Penelitian ini bertujuan untuk menganalisis model penguatan daya saing produk perikanan melalui pendekatan sistem agribisnis berbasis inovasi pemasaran dan efisiensi saluran distribusi berdasarkan sintesis literatur ilmiah terkini pada bidang agribisnis perikanan. Metode yang digunakan adalah studi literatur sistematis terhadap publikasi ilmiah yang diperoleh dari berbagai data referensi artikel ilmiah nasional dan buku referensi bidang dengan fokus pada aspek pemasaran, kewirausahaan perikanan, distribusi hasil perikanan, inovasi agribisnis, dan penguatan kapasitas pelaku usaha sektor perikanan. Analisis dilakukan menggunakan pendekatan tematik sintesis konseptual untuk mengidentifikasi pola strategi penguatan daya saing produk perikanan. Hasil kajian menunjukkan bahwa daya saing produk perikanan dipengaruhi oleh integrasi subsistem agribisnis, efisiensi saluran pemasaran, inovasi digital marketing, penguatan kelembagaan usaha, serta peningkatan kompetensi kewirausahaan pelaku usaha perikanan. Model konseptual yang dihasilkan menegaskan bahwa sinergi antara inovasi pemasaran, efisiensi distribusi, dan penguatan kapasitas usaha menjadi faktor utama dalam meningkatkan nilai tambah dan posisi kompetitif produk perikanan. Implikasi penelitian ini memberikan dasar strategis bagi pengembangan kebijakan agribisnis perikanan berbasis sistem pemasaran terintegrasi.

Abstract

This article presents a comprehensive Systematic Literature Review (SLR) of cutting-edge advancements in solar energy technology, mapping the paradigm shift from single-component efficiency to multi-functional system integration. Utilizing a data corpus from JREE and PLTS comprising high-repute publications from the 2023–2026 period, this study identifies five primary innovation clusters: (1) optimization of photovoltaic (PV) systems and perovskite solar cells; (2) integration of thermal energy storage utilizing Phase Change Materials (PCM); (3) hybrid solar drying applications for the agro-industrial sector; (4) desalination technologies based on interfacial evaporation; and (5) smart building implementation via data-driven control systems. In response to critical reviews, this article strengthens its methodological foundation by providing technical justification for selecting the data corpus, ensuring it is representative of global trends, and mitigating the limitations of abstract-based analysis through an in-depth examination of key studies. Specific focus is placed on the role of Artificial Intelligence (AI), as this review transitions from a descriptive narrative to a systematic analysis of the requirements for interpretable and robust models in system monitoring. The analytical results indicate that the synergy between advanced materials such as nanofluids and metamaterials—and multi-objective optimization algorithms is pivotal to achieving decarbonization targets. Overall, this review provides a roadmap for researchers in developing solar systems that are not only technically efficient but also economically viable and sustainable, supported by a comprehensive reference list that reinforces the reliability of this data synthesis.

Abstract

Solar Power Plants (PLTs) are among the main pillars of Indonesia's renewable energy transition, especially in regions with high solar irradiation potential, such as Gorontalo. This study aims to evaluate the operational performance of the 2 MWp PLTS in Sumalata by calculating the Capacity Factor (CF). The data used includes monthly energy production and solar irradiation during the 2024 operational period. The research method is descriptive-quantitative, calculating the ratio between actual energy output and maximum installed capacity. The results showed that the highest energy production occurred in September at 247,640 kWh, while the lowest was in December at 124,200 kWh. The average Capacity Factor obtained was 15.03%. This value is significantly influenced by weather fluctuations, cloud cover, and solar panel cleanliness (soiling). Although the CF value is within the standard range for PLTS in tropical regions, optimization in preventive maintenance and regular panel cleaning is required to improve system efficiency. This study concludes that the Sumalata PLTS makes a vital contribution to the regional energy mix, but its efficiency remains highly dependent on local meteorological conditions.

Abstract

This study examines the effect of different surfactants: Cetyltrimethylammonium Bromide (CTAB), Didodecyldimethylammonium Bromide (DDAB), and Methyltrioctylammonium Bromide (MTAB) on the synthesis of mesoporous TiO2 using the co-precipitation method. Characterization was performed using Raman Spectroscopy, BET (Brunauer-Emmett-Teller) surface area measurement, Differential Scanning Calorimetry (DSC), and X-ray Diffraction (XRD) techniques. The results indicate that the highest surface area was achieved by CTAB 98.32 m2/g, while MTAB yielded the greatest pore volume 0.2517 cc/g and the largest average pore diameter 10.498 nm. Furthermore, a simple catalytic activity test was performed through the degradation of methylene blue under UV irradiation, which showed that the TiO2–MTAB sample had the highest degradation rate of 0.032 min-1. This indicates a positive correlation between pore size and photocatalytic efficiency.

Abstract

Water hyacinth (Eichhornia crassipes) is simultaneously an invasive aquatic burden and a potentially valuable lignocellulosic feedstock for agricultural materials. This review critically evaluates its material potential through a structured synthesis of 51 studies supplied in the source corpus, spanning direct water-hyacinth evidence and transferable findings from agricultural residues, biochars, cellulose derivatives, hydrogels, films, composites, adsorbents, and thermal-storage systems published mainly during 2021-2026. The evidence is organized around feedstock variability, physical architecture, chemical composition, thermal conversion, and application-specific structure–property relationships. Direct evidence confirms that water-hyacinth biochar can reduce thermal conductivity and volumetric heat capacity in soil blends, but the corpus lacks standardized datasets for untreated plant fractions, seasonal composition, contaminant burdens, and long-term field performance. Cross-biomass studies show that alkali treatment, bleaching, hydrolysis, silane modification, pyrolysis, activation, and hybridization can convert low-density plant tissue into cellulose fillers, nanocellulose, porous carbon, controlled-release matrices, insulation products, and functional coatings. The synthesis indicates that water hyacinth is most credible as a locally processed feedstock for biochar-based soil systems, sorbents, water-retentive composites, biodegradable films, low-load panels, and thermal-management components. Its high moisture burden, hydrophilicity, heterogeneous ash and mineral content, and potential accumulation of pollutants remain decisive constraints. A design framework is proposed that links plant fraction, pretreatment severity, porosity, surface chemistry, crystallinity, and thermal stability to agricultural function. Future progress requires fraction-specific characterization, contaminant-safe harvesting, low-energy dewatering, benchmarked life-cycle assessment, release and leaching tests, field validation, and standards that distinguish direct water-hyacinth data from analogical inference for circular and climate-resilient agricultural production systems.
