How to Draw a Graph of a Quadratic Function:

By: Dian Sulistiani / 2010110027

Before Revision:

How to draw a graph of a quadratic function:

Ø  Choose the quadratic function

Ø  See the function and determine the function is face up wards or face down wards.

Ø  Determine intersection point at x-axis. We can solve it with the step: substitute y = 0 into the function so we get x₁ and x₂ or we can use the factorization methods to solve the problem.

Ø  Determine the minimum or maximum point. We can use the steps: determine the axis of symmetry of x and substitute x into function. So we can get the y- value.

Ø  Determine the other points {x, y}

Ø  Plot the point {x, y} that you have found into Cartesian diagram.

Ø  Connect each point so we get the parabolic graph.

Ø  Or we can solve it by Geogebra software, please open the Geogebra software.

Ø  Input the function on input box and push the enter button.

Ø  We get the graph.

After Revision:

How to draw a quadratic function:

Ø  Choose the quadratic function. The general form of a quadratic is “y = ax² + bx + c”.

Ø  Determine the intersection point to x-axis if y = 0.

Ø  Determine the intersection point to y-axis if x = 0.

Ø  Determine the symmetry of x-axis. We can use the formula x = -b/2a

Ø  Determine culminating point ( -b/2a, (b² - 4ac)/4a), if a > 0 so, the function has minimum point and if a < 0, the function has maximum point.

Ø  Determine some of helping points. We can substitute x-value else into y so we get some other point (x, y)

Ø  Plot the point (x, y) that you have found into Cartesian diagram.

Ø  Connect each point so we get the parabolic graph.

Ø  Or we can solve it by Geogebra software, please open the Geogebra software.

Ø  Input the function on input box and push the enter button.

Ø  We get the graph.

Mathematics in My Memoriam

By: Dian Sulistiani / 2010110027

      I was not clever. My teacher ever said to my parents, “Dian, will live in TK before her ages fill the standard ages of Elementary students.” I was very sad. I did not like TK world. I thought that TK world only played and my friends were kids. I did not like it. So, I asked my father to move me in Elementary School. I was cry and threatened that I will not go to school again. So, my father asked my teacher to permit me in Elementary school. Finally, I will go to Elementary school.

       I struggled hard to get a good rank in first grade because if I did not get it, I will go back in TK. I must do anything so I can. The first lesson that I loved was Mathematics. I did not know why I like it. I like numbers, count, geometry and something like that. I counted anything that I saw it. I wrote the numbers in my door. So, if you go to my home in Blora, you can see it. My doors full my numbers in elementary school.        I like mathematics so much but I did not like memorized like PPKn. I hated it. So, my score only high in the mathematics score but other subject were bad. I got thirteen ranks from sixteen students. Oh God, that was so sad but I believed I can do the best thing. I always got the bad rank until the second grade in elementary school. It became my motivation in third grade. I studied hard. I made visual tools to learn mathematics such as one hundred of branch. I used it to count, addition, and subtraction of numbers. That was very interesting. I also studied hard in all lessons. Finally, I got fifth ranks in my class. That was great in my life. My parents and I were proud. That was like a dream.

      My achievement became my motivation. I studied hard until sixth grade in elementary school. My ranking balanced. I became ten top in my class. The last ranking in my elementary school, I got fourth rank. I was proud so much. I loved mathematics more and more. My elementary school was finished. Good bye my elementary school.

      When I was in junior high school, I got D class. I got a new situation. I thought that I must study hard again. I wanted the highest rank in this class. I had mathematics achievement. I still remember, the first topic in mathematics lesson was a set. I heard well for my teacher’s explanation. I studied carefully. The first score in my mathematics examination, I got one hundred. It was a highest score in my class. I was proud. It was my motivation that I can do it in my other subject. Yup, my struggle did not finish until it. My way still long time. I struggled, struggled and struggled. My parents supported me so much. Finally, I got the first rank in my class.

