“…In Yaoundé, for example, strong seasonal variations and heavy rainfall affect both the production of MSW (between 30,000 and 50,000 tons per month) and the rate of its collection (only 43% of the MSW is collected by MSW services due to poor road conditions) (Parrot et al 2009a). Yaoundé produces large quantities of organic materials, and these account for approximately 78% of the MSW (Sotamenou et al et al 2019). In this city, two local nongovernmental organizations (NGOs), Tamtam Mobile and Gevolec, recycle part of these organic materials in the form of compost.…”

“…The involvement of researchers, firms, associations, NGOs, and public representatives would create an emerging market of organic materials that would be not only efficient but also safe for the users. Included in a global strategy for the management and recycling of organic materials, public incentives, for example, waste transfer stations equipped with containers located close to households, would improve the efficiency of collection of organic materials by private firms (Sotamenou et al 2019), provide employment Table 2 Fertilization value based on N/P 2 O 5 /K 2 O content and market price in local markets of the three most abundant types of organic material collected in Yaoundé and Bafoussam (fresh weight basis, US dollars, mean, Cameroon). All calculations are based on the equivalent of a 50-kg bag of organic material, 50 kg being the usual unit for chemical fertilizers.…”

The rapid expansion of cities in sub-Saharan Africa generates increasing volumes of diversified organic wastes that require management and a high population need for local and fresh vegetables. Linking the different sources of organic materials generated in these cities with the needs of local food producers for fertilizers prepared from recycled organic materials is challenging. This requires that producers obtain the results they expect from the organic materials they recycle. Thus, recycling these organic materials in their raw form or after composting presents an opportunity for periurban agriculture, although the great variability in the quantity and quality of these materials raises questions about the consistency between their agronomic value and their economic value. In two large cities of Cameroon (Yaoundé and Bafoussam), different types of organic materials were sampled: unprocessed livestock waste and composts from manure or municipal solid waste. From an agronomic perspective, we calculated the fertilization value based on the nutrient (nitrogen, phosphorus, and potassium) content of the organic materials. From an economic perspective, we calculated the value based on the nutrient content of the organic materials and their substitution unit prices and recorded the current market price. This is the first time that this combined approach has been used in sub-Saharan Africa. Our results showed considerable variability and discrepancy in both the agronomic and the economic values. The market prices overvalued the urban composts by a factor of 6, while chicken feces were undervalued by a factor of 3. The unprocessed organic materials were the most interesting from an economic and agronomic perspective. Our findings suggest that (i) the composting process needs to be improved and (ii) the humus potential should be calculated to better assess the amendment value of organic materials and as a basis for adjusting their market price.

“…First, to the best of our knowledge, it is the very first that addresses the aspect of household waste disposal from a gender perspective especially in Africa. A similar study for Ghana ( Adzawla et al., 2019 ; Alhassan et al., 2020 ) and Sotamenou et al. (2019) for Cameroon adopted a gender-blind analysis in their investigation.…”

Very crucial in this study rests on the observed and unobserved heterogeneity of household types.…”

“…Selain itu jarak tempuh menuju recycling agent juga menjadi faktor yang mempengaruhi secara langsung. Menurut [7] menjelaskan bahwa jarak penampungan sampah mempengaruhi seseorang untuk membuang sampah, semakin dekat jarak tempat pengolahan sampah maka akan semakin tinggi kemungkinan seseorang melakukan perilaku pengolahan sampah. Selain itu, outcome (keuntungan finansial) dari penjualan sampah merupakan faktor yang signifikan mempengaruhi behavior seseorang dalam partisipasi kegiatan bank sampah [5].…”

Abstrak - Pemerintah Kota Semarang melakukan pembentukan bank sampah untuk menekan jumlah sampah di tempat pembuangan akhir. Masih bayak masyarakat di Kota Semarang yang belum mengikuti program tersebut. Pada penelitian ini dilakukan pemodelan untuk meningkatkan partisipasi masyarakat dalam mengelola sampah. Keikutsertaan masyarakat dipengaruhi oleh beberapa faktor yaitu intention, sosial norm, jarak menuju recyclingsiteagent dan outcome. Intention seseorang dalam melakukan pengelolaan sampah secara signifikan dipengaruhi oleh awareness of consequences, ascription of responsibility dan personal norm. Pemodelan dan skenario menggunakan metode agent based modeling, menghasilkan usulan kebijakan yaitu dengan mendirikan empat bank sampah. Melalui keputusan tersebut mampu menghasilkan 93% partisipasi rumah tangga dalam mengelola sampah dan 2,4 ton sampah yang dikumpulkan hingga periode ke 60 minggu.Abstract - Semarang government has established a Waste Bank to reduce the amount of waste in landfills. There are still many people in Semarang who have not participated in this program. This research modeling aims to increase public participation in managing waste. Public participation is influenced by intention, social norm, and distance to recycling site agents as well as the outcome. An intention to of managing waste is significantly influenced by awareness of consequences, the ascription of responsibility and personal norm. In this study using agent-based modeling. The results obtained from this model and scenarios are the intervention to establishing four Waste Bank. It produced 93% of households participating in managing waste and 2.4 tons of garbage collected in the 60 weeks.Keywords – Agent-based modeling, Norm Activation Model, Waste Separation Behavior, Bank Sampah,
