Abstract

Introduction: Coastal environmental pollution is one of the biggest challenges for communities whose livelihoods depend heavily on marine resources. Kabaena Island, particularly Baliara Village, faces increasing pollution pressure due to nickel mining activities, unmanaged domestic waste disposal, and intensive fishing vessel operations. This study aimed to analyze the relationship between environmental pollution factors and heavy metal levels in Katamba fish (Lethrinus nebulosus),  Method: This research employed a quantitative analytic approach with a cross-sectional design. A total of 97 respondents were selected using purposive sampling. Data were collected through structured questionnaires as well as fish and seawater samples, which were analyzed in the laboratory using Atomic Absorption Spectrophotometry (AAS) and ICP-OES. Data analysis was conducted using Spearman correlation to examine the association between environmental pollution activities. Result: The results showed that heavy metal concentrations in Katamba fish mostly exceeded the safe consumption limits set by WHO and Government Regulation No. 22/2021. Mining activities were significantly associated with Ni levels (r = –0.200) and seawater pollution (ρ = 0.438). Domestic waste exhibited a significant correlation with Pb levels in fish (r = 0.669), while fishing vessel activities were associated with Cd levels (r = 0.317). These findings highlight the substantial contribution of human activities to increasing heavy metal pollution in coastal areas. Conclusion: There is a relationship between environmental pollutants such as mining activities, domestic waste and fishing boat activities with heavy metal levels such as Hg, Ni, Pb and Cd in seawater and catamba fish.

Abstract

The principle of deliberation and consensus is the spirit of the Pancasila industrial relations system in Indonesia, which aims to create a balance between workers' rights and the sustainability of employers' businesses. This study aims to analyze the legal transformation of the deliberation and consensus mechanism in resolving industrial relations disputes, starting from the era of Law Number 22 of 1957 to Law Number 2 of 2004 (the PPHI Law). The research method used is normative or doctrinal legal research with a statutory approach and library research. The results show that in the era of Law No. 22 of 1957, the dispute resolution mechanism was authoritative, where the state through P4D/P4P dominated the final decision and placed deliberation only as an administrative formality. In contrast, after the enactment of the PPHI Law, there was a paradigm shift towards an autonomous-participatory system that requires bipartite negotiations as an absolute requirement before litigation. However, this implementation still faces challenges in the form of unequal bargaining power and issues of good faith that often trigger "forced consensus." This study concludes the need for a reconstruction of norms that allow law enforcement to test substantive good faith in the bipartite process to realize harmonious social justice for the world of work in Indonesia.

Abstract

Mi basah merupakan makanan berbahan dasar tepung terigu yang sangat populer. Pemakaian tepung terigu pada mi basah dapat disubstitusikan dengan bahan lain diantaranya umbi talas. Tujuan penelitian ini untuk mengetahui formulasi terbaik antara tepung terigu dan umbi talas kukus agar dihasilkan mi basah yang dapat diterima oleh konsumen. Hasil penelitian menunjukkan bahwa perlakuan dengan penambahan umbi talas berpengaruh nyata terhadap kadar air, cooking time, warna dan tekstur. Perlakuan terbaik dimiliki oleh substitusi 10% umbi talas kukus. Sifat fisikokimia mi basah umbi talas memiliki rata-rata kadar air 28,46%, abu 0,82%, protein 9,29%, cooking loss 2,88% dan cooking time 5,32 menit. Hasil analisis hedonik terbaik yaitu warna 3,92 (suka), tekstur 3,76 (suka), rasa 3,52 (suka).Kata kunci: mi, substitusi, talas
