Abstract

Background: Drug development is a process aimed at creating new drugs with enhanced biological activity through various approaches. One such approach is the rational design of new compound candidates using computer-based or in silico modeling technologies, such as molecular docking. Pyruvic acid is known to possess various pharmacological activities, including antioxidant and anti-inflammatory effects. Derivatives of pyruvic acid have the potential to be developed as candidate analgesic and anti-inflammatory drugs. This study explores the in silico development and evaluation of pyruvic acid derivatives as potential analgesic and anti-inflammatory drug candidates. Methods: Drug-likeness was evaluated using Lipinski's Rule of Five via pkCSM, while pharmacokinetic and toxicity profiles were predicted using the same platform. Molecular docking was performed on the cyclooxygenase-2 (COX-2) enzyme (PDB ID: 5IKR) using Molegro Virtual Docker 6.0. Findings: All test compounds met drug-likeness criteria. Compounds H6, H8, H9, H11, H17, and H18 exhibited superior binding affinities compared to paracetamol. Several compounds, including H8 and H10, demonstrated lower predicted toxicity compared to paracetamol. All test compound exhibits favorable pharmacokinetics properties based on the pkCSM preditive model. Conclusion: From this results, compound H6 and H8 emerged as the most promising candidate, exhibiting optimal characteristics across all evaluated parameters. These findings support further development of H6 and H8 as potential analgesic and anti-inflammatory agent targeting COX-2 Inhibition. Novelty/Originality of this article: This study developed and evaluated pyruvic acid derivative compounds as novel analgesic and anti-inflammatory agents based on in silico studies.

Abstract

Background: The Maleo (Macrocephalon maleo) is a Sulawesi-endemic bird with high conservation concern due to habitat degradation and population decline. The Panua Nature Reserve is a key Maleo habitat in Gorontalo Province, yet lacks updated data on habitat use and distribution patterns. This study aims to analyze Maleo presence in nesting grounds, evaluate habitat utilization, predict its distribution, and provide conservation recommendations. Methods: The research used direct surveys via camera traps and spatial modeling using the Maximum Entropy (MaxEnt) algorithm. Data were collected over five months, and analysis included the Relative Abundance Index (RAI) and occupancy modeling to assess habitat suitability and species detection. Finding: Maleo nesting pairs increased by 68.52% from 2022 to 2023. The species exhibited bimodal daily activity (peaks at 06:00–09:00 and 16:00–18:00), with habitat preference for geothermal zones and coastal forests. The RAI was 9.33%, and occupancy rate was estimated at 55%. MaxEnt modeling revealed 7,544.78 ha of highly suitable habitat, concentrated in grids N10, J13, K14, and M09, with an AUC of 0.826, indicating high predictive accuracy. Conclusion: Maleo birds in Panua Nature Reserve are showing a positive nesting trend. However, habitat fragmentation and human activities continue to threaten their sustainability. Strategic management is needed to maintain habitat integrity and support species conservation. Novelty/Originality of this article: This study integrates field-based camera trap data with predictive spatial modeling to provide a comprehensive habitat suitability analysis for the endangered Maleo in Panua Nature Reserve—an approach not yet applied in this location. The findings offer actionable conservation insights and prioritize critical zones for protection.

