This study aims to forecast beef prices in Palembang City and at the national level in Indonesia using the Autoregressive Integrated Moving Average (ARIMA) method. The data used are the monthly average beef prices for the period January 2019 to December 2024. The analysis involves stationarity tests using Augmented Dickey-Fuller (ADF), model identification through Autocorrelation Function (ACF) and Partial Autocorrelation Function (PACF) plots, parameter estimation with Maximum Likelihood Estimation (MLE), and residual diagnostics with the Ljung-Box and Jarque-Bera tests. The results show that beef prices at both regional levels are not stationary at the level but become stationary after the first differencing (I(1)). The best ARIMA models obtained are ARIMA(0,1,1) for Palembang City and ARIMA(1,1,0) for the national level. Both models successfully predict price fluctuations with a low error rate and show a moderate price increase trend. These findings provide practical implications for price stabilization policy making and beef-related business planning. The forecast results state that beef prices in Palembang City and nationally are predicted to tend to rise in 2025 from January to December.  

This community service program was carried out to strengthen the ability of lecturers, students, and practitioners in understanding the role of data and statistics as the foundation for constructing scientific arguments in quantitative research. The activity originated from the limited understanding of some participants regarding the correct logical flow of research, starting from problem formulation, hypothesis development, data processing, to drawing conclusions based on analytical results. Through case-based training and interactive discussions, participants were introduced to key concepts in research methodology, such as determining variables, sampling techniques, developing measurement instruments, and applying parametric and non-parametric statistics to test hypotheses. The training emphasized that data provide factual descriptions of a phenomenon, while statistics serve as analytical tools that answer research questions objectively. The activity was conducted online with 73 participants from Universitas Pancasakti Bekasi, representing various academic backgrounds. The results indicated an improvement in participants' ability to understand statistical outputs, interpret significance levels of tests, and prepare research conclusions in a logical and structured manner. In addition, the activity contributed to enhancing methodological literacy within the academic community, encouraging a strong research culture, and maximizing the use of statistics in scientific analysis as well as professional practice. Therefore, this program has a positive impact on improving the quality of research in higher education.

This study aims to analyze the effectiveness of the Family Hope Program (PKH) in alleviating poverty, with a case study focus on Sei Jang Village, Tanjungpinang City. PKH is a social assistance program initiated by the government to improve the welfare of the poor through conditional cash assistance. The reason the researcher chose this title was to determine the extent to which PKH is effective in reducing poverty, especially since data shows a decline in the number of PKH recipients in Sei Jang Village in 2023. This study uses a qualitative approach with a descriptive method, where data is obtained through in-depth interviews, observation, and documentation studies. To measure the level of effectiveness, the theory from (Makmur, 2015) was used, which states that the elements of effectiveness include accuracy in timing, accuracy in calculation, accuracy in measurement, accuracy in decision making, accuracy in thinking, accuracy in carrying out orders, accuracy in determining goals, and accuracy in targeting. The results of the study show that PKH has had a positive impact on reducing the economic burden on poor families, particularly in meeting the educational and health needs of children. However, the effectiveness of this program is still hampered by several factors, such as delays in fund disbursement, participants' lack of understanding of the program's terms and conditions, and minimal assistance from relevant officials. In addition, another challenge in the form of inaccuracy in targeting beneficiaries also affects the overall achievement of the program. These findings indicate that better management and supervision are urgently needed. This study concludes that although PKH contributes significantly to poverty alleviation, improvements in management and supervision are needed to maximize the program's objectives. The proposed recommendations include increasing the capacity of social workers, improving the beneficiary selection mechanism, and strengthening coordination among stakeholders at the local level.

