Abstract

The concept of a circular economy began to be launched worldwide due to the impact of increasing sustainability. The advancement of technology certainly makes it easier to implement a circular economy, especially in Industry 4.0. Several industries have implemented the concept of industry 4.0, but implementing a circular economy in the industry has yet to go well. The problem is that there needs to be a measurement of the circular level of the industry. This study aims as a literature study on determining the formulation of the circular economy index. The existence of gathering perspectives from various countries is expected to provide the application of the indicators that have the most influence on the measurement of the circular economy.

Abstract

Circular Economy (CE) right now has been a point of interest among countries in the world as a commitment of the Paris Agreement to solve global environmental problems, which are simultaneously beneficial to economics. However, presently there is no single indicator available that easily be used as a CE standard due to various stresses among the countries. There are different approaches among countries in developing CE indicators, although they are still within the scope of the environmental and economic aspects. CE indicators could be developed based on region covering several countries, government/country level, and company level. Those indicators refer to the region and government policy and market or users of the product and a society where its public area would receive waste that the company might produce. This review will discuss only European Union and Poland, representing regions and countries. A region like the European Union (EU) considers ten indicators for CE, consisting of 21 sub-indicators. These indicators include self-sufficiency in raw materials, procurement for the green public, waste generation, food waste, recycling rate, recovery of specific waste streams, recycled materials to raw materials demand contribution, raw material trade-in, investment, jobs, and gross value-added, patents of secondary and recycling raw materials. While Poland, as a member of the EU, developed 25 CE indicators based on the seven dimensions of the economic point of view, such as economic prosperity, zero waste, innovative, renewable energy- based economy, low carbon, smart economy, and spatially effective economy. Implementing a Comparative Analysis Method that compares one indicator to another, the results show that 6 of 10 indicators belonging to the EU overlap with four indicators of 25 belonging to Poland. Covering all indicators of both regions and countries, thus it would become 29 selected indicators that might be useful for developing Indonesia CE- Indicators, which are presently unavailable yet.

Abstract

In the context of resource scarcity and food energy security in the midst of increasing food demand, the circular economy (CE) is a promising strategy to address the sustainable use of resources. This article aims to propose measurement elements in raw materials with recyclable concepts in implementing CE in the food and beverage industry. However, the CE framework has not been adapted to the needs of the Food And Beverages Industry. This article attempts to address this gap by analyzing the range of available indicators to measure trade in recyclable raw materials, namely by looking at the difference between the value of exports and imports. Thus, the differences in the CE framework can theoretically be adapted to the production system in the Food And Beverages Industry. So that the implementation of CE can be implemented in accordance with its functions, strategies and principles in managing a business model that replaces the concept of "end of life" by recycling raw materials which aims to create a quality environment, economic prosperity and benefits for future generations.

Abstract

This research aims to determine the design specifications for tea drink packaging that appeal to consumers using Kansei and eye-tracking techniques. Kansei Engineering focuses on developing products that align with consumers' feelings and emotional needs. Eye-tracking provides insights into how consumers see and interact with packaging, as evidenced by total fixation duration, allowing for the identification of design elements that attract the most attention and influence consumer perception. The application of eye-tracking and Kansei Engineering helps match customer perceptions of products with their functional and technical specifications, providing a holistic and effective approach to increasing sales and consumer satisfaction. Integrating these two methods makes the design process more consumer-focused, combining emotional and visual appeal, thereby increasing attractiveness and potential consumption. The urgency of this research lies in its potential to revitalize the tea industry in Indonesia by utilizing innovative packaging designs. Enhancing consumer appeal to tea products through the integration of Kansei Engineering and eye-tracking, which are visually and emotionally engaging, addresses the main obstacle to low tea consumption in Indonesia. Thus, it contributes to the growth of the tea market and promotes healthier beverage choices among Indonesian consumers. The research results show that an aesthetic packaging design requires a sports cap type lid, a convex bottle body, a plain motif, and a square cross-section. Ergonomic packaging design requires a flip cap type lid, a wave-shaped bottle body, a textured motif, and a round cross-section. Simple packaging design requires a straw cap type lid, a serrated bottle body, a plain motif, and a square cross-section. This research aims to revitalize Indonesia's tea industry through consumer-oriented packaging design, increasing emotional and visual appeal. Key implications include increased consumer appeal, potential for increased consumption, better marketing strategies, and packaging design innovation that resonates emotionally with consumers.

