Abstract

Agriculture is one of the main sectors in Karo Regency, North Sumatra. One of the commodities produced by farmers in Karo Regency is carrot. The inability of farmers to control soil moisture may cause crop damage to a lack of productivity. This research aims to create a monitoring & control system that is integrated with the website to make it easier for farmers to prevent problems that occur. The method used in the research is the design, installation, monitoring, and deactivation. The results obtained from this research are that farmers can now monitor the field conditions in real-time using a web-based monitoring & control system.

Abstract

ABSTRAK- To prevent stroke, we need a way to predict whether someone has had a stroke through medical parameters. With the influence of technology in the medical world, stroke can be predicted using the Data Science method, which starts with Data Acquisition, Data Cleaning, Exploratory Data Analysis, Preprocessing, and the last stage is Model Building. Based on the model that has been made, it is concluded that the algorithm with the best performance, in this case, is XGBoost with a precision value of 0.9, a recall value of 0.95, an f1 value of 0.92, and a ROC-AUC value of 0.978 after receiving five folds of cross-validation. With these results, the model created can be used to make predictions in real-time. Kata kunci : Machine Learning, Logistic Regression, Random Forest, XGBoost, Stroke

Abstract

In order to revive the airline industry, which is being hit by the current recession, it is essential to restore passenger confidence in airlines by improving the services provided by airlines. With the influence of technology in all industrial fields, airlines can now use Machine Learning to find the essential points that can make passengers feel satisfied with airline services and classify passenger satisfaction. This study presents the making of Machine Learning models starting from Data Acquisition, Data Cleaning, Exploratory Data Analysis, Preprocessing, and Model Building. It is concluded that Random Forest is the best algorithm used in this case study, with an F1 accuracy score of 89.4, ROC-AUC score of 0.90, and a shorter modeling period than other algorithms used in this study.

Abstract

Since the COVID-19 pandemic, many activities are now carried out in a Work From Home (WFH) manner. According to data from the Central Statistics Agency (BPS) of East Java, in 2021, large and medium-sized enterprises (UMB) who choose to work WFH partially are 32.37%, and overall WFH is 2.24% (BPS East Java, 2021 ). With this percentage of 32.37%, many people need a work device (in this case, a laptop) that can boost their productivity during WFH. WFH players must have laptops with specifications that match their needs to encourage productivity. To prevent buying laptops at overpriced prices, a way to predict laptop prices is needed based on the specified specifications. This study presents a Machine Learning model from data acquisition (Data Acquisition), Data Cleaning, and Feature Engineering for the Pre-Processing, Exploratory Data Analysis stages to modeling based on regression algorithms. After the model is made, the highest accuracy result is 92.77%, namely the XGBoost algorithm. With this high accuracy value, the model created can predict laptop prices with a minimum accuracy above 80%.

Abstract

Apples are an essential commodity produced in Batu City, Malang. In 2017, Batu City, Malang, produced 19.1 tons of apples, while in 2018, Batu City, Malang, produced 15.9 tons of apples. It can be concluded that the decline in the number of apple harvests in Batu City, Malang. With the influence of technology in agriculture, the influence of technology can be used to detect diseases on leaves to overcome the decrease in the number of harvests. With the Image Augmentation method used in this study, the existing dataset can have 6x more features. So that the healthy category, which previously had 516 image features, now has 3096 image features, the scab category, which previously had 592 image features, now has 3552 image features and the rust category, which previously had 622 image features, now has 3732 image features. With a dataset with 3000 image features, the model to be made can have a higher accuracy value. The model can be said to be sturdy/sturdy/good, or the model to be made can carry out the classification process with a good level of accuracy.

Abstract

Bahasa merupakan aspek fundamental yang tidak hanya berfungsi sebagai alat komunikasi, tetapi juga sebagai sarana pembentukan, penguatan, dan pelestarian identitas budaya suatu masyarakat. Melalui bahasa, nilai-nilai, norma, sistem kepercayaan, serta tradisi ditransmisikan dari generasi ke generasi sehingga memungkinkan terjadinya kesinambungan budaya. Bahasa juga berperan sebagai simbol identitas yang mempertegas perbedaan dan keunikan suatu kelompok sosial dari kelompok lain, baik dalam lingkup lokal, nasional, maupun global. Identitas budaya yang dibangun melalui bahasa tidak bersifat statis, melainkan dinamis, karena terus beradaptasi dengan perkembangan zaman, teknologi, serta interaksi antarbudaya. Dalam konteks globalisasi, bahasa menghadapi tantangan besar berupa dominasi bahasa internasional yang berpotensi menggeser eksistensi bahasa daerah dan melemahkan identitas budaya lokal. Namun demikian, bahasa juga dapat menjadi instrumen perlawanan kultural melalui revitalisasi bahasa daerah, penguatan literasi, serta kebijakan bahasa yang mendukung keragaman linguistik. Dengan demikian, bahasa memiliki peran strategis dalam menjaga keseimbangan antara pelestarian kearifan lokal dan keterbukaan terhadap pengaruh global. Kesadaran akan peran bahasa dalam membentuk identitas budaya sangat penting untuk memperkuat jati diri bangsa, mendorong dialog antarbudaya, serta menciptakan harmoni dalam kehidupan masyarakat yang semakin plural dan multikultural.
