Abstract

Kebutuhan manusia semakin lama semakin meningkat, berkembang dan bervariasi,untuk memenuhi alat transportasi. Jumlah penduduk yang semakin meningkatmenyebabkan kenaikan jumlah mobil pribadi. Penggunaan ruang parkir yang luassangat dibutuhkan tetapi tidak efektif. Sistem parkir bertingkat otomatis merupakanalat bantu yang sangat diperlukan dalam pengaturan dan penyusunan parkir mobil.PLC (Programmable Logic Controller) adalah suatu alat berbasis mikroprosesoryang dapat diprogram untuk mengontrol dan mengendalikan proses permesinansecara otomatis. Tujuan penelitian ini adalah merancang dan membuat prototipesistem parkir bertingkat otomatis dengan menggunakan kendali berbasisProgrammable Logic Controller (PLC) dan SCADA-Human Machine Interface (HMI).Bahasa pemrograman yang digunakan adalah diagram tangga dibuat menggunakanperangkat lunak CX-Program 9.0. Pembuatan prototipe tempat parkir bertingkatjumlah 16 ruang berbentuk kolom matrik 4 x 4, mekanisme lift pengangkat denganchain transmision, mekanisme roda penggerak dengan roda gigi lurus (spurs gears)dan mekanisme pemindah alat dengan pneumatik secara slider. Pembuatan programuntuk mengendalikan mobil masuk dan keluar tempat parkir yang sudah dibuatdengan menggunakan PLC tipe CPM1A 30 CDR berbentuk diagram tangga.Pembuatan sistem Human Machine Interface (HMI) menggunakan program SCADAsebagai interface atau tampilan penghubung antara manusia dengan mesin untukmenjalankan dan mengontrol alat yang sudah dibuat dan mengambil data analisa.

Abstract

Abstract Wind turbines are the main media that can be used to convert wind energy into electrical energy. The design of a good wind turbine determines the performance of a Wind Power Plant. The Savonius turbine on the vertical axis is an alternative for generating electrical energy because the development of the Savonius Turbine is directed at making economical ones, such as being able to operate at low wind speeds. This study aims to determine the performance of the Savonius turbine that has been made, the resulting generator power, and the efficiency of the generator used. The research was carried out using experimental methods by varying the number of blades 2,3 and 4. Testing was carried out directly in the coastal areas. The results were obtained from data processing are the largest turbine output power on the 2 blade turbine = 38.88 watts. The largest coefficient of power, the 2 blade turbine = 0.235. While the largest output power generated by the generator = 34.3 watts at the 4-blade turbine. The biggest generator efficiency is 12.02% on the 4 blade turbine.

Abstract

This waste problem can be used as new and renewable energy in the form of Refuse Derived Fuel (RDF) fuel. Due to its relation to energy, the calorific value of garbage becomes an important parameter. Water content is one of the important parameters that determine the calorific value. If the moisture content of the waste is high, then the energy needed for drying and destruction through combustion is also high, so a process of reducing the water content in the waste is needed. The drying mechanism is the most important part of the drying technique because by knowing the drying mechanism, it can be estimated the amount of energy and the need for the optimum air mass for drying. This study is to evaluate the needs of air masses, the amount of drying energy needed, then a comparison of drying calculations using the Relative Humidity dryer method through air media is heated by drying using the evaporation method through boiling by heating the walls of the drying room. The energy required in the Relative Humidity dryer method through a heated air medium is not only to heat the moisture content until it can evaporate but energy is also needed to heat the air from the initial temperature of heating the dryer air to the temperature out of the dryer. In addition, the amount of air needed to carry water vapor is very large. Based on the results of the discussion and calculations of each drying method to reduce the mass of water content in wet waste that has been carried out, it can be concluded that the drying method by evaporating the moisture content by heating the drying chamber is more efficient because it requires less energy than the method of blowing heated air.

This research discusses improving solar panels' performance using a single-axis tracking system. This research modelled a singleaxis of solar cell tracking system using a PID controller in Matlab Simulink software. In the tracking system method, the solar cell is simulated on a single axis oriented to elevation angle as input and optimization of precise position control to direct the sun's movement at 07.00 – 17.00 WIB. The simulation results shown that using a PID control in designing a single-axis of solar cell tracking system shows significant results, where the controller design can accurately detect the direction of the sun's movement. Furthermore, the lowest elevation angle is 1.7 degrees, and the highest is 68.21 degrees. Furthermore, solar tracking systems have the potential to absorb more radiation for a greater output of solar cells.Keywords: solar cells, single axis, tracking system, PID controller, Simulink Matlab
