Abstract
The noticeboard is an essential thing in any establishment or association to convey data among the partners. In the occupied and quick-moving present reality, the traditional paper notice framework is tedious and not reasonable for brisk sharing of data. This exploration work aimed at designing an electronic scrolling display board on a specially designed Printed Circuit Board (PCB). The thought behind this undertaking is to furnish its clients with a basic, quick what’s more, dependable approach to set up a significant notification in a LED where the client can display messages to be shown directly on the LED unit from a computer to the microcontroller and also to give notification about anything at a particular moment to the targeted group or audience. This will significantly provide improved measures to the limitations and restrictions of conventional notice boards. The system is created with an ATmega 328P microcontroller from Atmel. The microcontroller showed all the usefulness of the showcase notifications required. The Display is acquired on a 2X (16X72) dot matrix display board, orchestrated on a cascaded specialized PCB designed with a Ki-cad schematic/design software suite for a wider view. An ideal instant message from a computer is sent utilizing Arduino IDE and HT1632 driver IC to drive these tremendous LEDs. The framework was tried to work as per the test message. This brilliant notification board can make the notification arrangement of an association much basic, quick and financially savvy and provide a limitation to an accident that can occur when sticking paper-based notification sheets.

Abstract
Tracing stolen cattle in the Lombok Tengah regency of NTB province is carried out by tracing footprints and waiting at certain location points which are considered as the route to be traversed or the final destination of cattle theft which is called “Ngendeng”. Ngendeng is carried out day and night from the time the livestock is declared missing until the livestock is found or the potential to be found is considered lost. The problem that occurs in Ngendeng’s activities is that it endangers the safety of life if there is a clash with thieves and a decrease in health for the people of Ngendeng. To replace the role of the community in doing Ngendeng, an Internet of Things (IoT) devices for image capturing was developed. The device can take a picture if someone passes through the front of the device then it is sent to the Telegram account of the District Police and the Community telegram account.

Abstract
Malaria is one of the dangerous diseases in the world. Despite it has been decreased every year, the number of patients for this disease is still reasonably a lot. Technical problems that arise in the malaria cases are due to malaria examination and diagnosis analysis, which are carried out manually. At the same time, there are still medical personnel scarcities in some rural areas including of some districts in Indonesia. Moreover, the required examination process demands accuracy and takes a long time. Thus, an effective solution is necessary to help parasitologist to reduce malaria cases. One of the alternative ways to solve those problems is by utilizing technology to assist medical personnel in conducting examinations and analyzing the diagnosis results. This research was conducted to reach this objective. In achieving this objective, an image segmentation approach for finding the Plasmodium parasites was developed. The proposed approach consisted of four stages, which are the pre-processing stage, the segmentation stage, the refinement of segmentation results stage, and the evaluation stage. This proposed method was performed on 25 digital microscopy images of the thin blood smear digital microscopic images. The experiment yielded a good performance with the accuracy, sensitivity, and specificity of 99.83%, 85.06%, and 99.90%, respectively. These results indicate that the proposed method has an outstanding performance in segmenting Plasmodium parasite and can be utilized as a preliminary project to assist doctors in examining or identifying the Plasmodium parasites location.

Published: February 2021

Abstract
A dental unit is a device for dental examination and treatment, including drilling, filling, cleaning and examination. In 2018, Basic Health Research Center Indonesia recorded the proportion of oral and dental problems of 57.6% and 10.2% of those who received services from dental medical personnel. Equitable distribution of dental health services at public health centers for the middle to lower-income community still faces a lack of facilities due to the dental unit’s high cost. Judging from the above problems, the author wants to make an economical Dental Unit but has entered into the standard of a dental examination. In designing the dental suction device and handpiece, this micromotor utilizes an LCD display as a pressure reading on dental suction, which has been converted by the MPX4115C6U5V sensor as well as the micromotor handpiece. There are up and down buttons for selecting the rotation speed from 1000 RPM to 25000 RPM. The tests carried out include testing the suction pressure at dental suction and testing the rotational speed of the micromotor handpiece. Based on the results, the sensor used as a pressure reader for the calibrator tool has the largest correction value of 0.36 KPa at -10 KPa pressure measurement, the micromotor handpiece testing has the highest error of 2.2% and the lowest error of 0.3. %. Thus, it can be concluded that the design of the dental suction device and the micromotor handpiece can be used in the examination of teeth and mouth as a saliva suction device and tartar cleaning.

Published: February 2021

Abstract
The construction industry is constantly changing due to market conditions and increased competition. The competition, in particular, has resulted in the need in better schedule performance for construction projects. Construction schedules are fundamental and challenging activities in the execution as well as management of construction projects. Besides, scheduling is an essential function of the project management since it provides a roadmap illustrating all the activities, milestones, and deliverables within a project to prevent any delays during the project’s commission as well as handover. In project management, delays have an adverse effect on the construction lifecycle and mainly arise from poor planning as well as forecasting techniques, insufficient knowledge on scheduling techniques, and inadequate or inefficient communication processes or technologies. The aim of this study is to identify the gap between scheduling theory and scheduling practices in reality of construction schedules in the UAE and its reduction methods in the practice. It will review existing literature to link schedule theory and good practices to illustrate the relationship between schedule problems and usage to recommend ways of improvements. A concise methodology stating the proposed research design and instrument is also provided.

