Growth of LiTaO3 film on a type-p silicon substrate (100) was conducted using the Chemical Solution Deposition (CSD) and spin coating methods at a speed of 3000rpm for 30 seconds. The film on the substrate was then heated at 850(o)C for 15hours. The resulting film was then characterized for its sensitivity value. The film was utilized as a light sensor to read changes in light intensity to monitor lighting status in an arduino uno-based energy-saving automatic light prototype. Previously, the output of the film in the form of an electrical voltage was strengthened using a voltage amplifying circuit (OP-Amp). The energy-saving automatic light prototype was manufactured in two conditions, an automatic condition (with assistance from an infrared passive sensor and real time clock) and a manual condition (with assistance from a GSM to control the lighting and LiTaO3 film as a light sensor to monitor the lighting status). In the automatic condition, the assessment of the infrared passive sensor's sensitivity was conducted at distances of 0m, 0.5m, 1m, 1.5m, 2m, 2.5m, and 3m at angles of 0(0), 30(0), 45(0) and 60(0) (the source of motion was human movements). The real time clock was used to regulate the infrared passive sensor activation time (7 a.m to 5 p.m Western Indonesia Time). In the manual condition, when entering manual time (outside the 7 a.m to 5 p.m Western Indonesia Time range), to be exact, the GSM would send a message containing the duration of the lighting usage and the cost of the lighting usage. Activation of the lighting was conducted by replying to the message with the code #1 to turn on the lighting and #0 to turn it off.

Indonesia is one of the many countries with one of the most frequent earthquakes. Generally, in Indonesia earthquake damage level measurement is conduct by direct observation. However, the vibration intensity level of an earthquake could result in different levels of damage. Hence, a damage intensity scaling system plays important roles as measuring damage impact caused by an earthquake. Therefore, in this paper we proposes a design and development of a low-cost damage intensity scaling system based on microcontroller and microcomputer. The proposed idea is to record the damage level intensity data, distribute a valid data, and send an early warning if the earthquake damages is severe. This system hardware design utilizing MPU6050 Accelerometer sensor and a potentiometer as a vibration detector. This system use Telegram API and MQTT protocol to send sensors data to end user. The results of the experiment shows that our system has an average 3.17% of difference with the more sophisticated system owned by Meteorology, Climatology, and Geophysics Agency (BMKG) of Republic Indonesia.

This paper presents and implements an unauthorized object detector using ultrasonic waves. Ultrasonic refers to the waves with frequencies over 20 kHz. It is insensitive to human ears having audible perception range of 20 to 20 kHz. Thus, ultrasonic waves are useful for distance measurement in driverless cars. The distance can be measured by using two techniques;pulse echo and phase measurement methods. In this work, pulse echo method is considered where the target is detected via 'non-contact' technology. The Ultrasonic Module keeps monitoring and checks the echo reflected back by the entity to display the exact angle and distance on the screen. The novelty of this work is the development of an alert system that not only detects the target but also measures and displays its exact distance. PROTEUS software has been used for simulation. Hardware is also developed and tested to detect any entity in the prescribed range.

The main objective of this paper is to design and implement a remote sensing based home automation system using arduino uno Kit as a main controller for this scheme. The proposed system has two operational scenarios. The first scenario is to control the home devices from anywhere by using a smart phone with remote sensors and internet technologies controlling by the user, it is named a manual-scenario. The second scenario is to monitor and control the home devices by an automatic management between the remote sensors and the main controller 'arduino uno Kit', it is called an automatic scenario. To make and easy deal for a user the Matlab GUI platform is designed as a good interface to control and monitor the system. The proposed system is shown to be a simple, cost effective and flexible that making it a suitable and a good candidate for the smart home future.

Aim of this paper is to discuss about power quality of the AC system, which has become a great concern due to the rapidly increased use of inductive loads, electronic equipment (Linear and Non linear load). We are wasting a part of the electrical energy everyday due to the lagging power factor in the inductive loads which is used in the system. Hence, there is an urgent need to avoid this wastage of energy, lower power factor and reactive power results in poor reliability, safety problems and high energy cost. The power factor of power system is continuously changing due to differences in the size and number of the equipment being used at a time. This makes it challenging to balance the inductive and capacitive loads continuously. Many control methods for the Power Factor Correction (PFC) were proposed. This paper presents a computationally accurate technique to design and development of a single phase as well as three phase power factor correction, reactive power and THD compensation using arduino uno micro-controlling chip. The hardware implementation is developed by using arduino uno board.
