ELEMENTS OF COST AND SCHEDULE OVERRUN IN CONSTRUCTIONPROJECTS
No full textThe cost of a basic upgrade to this wonderful piece of study is typically expressed in necessary units like earned dollars. The economic activity necessary to ensure that the building projects are sufficiently finished within an approved budget is properly included in the Project Cost. Although having more practical experience in construction management, cost and schedule overruns still play a significant role in many projects. Modern literatures are studied back-to-back and divided into two parts, which costs money for particular projects, overrunning of schedules in construction projects. The main study establishes that price increase causes cost and schedule overruns. For all intents and purposes, any client who is interested in facilities in the manufacturing sector is complete in terms of scope, timing, and cost. These studies have been published under a creative commons permission with the express purpose of carefully controlling causes. Uniquely required, necessary materials and cutting-edge products have a direct impact on building projects' schedule and expense overruns. The published study clearly shows the lack of essential maintenance of the project equipment, decreased working class productivity, barriers in bill declaration, poor preservation of the useful tools, and other external factors slowly constitute the significant factors that may properly conduct the project at a typical cost over the period
Control System for Swerve Drive Wheeled Automated Guided Vehicle with Ultra-Wide Band Local Positioning System
No full textControl system for Automates Guided Vehicle (AGV) is used to control the motor movement so that the AGV can go to a position in certain speed and orientation. Discussion in this paper is about how to control 4-wheel swerve drive-based AGV. Mechanical structure of each wheel is built in such a way that the wheel can move forward / backward and the orientation can be adjusted while moving. Each wheel requires two BLDC motors to drive and to steer the AGV. In this project, the power each motor is 200W which is drove and controlled by Syntron LS20530G motor driver that connected to a computer via CAN-bus. An Ultra-Wide Band (UWB)-based Local Positioning System (LPS) is used to monitor the position of the AGV as well as a guide for non-physical paths so that AGV moves according to a given path virtually. The experimental results show that AGV can move in a straight line with a speed of 50m/min. Wheels can also be steered according to a certain angle so that the AGV can move towards the destination point. The steering angle of each wheel is between -135 degrees to 135 degrees
Monitoring Automatic Color Walln Paint With Blynk Application
No full textPainting is a process of giving color to an object's surface which aims to beautify, strengthen and protect the object. Today, the need for paint continues to increase with the demand for various colors, generally sellers or painters mix several primary paint colors to produce a variety of colors. In practice, many of them still use the manual method, this is considered less efficient and less practical. This research produces an Automatic Primary Color Wall Paint Mixing System Using the TCS34725 Sensor. The paint pigments used in this system are red, green and blue pigments. The TCS34725 sensor is used as a color detector for reference objects with red, green and blue data formats. The results from the TCS34725 sensor readings are then processed by the NodeMCU8266 microcontroller to control the water pump to issue bubble pigmentation for wall paint based on the PWM value or color code with a time lag of every 100 milliseconds of bubble. Next, mixing the primary color pigments for wall paint and white wall paint will be stirred using a 12VDC motor until all the primary color pigments and white wall paint are evenly mixed. Furthermore, the TCS34725 sensor is reused to check the results of the mixing of the primary color pigments for wall paint and white wall paint. The results of this study note that the TCS34725 sensor can be used as a paint color detector by looking for the RGB value on the color card. From the results of the water pump test, the accuracy value for the red water pump is 62.21%, the green water pump is 65.28% and the blue water pump is 61.29%. From the results of the mixing obtained an average accuracy of 62.93% by taking sample data as much as 10 times mixing the primary color pigment with white wall paint.Kata kunci: Node MCU8266, RGB, Cat tembok, PWM, Warna primer, Water pump, TCS34725, Bubble, Pikmen color
SELECTION OF ZEELAND’S MUNICIPAL EFFLUENT REUSE TECHNOLOGY FOR AGRICULTURE: PERSPECTIVE FROM DEVELOPING COUNTRY
No full textThe water demands for agricultural purposes are increasing along with the population growth. Unfortunately, the water source is not sufficiently available nowadays. Furthermore, the quality of available water is more deteriorated due to the contamination from many sources such as households, industrial areas and other activities. Water board Scheldestromen handles 16 wastewater treatment plants located in Province of Zeeland in The Netherlands. The total production of treated effluent water from 16 wastewater treatment plants is 50 million annually. Quality of the effluent is relatively good, however, some potential risks related to the number of pathogenic microorganism and some trace metals are still there. The treated effluent is mostly discharged to river near to the treatment plant. The high amount of effluent discharge would potentially to be re-used for fulfill the demand for agricultural water. Therefore, this study aims to evaluate the feasibility of treated effluent from one of Walcheren wastewater treatment plants located in Ritthem, Province of Zeeland. This study uses the method of Multi Criteria Analysis (MCA) for looking the best way to reuse the effluent for agricultural purposes. The MCA questionnaire was developed based on the thorough literature review of effluent reuse. There are 6 criteria that need to be weighted and 6 scenario alternatives that need to be scored for the MCA questionnaire. The result show that the effluent water contained pathogenic bacteria (E.Coli) and some trace metals (Ni and Cu) more than suggested by FAO standard. Hence the most preferred technology is combination between closed conduits and UV system, with weighted score 0.78 while others had less weighted score compared to the selected one.

