Published: January 2024

Background: Cardiovascular system diseases are a leading cause of death globally. Heart surgeries, performed worldwide to treat these conditions, are often followed by high rates of postoperative complications.
Objective: The study aimed to compare the effects of pulmonary physiotherapy on respiratory dysfunction following cardiac surgery.
Methods: Forty patients with pulmonary dysfunction post-coronary artery bypass grafting (CABG) participated in the study. They were randomly assigned to receive either postoperative pulmonary physical therapy, including breathing exercises and respiratory muscle training, or conventional physical therapy exercises. Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and inspiratory capacity (IC) were measured using spirometry. Data analysis was conducted using the Statistical Package for the Social Sciences (SPSS), with paired t-tests comparing all variables. Results were considered significant at a p-value < 0.05.
Results: The study included 21 participants in each group, with a mean age of 55.37 ± 8.72 years. Mean vital capacity in Group A was 2.40 ± 0.46 pre-treatment, increasing to 2.97 ± 0.43, while in Group B it was 2.34 ± 0.41 at baseline, increasing to 2.98 ± 0.36, with a p-value > 0.05 indicating no significant pre- and post-test effects in Group A. Significant pre-post differences in spirometry values were observed within both groups, but no significant differences were noted when compared across the groups following CABG.
Conclusion: The study concluded that pulmonary rehabilitation post-cardiac surgery is highly recommended to minimize postoperative complications of heart surgery. It contributes significantly to the prognosis of these patients, emphasizing the importance of preoperative procedures focused on preventing pulmonary system complications and facilitating recovery in the postoperative period after major cardiac surgeries.

Published: January 2024

Background: Acute decompensated heart failure (ADHF) remains a leading cause of hospitalization with significant morbidity and mortality. Hypoalbuminemia has been identified as a potential prognostic factor in various medical conditions, including heart failure. Understanding its association with in-hospital mortality in ADHF patients could enhance risk assessment and management strategies.
Objective: This study aimed to investigate the association of hypoalbuminemia with in-hospital mortality in patients admitted with ADHF.
Methods: This was a retrospective observational study conducted at a tertiary cardiac care center in Rawalpindi between July and November 2023. A total of 480 patients with a confirmed diagnosis of ADHF were included. Inclusion criteria were age ≥ 18 years, confirmed ADHF diagnosis, and available serum albumin levels upon admission. Exclusion criteria included incomplete medical records, end-stage renal disease, active malignancies, acute liver disease, and acute infectious diseases. Data on demographics, clinical characteristics, and serum albumin levels were collected. Logistic regression analysis was used to assess the association between hypoalbuminemia (defined as serum albumin <3.0 g/dL) and in-hospital mortality, adjusting for confounders like age, sex, and comorbidities.
Results: The cohort comprised 60% males and 40% females, with a mean age of 68 years. Hypertension (78%), diabetes (42%), and chronic kidney disease (36%) were the most prevalent comorbidities. The mean serum albumin level was 3.2 g/dL (SD = 0.4). Hypoalbuminemia was observed in 42% of patients. In-hospital mortality was 15%. Patients with hypoalbuminemia had a 2.5-fold increased risk of in-hospital mortality (unadjusted HR = 2.5, p < 0.001). The adjusted HR was 2.0 (p < 0.01), indicating hypoalbuminemia as an independent predictor of in-hospital mortality.
Conclusion: Hypoalbuminemia is significantly associated with increased in-hospital mortality in patients with ADHF, serving as an independent prognostic indicator. This finding highlights the importance of serum albumin in the risk assessment and management of ADHF patients.

