Objectives: Penile carcinoma (PC) is a rare disease with considerable physical and psychological impact. To date, there is no data regarding PC prevalence and characteristics in Indonesia. This study aimed to analyze the characteristics of patients with PC in Indonesia and determine cumulative survival rates and time to disease progression. Methods: This was a retrospective study of all patients diagnosed with PC at Cipto Mangunkusumo General Hospital from 1995 to 2014, with a minimum of 1 year follow‐up. The outcomes of the study were cumulative survival rates and time‐to‐disease progression. Results: Ninety‐three subjects were recruited, with a mean age of 49.44 ± 13.62. Inguinal lymph node dissection (ILND) was performed in 49 (53%) patients. The mean survival in the ILND group was better compared to the non‐ILND group (80.7 months vs. 67.1 months; p = 0.032). Time‐to‐progression in the ILND group was significantly longer than in the non‐ILND group (71.7 months vs. 54.3 months; p = 0.022). No significant difference in survival between the total and partial penectomy (PP) groups was observed (p = 0.701). Time‐to‐progression in total penectomy (TP) was significantly longer than in PP (68 months vs. 56.0 months; p = 0.023). In Cox‐regression analysis, after adjustment of other variables, history of ILND, higher stage of cancer, and older age were found to affect the survival of patients. Conclusion: ILND in PC led to better survival and reduced disease progression. The type of penectomy is only associated with progression but not survival. TP had a longer time to disease progression compared to PP. [ABSTRACT FROM AUTHOR]

Gold nanoparticles (AuNPs) synthesized through green synthesis have the potential for application in various biomedical sectors. This study demonstrates the optimization, synthesis, and characterization of AuNPs using marine microalga, Synechococcus moorigangae strain InaCC M208, isolated from Jakarta Bay, Indonesia. Optimization of the synthesis process focused on three parameters: temperature, ratio of precursor-to-extract, and incubation time. The AuNPs were characterized using various techniques, including UV–Vis spectroscopy, TEM, XRD, FT-IR, PSA, and EDX spectroscopy. The ethanol extract of S. moorigangae InaCC M208 was responsible for the reducing and stabilizing agent during the AuNPs synthesis. The optimized conditions for synthesis were found to be a precursor-to-extract ratio of 1:1 at 37 °C for 22 h. The UV–Vis spectra of the synthesized AuNPs (Syn-AuNPs) exhibited a surface plasmon resonance at 552 nm. According to FT-IR, various phytoconstituents from the extract contributed to the reduction and stabilization of Syn-AuNPs. Syn-AuNPs exhibited a spherical form with an average size of 8.2 nm and a zeta potential of − 21.5 mV. Notably, these Syn-AuNPs exhibited antibacterial efficacy against the pathogenic Staphylococcus aureus InaCCB4, Escherichia coli InaCC B5, Klebsiella pneumoniae 1617, Pseudomonas aeruginosa N90PS, and E. coli 8654. Additionally, Syn-AuNPs also demonstrated antioxidant capacities against DPPH radicals. It is possible to readily scale up this environmentally friendly synthesis technique for future studies, and AuNPs produced through microalgae-mediated green synthesis have substantial promise for nanomedicine applications.

Renal transplantation is the preferred treatment for end-stage renal disease because of its association with improved survival and quality of life. The debate over multiple renal arteries (MRA) vs a single renal artery regarding kidney function, posttransplant complications, and graft and patient survival remains ongoing. Our goal was to determine the 1-year graft survival rate among renal transplant recipients with MRA at Cipto Mangunkusumo Hospital in Jakarta. A retrospective study was conducted between January 2012 and December 2020, including all kidney transplant candidates with MRA. Data on graft survival, patient demographics, previous renal transplantation, duration of hemodialysis, and delayed graft function were collected and analyzed using SPSS 24. Kaplan-Meier plots and Cox regression analyses were used to determine risk factors for 1-year survival. Among 752 renal transplant recipients, 104 cases had MRA. The majority were men (71.5%), and the median age of recipients was 47 years. One-year graft survival was observed in 96% of cases, whereas patient survival was 97.7%. No significant difference was found in graft survival based on the number of arteries (single renal artery vs MRA), length of hemodialysis, or previous renal transplantation. However, delayed graft function was significantly associated with graft survival. This study highlights that 1-year graft survival in renal transplant recipients with MRA is not significantly affected by the length of hemodialysis before surgery or previous renal transplantation.

