Reducing Dandory Exchange Process Time on 1800 Ton Injection Molding Machine Using the Single Minute Exchange of Dies (Smed) Method at PT Takagi Sari Multi Utama

Takagi Sari Multi Utama is an automotive company engaged in injection molding, producing automotive products such as motor vehicle parts, car interiors, and exteriors. One of the main influences of the prolonged dandory process is the distance between the mold parking area and the machine, resulting in a total process time of 48.95 minutes, while the company's standard is set at 40 minutes. Minimizing the time can cause the dandory process of mold change using the Single Minute Exchange of Dies (SMED) method by converting the time of internal setup activities into external setup activities. The improvement results using the Single Minute Exchange of Dies (SMED) method reduced the time to 27.67 minutes or equivalent to 1,660.13 seconds. The reduction in dandory mold change process time on the 1800T injection molding machine is 21.29 minutes or equivalent to 1,277.16 seconds, with a percentage decrease of 44%

Implementasi Metode Single Minute Exchange of Dies di Bagian Packing Dalam Upaya Meminimasi Pemborosan (Waste) Dan Peningkatan Produktivitas (Studi Kasus PT. SF)

PT. SF is a company engaged in the pharmaceutical industry. This company has several problems faced, one of the problems that often occurs is the high time in the machine setup process , so that the fulfillment of production targets is disrupted. The number of types of products makes the number of model change processes which of course have different types, so that this has an impact on the amount of production produced. Therefore, this study was conducted to minimize setup time using the single minute exchange of dies (SMED) method. The results showed that there were 5 work stations in the packing section, where of these 5 work stations the one with the highest setup time was the cartoning machine workstation with an initial setup time of 63,84 minutes. After applying the single minute exchange of dies (SMED) method, the setup process can be lowered to 46,69 minutes. So it can save set-up time by 17.15 minutes.

Reducing dandori processing time using the single minute exchange of die method in swaging areas in automotive rubber components company

The automotive component company is engaged in the manufacture of automotive rubber components. Based on data obtained from field observations, it was found that the Dandori process on the swaging Nox machine, especially TA090 type, had the highest downtime compared to another component. Based on these problems, research uses the Single Minute Exchange of Die (SMED) method to reduce Dandori downtime in the TA090 swaging process. The SMED method was carried out in three stages: 1. identify internal and external setup, 2. Converting internal to external setup, and 3. Streamlining aspects of operation. In addition, it also used data processing tools, namely SMART, fishbone, and 5W+1H as support to solve this problem. Improvements were made by converting internal work elements into external ones and streamlining aspects of operation by improving on man, method, and machine/tools categories. The result of these improvements was a decrease in downtime of 39 minutes 48 seconds and the improvement efficiency achieved was 81.2%.

Overcoming Barriers Associated with Oral Delivery of Differently Sized Fluorescent Core-Shell Silica Nanoparticles.

Oral delivery, while a highly desirable form of nanoparticle-drug administration, is limited by challenges associated with overcoming several biological barriers. Here, the authors study how fluorescent and poly(ethylene glycol)-coated (PEGylated) core-shell silica nanoparticles sized 5 to 50nm interact with major barriers including intestinal mucus, intestinal epithelium, and stomach acid. From imaging fluorescence correlation spectroscopy studies using quasi-total internal reflection fluorescence microscopy, diffusion of nanoparticles through highly scattering mucus is progressively hindered above a critical hydrodynamic size around 20nm. By studying Caco-2 cell monolayers mimicking the intestinal epithelia, it is observed that ultrasmall nanoparticles below 10nm diameter (Cornell prime dots, [C' dots]) show permeabilities correlated with high absorption in humans from primarily enhanced passive passage through tight junctions. Particles above 20nm diameter exclusively show active transport through cells. After establishing C' dot stability in artificial gastric juice, in vivo oral gavage experiments in mice demonstrate successful passage through the body followed by renal clearance without protein corona formation. Results suggest C' dots as viable candidates for oral administration to patients with a proven pathway towards clinical translation and may generate renewed interest in examining silica as a food additive and its effects on nutrition and health.

Correlated Single-Molecule Magnetic Tweezers and Fluorescence Measurements of DNA-Enzyme Interactions.

