Abstract

Pemahaman tentang fenomena sistem tata surya  membutuhkan daya imaginasi yang cukup. Hal ini merupakan salah satu kesulitan dalam memahami materi tentang sistem tata surya, sehingga diperlukan adanya visualisasi untuk membantu mengatasi kesulitan tersebut. Salah satu visualisasi adalah dengan menggunakan program visualisasi 3D. Pembuatan program diawali dengan identifikasi masalah dan persiapan perangkat lunak. Dalam hal ini program yang digunakan adalah VRML(Virtual Reality Modelling Language). Pelaksanaan pembuatan program dimulai dengan memodelkan gejala-gejala fisis yang terkait dengan fenomena sistem tata surya. Bahasa pemrograman VRML hanya mampu melakukan perhitungan dasar yang sangat sederhana. Untuk perhitungan data yang kompleks digunakan bantuan Microsoft Office Excel. Data yang dihasilkan dari perhitungan menggunakan Microsoft Office Excel kemudian dimasukkan ke dalam list program VRML. Hasil penelitian berupa pemodelan sistem tata surya yang diintergrasikan dalam e-learning berbasis web. Untuk menampilkan hasil program ini digunakan browser Cortona VRML player. Tampilan 3D yang dihasilkan menarik dan interaktif. User dapat mengamati model 3D dari berbagai sudut pengamatan dengan menggunakan toolbar yang tersedia pada browser. Kata kunci : VRML, visualisasi 3D, sistem tata surya

Abstract

Perkembangan teknologi informasi telah berkembang pesat dalam bidang pendidikan dengan lahirnya e-learning. E-learning dapat membantu guru dalam memantau keaktifan siswa dengan penugasan, forum diskusi maupun aktivitas lain, sehingga karakter dapat dideskripsikan melalui e-learning. Tujuan dari penelitian ini adalah mengembangkan Software Learning Management System (LMS). LMS adalah aplikasi perangkat lunak untuk kegiatan online, program pembelajaran elektronik (e-learning program) dan isi pelatihan. Selain itu, penelitian ini juga menyelidiki respon dari siswa terhadap LMS dan menguji keefektifannya dalam meningkatkan pemahaman konsep serta mengembangkan karakter siswa. Metode yang digunakan dalam penelitian ini adalah metode penelitian pengembangan. Uji produk menggunakan Pre Experimental Design dengan jenis Pretest and Posttest One Group Design. Instrumen penelitian berupa angket uji ahli, angket tanggapan, tes tertulis dan lembar observasi karakter. Teknik analisis data uji kefektifan menggunakan uji gain. Hasil tanggapan siswa untuk keseluruhan aspek mendapatkan prosentase diatas 82,5% kategori sangat baik. Hasil uji gain pemahaman konsep sebesar 0,56 dengan kategori sedang, artinya LMS efektif meningkatkan pemahaman konsep siswa. Sedangkan uji gain karakter 0,16 kategori rendah, artinya belum efektif mengembangkan karakter siswa.

Abstract

The current topic that is interesting as a solution of the impact of public service improvement toward vehicle is License Plate Recognition (LPR), but it still needs to develop the research of LPR method. Some of the previous researchs showed that K-Nearest Neighbour (KNN) succeed in car license plate recognition. The Objectives of this research was to determine the implementation and accuracy of Otsu Method toward license plate recognition. The method of this research was Otsu method to extract the characteristics and image of the plate into binary image and KNN as recognition classification method of each character. The development of the license plate recognition program by using Otsu method and classification of KNN is following the steps of pattern recognition, such as input and sensing, pre-processing, extraction feature Otsu method binary, segmentation, KNN classification method and post-processing by calculating the level of accuracy. The study showed that this program can recognize by 82% from 100 test plate with 93,75% of number recognition accuracy and 91,92% of letter recognition accuracy.

Abstract

Issue handling of inadvertence situations in the decision-making process of recruiting new employees at PT. Warta Media Nusantara that use criteria value of interviews, field test, a psychological test and medical check-up requires Multi Attribute Decision Making (MADM) as an auxiliary method of decision-making on the prospective eligible employee to be accepted in the company. There are various MADM methods, such as Simple Additive Weighting (SAW) method and Weighted Product (WP) method. Both of these methods are known as the most common method used in handling MADM issues, so in this study both methods are applied to the DSS and analyzed the differences in terms of obtained results and the execution time required for each method. The results of the study of the application of SAW and WP methods in the recruitment of new employees DSS there are some differences in the results of the candidates rank order and the differences in execution time of each method. The differences in rank order of these methods are due to the effects of alternative values, weighting criteria, and the calculation method. WP method is able to provide more rigorous result than SAW method, while the difference in execution time of SAW and WP methods explains that the execution time of SAW method relatively quick because SAW calculation method has a simpler process than the process of WP calculation methods

Abstract

      Astronomi merupakan cabang ilmu yang mempelajari benda-benda langit di luar atmosfer bumi. Materi astronomi tidak dapat dipelajari secara langsung karena tidak dapat dihadirkan di dalam kelas. Melalui media pembelajaran diharapkan fenomena-fenomena alam yang berhubungan dengan peristiwa astronomi dapat dijelaskan kembali dengan lebih menarik. Produk dari penelitian ini, salah satunya dengan dikembangkanya program komputer berupa visual novel pada materi astronomi subbab bintang, tata surya, dan lubang hitam menggunakan Ren’Py Launcher. Media pembelajaran berupa cerita bergambar yang di dalamnya menjelaskan mengenai materi astronomi. Metode penelitian yang digunakan berupa linear sequential model 4D (Define, Design, Develop, dan Disseminate). Media divalidasi oleh pakar media dan pakar materi. Pengambilan data dilakukan melalui metode angket dengan instrumen meliputi angket uji kelayakan media, angket uji kelayakan materi, dan angket responden mahasiswa. Pengolahan data hasil angket menggunakan metode penskoran dengan Skala Likert. Hasil pengolahan data pengujian kelayakan oleh pakar media menunjukkan penilaian baik demikian pula pada pengujian oleh pakar materi dengan perolehan skor sebesar 81,43% dan 86,43%. Hasil yang ditunjukkan oleh angket responden mahasiswa menunjukkan hasil baik dengan persentase 77,0%. Media pembelajaran selanjutnya disebarkan melalui internet menggunakan layanan Cloud Service Google Drive.

Abstract

Measurements with using  micrometer and vernier caliper is one of the subject taught in high school level. The problem faced is the small size of the tool making it difficult for students when the teacher demonstrates the tools. The solution to solve this problem is by develop a learning media with the use of Construct 2 software. The development of this media follows the 4D model which consists of 4 stages of development that is defining, designing, developing, and disseminating. Validation test by experts and feasibility questionnaires by users of teachers and students have been done to determine the feasibility of the learning media. Aspects assessed by the expert is the aspect of media feasibility in terms of visual communication design, software engineering aspects and aspect in term of learning contents. The media feasibility test by users is done in SMA Muhammadiyah 2 Magelang and SMAN 1 Pecangaan Jepara. The data obtained show that the media created have very good categories in terms of visual communication design and learning contens, as well as good categories in terms of software engineering aspects. The media created are also rated very well by students and teachers.