Economic and urban developments have contributed more plastic waste and are also dominated by organic waste. The organic content and high caloric content of the waste characteristics in Indonesia support the selection of an appropriate waste to energy technology. At this time the concept of waste to energy is being developed in a number of developed countries as a method for managing waste and strategy to improve waste management and reduce environmental impacts. This study aims to determine the level of public acceptance towards waste to energy technology enabling waste to energy to be adequately managed by increasing public awareness. A random sampling was carried out on residents in Jakarta using a hybrid method. The results showed the percentage of total variance of the three factors, namely socio-economic, environmental impact and development was 72.11%. Socio-economic refers to the ability of the community to see opportunities, environmental impact refers to community awareness, and development refers to the technical aspects of waste to energy development. Of the three factors, socio-economic factor became the most determining factor to the waste to energy public preference and acceptance. The education level and potential income from the project can be determined as the most determining factors for developing and implementing waste to energy in Jakarta. The binary probit regression analysis model approach is used for the willingness to accept waste to energy by grouping models from communities with different classes formed from cluster analysis, namely overall respondents (model I), low participation (model II), pro-sustainable environment (model III), and pro economy and society (model IV). In addition, the most significant feature for each model was the increase in public knowledge about waste to energy technology to be applied in the future. This is also a lesson for other regions and countries that will apply waste to energy technology to consider non-technical aspects to increase public acceptance, particularly in terms of the strategic issue claiming the harm of the waste to energy.

The condition of the Coronavirus Disease 2019 (COVID-19) pandemic in 2020 characterizing DKI Jakarta, Surabaya, and Yogyakarta Provinces which have a high population density in 2019, necessitates implementing Large-Scale Social Restrictions (LSSR) to control or break the chain of the spread of COVID-19. The LSSR policy that limits community activities, be it business activities, transportation, and the industrial sector, will impact social activities and the environment due to the reduced intensity of community activities. Therefore, this study aimed to determine changes in the carbon monoxide (CO) levels in Jakarta, Surabaya and Yogyakarta during the prepandemic and during the pandemic. The method used is the tropospheric CO concentration extracted from the Sentinel-5P satellite data. The CO data were retrieved and calculated using Google Earth Engine. The COVID-19 pandemic reduced CO level by 19.7%, 14.9%, and 21%, respectively. The paired t-test shows no significant difference from before the COVID-19 pandemic, with a significance of 0.05. The highest pre-pandemic average and total CO concentration levels were 0.042 and 1.0198 mol/m2 in Yogyakarta, respectively, whereas the lowest during the pandemic were 0.02845 and 0.6828 mol/m2 in Surabaya. Overall, the three cities have a weak relationship between CO level and precipitation as well as temperatures and CO level. [ABSTRACT FROM AUTHOR]

The bird community in urban areas indicates the species-specific adaptability to urban conditions such as the increase in man-made habitats. Urban adapters and urban exploiters, two groups that make up most of the urban birds, were assessed to determine their suitable habitat and explain their distribution, as well as to determine the environmental predictors for the two bird groups assemblages in Depok, one of Jakarta's satellite cities. We used the point-count method to survey the birds in three habitat types, green spaces, residentials, and roadside, and then we used Maximum Entropy (MaxEnt) to analyze the species distribution modeling. We also the predicted habitat distributions for the urban adapters and urban exploiters based on several environmental predictors. Our results suggest that both urban adapters and urban exploiters were abundant in residential areas. Eurasian tree sparrows (Passer montanus) and cave swiflets (Collocalia linchi) were the most common species in all three habitat types. On average, canopy cover was most extensive in green spaces followed by residential and roadside areas. Urban exploiters were likely to have a high suitability extent compared to urban adapters. The distributions of both groups were affected by the distance to perennial water, then by land function for the urban adapters, and distance to patches for the urban exploiters. The presence of urban adapters and urban exploiters in residential areas suggests that home gardens supported critical habitats when green spaces were unavailable. [ABSTRACT FROM AUTHOR]

