Abstract:
In trading activities, especially exports in the food commodities sector, several documents must be made and completed by exporters, such as Certificate of Quality, Test-Certificate, and Chemical Analysis. Balai Pengujian & Sertifikasi Mutu Barang Makassar is a government agency operating in South Celebes that tests the quality of various agricultural and plantation commodities. From year to year, demand for testing services has increased along with the number of exports. So, testing activities have changed in terms of facility layout requirements resulting in overwhelmed in carrying out the testing process. Test rooms are not connected based on the current testing flow causing the tester’s ineffective work patterns. This study aims to redesign the layout of the facilities in the testing laboratory with the Kaizen approach to support the smooth testing process. The results of this study indicate that the proposed floor area uses a 150% allowance so the calculation requires a floor area of 42.52 m2 . After that, an analysis of the proximity of the facilities is carried out by making ARC (Activity Relationship Chart) and ARD (Activity Relationship Diagram). Based on ARD, a template is made for the layout of testing laboratory facilities. This study applies Kaizen theory with the 5S concept to obtain a neater design, namely Seiri and Seiton in the refreshment laboratory and weighing room, Seiso on testing equipment in all testing laboratory rooms, Seiketsu and Shitsuke applied to all rooms in the testing laboratory.

Abstract:
As after sales services become more and more popular, particularly preventive or corrective maintenance, the intervention and repair of the customer’s goods in a timely and efficient manner ensure customer satisfaction and contribute to the establishment of brand image in the market of the suppliers. The availability and quality of spare parts are key elements of this strategy while ensuring minimal management costs. The reuse of spare parts retrieved from customer systems is a growing maintenance strategy practice which impacts the traditional spare parts supply chain. This reuse is primarily driven by extending the economic life of goods, initially regarded as waste and therefore without added value, by transforming them into valuable spare parts that can be reused; secondly, for environmental or regulatory reasons, demanding responsibility for the treatment of products at the end of their life; and thirdly, to improve the availability of parts for maintenance, especially parts that the organization can no longer purchase or that are impacted by other issues. It also involves the analysis of their condition and their eventual return to working order as they are retrieved from the customer’s systems in a defective condition. In this paper, we will identify and classify the different customers and spare parts by estimating the critical level of rationing policy based on forecasts, identify the thresholds of inventory management policies, and finally, compare the different policies by service level and inventory level performance for the N.A.C.C. company.

Abstract:
The demanding market shows that the need for the disabled vehicles have been increasing over the recent years. However, these factory setting cars are pricey, and its buy-sell process is time-consuming. These cars also are not meant as a universal design or inclusion design type of car, so that when it is designed for the disabled, it can be beneficial for all. With the motivation to include limbs disabled drivers in designing a universally designed car, this study aims to determine the preferred ergonomics interior of the car which can improve features needed to meet the mobility of impaired individuals in most scenarios. 5 simulations were carried out to simulate these conditions using the RULA analysis, in order to simulate the ergonomics impact on the manikin. In the final analysis, the simulations showed a virtuous score, which was between 1 and 2 for the newly redesigned interior, compared to the score of 3 to 6 for current cars. Another verification made, post questionnaire delineates positive responses upon the redesigned parts scoring 70%~90% level of ergonomics rated. Therefore, this research has set forth the necessity of redesigning a car interior and improved its ergonomic features extensively, specifically for lower limb and combined limb disabled drivers.

Abstract:
The primary intent of the current research is to provide insights regarding the management of spare parts within the supply chain, in conjunction with offering some methods for enhancing forecasting and inventory management. In particular, to use classical forecasting methods, the use of weak and unstable demand is not recommended. Furthermore, statistical performance measures are not involved in this particular context. Furthermore, it is expected that maintenance contracts will be aligned with different levels. In addition to the examination of some literature reviews, some tools will guide us through this process. The article proposes new performance analysis methods that will help integrate inventory management and statistical performance while considering decision maker priorities through the use of different methodologies and parts age segmentation. The study will also identify critical level policies by comparing different types of spenders according to the inventory management model, also with separate and common inventory policies. Each process of the study is combined with a comparative analysis of different forecasting methods and inventory management models based on N.A.C.C. parts supply chain data, allowing us to identify a set of methodologies and parameter recommendations based on parts segmentation and supply chain prioritization.

Abstract:
This report illustrates how management accounting can be used in helping an organization reach sustainability by applying four main tools in management accounting to a dairy company. These tools are LifeCycle Analysis, Identification of Relevant Costs, Activity-Based Costing (ABC) System and Balancing Score Card, all of which can help qualify and consequently quantify the various costs (including environmental costs) incurred during the operation of a company. Besides that, the above tools can also be utilised in a company’s decision-making processes by the man-agement team. Thus, it is suggested that companies integrate these tools into their reporting system. This report illustrates the definition of a sustainable organization in the beginning, followed by detailed descriptions of the four management accounting tools, together with their applications to a diary company. The report ends with a summary on which type of role each tool plays in the re-porting system.

