Abstract

Earthquakes are a type of natural disaster that currently cannot be predicted. Predicting the value of earthquake magnitude for related parties such as government and National Disaster Management Authority is very important. Furthermore, the results of earthquake predictions by several parties are used as indicators in post-earthquake response in minimizing the risks that will occur. Several studies have applied machine learning methods to predict earthquakes such as deep neural networks and parallel Support Vector Regression. In this article, we propose a data mining method using the Support Vector Machine (SVM) algorithm accompanied by the optimization of the windowing parameter value in the model that is applied to predict the value of the earthquake magnitude. Based on its advantages, the SVM model was chosen because it has been applicable in time series data processing. In the experimental stage process, parameter settings are first carried out, namely setting the kernel type, sampling type, and number of windowing to optimize the level of accuracy of the resulting model. The results showed that the best model with the smallest Root Mean Square Error (RMSE) was 0.712.

Abstract

Excessive consumption of gluten can cause disturbances in the digestive system and can increase intestinal permeability. Breadfruit flour is an alternative in making wet noodles other than wheat flour which is low in gluten. Breadfruit flour which is processed into wet noodles has low adhesion and protein content.Canna flour and carrageenan were used to improve adhesion and squid ink and eggs were used to increase the protein content of breadfruit noodles. This  study aimed to  determine the effect of adding carrageenan with different concentrations on breadfruit noodles. The ratio of addition of carrageenan in this research was 0%,1%, 3%, 4%, and 5%. Carrageenan in breadfruit noodles causes the noodles break more easily than noodles without the addition of carrageenan. The use of eggs and squid ink on breadfruit noodles increased the protein content of noodles by ± 1.1%.The results of the proximate analysis of breadfruit noodles as a whole still do not reach the SNI standard for wet noodles.

Abstract

Breadfruit is one of the alternative sources of new carbohydrates in the form of wet noodles. Breadfruit flour is a gluten-free food product, which is good for digestion and also for children with autism. Carrageenan is added to the manufacture of noodles as a substitute for gluten in the dough. To add color and taste, squid ink is added as a natural dye for breadfruit noodles. This study aims to determine consumer acceptance of breadfruit flour-based wet noodles with the addition of carrageenan as a thickener and squid ink as a dye. This study used a completely randomized design (CRD) with five treatments, namely with the addition of carrageenan 1%, 3%, 4%, 5% and without the addition of carrageenan (0%). Based on the results of the study, it was found that the water content of breadfruit flour was 2.86%, ash content was o, 2% and protein content was 6.35%. Based on the sensory test, it was found that the P value > 0.05 on all parameters, namely color, taste, aroma and texture, which means that the difference in carrageenan concentrations is not significantly different. The most preferred color by panelists on noodles with the addition of 7% carrageenan. The most preferred taste in breadfruit noodles without the addition of carrageenan and 5%. The most preferred aroma in noodles with the addition of 5% carrageenan. The most preferred texture in noodles with the addition of 1% carrageenan.

Abstract

The rapid development of information technology encourages innovation in various fields, including the field of disaster geographic information services. Lack of information on ambulance service providers is often the cause of delays in handling victims of natural disasters. Besides, the absence of information regarding the nearest route for ambulances to emergency service providers such as health centers and hospitals adds to the length of time for handling victims of natural disasters, resulting in increasingly severe victim losses, including life. This study aims to create a geographic information system that can be used to provide information on the location of the nearest ambulance service provider and emergency unit service. The system development research method uses the extreme programming method by implementing the Djikstra algorithm to determine the shortest route. This system testing process consists of testing the Djikstra algorithm and testing functionality using a usability scale. Djikstra's algorithm testing is done by comparing the results of calculating the shortest route for two location points with the results obtained when using the Google Maps application. The results of this test indicate that the system can display shorter routes than the routes generated by the Google Maps application. On the other hand, testing system functionality using the usability scale method to see system acceptance by users shows that the application can be used properly with a score obtained that is 77.

Abstract

Improving services as an effort to provide the convenience of tourist destinations, especially on the south coast of Java, is a demand placed on tourism managers, which in the long run will yield positive impacts. The assessment is conducted to determine whether the tourism destination give positive impressions to the tourists. The application of machine learning-based text mining technology, especially a sentiment review, is one of the solutions proposed to overcome this problem, therefore predictions of coastal tourism potential can be known beforehand. This research proposed a coastal sentiment review model using the library support vector machine (LibSVM) method. The process proposed a model optimization based on feature weights using the particle swarm optimization (PSO) algorithm as a model optimization to increase the accuracy level. Efforts to improve the accuracy of the proposed model are the main contribution of this research. The results of research and experiments on the proposed model produced the best model named LibSVM_IG+PSO using the information gain (IG). On the other hand, PSO-based LibSVM method generated an accuracy level of 88.97%. The model proposed in this research is expected to serve as a decision support for tourists, government, and tourism managers in assessing sentiment towards the coastal maritime tourism.

Abstract

Plagiarism is an act of imitating, quoting and even copying or acknowledging the work of others as one’s own work. A final project is one of the mandatory requirements for students to complete learning at college. It must be written by the students based on their own ideas. However, there is much plagiarism because it is easy to carry out just by simply copying the text of other people’s ideas and then pasting it into a worksheet and admitting that the ideas are theirs. In addition, replacing some words in other people’s sentences with their own language style without properly acknowledging the original source of the quotation is also an act of plagiarism. A manual check for the final project also becomes an issue for the final project coordinator, i.e., it needs high accuracy and a relatively long time to check the plagiarism in the final project document. Therefore, implementing plagiarism detection mechanisms is necessary to mitigate the escalation of plagiarism occurrences. In response to those matters, this study aims to design a system capable of identifying textual similarities by focusing on sentences containing synonymous words. One of the used algorithms is synonym recognition, which detects words that possess synonymous meanings by comparing each term with the entries in a dictionary. The synonym recognition is combined with the winnowing method, functioning as a fingerprint-based text weighting. After the weight of each document is obtained, the similarity level between documents is calculated with the cosine similarity algorithm. The inclusion of synonym recognition in conjunction with the winnowing weighting method resulted in a notable gain of 3.11% in the average similarity scores for title and abstract detection, compared to the absence of synonym recognition. The results show that the used algorithms are accurate with accuracy testing and root mean squared error (RMSE).

Abstract

An assessment of a place will provide an overview for other people whether the place is feasible to be visited or not. Assessment of coastal places will provide a separate assessment for potential visitors in considering visitation. This article proposes a model using the neural network (NN) and naïve Bayes (NB) methods to classify sentiment toward coastal assessments. The proposed NN and NB models are optimized using information gain (IG) and feature weights, namely particle swarm optimization (PSO) and genetic algorithm (GA) which are carried out to increase the level of classification accuracy. Based on the experimental results, the best level of accuracy for the classification of coastal assessments is 87.11% and is named the NB IG+PSO model. The best model obtained is a model that can be used as a decision support for potential beach visitors in deciding to visit the place.