Background: Urinary tract infections (UTIs) are a significant pediatric health concern, often linked to anatomical anomalies of the urinary tract. Understanding the prevalence and characteristics of these anomalies in children with UTIs is crucial for effective diagnosis and management.
Objective: This study aimed to investigate the prevalence and nature of anatomical anomalies in children diagnosed with UTIs, focusing on age and gender distribution, and to identify common anomalies associated with UTIs in pediatric patients.
Methods: A retrospective cross-sectional study was conducted at the Children's Medical Center in Tehran, from March to September 2022. The study included pediatric patients admitted with UTIs, excluding those over 18 years of age. Convenience sampling was used to target at least 70 patients with definitive anatomical anomalies. Data collection involved reviewing medical records and laboratory results, focusing on variables such as age, sex, paraclinical tests, and types of anatomical anomalies. Statistical analysis was performed using SPSS software version 25, employing Fisher’s exact or χ2 tests for categorical variables, and the student’s t-test, ANOVA, and Chi-Square tests for continuous variables.
Results: The average age of patients was 29.61 months (SD = 35.28), with a median of 12.50 months (IQR = 36). The average number of UTI episodes was 3.43 (SD = 2.31), ranging from 1 to 10 episodes. Bilateral hydronephrosis was observed in 15 patients (21.7%), while neurogenic bladder and Reflux Grade 4 or 5 were identified in 11 (15.9%) and 14 (20.3%) patients, respectively. VCUG was performed in 63 patients (91.3%). Unilateral hydronephrosis was the most common imaging finding, observed in 33 patients (47.8%).
Conclusion: The study concludes that children around 29 months of age, particularly females, are more prone to have anatomical anomalies associated with UTIs. Bilateral hydronephrosis was a prevalent anomaly. However, limitations such as potential data unavailability or misinterpretation, errors in laboratory data, and patient comorbidities must be considered when interpreting these findings.

Published: January 2024

In the Surabaya City Spatial Plan for 2014-2030, the Kenjeran Beach area which is included in the Tambak Wedi is a marine tourism area. In recent years, the condition of the Kenjeran Beach area has experienced a decline in tourists. Given that, for several years there have been no significant changes in the development of the Kenjeran Beach area. For Kenjeran tourism to be more optimally developed, it is necessary to integrate and integrate many objects and tourist attractions in one area. The method used is the descriptive qualitative method. The results of the study describe the potential of the Kenjeran coastal area and then several policies that have been carried out by the government to develop the Kenjeran coastal area along with several impacts or conflicts on the local community. The cable car development policy for Kenjeran coastal tourism is very beneficial for the lives of coastal communities in the tourism sector and the economic life of the local community. However, the development only knocked down three fishing posts, which disturbed the people who had previously supported them. Although in the end the three posts were rebuilt in making policies, it is necessary to pay attention to no more losses on the one hand. Furthermore, the Bulak Fish Center policy whose impact is very beneficial for the survival of the Kenjeran coastal community because it is a form of livelihood so economic growth is very rapid. There are still many efforts that can be made for the implementation of policies on the Kenjeran coastal area to be more developed, but in that case, it needs to be analyzed again so that the policy is implemented properly.

Ship construction generally consists of two main parts: the hull and the superstructure or deck house. Several factors must be considered in the construction of a ship. Planning the characteristics of the ship's hull, we are also planning the strength and structure of the ship itself. Midship construction is a construction that must have serious attention in calculating the ship structure. In this section, many forces are acting so that there is a relatively large risk of structural failure. One of the world's classification institutions is BKI, which provides rules for selecting structural profiles. Based on these rules, the load on ship sides is 71,284 KN/m2. Load on the ship bottom is 76,795 KN/m2, Deck Load on Deck Superstructures is 32,581 KN/m2, Load on Cargo Deck is 57,330 KN/m2, Load on Inner Bottom is 68,212 KN/m2, Load on Accommodation Decks is 3,981 KN/ m2.