Abstract
Hand-Arm Vibration Syndrome (HAVS) is a disorder caused by vibration of work tools that vibrate the hands excessively or above the threshold. The impact of Hand-Arm Vibration Syndrome (HAVS) over a long period of time causes damage to blood vessels, permanent sensory loss, bone damage and muscle weakness. One of the workers with the presence of Hand-Arm Vibration Syndrome (HAVS) is a hand tractor driver. To reduce vibrations received by hand tractor drivers that could potentially cause Hand-Arm Vibration Syndrome (HAVS), a tractor control device was built by implementing the Internet Of Things (IoT). The hand tractor control device developed utilizes an Android-based application as a remote control, an access point as a connector, an electronic circuit based on the ESP8266 MCU Node to translate commands from the android application into motion to move the main clutch lever to forward and stop, gas lever, and gear clutch to turn left and right.

Abstract
An x-ray machine is a medical device that is used as a diagnostic tool for patients. The conventional x-ray machine consists of a control system, high voltage and tube x-ray machine. The control system on conventional x-ray machines uses too many cables so it looks less efficient. Control of the x-ray machine must be carried out in the same room as the equipment so that it can endanger the radiographer when it will be operated, because the radiographer will be continuously exposed to radiation. Therefore, an x-ray machine control system is designed that is safe for radiographers when operated and efficient in the use of cables. This research method uses the Arduino application to change the conventional control system to wireless, with the aim of providing the radiographer’s safety because he operates the device from a separate room and does not face the x-ray machine directly. Current selection uses several contactors at each different current. The contactor is controlled by a microcontroller connected by a series of drivers. The process of selecting voltage, current and time is carried out on a Personal Computer (PC) connected to the controller via Bluetooth. The test is done by measuring the output voltage of the filament transformer using an AVO meter, then comparing it with the voltage calculation results obtained from the x-ray machine tube specifications. Based on the tests that have been done, it is found that the correction value is small and does not deviate much, which is 0.01 V when selecting mA 50 and 0.09 V when selecting mA 60. The x-ray machine can be controlled wirelessly using a PC with a distance 6 meters in conditions blocked by a 9 cm thick wall.

Abstract
The purpose of this research is to detect and store data on theft of mosque charity boxes using the Internet of Things (IoT) by activating short message notifications on smartphones and database servers through a web framework. The focus of this research is the use of Arduino R3 as a microcontroller that regulates the detection of theft of a mosque’s charity box with a passive infrared sensor HC-SR501, a magnetic switch sensor MC-38, and sending short message notifications and storing detection results to a database server. Arduino R3 is used as a microcontroller with a program that can be recycled using the Arduino IDE, while the HC-SR501 passive infrared sensor is used to detect human movement with changes in body heat, through infrared rays emitted by a Fresnel lens, then identified by the pyroelectric sensor made from gallium nitride (GaN), cesium nitrate (CsNO3) and lithium tantalate (LiTaO3), a change in heat temperature then activates the buzzer when a hot object is detected. Whereas the MC-38 magnetic switch sensor functions to turn on the buzzer when the mosque charity box is forcibly opened by a thief with a normally closed and normally open angle. The results obtained from this study are testing the MC-38 magnetic sensor has two working modes, namely normally close when the two beam blades fuse within a distance of < 3 cm, above a distance of > 3 cm, normally open, meaning that the conditions are not safe. While the test results of the HC-SR501 PIR sensor have the ability to detect body movements with a minimum reading distance of 30 cm and a maximum of 10 m, with LOW results if not detected and High if detected by human objects.
The effect of gradation on the mixed characteristics of HRS-WC using campurejo material

Published: February 2021

Abstract
Hot Rolled Sheet (HRS) is a type of hot asphalt mixture as a layer of the road surface that will transmit traffic loads to the layer below to the subgrade. To get good results, the mixture must be designed in accordance with the provisions in the specifications with due regard to the limitations of the limits. The purpose of this study was to determine the effect of gradation on the characteristics of the HRS-WC mixture using gaps. The asphalt content used for the top gradation test was 5.50%, 6.00%, 6.50%, 7.00% and 7.50%, the middle gradation was 5.00%, 5.50%, 6.00%, 6.50% and 7.00% while the lower gradation used asphalt content 4.50%, 5.00 %, 5.50%, 6.00% and 6.50%. The results showed that the use of Campurejo aggregate as seen in the results of the aggregate characteristic test can be used as a mixture for HRS-WC, however in the use of grading it is recommended to use a gradient closer to the middle grading. Likewise, the use of asphalt content uses a percentage of asphalt content above ideal asphalt content. The use of upper and lower aggregate grading results in cavities that are close to specification limits. It is feared that if it is applied in a field with a control that is not the same as in the laboratory, it will result in a cavity outside the specification. In addition, using a middle grading can optimize stability and minimize the use of asphalt.
