Waste Flow

Bali Province is an island of high tourist activity surrounded by the sea. Without a proper mainland waste management, waste problem will impact the aquatic environment. River and beach are waterways that become an important role in the waste flow that will end to the sea. Identification of waste in rivers and beaches is needed to determine the stream waste management policy. Measurements were made by adopting the NOAA (National Oceanic and Atmospheric Administration) method on 4 rivers and 4 beaches. Measurement of waste generation and composition represents the watershed and population density classification groups. The peak hour for the waste streams at 11.00-14.00 WITA (GMT+8). The dominant waste is organic waste (59.10% WW) and hazardous waste (17.12%WW). From the waste measurement on the beach, the waste density is around 0.087 tonnes/m3 and the composition of waste is dominated by plastic waste, paper waste, and textile waste. The average waste density in beach is around 0.007 kg/m2 or 0.53 items/m2. Yeh Gangga Beach is the dirtiest with 0.64 items waste/m2 and Lepang Beach is the cleanest beach with 0.27 items/m2.

Starting Point

The absence of accurate information on the state of waste is a challenge to the solid waste management system in Syria. The local authorities commonly estimate the quantity of waste produced and its characterisation, which is the starting point for solid waste management planning. So, this paper aims to evaluate the generation and composition of household solid waste in Homs city, Syria. Also, the study presents factors influencing the waste generation rate and the waste composition. The study was carried out in 300 families from four zones in Homs city, and three sampling stages were conducted during the study duration, which started in July 2017 and ended in February 2019. The outcomes show that an average of 0.68 kg/per/day solid waste generated was calculated for the entire study area in Homs city. Also, the data analysis presents that organic waste constitutes the largest component in the waste mixture (69.1%) followed by plastic (10.6%), inert materials (8.7%), paper (4.6%), textile (2.5%), metal (1.2%), glass (1.1%), wood (0.6%), and hazardous materials (1.6%). The multiple linear regression results showed that the adjusted R2 value was found to be 0.557, 0.839, and 0.709 for the waste generation per capita, the daily household organic waste generation, and the daily household packaging waste generation, respectively. Also, according to Pearson’s coefficient values, a positive correlation was found between household waste generation and monthly income (r = 0.626), household size (r = 0.37), and age of the household head (r = 0.517), whereas a negative correlation was found between household waste generation and the education level of the household head (r = −0.649).

Bhaktapur Municipality has been performing better to keep the city clean. However, scarcity of space for the land filling of the solid waste and proper segregation of waste at the source has been a hurdle for the Municipality. This paper aims to determine solid waste generation rate and to analyze overall situation of solid waste management of Bhaktapur Municipality. However, the data will not represent the seasonal and occasional variations. Additionally, waste from street-sweeping and large-scale institutional and commercial components of the Municipality has not been assessed. Arkin and Colton (1963) was referred for the sample size determination. Sample of 376 households were taken accordingly. Twenty representative samples each for commercial and institutional establishments were selected, and one each for special cases such as hospital, slaughter house and poultry has been assessed. Municipal household waste generation was found to be 0.093kg per capita per day which was chiefly composed of 77% organic, 18% plastic and 3% paper. Organic waste has been a major waste for institutions such as schools whereas at governmental and public offices, paper is the predominantly generated waste. Among commercial establishments, shops and restaurants mostly generate organic waste and that for departmental stores has been paper. Though collection system was found to be satisfactory, treatment and final disposal have been unsustainable. Available treatment facilities have been shut down whereas other infrastructural components have been lacking.

A complicated problem for big city governments today is the increasing volume of solid waste, due to population growth and mobility so that the waste load will also increase, especially in metropolitan cities such as Makassar City. To reduce the rate of organic waste generation, which is 60%, is to use organic waste as compost, both liquid and solid. The purpose of this study was to compare the effectiveness of composting with EM4 and MOL activators. The results of the study with the addition of EM4 activator, MOL activator and without the addition of activator from the first day to the fourteenth day the compost structure was different. The addition of MOL produces a slightly coarser structure compared to the addition of EM4, while the compost without activator still smells like wet waste. The quality (C/N) of compost, the addition of 100 ml of EM4 was in the optimum level, while the addition of 100 ml of MOL was less than optimum.

<p>Waste management in the Dasan Agung Market in Mataram City still uses conventional patterns. This pattern is not in line with the NTB Province policy that launched the concept of zero waste in 2019-2023. One approach that can support the program is the 3R method of waste management. This study aims to develop a waste management plan using the 3R approach. The method used in this study is the observation method, which is observing the current conditions and measuring the generation and composition of waste. The technique of determining the sample and measurement time and the procedure refers to SNI-19-3964-1995. The results showed that the amount of solid waste generation in Dasan Agung Market was 2.7 m<sup>3</sup> / day and the weight of solid waste was 467 kg / day. Waste composition was obtained by organic waste 52.60% and inorganic waste 47.40%. TPS 3R is planned with an area of 110 m<sup>2</sup>, namely 74 m<sup>2</sup> for composting area and 36 m<sup>2</sup> for sorting and handling inorganic waste, and residual waste. The composting system implemented is using the drum method with a capacity of 100 liters, a total of 307 pieces. Waste Management Planning using the 3R Approach is capable of handling 80% of the waste, and 20% of the residue is disposed of in the landfill.</p>

