Belimbing Wuluh sebagai Sumber Energi Alternatif

Energi adalah suatu hal yang tak dapat lepas dari kehidupan sehari-hari. Dari hari ke hari kebutuhan akan energi semakin meningkat, peningkatan ini dipengaruhi oleh banyak faktor yaitu, gaya hidup, kepuasan manusia yang tak ada hentinya, semakin majunya peradaban manusia dan lain-lain. Energi berdasarkan sumbernya dibedakan atas 2 yaitu energi yang terbarukan dan yang tidak terbarukan. Energi yang sering digunakan dalam kehidupan sehari-hari adalah energi yang tidak terbarukan. Dengan demikian energi tersebut semakin lama akan semakin berkurang. Contoh dari energi yang tak terbarukan adalah minyak bumi yang berasal dari fosil-fosil yang telah berjuta-juta tahun berada di dalam perut bumi.

Meihat hal tersebut, maka dibutuhkan suatu energi yang terbarukan sehingga dapat mengurangi penggunaan energi yang tak terbarukan seperti minyak bumi. Melihat potensi dari belimbing wuluh yang tumbuh subur di Indonesia maka penulis ingin memaparkan penggunaan dari belimbing wuluh sebagai medai sumber energi alternatif.

Belimbing wuluh yang dalam bahasa latin dikenal dengan nama avverhoa bilimbi adalah tanaman asli Amerika yang tumbuh subur di daerah yang banyak mendapat sinar matahari langsung tetapi cukup kelembaban udaranya. Belimbing Wuluh merupakan tumbuhan berbatang keras yang memiliki ketinggian mencapai 11 m. Biasanya ditanam di tempat yang cukup mendapatkan sinar matahari. Batangnya keras dan tidak bercabang banyak. Buahnya berwarna hijau muda, berbentuk lonjong sebesar ibu jari dan rasanya asam. Buahnya sering dipakai untuk memasak sehingga sering disebut juga belimbing sayur ataupun untuk membersihkan noda yang menempel pada kain seperti kuningan dan tembaga. Daunnya yang kecil berhadap-hadapan. Bunganya berbentuk bintang dan berwarna merah muda keunguan. Gambar dibawah ini menunjukkan belimbing wuluh.

Kandungan dan Khasiat Belimbing Wuluh: Belimbing wuluh bermanfaat sebagai anti radang karena mengandung flavon. Selain itu, kaliumnya melancarkan keluarnya air seni (diuretik) sehingga dapat menurunkan tekanan darah. Belimbing wuluh juga mampu mengeluarkan dahak dan menurunkan panas. Buahnya mengandung zat: asam-kalium-akolat. Ini adalah salah satu kegunaan dari belimbing wuluh diluar sebagai sumber energi alternatif.

Belimbing wuluh yang tumbuh subur di pekarangan rumah, dapat disulap menjadi zat pengurai yang mampu menghasilkan tenaga listrik alternatif, di tengah keluhan warga akan kenaikan tarif dasar listrik (TDL). Untuk menciptakan energi listrik tersebut, awalnya belimbing yang biasa digunakan sebagai sayuran ini dihaluskan untuk diambil airnya. Selanjutnya, dengan menggunakan media tanah yang ditaruh dalam gelas bekas air mineral ini, air belimbing ini disuntikan secukupnya.

Selanjutnya, masing masing gelas berisi tanah bercampur sari air belimbing ini dihubungkan dengan rangkaian kawat lempengan tembaga dan seng, guna mengalirkan arus listrik. Hasilnya, energi listrikpun tercipta dengan tegangan yang lumayan, yakni hingga mencapai 5 volt, cukup untuk menghidupkan lampu penerangan. Tegangan yang dihasilkan ini juga lebih besar dari tegangan satu buah batu baterai.

Alat dan Bahan yang diperlukan:
1) Belimbing Wuluh
2) Blender
3) Gelas plastic
4) Tanah
5) Air
6) Lempeng tembaga (sebagai elektroda positif)
7) Lempeng seng (sebagai elektroda negatif)
8) Kabel

Cara pembuatan Energi Alternatif dari Blimbing Wuluh:
1) Blender blimbing wuluh sampe halus (jadi jus belimbing wuluh; masak jus apel) sehingga diperoleh cairan yang menyerupai air (tanpa serabut/ampas).
2) Siapkan gelas-gelas plastik dan diisi dengan tanah liat (bukan tanah berpasir ataupun yang mengandung sampah). Gelas tersebut dapat berasala dari sisa minuman air mineral.
3) Masukan jus blimbing wuluh tersebut ke dalam gelas-gelas plastik yang sudah diisi tanah.

