Abstract

Electronic cigarettes have become a popular alternative for smokers, but research on the pollutants contained in these products remains limited, especially in Indonesia. This study aims to characterise the metal content and radioactive potential of e-liquid from electronic cigarettes marketed in Indonesia. Five e-liquid samples from popular brands were selected based on user surveys and analysed to detect potential hazards. The samples consisted of mango-flavoured saline nicotine e-liquid with a nicotine concentration of 30 mg, which was analysed using neutron activation analysis (NAA) and total alpha and beta radiation measurements. The results showed the presence of heavy metals such as aluminium (Al), titanium (Ti), copper (Cu), nickel (Ni), arsenic (As) and manganese (Mn) with varying concentrations between samples. Aluminium was the dominant metal with the highest concentration reaching 66.256 ± 6.131 µg/g. Although alpha and beta radiation activity was below the detection limit, the presence of certain heavy metals, such as nickel and arsenic, indicates potential health and environmental risks. This study provides valuable insights into the contaminants in e-liquid products in Indonesia, which can be used as a basis for developing regulations to improve product safety.

Abstract

In order to  mitigate the impact of climate change  arising from Greenhouse Gas (GHG) emissions generated from the transportation sector, many countries  including Indonesia, have  initiated to develop policies to encourage environmentally friendly transportation technologies. Electric vehicles  represent a highly sustainable  alternative when compared to conventional vehicles. This study aims to  assess the potential reduction of GHG emissions from the shifting  to electric vehicle utilization on Java Island. The research method was conducted by modeling conventional vehicles until 2033 where there was a transition to electric vehicles throughout the model year and then calculating the GHG emission.  This study employs three scenarios : Business As Usual (BAU), Electric Vehicle Plan (EVP) with existing scenario power plant and Electric Vehicle Plan (EVP) with National Energy Plan (NEP) scenario power plant.  Model results revealed potential GHG emission reductions within 12.11% from the Existing EVP scenario and 12.54% from the NEP scenario against the BAU scenario  due to the shifting usege of electric vehicles on Java island. Based on the model results, it is possible to determine that shifting from conventional vehicles to electric vehicles can reduce GHG emissions from conventional vehicle use.

Abstract

Air pollution in urban areas will increase along with increasing population activity. This study, with the location of Magelang Regency, examines the carrying capacity and capacity of air pollution. The study began with the identification of emission inventories for transportation, household, waste burning and industrial activities. The results of the inventory were used to examine the distribution of air pollutants. The results of the emission inventory in Magelang Regency showed that the transportation sector was the dominant contributor of emissions compared to the waste, household and industrial sectors with an emission load of 2-3.5 times higher. The transportation sector contributes dominantly to the NO2 parameter (94%) and PM parameter (72%), with a relatively similar contribution to the industrial sector in the SO2 parameter (40%). Dispersion modeling showed that the distribution of emissions was even throughout Magelang Regency and showed an accumulation of emissions, especially for the NO2 parameter which was centered on the arterial and collector road networks. When compared to the Ambient Air Quality Standard in Indonesia, the maximum concentration values for SO2, NO2 and PM parameters are still below the quality standard. However, the NO2 parameter needs to be considered because its concentration value has reached 75% of AAQS. Based on environmental carrying capacity, Tegalrejo, Mungkid and Mertoyudan sub-districts are still in good condition, while Secang and Tempuran sub-districts need to carry out mitigation and emission reduction efforts so that air quality is maintained because the air quality index shows moderate and unhealthy quality respectively

Abstract

Sustainable waste management is an important challenge in facing the energy and environmental crisis. One of the solutions that has begun to be developed is the use of biodrying technology, which is the process of drying organic waste using biological activity and aeration to reduce moisture content and increase the calorific value. This study aims to examine the potential of waste biodrying products as an alternative fuel in the cofiring process at the Labuhan Angin Steam Power Plant (PLTU). The methodology used includes the analysis of biodrying product characteristics, measurement of calorific values, as well as technical and environmental feasibility studies in cofiring applications. The results show that biodrying products have a calorific value that is competitive enough to be used as a partial substitute for coal, and can reduce carbon emissions and environmental burden. The implementation of cofiring with waste biodrying has the potential to contribute to the clean energy transition and reduce the volume of waste disposed of in landfills.

Abstract

Air pollution in Grobogan Regency, especially particulate parameters, annually shows an average value of 69% of ambient air quality standards with an average concentration of PM2.5 reaching 38 μg/m³, primarily due to industrial activities, transportation, and the burning of fossil fuels. In the Sugihmanik Village Tofu Industrial Centre, Grobogan Regency, there are 30 home-based tofu SMEs that use rice husks as fuel for boiler furnaces, which produce pollutants such as SO₂, NO₂, CO₂, CO, PM₂.₅, PM₁₀, and TSP. The largest tofu factory in Sugihmanik Village uses 400 kg of rice husks daily. The chimney design, which does not comply with the technical standards of Kepdal No. 205 of 1996, further increases the risk of air pollution. Therefore, the design of an air pollution control device and a chimney redesign are required to mitigate these negative effects. After calculating the emission concentrations and comparing them with PermenLH No. 7 of 2007, only total particle parameter close to the quality standard of 350 mg/m3 with a particulate loading emitted from the furnace of 232 mg/s. By using a cyclone as an emission control device, there is a particulate removal efficiency of 53.05%. With the implementation of air pollution control devices, the ambient air concentration of particulates, previously a peak concentration of around 300 µg/m3, can be reduced to around 68.8 µg/m3.