Education has long been recognized as a primary determinant of economic progress and human development , yet in the context of a global economy characterized by rapid technological change and the sustainability imperative, the focus shifts from the mere quantity of investment to its effectiveness in fostering sustainable economic growth. Current education systems face significant challenges, including a persistent global "learning crisis" , governance inefficiencies , and a misalignment between curricula and the demands of the labor market, particularly the green and digital economies. Given that existing literature often treats education investment as a static input and fails to holistically integrate sustainability and governance into the optimization process , this conceptual article aims to bridge these theoretical and empirical gaps by proposing an integrated model for the optimization of education investment for sustainable economic growth. The method involves a conceptual analysis that synthesizes human capital theory , endogenous growth theory , and the economics of sustainability , emphasizing the roles of governance, innovation, and inclusivity as mediating factors. The key finding of the study indicates that optimization necessitates a paradigm shift from input-oriented budgeting toward an outcome-based investment framework that holistically balances three crucial dimensions: efficiency (maximizing learning outcomes) , equity (ensuring inclusive access) , and relevance (alignment with sustainability needs). The resulting policy implications are delineated across the Macro (fiscal integration and sustainability strategies through performance-based funding) , Meso (institutions transform into adaptive innovation centers) , and Micro (enhancement of reskilling, upskilling, and human capital capacity) levels; by achieving this alignment, education successfully transitions from a cost center to a strategic catalyst driving sustained prosperity.    

This study aims to analyze the implementation gap (Das Sein) against the normative provisions (Das Sollen) regarding the prohibition on riding a motorbike with more than one passenger (Bonceng Tiga/BOTI) as regulated in Article 106 Paragraph (9) of Law Number 22 of 2009 concerning Traffic and Road Transportation (LLAJ Law). The main problems studied are the factors underlying public non-compliance and the effectiveness of the role of the authorities in implementing criminal sanctions in the form of fines in Article 292 of the LLAJ Law. This study uses a normative legal research method with a statute approach and a conceptual approach. The secondary data analyzed are in the form of primary legal materials (LLAJ Law) and secondary (journals, books, study results). The results of the initial study indicate a significant gap between the prohibition norm (Das Sollen) and practice in the field (Das Sein). Public non-compliance is influenced by socio-economic factors (wanting to save time and costs), while the effectiveness of the maximum fine of IDR 250,000.00 (Article 292) is considered low because the nominal value does not create an adequate deterrent effect. In addition, inconsistent law enforcement also exacerbates ineffectiveness. Therefore, a revision of the legal substance and an increase in enforcement consistency are needed to optimize traffic safety guarantees.

This study examines the role of the Pustaka Prima Community Reading Park (TBM) as an alternative learning space that provides non-formal educational experiences for children and adolescents, especially in communities with limited access to educational facilities. Through a descriptive qualitative approach, this study explores the contribution of TBM in developing creativity, literacy skills, self-expression, and independent learning of participants. Data was collected through participant observations, semi-structured interviews with managers and participants, and documentation of program activities. The results of the study show that TBM Pustaka Prima plays a significant role in strengthening cognitive, social, and emotional development through various activities such as reading literacy, storytelling, basic entrepreneurship training, and other creative activities. These programs have been proven to increase reading motivation, the ability to understand texts, confidence in communication, technology awareness, and the ability to innovate. An inclusive and collaborative learning environment allows participants to explore knowledge, work together, and optimize their potential. These findings confirm that TBM not only functions as a provider of reading materials, but also as a community-based education center that provides meaningful learning experiences outside the formal education system. The implications of the research emphasize the importance of strengthening collaboration, developing sustainable programs, and improving resources and infrastructure to maximize the role of TBM in community empowerment.

Driven by the need for sustainable building materials with effective acoustic performance, this work investigates coconut-fiber-based cement-bonded particleboard as a bio-based alternative, evaluating its sound absorption and transmission characteristics to determine suitability for noise control in architectural and industrial applications while considering manufacturability, local material availability, and potential environmental benefits compared to conventional synthetic panels and providing guidance for designers and manufacturers across different climatic zones. This study aims to analyze the acoustic characteristics of coconut-fiber-based Cement-Bonded Particleboard (CBPB) through measurements of the Sound Absorption Coefficient (SAC, α) and Transmission Loss (TL). CBPB samples were fabricated with thickness variations of 12, 16, and 20 mm and tested using an impedance tube in accordance with ISO 10534-2:1998 and the ASTM E90-09 (2016) method. The results showed that the α value increased with both frequency and panel thickness, reaching a maximum of 0.78 at frequencies of 2500–3150 Hz for the 20 mm panel. The highest TL value reached 42 dB at a frequency of 4000 Hz. Coconut-fiber-based CBPB demonstrated strong potential as an eco-friendly structural acoustic material.

