Gas stations are a common source of groundwater contamination by petroleum hydrocarbons. These pollutants are a health concern when people come in contact with the contaminated water when pumping from polluted wells, for example. However, in Indonesia this problem remains largely ignored, despite some prominent leakage incidents at gas stations. The purpose of this study is to investigate the groundwater contamination by petroleum hydrocarbon from gas station in the greater Yogyakarta area in Indonesia. Screening criteria such as construction standards, reported leakage incidents, and geological and hydrogeological condition were used to identify gas stations with high risk of water contamination by petroleum hydrocarbon. Gas station with close proximity with dug wells in which its water had been used for human daily consumption was selected for further analysis. Groundwater samples were then collected from dug wells located in the vicinity to this selected gas station and then analyzed for benzene, toluene, ethylbenzene, xylene (BTEX) by gas chromatography/mass spectrometry. Of the six sampling points, BTEX were detected with concentrations ranging from 0,008 to 25,631 ppb. Concentration of benzene at sampling point 3 exceed the standards of Indonesian drinking water quality and WHO. These findings indicate that BTEX groundwater pollution may be a health hazard of currently unknown proportion in the greater Yogyakarta area. It is recommended to assess health risk associated with human daily consumption of BTEX polluted groundwater and also to test groundwater at all gas stations in this area and remediate those affected by BTEX.

The development of transport activities that can increasing of contaminants in the air. This would lead to the influence of environmental conditions and health. UII campus is a campus that is committed to applying the campus of low-emission and environmentally based. This study analyzes the density of traffic that occurs in the area of UII Kaliruang. This research analyzed the relationship with environmental conditions of factors: noise, vibration, NOx, and TSP (Total Suspended Particle). Traffic density in the UII is still relatively medium speed (service A). This study shows that the condition of the environment caused by transport is a positive relationship, that the higher the intensity of transport will decrease the environmental condition. Environmental condition that occurs due to transport to NOx, noise and vibration are still in tiers below the quality standards. While the TSP at noon already classified in a higher intensity. Although the integrated campus UII still in a modest scale, but the development for follow-up treatment can cope with environmental conditions worsened

Salah satu komponen berat di dalam minyak bumi yaitu parafin/wax akan mengendap pada dinding pipa transmisi apabila temperatur berkurang seiring minyak yang ditransmisikan mendekati permukaan bumi. Selain penanganan secara mekanis dan isolasi termal juga terdapat penangan dengan penambahan bahan kimia sejenis surfaktan untuk menurunkan tegangan permukaan kemudian membentuk mikroemulsi sehingga minyak dapat larut di dalam air begitu sebaliknya. Biosurfaktan menjadi alternatif menjanjikan yang ramah lingkungan, relatif mudah untuk dikembangkan dengan biaya yang relatif lebih murah. Tujuan dari penelitian ini yaitu menemukan isolat bakteri penghasil biosurfaktan menggunakan metode isolasi bakteri dari deposit lilin di dalam pipa transmisi minyak mentah kemudian diseleksi bakteri penghasil biosurfaktan. Didapatkan isolat bakteriEnterobacter gergoviaedanBurkholderia cepacia. Bakteri yang berkaitan dengan penghasil biosurfaktan disini yaitu bakteri Burkholderia cepacia yang memiliki waktu generasi 68,4 menit dengan konstanta laju pertumbuhan 0,61 per jam.

High free fatty acids in waste cooking oil can interfere with the re-use of the cooking oil. Therefore, the absorption technique is one way that can reduce the free fatty acids contained in waste cooking oil. Aim: The purpose of this study is to find out the ability of Reactivated Spent Bleaching Earth (RSBE) to adsorb free fatty acids contained in waste cooking oil to be biodiesel products. In this study, waste cooking oil was collected from fried food sellers in Bekasi, while spent bleaching earth (SBE)-one of the solid wastes produced by refinery oil palm industry as an adsorbent-was from the palm oil industry PT X. For Reactivated Spent Bleaching Earth (RSBE), the redundant used 0.7 M HNO3. To obtain the optimum products, The redundant applied the variation of time (i.e., 30, 45, 60, 75, and 90 minutes) and concentration (6%, 9%, 12%, 15%, and 18%). Methodology and results: Results indicated that the time variation of temperature 90 minutes were the maximum and the concentration of 15% were the optimal combination to reduce free fatty acids 0.65%. Conclusion, significance, and impact of study: The values of water and ash contents of RSBE also meet the quality standard as activated carbon and can be used as an adsorbent for the purification of waste cooking oil. The oil content in SBE is less than 3% and is considered not to be a toxic hazardous waste. Therefore, it can be reused without pre-treatment. In addition, the redundant found that there were changes pore on the surface of the SBE, both activated and not activated. To conclude, SBE can be used as an absorbent to absorb the fatty acids in waste cooking oil.

The degradation of life due to the COVID-19 pandemic, whether physiological, psychological and economic, requires a comprehensive thought on community resilience according to the capacity and context. The placemaking experiences in The Maguwoharjo International Stadium (MIS) area indicates a positive community response through sports, recreation, and informal businesses than enliven the area. This study aims to strategies for reinventing existing activities using a placemaking approach, specifically through three variables, the Person, Procedures and Place. The hope is that when the MIS area is designed and developed as a Tourism Special Economic Zone (SEZ), these actors remain included a development stakeholder. This study using qualitative descriptive methods and categorized into primary and secondary activities in public spaces. The results highlight three points: alignment of MIS with MICE-based tourism policy, the importance of placemaking for physical resilience and informal business, and the need for landscape element to mitigate pollutants.