Authors: Yusim Adi Kurniawan , Hasrianti Besse
Published: January 2024

The waves are quite large, and the ship's movement continues to be a barrier tossed about or up and down on the high seas. It can result in symptoms of illness or an uncomfortable atmosphere for passengers on board. This symptom is often referred to as seasickness or motion sickness. The main cause of seasickness is the absence of similarity of excitability or conformity between the stimulus, eye and ear labyrinth the human brain receives. Usually, people who get seasick are on closed decks because their eyes cannot see any movement. At the same time, the ear labyrinth responds to the ship's movement so that there is a conflict between the stimuli received by the eyes and the ear labyrinth, which is responsible for body balance, causing nausea. In severe cases, passengers or crew must be taken to the hospital. Modelling MSI on Finite Element Method Software, it can be seen that passengers experience ship sickness or, in this case, experience MSI at what time on a cruise on the Cilacap sea lane processed to determine the condition of the ship's MSI to passengers by the acquisition of 6 degrees of freedom where various components that affect such as wind, the main current is a wave it occurs 6 degrees of freedom, i.e. Surging is a translational movement along the X axis, Rolling is the movement of the ship around the X axis, Swaying is the translational movement of the ship that occurs when the ship moves along the Y axis, Pitching is the movement of the ship around the Y axis, Heaving is the movement of the ship along the Z axis. A ship with a speed of 12.5 knots sailing in the Cilacap sea with a wave height reaching an average wave of 2.5 meters, the MSI of the ship occurs, namely the effect of sea conditions on the movement of the ship indicating that the ship's response to the sea is at 90 degrees. In the opposite direction of the wave, MSI occurs in 20% of passengers after 2 hours on the vehicle deck at the bow point. At that time, the magnitude of the encounter frequency was 2.137 Hz.

Authors: Umar Hasdinar
Published: January 2024

The Sunda Strait has a significant enough fishery potential in Indonesia. Fish catches from the Sunda Strait are landed in Pandeglang Regency, one of which is at the Labuan Coastal Fishing Port. The types of fish that are targeted for catching are mackerel and tuna. The high selling price of fish causes fishing operations to continue to be improved. Fishing operations that continue to increase can lead to a scarcity of fishery resources. Therefore, it is necessary to study the rate of fish resource utilization to determine their status. This study aimed to evaluate the rate of exploitation of tuna in the Sunda Strait based on fish catch data on 30 GT vessels and analyze it using policies issued by the Indonesian government. In this study, a simple linear regression method was used. Result of analysis, in 2025, the fish stock is only 21,682 ton, while the number of fish taken is 66,497 ton, which means that in 2025 there will be no more fish because the fish stock has run out and cannot meet the number of fish that needs to be taken.

Seakeeping is the ship's ability to stay afloat on the waves. The ship's maneuverability is greatly influenced by external factors related to the state of the sea and the waters in which the ship sails. Calculating seakeeping with various variations of depth, current, and wave height is needed for ship safety when sailing in the calculation of seakeeping using linear strip theory to calculate the response of heaving and pitching movements while roll damping theory for rolling movements. In this study, the ship's motion is calculated using the Finite element method software Hydrodynamic Diffraction and Hydrodynamic Time Response. For variations in wave height and water depth, referring to the conditions of Indonesian waters, from the reference, variations in wave height of 3 m, and 5 m (based on sea state WMO). In contrast, the current variation uses a current with a speed of 10 knots and a current depth of 10 T, 15 T, and 20 T. Based on the data obtained in data processing, it can be seen that the high value of the wave frequency obtained at 90 and 270 degrees wave direction is relatively high. The value of the roll spectrum in the direction of 0 and 270 degrees is large and can cause rolling on the ship. In the direction of 0 and 270 degrees, the wave resistance can be reduced by th Lobsters are animals that enter into crustaceans that have problematic skin. Adult lobsters can generally be found on a stretch of sand with coral spots with a depth of between 5-100 meters. This condition will cause a low number of young lobsters in the waters. This research was conducted with a case study regarding the policy of opening lobster seed export, which aims to find out how the policy is to open the export of lobster seed. The data obtained is done by reviewing the literature on the internet. Based on the analysis, the export profit of lobster seeds has continued to increase every month since it was again allowed by the government in May 2020. Based on data from the Central Statistics Agency (BPS), lobster seeds began to be re-exported in June 2020 at 32 kilograms, costing the US $ 112,990. The government can help with training and outreach on lobster cultivation. The government can offer Lobster a partnership package to help people start a freshwater crayfish business.

