Abstract

The use of a smartphone as a mobile learning tool in schools is controversial. On the one hand, the teacher prohibits it because it would interfere with the learning process in the classroom; and on the other hand, the teacher saw a lot of potentials can be used from mobile technology. The goal of this study is to describe how the development of secondary schools in Indonesia can facilitate students through the use of mobile learning with the hope that it can be taken at the school level policies to strengthen the existing learning system so that students can achieve optimal learning competencies. This research used descriptive qualitative evaluations to make observations on the application of mobile learning in several secondary schools in several regions in Indonesia during 2015. The results of this study indicate that some of the schools that have implemented mobile learning have a tendency that mobile learning was not planned and structured as a school program; so that the advantages of mobile technology has not been effectively used. Two important things to solve this condition are the availability of government policy and improving teachers literacy in managing mobile learning application.

Abstract

 In this work, a nanocomposite photocatalyst was fabricated by growing zinc oxide (ZnO) and titanium dioxide (TiO2) on the sand as a substrate. The initial sand/ZnO was fabricated via sol-gel immersion method for 4 h at 95℃. Furthermore, the sand/ZnO/TiO2 was fabricatedusing hydrothermal method for 5 h at 150℃. Based on field emission scanning electron microscopy (FESEM) analysis, the fabricated sand/ZnO/TiO2 consists of random formation of hexagonal ZnO nanorods and two pyramidal spindle ends of TiO2 nanorods. The addition of TiO2 on top of ZnO nanorods increased the number of active sites which enables more contaminants to be absorbed thus enhanced the photocatalysis process. Moreover, based on the micro-Raman spectra, the synthesized TiO2 was in rutile phase and the ZnO peak was unobservable due to the overlapping with TiO2 peak. Based on its morphological and structural properties, the fabricated sand/ZnO/TiO2 nanocomposite was potential to be applied as photocatalyst.

Abstract

In this work, graphene oxide (GO) and titanium dioxide (TiO2) were used as an additive to fabricate the nanofiltration (NF) membrane. GO was synthesised via electrochemical exfoliation method utilising sodium bis(3,5,5-trimethyl-1-hexyl) sulphosuccinate (AOT4) surfactant. The synthesised GO was then used to fabricate PVDF-based NF membrane namely PVDF/GO_TiO2 via non-solvent induced phase separation (NIPS) method. The effects of embedded GO and TiO2 on the morphology and structural properties of PVDF/GO_TiO2 were investigated by using field emission scanning electron microscopy (FESEM) and micro-Raman spectroscopy. The finding shows that PVDF/GO_TiO2 present thin and dense top layer supported by macro-voids sub-layer with sponge-like layer at the bottom. Based on its morphology, the fabricated PVDF/GO_TiO2 membrane is potential to be applied as membrane filtration for water treatment application.
