Abstract

Fucoxanthin has attracted significant public attention due to its extensive bioactive properties, including antioxidant, anti-inflammatory, and anti-obesity effects. This study conducts a bibliometric analysis to assess research trends, key contributors, and scientific progress in fucoxanthin studies. By utilizing data from prominent scientific databases, various bibliometric indicators, such as publication output, citation patterns, and collaborative networks, were analyzed. The analysis reveals a consistent rise in research publications over the past two decades, with significant contributions from countries like Germany, Japan, and China. Additionally, the study identifies leading institutions and influential authors who have significantly impacted the field. The results highlight the expanding interest in fucoxanthin's potential applications in pharmaceuticals, functional foods, and nutraceuticals. Furthermore, the study sheds light on collaborative efforts between academic institutions and industries that drive innovation and commercialization. This comprehensive evaluation not only provides an understanding of the current research landscape but also identifies future directions for scientific exploration and technological advancements. The findings serve as a valuable resource for researchers, policymakers, and industry stakeholders to make informed decisions and foster innovation in the utilization of fucoxanthin for human health and sustainability.

Abstract

Banggai Regency is one of the mining areas in eastern Indonesia. Apart from that, there are also several natural tourist attractions spread across several areas in Banggai Regency, so that the flow of passengers and goods has increased from year to year. The availability of passenger facilities and airport activity services is a critical issue to pay attention to, without adequate facilities, airport service activities will be faced with a risk of meeting user needs. This research aims to determine the strategy for developing terminal facilities at Syukuran Aminuddin Amir Airport based on a combination of internal and external airport factors. The research method uses SWOT analysis with primary data sources in the form of distributing questionnaires and interviews with 100 respondents, as well as secondary data in the form of documents related to terminal facilities from the Airport UPT. The results of the analysis on the SWOT diagram show that the position of the airport is in diagram II, which means that even though it faces several threats, the company still has internal strength. The strategy that must be applied is a diversification strategy in which strength is used to overcome threats

Abstract

Sawdust is an abundant by-product of the wood processing industry and has significant potential as a raw material for biopellet production. However, the quality and combustion performance of biopellets are strongly influenced by the binder concentration used during the production process. This study investigates the effect of binder concentration on the density and combustion performance of sawdust-based biopellets. Biopellets were prepared with binder concentrations of 35%, 40%, and 45% and evaluated through density measurement, bomb calorimeter testing, and combustion analysis. The results show that increasing binder concentration enhances density from 1.16 to 1.26 g/cm³, indicating improved structural compactness. However, the higher heating value (HHV) decreases from 14.44 ± 0.13 MJ/kg to 12.23 ± 0.13 MJ/kg due to dilution of energy-rich biomass. Combustion analysis reveals increased ignition time and longer burning duration at higher binder content, indicating more stable but less reactive combustion. These findings demonstrate a trade-off between mechanical strength and energy performance. Therefore, a binder concentration of 35% is recommended for energy-efficient applications, while higher concentrations may be suitable for durability-oriented uses.

Abstract

Kinerja sistem fotovoltaik sangat dipengaruhi oleh modul suhu permukaan yang berpengaruh terhadap daya keluaran sistem. Penelitian ini bertujuan untuk menganalisis hubungan antara suhu permukaan modul berdasarkan pengukuran kamera termal ( Rata-rata TIR ) terhadap daya keluaran DC sistem PLTS on-grid berkapasitas 2 MWp di PLTS Sumalata. Pengambilan data dilakukan melalui observasi lapangan menggunakan kamera termal untuk memperoleh modul suhu rata-rata permukaan serta data daya DC dari sistem monitoring operasional PLTS selama periode pengamatan bulan November. Data yang diperoleh dijelaskan menggunakan pendekatan grafis untuk mengetahui pengaruh suhu terhadap kinerja sistem. Hasil penelitian menunjukkan bahwa modul suhu permukaan berada pada rentang 45.6 °C hingga 57.3 °C dan peningkatan modul suhu cenderung menyebabkan penurunan kinerja relatif daya keluaran sistem akibat karakteristik koefisien suhu negatif modul fotovoltaik. Hasil penelitian ini menunjukkan bahwa modul suhu permukaan berkontribusi terhadap kehilangan panas sehingga dapat digunakan sebagai parameter evaluasi kinerja operasional sistem PLTS skala utilitas.

Abstract

The transition toward low-carbon energy systems has repositioned biowaste as a strategic resource within the circular bioeconomy, offering potential to enhance resource efficiency, reduce greenhouse gas emissions, and generate value-added bioproducts. This review aims to analyze the relationship between biowaste characteristics and the selection of conversion pathways, evaluate recent advances in conversion technologies, and propose strategies for developing biorefineries that are technically, environmentally, and economically feasible. The study employs a systematic literature review approach, covering foundational and recent studies on pretreatment optimization, biological and thermochemical processes, and the integration of life cycle assessment (LCA) and techno-economic analysis (TEA). The synthesis reveals that no single technology is universally optimal for all types of biowaste; conversion efficiency depends on the alignment between feedstock composition, pretreatment methods, process configuration, and desired end-products. Anaerobic digestion remains the most suitable option for wet organic waste, while thermochemical processes such as pyrolysis and gasification are more appropriate for lignocellulosic biomass. Additionally, emerging approaches involving microalgae, nanotechnology, and machine learning contribute to improving system efficiency and product selectivity. In conclusion, the development of sustainable circular biorefineries requires feedstock standardization, data-driven process design, and the integration of LCA and TEA to support large-scale industrial implementation.
