PELATIHAN PEMBUATAN PUPUK KOMPOS DARI SAMPAH ORGANIK SEBAGAI REINTERVENSI MASALAH SAMPAH DI DESA KALUKUBODO KABUPATEN TAKALAR

Waste management is still an environmental problem that requires serious attention from the government and the community. All human activities always produce waste, one of which is organic waste from household waste. One way to minimize the negative impact of domestic organic waste is to process the waste using the composting method through community-based waste management efforts. Training on making compost is carried out as an effort to minimize the impact of organic waste on the community. This activity aims to train the community to be able to process their organic waste. This activity was carried out by visiting the residents of Kalukubodo village who were on the beach on July 1, 2022. The training on making compost was carried out by demonstrating the procedures and steps for making compost in front of the villagers who were gathering. After the training was held, the enthusiasm of the residents to procure compost increased. This is evidenced by the manufacture and use of compost in one of the houses of residents who have attended this training. So that this training activity for making compost can be said to be successful

Local waste management successfully reduces coastal plastic pollution

•Continent-wide surveys assessed changes in local waste management •An average reduction in coastal litter of 29% over 6 years was observed •Encouraging stewardship of coastal areas reduces coastal plastic litter •Economic motives to discard waste correctly linked with less plastic Regardless of where plastic pollution originates, the management interventions made at the local level are crucial to the global success of reducing plastic pollution. Reduced plastic consumption and pollution have been observed in communities with plastic taxes and educational programs. However, there is currently a lack of a quantitative framework that connects local actions to measurable reductions of plastic loads in the nearby coastal environment. Here, we explore whether changes in municipal waste management efforts corresponded to decreases in coastal plastic pollution across the continent of Australia. Our research shows that local strategies can result in large-scale benefits. We observed an average reduction in coastal litter of 29% over 6 years at the continental scale. Strategies that encouraged stewardship of coastal areas and economically motivated appropriate waste disposal were correlated with reductions in plastic pollution. This work can guide the efforts of policymakers and citizens alike to reduce plastic pollution at local, national, and global scales.

Pengelolaan Limbah Industri Pengolahan Hasil Perikanan: Studi Kasus Pada Usaha Mikro Kecil dan Menengah (UMKM) Sambal Ikan Tuna Di Kabupaten Cilacap

One of the fisheries and marine potentials in Cilacap Regency is tuna fisheries. Catch tuna that landed at the Cilacap Ocean Fishery Port (PPSC) is high. Based on the analysis of the needs of actors in the tuna fisheries system in Cilacap, one of the components included in the system is the tuna fish processing industry. This is because there is only one tuna fishing company in Cilacap in 2009. The existence of these problems causes an increase in the growth of the micro-industry in the tuna fish processing business in Cilacap. This increase certainly has an impact on increasing the waste generated. This study aims to identify the type of waste generated and the waste management efforts of micro-industry players (MSMEs) processing tuna chili sauce in Cilacap and analyze the appropriate management design to be applied in the tuna fish sauce processing industry. The research data collection method was carried out by direct observation by conducting interviews with the owners of MSMEs. The results of field observations on MSMEs that produce tuna fish sauce produce organic and non-organic waste and the waste is simply thrown into the environment without any treatment first. Efforts to manage waste produced by MSMEs with tuna sauce have not yet been carried out due to limited human resources in knowledge about waste management. Based on the characteristics of the waste produced, several types of designs can be carried out by MSMEs, namely the management of organic and non-organic wastes to minimize the waste generated both in terms of quality and quantity as not to pollute the environment.

EVALUASI KEBIJAKAN TERHADAP PENGELOLAAN SAMPAH KAWASAN DAN TIMBULAN DI KOTA TANGERANG SELATAN

The discussion in our study is about evaluating regional waste management policies and generation in South Tangerang City. In this policy, there are still many obstacles in the field, either performance or inadequate facilities. The achievement of policy objectives has not been optimal due to related parties to external factors, people who are less aware of waste management and the impact of waste hazards. This study aims to investigate the implementation of regional waste management and generation in South Tangerang City. The policy evaluation was analyzed from various aspects, namely: a) Effectiveness, policy evaluation is one of the important stages in the policy cycle. Policy evaluation is carried out after the public policy is implemented. This is to test the policies that have been made are successful or not. b) Efficiency, this is to show the best comparison between an activity and its results. This efficiency is a measure of success that is assessed in terms of human resources and costs to achieve the results of the policies implemented. c) Accuracy, to measure the extent to which a level of effectiveness satisfies a need, value, or opportunity to create a problem. d) Equity is a policy that is created and implemented which is oriented towards equity, meaning that it is a policy that is equitably distributed. e) Responsiveness, this criterion relates to how far a policy can satisfy the needs, preferences, or values ​​of certain groups. This criterion is very important because the analysis can satisfy other criteria. f) Accuracy, this criterion is closely related to rationality and substantive. Because the accuracy of the policy is not related to an individual criterion but two or more together. The method used in this study is a descriptive method with a qualitative approach. Waste management has been regulated, but its implementation has not run optimally. Waste management efforts in South Tangerang City are not enough just to rely on the establishment of Waste Banks and the involvement of the community to participate in managing and also sorting out biodegradable and non-biodegradable waste. In addition, the downstream waste problem will not be solved if the upstream does not implement the existing regulations. The government must conduct socialization to the community to sort organic and inorganic waste from home, sort waste from the generation and source areas, Temporary Disposal Sites (TPS) and Final Disposal Sites (TPA).

