Abstract

Increasing greenhouse gas (GHG) emissions from industrial activities have become a serious environmental concern, making carbon sequestration through vegetation an important mitigation strategy, particularly in industrial areas where green open spaces serve as natural carbon sinks. This applied study analyzed the influence of biodiversity on GHG emission reduction through vegetation carbon stock estimation across four strata, namely trees, poles, saplings, and undergrowth, in the Mill area (estimated 10 Ha) and Conservation area (3.52 Ha), using an allometric approach from literature converted into tCO₂e, with statistical analysis conducted using the Spearman correlation test and Kruskal-Wallis test due to non-normal data distribution and small sample size. The highest carbon sequestration was recorded in the tree strata at 147.996 tCO₂e (90.7% of total), while the lowest was recorded in the undergrowth strata at 2.190 tCO₂e in the Mill area, with total sequestration of 163.032 tCO₂e in the Mill area and 20,233 tCO₂e in the Conservation area. The results of this applied study concluded that vegetation effectiveness in reducing GHG emissions is more determined by biomass accumulation rather than species diversity, as evidenced by the dominance of a single species (trembesi) contributing significantly to carbon stocks. Greening strategies should prioritize planting high-biomass vegetation such as trembesi (Samanea saman), mahogany (Swietenia mahagoni), and acacia (Acacia mangium), and be integrated with other emission reduction efforts such as energy efficiency and carbon capture technology.

Abstract

Domestic waste management in the industrial sector requires an effective system, one of which begins with waste sorting at source. This applied study aims to evaluate the compliance of the waste sorting program in the paper industry with existing regulations. The method used is descriptive qualitative through field observations, waste inventory data and literature studies, and refers to applicable regulations. The study results indicate that the waste generated consists of organic, inorganic, and residual waste that has been sorted and managed according to its characteristics. Waste utilization is carried out through processing in the RDF (Refuse Derived Fuel) boiler, maggot feed, and internal and external recycling. This program contributes to increasing management efficiency and reducing waste to the Final Processing Site. Optimization is still needed through increasing consistency of sorting and participation of all parties to support sustainable waste management.

Abstract

Sidoarjo Regency is one of the major administrative regions in East Java that has actively pursued regional development initiatives to strengthen village-based tourism and local economic resilience. One of the strategic approaches adopted by the local government is river revitalization, which is designed not only to restore the ecological and hydrological functions of rivers, including their role as groundwater reserves, but also to enhance their potential as tourism and recreational assets. This approach reflects an integrated development strategy that combines environmental sustainability with community-based economic development. To support the implementation of these programs, the Shipbuilding Institute of Poltytechnic Surabaya (PPNS) has established a formal collaboration with the Sidoarjo Regency Government through the signing of a Memorandum of Understanding. This collaboration provides an institutional framework for PPNS to contribute to regional development through research activities, community engagement, and human resource capacity-building programs. As part of this collaboration, PPNS plays an active role in facilitating the transfer of knowledge and technical expertise to local stakeholders involved in village development initiatives. The river revitalization program has been implemented in several selected locations, including Sumorame Village and Kemantren Village, which have been identified as areas with potential for river-based tourism development. In these villages, PPNS provides academic and technical assistance to support the planning and implementation of river revitalization activities, with a particular focus on improving environmental quality, strengthening community participation, and enhancing the sustainability of tourism development. The findings of this study highlight the importance of institutional collaboration and academic involvement in ensuring the effective implementation of river revitalization as a strategy for sustainable village tourism development.

Abstract

Greenhouse gas emissions from waste management contribute to climate change, including in higher education institutions. This study aimed to evaluate the potential for carbon emission mitigation from waste management at the Politeknik Perkapalan Negeri Surabaya campus through organic waste composting and inorganic waste recycling using a waste bank system. The application of solid waste generation measurement was combined with the Intergovernmental Panel Climate Change guidelines and SNI 3964:2025. A descriptive quantitative approach was employed, utilizing primary data on solid waste characteristics from selected campus buildings. Baseline emission estimates and mitigation scenarios were used, assuming partial implementation of the 3R program: organic waste composting and recycling. The results indicate that the waste management sector produces approximately 5.44 tons of CO₂ per year, and the proposed emission reductions could reduce emissions by approximately 63%. The findings of this study indicate that integrated waste management has significant potential for reducing carbon emissions and supporting the development of low-carbon campuses aligned with Sustainable Development Goals 12 and 13, despite the methodological limitations related to the assumptions of emission factors and the level of implementation

Abstract

In Tanjung Tembaga, Mayangan District, Probolinggo City, this study examines traditional fishermen's interest in adopting floating net cage (FNC) technology for marine aquaculture and how their knowledge, economic conditions, and social factors influence it. Data were obtained from 130 respondents selected purposively. The data were analyzed using multiple linear regression with SPSS version 27, following the quantitative descriptive technique established in the Ecosystem Approach to Fisheries Management (EAFM). Although economic factors did not have a positive and significant effect on interest in FNC adoption, knowledge and social conditions did (t = 3.853; Sig. = 0.000 and t = 3.351; Sig. = 0.001). The R² value of 0.357 proves that these three factors influence the interest variable by 35.7%. The results of this study indicate that interest prior to adoption is more influenced by understanding of fishing regulations, high-value species, community dynamics, and local knowledge than by financial status or asset ownership. To help traditional fishermen transition to sustainable marine aquaculture, this study recommends focusing less on financial assistance and more on enhancing technical knowledge, community engagement, and conflict management.
