Abstract

Surfactant which is used as raw emulsifier in an industry activity such as Sodium Lauryl Sulfonate is a raw material import, it is petroleum derivative which is not renewable and may cause pollution to the environment, because it is not degraded and are carcinogenic. The purpose of the research is to compare the characteristics of the Quaternary methyl ester sulfonat (MES) and Sodium Lauryl Sulfonat (SLS) as emulsifier. First, make the MES by filtering and eliminating fatty acids of palm oil, then process the MES with enzymatic method become methyl ester, then react it in sulfonation and metanolization process, and also neutralized with NaOH. Next, the MES experiment is compared with SLS and existing MES in the market. The results show that surfactants MES experiment has value hidrofil lipofil balance (HLB) interfacial tension and emulsion stability greater than MES in the market and SLS. And the surface tension of MES experiment is larger than MES in the market, but smaller compared to SLS.ABSTRAKSurfaktan yang digunakan sebagai bahan baku emulsifer dalam aktivitas suatu industri pada saat ini seperti Sodium Lauril Sulfonat  merupakan bahan baku import yang merupakan turunan dari minyak bumi, dengan sifat tidak dapat diperbaharui dan dapat menimbulkan pencemaran terhadap lingkungan karena tidak mudah terdegradasi serta bersifat karsinogenik. Metil ester sulfonat dari bahan minyak sawit merupakan surfaktan dengan sifat mudah terdegradasi yang perlu diketahui karakteristiknya. Penelitian bertujuan untuk membandingkan karakteristik surfaktan metil ester sulfonat (MES) dan Sodium Lauril Sulfonat (SLS) sebagai bahan emulsifier. Mula-mula dilakukan pembuatan MES dengan cara menyaring dan menghilangkan asam lemak minyak sawit terlebih dahulu, kemudian diolah menjadi metil ester secara enzimatis, lalu direaksikan secara sulfonasi dan metanolisis, serta dinetralkan dengan NaOH. Selanjutnya MES hasil percobaan dibandingkan dengan SLS dan MES yang ada dipasaran. Hasil penelitian menunjukkan bahwa surfaktan MES memiliki nilai hidrofil lipofil balance (HLB) tegangan antar muka dan stabilitas emulsi lebih besar apabila dibandingkan dengan MES di pasaran dan SLS, kecuali nilai stabilitas emulsi antara MES dan SLS sama. Dan tegangan permukaan MES hasil percobaan, lebih besar dibandingkan dengan MES dipasaran, dan lebih kecil dibandingkan dengan SLS. Kata kunci :   Metil  ester sulfonat, hidrofil lipofil balance, emulsifier, sodium lauril sulfonat , stabilitas emulsi

Abstract

This study investigates the transformative potential of blockchain-enabled information systems for transparent greenhouse gas (GHG) reporting in maritime training organizations, addressing critical gaps in regulatory compliance and environmental accountability. Through qualitative thematic analysis of in-depth interviews with five maritime education professionals, this research examines how distributed ledger technology can revolutionize compliance with emerging EU regulations, including FuelEU Maritime directives and EU Emissions Trading System (ETS) requirements, alongside International Maritime Organization (IMO) standards. The study reveals that blockchain technology offers unprecedented solutions to longstanding challenges in maritime education systems, particularly in transparency, verification accuracy, and cross-organizational interoperability. Key findings highlight the technology's capacity to enable smart contract automation for real-time compliance monitoring, create immutable credentialing systems that enhance trust among stakeholders, and establish secure, tamper-proof records of seafarer competency development and environmental certification processes. Results demonstrate that blockchain-based systems can significantly strengthen the integrity of maritime training records while streamlining regulatory reporting processes.

Abstract

Coastal communities worldwide face unprecedented livelihood threats as 680 million inhabitants experience declining fish stocks, climate change impacts, and economic marginalization despite residing adjacent to valuable marine resources. This research develops a comprehensive Blue Economy Literacy Framework integrating marine conservation education, maritime entrepreneurship training, and cultural heritage preservation to enable sustainable coastal socio-economic development. Through qualitative analysis incorporating perspectives from marine biologists, community development specialists, and coastal education practitioners, this study identifies critical curriculum components, pedagogical approaches, and implementation barriers constraining coastal capacity building initiatives. The framework synthesizes marine biology, social sciences, economics, and educational pedagogy, demonstrating how multidisciplinary literacy programs can simultaneously enhance environmental stewardship, economic opportunity creation, and cultural identity preservation while addressing power asymmetries and gender inequities prevalent in coastal societies. Findings reveal significant gaps in current coastal education approaches, particularly regarding integration of traditional ecological knowledge with scientific marine conservation principles and connection of environmental protection with livelihood generation strategies. The research contributes actionable implementation pathways for coastal stakeholders globally, offering evidence-based strategies for transformative education aligned with SDG 14 (Life Below Water) and SDG 1 (No Poverty), while empowering marginalized coastal populations through knowledge, skills, and agency essential for sustainable coastal futures.

Abstract

Coastal port cities face unprecedented challenges from climate change, urbanization pressures, and maritime traffic intensification, threatening both urban sustainability and maritime operational efficiency. This research develops a comprehensive Smart Port-City Integration Framework employing GIS-based spatial analysis and predictive modeling to address sea-level rise adaptation, traffic congestion mitigation, and land-use optimization. Through qualitative analysis incorporating perspectives from urban planning experts, maritime infrastructure specialists, and port authority administrators, this study identifies critical integration strategies balancing environmental resilience with economic vitality. The framework synthesizes civil engineering principles with sustainable urban planning methodologies, demonstrating how coastal cities can transform port-urban interfaces into climate-adaptive, economically productive, and socially equitable spaces. Findings reveal significant gaps in current planning approaches, particularly regarding climate risk assessment integration and stakeholder coordination mechanisms. The research contributes practical implementation pathways for port cities globally, offering evidence-based strategies for sustainable coastal development aligned with SDG 11 (Sustainable Cities) and SDG 13 (Climate Action), while enhancing maritime competitiveness through intelligent infrastructure design and resilient spatial planning frameworks.
