Story Telling - Telaga Warna

Long, long ago there was a kingdom in West Java. The kingdom was ruled by a king. People called their king His Majesty Prabu. Prabu was a kind and wise king. No wonder if that country was prosperous. There’s no hunger in this kingdom.

It was a very happy condition. But it was a pity that Prabu and his queen hadn’t got any children. It made the royal couple very, very sad. Some old men and women who was respected by Prabu suggested the king to adopt a child. But Prabu and the queen didn’t agree. “No, thank you. But for us, our own daughter or son is better than adopted children.”

The queen was very sad. She often cried. That was why Prabu decided to go. He went to the jungle. There he prayed to God. Everyday he begged for a child. His dream came true. A few months later, the queen got pregnant. All people in the kingdom felt happy. They sent many presents to the palace to express their happiness.

Nine months later a princess was born. People sent their presents again as a gift to a little princess. This baby grew as a beautiful teenager then.

Prabu and Queen loved their daughter so much. They gave what ever she wanted. It made Princess a very spoiled girl. When her wish couldn’t be realized, she became very angry. She even said bad things often. A true princess wouldn’t do that. Even though the princess behaved badly, her parents loved her, so did the people in that kingdom.

Day by day, the princess grew more beautiful. No girls could compare with her. In a few days, Princess would be 17 years old. So, people of that kingdom went to palace. They brought many presents for her. Their presents gift were very beautiful. Prabu collected the presents. There were really many presents. Then Prabu stored them in a building. Some times he could take them to give to his people.

Prabu only took some gold and jewels. Then she brought them to the goldsmith. “Please make a beautiful necklace for my daughter,” said Prabu. “My pleasure, Your Majesty,” the goldsmith replied. The goldsmith worked with all his heart and his ability. He wanted to create the most beautiful necklace in the world because he loved his princess.
The birthday came. People gathered in the palace field. When Prabu and queen appeared, people welcomed them happily. Prabu and his wife waved to their beloved people.

Cheers were louder and louder when the princess appeared with her fabulous pretty face. Everybody admired her beauty. Prabu got up from his chair. A lady gave him a small and glamorous pillow. A wonderful necklace was on it. Prabu took that necklace. “My beloved daughter, today I give this necklace to you. This necklace is a gift from people in this country. They love you so much. They presented it for you to express their happiness, because you have growing to a woman. Please, wear this necklace,” said Prabu.

Princess accepted the necklace. She looked at the necklace in a glance. “I don’t want to accept it! It’s ugly!” shouted the princess. Then she threw the necklace. The beautiful necklace was broken. The gold and jewels were spread out on the floor

Everybody couldn’t say anything. They never thought that their beloved princess would do that cruel thing. Nobody spoke. In their silence people heard the queen crying. Every woman felt sad and began crying too. Then everybody was crying.

Then there was a miracle. Earth was crying. Suddenly, from the under ground, a spring emerged. It made a pool of water. The palace was getting full. Soon the place became a big lake. The lake sank all of the kingdom.

Nowadays the water on that lake is not as full as before. There is only a small lake now. People called the lake “Talaga Warna”. It is mean “Lake of Colour”. It’s located in Puncak, West Java. On a bright day, the lake is full of colour. So beautiful and amazing. These colors come from shadows of forest, plants, flowers, and sky around the lake. But some people said that the colours are from the princess’s necklace, which spreads at the bottom of the lake.

Story Telling - Timun Emas

Long time ago in the island of Java, Indonesia, lived a couple of farmer.  They had married for some years but they had no children.  So they prayed to a monster called Buta Ijo to give them children.  Buta Ijo was a ferocious and powerful monster.  He granted their wish on one condition.  When their children had grown up, they had to sacrifice them to Buta Ijo.  He liked eating fresh meat of human being.  The farmers agreed to his condition.  Several months later the wife was pregnant.

She gave birth to a beautiful baby girl.  They named her Timun Emas.  The farmers were happy.  Timun Emas was very healthy and a very smart girl.  She was also very diligent. When she was a teenager Buta Ijo came to their house.  Timun Emas was frightened so she ran away to hide.  The farmers then told Buta Ijo that Timun Emas was still a child.  They asked him to postpone.  Buta Ijo agreed.  He promised to come again.  The following year Buta Ijo came again.  But again and again their parents said that Timun Emas was still a child. 

When the third time Buta Ijo came their parents had prepared something for him.  They gave Timun Emas several bamboo needles, seeds of cucumber, dressing and salt. 

‘Timun, take these things’

‘What are these things?’

‘These are your weapons.  Buta Ijo will chase you.  He will eat you alive.  So run as fast as you can.  And if he will catch you spread this to the ground.  Now go!’

Timun Emas was scared so she ran as quickly as she could.  When Buta Ijo arrived she was far from home.  He was very angry when he realized that his prey had left.  So he ran to chase her.  He had a sharp nose so he knew what direction his prey ran. 

Timun Emas was just a girl while Buta Ijo was a monster so he could easily catch her up.  When he was just several steps behind Timun Emas quickly spread the seeds of cucumber.  In seconds they turned into many vines of cucumber.  The exhausted Buta Ijo was very thirsty so he grabbed and ate them.  When Buta Ijo was busy eating cucumber Timun Emas could run away.

But soon Buta Ijo realized and started running again.  When he was just several steps behind Timun Emas threw her bamboo needles.   Soon they turned into dense bamboo trees. Buta Ijo found it hard to pass.  It took him some time to break the dense bamboo forest.  Meanwhile Timun Emas could run farther.

