nces, from satisfaction with the ease of use of the service to complaints regarding bills, interest rates, late payment fees, credit limits, and app performance. This study aims to classify the sentiment of user reviews regarding PayLater services on the Kredivo and Akulaku apps using the Multinomial Naïve Bayes algorithm. Data was collected via web scraping from the Google Play Store and automatically labelled based on user ratings, with ratings of 1-2 classified as negative sentiment and ratings of 4-5 as positive sentiment, whilst a rating of 3 was excluded as it was considered ambiguous. Following a preprocessing stage comprising cleaning, case folding, tokenisation, stopword removal, and stemming, as well as feature extraction using TF-IDF, 3,652 reviews were obtained with a training-to-test data split ratio of 80:20. The results indicate that positive sentiment dominates the dataset at 56.49%, whilst negative sentiment accounts for 43.51%. Analysis by application revealed that Kredivo was dominated by positive sentiment (68.20%), whilst Akulaku was dominated by negative sentiment (51.70%). The Naïve Bayes multinomial model achieved an accuracy of 84.13%, with average precision, recall, and F1-score values of 0.84, demonstrating good and balanced classification performance across both sentiment classes.
Abstract:This research is motivated by the issue of the effectiveness of witness and victim protection within the Indonesian criminal justice system, which is considered not yet to fully reflect the values of restorative justice…
nor to be harmoniously integrated into the framework of the national legal system. Although regulatory frameworks have been established through Law Number 13 of 2006 as amended by Law Number 31 of 2014 concerning the Protection of Witnesses and Victims, as well as various regulations related to whistleblower and justice collaborator protection, their implementation continues to face normative and structural weaknesses. The lack of synchronization between the Criminal Procedure Code (KUHAP), the Draft Criminal Procedure Code (RUU KUHAP), and other sectoral regulations has resulted in the suboptimal role of the Witness and Victim Protection Agency (LPSK) in guaranteeing the rights of witnesses, victims, perpetrator-witnesses, and reporters, particularly in criminal cases with broad and organized impacts. From the perspective of maqāṣid al-syarī‘ah and the Pancasila Justice Theory, legal protection for witnesses and victims should not be merely procedural-formal in nature, but must be directed toward the restoration of dignity, the assurance of security, and the comprehensive protection of human rights. This study aims to analyze the regulatory weaknesses in witness and victim protection from the perspective of the criminal justice system and to reconstruct such regulations based on restorative justice values. Employing a normative legal research paradigm combined with conceptual, statutory, and theoretical approaches, this research positions the Pancasila Justice Theory as the grand theory, the Legal System Theory as the middle theory, and the Legal Protection Theory as the applied theory. The findings indicate that regulatory reconstruction is necessary through strengthening the institutional position of LPSK, harmonizing it with the Draft Criminal Procedure Code (RUU KUHAP), and reinforcing the protection of whistleblowers and justice collaborators in a more comprehensive and non-discriminatory manner. This reconstruction is directed toward establishing a witness and victim protection system oriented toward restoration (restorative justice), balanced interests among the parties, and the realization of social justice as mandated by the values of Pancasila and human rights principles.
Abstract:This research comprehensively analyzes the glass industry development policy on Rempang Island, Batam City, Riau Islands Province, using an environmental risk mitigation approach. Employing a descriptive qualitative method…
od with a case study design and library research, this study examines five main dimensions: the chronology of the Rempang Island case, policy conflicts and controversies, the government regulatory framework, disaster risk analysis from nine environmental perspectives, and overall policy evaluation. The findings reveal that the Rempang Eco City project, designated as a National Strategic Project (PSN) through Permenko for Economic Affairs Number 7 of 2023, triggered prolonged agrarian conflict due to the absence of meaningful participation from indigenous Malay communities who have inhabited 16 ancient villages on the island since 1834. The project implementation was marked by forced evictions, repeated acts of violence, and non-transparent environmental impact assessment (AMDAL) processes. Disaster risk analysis from nine environmental perspectives covering air quality, water quality, coastal and marine ecosystems, sand mining and geological degradation, biodiversity, community health, social-cultural impacts, climate change vulnerability, and environmental governance consistently produces high-risk assessments, affirming that Rempang Island as a small island ecosystem lacks adequate carrying capacity for large-scale glass industrial development without permanent and irreversible ecological damage. Although Presidential Regulation Number 12 of 2025 de facto removed Rempang Eco City from the list of 77 National Strategic Projects under President Prabowo Subianto’s administration, the absence of an explicit revocation of Permenko Number 7 of 2023 creates ongoing legal ambiguity for affected communities. This research concludes that Indonesia urgently requires fundamental reform in its investment-based development policy paradigm, encompassing strengthened indigenous community participation mechanisms, elevation of AMDAL as a non-circumventable legal requirement prior to investment designation, and application of the ecological precautionary principle in small island development.
