Creative conservation and Balinese traditional landscape : scenarios for eco city concepts and culturally sensitive tourism development

Bali is internationally recognized as an island possessing a beautiful natural landscape as well as a unique culture. The natural qualities of its mountains, lakes, rivers, rice terrace fields with subak irrigation make Bali an important tourism destination. Cultural Tourism is integral in Bali’s tourism industry providing the basic capital for development1. The social condition of this society that is strongly characterized by religious beliefs, and its nature and ecology also supports this. The conservation and maintenance of this traditional landscape is often forgotten because of government agendas to implement cultural city programs aimed at encouraging tourism development. Despite this, the government is now supporting the program of ‘Bali toward Garden Island’, which aims to sustain the physical and cultural environment of the island towards conservation of its landscape. The implementation of this program includes attention to universal, societal and cultural values as unity indicators, of which the landscape planning of the Balinese characteristics and traditions cannot be separated. Landscape planning is integral in this initiative of character defining the region.

Globalisation is increasingly becoming one of the most important discussions amongst the Balinese people. It has become a national concern about the changes implicating Bali’s environment. Urbanisation, population growth, ribbon development, migration and consumption of energy are important imperatives and necessary evils for growing cities. These imperatives are creating the sprawl of building planning, development information, loss of open spaces, as well as the decline of the identity of cities. Places such as Denpasar City are struggling with increasing population at a rate of 1.94% per year that is causing increase in housing and public facilities demanded by both residents and ex-patriates. Thus land associated with the city has been lost to the rapid development of this cultural landscape.

This paper examines the Balinese traditional landscape and its role in encouraging tourism development that based on the Balinese culture and its ecology. The paper focuses on the planning of city landscape appearance characteristics and seeks to test and adopt the terms ‘creative conservation’ and ‘eco city concept’. By conserving the most important philosophy of the Balinese Tri Hita Karana Concept will better inform all aspects of city development in Bali. This study seeks to offer guidance for the legitimate use of landscape planning especially for city development in Bali.

Tri-component bio-composite materials prepared using an eco-friendly processing route

We report on the blending of three natural polymers, raw cotton, silk and wool, using ionic liquids as the dissolving media. We find that with increased content of wool and silk the thermal degradation temperature of the new bio films increases. This is due to an increase in the hydrogen bond network between the blended polymers. We also investigated the role of the coagulating solvent by coagulating the bio films using water, methanol or isopropanol. Again, we find the coagulating solvent impacts the final properties of the bio films with water shown to coagulated films with the best material properties.

Transformasi rumah tradisional bali di kawasan wisata : sebuah proses perjalanan arsitektur tradisional Bali

The traditional Balinese house is a house traditionally accommodating domestic and sociocultural activities inspired by Hindu Balinese religion. Cultural activities inspiring setting of the house have attracted tourists where the increase has stimulated people to transform their houses through constructing new structures that often change the ideal form and setting of the house. These changes give rise to a question about the form and the setting as owner's interpretation to accommodate their activities. Through visual documentations and interview, this paper explores the transformation in tourism areas as a process of the house development and the needs of spaces to accommodate occupants' activities.

The corrosion inhibition of aluminium alloy 7075-T651 with cerium and Mischmetal di phenyl phosphate

Previous studies have shown that cerium diphenyl phosphate (Cedpp) 3 is a very effective inhibitor of corrosion of aluminium alloys in chloride solutions. This paper describes the results of further studies using electrochemical and constant immersion corrosion tests to compare the effectiveness of Ce(dpp) 3 and Mischmetal diphenyl phosphate Mm(dpp) 3 as inhibitors of corrosion pitting on AA7075-T651 aluminium alloy. The results shows that both Ce(dpp) 3 and Mm(dpp) 3 are excellent inhibitors of pitting corrosion of this alloy in very aggressive environments of continuously aerated 0.1M and 1.0M sodium chloride (NaCl) solutions. Polarisation tests indicate that these compounds act as a cathodic inhibitors by reducing the rate of the oxygen reduction reaction, which results in a decreased corrosion current density and a separation of the corrosion potential from the pitting potential. This inhibition is thought to be due to the formation of a surface film consisting of rare earth metal oxide, aluminium oxide and a cerium-aluminium organo-phosphate complex. Surface analysis data from scanning electron microscopy and X-ray Energy Dispersive Spectroscopy show the complex nature of this protective film. This work further develops our understanding about the mechanisms through which these complex films form, and how inhibition occurs in the presence of these compounds.

An empirical analysis of environmental strategy, eco-controls, environmental and economic performance

 This study provides empirical evidence on the role of eco-controls, in terms of both the style of use and bureaucratic stance towards eco-controls, as a critical mediating variable between an organisation’s level of proactive environmental strategy and its environmental and economic performance outcomes.

Reframing the turn: toward an ethical poetics of eco-elegy & The Counterpart (an excerpted novel)

 This practice-led thesis, comprising of an excerpted literary novel and an extended theoretical essay, explores the relations between ethics, elegy and ecology, and proposes a framework for rethinking an ethical poetics of eco-elegy.

Incorporating carbon footprints into seafood sustainability certification and eco-labels

The seafood industry has become increasingly interconnected at a global scale, with fish the most traded commodity worldwide. Travel to the farthest reaches of the oceans for capture is now common practice, and subsequent transport to market can require hundreds to thousands of miles of travel by sea and air. Refrigeration of seafood products is generally required at all stages of the journey from ocean to dinner plate, resulting in substantial energy expenditure. Energy input for aquaculture (including mariculture) products can also be high, namely due to the large amounts of feed required to support fish growth. As a result of these factors, the seafood industry has a substantial carbon footprint. Surprisingly, however, carbon footprints of seafood products are rarely integrated into assessments of their sustainability by eco-labels, sustainability certification, or consumer seafood sustainability guides. Suggestions are provided here for how carbon footprints could be incorporated within seafood sustainability schemes.

Supramolecular ionic networks with superior thermal and transport properties based on novel delocalized di-anionic compounds

Supramolecular ionic networks based on highly delocalized dianions having (trifluoromethane-sulfonyl)imide, (propylsulfonyl)methanide and (cyano-propylsulfonyl)imide groups were developed and their physical properties were examined in detail. Most of the synthesized compounds were semi-crystalline possessing Tm values close to 100°C; however, amorphous networks were also obtained using aromatic asymmetric dianions. Rheological measurements in temperature sweep tests at a constant frequency confirmed two different behaviors: a fast melting close to the Tm for semi-crystalline materials and a thermoreversible network for liquid transition for the amorphous supramolecular ionic networks. It was found that the amorphous ionic networks showed significantly higher ionic conductivity (10^-3 S cm^-1 at 100°C) than the crystalline ionic networks (10^-6 S cm^-1) and previously reported amorphous citrate ionic networks (10^-5 S cm^-1). The supramolecular ionic networks containing hydrophobic (trifluoromethanesulfonyl)imide groups demonstrated improved water stability and higher thermal stability than the previously synthesized carboxylate ones. Noticeably, the obtained amorphous supramolecular ionic networks combine not only high ionic conductivity and thermal stability, but also self-healing properties into the same material.
