Abstract

The number of companies in the industry, as well as the current economic conditions, have created intense competition between companies. One of the important activities of a company is distributing goods from a warehouse to several agents so that the distribution of goods can be done easily and quickly. National Pure Milk Company is based in Salatiga. There are various flavors of pure milk stored in the form of a cup and a pack that will be distributed to each destination. Each cup and pack has data in the form of mass, volume, destination (distance between the destination location and the warehouse location), and the time when it must be dropped. All items of pure milk will be delivered by 4 truck vehicles with different types. Each vehicle has a mass capacity, volume capacity, mileage capacity, trip duration capacity, and trip number capacity. All the data of the pure milk that distributed must not run over the capacity of the vehicle. In this research, Particle Swarm Optimization (PSO) Algorithm can be modified into the discrete PSO Algorithm to determine the shortest distance of the route and Genetic Algorithms can be modified to determine the exact composition of goods on each vehicle. The optimization problem is limited by the condition that each item is delivered at the same time interval.

Abstract

Covid-19 is an infectious disease that has plagued the world since the end of 2019 until now. In Indonesia, the Covid-19 case is quite large, so the government requires everyone to get the vaccine. However, the implementation of the vaccine has not been implemented properly. By taking advantage of the current times, a web-based application was built that can track the circulation of vaccines and contain information about the authenticity of vaccines. The development of this application uses an Agile methodology that focuses on the Extreme Programming (XP) model.  Extreme Programming (XP) is a method that can simplify several stages of software development. The results of testing conducted by Blackbox testing show that all existing system feature or functionality have run as expected.Keywords: Agile, Covid-19, Extreme Programming, Web-based Appliaction, and Vaccine. Covid-19 merupakan penyakit menular yang menyebar di seluruh dunia sejak akhir tahun 2019 hingga sekarang.

Abstract

In general, a robot is defined as a mechanical device used by humans to ease human work. Robots are usually used for difficult and dangerous tasks. One example of its use is a firefighting robot that replaces human tasks in extinguishing fires. The firefighting robot is on duty to find fire spots in a city then extinguishing them. To be able to put out a fire, the robot must implement an efficient program in finding and determining the shortest path to the location of the fire and then put it out. For this reason, the robot is equipped with proximity and fire sensors to detect the presence of fire. The design is made with a three-step program that is designing needs of robot control, robot control mechanism scheme preparation and implementing an algorithm for making program syntax. The Brute-Force Algorithm can be implemented to indicate the presence of a hotspot signal and the backtracking Algorithm is implemented to find the shortest path to the hotspot location. This paper discusses the use of a brute-force algorithm and a backtracking algorithm in a firefighting robot program to make the fire search process more efficient. The results show that from 8 input fire points, the firefighting robot is able to find all the points within 3.12 seconds with 13 times trial. In its application, the writer used Visual Basic 6.0 in the firefighting robot program.Keywords: Firefighting Robot, Brute-Force Algorithm, and Backtracking Algorithm.Secara umum robot didefinisikan sebagai suatu alat mekanik yang digunakan oleh manusia untuk mempermudah pekerjaan manusia.

Abstract

Implementation of vaccines, mosquito repellents and several Wolbachia schemes have been proposed recently as strategies against dengue. Research showed that the use of vaccine and repellent is highly effective when implemented to individuals who are in area with high transmission rates, while the use of Wolbachia bacteria is strongly effective when implemented in area with low transmission rates. This research is to show a three-strategy combination to cope with the dengue using mathematical model. In dengue mathematical model construction, several parameters are not yet known, therefore a genetic algorithm method was used to estimate dengue model parameters. Numerical simulation results showed that the combination of three strategies were able to reduce the number of infected humans. The dynamic of the human population with the combination of three strategies on average was able to reduce the infected human population by 45.2% in immobility aspect. Furthermore, the mobility aspect in dengue model was presented by reviewing two areas; Yogyakarta and Semarang in Indonesia. The numerical solutions showed that the trend graph was almost similar between the two areas. With the maximum effort given, the combination control values decreased slowly until the 100th day.

Abstract

Micro, small and medium enterprises (UMKM) is one of the important aspects to support the improvement of the economy in Indonesia. Zee Mart’s business is one of the UMKM shop in Pematang Siantar City with sales and purchase transaction activities for supplies. The purpose of this study is to predict the sales of Zee Mart store goods in the coming month using the adaptive response rate single exponential smoothing (ARRSES) method. ARRSES is a method with the advantage of having two parameters, alpha and beta, where alpha will change every period when the data pattern changes. The dataset obtained will be pre-processed through data selection, cleaning, and transformation. The best beta is determined based on the level of accuracy calculated using the mean absolute percentage error (MAPE). Model development using the ARRSES method will produce forecasting percentages and errors for each product using MAPE. The number of sales data is 23,092 before preprocessing and 23,021 after pre-processing, with the total quantity of goods sold being 149,764 of 1,492 products. The results obtained using sales data 23,021 show the lowest MAPE value of 9.85 at the best beta of 0.6 with the highest accuracy of 90.15% and the model is implemented into a web interface.

Abstract

The payroll system is very influential on a company's workers' welfare in achieving company goals. Appropriate payroll will build morale for the workforce so that they can advance the company through the work ethic and professionalism of the crew. The salary calculation system for employees must be adjusted to several criteria, such as their city and job role. Long experience can also be used as a calculation criterion in providing salary. For this reason, an approach is needed to provide a decent and good salary prediction for the company's consideration. One of the models commonly used in making predictions is linear regression. Linear regression is a model that calculates the relationship between two variables with independent values and bound data. This research develops a system by implementing a Linear Regression algorithm to predict the salaries of IT employees in Java. The model that has been created is then built using the Python language and implemented into a website-based visualization form that is easy to understand with Streamlit. The modeling results were tested and gave an MSE value of 8240258.48. This research is expected to be a reference in research related to this topic in the future and can be used by companies that have difficulties in determining employee salaries

Abstract

Games are a means of entertainment that great demand by the community. Besides games as entertainment, games can also practice thinking skills to find solutions. A game that contains elements of artificial intelligence requires algorithms in its implementation. One type of the game is Maze Game, where players are required to find a way out of the maze. Backtracking algorithm was chosen to solve this game. This algorithm works recursively to solve problems by finding possible solutions. If the path being traced is not the right solution, it will be backtracked and traced to other paths. This solution will not be ignored or deleted. But if the path taken is right, it will continue to check the next path until the player reaches the final solution.

Abstract

Sipituhuta Village is one of the villages in Pollung District which has commodities in the agricultural sector. In 2016 a farmer group called the Maduma Tani Group was established as a means for sustainable agriculture to increase income. This farmer group provides farming tools that can be borrowed by farmers. However, the lack of information about the availability of farming tools and education on agricultural processing causes the process of borrowing tools and seeking agricultural processing education is still manual. The use of the website is one of the solutions in the field of information technology that helps increase farmers' knowledge in solving agricultural problems they face and borrowing farming tools in Sipituhuta Village. The development of this website uses the prototyping method, where this method is very suitable for building small-scale and customized websites that are created based on certain requests and needs. Website development using the PHP programming language, Laravel framework, and MySQL Database Management System (DBMS). Some of the features that have been successfully developed include lending tools, viewing history of tool lending, viewing education, viewing farming projects, viewing notifications. The result of this activity is that farmers in Sipituhuta Village can easily find information about agriculture and borrow farming tools. Website testing is done using the black box method. The test results show that the website that was built has been successfully running according to its function.