      The next year, I always got three top ranks in my class until third grade in junior high school. My mathematics score always above eighty. I had my unforgettable memoriam of mathematics when I got the perfect score in my National final examination. Yup, I got one hundred in mathematics subject. Wow, that was great. 100 in UN? It was like dreams. My junior high school was finished. Good bye my Junior High School.

       The next school was Senior High School. I got second top rank in list of my cohort. So, I got X2 in this year. I always thought that I must get the highest score. Yup, it was OK but after I was more adult than before, I did not thought highest score. It was only score, right? I think the process is more important than score. It was proven. My score was standard like my friends. But I have studied about the process of lesson. It made me became the different people. I love myself. Finally, my teacher said, “Dian, you will be a representation of school in mathematics Olympiad. I believe you can do it.” Oh my God. I was like a dream. I wanted it from I was in elementary school. I always dreamed about that. I was proud to hear it.

        I studied hard to join the Olympiad. I struggled hard but I have not got the best thing yet. I failed to be winner. I was sad but it just a game. I must try again. I believed I can do it one day. It is OK.

      The next semester, I always got three top ranks in my class. I ever got mathematics score in my report was 96. It is high score, I think. My teacher supported me so much. My friends gave spirit for me, “Okay Dian. You can do it.” I am proud them. My teachers are my motivation. I pay attention so much for their explanation. One day, I imagined that I am mathematics teacher. Wow, that is great. I loved mathematics and science lessons so much. It will be my motivation. I wanted to be a mathematics teacher.

       In 2009, the last semester in senior high school, I had a big problem. I wanted to be teacher so I must be university graduate but my parents have not money for it. So, I tried to join UGM scholarship. I took a pure mathematics subject. But Allah gave other ways for me. I failed for UGM scholarship. I was very sad. It made broken heart for me. I was stress and hated my self. My parents were very sad.

       One day, Allah gave lightness for me. I got up again. I studied hard again. I loved myself again. Although my mathematics in National Examination, I got 60 but I was happy. I want not disappointed again. I believed, I will be great on one day. I tried again for scholarship. I found ITB Untuk Semua Scholarship. I took a mathematics subject but I was not afraid again. I prepared the best thing. If I fail again, that is OK. I waited the announcement well. Finally, Allah gave other ways again. I failed but I still kept spirit. I believed, one day, I will be a mathematics teacher.

       After senior high school, I worked in bakery store. I became cashier. You can know my job, right? Yup, I managed money in the store. I worked carefully. I was happy, I got the mathematics again. I can know how to add and subtract the mathematics in cashier program. I worked hard until one year and I always dreamed that I will go the campus.

       Finally, in 2010, I tried scholarship from Sampoerna School of Education. I was not afraid for fail again. I must keep my spirit. Alhamdulillah, Allah gives the best thing for me. SSE accepted me in mathematics department until now. I met many great people in here. Mathematics is one of my motivations in my life. I studied many experiences and a new method in SSE. I have so many great families that they always support me to be a great people. I love SSE, mathematics, my parents, my brother, my family, my friends, my lecturers, and all people that always support me. Actually, my dreams to be a mathematics teacher will be real in my life soon. Thank you so much, God.

         Thank you for all. Mathematics is fun and unique. Do the best thing but do not ask something be the best. ^_^

Diary of Mee

Oleh: Cantika Diptra

Jari-jari kecil itu menggenggam sebuah pena. Sekali dua kali pena itu bergerak sesuai kata hati. Sebentar-sebentar gadis itu menatap kalender. Menatapnya lekat namun terasa aus dan kosong. Secarik kertas telah penuh coretan tangan mungilnya. Ada apa gerangan ?

Mee hanya menuangkan perasaannya. Perasaan yang selama ini dia pendam, tak ada yang tahu kecuali dirinya dan satu lagi, Tuhan. Ditatapnya tulisan itu tajam. Lekat dengan memori yang kian tak berujung itu. Dia membaca ulang dalam hati, yang sunyi.

