The research to a circular economy requires reducing waste because it has urgency for the implementation of the Sustainable Development Goals (SDGs). One sector that has a high potential in implementing a circular economy in Indonesia is the textile industry. The synthetic textile industry has a large number of residual or waste materials that are harmful to humans and the environment. On the one hand, the natural dye textile industry uses main materials from plants that are environmentally friendly. In fact, the natural dye industry still produces waste both during plant cultivation and process fermentation of natural dye plants. This paper explores the circular economy potential in the natural dye textile industry of tarum (Indigofera tinctoria) from on farm to off farm. This data presents data collected through a survey, observation, and interview technique. These were analyzed using descriptive methods with observation techniques and literature studies. Results show that a circular economy concept has a potential in implementing sustainable concepts to farmers, industry, producers, and consumers so they can produce zero waste and reuse the natural dye industry by-products in order to support SDGs.
Disposable masks are widely used during the pandemic and post-pandemic as selfprotection from COVID-19. Due to this, a mask waste disposal problem has happened throughout the world, impacting the environment through pollution. Disposable waste management using the Willingness to Pay (WTP) system can be a mitigation effort. The study was conducted using an online cross-sectional questionnaire which was analyzed using the Spearman method and the SPSS cross tab descriptive analysis technique. The results of the study found that there is a positive correlation in the community's approval for the management of mask waste with the WTP response, which had a negative impact on the environment. However, it is negatively correlated with the amount of budget issued by the community with WTP. A SWOT (Strength, Weakness, Opportunity, Threat) study was proposed to evaluate the proposed WTP of the waste management system, finding that it is important to educate the public about the negative impacts. Therefore, WTP can be applied in the management of mask waste because it has advantages in waste management on a small to large scale.
Food security is a major concern in many countries, including Indonesia. Land productivity has decreased due to shrinking agricultural land, global warming, and land degradation. Precision agriculture (PA) empowers people to use agricultural technology to increase productivity. Therefore, this study aims to examine PA from adopting agricultural machinery. The method used in time series analysis is pooled least squares (PLS). The results show that the transition from conventional methods to using mechanized tools, especially tractors, significantly (at a sig level of 1%) affects rice production in Indonesian rice centers. These results form the basis that Indonesian rice farmers are enthusiastic about various technologies, so the opportunities for PA are significant. However, the gap between PA research in Indonesia and developed countries needs attention, and research collaboration can be a solution. From a practical standpoint, PA integrated with the internet is challenging for Indonesian farmers. Therefore, empowering farmers through various synergy mechanisms is proposed in this study.
Household waste management is still a problem that has not been fully solved in various countries, regions, and even in households, due to various factors from within and outside the individual. Nevertheless, efforts to improve waste management continue, including the Willingness to Pay (WTP) model for better waste management. The research hypothesizes that various important factors that influence WTP can lead to a circular economy. The research data is collected through an online survey with a total of 255 respondents, which overall discusses waste and the strategies in its management. Based on factor analysis, the area of residence (rural or urban areas) and the income of respondents have a significant effect on WTP decisions. Furthermore, the WTP decision is tested through respondents’ perceptions of various aspects of the circular economy that have an impact on health, awareness, desire, ability, and marketing prospects of waste which, when tested using the Spearman correlation, shows correlation between all aspects. We recommend these results to stakeholders to improve the management system of household waste management in both rural and urban areas through the WTP system, to achieve a circular economy.
Pandemi COVID-19 memberikan dampak luar biasa utamanya aspek kesehatan. Dalam rangka menjaga kesehatan, masyarakat selalu memperhatikan gaya hidup termasuk pada konsumsi. Peningkatan konsumsi sayuran berbanding lurus dengan tuntutan kesehatan masyarakat di masa pandemi. Namun, pengetahuan mengenai cara penyimpanan sayuran di masyarakat belum sepenuhnya merata. Salah satu penanganan pasca panen sayuran yang tepat dengan memanfaatkan teknologi yakni menggunakan lemari pendingin. Penelitian menggunakan jenis sayur bayam cabut (sayur daun) dan terung (sayur buah). Penelitian bertujuan untuk mendapatkan perlakuan terbaik dalam menyimpan sayuran daun dan sayuran buah serta menentukan strategi sosialisasi penanganan pasca panen kepada masyarakat. Penelitian dilaksanakan di Jebres, Surakarta. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 2 faktor yakni suhu penyimpanan (suhu ruang dan rendah) serta kemasan plastik PP (kemasan dan tanpa kemasan) dan 7 kali ulangan. Data hasil penelitian dianalisis dengan menggunakan metode deskriptif dengan teknik observasi dan studi literatur. Hasil penelitian menunjukkan bahwa baik sayur daun dan sayur buah memiliki umur simpan lebih lama pada penyimpanan di suhu rendah menggunakan kemasan. Kemudian diperlukan strategi sosialisasi penanganan pasca panen yang tepat agar meningkatkan pengetahuan masyarakat untuk mempertahankan umur simpan sayuran ditengah pandemic COVID-19.
