Abstract

Polivinylidene fluoride (PVDF) is one type of polymer. PVDF is commonly used as a force, heat and strain sensors due to its piezoelectric properties. However, it needs a special process to create the piezoelectric properties of PDVF. One of the special process to create the piezoelectric properties is surface polarization of PVDF. Two electrodes were placed on the surface of PVDF and a high-voltage DC electricity was used for polarization process. In this study, Piezoresponse Force Microscopy (PFM) and Fourier Transformed Infrared (FTIR) was used to determine the results of the surface polarization. The results showed that PVDF with lateral polarization has a more orderly domain direction and a higher β phase compared to unpolarized PVDF. In addition, the quality decreased with increasing the electrode distance in the lateral polarization.

Abstract

PVDF is one of the materials that has piezoelectric properties that are often used  as sensors  or  actuators.  This  piezoelectric property  can be  activated through a stretching process, and then polarized by giving a DC voltage of 4KV. In this study, PVDF material was polarized by the surface polarization method, which were the results tested using d33 meters. The test results show that the value of d33 is 31,32C/N. After being tested using d33 meters, the PVDF material that has been polarized on the surface was tested as a force sensor whose output voltage was measured using an oscilloscope. The result of test carried out by increasing and decreasing load testing and then sensitivity measurements test. The result of increasing and decreasing load test obtained the biggest deviation is 0.35. The results of the calculation of the sensitivity of the PVDF sensor with a surface polarization is 0.0615V / N. Keywords: Surface polarization, Force sensor, PVDF sensor

Abstract

PVDF sensor is a sensor that is often used to measure force, strain, vibration and heat. In this study, PVDF sensors with surface polarization are used to detect cutting forces on the machine. The PVDF sensor that has been polarized on the surface is placed in the chuck part of the engine. Measuring instrumen for testing and calibrating PVDF sensors is oscilloscope with increased loading and reduced axial and tangential directions. After the calibration process, the PVDF sensor was used to measure cutting force on drilling machine, and then the results were compared with the PCB piezotronics force sensor. The PVDF sensor output signal is measured and studied for its voltage using an oscilloscope, where the output signal is compared to the weight given to the PVDF sensor. From the results of these tests indicate that the maximum deviation in axial loading is 0.32V while the tangential loading is 0.31VKeywords.

Abstract

Energi Baru Terbarukan (EBT) sangat penting untuk terus dikembangkan dikala kebutuhan listrik terus meningkat. Oleh karena itu perlu terus dikembangkan berbagai metode yang dapat dilakukan untuk membangkitkan listrik. Salah satu metode yang bisa dilakukan untuk membangkitkan listrik adalah dengan menggunakan material Polyvinylidene fluoride (PVDF) yang memiliki sifat piezoelektrik. Dengan sifat piezoelektrik ini energi mekanik dapat dikonversi menjadi energi listrik. Energi mekanik yang dikonversi menjadi energi lsitrik dalam penelitian ini berasal dari ombak. Arus listrik yang dikeluarkan oleh PVDF disearahkan dengan penyearah arus. Nilai tegangan dan arus diukur dengan sensor arus dan tegangan yang diterjemahkan dengan Arduino. Hasil pengukuran tegangan dan arus disimpan dalam micro SD. Adapun hasil dari penelitian ini adalah PVDF dapat mengkonversi energi mekanik ombak ke energi listrik. Hal ini terlihat dari besar tegangan dan arus yang dihasilkan akan naik jika terjadi hempasan ombak. Daya rata-rata yang dihasilkan mencapai 2,29 mW.

Abstract

This study aims to design and test an automatic fish feeder (AFF) controlled by a microcontroller with an electricity supply from a solar cell. To build a reliable and accurate system, input data is collected for design, followed by system development, feasibility analysis, and performance testing. The test results show that AFF works according to the settings of the microcontroller, where the servo motor can open and close the feed channel periodically, three times a day. The feeding schedule is set at 07.00, 12.00, and 16.00. In addition, fundamental indicators including feed conversion ratio (FCR) and feed efficiency (FE) are showing positive results. Through the application of AFF which replaces manual feeding, the FCR is obtained at 1.15 from the initial value of 1.44. Meanwhile, FE increased from 69.4% to 86.8%. Technically, AFF is suitable for use by tilapia and carp farmers.

Abstract

Human commonly use plastic because it is easy to get, economical, heat-resistant, and lightweight. PET plastic is widely used for single-use bottles. This high usage of plastic leads to the accumulation of plastic waste which is difficult to decompose and damaging the environment. The solution is to recycle plastic using an HSS crusher-type plastic shredder. The design process of the HSS crusher-type plastic crusher machine includes: the data collection process, the design starting from the design concept, design embodiment, and design details using Solidworks 2021 Software in two- and three-dimensional forms then processed for design validation. Then, the supervision of the tool manufacturing was continued to determine the suitability of the tool with the created design, machine testing, and evaluation. The dimension of this HSS crusher-type plastic shredding machine design is 775 í— 635 í— 1553 mm with a machine weight of 200 kg. The machine components consist of AS blade, US blade, side blade lock, side blade, UCP 208, size sieve, US knife holder, machine frame, output, holder, US cover, top cover, pulley cover, pulley, output cover, input, hopper, and machine wheel.
