Abstract

River water fluctuations affect the amount of inundation that occurs. The study aims to obtain a cross-section of the river channel to drain runoff water so that the runoff due to maximum rainfall does not cause puddles. The Ketupak river flow cannot drain flow during the rainy season. Besides that, there is also a lot of sediment, garbage, stems and branches that interfere with the Ketupak river flow. Therefore, it is necessary to rearrange the river channel. From the results of calculations based on rainfall data, it is necessary to increase the cross-sectional area of the river.

Abstract

In HPHT environments, the mechanism of CO2 corrosion faces a challenge as an effect of chemical-physical reactions on the metal surface. The presence of other elements in the CO2 system complicates corrosion behavior. To provide a realistic mechanism for corrosion process, some corrosion prediction models have developed software using fundamental theories such as electrochemical reactions and thermodynamics theories. Existing methods to predict corrosion rate models in HPHT environments have shown reasonable results. This paper reviews software of corrosion predictions which calculate corrosion rate based on mechanistic theories that study effects of H2S, acetic acid (HAc) concentrations, shear stress, pH in temperature from 25oC – 100oC and pressure from 1–10 bar. From the simulation, corrosion rate increased significantly in the high pressure CO2 environment. Corrosion rate at pH 4 increased to 30 mm/y at a temperature from 15oC to 90oC. While at pH 8 corrosion rate reached 4 mm/y. This lower corrosion rate indicated a tendency for deposits formation at higher pH. Corrosion rate behaves in a different mechanism at high temperatures. The corrosion rate decreased to 4 mm/y when the temperature increased to more than 90oC. Effects H2S gas and HAc were identified to increase corrosion rate. Both elements provide extra cathodic reaction and create limiting current density in the cathodic reaction process based on polarization sweep models. However, the polarization graph calculated using corrosion models could not display passive behavior in the anodic polarization process. Thus, further, improvement should be considered. From the data calculation, it can be shown that corrosion prediction software can predict corrosion rate in HPHT conditions.

Abstract

Video streaming is digital data that is shared over the internet network. Streaming video through security protection techniques creates a security that is expected to protect intellectual property rights because there is data transfer through the internet. The use of password-based and token-based authentication is a security technology widely used in exchanging data and information between the client and server. However, this method is currently not sufficient to represent a security system using a Geographic Information System. Geolocation is a system or designation of geographic location in a world on an object that is connected via the internet network. IP geolocation can be used to define a particular IP address based on the geographic location from which the device is connected to the internet. The benefit of applying this technology is that each individual or organization can identify the location of a device connected to the internet. The study will use applied research and quantitative data with the implementation of a Geographic Information System that includes the creation of a security architecture on video streaming using Geolocation and test variables that can be used as a basis for analysis to describe the results of the testers. The test results with a random access server system from 50 countries with a blacklist and whitelist grouping mapping system show a success rate of 80%. Based on the results obtained from the use of live streaming security with Geolocation, it can be implemented to improve the security system.

Abstract

This study aimed to decompose lignin from oil palm midrib (OPF) bonds using the fungus Pleurotus ostreatus with various substrates (corn and rice husk). Lignin and cellulose levels before and after mushroom culture were tested by the Chesson-Datta method. Substrate variation with corn and husk rice showed that the addition of corn did not play a role in lignin decomposition. After being given treatment, the best degradation was using 0.6 grams of rice bran and 0.4 grams of CaCO3, 22.01% for lignin and 32.74% for cellulose.

Abstract

One of the problems in archipelagic countries is the land transportation system that has not been integrated between islands. In a relatively wide strait and with a high level of depth, it is impossible to build a bridge. In this case, a submerged floating tunnel bridge/SFTB would be an effective choice. SFTB is an underwater tunnel transport route submerged between the seabed and the surface. Known as the "Archimedes Bridge", the basic principle is balancing buoyancy and tension in the mooring cables. Previous studies on SFTB are still in the form of theoretical concepts and ideas. Further research is needed in all relevant sub-topics to actualize the SFTB. This article reviews previous studies, which are grouped into three sub-topics : (1) materials and construction, (2) dynamic analysis, and (3) feasibility/sustainability studies. At the end of this article, a list of research topics that need further study is presented.

Abstract

Airplanes are a mode of transportation that people are interested in because they have a relatively short travel time and long distances. Therefore, aircraft is a means of transportation with a high level of safety. One level of safety comes from the aircraft's Air Conditioning (AC) system, which functions as a temperature controller for the aircraft during flight and as a pressure protector during flight. Various components make up an aircraft AC system, one of which is the Air Cycle Machine (ACM). Where the ACM changes the temperature to extremes from hot to cold, the ACM becomes fouling, thereby reducing the performance of the ACM itself and causing an increase in the cabin temperature of the aircraft. This problem was solved by a different cleaning method, first using Aluminum Solution and second without using Aluminum Solution. The difference in cleaning methods aims to determine the right cleaning method to overcome the existing problems. The results showed that power without using aluminum solution gave 49.802 kJ/s in 5 minutes and 54.771 kJ/s in 10 minutes, while power using aluminum solution showed 40.1705 kJ/s in 5 minutes and 61.4155 kJ/s in 10 minutes. This indicates that the use of Aluminum solution requires greater power after the ACM rotates for 10 minutes, affecting the efficiency of the ACM itself. The results prove that the cleaning method without aluminum solution gives results of 140.6% at 5 minutes and 90.34% at 10 minutes compared to before.

Abstract

Cavendish banana (Musa acuminata) is one of the most important fruits in the world. Cavendish shoots tissue culture using bubble column bioreactor can be a solution to produce high yielding plantlet and gallic acid due to the aeration with minimum shear stress. In this study, the average growth rate, presence of gallic acid, and antioxidant activity (IC50) in the bubble column bioreactor (200 mL capacity) with the aeration rates of 1 mL/s and 2 mL/s using Murashige & Skoog half-strength liquid medium supplemented with 0.5 ppm gibberellic acid will be analyzed. The aeration system used was atmospheric air. The leaves and stems were extracted by maceration using 96% ethanol solvent (1:10 (w/v)). A qualitative phenolic test with FeCl3, thin layer chromatography, and antioxidant test with 2,2-diphenyl-1-picrylhydrazyl was carried out. The average growth rate in the bioreactor were 0.22 ± 0.001 g/day (1 mL/s) and 0.21 ± 0.001 g/day (2 mL/s). All the leaf and stem extracts showed positive results for the phenolic test, but the presence of gallic acid could not be detected clearly by thin-layer chromatography. The IC50 values in aeration rates of 1 mL/s and 2 mL/s of the leaves were 41.35 and 79.54 μg/mL, respectively, while the stems were 51.87 and 104.94 μg/mL, respectively. It could be concluded that the growth of the banana plantlet and the production of antioxidants in the bubble column bioreactor was higher in aeration rate of 1 mL/s than 2 mL/s.
