which are larger than the land. Therefore, sea transportation has an important role for the sustainability of the economy in Indonesia, so the need for developers in the maritime sector needs to be increased, one of which is in the field of Shipyards. In the ongoing docking process, it is necessary to schedule the work. So that the project runs in a structured manner, it is necessary to pay attention, because scheduling a project itself helps to detail the activities of an activity, the time required for project completion so that the project is on time Completion and there are no delays in workmanship Critical path method (CPM) itself is a method for identifying completion in a project to complete the completion of a project so that it is on time. And the authors use this method to help resolve and compare between the 2765 dwt tanker scheduling made by the shipyard and using the critical path method (CPM). The results of my research entitled " analysis of activity planning in the 2765 dwt tanker repair process using the critical path method (cpm) " are. The schedule made by the shipyard gets a completion time of 61 days, whereas if you use the critical path method, it takes 48 days

    Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2009.Cataloged from PDF version of thesis.Includes bibliographical references (p. 37).Recent trends of green energy upgrade in commercial buildings show promise for application to residential houses as well, where there are potential energy-saving benefits of retrofitting the residential heating system from single-zone to multi-zone temperature control. The objective of this thesis is to design a physical model to simulate the thermal profile of a residential building with a conventional single-zone central heating system. A scale model of a 2-story house was designed and constructed at 1/20 of the length scale of an average lifesize house, with an external heater and five temperature sensors connected to Vernier LabPro for data acquisition. Comparison between scale model prediction and experimental result shows similarity in steady state values for temperature and characteristic heating/cooling time constants. This thesis is an important first step toward designing a model house for multi-zone heating studies.by Alice Su-Chin Yeh.S.B

    A Force Balance to Measure the Total Drag of Biofilms on Test Plates

    A floating force balance has been designed and integrated into the working section of a to enable the measurement of total drag on test plates, which form part of the tunnel wall. Measurements completed include a calibration of the rig using a smooth acrylic plate, a smooth painted plate, and an artificially roughened plate. The painted plate and rough plate have also been studied with biofilms attached to their surface. The water tunnel and total drag rig have been built specifically to allow the detailed investigation of freshwater biofilm effects have on the flow through hydraulic conduits. Calibration results show that useful information can be obtained by using the force balance, particularly in association with other measurement techniques. Research into the effects of biofilms showsthat large increases in friction and effective roughness can be expected

    Estimasi Kebutuhan Material plat yang digunakan dalam proses reparasi kapal merupakan kebutuhan utama bahan baku penunjang industri perkapalan. Kita mengetahui bahwa jumlah material tidak pernah tepat dalam suatu pembangunan, yang sering terjadi banyaknya kekurangan dan berdampak pada terganggunya sebuah proses produksi. Keadaan tidak tercukupi suatu kebutuhan sehingga proses produksi bias terhambat atau berjalan lancar, pengadaan bahan baku yang terlalu besar dapat menyebabkan tingginya biaya penyimpanan serta investasi dalam persediaan bahan baku. Material merupakan proyek kontruksi yang mencakup 40-60 % biaya yang akan dikeluarkan oleh pihak perusahaan. Dalam penulisan ini dilakukan analisa tentang Estimasi kebutuhan material pada pekerjaan reparasi PT. Adiluhung Saranasegara Indonesia. Sehingga perusahaan dapat menentukan berapa kebutuhan material yang akan diperlukan dalam pekerjaan reparasi kapal. Kata kunci :  Manajemen Material, MRP,  Reparasi kapal, Sistem Manajeme
