Abstract

The continuous flow of marine debris in the sea has been a problem until now. Previous research on garbage collection vessels was conducted in calm water conditions, without waves and waves due to wind. This is different from the real conditions in the sea which are choppy and bumpy. In addition, research on the effect of wave length and amplitude on marine debris collection on garbage collection vessels does not yet exist. This study aims to determine the effect of wave length and amplitude on velocity contours, flow patterns, and ship resistance. The ship uses a circular hollow wing conveyor. Modelling using Rhinocheros software, then numerical simulation using Computational Fluid Dynamic (CFD). Verification of the simulation process uses grid independent by varying the mesh size, then validation of the results is done by comparing with previous experimental research. The results show that the best velocity contour in front of the conveyor is at a ship speed of 1.028 m/s (2 knots) using an amplitude of 0.5 T and a wavelength of 0.5 L. The velocity value in front of the conveyor is 1.551 m/s. This affects the speed of collecting marine debris. This affects the speed of collecting marine debris. The model that has a laminar flow pattern at the bow and at the stern is a speed of 1 knot at an amplitude variation of 0.1 T and a wavelength of 0.1 L. This is the best because it is easy to collect garbage. The smallest drag is the speed of 0.514 m/s (1 knot) at amplitude variation of 0.1 T and wavelength of 0.1 L. At this condition, the fuel consumption is the least. Thus, the greater the wavelength and amplitude of the waves the greater the drag and the smaller the speed.

Abstract

Polluted estuaries can result in oxygen depletion, accumulation of toxic substances and heavy metals, and become a source of pathogens that are threaten for cultivated aquatic biota and coastal tourists. This research aims to analyze 1) pollution index; 2) status of water pollution in Bangka Jaya and Tanoh Anoe Regencies; and 3) testing the level of effectiveness of Layered Filtered Treatment (LFT) using analysis of removal efficiency and degradation capacity on water quality. LTF is a filtration media that composed of coconut husk, membrane and coffee grounds made into briquettes, LFT used to filter polluted estuary waters. The pollution parameters analyzed at Bangka Jaya were nitrate, phosphate, Escherichia coli bacteria and ammonia, while the pollution parameters at Tanoh Anoe were heavy metals Pb and Cd. The research results showed that the pollution status of Bangka Jaya estuary (A1) and Bangka Jaya coastal waters (A2) are moderately polluted, with indices at stations A1, A2 and A3 respectively is 9.19; 8.42; and 8.42. Meanwhile, the water pollution status in Tanoh Anoe estuary are heavily polluted (station B1) and moderately polluted (station B2) with the pollution index at each station being 14.07 and 9.36. The conclusion of this research is that LFT has not been proven capable of removing and degrading the pollutant parameters nitrate, phosphate, E.coli bacteria and ammonia, however the LFT method has been proven capable of increasing dissolved oxygen, stabilizing sea acid, temperature and also water salinity. LFT has also been proven to be able to prevent ocean acidification with a degradation capacity percentage of 6.60%.

Abstract

As an archipelagic country, Indonesia has abundant natural resources and the potential to develop various industries. In this case, the Ministry of Industry still relies on Java as a location to encourage industrial activities in Indonesia. One of the largest industrial areas in Indonesia is located in the western area of Java Island, namely in the Pulogadung, Karawang, and Bekasi areas. Geographically, Indonesia, an archipelagic country, has good inter-island connectivity. The maritime transportation sector is a strategic component forming the national transportation system. Apart from that, the competitiveness of Indonesian commodities, goods, and services is developed due to national logistics prices, which are partly determined by transportation costs. The many commodities produced on Java Island have resulted in a high demand for goods from Java Island. The cost of shipping goods plays a significant role in the buyer's price. In this research, several options were analyzed for sending goods from Java to Sumatera, namely by using a truck and then crossing by ship from Merak Port to Bakauheni Port or sending by ship to Panjang Port, from Tanjung Priok Port or Ciwandan Port. This research was conducted to select a mode of transportation with a minimum unit cost to support delivery activities. Then, this research was carried out using an optimization method to make the shipping costs incurred more optimal. The results of this research will provide an analysis of the efficiency of intermodal transportation in transporting goods on the Java-Sumatera route.

Abstract

Fishermen are a group of people whose livelihood is very dependent on the condition of the marine ecosystem. Ecological damage in their waters caused by the impact of climate variability and illegal fishing activities causes their livelihoods to be threatened. This research uses a mixed research approach, namely quantitative and qualitative. Quantitative data was obtained through surveys of respondents with the help of questionnaires while qualitative data was obtained through in-depth interviews. The research found that lift net fishing households were in a vulnerable condition with a value of +0.23. This research also reveals that fishing households implement natural resource-based and non-natural resource-based livelihood strategies. These efforts are made so that fishermen can live and exist in society.

