Office management is a key component in ensuring the effectiveness and efficiency of administrative services in both public and educational institutions. The increasing demands for service speed, accuracy, transparency, and professionalism necessitate an integrated and adaptive office management system. This study aims to explore how office management contributes to enhancing administrative service quality through a library research approach. Data were obtained from academic journals, theses, institutional reports, and theoretical literature. The analysis reveals that effective office management encompasses structured planning, proper document management, digital information systems, and staff competency development, all of which contribute significantly to improved service quality. Moreover, standard operating procedures and the integration of manual and digital systems enhance consistency and service reliability. The study supports the theoretical proposition that office management functions planning, organizing, actuating, and controlling are directly correlated with administrative performance indicators. Practical implications include the urgency of digitizing records, implementing standardized workflows, and continuously training administrative personnel. Limitations of this research lie in its purely conceptual and literature-based nature, thus future studies are recommended to adopt empirical or mixed methods approaches for broader generalizability. These findings reaffirm the importance of repositioning office management from a support function to a strategic pillar in administrative service improvement efforts.

Tourism is a sector that contributes significantly to economic growth in Bangka Belitung. This article explores the level of visitor satisfaction as a key indicator in improving the competitiveness of the tourism sector in this region. This study applies a mixed approach, combining quantitative methods to gain in-depth insights into the factors that influence visitor satisfaction. Through a survey involving 100 respondents who visited various destinations in Bangka Belitung, the results show that service quality, natural beauty, and adequate facilities have a positive effect on tourist satisfaction. High satisfaction not only encourages tourists to return, but also increases word-of-mouth recommendations, which are very important in tourism marketing. In addition, with increased satisfaction, the competitiveness of tourism in this area is also raised, making it more attractive compared to other destinations. This study recommends that tourism managers focus on improving service quality, infrastructure development, and ongoing promotion to attract more tourists. Thus, tourist satisfaction is not only a goal, but also an important strategy in strengthening Bangka Belitung's position as a competitive tourist destination.

This study explores the influence of social interactions in the school environment on the emotional development of fifth-grade students at SDN 060875 Medan. Using an explanatory sequential mixed-methods design (30 participants), data were collected through participatory observation, emotional intelligence scales (EIK), and interviews. Results revealed a significant positive correlation between social interaction and emotional regulation (r = 0.62; p < 0.05). Cooperative interactions (65% of total interactions) and partner diversity were critical for developing empathy and self-awareness. Teachers functioned as emotional models through emotion coaching techniques, while a mastery goal-oriented classroom climate strengthened this relationship. Practical implications include integrating social-emotional learning (SEL) into cross-group collaborative activities and structured peer mentoring programs. This research affirms social interaction as a constitutive foundation for emotional development in Indonesia’s socio-cultural context.

Coastal environmental pollution is an increasingly complex problem in Indonesia, especially due to uncontrolled waste disposal. This study aims to analyze the impact of waste disposal on the environment in the coastal area of Putra Deli Beach, Deli Serdang Regency. The research approach used is mixed-method with data collection through direct observation, semi-structured interviews, and literature study. The results showed that plastic waste dominates the types of waste found at the research site and is the main cause of marine ecosystem pollution. The impacts include damage to marine biota habitat, decreased tourist attraction, public health problems, and economic losses for local businesses. The lack of waste management facilities and low environmental awareness also exacerbate this condition. Therefore, an integrated waste management strategy based on community and stakeholder collaboration is needed to maintain the sustainability of the coastal environment.

Limited land in the urban area of Jayapura Regency is a major challenge in the provision of Green Open Space (RTH), even though the existence of RTH is very important to maintain ecological balance and the quality of the community's living environment. In this context, the Dosay Public Cemetery (TPU) has great potential to be optimized as an alternative green space that is multifunctional-ecological, social, and aesthetic. This study aims to assess community perceptions of the utilization of TPU Dosay as a green space, as well as to formulate a strategy for its sustainable development. The approach used was mixed methods, with data collection through a survey using a Likert scale to 35 respondents, open interviews with 9 key informants, as well as SWOT and AHP analysis. The results showed that most people support the development of TPU Dosay as a reflective green space that is comfortable and ecologically valuable. From the results of AHP analysis, policy and regulation aspects are the top priorities in the development strategy, followed by vegetation and accessibility aspects. Strategic recommendations include the preparation of adaptive vegetation zoning, strengthening the local policy framework, active involvement of indigenous communities, and cross-sector collaboration between local governments, academics and the private sector. With the right strategy, the development of TPU Dosay is expected to be an innovative solution in overcoming the shortage of green spaces in Jayapura Regency.