Garbage Classification Using Ensemble DenseNet169

Garbage is a big problem for the sustainability of the environment, economy, and society, where the demand for waste increases along with the growth of society and its needs. Where in 2019 Indonesia was able to produce 66-67 million tons of waste, which is an increase from the previous year of 2 to 3 million tons of waste. Waste management efforts have been carried out by the government, including by making waste sorting regulations. This sorting is known as 3R (reduce, reuse, recycle), but most people do not sort their waste properly. In this study, a model was developed that can sort out 6 types of waste including: cardboard, glass, metal, paper, plastic, trash. The model was built using the transfer learning method with a pretrained model DenseNet169. Where the optimal results are shown for the classes that have been oversampling previously with an accuracy of 91%, an increase of 1% compared to the model that has an unbalanced data distribution. The next model optimization is done by applying the ensemble method to the four models that have been oversampled on the training dataset with the same architecture. This method shows an increase of 3% to 5% while the final accuracy on the test of dataset is 96%.

Food waste handling perception in Indonesia: communicating the sustainability of Food and environment

Every week, Indonesia discards approximately 10 million pieces of bread, cakes, and cookies, equating to 292,000 tons of CO2 emissions similar to Indonesia’s annual CO2 emissions. Due to a lack of resources and infrastructure, most impoverished countries rely on antiquated technologies such as anaerobic digestion (AD) to handle food waste. Bakery trash is a biologically formed organic waste that poses a serious threat to public health and the environment, including natural ecosystem contamination. The goal of this study is to find out how much effort Indonesians put into garbage management. How do they spread the word about leftovers through the media? How do they know about waste, particularly bread waste? As well as community-wide corrective steps to protect the environment from domestic food waste management. This study employs a quantitative approach. In order to send 100 questionnaires to persons in Indonesia, purposive sampling was used. Surveys are carried out using Google forms, which require a valid Google email address in order to ensure that each person only takes the survey once. The study’s conclusion is that food waste management efforts among Indonesians are hampered by the public’s lack of understanding of food waste management and disposal information in the media. The research sample understands the process of recycling food into pet food when it becomes garbage, according to their perceptions about the end process of food. In terms of food waste awareness, the majority of the participants in this study were aware that food waste is disposed of in landfills rather than being recycled.

Optimization of organic waste processing using Black Soldier Fly larvae Case study: Diponegoro university

Waste that is not handled correctly can cause problems for humans and the environment. Therefore, proper waste management efforts are needed to solve this waste problem. One method of processing organic waste is the use of Black Soldier Fly (BSF) larvae. Larvae BSF can degrade organic waste, and the life cycle of BSF acts as a decomposer. This study examines BSF larvae’s ability to decompose biodegradable organic waste, especially for banana waste, cucumber waste, and food waste in the Diponegoro University environment, and to decide the effect of the variable type of food. The frequency of feeding carried out on the growth rate of BSF larvae and to choose the decomposition results of biodegradable organic waste carried out by BSF larvae. This research method is carried out by comparing the effectiveness of waste degradation by BFS with EM4. The value of significance in degrading waste is obtained from the calculation of the Waste Reduction Index, or it can be called WRI. The analysis results show that the WRI value in waste processing using BFS is more significant than in waste processing using EM4. That concludes that BSF fly larvae (Hermetia illucens) effectively reduce organic waste compared to EM4.

