Plastic waste continues to be one of the most pressing environmental problems due to its persistence, excessive use in daily life, and difficulty in decomposition. In many communities, including Tanjung Uban Selatan Village, unmanaged plastic waste accumulates in the environment, contributing to pollution and health risks. This community service activity aims to introduce and implement ecobricks as a simple yet effective solution to manage plastic waste. Ecobricks are not designed to destroy plastic but to recycle and repurpose it into useful and even marketable products. The process of making ecobricks requires no special expertise or significant costs, as the primary material is household plastic waste. The activity involved socialization, practical workshops, and guidance for residents on how to properly produce ecobricks. Results from the program show that residents were able to collect and process previously unmanaged plastic waste into solid, reusable building blocks. These ecobricks have potential applications for creating furniture, decorative items, and even small-scale construction, thereby providing both environmental and economic value. Beyond reducing plastic waste, the initiative also fosters community awareness about sustainable waste management practices and promotes environmental responsibility. In conclusion, the introduction of ecobricks in Tanjung Uban Selatan Village demonstrates that simple innovations can empower communities to transform environmental challenges into opportunities for sustainability and income generation.

Plagiarism in scientific writing is a serious violation that not only harms the original creator but also undermines academic integrity, the development of scientific knowledge, and the credibility of educational institutions. This research aims to analyze the regulation of plagiarism acts based on the laws and regulations in Indonesia, as well as to build a firmer criminal law construction against acts of plagiarism within academic settings. This study employs a normative juridical method with a doctrinal approach, examining relevant laws and legal theories. The findings indicate that although plagiarism has been regulated in several legal instruments such as the Indonesian Penal Code (KUHP), Law Number 28 of 2014 on Copyright, Law Number 20 of 2003 on the National Education System, and the Regulation of the Minister of National Education Number 17 of 2010, the existing regulations tend to be administrative in nature and have not provided a sufficient deterrent effect. Therefore, a more comprehensive and implementable criminal law construction is needed to ensure the protection of scientific works and legal certainty in the enforcement of criminal sanctions against perpetrators of plagiarism. In addition, preventive efforts through academic ethics education, the implementation of plagiarism detection systems, and the strengthening of internal policies within universities are also important steps that must be optimized.

The increase in traffic volume in urban areas often triggers various problems, especially at Road intersection points that have a high level of interaction between vehicles. One of the locations that experience these problems is the intersection with the island of traffic without signal on Jl. Tebu-Jl. Tabrani Ahmad, City Of Pontianak. This study aims to analyze the performance of the intersection in the existing condition and project its performance in the next five years (2030), as well as formulate alternative treatment that can improve the smoothness of traffic. The analysis method refers to Indonesian road capacity guidelines (PKJI) 2023 and modeling using software PTV VISSIM. The data collected include intersection geometry, traffic volume, and vehicle speed. Traffic volumes were obtained through CCTV recordings for three consecutive days, then processed and presented in the form of tables and graphs for easy interpretation. The results of the existing condition analysis showed that the degree of saturation (DS) reached 0.407 with an average delay of 9.539 seconds (Level of Service/LOS B) based on PKJI, while VISSIM simulation resulted in a delay of 12.54 seconds (LOS B). The five-year projection (2030) shows an increase in DS to 0.878 with a delay of 15.177 seconds (LOS C) from PKJI, and 23.35 seconds (LOS C) from VISSIM, which indicates a decrease in Junction performance as traffic grows. Two handling alternatives were analyzed, namely the construction of roundabouts and the implementation of traffic flow management. VISSIM simulation shows that the roundabout can reduce the delay to 14.31 seconds with a queue length of 20.34 m (LOS B), while the flow management produces a delay of 11.81 seconds with a queue of 13.14 m (LOS B). This result confirms that both alternatives are able to improve the performance of the intersection compared to the projected condition without handling, so that it can be a technical recommendation for urban traffic planning in Pontianak.

