Abstract

Dunia manufaktur dan industri jasa memiliki permasalahan dibidang penjadwalan. Penjadwalan adalah proses pengambilan keputusan yang berkaitan tentang pengalokasian sejumlah resource dan tugas dalam waktu tertentu. Oleh karena itu, dibutuhkan suatu teknik untuk mendapatkan penjadwalan yang efektif dan efisien. Flow shop merupakan salah satu permasalahan penjadwalan yang dikategorikan dalam permasalahan NP-hard. Permutation akan menjadi kendala dalam lingkungan flow shop dimana mesin-mesin diatur secara seri dengan menyusun antrian job mengikuti aturan FIFO. Harmony search algorithm salah satu teknik metaheuristik yang terinspirasi dari permainan musik. Algoritma tersebut dapat digunakan untuk menyelesaikan permasalahan permutation flow shop untuk minimize makespan. Teknik penyelesaian dengan menggunakan algoritma tersebut menerapkan inisialisasi dengan variabel diskrit. Berdasarkan hasil pengujian yang telah dilakukan, harmony search algorithm efektif menghasilkan makespan yang lebih baik dari makespan yang terdapat pada benchmark data.

Abstract

One of the areas that can be a reference for the success and progress of a nation is the field of education. In the world of education, the examination has become one of the ways to measure learning achievement levels of students in the school. The examination that usually uses at school such as daily/weekly/monthly test, Midterm (UTS) and the Semester final exam (UAS). By using examination both students and teachers can evaluate each other about their teaching and learning activities. The examination model which used during this time is conventional methods model by using paper-based test. Traditional methods still have many shortcomings so that it takes another method for creating an efficient, effective, safe, accurate and fast test system. Another model which was already applied in the activities of the school students test is a method of Computer-Based Test (CBT Method). This way is proven to increase efficiency and effectiveness in the test. Unfortunately, this new approach is only applied to the activities of the national exam and have not been evenly distributed throughout the school. To use it in all the examination process such as daily/weekly/monthly test, Midterm (UTS) and the Semester final exam (UAS), the writer selected two school partners to implement CBT Exam in high school/Equal. Both schools are SMK Negeri 2 Binjai and MA "Mawaridussalam Deli Serdang. The target to be achieved is the creation of an alternative test method which can be used by the partner school that is more efficient, more effective, safer, more accurate and faster than old exam methods. The outcome which is to be accomplished is the creation of a system of computer-based test methods as an alternative method in the test of daily/weekly/monthly, UTS, and UAS on school partners by using PHP and My SQL.

Abstract

The result of the blood chemistry tests is usually presented in the form of a table written in abbreviations, numbers, and units. Unfortunately, the young doctors often require the time and experience for interpreting the blood chemistry tests into a textual representation which is easy to read and understand. Therefore, this research is aimed at developing a system (BTISys) that is able to generate the textual representation in the Indonesian language automatically based on the blood chemistry test. BTISys generates the representation using Natural Language Generation (NLG) approach based on the r-template method. The reliability of BTISys is measured by considering the naturalness of generated textual representation. The naturalness can be observed by three criteria, such as readability, clarity and general appropriateness. Based on the experiment, this research concluded that the reliability of BTISys is quite good in order to generate the textual representation automatically. This can be seen from the readability, clarity and general appropriateness which reach of 73%, 70%, and 60% respectively that implies the naturalness of generated textual representation.
