Abstract

The Covid-19 pandemic in 2020 has a significant impact on all countries' social and economic conditions, including Indonesia. It is fitting that social and economic changes also affect the transportation sector. The value of economic benefits in one public facility operation also depreciated due to the economic recession. One of the variables that can be reviewed is the time value of public passenger transportation users (AUP) to measure how much depreciation has occurred. This study specifically for travel is learning, using the bus mode Batik Solo Trans (BST) Corridor 4. Development of scenarios for questionnaires with stated preference methods, using the choice mode between motorbikes and AUP as an option, and the mode utility is approached with the equation multiple linear regression. The results of the analysis show that the time value of the user in the fleet is IDR 274.67 / hour for a distance of 8.35 km and the Time Value for a distance of 13.0 km = IDR 240.82 / hour with a Value of Activity (VoA) which is close to zero because the activity in the fleet has no financial value. This time value is considerably smaller than the AUP time value with the same intention of trip, studying, which was analyzed in 2015, which was IDR 4,708 / hour.

Abstract

The solar powered DC drive for a rickshaw is an automobile that uses solar energy to drive a DC motor, which in turn move a rickshaw. Due to the challenge of global warming, it has become necessary to make use of power sources that are environmentally friendly or renewable energy. Solar energy is used as the energy source in this design because it is cheap, clean and readily available during the day. This paper employed the use of solar PV which converts the solar energy into electrical energy. The electrical energy generated by the solar PV comes in the rated value of 12 V or 24 V which increases or decreases beyond this rated values depending on the sun intensity. To make use of the varying solar PV voltage, there is need to either buck (stepdown) or boost (step up) or buck-boost (stepdown-step up) the PV voltage to a constant voltage value. Since 12 V DC drive is used, it is required to step up or step down from the voltage range of 10 V to 25 V to 12 V via a buck-boost converter to power the 12 V DC drive. The DC motor control was implemented by embedding the functions of vehicle control in the system. The functions are; run, stop or break, left and right. This function makes the DC drive to control the rickshaw as vehicle. The results shows that rickshaw can be control and driven as a vehicle using solar energy.

Abstract

Network security is now increasingly needed in the era of the industrial revolution 4.0. As technology grows, cybercrimes are becoming more and more common, including attacks on a resource. At this time, honeypots are also widely used by large industries for network security, besides that honeypots are also useful for them in developing intrusion and preventing systems. Honeypots are usually used in a virtual environment, they will stimulate a fake system to capture data packets on the network and be analysed offline later for all threats and attacks. This propose of this paper is to detect and prevent building attacks from computer network attackers using an android application. This application can monitor an attack on the server by installing a honeypot tool into the server as an attack detector, then the honeypot log is used as a Rest API using Django framework with MongoDB database. this application can find out if there is an attack on the server, and can block the attacker's IP address.

Abstract

Autism has a very wide range that influences people, specifically children in general. Usually, it affects a child’s social interaction, communication, behaviors, and interests. Providing a complete device for treatment which is planned to be used by kids with autism needs to be taken into consideration. There is no software available that will adhere to the main areas of autism. The development a multidimensional software that focuses the main areas of kids with autism was a specific goal that the paper is being addressed. It is planned from the viewpoint of several specialists: more particularly speech therapist, occupational therapist, Special Education (SPED) educator and an Applied Behavior Analysis (ABA) specialist. The specialists’ focused objectives were lengthily included into the planning of the software. The development of an application for the young with autism that would completely attend to all the main areas that are initiated by autism and serves as an addendum to treatment is the primary goal of the study. Interviews from, speech therapist, occupational therapist, SPED teacher, ABA therapist and a SPED therapist will serve as a basis and the prototyping methodology for system development. With the implemented system, the intended users gave an approval on the application to be integrated in the teaching of children with autism. Suggestions on the improvement of the application comprises of including video recording for API 22, implementing the system in the iOS environment, and concentration on older autism cases were recommended.

Abstract

Tourism is one of the sectors that have been hit hard during the current Covid-19 pandemic. However, in 2021 the tourism sector is slowly rising marked by the number of tourist attractions that are starting to open to the public with the implementation of strict health protocols. However, in practice there are still many cases of violations of health protocols in various tourist attractions, ranging from the undisciplined use of masks, not keeping a distance (social distancing), and the absence of setting the ideal number of visitors during a pandemic like the current one. Managers of tourist attractions tend to ignore restrictions on the number of visitors due to the absence of an management system to run. There needs to be an application that can inform the condition of visitors to tourist attractions in real-time so that people have self-awareness of their personal health so that people can make early plans before traveling. In good governance, this application contributes to controlling the risk of Covid-19 transmission originating from crowded centers (tourist spots). The government can easily monitor the distribution of tourist visitor density in the area so that it can then be used as a basis for carrying out policies and handling in the field. This study proposes the development of an application platform (software and hardware) monitoring the density of visitors to tourist attractions using the concept of object detection based on image processing and deep learning. The integration of hardware with web-based software will provide information on the density of visitors to tourist attractions that are easily accessible to the public so that they are expected to contribute to the handling of the current Covid-19 pandemic.

Abstract

Based 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 post

Abstract

Lack of river and watershed management will cause problems and disasters. One of it is the flood that can cause physical, social and economic loss. So countermeasures or flood anticipation are needed by using the Early Warning System (EWS) to provide early information if a flood is going to occur. This study uses five input indicators: temperature, humidity, water discharge, water surface altitude and rainfall data that will produce output in the form of notifications and alarms for the Early Warning System (EWS). Then the input and output data configuration will be processed using a Backpropagation Neural Network. Data used is data recorded in real-time on the research object for two weeks with the composition of training and testing data with a percentage of 80% and 20%. The best backpropagation neural network model used has the input of 5 neurons layer architecture, 15 neurons as the hidden layer and three neurons as the output layer. The flood prediction result uses the Backpropagation Neural Network method, has an RMSE score performance of 2.16e-21 and a percentage success testing system of 91.33%. It shows that the model has an excellent accuracy level.

Abstract

Painting 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.

Abstract

The 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. Key words : Agriculture, Effluent, Environment, Water Treatment, Zeeland.
