The Impact of Changes in Criminalization in the Law on Environmental Protection and Management by the Job Creation Law on Achieving a Deterrent Effect for Environmental Offenders 1Muhammad Natsir, 2Zaki Ulya, 3Andi Rachmad, 4Liza Agnesta Krisna Faculty of Law Samudra University Abstract Criminal regulation in environmental management is an important instrument to enforce ecological law effectively. In Indonesia, criminal arrangements are clear in Law Number 32 of 2009 concerning Environmental Protection and Management, and various views of ecological law experts emphasize that criminal sanctions are needed to create a deterrent effect and ensure environmental sustainability. In different international forums, such as the Conference of the Parties (COP) in the framework of the Climate Change Convention, many countries encourage stricter enforcement of criminal law to address transnational environmental crimes. This shows the importance of criminal regulation not only at the national level but also in a global context. The enactment of Law No. 11 of 2020 concerning Job Creation has amended the Environmental Protection and Management Law by removing several criminal provisions so that it shows that the Job Creation Law focuses more on administrative sanctions mechanisms rather than criminal sanctions to reduce the deterrence against violations that have the potential to damage the environment. a Weakening supervision and law enforcement in environmental protection. the elimination of criminal sanctions and replacement with administrative sanctions can reduce the deterrent effect for violators. The purpose of this paper is to find out the legal arrangements for environmental crimes and their impact on changes in criminal provisions in the Environmental Protection and Management Law. The method used in this paper is normative jurisprudential legal research, with a focus on identifying criminal sanctions against perpetrators of environmental crimes, using a statutory approach. The overall results of the research show that with the repeal of several criminal provisions in the Environmental Protection and Management Act, the criminal provisions in environmental management lack a deterrent effect. The reintroduction of strong criminal provisions is an important component in maintaining the balance between economic development and environmental protection.

Exploring the Influence of Lifestyle and Financial Technology on Gen Z Financial Management: Does Love of Money Matter? Siti Zhuraira, Muhammad Rizal*, Rini Chandra, Suri Amilia Fakultas Ekonomi dan Bisnis, Universitas Samudra *Corresponding Author Abstract This study aims to examine the influence of financial confidence, parental income, lifestyle, and financial technology on the financial management of Generation Z, with love of money as a moderating variable. Data was collected through a questionnaire distributed via Google Forms, using non-probability sampling, specifically purposive sampling. A total of 296 respondents participated in this quantitative research, and the data was analyzed using the SmartPLS method. The results indicate that financial confidence and parental income significantly influence the personal financial management of Generation Z. However, lifestyle and financial technology do not have a significant impact. The moderation analysis reveals that love of money moderates the relationship between financial confidence and financial management, but it does not moderate the relationships between parental income, lifestyle, financial technology, and financial management in Generation Z. This study contributes to the Theory of Planned Behavior (TPB) by demonstrating how financial confidence-reflecting perceived behavioral control-interacts with attitudinal constructs such as love of money to shape financial behaviors in Generation Z. By highlighting the role of individual financial attitudes alongside external influences like parental income, the findings enrich the understanding of how personal and contextual factors jointly impact financial decision-making within the TPB framework.

MACRO SOCIO ECONOMIC DETERMINATION OF INCLUSIVE ECONOMIC DEVELOPMENT IN INDONESIA Rinaldi Syahputra, T. Zulham, Sofyan Syahnur, Taufiq C. Dawood Universitas Samudra Abstract Inclusive economic development can occur when there is strong economic growth. Until 2012, Indonesia^s economic growth has not been inclusive in terms of reducing poverty, reducing inequality or increasing employment opportunities. The process of inclusive economic development will be accelerated by a more inclusive relationship between economic sectors and an educated population. The purpose of this study is to simulate the relationship between democracy, investment, human capital, trade through exports, inflation as a representation of the domestic economy, and inclusive economic development. This study uses panel autoregressive distributed lag (ARDL) model with KAO cointegration test used in this study and comparison with panel vector error correction model (VECM) as a form of government policies implemented related to inclusive economic development and cointegration of the variables studied in the short run and long run. The dataset used in this study covers several provinces in Indonesia and covers the period 2011 to 2022. The findings of this study are that with an emphasis on inclusiveness, Indonesia is actively pursuing broad and sustainable economic reforms. The three main pillars of a transition are the eradication of poverty and extreme poverty, the improvement of health and education standards, the promotion of applied research and industrial revitalisation, and the strengthening of corporate competitiveness. All independent factors have substantial short-term and long-term relationships with the dependent variable, which affects the sustainability of economic development. Changes in one variable will have an impact on the other variables. Changes or improvements in the independent variables impact what Indonesia can consistently offer to create employment opportunities. This study shows that maintaining and improving community access and political engagement is positively correlated with necessary economic policies.