Abstract

Identification of user needs and their conversion into product specifications is an important stage in the product design process. The large number of design methods currently available is a challenge for designers in choosing an effective and efficient design method. The aim of this literature review was to identify the use of product design methods between 2019-2023, mapped the effectiveness and efficiency of existing product design methods. Identification process used bibliometric analysis of articles in the SCOPUS database. VOSviewer software was used in the analysis process with co-occurence type and full-counting calculation methods. Effectiveness mapping was based on 7 criteria (E1 - E7) and efficiency based on 3 criteria (F1 - F3). The identification results show that the design methods that have been widely used in the last five years were value engineering, quality function deployment, user centered design, universal design, kansei engineering and TRIZ. The mapping results show that effective and efficient methods were QFD and value engineering. The effectiveness and efficiency of other methods were explained in more detail in this review.

Abstract

The establishment of the Kawasan Industri Terpadu Batang (KITB) opens up economic opportunities by absorbing labor and fulfilling needs based on local resources. Pekalongan City, which is adjacent to KITB, has the opportunity to gain financial and social benefits, reduce disparities in regional development, and increase Gross Regional Income (GRDP). However, Pekalongan City does not yet have a comprehensive map of resource potential that meets KITB's needs. This study aims to build a more comprehensive map of Pekalongan City's Resource potential according to KITB's needs. Descriptive qualitative analysis is used to analyze the multiplier effect of KITB and social mapping for mapping human resources according to KITB's needs. Meanwhile, quantitative analysis with shift-share and location quotient is used for its economic analysis. Finally, a SWOT analysis is carried out to describe the development strategy for local resource potential in Pekalongan City. The results of the study indicate that there are four (4) leading and potential sectors to be developed as drivers of the economy in Pekalongan City: (1) Accommodation and food and beverage provision; (2) Water supply; Waste, waste, and recycling management; (3) Construction; and (4) Health services and social activities. Based on the results of the multiplier impact analysis, there are 10 business sectors in Pekalongan City that are very closely related to the needs of KITB, such as the processing industry, creative industry, provision of accommodation and food and beverages, and others. 56.89% of the openly unemployed workforce in Pekalongan City have the opportunity to be absorbed as workers in various KITB industry tenants and with the skills they have and have been adjusted to the needs of 18 companies: sewing/garment skills, informatics, construction, and welding. In addition, several strategies were proposed by the Pekalongan City Government to develop the potential of local resources.

Abstract

Product design stages are important to consider critically in production. Generally, product design that shall be created by designer, should consider what the customer wants and needs. Nowadays issues, product design does not only consider the “wants and needs” of user, but also how the design can be created by embedding sustainability aspects in the product. Culture is also one of the important aspects which need to be considered in product design as culture affects the way users respond to the product. This paper aims to develop a new model for design development, in which the aspects of culture are incorporated into sustainable product design. By reviewing the existing literature, the authors attempt to identify the gaps of the existing papers, which illustrate how culture affects sustainable product design. Recent papers have only shown that culture influences product design, but they do not explore sustainability and the culture aspects in product design. Due to these gaps, it is therefore important to create a model which will assist designers to elicit sustainable product design based on cultural aspects. In summary, designers need to reflect on the “wants and needs” of users. The framework presented in this paper can be integrated into designers’ and companies’ decision-making during product design development. Keywords: Model, Culture, Sustainable, Product design, Product Development.
