  • Properti Eigen Untuk Graf k-Regular Tak Terhubung

    • Authors: R. Respitawulan
      Abstract: Abstract. (eigen properties of non-connected k-regular graph) One of the important properties of an adjacency matrix as a representation of a graph is its eigen property. According to Biggs, a k-regular connected graph will have k as one of its Eigen value and the multiplicity is 1. Here, we investigate the Eigen value and its multiplicity of a non-connected
      k-regular graph. The result shows if a non-connected k-regular graph has c components, then will be one of its eigen value with the geometric multiplicity of c.Keywords: adjacency matrix, eigen values, geometric multiplicityAbstrak. Salah satu sifat penting dari matriks adjasen sebagai representasi dari graf adalah sifat eigennya. Biggs menyatakan bahwa graf regular terhubung dengan derajat k akan memiliki nilai eigen k yang multiplisitasnya satu. Di sini diselidiki nilai eigen untuk graf k-regular yang tak terhubung. Jika graf k-regular tak terhubung memiliki c buah komponen, maka k akan menjadi salah satu nilai eigen graf tersebut dengan multiplisitas geometri c.Kata kunci: matriks adjasen, nilai eigen, multiplisitas geometri

  • Pemeringkatan Pegawai Berprestasi Menggunakan Metode AHP (Analytic
           Hierarchy Process) di PT. XYZ

    • Authors: Andri Suryadi, Erwin Harahap
      Abstract: Untuk mendapatkan pegawai terbaik perlu adanya pemeringkatan berdasarkan kriteria yang telah ditetapkan oleh PT XYZ. Salah satu kriteria yang dimaksud adalah kemampuan hard-skills dan soft-skills. Namun, dengan adanya kategori tersebut menjadi sulit bagi pimpinan perusahaan untuk mendapatkan keputusan yang terbaik terutama dalam relasi antar kategori yaitu kolaborasi hard-skills dan soft-skills. Oleh karena itu dibutuhkan suatu metode untuk dapat memeringkatkan pegawai berprestasi sehingga dapat memudahkan pimpinan dalam pemilihan tersebut. Analytic Hierarchy Process (AHP) merupakan metode yang dapat menyelesaikan masalah pengambilan keputusan berdasarkan banyak kategori. Kemampuan hard-skills dan soft-skills dapat dikolaborasikan menggunakan AHP sehingga keterkaitan antara kategori menjadikan proses pemilihan pegawai berprestasi menjadi mudah.Kata kunci: pegawai berprestasi, hard-skills, soft-skills, AHP, analytic hierarchy process.abstract in English:Ranking of High-Performance Employees Using the AHP (Analytic Hierarchy Process) Method at PT XYZTo get the best employees need to rank based on the criteria set by PT XYZ. One of the criteria in question is the ability of hard-skills and soft-skills. However, with the category, it becomes difficult for the leadership of the company to get the best decision especially in the relationships between categories of collaboration hard-skills and soft-skills. Therefore, it is necessary a method to be able to improve employee achievement to facilitate the leadership in the election. Analytic Hierarchy Process (AHP) is a method that can solve the problem of decision making based on many categories. The ability of hard-skills and soft-skills can be collaborated using AHP so that the interrelationship between the categories makes the eligible employee selection process easy.Keywords: employee achievement, hard-skills, soft-skills, AHP, analytic hierarchy process.

  • Pengendalian Persediaan Produksi Hijab Berdasarkan Economic Production
           Quantity di RAR Azkia

    • Authors: Farid H Badruzzaman, Erwin Harahap, Eti Kurniati, M. Deni Johansyah
      Abstract: Abstrak. Permasalahan dari persediaan adalah bagaimana menentukan jumlah produksi optimal dengan biaya total persediaan yang minimum. Sebuah persediaan dilakukan tidak lain dengan maksud mengantisipasi dan memenuhi permintaan yang akan datang. Penyimpanan persediaan dalam jangka waktu yang lama akan berdampak pada keusangan dan menurunnya kualitas, sehingga diperlukan perhitungan jumlah persediaan yang optimal. Model persediaan Economic Production Quantity (EPQ) merupakan suatu metode yang digunakan untuk mempertimbangkan jumlah produksi dan jumlah permintaan hasil produksi. Tujuannya adalah dengan menentukan banyaknya produksi yang meminimumkan total biaya persediaan. Penelitian ini bertujuan untuk menghitung jumlah produksi optimum pada perusahaan kerudung. Selama ini, jumlah produksi pada tahun 2017 dan sebelumnya berpedoman pada jumlah pesanan pelanggan ditambah 17,5% dari jumlah permintaan untuk cadangan persediaan. Hasil solusi optimum dengan model EPQ memiliki perbedaan yang signifikan dibandingkan dengan yang selama ini berlaku.
      Kata Kunci: economic production quantity, persediaan, produksi
      Abstract. The problem of inventory is how to determine the optimal amount of production with minimum total inventory cost. An inventory is carried out with no other intent to anticipate and meet future demand. Storage of inventory over a long period of time will have an impact on obsolescence and declining quality, so it is necessary to calculate the optimal amount of inventory. Model inventory Economic Production Quantity (EPQ) is a method used to consider the number of production and the number of production demand. The goal is to determine the amount of production that minimizes the total cost of inventory. This study aims to calculate the number of optimum production on the company's hood. So far, the number of production in 2017 and previously guided by the number of customer orders plus 17.5% of the total demand for inventory reserves. The results of the optimum solution with the EPQ model have significant differences compared to those currently in force.

  • Efektifitas Load Balancing Dalam Mengatasi Kemacetan Lalu Lintas

    • Authors: Erwin Harahap, Andri Suryadi, R Ridwan, Deni Darmawan, Rakhmat Ceha
      Abstract: Abstrak. Kemacetan jalan raya merupakan permasalahan umum di setiap kota yang memerlukan penanganan serius. Pemecahan permasalahan kemacetan jalan raya tidak hanya dapat diselesaikan dengan hanya meningkatkan kualitas dan kuantitas infrastruktur, namun juga manajemen lalu lintas. Pada artikel diusulkan suatu metode untuk mengurangi kemacetan lalu lintas, yaitu dengan menyeimbangkan beban ke berbagai ruas jalan yang disebut dengan load balancing. Melalui metode ini diharapkan beban lalu lintas terbagi secara merata ke berbagai jalur alternatif sedemikian sehingga antrian panjang kendaraan dapat dihindari. Evaluasi efektifitas dari metode load balancing ini dilakukan melalui simulasi dengan mengimplementasikan salah satu bidang ilmu Matematika, yaitu teori Antrian. Simulasi dibuat dengan menggunakan toolbox SimEvents yang dijalankan pada software MATLAB.Kata Kunci: load balancing, kemacetan, lalu lintas, sim-events, matlabAbstract. (the effectiveness of load balancing in reducing the road traffic congestion) Road congestion is a common problem in any city that needs serious handling. The solution of the road congestion problems can not only be solved by simply improving the quality and quantity of infrastructure, but also the traffic management. In this article, we proposed a method to reduce the traffic congestion by balancing the vehicle loads to a various road segments, called as load balancing. Through this method, it is expected that the traffic load is evenly distributed to various alternative routes, such that, long queues and traffic jam can be avoided. Evaluation of the load balancing’s effectiveness is performed through a simulation by implementing the Queueing Theory. Simulations are created using the SimEvents toolbox that runs on MATLAB software.Keywords: load balancing, road congestion, traffic, simevents, matlab.
