Green Synthesis and Characterization of Silver Nanoparticles Derived from Ethanol Extract of Sappan Wood

/in /by

Silver nanoparticles had been synthesized through the reduction process using an ethanol extract of sappan wood (Caesalpinia sappan L.) as a bioreductor.  The variation of the formula used is a mixture of the ethanol extract of sappan wood with a 2 mM AgNO3 solution in a volume ratio of 1:1, 1:2, 1:3, and 1:4. The results showed that the UV-Visible spectrophotometry confirmed that the volume ratio of 1:1 was the optimum formula with an absorbance value of 1.243 at the maximum wavelength of 446 nm. Particle size analysis using Zetasizer Nano ZS revealed that the synthetized silver nanoparticles had a particle size of 618.1 nm. The hydroxyl group (OH) had a important role in the nanoparticle formation process, according to functional group characterization using FTIR. Due to silver nanoparticles tendency  to agglomerate, the SEM image of the silver nanoparticles showed a variety of sizes and forms.

The Use of Temperature and Waste Diapers in the Demulsification Process of Crude Oil Samples

/in /by

Currently, the oil wells in Indonesia are getting older, the older the oil well shows the greater the water content, which will cause the formation of a water-in-oil emulsion. The presence of emulsion that occurs in crude oil will cause a decrease in oil quality and oil production. Therefore, a demulsifier is needed to overcome these problems. Because the existing demulsifier are still very few variants and are not environmentally friendly, a new type of demulsifier that is environmentally friendly is needed. Baby diapers can be used as a new type of demulsifier because baby diapers contain Polymer Superasorbent (SAP) which can absorb 200 times water [1]. Superabsorbent Polymer has inert and hydrophilic properties with the working principle of absorbing and trapping water in the emulsion formed on crude oil. In this experiment, the author uses baby diaper waste to separate water and oil in the emulsion formed on the P#441 crude oil sample at a temperature of 26.70C, 400C, and 500C with a centrifuge with a speed of 500, 1000, and 1500. RPM in 1, 2, and 3 minutes. Demulsification process occurs faster in crude oil sample at a temperature of 500C because of high temperatures can accelerate the process demulsification. The use of baby diapers as nashi demulsifier is in its early stages and can be developed further, but it has been proven to accelerate the demulsification process in the emulsion formed by sample P#441.

The Analysis of the “Buy Now, Pay Later” Use Intention in Indonesia

/in /by

The Rapid technological and informational advancements have an effect on the financial industries. One of its offerings is financial technology, sometimes known as fintech. In 2018, a number of fintech startups introduced products that enable clients to make installment payments without credit cards. This is referred to as Buy Now, Pay Later (BNPL). Then, numerous technology firms, such as Traveloka, Shopee, and Gojek, embrace this approach to round out their payment alternatives. The market for BNPL in Indonesia is quite promising. Demand for BNPL is quite high, as seen by the rapid expansion of BNPL providers in Indonesia. Many companies, including Traveloka, Gojek, Shopee, and others, demonstrated a rise in BNPL product usage. Using the Technology Readiness and Acceptance Model, this study examines the Buy Now, Pay Later usage intent (TRAM). This study concludes that technology readiness, perceived usefulness, and perceived simplicity of use influence the intention to use a BNPL product, with perceived usefulness having the most direct impact on users’ intentions.

Analysis of Chloramphenicol in Shrimp Using Standard Addition Method Based on Diazotization

/in /by

This research aimed to determine the concentration of chloramphenicol in shrimp using the standard addition method based on the diazotization reaction using Zn powder as a reducing agent of chloramphenicol, followed by the use of N-(1-naphthyl) ethylenediamine dihydrochloride as a coupling agent and measured at 565 nm. Based on the test, the shrimp sample was found to contain 1964.91 mg/kg of chloramphenicol and it exceeded the requirements set by the European Commission which was 0,15 mg/kg. The limit of detection (LOD) value is 0.19 mg/mL and the limit of quantitation (LOQ) value is 0.64 mg/mL. The correlation coefficient (R2) was 0.9991 for the concentration range of 0-50 ppm. The analysis of the results showed that the %recovery in shrimp analysis using this method was 87.41%-107.73% with an average of 109.38%.

Analysis of Correlation between Hyper-Uricemia and Renal Resistivity Index in Normoglycemic Normotensive Patients

/in /by

Introduction: Hyperuricemia is associated strongly with the development of renal disease and progression. Medical therapy decreases serum uric acid levels by inhibiting the enzyme xanthine oxidase.

Objective of the study: To evaluate correlation of mean uric acid level and Renal Resistive Index in normoglycemic and normotensive adult subjects.

Material and methods: This descriptive cross-sectional study was conducted in THQ Hospital Fort Abbas during 31-10-2018 to 30-04-2019. One hundred (n=100) non-diabetic, non-hypertensive, recently diagnosed hyperuricemic otherwise healthy subjects irrespective of gender between age 20-40 years were included in the study.  After complete history taking and full physical examination laboratory testing including: serum uric acid, serum creatinine to exclude renal decompensation patients, fasting blood sugar and 2 h post prandial were advised.

Results: 55.0% (n=55) of patients were males with the mean age of 33.40 years ± 3.85 SD and 45.0% (n=45) of patients were females with mean age of 34.67 years ± 3.33 SD. Cumulative mean age was 33.97 years ± 3.66 SD. The mean value of the RI of the renal arterial vasculature was 0.765 ± 0.0155 SD. The maximum, minimum and range values of the RI were 0.79, 0.74, and 0.04 respectively. The mean serum uric acid value found to be 10.947±0.562 SD. The maximum, minimum and range values of the RI were 0.79, 0.74 and 0.05 respectively. Correlation between the serum uric acid and renal arterial RI prior to the medical therapy and 3 weeks after therapy. A positive correlation was found between both values with a Pearson’s correlation coefficient = 0.103 and p-value 0.308.

Conclusions: It is concluded that that medical treatment of hyperuricemia results in lowering of serum uric acid which correlates with the decrease in renal resistive index.

Avoiding Ambiguous Framework in Distance-based Formation Control Using Virtual Followers

/in /by

In this study, we develop a shape formation controller based on regular distance-based control law. As distance rigidity theory may not be successful in achieving desired shape when the control system defined under minimally rigid graph. As a matter of fact, the formation may converge to ambiguous framework when the group of mobile robots did not initialize in proper way. This is a well-known issue with distance-based formation control while there are multiple equilibrium points in the dynamics. We introduce a new controller by adding virtual constraints to the system. The performance of control system is exemplified through numerical simulations and the convergence to the desired formation for all initial conditions validated with stability analysis.
