The problem of undiscipline and disobedience in driving traffic is a problem that is still faced by law enforcement officials in Indonesia. The birth of Electronic Traffic Law Enforcement (ETLE) is a complementary effort in overcoming the problem of traffic order violations. So that its position does not eliminate conventional methods in direct traffic control. This study aims to analyze the effectiveness of ETLE in the law enforcement system in Tangerang Regency. The method used is empirical legal research using primary data and secondary data. The results show that although the ETLE system can improve efficiency and accuracy in traffic law enforcement, its effectiveness is still constrained by several factors. The limited number of monitoring points, lack of socialization to the public, and low legal awareness of motorists are the main obstacles. Although the number of traffic violations netted through ETLE is quite significant, there is still a need for infrastructure improvement, better socialization, and an approach to form a stronger legal culture among the community so that traffic law enforcement can run optimally and sustainably.

This study aims to analyse the short story Perempuan Buta Tanpa Ibu Jari by Intan Paramaditha using GÃ©rard Genette's narratological approach, focusing on five main aspects: order, duration, frequency, mood, and narrative voice. Using a qualitative descriptive method with a combination of re-reading. The analysis shows that this short story uses analepsis (flashback) to build a non-linear narrative structure, creating a dramatic and immersive effect. Duration manipulation lengthens or summarises certain scenes to highlight emotional aspects and tensions in the story, while repetition of events reinforces narrative meaning and symbolism. Shifts in mood create an emotional contrast between introspective reflection and narrative tension, while the use of an autodiegetic narrator allows the reader to experience the story through the subjective perspective of the main character. Thus, the narrative techniques applied in this short story not only build a dynamic plot, but also enrich the thematic and emotional depth of the story

This study aims to analyze the policy of eliminating bad debt bills for MSMEs in Indonesia based on Government Regulation Number 47 of 2024. This policy was initiated as a form of the government's commitment to support the sustainability of MSME businesses that are experiencing financial constraints due to bad loans. The approach used is normative juridical with descriptive-analytical specifications, where research is carried out through the study of documents and literature on primary, secondary, and tertiary legal materials. The results of the study show that this policy has the potential to ease the financial burden of MSMEs by providing ease of settlement of bad credit obligations. However, the effectiveness of the policy is highly dependent on transparent implementation, clear mechanisms, and strict supervision by the government and relevant financial institutions. This policy also faces challenges, especially in reaching MSMEs that are classified as unbanked or unbankable. This study concludes that regulatory updates and more inclusive policy innovations are needed to ensure that the benefits of this policy can be felt by all MSME actors. The integration of financial technology (Fintech) and the improvement of financial literacy need to be optimized to support a more effective and equitable elimination of bad debts.