 “Ketika Mei bertemu lagi. Tuhan, andaikan aku boleh memilih, aku akan memilih untuk tidak ingin memiliki rasa cinta pada satu orang itu. Aku tidak mau menyakiti orang lain. Walaupun aku tahu aku tak bisa melupakan dia, namun aku harus rela, mau tak mau aku harus mengerti, siapa diri aku dan siapa dia. Semua hal itu mustahil untuk terus dipertahankan. Sayangnya cinta tak mau bersahabat denganku. Entahlah, apa maksud semua ini. Aku tak mengerti. Aku takut, sangat takut lebih tepatnya.

Tuhan, ingin aku menangis, ya menangis sejadi-jadinya, agar aku bisa mengerti semua hanyalah mimpi. Tak ada yang perlu dimengerti dan tak ada harapan lagi untukku. Aku menyerah demi sebuah kebaikan. Tanpa harus ada yang tersakiti, aku mundur. Aku tahu, aku harus mundur sebelum semuanya terlambat. Aku tak bisa melanjutkan semua ini. Cukup sudah.

Andaikan waktu dapat berputar kembali. Aku ingin kembali ke waktu pertama kali perasaan ini muncul. Aku akan menghindar darinya. Aku tak akan memberi saran agar dia potong rambut, aku tak akan minta cara dia berbahasa Inggris, aku tak akan menghabiskan waktu hanya untuk berlama-lama bertatap muka dengan dia, aku tak akan pulang larut malam dari kampus di hari Rabu, aku tak akan merubah penampilanku, aku tak akan dandan seperti sekarang, aku tak akan menangis saat UET, aku tak akan mencari tahu apa kesukaannya, aku tak akan kagum dengannya, aku tak akan terkesima saat dia mengungkapkan pendapatnya, aku tak akan membantu dia ngepel, aku tak akan naik sepeda mampang-depok, aku tak akan duduk di paling depan, semua itu hanya untuk dia. Sayangnya aku tak akan pernah mampu merubah waktu.

Waktu terus berganti hari berganti waktu. Aku tak mampu mengubahnya. Tuhan, beri aku kesempatan sekali lagi untuk mengerti. Meiku tak berujung lagi. “

Mee tak memiliki semangat lagi… Air matanya pun tak mau ambil risiko. Dia menangis sejadi-jadinya. Menangis tuk mengurangi luka. Luka yang bertahun-tahun telah menyakiti hatinya.

Tak Dapat Pepe Katakan, Ayah

2009. Angka-angka itu membuat Pepe dilema dalam pemikirannya sendiri. Sebuah hal terberat dalam enam belas tahun usianya. Entahlah…

Menginjak kelulusan dari SMA itu rasanya kehidupan ini berubah drastis. Keinginan untuk kuliah harus pupus di tengah jalan. Semangat yang dulu bergejolak kini mulai redup, redup, dan hampir mati.

Ayah Pepe yang dulu kekar besar kini mulai mengurus. Sejak tiga tahun yang lalu, ayah terserang penyakit yang tak tahu sebabnya. Mulai batu ginjal, sariawan kronis, dan yang terakhir adalah hemoroid. Perih rasanya, di saat ayah merintih menahan penyakit. Tak tega rasanya, sungguh, melihat ayah harus terbaring lemah tak berdaya.

Segala macam usaha telah dikerahkan. Pergi ke dokter spesialis, rumah sakit, orang pintar, kyai, bahkan para peramu obat verbal pun sudah namun tetap saja nihil. Segala barang berharga harus dijual ibu untuk biayanya. Pepe tak bisa membayangkan, bagaimana rasa sakit ayahnya, bagaimana jerih ibunya untuk mencari uang lagi. Dia benar-benar tak bisa menerima semuanya. Kondisi keluarga sangat sulit, dia yang harusnya malu, tak bisa melakukan apa-apa untuk membantu orang tua.

Hal tersebut membuat ibunya harus membanting tulang menghidupi keluarga. Pepe sebagai anak paling tua pun sangat terpukul dan menyerah. Apalagi keinginan untuk kuliah akan putus di tengah jalan karena kurang biaya. Di samping itu, dia masih punya dua adik yang akan melanjutkan sekolah di SMP dan SMA. Pasti tidak akan sedikit biaya yang mereka butuhkan. Rasanya stress tak kuat menerima cobaan ini.

