Nowadays safety becomes an increasing important factor in developing cars. Measures come in the form of physical strengthening and diagnostics improvement of the car. One way to improve the safety of a car is by implementing a car parking assistance. Although it already becomes a standard feature in some cars, the additional charge for the customers is still considerably high. This condition motivates the author to develop and implement a car parking assistance with affordable price and suitable for any types of car. The proposed system utilizes the ATmega16 Microcontroller and an ultrasonic sensor. The ultrasonic has a transmitter that produces a pulse in every 62.5 ms, and a receiver that detects the reflected pulse. The time of wave travel and thus the distance can be deduced. An LCD and a LED indicate the presence of object in front of the ultrasonic sensor. The resulting prototype proved that a car parking assistance can be made with low cost. Besides, it can be installed in any car with minimal adjustment.

Machine cost is one of the components of production cost. Accurate record of machine usage time is thus crucial to obtain accurate production cost calculation. Besides, machine usage time can be used as parameter to assess the performance of the machine operator. Furthermore, the data can be used as input to the machine’s maintenance and reparation plan. The author is motivated by the current problems found at Akademi Teknik Mesin Industri (ATMI) Cikarang, where it is still possible to use one machine simultaneously by more than one operator. This causes inaccuracy in calculation of machine usage time and production cost. In this paper, the author proposed a design of device to record detailed data of shop drawing and machine usage time. By the use of this device, a certain machine will be activated and deactivated by using RFID technology, with the whole system controlled by Arduino Mega 2560 microcontroller. Furthermore, the shop drawing and machine usage time will be able to be accessed through a Windows-based interface application, implemented by using Visual Studio. A database is also made available by using Microsoft Access. The use of the proposed device makes possible of accurate measurement of production time efficiency and machine operator performance. Through this improved accuracy, further analysis can be made in order to achieve production improvements in planning, process, and maintenance.

Vision impairment has been common phenomena in this day and age. Many people suffer from this impairment with only a few technological supports to help them in daily life. This project created prototype to help people with vision impairment navigating through space. Built in the form of a belt, this project uses Ultrasonic sensor to detect the surrounding object. It uses three ultrasonic sensors attached to the front, left, and right area of the belt. Whenever an object is detected near any of these three areas, buzzer will be ringing. The buzzer is set in three different tones such that the wearer knows which side of the belt the object is.

Perancangan Detektor Kebocoran Gas LPG Berbasis Arduino yang Terhubung dengan Smartphone Ade Mutaqin; Erwin Sitompul

LPG (Liquefied Petroleum Gas) has become the fuel for cooking for most households in Indonesia. The use of LPG for cooking requires high level of caution, due to the danger that may arise from gas leakage. If the molecules of flammable LPG gas are present in the air at a certain concentration and there is a triggerring factor in the form of flame or sparks, explosion and fire may occur. To prevent disasters caused by a LPG gas leakage, the author proposed an Arduino-based LPG gas leak detector (GLD). The GLD is equipped with a MQ-2 gas sensor, capable of measuring the LPG concentration in air in units of parts per million (ppm). Based on the measurement result, the GLD provides an early warning of LPG leakage through 3 condition levels: Normal, Alert, and Danger. Each condition level is characterized by the activation of LED indicators, a miniature air circulation fan , and a buzzer. Alert warning is released when the sensor reads more than 400 ppm (2.05% of LPG Lower Explosive Level). Danger warning is given at 800 ppm (4.10% of LPG Lower Explosive Level) or higher reading. An HC-06 Bluetooth module creates a wireless connection between the GLD and a smartphone. Through an application created on Blynk platform, the smartphone can monitor the LPG concentration at a distance of 10 m from the GLD. The GLD is tested and succeeded to detect gases coming from an LPG cylinder and from a gas lighter. The GLD also runs perfectly for the designed early warning scheme.

Door Security System Using e-KTP RFID Reading and Passive Infrared Sensor Mohammad Adrian Faisal; Erwin Sitompul

A door, as a barrier to limit an access between two spaces, requires a security measure to ensure that only privileged people may pass. In this paper, a door security system using Radio Frequency Identification (RFID) and Passive Infrared (PIR) sensor is proposed. This security system utilizes an electric door lock and an e-KTP (Kartu Tanda Penduduk elektronik/ electronic Indonesian Identity Card) as the key. A sequence of numbers can be read from an e KTP by using an RFID reader. This sequence is unique, making an e-KTP suitable to be used as a key. Furthermore, the door security system is equipped with an alarm. A PIR is used to detect motion, and the alarm will sound if someone passes the door while the alarm is still in active state. The Arduino Mega microcontroller board is used to organize the whole system, consisting the aforementioned reader and sensor, along with two push-buttons, a buzzer, and a solenoid door lock. The system is realized into a prototype in the form of door miniature. A list of scenarios is played through to the system. Only authorized e-KTPs can be used to unlock the door and deactivate the alarm. The door security system successfully fulfils the objective to improve the security level of a door lock mechanism by utilizing an e-KTP as a unique RFID key and by featuring a PIR-integrated alarm.

Retrofication of Cascade Control System and Implementation of Human Machine Interface in A Water Treatment Plant Erwin Sitompul; Dicky Kuswira

In Indonesia urban area, due to low water distribution pressure at day, many inhabitants who live far from water distribution center get their fresh water share only at night or sometimes never. In order to ensure even distributed fresh water, there is a certain pressure that needs to be maintained. On a real technical project, an advance cascade controller will be installed in a water treatment plant to control multiple pump for maintaining distribution pressure. Furthermore, a corresponding Human Machine Interface (HMI) will be installed for easier daily monitoring and operation. Measurement data shows improved performance of the system, with only 0.02 bar of pressure error and better load distribution among the operating pumps. Keywords: water treatment plant, cascade controller, Human Machine Interface
