Analisis Pemborosan Menggunakan “9 Waste" Pada Proses Produksi Pt Abc

Sistem produksi yang efektif dan efisien akan menghasilkan produk yang berkualitas, sehingga perusahaan tidak mengalami kerugian. Kerugian yang dialami suatu perusahaan salah satunya karena permasalahan pemborosan (waste). Pada penelitian ini bertujuan untuk menganalisis waste pada produksi produk X di PT ABC menggunakan pendekatan Lean. Hasil klasifikasi menunjukkan bahwa keseluruhan aktivitas produksi dari setiap proses yang didapat adalah sebesar 22% untuk value-added activity (VA), 22% untuk non value-added activity (NVA), dan 56% untuk necessary non value-added activity (NNVA). Dari hasil klasifikasi tersebut kemudian dapat diidentifikasi dalam 9 faktor yang dapat menyebabkan waste. 9 Waste tersebut disingkat dengan E-Downtime, yang terdiri dari Environmental, Health, and Safety (EHS), Defect, Over Production, Waiting, Non-Utilizing Employee, Transportation, Inventory, Motion, dan Excess Proceessing. Berdasarkan hasil identifikasi dan analisa, permasalahan waste yang terjadi adalah setiap proses operasi selesai, benda trial untuk produk X akan dilakukan pengukuran oleh tim QA, dan pengukuran tersebut dilakukan terus berulang hingga operasi terakhir. Selain itu, terdapat antrian dari tim QA sehingga menimbulkan downtime yang cukup lama, akibatnya lead time produksi akan lebih lama. Usulan perbaikan yang direkomendasikan oleh peneliti adalah supaya pengukuran benda trial oleh tim QA dilakukan secara sekaligus yaitu satu kali setelah proses produksi dari operasi pertama sampai operasi terakhir telah selesai. Hal tersebut dapat meminimalkan waktu menganggur operator produksi sehingga mampu menghilangkan waste di PT ABC.

Co-Opting Regulation: Professional Control Through Discretionary Mobilization of Legal Prescriptions and Expert Knowledge

The governance of front-line professionals is a persistent organizational problem. Regulations designed to make professional work more legible and responsive to both organizational and public expectations depend on these professionals’ willing implementation. This paper examines the important question of how professional control shapes regulatory compliance. Drawing on a seventeen-month ethnographic study of a bioscience laboratory, we show how professionals deploy their discretionary judgment to assemble environmental, health, and safety regulations with their own expert practices, explaining frequently observed differential rates of regulatory compliance. We find that professional scientists selectively implement and blend formal regulations with expert practice to respond to risks the law acknowledges (to workers’ bodies and the environment) and to risks the law does not acknowledge but professionals recognize as critical (to work tasks and collegiality). Some regulations are followed absolutely, others are adapted on a case-by-case basis; in other instances, new practices are produced to control threats not addressed by regulations. Such selective compliance, adaptation and invention enact professional expertise: interpretations of hazard and risk. The discretionary enactment of regulations, at a distance from formal agents, becomes part of the technical, practical, and tacit assemblage of situated practices. Thus, paradoxically, professional expert control is maintained and sometimes enhanced as professionals blend externally imposed regulations with expert practices. In essence, regulation is co-opted in the service of professional control. This research contributes to studies of professional expertise, the legal governance of professionals in organizations, regulatory compliance, and safety cultures.

Use of zebrafish (Danio rerio) as a model for research in toxicological studies

Danio rerio, commonly known as zebrafish, is a freshwater aquarium fish and is native to parts of South Asia. It is considered an important organism for analyzing the noxious effects of toxicants and pollutants of the environment. In terms of the molecular signaling pathway, molecular properties, organ functions and structures, and neurogenesis, zebrafish are similar to certain other higher-order vertebrates. The 3Rs, refinement,reduction, and replacement in researchhavegradually evolved with time. The accumulation of toxicants in the environment and the human health conditions from exposure to toxicants present in the environment is a serious concern, and zebrafish serves as an excellent model to research such effects. The three Rs are met by zebrafish, larvae can also be used to discover harmful medication compounds, permitting safer compounds to be explored in model organisms and it could also be used to substitute certain toxicological testing.Also, because embryos are fertilized outside and are visible during the initial days of life, the early larval model of zebrafish enables flexibility to animal research study, subsequently reducing the number of animals employed in experiments.For various experimentation studies, the larva of the zebrafish is proved to be a useful model for the system.Thus, being a good test system, zebrafish are used in environmental health and safety studies.This review focuses on the toxicological studiesin zebrafish and outlines the toxicological studies done on zebrafish with arsenic and 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) as well as microplastic toxicity.

A definition and categorization system for advanced materials : the foundation for risk-informed environmental health and safety testing

Novel materials with unique or enhanced properties relative to conventional materials are being developed at an increasing rate. These materials are often referred to as advanced materials (AdMs) and they enable technological innovations that can benefit society. Despite their benefits, however, the unique characteristics of many AdMs, including many nanomaterials, are poorly understood and may pose environmental safety and occupational health (ESOH) risks that are not readily determined by traditional risk assessment methods. To assess these risks while keeping up with the pace of development, technology developers and risk assessors frequently employ risk-screening methods that depend on a clear definition for the materials that are to be assessed (e.g., engineered nanomaterial) as well as a method for binning materials into categories for ESOH risk prioritization. In this study, we aim to establish a practitioner-driven definition for AdMs and a practitioner-validated framework for categorizing AdMs into conceptual groupings based on material characteristics. The definition and categorization framework established here serve as a first step in determining if and when there is a need for specific ESOH and regulatory screening for an AdM as well as the type and extent of risk-related information that should be collected or generated for AdMs and AdM-enabled technologies.