Availability of Silica in Dusts at different operations locations in Limestone Quarry in Ewekoro, Nigeria
No full textThe dusts from mines and quarries have been reported to induce respiratory problems among mineral workers. This study was carried out to investigate the availability of free silica in the dust from different parts of the quarry with different activities. The blasted, boreholes and stacked sites were investigated. The collected dust was analyzed using an X-Ray analyzer. The result shows that the highest free silica content (mean of 22.279%) was found in dusts from borehole, followed by blasted parts (17.195%). The stacked shows the least mean (7.566%). The statistical analysis carried out on the result using SPSS software shows that there is statistical independence of the dust from different sections of the quarry, meanwhile the values of the means are environmentally significant. The recommendations were made on how to control the negative effect of the free silica in every aspect of the quarry with emphasis on borehole drilling section
Development of Fish Distribution Information System for Digital Virtual Assitant based on Harvesine with LoRA Node
No full textThe pressing issue of suboptimal and inefficient traditional fishing practices among local communities. Traditional fishermen often operate with inadequate equipment, resulting in less-than-optimal fishing outcomes. In this context, the lack of modern tools and techniques hinders the effectiveness of fish capture. Addressing these challenges is crucial for enhancing the productivity and sustainability of traditional fishing practices. The study aims to develop an advanced Fish Distribution Information System tailored for a Digital Virtual Assistant using the Haversine method and LoRA nodes. This system provide instantaneous, location-specific details about fish distribution and involves designing a data logger serving as repository for travel histories, utilizing a website as the user interface interfacing with a Leaflet map in a Geographic Information System (GIS). The Haversine method is employed for precise distance computations between LoRA Gateway, information about fish distribution, and unfavorable weather conditions within the specified area. the resukt show that The distance displayed on the website with the haversine method with excel calculation comparison produces an error calculation of 0.157%, while the percentage error for GPS latitude accuracy is 0.000116% and longitude percentage is 0.000002%. RSSI performance at LoRA ranges from -57dBM at a distance of 50m and -121dBM at a distance of 1500m

Vessel Safety Monitoring System (VSMS) Based on LoRA for the Safety of Indonesian Traditional Fishers
No full textBased on data obtained from Indonesian fisheries statistics, over ten years, it is known that 90% of the fishing fleet in Indonesia is dominated by fishing vessels under 30 GT. Generally, these vessels are not equipped with the calculations of the shipping architect or planning drawings. the large percentage of shipping disasters or vessel accidents in Indonesia, including fishing vessel accidents, is caused by several factors: 43.67% due to human error, 32.37% due to nature, 23.94% due to technical factors. Accidents due to bad weather cannot be avoided during fishing operations. However, with the quality of human resources and technical factors that have improved, it is hoped that vessel accidents can be avoided or minimized. According to the Global Maritime Distress and Safety System (GMDSS), vessels with the IMO standard are already based on satellite communications. Vessels required to use the GMDSS standard are vessels with a size of 300 GT and above. We develop a Vessel Safety Monitoring System (VSMS) which has a lower cost, which can be used to determine the vessel’s position and is added by using a distress button system such as the satellite-based GMDSS system. the communication from the coast guard post to the vessel uses the LoRA module based on radio frequency, although without pressing the distress button on the vessel, the device on the vessel will continue to send location, vessel's speed, and rpm to the coast guard station. If the distress button is pressed, the location will still be sent, the buzzer at the coast guard post will turn on, and the vessel's location can be seen on the local web server so that the coast guard post officers can immediately find out the coordinates of the vessel. It can minimize the time to search for the vessel's location because the vessel's coordinates are known. Based on the results of the Vessel Safety Monitoring System (VSMS) test, 10 data transmission from the vessel to the coast guard post can work on the land and the sea it can send nine types of data with 0 - 50 meters distance, it can send 1 type of data with a 0 - 100 meters distance, with an average delivery delay of 5 seconds. The amount of data and the delivery delay affects the working distance of the tool. The distress function or the danger signal requires data transmission for 0-15 seconds manually or automatically until the alarm goes off at the coast guard post since the vessel's danger signal is activated from the vessel to the coast guard pos
The 3in1 Robot Design for Medical Assistant on 2019-nCoV case
No full textCovid-19 (Coronavirus disease 2019) is a new coronavirus (SARS-CoV-2) that is known to have originated in Wuhan, China. It was found at the end of December 2019 with countries infected with the Coronavirus in more than 65 countries. According to WHO data as of the 4th of March 2020, the number of sufferers was 90,308 infected with Covid-19. In Indonesia as of April 14, 2010, people with Covid-19 were positive for 4,839, recovered 426, and died 459. In Indonesia, one of the ways to tackle the Covid-19 pandemic is by spraying with disinfectant liquid and delivering food or medicine to patients infected with Covid. -19 is still in close contact with a patient who is still likely to be infected from that patient. According to general guidelines in dealing with the Covid-19 pandemic, one of them is done by spraying disinfectants in several public facilities such as health clinics, government office, schools, bridges, parks, fields, and other public areas. However, sterilization is still done manually by health workers. This puts medical personnel at risk of being exposed to the covid-19 virus. Therefore, in this study, a multi-functional robot with a remote control equipped with an FPV camera was developed. The robot can be used to spray disinfectant, UV lamp-based sterilization, and deliver food and medicine to patients infected with Covid-19. From the test results, the teleoperation system can work well with a range of 30 meters indoors and 150 meters outdoors