Published: January 2024

A General Cargo Ship is a ship that carries various kinds of cargo in the form of goods. The goods transported are usually packaged goods. Using a bulbous bow on the ship's bow is the best alternative. Bulbous bows are installed on ships with high speed to reduce drag, whose nature depends on the function of the block coefficient and Froude number of ships. Ships with particular Cb and Fn can use a Bulbous bow due to considering the advantages of a significant enough resistance reduction, or vice versa. This research is a general cargo ship model with a bulbous bow. They are using the main dimensions of the ship with Length Over All (LOA) 153.45 m, Length Between Perpendicular (LBP) 144.2 m, Length On Load Waterline (LWL) 147.8 m, and Breadth (B) 25.27 m. height (H) 13.5 m, Draft (T) 9.52 m, Speed ​​(V) 14.75 Knots.

Published: January 2024

Ship motion is the ability of a ship to survive at sea under any conditions. Therefore this capability is an essential aspect in terms of ship design. The shape of the hull dramatically influences the characteristics of the movement and operability of the ship itself. Vessel operability is the time at sea when the structure can still operate according to the established criteria and its correlation to the wave height where the requirements will be exceeded. In this study, an analysis of 3 degrees of freedom of translational movement and rotation of heave roll and pitch was carried out on the planing hull type fast boat model at regular waves with the parameters of body mass, gyration radius, damping, and others presented in the form of a Response Amplitude Operator (RAO) graphic image.

Authors: Alamsyah Alamsyah
Published: January 2024

A tugboat is a ship that guides large ships to dock, helps escort coal barges over bridges and also helps carry out rescues if needed. Some Tugboats had to experience increased engine power because they followed ministerial regulations. When in operation, the tugboat's engine generates the power necessary to move the ship, but on the other hand the engine also produces vibrations. Vibrations that occur on the ship have a side effect that damages the structural resistance of the ship's own construction. The purpose of this study is to find out the value of vibration and noise that occurs on the deck above the engine room due to increased engine power on the Tugboat. The method used is Finite Element Analysis using Ansys software. The results showed that the excitation frequency of the parent machine based on successive rpms was 14.99 Hz, 16.65 Hz, and 18.32 Hz. Based on the calculation of system amplitude, obtained value ranges of 8.73 x 10-10 to 8.25 x 10-10 for 1 machine and 1.14 x 10-9 to 5.65 x 10-10 for 2 machines. Then the standard vibration value is in the range of values 0.00012 to 0.00017 for 1 engine and 0.000652 to 0.000479 for 2 machines. Furthermore, the noise value obtained is in the range of 140.53 dB to 130.88 dB for 1 engine, and 140.68 to 130.75 for 2 engines. All results from calculations regarding vibration standards on the 2 deck models above the engine room get results according to standards, but the resulting noise value exceeds the limit, so it can be concluded that the construction of the engine room and deck is safe from vibration but has excessive noise.

Published: January 2024

Friction Stir Welding (FSW) is a solid-state welding technique that can produce high-quality joints without defects that commonly occur in liquid welding. However, FSW has limitations in underwater applications due to the friction between the tool and the material that causes a decrease in heat efficiency and shear force. To overcome this problem, this study proposes an underwater welding (UW) system with the FSW method on 316L stainless steel exposed to seawater. This UW-FSW system uses a high-speed rotating tool surrounded by an inert gas shroud to prevent direct contact between the tool and seawater. The aim of this study is to evaluate the performance of this UW-FSW system in terms of mechanical properties, microstructure, and corrosion resistance of 316L stainless steel joints. The results of this study show that the UW-FSW system can produce joints with better tensile strength, hardness, and corrosion resistance than conventional FSW. This is due to the rapid cooling, reduction of oxidation, and formation of a thicker passive layer on the joint surface. This study provides a contribution to the development of environmentally friendly and efficient underwater welding technology.