This study examines the comparative analysis of civil law systems between Indonesia and Malaysia, which adhere to the Civil Law and Common Law systems, respectively. Indonesia implements the Civil Law system, inherited from Dutch colonial rule and based on the Burgerlijk Wetboek (BW), whereas Malaysia adopts the Common Law system, derived from the English legal tradition. The fundamental difference between these systems lies in their sources of law, where Civil Law prioritizes codification through written statutes, while Common Law relies on jurisprudence and judicial precedents. Additionally, Malaysia employs a mixed legal system, incorporating elements of Customary Law and Islamic Law in specific legal matters. This study further explores the potential for harmonization of civil law between Indonesia and Malaysia through the Private International Law (PIL) framework, which facilitates cross-border dispute resolution based on the lex patriae and lex domicilii principles. By employing a Juridical-Normative methodology and adopting Comparative, Analytical, and Conceptual approaches, this research underscores the significance of understanding legal system differences to enhance legal cooperation between the two nations.

This study aims to evaluate the effectiveness of the National Cash Social Assistance (BST) policy on the purchasing power of communities in Surabaya. BST is a social protection program launched by the Indonesian government in response to the economic impact of the COVID-19 pandemic. The policy targets low-income and vulnerable groups through direct cash transfers, with the goal of maintaining basic consumption levels and preventing a sharp decline in household welfare. This research examines the extent to which the BST program has achieved its objectives, particularly in enhancing or sustaining the purchasing power of its beneficiaries in urban settings. The study employs an evaluative approach using a mixed-methods design, combining quantitative survey data with qualitative interviews involving aid recipients and local-level implementers. The findings indicate that the BST program had a positive short-term impact on household purchasing power, particularly in meeting essential needs such as food and utility expenses. However, several implementation challenges were also identified, including issues of inaccurate beneficiary targeting, delays in distribution, and the relatively small amount of assistance compared to actual household need. These results highlight that the effectiveness of social policy is not solely dependent on budget allocation but also on the precision of its implementation on the ground. Consequently, the study recommends improvements in beneficiary data updating, enhanced transparency in aid distribution, and the development of more adaptive program designs that reflect local socio-economic conditions. The findings are expected to serve as a valuable reference for policymakers in designing more efficient and sustainable social assistance programs in the future.

Many people utilize social media to interact, including students who are the most technologically literate. Apart from having a positive impact on its users, social media also has a negative impact. One of the negative impacts of social media is the increased risk of personal data security. The purpose of this study is to analyze the level of awareness of students in Yogyakarta regarding the protection of personal data on social media. The method used is mixed method, surveys were distributed to respondents, namely students from various schools in Yogyakarta. Researchers also conducted interviews with 15 participants to get a more in-depth picture. This research examines the level of understanding and awareness of students in Yogyakarta regarding how they understand data sharing behavior, privacy settings and their perceptions of threats or risks in cyberspace. The results showed that the majority of students have a high level of awareness regarding basic privacy measures, but they also have a poor understanding of the threats and risks associated with sharing personal data.The majority of students rarely update their privacy settings. They only use the default settings built into social media. The implication of the study is the need to integrate digital literacy programs that focus on data security and privacy into the school curriculum. The conclusion is that there is awareness among students regarding the importance of protecting personal data, but more efforts are needed to improve students' knowledge in digital privacy management. Further research is needed to assess the long-term impact of educational interventions on privacy-conscious behavior in the digital world.

