Specific Gravity Analysis of Onion Peel and Snail Shell Particulates as Composite Fillers in Ship Applications Sunday Ayoola Oke
International Journal of Marine Engineering Innovation and Research Vol 6, No 2 (2021)
Publisher : Institut Teknologi Sepuluh Nopember

There is limited knowledge on the specific gravity of agro-based fillers, particularly particulate onion peels and snail shells despite their potentials as the ship's hull composite materials. This work reports experimental results on specific gravity concerning particulate onion peels and snail shells as fillers in ship's hull composite fabrication. Specific gravity bottles, water, and 15g each of particulate onion peels, snail shells, and their mixtures were used in laboratory conditions. It was found that onion peel particulates (specific gravity of 1.09± 0.41 for 0.063 mm), snail shell particulates (specific gravity of 0.95 ± 0.01 for 0.063 mm), and mixtures of particulate onion peel and snail shell (specific gravity of 1.02 ± 0.08 for 0.150 mm, 10g particulate onion peels + 5g particulate snail shell) yielded the least values, requiring the least fuel expenditure in generating torque for the desired motions during the ship's voyage. Moreover, a policy to use the snail shell recommendation should be formulated as it is the overall best to help in cost reduction by shipping organizations. Previous studies were on tomatoes and potatoes, among others. However, the present study takes a new direction to innovatively consider hardly studied fillers for polymer composites for the first time.

Fuel accounts for the majority of the ship's operating costs. Increased propeller efficiency can help to reduce fuel usage. The higher the efficiency, the less energy is wasted. Ships with high propeller efficiency may be able to provide more thrust while using less fuel. Propeller Boss Cap Fin (PBCF) installation is one of the solutions for improving propeller efficiency that is ideal for a submarine. PBCF may lower the submarine's energy usage, allowing it to recharge its batteries less frequently. According to certain studies, PBCF can boost propeller efficiency by 7% while lowering noise levels by nearly 6 decibels (dB). The impact of PBCF phase lag variation on skewed propeller performance and flow will be the subject of this article. CFD simulation using phase lags of 0, 12.86, 25.72, and 38.58 will be used in the study. The simulation shows that PBCF can improve propeller efficiency while lowering propeller torque. Even though all phase lag modifications show a reduction in propeller thrust. On its hub vortex, they also reveal the existence of distraction.

Cavitation Analysis of Kaplan-Series Propeller: Effect of Pitch Ratio and nProp using CFD Mohammad Danil Arifin; Frengki Mohamad Felayati

Publisher : Institut Teknologi Sepuluh Nopember

Cavitation is defined as a phenomenon or action of the traveling bubbles that pass through the hydrofoil in which the reduction of pressure below the liquid’s vapor pressure leads to the formation of small vapor bubbles (or cavities) caused by the dynamic pressure of the propeller blades. It caused some effects on the propeller of the ship i.e. it can greatly reduce a ship’s propelling efficiency, damaged propeller material or blade erosion, vibration, and disturbance noises. Cavitation can be minimized by proper attention regarding the design of the propellers and variation of propeller variables parameters. For that reason, this research conducts a cavitation analysis on the Kaplan-Series of the CPP by varying P/Db=0.4, P/Db=0.6, and P/Db=0.8; also the rotational speed of the propeller (nProp) i.e. 125 rpm, 175 rpm and, 225 rpm. The numerical analysis was made based on the Computational Fluid Dynamic Method (CFD) to calculate the pressure ratio (ΔP) and percentages of the cavitation area (Rs) due to a configuration of the propellers parameter. The simulation consists of the 3 steps; pre-processor, solver manager, and post-processor. The result shows that the value of the pressure ratio increased significantly at the higher P/Db and nProp. Also, the variation of P/Db and nProp has a significant effect on the development of Rs (%) at the higher P/Db and nProp.

Investigating the Motions Behavior of a Ferry in Waves Caused by Damaged Conditions Suandar Baso
International Journal of Marine Engineering Innovation and Research Vol 6, No 2 (2021)
Publisher : Institut Teknologi Sepuluh Nopember

A progressive flooding-ingress of water to a compartment of a damaged ship affects the motions of a ship. In this present study, the behavior of the motion of a ferry caused by damaged conditions in waves was investigated through the experimental work. The leakage of compartments was made into several scenarios including one, two, and three damaged compartments, and the damaged ship model was simulated in heading and beam waves. The research results show the one damaged compartment on the engine room (ER) affected extreme stern trim as well as Void No.1 affected extreme bow trim. The two damaged compartments on the water ballast tank (WBT) No.2 and Steering gear room (SGR) resulted in extreme stern trim as well as WBT No.1 and Void No.1 affected extreme bow trim. The heave, pitch, and roll responses on the damaged Void No.1 are higher comparing with the damaged ER. Also, the heave, pitch, and roll responses on damaged SGR and WTB No.2 are higher than Void No.1 and WBT No.1. The peak resonances of heave RAO on bow trim affect higher magnitude than on stern trim. Pitch or roll RAO caused by the increased bow trim or stern trim in head and beam waves has a small magnitude within the response.

Automatic Monitoring and Controlled Atmosphere System Using Arduino on Tropical Fruit Container Integrated with IoT Alam Baheramsyah; Khitoh Fatahilah

Publisher : Institut Teknologi Sepuluh Nopember

Indonesia is a tropical country that is gifted with various kinds of abundant natural resources. Among them are exotic fruits which are in great demand by other people in the world. Meanwhile, in the delivery and storage process for distribution, technology that can maintain the resilience of the fruit is needed so that it does not ripen quickly, thereby increasing its economic value. From this problem, a device called Controlled Atmosphere Storage (CAS) was created which could store fruit and adjust its room conditions according to the specific air requirements of each commodity in the container. The control system design in this study aims to determine how to regulate the levels of ethylene, oxygen, carbon dioxide, and temperature by using the Arduino Uno as a microcontroller and integrating it with the IoT system. The system consists of a microcontroller, DHT22 sensor, MQ 135 sensor, MQ5 sensor, KE25 sensor, relay, Esp8266, and actuators such as fans and servo. From the experimental results, it is known that the control system used is capable of conducting air conditioning in the container and can integrate it with the IoT concept using Thingspeak.com media.

The application of a dual-fuel engine has massively been used as the main engine. However, in dual-fuel engine operations, problems occur in low-load operations. The combustion quality with unstable combustion conditions and relatively low thermal efficiency. In this research, a gas split injection strategy was implemented on the dual-fuel engine. The purpose of this research is to compare the performance of the engine between dual-fuel operations using gas split injection strategy and single injection. Furthermore, split injection is a fuel injection system by dividing the injection into several injection stages with a certain mass and period. This injection system was applied on a dual-fuel engine system, which was previously a modification of the conventional diesel Yanmar TF 85 MH. The variation in this study is the injection split ratio (ISR) 75-25, variations in injection time, and variations in load with specified engine speed at 2000 RPM. The results obtained in this study are the best variations found in ISR 75-25 gas split injection with injection distance at 260°bTDC & 244°bTDC. Due to the injection distance, a significant difference occurred in all parameters tested between single injection and split injection. The significance of the difference in power, torque, BMEP, SFOC, and the thermal efficiency only occurs at 100% load, which is 4.3%; 4.2%; 4.2%; 16%; 18.3%.
