Abstract

Drinking water depots in Batam City are easy to find because there are in every residential area and an increase in competition is unavoidable. This study aims to determine the factors that influence purchasing decisions at drinking water depots in Batam City. The classical assumption test was carried out to test the regression model in order to obtain a regression model from the least squares method which produces an unbiased linear estimator. The use of multiple linear regression analysis was carried out to determine whether there is a relationship between the influence of product quality, price, location and promotion on purchasing decisions. Product quality variable with tcount 2.845 > ttable 2.06390 with a significant level of 0.009 <0.05 concluded that product quality has a positive and significant effect on the purchasing decision variable, then H1 is accepted. The location variable with tcount 2.663 > ttable 2.06390 with a significant level of 0.013 <0.05 concluded that location has a positive and significant effect on the purchasing decision variable, then H3 is accepted. The author suggests for drinking water depots in Batam City to maintain the quality of gallon refill water products, and choose strategic depot locations to increase profits.

Abstract

Poor material preparation and untidy warehouse PT. XYZ causes difficulties for employees in picking up materials and long distances for picking up materials that have a high picking frequency. The arrangement of the material layout was redesigned to make it easier to pick up material and shorten the distance for picking up material. To improve the layout of the arrangement and tidiness of the warehousing, researchers use the ABC Classification and the application of 5S. The total distance in the initial layout is 2902 meters while the proposed layout is 2278 meters. OMH in the initial layout of Rp. 1,905,000.00 while the proposed layout is Rp. 1,685,706.00. So the total decrease in OMH is Rp. 219,000.00 / month and the distance efficiency obtained is 21.5% / month.

Abstract

ABSTRAK Dalam perencanaan tata letak warehouse perlu mempertimbangkan beberapa hal, seperti berdasarkan jenis barang dan aliran barang. Aliran barang dibedakan menjadi dua, yaitu fast moving dan slow moving. Dampak yang dihasilkan dari tata letak gudang antara lain mengoptimalkan biaya dan kualitas lingkungan kerja menjadi lebih efisien. PT Katindo Utama adalah perusahaan yang bergerak di bidang sector industri dalam penjualan material konstruksi. Kondisi tata letak pada saat ini masih belum berdasarkan suatu perancangan tata letak yang efesien dan efektif sehingga menyebab kan akhir – akhir ini perusahaan sering mengalami kerugian terutama pada area warehouse khusus material keramik, permasalahan yang terjadi ini dikarenakan pada peletakan material keramik yang masih acak dan tidak beraturan sehingga meyebabkan material keramik yang bertumpuk tinggi terjatuh dan pecah. Masalah penting dalam peyusunan material adalah bagaimana mengatur fasilitas-fasilitas agar diperoleh tata letak yang efektif sehingga diperoleh efisiensi yang tinggi dalam pengoperasiannya. Oleh sebab itu masalah tata letak fasilitas perlu diperhatikan karena merupakan suatu permasalahan sistem yang komplek. Metode Class Based Storage adalah sebuah kebijakan penyimpanan gudang yang mengategorikan produk kedalam 3 group kelas yaitu group A, group B dan group C berdasarkan hasil klasifikasi ABC. Teknik penyusunan barang yang digunakan metode class based storage ini adalah menyusun barang group class A di dekat pintu in- out, group class B ditata sesudah kelas A, dan group class C ditempatkan setelah kelas B. Metode ABC merupakan satu metode yang digunakan untuk melakukan pengelompokkan barang ke dalam kelas-kelas tertentu berdasarkan permintaan tahunan dari barang tersebut Hasil perencanaan re-layout membuat penataan barang di warehouse menjadi lebih rapi dan teratur dikarenakan barang yang disimpan dikelompokkan berdasarkan frekuensi pergerakan barang.Sehingga mempermudah melakukan pengambilan dan pengeluaran barang karena barang yang akan di ambil berada pada lokasi yang terdekat dengan I/O