This study aimed to determine sludge sewage and its potential as a solid fuel with a case study of Jakarta City. It was conducted by taking the samples of fecal sludge for three consecutive days at peak hours. The age of the sludge used in this study was 0 d, which was taken at the wastewater treatment plant (WWTP), septic tank, and open defecation. The generation of fecal sludge in Jakarta in 2020 could reach 2,129 ton/d. The quality of fecal water discharged into the environment can improve from year to year, accompanied by poor treatment. Based on the quality standards of wastewater produced from WWTP, septic tanks and open defecation do not meet the quality standards of wastewater. If this condition continues, it will pollute the water bodies in Jakarta. One alternative that can be done is to use fecal sludge as fuel. The feces water content in this study reached 74.14% ± 4% (WWTP); 68.14% ± 3% (septic tank), and 82.49% ± 1%. The results of the measurement of the calorific value of WWTP, septic tank, and open defecation reached 2,620.67 ± 54 kkcal/kg; 2,853 ± 130 kkcal/kg; and 2,298.67 ± 99 kkcal/kg, respectively. The amount of energy used for Jakarta can reach 1,024,049 MJ/d. The 90% significance analysis of BOD, COD, and air content parameters affects the calorific value of feces sludge.

There are still many people in Jakarta who throw their garbage into the river, resulting Jakarta city never being absent from the problems of river water pollution and flooding. Pesanggrahan River and Grogol River are some of the big river surrounded by high popullation area. All waste originating from the Pesanggrahan River and the Grogol River is dumped into the Bantar Gebang Landfill. This study aimed to reduce waste entering landfills are by making use of waste that still has economic value. The method used in decision making from various alternatives of the river waste utilization are utility theory and compromise programming. It takes planning to find out the composition and generation of solid waste from those rivers and to determine the potential use of river waste and the action to minimize and handle the river waste. Utilization of river waste that can be applied based on the composition of most waste is open windrow composting and plastic shredding. It is important to concern about river waste since Indonesia has various polluted river, especially by solid waste. By implementing a good river waste utilization, the waste that enters the landfill will be reduced and in line with reduced pollution to the aquatic environment. [ABSTRACT FROM AUTHOR]

Plastic pollution in the ocean primarily originates from the land-derived mismanaged plastic waste that is transported by rivers. This study aimed to estimate the plastic litter generation in the surface water in Jakarta and Indonesia. A field survey was conducted at six riverine sampling points (upstream to downstream) and three holding facilities of the litter in Jakarta during the rainy season. The Jakarta Open Data database was used to estimate the tonnage of plastic litter. By mass, plastic comprised approximately 74 % of the anthropogenic litter in rivers and 87 % in holding facilities. The riverine plastic proportion slightly increased downstream. Approximately 9.9 g/person/day of plastic litter was discharged into Jakarta's surface water during rainy season and recovered by floating booms. To reduce plastic pollution and its severe impacts on aquatic ecosystems and human health, further field investigation is necessary to design an effective clean-up system and litter-prevention strategy. [Display omitted] • Plastic comprised 74 % of riverine anthropogenic litter by dried-mass. • Plastic proportion slightly increased downstream. • The holding facilities had a higher plastic proportion (87 %) than rivers. • Plastic litter recovered from floating net boom was up to 205 kg/day. • Plastic leakage into the surface water was 9.86 g/person/day in the rainy season.

Purpose: The current study aims to compare the effectiveness of pre-urodynamic single-dose levofloxacin and post-urodynamic levofloxacin for three days related to the incidence of urinary tract infections post-urodynamic examination.Materials and Methods: This is a single-blind randomized clinical trial conducted in three outpatient urology centers in Jakarta: Cipto Mangunkusumo General Hospital, Siloam Asri Hospital, and Persahabatan General Hospital using a consecutive sampling method between July 2019 - February 2022. The outcome of the study is the incidence of urinary tract infections in both treatment groups. Urinary tract infection was defined as a patient with one or more clinical symptoms of lower urinary tract infection and one or more urinalysis parameters positive for urinary tract infections. Chi-square was used to evaluate the association where p < 0.05 was used to determine statistical significance.Results: A total of 126 patients (63 patients in each arm) were included in the evaluation and analysis. Overall, urinary tract infections were detected in 25 cases (19.8%), 12 patients from the pre-urodynamic antibiotic group (9.5%) and 13 patients from the post-urodynamic antibiotic group (10.3%) (P = .823). E.coli was the most common bacteria found in the urine culture.Conclusion: There is no significant difference between a single dose of 500 mg of Levofloxacin administered one hour before the urodynamic study and a once-daily dose of 500 mg of Levofloxacin for three days following the urodynamic study related to urinary tract infections prevention post-urodynamic examination.