This study proposes the integration of a Hybrid Recommendation method (combining Content-Based and Collaborative Filtering) with Random Forest Regression (RFR) to improve the accuracy of stay duration prediction in web-based boarding house booking systems. The main issue in online boarding booking systems is the inaccuracy of predicting user stay duration, affecting room allocation efficiency and customer satisfaction. The dataset was sourced from the hotel sector due to its attribute similarities and data validity. The research process includes data preprocessing (missing value imputation, normalization, and one-hot encoding), temporal and contextual feature engineering, hybrid recommendation system construction with CBF and CF score weighting, and RFR model training optimized through Grid Search and 10-fold cross-validation. Evaluation was conducted using MAE, RMSE, R² metrics, as well as recommendation metrics such as Precision@5, Recall@5, and Mean Reciprocal Rank (MRR). Results show that this integrated model achieved an R² of 0.7239 and an MAE of 1.0537 days, as well as a Precision@5 of 0.9636. This integration proves effective in improving prediction accuracy and recommendation relevance and contributes to the development of AI-based intelligent systems in the accommodation domain.

Oleh karena itu, perlu untuk ada tindakan tegas yang menyertai sifat wajib program yang digalangkan pemerintah seperti BPJS Ketenagakerjaan.

This study aims to integrate the Grounded Theory approach with James Spradley’s ethnographic method in hadith studies to understand the contextual meaning of hadiths within the social life of the community. The background of this research lies in the limitations of the classical hadith approach, which tends to focus only on textual aspects (sanad and matn) while lacking exploration of the underlying social and cultural meanings. Using a descriptive-analytical qualitative approach, the primary data are sourced from hadith collections such as Sahih Bukhari and Sahih Muslim, while the secondary data consist of literature on qualitative methodology, ethnography, and Grounded Theory. Data collection techniques were conducted through library research and analyzed using Spradley’s nine steps of ethnographic analysis, including domain analysis, taxonomic analysis, componential analysis, and theme analysis. The results indicate that the integration of these approaches enables the construction of thematic categories from hadiths based on the social experiences of the Muslim community and generates substantive theories relevant to the dynamics of Muslim social life. This approach not only broadens the understanding of hadith texts but also emphasizes the importance of viewing hadiths as social constructions embedded within Islamic culture.

In manufacturing industries, machining processes play a critical role in ensuring product quality, precision, and production efficiency. However, in the production of swing arm parts, the machining process has been identified as a bottleneck due to its non-optimal cycle time. One of the main issues contributing to this inefficiency is the disorganized handling of circlip inner parts. These components are often scattered without a designated placement system, which creates significant difficulties for operators when retrieving and installing circlips onto the swing arm. Such abnormalities disrupt workflow continuity, extend production time, and reduce overall productivity. To address this challenge, a circlip feeder machine was designed as a supporting device to assist operators and streamline the machining process. The design emphasizes efficiency, integration, and systematic operation by utilizing readily available workshop materials. The developed feeder machine is equipped with a robust frame construction and has a storage dimension capable of accommodating up to 200 circlips. In addition, mechanical analysis demonstrates that the feeder structure can withstand a maximum applied force of 31,475 N, ensuring durability and reliability during operation. The introduction of this circlip feeder machine directly impacts the production process by reducing operator workload, minimizing delays caused by disorganized parts, and ensuring faster and more accurate installation of circlips. Consequently, the overall machining cycle time is shortened, thereby improving production flow and enhancing the efficiency of swing arm part manufacturing. Beyond immediate time savings, the use of the feeder machine contributes to better resource utilization, reduced ergonomic strain on operators, and improved consistency in product quality. This study highlights the significance of simple yet effective mechanical innovations in overcoming production bottlenecks and optimizing manufacturing processes in automotive component industries.

