Abstract

Some of Cilacap people live in coastal areas as fishermen who utilize the seafood to meet the needs of life. One of the fishermen supporters in the cruise is the information of Meteorological, Climatological, and Geophysical Agency (BMKG). This information is important for safety such as wind speed and wave height. For addressing the problem, research is conducted to determine the sailing schedule of fishermen using data mining method with the website based. The proposed method is using Support Vector Machine (SVM) classification algorithm. This research uses data from BMKG Cilacap from 2015 until 2017. Test data is part of data that is 30% randomly fetched from the overall data used. From model testing, get value with performance results from datasets that generate accuracy of 88%, 87% precision and 89% recall. This solution is followed by constructing the website in order to easy to access of sailing information. Therefore, the researcher created a website of fisherman sailing scheduling system based on SVM algorithm.

Abstract

There are many wonderful tourist attractions in Banyumas. Based on data which are obtained, its number are 25 locations while in this research focus on 11 objects as experiment. The purpose of this study was to determine the best path that connects the eleventh object using Genetic Algorithms especially TSP method. Based on the results are the best path length is 0.878 units of Cartesian with a population size is 25 and the probability of mutations is 0,005. The sequence paths are Purwokerto square, Andang pangrenan Parks, Baturraden, Dreamland Waterboom Ajibarang, Cipendok waterfall, educational tours of STMIK AMIKOM Purwokerto, Depo Bay Sokaraja, Goa Maria Kaliori, Museum of General Sudirman, BRI Museum, and Bale Kemambang

Abstract

An investment is a binding in a sum of money or other assets that is being made at this time with the hope of obtaining a profit in the future. The banking sector is a financial sector that can be used as an investment option. The most expected profit when someone makes an investment is the acquisition of dividends. Before making an investment, it is important for investors to carry out an analysis of dividend data distributed by bank companies so that investors can find out the picture of the profits they get. In this research, an exploratory analysis and visualization of dividend data were taken from the official dividend record platform which aims to provide bank recommendations that can be used as a place to invest and get maximum profits for investors. The sample was selected using purposive sampling method, 7 bank samples were obtained in this study. The data processing method is carried out using Python tools and visualization using Tableau Desktop. The results obtained from the analysis in this study are recommendations for banks as a place to invest, namely PT. Bank Asia Central Tbk., and PT. Bank Mandiri (Persero) Tbk.

Abstract

The primary objective of this research is to develop an image captioning and audio conversion system based on Convolutional Neural Networks (CNN) and Recurrent Neural Networks (RNN) with the integration of an Attention Mechanism, aimed at improving accessibility for visually impaired individuals. The research design follows a systematic approach involving data collection, preprocessing, model development, training, evaluation, and implementation. The methodology utilizes CNN for visual feature extraction, RNN for language modeling, and an Attention Mechanism to enhance contextual relevance in caption generation. Google Text-to-Speech (gTTS) is also integrated to convert generated captions into audio format. The main outcomes demonstrate that the model is capable of generating coherent and contextually relevant captions, as validated through qualitative assessment and quantitative measurement using the BLEU score. Experimental results show decreasing training and validation loss over 8 epochs without signs of overfitting, indicating stable model performance. The attention visualization confirms the model’s ability to focus on relevant image regions during caption generation. In conclusion, the proposed CNN-RNN architecture with Attention effectively generates descriptive captions and converts them into speech, showing strong potential for real-world accessibility applications.
