Abstract

Bojonegoro market is a type A traditional market where there is high trading activity in Bojonegoro. Buying and selling activities at the Bojonegoro market cause leftovers to be generated every day. The remaining activities in the form of solids or what is called waste will affect the generation that occurs. The purpose of this study is to determine the generation data, density and composition of Bojonegoro Market waste. The method used is descriptive quantitative by calculating waste generation. Garbage measurement and sampling activities were carried out for eight consecutive days in accordance with SNI 19-3964-1994 reference. The results showed that the Bojonegoro market waste generation was 146 kg/day with a density value of 210 kg/m3. The composition of the top three is dominated by coconut shell waste of 78.3 kg/day, vegetable waste of 11.2 kg/day, and fruit waste of 8.4 kg/day.

Abstract

Solid waste generation can increase due to people's activities that increase compared to the early pandemic in 2020. The solid waste management paradigm is no longer focused on landfilling waste in landfills. Solid waste reduction activities can extend the landfill's lifetime, one of the reduction activity facilities is Material Recovery Facilities (MRF). Surabaya, the capital city of East Java Province in Indonesia, has several MRF. One of them is Tambak Osowilangon . This study aims to determine the solid waste reduction in ponds in Osowilangon Material Recovery Facility during the COVID-19 pandemic and to predict greenhouse gas reduction based on solid waste. The triangular method calculates the greenhouse gases (GHG) prediction of solid waste management in Osowilangon MRF. Solid waste generation in Tambak Osowilangon MRF was produced at 2704.946 kg/day. The highest composition of solid waste was achieved by food waste (63%), and the existing reduction of solid waste in Ponds Osowilangon MRF is 56.08%. The total volume of GHG produced without reduction scenario is 6.16 x 10 6 m 3 /year, while the GHG produced from an existing reduction in Tambakosowilangon MRF is 2.4 x 10 6 m 3/ year. Solid waste management in Tambakosowilangon MRF can reduce 61.04% of the total GHG volume

Abstract

Terminal Purabaya merupakan terminal terbesar di Jawa Timur. Aktivitas bus di dalam terminal berpotensi pada peningkatan emisi gas rumah kaca (GRK). Penelitian ini menganalisis emisi gas rumah kaca dari aktivitas bus pada saat diam (kondisi idle) namun dengan kondisi mesin menyala di Terminal Purabaya. Emisi tersebut dari konsumsi bahan bakar pada saat mesin bus menyala. Parameter udara gas rumah kaca pada penelitian ini adalah gas CO2, CH4, dan N2O. Aktivitas bus yang diteliti adalah bus Antar Kota Antar Provinsi dan Dalam Provinsi (AKAP-AKDP) serta bus kota. Pengambilan data primer berupa waktu tunggu bus AKAP-AKDP dan bus kota ketika menunggu penumpang pada Bulan Mei 2019. Pengamatan waktu tunggu bus tersebut dilakukan pada jam 06.00-10.00 dan 16.00-20.00. Hasil perhitungan emisi GRK menunjukkan emisi CO2eq bus AKAP-AKDP pada saat kondisi idle sebesar 1.147,92 ton/tahun dan bus kota sebesar 831,63 ton/tahun.

Abstract

People’s growth and their activities increase waste generation. Therefore, efforts to reduce waste are needed, including community-based reduction efforts. This research is located in Gading and Dukuh Setro sub-districts in Surabaya City. The purpose of this study was to measure the potential for waste reduction and greenhouse gas reduction. Measurement of waste generation, waste composition, and waste density was based on SNI 19-3964-1994. The researcher conducted sampling in low, middle, and high-income areas, covering 83 families. Greenhouse gas emissions were estimated using the LandGEM (U.S. EPA) method based on the waste disposed at landfill, considering the existing reduction conditions and optimal material recovery. Solid waste generation in 2022 per year was 4.695,58 tons. The largest composition of waste consisted of biodegradable waste (37.13%), plastic waste (25.73%), and diapers and sanitary napkins (18.25%). The average density of loose waste was 152.42 kg/m3. The existing reduction had 1.47% waste bank reduction activity and 0.72% composting reduction activity, for a total reduction of 2.19%. The average optimal reduction was 52.7%, whereas the optimal reduction in the waste bank was 17.5%. The optimal composting reduction was 35.2%. Thus, the existing scenario in 2032 obtained reductions from total landfill gas of 725,498 Gg/year, methane of 193,788 Gg/year, carbon dioxide of 531,710 Gg/year, and NMOC of 8,330 Gg/year. Meanwhile, the optimal scenario for 2032 obtained reductions from total landfill gas of 239.067 Gg/year, methane of 63.857 Gg/year, carbon dioxide of 175.209 Gg/year, and NMOC of 0.412 Gg/year

Abstract

Peningkatan industrialisasi berimplikasi pada pencemaran lingkungan, karena hampir semua industri menghasilkan  limbah B3. Jika tidak dilakukan pengelolaan yang tepat, maka limbah ini mengandung daya rusak yang tinggi bagi lingkungan. Pengelolaan limbah B3 mencakup proses penyimpanan, pengumpulan, pemanfaatan, pengangkutan dan pengelolaan limbah B3 termasuk penimbunan. PT. X merupakan salah satu perusahaan yang bergerak di bidang pengangkutan limbah B3, serta memiliki anak perusahaan yang bergerak di bidang pengumpul limbah B3. Studi ini bertujuan untuk mengetahui jumlah timbulan limbah B3 yang dikumpulkan serta untuk mengetahui sistem pengangkutan dan pengumpulan limbah B3 di PT. X dengan melakukan evaluasi dari sistem pengelolaan limbah B3, dan memberikan rekomendasi pengelolaan limbah B3 sesuai dengan perarturan yang ada. Metode pengumpulan data dilakukan dengan cara observasi dan wawancara dengan beberapa staff di PT. X. Timbulan limbah B3 yang paling besar dalam pengumpul limbah B3 selama satu bulan adalah limbah sludge dengan jumlah timbulan 9.467 kg/bln atau setara 1,87%. Sistem pengangkutan dan pengumpulan limbah B3 di PT. X telah memenuhi ketentuan yang tertera dalam perarturan, namun pada sistem pengumpulan limbah B3, terdapat beberapa fasilitas yang belum memenuhi seperti ketiadaan lab mini, dan luas ruang yang tidak efisien sehingga diperlukan penataan ruang kembali, serta beberapa evaluasi pada bak penampung ceceran, saluran ceceran dan pelabelan pada kemasan.
