e-Waste is generated at the staggering rate of 6.1 kg per person. In 2016, 44.7 million tonnes was generated globally, and the amount is estimated to reach 52 million tonnes annually by 2021. The management of this huge quantity of e-waste is a major problem across the world, primarily in developing countries. An effective e-waste management system is linked to the sustainability of e-waste processing plants, and currently it is plagued with different supply chain network (SCN) issues. To address the issues and challenges of SCN, there is a need to prioritize and address the constructs. The study thus combines two multiple criteria decision making (MCDM) tools, the analytical hierarchy process (AHP) and quality function deployment, to prioritize the constructs identified from literature and supported by field studies. The house of quality (HOQ) has been used for analyzing different stakeholders’ requirements. The degree of importance for HOQ-1 has been derived using the AHP tool. The study revealed the most intriguing issues and challenges of e-waste processing plants considering the requirements of different stakeholders. The results showed formal collection, storage, semi-informal collection, and e-waste quality to be the major issues of processing plants. The findings obtained from MCDM analysis have been validated though two case studies in India and China. If the results obtained are applied to the existing e-waste SCN, a holistic e-waste management system can be achieved for developing countries.

AbstrakBerbagai macam upaya dilakukan oleh pemerintah untuk menciptakan lingkungan suatu kota yang bersih, diantaranya melalui penyediaan fasilitas sistem pemrosesan sampah sebagai tahapan akhir dalam pengelolaan sampah. Saat ini, Kabupaten Klungkung, Provinsi Bali memiliki 3 alternatif sistem pemrosesan sampah yang dapat diaplikasikan, yaitu: menggunakan tempat pemrosesan akhir sampah (TPA) eksisting Regional Bangli, membangun TPA baru tersendiri untuk Klungkung, dan pemrosesan akhir di Tempat Olah Sampah Setempat (TOSS). Penelitian ini bertujuan untuk memilih sistem pemrosesan sampah yang paling optimal dengan mempertimbangkan 4 kriteria, yaitu lingkungan, ekonomi, sosial dan teknis (analisis multikriteria) dengan menggunakan pendekatan Analytical Hierarchy Process (AHP). Setiap kriteria memiliki beberapa sub kriteria yang dimintakan kepada 35 orang responden yang mewakili 5 institusi pemerintahan daerah terkait untuk dilakukan penilaian perbandingan berpasangan. Penilaian juga dilakukan untuk mengevaluasi setiap alternatif terhadap semua sub kriteria dan kriteria. Secara global, responden lebih memilih pencegahan pencemaran lingkungan (nilai bobot 0,16) sebagai sub kriteria terpenting dari total 13 sub kriteria yang tersedia. Urutan kriteria yang dianggap lebih penting adalah lingkungan (nilai bobot 0,543), sosial (0,181), ekonomi (0,146) dan teknis (0,130). Untuk alternatif pengolahan sampah di fasilitas TOSS dianggap yang paling optimal (total nilai 0,47) disusul TPA Regional Bangli (0,28), terakhir TPA baru (0,25). Suatu alternatif sistem pemrosesan sampah dengan kelebihan dan kekurangan masing-masing harus dipilih yang paling dapat diterima oleh berbagai stakeholder terkait sehingga diharapkan dapat menjadi bagian dari suatu sistem pengelolaan sampah yang berkelanjutan dari suatu kota.AbstractIn order to create a city clean, efforts are taken by government including provision of waste processing system facility as part of waste management system. Recently, Klungkung Regency, Bali Province has 3 alternatives of waste processing system to be applied, namely: utilizing the existing regional final disposal site (TPA) of Bangli, building a new TPA facility dedicated for Klungkung area only, and on-site waste processing facility (TOSS). The study aims to determine the most optimal of waste processing system by considering 4 criteria, namely environment, economic, social and technical (multicriteria analysis) with the help of Analytical Hierarchy Process (AHP). Each criterion having several sub criterions were assessed by 35 respondents representing 5 local government’s institutions by applying pair wise comparison. The asessement were also performed to evaluate the alternatives to the given criteria and sub criterion. In global, respondents preferred to put environmental pollution prevention (weight of 0.16) as the most important among total 13 sub criterions available. Among the criteria, environment (weight of 0.543) was more prioritized than social (0.181), economic (0.146) and technical (0.130) aspects. Other result showed that TOSS (total value of 0.47) was more preferred than existing TPA of Bangli (0.28), and new TPA of Klungkung (0.25). An alternative of waste processing with its advantages and disadvantages should be chosen and acceptable by the related stakeholders, thus the facility becomes part of sustainable waste management system in a city.