Abstract

Background: Fruits are one of the leading agricultural commodities in Indonesia, with abundant availability and high consumption rates. Improper fruit storage can cause fruits to spoil quickly and increase organic waste. Sugarcane bagasse waste is one of the largest contributors to organic waste in Indonesia's agricultural sector. On the other hand, avocado seeds are often considered waste because people generally only consume the fruit flesh and discard the seeds without utilizing them. Both types of waste have the potential to be used as biodegradable and environmentally friendly edible coatings for fruits. This scientific study aims to explain the edible coating made from sugarcane bagasse and avocado seeds fortified with moringa leaves as an innovation in addressing issues in the food industry, particularly regarding the quality of fruit flesh that easily spoils due to improper packaging. Methods: The edible coating was produced through the extraction of sugarcane bagasse, avocado seeds, and moringa leaves, followed by homogenization for coating preparation. The edible coating can then be applied to the fruit. The writing method used in this scientific work is based on literature studies from data and information obtained through books, scientific journals, and several relevant sources. Findings: The results indicate that edible coating based on sugarcane bagasse waste has the potential to maintain fruit quality because it contains approximately 40-50% cellulose, which can be used as a base material for natural biopolymers in edible coating. The addition of avocado seeds acts as an antibacterial, antioxidant, starch, and lipid to form a strong, flexible, and water-resistant edible coating structure. The addition of moringa leaves acts as a fortifier for the fruit. Conclusion: The development of edible coatings based on sugarcane bagasse waste and avocado seeds will create an innovative fruit wrapper that preserves fruit quality and is environmentally friendly. Novelty/Originality of this article: Edible coatings on the market generally focus only on the wrapping layer to protect the fruit, without considering the nutritional content of the fruit, which decreases over time. Fortifying edible coatings with moringa leaves can help maintain and enhance fruit nutrients while preventing nutrient loss due to oxidation. This innovation is integrated with barcode technology to provide information about the advantages of edible coatings based on sugarcane bagasse and avocado seeds fortified with moringa leaves.

Abstract

Background: Shrimp farming in the southern coastal areas of Java has expanded rapidly due to increasing global demand, contributing significantly to local economic growth. However, this development has generated ecological degradation and social inequality, including water pollution, mangrove loss, and uneven resource distribution. Addressing these challenges requires balancing economic benefits with environmental and social sustainability. Methods: This study employed a qualitative literature review, analyzing five scientific sources on the impacts of shrimp farming on ecotourism, water quality, mangrove ecosystems, and socioeconomic conditions in Bantul, Kulon Progo, and Kebumen Regencies. Results: The analysis reveals that while shrimp farming enhances local incomes and can support ecotourism, unmanaged practices lead to ecosystem damage, water pollution, and heightened social disparities. Integrated management combining eco-friendly technologies, mangrove rehabilitation, waste treatment, and community empowerment is essential for sustainable development. Conclusion: Sustainable shrimp farming in Java’s coastal regions requires strict zoning, continuous monitoring, and policies that integrate environmental protection with community participation. Long-term development must prioritize economic productivity without sacrificing coastal ecosystem integrity. Novelty/Originality of this article: This study uniquely combines ecological and social perspectives, highlighting shrimp farming’s dual role.

Abstract

Background: As an effort to reduce current climate change, conservation measures such as carbon stock measurements are needed. Tea plants are a suitable commodity for transforming towards low carbon production because perennial plants such as can absorb and store more carbon than seasonal agricultural crops. Methods: Sampling was carried out using a random sampling method that was taken randomly to represent a population for each block number. Data collection for the study was carried out by taking 3 soil and plant samples at each age of the tea plant with an age of 10 years, 30 years, 40 years, and 100 years. The plant samples taken were leaves, stems, roots, and litter. The soil samples taken were soil with a depth of 0-10 cm, 10-20 cm, and 20-30 cm with disturbed and undisturbed soil sampling. Findings: The total carbon stock value of tea plants stored in the Pemandangan Block UP Tambi is 63.17 tons/ha in 10-year-old tea plants; 67.26 tons/ha in 30-year-old tea plants; 67.87 tons/ha in 40-year-old tea plants; and 69.40 tons/ha in 100-year-old tea plants. The NDVI value obtained has a range of 0.384 - 0.557 which does not really reflect the actual age of the plant because of the process of pruning tea plant shoots which is carried out every four years. This results in the spectral radiation of tea plant vegetation even though the age of the plant is very different. Conclusion: The Pemandangan Block of the Tambi Plantation Unit contains tea plants aged 10, 30, 40, and 100 years with an NDVI range of 0.384 to 0.557, where satellite-derived vegetation indices do not represent actual plant age due to replanting and pruning, making them unsuitable for soil carbon stock estimation. Novelty/Originality of this article: This study offers novelty by integrating field-based carbon stock measurements of tea plants with variations in plant age and Sentinel-2A remote sensing analysis, providing a unique contribution to understanding the relationship between soil properties, biomass, and carbon storage capacity in tea plantations, which has not been extensively explored in previous research.
