Abstract

Pada penelitian ini bertujuan untuk melakukan komparasi terhadap metode Naïve Bayes dan Random Forest dalam klasifikasi data pasien penyakit liver. Adapun data pengujian yang digunakan yaitu Indian Liver Patient Dataset (ILPD) yang diperoleh dari UCI Machine Learning Repository. Dataset tersebut memiliki 583 record data, 10 kriteria, dan 1 variable kelas serta dengan jumlah kelas sebanyak 2 kelas atribut, serta data set tersebut berjenis multivariate. Terdapat beberapa tahapan preprocessing yang dilakukan, antara lain normalisasi data yang diujikan, selanjutnya dilakukan analisis klasifikasi menggunakan metode naïvebayes dan random forest. Berdasarkan hasil pengujian yang dilakukan dalam memperoleh nilai akurasi perhitungan klasifikasi menggunakan Confusion Matrix, maka metode Random Forest memperoleh hasil yang terbaik yaitu dengan peroleh akurasi sebesar 70.60 % bila dibandingkan dengan Naïve Bayes yang hanya memperoleh akurasi sebesar 55.80 %. Sehingga Random Forest memiliki performa kinerja yang lebih unggul dalam perolehan akurasi yang dihasilkan dalam klasifikasi penyakit liver.

Abstract

Stocks are one of the many investments that are favored by all groups because they promise high returns. But in addition to promising high returns, stocks can also provide a high risk of loss, which makes ordinary people afraid to start investing in the stock market. To prevent losses in buying stocks is to choose stocks with good fundamentals. To support this, we need an analysis that can help make decisions in choosing the best stocks in the technology sector. The saw method analysis will be used in this study, where the saw method is able to select alternatives based on predetermined categories. This study will rank the best stocks based on company fundamentals, namely EPS, PER, PBV, ROE, DER and Dividend Yield. The results of this study are EDGE stocks as the best stocks in the technology sector with the highest value of 0.88. The purpose of this research is to help investors choose stocks before investing in technology companies.

Abstract

Contract employees are employees who work in contact with a certain time agreement. However, there are times when contact employees with good performance will change their status to permanent employees. To determine whether an employee is a permanent employee, an evaluation of whether the employee's performance is worthy of being appointed as a permanent employee is required. However, to carry out this evaluation, a variable is needed to make an assessment. In the performance evaluation it is not easy to determine the value of each variable. To assist an HRD in determining the appointment of a contact employee to become a permanent employee, a decision support system is needed to facilitate HRD work. The decision support system is made using the Tsukamoto fuzzy logic method because the Tsukamoto fuzzy has a tolerance for value data. The result of the research is that the employee can be appointed as a permanent employee with a value of 93.4. The purpose of this decision support system is to determine whether or not contract employees are eligible to become permanent employees based on alternative disciplines, ways of working and behavior.

Abstract

Schools are institutions for students to carry out early stages of education that are tailored to their level. Developments that continue to show their existence have a very rapid impact, for example school institutions. Currently, there are permanent schools (pondok/pesantren) or public schools (state/private) with their respective performances. However, the tendency of parents to choose the best school according to him without paying attention to the child's growth and development first. This often occurs after the transition from elementary school to junior high school (SMP). Especially for the Aceh area, where the majority of children are directly in hostel with the hope that the child can grow optimally without reviewing the advantages and disadvantages. The rapid development of technology in Indonesia has contributed a lot to the problems experienced by society with the birth of various kinds of intelligent systems. The development of an intelligent system based on this expert system can be a solution to the problems that arise for parents now, can determine the type of school children will go to in the future. by implementing a method that is able to make decisions by providing the best solution. The purpose of this study is to build an intelligent system that is able to provide decision support in determining the type of school. By providing services to parents in the form of a web service-based interface system. As well as understanding the type of child's ability before deciding to be in a boarding school or public school, especially at the junior high school level.

Abstract

This study discusses certainty factor analysis to diagnose diabetes mellitus (DM) which is implemented in a smart system that aims to make it easier for people to know the type of diabetes. A person's lifestyle is the main thing in maintaining health, but if you have an unhealthy lifestyle, it will cause disease. One of the many diseases caused by an unhealthy lifestyle is diabetes mellitus. The system built in this research will be implemented using the certainty factor (CF) method. Users can choose what symptoms are experienced on the system, where the symptoms are obtained from an expert. The output of this expert system is to diagnose the user as having type 2 diabetes mellitus. This research yielded 84% results. The purpose of this study is to help the community in diagnosing the type of diabetes experienced so that they can get the right treatment.

Abstract

The computer laboratory is one of the facilities that support the learning process, therefore, a professional laboratory management system is required to assist lecturers with computer laboratory upkeep. In the process of selecting laboratory assistants it takes quite a long time, is less efficient and cannot save the history of selection results automatically. So this research will create a decision support system using the simple additive weighting method to assist lecturers in selecting computer laboratory systems efficiently. The criteria used for selection were the GPA (Cumulative Achievement Index), Hardware Installation Tests, Software Installation Tests, LAN Installation Tests, Programming Tests, and Interviews. The final results of calculations using the simple additive weighting method will choose 2 alternatives with the highest scores to become computer laboratory assistants, namely alternative 4 (X4) with a value of 0.97 and alternative 2 with a value of 0.91 (X2). The decision support system will be built based on a website and the database system will use MySql.

Abstract

The use of capacitors in electrical systems is widely known for their function to improve power factor and voltage profile while minimizing power losses. It results from the reactive power correction provided by capacitors within the system. It is believed that proper placement and size of capacitors can enhance the electricity quality in power systems. Therefore, numerous methods have been developed regarding the allocation and sizing of capacitors. In this research, a meta-heuristic method, Particle Swarm Optimization (PSO) is applied to find the optimal allocation and sizing of capacitors in order to reduce losses. The method has also been improved by modifying the value of inertia weight to optimize the algorithm's performance in finding the solution. The method is tested on an IEEE 34 bus radial distribution system to observe its performance and effectiveness in identifying the solution. The power loss in the distribution system plays the most important role in the economic operation of the power system. It will be used as a fitness function for each particle in the algorithm. The obtained test results include the size of the capacitor and the optimal placement of the capacitor installation.