Abstract:This study aims to analyze the relationship and influence of coal quality parameters which include Total Moisture (TM), Ash Content (ASH), and Total Sulfur (TS) on Gross Calorific Value (GCV). The data used in this study…
is data from laboratory tests on 23 samples of Run Of Mine (ROM) coal at seam 16 at PT Unggul Nusantara, North Barito Regency, Central Kalimantan. Data analysis was performed statistically using the help of SPSS software through Pearson correlation test and multiple linear regression analysis. The results of the correlation test showed that simultaneously, the TM, ASH, and TS parameters had a very strong relationship with the GCV value with a correlation coefficient (R) of 0.893 and contributed an influence of 76.5%. Partially, Ash Content (ASH) had a very strong negative relationship (r = -0.881) and had a significant effect on calorie values (p = 0.000). Each 1% increase in ash content would decrease the GCV value by 68.249 Kcal/Kg. Meanwhile, Total Moisture had a significant positive relationship by simple correlation (r = 0.506, p = 0.014), but showed no partial significant effect in multiple regression models (p = 0.364). Total Sulfur was found to have a very weak negative relationship (r = -0.182) and had no significant effect on GCV values (p = 0.406). This study concludes that Ash Content is the most dominant parameter that affects the reduction of the caloric value of coal seam 16 at PT Unggul Nusantara.
Abstract:This study aims to analyze the concept and application of hospital criminal liability in cases of medical malpractice in the Indonesian criminal law system, as well as examine the relationship between the individual responsibility…
onsibility of medical personnel and the responsibility of hospital institutions. This study uses a qualitative approach with case study methods and a juridical-normative approach enriched with empirical data. Data was collected through in-depth interviews with legal practitioners, medical personnel, and hospital managers, accompanied by a documentary study of laws and regulations, court rulings, and related literature. The results of the study show that criminal liability in cases of medical malpractice is generally still focused on individual medical personnel as direct perpetrators, while the accountability of hospital institutions has not been optimally applied in criminal law enforcement practices. In addition, it was found that there is a complex relationship between the professional responsibilities of medical personnel and the institutional obligations of hospitals in ensuring health service standards, including aspects of supervision, risk management, and medical service systems. This study concludes that it is necessary to strengthen the concept of corporate criminal liability for hospitals in cases of medical malpractice in order to create legal certainty and more balanced protection for patients, medical personnel, and health service institutions. The findings of this study contribute to the development of health law studies and become a basis for consideration for policymakers in formulating more effective regulations and law enforcement mechanisms.
Abstract:Blood group examination is a blood grouping system based on the type of antigen. Examination of blood groups with antisera reagents, namely examination of blood groups with antisera reagents obtained from in vitro supernatant…
atant cultures derived from mouse cell immunoglobulin hybridization. Examination of blood type with serum is an examination that uses blood type A as anti-B, blood type B as anti-A, and blood type O as anti-AB. The purpose of this study was to determine the profile of the ABO system blood group examination using antisera reagents and serum slide method. The research method used was descriptive with samples of the ABO system blood group using antisera and serum reagents for 30 respondents using probability sampling technique. The materials used are human blood groups A, B, AB and O and anti-A, anti-B, anti-AB reagents. Data analysis was descriptive in the form of a profile table of the results of the ABO system blood group examination using antisera and serum reagents. The results of the study revealed that the results of blood group A were 7 (23%), blood group B were 7 (23%), blood group AB were 8 (27%), and blood group O were 8 (27%). The results obtained showed that the antisera and serum reagents had differences in the blood group examination results, namely the grade of agglutination produced by the serum was different from that of the antisera. It can be concluded that the results of blood grouping with antisera and serum reagents can be used for blood group examination. However, compared to antisera reagents, the results are better using antisera reagents compared to serum.
