Abstract

In recent years, concerns regarding to wastewater sludge disposal have increased globally. Production of sludge has increased recently due to the growth of population. Wastewater sludge classified as a hazardous substance, it is not easy to dispose because of certain treatment is required. Typically, sludge is treated at secured landfill which its limited in availability and expensive. On the other hand, wastewater sludge originated from biological treatment contains organic substance that can be converted into alternative energy resources. A technology is needed that is able to reduce the volume of sludge and convert sludge into energy source. We present an overview of various technologies that can be used for conversion of sludge into energy resources. Those technologies are anaerobic digestion, pelletization, combustion, pyrolysis and gasification. Progress and challenges of each technology is presented in detail. A summary of sludge characteristic originated from different source will be discussed as well. Emissions and residues that determines the environmental impact is also considered. Referring to some previous research, it known that wastewater sludge, as unwanted product, has the potential to become future energy resource. This potential can only be used properly if the method of conversion are effective and efficient.

Abstract

Waste is one of the big problems often faced by metropolitan cities like DKI Jakarta. The Jakarta Environment Agency's research stated that DKI Jakarta produces 7500-tons of waste per day with 60.5% coming from residential. Therefore, the DKI Jakarta government initiated the Sampah Tanggung Jawab Bersama (SAMTAMA) to mobilize residential people to manage waste from its source at certain locations as a pilot, one of locations is RT 10 / RW 03 Cempaka Putih Timur. RT 10 / RW 03 Cempaka Putih Timur is the RT that is considered optimal in implement the SAMTAMA program. Based on this, the objectives of this study are: (1) to find the existing condition of SAMTAMA program; (2) to measure the waste generation, composition, and reduction potential in the implementation of SAMTAMA program. The method implemented in measuring using SNI 19-3964-1994 which is carried out for 8 consecutive days. Waste composition is classified based on SNI 19-3964-1995, supplemented with components of B3 waste and diapers. The results of the analysis show that the average of waste generation is 14.99 kg/day where the treated waste is 11.36 kg/day and the untreated or residual waste is 3.63 kg/day with the largest composition is food waste with 10.66 kg/day (71%). With SAMTAMA Program implementation, the waste potential reduction can reach 0.019 kg/day/person.

Abstract

Environmental Management effort in conservation will be required to diverse natural resources value, and as a form of favouring the sustainability of biological natural resources and its ecosystem utilization in City Forest of Telagasari (HKTs). HKTs have been designated as a green open space and it is developed as a protected area and education center of biodiversity in Balikpapan City. Data collection was done by direct observation method on terrestrial fauna and flora. There are 133 kind of flora in HKTs (11 flora are protected by IUCN and 14 flora are  protected by PP RI in SK/54/Pertanian/1972) with a Shannon-Wiener Index (H’) 3.04 for ‘semai’ category, 3.02 for ‘pancang’, 3.02 for ‘tiang’, and 1.86 for ‘pohon’ category. The numbers of avifauna that had been recorded in city forest of Telagasari are 35 species (7 has important protection status), with a Shannon-Wiener Index (H’) of 2.762. The numbers of mammals that had been recorded in city forest of Telagasari are 7 species and 21 individuals, with H’ mammals of 1.5. This inventory data and information can be used to support the conservation, as an environmental management effort. The baseline of biodiversity and conservation status in HKTs Balikpapan will be measured as a key parameter for the implementation of biodiversity protection program. The strategic planning and program that are proposed for next fifth year for HKTs may give a positif impact for biodiversity and conservation in HKTs.

Abstract

Ambient Air Quality Monitoring (AAQM) must be conducted by Industrial Estate Management, according to legislation and regulation in EIA (Environmental Impact Assessment) Report. AAQ test parameter are Sulfur Dioxide (SO2), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Ozon (O3), Hidrocarbon (HC), PM10, PM2,5, Total Suspended Solid (TSP), and Lead (Pb). Industrial Estate Management has an extensive role in AAQM, analysing and organizing better environmental policies. The data of Jababeka Industrial Estate (JIE) AAQM was seized from EIA Report each semester from year 2015 to 2018 and analyzed using openair model. A review of AAQM and Management in other industrial estate was done as a lesson-learned and insight to improve the AAQM System in JIE. Openair model can analyze the AAQ data with meteorological data around the sampling point area, and visualize it through the pollution rose function. The limited data of AAQM and weather, will limitate the result and analysis. The future research must aims to make a real-time/continuous AAQM and meteorological data to get more accurate and comprehensive data modeling and analysis.

Abstract. Emissions are the result of human activities that increase the concentration of greenhouse gas gases such as CCl2F2, CO2, N2O, and  CH₄, Increasing the attention of the gases above will increase the greenhouse effect which ultimately increases the earth's temperature. The existence of a waste management site can produce greenhouse gas emissions from vehicle transportation, composting processes, TPA to recycling. One of the roles of Flamboyan's TPS3R is to reduce the amount of plastic waste by recycling and composting and the residue will go to Cipeucang TPA for landfilling. This is an effort to reduce the amount of organic and non-organic waste, but the recycling, and composting. Landfilling processes can produce CO2 in the waste processing and distribution process, so it is necessary to calculate the amount of CO2 from the baseline management of municipal solid waste that will be compared with alternative municipal solid waste scenarios to see the conclusion of the analysis using the Waste Reduction Model (WARM) application. Objectives: The objective of this journal is to calculate the greenhouse gas emission and energy use of TPS3R Flamboyan. Method: The secondary data was obtained from TPS3R Flamboyan’s management. The writer use description analysis.
