Published: December 2024

Abstract
Multibeam Echo Sounders (MBES) have significantly advanced underwater acoustic data analysis, allowing for the detection of various marine features. The enhanced capabilities of water column acoustic data analysis by MBES have played a crucial role in numerous research projects, including mapping methane gas flux and studying free gas release. This research aims to detect and quantify underwater gas seeps by leveraging the advanced imaging capabilities of MBES. The workflow involved displaying water column data, removing irrelevant echoes, applying amplitude threshold filtering, validating Local Intensity Maxima (LIM) values, exporting final coordinates, and calculating volumes using voxel-based methods. Results showed that higher frequencies (200 and 400 kHz) provided more detailed and accurate gas seep detection at 30 m depth, with average volumes of 25.972 m3 and 31.050 m3, respectively. However, at a depth of 60 m, the 100 kHz frequency was more effective, with an average volume of 28.324 m3. These findings underscore the importance of frequency selection in MBES surveys for accurate gas seep detection and quantification. This study provides valuable insights into underwater gas seeps, enhancing our understanding of their impacts on the marine environment and the global carbon cycle. This study supports SDG 14 by advancing marine ecosystems, including the management of marine resources.

Published: December 2024

Abstract
Lamong Bay Terminal, part of Tanjung Perak Port in Surabaya, functions as a container terminal. The port in the Surabaya area causes high ship traffic activity in the waters of Lamong Bay and sediment may be carried away from rivers heading towards the sea. The sedimentation process in waters can cause problems because it can cause shallowing of the waters, so it is necessary to maintain and monitor the depth of shipping lanes to maintain the safety of sea traffic. Therefore, understanding the hydrodynamics of seawater and sediment movement in the water region is necessary for successful dredging operations and assessing the impact of silt on port areas. In this research, the approach used to determine current patterns and sediment distribution was through the application of a numerical model with three– dimensional baroclinic hydrodynamic equations. The numerical modeling study in this research uses tidal data, sediment samples, salinity, and temperature to determine current patterns and the rate of sediment distribution. This process is carried out periodically and continuously as part of the evaluation of Lamong Bay Terminal. The results can serve as a reference for dredging planning to maintain the depth of the waters at the Lamong Bay Terminal. In this study, the highest current velocity was obtained at the time of spring tide reaching 0.9 ms−1 and at the neap tide of 0.4 ms−1. The sediment distribution pattern in the waters of Lamong Bay affected the existence of the pier and the morphological conditions of the seabed. The largest siltation or sedimentation that has occurred at Lamong Bay Port is 0.055 m/month near the jetty, thus depth monitoring is needed in this area, regularly. This study supports SDG 9 by advancing resilient infrastructure solutions to manage the sedimentation process in waters.

Published: December 2024

Abstract
As an archipelagic country with emerging economies, maritime transportation has significantly contributed to the Indonesian economy by ensuring the fullness of domestic demand for goods and services, accelerating annually. However, with the increase in sea traffic, the probability of collision accidents may also grow, posing non-negligible risks to individuals and society in various aspects. Considering this condition, this paper assesses and evaluates past maritime collision accidents in Indonesia to observe and analyze the tendency of factors contributing to collision accidents. The analysis was conducted using the Fault Tree Analysis (FTA) method, qualitative and quantitative, on data obtained from the collision investigation report in the last 20 years. The qualitative approach is used to propose the minimal cut set, and the quantitative analysis is conducted to estimate the probability. Based on the obtained probability and the produced cut set diagram, the conclusion states that human-related factors contribute to the top even occurrence at most, implying that the human factor is the most contributing factor to collisions. Those factors include the lack of training, lack of experience, and improper decisions.

Published: December 2024

Abstract
This research aims to enhance maritime fuel supply’s efficiency, safety, and sustainability by advocating for the standardization of bunkering systems in ports. Through the application of Multi-Criteria Decision Making (MCDM) and the Analytical Hierarchy Process (AHP), this study assesses three primary bunkering methods: Ship to Ship, Truck to Ship, and Onshore to Ship. The criteria for evaluation encompass safety, economic factors, operational efficiency, technical considerations, and additional relevant aspects. Stakeholder feedback underscores the significance of safety (0.281) and economic (0.274) criteria, eclipsing operational (0.274), technical (0.137), and other factors (0.033) in importance. The findings prominently advocate for the Onshore to Ship method as the superior option for standardization in principal ports, marked by a value of 0.480, with Truck to Ship and Ship to Ship methods trailing in preference. Sensitivity analysis reinforces the stability of this outcome, indicating that adjustments in criteria weightings scarcely affect the overall conclusion, thereby affirming the Onshore to Ship method’s predominance. This method, characterized by a pipeline connecting the jetty to ships, holds considerable potential for both research and practical applications in port logistics.

