Imbalanced data is a problem that often occurs when conducting research in the field of sentiment analysis. This problem occurs when the dataset being analyzed has more positive classes than negative classes or vice versa so that the terms majority and minority data appear. If the majority data is more dominant then the classification process tends to produce a classification into the majority …
One of the problems that occur in the city of Palembang in the environmental sector is the waste problem. There are many factors that cause waste problems to occur, one of which is due to population growth that continues to occur. The highest number of residents in 2021 was in Sukarami sub-district and Ilir Barat I sub-district so that it has an impact on the accumulation of waste. One solution…
Technology company Apple Inc develops and distributes an operating system called iOS. To find apps on iOS, users need to download apps from a service called the Appstore. Users can provide feedback to rate the application in the form of a rating. The better the rating, the more interested the user will be in the application and will download the application, so analysis is needed. The data used…
Cervical cancer is one of the malignant tumors in women that attacks the female reproductive organs. There are various methods of preventing cervical cancer, one of which is conducting a pap smear screening test which is done by taking or collecting cervical cell samples on the cervical uterine wall. This study discusses the comparison of classification methods on cervical cancer data using the…
Two basic techniques in cryptography are symmetric and asymmetric. Algorithm Caesar Cipher and Data Encryption Standard includes a symmetric algorithm, while the RSA algorithm includes an asymmetric algorithm. Algorithm hybrid which combines symmetric and asymmetric algorithms is formed to get the advantages of each algorithm. In the encryption and decryption process, high security is the basic…
The waste transportation route problem can be modeled as an Asymmetric Capacitated Vehicle Routing Problem (ACVRP) with the condition that the journey from place i to place j is not the same as the trip from place j to i. This study aims to optimize the garbage transport route in the ACVRP model in Ilir Timur 3 District using the Cheapest Insertion Heuristic (CIH) algorithm and the Simulated An…
Missing data is a problem where there are empty values or incomplete values in the data. The University of California Irvine (UCI) Machine Learning Repository dataset that records chronic kidney disease patient data is one of the datasets that has a data loss problem. Lost data handling can be done by two methods, namely deletion and imputation. One of the deletion algorithms is ReliefF, while …
Assignment problems are very common in a company. In the problem of assignment of officers will be placed on the most appropriate task. Assignment problems at PT. Bukit Asam, Tbk is located in TLS 1 TAL which is solved with the Generate and Test algorithm, the Hungarian method and a linear program modeling which is solved with LINGO 13.0 software. Operator placement on shift is one of the facto…
The research aims to determine the minimum distance and route for transporting waste in the Seberang Ulu 1 Palembang sub-district using the Greedy algorithm and the Simulated Annealing algorithm. The calculation is done by dividing the sub-district area into 4 working areas. The calculation results show that with the Greedy algorithm for each work area 1 to work area 4, the minimum distance and…
Vehicle Routing Problem (VRP) model can be implemented to determited the route for waste transportation which is solved using Ant Colony System (ACS) algorithm Cost Matrix. Pulau Semambu Village consists of 6 hamlets which have 12 Temporary Disposal Sites (TPS), 1 Final Disposal Site (TPA) and every 2 hamlets is formed into 1 Working Area (WK). The purpose of this study is to apply the ACS algo…
Designing the optimal route for waste transportation problems often uses the Vehicle Routing Problem (VRP) model. Genetic Algorithm (GA), which is included in the evolutionary algorithm, is one of the important discoveries in the optimization field. The mechanism of evolution in the development of living things is the reference in making GA and is based on the principles of genetics and natural…
A large amount of waste that occurs in Indonesia every year needs to be handled properly by the government, because it harms public health. One of the causes of a large number of waste piles is the population that continues to increase. The Plaju sub-district is one of the sub-districts in the city of Palembang which has a population increase of 0.06% per year. Garbage transportation is one way…
The problem of waste in Ilir Barat I district arises due to the large number of residents who lived there. The large population is the cause of the increasing volume of waste generated. Temporary waste disposal sites is one of the government's efforts in overcoming the waste problem. Therefore, this study aims to determine the location of the optimal temporary waste disposal sites in Ilir Barat…
This study discusses the determination of the location of the strategic covid-19 vaccine distribution in the Palembang city using the Set Covering Location Problem (SCLP) and p-Center Location Problem models and implementing the Greedy Reduction Algorithm. Based on calculations using the SCLP model and the p-Center Location Problem solved by the Greedy Reduction Algorithm, 14 locations were obt…

Classification is the process of classifying an object based on a certain model. This process is often used in various fields, such as health, environment, and data research. One application of classification in the health sector is to predict factors for heart disease. The dataset used to predict cardiovascular disease factors comes from the University of California Irvine (UCI). This dataset …
The problem of waste transportation routes with the Vehicle Routing Problem (VRP) model can be solved using exact or heuristic methods.

Pulau Semambu Village consists of 6 hamlets which have 12 Temporary Disposal Site…
Waste is a problem in people’s lives in urban or residential areas.The waste volume continues to increase along with the increased population and can decrease the quality of life of the people living. One of the plans to solve the waste problem is to provide a Temporary Disposal Site. This research discusses optimizing the location of Temporary Disposal Site in Sukarami District, which consis…
Credit-granting activities are included in business activities that have a high risk and affect the sustainability of the company as well as other financial institutions. In credit activities, non-performing loans often occur due to the failure to repay a number of loans in accordance with the agreed time.
