Abstract

Placement and determination of waste landfill locations in each city is very important. The location of a landfill that is not well organized will cause some negative consequences, which can cause damage to infrastructure; local environmental pollution; release of methane gas which is called organic decomposition; means of carrying diseases such as rats and flies; and simple interference. The existing landfill in Gresik city, precisely in the Ngipik Village, needs to be evaluated again because besides being in an urban location, the TPA has already been overloaded. Stakeholders need to find alternative locations to organize the city and make the city more comfortable for residential and urban areas. The solution to the problem requires a support method to find a solution. One method of supporting the decision is the method of transportation, this method can help to determine the optimal location of various alternatives. The transportation method discusses the distribution of goods from a number of sources (supply) to various destinations (requests) with the aim of minimizing the costs of transportation that occur. The results of calculating the optimal solution for each location using POM software by using a combination of existing landfill with TPA proposed I total costs spent in a day Rp.1.764.105,20. Temporary costs incurred using the existing landfill combination with TPA proposed II is Rp. 1.981.150,60. And the costs incurred using the existing landfill combination with the TPA proposed I and TPA proposed II ​​amounting to Rp.2.121.919,80. The combination of the use of the existing landfill with TPA proposed I has the lowest cost value of all alternatives.

Abstract

In this study, one-dimensional cutting pattern is discussed. This includes fulfilling demands for some items with different lengths by cutting some stocks of standard length available. In this problem, the patterns – the way the standard length is cut – is obtained in such an optimal ways that the trim loss becomes as minimum as possible. The decision variables are the amount of the standard lengths cut according to certain patterns. Then the problem is formulated into a linear programming model. Due to very large number of the variables and restriction to integers, the problem is the type of large scale linear integer programming. For simplicity, restriction to integer is dropped. Then the very large number of the variables is handled by considering only the favorable cutting patterns; list of all possibleways in which a standard stock may be cut is not needed. The favorable cutting pattern is then generated by using column generation technique by solving auxiliary problem in the form of a knapsack problem. The integer optimal solution is obtained by rounding it upward

Oleh sebab itu, dalam pemasangan rudder blade atau kemudi kapal harus benar – benar presisi dan center terhadap dimensi kapal. Dalam pemasangan rudder blade selama ini memerlukan banyak waktu, man power, peralatan dan proses yang sangat lama. Untuk meminimalis waktu serta man power dalam mempercepat pemasangan rudder blade maka dibutuhkan improvement dari metode pemasangan rudder blade yang selama ini digunakan( Metode Existing/Manual) ke pemasangan rudder blade yang dapat mempercepat proses pemasanganya dalam hal ini yang disebut dengan Metode Jig Hydraulic. Selain itu dengan diciptakan alat bantu untuk pemasangan rudder blade maka diharapkan juga mendapat hasil yg lebih akurat. Hasil dari analisis serta pengolahan data dan perhitungan, di dapat efisiensi JO rata-rata 60 JO dan efisiensi sekitar 58,82%. Jika dilihat dari segi biaya untuk pemasangan rudder blade dengan metode jig hydraulic dapat mereduce biaya hingga Rp 40.800.000,00 (Empat puluh juta delapan ratus ribu rupiah) dibandingkan dengan metode existing/manual yang saat ini dilakukan. Dari hasil perhitungan tersebut dapat dipastikan metode pemasangan rudder blade menggunakan jig hydraulic lebih effisien untuk waktu, biaya serta JO dibanding dengan metode existing/manual. Oleh sebab itu proses pemasangan rudder blade menggunakan metode jig hydraulic layak dipertimbangkan untuk digunakan dalam percepatan proses pemasangan rudder blade
