LKM Elastisitas : Uji Kerenyahan

LKM ELASTISITAS : “Uji Kerenyahan”

A.    Rumusan Masalah

1.      Bagaimana mengidentifikasi dan menguji kerenyahan kerupuk secara fisika dengan alat sederhana?

2.      Bagaimana pengaruh jenis bahan terhadap kerenyahan kerupuk?

B.     Tujuan

1.      Mengidentifikasi dan menguji kerenyahan kerupuk secara fisika dengan alat sederhana.

2.      Menyelidiki pengaruh jenis bahan terhadap kerenyahan kerupuk.

C.     Hipotesis

Jenis kerupuk berpengaruh terhadap kerenyahan

D.    Dasar Teori

Bila suatu benda dikenai sebuah gaya dan kemudian gaya tersebut dihilangkan, maka benda akan kembali ke bentuk semula, berarti benda itu adalah benda elastis. Namun pada umumnya benda bila dikenai gaya tidak dapat kembali ke bentuk semula walaupun gaya yang bekerja sudah hilang. Benda seperti ini disebut benda plastis. Contoh benda elastis adalah karet ataupun pegas. Bila pegas ditarik melebihi batas tertentu maka benda itu tidak akan elastis lagi.

E.     Alat dan Bahan

1.      Alat

a.       Neraca digital

b.      Balok penekan

c.       Balok penyangga

2.      Bahan

a.       Keripik gadung

b.      Keripik melinjo

c.       Kerupuk ikan

F.      Variabel

1.      Variabel manipulasi           : jenis bahan

2.      Variabel kontrol                : ketebalan kerupuk, jumlah kerupuk

3.      Variabel respon                 : kerenyahan

The Wish

Hello, mafidandi mania (that actually, never real, hehehe. .)
Do you believe in “true love”?! I don’t! I think love is something invisible , and just talking about desire, maybe animal desire. I think the boys love the girls just because of their beauty. I always see with my normal eyes that the boys always love those girls who expose their beauty sexually. The girls always wanna attract the boys with their sexy side and naughty voices, for me that’s so shame!
I better never fall in love instead of loving a boy with bad (naughty) sight and attitude.
The surprising thing is, when I meet my old friends (boys) whom I think are the good personality boys, actually fall in love with naughty girls. In this world, I’ve never met the real good boy, who is (generally) caring, kind and not women-nicer (playboy). So, I must be very careful to take the love in my heart. I don’t wanna be disappointed by loving a cruel boy.
Mario Teguh had said, “Your soulmate is reflecting your soul”. So, If I had my way (another sentence to replace: I think or in my opinion) if a girl is good, she must get a good boy, too (and vice versa).
Now, I have to be a good girl in order I get a good boy, too. I’m confident one day I will hold my “Prince Charming”. I believe everyone has their own soulmate. God had choosen and matched His creatures with their soulmates properly. Hence, I’m never worried and doubt about this “confusing mess”. My life will go on and on!

Faktor_X

Hari ini aku bersama teman satu kelompok telah mengikuti grand final lomba senam satu angkatan. Tentu saja kita bangga, bahagia dan tak bisa diungkapkan dengan kata-kata semua yang terindah ketika pengumuman pada hari Sabtu minggu lalu. Namun sayang, kita tidak masuk tiga besar alias pemenang. Pada waktu kita tampil, terjadi banyak kekurangan di sana-sini, sering lupa, tidak kompak, pokoknya berantakan. Kita kecewa, pasti. Aku juga termasuk anak yang kecewa itu. Tapi kemudian aku berpikir, kita pasti bukanlah kelompok yang sangat buruk, kita sebenarnya bisa. Kalau kita kelompok yang buruk, mengapa kita sampai masuk ke grand final? Kita sudah berusaha dengan keras, kostum dipilih sedemikian rupa, menyewa instruktur terbaik, bahkan kita telah menghafal hampir semua gerakan senam ketika teman-teman dari kelompok lain masih keteteran merancang gerakan senam, kita pun kelompok yang paling rajin latihan senam setiap minggunya dibandingkan kelompok-kelompok lain sepengetahuan kita. Di saat tampil, kita telah tampil penuh percaya diri, semangat, kompak dan indah gerakannya. Semua yang telah kita lakukan adalah yang terbaik menurut kita. Jika kita tidak menjadi pemenang, mungkin itulah yang terbaik untuk kita, mengapa begitu? Karena kita telah melakukan semua yang terbaik. Kecelakaan yang terjadi bukanlah kesalahan kita, itu adalah faktor X yang datang secara tiba-tiba tanpa kita duga. Setiap kejadian yang terjadi pasti ada faktor X yang tidak kita duga, biasa kita sebut kecelakaan. Namun tingkat keparahan yang membedakan hanyalah besar kecilnya kecelakaan. Nah, besar kecilnya tingkat kecelakaan itu tergantung pada diri kita yang menganggapnya. Jika kita menganggap kecelakaan itu kecelakaan kecil maka kita akan bisa menerimanya, menerima segala keputusan yang terjadi dengan lapang dada. Tapi jika kita menganggap itu adalah kecelakaan besar, maka sekecil apapun kecelakaan yang terjadi akan terasa berat dan menyakitkan buat kita, dan jika ini dibiarkan akan menimbulkan petaka hati kita sendiri. Oleh karena itu, apapun yang terjadi pada diri kita, mari diterima dengan lapang dada karena itulah yang terbaik untuk kita sebab kita telah melakukan yang terbaik yang kita bisa. .

