Abstract

This research aims to analyze the levels of borax in snacks sold in primary schools (SD) scattered across Lenek Daya Village, West Nusa Tenggara. The sampling method was conducted using purposive sampling from all primary schools in the village, followed by qualitative analysis of borax using turmeric paper. Furthermore, samples indicated positive for containing borax were analyzed for their levels based on the alkalimetric titration method. The results showed that there were 3 samples indicated positive for containing borax, namely sample A1 with a borax level of 819.8 ppm; B1 at 1175 ppm, and sample D1 at 1360.2 ppm. These findings indicate the potential existence of food safety issues among primary school children in Lenek Daya Village. Therefore, steps to enhance supervision and control of food quality in the school environment need to be increased to ensure the safety of children's snack consumption.

Abstract

Bioactive compounds in food have become a central subject of research due to their significant role in promoting health and preventing chronic diseases. This study presents a bibliometric analysis of research trends in bioactive compounds in food from 2015–2025. Data were collected and processed using the Publish or Perish software and Ms. Excel from Google Scholar, applying the keywords “bioactive compounds in food”. VOS-viewer was used to visualize keyword co-occurrence and citation networks. The bibliometric analysis of publications on bioactive compounds in foods generated 340 articles with a steadily growing research interest. The high frequency of studies focused on delivery systems, antioxidant activity, and compound stability underscores a strong emphasis on the practical application and health functionality of bioactive compounds in foods. Thematic clustering highlights diverse research focuses, including marine-based ingredients, plant-derived phytochemicals, functional food formulation, and processing technologies. Overlay and density visualizations further indicate a temporal shift from compound identification and extraction toward application, bioavailability, and health impact studies.

Abstract

The Panimbang River in Pandeglang, Indonesia, is widely used by residents for daily activities. This study analyzed water quality using physical parameters, including pH, temperature, dissolved oxygen (DO), Total Dissolved Solids (TDS), TSS (Total Suspended Solids), salinity, and alkalinity. Samples were taken around the estuary, which is surrounded by settlements. The results showed a pH of 4.50–6.49, below the standard of 6–9, indicating slightly acidic water. High temperatures, thought to be due to daytime sampling, affect DO. The average DO value was only 2.96 mg/L, well below the minimum threshold of 5 mg/L, indicating poor aeration. The average TDS is above 1000 ppm, indicating pollution from household waste and human activities. The average alkalinity of 384.976 mg/L CaCO₃ is within the safe range (30–500 mg/L), so it can stabilize pH. The water quality in the Panimbang River Estuary indicates environmental pressure from anthropogenic activities, resulting in slightly acidic water with low aeration and high solute content. However, adequate alkalinity still helps maintain the water's pH stability. This condition indicates the need for more intensive monitoring and waste management to protect estuarine ecosystems, which are vital to the community and the surrounding environment.