Abstract:This study aims to analyze the communication strategy employed by the NEI-DT Foundation in building community trust through a community-based healthcare service program in Tritunggal Hamlet, Banyuasin Regency, South Sumatra,…
tra, Indonesia. The study is motivated by the importance of organizational communication strategies in enhancing public participation and program legitimacy within rural communities characterized by limited access to information, geographical constraints, and community-oriented social structures. Adopting a constructivist paradigm, this research employs a qualitative approach using an intrinsic case study design. Data were collected through in-depth interviews, non-participant observation, and document analysis involving seven informants, including foundation representatives, community leaders, and program beneficiaries. Data were analyzed using the interactive model of Miles, Huberman, and Saldaña, encompassing data condensation, data display, and conclusion drawing. The findings reveal that the foundation’s communication strategy involves identifying community characteristics, developing simple and contextually relevant messages, utilizing a combination of digital and traditional communication channels, and engaging local leaders as communication intermediaries. Program information is disseminated through village heads, neighborhood leaders, women’s community groups (PKK), social media platforms such as WhatsApp and Facebook, and mosque loudspeaker announcements. The study further demonstrates that the communication pattern reflects the Two-Step Flow of Communication model, in which community leaders function as opinion leaders who mediate organizational messages before they reach the wider community. Community trust is cultivated through the social legitimacy of local leaders, interpersonal communication, direct experiences with program benefits, and the consistency of services provided by the foundation. The study concludes that the effectiveness of community-based organizational communication strategies in rural settings is determined not only by message content and media utilization but also by the organization’s ability to establish interpersonal relationships, adapt communication practices to local cultural contexts, and actively involve community leaders within the communication network. This research contributes to the advancement of community-based organizational communication studies by providing empirical insights into trust-building processes in rural community development programs

Abstract:Karstification is the dominant geological process controlling groundwater circulation and permeability in carbonate aquifers. Through the dissolution of carbonate rocks, karst processes create highly heterogeneous systems…
s characterized by fractures, conduits, and interconnected channel networks that significantly influence groundwater flow dynamics. This literature review aims to synthesize current knowledge regarding the effects of karst on water circulation and permeability in carbonate aquifers based on hydrogeological, hydrochemical, geophysical, and numerical modeling studies from various regions worldwide. The review shows that karstification substantially enhances hydraulic conductivity and produces complex flow regimes ranging from diffuse fracture flow to turbulent conduit flow. The epikarst zone plays an important role in regulating infiltration and recharge distribution, while tectonic structures such as faults and fractures strongly control groundwater pathways and aquifer compartmentalization. Karst aquifers also exhibit strong spatial variability in permeability, making groundwater flow and contaminant transport difficult to predict using conventional hydrogeological approaches. In addition, the integration of equivalent porous medium (EPM), discrete fracture network (DFN), and conduit network (CN) models is essential for accurately representing karst aquifer behavior. Understanding the influence of karstification on groundwater circulation is therefore crucial for sustainable groundwater management and aquifer vulnerability assessment, particularly in regions facing increasing water demand and climate change pressures.
Abstract:This study aims to analyze the determinants of dividend policy and their implications for stock returns among companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2024 period. Specifically, the study examines…
examines the effects of Return on Assets (ROA), Current Ratio (CR), Debt-to-Equity Ratio (DER), Sales Growth (SG), and Firm Size (SIZE) on Dividend Payout Ratio (DPR), as well as the impact of DPR on stock returns. The research employs a quantitative approach using secondary data obtained from the annual financial reports of dividend-paying companies listed on the IDX. The sample consists of 822 firm-year observations selected through purposive sampling. Data analysis was conducted using path analysis with multiple regression models, supported by classical assumption tests including normality, heteroscedasticity, multicollinearity, and autocorrelation tests. The results indicate that during the overall period of 2019–2024, ROA, DER, and SG significantly and negatively affect DPR, while CR and SIZE do not have significant effects. Furthermore, CR negatively affects stock returns, whereas SG and DPR have positive and significant effects on stock returns. The findings also reveal that the relationships among financial performance, dividend policy, and stock returns vary across pre-crisis, crisis, and post-crisis periods. Overall, dividend policy plays an important mediating role in influencing stock returns, particularly during and after periods of financial uncertainty. These findings provide valuable insights for investors, corporate managers, and policymakers in formulating dividend and investment decisions under different economic conditions.
