Abstract

Digitalisation is currently one of the development and operation of a device, platform and media increasingly used by Millennials and Gen-Z to provide information or sell products. Product digitalisation is not only in marketing but also as a promotional medium to create consumption patterns of application users who are highly dependent on lifestyle changes and perceptions of online shopping applications. In this study using quantitative methods are research based on the philosophy of positivism, used to research on specific populations and samples. This study used 100 samples from Medan Helvetia district using cluster sampling method. The results of this study show that the digital devices have a positive and significant influence on the perception of online shopping, the platform digitalisation does not have a positive and significant influence on the perception of online shopping, the media digitalisation has a positive and insignificant influence on the perception of online shopping among millennials and gen-z in Medan City. Digitalisation in online shopping applications has a huge impact on the perception of online shopping application users because the information obtained becomes faster and there is an increase in customer consumptive patterns

Abstract

Pengaturan kecepatan konveyor merupakan aspek penting dalam sistem penyortiran barang yang berpengaruh langsung terhadap efisiensi dan optimalisasi. Penelitian ini mengkaji berbagai metode pengaturan kecepatan konveyor, termasuk pengaturan statis, bertingkat, dan adaptif, serta dampaknya terhadap throughput, akurasi penyortiran, konsumsi energi, dan keausan mekanis. Hasil analisis menunjukkan bahwa kecepatan konveyor yang optimal dapat meningkatkan throughput hingga batas tertentu, namun dapat menurunkan akurasi penyortiran jika terlampaui. Selain itu, peningkatan kecepatan berbanding lurus dengan konsumsi energi dan keausan komponen. Maka, sangat penting menemukan pengaturan yang tepat antara kecepatan, akurasi, dan efisiensi energi untuk mencapai kinerja sistem yang optimal.

Abstract

Potato cutting machines have become tools used in the modern manufacturing industry in the production of various processed potato products. Technological developments also continue in this field, thereby increasing production efficiency and quality. One important thing is its application because it uses an electro-pneumatic system on a potato cutting machine. This system integrates traditional pneumatic technology with advanced electronic control and produces a powerful combination that optimizes the potato cutting process. In this study, we also present a comprehensive review regarding the use of electro-pneumatic systems in potato cutting machines. The application of this electro-pneumatic system to potato cutting machines provides great potential to increase production efficiency and quality. We can see that the cutting process using a pneumatic cylinder based on a programmable logic controller is more efficient in terms of time than manual cutting. Where it only takes 2 seconds at 8 bar pressure.

Abstract

The increasing human population and life dependent on energy causes the planet to lack energy, especially fossil fuels. Renewable energy is energy that comes from a continuous natural process and never runs out, along with the development of the era, new innovations have emerged, especially in renewable energy sources such as hybrid power plants. To determine the effectiveness and suitability of parameters in a Hybrid Power Plant, it is necessary to be equipped with an effective control system and can be monitored from close up or from a distance, therefore a monitoring system based on the internet of things is needed. The results of the tests carried out were charging energy to the battery, the calculated value of the PLTS voltage was 18 V, the battery voltage was 13.01 V while the current produced was 1.05 A. The PZEM004T sensor was simulated with a load of two soldering irons, it was known that the sensor detected a voltage of 226.6 V, a current of 0.26 V, and a power of 59.00 V, the data was sent to the thingspeak platform in 10 seconds.

Abstract

Seiring dengan kemajuan teknologi di segala bidang, maka sumber listrik utama dari PLN sangatlah penting terhadap penyaluran energi listrik bagi layanan publik, mungkin itu daya besar maupun daya kecil. Akan tetapi suplai listrik utama dari PLN tidak selamanya berkesinambungan atau terus-menerus dalam penyalurannya. Suatu saat pasti terjadi pemadaman listrik yang bisa disebabkan oleh gangguan pada sistem pembangkit, maupun gangguan sistem distribusi. Agar suplai listrik bisa dipastikan tetap terjaga, maka tujuan dari penelitian ini adalah untuk merancang sistem automatic transfer switch yang bisa dikontrol dari jarak jauh menggunakan gadged android sehingga memudahkan pengguna untuk memantau maupun mengontrol keluarnya arus listrik. Manfaat dari pembuatan alat dalam Tugas Akhir ini adalah memberikan kemudahan untuk pengoperasian genset secara otomatis serta memberikan kemudahan agar energi listrik tetap berkelanjutan.

Abstract

The rapid advancement of digital technologies has significantly influenced industrial automation, particularly with the integration of the Internet of Things (IoT) into Supervisory Control and Data Acquisition (SCADA) systems. SCADA systems play a critical role in monitoring and controlling industrial operations, such as manufacturing, energy distribution, and water management. However, managing large-scale operations requires efficient maintenance strategies, and predictive maintenance has emerged as a solution to anticipate equipment failures through real-time data. This research aims to explore the integration of IoT into SCADA systems to optimize predictive maintenance. The study uses a qualitative literature review approach to analyze current practices and challenges in implementing IoT-based predictive maintenance in industrial automation. The findings indicate that IoT integration significantly enhances SCADA systems by enabling real-time monitoring and predictive analytics, leading to reduced operational costs, improved efficiency, and extended equipment lifespan. However, challenges related to data security, interoperability, and infrastructure remain significant. The results of this study provide insights into the effectiveness and potential of IoT in predictive maintenance optimization for SCADA-based industrial systems.

Abstract

Agriculture is a very important part of society in Indonesia. Agriculture is still a source of income for some people because most areas in Indonesia are agricultural land. To develop the results of agricultural land, but many agricultural lands have been converted. There is another way for people to utilise the narrow lands around the neighbourhood with the use of hydroponic planting method. Hydroponics is one of the modern methods of farming without using soil but using water by emphasising the fulfilment of nutrients and pH regulation in plants. This research aims to know and understand the characteristics of each tool that will be used. Measuring pH by using an automation system on hydroponic plants. Therefore, it is necessary to make innovations to the measurement of pH in hydroponic plants using an automation system. Controlling pH can be done manually using a pushbutton and automatically by determining the setpoint compared to the sensor reading. In a manual way we can adjust the pH level as desired by pressing the pushbutton either to increase the pH value or decrease the pH value. But in the automatic running system we only need to determine the setpoint used, in this system <7 then the pH up pump will turn on>7 then the pH down pump will turn on if =7 then both pumps will be in a state of not turning on. The components that can support this system are of course the sensor as a reader of the pH value, and the microcontroller as processing the pH data on the sensor then giving commands to the actuator, and of course the actuator is a pump. Automation of pH in hydroponics is certainly very effective and efficient compared to the manual method where we must always monitor directly, check directly, and control the pH value directly. But in the pH system automation everything can be done only through a smartphone.
