The rapid growth of digital marketplaces has fundamentally transformed consumer decision-making processes by intensifying price transparency, product comparability, and information exposure. In highly competitive marketplace environments, consumers are frequently confronted with numerous product alternatives and dynamic pricing structures, which shape how they evaluate options and ultimately decide to purchase. This study examines the effects of product variety and price perception on consumers’ purchase decisions in the context of ROSCA tumbler products sold on the Shopee marketplace. Using a quantitative explanatory approach, this research employs a survey-based design to analyze the relationships among variables and to estimate their relative effects through multiple linear regression analysis. Data were collected from 100 respondents who had previously purchased ROSCA tumblers on Shopee, selected using purposive sampling based on predefined criteria. The research instrument consisted of 15 Likert-scale items measuring product variety, price perception, and purchase decision. Data analysis included descriptive statistics, instrument validity and reliability testing, regression assumption diagnostics, and hypothesis testing using both partial (t-test) and simultaneous (F-test) procedures. The findings reveal that product variety has a positive and significant effect on purchase decisions, indicating that consumers are more likely to finalize purchases when they perceive product options as sufficiently diverse, relevant, and comparable. Price perception also exerts a positive and significant influence and demonstrates a stronger relative effect compared to product variety. This result underscores the central role of perceived price fairness, competitiveness, and value-for-money in shaping purchase decisions within transparent and highly competitive marketplace settings. Simultaneously, product variety and price perception explain a substantial proportion of variance in purchase decisions, highlighting their combined importance as key marketing stimuli. These findings contribute to the literature on digital consumer behavior by providing empirical evidence from a specific marketplace–product context and offer practical implications for sellers and brand managers in optimizing assortment design and pricing strategies to enhance conversion rates in online marketplaces

Postoperative pain is a common physiological response following surgical procedures, and its suboptimal management can have physiological and psychological effects, including sleep disturbances, decreased functional capacity, increased anxiety, and deterioration in quality of life. This scoping review aims to describe the empirical evidence regarding the effectiveness of music therapy in reducing the intensity of postoperative pain in surgical patients. A systematic search was conducted through four major databases (ScienceDirect, PubMed, Neliti, and Google Scholar) using Boolean operators and keywords such as ‘postoperative pain,’ ‘music therapy,’ and ‘pain scale.’ Inclusion criteria included articles published in the last decade, in English or Indonesian, and available in full text format. In accordance with PRISMA-ScR guidelines, this review analysed 10 articles. The synthesis of results showed that music therapy consistently reduced pain intensity, anxiety, and analgesic requirements through mechanisms such as increased endorphin secretion, decreased stress hormone levels, and activation of the gate control theory. Typically administered for 15–30 minutes, music therapy is a safe, cost-effective, and patient-acceptable non-pharmacological modality. This intervention is recommended as an adjunct component in perioperative pain management in nursing practice, although further standardised research is needed to improve consistency.

Aortic dissection is a cardiovascular emergency characterized by a tear in the aortic intima layer and the formation of a false lumen, posing risks of fatal complications such as rupture and organ malperfusion. Stanford type B dissections may be managed conservatively; however, complicated cases require intervention. Thoracic Endovascular Aortic Repair (TEVAR) has emerged as the preferred modality, offering lower perioperative morbidity and mortality compared to open surgery. To report the first TEVAR procedure performed in Manado on a patient with Stanford type B aortic dissection, highlighting the technical approach, operative challenges, and clinical outcomes. A 62-year-old male with a history of hypertension and chronic chest pain was referred following a CT angiography that revealed a Stanford type B aortic dissection with an entry site in the proximal descending aorta. TEVAR was performed with stent-graft placement in zone 2 and a chimney graft to preserve perfusion of the left subclavian artery (LSA). Intraoperative aortography confirmed false lumen exclusion without endoleak. The patient showed significant clinical improvement and recovered without postoperative complications. The procedure was technically and clinically successful, with no major complications. Postoperative evaluation confirmed stable stent position and maintained LSA perfusion. This case demonstrates that TEVAR can be safely implemented in non-tertiary regional hospitals with thorough preparation. The first TEVAR procedure in Manado illustrates that this technique can be an effective solution for complicated type B aortic dissections. This experience marks a milestone in the development of endovascular services in resource-limited settings and may serve as a reference for similar institutions in Indonesia.