Published: December 2024

Abstract
The global maritime industry is transitioning towards sustainability to meet stringent environmental standards under IMO’s MARPOL Annex VI and the Paris Agreement. LNG emerges as a promising marine fuel, significantly reducing sulfur oxides (SOx), nitrogen oxides (NOx), and particulate emissions compared to traditional fuels. Indonesia, a major LNG exporter, aims to utilize LNG domestically under its Long-term Strategy for Low Carbon & Climate Resilience 2050. Adopting LNG in Indonesia’s maritime sector faces challenges, especially retrofitting existing diesel engines. Technical hurdles include ensuring engine compatibility, modifying fuel systems, and conducting comprehensive on-board testing due to limited infrastructure. Regulatory frameworks like Biro Klasifikasi Indonesia (BKI) Rules and the NOx Technical Code 2008 amendments provide the guidance for emissions compliance and testing. This paper discusses methodologies to overcome these challenges, emphasizing robust testing protocols and sea trials to validate engine performance and emissions under real-world conditions. Collaboration among stakeholders is essential to facilitate Indonesia’s transition to sustainable maritime practices. Future advancements in LNG technology and infrastructure will bolster Indonesia’s energy security and contribute to global emissions reduction targets in maritime transport.

Abstract
Botanical Garden is an ex-situ plant conservation area with documented plant collections, especially species of scarce, endangered, and endemic species. Bogor Botanical Garden has 25 collection plots, and this research focused on collection plots V (V.A., V.B., and V.C.). The study aims to estimate the percentage of trees in healthy condition and the number and types of trees with severe tree damage. The method used is Forest Health Monitoring (FHM), which was done visually to identify the type and extent of tree damage. The results of the research showed that 234 trees fit into the healthy tree classification (86.67%) with NIK (damage index value) (0 ≤ 5) from the total number of trees observed, namely 270 trees in those collection plots. The tree classification for heavy damage was four trees (1.48%) (NIK 16 ≥ 21), including Barringtonia racemosa (L.) Spreng., located in collection plot V.A.078a, Syzygium aqueum (Burm.f.) Alston., which is in plot V.A.129, and Syzygium polycephaloides (C.B.Rob.) Merr., which is in plot V.B.111 and 111a. Most trees in plot V were healthy, but the least were heavily damaged.

Abstract
Arboretum Kwala Bekala campus II University of North Sumatra is one of the Green Open Spaces that has benefits for education, research, and ecological functions formed into an interconnected system. Development of arboretum management continues to be carried out. One of them complements the tree species data in it. Phylogenetic relationship analysis is one of the common ways to recognize and know the diversity of an organism through reconstruction. The existing data is still incomplete because it does not display genetic data and needs to be updated to provide the latest information about species data in the Arboretum. Phylogenetic analysis is used to classify and provide information related to the evolution of kinship between existing tree species. This study aims to identify tree species and conduct a phylogenetic analysis of tree species in the USU Arboretum based on gene matK. The creation of this phylogeny tree was carried out using the neighbor-joining method using the Mega X application. The study’s results obtained tree data for as many as 62 species from 28 families. Based on the search for sequence data in the GenBank NCBI database, 51 species were obtained whose sequences were available. The phylogenetic tree with gene matK has a bootstrap value of 75-100%. They form 13 clades consisting of paraphyletic and monophyletic. Almost every type of tree clusters in the same family or genus.

Abstract
The Soraya Research Station is a critical forest research conservation area in Aceh Province. The forest area consists of essential and valuable tree species, including Dipterocarpaceae. This research aimed to determine the population structure and regeneration status of trees at the Soraya Research Station. The vegetation analysis was used for this purpose. The total height of each tree and the diameter at breast height (DBH) were also collected for population structure analysis. According to the research findings, the vertical stand structure in Soraya Research Station is dominated by stratum C, which is in good condition and forms an inverted J shape, with a decrease in the number of individuals as the DBH size increases. A total of 126 tree species with varying regeneration states were found. As much 40.47% (51 species) have new regeneration, 46.03% (58 species) have poor regeneration, 1.58% (2 species) have good status, 8.73% (11 species) have none status, and 3,17% (4 species) have fair regeneration. According to the findings, conservation efforts were urgently needed in this location due to regeneration problems.