Flood Discharge Modeling in Krueng Langsa Watershed: Comparing Nakayasu and SCS-CN Methods for Risk Mitigation Eka Mutia (a*), Ellida Novita Lydia (a), Ika Adelia Winata (a), Nurul Fadhillah Siregar (a) a) Department of Civil Engineering, Faculty of Science and Technology, Universitas Samudra, Langsa, 24416, Indonesia Abstract Flood discharge modeling is crucial for disaster risk mitigation, as floods account for 40% of natural disasters globally, causing USD 82 billion in annual losses. In Indonesia, frequent floods, especially in high rainfall areas like Aceh, exacerbate the risk. Langsa City, located on the eastern coast of Sumatra, regularly experiences flooding, especially in the Krueng Langsa Watershed, which receives an annual rainfall of 2300 mm. Poor water resource management, along with environmental degradation, exacerbates the flood risk in this region. This study aims to model flood discharge in the Krueng Langsa Watershed using two hydrological methods: the Nakayasu Synthetic Unit Hydrograph and the Soil Conservation Service Curve Number method. A comparison between these two methods was conducted to assess their accuracy in predicting flood discharge for various return periods. The methodology involved collecting rainfall data from local stations and estimating missing data using the Normal Ratio Method. Data consistency was tested using the double mass curve method. The Hydrologic Modeling System software was used to simulate runoff using both the Nakayasu and SCS CN methods. The results showed that the Nakayasu method provides more accurate flood discharge predictions, with an estimated peak discharge of 135 m3/s for a 25 year return period. In contrast, the SCS CN method proved less reliable under high-rainfall conditions. Therefore, the Nakayasu method, combined with HEC HMS simulations, is considered more reliable for flood management planning and infrastructure development in the Krueng Langsa Watershed.

^Optimization of Microhydro Power Potential: A Case Study of Alur Batu Waterfall in Aceh Tamiang for Sustainable Energy Solutions^ Ellida Novita Lydia (a*), Lely Masthura (a), Eka Mutia, Winda Apriana a) Department of Civil Engineering, Faculty of Science and Technology, Universitas Samudra, Langsa, 24416, Indonesia Abstract A Micro Hydro Power Plant is a small-scale hydropower system with a low head and an output of less than 200 kilowatts. In Selamat Village, there are five waterfalls, one of which is the Alur Batu Waterfall, with a height of approximately 11.8 meters, and it flows continuously, even during long dry seasons. This study aims to identify the characteristics of the water flow, discharge, and head at the research site, and to calculate the electrical power potential based on both flow discharge and dependable discharge. The research employs a quantitative approach, with direct field measurements accompanied by climatological data analysis to assess the energy potential. The climatological data analyzed includes rainfall, temperature, solar radiation, humidity, and wind speed, which are processed using the FJ. Mock method. The physical characteristics of the water flow show that the water surface is choppy and foamy, moving irregularly and turbulently due to the steep gradient and rocky terrain of the waterfall. Based on the analysis using the Reynolds number, the Alur Batu waterfall exhibits turbulent flow, with a head height of approximately 8.6 meters. With a field flow discharge of 0.89 m3/s, the potential electrical power generated is 48.75 kW. The dependable discharge, at 0.59 m3/s, can generate a potential electrical power of 32.28 kW. Based on the analysis of PLTMH potential using both the field discharge and dependable discharge, the dependable discharge is more suitable for planning and calculating the potential of PLTMH, as it provides a more realistic representation of water availability throughout the year, whereas field discharge reflects momentary conditions that may fluctuate.

