Abstract

Less ergonomic work postures such as bending and squatting have the potential to pose work risks. When muscles receive static loads repeatedly and for a long time, it causes complaints of damage to joints, ligaments, and tendons commonly referred to as musculoskeletal disorders (MSDs) or injuries to the musculoskeletal system. This study aimed to determine the level of risk of work postures performed by workers in each work activity using the Rapid Entire Body Assessment (REBA) and Ovako Working Posture Analysis System (OWAS) methods and provide suggestions for improving work postures to minimise the occurrence of work risks. The research was conducted at the foundry of metal in the Casting section. Initial data in the form of Nordic Body Map (NBM) questionnaire data used to determine complaints in the musculoskeletal system and data in the form of image documentation on each work activity used as material for analysing the assessment of the REBA and OWAS methods. Proposals for improving the working posture were given in the form of adding foundations for moulding and pattern-making activities, the design of tools for metal liquid pouring activities, and furnace designs for metal smelting. Proposals for improving the working posture were given in the form of adding foundations for moulding and pattern making, the design of tools for metal liquid pouring, and furnace designs for metal smelting.

Abstract

A good raw material and consumables control planning system is important in the production process so that the process runs according to schedule and target. Brake system company is a manufacturing company engaged in brake systems. Concerning the control of consumable material, this company often experiences overstock in warehouses, causing an overrun in inventory costs and investment cannot develop. One of these conditions can be influenced by the ordering method applied by the company which is still not appropriate. The purpose of this study is to find out and provide proposed to companies related to the cost of consumable inventory by comparing the three methods of determining lots based on Fixed Order Quantity (FOQ), Economic Order Quantity (EOQ), and Fixed Order Quantity Proposed (FOQ Proposed) is the FOQ method combined with the Lot for Lot (LFL) principle to determine the method with the most optimal inventory cost. From the results of the study, it is known that the Proposed FOQ method has the lowest total inventory cost compared to the other two methods. The proposed FOQ approach could reduce inventory costs by up to one-third times the previous cost.

Abstract

Sukorintex merupakan sebuah perusahaan yang bergerak di bidang tekstil dengan produk utamanya adalah kain sarung berlabel Wadimor. Permasalahan yang dihadapi oleh PT. Sukorintex yaitu kecacatan yang terjadi akibat proses tenun oleh mesin Weaving 1 sehingga tidak dapat memenuhi standar kualitas sarung yang telah ditetapkan oleh perusahaan. Jumlah produk yang diproduksi mesin weaving 1 memiliki jumlah paling tinggi dibandingkan dengan mesin lain. Jika dibiarkan dan terjadi terus-menerus hal tersebut akan merugikan perusahaan secara finansial maupun non finansial. Tujuan dari penelitian ini adalah mengupayakan pengendalian kualitas agar hasil produksi kain sarung memiliki kualitas yang sesuai dengan standar perusahaan. Penelitian ini menggunakan metode SPC (Statistical Process Control) untuk monitoring, mengendalikan, menganalisa, mengelola serta memperbaiki produk dan proses produksi dengan metode statistik. Kecacatan yang terjadi akibat proses di mesin weaving 1 adalah sebanyak 7,8% dari total produksi sedangkan standar toleransi kecacatan dari perusahaan sebesar 5,8%. Salah satu faktor yang memengaruhi banyaknya kecacatan kain sarung adalah faktor metode, yakni benang lusi dobel dengan tingkat kecacatan tertinggi yang disebabkan oleh kesalahan pada saat proses pencucukan.

Abstract

Toilet merupakan area vital dalam setiap lingkungan, baik itu rumah, tempat umum, atau fasilitas komersial. Kebersihan toilet merupakan aspek yang sangat penting bagi kesehatan dan kenyamanan pengguna. Apalagi jika pengguna toilet tidak sadar akan kebersihan, mengakibatkan toilet bau dan ruangan toilet menjadi pengap. Namun, pemantauan kebersihan toilet secara manual sering kali tidak efisien dan tidak memberikan informasi secara real-time tentang kondisi aktual. Sehingga dibutuhkan suatu sistem otomatis dan real-time yang dapat memantau kebersihan toliet, terutama di lingkungan rumah tinggal. Implementasi teknologi Internet of Things (IoT) dapat menjadi solusi yang efektif untuk memantau dan mengelola kebersihan toilet secara efisien. Tujuan dari penelitian ini adalah untuk merancang dan mengimplementasikan sistem "Smart Toilet" berbasis Internet of Things (IoT) yang mampu memantau kebersihan toilet secara real-time. Sistem ini diharapkan dapat memberikan informasi yang akurat dan cepat tentang kondisi kebersihan toilet, sehingga memungkinkan tindakan yang cepat dan tepat dalam pemeliharaan dan sanitasi. Metode riset pada peneltian ini menggunakan Arduino dengan sensor suhu dan kandungan gas sekresi dari manusia. Standar amonia untuk bau biasa adalah sekitar 2 ppm, sedangkan suhu ruang toilet yang nyaman berkisar antara 22-25 derajat celcius sedangkan kelembapan berkisar antara 30 – 60 persen. Sistem smart toilet ini bekerja dengan mendeteksi suhu dan bau toilet yang diatas standar yang ditetapkan secara real-time, untuk dapat dilakukan penyemprotan lantai dengan air pembersih secara otomatis dan menyalakan alat sirkulasi udara melalui smartphone. Sistem ini diharapkan dapat membantu meningkatkan kesehatan masyarakat melalui pengelolaan kebersihan yang lebih efektif dan real-time.
