Abstract

Jelawat fish (Leptobarbus hoevenii) are found in several rivers in Kalimantan and Sumatra. Often encountered obstacles in fish farming is the bacterial disease Aeromonas hydrophila, known as Motile Aeromonas Septicemia (MAS). Treatment of disease can use natural ingredients that function as antimicrobials. Papaya seeds contain antimicrobials; besides that, they also contain secondary metabolites such as phenols, terpenoids, alkaloids, and saponins. The terpenoid group is the main component of papaya seeds and has antibacterial activity. This study aims to determine the effectiveness of the best papaya seed extract on the survival of jelawat fish infected with Aeromonas hydrophila bacteria. The treatment in this study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments were treatment A (soaking with papaya seed extract at 0 ppm), treatment B (soaking with papaya seed extract at 40 ppm), treatment C (soaking with papaya seed extract at 80 ppm), and treatment D (soaking with papaya seed extract at 120 ppm). The results showed that the administration of papaya seed extract by immersion had a significant effect on the response to high feeding, with an average absolute weight growth value of 1.33 grams, a 100% survival rate, and wound healing in sharks infected with A. hydrophila bacteria starting to normalize or heal. Meanwhile, the water quality observed during the study was quite supportive for the survival of the jelawat, with temperatures ranging from 27–28, dissolved oxygen (DO) ranging from 7-8.7 mg/L, pH ranging from 6.5 to 7.3, and ammonia values from 0.1–0.3 mg/L. Giving 80 ppm through soaking papaya seed extract with jelawat fish is the best.

Abstract

Onventional teaching media used by teachers in teaching chemical bonding has not been able to facilitate students in understanding the concept of chemical bonding because the media used are still in two-dimensional form. Therefore, it is necessary to develop three-dimensional teaching media capable of visualizing the concept of chemical bonding, one of which is augmented reality (AR). This study aims to determine the validity and practicality of an AR-based chemical bonding module. The research type used is Borg and Gall's development research model, modified into 7 research stages. The research sample consisted of 30 students selected using purposive sampling technique. The results of material, media, and language validation analysis indicate that the developed AR-based module is valid with validity percentages of 96.66%, 81.47%, and 88.33%, respectively. Practicality analysis using a practicality questionnaire shows that the developed AR-based module is practical with a practicality score of 93.88%. Therefore, the AR-based module is highly suitable as an alternative teaching media for the topic of chemical bonding

Abstract

The adsorption of Methylene Blue (MB) dye from aqueous solutions using natural adsorbents derived from Gamalama volcanic soil was investigated in this study. The adsorbent materials were characterized by FTIR, X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) analyses, confirming the presence of allophane, halloysite, and kaolinite, which exhibit different morphologies and surface properties. Batch adsorption experiments were conducted to evaluate the effects of pH, contact time, and adsorbent mass on the removal efficiency of Methylene Blue. The results demonstrated that Gamalama volcanic soil adsorbents have a high affinity for Methylene Blue, achieving significant removal rates under optimal conditions. The findings suggest that Gamalama volcanic soil is a promising, low-cost, and environmentally friendly adsorbent for treating dye-contaminated wastewater. This study highlights the potential application of natural volcanic soil as an effective adsorbent in environmental remediation. The optimum MB removal was performed by adsorption condition with pH 6, 20 minutes contact time and 30 mg adsorbent.
