<![CDATA[Pada sebagian Sekolah Menengah Kejuruan (SMK) yang memiliki jurusan teknik elektro dan sejenisnya, Programmable Logic Controller (PLC) telah banyak dipelajari untuk menghasilkan lulusan yang memiliki kemampuan yang dibutuhkan oleh industri saat ini. Dalam kondisi pandemi Covid-19, pembelajaran PLC pada sebagian sekolah menjadi terhambat karena tidak semua siswa memiliki kuota internet maupun kapasitas komputer yang cukup besar untuk mengunduh ataupun menginstall perangkat lunak untuk mempelajari PLC. Permasalahan ini dapat diatasi dengan melakukan pembelajaran Ladder Diagram PLC dalam jejaring tanpa perlu mengunduh perangkat lunak, yaitu melalui situs PLC Fiddle. Karena PLC Fiddle belum banyak diketahui dan dipelajari oleh para pengajar ataupun pembelajar di Indonesia, pada kegiatan ini modul dasar tutorial PLC Fiddle dibuat.untuk memudahkan para guru SMK memberikan pembelajaran kepada para siswa dalam jejaring. Selain itu, bagi SMK yang belum menerapkan pembelajaran PLC karena keterbatasan fasilitas, pengenalan dan pembelajaran PLC Fiddle dapat digunakan untuk memulai memberikan pembelajaran PLC kepada para siswa. Selanjutnya, modul tutorial ini akan mulai diperkenalkan melalui kegiatan pelatihan untuk para guru SMK.]]>

<![CDATA[Natuna Sea is one of the places in Indonesia, which has a high potency of fish up to one million ton per year. Fisherman in Indonesia relies too much on the fossil fuel, which has limited resources. The author wants to redesign the fishing vessel into the battery electric fishing vessel that can be recharge to reduce the use of fossil fuel and also to increasing the revenue of the fisherman. To minimize the capacity of the battery, the fishing activities concept is also change into centralized fishing activities which the activities is centralized in an open sea and has the offshore building as the fishing base that has power station to recharge the batteries and cold storage to collect all the fishes. As the object to redesign, it is used 10 GT purse seine fishing vessel. As the results of the calculation, it gets the total battery capacity 6000 Ah for operation 11 hours (4 hours travel time, 6.5 hours fishing activities, and 0.5 hours break). Based on the technical and economic analysis, it can be concluded that the battery electric fishing vessel has a better revenue and fewer expenses than the diesel-powered fishing vessel.]]>

<![CDATA[Fuel is one of the important component of ship operations. The overall operating cost of the vessel, approximately 60% consists of fuel costs. The unavailability of fuel causes the ship's operational processes to be adversely affect the company from both technical and material terms. It is a bad condition if ship’s fuel does fulfilled the time schedule. To reach the fuel operation criteria and help ships crew operate the fule system, we propose the method to control fuel system. Our objection is how to make ship fuel system can be operated automatically as well as temperature control system on the vessel using PLC. This automation system relies on high level sensors and low level sensors as well as temperature sensors in each tank to trigger the performance of each of the fuel system support equipment such as pumps, valves, heaters. The sensor and thermometer in the tank will be processed by the PLC prior to controlling the equipment. Processing is sequentially adjusted to the processing sequence of HFO fuel. Processing is done based on existing ship data but still using the control manually. As well as recommendations from the classification bureau and machine manufacturers. The work process of the system can be monitored as a whole through Human Machine Interface. The monitor consists of a view that contains all the work of the existing system. The PLC used is OMRON CPM2A with CX-Programmer software and CX-Designer monitor. So by simply using a control device in the form of PLC, HFO processing can be operated automatically both when the ship is idle or in sail condition]]>

<![CDATA[Perkembangan pendidikan tingkat menengah di Indonesia saat ini sedang difokuskan untuk meningkatkan kuantitas maupun kualitas lulusan Sekolah Menengah Kejuruan (SMK) yang mampu memenuhi kebutuhan industri. Salah satu teknologi yang saat ini banyak digunakan di industri darat maupun di bidang maritim adalah teknologi otomatis berbasis Programmable Logic Controller (PLC). PLC merupakan salah satu mode kontrol otomatis yang memerlukan logika desain untuk menjalankan aturan dan langkah-langkah kontrolnya, sehingga diperlukan pengetahuan dan kemampuan untuk mendesain PLC. Namun demikian, dengan situasi pandemi Covid-19 menjadikan pembelajaran PLC menjadi lebih sulit dilakukan. Untuk mempelajari cara memprogram PLC, siswa maupun guru harus memasangkan piranti lunak yang membutuhkan kapasitas besar dan membebani komputer. Solusi dari permasalahan tersebut adalah dengan mempelajari pemrograman PLC melalui media daring, yaitu melalui PLC Fiddle. Media PLC Fiddle sendiri tergolong baru dan belum banyak diketahui oleh pengajar di Indonesia. Dengan dilakukan pelatihan dasar PLC melalui media daring kepada guru-guru SMK di Surabaya, diharapkan guru-guru SMK dapat tetap mengajarkan kemampuan untuk mendesain PLC kepada siswa sesuai kebutuhan industri walaupun dunia masih dilanda pandemic Covid-19. Selanjutnya, diharapkan bahwa para guru tersebut dapat mengaplikasikan ilmu dalam mendesain PLC dalam proses belajar mengajar, sehingga lulusan para lulusan SMK dapat memiliki kemampuan untuk mendesain PLC dengan baik.]]>