(d) Department of Geography Education, Faculty of Education, University Samudra, Langsa, 24415 Langsa City, Indonesia Abstract Langsa City, located in Aceh Province, has extensive traditional shrimp pond areas covering 2,067.50 hectares, contributing 15% of the province^s total shrimp production. However, shrimp production has declined from 8,348 tons in 2010 to 6,523 tons in 2018. One contributing factor is the deterioration of the pond gates, particularly in the Sungai Pauh Tanjung area, made of wood, which is affected by flooding and climate change. High salinity levels due to climate change accelerate the decay of wooden structures, limiting their lifespan. Leakage often occurs at the submerged areas of the gates, causing shrimp and feed to escape unnoticed. Flood pressure leads to the destruction of these aging wooden gates. To address this issue, it is essential to enhance the durability of pond gates to prevent crop losses for shrimp farmers. This research aims to improve the durability of pond gates using eco-friendly hybrid concrete incorporating Palm Oil Fuel Ash (POFA) and Palm Oil Clinker (POC) in the Sungai Pauh Tanjung area. The methodology begins with a situational analysis of the pond gates to identify problems, followed by designing the gates with hybrid concrete and calculating the mix design using materials sourced from nearby palm oil mills. Testing of hybrid concrete specimens is conducted at the Integrated Laboratory of Samudra University at 7, 14, and 28 days. The final stage involves reinforcing and pouring hybrid concrete for the pond gates, measuring 80 cm wide and 100 cm high. The application of K-250 quality technology has successfully addressed leakage and flood pressure issues. Training and assistance in the construction process are provided to local farmer groups to facilitate knowledge transfer, enabling broader application of the hybrid concrete gates. The results indicate that these concrete gates effectively prevent leaks, decay, and extend their lifespan.

(c) Department of Civil Engineering, Faculty of Civil Engineering, Cut Nyak Dhien Sains University, 2435 Langsa City, Indonesia Abstract Seuneubok Punteut Village, located in Peudawa District, East Aceh Regency, has a significant paving block processing center that contributes to local economic development. However, one of the micro, small, and medium enterprises (MSMEs) in this village still relies on conventional production methods, which adversely affect the quality of the paving blocks produced. Testing results indicate that the quality of the paving blocks only reaches 10-15 Mpa, categorized as Class C according to SNI, which indicates low durability. This type of paving block is only suitable for non-structural construction components. The main factors contributing to this low quality include the manual mixing process conducted with a shovel on the ground, leading to inconsistencies in the mixture. Additionally, the manual compaction without adequate equipment also contributes to suboptimal results. Non-compliance with job mix design procedures results in inconsistent material mixtures, thereby lowering the final product quality. This research aims to identify and address these issues by proposing the use of palm kernel ash as an additive. Palm kernel ash, a waste product from the combustion of palm kernel shells at high temperatures (700-800Celcius), has the potential to enhance the mechanical properties of paving blocks and bricks. By incorporating palm kernel ash into the mixture, it is expected that the product quality can be improved to meet the required standards for various construction applications. This research is anticipated to serve as a model for the development of material processing industries in other regions facing similar challenges.

