Ali Baba and the Forty Thieves

          Ali Baba was such a poor man that he had only one shoe for his two feet. Even the mice in his house are hungry. One day, his wife said, we have no food in the house. No rice. No potatoes. Go and collect leaves in the forest so that I can make a soup.
          Ali was a lazy man. He looked for leaves for about ten minutes and then he climbed a tree to sleep. He was afraid of wolfes. When he woke up he was surprised to see forty thieves on forty horses. They stopped in front of a big rock.
         “Open Sesame!” shouted the leader.
          A door in the rock opened. The thieves carried sacks full of gold into the cave. When they had finished the leader shouted, “Close Sesame!” and the door closed.
As soon as the thieves had disappeared Ali Baba jumped down the tree, said “Open Sesame!” and went into the cave. There were sheives all around the walls. The shelves were full of sacks which are full of gold. Ali took a sack home with him.
          Unfortunately one of the thieves saw Ali’s footprints on the sand. He followed them to Ali’s home. He took out his knife and made a cross on the door. “Now I shall know which house it is”, he said. Then, he rode off to get the other thieves. But Ali has seen the thief. He and his wife took a room and swept away the footprints. Then he made crosses on every door in the street.
          When the forty thieves arrived they had their knives between their teeth. But they never found Ali or the gold. Ali and his wife lived happily ever after.

           Many years ago, there lived a hermit in a forest in Sumatra. He did not grow food but depended on jungle fruit to survive. Soon, there was a drought, and all plants and fruit trees in the jungle died.
The old man had nothing to eat now, so he return to begging. He went to a nearby village trying to get some food. At first, the villagers were happy to help him. However, when he came continually, they refused to give him anymore food. They told him to grow his own food..
           One day, while the hermit was sitting in his hut, sad and hungry, he bagan to think about growing his own food. Just then, a boatman stopped by, and taking pity on the hermit, give him some paddy seeds.
Before the boat man went away, he said. “These seeds will grow and give you everlasting harvest if you work very hard. If you are tired of the work, the paddy plants will turn into weeds”.
           The old hermit worked hard to clear the land and sowed the seeds before the rains came. Strangely, after a short period of time, the paddy was ready for harvesting. The old man got a lot of rice from the harvest. After each harvest, the plants grew back again right way. When the villagers heard about the hermit and his wonderful paddy, they flocked to his paddy-field and took home as much paddy as they could
            One day, the hermit became so tired of harvesting the paddy that he shouted, “Oh, stop growing, you wretched thing!” As soon as he had said this, the paddy plants turned into weeds.

Sticky Finger

                 After breakfast, I sent the children to school and then went to market. It was still early when I returned home. The children were at school, my husband was at work and the house was quiet. So I decided to make some tarts for tea. In a short time, I was busy mixing butter and flour and my hand were soon covered with sticky pastry. At exactly that woman, telephone rang. I picked up the receiver between two sticky fingers and was dismayed when I recognized the voice. It was Mrs. Bates. It took me ten minutes to persuade her to ring back later. At last I hung up the receiver. There was pastry on my fingers, on the telephone, and on the door-knobs. Suddenly, the bell rang, very loudly. This time it was postman. He wanted me to sigh for registered letter. What a mess!

The Oil Formation

                It was widely known that oil was funned from the remains of plants and animals that lived in the ocean many millions of years ago. The most familiar plants and animals that had formed oil were algae and plankton. They were accumulated on the seabed and were buried from under layer of sediment. They were not decomposed because the sediment preserved them from the process of decomposition. Instead the organic matters were trnsformed by the action of bacteria into substance called kerogen. Over long periods of time, further layers of sediment produced increased temperature and preasure which changed the kerogen into many different hydrocarbons.
               Atoms of carbon and hydrogen join together in a number of characteristric arrangements to form hydrocatbon molecules. The smallest and simplest hydrocarbon is methane, which has a molecule consisting of a single carbon atom surrounded by four hydrogen atoms. Larger and more complex hydrocarbon have molecules made up of a chain or ring of carbon atoms. Benzene has a molecule consisting of six carbon atoms that form a ring; ecah atom has one hydrogen atom. Hexane consists of a chain of six carbon atoms.                The first and the last atom of the chain have three hydrogen atoms, while the four carbon atoms in the middle have two hhydrogen atoms each. That is why crude oil can be thick and dark, or pale and thin.