ITERA (Institut Teknologi Sumatera) is one of young university situated in Lampung Province, Indonesia. In 2018, the average population of campus (students, faculties, and staff) was about 9584 persons. The objective of this paper is to inventory Green House Gasses (GHGs) and then to calculate carbon footprint using equation by UI Greenmetric Guideline 2018 except for fuel and LPG consumption, paper use, and organic waste generation by using GHGs Protocol. Three scopes of GHGs emission were used to classify based on both direct and indirect source(s). The first scope was presented by LPG consumption and fuel consumption of campus’s car. Electricity consumption became scope 2 while the scope 3 involved paper use, organic waste generation including food waste and Yard trimmings, and transportation activities of both motorcycles and cars. The estimated GHGs emission was about 2846.541 metric ton CO2eq during 2018-2019 (one year) with the portion of each scope resulting 10.2%, 62%, and 28.2%, respectively. Electricity usage was being the highest contributor of carbon footprint. The inventory of GHGs will help top management of campus to evaluate and determine some strategies for minimization, reduction, and mitigation notably in electricity sector by some strategies such as substituting electric devices into eco-friendly products, applying energy management ISO 50001, and others.

<p>Masalah persampahan yang menumpuk dan belum terpilah di Kota Jakarta melatar belakangi penelitian ini. Salah satu penyebabnya adalah peningkatan jumlah penduduk yang berdampak kepada jumlah sampah yang terkumpul. Peningkatan tersebut tidak dibarengi oleh kepedulian masyarakat tentang pengelolaan sampah. Program Bank Sampah merupakan salah satu cara pengelolaan sampah yang dilaksanakan untuk mengurangi permasalahan tersebut. Tujuan dari studi ini adalah untuk mengevaluasi kinerja program Bank Sampah, mengetahui manfaat Bank Sampah dan potensi daur ulang sampah yang dihasilkan serta merencanakan pengembangan Bank Sampah di Kelurahan Rawajati. Metode yang digunakan untuk mengetahui timbulan dan komposisi sampah yaitu dengan SNI 19-3964-1994, Selain itu data penelitian diperoleh dengan melakukan pengamatan serta wawancara langsung di lapangan, selanjutnya dianalisis dengan deskriptif kuantitatif. Hasil penelitian memperlihatkan rata-rata laju timbulan sampah di Kelurahan Rawajati sebesar 0,3 kg/org/hari. Komposisi sampah di Kelurahan Rawajati paling tinggi adalah sampaah organik yaitu 76%, sedangkan sampah non organik 24% dimana yang paling tinggi adalah sampah lain-lain. Kelurahan Rawajati memiliki Bank Sampah yang sudah berjalan selama 5 tahun dengan jumlah nasabah sebanyak 17% dari total penduduk. Saat ini, Bank Sampah di Kelurahan Rawajati mampu mengurangi sampah non organik sebanyak 4,19%. Manfaat dari adanya Bank Sampah antara lain dalam bidang pengelolaan sampah, dalam segi ekonomi dan segi sosial. Potensi daur ulang sampah yang didapat sebanyak 9,69% dari 24% total sampah non organik. Untuk perencanaan 10 tahun kedepan yaitu pada tahun 2016-2025 Bank Sampah akan berkembang dengan penambahan jumlah nasabah, perluasan wilayah pelayanan dan penambahan jenis sampah yang diterima. Target yang ingin dicapai pada akhir tahun perencanaan adalah jumlah nasabah mencapai 80% dari total penduduk , sehingga mampu mengurangi sampah sebesar 20,11%. Selain penambahan jumlah nasabah, juga direncanakan untuk menambah jenis sampah seperti plastik PS, plastik kresek, kayu dan kain. Penambahan ini akan meningkatkan potensi daur ulang sampah dan memperbesar persentase pengurangan sampah.   </p><p>Keywords: waste management, non-organic waste, Waste generation, Waste Bank, Potential Recycling</p>