Indonesia’s rich religious, ethnic, and cultural diversity has long been accompanied by challenges related to socio-religious conflict. One important yet often overlooked dimension is intra-religious tension, illustrated by the differing perspectives of Nahdlatul Ulama (NU) and Muhammadiyah—the two largest Islamic organizations in the country. This study examines how these organizations manage their doctrinal differences (khilafiyah) and uphold tolerance as an expression of the First Principle of Pancasila. Using a qualitative literature review, the research analyzes organizational documents, scholarly works, and academic articles concerning both groups. Findings show that their divergence stems primarily from distinct methodological frameworks. NU follows the Aswaja tradition, accommodating local culture through the concept of Islam Nusantara, adhering to classical jurisprudential schools, and applying the maxim al-muhafadzah. In contrast, Muhammadiyah employs the Manhaj Tarjih and a Tajdid (renewal) approach centered on purification and modernization, forming the basis of its Progressive Islam vision. Despite differences in jurisprudential practice, both organizations share a commitment to moderation (wasathiyyah). NU expresses tolerance through its principles of Tawassuth, Tawazun, Tasamuh, and the Trilogy of Brotherhood, whereas Muhammadiyah emphasizes justice and respect for diversity in its Guidelines for Islamic Life. Their mutual acceptance of Pancasila—as Darul Ahdi wa Syahadah for Muhammadiyah and the foundation of Ukhuwah Wathaniyah for NU—demonstrates that internal Islamic pluralism can strengthen, rather than weaken, national unity.

Negative Binomial Regression is a statistical modeling approach used to analyze count data with overdispersion, where the variance exceeds the mean. This study applies the method to examine the influence of weather factors on the daily number of cyclists crossing the Williamsburg Bridge in New York City. The independent variables used in the analysis include maximum temperature, minimum temperature, and precipitation. The dataset was obtained from the NYC Department of Transportation through the Kaggle platform and covers the period from April 1 to April 30, 2016. The analysis began with a Poisson Regression model; however, the presence of overdispersion was identified, indicated by a high AIC value of 8598.19, suggesting that the model was not suitable. The alternative Negative Binomial Regression model was then employed and produced a significantly lower AIC value of 518.77, demonstrating a superior fit. The findings indicate that maximum temperature has a positive effect on the number of cyclists, while precipitation shows a significant negative effect. Conversely, minimum temperature does not exhibit a meaningful influence. These results highlight the importance of considering weather conditions when planning bicycle-based transportation systems and support the development of sustainable mobility strategies in urban environments.

In the fast-moving fashion retail industry, supply chain efficiency is a key factor in operational success. Heybeb Factory Outlet, as one of the retail business actors, faces challenges in managing the flow of goods from upstream to downstream, particularly in balancing demand between offline (physical stores) and online (e-commerce/marketplace) channels. This proposal aims to design and analyze the logistics workflow starting from goods ordering (restocking) from the central warehouse, the goods receiving process, rigorous Quality Control (QC) procedures, storage in a dedicated transit warehouse, and the stock distribution mechanism (stock split) for the two sales channels. The main issues identified include the risk of overselling in one channel while stock accumulation occurs in another, as well as the potential for defective items to pass through due to an unstructured QC process. This study employs a descriptive qualitative approach by mapping out an ideal Standard Operating Procedure (SOP). The expected outcome is the development of an integrated inventory management system capable of minimizing return rates caused by defective items and maximizing inventory turnover through accurate stock allocation between online and offline divisions.

