Abstract

AbstrakPT.HH adalah salah satu perusahaan manufaktur yang bergerak dalam bidang produksi baterai dengan orientasi pasar ekspor dan untuk konsumsi dalam negeri. Untuk memenuhi jadwal produksi yang telah direncanakan, salah satu cara yang dapat diandalkan adalah menyeimbangkan lini produksi yang ada agar tidak terlalu banyak waktu longgar. Ada 11 tahapan lini produksi yang akan kita bahas disini, antara lain : Katoda Baterai, Anoda Baterai, Zinc Can, PVC, Carbon Rod, Larutan Elektrolit, Body Metal Jacket, Bottom Plate, Metal Top, Sedling, Crimping. Awalnya ada 35 lini produksi yang terdapat pada pabrik tersebut. Tag Time yang kita dapat dari perhitungan awal adalah 13.68 menit/unit. Jumah waktu mengganggur awalnya adalah 96.95 menit dengan SI 0.725. lalu keseimbangan waktu mengganggurnya adalah 20.249% dengan efesiensi lintasan awalnya adalah  79.751%.  Lalu setelah diterapkan metode Ranked Positional Weight maka didapat nilai SI nya adalah 0.690 dengan jumlah waktu mengganggur adalah 68.370 menit dan keseimbangan waktu mengganggur nya 16.659% dengan  efesiensi lintasannya menjadi 83.341%.   Kata kunci : Lini Produksi,  Tag Time, Efesiensi Lintasan, Ranked Positional Weight.

bstrakPT.ABC adalah perusahaan yang bergerak dalam bidang supply chain management patner. Didirikan pada tahun 2002 dengan kantor pusat di Tangerang dan memiliki beberapa lokasiwarehouse di sekitar daerah operasi customer-nya. Salah satu pelayanannya adalah pengadaancorrugated carton box untuk penyediaan packaging. Penyediaan kertas brown kraft liner sebagaibahan baku utama diambil dari beberapa supplier. Selama ini perusahaan tidak mempunyai kriteriadalam melakukan penilaian supplier, maka untuk mengatasi permasalahan tersebut digunakanmetode ANP (Analytical Network Process) dan TOPSIS (Technique For Order Preference BySimilarity To Ideal Solution) dalam penelitian ini. Metode ANP digunakan untuk pembobotankriteria-kriteria yang mempengaruhi penilaian pemasok dan TOPSIS digunakan untuk memberikanperingkat kepada setiap pemasok. Data yang digunakan adalah data pembeliaan dan penerimaankertas brown kraft liner selama 6 bulan dari 5 pemasok.Kata kunci : ANP, TOPSIS, Brown kraft liner, pemilihan pemasok

Abstract

ABSTRACTThe objective of this research is to predict return of investment in equitysecurities. Investors have primarily objective to increase return from theirinvestment. Investors buy stock from public enterprise and may get dividend orcapital gain as its return.Focus on dividend as its return, this research was conducted to examine theeffect of variable Current Ratio (CURR), debt to equity ratio (DER), and Return onEquity (ROE) toward Dividend Per Share (DPS), in manufacturing companies thatlisted in Indonesia Stock Exchange.The data in this study were taken from the financial statements of companiesmanufacturing in Indonesia Stock Exchanges in the period study was fromDecember 31, 2008 until December 31, 2010. To Obtain financial statements fromeach company, the researcher got in from www.idx.co.id, to see the companiesincluded into the manufacturing industry seen form www.duniainvestasi.com, and tosee company paying the dividends in cash, the researchers see it fromwww.ksie.com. The samples and data are collected using purposive samplingmethod.Hypothesis test of this research using Panel Least Square (PLS). regressionresult shows that three independent variables used may affect dependent variablesas much as 94,7% and the rest which is 5,3% explained by other variables that notbeing used in this research model. Result of simultaneous test shows that threeindependent variables together can explain amount of DPS.Conclusion of this research is the results of this research with significant level5% also indicate that ROE has significantly affect on the DPS. While, two otherindependent variables doesn’t have significantly impact to DPS, they are CURR andDER.Keyword: Dividend Per Share, Current Ratio, Debt to Equity Ratio, Return OnEquity, and Panel Least Square.

Abstract

AbstractThis research aims to improve the efficiency of the clean water processing by minimizing waste that occured throughout the entire process where in the actual cannot meet with the customer demand in the amount of 3.800.000 m3 per month, while the average process capacity per month only 87% of demand or around 3.306.000 m3 per month. Lean Manufacturing methods that used in this research are Waste Assessment Model and Value Stream Mapping to identify the waste and Value Stream Analysis Tools to choose the most suitable waste analysis tools. According to the result of waste identification in clean water processing at PT XYZ, 2 wastes with the highest ranking found, the wastes are Processing Waste with the precentage of 27,04% and waiting waste with the percentage of 18,96%. VALSAT Tools which used to minimize the waste in this research is Process Activity Mapping (PAM), and according to the analysis of Process Activity Mapping, we knew that 33,84% of the process is Value Added, 3,91% of the process is Non-Value Added, and 62,25% of the process is Necessary Non-Value Added. According to the analysis result mentioned, 2 recommendations were proposed, which are combine a couple of similar inspection process and add more machine to process the PW-55, Coagulan, and Soda Ash. These recommendations will improve the efficiency of clean water processing at PT XYZ where the Value Added increase from 33,84% to 40,28%, percentage of Non-Value Added increase from 4,51% to 4,83% and the percentage of Necessary Non-Value Added decrease from 61,65% to 54,89%. The time needed in the process is also decreasing from 19.950,3 seconds to 16.760,3 seconds. Keyword        : Lean Manufacturing, Waste Assessment Model, Value Stream Analysis Tools, Value Stream Mapping, Process Activity Mapping.
