Abstract

This paper will show the completion of PDAM data by determining the shortest pipe length from PDAM data, in other words finding the shortest pipe length from the tree model that is formed. In this PDAM pipe network problem, the distance from each pipe is determined from one area to another. In this study, each PDAM pipe has a different distance between one pipe and another. So with this problem we need a way to determine the shortest pipe length from each PDAM pipe between regions. By determining the length of the shortest pipe so that the shortest distance can be obtained from the use of the pipe. After obtaining the shortest distance, this research will be able to obtain a model in the form of a graph, namely Tree and will look for the shortest pipe length between one area and another for the PDAM pipeline network in the city of Padang. In this case, Padang Timur was chosen as the object of research because of the ineffective use of the PDAM pipe network. The region using the Graph method is expected to be able to determine the shortest pipe length using a pipe network so that it will be more economical and practical to implement.

Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) memiliki peran penting dalam perekonomian global dengan memajukan pertumbuhan ekonomi lokal dan menciptakan lapangan kerja. Di tengah persaingan yang semakin ketat, UMKM perlu mengadopsi strategi efektif untuk meningkatkan produktivitas dan daya saing. Nikyta Seprai adalah sebuah UMKM di sektor tekstil di Kota Padang Panjang yang menghadapi tantangan dalam menentukan kombinasi produksi seprai yang optimal. Untuk mengatasi tantangan tersebut, metode optimasi, khususnya Integer Linear Programming, sangat penting untuk meminimalkan biaya bahan baku dan memaksimalkan keuntungan. Metode Simpleks dan metode Branch and Bound menawarkan pendekatan yang menjanjikan untuk mengoptimalkan produksi seprai di Nikyta Seprai. Artikel ini mengeksplorasi penerapan metode-metode tersebut di Nikyta Seprai, mengidentifikasi tantangan dalam proses produksi, dan mendemonstrasikan bagaimana metode optimasi dapat mengatasi tantangan tersebut, menghasilkan efisiensi produksi yang lebih baik dan keuntungan maksimum. Hasil analisis menunjukkan bahwa masalah penentuan kombinasi produksi seprai dan alokasi sumber daya untuk mendapatkan keuntungan maksimum di Nikyta Seprai yang diselesaikan menggunakan Integer Linear Programming, khususnya melalui metode Simpleks dan metode Branch and Bound. Solusi optimal menghasilkan keuntungan sebesar Rp 842.500, dengan jumlah produksi seprai karet sebanyak 10 buah, seprai rimpel sebanyak 1 buah, dan seprai 2 in 1 karet sebanyak 1 buah, dengan menggunakan software POM-QM V5.
