Abstract

Atma Jaya Catholic University of Indonesia has Faculty of Engineering, which is committed to empower its surrounding communities. This empowerment is implemented based on its core values. The present community empowerment activities have been planned through a series of agreements and the main goal of the activities is to develop the entrepreneurship based on the strength of the area. This paper discusses the assistance given by Faculty of Engineering in designing piping installation for supporting aquaponic activities in Desa Sampora. The project was divided into three steps. First, this project focused on observation and data collecting. This first step also involved discussion with experts. Second, it focused on the design process. The result of the first step was used in the design. Third, the design was implemented and installed in the location. All the steps required careful planning to minimize errors. The expected target of these activities was an aquaponic piping design that is feasible to implement to support sustainable and productive entrepreneurship. The final result was piping installation that can grow 120 plants, is easy to clean up, and has area efficiency.

Abstract

In today’s industry, company’s activities are scattered in several locations and need internet for communication purposes. However, it will be dangerous if third-parties have access to their information. One of the solutions for securing information exchange is by using Virtual Private Network (VPN). The VPN protocols that will be used are Point-to-Point Tunneling Protocol (PPTP) with the help of Internet Protocol Security (IPSec). These protocols are simulated in VirtualBox that has been previously installed with two Mikrotik routers and two Windows 7 operating systems. The PPTP and IPSec protocols are configured in both routers through Winbox software. For the computers, the IP addresses are configured along with iPerf software for bandwidth analysis. In this VPN simulation, both computers can communicate with each other and have no problem in accessing the internet. In PPTP’s network, the average bandwidth is 1.293 Mbits/sec. Meanwhile, in PPTP with IPSec’s network, the average bandwidth is 0.853 Mbits/sec. There is a slight difference considering that in PPTP, the data packets are only encapsulated. On the other hand, the data packets in IPSec protocol are both encapsulated and encrypted.

Abstract

The purpose of research on this flood prevention system prototype design is to prevent flood caused by overflowing reservoir water. This system prototype uses the Modicon M340 Programmable Logic Controller as a controller and is equipped with a Human Machine Interface feature as a medium for managing and monitoring system performance virtually. This system is supported by a Water-Level Sensor to measure the water level in the reservoir and also the rate of addition of water in the reservoir. The sluice mechanism is driven by a Stepper Motor assisted by the ULN2003 Driver Module based on Proportional, Integral and Derivative (PID) control to maintain the water level in the reservoir. PID control in this system successfully runs optimally at constant KP = 3.5, KI = 2, and KD = 1, with an error result of 0,048%. This constant has the best response time compared to other constants, where rise time = 11.76 s, settling time = 13.95 s, and steady state time = 14.07 s.

Abstract

This research aims to compare the actual production with the simulations using the PVSyst software for the Off-Grid Solar Power Plant (PLTS) in Karuni Village, Southwest Sumba. The Off-Grid PLTS in Karuni Village is a vital solution for improving remote areas' electricity access. Actual energy production data from the PLTS were obtained from monitoring systems, while simulation results were obtained through PVSyst. The analysis results indicate a difference of approximately 10% between the actual and simulated results. It observed that it is influenced by variability in local weather conditions, maintenance, system management levels, and limitations of the simulation model. The implications of this research emphasize the importance of using accurate data in simulations, improving PLTS system maintenance, and developing more sophisticated simulation models. Recommendations for further research include further analysis of factors influencing the differences in results. This study provides valuable insights into the planning and management of Off-Grid PLTS. It offers perspectives on enhancing the accuracy of future PLTS system planning and management.

Abstract

Di Indonesia, PLN adalah penyedia utama listrik rumah tangga, individu, dan industri. Namun, karena pasokan listrik PLN tidak selalu stabil, pembangkit cadangan diperlukan. Karena mereka adalah sumber energi terbarukan dan ramah lingkungan, pembangkit listrik tenaga surya (PLTS) menggunakan energi matahari sebagai sumbernya. Namun, pasokan PLTS tergantung pada cuaca. Untuk mengatasi masalah ini, PLTS dapat dirancang sebagai Pembangkit Listrik Hibrid (PLTH), yang menggabungkan sumber PLN dan pengaturan beban. Studi ini mengembangkan sistem kontrol pintar otomatis dan manual yang menggunakan Automatic Transfer Switch (ATS). Sistem ini menggunakan ESP 32 dan memiliki mikroprosessor dengan modul WiFi 802.11b/g/n ESP 32 di Rentang Frekuensi 2.4 GHz. Studi rumah tangga menunjukkan bahwa kontrol pintar berfungsi dengan baik dalam simulasi dan pengujian. Meskipun ada waktu start-up inverter, delay rata-rata PLN-SHS adalah 1835 ms dan SHS-PLN adalah 2695 ms dalam mode otomatis dan 937,5 ms dalam mode manual dengan kontrol Thinger io. Dalam 12 pengujian, delay rata-rata kurang dari 2 s. Hasil menunjukkan bahwa jarak tidak memengaruhi delay, namun, kecepatan internet ESP 32 dan pengguna memengaruhi delay.
