On Wednesday, we went to visit the Evergreen and Hollywood Veggie. The purpose of the visit was to find a problem, which will have to solve. After looking for information in the Evergreen, we got a problem. The problem was about the lighting system, and emergency ropes.

In the second week we were in Singapore. We’re doing some kind of research to create a lighting system with Raspberry-Pi. After discussion with the group, we agreed to make the Automatic Lamp System. This system uses the principle sum. When people go into a room, the sensor will count +1, and if there are people out of the room, then the sensor will count -1. As long as the value of the sum is greater than 0, then the room lights will turn on.

We decided to make an Automatic Light System simulator. Once we agreed with our project, we bought equipment and components we needed. After getting the materials we needed, we started working on our project. We create a program for the sensor, arrange sensors on the doors. Sensors made of two pairs of infrared transmitter receiver.

Sensors are arranged side by side, so that when someone comes from the right side to the left past the sensor, then +1, if from the reverse side, then -1. After successfully with sensors, we try to add other features to press the remote as an emergency ropes replacement. Initially we did not know what to use. Then Mr. Jason bought us a remote control relay.

This is Radio Frequency Remote, so that it can be used even obstructed by the wall. We have not used this remote module, so we had to try it. After successfully find a way of operation, we immediately add it to our project. How do remote module work is to emit radio signals at a certain frequency, then the signal received by the receiver, then the signal is converted into a logic 0 or 1 (low or high). The logic then used to drive a relay. So that the movement of this relay, then we use to turn on the alarm bell.

We also added a master switch to turn off all systems, especially when the user wants to sleep. In addition, the system will turn off automatically when no one in the house.

In the first week in Singapore after my friends and I landed at Changi airport. We were greeted by the students of RP. They welcomed us with a good and friendly. After that we were invited to go to the RP to where we were staying. On the way there, I see a much different city atmosphere with Indonesia. A lot of development on either side of the road, and also the environment is clean.

On the first day, we were introduced to the rooms and the buildings in RP. The environment around the campus are very clean, a field with green grass cared, amazed me. Also a clean campus cafeteria, food hygiene is guaranteed, and the cafeteria system is running well. Such as queue when ordering food, and return the plates to wash after eating, and also remove the bottle into the trash. Everyone seemed to do these rules voluntarily and without coercion.

The next day, we were invited to go to the Evergreen. Evergreen is a place for people who are elderly. We look at the state of the people there. They live in a building similar to the apartment. Where to stay as this makes them come alive as individuals. and most of them live alone. Many incidents of people dying who to rot for weeks.
After that we were invited to Bollywood Veggie. This place looks like a museum of plants in Singapore. Many plant species are preserved there. Most of the plants we have encountered in indonesia.

On Saturday, we invited our new friends from RP to shop for our daily needs in Causeway Point. On the way to the causeway, there is one thing that I never met. All cars turned onto another road immediately stop when we cross into to the crossing. This is very different from Indonesia, because pedestrians have to wait hundreds of motorcycles and cars to turn. So few people are willing to walk.

On Sunday, we went to the USS. We go along with our new friends from RP. We came there around 10 o’clock. All the rides we visited treated well, and visitor safety is guaranteed. We have fun together there. We going back home when the USS almost closed, around 6pm.

Of all those days, we are always accompanied by our new friends from Singapore. They always faithful drove us everywhere, introducing us to the places and buildings in Singapore. They are extraordinary friends.

Of all these visits, many things I learned. Starting from the environment, the queuing system, how to use the elevators, pedestrian rights, and safety. All of that makes Singapore become a fine city. All nice and orderly arranged. However, many residents of the city becomes like a living individual. Such as evergreen, neighborliness life is less. Many of those who live without recognizing its neighbors. Whatever the cause, but I think if this kind of life is not changed, the next generation will be the generation of robots. A generation that will do something only if there is a command.