Combining force spectroscopy and fluorescence microscopy provides a substantial improvement to the single-molecule toolbox by allowing simultaneous manipulation and orthogonal characterizations of the conformations, interactions, and activity of biomolecular complexes. Here, we describe a combined magnetic tweezers and total internal reflection fluorescence microscopy setup to carry out correlated single-molecule fluorescence spectroscopy and force/twisting experiments. We apply the setup to reveal the DNA interactions of the CRISPR-Cas surveillance complex Cascade. Single-molecule fluorescence of a labeled Cascade allows to follow the DNA association and dissociation of the protein. Simultaneously, the magnetic tweezers probe the DNA unwinding during R-loop formation by the bound Cascade complexes. Furthermore, the setup supports observation of 1D diffusion of protein complexes on stretched DNA molecules. This technique can be applied to study a vast range of protein-DNA interactions.

Accurate Sphingolipid Quantification Reducing Fragmentation Bias by Nonlinear Models.

Quantitative sphingolipid analysis is crucial for understanding the roles of these bioactive molecules in various physiological and pathological contexts. Molecular sphingolipid species are typically quantified using sphingoid base-derived fragments relative to a class-specific internal standard. However, the commonly employed "one standard per class" strategy fails to account for fragmentation differences presented by the structural diversity of sphingolipids. To address this limitation, we developed a novel approach for quantitative sphingolipid analysis. This approach utilizes fragmentation models to correct for structural differences and thus overcomes the limitations associated with using a limited number of standards for quantification. Importantly, our method is independent of the internal standard, instrumental setup, and collision energy. Furthermore, we integrated this method into a user-friendly KNIME workflow. The validation results illustrate the effectiveness of our approach in accurately quantifying ceramide subclasses from various biological matrices. This breakthrough opens up new avenues for exploring sphingolipid metabolism and gaining insights into its implications.

Menurunkan Waktu Penggantian Tabung Gas Welding (GMAW) Menggunakan Metode Single Minute Exchange Die (SMED) di Politeknik Astra

Politeknik Astra is a high vocational education institution that have several laboratories. Welding laboratoy has longest preparation time compare to another laboratories. Gas cylinder changes process in Gas Metal Arc Welding (GMAW) takes 29.2 minutes, which is the longest preparation time so the welding training is hinder by it. Previous condition of gas instalation is, every GMAW machine equiped with one gas cylinder, so if the cylinder is run out of gas, it have to changes and potentially it could be done more than one machine. The aim of this research is to reduce gas cylinder changes time in welding laboratory using single minute exchange of dies methode (SMED). SMED is one of lean manufacturing metodes that able to identified and reduce or eliminate time waste by separated internal setup and external setup. Using SMED metods, gas cylinder changes activities are identified then divided by internal and external setup. The activities that have no effect to gas flow from cylinder to machine are convert from internal to external setup. For the final, external setup are simplified using 5W2H tools. The solution that reserearcher found using SMED method is to built a centralized gas system with one cylinder as an active gas supply for whole GMAW machine and the other one as a backup cylinder, in stead of install gas cylinder on every GMAW machine. The result of this research is setup time for gas cylinder changing process is reduce from 1752 seconds or 29.2 minutes to 877 seconds or 14.6 minute or reduce 50%, furthermore man power alaso reduce from 3 person to 1 person.

Air entrapment at impact of a conus onto a liquid

In this experimental work, a conus impacts a deep liquid pool at a speed varying from 1.3 to $19.0\ {\rm cm}\ {\rm s}^{-1}$ . Two liquids (2.5 % butanol–water solution or distilled water) and four coni made from duralumin with a diameter of 180 mm and different deadrise angles $\beta$ ( $2^{\circ }$ , $3^{\circ }$ , $4^{\circ }$ and 5 $^{\circ }$ ) are tested. An air cushion is trapped between the conus solid surface and the liquid. Several types of bubble patterns after the collapse of the air cushion are observed: one or multiple bubbles near the conus centre (vertex), irregular trails of bubbles on the conus surface and a ring of bubbles in a ‘necklace’-shaped arrangement. With a total internal reflection set-up and appropriate image post-processing, the external and internal radii of the ring-shaped wetted area are estimated for each frame. The external (internal) radius increases (decreases) in time following a linear (exponential) law. The speed of the outer border of the wetted area is in agreement with the Wagner theory for a body impacting onto a liquid. The initial radius of the annular touchdown region is estimated as the intersection of the relevant fitting curves. In the studied range of parameters, the initial radius obeys a universal scaling law, which follows from the air–water lubrication–inertia balance.