Abstract

UMKM ABDI JASA INDUSTRI merupakan perusahaan yang bergerak di bidang alat berat industri yaitu forklift dan generator set (genset). permasalahan khusus pada UMKM ABDI JAYSA INDUSTRI diantaranya: seringnya terdapat masalah dari jumlah suku cadang, ketidakpastian permintaan persediaan, baik jumlah suku cadang yang dipesan maupun jumlah suku cadang yang disimpan, belum adanya spesifikasi suku cadang dalam penentuan jumlah pemesanan suku cadang forklift, sehingga menyebabkan tempat penyimpanan suku cadang tidak cukup. Penelitian ini bertujuan untuk mengklasifikasikan suku cadang tersebut sehingga mendapatkan jumlah pemesanan yang optimal meliputi ukuran lot per tiap kali pesan, titik reorder point yang jelas, dan adanya safety stock sebagai antisipasi jika terjadi hal yang tidak diinginkan serta perusahaan dapat memperoleh total biaya persediaan yang lebih hemat, yang menjadi permasalahan adalah Persediaan yang tidak terkendali sehingga mengakibatkan tempat penyimpanan suku cadang tidak mencukupi. Tujuan dari penelitian ini adalah untuk mengetahui jumlah persediaan dan pengendalian suku cadang dengan menggunakan metode continuous review system. Berdasarkan dari hasil analisa, pengolahan data, hasil & implementasi dan juga pembahasan, dari data yang di ambil dari penelitian dalam hal membuat pengendalian persediaan suku cadang forklift didapatkan hasil forecasting yang memiliki eror terkecil (MAD) untuk masing-masing suku cadang. MAD pada suku cadang seal plunger adalah 1.25, Battery 0.6, Ban 1.325, King Pin Kit 2.925, Filter Solar 6.25, dan kampas rem 0.925, Dan juga didapatkan hasil forescasting untuk 1 bulan kedepan (agustus) untuk tiap suku cadang adalah: cadang seal plunger 24.4, Battery 3, Ban 7, King Pin Kit 13.3, Filter Solar 24, dan kampas rem 13. Dan didapatkan Hasil penghematan persediaan sebesar Biaya Total Rp25.595.310,00 atau sebesar 6.75%.

Abstract

Competition between companies in the manufacture of increasingly strict industrial products, pt optimech engineering is still facing obstacles such as production time that does not meet the target.This restriction occurs due to the frequent occurrence of products that do not conform to the specifications because the equipment used for production has a low capacity and does not correspond to the quantity of production performed.The purpose of this research is to identify and provide proposals for repair of the work system so that it can eliminate waste found in the cnc department and know the changes that occur in the proposal for repair of the production process.Based on the waste assessment model (WAM), The defect is a percentage of 24.01%, and the waste defect also significantly affects the occurrence of other waste.From the results of the fishbone diagram summarized a number of possibilities which are considered to be the root of the problem, It is a basis for repair recommendations. Work system improvements can be done by accurately predicting and planning production in order to avoid overinventory and could harm the company, supplying employees with more insight into the work and handling of products, and do control for materials before being sent to the next process do the supply of machines according to the production capacity and complexity of products and machine repairs periodically, use or do machine purchases according to the body dimension the labor is owned and does things that can motivate employees to be able to work well.

Abstract

PT Caterpillar Indonesia Batam, a subsidiary of Caterpillar Inc., faces challenges in the painting process of the 6020-excavator chassis, characterized by a high rejection rate and prolonged waiting time between the painting and assembly departments. This study aims to identify the root causes of defects in the painting process and propose solutions to minimize product rejection and improve production flow. The analysis utilizes a fishbone diagram, covering factors related to manpower, methods, machines, and materials. The findings indicate that the primary causes of defects include inexperienced operators, incorrect sanding techniques, damaged spray guns, clogged pump sprayers, and improper material mixing. To address these issues, several improvements are proposed, including regular operator training, refinement of standard operating procedures (SOPs), preventive maintenance for painting equipment, and better raw material preparation. The Value Stream Mapping analysis reveals a lead time reduction of 3,000 seconds, from 72,360 to 69,360 seconds, leading to an increase in process cycle efficiency from 75.8% to 79.1%. These improvements enhance production flow, reduce waste, and optimize the overall painting process.