Authors: Trimanto  , Renjana E , Angio M H , Metusala D 
Published: December 2024

Abstract
Kalimantan is known as one of the biodiversity hotspots. It harbours various endemic, rare, and endangered plant species. This research aimed to inventory plants and estimate the carbon stock of trees and poles in the Karendan forest, Central Kalimantan. The biomass and carbon storage of above-ground biomass (AGB) were measured using non-destructive methods. Around 88 species of tree stands were recorded, consisting of 51 trees and 61 species of poles (young trees). The average estimate of total carbon stock in the Karendan forest was 91.19 tons/ha, while the carbon stock value of trees was equivalent to poles, indicating forest regeneration. We observed forest disturbances caused by fires or selective logging in the past. The Dipterocarpaceae family (meranti) dominantly contributes to carbon biomass, either through its tree species, such as Shorea leprosula (25.07 tons/ha) and S. lamellata (5.05 tons/ha), or its pole species, including S. leprosula (3.39 tons/ha), and S. bracteolata (2.02 tons/ha). This family’s abundance of carbon-contributing trees indicates that the Karendan forest has a relatively high conservation value. The findings of this research are helpful for the management of coal mining companies, considering that this area is within the mining concessions.
Mycorrhizal Fungi in Seedlings of Meranti Bukit (Shorea platyclados) in Martelu Purba Nature Reserve
Authors: Rangkuti A B , Hartini K S , Sinaga D R , Amelia R 
Published: December 2024

Abstract

Shorea platyclados is a commercially important tree species known as Meranti Bukit, and it is nearly threatened. Its population is thought to have declined between 20 to 30% over three generations. This study aims to identify mycorrhizal fungi on S. platyclados seedlings in Martelu Purba Nature Reserve. The sampling method randomly sampled ten soil sample points and ten seedlings on three lines. Furthermore, isolation and identification of mycorrhizal fungi in these samples were carried out microscopically. The results showed the presence of several species of mycorrhizal fungi found in the rhizosphere of S. platyclados seedlings, namely the genus Glomus and Acaulospora. Mycorrhizal fungi are also found in root observations where vesicles and hyphae are found, which means that the roots colonize with mycorrhizal fungi, namely the ectomycorrhizal type. Applying mycorrhizal biofertilizer containing fungi from the genus Glomus and Acaulospora will provide good growth for S. platyclados.

Published: December 2024

Abstract

Purpose
Open fractures are associated with significant morbidity after trauma, which is driven, in part, by infection. Current literature and guidelines recommend that this patient population receive antimicrobial prophylaxis within 1 hour of emergency department (ED) arrival to minimize the risk of infection. The primary aim of this study was to investigate whether the addition of a trauma response to a pharmacy resident on-call program resulted in antibiotic administration within 1 hour of presentation to a higher proportion of patients with open fractures.

Methods
This was a retrospective, observational, quasi-experimental analysis that was conducted at an academic medical facility with a level 1 trauma center for patients presenting to the ED from January 2019 to December 2020 (preimplementation period) and from January 2021 to December 2022 (postimplementation period). Patients were included if they were 18 years of age or older and presented to the ED with an open fracture(s). Patients with independent fractures of fingers and those who died in route to or in the ED were excluded. The primary outcome was the proportion of patients with antibiotic administration within 1 hour of ED presentation for patients with open extremity fractures.

Results
A total of 292 patients met the eligibility criteria (49% in the preimplementation group and 51% in the postimplementation group). Patients were predominantly male (61% vs 58%), with an overall median age of 46 years. Following implementation of the on-call pharmacy resident trauma response, a significantly higher proportion of patients received antibiotics within 1 hour of presentation (70% vs 83%; P = 0.019). The median (interquartile range) time to antimicrobial administration was also significantly shorter in the postimplementation group (31 [16-68] minutes vs 19 [10-50] minutes; P = 0.005).

