Knowledge Discovery Database (KDD)-Data Mining Application in Transportation

In this paper, an understanding and a review of data mining (DM) development and its applications in logistics and specifically transportation are highlighted. Even though data mining has been successful in becoming a major component of various business processes and applications, the benefits and real-world expectations are very important to consider. It is also surprising to note that very little is known to date about the usefulness of applying data mining in transport related research. From the literature, the frameworks for carrying out knowledge discovery and data mining have been revised over the years to meet the business expectations. In this paper, we apply CRISP-DM for formulating effective tire maintenance strategy within the context of a Malaysian's logistics company. The results of applying CRISP-DM for tire maintenance decisions are presented and discussed

Model Multiliterasi Kritis dalam Pembelajaran Siswa Sekolah Dasar

The critical multiliteracy model always involves students to be active in asking questions or making their own conclusions. Through challenging multiliteracy learning students are expected to be able to have confidence, be smart, communicative, brave and have character. In this study using the literature review method. Based on the results of the research conducted, critical multiliteracy models mostly show success in the learning process and learning outcomes. Keywords : Critical multiliteracy, elementary school student

Sistem Informasi Administrasi Pengajuan Surat Pengantar pada Kelurahan Meruya Utara

Pelayanan di kelurahan umunya merupakan pembuatan surat pengantar yang juga dikelola oleh pihak Ketua RT dan RW dengan surat pengantar RT/RW. Surat pengantar merupakan persyaratan utama untuk proses administrasi kependudukan lainnya yang dibutuhkan masyarakat. Pembuatan surat pengantar tentunya harus terlayani dengan baik agar meningkatkan kepercayaan pada masyarakat dan meningkatkan kualitas pelayanan pada kelurahan. Tujuan dari penelitian ini, yaitu menghasilkan sistem pengajuan pembuatan surat pengantar RT/RW dan kelurahan berbasis website yang dapat di akses dimana saja dan kapan saja. Sistem ini mengelola data-data dan pembuatan pengajuan surat pengantar pada kelurahan Meruya Utara untuk Staf Kelurahan dan RT/RW. Pada penelitian ini, pengembangan sistem informasi ini menggunakan metode Waterfall. Penelitian diawali dengan melakukan observasi pada kelurahan Meruya Utara, melakukan wawancara dengan pihak Kelurahan Meruya Utara, menganalisa data, lalu merancang dan membuat sistem usulan serta melakukan pengujian pada sistem. Sistem yang dikembangkan dapat menjadi solusi atas pemberkasan yang masih dilakukan secara manual dengan menjadikannya terkomputerisasi sehingga dapat mengurangi penumpukan berkas yang ada di Kelurahan Meruya Utara

Influence of Mg Doping on ZnO Nanoparticles for Enhanced Photocatalytic Evaluation and Antibacterial Analysis

Abstract In this research, a facile co-precipitation method was used to synthesize pure and Mg-doped ZnO nanoparticles (NPs). The structure, morphology, chemical composition, and optical and antibacterial activity of the synthesized nanoparticles (NPs) were studied with respect to pure and Mg-doped ZnO concentrations (0–7.5 molar (M) %). X-ray diffraction pattern confirmed the presence of crystalline, hexagonal wurtzite phase of ZnO. Scanning electron microscope (SEM) images revealed that pure and Mg-doped ZnO NPs were in the nanoscale regime with hexagonal crystalline morphology around 30–110 nm. Optical characterization of the sample revealed that the band gap energy (E g) decreased from 3.36 to 3.04 eV with an increase in Mg2+ doping concentration. Optical absorption spectrum of ZnO redshifted as the Mg concentration varied from 2.5 to 7.5 M. Photoluminescence (PL) spectra showed UV emission peak around 400 nm. Enhanced visible emission between 430 and 600 nm with Mg2+ doping indicated the defect density in ZnO by occupying Zn2+ vacancies with Mg2+ ions. Photocatalytic studies revealed that 7.5% Mg-doped ZnO NPs exhibited maximum degradation (78%) for Rhodamine B (RhB) dye under UV-Vis irradiation. Antibacterial studies were conducted using Gram-positive and Gram-negative bacteria. The results demonstrated that doping with Mg ions inside the ZnO matrix had enhanced the antibacterial activity against all types of bacteria and its performance was improved with successive increment in Mg ion concentration inside ZnO NPs
