Abstract

This paper presents a design concept of Ocean Thermal Energy Conversion (OTEC) plant built in Mamuju, West Sulawesi, with 33 MWe and 7.1% of the power capacity and efficiency, respectively. The generated electrical power and the efficiency of OTEC plant are enhanced by a simulation of a number of derived formulas. Enhancement of efficiency is performed by increasing the temperature of the warm seawater toward the evaporator from 26ËšC up to 33.5ËšC using a flat-plate solar collector. The simulation results show that by increasing these a water temperature up to 33.5ËšC, the generated power will increase up to 144.155 MWe with the OTEC efficiency up to 9.54%, respectively. The required area of flat-plate solar collector to achieve the results is around 6.023 x 106 m2.

Abstract

Coupling is one of the components are widely used in various industries. Coupling is widely used as a power transfer transmission. Coupling have a long life time, it mean coupling was damage if out of the maintenance. The one factor is misalignment. This study aim to determine the effect of misalignment on the coupling transmission to vibration, electric current and shaft rotation speed. In this study, was done alignment process with variations of misalignment on the coupling transmission and was done measurement value of vibration,  electric current and shaft rotation speed. The study results show that the changed of misalignment would give a positive impact to vibration and electric current. For the effect misalignment to shaft rotation speed, the study results show that the changed of misalignment would give a negative impact to shaft rotation speed.

Abstract

Setiap beberapa waktu perawat melakukan pemantauan tetes cairan infus dengan manual secara langsung. Bahkan, saat cairan infus akan habis, keluarga pasien harus memanggil perawat untuk melakukan penggantian cairan infus. Hal ini bisa menyebabkan terlambatnya penanganan terhadap pasien karena keterbatasan waktu. Oleh sebab itu, dibutuhkan sebuah alat pemantauan tetes cairan infus yang dapat memberikan notifikasi otomatis bahwa cairan infus akan habis. Artikel ini menjelaskan tentang implementasi alat pemantauan tetes cairan infus berbasis IoT yang terhubung dengan perangkat android. Prototipe ini menggunakan sensor Optocoupler sebagai pendeteksi adanya tetes cairan infus, Motor Servo SG90 untuk menekuk selang infus, Mikrokontroler ESP32 sebagai pengendali. Komunikasi perangkat keras dengan perangkat android menggunakan server lokal sehingga harus menggunakan Hotspot WiFi yang sama. Data yang dikirimkan dari perangkat android akan tersimpan ke database kemudian diakses oleh ESP32 sehingga menjalankan sensor dan motor servo. Pada android application terdapat informasi kondisi tetes cairan infus yang sudah dikonversi menjadi persentase sisa cairan infus. Hasil eksperimen menunjukkan bahwa prototipe dapat melakukan pengaturan tetes cairan infus per menit sesuai dengan yang diinginkan dan android application dapat menampilkan status dan mengirimkan notifikasi secara akurat. Sebagai kesimpulan dari hasil pengukuran, rata – rata rasio persentase yang dicapai dalam pengujian mencapai 70 % dengan rata – rata error sebesar 1,46 %.

Abstract

Gear is a rotating machine that is widely used as a power transfer transmission in many industries. Gear has a long life times. However, the gears can be damaged due to many factors such as out of the maintenance, which one factor of misalignment. This study aim is to determine the effect of misalignment on the gear transmission to vibration, electric current and shaft rotation speed. In this study, was done alignment process with variations of misalignment on the gear transmission alignment kit and was done measurement value of vibration, electric current and shaft rotation speed. The study results show the greater the misalignment, the greater the vibration that occurs either radially or axially for all conditions measured. The shaft rotation was slower with the greater misalignment. The misalignment can affect the decrease in the rotation speed of the shaft. Therefore, it can reduce the efficiency for power transmission of engine.

Abstract

This paper presents the development of a hot air dryer conveyor for the automotive industry in the tampo printing part process. The research started by designing and creating the actual device that is ready to use and be implemented in the industry. The method provides the detail of the drying chamber, hot air dryer, and its mathematical model. The chosen hot air dryer is Suiden SHD-9F II and is operated on the factory default setting of auto-tuning mode. The performance evaluation studies the indicator performance of hot air dryer for the chosen size of drying chamber, the robustness of the system against fluctuating environmental air change rate, the ducting capacity, and the damper opening value estimation performance. The result of this system is working well at specification requirement of air change rate from 15 to 21 at 80% of its maximum capacity for error compensation and its already being successfully implemented.