This study analyzes Kompas.com’s news coverage of the Papua conflict and human rights issues during the 2024 Presidential Debate to examine media neutrality through Norman Fairclough’s Critical Discourse Analysis (CDA) integrated with Teun A. Van Dijk’s model. The analysis covers three dimensions: micro (text), meso (discursive practice), and macro (social practice), using a qualitative descriptive method. Data from 21 news excerpts reveal that social and political contexts are clearly represented, focusing on the strategies of the three presidential candidates in addressing human rights and conflict issues in Papua. The findings highlight the importance of realizing the Papua-related commitments made during the debate by the elected president, given the rising trend of violence and the unresolved justice issues in the region. The study demonstrates that media coverage, even by a leading news outlet such as Kompas.com, carries the potential to influence public perception regarding sensitive political and social issues. At the micro level, the language and lexical choices in the news articles often convey subtle ideological positions, including the framing of human rights violations and conflict events, which may reflect both explicit and implicit biases. At the meso level, discursive practices, including editorial decisions, headline constructions, and sourcing patterns, contribute to the shaping of narratives, highlighting certain aspects of the candidates’ statements while minimizing others. Meanwhile, at the macro level, the broader societal and political context, including historical grievances, regional tensions, and national political dynamics, provides the backdrop against which news coverage is produced and consumed, indicating the complex interplay between 

This research is motivated by the lack of interesting learning media that can motivate and facilitate students in understanding fashion design material. The purpose of this research is to develop Pop-Up Book Fashion media as an innovative and interactive learning tool and to determine the feasibility of Pop-Up Book Fashion media on the material of custom skirts. The research method used is development research with a 4D model with stages consisting of 4 main stages, namely: (1) Define (Definition) (2) Design (Planning); (3) Develop (Development); (4) Disseminate (Dissemination). Assessment of product feasibility results is carried out by validation to 1 validator, namely a media expert. There is 1 more validator, namely the validator of the student response questionnaire instrument. Based on the value of the validator regarding the results of the product feasibility, the average score from the media expert is 91% (very feasible). Trials on 18 class X students of SMK Negeri 6 Surabaya showed an interest level of 91.11% (very interesting). So it can be concluded that the Pop up book Fashion media is proven to be effective and interesting to use as a learning medium. This media is recommended as an innovative alternative to improve student learning outcomes, particularly in fashion design. In addition to enhancing students' understanding of fashion design materials, the use of Pop-Up Book Fashion media also provides a stronger visual and kinesthetic learning experience. Through direct interaction with media that can be touched and moved, students can imagine the final form of clothing more realistically, especially for the custom skirt material that requires visualization of models and construction. This media not only helps with cognitive aspects but also facilitates students' emotional engagement in the learning process. This is in line with the thematic learning approach that emphasizes the importance of multisensory engagement in increasing retention and learning interest.

The Community Service Program (KKN) was implemented with the aim of improving service and security at the Class IIB Tebing Tinggi Correctional Institution (Lapas) through a simple yet functional innovation in the form of a two-function suggestion box. This suggestion box was designed with two separate channels to accommodate aspirations from two separate sections, namely Bimbingan Narapidana/Anak Didik and Security, to facilitate the delivery of input in a safe, structured, and confidential manner. The implementation method of the activity included initial observation, identification of needs, design and construction of the box, and the socialization stage of its use. The results of this activity showed an increase in inmate participation in providing constructive suggestions and the creation of a more open communication channel without disrupting security stability. This innovation is one form of real contribution of cadets in supporting bureaucratic reform and more humane guidance in the correctional environment.

This study investigates the potential of Low-Density Polyethylene (LDPE) plastic waste as a partial substitute for sand in concrete block mixtures, focusing on its effects on compressive strength and water absorption. LDPE is a non-biodegradable plastic waste that poses significant environmental challenges. Its incorporation into construction materials offers a promising solution to reduce pollution while enhancing the performance of building components. The research employed LDPE substitution levels of 10%, 15%, 20%, 25%, and 30% by weight of sand, compared against conventional concrete blocks without LDPE. Experimental results revealed that the highest compressive strength was achieved with a 15% LDPE mixture, reaching 80.762 kg/cm² at 28 days of curing—an increase of approximately 40.8% compared to normal blocks, which recorded 57.359 kg/cm². LDPE additions up to 20% maintained favorable strength characteristics, while higher proportions (25% and 30%) led to a decline in mechanical performance. In terms of water absorption, the inclusion of LDPE demonstrated a decreasing trend, attributed to the hydrophobic nature of plastic, which enhances moisture resistance in the concrete blocks. These findings suggest that a 15% LDPE substitution represents an optimal formulation for producing eco-friendly concrete blocks with improved strength and reduced water absorption. The study highlights the dual benefits of waste management and material innovation, aligning with sustainable development goals. By repurposing plastic waste into construction applications, this approach not only mitigates environmental impact but also contributes to the advancement of green building technologies. Further research is recommended to explore long-term durability, thermal properties, and scalability of LDPE-based concrete products in real-world construction settings.

