Microplastic pollution in tropical mangrove ecosystems represents an increasing environmental concern, particularly in coastal regions such as Pekalongan, Indonesia, where industrial and residential activities contribute substantially to plastic waste. This study aimed to isolate and preliminarily screen halophilic bacteria from mangrove sediments and seawater collected from a plastic-impacted coastal area. Using mineral salt medium (MSM) supplemented with polyethylene glycol (PEG), six bacterial strains were obtained and evaluated for their potential to interact with polyethylene (PE) and polypropylene (PP) on the basis of gravimetric weight loss measurements. Among the isolates, Halomonas Cupida A1, Marinobacter nauticus A6.3, and Marinobacter nauticus SD5.2 exhibited …


Effects Of The Psb-To-Ow Ratio And Light Intensity On Biogas Composition During Phototrophic-Assisted Anaerobic Fermentation Of Organic Waste, Kridsana Jirasansawat, Sirilak Prasertkulsak, Nitiwist Teangthai Jan 2026

Effects Of The Psb-To-Ow Ratio And Light Intensity On Biogas Composition During Phototrophic-Assisted Anaerobic Fermentation Of Organic Waste, Kridsana Jirasansawat, Sirilak Prasertkulsak, Nitiwist Teangthai

Applied Environmental Research

The integration of phototrophic processes into anaerobic fermentation offers a promising strategy for improving biogas quality; however, the combined effects of the photosynthetic bacteria-to-organic waste (PSB-to-OW) ratio and light intensity remain unclear. In this study, the photosynthetic bacteria (PSB)-assisted anaerobic fermentation of municipal organic waste under varying PSB-to-OW ratios and light intensities was evaluated. An optimal PSB-to-OW ratio of 1:2 resulted in significantly higher CH4 concentrations and lower CO2 and H2S concentrations than the other tested ratios did (p < 0.05). At this ratio, moderate illumination (2000 lx) resulted in the highest CH4 concentration (68.2 ± 0.3%), compared with 1000 lx (61.5 ± 0.4%) and 4000 lx (63.1 ± 0.5%). Under illumination, the CO2 and H2S concentrations were lower than those under dark conditions, indicating a more favorable biogas composition. Kinetic analysis indicated that CO2 and H2S exhibited apparent first-order behavior under illumination, with the highest rates occurring at 2000 lx (kH2S = 0.093 day-1; kCO2 = 0.059 day-1), suggesting light-dependent transformation processes. Metagenomic analysis revealed a microbial community dominated by sulfide-oxidizing (Chlorobium sp.), photoheterotrophic (Rhodopseudomonas sp.), and syntrophic bacteria, supporting coupled carbon conversion and sulfur transformation. Overall, optimization of the …

As an effort to concretize ethics, there is a process of formalizing ethics into a set of rules through a code of ethics. The code of ethics needs institutional enforcement instruments so that it can be effectively applied through ethical trials. Ethical courts, as institutions that adjudicate violations of the code of ethics, have the authority to issue decisions as a follow-up to cases of violations of the code of ethics that they handle. In carrying out its duties, ethical courts use ethical and moral analysis to assess the appropriateness of an action. This analytical approach differs from legal decisions …


Reforma Alutsista Dan Sumber Daya Alam: Menjawab Tantangan Hukum Internasional Dan Perdamaian Dunia, Wildan Azkal Fikri, Rohadhatul Aisy Jan 2026

Jurnal Hukum & Pembangunan

This study departs from the paradox of the failure to achieve world peace despite the existence of an established international legal regime. It addresses three main objectives: (1) identifying the key factors that undermine world peace; (2) analyzing the failure factors of international law to realize global peace; and (3) formulating a responsive international legal architecture to future peace agendas. The study employs a critical descriptive method with a socio-legal (non-doctrinal) approach, drawing on the analytical frameworks of neorealism, great powers oligarchy, and Third World Approaches to International Law (TWAIL). The qualitative analysis is conducted by examining power relations, the …

To prevent land speculation by land mafias in the Nusantara Capital City (IKN), the government introduced a land-freezing policy aimed at restricting the transfer of land rights within the IKN area. However, in practice, this policy has been alleged to hinder land registration processes and undermine civil rights of communities within the IKN delineation zone. This study seeks to examine the regulatory framework, implementation, and impacts of the land-freezing policy on land registration and the civil rights of affected communities. Employing an empirical normative legal research method with a statute approach, this research finds that the land-freezing policy has not …

Strengthening idea of constitutional democracy as a transitional phase towards a modern rule of law requires one of main characteristics of an independent judiciary. Current phenomena demonstrate how utopian these conditions are as the judiciary becomes increasingly politically pragmatic, transactional, interdependent, and demoralized. At the same time, phenomenon of constitutional defiance is growing stronger with efforts to deconstitutionalize and politicize the judiciary. This study aims to explore the existence and legitimacy of the judiciary in constitutional democracy era against that phenomenon. The research was conducted doctrinally with a historical, conceptual, and comparative approach that was analyzed qualitatively. The results indicate …

This study highlights the controversy surrounding the change in nomenclature for student workers at Gadjah Mada University, particularly within the Faculty of Law. The status of these workers has shifted from 'part-time' to 'student intern'. This unilateral change has created a legal grey area that could lead to students being subjected to disguised employment practices. Using socio-legal research methods, this article examines the validity of the 'internship' status based on the elements of an employment relationship (work, orders and wages) within the labour law regime, analysing it using the theory of structural injustice. The research findings suggest that reclassifying part-time …


Kedudukan Hukum Eks-Kreditor Pasca Debt To Equity Swap Yang Dihomologasi Dalam Pkpu Kedua Dan Kepailitan Debitor Akibat Pembatalan Perdamaian, Reza Rahmawati Jan 2026

Kedudukan Hukum Eks-Kreditor Pasca Debt To Equity Swap Yang Dihomologasi Dalam Pkpu Kedua Dan Kepailitan Debitor Akibat Pembatalan Perdamaian, Reza Rahmawati

Jurnal Hukum & Pembangunan

Debt to Equity Swap (DES) under a composition plan in Suspension of Debt Payment Obligations (PKPU) proceedings constitutes a restructuring mechanism that transforms the legal status of a Creditor into that of a shareholder upon homologation. Legal issues arise when The Debtor subsequently enters a Second PKPU due to newly incurred debts or is declared bankrupt following the annulment of the composition, while Law No. 37 of 2004 on Bankruptcy and Suspension of Debt Payment does not expressly regulate the legal consequences of a DES under such circumstances. This normative legal research aims to analyze the legal standing and legal …

Maritime transportation plays a vital role in supporting trade, yet risks such as perils of the sea or ship accidents caused by unseaworthiness often lead to disputes, particularly when General Average is declared. This practice, recognized since Roman times, has evolved into a legal concept in marine insurance to distribute deliberate sacrifices made for the safety of the vessel and its cargo. This study aims to analyze the liability of carriers in General Average actions and to evaluate the concept as a fair mechanism for loss distribution. The research employs a normative juridical method with statutory, conceptual, and comparative approaches, …