Abstract: Plates are a very important part of shipbuilding and offshore structures. The reinforced plate is used to withstand loads acting in the axial and bending directions. The structure of the deck or bottom plate exhibits buckling or yielding behavior. Thus, it is very important to analyze the ultimate bearing capacity of a plate structure subjected to compressive loads for safe ship structure design. The material configuration used is the most important aspect in the FPSO structure design criteria. Plates and stiffened plates experience local buckling due to the external load when the hull girder collapsed. The objective of the present study is to analyze the effect of flange and web thickness to the ultimate strength on the FPSO in terms of plate deformation located of the bottom and deck area under compression stages. In this study, the attached plate thickness is varied according to FPSO data and BKI Rule. The stiffened plates element located at the bottom and deck area are modelled by Tee-Bar and Angle-Bar element. The simply supported condition is applied to the model and the anon-liniear Finite Element Method is used for the analysis. The result obtained by NLFEM shows that under tension and compression, the stiffened plate of Tee-Bar model, the deformations are 1,75 mm and 1,8 mm respectively. While for Angle-Bar model the deformation are 12,4 mm and 13 mm under compressing respectively.

Abstract: The Port Singapore Authority (PSA) have a big role in sea transportation in Indonesia, whoever average 50 big vessels per day are tendered at the wharf of Singapore port for loading and unloading thousands of containers, so if Singapore port is congested for several hours the impact will make the crowded of sailing schedule for many vessels. Last week suddenly without any announcement Singapore port reported a problem with their port facilities and so their system, therefore many vessels were anchorages for several days about 4-6 days at the outer of the port for waiting time to tender. This accident makes the sea transport system by feeder service Indonesia-Singapore and vice versa re-scheduled. The impact for export-import activities from and to Indonesia was trouble because many can't call on time even omitted.  For several years or starting in 1985 Indonesian Shipping lines depend on Singapore port as an international hub port that will through cargoes to the destination port. They chose Singapore port because there are complete port facilities and a container system, nobody knows that crisis so will bome at Singapore as the biggest port in South East Asia. So now suggested to all of Indonesian shipping and Government to make a new big port as functions like Singapore port as an International hub port.

The changes in consuption patterns triggered by the Israeli-Palestinian conflict and the pro-Israel boycott movement in Indonesia are important since they show the influence of socio-religious values on cunsumers behavior and the resulting impacts on companies and the workforce. Previous studies primarily focused on analyzing the causes and implications of the conflict, and paid insufficient attention to the socio-religious behavior perspective in changing consumption patterns. This study includes boycott actions, the social and religious characteristics of both pro and con movements, and the involvement of state institutions in responding to the Israeli-Palestinian conflict. The desk research method is used by collecting data through digital media analysis, including online news, social media, and library research. The findings of this study include the internalization of social religious values as a driving force for boycott actions, moral considerations influencing the defense of opinions in society, and the involvement of major powers in strenghtening the boycott movement. The uniqueness of this study lies in its in-depth approach to religious social behavior in the context of changing consumption patterns amidst armed conflict.

Problem-Based Learning Strategies As The Main Concept of Quality Learning
Authors: Jannah Nur
Published: January 2024

One of the current learning problems is the lack of educators in mastering strategies or learning models that lead to the quality of the learning output itself. The application of methods in learning is one of the keys to achieving quality learning because, in its implementation, the strategy will determine whether the teaching is effective or not. Problem Based Learning (PBL) strategy is one of the strategies considered important in achieving the quality of education because it is based on social and scientific problems by the tendencies of the learner, resulting in a contextual and scientific understanding. In this learning model, students are invited to solve some issues and find solutions for the contextual problems. Thus, students can be actively involved in the learning process so that learning does not feel monotonous and only listens to the teacher lecturing. This strategy indirectly also fosters students' ability to analyze problem-solving and think critically about solving problems or events they will face. This paper examines the concept of quality learning problem-based learning in the idea of quality, both absolute and relative, as Edward Sallis argues. So that learning does not feel monotonous and only listen to the teacher lecturing.