Buta Ijo chased her again.  When he almost catch her again and again Timun Emas threw her dressing.  This time it turned into a lake.  Buta Ijo was busy to save himself so Timun Emas ran way.  But Buta Ijo could overcome it and continued chasing her.

Finally when Timun Emas was almost caught she threw her salt.  Soon the land where Buta Ijo stood turned into ocean.  Buta Ijo was drowned and died instantly. 

Timun Emas was thankful to god and came back to her home.

Salah Paham Karena Bahasa Inggris

Benarkah bahasa sumber kesalahpahaman? Yah, mungkin benar atau mungkin salah. Jika benar memang banyak contohnya, misalnya orang batak yang biasa berbicara dengan nada tinggi menanyakan asal orang jawa, “Hey anak mana kau?”, orang jawa yang konon berwatak lembut dan halus (kata siapa yah) bisa saja menganggap bahwa orang batak tersebut sedang mengancam karena keberadaan orang jawa tersebut, padahal mungkin orang batak tadi hanya menanyakan asal orang jawa tersebut karena sering melihat orang jawa tadi namun belum mengenalnya.

Jika salah juga lebih banyak lagi contohnya, misal saya bergadang sampai pagi hingga bangun siang hari sampai-sampai bos saya ngomel-ngomel akibat saya  tidak masuk kerja, apa saya harus mengatakan bos saya salah paham akibat saya tidak izin dulu atau bos saya salah paham akibat saya tidak masuk kerja (wah bingung ya, iya saya juga bingung kenapa contohnya ngawur kaya gini ya?) begini saja, biar enak yah mungkin sobat-sobit saja yang berpengalaman tentang kesalahpahaman bisa menjelaskannya, anda kan lebih tahu tentang pengalaman kesalahpahaman yang pernah anda rasakan sendiri yang bukan akibat kesalahan bahasa.

Disini saya cuma akan menuliskan sebuah kutipan tentang bahasa dari Antoine de Saint-Exupery, seorang penulis asal Prancis yang mendunia karena karyanya yang berjudul Le Petit Prince (Sang Pangeran Cilik). Ini dia kutipan Antonie:

“Language is the source of misunderstandings.”

Mudah diingat bukan, jika sobat-sobit bertengkar dengan pacar, saudara, istri, suami, atau lebih parah lagi dengan orang tua akibat kurang komunikasi, membentak, menyindir, mengkritik, protes, demo, salah ucap, ataupun hal-hal lain yang berhubungan dengan bahasa, mungkin alangkah baiknya jika anda merenung sejenak sambil berkata lirih dalam hati, “That’s true what Antonie said that Language is the source of misunderstanding.”

Namun yang perlu diingat, meskipun mungkin bahasa adalah sumber kesalahpahaman, Bahasa juga bisa berfungsi sebagai sumber pemecah berbagai permasalahan. Lihat saja perundingan-perundingan menjelang dan sesudah kemerdekaan RI untuk merebut dan mempertahankan kemerdekaan Negara tercinta ini, atau sebut saja teks proklamasi yang digaungkan Soekarno pada 17 Agustus tahun 45, semuanya mengandalkan kemampuan berbahasa. Saya tidak bermaksud menyepelekan jasa-jasa pahlawan kita, hanya saja saya tekankan bahwa bahasa adalah hal yang sangat penting untuk dipelajari sehingga kita bisa menghindari kesalahpaman dengan menggunakan bahasa pula.

Maaf, jika ada kesalahpahaman akibat tulisan yang saya publikasikan ini, saya hanya sekedar berceloteh sedikit, tidak ada maksud untuk menguak sebuah kontroversi baru. That’s just what I mean bro..

Contoh Story telling pendek

The Lonely Landy

One day, there was a porcupine named Landy. He was lonely. No one wanted to play with him, because they were afraid of his spike.

“Dear Landy. We don’t want to play with you because your spikes are too sharp. We don’t want you to hurts us,” said Cici the rabbit one day.

“Cici is right, Landy. It is not because you’re bad or rude to us, no, Landy. Just because of your spikes. They will stab us if we close to you,” said Tito the rooster.

Landy felt lonely. Landy spent most of the time day dreaming at the river bank, “I would be happy if there were no spikes on my body.”

Suddenly, Kuku the turtle appeared from the river. He came to Landy and said, “Landy, what are you thinking of ?”

“Oh, nothing,” Landy replied.

“Don’t lie to me, Landy! Who knows I can help you,” said Kuku wisely. Then he sat beside Landy. He wasn’t afraid of Landy’s spikes.

Shortly, Landy told his problem. Kuku nodded his head. He said, “Poor you. But it isn’t your fault. I know, your spikes are very useful and helpful for you. They will realize it someday. Trust me!”

“Thanks, Kuku. You are my best friend.”

One day, Koko the frog held his birthday party. He invited all his friends, including Landy. But he decided not to come. He didn’t want to mess up the party.

“I’ll come with you Landy. I’ll tell everyone that you’re harmless,” said Kuku. Finally Landy attended the party. Everyone enjoyed it.

Suddenly Tito screamed, “Help….help.…! The evil wolf is coming. Save yourself!” Then, everyone saved their lives, except Kuku and landy. Kuku pulled his head and his leg into his shell. And Landy rolled his body into a ball.

Unintentionally, the evil wolf touched Landy. Of course, the spike pricked him. He screamed, “Ouch!” Since his foot was bleeding, he didn’t chase Landy’s friends any longer. Then, he ran away.

“Horray….horray….! Long live Landy! He saved our lives,” said Cici and her friends. They thanked him from then on. Landy wasn’t lonely anymore.

Moral  value  :

We should not underestimate someone’s bad physical appearance.
