This study aims to analyze in depth the cultural construction of independence in Islamic boarding schools through the perspective of educational sociology. The main focus of this study is to explore how social structures, power relations between kyai and santri, and hidden curriculum mechanisms contribute significantly to the formation of santri's independent character. This research is motivated by the discrepancy between national educational goals and the reality of the crisis of independence often found in formal educational institutions. Using descriptive qualitative methods through a literature study and critical synthesis approach, this study examines the phenomenon of independence as a sociological product. The results of the study show that the independence of santri is not merely obedience to formal rules, but rather the result of the formation of internalized habitus through strict daily discipline and the accumulation of cultural capital transmitted by the figure of the kyai. These findings confirm that the charismatic relationship between kyai and santri serves as the main channel for transmitting the values of initiative and responsibility. Furthermore, the hidden curriculum manifested in the daily exemplary behavior of the kyai has proven to be more effective in shaping the autonomy of santri than conventional classroom instruction. The implications of this study confirm that the educational ecosystem model in Islamic boarding schools can serve as a strategic reference for modern educational institutions in overcoming the challenges of character degradation and independence among students in the contemporary era.

This research aims to examine the role of music in the construction process of the traditional Karo house, Siwaluh Jabu, in Lingga Cultural Village, Karo Regency, North Sumatra. In Karo culture, music is not merely a source of entertainment but serves as a symbolic and spiritual medium that reflects cultural values, social cohesion, and the community’s belief system. This study employs a qualitative descriptive method with an ethnographic approach through field observation, in-depth interviews with traditional figures, musicians, and local residents, as well as documentation of rituals and architectural elements of the Siwaluh Jabu house. The findings reveal that music plays a significant role in each stage of construction, starting from the selection of suitable wood to the completion ritual known as Mengket. The Gendang Lima Sendalanen ensemble—particularly through the performance of Gendang Limapuluh Kurang Dua—functions as a medium connecting humans with ancestral spirits, legitimizing the spiritual presence within the house, and strengthening communal cooperation. Music serves not only to regulate the rhythm of collective work but also to ensure harmony between humans, nature, and the unseen forces that are believed to inhabit the house. Therefore, music is an essential element that maintains cultural continuity, reinforces identity, and supports the preservation of the Karo intangible heritage amidst ongoing modernization.

Maritime safety is a crucial aspect of sea transportation regulated by Law No. 17 of 2008, which mandates the fulfillment of ship seaworthiness and crew requirements. To ensure these standards are met, the Directorate General of Sea Transportation carries out continuous supervision through the issuance of the Ship Safety Certificate. This certificate ensures that the ship meets the material, construction, machinery, stability, and equipment requirements in accordance with regulations, including the SOLAS International Convention.

The results indicate that the certification process at KSOP Batam is in accordance with the applicable Standard Operating Procedures (SOP) and supported by the SIMKAPEL system. The study concludes that compliance with regulations and the utilization of digital systems are essential for maritime safety and efficiency.

This study examines the construction of reality and violations of broadcasting ethics in the Xpose Uncensored Trans7 program in 2025 which displays a negative image of pesantren and kiai. Using a descriptive qualitative approach with the framing analysis of Pan and Kosicki's model, this study reveals the existence of tendentious narrative and visual manipulation, thus giving the impression of harassment of religious symbols. The broadcasts are considered to violate the principles of balance and social responsibility as stipulated in the Broadcasting Code of Conduct and Broadcast Program Standards (P3SPS). The public reaction that emerged through the hashtag #BoikotTRANS7 reflects the increasing public awareness of the importance of ethics in broadcasting practices. This phenomenon shows that the media not only functions as a conveyor of information, but also has a moral responsibility in shaping public opinion in a fair and balanced manner. This study emphasizes the urgency of increasing media literacy and ethical sensitivity in the production of broadcast content, especially those related to the representation of religious groups. Thus, the results of this study are expected to be a reference for broadcasting institutions, media regulators, and the public in encouraging more ethical and responsible broadcasting practices in the digital era.

