Evaluasi Dan Perencanaan U-Turn (Studi Kasus : Jalan Jendral Sudirman, Kota Dumai)
Full text linkGeneral Sudirman road is one of the main roads in Dumai City which has an important role in supporting vehicle mobility. The U-turn facility on Jalan Jenderal Sudirman is a means used by vehicles to cross over to other road networks. However, one of the problems that often occurs is that vehicles making U-turns at intersections do not follow driving rules, which can cause traffic conflicts. This study aims to evaluate the performance of road sections and the performance of the U-turn in front of the PLN office as well as the illegal U-Turn at DIC 3 intersection, by planning a
new U-turn in front of Awal Bross Hospital so that vehicles do not make U-turns at the intersection. The methodology used in this research is PKJI 2023 and Bina Marga 06/BM/2005. From the results of the evaluation of the U-Turn in front of the PLN office, the queue length obtained on Monday with a peak hour of 23m with a delay time of 11.5 seconds. this shows that there are no significant obstacles and the traffic flow is smooth. And the results of the U-Turn planning obtained a turning radius of 12.8, a median opening width of 25.6 meters, and the selection of the type of U-turn median opening is carried out using a type of U-turn in the middle of the road section with a U-turn movement from the inside lane to the second lane of the opposing lane
Perencanaan Miniatur Sistem Bilga Kapal Cargo
Full text linkThe bilge system is an important part of a ship's system that serves to collect, manage and discharge small amounts of water collected in the bilga well. However, developing a bilge system is not easy because it involves various technical, operational and environmental aspects. In addition to understanding how to design ship building construction, as a student majoring in shipping engineering, you should also understand more about piping systems, one of which is the bilge system. However, to capture material on a material, it will be more effective if students use miniatures as a learning medium for students. This pipe system functions as the main part of the ship that connects the flow of fluid from one place to another. This media helps students to facilitate understanding of a topic that is being conveyed, one of which is about this bilga system, makes the teaching and learning process more interesting, and hopes that students will get a picture that will be a provision before going directly to the industrial world. As described, therefore the authors suggest making a miniature bilga system as a teaching aid that will later be used by students to help the teaching and learning process. The results of the pipe calculation are as follows: Main pipe diameter calculation = 104.6 mm / 4.133 inch, Branch Pipe calculation = 65.14 mm / 2.56 inch, Bilga Pump capacity = 64.46 m3/ hr
Pengaruh Kecepatan Potong Dan Sudut Potong Utama Terhadap Kekasaran Permukaan Pada Pembubutan Baja St60 Menggunakan Mata Pahat Bubut Insert
Full text linkThis research aims to analyze the effect of variations in spindle speed, type of coolant, tool holder angle, and feed motion on the surface roughness of St60 carbon steel in the turning process. Experiments were carried out using a lathe at various spindle speeds of 325 rpm, 500 rpm and 813 rpm, as well as air, cutting oil and water cooling. The tool holder angle variations used are 10°, 15°, and 20°, while the variations in feed motion applied are 0.19 mm/put, 0.23 mm/put, and 0.29 mm/put with a cutting depth of 2 mm. The research results show that a higher spindle speed produces a smoother surface. The use of cutting oil as a coolant produces lower surface roughness compared to air and water cooling. The tool holder angle and feeding motion also influence the surface roughness results, where the tool holder angle of 20° and the feeding motion of 0.23 mm/put produce the smoothest surface. The lowest surface roughness value achieved was 1.96 µm at a spindle speed of 500 rpm, air cooling, tool holder angle of 20°, and feed motion of 0.23 mm/put
Tugas Akhir Optimalisasi Perawatan Dan Penggantian Sarana Bantu Navigasi Pelayaran Didistrik Navigasi Tipe A Kelas I Dumai
Full text linkThis study aims to determine and understand the mechanism of factors causing delays in the maintenance of the Navigational Support System (SBNP). A regular SBNP maintenance schedule is required to keep all facilities functioning properly and ensure the safety and comfort of sailing vessels. Maintenance of SBNP includes routine inspections, periodic maintenance and repairs to avoid sudden malfunctions that could disrupt operations and cause losses. In addition, by complying with the established
maintenance schedule, it can minimize the risk of system failure, maintain asset value, and meet applicable safety standards and environmental regulations. This research uses
the Fault Tree Analysis (FTA) and Minimum Cut Set (MCS) methods to identify and determine the factors that cause delays in SBNP maintenance. This research was conducted from June to July 2024. From the results of the study it can be concluded that the maintenance and replacement of navigational aids has been running well, it's just not optimal
Rancang Bangun Prototype Prmbngkit Listrik Tenaga Uap
Full text linkElectrical energy is the main source of energy needed for every electrical equipment or energy stored in electric current. Electrical energy sources can be converted into other energy to support human activities such as driving motorbikes, lighting lights and can also heat things. Electrical energy is the main source of energy needed for every electrical equipment or energy stored in electric current. In simple terms, the working principle of a PLTU is that water is pumped into a boiler/steam boiler, in the boiler the water is converted into steam. Then steam that has been pressurized and at a certain temperature is channeled into a steam turbine, then the steam energy is used to rotate the turbine to obtain mechanical energy. Steam Power Plants (PLTU) are plants that rely on kinetic energy from steam to produce electrical energy. The aim of this research is to determine the power generated by the turbine and the heat energy required by the boiler. In a PLTU, the primary energy that is converted into electrical energy is fuel. The fuel used can be coal (solid), oil (liquid), or gas
Implementasi Oli Bekas Sebagai Bahan Bakar Kompor Masak Alternatif (Perancangan Oil Stove Single Burner)
Full text linkUtilization of used oil as an alternative fuel for cooking stoves is an innovative effort to overcome the problem of used oil waste. Designing and making alternative stoves with economical design forms, and by using used oil as fuel. The working principle of the stove is by pouring or flowing used oil into the furnace and giving it a preheater by burning it using tissue and the combustion chamber is blown with air using a mini blower that enters through a 2 mm nozzle hole. The stove can produce a hot temperature of 404 ℃ at a wind speed of 14.4 m / s. The flow rate at the tap radius also affects the combustion efficiency in the furnace and the hot temperature in the fire