Human trafficking constitutes a transnational crime that inflicts physical, psychological, and economic suffering upon its victims. This research aims to analyze the fulfillment of restitution rights for victims of human trafficking and examine preventive efforts from the immigration perspective. According to Law Number 21 of 2007 concerning the Eradication of Human Trafficking, every victim has the right to restitution as compensation for losses suffered. However, implementation in practice still encounters numerous obstacles, including weak law enforcement, limited understanding among law enforcement officers, and insufficient technical regulations. This normative legal research employs statutory and conceptual approaches to examine primary legal materials, including Law Number 21 of 2007, Law Number 6 of 2011 on Immigration, and various implementing regulations. The findings indicate that legal protection for victims of human trafficking has not been optimal, with challenges including difficulties in proving immaterial losses, dual procedural systems between the Human Trafficking Law and Criminal Procedure Code, and weak coordination among law enforcement agencies. The Witness and Victim Protection Agency (LPSK) often cannot guarantee restitution payments as determined by judges. From the immigration perspective, the Directorate General of Immigration plays a strategic role in preventing human trafficking through travel document control, implementation of the Integrated Border Control Management (IBCM) system, education for prospective migrant workers, and cross-sectoral collaboration. However, challenges persist, including complex and evolving modus operandi, limited resources in remote border areas, and inter-agency coordination obstacles. The study concludes that synergy between institutions and improvements in education and regulation are required to ensure victims' restitution rights are fulfilled effectively.

This research examines the effectiveness of narcotics crime investigation by the Narcotics Investigation Unit (Satuan Reserse Narkoba) from the perspective of Indonesia's Criminal Procedure Code (KUHAP) and related legislation. The study also analyzes the juridical-normative obstacles encountered during investigation processes, along with potential solutions under Indonesian positive law. As an extraordinary crime, narcotics offenses require precise and legally sound investigation methods. However, investigative practices often face challenges due to inconsistencies between legal norms and field implementation, limited resources, and the absence of clear regulations on special investigative techniques such as wiretapping and controlled delivery. This normative legal research employs statutory and conceptual approaches, analyzing primary legal materials including Law Number 8 of 1981 (KUHAP), Law Number 35 of 2009 on Narcotics, and various implementing regulations. The findings indicate that narcotics investigations are not yet optimal due to weak technical regulations, disharmonized laws between KUHAP and the Narcotics Law, overlapping authority between the Police and the National Narcotics Agency (BNN), and a lack of protection for whistleblowers and witnesses. The legal gap in regulating special investigation methods creates uncertainty in evidence admissibility. Proposed solutions include regulatory reform through KUHAP revision, improving investigator competence through specialized training, utilizing modern technology, strengthening inter-agency coordination, and enhancing internal and external oversight mechanisms. Legal reform and institutional synergy are essential to enhancing the overall effectiveness of narcotics investigations in Indonesia.

The right to health is a fundamental human right that remains inherent to prisoners. This study aims to examine the legal protection of prisoners' right to health care as regulated in Law Number 22 of 2022 on Corrections, as well as its implementation in correctional institutions. The research uses a normative juridical method with statutory and conceptual approaches. The findings show that Law Number 22 of 2022 formally guarantees prisoners' access to health services, including mental health care and special protection for vulnerable groups such as women, the elderly, and persons with disabilities. Key provisions in Articles 10, 11, 12, and 14 establish the state's obligation to provide adequate health services equivalent to community standards. However, in practice, the realization of this right faces several obstacles including: (1) overcapacity of correctional facilities exceeding 180% of ideal capacity, (2) limited medical personnel with many institutions lacking permanent doctors, (3) inadequate health facilities and medicine supplies, (4) complicated referral procedures causing delays in emergency treatment, and (5) insufficient budget allocation. Strengthening technical regulations, improving infrastructure, enhancing cross-sectoral collaboration, and implementing effective oversight mechanisms are essential to ensure effective protection of prisoners' health rights as mandated by the constitution and international human rights standards.
