Abstract

This paper presents the development of an ultrasonic rat repellent device that integrates a Passive Infrared (PIR) sensor with an Arduino Uno microcontroller. The PIR sensor detects rat presence within a 5-meter range, transmitting this information to the Arduino Uno. In response, Arduino activates a buzzer to emit ultrasonic waves at frequencies specifically chosen to repel rats. The device also includes an LED as a visual indicator and an LCD for a real-time status display. The design incorporates jumper cables and a breadboard for assembling the circuit, with additional components, such as a potentiometer and battery connectors, for efficient operation. The effectiveness of the device depends on the precise programming of the Arduino, which controls the activation and intensity of ultrasonic emission. This innovative approach offers a noninvasive, environmentally friendly alternative for managing rat infestations in various settings.

Abstract

ABSTRAKPenelitian ini membahas mengenai penerima gelombang extremely low frequency (ELF) untuk pengolahan akuisisi data gempa bumi. Penerima ELF dirancang menggunakan operational amplifier (Op-Amp) dengan masukan takmembalik. Sinyal yang diterima oleh antena diteruskan ke penerima ELF yang terdiri dari preamplifier dan amplifier untuk proses penguatan, serta filter aktif orde 2 untuk menekan sinyal di atas frekuensi cut-off sebesar 50Hz. Karakterisasi penerima ELF dilakukan dengan mengamati perbandingan level tegangan sinyal keluaran terhadap level tegangan sinyal masukan, sensitivitas, serta bentuk sinyal keluaran dari penerima ELF dalam domain waktu. Hasil simulasi menunjukkan bahwa penerima ELF menghasilkan penguatan sebesar 60,8dB dengan sensitifitas tinggi untuk level sinyal masukan di bawah -30dB yang mampu memenuhi level sinyal untuk pengolahan akuisisi data.Kata kunci: extremely low frequency, penerima ELF, operational amplifier, filter aktif, gempa bumi ABSTRACTThis research presents extremely low frequency (ELF) receiver for earthquake data acquisition processing. The ELF receiver is designed based on non-inverting operational amplifier (Op-Amp). The signal received by the antenna is fed into ELF receiver which consists of preamplifier and amplifier for amplification, and second order active filter to suppress unwanted signal above the cut-off frequency of 50Hz. Characterization of ELF receiver is performed by observing the comparison of the level output signal to level input signal, sensitivity, and ELF receiver signal output in time domain. The simulation results show that the ELF receiver has gain of 60.8dB with high sensitivity for low level input signals below -30dB that is able to meet signal level for data acquisition processing.Keywords: extremely low frequency, ELF receiver, operational amplifier, active filter, earthquake

Abstract

The grounding system is very important in a building electrical installation. The socket is an electrical installation component that functions as a power supply line to electronic equipment which in the PUIL 2000 rules must be connected to the building grounding system. As the installation age of a building increases, the grounding system will degrade. In this research, a grounding detector has been made at the socket to determine whether the socket is connected to the grounding system. In this tool there is a plug-shaped component that is mounted on a socket. From the test results, the tool can detect the voltage, leakage current and ground connectivity detection which is displayed on the LCD screen. The optocoupler sensor installed around the wheel can read the wheel rotation well so that the distance measurement data between the outlets has a good accuracy rate approaching 100%, namely 99.26%. The Arduino Mega 2560 Pro microcontroller manages the overall measurement data results and transfers the data to the memory card. The duration of use of this tool can be up to 10 hours, which is quite a long time to be used for the purpose of checking the grounding condition of a building with this tool.

Abstract

The increasing use of electrical energy is inversely proportional to the diminishing fossil energy sources. New and Renewable Energy  is one of the alternative energy that is being developed now. One of the energy used in the utilization of new and renewable energy is wind energy. In this study, we will discuss the manufacture of blades made from Expanded Polystyrene (EPS) Foam which is intended for wind turbines at low wind speeds. The use of this material is used and is able to form a blade with a weight of ± 300gram. This blade uses an Inverse Tapper type blade, which is a blade with an enlarged geometry at the tip, this geometry has a large surface so that it can receive more wind so that it can rotate at low wind speeds. The design and manufacture of blades is carried out using Aeolus ASP software which is open source on several analysis features and serves to determine the performance of the blades as well as to analyze aerodynamics and optimization of the shape of the blades designed to use Blade Element Momentum (BEM). This blade is capable of producing a voltage of 12.09 V. In the process of making the blade using wire cut to create geometry with National Advisory Committee for National Aeronautics (NACA) 4412 airfoil. The blade uses layers of balsa wood and monocote plastic sheets, and uses wood plywood as the base of the blade.

Abstract

Penelitian ini menggali efektivitas sistem bioflok dalam budidaya ikan lele (Clarias sp.) sebagai metode untuk meningkatkan efisiensi pakan dan menjaga kualitas air. Kelompok tani Tunas Tani II di Desa Way Huwi, Kecamatan Jati Agung, Lampung Selatan, menjadi fokus penelitian ini. Sistem bioflok dipilih karena memiliki potensi untuk mengurangi biaya pakan dan meningkatkan produktivitas. Kolam bundar dengan diameter 2 meter dan tinggi 1 meter, dilengkapi dinding wiremesh dan atap fiber transparan, dirancang untuk memaksimalkan kondisi pertumbuhan bioflok dan melindungi ikan dari variasi kualitas air akibat hujan. Benih ikan lele yang berukuran 5-7 cm ditebar sejumlah 2000 ekor dan diaklimatisasi untuk memastikan adaptasi yang optimal dengan lingkungan bioflok. Formula bioflok yang terdiri dari probiotik, molase, dolomit, garam, dan tepung terigu, diaplikasikan selama 5-10 hari untuk mematangkan bioflok. Pemberian pakan, dimulai tiga hari setelah penebaran ikan, diotomatisasi melalui mikrokontroler dengan interaksi SMS gateway, menghasilkan pengurangan pakan sekitar 30-40% dibanding metode konvensional. Keberadaan bioflok sebagai sumber pakan tambahan menjadi faktor utama dalam penghematan ini. Pemantauan berkala dilakukan untuk menilai adaptasi ikan terhadap perubahan pH dan kualitas bioflok, yang terindikasi dari perubahan warna air dari coklat ke hijau, tanpa indikasi negatif seperti bau.
