The Increassing program in national corn production has been achieved by the government through special efforts over the past 2 years (2016-2017). This success is marked by the closure of import faucets in 2017. Furthermore, government policies are directed at the development of functional corn or corn which has bioactive content that is beneficial to human health. Madura Island has a vast area of corn plantations.

The growth of small-medium business enterprise in Indonesia is getting faster in decade, including small-medium business enterprise who produce slippers. SISCO is one of small-medium business enterprise who produce slipper. They must keep tight with market requirement. The supply of raw materials in a small-medium business enterprise is one of the important during production process. In some case their products are mismatch number from market demand. It can be worse if there a mismatch between raw materials ordering schedule from supplier and market demand from consumers. One of this problem requires Economic Order Quantity method as a solution, because during slippers production we have to order from supplier. Inventories are materials stored as raw materials, then they processed be finish product. To find out inventory, one of the inventory models used is the economic order quantity model. This method seeks to achieve the minimum possibility of inventory levels and lower costs and better quality. Economic Order Quantity method calculation based on raw material inventory control in SISCO slipper brand. Optimum monthly cost is IDR 5.293.541,03 to meet supply materials.

Meningkatnya pertumbuhan populasi sangat berpengaruh besar terhadap aspek permintaan suatu produk dan menyebakan tekanan secara eksponensial dari sumber daya alam yang digunakan. kisaran konsumsi minyak di Indonesia yaitu berada pada 1.398.496 (barel/day.th) sampai 1.611.599 (barel/day.th), dimana Indonesia termasuk kedalam 10 besar negara dengan penggunaan terbanyak. menciptakan produk alternative yang memiliki kualitas baik , mendaur ulang limbah sebagai bahan baku, atau peningkatan teknologi yang mengurangi jumlah input,serta startegi pemasaran yang tepat dalam pengenalan produk baru atau produk inovatif. Salah satu energi alternatif yaitu bio-oil. Pemasaran bio-oil masih terbatas dan sangat kurang khususnya di kabupaten sumenep. Hal ini banyaknya masyarakat yang belum mengetahui bio-oil dan juga belum memahami pentingnya energi terbarukan sebagai perngganti energi dari bahan bakar fosil. Pada penelitian ini strategi pemasaran bio-oil dilakukan dengan menggunakan analisis SWOT (Strengths Weakness Opportunities Threats), strategi yang tepat digunakan adalah agresif (growth oriented strategy) dimana mengembangkan kekuatan dari faktor internal(s-w/2=0,24; o-t/2=0,39) dan peluang dari faktor eksternal serta penggunaan matriks QSPM, penetrasi pasar (Tas=6,84) menjadi pilihan utama untuk memaksimalkan strategi yang diterapkan

GiliLabak Island is one of the Madura's remote islands, actually has the opportunity of utilization of renewable energy source that is available abundantly throughout the year such as solar and wind energy. The utilization of both alternatives energy need feasibility analysis. First stepis collecting datas of electricity daily energy demand inGiliLabak which was gotten aproximatly 61.870 Kwh/day. The next process performs an economical analysis for each type of solar cell package as the most economical option based on NPV and IRR analysis. After knowing the energy generated by each wind power package then will calculate how much wind power system's needed for all the electricity demand. To find out how many wind power plants (wind power plants) then the energy generated for one year/energy that will be generated from each hydropower package. Finally step was doing comparison of both two alternatives energy which the most economist. Based on economic analysis with NPV and IRR approach from several alternative power plants from solar cell and wind turbine can be concluded that alternative solar cell type 1000 Wp polycrytaline is a very feasible alternative to be realized because it has a value of NPV>0 while from the value of IRR-27% is the highest of all alternatives that have IRR value above the discount factor value (14%).
