PENGARUH METODE VAKT (VISUAL, AUDITORY, KINESTETHIC, TACTILE) TERHADAP KETERAMPILAN MENULIS PERMULAAN PADA ANAK AUTIS KELAS II DI SEKOLAH AUTIS HIPERAKTIF PUTRA HARAPAN BUNDA

Penelitian ini bertujuan untuk mengetahui pengaruh metode VAKT terhadap keterampilan menulis permulaan anak autis kelas II di Sekolah Autis Hiperaktif Putra Harapan Bunda. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitian kuasi eksperimen Single Subject Research (SSR). Desain yang digunakan yaitu A-B-A’. Subjek penelitian merupakan seorang anak autis kelas II Sekolah Dasar. Teknik pengumpulan data dalam penelitian ini menggunakan metode tes unjuk kerja dan observasi. Instrumen penelitian yang digunakan berupa soal tes unjuk kerja dan panduan observasi. Data yang diperoleh dianalisis dengan menggunakan statistik deskriptif dalam kondisi dan analisis antar kondisi yang ditampilkan dalam bentuk tabel dan grafik. Hasil penelitian ini menunjukkan bahwa metode VAKT berpengaruh terhadap keterampilan menulis permulaan pada anak autis. Hal ini dikarenakan pada proses pelaksanaan pembelajarannya, anak autis dapat belajar secara nyata mengenai bentuk huruf dan pengucapannya melalui indera pengelihatan, pendengaran, gerakan dan perabaan, sehingga memudahkan anak untuk belajar menulis. Pengaruh metode VAKT ditunjukkan dengan persentase ketercapaian tes unjuk kerja yang dilakukan oleh subjek mengalami perubahan ke arah positif (meningkat) setelah diberikan treatment berupa metode VAKT. Persentase ketercapaian tersebut menunjukkan adanya perubahan level yang terjadi pada perbandingan antar kondisi intervensi dengan baseline-1 (B/A) sebesar 15% yaitu dari 55% menjadi 70%, dan perbandingan antar kondisi baseline-2 dengan intervensi (A’/B) sebesar 30% yaitu dari 70% menjadi 100%

Trustworthy-based efficient data broadcast model for P2P interaction in resource-constrained wireless environments

AbstractIn a decentralised system like P2P where each individual peers are considerably autonomous, the notion of mutual trust between peers is critical. In addition, when the environment is subject to inherent resource constraints, any efficiency efforts are essentially needed. In light of these two issues, we propose a novel trustworthy-based efficient broadcast scheme in a resource-constrained P2P environment. The trustworthiness is associated with the peerʼs reputation. A peer holds a personalised view of reputation towards other peers in four categories namely SpEed, Correctness, qUality, and Risk-freE (SeCuRE). The value of each category constitutes a fraction of the reliability of individual peer. Another factor that contributes to the reliability of a peer is the peerʼs credibility concerning trustworthiness in providing recommendation about other peers. Our trust management scheme is applied in conjunction with our trust model in order to detect malicious and collaborative-based malicious peers. Knowledge of trustworthiness among peers is used in our proposed broadcast model named trustworthy-based estafet multi-point relays (TEMPR). This model is designed to minimise the communication overhead between peers while considering the trustworthiness of the peers such that only trustworthy peer may relay messages to other peers. With our approach, each peer is able to disseminate messages in the most efficient and reliable manner

A Case Study of Using an Object-Relational Paradigm in Building a Web Database Application

In this paper, we would like to share our experiences in building a web database application using an object-relational paradigm. The system we built is basically an online system for casual tutors to claim their work for payment. At the design stage, we use an object-oriented design. Since the database backend is a relational database management system (i.e. Oracle), which also supports some object-oriented features, we need to apply a transformation methodology to map our object-oriented design into relational tables incorporating some object features in Oracle. Once the necessary object types and tables have been created, at the programming stage we use a PHP scripting language accessing the Oracle database where the data is stored
