Karya Ilmiah Potensi Kulit Jeruk dijadikan sebagai Alternatif Pengganti Bahan Bakar Fosil


BAB I
PENDAHULUAN

1.1    Latar Belakang
Hampir semua orang mengenal tanaman jeruk, terutama bagian buahnya yang sangat digemari. Tanaman jeruk ini semula hanya berupa vegetasi alami yang menempati areal yang cukup luas di Asia Timur dan Asia Selatan mulai dari Cina sampai India, Malaysia, Indonesia, Filipina dan Kaledonia Baru. Namun saat ini  tanaman tersebut telah dibudidayakan di hampir semua negara tropis dan sub tropis.
Tanaman jeruk ini tidak hanya disukai oleh masyarakat karena rasa buahnya yang segar dan manis namun tanaman ini mempunyai begitu banyak manfaat antara lain beberapa produk makanan yang dibuat dari jeruk, misalnya kulit buah untuk selai dan permen. Pektin dibuat juga dari kulit buah jeruk dan asam sitrat dari jeruk lemon dan jeruk nipis. Bunga, buah dan daun jeruk yang harum itu di ekstrak menjadi minyak atsiri. Kulit buahnya merupakan sumber yang baik, tetapi hanya bunga jeruk asam yang menghasilkan wewangian yang paling mahal.
Di Indonesia sendiri jeruk merupakan komoditas buah-buahan terpenting setelah pisang dan mangga. Produksi jeruk di Indonesia pada tahun 2001 mencapai 744.052 ton/tahun. Bila kebutuhan konsumsi buah jeruk segar diasumsikan 3,26 kg/kapita/tahun atau 30 buah/kapita/tahun, maka dengan perhitungan jumlah penduduk 204,4 juta jiwa memerlukan ketersediaan buah jeruk segar sebanyak 866.247 ton. Data tahun 2001 menunjukkan bahwa Indonesia mengimpor jeruk sebesar 73.304 ton, sehingga total ketersediaan mencapai jumlah 817.356 ton (Dirjenhorti; 2002).
Melihat kebutuhan akan tanaman jeruk cukup tinggi baik karena kandungan gizinya maupun manfaat lain yang bisa diambil, maka penulis ingin mencoba menggali potensi lain dari buah jeruk yang sebenarnya hampir terlupakan oleh kita, yaitu  pemanfaatan kulit jeruk. Baca pos ini lebih lanjut

PEMBUATAN BAKSO IKAN KURISI (Nemiterus nemata) DENGAN PENAMBAHAN KARAGENAN DAN CHITOSAN


I. PENDAHULUAN

1.1 Latar Belakang

Sebagai negara maritim yang memiliki perairan yang luas konsumsi ikan indonesia sangat memprihatinkan. Hingga Desember 2003 tingkat konsumsi ikan per orang di Indonesia rata-rata 24,67 kilogram per tahun. Volume itu tergolong jauh lebih rendah dibanding dengan konsumsi ikan di Korsel dan Jepang yang rata-rata di atas 100 kg per orang per tahun atau Thailand yang mencapai 35 kg per orang per tahun.(kompas.com, 2007)

Salah satu cara yang bisa ditempuh untuk meningkatkan konsumsi ikan adalah dengan diversifikasi produk hasil perikanan. Salah satu produk yang diharapkan bisa memberikan penetrasi pasar adalah produk bakso ikan diakarenakan kebudayaan masyarakat Indonesia yang sangat menyukai bakso.

Bakso ikan didefinisikan sebagai produk makanan berbentuk bulatan atau lain, yang diperoleh dari campuran daging ikan (kadar daging ikan tidak kurang dari 50%) dan pati atau serealia dengan penambahan atau makanan yang di inzinkan ( Nurfianti, 2007). Baca pos ini lebih lanjut

Everybody should change their way of life to reduce global warming. There are several things that we can do. One of them is by buying and consuming fresh local groceries as much as possible. It of course includes local vegetables, fruits, bread, etc.

Arguement 1

Local groceries don’t need much transportation to get it into the market. It of course means, the amount of carbon dioxide produced is less than the groceries from other region. Therefore, by buying local groceries we are helping reduce the amount of carbon dioxide produced.

People Should Use Trans Jakarta Bus


Thesis

As we know that the status quo right now in Jakarta, many people have personal car. Because of that, Jakarta always have traffic jam, not only in the morning, but also in the evening everyday. It’s very big problem in Jakarta. So, the government makes some ways to solve this problem. One of the ways, they make Trans Jakarta bus which is having a specific line.

Argument 1

People should use the Trans Jakarta bus. Why? Because it can make many advantages for the people who doesn’t have vehicles. In the other hands, it can influence the condition in Jakarta. which mean that, Trans Jakarta can change the situation in Jakarta which before have many traffic jam in everywhere, become fluent on the way

The second argument of this text, if the people use the Trans Jakarta bus, they will thrifty the money, because they just cost 3500 rupiahs and they can transit to other place without pay again. And then they don’t have to fill the car with gas, which is more expensive than use Trans Jakarta.

Third, if all of the people use Trans Jakarta bus, it will also decrease the polution in Jakarta, because the people always drive their car and ride their motorcycle are decreasing so that the polution will also decrease.

Fourth, when the people has already use the Trans Jakarta bus, it makes the cars and motorcycles in the road decrease, the road will little bit empty and so the Trans Jakarta bus can pass by without the resistor.

Finally, come to my last argument, if the people use Trans Jakarta bus, they will feel more comfort then they use public transportation, motorcycles, and etc. Because the Trans Jakara bus uses air conditioner can fill a lot of people. And if we use the ordinary bus like Kopaja, Metro Mini, bemo, and etc, there a lot of criminals, but not in the Trans Jakarta bus because there is a guard.

So, the conclusion of this text is the Trans Jakarta bus giving us some advantages such as cheap, comfortable, avoid from polution, and avoid from criminality, and make the air of Jakarta is getting better and fresher. And finally, using the Trans Jakarta bus will change the Jakarta’s condition. Which full of cars before become fluent and less the fluel using.

So, we believe that people should use the Trans Jakarta bus to change our Jakarta become comfort city.