Abstract

Currently most of the marine fishing in Indonesia uses traditional boats with navigation systems using compasses and mobile phones. Besides being ineffective, this fishing system also has a high risk, so a safer fishing system is needed, namely using an autonomous boat with a system capable of attracting fish. The use of the Autonomous Surface Vehicle (ASV) for monitoring and fishing purposes has been carried out by Aryusmal (2018) [1] , namely using GPS equipped with an Arduino Uno microcontroller to carry out ship movements, and an error of 1.5 m was obtained. Whereas Permana (2018) [2] made an ASV ship with GPS equipped with an APM microcontroller and Arduino Uno, an error of 30 cm was obtained. Referring to the need for a safe fish system and the results of previous research, this paper designed an autonomous ship with a GPS navigation system using a pixhawk microcontroller which is supported by the use of a brushless motor as the main propulsion of the ship and mission planner software to determine navigation waypoints. This system is able to monitor in real time and save the results of navigation and compass movements up to the last waypoint on the Pixhawk microcontroller. To find out the performance of the ASV, waypoint latitude and longitude tests were carried out on a laboratory and field scale. Laboratory test results have an error of 1.7%, while the results of field testing error errors that occur are 4.4% at longitude and the smallest error is 1.3% at latitude. This error occurred due to field conditions due to sea water shocks. However, this error did not really affect the movement of the ASV ship, because the shift was not too far.

Abstract

Palm oil shells are an example of the residual products of the palm oil processing industry which can be utilized as a new alternative renewable energy source in the form of briquettes. The oil palm shells in this study were first carbonized for 1 hour with a heating temperature in the muffle furnace of 600˚C, then crushed and mashed, then kneaded with each variation of adhesive and molded so that the dough can form a cylinder with a diameter of 2 cm and 4 cm high. The average calorific value obtained for cornstarch adhesive, rice flour adhesive and pine resin adhesive were respectively 6634.29 cal/gr, 6702.47 cal/gr, and 7798.31 cal/gr. The average water content in cornstarch adhesive, rice flour adhesive, and pine resin adhesive were 5.1%, 5.0% and 3.7%, respectively. The average values of volatile matter content in the adhesives of cornstarch, rice flour, and pine resin were 30.90%, 31.70% and 60.73%, respectively. The results of this study indicate that any increase in the calorific value will be followed by a decrease in the water content and the varying values of the volatile matter content.

Abstract

Centrifugal pumps are the most commonly utilized in industries, agriculture, and households. In the microbubble generator, the centrifugal pump is driven by a DC motor for efficiency. This research was conducted to determine the optimal centrifugal pump design for microbubble generators using 3D-printed PLA material. The pump drive uses a brushless DC motor. With impeller dimensions r1=16mm, r2=26mm, β1=46.8, β2=62.8, and number of blades = 8, the resulting head is 2m at a constant operational current of 3A and a flowrate of 0 L/m. The same operational current input yields a maximum flow rate of 14 L/min with a head of 0.5 m. Maximum head exists when there is no liquid on the outlet side. At current ≥ 6.5A, there is a deviation from the previously formed trend. The input power of 58W is generated when the maximum flow rate is 25L/m. Maximum efficiency can be achieved as the input current increases to ≤6.5A and 18L/m. At conditions ≥6.5A, efficiency decreases drastically as the input current increases. This centrifugal pump design can work optimally at a constant input current of 6.5A with an input power 58W for the microbubble generator.

Abstract

Improving the airfoil aerodynamics is quite an essential aspect of the aviation industry. One method for improving airfoil aerodynamics involves applying passive flow control techniques. The effect of using the gurney flap as passive flow control was explored through the CFD approach with the RANS control equation and incorporating k-epsilon as a turbulence model. The airfoil model utilized in this study was the NACA 0015 airfoil operating at a Reynolds number of 1×106. This study explored three different mounting angles of the gurney flap, namely 45°, 60°, and 90°. The outcomes show that adding the gurney flap has positive results in increasing the lift and drag of the NACA 0015. An airfoil with a mounting angle flap of 45° has an average percentage increase in Cl of 23%, followed by a mounting angle flap of 60°, which is 28%, and a percentage Cl of 45% for a mounting angle flap of 90°. Meanwhile, Gurney flaps with a mounting angle of 45° can increase Cd by an average percentage of 3%, while mounting angle flap at 60° increases the Cd percentage by 4% and 5% for a mounting angle of 90°. Moreover, fluid flow visualization with pressure and velocity contours was given at AoA 10º to determine its effect on increasing lift and drag on the NACA 0015 airfoil.