<![CDATA[Pandemi covid-19 telah menyerang Indonesia selama lebih dari satu tahun. Pandemi covid-19 ini tidak hanya mengancam keselamatan nyawa masyarakat Indonesia secara langsung, tetapi juga menurunkan tingkat perekonomian di skala industri maupun skala rumah tangga, sehingga berdampak menaikkan angka pengangguran dan menurunkan tingkat kesejahteraan masyarakat. Dengan berkurangnya ketersediaan lapangan pekerjaan termasuk di sektor maritim, lulusan Departemen Teknik Sistem Perkapalan (DTSP) ITS akan menemui tingkat persaingan yang lebih berat untuk dapat memperoleh pekerjaan di industri maritim. Untuk dapat memenangkan persaingan untuk memperoleh pekerjaan tersebut, kemampuan teknis yang tinggi sangat diperlukan. Salah satu kemampuan teknis yang dapat dikembangkan \textit{fresh graduate} DTSP dan menjadi unggulan dibanding pesaingnya adalah kemampuan untuk menganalisis performa dari sistem kelistrikan kapal. Selama ini, kemampuan tersebut telah diajarkan dalam perkuliahan, namun hanya secara manual dengan perhitungan perkiraan, karena keterbatasan waktu sesuai dengan jumlah SKS yang tersedia. Oleh karena itu, pada kegiatan pengabdian masyarakat ini direncakan pemberian pelatihan kepada fresh graduate DTSP untuk menganalisis kelistrikan kapal dengan lebih cepat dan akurat menggunakan bantuan perangkat lunak. Dengan mengikuti pelatihan ini, kemampuan unggulan fresh graduate DTSP akan semakin meningkat dibanding pesaing mereka untuk mendapat pekerjaan di industri maritim, sehingga memudahkan para fresh graduate DTSP untuk lebih cepat dan mudah dalam memperoleh pekerjaan di industri maritim.]]>

<![CDATA[Renewable energy is a type of alternative energy that can be utilized to generate electricity. Wind energy is one of the renewable energy sources. Because of Indonesia's equatorial location, the wind characteristics are moderate, with wind direction and speed changing frequently. To harvest wind energy, it is therefore vital to diversify the types of wind turbines. A screw turbine, also known as an Archimedes screw turbine or a screw turbine, is a type of wind turbine that is often employed in micro hydropower plants. The great efficiency of this turbine is a benefit. This screw turbine will use a Horizontal Axis Wind Turbine (HAWT). The advantage of using the horizontal axis over the vertical axis is that the rotor's efficiency is higher. The screw turbine was changed in this study by adding flaps to boost torque and rpm performance while also increasing wind catchment. The model design with the inclusion of 3 cm flaps with a flap angle of 30° has a high torque and angular velocity with a torque value of 0.00609 Nm and an angular velocity of 12.55 rad/s at an airflow velocity of 3.4 m/s, according to the results obtained from model simulation using CFD (119,84 RPM). Power Coefficient (CP) = 0.00659, Torque Coefficient (CQ) = 0.01990, and Tip Speed Ratio (TSR) = 0.331357.]]>

<![CDATA[Sea level is always changing, either influenced by meteorological aspects, gravitational forces, or geological effects. Monitoring the sea level is very beneficial, especially in such a big archipelago as Indonesia. This monitoring system is designed to use accelerometer sensor to sense the sea level changes vertically to obtain the level changes over time. This device is also featured by internet connection so that the data obtained from the sensor could be process on site using Arduino microcontroller and then sent to online website for remote monitoring process. This research is using experimental method, focusing on the electronic system design. The working flow of the research is started with literature studies and problem statement, then followed by system design, continued to software design, server building, and software and hardware integration. The last step is to test the device and analyze the result. After trial using simple pulley system, it is found that this device is able to sense the vertical level changes well, with an error for the sensor itself is at most 6 cm or about 2%. But there are some connection problems occurred between the device and the internet which resulted in a delay on the process, making the online monitoring system not perform as desired.]]>

<![CDATA[The increase in electricity demand in Selatpanjang, Meranti Island Regency, Riau continues to occur. However, the availability of diesel fuel types is increasingly scarce and the price is increasingly expensive. Therefore, another generator is needed, namely a relatively cheap coal-fired power plant and the availability of coal reserves in the Sumatran region. One of the problems in the economic operation of a generating system is economics dispatch, which is how to obtain minimum operating costs while meeting existing and reliable limits. For this reason, an economic dispatch analysis is needed for the optimal generating system by using the linear programming method. This economic dispatch analysis uses operational cost as a parameter and is done by using software assistance in the form of Matlab. Based on the results of loading with the same variation, the power generation based on economic dispatch calculations has an average load factor smaller than the average load factor based on unit commitment improvement calculations. Thus, the generation with economic dispatch has a higher specific fuel consumption (g/KWH) than the unit commitment improvement so that the fuel consumption price is issued higher.]]>
