Abstract: Land use changes are a key driver in global environmental changes and had a significant impact on the climate at all scales. Various human activities that took place thousands of years ago have an impact on the earth's surface. Today, with the limited supply and high demand, land use crisis became a big issue for the most countries. Changes in land use are not actually only providing a history of the area, but it also describes the way of life of its local communities. In the interdisciplinary research for land use study, cultural values, knowledge and perceptions of knowledge has been recognized as a major factor in determining the adopted approach applied in land use management in that area. Therefore, this paper tries to evaluate the role and potential of the integration of TLEK and GIS in mapping the series of changes in land use.Keyword: Local knowledge, TLEK, land use mapping & conceptual framework

The increase of tourism activity at sub watersheed Konto hulu make land use diversion. Land diversion made land erotion, sedimentation and rubbish. In order to reduce the impact, community make their own local wisdom. This research has been carried out the impact from tourism activity in the land use diversion at sub watersheed Konto Hulu.

Abstract: This paper is trying to analysis and proposes some design of grey water system in The National University of Malaysia (UKM) mosque in order to save environment. With proper grey water treatment, UKM Mosque will contribute to save water and UKM’s environment. This successful water treatment is also can be an alternative model to apply in another building. This environmental issue, especially water was realized by Universiti Kebangsaan Malaysia (UKM) by starting to be a first pioneer in Green & Sustainability Campus in Malaysia. Although UKM is located in water-rich country, still UKM try to commit to save environment as well as manage its environment aspect. The usage of water in UKM itself is categorized in high level. UKM have around 20.000 students and most of them are dwelling in campus. For big campus like this, UKM had one main Mosque which accommodates some daily worship of Moslem as the majority one. For activities like ablution, washing and bathing, UKM Mosque had produce quite big amount of grey water. Grey water itself is residual water that still fresh and can be recycled for some purposes such as landscape irrigation and cleaning service. One alternative method to treats the grey water is by the usage of filter wells.

Abstract: This paper presents a study of the application of the theory of rainwater harvesting for a low income flat in West Jakarta. The background of this study is that Jakarta as a capital city of Indonesia is actually experiencing water crisis because of the rapid population growth and the building construction. This rapid development in consequence affects a reduction on the ground water supply. Therefore, this study analyse the amount of rain water that can be an alternative water supply particularly for a low income flat. This study focused on the water supply for the flushing toilet. To accommodate that objective, a brief calculation of water catchment area and the amount of water that can be harvested has been conducted. The results showed that in general the water supplied by the rain water harvesting can provided 100% annually, but since the precipitation in August is relatively low, in consequence, the water suply should be provided by the local government water company (PDAM).

Abstract: Maintenance performance is a key aspect in sustaining the RWH system. This is to ensure the maximum value of installing the RWH system as well as ensuring the system performs throughout the building's lifetime. Two instruments were used during this research namely physical condition survey and questionnaire survey. The results from both instruments demonstrated cross-combination finding via maintenance performance quadrant at the end of analysis. Based on the study at 16 government buildings throughout Malaysia, the results show the majority of buildings need improvement in terms of their maintenance management, while two buildings have bad practice, which needs total refurbishment for the RWH system as well as their maintenance management. In conclusion, the physical condition of the RWH system for government building in Malaysia is regarded good and safe implemented. However, the maintenance performance can be improved with a proper maintenance guideline and management policy by the organization involved.

Abstract: This paper will discuss on issues of using alternative fuel (bio jet fuel) for 50% mixing or replacing current Jet A/ Jet A-1 fuel in relationship towards aircraft fuel systems. Two key issues aviation biofuel; Technical Risk and Quality Risk will be evaluated. Technical risk, such as storage stability for biological growth, thermal stability in relation to fuel system components coking, the outcomes from combustion properties and material compatibility to the engine system and discussions on the level of the trace of contamination like metals or micronutrients. In quality risk, the issues need to be measured: the inconsistency of the products such as the source dependencies, robustness control and fragmented enterprise. These two issues need to be measured in order to create a clear pathway for Air Transport in sustainable manner, where further research towards reliability and sustainability for future aircraft performance and maintenance can be correlated.

Abstract: Daylighting strategies and control of it, plays a significant role in energy efficiency and provision of visual comforts in buildings. This study conducted a review of literature and observation in a hot and dry region of Iran in order to investigate daylighting strategies and control of it by shading devices in the vernacular residential buildings. The results show thatdaylight in vernacular rooms was provided through door, window, Rozan, Moshabak, and Goljam. These components were equipped with thevertical and horizontalshading devices such as Orsi, Sarsayeh, Tabeshband and Kharakpoushto control the sunlight. The vernacular lighting strategy was in response to the energy efficiency and provided visual comfort.The vernacular concepts and schemes still can be adopted and reused by architects and developers. The study recommends appropriate daylight schemes and shading devices in design phase to achieve energy efficiency in new residential buildings.

Abstract: This paper presents the study of the integration of Photovoltaic (PV) module and green roof on a building. Essentially, this integration could be considered as an extend understanding of a concept, namely “Biomimicry”. Biomimicry, in brief, is an approach that mimics the philosophy of flora, fauna or entire ecosystems and these are emulated as a basis for design. The implementation of this approach in this project is to utilize photovoltaic and green roof as a part of a building in terms of imitating the plant biological activity. To accommodate the process of that implementation, a simulation study was conducted by using software called “EnergyPlus”. The simulation focused on investigating heat transfer over those two technologies. The deliverables of this study are the electricity production and the surface temperature reduction. A comparison study on energy transfer is also presented here to illustrate the application of the biomimicry concept on an architectural design.

Abstract: Palu has onshore wind potential 3.6 m/s in average and offshore 5.3 m/s in average. Based on the weather condition which has temperature between 27.3 degree Celcius - 37 degree Celcius, Palu has solar potential with an average insolation value 6.6. Shortage that is quite often happen in Palu (Indonesia) can be solved by installing 19.5 MW PV and 9.9 MW wind that can produce electricity of 234.1 MWh per day with total investment cost of US $129,005,860. By replacing some diesel generators with PV and wind and combined with 104.5 MW existing capacity, the total fuel can be saved is 16,599 gal per day and the total reduced CO2 production is 167 kg per day.