Namun, pandangan dan tekad tiada pernah mati. Berbagai macam cara Pepe cari untuk bisa kuliah. Dia mencoba mencari beasiswa dari internet. Ya, hanya dengan beasiswa, dia bisa membantu meringankan beban orang tua. Pengalaman kegagalan dalam seleksi Beasiswa UGM jalur PBUTM 2009 dan beasiswa ITB Untuk Semua 2009 telah membuatnya tegar. Mungkin keberuntungan belum berpihak padanya. Dia tetap tidak putus semangat. Kegagalan pada dirinya adalah guru yang paling baik dalam hidup. Akhirnya, dia memutuskan untuk menyimpan sejenak impian kuliahnya itu.

Dia coba kembali melamar kerja di sebuah toko roti. Alhasil dia pun diterima. Dari sinilah Pepe mulai mendapatkan pengalaman baru. Pengalaman pertama kalinya bekerja, mencari uang sendiri. Penghasilannya lumayan cukup untuk tidak merepotkan orang tua. Setidaknya dia bisa menghidupi sendiri kehidupan yang sementara ini.

Tahun 2009 terlewati sudah dan kini tahun 2010 menyapa. Suatu hari, dia teringat akan impian-impian yang menjadi tujuan hidup yang pernah tersimpan sementara. Salah satunya adalah kuliah. Dia bertekad untuk bisa kuliah. Niat baik adalah hal yang teristimewa dalam hidupnya. Dia mendapat informasi beasiswa dari salah satu sahabatnya. Ya benar, beasiswa SSE 2010. Kabar baik itu sangat dia perjuangkan. Hingga akhirnya dia pun dinyatakan lolos dan diterima di SSE. Air mata ungkapan rasa syukur. Dengan ini, Pepe hanya ingin mengatakan, “Ayah, ini kado ulang tahun ayah, 13 September 2010. Aku kuliah”. Kehidupan telah berubah.

Perenungan untuk Bertemu Illahi

Oleh: Dian Sulistiani / 2010110027 / Section A

“Siapa itu Tuhan? Mengapa Tuhan tidak terlihat? Kalau Tuhan ada, coba saya ingin makanan sekarang. Mana kok Tuhan belum beri mkanan juga?” begitulah tanggapan seorang anak tentang Tuhan. Konsep ketuhanan merupakan salah satu hal yang sering kali menjadi pertanyaan setiap individu. Pandangan mengenai bentuk dan wujud Tuhan tergantung dari diri masing-masing manusia dalam memreprentasikannya. Sering kali kita menempatkan Tuhan sebagai sesuatu yang ghoib atau tidak tampak namun ada. Sebenarnya konsep ketuhanan tidaklah untuk diperdebatkan namun Tuhan sebagai Sang Pencipta untuk diyakini. Walaupun Tuhan tidak tampak (ghoib) namun kekuasaan-Nya begitu luar biasa yang dapat kita nikmati setiap waktu. Semua tergantung masing-masing individu dalam memaknai Tuhan itu sendiri.

Berbicara seperti apakah bentuk Tuhan, semua itu sulit untuk dijelaskan. Tuhan tidak tampak namun masih bisa dirasakan bagi orang yang menyakini. Kita yakin doa dan harapan yang kita haturkan kepada Tuhan akan terwujud. Jika kita telah mencapai impian kita itu, sering kali kita lupa untuk bersyukur kepada Tuhan. Padahal semua yang terjadi, kita percaya semua adalah milik Tuhan. Coba saja bayangkan seandainya Tuhan tampak di mata manusia? Pastinya semua orang akan mengikutinya dan antri untuk meminta Tuhan mengabulkan semua keinginan. Jika kita pakai logika kita, bagaimana mengatur rezeki, takdir, dan lain sebagainya, siapa yang berkehendak? Semua itu atas kekuasaan Tuhan.

