Abstract

This research started from the need for XYZ company to be able to present reports or data quickly when needed. There are so many trouble tickets per month, so PT XYZ needs information from historical data that can be seen from various dimensions, especially regarding trends that occur in trouble tickets. With this research, it is possible to develop a data warehouse originating from the operational database from PT XYZ, perform data warehouse analysis with Tableau software to find out trends in trouble ticket activity transactions. The data warehouse development method is to use the nine step design methodology development method using pentaho software. Based on the obtained trends, an information analysis of the number of Trouble tickets was carried out based on two dimensions, namely location and time, and it was found that in the 2nd and 3rd week of each month they had the most trouble tickets. This is due to the influence of the weather in these locations. Then an evaluation was carried out through a questionnaire using the Technology Acceptance Model (TAM), and the average rating from users was 3.83-4.22 which stated that this research could provide benefits and be accepted by PT XYZ.

Abstract

Hidroponik adalah suatu metode bercocok tanam yang tidak menggunakan tanah sebagai tempat tumbuh tanamannya, melainkan menggunakan air yang mengandung nutrisi yang diperlukan oleh tanaman. Salah satu tanaman yang dapat di budidayakan mengguakan teknik hidroponik yaitu tanaman bayam. Kekurangan dari penerapan teknik ini adalah membutuhkan ketelitian, ketelatenan, dan pembinaan secara terus menerus. Untuk mengatasi masalah tersebut maka dapat memanfaatkan kemajuan teknologi yang sudah berkembang. Saat ini banyak sistem yang mampu mengolah dan mengerjakan pekerjaan manusia yang dilakukan secara manual dapat menjadi lebih mudah, cepat, dan akurat baik dari segi waktu dan tenaga. Maka dibangunlah sistem budidaya tanaman bayam pada hidroponik Deep Flow Technique berbasis Internet of Things. Penelitian ini menggunakan metode pengembangan sistem prototype yang dirancang menggunakan beberapa komponen yaitu arduino uno sebagai pusat kontrol sistem, sensor pH sebagai input pH nutrisi, sensor TDS sebagai input kepekatan nutrisi, dan sensor ultrasonik sebagai input ketinggian udara. Hasil dari penelitian ini yaitu sistem yang dapat memantau, otomatisasi dan kontrol pemberian nutrisi pada tanaman hidroponik. Informasi mengenai tanaman akan dikirimkan melaui website, sehingga dapat mempermudah dalam melakukan pengecekan kondisi tanaman.

Abstract

Perkembagan teknologi akan terus berkembang sangat cepat dalam kemajuan di segala bidang dan dapat memudahkan pekerjaan manusia, salah satunya yaitu dalam sektor bidang pertanian. Salah satu dari kemajuan teknologi tersebut yaitu dalam sistem kontrol dan otomatisasi. Cuaca di Indonesia seringkali tidak menentu, sehingga menyebabkan menyebabkan terjadinya gagal panen, Hal ini membuat petani menggunakan beberapa cara untuk membuat tanaman mereka dapat tetap bertahan meskipun cuaca seringkali berubah, salah satunya adalah dengan menggunakan greenhouse. Masalah yang ada di greenhouse pada tanaman tomat apel yaitu belum adanya alat untuk monitoing ph tanah, suhu dan kelembapan secara realtime, selain dari itu, penyiraman tanaman masih manual sehingga membutuhkan waktu yang cukup lama dalam proses penyiraman serta kurang meratanya pemberian nutrisi sehingga tumbuhan tomat tidak tumbuh dengan baik, selain dari itu petani sedikit kesusahan dalam mengecek tandon air penyiraman karena masih diisi secara manual. Untuk memudahkan para petani dalam menyiram tanaman dan pemberian pupuk dan nutrisi. Perancangan monitoring ini menggunakan metode prototype dan logika fuzzy sugeno. Dari hasil pengujian sistem, maka di dapatkan error dari sensor kelembapan tanah (Soil Moisture) sebesar 0,03% dengan selish 2,4, error dari sensor ultrasonic sebesar 0,08% dengan selisih 9,6, dan error dari Sensor DHT 11 (Sesnor suhu) sebesar 0,036% dengan selish 0,74. Rata-rata error yang dihasilkan dari perbandingan lamanya penyiraman antara matlab dan jam digital adalah 0,844%.

In this regard, sentiment analysis was carried out through social media twitter to measure the accuracy value using the SVM (support vector machine) algorithm. Sentiment analysis by crawling twitter data as many as 1000 tweet data in Indonesian using the RapidMiner tool. And this classification with SVM (Support Vector Machine) algorithm gets an accuracy of 92% by testing at 80:20 proportion, which is 80% training data and 20% testing data. Of the 998 data that have been preprocessed, 625 data on the positive class and 374 data on the negative class have been obtained.

Abstract

Hoax news or fake news has become a significant problem in today's digital era, the news in question is information on job vacancies on social media, one of which is Twitter, which is widely discussed by job seekers. The spread of hoax news related to job vacancies can cause harm to job seekers who rely on this information to find work. Therefore, sentiment analysis of hoax job vacancies is important to help users distinguish between valid and hoax information. This study aims to analyze sentiment towards hoax news related to job vacancies on Twitter. The method used is the Naive Bayes method, which is a classification method commonly used in sentiment analysis. Hoax news dataset collected from job vacancy information will be processed and features that are relevant to job vacancies will be identified. Furthermore, the Naive Bayes sentiment analysis model will be developed to classify hoax news sentiment as positive or negative. The results of sentiment analysis will help users identify and avoid hoax news related to job vacancies. In addition, the results of sentiment analysis also improve the quality of the content displayed and strengthen user confidence in the information provided. It is hoped that this research will contribute to overcoming the problem of hoax news on Twitter, improve the quality of available information, and assist job seekers in making better decisions in finding work.

Abstract

This study aims to design and develop a web-based employee promotion evaluation system at PT Timbul Mandiri Agung using the Weighted Scoring method. The system was developed to improve efficiency, accuracy, and transparency in the evaluation process, which was previously conducted manually. The Weighted Scoring method enables objective decision-making by assigning weights to evaluation criteria such as performance, work experience, skills, attitude, discipline, and attendance. The study adopted the Waterfall model for system development, including requirements analysis, system design, implementation, testing, and evaluation. The results indicate that the proposed system enhances evaluation accuracy, accelerates decision-making processes, and increases employee trust in the company’s evaluation system.
