Abstract

Abstract:This research analyzes the technical and economic performance improvements of the 20 kV Keboansikep feeder network using ETAP 21.0.1 simulation software. The study addresses the problem of high power losses and voltage drops in the existing system, which reduce network efficiency and electricity supply quality. Data collection involved field measurements of feeder load, conductor specifications, transformer capacity, and network configuration, followed by modeling and simulation in ETAP. Two improvement scenarios were evaluated: Option 1, upgrading conductor cross-sectional area to 240 mm, and Option 2, adding a new feeder line to distribute the load more evenly. Simulation results show that in the existing condition, total power loss reached 246.11 kW with a maximum voltage drop of 3.8%. Option 1 reduced power loss to 153.08 kW and voltage drop to 2.5%, while Option 2 achieved the best performance with power loss of only 65.99 kW and voltage drop of 1.2%. From an economic perspective, Option 1 generated annual energy cost savings of approximately IDR 896 million, while Option 2 saved around IDR 1.73 billion annually. Although Option 2 requires higher investment, it offers greater long-term benefits in terms of energy efficiency, voltage stability, and operational reliability. The findings provide practical insights for electricity distribution companies in selecting cost-effective and technically sound solutions to minimize network losses and enhance service quality.

Abstract

To power low-power household appliances, this study investigates the harvesting of RF signal energy using a Villard–Dickson rectifier circuit and a 470 MHz dipole antenna. The RF signal from the handy talkie is converted into DC voltage when measured from a distance of 5 to 25 cm. The voltage drops from 7.7V to 1.5V, and the current drops from 30mA to 10mA. A relationship showing the voltage and current decreasing almost inversely with distance was found thru logarithmic regression data analysis. A high coefficient of determination indicates compatibility with free-space propagation theory. At a distance of 5 cm, the highest RF-to-DC conversion efficiency reached 18.3%. The resulting regression model allows for performance prediction at distances beyond testing and serves as a practical guide for building wireless power transmission systems and low-power IoT applications. Additionally, this model also serves as a scientific reference for research and dissertations in the field of RF energy harvesting. Highlights: RF-to-DC conversion achieved up to 18.3% efficiency at 5 cm. Voltage and current decrease inversely with distance, supported by logarithmic regression. Regression model enables prediction and application in low-power IoT systems. Keywords: regresi logaritmik, rectifier Villard-Dickson, antenna dipole

Abstract

Keamanan properti menjadi salah satu aspek penting dalam kehidupan sehari-hari, termasuk dalam konteks perlindungan hewan peliharaan seperti burung. Burung, terutama yang bernilai tinggi atau langka, seringkali menjadi target pencurian. Oleh karena itu, diperlukan sistem keamanan yang efektif untuk melindungi burung peliharaan dari ancaman tersebut. Sistem keamanan tradisional umumnya mengandalkan metode seperti kunci fisik dan pengawasan manual, yang seringkali tidak cukup efektif dalam mencegah pencurian atau merespon ancaman secara real-time. Oleh karena itu, integrasi teknologi modern dalam sistem keamanan menjadi sangat penting. Salah satu teknologi yang dapat diandalkan adalah kamera berbasis IoT yang dapat memantau dan mengirimkan informasi secara langsung kepada pemilik melalui aplikasi pesan instan seperti Telegram. Baterai sebagai catu daya untuk semua komponen dalam dalam rangkaian dengan tegangan +5 volt. Untuk memonitoring sangkar burung, sensor PIR akan mendeteksi pergerakan melalui radiasi inframerah yang dipancarkan oleh tubuh manusia ataupun objek yang bergerak dan diwaktu yang bersamaan kamera dari ESP32-CAM melakukan pengambilan gambar lalu dikirim ke mikrokontroller ESP32-CAM, kemudian gambar akan dikirim ke Telegram dan mengirim notifikasi ke smartphone. Dan dapat  disimpulkan jika alat yang peneliti jabarkan berfungsi dengan baik dan sebagaimana dengan fungsi dan tujuan alat tersebut dibuat. Hal itu dibuktikan dengan bot aplikasi telegram yang berhasil terhubung dengan sistem dan menampilkan kondisi sekitar sangkar burung yang dijadikan obyek pada penelitian kali ini. System pada alat tersebut juga dapat  beroprasi dengan baik mesikpun dengan jarak yang jauh.

Abstract

The emergence of the Lapindo Sidoarjo mudflow has a long history since 29 May 2006. The point of the mudflow is in Siring Village, and until now, it has shown no signs of stopping. Sidoarjo residents are still fearful of the impact and recurrence of the mudflow, especially those still living around the embankment. The real impact is often still felt, such as embankment leaks, embankment collapses, or overflowing water mixed with mud during high rainfall, making people who still live around the embankment anxious. The unavailability of monitoring information to the public and the unclear mitigation system makes it necessary to have an information system that is easily accessible to the public. Therefore, by utilizing the advances in Internet of Things technology, this research will design a prototype system to monitor the conditions around Lapindo Sidoarjo Mud using Telegram Bot as a user interface, the ESP32-Cam microcontroller board, SW-420 vibration sensor, and MPU-6050 accelerometer sensor. The result of testing this prototype tool is that the Telegram user will receive a notification if the condition of the prototype field is experiencing vibrations or changes in position. Other than that, the Telegram user can also request real-time information, such as temperature, the axis position of the prototype as an initial benchmark, and the current photo to know the condition of the Lapindo Sidoarjo mud embankment. That way, it is hoped that this prototype system will become a monitoring and mitigation solution for the local people and the general public who reach this Telegram Bot room chat.

Abstract

 Currently, the industrial world cannot be separated from plastic waste, one of which is sheet plastic waste, where this type of waste is very difficult to decompose in the soil, so it is necessary to recycle plastic waste by crushing it and then melting it in processing media such as plastic injection machine. Sheet plastic is usually processed through a shredding or crushing process using a plastic cutting machine. Most of the shredding machines in the industrial world still add plastic waste manually, with the shredding machine components still using a single motor which is used to drive the plastic shredding machine. To solve the above problem by adding several components to the plastic waste shredding machine so that it can be operated automatically using an Omron CP1E PLC, adding a blower motor and a traction motor that uses an inverter or PWM (Pulse Width Modulation) which functions to pull the remaining sheets. The plastic is then shredded by a grinder motor and the shredded results are moved by a blower motor to a special waste bin. This research applies research and development methods with a focus on designing a plastic chopping machine that operates automatically with a continuous system, based on a PLC using CX-One software. This research proves that automatic plastic shredding machines can increase efficiency, work safety and reduce production costs.
