"[Penelitian ini bertujuan untuk mengevaluasi jaringan sistem distribusi eksisting pupuk urea bersubsidi PT X, khususnya antara gudang distributor dan gudang pengecer. Pada penelitian ini dilakukan optimasi jaringan eksisting dengan menggunakan beberapa skenario untuk memperkuat analisa dengan didasarkan pada model minimum cost flow, dengan tujuan untuk meminimasi biaya transportasi di dalam jaringan. Berdasarkan optimasi dengan beberapa skenario didapat efisiensi biaya distribusi sebesar 61% s/d 89% terhadap eksisting. Apabila biaya satuan transportasi prediksi bias +20% maka efisiensi biaya distribusi menjadi 70% s/d 106% terhadap biaya eksisting, sedangkan apabila biaya satuan prediksi bias -20% maka efisiensi biaya distribusi menjadi 51% s/d 71% terhadap biaya eksisting. Berdasarkan hasil optimasi ini terlihat bahwa kondisi jaringan sistem distribusi eksisting masih dapat diperbaiki dengan melakukan restrukturisasi rayonisasi gudang pengecer., This study aims to evaluate the distribution system of existing networks of subsidized urea fertilizer in PT X particularly between distributor warehouses and kiosk ones. In this study, the optimization of existing networks is carried out by using several skenarios to strengthen the analysis and it is based on minimum cost flow model which is aimed to minimize transportation costs of the networks. The optimization finds cost efficiency about 61% up to 89% of the existing costs. When the predicted unit cost is biased +20% thus the cost efficiency be 70% up to 106% of the existing costs. On the other hand, when the predicted unit cost is biased -20% thus the cost efficiency be 51% up to 71% of the existing costs. From the optimization is shown that the current system still could be improved by restructuring the clustering system of kiosks of the existing networks.]"

"Mengambil keputusan investasi proyek yang keliru maka tidak dapat direvisi begitu saja, tanpa harus menderita suatu kerugian. Keputusan investasi bagi seorang investor menyangkut masa yang akan datang mengandung ketidakpastian, yang berarti mengandung unsur risiko bagi investor. Umumnya risiko selalu terdapat pada setiap alternatif investasi, tetapi besar kecilnya risiko tersebut tergantung pada jenis investasinya.Sebelum mengambil keputusan jadi tidaknya suatu investasi, salah satu syarat yang terpenting adalah mengkaji aspek finansial dan ekonomi. Dari segi financial mutu rencana pembangunan proyek di ukur dari kemampuan proyek itu memenuhi kewajiban finansialnya (biaya modal) dan menghasilkan keuntungan yang memadai. Disinilah letaknya keterkaitan antara keputusan investasi dan pendanaan. Karena dilihat dari segi dunia usaha, proyek hanya akan dilakukan apabila memenuhi salah satu syarat penting, yaitu tingkat keuntungan melebihi biaya modal (cost of capital-COC).Penelitian ini bertujuan mengetahui kelayakan pembangunan proyek MTH tower dari aspek finansial dan pendanaan, terhadap risiko perubahan inflasi, tingkat suku bunga, dan pertumbuhan ekonomi dengan simulasi monte carlo. Dari proses analisa dihasilkan nilai NPV yang bisa dikatakan layak, apabila menggunakan harga jual sebesar Rp9,960,000/m² dan nilai yield sebesar13.2%, serta memberikan tingkat keyakinan yang paling besar untuk proyek MTH Tower mendapatkan proyek yang bersifat layak adalah pada alternatif pertama dengan jumlah sebesar 42.94%
