The Relationship Between Food Waste Management and Fly Density Level at Padang Restaurants in Tembalang District, Semarang City

It is necessary to observe and evaluate the performance of the authorized institutions, in particular, related to the sub-unit of the Environmental Agency, which manages the technical aspects (UPTD) and the five aspects of waste management to achieve better service to the people of Tembalang District. The UPTD is responsible for technical operations, including transporting domestic waste using arm roll and dump trucks, managing the cost budget plan, and supervising waste collection at waste collection site. Tembalang District has a minimum waste generation of 156 m3/day with a generation rate of 0.814 l/person/day and a maximum of 216 m3/day with a generation rate of 1.217 l/person/day. The implementation of the five management aspects in Tembalang District still needs to be evaluated from the operational, technical, and community participation aspects. This situation is related to the segregation and sorting of waste that has not been carried out, independent processing that has not gone well, and activities at the landfill that are not suitable. The community participation, public awareness, and concern for waste problems are still low where the independent waste management through waste treatment facility partnerships and waste banks are possible to do.

Background: Controlling of dengue vectors around dengue haemorrhagic fever cases is often conducted by using insecticides, including a malathion insecticide in the city of Semarang. A research on susceptibility status of Ae. aegypti to insecticides, used for fogging and based on a high number of hemorrhagic fever cases in Tembalang district, Semarang city, needs to be observed. Objective: This study aimed to determine resistance status of Ae. aegypti mosquitoes based on bioassay and biochemical tests of esterase non-specific enzyme activity in the Tembalang District. Methods: This study used a cross sectional design, it was conducted in June-September 2018 in a population of Aedes sp. from Tembalang District, Semarang City. Samples of F2 generations of female Ae. aegypti were obtained by ovitraps in the Tembalang District consisting of 12 urban villages, and their resistance status were tested by impregnated paper bioassay with malathion at a diagnostic dose of 0.8%. Esterase enzyme activity in the Ae. aegypti mosquito body of this population was tested biochemically to prove an increase in a non-specific esterase enzyme on the a-naphthyl acetate substrate. Results: The bioassay results showed that mortality rates of Ae. aegypti at the 12 villages in Tembalang district after 24 hourtest by impregnated paper indicated a range of 0-62%. Mechanism of resistance indicating an increase of non-specific enzyme esterase activity on a-naphthyl acetate at Rowosari, Kedungmundu, Sambiroto, and Meteseh could not be seen, It began to be seen in a low percentage (15%) at Sendang Mulyo, Tandang, Sendangguwo and Bubusan, and in a moderate percentage (45-75%) in Tembalang, Jangli and Mangunharjo. The mechanism of high esterase enzyme activity could be seen in the Ae. aegypti population at Kramas with AV=0,700-0,900 by a percentage of 20%, and AV=0,900 by a percentage of 80%. Conclusion: This study provided information about some Ae. aegypti mosquitoes from Tembalang District that showed resistance to the malathion insecticide with an elevation of non-specific esterase enzyme activity ona-naphthyl acetate substrate in several villages except Kelurahan Rowosari, Kedungmundu, Sambiroto, and Meteseh.

Waste is the remains of daily human activities and/or from natural processes in solid form, and the source of waste is the initial/first place where the waste is. Based on the chemical properties of waste it is grouped into two types, namely organic waste which consists of organic compounds (carbon, hydrogen, oxygen and nitrogen and are quickly decomposed/weathered) come from living/dead things. The second type is inorganic waste which consists of non-organic materials (difficult to be decomposed by soil microorganisms) so it is durable and does not decompose easily.

The management and prevention of food losses and waste in low- and middle-income countries: A mini-review in the Africa region.

Food waste management is an increasingly critical global issue, driven by the need to promote environmental sustainability, conserve resources, and mitigate global hunger. This study provides a theoretical analysis of the historical evolution of food waste management, examining its definition and international significance. Additionally, it critically evaluates the necessity of adopting sustainable approaches. The methodology involves a comprehensive literature review covering 2013 to 2023, utilizing keywords related to food waste, sustainability, and the circular economy. The databases consulted include Science Direct and MDPI. The findings indicate a shift from individual to institutional sources of food waste, highlighting the need for alternative management strategies. The environmental analysis underscores the negative impacts of conventional practices, while solutions such as food rescue, fermentation, and anaerobic digestion emerge as promising alternatives. Understanding consumer behavior is key, with smart labels introduced as potential tools to reduce food waste. The article also discusses the challenges and limitations of current food waste management practices, reinforcing the necessity of sustainable treatment methods. The study concludes by outlining future research directions, emphasizing the importance of understanding consumer behavior, investigating the potential of smart labels, and addressing existing knowledge gaps to foster a more sustainable and responsible approach to food consumption and waste management.

