Abstract

The rapid development of digital technology has encouraged the banking sector to innovate in digital services. Wondr is an application launched as part of digital transformation. This application offers various advanced features and challenges in retaining users for continuous usage (continuance use intention). This study aims to analyze the influence of E-Customer Relationship Management (E-CRM), E-Service Quality (E-SERVQUAL), and Online Value Co-Creation on the Continuance Use Intention of Wondr users. This research employs a quantitative method with a Structural Equation Modeling - Partial Least Square (SEM-PLS) approach. Data was collected from 382 respondents who are Wondr users using a probability sampling technique. The results indicate that E-CRM and E-SERVQUAL have a positive and significant impact on Continuance Use Intention. Additionally, Online Value Co-Creation, which includes electronic word-of-mouth (e-WOM) and helping behavior, also contributes positively to users' sustainable intention. The implications of this study provide insights for companies to enhance digital banking strategies to maintain user loyalty for Wondr.

Abstract

Petroleum that is produced from several oil wells produces a fluid containing a mixture of petroleum, natural gas and produced water. The produced water usually contains hazardous chemicals such as hydrocarbons, sulfides, ammonia, phenols and other heavy metals. One of the high pollutants in the water produced is phenol. Through a biodegradation process, the contents of phenolic compounds in the produced water are expected to be reduced so that it meets the quality standards of waste water for oil and gas exploration and production activities. This research is development of the results of previous studies using a bioreactor with a larger scale, namely 3 L. The degradation process of phenolic compounds is carried out in optimal conditions, namely: pH 7, temperature 300C, and selected simple media: NP (5: 1) derived from urea and NPK + 0.1% yeast extract. The results of this study indicated that P. aeruginos and bacterial consortium may degrade phenolic compounds very well, which was 5.3 times faster than the previous studies. The biodegradation percentage was 98.40% in P. aeruginosa and 99.03% in bacterial  consortium respectively. The monod kinetics model approach was successfully carried out and gave the value of parameters μMax, Km, YS/X, and μd respectively of 0.6305 hours-1, 0.0280 mg/L, 7 × 10-7 mg/L/ CFU/mL, and 0.00575 hours-1 in P. aeruginosa and 0.3272 hours-1, 0.0355 mg/L, 6.63 × 10-7 mg/L/CFU/ mL, and 0.00279 hours-1 in bacterial consortium. Based on the valuesof these parameters, P. aeruginosa has better affinity and growth.

Abstract

Marine oil spills have bad impacts on the marine biota. Oil spill mitigation that is currently safe, effi cient, relatively cheap and easy to implement is bioremediation, that is degradation of oil spills biologically using microorganisms. Petroleum will be more easily dispersed in water when surfactants are added. The surfactants have the ability to increase the bioavailability of petroleum to facilitate bacteria contact with carbon sources as their feed. This study was intended to test the effect of addition of diethanolamide (DEA) surfactants to improve the ability of bacteria to degrade hydrocarbon compound in the seawater media. The biodegradation experiment was conducted in 8-liter seawater media and the ability of DEA surfactants to reduce surface tension, oil content, pH and nutrients on days 0, 1, 3, 6 and 10 were observed. GC-MS analysis was conducted to detect chemical component changes in petroleum. A bacterial consortium of Enterobacter sp., Pseudomonas sp., and Raoultella sp. was utilized. The oil was degraded up to 65.52% with biodegradation rate k = -0.1054 t in the media added with DEA surfactants. The aliphatic fraction detected was C17-C31 n-alkane compound and after biodegradation it became C20- C31. The results showed that DEA surfactants were able to improve the ability of bacterial consortium to degrade petroleum.

Abstract

The purpose of this research is to obtain the optimum condition of phenol biodegradation in arti􀂿 cially produced water using Pseudomonas aeruginosa. The screening of medium in the highest phenol degradation at 99.85% in medium M5, followed by M1, M4, M3, and M2, at 99.83%, 28.47%, 27.64%, and 0.09%, respectively, during the 24 hours incubation time. Medium M5 and M1 are relatively expensive if applied in the 􀂿 eld, thus optimization of incubation time, temperature, pH, and the adding of oil is needed in the treatment parameters affecting the phenol biodegradation process using an easy and cheap medium, M4. This research resulted in phenol biodegradation percentage at optimum condition for 2 days incubation, pH 7, and temperature 30°C, was 99.98%.The adding of oil at optimum condition: 100 mg/L could degrade phenol waste to 28.01%.

Abstract

This research is aimed at improving the ability of oily wastewater biodegradation through the ozonation method, where ozone will oxidize organic compounds in the oily wastewater that are diffi cult to be degraded by bacteria so that the structure becomes simpler. The ozonation process is done by using a corona-discharge ozonator and semi-batch reactor, and the process is varied by ozone dose and pH value. The ozonation process is then followed by a biodegradation process, where the bacteria that is used is Pseudomonas sp. This study also observed the effect of surfactants in supporting the biodegradation processes. An indicator of research success is the increase in the biodegradation percentage of the sample, followed by an increase in the value of the constant rate of bacterial growth. The research results shows that the ozonation method and the use of surfactant can support the oily wastewater biodegradation process. This is shown by the value of the biodegradation percentage and the constant rate of bacterial growth results, in which respective values are able to reach 86,787% and 0,339 at the optimal operating conditions (ozone dose of 0.53 g/h; pH 7; Bios-H surfactant concentration 500 ppm).

Abstract

Contamination of petroleum waste has endangered the environment, yet its processing technology isnot effective and effi cient. It is becaused that by petroleum waste is diffi cult to be degraded by bacteria dueto many complex bonding compounds containned in this oil waste. Therefore, this study used ozonationas pretreatment process with the aim to enhance the biodegradation process. The variations in operatingconditions performed in this study are dose of ozone and pH. The bacteria used as a degrading agent isthe Pseudomonas aeruginosa. The results show thatozonation process can the enhancebiodegradabilityas indicated by the increase of degradation and population growths of bacteria. In addition, the abilityof the bacteria P. aeruginosa in degrading petroleum waste is varied with ozone doses and pH values.The highest percentage of degradation achieved at dose of 0.53 g ozone/h and pH 7.48 are approx from56.52% without ozone pretreatment to 79.32% after 7 days incubation.

Abstract

Oil sludge from petroleum industry effluent is classified as hazardous waste and requiredspecial treatment before discharge to the environment. Biodegradation using bacterialactivities is a general treatment for oil sludge processing. However, the bacterial abilityin oil sludge biodegradation is blocked by non-aqueous phase liquid of oil sludge. Twopossible ways of enhancing the bioavailability of oil sludge are surfactants application and slurry bioreactors system. The objective of this study is to obtain the surfactant which can increase oil sludge biodegradation using simple slurry bioreactor. The surfactant selection obtained Emulsogen LP (58% effectiveness) which was examined based on HLB value, nonionic character, and surfactant effectiveness. Emulsogen LP is readily biodegradable which reached 93% biodegradability in 15 days. The biodegradation test showed that Emulsogen LP addition on its Critical Micelle Concentration (10 mg/L) enhanced oil sludge biodegradation in 3 bacterial cultures of Pseudomonas aeruginosa, Bacillus subtilis, and Actinobacter baumanni after 48 hours. By surfactant addition, oil sludge biodegradation reached 37-49% whereas without surfactant addition it only reached 28-33%. The highest oil sludge biodegradation was obtained in P. aeruginosa cultures with Emulsogen LP addition (49%). The surfactant addition had no effect on microbial growth. Moreover, P. aeruginosa population was increased by surfactant addition.