Mari kita renungkan sejenak. Bumi yang kita pijak, hewan, tumbuhan, laut, dan berbagai alam semesta ini, siapa yang menciptakan? Atau jika kita melihat langit, menembus jauh ke luar bumi, bermiliaran benda angkasa berada. Kita juga menemukan sebuah ruangan tanpa batas berada di sana. Atau yang lebih simple lagi, kita sebagai makhluk hidup setiap hari bernafas dan butuh makan. Dari mana datangnya udara dan berbagai sumber alam? Kita sebagai makhluk yang berakal seharusnya dapat berfikir mengenai itu semua.

Jika ditanya apa kepercayaanmu? Pastilah penulis menjawabnya Islam sebagai agamaku. Sebagian besar manusia yang terlahir dari keluarga dan lingkungan mayoritas Islam maka kemungkinan besar manusia itu akan memeluk Islam. Begitu pula dengan agama lain selain Islam. Apapun agama seseorang bukan menjadi masalah karena agama menjadi hak masing-masing untuk memilih dan meyakininya. Menurut penulis, semua agama mengajarkan kebaikan hanya saja sedikit berbeda tentang cara implementasiannya. Semua mengajarkan kita pada kasih sayang dengan orang lain.

Tempat Tuhan yang terdekat adalah berada di hati masing-masing hamba-Nya. Menjadikan pedoman untuk kebaikan dalam menjalani hidup. Mengatur segala kehidupan yang ada di bumi dan di langit. Bukankah Tuhan telah menunjukkan kekuasaannya akan alam semesta ini? Lalu apakah kita tetap memperdebatkan tentang kekuasaan Tuhan? Semua itu perlu menjadi refleksi kita dalam kehidupan ini. Alangkah baiknya kita sebagai hamba yang taat kepada-Nya, bersyukur terhadap apa yang telah ada.

Perbedaan Identitas bukanlah Penghalang Persatuan

Oleh: Dian Sulistiani

2010110027/Section A

“Kita begitu berbeda dalam semua kecuali dalam cinta…”

--Soe Hok Gie--

Begitulah serangkai kata yang memberi secercah harapan dan penguatan dalam diri saya tentang sebuah perbedaan. Saya yakin setiap individu pasti tidak ada yang sama persis dengan individu lainnya. Walaupun banyak persamaannya namun hal tersebut pasti ada beberapa segi  yang berbeda. Hal ini telah menjadi anugrah Sang Pencipta kepada kita semua. Sayangnya tidak semua individu berhasil untuk berefleksi dan memahami sebuah perbedaan tersebut.

Berbagai macam perbedaan itu sangatlah nyata di kehidupan sehari-hari. Jika kita tengok kembali di sekeliling, kita akan menemukan berbagai keistimewaan tersendiri. Keanekaragaman telah melekat kuat di jiwa bangsa Indonesia. Banyak suku, agama, ras, adat, warna kulit, dan kebudayaan yang pastinya berbeda dari masing-masing individu maupun kelompok masyarakat. Semua itu bergabung dan menjadi ciri khas dari sebuah identitas seseorang dalam masyarakat.

Berbicara soal identitas, saya memiliki perspektif pandang dan definisi sendiri tentang hal itu. Identitas seseorang kebanyakan dilihat dari suku, agama, dan status sosial. Misalnya saja, saya lahir di daerah Jawa dan dari orang tua berkebudayaan Jawa juga. Maka dapat dikatakan bahwa identitas saya sebagai orang Jawa. Lalu bagaimana dengan teman kita yang ayahnya dari Batak, ibunya dari Sunda, tetapi dia lahir di daerah yang berkebudayaan Jawa. Bagaimana dengan identitasnya? Apakah dia termasuk orang Batak atau orang Sunda, atau bahkan orang Jawa? Menurut saya, untuk menentukan identitas suku seseorang sebaiknya kita perlu memilih dan memutuskan sendiri mana yang sekiranya kita nyaman berada di dalamnya. Kalau kita memang telah nyaman menjadi orang Jawa maka lebih optimalkan dan lebih selami lagi apa itu Jawa. Namun lantas kita jangan bertindak egois dengan keberadaan yang lain. Kita harus menghargai dan menerima keadaan serta pilihan orang lain di sekitar kita.

