The appearance of attractive packaging in a product is something that is a major factor apart from product quality. UMKM Keripik Singkong Usaho still have problems with product packaging which is still simple using ordinary plastic without any labeling. So that research and packaging design are needed using the Quality Function Deployment (QFD) method. The results of the study obtained 18 items that become consumer criteria for the packaging of chips products. The results of the House of Quality show that the greatest desire value of consumers (0.07) for the design of chip packaging is an attractive packaging shape (A1), displaying the expiration date (A7), listing the composition (A10), including the halal logo (A11), packaging materials resistant to oil and water (A12), and the position of the product logo is easy to read (A17). So that the technical criteria are variations in packaging color, variations in writing color, variants of packaging materials, and variants of packaging shapes. The proposed packaging design for the chips has two models, red packaging color for the spicy flavor and green packaging color for the original flavor, where each package includes the expiration date, product composition, and halal logo.

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.

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.

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

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.

Despite the significance of mask use, there is still a lack of understanding among Indonesians, with youngsters adhering to the wearing of masks at a rate of 51.6%. The causes include heat, irritability, pain, difficulty breathing, social rejection, and improper mask size and form. One of the ergonomics-related issues is the shape and size of the mask, so one solution is to use anthropometric data while designing the mask. In this study, groups of kids between the ages of 6 and 11 were recruited to redesign masks based on their anthropometric measurements. According to the findings, the distances between the nose's tip and the lower jaw joint (T), the tip of the nose and the rear of the ear bone (U), the nose's distance from the chin (C), and the distance between the eyes and the chin were utilized as anthropometric measurements in the construction of the mask. (B). The mask's size is determined. The mask's length without the strap is 11.16 cm, its length with the strap is 14.53 cm, the central mask's width is 7.02 cm, and the mask's total width is 13.70 cm. The size of the mask from the study and the size of the mask currently on the market differ after measurements were taken into account for anthropometric data

Service is the main indicator of the sustainability of a service. The quality of services is the main factor that must be considered in maintaining the existence and competition of services, including health facility services. This research was conducted at one of the health service providers in the city of Batam. One aspect of health service quality is queuing service. Therefore, the quality of service in the queuing system in health facilities is an interesting thing to research. This research measures the level of optimality of the queuing system currently in effect at the Saffira Mitra Medika clinic. The measurement focuses on service time, the number of patients served, and the waiting time for patients to be served in the queue system. The results of measuring the current queuing system are compared with other proposed queuing system scenarios, so that the level of patient satisfaction as customers is met. The proposed queuing system was obtained through a simulation approach, with the help of Flexsim software. A simulation approach was chosen to facilitate modeling in the proposed queuing system