Language plays a crucial role in human daily activities. In using language, people cannot avoid using various language varieties that reflect the context and social background of the speakers. Therefore, the importance of sociolinguistic studies has a major influence in recognizing language variations that emerge in communication, especially in the digital space. This study aims to examine the language variations used in comments on the Instagram account of Nur Rofiah, a public figure who is known to be active in voicing gender justice issues from an Islamic perspective. This study uses a sociolinguistic approach to identify forms of language variation and the social factors that influence them. Data were collected through documentation methods on comments on a number of Nur Rofiah's uploads that were considered representative. The results of the study show that there are various language variations, including variations based on dialect, level of formality, use of mixed language (code-mixing), and emotive varieties that reflect the identity and social background of the user. In addition, it was found that factors such as age, gender, educational background, and ideological orientation also influence language choices in digital interactions. These findings indicate that social media is not only a communication space, but also an arena for expressing people's social and ideological identities.

This study aims to provide a new understanding for people who are interested in the parousia of Christ as the resurrection of man. The location of this study was at the GKPI Jemaat Khusus Pandumaan, and used a mixed method, namely quantitative, distributing questionnaires to randomly selected respondents, and qualitative, interviewing people who were considered qualified by the researcher. It is interesting that the congregation of the GKPI Jemaat Khusus Pandumaan believes that the parousia of Christ will occur but they do not understand what its function is for them, both between the relationship between the parousia of Christ and the resurrection of man from the dead in the future. Referring to a conclusion, the Parousia of Christ is a resurrection for man because after man dies the flesh and spirit are separated and then the spirit stops until the parousia takes place, then the dead man is resurrected. So to every local church, especially the pastor who functions as the leader of the church, to study this teaching more deeply so that church members know the meaning and purpose of the parousia of Christ.

This study aims to analyse and implement the calculation of Cost of Goods Sold (COGS) using the full costing method at UMKM Rasa Dewa to increase profitability and help set more realistic and competitive selling prices. This study uses a mixed approach, namely qualitative and quantitative methods. The results of the study indicate that the calculation of COGS using the full costing method provides higher results than the simple method previously used by UMKM. The difference in production costs found was IDR 1,402,371 for starfruit juice products and IDR 2,881,150 for starfruit syrup products. This is due to the use of the full costing method which includes all cost elements, both direct and indirect costs such as depreciation of equipment, transportation, and other overhead costs that were not previously calculated. Meanwhile, the initial calculation of UMKM Rasa Dewa only included basic costs such as raw materials, direct labor, and packaging materials. By implementing the full costing method, UMKM can obtain a more accurate and comprehensive picture of production costs. This provides a more appropriate basis for consideration in setting product selling prices to increase profitability sustainably.

The effectiveness of the Windows Shopping strategy in enhancing the speech writing abilities of eighth-grade students at four government junior high schools in Cilacap Regency, Indonesia, is examined in this study. The study is based on the demand for novel instructional methods that assist students with the challenges of arranging thoughts, choosing the right vocabulary, and creating well-written sentences while writing speeches. The study used a mixed methods approach with an explanatory sequential design, consisting of pretests and posttests administered to 128 pupils, along with qualitative data from observations, interviews, and reflections. With average scores rising from 61. 63 (pretest) to 81. 97 (posttest), the results showed a notable improvement in students' performance. The statistical significance was confirmed by a paired sample t-test (t = 11. 52, p = 9. 83 × 10⁻¹³). Qualitative data also showed that students were more engaged, creative, and confident during group learning sessions. The Windows Shopping method, in accordance with social constructivist learning principles, encouraged students to actively explore, present, and reconstruct information through group interaction. This approach, according to the study, is effective in improving students' speech writing abilities and promoting essential 21st century skills such as creativity, collaboration, and communication. It should be used more widely in other text-based language instruction as well.

