Bandung City is one of the big cities in Indonesia that grappled with waste problem. There is 1,500 ton of waste produced daily, of which 65% is organic. In addition, the water content of the waste could reach 80% during rainy season, given that the waste is commonly collected in open space before transported to the final disposal area. In order to tackle this issue, the municipality of Bandung has started to implement anaerobic digesters to treat kitchen waste since 2013 in an attempt to reduce organic waste. There are three scales of bio-digesters that have been implemented: city 2 ton, communal (20-1000 kg) and household scale (20 kg), which comprise of 1 unit, 15 units and 100 units respectively. This study evaluate the efficiency and biogas productivity of each bio-digesters type. We analyzed 30 unit and 14 unit of household and communal biodigesters respectively. The waste input, slurry output and biogas production were estimated based on average of daily basis. Both the input and output of the biodigesters were characterized (TS, VS, COD) to gain further understanding. This study provide facts and figures to improve the further implementation of household bio-digesters in Bandung City.

<p>Microplastics are not only found in marine and lacustrine environments but also in soils. Microplastics enter natural soil environments from legal or illegal waste deposition. In arable soils, microplastics often stem from the decomposition of plastic sheeting. The accumulation of (micro-)plastic from garbage bags in which biological waste is often disposed, is also a significant problem for the recycling and composting of organic waste. Commercially available compostable bags are advertised as degradable. Thus, these compostable bags ought to accumulate less in soils than non-compostable bags. We present a pilot study to determine the preference of earthworms (Lumbricus terrestris and Eisenia hortensis) for taking up and translocating different types of microplastic in soils. Our initial findings from the soil column experiment suggest that the earthworms show a strong tendency for the uptake of microplastic.  We also observed direct and indirect transport of microplastic by earthworms from the surface to deeper parts of the soil columns.</p>

The aim of this paper is to identify patterns of waste management in the Bali archipelago tourism area. The Nusa Penida District is a new tourism destination located in the Southeast of Bali. In 2018, there were average 391,071 tourists/day coming and 45,520 local residents live in this area. The total amount of waste produced in Nusa Penida District is 15.90 tonnes/day or 173.61 m3/day. High tourist activities have not been handled by a good waste management. Questionnaires were distributed randomly to the public and tourists to find out the pattern of waste management. Observation also conducted to build the material flow analysis as a waste information baseline. Around 48.21% organic waste used as livestock feed and 8.45% dumped carelessly to the environment. Around 32.51% anorganic waste be burnt and 45.68% waste dumped carelessly. Moreover, Nusa Penida District facing offering waste management problem caused by their cultural activities. In total, around 8.82 tonnes/day waste is dumped in landfills and total unmanaged waste around 6.73 tonnes/day.

And Behavior

School institutions become producers of organic waste as a result of the daily consumption of school meals offered to students during the school year. An alternative, so that this material is not incorrectly released into the environment, is the implementation of a composting model that will reuse organic waste, generating humus, which will serve as fertilizer for the implementation of a vegetable garden in the school in the rural area. This work aims to propose a composter model in a School in the Rural Area of Manaus for the reuse of organic waste, to develop a prototype of composter for the production of humic substances and mineral nutrients for the creation of gardens, to prepare the manual with guidelines for the correct and sustainable management of the composting plant and the school garden and implementing the garden system through the composting process using school organic waste. The work is a case study that proposes to implement a prototype of compost for the production of humic substances and mineral nutrients for the construction of a school garden. It is intended that the proposal raises the awareness of the school community for the correct management and reuse of solid waste generated by the school and arouse in students and teachers the interest in environmental education and behavior change for the preservation of the environment in which they live.