The location of MAN 4 Pekanbaru City on Jalan Yos Sudarso, one of the routes with a fairly high intensity of large vehicle activity, demands the availability of transportation services that can provide certainty of time, comfort, and safety for students. In this context, the existence of online motorcycle taxis is a relevant transportation alternative in today's digital era. This study uses a descriptive qualitative approach with the aim of describing in depth the experiences, perceptions, and assessments of students' assessments of the quality of Maxim online motorcycle taxi services. Data collection techniques were carried out through interviews with several students of MAN 4 Pekanbaru City who actively use the service in their daily activities, especially for going to and from school. The results of the study indicate that Maxim online motorcycle taxi services are considered quite effective in supporting student mobility, especially in terms of ease of access, time efficiency, and relatively affordable costs compared to other modes of transportation. In addition, the use of digital-based applications provides ease in ordering and transparency of fares. However, the aspects of safety and comfort remain a primary concern for students. Therefore, it is recommended that students use official online motorcycle taxi (ojek) applications to minimize the risk of fraud and other undesirable incidents. Overall, the Maxim online motorcycle taxi service serves as a transportation solution that supports students' mobility needs in urban environments.

This study explores the implementation of e-Government within the context of Bawaslu (Election Supervisory Agency) and its impact on governance and public trust. The results reveal that, from the support aspect, the success of e-Government implementation is largely driven by the commitment of leadership, which provides essential policies, human resources (HR) training, and technological facilities. However, challenges remain in terms of limited infrastructure and budget constraints at the district and city levels. Regarding the capacity aspect, Bawaslu already possesses competent HR, particularly among the younger generation, and adequate infrastructure. Nevertheless, there is still a need for improvement in the distribution of employee capabilities through continuous training and mentoring. Lastly, from the value perspective, e-Government has proven to deliver tangible benefits, such as increased efficiency, transparency, accountability, and an enhanced public trust in the institution. However, further efforts are required in areas such as system socialization, maintenance, and data security to maximize these benefits. This research highlights the importance of continuous development in both human and technological resources to ensure the optimal success of e-Government initiatives in enhancing governance and service delivery.

Legal certainty (rechtssicherheit) is a fundamental pillar of the rule of law, ensuring that legal provisions are clear, consistent, and predictable. In the Indonesian criminal justice system, the Public Prosecutor holds a central position as the Dominus Litis (the owner of the case), determining which cases proceed to court. However, the implementation of prosecutorial authority often leans towards rigid legal positivism, creating a paradox where procedural certainty is achieved at the expense of substantive justice. Disparities in prosecution demands for similar crimes often lead to public distrust and legal uncertainty for justice seekers. This study aims to analyze the challenges in maintaining legal certainty and proposes a strategy to enhance the prosecutor's role through the integration of Restorative Justice and professional discretion. The research employs a normative juridical method with statutory and conceptual approaches, analyzing Attorney General Regulation No. 15 of 2020. The study finds that enhancing legal certainty requires shifting the paradigm from "mechanical prosecution" to "discretionary prosecution" based on conscience. To achieve this, prosecutors must be equipped with high-level cognitive skills to interpret "certainty" not just as textual compliance, but as the consistent application of fairness.

Corruption in Indonesia is not merely a moral transgression but an extraordinary economic crime that depletes national resources. The ultimate objective of corruption eradication, therefore, must be the restoration of state financial losses (asset recovery).  However, the current formulation of the criminal law system specifically Article 18 of Law No. 31 of 1999 contains a critical policy flaw. The provision of "Subsidiary Imprisonment" (Pidana Pengganti) allows convicts to substitute their financial restitution obligations with a disproportionately short prison term. This mechanism inadvertently provides an economic incentive for corruptors to conceal assets and choose imprisonment, resulting in significant state revenue loss. This study aims to critique the current penal policy formulation and propose a comprehensive reformulation of the compensation system. The research employs a normative-juridical method with a statutory and conceptual approach, utilizing the "Economic Analysis of Law" theory to evaluate the efficiency of sanctions. The study argues that the penal policy must shift from a "person-based" approach (in personam) to an "asset-based" approach (in rem). It is imperative to abolish the subsidiary imprisonment option for high-value corruption and implement "Non-Conviction Based Forfeiture" to maximize the recovery of state losses. Furthermore, this policy shift requires law enforcers with high-level cognitive skills to trace complex financial trails.

