Syafrudin Syafrudin Bimastyaji Surya Ramadan Winardi Dwi Nugraha G Samudro Riko Ardiana

Abstract Increasing the amount of waste generation is a problem in every city. This research aims to know the waste transportation and management system to analyze its compliance with the applicable national and local regulations in Indonesia. Demak Regency produced 208 kg/day of waste which this number represent 35.18% of waste generated in Demak Regency from domestic and non domestic sector. The waste is transported and not sorted at sources, as the same with many other cities in Indonesia. Therefore, a proper waste management system is needed for Demak Regency that includes five aspects, which include technical, institutional, financial, regulation, and community aspects. The Environmental Agency of Demak Regency is the institution in charge of waste management in Demak Regency. The analysis shows that improvements are needed to achieve appropriate waste management system in Demak Regency. Therefore, efforts should be made to improve waste management in the Regency, for example, by improving technical performance, human resources, and promoting community-based waste management in the studied area.

Waste Management Strategy as an Effort to Reduce Emissions Due to Open Waste Burning: Demak Regency Case Study

Polish Journal of Environmental Studies (2024)

Badrus Zaman Ika Bagus Priyambada Mochamad Arief Budiharjo Bimastyaji Surya Ramadan Annisa Sila Puspita

Waste management services in the Demak Regency only reached 35% in 2021, resulting in those without waste management services using outdated waste disposal methods such as littering, river dumping, hoarding, and open waste burning.Open waste burning activities are dangerous to the environment because they produce greenhouse gas (GHG) emissions, namely carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O), causing extreme climate change that affects land productivity.This study aims to develop a waste management plan to reduce emissions from open waste burning in the Demak Regency.A transect walk survey determined the waste burning point and the burned waste composition.IPCC 2006 is the basis for calculating emissions and determining emission-reduction strategies using the analytical hierarchy process (AHP).As a result, the projection of open burning of waste in the Demak Regency increases the amount of waste in open burning every year.In 2022, the projected emissions from open burning activities amounted to 48.69 Gg/year, and in 2031 to 55.08 Gg/year.After waste management, the emission rate due to open burning activities in 2022 will be 27.87 Gg/year, and in 2031 will be 31.53Gg/year.There is a considerable decrease of 42.76%.Therefore, there is excellent potential for emissions reduction through improved waste management.

Journal of Sustainability Science and Management (2023)

Mochamad Arief Budihardjo Badrus Zaman Bimastyaji Surya Ramadan Indah Sekar Arumdani

The hazardous and toxic waste material from domestic and office sectors in Semarang is directly disposed of in the Jatibarang landfill without further processing. Appropriate management is needed as has been implemented in the medical sector. Therefore, this study aims to simulate the appropriate hazardous and toxic waste management in Semarang City from the domestic and office sectors. This research was conducted by analysing the existing conditions of hazardous and toxic waste management, followed by establishing a scenario of waste treatment through the projection of hazardous and toxic waste produced. The total waste generation of Semarang in 2031 is predicted to be 283.08 m3/day. It is predicted that Semarang City will require 22 incinerators to treat all of the waste. The ash residue would then be dumped in a hazardous waste landfill covering 0.89 hectares. Hazardous and toxic waste management, specifically from the domestic and office sectors, is expected to prevent adverse impacts on human health and the environment.

Typology and Peri-Urban Development of Yogyakarta City and Surrounding

International Journal of Engineering Technology and Natural Sciences (2021)

Ratika Tulus Bimastyaji Surya Ramadan

The emergence of peri-urban areas as a transition zone between villages and cities has been influenced by the increasing flow of urbanization. Peri-urban is a dynamically developing suburban area with a mix of rural and urban characteristics. This mixture of characters can be classified from land use patterns, demographic characteristics, economy, and availability of public infrastructure services. On the other hand, the impact of urbanization in urban areas provides positive things through economic growth that supports the sustainability of people in urban areas. The city of Yogyakarta is a growth center in the Special Region of Yogyakarta consisting of 14 sub-districts with significant operations in the trade and service sector. The rapid growth of the city of Yogyakarta has triggered the development of the surrounding area which is directly adjacent to several sub-districts in Sleman Regency. This study aims to examine the typology and development of Yogyakarta City and its surroundings in 2015-2019 with the research area being 20 sub-districts in Yogyakarta City and parts of Sleman Regency. The peri-urban zone typological study employs descriptive geographic analysis, overlays, and scoring. According to a series of analyses, there were developments and changes in the peri-urban typology in Yogyakarta area and its environs from 2015 to 2019, which were turned into urban areas in terms of physical, social, and economic factors.

