Abstract

The furniture industry is experiencing the problem of uncertainty in determining the optimal amount of wood raw material inventory. Fuzzy logic is one of the methods used to analyze systems that contain uncertainty. This study discusses the application of fuzzy logic in solving the problem of supplying wood raw materials in the furniture industry with the Fuzzy-Mamdani approach. The data used in this study are data on the entry, distribution, and supply of wood raw materials from January to December 2018. The design of the system to obtain output is carried out in the following stages: (a) Formation of fuzzy sets, (b) Application of functions implications, (c) Composition of rules, (d) Affirmation (defuzzification). Solving the problem using the Fuzzy Tsukamoto method is carried out by the Tsukamoto method with the help of Visual Basic software so that the desired results will be obtained on the output variable. From the results of calculations using the Fuzzy Tsukamoto method, it can be analyzed that the comparison between the realized wood raw material inventory with the Fuzzy Tsukamoto approach looks different and the results from the Fuzzy Tsukamoto approach are more optimal.

Abstract

Supplier performance appraisal is an important decision in a company, because it will increase the company's competitiveness in the face of highly competitive business competition. PT. JQK is currently selecting suppliers who will supply mahogany wood raw materials with five suppliers, namely Manggala Jati, UD. Jati Mukti, “Mukti” Teak Wood Shop, Gunung Hijau, and Indah Sentosa. In this study, the best supplier performance assessment used the Analytical Hierarchy Process (AHP) method. This method is based on the concept of pairwise comparison for each existing hierarchy in the existing hierarchical structure. The criteria used in this selection are 3 criteria and 6 sub-criteria that support each criterion. The criteria that can be used for supplier performance assessment are time, quality, and price. Sub-criteria that can be used in evaluating supplier performance are on time delivery, lead time, specifications of raw materials, quantity of raw materials, purchase price of raw materials, and transportation costs. Based on calculations using the AHP method, the supplier with the best value is the “Indah Sentosa” supplier, whose value is 0.344 or 34.420%.

Abstract

Salah satu komponen penting dalam suatu proses produksi adalah karyawan. Industri yang maju dengan pesat tidak lain dan tidak bukan berkat adanya kinerja yang baik dari setiap elemen yang ada dalam suatu industri tersebut. Salah satu contoh kinerja dari karyawan yang baik akan berakibat baik pula bagi suatu perusahaan. Kinerja karyawan bagi PT. XYZ merupakan suatu elemen yang penting bagi perusahaan, karena dengan adanya karywan PT. XYZ dapat melakukan proses proses produksi. Saat ini, di perusahaan dalam melakukan penilaian kinerja karyawan masih mengalami kesulitan. Kesulitan terebut terjadi karena belum adanya kriteria yang secara rinci dapat dipergunakan untuk penilaian kinerja karyawan. Sehingga pada penelitian ini akan berusahaan menemukan kriteria-kriteria yang berpengaruh dalam penilaian kinerja karyawan. Pengolahan data pada penelitian ini menggunakan metode Weighted Product (WP). Kriteria yang dapat mempengeruhi kinerja karyawan adalah kedisiplinan, tanggung jawab, ketrampilan, dan komunilasi.

Abstract

An employee performance appraisal process is a set of certain processes which will produce a value from the employee's performance in a certain value, either in percentage or in another unit of value. In an employee appraisal process it will be difficult when the structure of the problem and how to solve it are unknown. Assessing employee performance will be easier if you know the structure of the problem and know how to do it. In this study, we tried to apply the Weighted Product (WP) method in an employee performance appraisal process. The problem of evaluating employee performance can be approached using the Multi Attribute Decision Making (MADM) approach. With this approach, one of the methods that can be used in solving the Multi Attribute Decision Making (MADM) problem is chosen, namely the Weighted Product (WP) Method. The difficulties experienced by a company in carrying out the employee performance appraisal process are due to the absence of certain criteria that can be used in evaluating employee performance. This research seeks to find criteria that can be used in the employee performance appraisal process. In addition, this research will also design a Decision Support System (DSS) that can be used in the process of evaluating the performance of employees in the company. Based on the research that has been done, several criteria are obtained that can be used in the process of assessing employee performance, namely responsibility, discipline, communication and skills and loyalty. In addition, based on the results of system testing that has been done, it can also be concluded that the Decision Support System (DSS) that has been designed can be used as a tool to facilitate the employee performance appraisal process. Keywords: Performance Assessment, WP Method and Decision Support System (DSS) ABSTRAK Suatu proses penilaian kinerja karyawan merupakan suatu kumpulan proses tertentu dimana akan menghasilkan suatu nilai dari kinerja karyawan dalam satau nilai tertentu, baik dalam persentase atau satuan nilai yang lain. Dalam suatu proses penilian karyawan akan menjadi sulit ketika belum diketahui struktur masalahnya dan cara penyelesaiannya. Penilian kinerja karyawan akan lebih mudah jika sudah diketahui struktur masalahnya dan diketahui caranya. Dalam penelitian ini mencoba menerapkan metode Weighted Prodct (WP) di dalam suatu proses mekanisme pemberian nilai kepada karyawan. Masalah pemberian nilai kepada kinerja karyawan berusaha didekati dengan menggunakan pendekatan Multi Attribute Decision Making (MADM). Dengan pendekatan tersebut dipililah salah satu metode yang dapat digunakan dalam penyelesaian permasalahan Multi Attribute Decision Making (MADM) yaitu Metode Weighted Product (WP). Kesulitan yang diamlai oleh suatu perusahaan di dalam melaksanakan proses penilaian kinerja karyawan disebabkan belum adanya atau belum terdapat kriteria acuan yang dapat digunakan dalam melakukan pemberian nilai kinerja karyawan. Dalam penelitian ini berusaha menemukan kriteria-kireria yang dapat digunakan atau dapat difungsikan untuk pemberian nilai kepada kinerja karyawan. Selain itu, dalam penelitian ini juga akan dirancang suatu sistem yang dapat mempercepat pemberian nilai kepada karyawan dalam wujud atau model rancangan yang berupa Sistem Pendukung Keputusan (SPK), dengan harapan proses atau mekanisme pemberian nilai kinerja karyawan dalam berjalan lebih cepat dan tepat. Bedasarkan penelitian yang telah dilakukan diperoleh beberapa kriteria yang dapat difungsikan atau dapat dipergunakan dalam pemberian nilai kepada kinerja karyawan diantaranya yaitu tanggung jawab, kedisiplinan, komunikasi dan keterampilan serta loyalitas. Selain itu, berdasarkan hasil pengujian sistem yang telah dilakukan dapat disimpulkan juga bahwa Sistem Pendukung Keputusan (SPK) yang telah dirancang dapat digunakan sebagai sarana dalam mempermudah proses penilaian kinerja karyawan. Kata Kunci: Pemberian Nilai Kinerja, Weighted Product (WP) dan Sistem Pendukung Keputusan (SPK)