Imbalance labeled data occurs when one class in the dataset is significantly smaller than others, leading to decreased model performance, particularly in predicting the minority class. The algorithm such as SVM frequently struggle to address imbalanced data effectively. Therefore, using techniques like SMOTE to balance data and boosting methods like XGBoost to improve accuracy is crucial. This study integrates SMOTE, SVM, and XGBoost, resulting in a combined model called SSVMXGB as we called it the ensemble model. This approach provides a more robust solution to classify the problems with imbalanced datasets by significantly improving performance through data balancing and model boosting. The results of the study show that on the village funding dataset, which contains 3078 records, SSVMXGB achieved an accuracy of 94%, SMOTE-SVM 97%, SVM-XGB 84%, and SVM 85%. On the online learning dataset with 1200 records, SSVMXGB achieved an accuracy of 98%, SMOTE-SVM 95%, SVM-XGB 90%, and SVM 81%. These results demonstrate that the SSVMXGB algorithm effectively handles imbalanced datasets, particularly by leveraging SMOTE to ensure better representation of minority classes, even in datasets with smaller record counts. Additionally, combining the strengths of SVM in non-linear classification and XGBoost in correcting previous prediction errors enhances the model^s overall performance Keywords: Classification- SMOTE- SVM- XGBoost- Ensemble Share Link | Plain Format | Corresponding Author (M.

The Phenomenon of Flow Through Four Circular Cylinders Arranged in a Line Square Banta Cut (a*)- Fazri Amir (a*)- Teuku Azuar Rizal (a*)- Intan Yusup (a*)- Arif Manuel Sidauruk (a*)- Luthfi Hakim (b*) a) Department of Mechanical Engineering, Samudra University, Langsa City, Aceh 24415, Indonesia b) Department of Mechanical Engineering, Islamic Majapahit University, Mojokerto, 61363, Indonesia Abstract The application of circular cylinders is prevalent in various engineering fields, such as in underground pipe networks, offshore structures, and shell tube heat exchangers. Numerous studies have identified the presence of drag force (CD) and lift force (CL) that occur when fluid flows past an arrangement of cylinders. Consequently, further research was conducted using numerical simulations to investigate methods for reducing CD and CL in these circular cylinder configurations. This study focused on four circular cylinders arranged in a square formation. The main cylinder has a diameter (D) of 25 mm, while the disturbing body (DB) diameter (d) is 4 mm. The cylinder arrangement is placed in a narrow channel with a square cross-section measuring 300 mm in height and 1500 mm in length, leading to a blockage ratio of 25 percent. The tests were conducted at Re is 50.000. Three configurations of the DB were examined, positioned at angles of 0, 90, and 270 degrees in front of the two upstream cylinders, with a gap distance (G/D) of 0.16 relative to the circular cylinder. This numerical simulation study was performed using 2D Unsteady RANS with Ansys 2022 R2 software, employing a structured mesh type and the k omega SST turbulence model. The results indicate that the distance (L/D) and the use of DB significantly affect the drag and lift forces in the arrangement of the four staggered circular cylinders. Specifically, the addition of DB around the two upstream cylinders at angles of 0, 90, and 270 degrees proved to be highly effective in reducing both CD and CL for cylinder 3 and cylinder 4 Keywords: Circular cylinder- disturbing body- k omega SST- coefficient of drag- coefficient of lift Share Link | Plain Format | Corresponding Author (BANTA CUT)

While machine translation serves as a useful tool for comprehending translated textual content in a general sense, it is important to note that automated machines still possess inherent weaknesses and limitations. The translation of text from oral stories, particularly in relation to language and cultural differences, proves to be a challenging task. This research was undertaken utilizing a qualitative-descriptive approach. The primary objective of this research is to assess the level of translation quality achieved by machine translation in terms of accuracy, acceptability, and readability, and to compare these results with the translations provided in the source, lastly to know the understanding of students about translation quality of oral stories via machine translation. The findings of this research indicate that 80% of the translations exhibit a high level of accuracy, while 20% are somewhat less accurate. Furthermore, 20% of the translations are deemed acceptable, while 80% are regarded as less acceptable. Finally, 37.5% of the translations demonstrate a high degree of readability, whereas 62.5% exhibit a moderate level of readability. Upon comparing the translation results obtained from machine translation with the original translations presented in real book, it was determined that 100% of the translations in the book were found to be satisfactory in terms of accuracy, acceptability, and readability. Although the translations from English to Indonesian of comedy texts via Google Translate are deemed satisfactory, there is still room for improvement and ongoing development in order to enhance the quality of these translations. Also, all students are well aware of the translation quality of oral stories via machine translation.