Kemudian, identitas seseorang saat ini sering dikaitkan dengan identitas keagamaan. Berefleksi setelah membaca Kompas (26/2) yang membahas tentang persoalan nasib minoritas. Di dalamnya ada pernyataan bahwa sentimen kebangsaan telah dikalahkan oleh sentimen keagamaan. Hal tersebut sering terjadi di kehidupan kita. Berbagai masalah misalkan saja penghalangan hak para pemeluk agama minoritas oleh pemeluk agama mayoritas mengenai tempat peribadatan. Secara pribadi saya menolak hal tersebut walaupun posisi saya sebagai pemeluk agama mayoritas di lingkungan saya berada. Identitas seseorang hanya dilihat dari segi agama saja. Bisa saja suatu waktu kita akan menjadi kaum minoritas di daerah lain. Apakah kita masih akan berlaku seperti itu? Mari kita renungkan jika kita alam posisi kaum minoritas. Saya setuju bahwa sifat kebangsaan dan kesatuan kita seakan-akan telah luntur oleh sikap egois dan hanya memandang orang lain dari salah satu segi saja.

Kebanyakan orang belum bisa memandang sesuatu dari semua segi tidak terkecuali saya. Banyak orang yang beranggapan orang Jawa itu lemah lembut. Namun apa yang akan Anda katakana saat bertemu dengan saya? Saya lebih suka dipanggil sebagai orang Jawa karena saya telah nyaman dengan Jawa. Namun saya tidak lemah lembut seperti yang orang katakan bahwa Jawa pasti lemah lembut. Apakah karena tidak lemah lembut lantas saya bukan orang Jawa?

Terkadang saya berpikir tentang pandangan-pandangan yang hanya dari satu pihak saja seperti stereotype, telah meracuni pemikiran kita. Pandangan tersebut seolah telah terpatri dalam memori. Bahkan saya masih sering terhasud oleh stereotype itu. Misalkan saja ketika saya mendengar kata Madura, yang terlintas di benak saya adalah orang Madura itu keras dan galak. Padahal dalam kenyataannya tidak semua orang Madura keras dan galak. Itulah mindset kita yang kadangkala membuat kita ragu untuk bergelut dan mendalami orang lain yang sebenarnya.

Langkah awal kita agar persatuan tetap ada di lingkungan yang beragam sebaiknya kita saling toleran dan peduli dengan sesama. Lebih mengenal identitas diri sendiri dahulu sebelum mengenal orang lain. Kalau kita saja tidak mengenal diri sendiri kapan orang lain mau mengenal kita? Jika ditanya apakah kita harus toleran dan peduli dengan orang lain yang tidak tolran dan tidak peduli terhadap kita? Saya menjawab harus sebab sebelum kita meminta dipedulikan dan dihargai orang lain, kita harus bersikap peduli dan menghargai orang lain terlebih dahulu. Dengan sendirinya timbal balik antara apa yang kita beri dan apa yang kita terima pasti ada. Oleh karena itu, tunjukkan bahwa diri kita dihadapan orang lain itu baik dan berarti bagi lingkungan sekitar.

Setiap perbedaan pasti saling melengkapi satu dengan yang lainnya. Keberagaman di kehidupan kita merupakan khasanah yang sangat berharga dan wajib kita lestarikan sebagai jati diri bangsa. Keanekaragaman untuk menguatkan persatuan dan kesatuan, saling memiliki satu dengan yang lainnya, bukan malah pemecah belah.

Mathematics is Fun

source:  http://msmcdaniels1stgrademathmaticians.blogspot.com/

What is mathematics? I am sure, we think some numbers, formulas, or x and y may be. Yups, that is not false. We are often say that mathematics is difficult, right? Okay, in here, we are going discuss about mathematics. Do you know, Guys? I have some opinion about that. Okay, are you ready with our discuss? Sippp, I will begin.