4) Susun berderet gelas-gelas yang sudah diisi tanah dan jus blimbing wuluh

Gambar 3. Susunan gelas-gelas yang sudah diisi tanah dan jus blimbing wuluh serta telah dimasukkan elektroda


5) Buat rangkaian elektroda dengan menyambungkan antara lempeng tembaga dan lempeng seng menggunakan kabel (kira-kira dengan kabel masing-masing 15cm)
6) Susun rangkaian elektroda tersebut ke dalam gelas-gelas tanah yang telah disiapkan sebelumnya, dengan susunan lempeng tembaga-lempeng seng-lempeng tembaga dan begitu seterusnya, jadi satu gelas akan berisi susunan satu lempeng tembaga dan satu lempeng seng dari rangkaian elektroda yang berbeda
7) Siapkan dua rangkaian elektroda dengan kabel yang lebih panjang dan hanya menggunakan satu lempeng saja, satu tembaga dan satu seng. Untuk gelas terluar (gelas pertama dan terakhir yang hanya memiliki satu lempeng: gelas pertama lempeng tembaga dan gelas terakhir lempeng seng) disambungkan dengan rangkaian elektroda baru ini. Gelas pertama dengan yang rangkaian seng, gelas terakhir disambungkan dengan rangkaian tembaga. Ujung dari dua kabel rangkaian terakhir inilah yang akan disambungkan dengan lampu yang akan dinyalakan.

<p style="text-indent:2em; padding:0px; margin:0px;line-height:240%;">Air Jordan shoes have a plain and simple structure based on advanced technology, which makes it possible to get high performance out of each and every shoe. Most of the nike Jordan shoes have been designed for basketball players although its popularity can be seen outside the basketball courts as well. Promoted by Michael Jordan, these shoes come with the ¡°Jumpman¡± logo and are inspired from real life events, people, and objects.

