Article 20 of the Personal Data Protection Law (PDP Law) normatively regulates the protection of data subjects and constitutes a pivotal provision that underscores the principle of consent as the legal basis for the processing of personal data for commercial purposes. This normative framework safeguards individuals’ right to privacy, encompassing the validity of explicit consent, the right to withdraw such consent, and the accountability of data controllers. In parallel, Articles 65 to 70 of the PDP Law substantively establish various categories of criminal offenses within the context of personal data protection. These include the unlawful acquisition, disclosure, processing, falsification, and utilization of personal data. Collectively, these provisions reflect the State’s commitment to ensuring criminal legal protection against violations of personal data.This research adopts a doctrinal legal methodology with a descriptive-normative approach to address two primary issues: First, to examine and identify the scope of legal protection concerning the trade of personal data under the PDP Law; and Second, to assess and determine the degree of legal certainty afforded to the trade of personal data within the framework of the PDP Law.Notwithstanding the protective intent embodied in Article 20—particularly concerning the commercial use of personal data—this provision gives rise to legal uncertainty due to the absence of comprehensive regulatory clarity on several critical aspects. Similarly, Articles 65 to 70 continue to exhibit significant legal ambiguities, particularly with respect to the constituent elements of offenses, the definition of harm, corporate liability, regulatory overlap with other legislative instruments, and the lack of clear enforcement mechanisms and implementing institutions.

This study aims to comprehensively examine the role of social media influencers in shaping public opinion among university students through a literature review approach.

Regarding regulations, the village government has established basic policies through decrees forming community groups and regulating the digital village program, although these have not been comprehensively integrated. In terms of human resource quality, village officials and young cadres are relatively adaptive to technology, but a capacity gap remains among older age groups. Overall, the implementation of smart government through the Sumbergedang Baru Program is still at the stage of building a digital village foundation, requiring further improvements in digital literacy, human resources, infrastructure expansion, and technology-based transparency.

Proton Exchange Membrane Fuel Cells (PEMFCs) are increasingly developed due to their high efficiency, power density, durability, and environmental friendliness. However, the high cost of platinum catalysts limits their widespread application. Reducing platinum usage through the development of low-cost catalyst support materials is a promising approach. Activated carbon derived from biomass offers a sustainable and economical alternative, particularly when utilizing agricultural waste such as coffee husks, which are often discarded. This study aims to evaluate the characteristics of activated carbon produced from coffee husk waste through pyrolysis as a catalyst support for PEMFCs. Pyrolysis was conducted at 400 °C, followed by chemical activation using 1 M H₃PO₄ and 1 M KOH with a residence time of 90 minutes. The resulting activated carbon was analyzed through proximate analysis to determine moisture content, ash content, volatile matter, and fixed carbon content. The results showed that activation with 1 M H₃PO₄ produced the lowest moisture content (3.4%), the lowest ash content (3.8%), and the highest fixed carbon content (60.5%), while 1 M KOH yielded the lowest volatile matter content (27.7%). Based on these results, activated carbon produced using H₃PO₄ meets the requirements of SNI No. 01/6235/2000 and demonstrates strong potential as a catalyst support material for PEMFC applications.

Chronic liver disease is a significant health problem and places a significant burden on healthcare services. Deaths from complications of chronic liver disease (cirrhosis and cancer) account for approximately 3.5% of all deaths worldwide each year. Hepatocellular carcinoma (HCC) is a primary liver tumor, accounting for 90% of all liver tumors. Due to limitations in liver transplantation, liver resection is considered the treatment of choice for HCC patients with a single tumor and sufficient liver function reserve. Liver resection and transplantation are the only curative treatment options available for HCC patients. Surgical procedures require anesthesia. General anesthesia is the preferred method for liver tumor resection. There are five main classes of anesthetic agents: intravenous (IV) anesthetics, inhalational anesthetics, IV sedatives, synthetic opioids, and neuromuscular blocking agents. Estimated health risks depend on the extent or severity of liver disease, the nature and timing of surgery, the type of anesthesia, and other comorbidities.