Hazardous Solid Waste Management in Universitas Diponegoro: Planning Towards Environmental Sustainability

Jurnal Presipitasi Media Komunikasi dan Pengembangan Teknik Lingkungan (2022)

Sri Sumiyati Bimastyaji Surya Ramadan Mochamad Arief Budihardjo Aufa Rahma Al-Hafidz Haekal Awliya Muhammad Salman

Universitas Diponegoro has a role in contributing to considerable numbers of hazardous solid waste from academic activities as it is the largest university in Central Java Province, Indonesia. Therefore, improper hazardous solid waste will cause potential disease for humans and pollute the environment. For this reason, proper hazardous solid waste management is urgently needed. This research aims to design hazardous solid waste management for Universitas Diponegoro as a pilot testing study. The research used questionnaires, surveys, in-depth interviews, and observations to construct an appropriate hazardous waste management system. The result showed that hazardous solid waste in Universitas Diponegoro came from 5 sources: education, office, laboratory, supporting facilities, and Pleburan Campus. The estimation of hazardous solid waste produced by the Universitas Diponegoro in 2021 is as much as 100.4 kg/day. The hazardous waste characteristics are toxic, corrosive, flammable, and infectious. In the hazardous management planning that was developed, the design of the waste transportation and storage system at the waste station in the Tembalang and Pleburan campuses has a total investment and operation cost of Rp 6,259,841,999 for 10 years of operation. This design is hoped to enhance the campus's achievement in sustainability efforts.

Integrating Electrokinetic and Bioremediation Process for Treating Oil Contaminated Low Permeability Soil

Bimastyaji Surya Ramadan agus jatnika effendi Qomarudin Helmy

The massive operation of oil mining activities sometimes ignores environmental aspects which may cause contamination in soil and environment. Low-permeability soil oil contamination complicates the recovery process because it requires substantial energy for excavating and crushing the soil. Electrokinetic technology can be used as an alternative technology to treat soil in-situ and improve bioremediation process (biostimulation) through transfer of ions and nutrient that support microorganism growth. This study was conducted using a combination of electrokinetic and bioremediation processes with polarity reversal techniques. Result shows that the application of electrochemistry and bioremediation in low permeability soils can provide hydrocarbon removal efficiency up to 46,3% in 7 days operation. The highest amount of microorganism can be found in 3-days operation, around 2x10^8 CFU/ml using surfactant as flushing agent for solubilizing hydrocarbon molecules. Enhancing bioremediation using electrokinetic process is very potential to recover oil contaminated low permeability soil in the future. (This paper has been presented in ICENIS 2017 which held in Diponegoro University in August 2017. Paper will be published in Advanced Science Letter Scopus Indexed.)

Jurnal Pengabdian Nasional (JPN) Indonesia (2024)

Bimastyaji Surya Ramadan Anik Sarminingsih Nunung Eni Elawati

Sugihmanik Village in Grobogan Regency, Central Java, has many people who work as tofu producers. However, this village is experiencing an environmental management crisis, one of which is the management of sludge resulting from the liquid waste processing process at their wastewater treatment plant (IPAL). One of the proposed solutions is the use of tofu waste sludge as maggot feed, which can provide economic benefits and reduce environmental pollution. The Krida Manik Waste Bank is expected to be a pioneer in managing and utilizing tofu mud to feed maggots which can later be used as animal feed. This study uses a qualitative descriptive method where data is extracted as much as possible to obtain information regarding program management. The results of the activity show that there is potential for managing IPAL sludge using maggots. With the abundant potential of mud, people can use it as a renewable resource. However, capacity development and ongoing assistance need to be carried out to get maximum results.

Municipal infectious waste during COVID-19 pandemic: trends, impacts, and management

International Journal of Public Health Science (IJPHS) (2022)

Iva Yenis Septiariva I Wayan Koko Suryawan Ariyanti Sarwono Bimastyaji Surya Ramadan

The coronavirus disease 2019 (COVID-19) shifts the characteristics of municipal waste. This paper aims to provide an overview of trends, impacts, and management during the COVID-19 pandemic globally. The increase in the generation of plastic waste and infectious waste is a new challenge during the COVID-19 pandemic. It was found that the emergence of plastic waste due to the consumption of food delivery becomes an issue in several countries. Despite the increment of plastic waste generation, the mass layoffs contributed to the decrease in the total urban waste generation in general. In addition to plastic waste, a surge of infectious waste from health facilities and household waste originating from residents infected with the SARS-COV-2 virus was observed. This infectious wastewater potentially leads to environmental disturbances to the rivers and oceans. To tackle global environmental concerns, sustainable waste management is required especially in the development of biodegradable personal protective equipment.

Potential Use of Banana Plant (Musa spp.) as Bio-sorbent Materials for Controlling Gaseous Pollutants

E3S Web of Conferences (2019)

Sri Sumiyati Haryono Setiyo Huboyo Bimastyaji Surya Ramadan

The use of organic waste as bio-sorbent has been carried out by many researchers in the world. Furthermore, the utilization of plants for treating wastewater is also commonly found in various environmental applications. Nevertheless, a review of the ability of banana plants ( Musa spp. ) as bio-sorbent to eliminate gaseous pollutants is rarely found and has not been fully understood. In this paper, lignocellulosic biomass from banana plants (bark, stem, leaves, peels, etc) was identified and reviewed. Sorption potential was discussed and taken from various literature which then evaluated to discuss the potential and ability of banana plants as sorbent material for treating gaseous pollutants. Assessment and measurement methods were also discussed to obtain the best sorbent in removing gaseous pollutants. This research was conducted by reviewing scientific articles that discussed the use of lignocellulosic materials derived from banana plants for absorbing various gases. Almost all articles described the manufacture of adsorbents from banana plants that were used to treat wastewater but not many researchers have tried to develop a commercially adsorbent for gas-shaped pollutants. This research is expected to provide essential information for the readers to develop advanced materials used to control environmental pollution especially gaseous pollutants.
