Bicycle and Sustainable Development Policy of Cuban Government

Riding bicycle is an urban recreational activity that I recommend to everybody who loves nature. In my previous post, I said that I ride my mountain bike in the afternoons as my way of maintaining my body in good health condition. The route that I choose is Kampung Ambon, Kwawi, Pasir Putih, Arowi, Bakaro. Actually this route is not suitable for my dirt jump bike - the Polygon Cozmic DX 2.0 whose gears are Shimano Alivio for mountain biking. The street along these places is smooth. After Pasir Putih beach, the number of motorized vehicles is fewer. The road between the Pasir Putih beach and Cape Bakaro is very good for cyclists who want to ride their bicycles, and at the same time enjoy cleaner air produced by trees that grow along the beach and the tropical rainforest of the region. Standing on the Pasir Putih beach, I can see the beautiful blue color of the sea in front of me and also the blue color of the Arfak mountains on the other side of the Dorey bay. Homes to various species of rainforest animals including the paradise birds. When I was still in elementary school, some cruise ships like to visit this small town. The ships brought tourists from Europe and the United States. But I've never seen Oasis of the Seas coming to this bay. It will be nice to see the largest and the most luxurious cruise ship in the world in this Dorey bay.  Oh, I was day dreaming, ha...ha.. ha....

Well, although bicycle is not considered as renewable energy resource, riding it is a way of reducing consumption of fossil fuel and at the same time fighting global warming through the reduction of CO2 gases emission.

Lesson Learned from Cuba

Several years a go I wrote an article about how Cuban government turned to renewable energy and urged people to ride bicycles when their country was suddenly entering economic crisis after the collapse of the Soviet Union. My article was published by Intisari - a national magazine in Indonesia. Cheap and subsidized fuel imported from Russia could not be enjoyed anymore.

To anticipate the energy crisis, Cuban government imported 1.5 million bicycles and tricycles from China. Domestic production of bicycles was increased to 100,000 units per year. At the same time, solar photovoltaic panels were introduced to provide electricity to homes, schools and health clinics throughout the country. In addition to solar power, Cuba built wind farms and installed hundreds of micro-hydro power and biogas plants that greatly reduced Cuba's dependency on fossil fuel. The policy of the Cuban government to tackle the economic crisis by relying on renewable energy attracted the attention of the UN. In 2001 Cuba received the UN's Global 500 award. Now Cuba is seen as a model for many countries around the world that want to develop their renewable energies. Engineers from Cuba help Bolivia, Honduras, Lesotho, Mali, Nigeria, South Africa and Venezuela in developing their renewable energy sectors.

Dutch Cycling Culture

Besides learning from Cuba, we - Indonesian people - can look at the Netherlands as a good example for renewable energy application. Dutch people ride bicycles to work. Install photovoltaic panels at the roofs of their homes and build wind farms at sea.  Cycling is not only a hobby but has been part of their lifestyle or culture. Dutch were the ones who introduced cycling to Indonesian people during the colonial period. Therefore, we can learn from them if we are serious in developing our country through sustainable methods.

Cycling to Pasir Putih Beach

After writing a number of articles about Oasis of the Seas, the largest and most modern cruise ship in the world, now I am writing about my hobby again which is mountain biking. Although the keyword of Oasis of the Seas is now getting higher impression in my blog, I feel that I should write something that really reflects my daily activities. I have been riding bicycle since I was in elementary school. I didn't know why I was very fond of cycling around my neighborhood with my BMX at that time but I really enjoyed the surrounding view of the Manokwari town and the Arfak mountains while riding along the hills of Panorama street. Now my bicycle is not a BMX anymore but a Dirt Jump Mountain Bike Polygon Cosmic DX 2.0. I started riding this bike on the first week of December 2010.

I usually ride my bicycle in the afternoons along the Brawijaya street (formerly known as Panoramaweg during the Dutch time) to Kwawi, Pasir Putih beach - the most favorite white sandy beach both for town dwellers and finally tourists, Pasirido, and finally Bakaro beach. It takes around two hours for me to enjoy the beautiful coastal region of Manokwari city that is now developing very fast. I am often accompanied by my friend Peddy Tangguni. He was my classmate when we were in high school. He rides his United mountain bike.

When I began riding my mountain bike again early this month, I was not familiar with shifting gears from 8 to 1 for the rear ones and from 3 to 1 for the front gears particularly when climbing a slope. After using the bicycle for several times now I know that I need to use gear 1 (front and rear) while on a steep slope; and Gear 3 (front) and Gear 8 (rear) on a flat road or going down a slope. The gears of my mountain bike are Shimano Alivio. Shimano is a leading manufacturer of bicycle components from Japan.  The brake is manufactured by Tektro - I think its a Taiwanese company. The bike frame is made of aluminum. Polygon calls it Alx 6061. It is a light metal compound that is strong enough for mountain bike application. It's interesting to see that the front suspension fork of the bike is Suntour Duro DJD.