Management and safety practices in utilization of agro-food waste among urban agro-producer households

BACKGROUND AND OBJECTIVES: Whereas management of waste in urban areas across the globe is essentially a public service, there is dearth of knowledge on waste management efforts at the household level in developing countries. The study aimed to avail crucial information on the largely informal management of agro-food waste that is practiced in low- and lower middle-income countries. Insights of safety measures adopted in the utilization of agro-food wasteamong urban agro-producers were explored empirically.METHODOLOGY: An electronically-structured questionnaire was administered on a sample of 456 urban agro-producer households for data collection.Descriptive as well asMultivariate Probit models were employed for analysis.FINDINGS: The results indicated significant disparities in management options and safety risk management practices between the participating and non-participating livestock and mixed producers. Waste reduction (86%), utilization (86%), segregation (63%) and composting (58%) were the most preferred waste management practices. Waste disposal (18%) and mixing with salt/dry feeds (24%) were lowly preferred methods. Whereas the regression models showed disparities in the contextual factors influencing management options and safety risk measures, the knowledge variables (waste sorting and urban agriculture knowledge) had greater influence across these agro-food waste aspects. This implies that implementation of education programs in agro-food waste management and safety risk management practices among urban agro-producer households by urban authorities would enhance sustainable food safety in urban food supply chains.CONCLUSION: The findings could inform self-management efforts of agro-food waste in small-urban agribusinesses thus increasing economic benefits and improving environmental wellbeing.

Determinants of Street Littering in an Urban Setting in South-South Nigeria

Littering is an inherent societal problem that has been marginalized in waste management efforts most especially in some low- and middle-income countries. Though its effect might seem negligible to the individual, its consequences on the environment remain substantial. The objective of this survey is to determine the socio-demographic and behavioural determinants of street littering among inhabitants in an urban Local Government Area (LGA) in Benin City. A descriptive cross-sectional study was carried out in Oredo LGA of Benin City amongst 422 respondents with an interviewer-administered structured questionnaire using a cluster sampling technique. Data were analysed using the SPSS version 16 statistical software. The mean age of respondents was 30.01 (±19.53) years. Respondents' most common method of litter disposal was either by putting them into waste bins (52.6%) or burning the trash (28.7%). Legislation (43.4%) and availability of street bins (40.5%) were the most effective measures identified to curb littering behaviour. There was a statistically significant association between street littering tendencies and age (p<0.001), gender (p<0.001) and educational status (p<0.009) of the respondents. In conclusion, age, gender and educational status of respondents were significantly associated with littering behaviour. Environmental policy review, improved health promotion activities and provision of anti-littering infrastructure is recommended.

Estimating construction waste generation in the Greater Bay Area, China using machine learning

Reliable construction waste generation data is a prerequisite for any evidence-based waste management effort, but such data remains scarce in many developing economies owing to their rudimentary recording systems. By referring to several models proposed for estimating waste generation, this study aims to develop a reliable and accessible method for estimating construction waste generation based on limited publicly available data. The study has two objectives. Firstly, it aims to estimate construction waste generation by focusing on the Greater Bay Area (GBA) in China, one of the world’s most thriving regions in terms of construction activities. Secondly, it aims to compare the strengths and weaknesses of various waste quantification models. 43 sets of annual socio-economic, construction-related and C&D waste generation data ranging from 2005 to 2019 were collected from the local government authorities. By analyzing the data using four types of machine learning models, namely multiple linear regression, decision tree, grey models, and artificial neural network, it is found that all calibrated models, with their respective strengths and weaknesses, can produce acceptable results with the testing R2 ranging from 0.756 to 0.977. This study also reveals that the 11 cities in the GBA produced a total of about 364 million m3 of construction waste in 2018. The result can be used for monitoring the urban metabolism, quantifying carbon emission, developing a circular economy, valorizing recycled materials, and strategic planning of waste management facilities in the GBA. The research findings also contribute to the methodologies for estimating waste generation using limited data.

Valuation of Ecobricks as an Artificial Resource in Hardscape Materials

The Medan City TPA in the Waterfall Village, Medan Marelan District is the final disposal site for the City of Medan. The composition of the waste at the Waterfall TPA in 2017 consisted of 71.5% organic; Paper 2%; Plastic 10.1%; wood 2%; fabric 2.5% rubber 2.5%; metal 0.6%; glass 0.8%; 1 % chunks; pampers / sanitary napkins 3, 1% and others 3.8% (Department of Hygiene and Parks City Medan). Based on this condition, if waste management efforts are not carried out properly, the service level based on the MDGs (Millineum Development Goals) target of 80% will not be achieved. The composition of plastic waste of 10.1% is quite high. The Ministry of Environment and Forestry (2017) stated that plastic waste increased by 15% from 10% in 2005. The increase will continue in line with the need and use of plastic. Plastic is difficult to decompose, so one thing that can be done is only with 3 R's, namely reuse, reduce and recycle. Reuse by using plastic over and over again, reduce by reducing the use of plastic and recycle by recycling plastic. one of the recycled plastics is with eco-bricks. Ecobricks are a collection of all types of used, clean and dry plastic in used plastic bottles so that they reach a certain density and function as building blocks that can be used over and over again. Ecobrick is a simple solution and simple technology in recycling plastic. Ecobricks can provide direct benefits of Rp. 289,000, - / m2 - Rp. 471.000, - / m2, the price of waste utilization is 57.800-78.500 gr/m2, the price of indirect utilization is Rp. 404,600 – Rp. 549,500 m2

