Location of Resort

Green ResortLocation of ResortNear Mamam BeachCharacteristic of Mamam Beach:Wind is blowing from East to WestWaves are destructive at an average of 16 waves per minuteLociLess than 500m from shoreMore than 1500m from Jetty

Reason for locationConvenience for trialToilet next to resortHuts such as Beberek Hut are near thereHas a large area of coastline Convenient point to go to nearby attractions such as Chek Jawa and Balai Quarry

Location of Resort: Wind BreezeThe area is breezy, with most wind coming from the EastThis can act as a natural source of cooling the area downLocation: Sea ViewThe view is towards the sea, and may also overlook the balai quarry behind it

Obtaining Energy: Solar EnergySolar Panels can be placed on top of the resorts to maximise the intake of sunlightThe solar panels can be tilted towards the sun at different times of the day so it will gain and store energy for the nightStoring Energy: Solar CellsIt works by absorbing sunlight and the negatively charged electrons would knock loose from their atoms, producting electricityEfficiency can be boosted by adding silver nanoparticles , where they act like mirrors and concentrate light to be concentratedSolar Cells: Dye Sensitized Thin-FilmA transparent conducting oxide (TCO) is deposited on a transparent substrate, glass or plastic, to make two electrodesTitanium dioxide is a semiconductor and is coated on one of the electrodes to allow electrons to pass through to the other electrodesThe electrodes are coated with organic dye

DSTF: AdvantagesExcels in a wide range of light conditions at various angles; flexible, lightweight and robustDSTF devices generates more energy in diffuse lighting conditions Does not suffer from angular dependence of sunlightDSTF can generate more power over extended periods of time than competing silicon technology.DSTF: AdvantagesEfficiency of DSTF does not degrade with increased temperatureUses inexpensive and eco-friendly nanomaterialsObtaining Energy: Hydro electricityThe dams can be built between Pulau Ubin and ChangiElectricity will be generated and is sufficient for the whole islandThe electricity is renewable and does not affect much of the biodiversity in Pulau Ubin

Hydro Electricity: AdvantagesClean source of energyRenewableAble to produce energy for both Pulau Ubin and Changi areaCan be considered to be an additional tourist attraction at Pulau UbinFacilities: Swimming PoolSolar energy have to be stored in large water tanks, and using it as a natural swimming pool would be a eco friendly choiseThe solar energy can also be stored in a central heater to heat water used for bathing

Facilities: Sauna and steam bathsThe solar energy can be used to heat saunas, instead of using coalThe steam baths is heated with the solar energyEco friendly hotelOur hotel practise eco friendliness, which include serving water only when askedAlso, our toilet bowls are constructed which uses minimal water or no water at allAlso, eco friendly light bulbs and LED lights which require minimal energy are used to illuminate our hotel 17Zero-Energy Building (ZEB)A building's use with zero net energy consumption and zero carbon emissions annually.It can be used autonomously from the energy grid supply energy can be harvested on-site.

BedZED - zero energy housing in the UKOur resort will be built ZEB-formatted.Various microgeneration technologies such as solar cells or wind turbines would be used Skylights would provide 100% of daytime illumination. Night time illumination is done with fluorescent and LED lighting that use 13 waves/min2nd min153rd min134th min155th min19

Physical ImpactCoastal ErosionOccurs through the action of currents and destructive waves Sediment is transported along the coast in the direction of the prevailing currentHouses and our Resort may be destroyed due to the eroding of the shoreBeachfront will be eroded and this is not welcomed by tourists

Method and SolutionsThe shore already has a sea wall to prevent it from being erodedHowever, there are disadvantagesIt is easily damaged as the base of the seawall may be undercut by backwashCausing eventual collapse of the sea wallHence, having the sea wall only is not enoughMethod and SolutionsGroynes will be implemented to solve the problemThey are built at right angle to coastlineThe longshore drift at Mamam beach will be slowed down and thus reduces the pressure on the sea wallHence prevents and slows down erosionPhysical barrier to stop sediment transport in the direction of longshore drift

Method and SolutionsTrap sediment from longshore drift which builds up a beachThe beach will be appealing to touristAesthetically appealing as they blend well with the scenery, hence tourists will not find it disturbingEffective and only cost around $350,000 each

Groynes in SitgesFinal MethodSea Wall accompanying with GroynesThe Sea Wall will be behind the Groynes and the Groynes are connected to the wall

Similiar to the pictureThe cliff is changed into the shore in our case

Green ResortTourist TrailAims to showcase the biodiversity, rustic and historical aspect of Pulau UbinStarts at 7.30am and ends at 10.30amIn time for low tide for viewing of Chek Jawa Transport: Green Vehicle and Walking7 stations and 3 resting stops

Station 1 Beberek HutRest for the start of the trailBalai QuarryThe History of the Quarry will be explainedOpen-pit mine from which rock or minerals are extractedCurrent situation whereby Indonesia banned the export of granites to Singapore

Station 2Chek Jawa via Punai HutEstimated to arrive there at 8.30amLow tide; able to see the rare species of marine lifeExpected to see flora and fauna of Check JawaBroadwalk tour will be includedSpecial request will be made if tourists want to walk on shoreBreakfast to eat at Punai Hut

Station 3 via Green VehicleTourists will take the green vehicle to ( Wei Tuo Fa Gong Temple)Buddhist religion will be explained there Wei Tuo is a devoted guardian and an honored bodhisattva of Buddhist monasteries Guards the Dharma and the objects of the Dharma

Station 4 - 5Ubin QuarryFollow up on history of the quarries in UbinIn the 1970s, there are more than 10 mining companies on the island with 1000 over workersAt that time, the explosion takes place twice everyday, the first from 11am to 12am and the second from 5pm to 6pmIn 1999, all extraction and mining activities on the island is stoppedAquaculture farm

Station 6Kekek QuarryStopping of export of granites to Singapore by IndonesiaHousing and Development board decided to reuse this quarry to extract granites againLimited extraction will be carried out for companies to prepare themselves for the extraction activitiesThrough the preparation, the government will be able identify environmental problems faced when extractingStation 7Noordin BeachTo see the sea-viewToilet near the beachAct as a resting station for tourist before heading back to the resortEnd of TrialBack to ResortVia Green VehicleEnd at around 10.30amReferenceshttp://www.europeantravelway.com/etw/index.php?id=204http://wiki.answers.com/Q/What_are_the_advantages_of_beach_groynes http://uk.answers.yahoo.com/question/index?qid=20081122095135AAK5TiM http://www.travel-in-portugal.com/photos/img56.htm http://www.omafra.gov.on.ca/english/engineer/facts/87-040.htm http://chekjawa.nus.edu.sg/
