PENINGKATAN MINAT DAN PRESTASI SISWA KELAS XI MATA PELAJARAN SISTEM REM MELALUI MEDIA VISUAL GAMBAR DI SMK PERINDUSTRIAN YOGYAKARTA TAHUN PELAJARAN

Penelitian ini bertujuan untuk meningkatkan minat belajar siswa mata pelajaran Sistem Rem dengan menggunakan media visual gambar dan meningkatkan prestasi belajar siswa pada pembelajaran mata pelajaran sistem rem yang diajar dengan menggunakan media visual gambar. Penelitian ini merupakan penelitian tindakan kelas (Classrom Action Research) dilaksanakan di SMK Perindustrian Yogyakarta. Setiap siklus dilakukan 4 kali pertemuan di mulai tahapan perencanaan, pelaksanaan tindakan, observasi dan refleksi. Analisis data dilakukan dengan perbandingan antara hasil observasi pada siklus I, siklus II, siklus III dengan teknik deskriptif kualitatif yang diterangkan dalam nilai rata-rata hasil belajar dan persentase aktivitas belajar siswa. Hasil penelitian menunjukkan penerapan pendekatan pembelajaran dengan menggunakan media visual gambar pada mata pelajaran sistem rem dengan strategi pembelajaran dengan menggunakan media visual gambar adalah dengan memberikan presentasi kelas dengan menggunakan gambar yang berupa poster, flash, walchart dan menggunakan power point. Besar peningkatan minat siswa dapat diketahui dari lembar observasi minat siswa dan prestasi belajar siswa naik dari siklusnya. Ini bisa dilihat dari meningkatnya nilai/skor rata-rata jumlah semua aspek perasaan senang, perhatian, kemauan untuk belajar, aktivitas keterlibatan siswa dalam pembelajaran, aktivitas siswa dalam menerima dan memahami pembelajaran dari siklus I dengan nilai 2,79 dengan kategori cukup baik. Naik pada siklus II dengan nilai 3,17 dengan kategori cukup baik. Selanjutnya Pada siklus III dengan nilai 3,58 dengan kategori cukup baik. Sedangkan dilihat dari perolehan prestasi siswa mengalami kenaikan ditandai dengan peningkatan nilai rata-rata kelas dari siklus I dengan nilai 63,79 dengan kategori kurang baik, naik pada siklus II dengan nilai 72,97 dengan kategori sedang, naik pada siklus III dengan nilai 74,14 dengan kategori sedang. Jika dipersentasikan tingkat kelulusan mencapai 82,35% hal ini berarti baik karena pencapaian kompetensi kelas mencapai 70%

Planets around active stars

We present the results of radial velocity measurements of two samples of active stars. The first sample contains field G and K giants across the Red Giant Branch, whereas the second sample consists of nearby young stars (d < 150 pc) with ages between 10 - 300 Myrs. The radial velocity monitoring program has been carried out with FEROS at 1.52 m ESO telescope (1999 - 2002) and continued since 2003 at 2.2 m MPG/ESO telescope. We observed stellar radial velocity variations which originate either from the stellar activity or the presence of stellar/substellar companions. By means of a bisector technique we are able to distinguish the sources of the radial velocity variation. Among them we found few candidates of planetary companions, both of young stars and G-K giants sample.Comment: 4 pages, 5 figures, to appear in the Proceedings of the ESO Workshop "Precision Spectroscopy in Astrophysics", eds.

Multi User Decision Support System For Teachers Sertification With HTTPS

Education quality is a key condition to realize the life of a developed nation, modern dan Prosperous. (Fasli Jalal 2008) Teacher quality greatly affect the effectiveness of learning (Suherman, 2007, Rink, 2002). Teacher certification program is a way to improve the quality of teachers so that the quality of education will be increased dan in turn affect students' achievement (Siedentop & Tannehill, 2000). The purpose of this paper is to discuss the design of decision support systems passing teacher certification so as to facilitate the certification team dan assessors in the decision making sertikasi teacher graduation. In this paper we use a qualitative method based on system development life cycle (SDLC), including planning, analysis, design, dan implementation. Design of decision support systems passing teacher certification can provide information about passing the certification of teachers, as information analysis dan control in teacher certification assessment conducted by the assessor dan teacher certification of graduation information.

APPLICATION OF REMOTE AND MONITORING BASED JAVA REMOTE METHOD INVOCATION

This research aims to develop application software of Remote and Monitoring based on Java Remote Method Invocation (RMI). This application software can be used as remote control and monitoring on a connected computer network that is not limited to the operating system used. This study uses an object-oriented software development and combined with the waterfall software model process which through 4 stages. The first stage, analysis requirement, observation of the application of existing remote system, and the study of literature. Second stage, the design of the system include use case diagrams that illustrate the actors activities of the application and sequence diagrams describe the sequence of execution of applications. Third stages, coding, coding implementation of the design sequence diagrams and test units or more often called white-box testing. Fourth stages, integrated testing includes the black-box testing, alpha testing that will be used to determine the performance of the application, and beta testing to users of the Focus Group Discussion Digital Networks and Multimedia Puskom UNY. Based on the testing results of software applications Remote and Monitoring based on Java Remote Method Invocation (RMI) indicates that: 1) Application of Remote and Monitoring based Java Remote Method Invocation has been successfully designed, manufactured, and implemented. 2) The performance of the application of of Remote and Monitoring based Java Remote Method Invocation has a good performance all the systems tested can run and work in accordance with the desired specifications. 3) Feasibility of applications Remote and Monitoring based on Java Remote Method Invocation in terms of usability is very feasible with percentage 82,14 %.

PENGARUH SENSE OF HUMOR TERHADAP KESEJAHTERAAN PSIKOLOGIS MAHASISWA TINGKAT AKHIR

Psychological well-being is the condition of an individual who can accept everything within himself so that his life has purpose and meaning. One of the factors that can support psychological well-being is a sense of humor because a person will be able to view every negative event more positively.