The position of composting household waste in terms of waste management at the macro level is very important, because household acts as a source of waste. When organic waste at household can be composted, then the waste transported to landfill will be reduced, so that the transportation costs of transporting waste involved is reduced, beside can extend the life of the landfill. To determine the effectiveness of household-scale composting process using aerobic composter, its potential in reducing household waste generation, as well as the quality of the resulting compost, we conducted this study. The results showed that: the composting process using "composter" aerobics can be run well and fairly effective, as well as describing the process of aerobic decomposition. It is heavily influenced by the composting process of assistance given to environment volunteers. Potential production of compost that can be generated by each family in one year as much as 43 kg, for families who have 1 (one) composter and 86 kg for a family that has 2 (two) composters. While the potential to reduce household waste generation by 21%, to which has 1 composter, and 42% to which has 2 composters. The compost production has good quality because it is free from microbial contaminants (pathogens), meet the requirements of mature compost and generally meet the parameters required by Permentan No 70 of 2011 or SNI compost of 2004. Keywords: composting, household waste, composter and reduction of waste generationAbstrakPosisi pengomposan sampah rumah tangga dalam kerangka pengelolaan sampah secara makro sangat penting, karena rumah tangga berperan sebagai sumber sampah. Apabila sampah organik di rumah tanggga dapat dikomposkan, maka sampah yang diangkut ke TPA menjadi berkurang, sehingga biaya transportasi pengangkutan sampah ikut berkurang, selain dapat memperpanjang umur TPA. Untuk mengetahui efektifitas proses komposting skala rumah tangga menggunakan komposter aerobik, potensinya dalam mereduksi timbulan sampah rumah tangga, serta kualitas kompos yang dihasilkan, maka dilakukanlah penelitian ini. Hasil penelitian menunjukkan bahwa: proses pengomposan menggunakan ”komposter” aerobik dapat berjalan dengan baik dan cukup efektif, serta menggambarkan proses dekomposisi secara aerobik. Hal tersebut sangat dipengaruhi oleh proses pendampingan pembuatan kompos yang tetap diberikan kepada kader lingkungan. Potensi produksi kompos yang dapat dihasilkan oleh masing-masing keluarga dalam 1 tahun sebanyak 43 kg, untuk keluarga yang memiliki 1 buah komposter dan 86 kg untuk keluarga yang memiliki 2 buah komposter. Sedangkan potensinya untuk mereduksi timbulan sampah rumah tangga sebesar 21%, untuk yang memiliki 1 komposter, dan 42% untuk yang memiliki 2 komposter. Produk kompos yang dihasilkan berkualitas baik karena bebas dari mikroba kontaminan (patogen),memenuhi persyaratan kompos matang dan secara umum memenuhi parameter-parameter yang dipersyaratkan oleh Permentan No. 70 Tahun 2011 atau SNI kompos Tahun 2004.Kata kunci: Komposting, sampah rumah tangga, komposter dan reduksi timbulan sampah

Waste Bank

Bank sampah di Kelurahan Palabuhanratu sudah berdiri sejak tahun 2010. Bank sampah ini adalah salah satu bank sampah diantara dua bank sampah lain, yang baru berdiri pada tahun  2016. Volume sampah pada tahun 2015 sebesar 134,89 m3 per hari, mencakup 89% wilayah Kelurahan Palabuhanratu ternyata masih belum optimal dalam pengolahannya, karena  sampah yang direduksi masih sekitar 5% dari total timbulan sampah yang dikirim ke TPA Cimenteng yang berlokasi sekitar 70 km dari Kelurahan Palabuhanratu. Kinerja bank sampah eksisting masih kurang, karena satu bank sampah hanya mampu melayani satu RW dan belum dapat melayani satu kelurahan. Selain itu, pengolahan sampah organik untuk dijadikan kompos belum dilakukan secara serentak oleh seluruh masyarakat, karena pengetahuan masyarakat yang masih kurang. Tujuan penelitian adalah mengetahui kondisi eksisting pengelolaan sampah dan merumuskan upaya revitalisasi Bank Sampah eksisting sebagai pihak pendukung pengelolaan sampah di TPS Kelurahan Palabuhanratu. Metode penelitian menggunakan metode survei, dengan menggunakan kuesioner, wawancara mendalam, dan observasi. Teknik analisis menggunakan analisis kuantitatif dan analisis kualitatif. Hasil penelitian menunjukkan bahwa masyarakat yang melakukan pemilahan sampah dari sumber hanya penduduk RT 01 RW 33. Selain itu jumlah TPS di Kelurahan Palabuhanratu masih terbatas, sehingga membutuhkan tambahan 5 unit TPS yang terintegrasi dengan bank sampah di kelurahan ini.Kata kunci: revitalisasi, bank sampah, PalabuhanratuThe  waste bank in Palabuhanratu Village  has been established since 2010. This waste bank is one of the waste bank among two other waste banks, newly established in 2016. The volume of waste in 2015 is 134,89 m3 per day, covering 89% of Palabuhanratu Village area  is still not optimal in its processing, because the reduced waste is still about 5% of the total waste generation delivered to the Cimenteng Final Diposal Site (FDS), which located about 70 km from Palabuhanratu Village. The existing waste bank’s performance is still very poor, because one waste bank can only serve one RW and can not serve the entire village. In addition, the processing of organic waste to be compost has not been done simultaneously by the whole community, due to the lack of people's knowledge. The purpose of this research is to know the existing condition of waste management and to formulate the revitalization of existing waste bank. The research used survey research method by using questionaire, in depth interview, and observation. Analytical technique using quantitative and qualitative analysis. The findings shows that the residents of Palabuhanratu Village who often do waste sorting from the source only from the residents of RT 01 RW 33. In addition, the number of existing temporary disposal site (TDS) in Palabuhanratu Village is still lacking, so it requires addition up to 5 units that integrated with waste bank in this village.Keywords: revitalization; waste bank, Palabuhanratu
