Abstract

PT. Wahana Lentera Raya didirikan pada tahun 2002 dan merupakan perusahaan yang bergerak di bidang Furniture. PT. Wahana Lentera Raya mengalami kesulitan dengan sering terjadinya kerusakan yang tidak terduga pada mesin, sehingga mengakibatkan mesin harus berhenti untuk berproduksi. Oleh karena itu PT. Wahana Lentera Raya meminta dilakukan penelitian untuk penjadwalan preventive maintenance. Dari 18 jenis mesin yang dimiliki oleh PT. Wahana Lentera Raya, yang dapat dilakukan penjadwalan maintenance-nya hanya 3 jenis mesin karena data yang dimiliki perusahaan masih kurang. Ketiga jenis mesin tersebut, yaitu BST, HPL dan BHC. Dari 3 jenis mesin ini dicari yang termasuk mesin kritis, dengan melihat tingkat utilitas mesin. Kemudian dari waktu antar kerusakan dicari distribusi data waktu antar kerusakannya agar dapat dilakukan perhitungan untuk menemukan nilai mean time of failure (MTTF), tingkat keandalan mesin, dan nilai ekspektasi kerusakan dari masing-masing mesin. Perhitungan nilai MTTF, tingkat keandalan mesin dan nilai ekspektasi kerusakan mesin ini nantinya digunakan dalam menentukan penjadwalan preventive maintenance. Penjadwalan preventive maintenance dilakukan dalam 3 skenario yang berbeda. Dari ketiga skenario penjadwalan maintenance ini, yang disarankan untuk perusahaan adalah skenario ketiga, karena effisiensi biaya yang cukup tinggi dan tingkat keandalan mesin yang di atas 80%.

Abstract

Along with the increase in population and the acceleration of economic expansion, there has been a concomitant increase in the urgent requirement for additional property that can serve as a venue for a wide variety of community activities. It is not uncommon for large cities, which are the epicenter of urbanization, such as the city of Surabaya, to experience a sharp increase in the demand for land. One of the regions that has excellent accessibility is the Sidoarjo Regency, which is comparable to the City of Surabaya in this regard. The goal of this research is to use Web-GIS to conduct an analysis of spatial data to identify the land functions that are most suitable for use in residential areas. The Analytic Hierarchy Process (AHP) and the Weighted Product Model (WPM) are two of the methodologies that are included in the spatial data modeling method that uses multi-criteria decision making (MCDM). The parameters of the characteristics that are used are derived from data such as the distance to the city center, the distance to the market, the distance to the hospital, the distance to public transportation, the slope, the type of soil, and the amount of rainfall. The results of the spatial data modeling categorize the suitability of new residential land into categories of land that is not suitable for residential use and land that is acceptable for residential use. A K value of 0.27 is the result of the comparison test that was run between the two MCDM approaches using Cohen's Kappa coefficients.

Abstract

The rapid evolution of digital technology has significantly transformed the financial services landscape, especially in the realm of mobile banking. BCA Mobile stands among the most popular apps for digital banking in Indonesia. Despite its widespread adoption, user reviews reflect diverse viewpoints and sentiments about the app. The objective of this research is to examine the user sentiments regarding the BCA Mobile app, based on reviews sourced from the Google Play Store and App Store. Two classification models, namely Support Vector Machine (SVM) and K-Nearest Neighbour (K-NN), are used in the analysis process. The collected review data undergoes several pre-processing stages and is labeled automatically using a Lexicon-Based technique. For feature weighting, the TF-IDF (Term Frequency-Inverse Document Frequency) approach is used.. Sentiment classification is then carried out using both K-NN and SVM, with performance evaluated through a matrix of confusion based on measurements like F1-score, recall, accuracy, and precision.  The findings show that the SVM algorithm outperforms K-NN in terms of performance, with an accuracy of 94%, while K-NN achieves an accuracy of 82%. This study offers valuable insights for BCA management in understanding user sentiment and enhancing service quality through the application of artificial intelligence

Abstract

The legal events that happened to Ferdy Sambo and the Supreme Court’s decision in the cassation triggered emotional reactions and various opinions among the public, especially on social media sites such as Xapps. Some comments reflect people’s concerns about fairness in the legal system. They doubted the integrity of legal institutions or believed that decisions were unfair or in line with vested interests. This research aims to analyze public perceptions of Supreme Court decisions. The research process includes data collection, preprocessing, labeling, weighting, classification using Support Vector Machine and Naïve Bayes, and performance evaluation using a confusion matrix. A dataset of 624 was taken from X apps using the Twitter scraping technique. The lexicon method is used for data labeling, dividing the data into positive, negative, and neutral classes. The analysis results show 46 tweets categorized as positive sentiment, 133 tweets categorized as negative sentiment, and 422 tweets categorized as neutral sentiment. Based on testing with a data ratio of 80:20, both SVM and NB methods show good performance. The SVM criteria showed an accuracy of 0.84, precision of 0.61, recall of 0.78, and f1-score of 0.66, while the NB criteria showed an accuracy of 0.73, precision of 0.37, recall of 0.57, and f1-score of 0.35.
