The utilization of beds among the elderly, especially those with degenerative diseases, presents health and comfort challenges. To address these issues, this research aims to redesign elderly beds using a participatory ergonomics method at Madania Potonoro Nursing Home. By involving the elderly and caregivers in the process, the research findings highlight the need for bed improvements. The proposed design includes additional features such as a folding table, bookshelf, cane holder, assistive standing devices, and a drink holder, based on identified needs. Anthropometric dimensions, including Shoulder Width (SW), Height (H), Popliteal Height (PH), Elbow Height in Sitting (EHS), Elbow Height in Standing (EHS), Seat Depth (SD), and Maximum Grip Diameter (MGD), serve as guidelines for bed design. Analyzing these dimensions at the 5th, 50th, and 95th percentiles, adjustments are made to accommodate additional attributes or features on the bed. The recommended design not only provides optimal comfort and safety for the elderly but also improves their overall quality of life. This research emphasizes the importance of involving users in the design process to ensure solutions align with their needs and preferences.

Inventory of raw materials is one of the crucial problems in the company. Errors in determining the size of raw material inventory is very influential for the smooth production of the company. PT Semen Bosowa Maros is a private company that focuses on cement production. This study aims to avoid excess and shortage of raw materials by calculating the amount of raw material inventory at PT Semen Bosowa Maros. This study uses the Min-Max Stock method. The research data was obtained from the company's annual data with related parties. The results of the study obtained safety stock values of Silica Sand 166.46 ton’s, Gypsum 1482.96 ton’s, Fly Ash 33.71 ton’s, and Trass 30.76 ton’s. Then, the minimum inventory calculation is carried out, it is known that the minimum inventory results are found in Trass raw materials of 260.18 ton’s while the results for maximum inventory are in Gypsum of 22117.18 ton’s. After calculating the min-max, an order policy can be obtained for each material, Silica Sand 1074.85 ton’s, Gypsum 9575.63 ton’s, Fly Ash 217.68 ton’s, and Trass 198.65 ton’s.

PT. IKI is a shipbuilding company owned by the Indonesian government engaged in production. Preliminary observations found that there was an imbalance in the workload received by each employee, causing employees to work beyond operating hours, sometimes also working outside the company's working days. Workload analysis is very important to calculate exactly how many employees are needed to complete all tasks in a part or department in the company. In this research was conducted to identify the workload received by employees of the plumbing department, and determine the number of employee needs based on their workload. This study uses the full time equivalent method to identify the workload received by employees and determine the number of employee needs based on their workload. The results of this study indicate that there is an uneven workload at one work station, where from the results of calculations using the FTE method it is known that the workload of employees 1 and 2 is classified as overload and employees 3, 4, 5, 6, 7, 8, 9, and 10 in the normal category. Based on the results of this study, the number of employees was increased, namely 2 people. So the optimal number of employees is 12 people. Another suggestion is for employees who experience an overloaded workload or an uneven workload at one work station, then some of the job descriptions for employees who have an overloaded workload are given to employees who have a normal workload.

Penelitian ini memiliki tujuan dalam mengevaluasi perencanaan kapasitas produksi minyak kelapa sawit di PT. Merbaujaya Indahraya selama periode dua belas bulan menggunakan metode RCCP (Rough Cut Capacity Planning) dan MPS (Master Production Schedule). Fokus penelitian adalah pada identifikasi ketidakseimbangan antara kapasitas kerja perusahaan dan fluktuasi permintaan dari konsumen, serta eksplorasi strategi peningkatan kapasitas produksi guna mengakomodasi variasi permintaan pasar. Temuan dari penelitian menunjukkan bahwa kapasitas produksi perusahaan belum sesuai untuk memenuhi kebutuhan dari konsumen dengan permintaan yang beragam. Meskipun telah dilakukan penambahan jam kerja lembur dan strategi lainnya, kapasitas produksi hanya mencukupi pada beberapa bulan tertentu. Rekomendasi untuk menambah mesin produksi atau menggunakan subkontrak dengan perusahaan sejenis sebagai langkah-langkah untuk menjaga eksistensi perusahaan. Penelitian selanjutnya direkomendasikan untuk menggunakan metode RCCP dengan pendekatan CPOF guna mendalami analisis kapasitas produksi di PT. Merbaujaya Indahraya dan meningkatkan responsivitas perusahaan terhadap fluktuasi pasar.

Efficiency in logistics distribution is an important aspect in improving the competitiveness of the company. UD. Gudang Telur is a company engaged in the distribution of chicken eggs located in Makassar City, facing obstacles in the form of irregular distribution routes and non-optimal utilization of transport capacity. Current distribution is carried out without paying attention to the distance factor and the location of the destination in a structured manner, so that the average transportation cost reaches Rp. 8,000,000. per month. Therefore, it is necessary to evaluate the distribution path of chicken eggs so that an optimal distribution route is obtained using the Saving Matrix method, this method allows combining several consumers in one route to minimize mileage and transportation costs. Case studies were conducted on six retailers with various travel distances and transportation capacity requirements. Based on the analysis results, the savings achieved reached 48.28% for mileage, from 163 km to 84.3 km, and 58.62% for transportation costs, from Rp 1,982,855 to Rp 820,428. These results show that the Saving Matrix method is effective in designing optimal distribution routes by considering transport capacity and distance traveled, as well as reducing significant operational costs.

Workload is something that arises due to excessive activity demands. The workload is not proportional to the number of available workers because of the high target of pipe production while the number of workers is lacking so that human resources cannot work productively, especially in the production department at PT. Harapan Jaya Multi Bisnis. The purpose of this study is to determine the workload of employees in pipe production and determine the optimal number of workers. This study uses the Work Load Analysis (WLA) method to analyze the workload in determining the optimal number of workers. The results of this study after calculating the workload, it is proposed that the fixed cutting section is 2 people with a workload of 62.65%. In Branding, in real terms there is 1 person with a total workload of 11.73% and an average workload of 11.73%. After calculating the workload, it is proposed that the shooting section still be 1 person with a workload of 11.73%, because if additional workers are added, the workload will be too low. The time needed to complete the activity is 7 hours per day. After calculating the workload, Quality Control is proposed to be 1 person, because if additional workers are added, the workload will be too low, namely 7 hours per day.
