Abstract

The breakwater armored with 15 T Dolos block had destroyed several times during constructing even the section verified by experiment study in wave flume, and it was destroyed again after the repair design and test verification. The damage phenomena were compared between on site and in the lab. In the third model test study, it proposed the problems of rod broken caused by block shaking and rolling impact, as well as overall sliding caused by small block supporting the big block. The stability of the repair plan was verified again by increasing the block weight, and the section was verified under the wave impact after on-site implementation. The study also revealed the fact that shaking led to the broken of the rod and the breakwater failure.

Abstract

Towing hook is one of the important components of a tugboat. Its function is to tow various types of ships, namely containers, tanker ships, and even barges. This activity affects the components to undergo failure and crack, especially the support structure of the hook. Earlier research has analyzed various types of stress characteristics, namely fatigue crack, maximum stress, and maximum factor of safety aimed both at the support structure and the whole profile of the tug. The research aim is to determine the value of stress in the support structure and the safety factor brought by tensile load transferred from the towing hook. The analysis is done using finite element method in Altair Hyper Works 2019. Structural strength of the towing hook support structure is analyzed in 2 loading conditions, namely lightweight barge and full load barge. Two different approaches are used for comparison. The first approach is using barge resistance, and the second is by utilizing maximum tug horse-power to speed ratio. Maximum stress acquired in both loading conditions and both approaches is 118.64 MPa; 121.80 MPa; 230.90 MPa; 329.86 MPa respectively. The safety factor is measured using 2 criteria, BKI permissible stress criterion and BKI Material Strength criterion. Results of safety factors based on BKI permissible stress are 1.644; 1.601; 0.845; and 0.591. According to BKI Material Strength, the safety factors on both loading conditions are 3.371; 3.284; 1.732; and 1.212.

Abstract

Coronavirus belongs to the ARI (Acute Respiratory Infection) disease, which has a high level of mortality risk. In 2019, this virus was transformed into Covid-19 with a rapid spread and a more massive impact. This disease has become a worldwide pandemic. Indonesia is a developing country and is included as one of the most densely populated countries affected by the Covid-19 pandemic, which has great potential to fail in overcoming this problem. Approximately 60% of Indonesia's population lives in coastal areas with low levels of welfare in almost all sectors of life such as social, economic, education, and health. This study aims to analyze the level of community vulnerability in the coastal area of Surabaya City by using the Analytical Hierarchy Process method. From the data taken by the survey, the results of the exposure of the Bulak Banteng Village area of Surabaya in the health, socio-cultural, economic, and general fields are 0.0469, 0.0871, 0.1809, and 0.3551, respectively. So the overall vulnerability is 0.67, which is included in the medium vulnerability criteria.

Abstract

Wooden ships use jati wood. Over time jati wood has become scarce. So that jati wood is relatively expensive. therefore bamboo is researched starting from the skin, bamboo meat, and bamboo internodes contained in the plant. In the structure of bamboo there are internodes. The bamboo segment is the weakness of the bamboo structure. The effect of bamboo segments in composite construction was investigated. Sesame oil replaces mineral oil and chemicals, because sesame oil is biodegradable, non-toxic, environmentally friendly, and renewable. To determine the effect of bamboo segments, tensile and bending tests will be conducted on the bamboo composite. The results of this research are expected to find alternative materials, namely bamboo fibre-based composites or so-called bamboo reinforcement plastics (BRP) as materials for making people's ships. This study found that the more layers of bamboo and bamboo segments are very influential in influencing the tensile and bending strength of a laminated material. The tensile testing value of layer 3 with segments reached 127.556 Mpa and without segments 933.333 as well as bending testing layer 3 with segments reached 113.889 Mpa and without segments 111.111 Mpa. From this value, the value has not met the standard of the Indonesian Classification Bureau (BKI).