A Preliminary Assessment of the ‘Greenness’ of Halide-Free Ionic Liquids—An MCDA Based Approach

With the growing interests in non-aqueous media for diversified applications, ionic liquids (ILs) are frequently considered as green solvents. While the environmental, health, and safety assessments of the commercially developed ILs and their ‘greenness’ status are in debate, research focus is shifting towards the application of halide-free ILs for diversified applications. To clarify the situation on their greenness, and to understand if they really possess safe characteristics, we performed an initial assessment of 193 halide free ionic liquids composed of four groups of cations (imidazolium, pyridinium, pyrrodilinium, piperidinum) and 5 groups of anions (acetate, propionate, butyrate, alkanesulfonates, alkylsulfates). The ‘Technique for Order of Preference by Similarity to Ideal Solutions’ (TOPSIS), a multi-criteria decision analysis (MCDA) tool that allows ranking many alternatives is applied by carrying out the assessment against 14 criteria that includes hazard statements, precautionary statements, biodegradability, and toxicity towards different organisms. The ranking results obtained against the set of criteria considered show that the halide free ILs placed between recommended polar solvents: methanol and ethanol can be considered to be safer alternatives in terms of ‘greenness’. The study in this work provides an initial assessment of the halide-free ionic liquids evaluated against 14 criteria in terms of their safety characteristics (“green character”) using the MCDA-TOPSIS approach.

Assessing Responsible Care implementation for sustainability in Malaysian chemical industries

PurposeThe Responsible Care programme was first introduced in Canada in 1985 and now is implemented worldwide as one of the chemical industries' commitments to improve the industries' public image as well as their performance in health, safety and environmental aspects. In Malaysia, the Responsible Care programme has been implemented since 1994 with a current total of 148 companies pledged to implement it in their company; however, the effectiveness of the programme remains unknown. Hence, this paper aims to assess the effectiveness of the Responsible Care programme in improving performance in the environment, health and safety in terms of documentation, training, selection processes and stakeholders' engagement for the sustainability of chemical industries.Design/methodology/approachA survey was administered to the Responsible Care signatory companies in Malaysia. Of these, a total of 132 member companies either produced or provided services related to chemical products.FindingsThe majority of signatory companies agreed that the Responsible Care programme did improve their performance in the environment, health and safety. Besides that, the signatory companies were also keeping up their commitment to ensuring documentation, training, selection process and stakeholders' engagement run smoothly in line with Responsible Care's mission.Originality/valueAfter more than two decades of implementation in Malaysia, it is important to assess the Responsible Care programme's effectiveness. As an increasing number of chemical firms, without good management, it will possibly pose a danger to the environment and human health and safety. Through assessment, advances in Responsible Care management practices will considerably increase programme effectiveness in terms of environmental health and safety.

Using a Quality-Driven Approach to Maintain an N-95 Respirator Supply During a Pandemic-Driven Global Shortage

Background: Reports of hospitals overwhelmed by COVID-19 patients created severe shortages of personal protective equipment (PPE). In this large academic medical system, we used a systematic team approach to proactively maintain an adequate PPE supply. The team consisted of staff from multiple departments including infection prevention, environmental health and safety, operational efficiency, and supply chain. The healthcare system solicited donations of PPE, and our team was tasked with developing a sustainable method to provide healthcare workers with safe and effective N-95 respirators. Respirators are normally fitted to our 6,000+ healthcare workers through a fit-testing process using 4 models of N-95s. We received >60 models, many in small quantities, posing a new level of complexity that prevented use of our typical fit-testing method. Methods: Donated respirators were manually verified on the CDC/NIOSH website to validate approval or approved alternative. A categorization system was developed, and respirators were sorted based on quality, style, and condition. User seal checks replaced qualitative fit testing due to the uncertain and quickly changing respirator supply. Staff were educated about the importance of performing a seal check to evaluate respirator fit and were provided instructions for what to do if they failed a seal check. We performed limited quantitative fit testing on a small group previously fit tested to 1 of the 4 models of N-95s normally stocked to identify the most effective alternative respirators to serve as substitute N-95s. Results: We were able to provide staff with new N-95s and delay the release of reprocessed N-95s. Overall, 18 models of respirators were tested on staff for filtration effectiveness and fit. We deemed 61% masks to be of last resort, and these were not released. We determined that 39% were acceptable as an alternative for at least 1 of our usual respirator models. However, only 3 models (17%) available in small quantities fit wearers whose size was in shortest supply. This scarcity led to the evaluation and purchase of a new respirator prototype for small N-95 wearers, which was an important success of our team’s work and for staff safety. Conclusions: Collaboration between teams from a variety of backgrounds, using both qualitative and quantitative data, resulted in a sustainable method for receiving, sorting, and evaluating donated N-95 respirators, ensuring the delivery of a steady supply of effective N-95 respirators to our staff. This quality-driven approach was an efficient and effective strategy to maintain our N-95 respirator supply during a pandemic driven global shortage.Funding: NoDisclosures: None