This literature review examines the effectiveness of planning history learning based on the Problem Based Learning (PBL) model in developing students critical thinking skills. The study is motivated by the persistent dominance of teacher-centered instruction in history classes, which limits students analytical and reflective engagement with historical issues. This research aims to analyze how structured PBL, based lesson planning especially in designing problems, learning activities, media, and evaluation tools. Can enhance critical historical reasoning. Using a qualitative descriptive method through a review of journal articles, books, and research reports, the study finds that effective PBL planning requires identifying authentic historical problems, organizing collaborative inquiry activities, providing adequate scaffolding, and using critical thinking oriented evaluation rubrics. The results show that PBL consistently improves students’ analytical, evaluative, and interpretive abilities when supported by systematic planning and sufficient learning resources. The study implies that teachers must strengthen the planning phase, particularly in preparing learning scenarios and assessment instruments, to maximize the impact of PBL on critical thinking development.

This study formulates a design concept for the Beach Tourism Resort Area in Botubarani Village by applying tropical architecture that responds to coastal climatic conditions while enhancing the quality of visitor experiences. The research integrates principles of thermal comfort, environmental sustainability, and the ecological potential of coastal environments as the basis for creating climate-adaptive and environmentally responsive tourism areas. The methodology includes site analysis, field observation, climatological assessment, and a literature review related to tropical architecture and coastal tourism design. The collected data were used to determine building orientation, mass layout patterns, visitor capacity, materials, vegetation, and utility systems appropriate for humid tropical climates. The findings show that the site’s position between the sea and the mountains, combined with full-day sun exposure, requires design strategies that maximize cross-ventilation, utilize sloped roofs, provide natural shading, and apply local materials such as wood, bamboo, and red brick. The large spatial needs based on visitor capacity projections are accommodated through a flexible cluster layout that supports visual and functional connectivity between buildings while incorporating green open spaces to enhance microclimate comfort. The utility system is designed using sustainability principles through greywater–blackwater separation, infiltration wells, and recycling-based waste management. This study confirms that the application of tropical architecture in coastal tourism areas can improve thermal comfort, energy efficiency, and environmental sustainability. These findings guide developing tropical tourism area designs that are more adaptive to climate change and more responsive to visitor needs.

Micro-Hydro Power Plant (MHPP) is a renewable energy solution suitable for remote rural areas with river flow availability. This study was carried out in Kampung 17, Batulawang Village, West Java, through the Community Service Program of HMM ITPLN, by designing and implementing a simplified MHPP system. The analysis indicates a hydraulic power potential of 1.511 kW with an effective head of 3.08 m and a discharge of 0.005 m³/s. Of this potential, the maximum utilized power reached 1.108 kW, equivalent to 73.32% of hydraulic energy utilization. The system is capable of producing approximately 26.6 kWh per day or around 798 kWh per month, matching the total demand of 12 households and one mosque in Kampung 17. If this demand were supplied by the national grid (PLN) under the R-1/TR 1300 VA category at Rp1,444.70 per kWh, the monthly cost would amount to approximately Rp1,152,870. Hence, the MHPP enables annual savings of around Rp13.8 million while ensuring local energy independence

The employee leave application information system is a digital solution designed to simplify the process of submitting, approving, and managing leave within an institution. This internship project resulted in the development of a system called SiCuti, which was built using the Laravel framework with a MySQL database. The system provides two main roles: employees and administrators/supervisors. Employees can apply for leave according to their entitlements, such as annual leave with a maximum of 12 working days, maternity leave for 3 months, pilgrimage leave (Hajj) which can be taken once during their service period, as well as special leave for important reasons such as marriage or the death of an immediate family member, typically lasting 1–3 days. When applying, employees may also upload supporting documents and monitor the status of their applications through the leave status menu.Administrators or supervisors have broader authority, including reviewing the list of leave requests, approving or rejecting applications, and managing employee leave quotas to ensure compliance with regulations. In addition, administrators can track the complete leave history of employees through an integrated dashboard. This feature supports faster, more transparent, and accountable decision-making processes.The results of local testing indicate that SiCuti has the potential to increase efficiency in administrative leave processes that were previously carried out manually, making them faster, more transparent, and more structured. The interactive dashboard design also facilitates monitoring from both employees and administrators. With the implementation of SiCuti, it is expected that the leave management process can reduce the risk of human error, ensure data accuracy, and support transparency and accountability in human resource management once the system is fully deployed within the institution.