Honey

                  Honey is among the olderst type of natural food known to mankind. Its consumption has been recorded in ancient civilization, and for many races it was the only sources of pure sweetness. It was widely believed to have health-giving propertied, the journal of ansient doctor contained references to honey as the most important ingredient in their medication
                  The ancient Greek believe that eating honey can increase man’s life span by almost double. In the early Olympic Games athletes took honey to perform better and after the games, to restore their strength. In the modern times it has beebn proven that honey can prevent and cure all kind of illnes. Germs of dysentry, typhoid, pneumonia and variety of other diseases died soon after they placed in pure honey.
                 Honey is rich of vitamin and because of its hig food value, it is better than any other type sugar. It has been converted into simple sugar bey bees, so it easy to digest and releases energy quickly. Besides, it never goes bad, as it was found in Egyptian tombsafter thousand of years honey was still dood enough to be eaten.

Laptop Thief Targets Boarding Students

DEPOK: The police detained a 22-year-old woman who had stolen 26 laptops from University students boarding in Beji subdistrict, Depok municipality.
Depok police deputy chief Adj. Sr. Comr. Ahmad Kamal said that the suspect, Irene Agni Swastika, had enganged in the crime mastermided by her father for a year.
“The father, who is still on the run, set up everything for her. He had surveyed the boarding house, made room key dupleicates, and called up the tarteted victims to make them leave the boarding house. Irene would use the keys to get the laptops. She used to pretend to be the victims’ friend,” He was quoted by tempt.co over the weekend.
Irene was caught red-handed by the owner of Wisma Gardenia boarding house when she was about to leave the house.
The police confiscated one laptop and 153 room key duplicates from the suspect as evidence.

  • The aim :

         To know the difference of growth and development of peanuts in different concentration of fertilizer

  • Basic Theory:

         Understanding of plant growth and development:
         Growth is the increase / change in the form of quantitative (observable) that occur in living things, while development is a qualitative change (can not be observed by naked eye), both of which are irreversible, that can not change back into shape, example : plants that have grown can not be naturally short again as before, the ripe fruit can not be young again as before.
         The factors that affect plant growth and development (all factors that affect the anabolism / catabolism plant):

  1. Food / nutrition
  2. Water
  3. Air
  4. Humidity
  5. Light

           Dirt goats / sheep contain a fairly high organic C is generally widely used for fruit crops. plant is potted or in the soil directly. Goat manure fertilizer rugged durable so that it can diapakai long time since round.
           Organic farming is growing and requires increased supply of organic fertilizer. Among the potential to be developed in Indonesia is a liquid fertilizer from manure / feces (biokultur) and from urine (biourine) goats.

            Quality of both types of liquid manure from the goats are good enough to be applied to crops and plantation crops. I Made Londra from BPPT Bali which describes how the manufacture of liquid fertilizer from fermented sewage treatment express goat carried on the manufacture of liquid fertilizer can increase the content of nutrients.

             In the manufacture of liquid manure from goat manure (biokultur), contain elements of K and organic C and N increased drastically compared with no treatment. Ie, 962 ppm compared to 422 ppm for K, 3414 ppm compared to 2811 ppm for C-organic, and 1.22% from 0.27% for N. While the elements of P up to 84 ppm compared to 69 ppm.

             In making biourine goat, the content of the element K jumped to 1770 ppm compared to 759 without treatment. C-organic rose to 3773 ppm compared to 3390 ppm, and N 0.89% compared to 0.34%. But the element of P down to 89 ppm compared to 94 ppm.

             The decrease in the P element caused biourine inoculant that is less able to solubilize P. So need to look for microbes that are suitable for dissolving more P in the process of fermentation biourine.

             The technique of making a fairly practical and simple outlined as follows. In making biokultur, stool (feces) and goats housed in a tub of water mixed with a ratio of 1:2. Then put fermenter, namely R. bacillus and Azotobakter with the composition: 0.8 m3 feces mix, 1 liter R. bacillus and 1 liter of Azotobacter.

