Abstract

Salak dan carica merupakan hasil pertanian holtikultura unggulan Kabupaten Banjarnegara. Harga salak tidak stabil sepanjang tahun. Industri pengolahan salyca (salak dan carica) dibutuhkan untuk mengurangi fluktuasi harga salak dan mengoptimalkan potensi carica di Kabupaten Banjarnegara. Salyca dalam sirup belum pernah dianalisa dan diproduksi. Penelitian bertujuan mengetahui kelayakan teknis, pasar dan finansial pengolahan salyca dalam sirup skala Industri Mikro Kecil di Kabupaten Banjarnegara. Kelayakan teknis menganalisa teknologi proses pengolahan, investasi peralatan, kebutuhan bahan baku, dan tenaga kerja. Kelayakan pasar menganalisa kebutuhan konsumen. Kelayakan finansial dengan metode analisis sensitivitas, manfaat dan biaya bertujuan mengetahui laba rugi, aliran kas, Net Present Value (NPV), Internal Rate of Return (IRR), Pay Back Period (PBP) dan Profitability Index (PI) dengan perubahan kapasitas bahan baku. Analisa menunjukkan usaha layak secara pasar, finansial dan teknis. Kelayakan aspek pasar ditunjukkan oleh 72% dari 99 responden, lebih menyukai produk salyca dalam sirup dan 28% responden lebih menyukai salak dalam sirup. Responden memilih produk dikemas dalam cup plastik dan dapat dibeli di mini market, tempat wisata dan toko oleh–oleh. Kelayakan finansial diperoleh pada kapasitas minimum bahan baku 18 Kg perhari. Kelayakan teknis ditunjukkan pada ketersediaan bahan baku. Kapasitas bahan baku dan tenaga kerja meningkat bertahap selama tiga tahun pertama.

Abstract

Project scheduling is essential to be planned before activities. Standard methods of project scheduling based on precedence constraints scheduling events and the assumption that resources are not unlimited capacity. But in fact the project activity has resource limits. The main objective is to minimize the total duration of the project with precedence constraints and resource constraints for all project activities. Many optimization methods are used to improve the quality of scheduling and speed up the calculation time. This paper proposed the use of Cross Entropy (CE) method to solve resource constraints project scheduling problem, as well as comparing the advantages and disadvantages between the CE methods with Differential Evolution (DE) method. The purpose CE method consist of four critical steps including generating a sample of random solution, calculating the performance according to the specific fitness function, selecting elite sample and finally updating the previous parameters to get a better sample in the next iteration. To speed up the computation time, in this study decrease the number of samples for each iteration in Cross Entropy algorithm. Numerical experiments with several data sets from the Project Scheduling library (PSPLIB) showed that CE can provide the optimal total duration of the project same as the DE with calculation time is faster than DE.