The COVID-19 pandemic disrupted global food waste patterns through unanticipated shifts in composition and quantities. This review explores the impacts of COVID-19 on food waste generation and management approaches in the Near East and North Africa (NENA) region during the recovery phase. This paper comprehensively explores food loss and waste in the NENA region. It presents a detailed analysis of pandemic-induced changes in household food waste behaviors, analyses the integration of circular economy principles in recovery strategies and policy implications, and outlines potential avenues for future research in this critical area. The key findings are threefold: First, this study reaffirms that food waste is a critical challenge in NENA, contributing to food insecurity, water scarcity, and environmental issues. Second, the pandemic catalyzed a dichotomy in consumer behaviors—panic buying initially increased waste, while hardship measures later encouraged sustainable waste reduction practices like meal planning and leftover use. Third, adopting a circular economy approach holds potential, yet its implementation remains limited in terms of curbing food waste and promoting sustainability in NENA. Overall, while the pandemic accentuated the urgency of tackling food waste, it also stimulated innovative policy thinking and strategic planning for building more resilient food systems. This paper concludes that leveraging pandemic-driven sustainability mindsets while addressing systemic drivers of waste will be key to mitigating food waste and its impacts moving forward. This paper offers timely insights into the evolving food waste management landscape in NENA, underscoring the need for integrated policies to navigate post-pandemic recovery effectively.

The existence of waste can have an impact on public health because it becomes a means and source of transmission of various disease agents. The indirect effect of waste on health can be due to vector-borne disease agents that multiply in the waste. Buried waste can be used by flies as a breeding ground. This study aims to analyze the relationship between waste management and the level of fly density at Kadompe Restaurants in Luwuk City. This was an analytic survey with a cross-sectional design, namely by analyzing the relationship between waste management and the level of fly density at Kadompe Restaurants. The study population was all Kadompe Restaurants located on Maahas Coast in Luwuk City, Central Sulawesi Province as many as 33 restaurants. The study samples involved 26 restaurants which were selected using purposive sampling based on certain consideration, namely restaurants that were still active. The instrument for measuring Fly Density was a fly grill by referring to the Regulation of the Minister of Health of the Republic of Indonesia No. 50 of 2017. Data on waste management included sorting, container, transportation that were collected by direct observation at the Food Stall based on the observation sheet provided in accordance with Law no. 18 of 2008 concerning Waste Management. Data were analyzed using chi-square test with α ≤ 0.05. The results of the study statistically showed the values regarding waste sorting (p=0.382; RP= 1.071; 95% CI=0.936-1.227), waste container (p=0.713; RP=1.045; 95% CI=0.958-1.141), and waste transportation (p=0.234; RP=0.909; 95% CI=0.754-1.096). Based on the results of the study, it can be concluded that there was no relationship between waste sorting, container and transportation with the level of fly density at Kadompe Restaurants in Luwuk City. The Agency for the Environment (DLH) should be able to transport waste every day from Kadompe Restaurants located on Maahas coast in Luwuk City.

Over recent years, the problem of food waste has been faced all around the world. Various reasons contribute to this, most of which are highly avoidable in nature. Ideally, it is the responsibility of every individual/institution to make every effort possible towards preventing food waste, but this study focussed only on the role of higher educational institutions. The overall aim of this project was to assess the practicalities of developing and implementing a food and packaging waste prevention programme in a university setting using the University of Salford, Manchester Metropolitan University, University of Manchester, Newcastle University and Small World Cafe (Oxford Road, Manchester) foodservices as case studies. The research involved carrying out face-to-face semi-structured interviews with the cooks, chefs, cafeteria managers and estate managers from all the participating institutions to collect qualitative data on the factors associated with food waste and the current food waste management practices at their facilities. The responses were thoroughly analysed to highlight the good practises and areas for improvement with regards to their food waste prevention and management practises. These findings included best practices and ideas for preventing pre- and post-consumer food waste along with suitable options for managing food waste in a university setting. These findings were then used to recommend a food waste prevention and management program.KeywordsUOS: University of SalfordMMU: Manchester metropolitan universityUOM: University Of ManchesterNU: Newcastle UniversitySWC: Small world cafe