However, why tops their email list most for the creation of this sneaker is obvious. The celebration type of shoe marks the 25th year of the Anniversary of the Air Jordan line usually. What also makes this shoe stay ahead of the other Nike Jordan basketball signature shoes is the fact that this shoe represents the future of the Jordan brand in the world.Each new shoe design that Nike Jordan range pops up with is definitely a product that's more innovative and much better than before. The reason being Air Jordan is a brand. That's a firm believer in incorporating the element of imagination into every shoe. This is because they want to develop the best product throughout for the eager consumer to have. When there is imagination. There are no limits on where the creation of a new Jordan sneaker can go from here.The Nike Jordan 2010 is not just a celebration kind of shoe. It's also a lot more. What makes this latest Jordan shoe stick out specifically is always that it has a look out of performance like no other basketball shoe out there. The thermoplastic urethane window or (TPU) is truly what Michael Jordan conceived as the way for him to have ability to look out of each of his opponents out on the basketball court. The noted designers who helped Michael Jordan bring this shoe to life from Jordan personal interpretation were not one other than Tinker Hatfield and Mark Smith. This latest shoe, which was released officially on February 13, 2010, is a fine illustration of what future shoes will be as part of the famous Jordan brand.There are other facets of the Air Michael Jordan basketball shoes. That sets it apart from the other Jordan members from the Nike Air Jordan brand label. This very professional basketball shoe is very lightweight and provide a lot of support from a natural movement perspective. Another facet of this shoe is that it has a toe construction. That's both layered and which has a forefoot support cover that is completely independent in addition. This special technique allows a person to be more agile when moving and does not restrict the foot flexibility and movement too.</p><p style="text-indent:2em; padding:0px; margin:0px;line-height:240%;">When started the 1980s the popularity reached Nike Dunks sneakers brand. For the players it was urgent to secure their muscles when they trained on the court, so the company introduced using canvas together with high shoe tops. Rubber sole was the second reason for over six hundred million pairs to be sold.Time passed and the basketball sneakers tendencies developed. Nike Dunks are made of leather now, not of that time canvas. Soles are made with special cushioning layer the way that you are comfortable to bounce, run and look. That high-topped design created by Nike Dunks is by now preferred in basketball shoes design. Canvas is still not forgotten. It¡¯s turning fashionable to return to those retro origins.Maybe those famous basketball stars do not wear canvas shoes. But lots of them cooperate with the producers. Have a look! You will see many students, skaters, different people who love both style and comfort of wearing wonderful basketball sneakers. Nike Dunks first model is still sold much more successfully than even Nike's Air Jordan Shoes. They were previously affordable just in black, but today you may choose any color you like. About 30 thousand pairs are bought each week. Considering the competition the result is really good.A sportsman these days may buy any of numerous basketball sneakers manufacturers functioning. But the logo of Air Jordan Shoes is anyway the most familiar to each of us. The sneakers appeared to be popular just in 1985 despite that the agreement with the basketball star M. Jordan, after whom the shoes were named, was signed in 1984. Jordan¡¯s silhouette was elegantly inquired into the logo on the shoes, where he was performing a slam dunk. The sales of the model were just great that time. 21 new designs have been made with this model since the day of it¡¯s appearance, so the first variations may be found only in some fans¡¯ collections.Adidas was certainly never worse in basketball sneakers production. Having designed their Shoe Laces basketball shoes, famous as the T-Mac in 2004 the company brought a new trend into the industry of basketball shoes. There are many various firms that make high-quality shoes, such as Asics, Reebok or New Balance. Their sneakers may be seen on many basketball players.But they are nevertheless different from Nike. For the assurance, constant comfort and perfect bouncing wear Nike Dunks were long ago preferred by skaters, so Nike's basketball shoe line is really popular in this scene. Nike SB Dunk was the tribute to this movement after a period of time. The model was made just for skaters. The shoe is completed with features like extra-padded "puffy tongue" and Nike¡¯s special Zoom Air insole. That all makes it perfect for skaters. Then the collectors of shoes got the new thing to wish. SB Dunk was easily seen on the streets. These days Nike is not about to finish the fashionable trend. It works with lots of talented designers in order to develop Dunks and work out masterpiece models.The advised cost of SB Dunks in the stores is not really high, about from 65 to 99 dollars. But thanks to great popularity of the brand the stores tend to take profits of the demand on the model by changing prices. This is a common matter especially when the sneakers are discussed in the network.</p><p style="text-indent:2em; padding:0px; margin:0px;line-height:240%;">I just got a new pair of Nike Air Force One shoes, and I am on cloud number nine. My custom Nike Air Force Ones are the coolest thing that I have seen in years. These ones are a special St. Patrick's Day addition, done in bright green and white. Very retro and stylish. I have originally intended save my Nike Air Force One shoes solely for playing basketball, but the thing is, I just can not take them off of my feet. Everyone who sees it casts me a look of envy, because they know that I've got the cash flow to buy the nice threads. Some people say it¡¯s shallow, but I ask you, is it shallow to want other people to look up to you because of your nice clothes. Of course it isn't.Inevitably, there are some kids who don¡¯t surrender their hearts and souls to my Nike Air Force One shoes, but they are strictly losers. There's this one hippy kid who always is telling some story to denounce my swoosh, because he says that it promotes sweatshops, whatever that means, but I can tell that he is just plain jealous of my Air Force One sneakers. Come one, look at what he's got. He¡¯s perpetually showing off his ¡°black