Judul: Sistem Pakar Diagnoisi ADHD (Attention-Deficit/Hyperactivity Disorder) pada Anak Usia Sekolah
Abstrak: Expert System Diagnosis of ADHD in School Aged Children (SPDAPA) is a computer system developed for diagnosing ADHD in children. This system is based on the signs of attitude and behavior of children at home. This study aims to find the facts and knowledge bases to diagnose ADHD (Attention-Deficit/Hyperactivity Disorder) and develop a web based Expert System Diagnosis of ADHD in school-age children. Certainty factor (CF) is the method used to develop this system. This method needs a value of belief and unbelief information from the parameters which are used as a variable count. Therefore process will find the certainty factor. This research methodology uses several stages: frame of mind, an approach system, system design, identification and system model. System development also uses waterfall method that includes the definition and purpose of analysis, software and system design, implementation and unit testing, integration and testing, operation and maintenance of the system. The results of this study show the parameters of ADHD divided into three categories: Inattention, Hyperactivity, and Impulsivity and 24 parameters found from experts acquisition process. Each parameter has a value of belief (MB) and disbelief (MD) with a range of values between 0 to 1, which is a variable to search the value of certainty factor (CF). Finally, the result of this system is certainty factor (CF) with range between -1 to 1.

Judul: The Development of information system services for Monitoring the Student Attendance and Test Grades which is usable at SMAN 3 Pekanbaru
Abstrak: SMAN 3 Pekanbaru is locating close to the market. Average rate of absenteeism (sick, license, absent and late) is 20 students (1.5%) of 936 students per day. The information services for monitoring the student attendance and test grades are a system that manages the student’s attendances and grades level. This system gives the reports not only from the student report and attendance book, but also managed and reported as an information transmission for the parents or school. The reports which are delivered to the parents have expected to help the schools to monitor the student study development at their home. This is an important matter because the advancement of the school cannot be detached from parent’s role and school environment. The information transmission or communication to the parents has done using Short Message Services from mobile devices. The Short Message Services have selected because it can run on every mobile device not has to be using a smartphone. The student attendance and grades reported not only sent directly by the system to the parents, but also could be requested by the parents to find out the attendance and grades information. The Development of system adopted System Development Life Cycle (SDLC) information system method. It includes the analysis, design, implementation and testing. The analysis uses for problem identification and system requirements. The design uses for system reflection. The implementation uses for design representation into a programming language so that produces an interface input and output system. The testing uses usability test for testing the system difficulties using USE Questionnaire. The usability testing gives the results that the systems is easy to use, benefit, fine accepted, and satisfy the parents and also give the easiness for the parents to monitor their child development in the school. The testing process of the system involves the parents as a respondent. Based on the usability testing results, the system is easy to use and help the parents to monitor the attendance and development of their child. The failure report from information sending process just gives the “sending error” report message without knowing the cause of that failure. It gives a chance for the future development to add some extra features such as a log error for impound all of the failure to give a clue for quick and precise problem solving.

Judul: Pembuatan Isoeugenol dari Eugenol Menggunakan Pemanasan Gelombang Mikro
Abstrak: Indonesia merupakan salah satu penghasil minyak cengkeh terbesar di dunia. Pasokan minyak cengkeh Indonesia ke pasar dunia mencapai 60% kebutuhan dunia. Pada tahun 2000, dari 2,080 ton minyak cengkeh yang dipasarkan, Indonesia memasok 1,317 ton (Deptan, 2005). Di negara-negara industri seperti Amerika Serikat, Perancis, Jerman, Italia, dan Inggris, minyak cengkeh digunakan sebagai bahan baku untuk membuat isolat eugenol dan derivatnya seperti isoeugenol dengan nilai tambah yang lebih tinggi. Harga eugenol sebesar Rp 75 000/kg, harga isoeugenol sebesar Rp 95 000/kg (Indesso, 2006) sedangkan harga minyak daun cengkeh Indonesia di pasar Internasional sekitar Rp 25 000/kg (Deptan, 2005). Isoeugenol merupakan senyawa yang banyak digunakan sebagai campuran dalam fragrances dan dalam produk-produk konsumsi harian seperti parfum, produk perawatan kulit, deodoran, sabun, shampo, deterjen serta sebagai bahan intermediet dalam produksi vanilin sintetik. Isoeugenol dihasilkan dari reaksi isomerisasi eugenol. Reaksi isomerisasi eugenol umumnya dilakukan dengan cara mereaksikan eugenol dalam larutan basa KOH atau NaOH pada suhu tinggi selama 5 – 7 jam (Cerveny et al., 1987). Lamanya waktu pemanasan konvensional ini diduga dapat dipersingkat dengan menggunakan pemanasan gelombang mikro. Aplikasi katalis basa yang membutuhkan jumlah yang berlebih dalam reaksi isomerisasi juga dapat digantikan dengan menggunakan katalis RhCl3.3H2O dalam jumlah yang lebih rendah (Chalk, 1977).