Abstract

ASTM A36 steel is a steel commonly used in shipbuilding construction. The property of steel that is highly avoided is susceptible to corrosion or  corrosive which can reduce the strength of the structure. Over time, technology has developed, and methods have been found to inhibit the rapid rate of corrosion, coating process is one of them. The success rate of coating process is also strongly influenced by the surface preparation process. The surface preparation process in this study was by differentiating the size variations of the SG18, SG25, and SG40 steel grit abrasive materials and the spraying pressure of the 5 bar, 6 bar, and 7 bar abrasive materials and the provision of scratch defects on the specimens that had been coated with epoxy primer paint. The purpose of the research conducted was to analyze variations in  size of the abrasive material, the spraying pressure of  the abrasive material, and which combination of variations is the best for specimens  considered to have been scratched. In each variation, the value of the corrosion rate will be  increased when the size of the material increased and the value of the corrosion rate increases when the spraying pressure decreases. The results obtained from this study indicate that the lowest corrosion rate value is 0.0027 mmpy with the outstanding category of the variation used, which is grit SG40 steel abrasive material and at a pressure of 7 bar.

Abstract

The utilization of the Crushing and Barge Loading Conveyor (BLC) systems is important in coal processing. A crushing system is required as a tool for the process of crushing coal into smaller sizes and then transferring it to the stockpile. While a BLC system is needed to transport coal from the stockpile to the barge. In general, the control and supervision systems for crushing and BLC systems are carried out separately by two operators. However, the distance between two operators causes a time lag information. In this research, we create a Supervisory Control and Data Acquisition (SCADA) system with the type of Multiple Programmable Logic Controller (PLC) on the Crushing and BLC systems using Profinet communication integrated by two PLCs with one Human Machine Interface (HMI) and WinCC. The system is equipped with real-time data, automatic control, and online surveillance with smartphones via the S7APP application. The error resulting from the reading of each component by the HMI and smartphone reaches 0%, while for automatic control, the system works very well, having a success rate of 100%.

Abstract

In designing a ship, it is necessary to know the response of the ship's motion before sailing. The purpose of this research is to determine the ship's motion response to waves as well as ship speed in ship loading operational conditions. The method used in this study is the B-spiline mathematical equation and the strip theory method, with the help of ship motion software, which varies the ship's load by 100% DWT, 50% DWT, and 25% DWT. While the highest significant amplitude heave value occurs on a ship with 100% DWT conditions with a speed of 18 knots and a wave direction of 900, which is 2.70 meters, the highest significant value of amplitude pitch occurs on a ship with a condition of 25% DWT with a speed of 6 knots and a wave arrival direction of 1800, namely 1.10 degrees, and the highest significant value of roll amplitude occurs in ships with 25% DWT conditions with speeds of 18 knots with a wave arrival direction of 900, which is 3.42 deg. The research results detected at a speed of 18 knots for the significant amplitude heave value, the significant amplitude pitch value, and the maximum RAO value still meet the Nordforsk criteria.

Abstract

The development of technological science towards the defense of a country is growing rapidly. The country needs increasingly advanced defense technology but is constrained by an increasingly large budget due to dependence on producing countries. The state provides opportunities for technocrats to carry out research that can later create a defense technology that is inexpensive and does not burden the state budget. The artificial S60 57mm cannon is one of the cannons that functions as an air attack deterrent. The operating system of this weapon is still manual. This research will design and prototype an automatic Weapon Control System on the S60 57mm gun. In this development using the Atmega 8 microcontroller is the controller and interface for transferring data from the camera (Optronic) to the servo motor. The result of the camera position (optronics) will be followed in real-time by the gun barrel. In designing a target tracking control system automatically using the proportional control method. The results of testing the ability of the servo motor as a camera driver to follow targets or moving objects with a maximum angular speed of 15.5 degrees/second at a speed of 0.3 seconds, the average frame rate of the camera are 60 fps. c. Based on testing the servo motor using the Atmega8 microcontroller support, the reading of the angle direction of the servo motor is displayed in the Delphi software. Based on the test results, there is a difference between mathematical calculations and measurements using an arc ruler. With mathematical calculations, there is a difference with a value of 1.06 degrees per 1 degree.
