Lobster is one of Indonesia's marine resources that has high economic value and is very important for the country's economy, but excessive lobster fishing and smuggling of lobster seeds have caused a decrease in the productivity of marine resources and significant state losses, so effective law enforcement efforts are needed to protect Indonesia's marine resources from these illegal acts. The problem in this study is how the law enforcement by the West Tanjung Jabung Police against the crime of smuggling lobster seeds (Study of Case Register Decision Number: 144 / Pid.Sus / 2023 / Pn Klt), and what factors are the causes. The research method used is normative juridical, a type of legal research that focuses on the analysis and interpretation of legal norms that apply in a legal system. The study shows that the three defendants in the crime of smuggling lobster seeds were sentenced to 2 years in prison and a fine of IDR 5,000,000 based on Article 27 number 26 Article 92 of Law Number 6 of 2023 concerning Job Creation. The factors causing this crime include internal factors (economic and education) and external factors (politics, environment, and lack of security). Suggestions from the study are: Reviewing the lobster seed export policy. Improving coordination between law enforcement officers and community participation. Improving the capacity and competence of law enforcement personnel.

The right to health services for residents of Senawang Village and evaluating the legal protection mechanisms that can be taken by residents of Senawang Village due to the lack of health services, the type of research used is empirical legal research. The approach method used is a sociological approach and a legislative approach, the type of data is primary data, secondary data and tertiary data. While the data collection techniques are in the form of interviews, literature, and documentation. Finally, with the analysis of the data obtained from this study, it can be concluded that the fulfillment of the right to a healthy life is a basic right that must be guaranteed, because health is part of the primary needs of every human being, which is clearly regulated in Article 28 H paragraph (1) of the 1945 Constitution and Law of the Republic of Indonesia Number 17 of 2023. However, the reality in the field shows that the implementation and implementation of these various policies is still far from expectations. This shows a gap between the ideal regulations on paper and their implementation in real life. Therefore, synergy between infrastructure policies and health services is crucial because without concrete improvements in the infrastructure sector, the goal of realizing equitable, fair, and high-quality access to health services for all Indonesians will be difficult to achieve.

This study examines the integration of Maqasid al-Sharia the objectives of Islamic law into contemporary sustainable development frameworks, focusing on how Islamic ethical principles can guide social, economic, and environmental sustainability. Maqasid al-Sharia traditionally aims to preserve five core elements: religion, life, intellect, progeny, and wealth, all of which contribute to human well being. The research explores how these principles can be adapted to address modern challenges such as poverty, inequality, and environmental degradation, highlighting the potential of Maqasid al-Sharia to align with the United Nations Sustainable Development Goals (SDGs). Key Islamic principles, including justice (ʿadl), public welfare (maṣlaḥah), and ecological stewardship (khilafah), provide a moral framework for sustainable development, ensuring that economic growth is achieved alongside social justice and environmental preservation. The study also examines the role of Islamic finance, particularly tools like Sukuk, Zakat, and Waqf, in promoting sustainability by funding social welfare projects and supporting environmental initiatives. By comparing Maqasid al-Sharia with secular sustainability models, the research underscores the importance of integrating ethical and spiritual accountability into sustainability efforts. While secular models often prioritize economic growth, Islamic sustainability frameworks emphasize the interconnectedness of human development, social justice, and ecological balance, offering a more holistic approach. The findings suggest that integrating Maqasid al-Sharia into policy and development frameworks can provide a comprehensive, ethically grounded approach to addressing global sustainability challenges. Future research should focus on empirical studies to assess the practical application of Maqasid al-Sharia in real world sustainable development projects and policy making, particularly in Muslim majority societies.

The digital age has brought significant transformations to various sectors, including religious scholarship, where traditional structures of authority are being challenged by the rise of digital media and influencers. This study explores the implications of digital disruption in the Islamic context, focusing on how digital platforms are reshaping authority and epistemic legitimacy. In particular, the emergence of "religious digital creatives" is analyzed, highlighting how these influencers, often with little formal training but significant digital communication skills, have redefined religious authority. This shift away from traditional scholars, such as the ulama, who have been the custodians of religious knowledge, raises concerns about the authenticity and quality of religious teachings disseminated online. The study also examines the role of algorithm driven platforms, like AI-driven tafsir apps, and their impact on Islamic legal derivation and interpretation. While these platforms enhance accessibility, they also present challenges related to standardization and authenticity. By comparing traditional Islamic epistemology, which balances divine revelation, human reason, and scholarly rigor, with the decentralized authority of digital platforms, the study underscores the need for maintaining scholarly integrity and moral responsibility in the digital era. The research also highlights the importance of community trust in traditional scholarship, which is undermined by the lack of accountability in digital content. Ultimately, this study provides a framework for understanding the evolving relationship between Islamic epistemology and digital media, offering recommendations for preserving the core values of traditional scholarship while embracing the opportunities of digital innovation.

