The children looked very excited, watching the small lights that lit up on the riverbank. Although only five lights, but it has given an interesting impression. The lights are lit using hydroelectric power plants, from waterwheels they make themselves. Of course it becomes something that is very meaningful in their thoughts and life knowledge. An experience that cannot be forgotten. That's why children need to gain valuable experience as children.
The night was getting late, but the children had not yet moved from the place. They still talk to their friends. Of course there are those who run around, some are sitting amazed on the riverbank watching the waterwheel that continues to spin. Some were standing under bamboo poles, watching the lights burn, sometimes looking very bright, but sometimes dimming. Of course, these intelligent children wonder why these lights can be flickering.
Melian sat next to Akbar, on a mat held by the children, on the riverbank near the waterwheel. Of course observe the mill along with the children who are busy playing.
"Sir ..., why do the lights sometimes light up brightly, but sometimes even dim?" suddenly a child asked Akbar who was sitting with Melian. Some kids are hanging out there. Of course I want to know.
"Why ...? Can anyone explain ...?" Akbar asked back.
Melian smiled at Akbar's words. Strange, the kids were told to think.
"Because of the wind, Brother .... Blows of wind kept swaying ..." replied one of the children.
"okay .... Someone has another opinion ...?" ask Akbar back.
"The electric current is unstable, brother .." replied the other child.
"Okay .., good .... Anyone want to answer again?" back Akbar gave another child a chance to answer.
But the children were all silent. No one else can argue. Understandably, children who do not have formal education, never enter school, never learn with teachers in the classroom. They only learn with willing volunteers based on their knowledge skills. But that is precisely the real practical science that exists in real life. Not the grandiose theories of the teachers.
"Come .... Has anyone ever played a battery flashlight?" ask Akabar to the children.
"There ...!" answer the children in unison.
"Well .., if the flashlight is still new, then the light will be bright. But if the battery has been a long time, then the light will dim. Because what? The ironclad is gone." Akbar said to the children.
"Rubber, Brother Akbar .... If the battery runs out, the lights don't want to go on." said the children.
"Nah .., same with those lights .... If the iron is less, then he will dim. But if the stun is strong, he will light up brightly." said Akbar while pointing to the lights hanging on the riverbank.
"But the lamp doesn't use a battery?" said one of the children.
"Lhah, the battery uses dynamo ..." said another.
"Ah .., I know .... If the dynamo rotates, the light will light up. But if the dynamics turn slowly, the lights will dim. Right, Brother ...?" said the kid who had the idea of making a waterwheel while studying with Melian this morning.
"Rubber .... Well, who's driving the dynamo?" akbar.
"Watermill ...!!" the kids are excited.
"Rubber .... If the waterwheel is spinning fast, then the electric current created is also large, because the dynamo rotates quickly. But if the flow of river water decreases, as a result of which the waterwheel will also slow down, the dynamics will rotate slowly. The electric current will also decrease. If the electric current decreases, the lights will dim." explained Akbar who is very contextual.
The children were satisfied with that explanation. Now they know a lot about hydropower. Of course, from their creation together. It was the most precious experience of his life.
Melian smiled looking at Akbar. He was amazed by Akbar's explanation that was very acceptable to children. Even Melian himself became familiar with the work system of hydroelectric power plants. And what is more proud is that they are able to make the equipment only from used items.
"Melian's cold, huh?" akbar asked as he looked at Melian whose hands had been pressed against his chest.
"Hmmm ...." Melian did not answer, only cleared her throat.
"This .... Wear my jacket ..." said Akbar who immediately took off his jacket, then put on Melian's body.
"Thank you, Akbar ..." said Melian after being covered in a jacket by Akbar. Of course with a sweet smile. Angannya immediately floated, again Melian imagined the goodness of Akbar would be given to him continuously.
"We go in, yuk .... The night air is not good for your health." Akbar invited Melian in.
"Later first .... I still want to watch the waterwheel ..." said Melian refused Akbar's invitation.
"What's fun ...?" ask Akbar.
"You're amazing, Akbar .... You are very clever .... You're a genius .... I'm proud of you." said Melian who praised Akbar.
"Ah .., great and clever Melian .... I'm ordinary, kok ..." said Akbar who is certainly humble.
"Look, Akbar .... You see that waterwheel .... Harmonization between the river and human life. Very beautiful and complementary .... I love a beautiful flowing life. The flow of water from the river that provides benefits for life, if we can manage it properly" Melian said while showing the continuous rotation of the mill following the push of the river's water flow.
Akbar was silent, not knowing with the words of philosophy expressed by Melian. Akbar is a technical person, the language is straightforward and direct at the core of the conversation. In stark contrast to the words of Melian who often uses tropes, of course people are confused to hear it. But Akbar still permeated the words Melian, as beautiful words from the poet.
"Yes, Mel ..." replied Akbar who could not express the beautiful words.
"Nature's symphony is beautiful .... But sometimes, human activities often disturb the harmony, so that it results in disturbing and even damaging the order of life" said Melian whose speech is increasingly difficult to understand by Akbar.
"Yes, Mel .... Sometimes interest is an excuse. Uh, Melian after graduation where are you going?" tanya Akbar who immediately switched the conversation bluntly. Akbar wants to talk ordinary.
"Not yet, Akbar .... At most return home." replied Melian.
"Go home ...? What do you want in the village?" sahut Akbar who wants to know.
"Well, is .... Girls want to do it again ..." replied Melian ceplas-ceplos.
"You want to marry ...?! Do you have a soul mate?" tanya Akbar wanted to know.
"Not .... Same with you, yeah .... Hehe ...." Melian was getting mocked, of course her hand while poking Akbar's cheek.
Instantly, Akbar's heart churned. Although it looks like a joke, but Akbar who has always admired Melian, when he heard Melian's words like that, wanted to feel like he immediately said "Yes, I'm willing". But Akbar is a good boy, who is unlikely to reply to Melian's words spontaneously. Unethical. But Akbar's feelings about Melian's expression remained well preserved in his heart.
"When does Melian want to go home?" ask Akbar.
"Actually while waiting for graduation, I want to go home first .... Already miss Mak-e and Pak-e .... I also miss Mas Irul .." replied Melian, who actually wanted to go home.
"Who is Mas Irul ...? He said Melian was an only child ..." asked Akbar who would want to know.
"You're jealous, yeah ...? Mas Irul was his employee crank, continued to be his employee Pak-e, then married Ms. Indra who .... But unfortunately, Ms. Indra died because of being hacked by criminals who robbed her shop .... " Said Melian who remembered the sad event.
"That's life. Everyone has predestined .... We cannot ask, nor can we refuse" said Akbar, whose hand slapped Melian's shoulder.
Melian's heart trembled, as soon as she felt the hand of the man she secretly admired stuck to her shoulder. Melian was still not moving. Can't even say what. But there is a strange feeling. Is this really the vibration of love?
The night is getting darker. The sound of a waterwheel played by the flow of Ciliwung River water, continues to flow causing shahdu gurgling. The small lights that are installed still change the power of the beam. Sometimes it is very bright, and sometimes it dims. Like human life, which sometimes shines brightly, but there are times when there is a decrease in spirit.
The place is quiet. The children went back in and slept in their own places. Akbar invites Melian to come back, enter the unique house. Melian's hand held Akbar's arm, definitely with a fluffy feeling. And certainly full of hope. That night, even though only dimly lit by the lights of bamboo poles, but the hearts of two people had begun to merge and blend.