The issue of waste management is still a thorny problem for Indonesia. This is because most of the waste produced by households still ends up in the Final Disposal Site (TPA). Meanwhile, the capacity of landfills, especially in big cities, is getting full. In fact, it is not easy to find land to open a new TPA to accommodate the garbage collected from the community. The purpose of this community service is to teach the residents of Kepuh Village to process household dry waste. The qualitative method used in this activity uses socialization and guidance. The stages in data analysis using qualitative methods are data reduction, data presentation, and drawing conclusions. The results of the discussion in this community service are [1] Implementation of Waste Bank Socialization at the Chairman's House [2] Dry waste collection [3] Waste sorting at Residents' Houses and [4] Implementation of waste bank at Village Hall. The conclusion is that people do not understand the effect of dry waste disposal on the environment, fostering independence with dry waste processing practices.

<p><em>The Design of Waste Managament Center in Surakarta with Ecological Architecture Approach is based on 3 things. First, waste problems in Indonesia need more solutions than just bin the waste, but the waste needs to be disposed properly. Second, Surakarta’s landfills is already overloaded because of the increase of waste produced. Third, there is the urge to applied ecological architecture to create a harmonious atmosphere between human and environment. This Waste Management Center designed to accomodate waste processing activity and with another supportive activities as a public facility. The method to design is problem solving by  reviewing ecological theories and applied it to the architectural component (space, site, mass and facade, structure and utility). Ecological architecture approach is applied to create a holistic design that enrich the quality of the environment and the lives of those who use them. Also, it is applied to create a harmonous atmosphere that could change society’s paradigm that waste management facility is not a disgusting dirty place but it is a clean, comfortable and eco-friendly living place to visit that leads to stimulate the visitor to not just bin the waste but dispose the waste properly.</em></p>

Municipal waste landfilling is the most common practice of municipal waste disposal in the Czech Republic. As a member state of the EU the Czech Republic must comply with the legislative requirements set for waste management. EU Council Directive 1999/31/EC requires member states to limit the amount of bio-degradable waste into landfill.To achieve the objectives of the Plan of Waste Management of the Czech Republic, various methods has been proposed. Prior to the waste processing, it is necessary to know the waste material composition, and after that select the most appropriate method and procedure for waste utilization or disposal.Therefore an analysis of graveyard waste composition has been carried out, where, by repeated measurements of samples weighing more than 500 kg (the total amount of analyzed waste was 3107 kg), it was found out that the graveyard waste consists of almost 77 % of bio-degradable matter. It is operationally impossible to separate bio-degradable matter from non-bio-degradable materials. Therefore it is desirable to collect compostable cemetery green waste separately from the waste coming from the decoration of gravestones that may be energetically utilized.

The Village

The Caga Traditional Village, which is located in Pejeng Kangin Village, Tampak Siring District, is one of the traditional villages that is currently seriously developing the village's potential as a tourist village. One of the efforts to improve that is now being promoted is regarding the cleanliness of the village. However, currently there is no comprehensive system capable of managing most of the waste generated by villagers. This village already has a waste bank but it only manages around 30% of the total waste generated. Organic waste which is much larger in quantity is still dumped in the "teba" or backyard. Another problem is the presence of residual waste, which has so far been collected and then transported to a landfill (TPS). The problem raised in this "community service program" is the public's ignorance of government policies regarding waste management and the proper procedures for managing waste from sources. Therefore, to support the government's efforts in realizing a waste management system from sources and to support the efforts of traditional villages to develop their potential as a tourism village, education on waste management from sources in the traditional village of Caga, Pejeng Kangin was implemented. Activities that have been carried out include the socialization of government regulations regarding waste processing at the source, optimization of waste banks, and processing of organic waste using the composting method. The implementation of Waste Processing from the Source by the Traditional Village of Caga, Tampaksiring District, Gianyar " received a good reception from the community and full support from the management of the Caga Traditional Village.