Ineffective management of household waste in rural areas, such as Aek Korsik Village, Aek Ledong District, Asahan Regency, causes air pollution due to traditional waste burning practices. This research aims to design and implement an environmentally friendly low-smoke waste incinerator as an alternative solution based on simple technology and local resources. The research methods used are technological engineering approaches and field studies, including tool design, trials, and environmental and social impact evaluation. The furnace is designed using heat-resistant local materials and mild steel, features a dual ventilation system and a smoke exhaust system with a simple filter, and has a combustion capacity of 5 kilograms per cycle. Preliminary studies show that the composition of waste is dominated by organic matter (60%), plastic and paper (30%), as well as the rest are inorganic. Testing over several weeks showed that an average burn time of 1.5 hours was able to reduce smoke emissions by up to 60% compared to conventional methods. The air quality around the test site has improved significantly, and the community has responded positively to the ease of use and environmental benefits of the furnace. This study concludes that low-smoke combustion furnaces are effective as environmentally friendly waste management solutions in villages, with recommendations for increasing combustion capacity and integrating other waste management methods to support sustainability and environmental preservation.

This study aims to analyze land cover changes in Pariaman City in 2013, 2018, and 2024 using Landsat-8 imagery with the support of the Google Earth Engine (GEE) platform and the Classification and Regression Trees (CART) algorithm. Land cover change is a critical issue in Pariaman City, as population growth, infrastructure development, and economic activities have driven significant land conversion. The classification generated eight land cover classes representing the general condition of the area. The analysis revealed that rice fields were the dominant land cover in all three periods; however, they experienced a substantial decline, indicating land conversion, particularly into settlements and road networks. In addition, the area of mangrove forests and water bodies in coastal regions decreased, while plantation areas in the eastern and southern parts of the city increased. Conversely, river land cover remained the smallest category, with annual fluctuations. The identified change patterns included urban sprawl (expansion of settlements into suburban areas), the conversion of productive land into infrastructure, and coastal degradation due to human activities and natural factors. The accuracy assessment produced overall accuracy and a Kappa index above 80%, while validation using the Mapping Accuracy method through Google Earth showed per-class accuracy rates above 75%, categorized as very good. These findings indicate that the use of satellite imagery and the CART algorithm in GEE is effective for monitoring land cover dynamics while providing valuable insights for local governments in formulating sustainable development policies and managing coastal environments such as those in Pariaman City.

Coal is one of the main energy sources and the largest contributor to national revenue; however, its management faces challenges related to limited availability and accuracy in reserve estimation. An essential aspect of mining management is monitoring the Run of Mine (ROM) volume, which plays a critical role in crushing, washing, and blending processes. This study aims to compare the accuracy of ROM volume measurements using Terrestrial Laser Scanner (TLS) and Unmanned Aerial Vehicle (UAV) methods in the production area of PT FAD, Berau Regency, East Kalimantan. A quantitative descriptive approach was employed, involving field data acquisition, three-dimensional modeling, and volume analysis using specialized software. The results show that ROM volume measured with TLS was 1,407.669 lcm, while UAV produced 1,387.357 lcm, with a difference of 20.312 lcm or 1.45%. This deviation is within the ASTM D6172-98 tolerance limit (<2%), indicating that both methods are valid. Although TLS offers higher accuracy, UAV is more effective and efficient in terms of measurement time, making it a reliable alternative for modern mining monitoring. This study provides practical insights for the mining industry in selecting ROM volume measurement methods that are not only accurate but also efficient in supporting sustainable operations and data-driven decision-making.

