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

Kecamatan Bulak merupakan perkampungan nelayan di Surabaya yang padat penduduk dengan kondisi sanitasinya kurang begitu baik. Sejak tahun 2017, ITS bekerjasama dengan National Taiwan University of Science and Technology (NTUST) membantu penyediaan sanitasi. Permasalahan yang terjadi di Bulak saat ini adalah penumpukan kulit kerang dan limbah pengasapan ikan yang belum dikelola. Kerang memiliki kandungan fosfat dan mineral yang bermanfaat untuk nutrisi, demikian juga pada limbah pengasapan ikan, sehingga dari limbah tersebut masih dapat dimanfaatkan menjadi produk pakan/pellet ikan yang memiliki kandungan nutrisi tinggi dan bernilai ekonomi. Pada tahun 2018 nelayan telah memiliki peralatan mesin pencacah kerang tetapi mesin tersebut sudah lama rusak dan tidak dipergunakan sehingga kegiatan pengabdian masyarakat yang dilakukan adalah memperbaiki mesin pembuat pellet dan melakukan pelatihan cara pembuatan pellet skala rumah tangga. Tahapan pertama dilakukan perbaikan mata potong mesin dan saringan, selanjutnya dilakukan dilakukan uji coba untuk pembuatan pelet ikan. Pelet yang telah dibuat dilakukan uji ukuran tepung ikan, karakteristik fisik, organoletptik, daya apung dan proksimat. Hasil uji proksimat pada tepung ikan didapatkan kadar air 5,72; abu 33,15; lemak 18,11; protein 33,26 dan karbohidrat 9,76%, sedangkan pada pellet menujukkan hasil uji fisik berwarna coklat dengan tekstur agak kasar dan beraroma. Hasil uji proksimat pada pellet menunjukkan kadar air 8,78; abu 23,48; lemak 11,02; protein 27,26 dan karbohidrat 29.46%. Warna pelet coklat muda, tekstur agak kasar, aroma khas dedak dan daya apung selama 50 detik. Hasil pelatihan pada masyarakat juga mendapatkan respon yang bagus bahkan bersemangat untuk membuat home industry produk pellet

Abstract

One of the innovations in utilizing plastic waste is to process it into Plastic Blocks for Wall Pairs (BPBPD). This research aimed to analyze the temperature required in melting used plastic and cooking oil for making BPBPD mixtures. Variations in the research are temperature under the range 180°C, 200°C, and 220°C. Comparison of the proportions of the mixture of plastic, oil, and coarse aggregate 5-10 mm, namely 1.5:1:0.5, 1:1:0.5, and 1:1:0.25. The types of plastic used are plastic bags, aluminum-coated plastic, and mica plastic. The parameters in this study are the compressive strength value, the initial rate of suction (IRS) value, the porosity value, and the water absorption rate. The study results showed that the minimum temperature for melting plastic bags and aluminum is 180°C, and for melting mica plastic is 220°C. The recommended proportion for making this BPBPD is a ratio of 1.5:1:0.5. The results of the IRS test on the plastic bags BPBPD ranged from 0.037-0.057 Kg/m2, the aluminum plastic BPBPD 0.030-0.057 Kg/m2, and the mica plastic BPBPD 0.033-0.043 Kg/m2. The water absorption rate for plastic BPBPD ranges from 0.233-0.378%, aluminum plastic BPBPD 1.644-4.233%, and mica plastic BPBPD 1.233-2.756%. Porosity results from the plastic bag BPBPD ranged from 0.355-0.931%, the aluminum plastic BPBPD 10.83-12.1%, and the mica plastic BPBPD 2.25-3.9%. In general, the compressive strength of BPBPD plastic bags, both without and with immersion, meets the minimum average compressive strength according to BSN 1989 with quality IV with the highest value in the 1.5:1:0.5 mixture of 38.2 Kg/cm2.
