Abstract

Distribusi gas LPG 3 Kg memerlukan perencanaan rute yang efisien untuk menekan biaya operasional, menghemat waktu, dan meningkatkan keamanan pengiriman. Penelitian ini bertujuan untuk mengoptimalkan pemilihan rute terpendek distribusi gas LPG 3 Kg dengan menerapkan Algoritma Sweep berbasis Python pada kasus Capacitated Vehicle Routing Problem (CVRP). Data yang digunakan meliputi lokasi pelanggan, jarak antar titik, dan kapasitas angkut truk. Algoritma Sweep digunakan untuk mengelompokkan pelanggan berdasarkan sudut polar relatif terhadap depot, dilanjutkan dengan penentuan urutan kunjungan yang meminimalkan jarak tempuh sambil memenuhi batas kapasitas kendaraan. Hasil optimasi menunjukkan bahwa metode ini mampu menghasilkan tiga rute distribusi dengan total jarak tempuh 98,7 km, mengalami pengurangan sebesar 26,18 km atau sekitar 21% dibandingkan kondisi awal yang mencapai 124,88 km. Selain itu, jumlah armada dapat ditekan menjadi tiga truk tanpa melanggar batas kapasitas angkut. Implementasi berbasis Python memungkinkan proses penghitungan dan pemodelan rute dilakukan secara cepat, akurat, dan dapat diulang untuk berbagai skenario distribusi.

Abstract

In Indonesia, the use of construction waste is usually not utilized properly most are simply dumped in open fields, and some are used as backfill material. The availability of such materials is vast. The purpose of this research is to determine the compressive strength value of paving blocks that utilize concrete waste with variations in the use of concrete waste, namely: 0%, 10%, 20, 30%, and the value of water absorption in paving blocks that utilize concrete waste with variations in the use of concrete waste, namely: 0%, 10%, 20, 30%. The test results showed that at 28 days of soaking, the compressive strength of normal paving blocks was 16.15 MPa, at 10% substitution of concrete waste for stone ash was 29.17 MPa, at 20% substitution of concrete waste to stone ash amounted to 39.32 MPa, and at 30% substitution of concrete waste to stone ash amounted to 22.66 MPa. From the results of the absorption test, it was found that the absorption value of normal paving blocks was 3.88%, at 10% substitution of concrete waste was 2.30%, at 20% substitution of concrete waste for stone ash was 1.89%, and at 30% substitution of concrete waste for stone ash was 2.80%.

Abstract

Artificial Intelligence (AI) is reshaping the legal profession by enhancing research speed, document review, and case analysis. Yet, its integration also raises pressing concerns over accountability, data privacy, and ethical standards. This study addresses the research problem: How should Indonesia regulate AI in law to balance innovation with justice and human rights? Three guiding questions inform the analysis: (1) What is the extent of AI adoption by Indonesian legal practitioners? (2) What legal and ethical risks arise? (3) What regulatory responses are most suitable for Indonesia’s plural legal context? Adopting a socio-legal methodology, data were collected through literature review, in-depth interviews, and an online survey of 102 practitioners. Findings show that 38% of respondents currently use AI tools, mainly for legal drafting and research, but skepticism persists. Advocates in Semarang reported errors in AI-generated contracts, illustrating unresolved accountability gaps under existing laws. Judges highlighted risks of bias and opacity if AI expands into case management without safeguards. The novelty of this research lies in its empirical evidence: it is the first Indonesian study to combine practitioner perspectives with regulatory analysis, moving beyond conceptual debates. By linking adoption patterns to deficiencies in the ITE Law, PDP Law, and PERMA No. 1/2019, the study reveals concrete vulnerabilities in legal practice. The study concludes that interim sectoral measures such as PERADI guidelines and judicial ethics updates are urgently needed while developing a comprehensive AI law. Responsible governance is essential to ensure AI strengthens, rather than undermines, fairness, transparency, and the rule of law.

Abstract

This study aims to analyze the application of the first to file principle  in providing legal protection to trademark rights holders in Indonesia, especially in trademark disputes involving well known brands. The background of this research is based on the fact that there is still a frequent conflict between legal certainty for the first registrant and substantive justice for those who have a reputation and use of the trademark first. This research is urgent due to ongoing issues concerning practice of trademark registration carried out in bad faith, which has the potential to cause unfair business competition and harm the owner of the brand in good faith. This research uses a normative juridical method with a legislative approach and a case approach, which focuses on Decision Number 12/Pdt.Sus-HKI/Memerk/2024/PN Niaga Central Jakarta related to the MONSTER and 4MONSTER trademark disputes. The originality of this research lies in its analysis of the application of the first to file principle  in the latest commercial court decisions with an emphasis on the consideration of bad faith and the protection of well-known brands. The findings of the study show that although the Indonesian trademark legal system adheres to  the principle of first to file which is constitutive, legal protection is not provided absolutely if the trademark registration is conducted in bad faith. This article concludes that the ruling strengthens substantive justice and provides important guidelines in balancing legal certainty and fairness in trademark law enforcement in Indonesia.

Abstract

The development of non-traditional brands has led to the expansion of trademark legal protection, including against sound brands. In Indonesia, voice trademarks have been recognized normatively in Law Number 20 of 2016 concerning Trademarks and Geographical Indications and are registered through an online trademark registration system managed by the Directorate General of Intellectual Property. However, this recognition raises various legal and institutional issues, especially related to legal certainty, technical standards for registration, and the effectiveness of the online registration mechanism. This study aims to analyze the normative regulation of voice trademark registration in the Indonesian legal system and examine the legal implications of online voice trademark registration. This study uses a normative legal research method with a legislative approach and a comparative legal approach, by comparing the regulation and practice of voting trademark registration in Indonesia, Australia, and the European Union. In addition, a conceptual approach is used to examine the concept of non-traditional brands, differentiating power, and legal certainty. The results show that although sound trademarks have been normatively recognized, the trademark registration system in Indonesia has not been supported by adequate technical arrangements and operational standards. The absence of examination guidelines and limited transparency in the online registration system create legal uncertainty and expand the administrative discretion of the examiner. This condition has an impact on weak legal protection for applicants and interested parties. This study concludes that strengthening implementing and institutional regulations is needed to realize effective, transparent, and fair registration of voice trademarks.