Aerial photo measurement aims to provide a real, fast, and interactive representation of the Earth's surface. Various methods of aerial photo acquisition and correction can be applied to obtain accurate results. The primary objective is to produce photos that present reliable and precise information consistent with actual conditions. A commonly used method in aerial photo mapping is the utilization of unmanned aerial vehicles (UAVs). The correction methods applied include direct correction, known as the Real-Time Kinematic (RTK) method, and post-processed correction, known as the Post-Processed Kinematic (PPK) method. This study aims to identify the highest horizontal orthophoto quality based on the Indonesian Geospatial Information Agency Regulation (BIG) No. 6 of 2018 concerning RBI map accuracy, by comparing the RTK and PPK methods, as well as variations in flight altitude during UAV data acquisition. The research conducted in Lemo II Village, Teweh Tengah District, North Barito Regency, Central Kalimantan Province revealed that the highest horizontal orthophoto quality was achieved using the PPK correction method at a flight altitude of 120 meters, with a horizontal RMSE value of 0.048 meters and an accuracy of 0.073 meters, which meets Class 1 standards at a 1:1000 scale. These values were obtained from tests conducted on 15 ICP points. Additional tests performed to determine the significance of model and method differences indicated that variations in flight altitude and photo correction methods have a significant impact on horizontal orthophoto quality.

An oil spill at sea is the release of oil, either directly or indirectly, into the marine environment originating from shipping activities, oil and gas business activities, or other activities. In order to handle and prevent pollution due to oil spills, the IMO (International Maritime Organization) has made regulations that must be implemented in the world of international shipping. MARPOL Regulation 73/78 Annex 1 is a regulation issued to overcome this. In implementing this regulation, ships are required to have equipment in the form of an Oil Discharger Monitor (ODM). This tool functions as a monitor of activities in the process of disposing of waste into the sea by ships. So in this study the researcher wants to discuss the role of ODM (oil discharger monitor) in preventing marine pollution in accordance with MARPOL 73/28 Annex I standards.

This study aims to analyze the welding results between two commonly used methods, namely Gas Tungsten Arc Welding (GTAW) and Shielded Metal Arc Welding (SMAW), using radiographic testing methods. Welding is an important process in industry that affects the quality and strength of metal joints. In this study, we will examine the quality of welding results from both methods through radiographic testing, which serves to detect defects in welded joints. The GTAW method is known for its cleaner results and minimizes defects, while SMAW is often used because of its convenience and lower cost. The welding process is a crucial factor in ensuring the durability and performance of metal structures, and selecting the right welding method is essential for specific industrial applications. This study will compare the two methods based on the results of radiographic and tensile tests, evaluating factors such as weld strength, defect occurrence, and structural integrity. The analysis will also examine the advantages and disadvantages of each method in terms of weld quality, cost-effectiveness, and practical applications in different industries. It is hoped that the results of this study can provide deeper insights into the selection of the right welding method for industrial applications, as well as contribute to the development of welding technology. Furthermore, the findings will support improvements in quality control and provide a scientific basis for future welding practices in various manufacturing sectors.

The management of incoming and outgoing mail at the Situbondo Technical Implementation Unit (UPT BLK) plays a crucial role in supporting the effectiveness of administrative activities. Currently, the process of recording letters is carried out manually using an agenda book, which is considered inefficient, makes searching for archives difficult, and takes a long time. These problems encourage the implementation of an information system that can facilitate faster, more structured, and more accurate processing of letter data. This study proposes the development of a computer-based information system using the waterfall method in the Software Development Life Cycle (SDLC). The data collection process is carried out through direct observation and interviews with administrative staff, so that system requirements can be clearly identified. The results of this study are an information system design with a simple, user-friendly, and easy-to-operate interface, so that employees can quickly understand the flow of use. The system developed allows the process of recording, archiving, and tracking letters to be more organized, practical, and efficient compared to previous manual methods. In addition, this system is also able to reduce the potential for human error in recording and accelerate the presentation of information when needed for administrative purposes and decision-making. Other advantages offered are easy data access and the availability of reliable, accurate, and timely information. With this system, administrative performance at the Situbondo Technical Implementation Unit (UPT BLK) is expected to significantly improve, both in terms of time efficiency, service speed, and orderliness in managing documents.

This study aims to analyze the results of Tungsten Inert Gas (TIG) welding joints made of 6061 aluminum with variations in current strength on mechanical properties. The current strength variations include 120 A, 140 A, and 160 A. The research method was conducted through laboratory testing, including impact testing, tensile testing, and microstructure testing. The results of the study indicate that variations in current strength have a significant effect on mechanical properties and weld joints. A current strength of 120 A produces a more uniform distribution of ferrite and pearlite phases in the weld zone compared to other variations. This is due to the electrical current during the welding process, which affects the heat input and cooling rate, consequently influencing the microstructure. As the current strength increases, the heat input increases, leading to changes in the material's phase composition and properties. Additionally, tensile test results showed an increase in tensile strength with increasing current strength, indicating that the welding process at higher current strengths contributes to improved material bonding and strength. Microstructure analysis revealed a more homogeneous phase distribution at higher current levels, which contributes to better weld quality and performance. This study provides valuable insights into how variations in current strength can be optimized for improved mechanical properties in TIG welding of 6061 aluminum, offering a basis for better control of welding parameters in industrial applications.

