Abstract

Heavy metals are poisonous materials capable of causing damage to the normal aquatic organisms in the community around the Ketahun River estuary. The entry of heavy metals into the waters of the Ketahun River estuary is allegedly from various activities such as bathing, washing, toilet use, palm oil plantations, coal mining, and the disposal of gold mine waste. This is the background for conducting research to analyze the content of Hg, Cd, Pb, and As in Litopenaeus vannamei in the Ketahun River estuary. The determination of sampling locations was done using a purposive method, and the samples were tested using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The ecology of the river estuary was measured using a thermometer, pH meter, Dissolved Oxygen Meter, and Total Dissolved Solid Meter. The research results were analyzed using a descriptive qualitative method. According to the findings of the study, the metal content in Litopenaeus vannamei exceeds the quality standard with an analysis result of 0.2328 mg/kg, while the quality standard is 0.20 mg/kg, which has health implications. For sediment, the heavy metal that exceeds the quality standard is mercury at 0.5921 mg/kg, while the quality standard is 0.15 mg/kg. The ecology of the river estuary continues to be an ideal environment for living biota.

Abstract

Learning media represents a significant innovation in educational technology, with Nearpod emerging as a valuable tool for enhancing interactive science education in junior high schools. The current generation of students often experiences boredom during traditional learning methods, necessitating the adoption of engaging platforms like Nearpod to facilitate effective material delivery. This study aims to evaluate the application of Nearpod in teaching energy concepts within junior high school science curricula. Employing a Systematic Literature Review (SLR) methodology guided by the PRISMA protocol, this research involved a comprehensive literature search using the Google Scholar database, supported by the Publish or Perish (PoP) application. Out of 386 identified research papers, 11 met the criteria for detailed analysis. The analysis reveals that the integration of Nearpod in junior high school science education is relatively underexplored, especially in topics such as energy. However, findings indicate that Nearpod is an effective medium for fostering engagement, critical thinking, and learning outcomes. These results encourage science educators to incorporate Nearpod into inquiry-based or project-based learning to support more interactive, student-centered instruction. The review is limited to open-access studies conducted in Indonesia between 2015 and 2025, focusing solely on junior high school science education.

Abstract

The use of organic fertilizers is considered to be beneficial by farmers such as increasing land productivity. Corn farming contributes the highest agricultural waste in Indonesia, such as stem litter, leaves and husks. This waste has the potential to be used as organic fertilizer because based on research it contains many nutrients in it. This study aims to evaluate the effectiveness of EM4-based microbial treatment in accelerating the composting of corn litter waste through observational qualitative analysis. The results of this study indicate that the addition of microorganisms can shorten the time to make organic fertilizer. On the 6th day, the corn litter waste sample that had been given EM4 had shown the appropriate criteria for organic fertilizer in the form of a neutral pH concentration of 6.5 and did not have a disturbing odor and a texture that was no longer stiff. These findings suggest that EM4 can be used to accelerate composting of corn waste into high-quality organic fertilizer, potentially supporting sustainable agriculture.
