Abstract

Wood has been widely used as building materials. The trends of using wood as construction materials in a building are keep increasing because the positive trend in construction expertise to use wood as building construction. Wood can be used as building materials such as structural construction, decking, roofing, flooring, cladding, furniture and interior. Wood is chosen because it is easy to work, flexible in design, high energy efficiency, low embodied energy, low global warming potential, fire resistance, and importantly wood is renewable and recyclable resources. Each country has their own regulations related to the application of wood as materials in high rise building. However, these regulations stimulated the expertises to demonstrate that wood is capable to be high-rise building materials and fulfil the safety building requirements. Keywords : wood, high-rise building, environmentally friendly

Abstract

Current issues of energy sector in Indonesia can be summarized as depletion of fossil energy reserves which is dominated by fuel oil and coal. Oil production continues to decline and the increase in oil fuels demand lead to increase imports of crude oil and oil fuels. To use lignocellulosic biomass waste has become a major alternative to replace fossil fuels and chemical feedstocks production. In 2015, total rice production in South Kalimantan reached 2,140,276 ton and rice straws were abundant waste which could be utilized as raw material for bioethanol production. Pretreatment process of lignocellulose is a crucial step to remove lignin because of the complex chemical cross-linking between chemical components. Delignification of lignin can increase the accessibility and digestibility of enzymatic, and help to promote enzymatic hydrolysis. Nowadays, pretreatment process with green chemistry method is continuesly developed by researcher to reduce the production costs and thus avoid adverse effects on human and the environment. This article disscussed about green methods for pretreatment of lignocellulosic material using deep eutectic solvent (DES) to increase second-generation bioethanol production in South Kalimantan.

Abstract

Cross laminated timber (CLT) is an engineered wood product as a laminated board that was arranged in cross order and applied as floor, roof, and wall. This product is an innovation in overcoming the scarce of wood material especially in large diameter and high quality as a building material. The review discusses the history of CLT, the characteristics, and its developments. CLT was first developed in Europe especially in Austria and Germany and then spread around the world. CLT has superiority in term of characteristics such as renewable, recyclable, easy to design and form, good insulation, energy efficient, fire resistance, good seismic characteristics, and also acts as a carbon sink that relieves the stress of global greenhouse gasses effect. CLT also has the strength that comparable to concrete and steel, and suitable for high rise building structure purposes. CLT is a prefabricated product and has advantages such as time saving, labor efficient, minimal post construction waste, and less disturbance to the environment during construction. CLT was developed outside Europe and reached North America, New Zealand and Indonesia. The barrier in adopting CLT are the lack of information of the products. One of the solution is to increase the awareness and the product knowledge.Keywords : architecture, building constructions, cross laminated timber, engineered wood
