Analisis Sistem Informasi Pengolahan Data Nilai Mahasiswa Menggunakan PIECES pada Prodi Sistem Informasi STTH-Medan
In some parts of the education system, there are teaching and learning activities involving students and lecturers. And when doing some teaching and learning activities, some progress of student learning occurred which are grades obtained from the student’s examination. Presently, the student’s grades are processed conventionally which is done by each lecturer manually using pen, paper and a calculator. Thus, the Department will have difficulties managing the student’s grades given by the lecturer and the results will not be optimal either. If done manually, the lecturer must calculate the grade for each student one at a time. Moreover, students will have to wait for a long time finding out for their grades. It will take a long time and requires high precision for accurate calculations if the student’s grades processed manually. A PIECES Analysis, which is analyzing performance, information, economics, applications, and services, is used in analyzing student information system of the Information System Department STTH-Medan. The purpose of this study is to find out the data processing system and the data needed for developing STTH-Medan Information System. By using PIECES Analysis, it will be done in detail, and can be used for information systems.Keywords: Analysis, Information Systems, Grades, PIECES, UML
Optimasi Penjadwalan Menggunakan Metode Algoritma Genetika di Sekolah Menengah Kejuruan Annuqayah - Sumenep
The problem faced by the Annuqayah Vocational School curriculum is the same schedule and is taught by the same teacher. Such problems are quite complex problems because they relate to the number of teachers available. The lesson schedule is presented in the form of day and class hours tables. The subject can be seen that every day schedule divided into time slots. Each time slot has a list of subjects taught by the teacher in a particular room. To optimize the lesson schedule in Annuqayah Vocational School, Genetic Algorithm is used. This algorithm is a computational approach to the principle of natural selection, Charles Darwin's theory of evolution and the theory of Mendel's inheritance [1]. The optimization process in Genetic Algorithms includes individual generation, evaluation of fitness values, determination of probability values, Roulette Wheel selection, crossover, mutations, and new individual generation. Scheduling optimization using the Genetic Algorithm approach was declared successful because it was able to find the right combination of scheduling with optimal fitness values in 10 attempts, and no violations of the established rules from the curriculum were found so that it could assist in the preparation of subject schedules in Annuqayah Vocational High School.Keywords: curriculum, Vocational High School, scheduling, Genetic Algorithm, optimization.

Potensi Interoperabilitas Sistem Informasi Rumah Sakit Untuk Penerapan Standar Pertukaran Data HL7
The use and application of Information Technology (IT) at the hospital has been widely applied. However, the interoperability, an ability to exchange patient information between the information systems, is limited. During its development in the health field, the data exchange standard of the Health Level 7 (HL7) becomes one of the most widely used approaches in the world. It is likely to be true that in this globalization era, the patient information exchange can be conducted between hospitals from different countries. Therefore, this study proposes steps to analyze the potential of the interoperability hospital information system in applying the data exchange standard of HL7 which, according to the literature review found by the researcher, almost all of the research related to data exchange in the hospital employs web service and XML methods. The steps conducted in this research include: studying the mapping between the availability of the field in the proprietary information system and the element of the messages structure of HL7; identifying and analyzing each field and element so that the potential of the mapping result can be found and the data richness of the messages structure of HL7 can be calculated; and trying out step which is conducted in one of the hospitals in Yogyakarta. The problems found during the implementation is then analyzed to obtain the results. Keywords: Potential of Interoperability, HL7, Interoperability hospital information syste