This study aims to analyze how internal strategies and external challenges can influence the achievement of Regional Original Revenue targets at the Laboratory Technical Implementation Unit (UPTD) of the Public Works and Public Housing Agency (Dinas Pekerjaan Umum dan Perumahan Rakyat) of Cilacap Regency. The research object is the performance of the Laboratory Technical Implementation Unit (UPTD), a technical unit providing construction material testing services, which directly contributes to Regional Original Revenue in Cilacap Regency. The qualitative approach employed a case study method, and data collection techniques included interviews, observation, and documentation. The sample in this study was obtained purposively. The results indicate that internal strategies focused on superior testing methods such as core drilling, abrasion, and concrete compressive strength have been conducted. However, limited equipment, human resources, and the lack of accreditation are major obstacles. On the other hand, external challenges include the lack of updated Regional Regulation tariff regulations, the absence of formal obligations for the use of laboratory services for regional budget projects, and a saturated local market. These findings provide important implications for the Laboratory Technical Implementation Unit (UPTD) in emphasizing policy revisions, increasing internal capacity, and strengthening inter-agency coordination to increase Regional Original Revenue realization.

Rural economic development in underdeveloped areas requires a strategic approach that integrates local potential, agricultural infrastructure, and appropriate technology (AT) to foster inclusive and sustainable growth. This study aims to analyze rural economic development strategies through a literature review and thematic synthesis of relevant studies. The findings reveal that optimizing local potential, such as natural and socio-cultural village resources, can enhance community economic self-reliance. Strengthening agricultural infrastructure, especially the construction of farm roads, significantly improves distribution efficiency and farmer income. The application of appropriate technology in agriculture, small enterprises, education, and healthcare further accelerates economic and social transformation in rural areas. Nevertheless, challenges such as limited basic infrastructure, digital gaps, and low technological literacy require collaborative solutions. Therefore, development strategies based on local potential, functional infrastructure, and technological innovation are essential to building independent, productive, and competitive rural communities.

The Public-Private Partnership (PPP) scheme with guarantees from PT PII aims to accelerate infrastructure development through private participation, but faces legal and practical challenges, particularly related to the risk of default by the Government and Construction Service Provider (GCA) and the effectiveness of the implementation of recourse rights by PT PII towards government institutions. This study uses a normative juridical method with an analytical descriptive approach through a literature study of primary and secondary legal materials, as well as a qualitative analysis of legal documents, to understand in depth the application of recourse rights to GCA in the PPP mechanism. The application of recourse rights by PT PII as a PPP project guarantor is based on a special legal framework and complex contractual agreements to protect investors from the risk of default by the GCA. However, its implementation has the potential to face legal, political, bureaucratic, and fiscal challenges that can affect the effectiveness of protection and the fiscal sustainability of PT PII. PT PII's recourse rights in the PPP scheme are an adaptation of the borgtocht concept applied lex specialis through the PPP agreement, guarantees, and recourse to protect state finances. However, its implementation faces bureaucratic, budgetary, and fiscal constraints that can hamper its effectiveness. Therefore, binding guidelines and increased institutional capacity are needed to ensure that regress rights can be exercised effectively, accountably, and in accordance with the principles of transparency and accountability. This study concludes that to increase the effectiveness of the PPP scheme, improvements in the legal framework, inter-agency coordination, and strengthening the capacity of institutions involved in implementing regress rights are needed.

