Abstract

Herbal chili plants are very beneficial from a health and economic perspective. In the process of cultivating herbal chili plants, there are still many problems that need to be faced, including unfavorable climatic conditions and less intensive cultivation processes. Based on this description, to overcome these problems, technological innovation is needed that can be implemented directly in the cultivation of herbal chili plants. This situation can be achieved by applying a drip irrigation system. This system makes it possible to control the water supply requirements of chili herbs efficiently. System stability can run optimally when combined with a method that can make a decision quickly. Fuzzy logic is used in research because it is able to provide appropriate decisions on temperature and soil moisture data in chili herbs. This research is expected to overcome the problem of water shortages in barren areas. And increase people's interest in the cultivation of herbal chili plants. This research is also an overview and framework for developing the agricultural sector in Madura in the technology field. The results of this study indicate that technology can be designed and integrated with the fuzzy logic control method, then the results of testing the tool also show a 99,98% success rate. This is shown by the results of testing in the morning, afternoon, and evening. The contribution of this study is the control of temperature and humidity which in other studies only focused on the soil, not on the temperature and humidity of the air around the herbal chili plants with a system that has been controlled using the fuzzy method.

Abstract

A number of businesses, such as TripAdvisor, Open Table, and Yelp, have successfully utilized aspect-based sentiment analysis in order to gain insights from reviews provided by customers and enhance the quality of their goods or services.  Businesses are able to swiftly discover any unfavorable sentiment or possible harm to their brand when they analyze client input across numerous aspects from social media, online reviews, and conversations with customer care representatives. This study aims to explain how aspect-based semantic analysis of market-collected user-generated data through performance comparisons of Doc2vec and TF-IDF vectorization. Both Doc2Vec and TF-IDF have their own distinctive qualities, which might vary according on the nature of the job, the dataset, and the volume of the available training data. For the objectives of this research, the data was obtained from several of fashion merchants that run their companies by means of the Shopee platform, which is a well-known online marketplace platform in Indonesia.  In this research, the accuracy and F1 Score achieved by Doc2Vec vectorization was superior to those achieved by TF-IDF vectorization. Our findings shows that Doc2Vec vectorization is better for classifying customer ratings because it can pull out the semantic meaning of words in a document. The findings also shows that the score of c and gamma parameter have significant impact to the score of Accuracy and F1 Score of the classifier.By precisely categorizing client sentiment, this study enables businesses to improve their services, respond to customers' problems, and increase their customer satisfaction.

ABSTRAKPada lembaga pendidikan khususnya Universitas banyak sekali menawarkan beasiswa kepada mahasiswa, terutama bagi mahasiswa yang sedang aktif kuliah, beasiswa yang ditawarkan diantaranya beasiswa PPA dan BBM. Untuk memilih penerima yang benar-benar layak mendapatkan beasiswa maka terdapat beberapa kriteria untuk proses seleksi yang akan dibobotkan menggunakan metode FAHP yaitu Indeks Prestasi Kumulatif, jumlah semester, penghasilan orang tua per bulan, jumlah tanggungan keluarga, daya listrik rumah, dan pekerjaan orang tua. Sedangkan untuk proses perangkingan data pendaftar beasiswa digunakan metode Oreste. Metode fuzzy AHP digunakan karena dapat menyederhanakan sontoto kompleksitas dan mengakomodir pendapat dan subjektifitas dari penilaian yang berbeda dan menerjemahkan pendapat Manusia yang memiliki ketidakpastian dalam melakukan pembobotan nilai(Chang, 1996). Sedangkan Oreste digunakan untuk kondisi dimana sekumpulan alternatif akan diurutkan berdasarkan kriteria sesuai dengan tingkat kepentingannya. Kemudian data Hasil seleksi penerima beasiswa yang dilakukan oleh sistem dibandingkan dengan data penerima asli/riil dengan cara mencari total data penerima yang sama pada data penerima beasiswa riil dan data penerima pada masing-masing fakultas yangterdapat di Universitas Trunojoyo Madura yaitu Fakultas Teknik, Fakultas Ekonomi, Fakultas Pertanian dan Fakultas Hukum. Secara keseluruhan dapat dikatakan bahwa hasil akurasi menggunakan sistem penyeleksian beasiswa menggunakan metode FAHP dan Oreste sebesar 74.9%.Kata Kunci : Sistem Pendukung Keputusan, Beasiswa, FAHP, Oreste. ABSTRACTIn educational institutions, especially the University of innumerable offer scholarships to students, especially for students who are active in college, scholarships offered them scholarships PPA and BBM. To select recipients who really deserve a scholarship then there are some criteria for the selection process will be weighted using FAHP method is GPA, number of semesters, parents income per month, number of dependents, power house, and the work of parents. As for the process of ranking the registrant data is also used method of Oreste. Fuzzy AHP method is used because it can simplify the complexity and subjectivity of opinion and accommodate different assessments and translate human opinion that has uncertainty in doing weighting value (Chang, 1996). While Oreste used to the conditions in which a set of alternatives will be sorted based on the criteria according to their importance. Then the data results grantee selection performed by the system as compared to the original recipient data / real by looking for the same total data receiver to the data of real scholarship recipient and recipient data on each faculty contained inTrunojoyo University the Faculty of Engineering, Faculty of Economics , Faculty of Agriculture and Faculty of Law. Overall it can be said that the accuracy of the results of the screening system using scholarships using FAHP method and Oreste at 74.9%.Keywords: Decision Support Systems, Scholarship, FAHP, Oreste.
