Abstract

PT. Mustikarama Citraperdana is a manufacturing industry that produces  safety box. This company has been developing which is known from the increase of demand, production volume, and also the types of product. Problem faced by PT. Mustikarama Citraperdana is sending customer order does not match the shipment date by a percentage of 52.44%. Initial observations, inaccuracy of time in order delivery caused by the production planning problem that is not appropriate.This thesis will design improvements to overcome the problem of production planning that caused the company experienced difficulties in the form of an order sending customer order does not match the shipment date. The design improvements are given in the form of production planning and inventory control of raw materials.

Abstract

PT X is a manufacture company that provides medical facilities for its permanent employee in form of medical benefits. The medical benefits claim proposed by the employees will be processed in PT X’s medical benefits system. The company requires that at least 98% of the claims are processed on the same day as the day those claims are proposed. That requirement can only be fulfilled with overtime work. The average of overtime work per month per admin is 14 hours. The improvement of the efficiency can be done by doing enhancement of the approval and revise processes of the previous medical benefits system. The enhancement is done by creating unique key and barcode for each medical claim, so that each of the new claim form is going to have unique key and barcode. HR admin would be able to do scan barcode process that would accelerate PT X’s medical benefits system. The result of the implementation of this enhancement is the acceleration of medical benefits system of PT X. The implementation results in the decrease of the process time as much as 31% of the prior condition and the investment fund will have returned in less than three months.

Abstract

This study was conducted to give the proposed model of humanitarian logistics coordination for the handling of natural disasters in Indonesia by involving the private sector. The private sector, involved in disaster management, is DHL. The analysis techniques used are the competitive profile matrix to evaluate the performance of each agency involved and RASIC analysis to determine the role of each institution in each activity. The results showed that the private sector is still less involved in Indonesia’s disaster management and the role of some institutions in some activity is still not quite right. DHL is proposed to be involved because it has sufficient capacity to be involved in disaster management. Activities that can be roled by DHL are involving in the delivery and distribution of relief and to help receive relief from foreign parties. Activities that need to be changed is the provision of funds, the making standardization relief, and assessment.

Abstract

Laris Elektronik is a distributor of electronic house appliances whose sales targets are smaller stores. The current warehouse system which laris currently use is mainly done manually by human resources and is centered on the owner. A good system must never rely on a single individual and should be done in a regular order. The main purpose of this thesis is to create a better warehouse system which is more automatic  and less dependant on the owner. There are 3 main improvements in this thesis, i.e. inventory control system, construction of a database for stocking purpose, and warehouse layout improvement.Inventory control system is done by changing the method of goods ordering into periodic review with 3 days duration. The duration is prolonged from the current 1 day review system because there are too many stock inspections done with the old system. The construction of database is done to hasten the input of stock datas and to give employees access toward a certain information regarding goods (e.g. Number of goods left, price of goods) that was originally known only by the owner. The layout improvement is done based on the preceding inventory control improvement. The current random goods layout is given order based on the speed of sales and optimal stock value which is decided in the inventory control system.

Abstract

Competition in the industry is getting tighter forcing every company to have a strate-gy to minimize operational costs. Strategies that can be done to shipping cost reduction. Delivery is very influential in the company's operating costs, and one method that can help the enterpris-es to determine which method of service Vehicle Routing Problem (VRP). VRP has several ways of settlement to this problem, one of which is the Savings Method or the method of Clarke and Wright. Scheduling of vehicles to make deliveries also the key to be able to set the number of ve-hicles that will be used so it does not do waste. Research in this final project will determine the route and vehicle scheduling for the better through these factors, the volume of goods, arrange-ment of goods, and vehicle scheduling. The results of this study provide improvements to the company with an average percentage of 19.68% for vehicle fuel cost savings.

Abstract

PT.Y is a company that produce cigarette. Currently PT.Y wants to revise the spare part receiving system that was applied. Spare part receiving process first start at main store, then will be delivered to sub store. The improvement that wants to be applied is to eliminate the main store, so that spare part can be delivered directly to warehouse sub store. By portraying the current process using value stream mapping, two waste could be eliminated if warehouse main store role is erased. Unnecessary transportation and over processing is the occurring waste in these process. The proposed counter measure is to change all store location for all material in the data base so that when PR was created the store location will automatically determine the real receiving warehouse. The proposed counter measure can shorten the processing time by 16.918,91 second per day. Counter measure can also decrease transportation fees by Rp.6.140,00 per day.

Abstract

UD. Wirakarya merupakan perusahaan dagang yang bergerak dibidang penjualan besi, barang yang dijual meliputi besi konstruksi, pipa besi, dan plat besi. Seiring perkembangan jaman dan berkembangnya pasar di sektor konstruksi yang tidak diimbangi dengan adanya tempat dan sistem yang memadai untuk penyimpanan barang. Keadaan tersebut menyebabkan kerugian bagi perusahaan. Berdasarkan hal tersebut, perusahaan akan membuat gudang baru untuk tempat penyimpanan dan perbaikan sistem manajemen pergudangan.Metode yang digunakan adalah dengan klasifikasi ABC, periodic review, safety stock, maximum   inventory, dan tata letak.Hasil yang diperoleh pada skripsi ini adalah jumlah kapasitas penyimpanan yang meningkat, penurunan biaya persediaan sebesar 9%, tata letak untuk gudang baru, sistem penerimaan dan pengeluaran barang di gudang baru.

Abstract

Kemajuan teknologi informasi yang semakin canggih di era globalisasi saat ini, diperlukan sebuah sistem yang mendukung sistem penjadwalan trucking dan proses pengiriman barang sehingga dapat mempermudah pekerjaan para staf penjadwalan. Pada makalah ini dibuatkan sebuah website sistem penjadwalan trucking dan heavy equipment untuk perusahaan yang dapat memberikan informasi penting untuk konsumen dengan sistem pencarian data barang yang mudah diakses dan dilengkapi informasi lengkap mengenai perusahaan beserta proses pengiriman barang. Dalam sistem penjadwalan yang dibuat, terdapat satu fitur tambahan yang berguna untuk menyamaratakan beban kendaraan, sehingga kondisi setiap kendaraan dapat terkontrol. Fitur ini menggunakan Analytical Hierarchy Process (AHP) untuk menghitung besar bobot kriteria pemilihan, serta digunakan scoring untuk mengetahui kendaraan mana yang akan digunakan untuk proses pengiriman tertentu. Sistem penjadwalan trucking dan heavy equiment berbasis web ini dirancang menggunakan teknologi PHP versi 5.1.2, Macromedia Dreamweaver 8, dan MySQL versi 5.0.11-beta Dari hasil implementasi dan pengujian sistem serta kuesioner dapat disimpulkan bahwa fitur-fitur yang telah disediakan pada website sistem penjadwalan, mampu menjawab permasalahan yang dihadapi oleh perusahaan dimana sistem dapat melakukan penjadwalan trucking dan alat berat dengan memperhatikan faktor kemudahan dan memberi informasi detail dari setiap data yang akan dicari, selain itu juga memberikan hasil AHP yang signifikan, sehingga dapat menunjang kinerja perusahaan agar lebih efisien dan meningkatkan kepercayaan serta memberikan kepuasan tersendiri bagi para pelanggan.
