While reading activity is a complex phenomenon, recent research on reading strategies has not provided comprehensive explanation of the role and perceptions of teachers regarding appropriate reading strategies helping students with learning difficulties. This paper is aimed to provide a sketch of the teacher's views and strategies to facilitate students with appropriate reading strategies. EFL teachers have different kinds of reading strategies applied in the classrooms. This study has found that three groups of teachers teaching in excellent accredited public schools, good accredited public school and very good Islamic private school use various strategies during the teaching of reading. Teachers' perceptions on the teaching of reading strategies are closely related to their readiness with knowledge about reading strategies, students' reading problems and their belief. This study suggests that EFL teachers and future researchers need to continuously investigate effective teaching of reading skill in relation to students' reading strategies.

The potential of thin layer in many applications has led to research on the development of many new materials and their fabrication methods. This study aimed to synthesize a thin layer of ZnO using the facile and low-cost sol-gel spin coating method. The ZnO thin layer is deposited on a glass substrate and analyzed to observe the influence of the deposition variables such as heating and rotation speed, and its aging. The characterization methods include the identification of the formed phase using X-Ray Diffractometer (XRD), and the microstructure and elemental composition using Scanning Electron Microscopy (SEM) coupled with EDS (Energy Dispersive Spectrometer). The study shows that a thin layer of ZnO is successfully deposited on a glass substrate by heat treatment at temperatures of 300 oC and 500 oC. Furthermore, XRD reveals that higher heating temperatures result in higher diffraction peak intensity. At a heating temperature of 300 °C crystals are formed but are not yet perfectly oriented, while they are at 500 °C. On the other hand, higher spin coating rotation speed gives rise to lower intensity of diffraction peak. The ZnO crystallization is easier to form in the coating process with a lower rotation (1500 rpm). Interestingly, the thin layer is stable over time where there is no significant change in each sample, both in terms of intensity and width of the ZnO crystal peak. The results indicate that gel precursor aged less than two days can form ZnO crystals. Finally, SEM results show that the surface morphology of the ZnO layer heated at 500 oC has an average grain size of 300 nm. Based on the cross-sectional results of SEM shows that the higher the coating rotation speed has resulted the thinner of the ZnO layer, where the thickness of the resulting layer is on order >5 mm.

The purpose of study was to determine kinetic parameters and inhibitory effect of Mg2+ ions on pectinase. Activity test performed at pH 4,5 temperature 55oC for 50' with 10 mm concentrations of each ion 0-10mm. Galacturonic acid content, as product of pectin substrate hydrolysis, was used as basis for determining activity and analyzed by visible spectrophotometry. At concentrations 2 and 4 mm Mg2+ act as an activator, but at concentrations 6, 8, and 10 mM as inhibitors. The value of KM with and without inhibitors is almost same, that is 0.3145% and 0.3105% but value of Vm from both are different, that is 80,645 μg.ml-1.minute-1 and 62,112 μg.ml-1.minute-1. The conclusion that type of inhibitory pectinase with Mg2+ is a non-competitive inhibition. The inhibition constant value (Ki) is 26,84.

[Title: The Conceptual Profile of Prospective Biology Teacher FPMIPA IKIP Mataram]. The conceptual profile is a tool for analyzing the style or process of thinking, so the profile of understanding concepts is very important to study as a basis for designing and improving the quality of learning. This research is a descriptive study that aims to identify and explain the conceptual profile of prospective biology teacher FPMIPA IKIP Mataram. The subjects in this study included all biology students who regularly program evolutionary courses. The open-ended question is designed to collect conceptual profile data on the evolutionary biology students from FPMIPA IKIP Mataram. Identification or determination of conceptual profile is based on student responses or answers. Based on the results of the research and the limitations of the discussion, it is recommended that the development of textbooks that are free of misconception as a learning resource for valid biology prospective teacher, then lecturers as instructors, continue to study and teach about attitude, namely scientific attitudes, or thinking dispositions, and/or integrating attitudes in the lecture process. Besides that, in the lecture or learning process, the lecturer must facilitate or empower the style or process of thinking of students with various learning methods or strategies that emphasize thinking processes, including formal reasoning, and analogical teaching strategy.
