Abstract

Currently, environmental issues are a widely discussed topic in the industrial world, particularly within the supply chain process. This is closely linked to the escalating environmental degradation resulting from industrial activities. Today, a healthy environment is considered an invaluable asset, and the responsibility for its preservation lies with all of us [1]. Green supply chain management (GSCM) is an approach adopted by companies to integrate environmentally friendly practices into their supply chains [2]. GSCM aims to mitigate the negative environmental impact of business operations while maintaining operational efficiency and sustainability. One crucial aspect of GSCM is the adoption of green packaging. Green packaging not only involves using environmentally friendly materials but also entails raising awareness about the necessity for a shift in packaging practices (Prakash and Pathak, 2017). This study aims to systematically review the existing literature on green packaging. The primary focus of this research is to identify trends, findings, challenges, and the latest innovations in environmentally friendly packaging and to analyze their sustainability implications.

Abstract

Biodegradable film is a type of plastic that can be degraded easily by environmental microorganisms because it is made from natural polymer materials. In this study, experiments were conducted using papaya peel and noni fruit extract. Papaya fruit is utilized because the high production of papaya fruit leads to high papaya peel waste, which is currently not optimally utilized. Meanwhile, noni fruit is utilized as an antibacterial agent for biodegradable film because it contains anthraquinone, alkaloid, flavonoid, acubin, and alizarin. biodegradable film is expected to be an alternative packaging that can protect food ingredients from bacteria and become environmentally friendly packaging. The purpose of this study is to determine the effectiveness of noni fruit extract on antibacterial activity in biodegradable films and to find the right formulation for making biodegradable films from papaya skin added with noni fruit extract. The tests conducted in this study were mechanical test, solubility test, thickness, and water content, visual quality test, antibacterial activity test, and biodegradation test. biodegradable film showed varying tensile strength and elongation test results. The addition of noni extract was also effective in inhibiting bacterial growth. In addition, the samples showed significant absorbency and weight loss in the biodegradation test, signaling the potential to degrade.

Abstract

Indonesia is the world's largest palm oil producer, contributing 59% of the total global production. The decreasing availability of fossil fuels contrasts with the increasing energy demand due to population growth. The development of bioethanol as an alternative energy source is expected to replace fossil fuels while contributing to environmental sustainability. Oil palm empty fruit bunches (OPEFB) are abundant industrial waste which is a potential raw material for bioethanol production. This study aims to analyze two different R5I3 cell treatments and fermentation time on bioethanol production from OPEFB and to determine the type of cell and fermentation time that produces the highest bioethanol content. The experiment was conducted using a Randomized Block Design with two factors: cell treatment types (free and immobilized cells) and fermentation time (24, 48, 72, and 96 hours). The results showed that cell treatment types significantly affected reducing sugar content, pH, total dissolved solids, and ethanol concentration. Fermentation time influenced reducing sugar content, total dissolved solids, and ethanol concentration but had no significant effect on pH. The treatment of immobilized R5I3 cells with a fermentation time of 72 hours produced bioethanol with the highest ethanol content of 1.02% (v/v).

Abstract

National food security is highly dependent on the sustainability of the agricultural sector, where commodities such as bird’s eye chili are very important. In Malang Regency, especially in Wiyurejo Village, the income of bird’s eye chili farmers is strongly influenced by changes in crop yields caused by various internal and external factors, including climate change, agricultural practices, and limited capital resources. Despite the expansion of chili cultivation, farmers' incomes often do not show a substantial increase. This study aims to identify and analyze the determining factors that affect the income of bird’s eye chili farmers in Wiyurejo Village, with an emphasis on land area, capital, and production output. The methodology used is quantitative descriptive, using a multiple linear regression approach, and involving 98 randomly selected participants. The results of the study indicate that although land area is positively correlated with income, the effect is not statistically significant. Capital does not have a substantial effect on income, while production output has a very beneficial effect. The coefficient of determination is 78.1%, indicating that increased production output is an important determining factor for farmers' income and thus contributes to national food security. Therefore, increasing production efficiency can be the key to improving farmers' welfare and supporting national food security

Abstract

Sustainable agriculture is one solution to address global challenges such as climate change and environmental degradation. A critical aspect of sustainable agriculture is managing organic waste, especially livestock waste, which is often overlooked despite its great potential as a resource. In Lempake, Samarinda, the livestock sector produces quite significant livestock waste, but the management of this waste is still limited. This study aims to optimize the processing of livestock waste into environmentally friendly organic fertilizer and explore the obstacles and solutions in processing this waste. The survey results show that livestock waste such as cow, goat, and poultry manure can be converted into quality organic fertilizer by composting and using additional materials such as straw, leaves, and decomposer microorganisms (EM4). The resulting organic fertilizer can increase soil fertility, improve soil structure, and reduce dependence on synthetic chemical fertilizers. The main obstacles are livestock farmers' lack of knowledge and skills, limited technology and infrastructure, and low environmental awareness. The proposed solutions include training for livestock farmers, provision of technology and infrastructure, and increasing environmental awareness. This research is expected to contribute to sustainable agriculture and ecological conservation and become a model for other regions. Keywords: Organic fertilizer, Livestock manure waste, Sustainable agriculture