This research is a Classroom Action Research (CAR) conducted in two cycles. The subjects were 24 students of class XII TM 2 of the Mechanical Engineering Expertise Program at Semen Padang Vocational School in the odd semester of the 2025/2026 academic year. Data collection was carried out through learning activity observation sheets, practical assessment sheets, and multiple-choice tests to measure students' cognitive learning outcomes. The implementation of Creative Products and Entrepreneurship learning at Semen Padang Vocational School was previously teacher-centered. Students tended to be passive listeners during the learning process, which led to low participation, minimal interaction, and a lack of understanding of the material. As a result, most students were unable to achieve the Minimum Completion Standards (SKM). Based on this, the Jigsaw Cooperative learning model is considered suitable for application in Creative Products and Entrepreneurship learning, because it is able to create a student-centered learning atmosphere and encourage active involvement and cooperation between students. The results of the study prove that the application of the Jigsaw Cooperative learning model is effective in improving student learning outcomes. This is based on the average student learning outcomes in cycle 1 of 75.2, where 17 students were declared complete. In cycle II, the average student learning outcomes were 85.2 with 21 students declared complete. The significant improvement in cycle II indicates that the Jigsaw Cooperative Learning model is not only effective in improving cognitive learning outcomes but also able to improve the quality of interactions between students in the learning process. Students become more active in discussions, disseminating information, and are responsible for understanding the material they are learning and sharing with their groups.

Food security is a fundamental aspect of independent and sustainable village development. Kajarharjo Village has abundant natural resource potential, such as cassava and various herbal plants. However, the utilization of this potential is still less than optimal, both in terms of food processing and the implementation of environmentally friendly agriculture. This condition encourages the need for community service activities oriented towards food innovation and strengthening sustainable agriculture. This service activity was carried out using a participatory and applied approach at the Kajarharjo Village Hall. The main target is the village community, especially housewives and farmers. The program is implemented through two main activities, namely: (1) training in making cassava leaf nuggets as a nutritious food, an alternative local product, and a household business opportunity; and (2) training in making organic boosters from natural ingredients as a more environmentally friendly substitute for chemical fertilizers. Implementation methods include counseling, demonstrations, direct practice, and interactive discussions to ensure active community involvement. The results of the activities show an increase in community knowledge and skills. Housewives are able to process cassava leaves into products with nutritional and economic value, while farmers gain skills in mixing organic boosters that can improve soil quality and agricultural yields without relying on chemical fertilizers. The participants' enthusiasm was also evident in their active participation in the practical exercises and their desire to apply the knowledge gained in their daily activities. In conclusion, this activity successfully encouraged the utilization of local potential in Kajarharjo Village through food innovation and organic farming. Empowering the community through cassava leaf processing and organic fertilizer production not only strengthens food security but also opens up business opportunities, maintains environmental health, and supports the development of an independent, healthy, and sustainable village.

Taro flour (Colocasia esculenta L. Schott) is a local food ingredient with significant potential to be developed as an alternative carbohydrate source. Its high starch content, dietary fiber, and functional properties make taro flour a promising candidate for use in various food formulations.

However, the development and application of taro flour face several challenges, such as high levels of antinutritional compounds (particularly oxalates), variability in characteristics among cultivars, limited processing technology, and low consumer acceptance. Therefore, innovation in processing techniques is needed, including pre-treatment methods to reduce antinutrient content, starch modification to enhance functionality, and composite formulation with other food ingredients to expand product applications. This article aims to establish a comprehensive conceptual framework for the innovative development of taro flour, focusing on processing technology, functional value, and commercialization potential. Through this approach, the development of taro-based products is expected to increase added value, support local food diversification, and strengthen national food security.

Marine conservation areas play a crucial role in maintaining the sustainability of aquatic ecosystems and fishery resources. However, many fishing vessels still violate regulations by entering and exploiting conservation areas without permission. This study aims to analyze the compliance level of fishing vessels with conservation regulations in the Anambas Islands, identify the factors contributing to non-compliance, and evaluate the effectiveness of the imposed sanctions. The research employs a qualitative and quantitative descriptive approach, utilizing SWOT analysis to assess internal and external factors affecting compliance. Data were collected through vessel movement monitoring using the Vessel Monitoring System (VMS), interviews with fishery inspectors, and analysis of relevant policy documents. The findings indicate that many fishing vessels fail to comply with conservation regulations, mainly due to fish migration into conservation areas, deliberate violations by business operators seeking higher profits, and a lack of understanding among captains regarding conservation boundaries. Additionally, limited human resources and monitoring facilities hinder effective law enforcement. Although sanctions are regulated under Government Regulation No. 85 of 2021, their effectiveness remains low, as evidenced by recurring violations. Therefore, strengthening supervision, optimizing monitoring technology, and raising fishermen’s awareness of conservation regulations are necessary to enhance compliance among fishing vessels and preserve marine ecosystems.