Analisis Pelaksanaan Pengelolaan Sampah di Kabupaten Aceh Barat

The ratification of West Aceh District Regulation (Qanun) Number 4 of 2017 concerning waste management has become a guideline for the West Aceh District government to achieve solid waste management objectives. The regional regulation guarantees legal certainty, clarity of responsibility of the authority of the regional government, the participation of the community and the business sector / private sector so that waste management can run effectively and efficiently. The purpose of this study was to determine the implementation of Qanun Number 4 of 2017 Article 10 concerning waste management in West Aceh Regency in 2019. The method used in this study was to use a qualitative descriptive approach. Data collection techniques used are documentation and interviews. The informants in this study were 8 people. Data analysis was performed using qualitative data analysis techniques. The results showed that the implementation of Qanun Number 4 of 2017 Article 10 concerning waste management in West Aceh District Year 2019 in waste reduction was still not optimal, this was due to the lack of effort and management of the government in managing waste in the community environment such as lack of facilities and infrastructure in management garbage. There are still many piles of rubbish on the edges of the highway that make West Aceh District still look dirty and dirty. For the handling of waste carried out by the Office of Environment of West Aceh District Head is not optimal, this is because the lack of cleaners is also a major factor in the failure of waste management. There has been no firm action from the government on waste management efforts such as the implementation of West Aceh District Qanun Number 4 of 2017 Chapter XVII on Article 63 Criminal Provisions and lack of socialization from the government on waste management so that public awareness in managing waste is still reduced

Waste management efforts in North Sumatra are carried out in various ways, including through the Waste Bank program. Saving waste in the waste bank is carried out by buying and selling waste. The type of research used is empirical legal research. The practice of buying and selling waste at the Sunggal Mandiri Garbage Bank with residents, namely in the collection, management, and utilization of waste, where the community directly contributes to the collection and sorting of waste, while the Garbage Bank is tasked with managing waste so that waste can be disposed of. In article 4 paragraph 1 of the Consumer Protection Act No. 8 of 1999, consumers or property buyers have rights including comfort, security and safety in consuming products and services and choosing them according to the exchange rate and conditions according to the agreement.

THE PERFORMANCE EFFECTS OF SOLID WASTE FROM BAGASSE ON INCREASED OIL RECOVERY

Aims: This study aims to determine the synthesis of bagasse to form surfactants and evaluation of the performance of the sample to increase oil yield. Indonesia generates very large amounts of solid waste, without recycling or adequate management efforts to preserve the environment. Bagasse emerged as one of the most abundant biomass due to the operations of large plantations and factories. Furthermore, previous studies showed extensive uses in the fields of compost, animal feed, bioethanol energy, paper, and reinforced building materials. Methodology and Results: Lignin was extracted from bagasse to process sodium lignosulfonate surfactant (SLS surfactant). The synthesis was characterized several times, and certain examples showed significant HLB values, as a function of emulsion builder. This condition in the oil reservoir is required to reduce interface stress (IFT) and friction in the movement of particles. Another analyses involves the assessment of core flooding of specific synthetic core and crude samples. Conclusion, significance and impact of study: The results confirm the ability of surfactant bagasse to increase oil recovery, namely the HLB value of 11.6. The results also show the surfactant classification with the ability to form a middle-phase emulsion in order to increase petroleum products. Therefore, bagasse as solid waste has a performance effect on the process of increasing petroleum production.

Estimation of Domestic Waste Volume as A Sustainable Waste Management Efforts In Mataram City

In this research, the problem formulation is based on the central issues in sustainable domestic waste management. In domestic waste management, information is needed regarding the existing volume and the projected volume of domestic waste in the next ten years. This study's objectives are (1) to determine the volume of domestic waste in Mataram, (2) to project the volume of domestic waste in the next ten years in the city of Mataram. Based on the data analysis results, it is found that the generation of domestic waste in Mataram City in units of weight is 0.4 kg/person/day, while the amount of domestic waste generation in Mataram City in volume units is 0.0020 m 3 /day. The composition of domestic waste in Mataram City is dominated by wet organic waste at 64%, followed by dry organic waste, non-medical hazardous waste, and plastic packaging, which have the same percentage, namely 6%. The type of waste with the least amount is metal and hazardous medical waste, only 1%. The projected population growth for the City of Mataram has increased with an average growth per year of 1.99%. An increase followed this in the projected waste generation. In 2020 the population is 496,401 people with a waste generation of 1,005 m 3 /year. Meanwhile, in 2029 the total population of 583,571 people will generate 1,182 m 3 /year of waste.