Farmers are grappling with drought challenges that jeopardize rice production. To address this, the government is promoting the use of water pumps and the construction of reservoirs. However, reservoir development comes with specific stipulations, such as the land used needing to be owned by the village or government. Climate change poses a significant challenge to Indonesia's agricultural sector. The pump irrigation program has emerged as a crucial solution for water scarcity in farmlands. This research was conducted in Belangturi Village, Ruteng District, Manggarai Regency, chosen purposively due to its status as a key rice paddy development area. The study took place from December 2023 to April 2024, employing simple random sampling. Data indicates there are 40 active rice paddy farmers in Belang Turi Village. An economic analysis forecasts substantial benefits from this program, including a 20-30% increase in rice production, an improved cropping index, crop diversification, and a 40-60% rise in farmer income. The financial analysis yields highly positive results: an NPV of IDR 450,000,000, an IRR of 18%, a Payback Period of 4.5 years, and a BCR of 1.75, all strongly indicating a highly feasible investment. From a social standpoint, pump irrigation is desperately needed and enthusiastically supported by the community. It's perceived as vital for overcoming critical water shortages, enhancing welfare, and improving access to education and healthcare. Therefore, implementing this pump irrigation system is highly recommended as a comprehensive solution for sustainable agricultural development in Belang Turi Village.

This research was conducted to evaluate the weld joint quality of V-groove and double V-groove configurations on ASTM A36 low carbon steel using the Self Shielded Flux-Cored Arc Welding (FCAW-SS) method. ASTM A36 was selected as the base material due to its favorable mechanical properties, excellent weldability, and wide application in construction and manufacturing. The welding process was carried out on steel plates with a thickness of 10 mm using E71T-1C wire, under controlled parameters of 140 A current, 24 V voltage, and 1G welding position. The weld quality was assessed through Dye Penetrant Testing (DPT), tensile testing, and bending testing. The Dye Penetrant Testing DPT results showed that the double V-groove joints exhibited fewer and smaller surface defects compared to the V-groove joints, indicating better weld homogeneity. Tensile testing demonstrated an average maximum strength of 277.645 MPa for the V-groove and 301.904 MPa for the double V-groove, reflecting an improvement of approximately 8.7% in the double V-groove. The bending tests revealed that the double V-groove joints were able to maintain structural integrity without significant cracks, while the V-groove joints tended to show defect indications under bending loads. Based on these findings, the double V-groove configuration is considered superior in terms of both strength and toughness, and therefore recommended for structural and manufacturing applications requiring high-quality joints in ASTM A36 low carbon steel.

In the development of a construction project, cost control is very important in the process of managing project costs. Many problems will be encountered in a construction project such as wasteful use of materials, unskilled labor and late completion of the project. This causes waste of costs that do not match the specified budget. In the construction project of the Rectorate of the Sorong City Health Polytechnic building, a budget of Rp. 36,570,996,788.55 is required. This study aims to make savings on previously planned costs, in addition to knowing the comparison of total project costs after analysis. The method used in this study is the Value Engineering method. The Value Engineering method is a method used to identify and eliminate unnecessary activities or reduce costs without reducing function. There are 4 stages of the work plan in this method, namely: Information Stage, Creative Stage, Analysis Stage, and Recommendation Stage. After conducting the Value Engineering analysis, savings of Rp. 654,875,786.25 or 1.79% of the total project cost were obtained. The analysis was conducted on the two highest-cost work items: wall and floor work. For the wall work, it was recommended that the HPL wall covering be replaced with plasterboard, while for the floor work, it was recommended that the 60x60 granite be replaced with 60x60 ceramic tiles.

The principle of proportionality plays an important role in ensuring a balance of rights and obligations between the parties to a reciprocal agreement. In the context of Indonesian contract law, this principle serves as a mechanism to prevent imbalances that could harm one of the parties, especially in commercial and complex contracts. This study uses a normative juridical approach with a literature review method, which involves analysis of relevant laws and regulations and case studies. This approach allows researchers to explore the application of the principle of proportionality in various types of reciprocal agreements, including franchise agreements and construction service contracts. For example, a study by Susanto et al. (2021) highlights how the principle of proportionality is applied in construction service contracts to ensure a fair distribution of responsibilities between contractors and clients. The results of the analysis show that the consistent application of the principle of proportionality can improve fairness in contractual relationships. In franchise agreements, the application of this principle helps to create a balance between the rights and obligations of the franchisor and franchisee, who often have different bargaining positions. Thus, the principle of proportionality serves not only as a legal principle, but also as a practical tool for achieving fairness in contractual practice

