Abstract

Thermal is a very important thing in influencing the level of comfort of a room. The important factor for the thermal comfort of a room is influenced by several factors, namely the height of the building which also affects the wind speed that enters the room, air temperature in the room, relative humidity level, the activity of the occupants That can affect the speed of metabolism and clothing imposed by the occupants of the room. PMV (Predicted Mean Vote) which has a range of-3 to 3 which represents the cold codition until heat, can be determined the value of its condition by using the fuzzy logic. The fuzzy logic can decide on which conditions the room is taking into account the weight of its membership.

Abstract

ABSTRACT The library has the role of helping students to love reading books. The availability of books in various fields motivates students to come to visit the library, students can read or borrow library books. For this reason, library officers apply the rules for visiting the library. The Apriori algorithm is a part of data mining, namely the search for high frequency patterns such as activities that often appear simultaneously. The pattern that will be analyzed is the pattern of borrowing any books that are often borrowed so that librarians know the information of books that are often borrowed. With the application of a priori algorithms, book data is processed to produce a book borrowing pattern. After all the high frequency patterns were found, then association rules were found that met the minimum requirements for associative confidence A → B minimum confidence = 25%. Rules for sequential final association based on minimum support and minimum confidence, if borrowing an IPA, then borrowing MTK Support = 15%, Confidence = 42.8%.

Abstract

The library is a facility that provides information, sources of knowledge, and tools for learning. All this time,in the library of the One Roof One-Banyan One-Roof Junior Secondary School, in book lending transactions,they are only stored without any further data processing. In fact, the large amount of lending transaction datacan be used to find out the association rules between two or more books. To facilitate the process of borrowingbooks in a library, especially in terms of finding books to be borrowed, Apriori algorithm with the associationrules (association rules) so that information can be extracted about what books are often borrowed and knowthe pattern of the relationship between books that have been borrowed together so that later can be used tomake the preparation of books in accordance with the existing book lending patterns so can facilitate libraryvisitors in the process of finding books

Abstract

ABSTRACT Fertilizer and Pesticide sales prediction is a process for finding, assessing, and predicting fertilizer and pesticide sales for the future based on sales results in the past few months. The increasing demand from customers for Fertilizers and Pesticides means UD. Mr Zen Agro, which operates in supplying and selling necessities, needs to record sales transactions so that stock shortages and excess stock of goods do not occur. Using data mining techniques and applying the C4.5 Algorithm can help UD. Mr Zen Agro predicts sales of Fertilizers and Pesticides as a reference or guideline in making decision trees, which are able to predict sales data with a high level of accuracy by calculating the entropy value, information gain, split info, and gain ratio until the matter can no longer be calculated or is zero. An application system exists to predict sales of fertilizers and pesticides, which applies the C4.5 algorithm to UD. Mr Zen Agro, it can be seen how big the sales prediction results obtained can be implemented in a decision tree where from the decision tree, it can be seen which fertilizers and pesticides are in demand and which are not for sale. This system was built using the PHP programming language and MySQL as the database. Keywords: Data Mining, Sales Prediction, Fertilizer and Pesticide, Algorithm C4.5.   Keywords: Data Mining, Sales Prediction, Fertilizer and Pesticide, Algorithm C4.5.

Abstract

Teachers are the most influential component in creating quality educational processes and outcomes. Therefore, improvement efforts are made to improve the quality of education. Schools will not make a significant contribution without the support of professional and qualified teachers. Teachers are really required to have high performance. To improve the quality of teacher performance, the 064022 State Elementary School conducts teacher performance appraisals every 3 months but the mechanism is less effective due to lack of transparency. Research on teacher performance appraisal using the system is applied for efficiency and transparency. The system was developed using the Simple Additive Weighting method. The Simple Additive Weighting method is part of the Decision Support System (DSS) used to help determine decisions based on alternative data and criteria data.

Abstract

Berkembangnya jaringan komunikasi membuat pertukaran informasi semakin sering terjadi, baik dalam bentuk teks, audio, dan video. Semakin banyaknya pesan yang yang ingin dikirimkan maka keamanan dan kerahasiaan dari pesan tersebut semakin sulit dijaga. Keamanan dan kerahasiaan adalah aspek yang penting pada proses pertukaran informasi atau pesan. Untuk melindungi kerahasiaan pesan bisa menggunakan teknik kriptografi. Kriptografi adalah ilmu yang mempelajari teknik – teknik matematika yang berhubungan dengan aspek keamanan seperti kerahasiaan, integritas data, serta otentikasi. Sedangkan Steganografi adalah salah satu teknik yang dilakukan dalam mengamankan pesan yaitu dengan cara menyembunyikan pesan ke sebuah media digital. Pada penelitian ini dilakukan analisis untuk mengimplementasikan keamanan file txt dan rtf dengan kombinasi algoritma kriptografi One Time Pad dengan steganografi least significant bit (LSB). Pada tahap kriptografi pesan yang telah berhasil diinput akan dienkripsi dengan kunci yang telah diberikan kemudian dilanjutkan dengan proses penyisipan pesan di tahap steganografi.. Pesan yang dapat dibaca oleh sistem adalah pesan berformat .txt dan .rtf. Pada Algoritma LSB penyisipan dilakukan dengan menggantikan bit terakhir citra dengan bit pesan yang akan disisipkan. Pada tahap enkripsi dan penyisipan akan dihasilkan stego image, stego image merupakan citra yang sudah disisip oleh pesan. Kemudian pada tahap ekstraksi dan dekripsi yang dihasilkan adalah plaintext, plaintext merupakan pesan yang belum diberikan kunci apapun.