ANALISIS PENURUNAN WAKTU SETUP DENGAN MENGGUNAKAN SINGLE MINUTE EXCHANGE OF DIE UNTUK MENINGKATKAN PRODUKTIVITAS PADA AUTOMATIC MOULDING MACHINE

PT XYZ is a company that has been engaged in metal casting for a long time. This company produces products in the form of wingnut spare parts. The production system used is make to order production. The obstacle faced by PT XYZ was that it was found that the setup operation process activity took quite a long time on average 40 minutes. If it continues to occur it will have an impact on delays. With these problems, PT XYZ reduced the setup time to overcome delays in completing the automatic molding machine wingnut product. Utilize the Single minute exchange of die (SMED) method to speed up setup. The SMED approach distinguishes between internal regulatory and external regulatory activities. Adjustment activities that only Internal adjustments can be made while the machine is stopped. The External Setup setup activity can be performed while the machine is running or operating. By switching to external setup instead of internal setup, setup tasks that were completed when the machine was stopped can now be completed while it is running, thereby reducing setup time. the setup operation of all these activities is carried out when the engine is off or the internal setup produces an average of 101 molds. Meanwhile, the setup time after implementing SMED can be reduced to 26.78 minutes or a decrease of 47.61%. This decrease in setup time increases productivity by 2 molds/day and if in a month with 26 working days it can add 59 molds so that in total it can produce 159 molds/month.

Carrier Concentration Analysis in 1.2 kV SiC Schottky Diodes Under Current Crowding

Die-level current crowding phenomena are analyzed at the microsecond timescale with an internal IR-Laser Deflection set-up. To this end, the 4H-SiC plasma-optical coefficient for the refractive index is reported for the first time. A SiC Schottky diode with an edge termination based on a junction termination extension is used as a test vehicle. Under biasing conditions, the edge termination starts a local bipolar conduction along the device active area perimeter, leading to current crowding effects. Using refractive index measurements, a depth-resolved carrier profile is extracted and assessed using both, simulation and Free Carrier Absorption measurements.

Knowledge Practices Within and Beyond Sharing and Commoning Urban Initiatives

In the context of neoliberal cities, with growing levels of housing commodification and space competition, sharing and commoning urban initiatives within the larger framework of urban social movements are shaping tactics of contestation. To what extent they represent sustainable efforts to urban commons governance remains largely unexplored. This article aims therefore to contribute to better understand how practices of solidarity can be maintained beyond their first productive phase and to explore the engagement of social movement and initiatives actors in the production and maintenance of shared spatial resources. To do that, we focus on knowledge practices as a key factor to ensure sustainability of actions within and beyond urban initiatives that engage with and practice sharing and space-commoning. Drawing on figurational sociology, we consider individuals involved in these urban initiatives as embedded in multiple social settings and networks of collaboration and interdependence, in which transactions such as resources, ideas and information take place giving way to collective action, new modes of participation and urban transformation. Within this conceptual framework, we explore how urban initiatives networks produce and transfer their knowledge (1) within their own internal set-up, (2) to private and public institutions (e.g., administration and political actors) and (3) to other civil society organizations. To do so, we draw on qualitative research conducted in three German cities, Kassel, Stuttgart, and Berlin on the topics of sharing and commoning practices in the field of housing and public space. By looking at the practices by which knowledge—required for action and networking—is co-/re-produced and exchanged, we identify those that constrain or enable sharing and commoning strategies on the long-term and have therefore a larger potential for sustaining efforts of urban commons governance.

Microcosm of Ecologic Taxation in Russia

The article analyzes wordings of the category ‘ecosystem’ as a form of interaction in economics. Drawbacks of the current definitions of the term were identified and the wording of the category ‘ecosystem’, which is the most substantiated for the present research, was presented. The term ‘microcosm of ecologic taxation’ was introduced and defined. Common features and differences, the structure, elements and the internal set-up of the ecosystem and microcosm were described. The author underlined the strategic importance of the ecosystem approach in view of possible evolution of the ecosystem (microcosm) value (principle idea) in conditions of instability, the place of microcosm of ecologic taxation was identified in the economic system of Russia. The key part in microcosm being studied is assigned not to economic entities and administrative agents but to the network of interrelations, tools and control levers integrating them. The forms of its actors’ interaction are shown, i. e. persons united by their involvement in ecologic tax payment (beneficiaries, tax payers and bearers). The idea and definition of the cluster as an association underlying microcosm were given. The cluster was shown as a complicated association of simple entities of economic relations, working in similar social-demographic, climatic and natural-resource conditions. The cluster structure was depicted as an element of the structure of ecologic taxation microcosm. The article substantiated the possibility to use microcosm of ecologic taxation as a management tool aimed at providing ecologic security of the country.