             The material was stirred for 3-4 hours, then the vessel is closed and left for 7 days. On day 8, the fluid above was taken, the sediment is squeezed and the liquid is combined with a liquid that has been taken previously. The liquid form of liquid fertilizer (biokultur) is already ready for use or stored. Solid parts of the juice can be used for fertilizer or fuel.

  • Hypothesis

          Peanut plants grown in soil with fertilizer concentration of 50% will grow more fertile and give effective results compared to the other pots, because at this concentration plants get element - the element that is suitable for optimal growth and development.

  • Variables

          • Independent variable : goat manure with different concentrations
          • Dependent variable : The stem length or height of peanut
          • Control variables : The light, water, soil, air,


  • Tools and Materials:

          - Peanuts
          - Soil (as the medium)
          - Pot
          - Water
          - Fertilizer (kotoran kambing)
          - A ruler
          - A camera



  • Steps of work

         1. Prepare the tools and materials needed

         2. Mix the soil and fertilizer
             a) Pot 1 (25% of fertilizer)
             b) Pot 2 (35% of fertilizer)
             c) Pot 3 (50% of fertilizer)
             d) Pot 4 (65% of fertilizer)
             e) Pot 5 (80% of fertilizer)

         3. Plant the peanuts underground

         4. Water the plant on each the pot with same amount

        5. Observe the growth and development of plant (peanuts)

        6. Write down the result of observation



  • Conclusion

          - The best growth and development of peanut plants is experienced by the pot with concentration of     25% (pot 1).
          - The peanut plant will not grow and develop well in so much fertilizer.


  • The result of discussion (Answer-Question)
Question : apa fungsi nitrogen dan karbon yang terkandung pada pupuk bagi tanaman kacang tanah ?

Answer : fungsi nitrogen dan karbon yang terkandung dalam pupuk kotoran kambing adalah untuk merangsang hormon-hormon yang memacu pertumbuhan kacang tanah.
Question : Pada hari ke berapa biji baru mulai tumbuh setelah percobaan pada pot ke-2 gagal?
Answer : Biji kacang tanah ditanam kembali dan baru tumbuh pada hari ke-8.
Question : Mengapa tanaman kacang tanah pada pot1 dengan konsentrasi 25% tumbuh paling cepat dan subur ?
Answer : Karena berdasarkan percobaan, tanaman kacang tanah tersebut ditanam pada medium dengan konsentrasi yang tepat.
Question : Kapan tanaman kacang tanah akan dapat dipanen?
Answer : Tanaman kacang tanah dapat dipanen dalam jangka waktu kurang lebih 3 bulan setelah penanaman dengan perlakuan yang rutin.

Sebelum membahas jauh tentang "Redoks dan Elektrokimia", aku pengen cerita sebentar sama temen - temen semua, bahwa salah satu materi kimia ini akan kita pelajari di kelas XII semester pertama. Sebenernya aku udah mempelajari materi ini sejak kelas X dulu. Lho kok?? eitss jangan salah, sejak kelas X aku udah masuk tim olimpiade kimia di sekolahku, so aku harus belajar mandiri untuk semua materi - materi kimia di SMA, termasuk mempelajari materi kelas XII sebelum waktunya.wekekeke
Sebenernya waktu masih kelas X itu aku masih perkenalan sih sama "Redoks dan Elektrokimia", baru setelah kelas XI aku mempelajarinya lebih dalam. Dan sekarang (terenggg) aku udah kelas XII, jadi aku udah nggak asing lagi sama materi kimia yang satu ini. yaa tinggal mengulang aja sih :DD

Dalam materi ini ada beberapa kata kunci; Reaksi Reduksi, Reaksi Oksidasi, Biloks, Sel Volta, Elektrolisis, Anoda, Katoda, Jembatan Garam, Deret Volta, Energi Kimia, Energi Listrik, Hukum Faraday (kira - kira itu)

