Abstract

The tools are designed to assist and simplify the machining process, and increase the number of products that can be manufactured with quality maintained. The tools aredesigned to use in the manufacture of the carburetor connection with the Freis. Freisprocess here to cut the work piece that originally shaped like a rectangle into a rhombus.The tool is made by using the principle of supporting and supported by the use ofclamping. Supporting made with a flat surface so that the entire supporting surface is assumed to touch the entire workpiece. Meanwhile, the use of bolt clamping aims to unifyworkpieces with supporting so that the workpiece can not be separated and do not moveduring the machining process takes place. This is evidenced by the equation forcesgenerated by the clamping, the force generated is positive so that the proper tool to use.With this tool, production time becomes shorter and the resulting product is also more precise so that the quality and quantity of product is assured. Production costs necessaryto complete the carburetor connection is also cheaper than without using tools.

Abstract

A product can look like a system, which is something that still has room for consideration of revisions (evaluation). In the evaluation, value engineering is one technique that systematically by using the techniques of identification of the functions required, apply the values and develop alternatives that achieve the best functional balance between cost and performance of a system or product. In compos Mini Machine products, value engineering done to the component cost is quite high (grade A on the ABC classification). Benefit Cost Ratio (BCR) is an important thing that needs to be calculated on the value engineering. The selected alternative for this article is the replacement of roofing material from metal plate to the plastic pulley with cost savings of 55%.

Abstract

Bank BRI Unit Pasar Baru merupakan unit yang baru didirikan beberapa bulan belakangan ini. BRI unit ini melayani berbagai transaksi perbankan, diantaranya menabung, penarikan uang, peminjaman bahkan melakukan transfer baik sesama bank BRI maupun ke beberapa bank yang lain. Bank ini didirikan karena banyak nasabah yang berada di sekitar Pasar Baru yang biasanya melakukan transaksi ke BRI Unit Bandar Buat sekarang sudah dapat dilakukan di BRI Unit Pasar Baru. Ini merupakan salah satu langkah dari BRI untuk meningkatkan kualitas pelayanannya kepada masyarakat. Dalam melakukan kegiatan transaksinya bank ini mempunyai dua teller. Kedua teller ini melayani semua jenis transaksi, sehingga teller harus memahami masing-masing sistem dalam setiap jenis transaksi. Berdasarkan keterangan diatas, Hal ini merupakan masalah yang menarik untuk dibahas karena sistem yang ada pada bank ini masih melakukan penyesuaian dalam operasinya dikarenakan bank ini merupakan unit baru dari Bank BRI. Setiap hari bank ini melayani banyak nasabah untuk melakukan transaksi yang berbeda-beda. Jumlah nasabah yang melakukan transaksi tertentu tidak sama setiap harinya, kadang-kadang pada hari tertentu jumlah nasabah yang menabung tinggi, misalnya pada awal bulan dan begitu juga sebaliknya. Oleh karena itu, keadaan yang dinamis seperti ini perlu dilakukan simulasi sistem agar probabilitas atau kemungkinan dari sistem pada setiap harinya dapat ditentukan. Hasil yang diperoleh dari simulasi yang dilakukan Bank BRI Unit Pasar Baru Padang adalah jumlah teller yang dimiliki sekarang yaitu sebanyak 2 teller cukup untuk melayani nasabah Bank BRI untuk wilayah Pasar Baru dan sekitarnya. Hal ini dikarenakan jumlah nasabah yang datang perhari rata-rata 13-14 nasabah, sehingga utilitas masing-masing teller adalah 0.204 pada teller 1 dan 0.221 pada teller 2.

Abstract

PT. X berencana akan melakukan relokasi gudang ke area yang lebih besar. Pengaturan tataletak produk saat ini menggunakan metoda randomized storage. Produk dengan jenis yang sama ditempatkan pada lebih dari satu lokasi dan tidak adanya lokasi penyimpanan produk yang tetap. Cara penyimpanan seperti ini tidak efisien karena operator pengambilan akan membutuhkan waktu untuk melakukan pencarian terutama jika operator yang bertugas mengambil dan menyimpan produk adalah orang yang berbeda. Disamping itu, cara ini juga dapat mengakibatkan jarak tempuh operator menjadi lebih panjang. Penelitian ini bertujuan merancang ulang tataletak gudang untuk lokasi baru dengan kriteria maksimasi utilisasi luas lantai, memperlancar proses penyimpanan dan pengambilan produk di gudang, dan minimasi total jarak tempuh operator. Perancangan tataletak gudang dilakukan dengan menggunakan metode dedicated storage location policy. Dari penelitian yang dilakukan diperoleh rancangan tataletak gudang usulan memiliki total luas lantai terpakai sebesar 343,80 m2 dengan Ekspektasi total jarak tempuh 4.137 m per hari.