Impact Evaluation of The Internal Control System on The Sales Function Performance Within Moroccan Companies’ Context

Moroccan business leaders are increasingly concerned about the phenomenon of declining commercial activity, confirmed by the economic barometers published by the General Confederation of Moroccan Enterprises (CGEM) during the last four years (2015-2018), and the direct causes that might be linked to unfair competition, payment delays problem, unpaid debts and finally the widespread of a heavy informal sector. Through this article, we are going to focus on the relationship that may exist between the components of an internal control system setup in a sales function and its performance. In other words, we are looking to explain the decreasing performance of the sales function using the evaluation of the internal control system deployed there. To do this, we will present in the first part, the theoretical foundations of the internal control system and socio-economic performance. Then, we will analyze the points of connection and influence to finally develop some hypotheses, which will be the subject of an empirical study based on of one hundred and sixty-one Moroccan companies. The results of our work provide an answer on the degree of influence of internal control system components of the commercial function on its socio-economic performance and more precisely on its commercial performance.

How to minimize litigations and medical malpractice claims during ophthalmic practice?

The health profession is considered to be one of the noblest professions in the world. While Indian medical infrastructure is being noticed and praised on the global map, on the contrary, the doctor-patient relationship is deteriorating, our internal medical setup is facing extensive problems with consumer cases/medical litigation fast becoming one of the most serious of all issues. The number of cases against ophthalmologists for malpractice is increasing. While very few cases may be legitimate and based on clinical negligence exercised by the doctors, most medical professionals are wrongfully accused because of the lack of public understanding. The eye care professionals must communicate empathetically, emphasize diligent service delivery and also maintain proper records about the patient history, examination, consent, treatment and follow-up, and referral. Eye camp surgery should be done only in the operation theater of the hospital set up and the permissible number of cataract-IOL surgery can be done following all checklist/protocols and precautions. Lawsuits for medical negligence in ophthalmic practice can be minimized or avoided by following surgical checklists, protocols, proper documentation (maintaining medical records), taking informed consent, communication about the cost and outcome of the procedure or treatment, timely referral of the patient (in case of any complication), and obtaining adequate professional liability insurance.

Transnational Policy Networks and Change Through Internationalization (The Record of Project 5-100)

This article considers the ideational and political contexts in which Project 5-100, the Russian excellence in higher education initiative emerged, as well as the specificities of its organisational and behavioural model. While Project 5-100 has been studied in the academic literature as regards its efficiency and how it affected the performance and inner workings of the participating universities, the question of how the project came about and the characteristic traits of its internal set-up still remain largely overlooked. The study focuses on the involvement of local and international players, arguing that their successful and organic cooperation influenced both the architecture and the implementation of the project. This paper contributes to the literature on policy networks by showing that transnational actors do not necessarily undermine or challenge state power and can on the contrary help governments implement systemic change. Inspired by the international experience of establishing world-class universities, Project 5-100 was conceived and lobbied by a small but influential group of visionaries pushing for change who – acting in a concerted and purposive manner – acquired a novel and powerful capacity to use international expertise for the development of a key national project, capable of deeply transforming the country’s higher educational system.

АГІЛЬНІСТЬ КОМПАНІЇ ЗА ЇЇ МЕЖАМИ

Companies often rely on the Know-How of external service providers for the development of software and solutions. Modern forms of working and collaboration change the development of products and services at the same time. How do these trends influence the cooperation and collaboration between companies and their external agile service providers? The purpose of this academic work is to figure out which steps companies have to take to implement agile working and collaboration with external service providers. Therefore, a case study, including a qualitative survey, was used to find and point out which measures and actions companies have to take, to accomplish the goal of an effective implementation of an agile collaboration and cooperation. Three core issues were identified, on which basis the research questions regarding the measures will be answered: First, which possibilities companies have, to implement an internal agile setup to collaborate with agile service providers on an equal basis. Second, which contract variants can support and improve the agile cooperation and third, which agile techniques and methods should be used in the agile collaboration. The case study results confirm the assumption, that the three identified core issues are essential for an effective cooperation in the agile environment. While it was verified on the one hand that contract requirements changed concerning their flexibility and adaptability, it was also verified on the other hand, that the internal setup require agile drivers, techniques and methods to enable an effective cooperation with agile service providers. This article gives an overview of the most important content within the three stated core issues and also gives companies advises on how to build a basis for an effective cooperation.
