<![CDATA[Along with the increase in trade activities by sea, the need for adequate port facilities, including the Container Yard, is becoming increasingly important. This study aims to analyze the needs of stacking yard facilities at Sorong Container Port. The research method used is a quantitative approach with data collection through documentation studies and observation at the research location, namely Sorong Container Port. The results showed that although the flow of containers is projected to continue to increase until 2026, the use of the stacking yard is still low with a Yard Occupancy Ratio (YOR) ranging from 12.43% to 14.59%. This indicates an opportunity to improve port operational efficiency. This study recommends optimizing the use of the piling yard, improving the loading and unloading process, developing infrastructure, and improving coordination with stakeholders. Further analysis of infrastructure investment and comparative studies with other ports are also recommended.]]>

<![CDATA[This study aims to determine the perception of coastal communities in Central Tapanuli towards waste management as an effort to maintain marine sustainability and formulate waste utilization activities as an effort to increase the income of coastal communities in Central Tapanuli. The research method used in this study is a mixed research method. This study was conducted in three locations, namely in Lubuk Tukko Baru Village and Muara Nibung Village, Pandan District and in Jago Jago Village, Badiri District with a total of 100 respondents in the study. Based on the results of the study, the results of the perception of "community understanding of waste management in coastal areas" were obtained with an overall average value of 91.16%, meaning that all respondents strongly agreed or understood very well. Then for the results of the perception of "understanding of coastal environmental cleanliness and waste utilization to increase family income" the overall average result was 53%, with the category sometimes or less understanding. Then the results of several activities were obtained that were appropriate for coastal communities in Central Tapanuli Regency in utilizing waste as an effort to increase income with the management categories divided between organic waste and non-organic waste. Organic waste is very possible to be used for maggot cultivation activities or commonly called Black Soldier Fly (BSF) maggots and making candles and soap for households from used cooking oil. Then for non-organic waste, it is very possible to carry out activities to form a Waste Bank, establish a skills center that provides economic added value, and implement cooperation with private and government companies in managing non-organic waste.]]>

<![CDATA[Concrete technology has significantly advanced and remains an interesting research topic. The demand for cement usage rises significantly due to concrete usage in various sectors. Cement production leads to air pollution issues and causes a greenhouse effect, even in the modern filtration era. Fly ash is an industrial waste that has been identified as a viable substitute for cement due to its pozzolanic properties. Silica Sand is sandblasting waste, where added value is needed. This study investigates the effectiveness of fly ash substitution in the cement portion of cementitious composite materials as an effort to minimize cement usage. Using sandblasting waste is an effort to implement 3R activity (reduce, reuse, recycle) for maritime waste. Compressive and tensile tests were evaluated in the variation of fly ash substitution for cementitious composite reinforced by coco fiber and wiremesh model. The results show that a 40% fly ash substitution gives the highest compressive strength of 32.98 MPa and the tensile strength of 5.90 N/mm². The best model composition provides the increments of compressive and tensile strength compared to the control specimen at 43.60% and 12.60%, respectively. ANOVA tests confirmed the significance of the enhancing effect as the presence of fly ash, both for compressive and tensile strength. Additionally, static analysis simulations using Fusion360 software were performed and indicated that the cementitious composite lawn table prototype’s design is safe and has good formability, as a safety factor performed 2.26, exceeding the required value of 2.00. This result explicates that fly ash and waste materials can be effectively used in cementitious composites for practical applications.]]>

<![CDATA[Indonesia is known as an “undersea paradise” because of its extraordinary wealth of marine biodiversity and fishery resources. With this nickname, coastal communities should have a decent life. However, in reality, their welfare is not in line with the wealth of marine resources, especially for fishermen. The lives of fishermen are often colored by economic challenges, weather uncertainty, and environmental changes that impact their welfare. This study aims to identify sources of livelihood, identify levels of welfare, and identify livelihood strategies carried out by fishing households. Through a survey that we conducted on 35 small-scale fishing households on the West Coast of North Sumatra, we found that most of them were still classified as less prosperous. Although the livelihood analysis shows that their sources of income are quite diverse, the contribution of income outside of fishing has not been able to improve their level of welfare. The results of this study also show that fishermen are not a passive group of people. Realizing the uncertainty in their livelihoods, they try to take advantage of existing opportunities by implementing livelihood strategies. The livelihood strategies carried out by fishermen are classified into economic dimensions, ecological dimensions, and social dimensions.]]>