About islam

Hey, Hoe gaan dit met jou? Wat maak jou?
Hahaha, you must be confuse when you read my sentences. It mean: Hey, How are you doing? what are you doing? Its Afrikaans languages.
My friends, now I wanna tell you about my extraculicular. I join to karate (OSH!) and PMR. First time, I choose UKKI (Unit Kegiatan Kerohanian Islam. Islamic Religion Activity Unit). But I feel disappoint when the launching of UKKI, they show me and future member of UKKI a movie about Islam is a bad religion. Me (as moslem woman) feel sad, why moslems made a bad movie like that. This movie titled: "A Woman With Turban". It tells about a woman who got sexual abuse, broken home with her husband, and you know, blue film is concluded in (scene when a moslem woman made love with her boyfriend)! If you want to know more about islam and freedom, don't ever see that movie!
Islam is peaceful religion, with freedom and responsible. Our God never prevent us to study. Our prophet, asked us to study from born until die. And he also asked us to study until China (cause this country is far enaugh from Mecca). Thus, there's no forbidden to study every good thing. Give me your opinion!

closefriend

DeAr, FrIends! i wanna sHaRe mY fEElIng. i'Ve cLosefRieNd, his name is... Jessiano. He's from South Africa. But not only hi, I also have others closefriend, their name are: Angelique, Keenan, Jefferson, Jaylin and Ntombi. They all are from South Africa. They have a lot of same, nice, ridiculous, friendly but the difference of Jessiano with other my friends, he's the first boy who release his love to me (maybe the last). But I don't love him. Let you guess! You know friends, why I refuse him? I felt confuse that time. Yeah, he’s fine and love me as his future wife (he said to me! Swear! But I think it just bullshit). He’s long enough be my chatmate and I consider him just friend like Angelique, Keenan, Jefferson (Angelique’s boyfriend). Perhaps I like him, but I doubt I love him. No, NO! it’s too early to love someone who never face to face with us, right? Besides, I’m not ready yet able walk my day with sad, cry just because of broken heart. My junior high scool friend, just broke up with her ex-boyfriend. Early, when I arrived in the school I couldn’t find my classmates, I think they all still in their house. From house, I planned to cheat my friend because I couldn’t do my English homework. Almost every class still closed. I saw my friend who I met yesterday dating with her boyfriend, walked to her class and I interested to mock her. Then, I begin to mock her. But I was very shock when I mock her, suddenly she cry aloud. I feel so guilty and I said sorry to her. Without asking, she told me that she just broke up. She cry aloud. Then, I looked at her eyes, I couldn’t say a word! I never court and of course I never brake up. Yesterday and the days before it happen, sometimes I cried because nobody love me (except JC).you know, no boy (Indonesian people) ask me to be his girlfriend. And I cry my self. Am I too ugly? Am I too stupid? Like that, several questions stay in my mind. But, after know that broken heart is so bad, I give thanks to God. I believe, He give me the best in my life. The day before, I guess that being single is shame and horrible but now I realize that cry because of broken heart is more loud than cry because of single forever. Like me! You know, I’m not willing promotion ‘bout Oppie .A’s song, but I just tell my experience(never court). You know, when I tears because of single, I never tears until I go to school, but my friend did it. Yeah, I never feel what the sense of broken heart, so I can’t make her smile as usual. I only said, “You can trust me to save your secret safely.” A sentence which always I say if somebody tells about her secret. I can’t give her diamond words as wise woman, ‘cause I never brake up. Formerly, I force my self to hold a boyfriend. It shame if I don’t have a boyfriend. But, ‘till the end of Junior High School nobody ask me to be his girlfriend (again: except JC). Then, I realize that over force self to get something isn’t good to my physic and mental. So, I try make promise so that i’ll never force my self anymore. Now, I just wanna walk my day ordinarily, go with the flow (says Cinta Laura). Haha… Thus, What about you? Do you in an opinion with me?