Conclusion
The addition of a 24-hour on-call pharmacy resident response in the ED was associated with improved antibiotic administration within 1 hour of presentation in patients with open fractures.
Electrical storm in a patient with Charcot–Marie–Tooth disease treated with radiofrequency ablation and subsequent serious complication of implantable cardioverter defibrillator implantation: a case report
Authors: Vrtal Jiří , Plášek Jiří , Václavík Jan , Šipula David , Dodulík Jozef 
Published: December 2024

Abstract

Background
Charcot–Marie–Tooth is the most common inherited neuromuscular disorder. Rarely, it can be associated with heart failure and various arrhythmic disturbances. This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot–Marie–Tooth disease.

Case summary
A 69-year-old male with a history of Type 1A Charcot–Marie–Tooth disease was admitted due to repetitive runs of ventricular tachycardia. Twelve-lead electrocardiogram, echocardiography, selective coronary angiography, and cardiac magnetic resonance did not clarify the cause of the electrical storm. As conservative therapy was not successful, radiofrequency ablation was chosen to treat the electrical storm. After this procedure, implantable cardioverter defibrillator (ICD) was implanted. The follow-up revealed severe perforation by the ventricular lead. An extraction was performed with no complications and a new lead was immediately implanted. The patient remains asymptomatic. Three episodes of non-sustained ventricular tachycardia were recorded during the last follow-up.

Discussion
This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot–Marie–Tooth disease after successful ablation for electrical storm. Due to a lack of evidence, atypical origin of arrhythmia, and clinical presentation, we did not consider this as idiopathic arrhythmia and decided to implant an ICD, which was complicated by severe perforation by the lead. Specific recommendations for preventing sudden cardiac death in rare cardiac conditions, such as Charcot–Marie–Tooth disease, still need to be refined.

Published: December 2024

Abstract
Rupture of abdominal aortic aneurysm (AAA) due to an isolated type II endoleak (TIIEL) is rarely reported, accounting for less than 1% of all TIIELs; typically, rupture associated with TIIEL is accompanied by type I or type III endoleaks. We report a case of ruptured AAA secondary to TIIEL without any other types of endoleaks, occurring late after endovascular abdominal aortic repair (EVAR). A 77-year-old man with a history of EVAR 11 years earlier presented with abdominal pain. Computed tomography revealed a ruptured AAA, likely due to TIIEL from the lumbar artery. He was on warfarin for atrial fibrillation, and his preoperative PT-INR was 6.05. After administering lyophilized human prothrombin complex concentrate, lumbar artery ligation and aneurysmorrhaphy were performed. Intraoperatively, there was pulsatile bleeding from the lumbar artery, which was sutured closed. No other types of endoleaks were observed. The postoperative course was uneventful, and the patient was discharged home.
Polytime embedding of intuitionistic modal logics into their one-variable fragments
Authors: Rybakov Mikhail , Shkatov Dmitry 
Published: December 2024

Abstract
We prove that propositional intuitionistic modal logics $\textbf{FS}$ (also known as $\textbf{IK}$) and $\textbf{MIPC}$ (also known as $\textbf{IS5}$) are polynomial-time embeddable into, and hence polynomial-time equivalent to, their own one-variable fragments. It follows that the one-variable fragment of $\textbf{MIPC}$ is coNEXPTIME-complete. The method of proof applies to a wide range of intuitionistic modal logics characterizable by two-dimensional frames, among them intuitionistic analogues of such classical modal logics as $\textbf{K4}$ and $\textbf{S4}$.
Civic Honours under Roman Rule
Authors: Heller Anna 
Published: December 2024

Abstract
In the Greek world, the award of honours by civic institutions or civic subgroups had a long history, going back to Classical times. This chapter examines the development of this honorific system from the 2nd century bc into the Imperial period, highlighting changes and continuities. The spread of honorific monuments went along with a new emphasis on individual excellence and family prestige in the language of public praise conveyed by honorific inscriptions. Traditional civic ideology nonetheless persisted: commitment to the community was still presented as the cardinal virtue for members of the elite, and the prerogative of the dēmos in the decision to honour was repeatedly asserted. A variety of honours, from ordinary to exceptional, rewarded a variety of benefactors, from the minor local notable to the emperor. Finally, the chapter reflects on the complex political, social, and cultural significance of civic honours for the Greek poleis under Roman rule.