spot¡± shoes as if the black spot is something special. Yeah, whatever. Black spot is not the swish. And that swish is just what I have got on my Nike Air Force One shoes.But it is not all about the style, or even the performance of Nike Air Force One shoes, although that is part of the attraction, for me. I have never felt more comfortable in my game than since I bought my Air Force 1 shoes. They give me more confidence and athletic freedom, and more game all around than I have ever had before. Not like the black spot kid who never even touches the ball.But really, what I like about my Nike Air Force One shoes is just being myself. Because, you see, that is really what it is all about. And it is easy to be myself in my Nike Air Force One shoes, because they are exactly what I am all about. But you try to tell that to one of those dorky kids, always pretending that they¡¯re doing great things by saving the environment and foreign workers and crud like that. They are so busy trying to impress others that they never get it. I never waste my time with them. I¡¯ve got my Nike Air Force One shoes for company.</p><p style="text-indent:2em; padding:0px; margin:0px;line-height:240%;">There are various shoes for athletics that someone may pick from at this time. Someone can choose one because of a sport they play or just for fashion. A top pick for someone that plays basketball would be the Nike basketball shoes.The company was first created in 1964. When it was first founded its name was Blue Ribbon Sports. After a short time the company changed its name to Nike after a dream about the Greek Goddess of victory by that name. A short time after that the company unveiled the swoosh as their company emblem.The early sneakers were made with a sole that featured Air Sole units. These soles were made with bags of pressurized gas in them so they would compress at impact then spring back to size. This technology was brought to them by a former aerospace engineer.In a turning point for the company Michael Jordan was signed to endorse shoes in 1984. He had just entered the NBA from the University of North Carolina and was just beginning to make a name for himself in the NBA and in endorsing products. His shoe line, the Air Jordan's, were released the next year.Michael's Air Jordan line brought the basketball spotlight to the company. The shoes were not allowed to be worn during a game because they did not meet the league dress code at that time. Even though he was warned of this Michael still wore the shoes and received fines for each time he did. The fines worked as an advertisement for Nike and Michael because it consistently put the Air Jordan's in the news for everyone to see.In 1986 Michael won the slam dunk contest and became interested in playing a bigger role in the designing of the Air Jordan line. Because of this the line started being manufactured with materials that were lighter and in a three-quarter cut shoe instead of a high top. The Air Jordan line sales elevated to all time highs as it was now not only endorsed by one of the top stars in the NBA but also partially designed by him. That extra feature helped separate the line from other products as it carried a special Michael Jordan touch to it.The Air Jordan line success opened the door for Nike to sign many other NBA players to endorse shoe lines. Kevin Durant, Vince Carter, LeBron James, Kobe Bryant, Dwayne Wade, Carmelo Anthony, Chris Paul, and many other NBA players have Nike shoe lines at this time. In the same way that Michael helped design his Air Jordan's many of these other players also play an integral part in the designs of their lines.With the firm backing of the top players in the NBA, both past and present, Nike basketball shoes are a good choice if someone is looking for shoes. The lines are normally designed in part by the player themselves to add a special signature touch to them. Because of that added attention the choices are as much as a fashion statement as they are basketball shoes.</p><p style="text-indent:2em; padding:0px; margin:0px;line-height:240%;">Nike has just launched the newest Air Jordan in 2011, the 26th version in Air Jordan shoes series, though we don't know for sure if the number is correct. Besides its classic 3 colorways, this new version has a special limited edition: the Year of the Rabbit Air Jordan -- 2011 is Rabbit Year in Chinese Lunar Year. It might seem strange for a basketball shoe named like this, but obviously the decision is to coincide with a momentous year for Michael Jordan himself -- Mr. Jordan was born in the year of the rabbit, 1963. As he turns to be 48 years old today, he enters the year of birth for the 4th time with his shoe slathered in Chinese symbolism. The Rabbit Year Air Jordan shoebox is designed to match the red envelopes, which is used to give lucky money at Chinese Lunar New Year, in red and gold with iconic geometric designs and Chinese characters, revolving around the Jumpman silhouette logo. The shoe itself bears a white/metallic gold/varsity red/wolf grey colorway, at least two of them are popular colors in China, and it also matches well with Chinese national team uniform, Chicago Bulls uniform. The special edition Jordan shoe also features an insole reads "Brooklyn", which is the New York borough where Mr. Jordan was born and also home to many Chinese people. Another explanation for the color scheme is: According to Chinese popular superstition, the year of one's birth sign is full of potential misfortune, and one way to avoid the bad luck is to wear red color. When Chinese people typically fulfill this requirement by stocking up on crimson underwear, it might be that Mr. Jordan wanted a way to lay down some protection when he is playing some pick-up games. This special edition shoes were released to only a small number of stores in China at the beginning of February, and will land in a few more in China and a small number of stores in the U.S. on Feb. 19. Nike stores in Beijing and Shanghai last week has reported selling out of them instantly, and in Hong Kong, the shoes were only available via a lucky draw. Such limited edition Air Jordan shoes are not made for the common consumer, they are released in short supply, and quickly are snapped up by collectors, they are auctioned in eBay for upward of $400.This special edition isn't as ugly as last year's model, yet it's far from19932s Air Jordan IX, which was known to many people as the design that got cool years after its initial release.With its gold laces, red tongues and translucent soles, it might be a while before the Year of the Rabbit Air Jordan shoes are looked on so fondly.</p>
