Analysis of hotel review sentiment is very helpful to be used as a benchmark or reference for making hotel business decisions today. However, all the review information obtained must be processed first by using an algorithm. The purpose of this study is to compare the Classification Algorithm of Machine Learning to obtain information that has a better level of accuracy in the analysis of hotel reviews. The algorithm that will be used is k-NN (k-Nearest Neighbor) and NB (Naive Bayes). After doing the calculation, the following accuracy level is obtained: k-NN of 60,50% with an AUC value of 0.632 and NB of 85,25% with an AUC value of 0.658. These results can be determined by the right algorithm to assist in making accurate decisions by business people in the analysis of hotel reviews using the NB Algorithm.

Abstract-As with Japanese animated films or can also be called an anime film which is now starting to be popular with all circles regardless of age, status and profession.

One way to increase the appeal of anime films is to use the genre data that is often watched by anime movie lovers. With these data we foam analyze what types of genres are the most watched, as well as the tendency to choose alternative genre types that are liked by anime movie lovers. So with these data the creator can determine the strategy for the type of genre that will be created next. a priori algorithm is good for use for itemset formation, pattern searching and so on. Therefore in this study the a priori algorithm was used to determine the pattern of selection of genre types in Japanese Anime Films.

Plate Wire mengalami kerusakan ketika akan dilakukan proses spiral setelah di proses rolling dari solid wire. Kerusakan yang terjadi patah pada saat awal proses spiral. Dengan pengamatan visual kerusakan Plate Wire, harus dilakukan pengujian - pengujian untuk memastikan penyebab kerusakan tersebut meliputi pengujian komposisi material, uji kekerasan, dan uji metalografi dan pengamatan struktur mikro. Analisa hasil pengujian di bandingkan dengan literatur, standart material internasional, dan faktor - faktor pendukung lainnya diharapkan mampu menjadi referensi pengambilan keputusan yang tepat tentang penyebab utama kerusakan. Hasil uji komposisi kima yang paling berpengaruh unsur karbon (C) pada (0,648 % C) tidak sesuai dengan standar JIS G4051 2007 (0.42 – 0,48%C), dan rata - rata nilai kekerasan sebesar 488,666 HV tidak sesuai dengan standar JIS G4051 2007 (160 – 230) HV. Kesimpulan penyebab utama kerusakan digunakan untuk pengembangan kwalitas Plate Wire serta upaya improvement sifat material untuk memperpanjang umur material (life time) meliputi heat treatment, komposisi material, manufaktur, serta penerapan prosedur kerja yang tepat.