<![CDATA[The increasing environmental concerns surrounding fast fashion and the accumulation of waste materials have prompted a need for alternative, sustainable materials in various industries. This study aims to investigate the feasibility of utilizing recycled carbon and polyester composites for ship hull construction. An experimental approach is employed, focusing on tensile testing of material specimens, including carbon fiber and polyester, in accordance with ASTM D3039 standards. The method involves creating composite specimens, subjecting them to tensile tests, and analyzing the results through standard deviation to compare tensile strength and maximum load. The results demonstrate that the composites exhibit suitable mechanical properties for ship hull construction, with polyester showing an insignificant difference compared to carbon fiber composites. These findings provide a reference for future applications in shipbuilding, contributing to environmental sustainability efforts by repurposing waste materials.]]>

<![CDATA[Glass strain carp (Cyprinus carpio) is highly demanded by farmers due to its delicious, dense meat and fewer spines. To meet the increasing demand for carp, it is necessary to improve the efficiency of aquaculture. The season is known to stimulate one hormone production. The purpose of this study was to determine the effect of season (rainy and dry seasons) on reproductive hormones (follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and estrogen, and interstitial cell-stimulating hormone)) in C. carpio glass strain. Idi research was conducted using the descriptive method by rearing fish in different seasons (rainy season and dry season). The results showed that the reproductive hormone of C. carpio strain glass increased during the rainy season. During the rainy season, changes in the environment and water flow patterns are detected by the fish's sensory system. The results showed that the highest hormones in a row were: ICSH hormone (12.82 pg/mL), FSH hormone (male: 3.73 ng/mL; female: 12.10 ng/mL), LH hormone (12.48 MIU/ml), testosterone hormone (9.27 ng/mL) and estrogen hormone (21.84 ng/mL). Further research is needed to observe the growth and abnormality of fish larvae produced in different seasons.]]>

<![CDATA[As cities grow, the demand for energy increases, necessitating a corresponding increase in energy supply. Since urban areas consume the majority of the world’s energy, switching to renewable energy sources is essential. Wind energy is one of the most popular renewable energy sources for generating electricity. Vertical-axis wind turbines (VAWTs) are used in urban areas due to their advantages, with cross-flow wind turbines (CFWTs) being one type. However, the efficiency of CFWTs is relatively low, necessitating the application of augmentation devices. This study aims to find the optimal configuration between CFWTs and Omni-Directional Guide Vanes (ODGV), using 6DOF dynamic mesh methods in ANSYS Fluent with varying the turbine blade counts and the addition of ODGV. The results showed that the 18-blade configuration exhibits the highest improvement with ODGV, demonstrating a remarkable 71 percent increase in the power coefficient. In general, the highest performance is achieved by the 20-blade turbine with a 6-blade ODGV configuration, with a power coefficient of 0.2455, which is 30 percent higher than the baseline 20-blade turbine. These findings indicate that the addition of ODGV significantly improves the performance of cross-flow wind turbines.]]>

<![CDATA[More than a year has passed since Francisco Pérez-Arribas (2023) introduced a parametric-based hull design method using Python scripts, beginning with the cross-sectional area (CSA) design. Several experimental studies have been carried out to improve the method and the quality of ship design. This study aims to generate an optimal hull design by utilizing normal vectors derived from the x and y vectors. These normal vectors are applied parametrically to determine the shape of the hull. The study also employs a cubic spline-based parametric technique for designing yacht hulls. The purpose of this study is to introduce the concept of parametric design through the development of visual programming used to form cross-sectional area curves and generate hull geometry. This study also discusses both the advantages and limitations of using visual programming approaches to accelerate the design process. By varying the CSA shape of the DelftShip model, the resulting parametric model has a high level of accuracy, with a difference of - 0.097016% in LCB and -0.28785% in volume when compared to the DelftShip model. results from Grasshopper reveal significant differences, particularly below a draft of 0.475, where the CP values from Grasshopper are lower than those from DelftShip. The parametric approach using normal vectors not only facilitates design exploration but also holds the potential to enhance overall hull design quality and optimization.]]>
