Abstract

Taliwang Swamp Lake is a freshwater ecosystem under pressure from anthropogenic activities, including illegal mining, which has the potential to increase heavy metal contamination. This study aimed to measure Cd concentrations in tilapia in Taliwang Swamp Lake and assess their suitability for consumption based on BPOM standards. Data were analyzed using the Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) method. The results showed that Cd in tilapia ranged from 0.024 to 0.027 mg/kg, with an average of 0.0255 mg/kg, which is still below the maximum threshold of 0.30 mg/kg. Environmental parameters such as temperature (30oC), pH (7.7-7.8), and salinity (10 ppt) were within the ideal range for aquatic life and did not indicate extreme conditions that could increase Cd bioaccumulation. Visual observation of the fish flesh also showed normal color and texture with no indication of tissue damage due to heavy metal exposure. Overall, tilapia from Lake Rawa Taliwang is still safe for consumption, although regular monitoring is still needed to prevent the risk of long-term Cd exposure.

Abstract

Rawa Taliwang is one of the major lakes in West Sumbawa Regency and is vulnerable to mercury (Hg) contamination resulting from surrounding activities such as illegal gold mining, agricultural runoff, and domestic waste disposal. This study aimed to determine the mercury concentration in catfish (Clarias batrachus) inhabiting the lake and to assess its safety for human consumption. Fish samples were collected from two sampling stations using purposive sampling and analyzed in the laboratory using a Mercury Analyzer. The measured mercury concentrations ranged from 0.058 to 0.086 mg/kg, with an average of 0.072 mg/kg, which is below the maximum allowable limit of 0.50 mg/kg set by the Indonesian National Agency for Drug and Food Control (BPOM) Regulation No. 9/2022. These results indicate that catfish from Rawa Taliwang Lake remain safe for consumption. Continued monitoring and improved environmental management are recommended to prevent future increases in mercury contamination and to ensure long-term ecosystem and public health safety.

Abstract

Taliwang Swamp Lake is a source of livelihood for the people of West Sumbawa. High levels of local activity, such as agriculture and mining, have the potential to pollute the lake with mercury (Hg) due to waste from the amalgamation process and fertilizer residues flowing into the lake. This study aims to determine the heavy metal content of mercury (Hg) in snakehead fish (Channa striata) from Rawa Taliwang Lake and its suitability for consumption. Sampling was carried out using a purposive sampling technique at both stations. The criteria for selecting the sampling location were that it could represent the west and east sides of the lake and also take into account the fishing points that could be accessed, considering that the lake was partly covered with vegetation. Data analysis included determining mercury (Hg) levels using a mercury analyzer. The results showed that the mercury (Hg) content in snakehead fish was 0.078 mg/kg. This level is still suitable for consumption according to Food and Drug Supervisory Agency (BPOM) regulation No. 9 of 2022.

Abstract

The development of critical thinking skills is a strategic agenda in biology education, particularly in preparing prospective teachers capable of integrating scientific analysis with real ecological contexts. However, learning that remains oriented towards classrooms and limited laboratories has not fully strengthened students' evaluative and argumentative abilities. Field learning based on M. reinwardt ecotourism offers a contextual approach that places students in authentic observation and analysis situations. This study aims to test the effectiveness of ecotourism-based field learning in improving the critical thinking skills (CTS) of Biology Education students. The study used a quasi-experimental pretest–posttest control-group design. The experimental group implemented the Ecotourism-Based Field learning Model (EBFL) by studying the ecology and conservation of M. reinwardt in the Gunung Tunak and Kerandangan Nature Tourism Parks, while the control group followed a conventional laboratory practicum. The research instrument was a CTS test validated by experts, and the model's effectiveness was analysed using N-Gain and the Mann–Whitney test. The results showed a significant difference in CTS improvement between the experimental and control groups, as well as a substantive influence of field learning on higher-level cognitive achievement. These findings strengthen the development of an ecotourism-based contextual science learning model as a pedagogical innovation in the education of prospective biology teachers.

Abstract

Introduction: Hypertension is defined as an elevation in blood pressure beyond the normal limit, specifically exceeding 140/90 mmHg. The increase in blood pressure is attributed to indirect causes related to dietary habits and lifestyle, leading to a deficiency in knowledge. A knowledge deficit refers to a lack of cognitive information or non-adherence to recommended dietary and lifestyle modifications. Consequently, educational interventions are implemented to enhance understanding of appropriate lifestyle and dietary patterns. One non-pharmacological therapy that may be provided is education on the DASH (Dietary Approaches to Stop Hypertension) diet. This study aim was to provide an overview of DASH (Dietary Approaches to Stop Hypertension) education for hypertensive patients with the nursing diagnosis of knowledge deficit, by offering a clearer understanding of the importance of DASH (Dietary Approaches to Stop Hypertension) in hypertensive patients. Method: A descriptive design was used, which is a design intended to improve a knowledge deficit. Results: There was an effect on the knowledge deficit, resulting in an increase in knowledge and a change in blood pressure. This was evidenced by Client 1, who was able to answer 8 questions correctly on the questionnaire, with a percentage indicating 'Good,' while Client 2 was only able to answer 6 questions correctly, with a percentage indicating 'Fair,' due to factors such as age, education, and environment. Both clients appeared to understand the low-salt diet, and their blood pressure improved. Conclusion: Based on the results of the study involving two respondents, there was an effect on their knowledge deficit regarding DASH (Dietary Approaches to Stop Hypertension) as well as a change in their blood pressure.
