Abstract

This work aims to improve pedestrian functions, improve the welfare of waste banks and scavengers, and fulfil electricity needs for the surrounding community towards Society 5.0. The method of writing is done with secondary data through the latest literature study. The literature study focused on the development of technology for processing plastic waste, photovoltaic (PV), and piezoelectric (PZT) and their use in road construction. The results of the discussion show the potential of plastic waste as a composite material for paving. Similarly, PV and PZT can be integrated together as a producer of renewable electrical energy. With this innovation, VIZO is expected to be able to reduce plastic waste and provide welfare for the community, scavengers, waste banks, and help local government energy-saving programs.

Abstract

Image restoration technology has many functions and roles in various fields. With the image restoration technology, it is easy for human to describe something through the displayed pictures. However, in practice there are many shortcomings, one of which is the amount of noise and the resulting image is not clear. Therefore, the image restoration method is a solution that can be used to solve this problem. With image restoration, the image that have been previously produced can be modified so that the results are clearer. Maxwell Boltzmann distribution plays a very important role in supporting this image restoration method. The applications in Maxwell Boltzmann we will discuss in here are image restoration filters with Simulated Annealing in magnitude image restoration, modelling in adaptive spatial image restoration, and endoscopic image restoration. In conclusion, image technology can be found in various fields and with different technologies.

Abstract

Pada era Revolusi Industri 4.0 berkembang internet of things dengan sangat cepat yang menandakan dunia industri telah mengalami kemajuan. Kemajuan ini adalah penggabungan teknologi otomatisasi dan teknology cyber. Kemajuan teknologi telah menghasilkan penemuan-penemuan penting, seperti otomatisasi, analisis data, simulasi, integrasi sistem, penggunaan robot, dan teknologi cloud untuk penyimpanan data. Hal ini menyebabkan terhubungnya semua sektor industri melalui website yang terintegrasi secara otomatis. Kemajuan teknologi telah mengubah kehidupan manusia, termasuk gaya hidup berkelanjutan. Sehingga masyarakat perlu menyesuaikan perubahan sejalan dengan transformasi digital. Digitalisasi memunculkan penciptaan robot-robot yang dapat membantu pihak industri. Namun adanya digitalisasi juga menimbulkan polemik di masyarakat, yaitu anggapan Revolusi Industri 4.0 yang menghadirkan robot sebagai pengganti peran manusia. Polemik ini berdasar dari ketidaktahuan masyarakat mengenai sistem otomatisasi dari robot. Maka menjadi peluang sekaligus tantangan bagi pengabdi untuk memberikan pengetahuan mengenai dasar-dasar sistem otomatisasi kepada peserta didik tingkat sekolah menengah atas.

Abstract

Polystyrene (PS) is commonly employed in insulation, packaging, filters, and medical equipment, with recent studies exploring its potential in fiber membrane production. The electrospinning technique is discussed to synthesize PS fiber membranes with high porosity and controllable diameter. Additionally, incorporating silver nitrate into PS composite fibers is explored for enhanced functionalities such as catalytic activity, high electrical conductivity, and antibacterial activity. However, PS composite fiber membranes with silver nitrate (AgNO3) metal variations are rarely observed. This research aims to modify the microstructure of PS fiber membranes produced using electrospinning by adding silver nitrate (AgNO3) with varying concentrations. PS-Ag fiber membranes are produced using N,N-dimethylformamide (DMF) solvent, which serves as a solvent and a reducing agent for Ag. The results show that the effect of Ag affected the diameter of the PS-Ag fiber membrane, with an average diameter of around 3.67 - 6.93 micrometers. Degradation occurred in these samples at a strong broadening peak near ~1300 cm-1 until ~1600 cm-1 from the Raman results. The FTIR results show that the wavelength of ~3500 cm-1 indicated the presence of OH. The presence of OH indicates that the PS-Ag fiber membrane has the potential for water filtration application

Abstract

The wireless charger is a technology that can transfer energy through an air gap without using cables. This technology is essential in welcoming other technological developments in industry 5.0 because of its effectiveness. However, the understanding and development related to wireless chargers are still very minimal, especially in Indonesia. Articles that review wireless chargers are also still very limited in number. Therefore, this article presents a review related to wireless chargers, the development of wireless chargers as electromagnetic applications, and describes the advantages and disadvantages of wireless chargers using the literature study method. The wireless charger is one of the topics discussed in electromagnetics material. Therefore, the information in this article can be used as a reference for educators in teaching students about electromagnetics material.

Abstract

Electrospinning is a method of making nanomaterials that has a fairly easy and flexible process that can produce nanofiber continuously. Nanofiber morphology from the electrospinning process is influenced by several parameters, one of them is temperature as an environmental parameter. If there is no temperature control system in the electrospinning system, it will be difficult to maintain the consistency of the morphology nanofiber and at certain temperatures, nanofibers are not formed. Therefore, this study aims to develop a temperature control system for electrospinning called the Electrospinning Temperature Control (ETC) System and connect it with an internet-of- things (IoT) platform to understand the dynamics of the temperature control process, upload temperature data to the cloud, and remote monitoring. The method used by designing and building system hardware and software, calibrating DHT21 as a temperature sensor and testing system performance. The results show that the calibration of the DHT21 sensor has an accuracy rate of 94.95% and a precision rate of 98.93%, while the results of the performance test show that the system can raise, maintain, and lower the temperature. Further performance testing reveals that the ETC system can operate within a temperature range of 2040C. The IoT system using the Blynk App allows users to remote and monitor easily, and using Google Sheets as a cloud database. The ETC system was successfully built and can be applied to electrospinning experiments.

Abstract

In recent years, electrospinning has become the most common and most widely used nanofiber manufacturing method. One parameter affecting the manufacturing process is the humidity parameter, which affects the morphology. The control tools that have been developed have not been equipped with a remote control and monitoring system. This research aims to develop a humidity control system that can be controlled and monitored remotely and is equipped with data recapitulation. This research used methods from literature studies on humidity control systems, manufacture and assembly of hardware and software, calibration, and performance tests. A humidity control device is produced using a NodeMCU microcontroller connected to the IoT-based Blynk application. This can be controlled and monitored manually with an LCD and Keypad or by using a handphone through the Blynk application, and the humidity value can be recapitulated with Google Sheets in real-time. The sensor used for reading this humidity value is a DHT 22 sensor which has an accuracy value of 99.72% and a precision of 98.81% for 45%-95% humidity. This IoT-based humidity control system device can automate the process of controlling, monitoring, and recapitulating humidity data in real-time.

Abstract

The rotational speed of the drum collector is an important parameter to determine the morphology of the nanofiber. Currently, many researchers are modifying single nozzle into multi-nozzle to obtain a wide range of materials. However, it requires more powerful syringe-pumps or increasing their number, leading to escalated cost. In addressing this issue, the sliding drum collector with an RPM counter is proposed as a solution. This apparatus uses a DC motor 775 and a stepper motor Nema17 as the driving device and an IR-sensor as the RPM counter. The RPM counter on this apparatus has also been calibrated and obtained an accuracy value of 97.87% and a precision value of 96.45%. The performance of the sliding drum collector has been validated. The sliding drum collectors have been proven to produce wider material with an area of (389 ± 8) cm2, (66 ± 18) cm2 larger than an ordinary drum collector.