Regional tourism development is a crucial strategy for driving local economic growth and preserving cultural heritage. However, field conditions often reveal that policy implementation does not always proceed optimally. The Sekarsari Bathing Area in Mojokerto City is one of the tourism sites targeted by development policies, yet it has not demonstrated significant impact on community welfare or tourism attractiveness. This study aims to evaluate the implementation of regional tourism development policies at the Sekarsari site using William N. Dunn’s policy evaluation theory, which includes six criteria: effectiveness, efficiency, adequacy, equity, responsiveness, and appropriateness. This research adopts a qualitative approach with a case study design. Data were collected through in-depth interviews, field observations, and document analysis from various stakeholders such as the tourism office, site managers, local businesses, and community members. The research instruments were developed flexibly and iteratively according to field dynamics. Data analysis was conducted through data reduction, data display, and conclusion drawing in an interactive manner. The findings reveal that the tourism development policy at Sekarsari has not yet yielded optimal outcomes. The main weaknesses lie in the lack of community participation, uneven distribution of economic benefits, and limited innovation and promotion. Although there have been improvements in basic infrastructure and a modest increase in visitor numbers, the policy has not been fully responsive to local needs. In conclusion, the current policy does not fully meet Dunn’s six evaluation criteria and requires revisions in both strategic planning and technical implementation. This study recommends that future tourism policies be more community-based, inclusive, and adaptive to local contexts. For future research, a mixed-methods approach involving quantitative and geospatial analysis is suggested to strengthen comprehensive evaluative evidence.    

Robusta coffee (Coffea canephora) is one of Indonesia’s important agricultural commodities with strong economic potential. However, optimizing its productivity depends heavily on proper cultivation practices, particularly pruning, which significantly affects plant health and fruit yield. This study focused on the Women's Farmer Group (Kelompok Wanita Tani/KWT) in PTPN 1 Regional V Kebun Bangelan, East Java, which faced challenges due to limited skills and knowledge in coffee pruning. A community-based agricultural extension program was implemented to enhance their technical capabilities and ensure compliance with standard operating procedures (SOP) for effective pruning. The objectives were to identify key issues in pruning practices, deliver targeted training, and evaluate the outcomes. Using a mixed-methods approach—comprising participatory observation, structured interviews, focus group discussions (FGD), and a pre-test/post-test comparison—the study assessed knowledge gains and training impact. A Likert-scale survey further measured participant satisfaction. Findings revealed four main issues: low SOP adherence, lack of training, poor tool maintenance, and plant morphological constraints. Post-intervention, participant knowledge rose from 49% to 97%, a 48% improvement. Additionally, 71.88% of respondents rated the training positively. This indicates that structured, practical training significantly improved pruning skills, contributing to better agricultural practices and productivity in smallholder communities.

This study conducts an in-depth examination of 87 mixed-method studies that address war-related trauma in the Middle East over the past two decades (2000–2023), employing a systematic methodological meta-synthesis approach to formulate a more comprehensive understanding of the impact of armed conflict on affected populations. Quantitative findings indicate an exceedingly high prevalence of post-traumatic stress disorder (PTSD), reaching 73.4% among war refugees (n = 12,456), accompanied by significant comorbidity rates in the form of depression (68.2%) and anxiety disorders (59.7%), both of which clinically exacerbate recovery prognosis. Meanwhile, the thematic qualitative analysis successfully identified five principal dimensions of recurrent traumatic experiences, namely direct exposure to violence (82.3%), the loss of family members (76.9%), forced displacement (71.4%), existential uncertainty regarding the future (68.9%), and the disintegration of social cohesion within affected communities (65.2%). A comprehensive integration of quantitative and qualitative data reveals a substantial correlation between the duration of conflict exposure and the severity of PTSD (r = 0.78, p < 0.001), indicating a linear association between the chronicity of war experiences and the intensity of psychological trauma. Through meta-regression, this study also identifies several statistically significant protective variables that reinforce both individual and collective resilience, including the presence of family support (β = 0.45, p < 0.001), the intensity of religiosity (β = 0.38, p < 0.01), and the strength of community resilience (β = 0.42, p < 0.001), all of which function as moderating factors of traumatic impact. In contrast to the narrow focus of Storozhuk et al. (2023) and Boeije et al. (2013), who emphasized individual trauma, this study advances a broadened paradigm by exploring the collective dimensions of war trauma made possible through an integrative methodological design. While Zerach and Solomon (2016) previously proposed three core categories of traumatic experience, the present study expands the conceptual spectrum by identifying two additional themes and unveiling the complex network of interrelations among trauma elements. The principal novelty of this study lies in the formulation of an integrative model of war trauma that not only theoretically unifies individual and collective dynamics but also constructs a new methodological framework that may serve as a reference point for trauma research in conflict-affected regions marked by the volatile and multidimensional sociopolitical context of the Middle East.
