Introduction
Sustainability is a broad discipline, giving students and graduates insights into most aspects of the human world from business to technology to environment and the social sciences. Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The ability to sustain something for an indefinite period of time, without depleting the resources used to sustain it, and such that it does not damage the surroundings (environment) in which it resides. The definition of “sustainability” is the study of how natural systems function, remain diverse and produce everything it needs for the ecology to remain in balance. It also acknowledges that human civilization takes resources to sustain our modern way of life. There are countless examples throughout human history where a civilization has damaged its own environment and seriously affected its own survival chances. Sustainability takes into account how we might live in harmony with the natural world around us, protecting it from damage and destruction.
Due to ISO 14040.2 Draft: Life Cycle Assessment - Principles and Guidelines, Life Cycle Assessment (LCA) is a technique for assessing the potential environmental aspects and potential aspects associated with a product (or service) by:
- compiling an inventory of relevant inputs and outputs,
- evaluating the potential environmental impacts associated with those inputs and outputs,
- interpreting the results of the inventory and impact phases in relation to the objectives of the study.
To simplify it, Life Cycle Assessment models the complex interaction between a product and the environment from cradle to grave. For an information, the Life Cycle Assessment is also known as Life Cycle Analysis or Eco-balance. Life Cycle Assessment is have a lot of benefits. They are quantify environmental benefits of products, provide credible evidence for marketing claims, identify opportunities to improve the environmental performance of products at various points in their life cycle, inform decision‐makers in industry, government or non‐governmental organizations and also instill life cycle thinking within businesses.
Objectives of The Study
The Sustainability Assignment is actually to teach students in how to improve the sustainability of the product. Besides, students also can learn about the definition and the important of the sustainability. To undergo the sustainability process, one of the stationary at the market has been choosing, which is Two Holes Puncher. The puncher has been redesign in shape, size, materials used and way of function to make it more sustainable.

Material Analysis
Materials analysis is necessary to characterize and evaluate the quality and performance of materials. It supports innovation in industries such as engineering and manufacturing. Materials such as polymers, plastics, composites, metals, alloys, ceramics, paper and board have diverse properties that impact performance, therefore an understanding of your material’s properties is essential to determine if your material or product is suitable for its intended use or to rectify a failure.
Discussions
A Hole Puncher is one of the stationary that is commonly refers to the office tool. It is used to create holes in sheet paper, which is for the purpose of collecting the sheets in a binder or folder. Besides a Hole Puncher also can be refer to tools of different construction from one designed of paper. The those used are examples for the leather goods ( which generally called as a leather punch ), for cloth, for thin plastic sheeting, and also for variations of sheet metal, such as aluminum siding or metal air ducts. At the market outside, there are many kind of Holes Puncher, which are Single Hole Punch, Eyelet Punch, Multiple Holes Punch and Paper Drill. For example of Multiple Holes Puncher is Two Holes Puncher. Two Holes Puncher is choose to be used to undergo the sustainability process. The puncher chosen consists of Top Body, Bottom Body, Support Bases, Cover, Bolts and Rods.
In finishing the sustainability process, Two Holes Puncher has been redesign in shape, size, materials used and way of function to make it more sustainable. The Top Body of the Two Holes Puncher that has been chosen is been redesign in it shape, which is an oval hole is applied on it. Besides, the thickness of the cover is reduced from 6mm to 4.5mm. The sustainability of the product is measured by comparing the material used to make the Top Body, Bottom Body and Base Supports material, which are Carbon Steel Sheet, Annealed Stainless Steel and Stainless Steel Sheet.
Based on the comparisons of the design of the both Two Holes Punchers, the Redesign Two Holes Puncher is better. This is because the environmental impact of the Carbon Footprint, Total Energy Consumed, Air Acidification and the Water Eutrophication for the redesign puncher are higher than the original one. For example, at the Carbon Footprint, the environmental impact of material for redesign puncher is 1.3kg CO2e while for the original puncher, the environmental impact of material is 0.688 CO2e. So, it is true that the size and the shape of the any product effect it sustainability.
By comparing the materials used by the Two Holes Punchers, the Carbon Steel Sheet and the Annealed Stainless Steel are both the better materials compared to the Stainless Steel Sheet. The environmental impact of the Carbon Footprint, Total Energy Consumed, Air Acidification and the Water Eutrophication for the Carbon Steel Sheet and the Annealed Stainless Steel are sharing the same values, which are mostly higher compared to the Stainless Steel Sheet. Due to the results, we can know that the differences in materials of any product will effect the sustainability value of the product even though the size and the shape are same.
Therefore, the Redesign Two Holes Puncher with the Carbon Steel Sheet or the Annealed Stainless Steel material is the recommended puncher. This is because the puncher is better in sustainability, so that it will give benefits to the environment, society and economy.
Conclusions
Sustainability is actually used to describe many different approaches toward improving our way of life. There are some views of sustainability. Sustainability means reducing our harm on environment and ultimately reversing the harm we have already caused. Besides, sustainability means renewing resources at a rate equal to or greater than the rate at which they are consumed. Furthermore, sustainability can be definition as taking the long term view of how our actions effect generations and making sure we don’t deplete resources or cause pollution at rates faster than the earth is able to renew them.
From the result, I can analyze that the materials used, the shapes, the size will effect the sustainability of the product. Every changes make will effect the end life of the product. Besides, I can conclude that sustainability is occurring when environment, society and economy are thriving. A healthy economy is actually depending on a healthy society, while both of which rely on a healthy environment.
There are many benefits that can be obtain from the sustainability process. First is environmental sustainability. The environmental sustainability is actually good for financial. An intelligent approach to environmental sustainability that incorporates investor demands can help future-proof investment and engagement from shareholders. Besides is the environmental sustainability is also can manage risks and increase the opportunities to growth in business , which is not just in terms of improved financial performance but also from attracting and retaining the brightest talent and increased levels of innovation. Second is sustainable society. Sustainable society is the one that can continue indefinitely. Its level of consumption reflect environmental and resources balance. It assure its citizens equality, freedom and a healthy standard living thing. The economic sustainability the ability to support a defined level of economic production indefinitely.
So, in the nutshell, everyone should be build the sustainability style in their life encourage toward the environmental, society and the economic. Therefore, I am encourage all to emphasis in apply the sustainability in their life since there are many advantages that can help our own self.