Abstract:
Continuous changes in vehicle technology, road condition, traffic compositions initiate the change or updating of road users’ cost models. So that it needs to practice a continuous revision or update periodically for realistic estimation of costs and benefits. This paper presented the relationship and comparison between road users’ cost along Addis Ababa-Adama newly constructed expressway using the Highway Development and Management (HDM-4) Software and manually using formulations developed in the Portuguese model. The method started with data collection. All input data were collected from primary and secondary sources. The primary data utilized an interview, and secondary data were sourced out from pertinent documents, both published and unpublished. More data were gathered that related to vehicles. The vehicles using the road are classified based on the manual from the Ethiopian Road Authority as cars, utilities, small bus, large bus, small truck, medium truck, heavy truck, and truck trailer. The collected data have been input into the HDM-4 interface; the output of the analysis was vehicle operating costs, travel time, and road users’ cost as a summation. Using manual technique and HDM-4 Software, Birr 128.62/km/vehicle and Birr 139.23/km/vehicle, respectively, were found from road users’ costs analysis. The result shows the difference of Birr 10.61. Also, the correlation coefficient of 0.75 is determined, which shows that the two results of road users’ costs are highly related. As a result, the study reveals that the application of HDM-4 Software and the manual technique formulations from the Portuguese model can be adopted interchangeably to calculate Road Users’ Cost of road sections in Ethiopia. Hence, the study results are expected to be an eye-opener for a future similar project by the concerned agencies.

Abstract:
There are different ways to examine and explain a study and its findings based on using numbers as a measure, a descriptive style, or a mixture of both. These three research approaches are quantitative, qualitative, and mixed methods that are commonly used by researchers in various research studies. However, with many options regarding the research design, it seems challenging for researchers to select the most appropriate approach based on the study and realize differences. This study provides a comprehensive review of qualitative, quantitative, and mixed-method research methods. Each method is clearly defined and specifically discussed based on applications, types, advantages, and limitations to help researchers identify select the most relevant type based on each study and navigate accordingly.

Abstract:
The choice of the environmental risk management instrument to be used within the scope of corporate governance in companies is of paramount importance to avoid or mitigate the triple environmental responsibility to which they are exposed. In this sense, the following research problem arises: The Environmental Impact Assessment (EIA), an instrument of the National Environment Policy and a model of environmental risk management adopted by some companies, proves to be efficient, effective and effective for the fulfillment of the duty to protect the environmental balance and, therefore, for sustainable development? The present study aims to elucidate this research problem. To this end, analyzes were carried out on risk and environmental damage, from a perspective of the socioenvironmental function of companies today; the need for a new posture by companies in view of the reflexes of environmental risks in business activity; and the question of the adequacy or inadequacy of the EIA as an instrument of the National Environment Policy and as a model for managing environmental risks and damages, in the pursuit of sustainable development. The method of approach used was the deductive one, and the research was carried out using the method of bibliographic procedure, through which research was carried out on books, scientific articles and legislation. The result points out the inefficiency and ineffectiveness of the EIA for the management of environmental risks and, thus, for the fulfillment of the duty to protect the environmental balance by companies.

Abstract:
Denim was produced in the city of Nîmes in France and was originally called the serge de Nîmes. The word denim is an English colloquialism of the French term: “denim.” Day by day Bangladesh denim sector very much developed and helps to increase productivity. Bangladesh have seen a significant increase in investing in denim fabric manufacturing, increasing the country’s production performance by reducing fabric dependence on imports. It is important due to its aspects of durability, and not easily torn which benefited physical laborers much. The government also plays a vital role in denim textile industry. This paper shows different section of denim textile industry such as: sewing section, cutting section, washing, IE and finishing department. The main aim of this paper is how to role all the section of denim textile industry. Textile education is insufficient without industry attachment, which bridges the gap between theoretical and practical aspects and acclimates students to the industrial world. We can gain about theoretical development on an industrial level from this attachment. We can understand more about the machines used in various departments, their technical specifications, characteristics, operating system, and so on, and we believe that without this type of industrial connection, it is impossible to obtain industry-based information about textile engineering adequately. The Industrial Attachment on Denim Manufacturing Technology was used to organize this study (sewing section, cutting, IE, washing section, CAD Section, and finishing department. Various operating procedures for the production of denim in the industry are presented in this paper. The technique and process of several procedures and processes are presented here such as machine specifications, manpower, maintenance, layout of the different section, dye processes and wet processes.
