Abstract

Kebutuhan energi nasional dan upaya untuk pemenuhan kebutuhan energi merupakan salah satu permasalahan saat ini. Salah satu yang masih menjadi problematika adalah kelangkaan gas yang terjadi pada tiap daerah berbeda, dimana tidak semua daerah mengalami kekurangan gas ada juga daerah yang kelebihan stok gas LPG. Oleh karena itu diperlukan aplikasi pemetaan lokasi distribusi gas elpiji berbasis android. Pada plikasi ini menerapkan algoritma ant colony untuk mencari rute tercepat lokasi pangkalan gas yang ada pada wilayah Kecamatan Medan. Langkah-langkah yang digunakan pada skema sistem ini yaitu: input lokasi, Algoritma Ant Colony, rute terpendek, menampilkan pemetaan lokasi distribusi. Algoritma Ant Colony merupakan algoritma yang paling sering digunakan dalam pemetaan lokasi distribusi. Penelitian ini berhasil membuat aplikasi pemetaan lokasi distribusi gas elpiji 3 kg dengan menggunakan Algoritma Ant Colony berbasis android pencarian jalur tercepat dengan menggunakan algoritma Ant Colony. Berdasarkan uji coba, semakin kecil jumlah kota yang diinputkan maka semakin cepat aplikasi menampilkan rute terpendek pada map.

Abstract

The capital market is one of the investment models that is currently growing so rapidly because there are more and more digital-based investment platforms that can be accessed using mobile smartphones. The amount of interest in investing makes many people who experience losses due to not understanding the investment risks. For this reason, it is necessary to have the ability to analyze technically based on historical data. The object of this research is LQ45 shares in three companies, Indofood Sukses Makmur Tbk (INDF), Unilever Indonesia Tbk (UNVR), and Aneka Tambang Tbk (ANTM). The method used in this research is the Triple Exponential Smoothing method which is a prediction method that utilizes the statistical analysis method. The variables used in this study are historical prices ranging from Open, High, Low, and Close prices. The stages used are the collection of 125 historical data, where the data is taken through the Google Finance financial database. Then the Triple Exponential Smoothing calculation process is carried out, the data is stored in the database and presented in the form of graphs and tables. By using the parameter values = 0.13 and = 0.87 in the end it produces a Mean margin error level of Open price -0.10681%, High price -1.1156%, Low price 1.4616%, and Close price -0.2504%. The results of the study mean the margin of error is between -0.1% to 1%. The application of Triple Exponential Smoothing can be applied to predict stock prices. This research is to help investors analyze stock price movements.

Abstract

This research discusses the comparison between two encryption algorithms, namely Advanced Encryption Standard (AES) and Fully Homomorphic Encryption (FHE), in the context of data security in Financial Technology (Fintech) applications. The main aim of this research is to analyze the speed and efficiency of the two algorithms to provide information and motivation to Fintech Application business actors to determine the right algorithm for securing data. The research results show that AES is faster and more efficient in terms of encryption and decryption compared to FHE. For encryption, the AES algorithm is 1,100 times faster than the FHE algorithm. For decryption, the AES algorithm is 581 times faster than the FHE algorithm. For arithmetic processing, AES is 132 times faster than FHE. CPU consumption for AES encryption is 35.93% lower CPU usage than FHE. In AES decryption 10.31% lower than FHE for CPU usage. In the arithmetic process AES is 9.33% lower in usage than FHE. For memory usage in the FHE encryption process, it has an advantage, namely 2.3 times lower than AES for memory usage. During decryption, AES memory usage is superior with memory consumption 54 times lower than FHE. For the arithmetic process, AES uses 4.3 times lower memory than FHE. Overall AES provides speed and low resource consumption, this makes AES very suitable for use in Fintech applications that require speed and efficiency. Even though FHE has advantages in memory usage during encryption alone, this is not enough because it takes a long time to carry out the encryption process. This research suggests that further research will attempt to make the FHE algorithm more efficient and faster in processing data, this is considering the potential of FHE which is able to process encrypted data
