[Target swasembada jagung di tahun 2016 perlu untuk dikaji ulang ketercapaiannya, karena target tersebut diiringi dengan beberapa kebijakan lainnya, seperti : penahanan stok di pelabuhan, pencabutan lisensi impor jagung oleh swasta, pemusatan manajemen stok jagung kepada Bulog. Apabila kebijakan-kebijakan tersebut tetap diimplementasikan di tengah kondisi pasar domestik yang kekurangan suplai, maka target swasembada jagung tahun 2016 akan menjadi malapetaka bagi para produsen pakan ternak yang memerlukan suplai jagung secara teratur. Studi ini ditujukan untuk meramal pencapaian target swasembada jagung di tahun 2016 dengan cara meramal produksi dan konsumsi pada tahun 2016 menggunakan beberapa alternatif metode : OLS, ARIMA, Time Trend Variable dan Recursive Model. Hasilnya, Indonesia akan mencapai swasembada jagung pada tahun 2016 dengan surplus sebesar 189.918 ton jagung pipilan kering dengan kadar air 25%. Namun mengingat kebutuhan industri pakan yang merupakan jagung pipilan kering dengan kadar air 15%, maka volume produksi yang menyusut akan membuat perhitungan di tahun 2016 malah menjadi defisit sebesar 2,51 juta ton. Apabila Indonesia ingin menutup defisit tersebut, diperlukan lahan jagung sebesar 4,3 juta hektar atau produktifitas lahan sebesar 63 kuintal per hektar. ......Corn self-sufficiency target in 2016 feasibility needs to be revisited because the program brings along several policies, such as : stock restricting at the ports, private’s import license abolishing and centering stock management to Bulog. Unless the domestic market being surplus, the policies implemented will cause a menace for livestock feed producers—for they need a regular corn supply. This study aims to forecast whether the target is going to be achieved by forecasting corn production and consumption in 2016 using several methods : OLS, ARIMA, Time Trend Variable and Recursive Model. The result shows that Indonesia is forecasted to achieve corn self-sufficiency by 2016; shown by a surplus of 189.918 tonne (with 25% moisture content). However, it is should be considered that feed-mill industry needs corn with 15% moisture content—and drying the corn shrinks its mass; leading to decrease of surplus and even change it into deficit of 2.51 million tonne. If Indonesia aims to self-suffice the deficit, then Indonesia needs 4.3 million hectares of corn land or land productivity of 6.3 tonne per hectare. ;Corn self-sufficiency target in 2016 feasibility needs to be revisited because the program brings along several policies, such as : stock restricting at the ports, private’s import license abolishing and centering stock management to Bulog.

In this reform era; government determines a new policy in developing each region. Every regional government now has its own autonomy in planning, funding and allocating its profit, which is gained by itself. It is a great opportunity to all regions, which have rich natural resources. The fact above motivates us to develop a new business, which use natural resources to take a profit, like in agribusiness. We consider that Kabupaten Cirebon fits our criterion, because ( 1 ) its location is not far from Jakarta, (2) we have known this region since six years ago and (3 ) it has quite rich of natural resources. In implementing our aim, we establish a new company in the form of ?Perseroan Terbatas? (Limited Company - abbreviated as ?PT?), which is named PT Margo Karya Dipa. We make a comprehensive business plan to accommodate and to facilitate our aim to be true. In this comprehensive business plan, we can know the characteristic of agrìbusiness like competition, market and prospect rate of return. We hope that this business plan can help our company to grow and give us profitable return. As a start-up, Margo will explore hybrid corn plantation. In the future, Margo will develop its business through another commodity in agribusiness and also in another sector like financial sector, animal husbandry and other investment in natural resources.

ABSTRACT
Label time-temperature indicator TTI telah banyak diteliti dan sebagian telah dimanfaatkan secara komersil karena mampu memberikan informasi perubahan warna akibat paparan suhu selama periode waktu tertentu. Informasi kondisi suatu produk dapat diketahui dengan cepat melalui perubahan warna yang dapat diamati, selain itu riwayat produk juga dapat diketahui karena label TTI bersifat irreversibel, sehingga mempercepat konsumen dalam membuat keputusan terkait pembelian produk tersebut. Label TTI telah banyak memanfaatkan bahan alam yang mengandung antosianin sebagai zat warna karena antosianin memiliki rentang perubahan warna yang luas pada spektrum cahaya tampak. Ekstrak zat warna dari alam dipilih sebagai bahan sensor indikasi temperatur karena aman digunakan pada kemasan produk pangan. Ekstrak dari jagung hitam diteliti sebagai kebaruan bahan label TTI, yang diimobilisasi pada matriks dari chitosan dengan perbandingan 1:3 ekstrak:matriks agar ekstrak dapat menjadi label film. Selain itu, matriks juga diberi tambahan plasticizer gliserol dan glutaraldehyde 1 untuk meningkatkan sifat mekanisnya. Hasil pengkondisian pH dan pengukuran spektrum absorbansi ekstrak jagung hitam pH 2-13 menunjukkan bahwa ekstrak memiliki rentang perubahan warna dari merah pH 2 ke kuning pH 13. Kestabilan ekstrak paling tinggi terjadi pada pH 2 sehingga eksperimen dilakukan di pH 2. Hasil uji perubahan warna label terhadap temperatur menunjukkan label berubah warna dari ungu ke biru ke kuning, dengan perubahan warna paling cepat terjadi pada suhu tinggi 40 oC dan paling lambat terjadi pada suhu rendah 25 oC. Label dari ekstrak jagung hitam berfungsi dengan lebih optimal pada RH ruang dibandingkan pada kondisi RH 33. Selanjutnya, uji reversibilitas memperlihatkan bahwa label dari ekstrak jagung hitam bersifat irreversibel yang merupakan salah satu syarat label untuk menjadi time temperature indicator. Penelitian ini berpotensi untuk dikembangkan secara komersil yaitu pada kemasan produk pangan.

ABSTRACT
Time temperature indicator TTI labels have been widely researched and some have been commercially exploited because they provide color change information due to exposure to temperature over a period of time. Information on the condition of a product can be known quickly through color changes that can be observed directly. In addition, the product history can also be known because the TTI label is irreversible, thus helping consumers in making quicker decisions to purchase such products. Most TTI labels nowadays are utilizing natural ingredients that contain anthocyanins as dyes due to its wide range of colors in the visible light spectrum. Extracts from nature was chosen as temperature sensing indication material because most of them are food grade, safe to use on food product packaging. In this study, extract from black corn was examined as a novelty of TTI label material which was immobilized with a matrix made of chitosan with a ratio of matrix to extract was 1 3, to turn the extract into a film label. In addition, plasticizers of glycerol and glutaraldehyde 1 were also mixed to the matrix to improve its mechanical properties. The results of pH conditioning and absorbance spectra measurement of black corn for pH 2 13 showed that the extract had a color range from red pH 2 to yellow pH 13. The highest extract stability occurred at pH 2 so that the experiment was done in this pH value. The experiment results of the label color change due to temperature show that the labels change color from purple to blue to yellow, with the fastest color changes occurred at high temperatures 40 C and the slowest occurred at low temperatures 25 C. Labels from black corn extract functioned more optimally in room RH compared to RH of 33 . Furthermore, the reversibility test shows that the label from black corn extract is irreversible which is one of the conditions for a label to be a time temperature indicator. This research has the potential to be developed commercially, for example as food product packaging.