First, mathematics is a mother of science. Yups, I agree with that statement because mathematics is a ground of other science such as physics, biology, chemical and else. Do you remember? Okay, we can find that in physics. For example, we learn about acount numbers, or integral to find a speed value or acceleration or else. we can learn that in mathematics. It will be explored in mathematics. In mathematics, we learn about logic, arithmetic, algebra, geometry, probability, statistics, and calculus. So, we are not only learn about numbers but also we learn about logic statement. Mr. Rahmat Sagara said, “Do not ask about the benefits of science that we learn but believe that science has benefits for you.” Yups, I agree with him.

            Second, mathematics is language. Do you agree with me? Mathematics is often called “Language of nature” because it is so useful for modeling the natural world. We can find formulas of nature and go back in nature. That is not easy but we need try, Guys. In mathematics, we can reduce the problem in world to be a simple formulas or language. The mathematics symbol is familiar context so that can learned by all people. we can communicate with mathematics. We can use them to solve our problem.

            Third, mathematics is art. Do you remember? May be, when you were in elementary school, the teacher gave a shape, such as rectangle, circle, or cube for you. Or, you drawn a graph or else. Do you know? You have to draw a art. How to put the point in cartesian diagram, that need art skill. Do you know, again? If we connect a point by point, we can get a shape. That is very interesting, right?

            Fourth, mathematics is fun. We can play with mathematis. We can search a pattern of formula. We can learn about many shapes. That is interesting. Mathematics is not only formula but also anything in nature are mathematics.

We can find and need mathematics. For example, if you are a wife-house, you need mathematics to determine a food composition or manage your family’s money. Or, the dustman also need mathematics in their life. They need mathematics to manage their money or monthly income in their life.

Mathematics is very important for our life. So, Indonesian children should understand well. Actualy, mathematics is not difficult, but our mainset make that to be difficult. So we are new generation of teacher must change the bad mainset of students about mathematics. We as teachers candidate so we must make a fun teaching and learning process so that students can enjoy that. Do not be a cruel teacher. Make students have motivation to learn mathematics. Good Luck.

That’s Me

What is the meaning of name? This is the phrase that we often hear. But, whatever definition or explanation about the name, I think the meaning of name is an important part of life. The name is something historic in life. It is also an implicit part of a prayer and hope.

Okay, in here I will try to share about the name, may be, you also have name as my name. Nothing is impossible. Firstly, I want to introduce myself. My name is Dian Sulistiani. Actually, it is difficult for me to explain what is the meaning of my name. The name was a gift from my parents. That is not only a name but that is a unique story of my life. Okay, I will explain my name story. Actually, I am not the first child of my family. I still have a sister, but when my sister was born in this world, the condition of my family was less supportive families. My father was seriously ill and the economy was so bad. Some day after the birth of my sister, God took back her. Like or not, my parents must be willing that.

My parents believed God give us the best anything. After one year, my mother pregnant again. After 9 months and 10 days, a baby girl was born. My birth was not given any changes in my family. But both my parents were proud and happy. I gave a new life and new expectation. So, my parents found the best name for me. It is Dian Sulistiani. According them, as a first daughter that she life and one day will be a guide for younger, Dian is perfect. My father said that Dian is light source, Sulistiani is a good woman. So, in my opinion, Dian Sulistiani is a good woman that can be lighter to other in every time and anywhere. I believe, my parents give my name like that’s, they hope so that their children become a good people in attitude, character, and great dreams. May be if I related in my historic of life, my name is very important. A expectation of my parents. That all are the meaning of my name that is my opinion.

Perhaps because my name, I grew up be a person who has the courage, have give up and most importantly, how can I change the lives of all the things around me for the better. I am proud to be the names of both parents. I think that is perfect for me. I am comfortable with it. As people that have the name, I always try to achieve that dream of my parents. I love my parents so much, my parents are very good at choosing names for their children. I am very fortunate.