Subcontractor selection is a crucial factor in determining the success of a construction project. The selected subcontractor not only plays a role in expediting the completion of the work but also influences the overall quality, cost, and timeliness of the project. Mistakes in decision-making, such as selecting a less competent subcontractor, can result in delays in completion, increased project costs, and even decreased construction quality. Therefore, a systematic, measurable, and objective method is needed to support the subcontractor selection process. This study aims to implement the Analytical Hierarchy Process (AHP) method as an approach in a decision support system for subcontractor selection. AHP was chosen because it can decompose complex problems into simpler structures by determining criteria weights and comparing alternatives. The criteria used in this study include expertise, work experience, timeliness of work, equipment availability, and bid price. By assigning weights to each criterion, the selection process can be carried out more transparently and measurably. The case study was conducted at PT. Tatha Group, a company engaged in the construction services sector. In this study, AHP was used to prioritize alternative subcontractors to be selected to assist in project implementation. The research results show that the AHP method produces clear, structured results and supports more accurate decision-making. Thus, the application of AHP not only minimizes subjectivity in assessments but also provides accountable recommendations for selecting the best subcontractor for the project's needs.

Understanding verb-noun collocations is essential for exploring how abstract personal qualities are represented in language. This study aims to find out the types of verbs that occur before the five self-related compound nouns (self-esteem, self-confidence, self-assurance, self-worth, and self-respect), and investigate their collocational patterns. The data in this study were obtained from the Corpus of Contemporary American English (COCA). The data were collected by applying the documentation method. The technique involved searching for five compound nouns within the corpus and recording instances of their use. These occurrences, along with their collocates, were then copied and organized in an Excel spreadsheet. In the spreadsheet, columns were adjusted to separate and classify key elements such as the compound noun, the collocating verb, frequency data, and context sentences. The collected data were analyzed qualitatively to provide insights into lexical patterns, the types and tokens of frequency. The results show that the verbs that collocate with five self-related compounds in COCA vary in number and frequency, with self-confidence showing the highest types (20) and self-assurance the lowest (9). The verb build appears most frequently with self-confidence and self-esteem (4 tokens each), suggesting both are viewed as qualities that can be constructed or improved. Self-respect predominantly collocates with have (4 tokens), implying it is seen as possessive, while self-worth reflects both positive and negative framing through increase and reduce (2 tokens each). In contrast, self-assurance is frequently associated with lack (4 tokens) and show (2 tokens), indicating its absence or visibility. These patterns reveal that verb collocates offer important insights into how language frames self-constructions.

The contractual relationship between government entities (PA/KPA/PPK) and construction service providers in procurement activities is complex, as it intersects with both public and private law. Government procurement contracts for construction projects are often structured through a tender process, where service providers must compete to win the contract. Once the provider is selected, a legal agreement is formed, which regulates the roles, responsibilities, and obligations of the parties involved. This agreement is typically outlined in a contract document that serves as a formal, legally binding commitment. In civil law, such contracts are typically governed by private law principles, which include contracts, obligations, and liabilities. However, the nature of government procurement contracts adds a unique element of public law, particularly administrative and criminal law. The government’s involvement in these contracts introduces a dual legal framework that governs the relationship between the parties. On one hand, the contract is influenced by the state’s regulatory powers and administrative authority, ensuring compliance with legal standards and public interests. On the other hand, it is also subject to private law principles, as the government enters into agreements with construction providers just like any other business transaction. This mixed legal framework (or "mixed law") creates a distinctive legal relationship, where elements of public law, such as administrative regulations and oversight, coexist with private law principles, such as those governing contract enforcement and dispute resolution. The contract, which is a Keputusan Tindakan Administrasi Negara (KTUN), remains a civil law act, despite its public law foundation. This hybrid nature of government contracts ensures that both public and private law aspects are considered in the process, which can sometimes lead to legal complexities and challenges in the implementation and enforcement of these contracts.
