<![CDATA[This paper proposes method of series DC arc fault protection using low cost microcontroller. Series DC arc fault occurs when gap between conductor or wire flows a current. Series DC arc fault can cause fire hazard if do not detected and protected. However, Series DC arc fault is difficult to detected using conventional protection. To detect series DC arc fault accurately using fast Fourier transform (FFT). FFT is used to transform signal in time domain to frequency domain. Series DC arc fault has different characteristic compared by normal current in frequency domain. Therefore, the proposed algorithm for protection of series DC arc fault based on magnitudes of the current in frequency domain. Hardware system is implemented by 100 V DC power supply and DC arc fault generator. Test result is conducted experimentally under varying of load current such as 2 A, 2.5 A, 3 A, 3.5 A, 4 A and 5 A. Experimental testing results show that Series DC arc fault protection has time for trip of 0.48 s, 0.26 s, 1.04 s, 0.68 s, 0.44 s and 0.48, respectively. The fastest time for trip is 0.26 s with current of 2.5 A. Therefore, the proposed algorithm for series DC arc fault protection can operate to trip accurately and have the good performance.]]>

<![CDATA[Udang rebon merupakan hasil tangkapan utama nelayan sukolilo baru, Kenjeran, Surabaya. Saat musim panen, nelayan mampu mendapat udang rebon hingga 150kg/kapal dengan jumlah kapal yang aktif melaut ±30 unit.. Untuk menghasilkan udang rebon yang bagus, perlu proses pengeringan dengan memanfaatkan panas matahari selama 2-3 hari tergantung cuaca. Padahal puncak musim udang rebon terjadi pada saat musim penghujan. Hal ini menjadi kendala, karena nelayan masih sangat ketergantungan dengan panas matahari untuk proses pengeringan. Untuk mengatasi permasalahan tersebut, maka perlu adanya alat pengering modern. Terdapat dua bagian utama yakni bagian sistem pemanas otomatis dan sistem pengering. Sistem pemanas otomatis menggunakan pemanas infrared berbahan bakar gas LPG dengan pengatur suhu. Bagian kedua yakni sistem pengering menggunakan rak bertingkat, agar dapat menghemat lahan penjemuran. Alat pengering udang rebon menggunakan sumber bahan bakar gas LPG, dengan tujuan untuk menghemat ongkos produksi dibandingkan jika memakai sumber energi listrik. Alat ini mampu mengeringkan udang rebon hingga 50 kg dalam waktu 2.5 jam dengan suhu pemanasan 45-50 derajat celcius.]]>

<![CDATA[Renewable energy is increasingly popular and in demand throughout the world as an alternative to increasingly limited fossil energy, one of which is wind turbines. Wind turbine research on ships has great potential in developing renewable energy at sea. The aim of this research is to increase the efficiency of converting wind energy into electrical energy by designing a low cost wind turbine and analyzing the design efficiency of the wind turbine blade angle, namely 90˚, 95˚, 100˚. This research uses an experimental method with observation techniques, as well as measurement and recording as data collection techniques. This research was conducted on the Bung Tomo training ship for 3 days. The research results show that making a wind turbine using PVC as a base material costs Rp. 243,000.00 and produces the largest average voltage of 73.8 Wh. The influence of variations in the angle of the wind turbine blade can be seen that at an angle of 100˚ it has the largest average power output, namely 1.23 watts per minute and the battery charging time is based on an average current of 0.28 A, namely 12.5 hours when fully charged, whereas at The 90˚ angle produces the smallest average power of 0.76 watts per minute and the battery charging time is 16.6 hours when fully charged. So the 100˚ angle is more effective in charging the battery than the 95˚ and 90˚ angles. The greater the blade angle, the greater the rotation and produce greater voltage, this is influenced by the area of the turbine exposed to wind.]]>

<![CDATA[Technological developments and modern industrial needs increasingly demand high energy efficiency in refrigeration machine operations. In this context, the development of a more efficient cooling machine control system is very necessary. Portable cooler boxes using Thermoelectric Cooler (TEC) technology are an innovation to improve the quality and durability of fish caught by fishermen in Surabaya. This research aims to design and test a cooler box that can maintain low temperatures for a long time. This research method uses experimental methods, a series of tools and uses two test plans, namely: static and dynamic testing. The components used are three Peltier elements supported by a 12V 54A power supply, a 10K NTC temperature sensor, and a passive thermal regulator heatsink with fan. Precision testing data on the comparison sensor (thermodigital), obtained an average value of 3.75%. The error value is still categorized as a safe difference value and the tool works according to its function. Test data shows that the Cooler box can maintain a temperature between 5°C to 10°C, this temperature is ideal for slowing down the process of fish spoilage. Testing was carried out by integrating an Arduino Nano for real-time temperature monitoring which is displayed on the LCD and stored on a MicroSD. Test results show that this cooling system is effective in maintaining a stable temperature under various conditions of use, with an electrical energy consumption of 3111.38Wh per 6 hours.]]>

<![CDATA[Oil is one of the essential lubricating materials for machinery, especially on ships. With the abundant use of oil, waste oil is generated from the remaining oil discharge, causing dirty oil to become waste oil. To monitor the disposal of waste oil by ships, "Waste Oil Monitoring System Using LoRa-Based Arduino Uno" has been created. This tool is also equipped with sensors that can distinguish seawater and waste oil and uses the LoRa system. This method involves researching problems that exist in the shipping environment. The presence of waste oil pollution was successfully detected in the results of this study, and can be monitored remotely through an LCD display with LoRa. In this case study, the device made can detect waste oil and can distinguish it from sea water. The purpose of making this tool is to detect the presence of oil in sea waters in order to reduce and prevent waste oil pollution that can spread widely in sea waters. The system can function properly because there is an error of 2.18% in the fresh water test, 2.08% in the seawater test, 4.55% in the oil test, and 3.08% in the seawater and oil mixture test compared between the pH sensor and the pH meter. The system can work well using LoRa Ra-02, and the transmitted data can be reached stably at a distance of 205m, but if it exceeds that distance, the data can no longer be received by the receiver or becomes invalid.]]>

<![CDATA[Motor induksi (atau motor asinkron), yang merupakan motor Arus Bolak-balik (AC) yang paling banyak digunakan di industri, selalu bergantung pada perbedaan kecil dalam kecepatan antara medan magnet stator yang berputar dan kecepatan poros rotor yang disebut untuk menginduksi arus rotor pada belitan rotor. Dengan demikian, motor induksi tidak dapat menghasilkan torsi pada kecepatan sinkron, di mana slip tidak lagi ada. Sebuah motor bila diizinkan, akan memberikan torsi hingga batas maksimumnya untuk memutar bebannya; terutama di bawah rotor yang terkunci atau berat beban peralatan yang dimuat. Nilai batas torsi maksimum berbeda untuk setiap motor induksi AC dan berbanding lurus tergantung pada karakteristik motor. Dalam beberapa kasus, seperti konveyor, mesin bubut bermotor, atau penggerak motor langsung, jika motor dibiarkan menjalankan torsi maksimum, itu dapat menyebabkan kerusakan permanen pada peralatan. Penelitian ini menyajikan desain sistem Variable Speed Drive (VSD) yang memiliki kemungkinan untuk mengukur kecepatan rotor dan mengendalikan torsi motor asinkron berada dalam batas torsi yang ditentukan.]]>
