[ABSTRAK
BULOG mengemban tugas dalam menjamin ketahanan pangan, tugaspubliknya adalah menyalurkan raskin, menyalurkan beras kepada golongananggaran, dan mengelola cadangan beras pemerintah. Penyaluran Beras BULOGsangat bervariasi sesuai jumlah Rumah Tangga Sasaran Penerima Manfaat (RTSPM)dan konsumsi beras per RTS. Selain itu, pengadaan beras dalam negeri jugabervariasi tergantung dari kemampuan penyerapan BULOG akan produksi berasdalam negeri. BULOG bertanggung jawab mengelola stok dan stok penyanggauntuk menjaga tersedianya beras setiap waktu ditengah ketidakpastian penyalurandan pengadaan beras. Pendekatan sistem dinamis dapat digunakan untukmempelajari perilaku sistem BULOG untuk menentukan jumlah stok beras yangoptimal setiap waktu dan agar BULOG dapat mengambil kebijakan yang tepat.Hasil penelitian menunjukkan BULOG sebaiknya memiliki stok penyanggasejumlah 950 ribu-1 juta ton beras per bulan sehingga BULOG memiliki stokakhir minimal berjumlah 1.33-1.58 juta ton beras per bulan pada tahun 2014-2017. Kebijakan ketahanan stok bernilai tiga bulan dan dengan kebijakan tersebutstok nasional dan stok divisi regional BULOG di seluruh Indonesia tidakmengalami kehabisan stok (stock-out).

ABSTRACT
BULOG has task in ensuring food security, its public duties is channelingRaskin, distributing rice to budget class, and managing the government's ricereserves. BULOG rice distribution varies according to the number of BeneficiariesTargeted Households (RTS-PM) and the consumption of rice per RTS. Inaddition, the domestic rice procurement also varies depending on the BULOG?sabsorption capacity of the rice production in the country. BULOG is responsiblefor managing stock and bufferstock to maintain the availability of rice every timeamid uncertainty of distribution and procurement of rice. SystemDynamicsapproach can be used to study the behavior of the BULOG?s system todetermine the optimal number of stocks of rice every time therefore BULOG cantake the right policy. The results showed BULOG should have a buffer stock of950 thousand to 1 million tons of rice per month so BULOG has minimum stockof 1.33 until 1.58 million tons of rice per month in the year 2014-2017. Minimumstock requirement is worth three months and with that policy, the national stockand BULOG regional divisions stock across Indonesia had not run out of stock.;BULOG has task in ensuring food security, its public duties is channelingRaskin, distributing rice to budget class, and managing the government's ricereserves.