This research explores the dual impact of Artificial Intelligence (AI) on the academic writing experiences of English Literature students learning English as a Foreign Language (EFL). AI tools like ChatGPT, Grammarly, and QuillBot are commonly used for grammar correction and sentence construction. These tools are integrated into students' writing processes, providing valuable assistance in refining their written work. However, their psychological effects, particularly in terms of emotional and ethical implications, have not been sufficiently explored in previous research. This study employed a qualitative phenomenological approach, utilizing Interpretative Phenomenological Analysis (IPA), to examine the experiences of ten final-year EFL students who actively use AI tools for academic writing. Through semi-structured interviews, the research identified three major themes: reduced technical stress, heightened dependency on AI tools, and ethical concerns about authorship. The findings suggest that while AI tools act as cognitive scaffolds, aiding students by improving fluency and reducing the burden of technical writing tasks, they also introduce psychological challenges. These challenges include increased dependency on the tools and concerns about the authenticity of their work, raising questions about academic integrity and self-efficacy. This study sheds light on the complex relationship between AI as an assistive technology and its potential to cause writing anxiety and dependency. By emphasizing both the positive and negative psychological impacts of AI, the study contributes to the growing body of literature on AI in education. It calls for the development of pedagogical frameworks that balance AI literacy, emotional resilience, and ethical considerations to ensure responsible and effective use of AI in academic contexts.

This study aims to design a blanking die used for mass-producing mobile phone holders while prioritizing efficiency and dimensional accuracy. The die set developed includes key components such as the punch, die, stripper, guide post, and fastening bolts. The product produced has dimensions of 138 × 63 × 2 mm and uses ST 37 steel as the raw material. Based on calculations, the required blanking force is 129,000 kN, which is considered safe for the production process. The design also accounts for an optimal clearance of 0.083 mm and a die thickness of 35 mm to effectively withstand the working load. Simulations using stress analysis methods reveal that the von Mises stress distribution on both the punch and die remains below the elastic limit of SKD11 material. The maximum stress on the punch is recorded at 2.437 × 10⁵ N/m², while on the die it reaches 5.153 × 10⁵ N/m², both well below the yield strength of SKD11, which is 2.918 × 10⁸ N/m², indicating that these components operate safely without the risk of plastic deformation. To strengthen the construction, the stripper is designed with a thickness of 12 mm, and the addition of four SCM435 bolts is recommended to improve system stability. This die design is verified through manual calculations and Finite Element Analysis (FEA) to ensure its reliability. Overall, the findings of this study demonstrate that the designed blanking die can support mass production with high precision, optimal structural strength, and long-term durability.

This study examines the legal validity of direct appointment construction consultancy contracts between state-owned enterprises and their subsidiaries following the implementation of Indonesia's Job Creation Law. The research addresses critical questions regarding the formal legal mechanisms governing long-term unit-price framework agreements and their continued enforceability under amended procurement regulations. Employing a normative-jurisprudential methodology, the study systematically analyzes primary legal sources, including statutory provisions, government regulations, and corporate governance frameworks, alongside secondary legal materials and doctrinal commentaries. The analysis reveals that pre-Omnibus Law direct appointments complied with civil law contract validity requirements and sector-specific procurement regulations under Law No. 2/2017. Transitional provisions and the non-retroactivity principle preserved the enforceability of framework agreements executed prior to the Job Creation Law's enactment, while administrative amendments extending contract terms remained lawful under existing civil code provisions. The study demonstrates that direct appointment mechanisms achieve legal justification through constitutional mandates and legislative hierarchy, while providing utilitarian benefits through enhanced procurement efficiency and deployment of specialized technical expertise. The findings contribute to scholarly discourse on state-owned enterprise governance by elucidating how omnibus legislative reforms interact with contract doctrine and corporate governance norms, emphasizing the critical importance of robust conflict-of-interest safeguards in preventing procedural formalism from overshadowing substantive public interest outcomes.