Magnetic Resonance Cholangio Pancreatography (MRCP) is an important non-invasive imaging technique for the diagnosis of abnormalities in the biliary and pancreatic systems, including pancreatic mass and colletiasis. The use of an additional sequence of Diffusion Weighted Imaging (DWI) with b-value variations and image segmentation is thought to improve the accuracy of mass limit measurements on MRCP checks. This study aims to analyze the effect of b-value variation and image segmentation on the additional sequence of DWI in the MRCP examination of the accuracy of the mass limit measurement. The research used quantitative methods with MRCP image data capture equipped with a DWI sequence with b-value variations, using the matlab method. Image segmentation is performed to identify mass boundaries. Measurement accuracy is analyzed and compared between the variation in b-value and the segmentation techniques used. Research results show that variation of b-value 800 and image segmentation in additional DWI sequences have a significant effect on the improvement of accuracy of mass limit measurement on MRCP examinations. The b-value 800 variation is more optimal than the b-value 50 and the appropriate segmentation method can clarify the mass limit so that it supports a more accurate diagnosis. Sequence variations in b-value and image segmentation in the additional DWI sequences in MRCP examinations play an important role in improving the accuracy of mass limit measurements, which can aid in the diagnosis and management of diseases especially in lesion cases.

Magnetic Resonance Imaging (MRI) with Arterial Spin Labeling (ASL) is a non-invasive technique commonly used to assess cerebral perfusion, especially in stroke patients. However, ASL images often suffer from low contrast and high noise, which can hinder diagnostic accuracy in visualizing perfusion areas and detecting ischemic lesions. Image enhancement techniques, such as the unsharp mask, offer a potential solution to improve image quality. The effectiveness of this enhancement depends on the kernel size used in the unsharp mask filter. This study evaluates the impact of different kernel sizes (3×3, 5×5, and 7×7) on the quality of ASL brain images, focusing on both quantitative and qualitative improvements. A total of 63 ASL brain MRI images from stroke patients were processed using unsharp mask filters with the three kernel sizes. Quantitative analysis measured Signal-to-Noise Ratio (SNR) and Contrast-to-Noise Ratio (CNR), while qualitative assessment involved three radiologists independently evaluating five aspects of image quality: perfusion area clarity, grey-white matter contrast, ischemic lesion boundary visibility, noise level, and overall visual quality. Statistical tests, including Friedman and Wilcoxon, were applied to compare results across the kernel sizes. Results revealed that the 3×3 kernel achieved the best results in both quantitative and qualitative assessments, with the highest SNR, CNR, and visual quality scores. Significant differences (p < 0.05) were found between kernel sizes, confirming the superiority of the 3×3 kernel. The 7×7 kernel reduced noise but caused oversmoothing, negatively impacting image sharpness. In conclusion, the 3×3 kernel provides an optimal balance between noise reduction and edge preservation, enhancing ASL brain image quality for stroke diagnosis.

Urological examinations using Multi Slice Computed Tomography (MSCT) often require the use of diuretic agents to enhance the visualization of the urinary tract system. However, the use of synthetic pharmacological agents may sometimes lead to undesirable side effects. The aim of this study was to evaluate the effectiveness of ginger extract (Zingiber officinale) as a natural diuretic alternative in MSCT urological examinations. This research utilized an experimental design, comparing two groups: one that was given ginger extract before the examination and another control group that did not receive any additional treatment. Key parameters observed included the degree of urinary tract distension, MSCT image quality, and the smoothness of contrast media excretion. The results indicated that the administration of ginger extract significantly increased the degree of ureteral and urinary bladder distension, leading to improved image visualization quality compared to the control group. These findings suggest that ginger extract can serve as a promising natural diuretic alternative for MSCT urological examinations. However, further studies with larger sample sizes are necessary to confirm the validity and reproducibility of these results. Ginger extract offers an innovative and potentially safer approach to improving the effectiveness of MSCT scans without the side effects associated with synthetic diuretics.
