A REVIEW ON OPTIMISTIC IMPACT OF CLEANER PRODUCTION ON MANUFACTURING SUSTAINABILITY

As a continuous application of an integrated environmental strategy, Cleaner Production (CP) is seen to have a substantial impact in establishing a sustainable manufacturing system. Thus, this paper explores and discusses intensively the impacts and benefits gains from the CP implementation that influences the sustainability development. The findings show that CP have optimistic impact on manufacturing competency, environment and economics performance which considered most significant influence on sustainability. Besides, economic performance was identified as an ultimate goal in manufacturing sustainability that can be enhanced significantly by competency and environmental performance. This paper provides the correct translational process of CP in order to achieve high level of sustainable manufacturing practice included the specific characteristics of performances. It can be referred as a guideline for manufacturing firms to define and measure performance based on CP implementation

EXPERIMENTAL INVESTIGATION OF DRILLING PROCESS USING NANOFLUID AS COOLANT

Nanofluid coolant is one of the new formulation of cutting fluids used in machining in order to obtain better surface finish of products. In this study, the effect of various coolants (nanofluid and pure deionized water) and cutting parameters (cutting speed and feed rate) to the machining performances of titanium alloy was investigated by using drilling process. A series of experiments were conducted using Design of Experiment (DOE) and the machining performances were measured in terms of surface roughness and cutting temperature. The results show that better surface finish and lower cutting temperature can be obtained by using carbon nanofiber nanofluid compared to that of pure deionized water. The significant factors that influence the surface roughness of titanium alloy are feed rate and coolant. Coolant also plays an important role to reduce the cutting temperature during the drilling process

THE EFFECT OF ASSEMBLY DESIGN PARAMETERS ON ASSEMBLY TIME

Reducing cycle time has an impact in many aspects such as productivity and capacity of industry. This study investigate the effect of assembly design parameters such as workstation design, working posture: standing and sitting and jig design on plug assembly time. The parameters or factors involved were three jig designs; number of holders, working postures: standing and sitting to assembly time and gender. An experiment with a full factorial design with four factors of 2 and 3 levels was applied. Ten participants consisting of five males and fives females were asked to assemble the plugs. The study concluded that all main factors, and some interaction factors significantly contributed to assembly time. The lowest assembly time per plug for assembly setting was sitting posture by male operators , using rectangular jig with 3 holders per jig. Meanwhile the highest assembly time per plug was performed by the female operator using horizontal jig with 5 plugs holder per jig. The study also generates the regression model that describes the relationship of all factors involved. Validation of the model also was performed by taking some runs of experiments. The average deviation of actual data and predicted is less than five per cent

HELICAL MICRO-HOLE DRILLING OF CHEMICALLY STRENGTHENED GLASS USING CAPSULE-SHAPED ELECTROPLATED DIAMOND TOOL

This study investigates the micro-hole drilling performance of chemically strengthened glass plate by using a capsule-shaped electroplated diamond tool and the helical drilling method. Three different helical pitch conditions were tested to drill holes with a diameter of 1 mm. The number of drilled holes, grinding force, and maximum crack size were measured along with the observation of the drilled holes to evaluate the performance of the micro-hole drilling. From the experimental results, it was found that as the size of helical pitch decreased, the number of drilled holes increases where the average grinding force generated becomes smaller. By using small helical pitch condition, 43 holes could be drilled but the maximum crack size generated at the outlet side of the drilled hole is not able to achieve the high-grade quality compared to the inlet side. The resultant grinding force generated when the tool tip nearing the outlet side of the glass plate has caused the large crack at a certain position on the outlet side

Kota Bharu Islamic City – The Concept of a New Cultural Tourism Product

This study introduces the concept of the Kota Bharu Islamic city in the eyes of tourists, with focus on recent trends affecting Malay cultural landscape and urban planning issues in Kelantan. The aims of this study are to introduce the concept of the Kota Bharu Islamic City as the new cultural tourism product in Malaysia as well as to enhance the reputation of the concept at the highest peak and Malay community development in Malaysia by using multiple methods including literature review, site observation and document analysis. The Kelantan Malay heritage should be highlighted as a main consideration in the future planning to avoid further damage or loss of valuable heritage. Finally, a regional vernacular tradition should be set as the focal point in making of the Islamic City of Kota Bharu without mimicking from other Islamic countries and subsequently the concept of the Kota Bharu Islamic City to be promoted as a new cultural tourism product in Malaysia will be successful

A FRAMEWORK OF UT-UTeM MOBILITY PROGRAM BASED ONDIGITAL ENGINEERING AND DETERMINISTIC DESIGN

The University of Tokushima (UT) and Universiti Teknikal Malaysia Melaka (UTeM) have concluded an academic partnership under the academic agreement of MOU/MOA in 2013. As one of the joint activities for the agreement, a mobility program was initiated as MMPT2013 and the mobility students of UTeM joined the CEL Summer Program (CELSP) at UT in 2013. This paper presents the framework of CELSP based on an approach of digital engineering and deterministic design. The idea of this approach was derived from SCW project based on the historical design of a stair-climbing wheelchair. The design was made before the proposal of deterministic design and even before the birth of computer-aided design software (CAD), or one of the very popular digital design tools today. Reviewing SCW project from deterministic design point of view using a digital engineering approach, this paper overviews CELSP and shows how this approach was applied to one of the sessions of CELSP

Cleaner Production Implementation In An E-Waste Recovery Plant By Using The Value Stream Mapping

This study aims to determine the manner in which the Cleaner Production (CP) sustainability measures would be embedded into the altered Value Stream Mapping (VSM), which is a Lean Manufacturing tool. The typical VSM technique does not consider the societal and the environmental metrics that are imperative for determining the sustainability for any production line. Additionally, the Guidelines for Green Industry Auditor, 2014, published by the Department of Environment, Malaysia, have made no mention regarding the proper lean tools which need to be applied to the audit systems as per the USEPA for improving the system. The VSM ability to determine the environmental, economic and societal performance would help VSM be a useful tool. Also, many companies can apply the data generated in a better manner and change their operations to fit the technology for improving the manufacturing. This paper has presented a CP implementation with the help of a VSM technology, based on the earlier literature. One pilot case study has been conducted in the local e-Waste Recovery Plant, ABC Sdn. Bhd., which demonstrated that this VSM approach, could capture the environmental, economic and societal sustainability for a specific process and has also, recommended some future researches