>> Reaksi redoks merupakan gabungan dari reaksi reduksi dan oksidasi.
ini nih karakterisitik reaksi reduksi dan oksidasi
a) Reduksi:
- Penurunan bilangan oksidasi (biloks)
- Pelepasan oksigen
- Penangkapan elektron
b) Oksidasi:
- Kenaikan bilangan oksidasi (biloks)
- Pengikatan oksigen
- Pelepasan elektron
contoh reaksi redoks:
H2(g) + CuO(s) → Cu(s) + H2O(l)

Setelah ini, kita akan membahas mengenai deret volta
Li-K-Ba-Sr-Ca-Na-Mg-Al-Mn-Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb-[H]-Sb-Bi-Cu-Hg-Ag-Pt-Au

di atas tersebut merupakan deret volta, dimana deretan unsur-unsur yang terletak semakin ke kanan dari unsur H, maka unsur tersebut bersifat lebih positif potensial reduksinya semakin besar (katoda), sedangkan semakin ke kiri dari H, unsur tersebut bersifat lebih negatif dengan potensial reduksi yang rendah (anoda)

>> Sel Volta dan Elektrolisis
1) Sel volta : mengubah engergi kimia menjadi energi listrik
Katoda sebagai kutub positif, anoda sebagai kutub negatif
2) Sel elektrolisis: : mengubah energi listrik menjadi energi kimia
Katoda sebagai kutub negatif, anoda sebagai kutub positif

>> Jembatan garam (kata bu Via "wajib ada pada sel elektrolisis") memiliki fungsi untuk menetralkan larutan, biasanya berupa agar - agar.

contoh penerapan materi ini dalam kehidupan sehari - hari contohnya adalah batu baterai, aki, dan masih banyak lagi.
I think enough, see you :))
aku berlari di ujung senja
menuju hamparan ilalang yang menjulang tinggi
di atas padang tak berbukit
sekadar melambungkan asa yang telah lama mati
terkulai dalam deburan tanah-tanah hitam
semakin ku menembus tingginya ilalang
yang dengan sombongnya berdiri tanpa malu-malu
tanpa sungkan melambai-lambai
tak mau barang sedetik melangkah memberiku jalan
kakiku tak mampu berhenti
hingga terkulai lemas di penghujung mata air
mendapati diri yang tak lagi mampu berdiri
dengan matahari yang perlahan - lahan redup
seredup pandanganku
menembus dunia kegelapan tiada batas
sayup-sayup hembusan angin
diam - diam meninggalkanku
dalam bisu yang mencekat ulu hati
hingga tak ku dapati suara nyanyian ilalang menyambut
serombongan raja purnama dengan seribu bintang permaisuri
dalam raga yang tak mampu merasa
ku dapati diriku melayang tersapu angin malam
bukan sekadar angin malam,
melainkan sapuan badai biru
yang mendayu - dayu hebat
merobohkan kesombongan ilalang
membabat habis seluruh alam sadarku yang tersisa setitik debu
samar-samar terasa jemari menyambutku
memapah raga hampir tak bernyawa
jika otak masih mampu bekerja
ku rasakan sapuan tipis tangan halus membasuh wajah pucatku
mendekapku hangat, sehangat mentari musim semi
kehangatan yang membawa jiwaku pulang
pada gubuk penantian yang kini menjilma menjadi istana
meninggalkan langkahku pada padang tak berperi
namun masih saja aku ingin kembali
merajut untaian ilalang
manapaki padang di bawah lantunan nada merdu sang bayu
mendengarkan belalang bercerita
tentang sang putri yang menanti pangeran datang menculik, kesekian kalinya
terbalut kedinginan yang memberiku kekuatan
terbaring di atas rumput-rumput tua
yang menjadi teman-teman setiaku
mencari sapuan tangan halus
yang menentramkan jiwa
yang pernah mendekapku dalam keheningan
teruntuk raga yang kian menanti
ku labuhkan pandangan
pada bintang yang bersinar paling terang
yang sorot matanya mampu menembus mata batin
memberikan terang pada jiwa yang pernah mati
karena rasa yang besandar pada satu hati
Setelah menunggu lama, akhirnya kemarin, 11 Juli 2011 pengumuman hasil OSP dapat disimak di salah satu website milik pemerintah.
