Rice straw is agricultural waste which hasn’t been used optimally yet, especially in Indonesia. Meanwhile, rice straw contains cellulose that can be used form composite such particleboard. In this study, the physical and chemical properties of particleboard made of rice straw particle and polypropylene from plastic waste as adhesive were investigated. The rice straw and polypropylene compositions were varied: 30:70, 40:60, 50:50, and 60:40 wt.%. The rice straw particle sizes were varied for 40 mesh, 50 mesh, and 60 mesh for each composition. X-Ray Fluorescent has been used to measure the chemical composition of our particleboard. The density of particleboard is 0.59-0.77 g / cm3. Its thickness swelling is less than 2%. Both density and thickness swelling has met the requirement for Indonesian Standard of particleboard. Our results showed that the density of particleboard strongly depends on rice straw particle size. As the particle size decreases, the density increases. The particle size of rice straw affects the thickness swelling of particleboard. The thickness swelling decreases as the particle size decreases. The major constituents of our particleboard are the SiO2, CaO, K2O. Our finding showed that the particle size has an essential role in the physical properties of particleboard.

Published: March 2020

Abstract
The formation of traditional Javanese villages often began with the establishment of a center for activity, generally a traditional mosque. Currently, several historic mosques in rural areas have survived with various changes. This study aims to explore the trends in the transformation of mosques. The research focuses on the area around Jatinom Village, Klaten, which is famous for its Islamic and Javanese culture. It assesses five historic mosques in the villages of Jatinom, Kadirejo, and Belangwetan. The research adopts a comparative case study method using observations, literature review, and interviews. The results show that (1) the mosques have changed from its traditional form; (2) four elements remain the same: the 2-3-tiered roof shape, the soko guru structure, the mihrab, and the main three doors in the front façade; and (3) two elements mostly change: the façade and the terrace. Understanding this trend would help the community to anticipate in preserving the historic mosques.

Abstract
This paper illustrates techniques based on multi-criteria evaluation for categorising desertification in the north-west of Iraq. Desertification is recognised as not only one of the major dilemma threatening human communities but also reduces productivity such that the whole economy is affected. The aim of this paper is to produce a desertification map for the study area that identifies risk zones through modelling and mapping by using Analytical Hierarchy Process (AHP), which is one of the Multiple Criteria Decision Making, based GIS for the selection process. In order to produce a desertification categorisation for the study area, numbers of criteria were identified depending on the questionnaires provided by experts. The produced desertification hazard map shown in ‘figure 3 indicates that 3.98% of the area is under very high sensitivity to desertification. The remaining area under high sensitivity is 7.25% and moderate sensitivity is 25.97%. The most hazardous areas are found in the middle and south parts of the study area. This paper including its methodology can be extrapolated to different desertification problems.