I start riding the bike at 4.30 p.m and return home at 6.30. It is nearly dark when I get back home. Along the road, I often see children riding their BMX bicycles. The second picture above shows how Peddy - my friend, and some Papuan children were riding bicycles near Pasirido.

Cycling is good for our environment. People who ride bicycles to their workplaces have helped reduce the CO2 emission. CO2 gases are the cause of acid rains that are harmful to the green leaves and trees of the tropical rainforest. By riding bicycle we reduce the air pollution of our city.

Cycling is also good for our health but I hardly ever see adults in Manokwari city ride bicycles in the afternoons. I hope that through my regular exercise riding this mountain bike, more and more people will be interested in joining me and my friend in the coming months of 2011. Lets's ride bicycles, let's save energy, let's protect our tropical rainforest and let's fight global warming.

Oasis of the Seas - Cruise Ship or Passenger Ship?

Last night I opened my webmaster.google.com account and found that the impression of keywords Oasis of the Seas is rising significantly. This is the name of the largest and the most modern cruise ship in the world. This motor vessel can carry around 6,000 passengers. She travels to the Caribbean islands.

Passenger Ship

As a traveler, I used to go by passenger ships around a number of islands in Indonesia. Indonesia is the largest tropical archipelago in the world. Ships of any kinds or types play very important roles in transporting people and goods throughout the country.

The big ships that I used to travel around with were the ones operated by PELNI - a state owned passenger line in Indonesia. The first group of passenger ships that were imported from Germany were MV Rinjani, MV Kerinci, MV. Kambuna and MV Umsini. MV stands for Motor Ship. The carrying capacity of each of these ships is around 2,000. During holiday seasons, PELNI allowed the ships to carry up to 2,500 people on board. The main propulsion unit is diesel engine. The diesel engine is used to turn the marine screw propeller, most often, the controllable pitch propeller (CPP). Electrical power for supplying the electricity needs of the ship is obtained from a number of auxiliary engines both installed in the engine room near the main engine or on the upper deck of the ship.

The difference between Cruise Ships and Passenger Ships

Passenger ships and cruise ships are similar but not the same. Both of them carry passengers but their purpose are different. Passenger ships like MV. Dobonsolo, KM Dorolonda and KM Nggapulu in Indonesia go from one port to another tranporting people mostly on one trip. But for cruise ships such as the Oasis of the Seas and the Allure of the Seas. The cruise ships themselves have become the destination of holiday. The passengers usually buy round trip tickets meaning that they will finally return to the port where they first begin the ocean tour. Most of the passengers of cruise ships Oasis of the Seas and Allure of the Seas who go to the Caribbean islands will return to, for example Miami, after they finish their tour. Oasis of the Seas Rooms are bigger and more luxurious than most of the rooms in passenger ships operated by PELNI.

Purpose of Sea Voyage and Facilities Inside

Because the purpose of traveling is different from cruising, the facilities that we will find in MV Nggapulu will be different from MV Oasis of the Seas. The Carribean sea may have been saturated with cruise ships but the Indonesian sea is not. In addition, cruise ships may be too expensive for the working class Indonesian people to travel around. There are bedrooms in both of the ships but Oasis of the Seas has more space for recreation. This cruise ship has swimming pools, game center, park, shopping center that we cannot find in most of the passenger ships that operate in Indonesian waters. The purpose of the trip determines how naval architects design the ship.

Design Approach 

Ship design is the product of art and science. Architects who design modern cruise and passenger ships now have a lot of software which they can use. Different from home architects who usually use BIM software such as Archicad and Revit, Naval Architects can now use Maxsurf, Delftship, Rhino Marine or Foran to outline design concepts in their mind into a beautiful cruise ship. They may use Archicad but it is only limited to the interior design projects of the ship. BIM modeling software such as Archicad does not have stability, propulsion, and strength calculation capabilities that most naval architects need to design a ship or other floating structures.

So, if you are planning to take a spring vacation in tropical islands in Indonesia by visiting islands of this largest achipelago by ship, don't expect to experience luxurious sea voyage in PELNI ships. The facilities of the PELNI passenger ships are quite good but not luxurious. The price is much cheaper mostly less than 100 US dollars for economy class per trip. If you plan to cross the islands from Sabang to Merauke by buying first class ticket, you will spend less than 1,000 US dollars (including meals which are served by the ship). The cross country sea voyage in Indonesia will take your time around 2 weeks.
