Abstract

Neuroscience-based learning is a field of neuroscience study that focuses on studying educational concepts from the perspective of the brain's working system. It turns out that teachers and parents still rarely pay attention to this field of study, which has led to the emergence of a learning atmosphere that is passive and not optimal in stimulating nerve cells in the human brain. The results of initial observations carried out on 22-28 April 2021 on high school teachers and students in Tenggarong (SMA Negeri 1 Tenggarong, SMA Negeri 2 Tenggarong, SMA Negeri 3 Tenggarong) showed that there were still many (85%) It was found that teachers still relied on verbal language, image/animation media, PowerPoint and only a few (15%) were varied in their use of biology learning media, although based on interviews they said they understood audio, visual and audiovisual media well enough. Likewise with learning with neuroscience-based media, from the interview results, generally (85%) were not familiar with biology learning with neuroscience-based media and only a few (15%) were familiar with and had implemented it in biology learning. The same thing applies to students' cognitive learning outcomes from interviews that I found that students' abilities were generally moderate and low. This is because students think that biology is a rote subject and are less motivated when learning. This research method is Research and Development (R&D) Sivasailam Thiagarajan. The main objective of this development research method is to produce products and determine the feasibility of products developed in the form of neuroscience-based learning videos which are limited to the circulatory system. The research subjects included four validator experts, namely media experts, materials experts, language experts and learning tools experts. Class XI students as the research sample consisted of two classes, namely the control class and the experimental class. The results of the research show that the validity of learning media is in the valid category (79.95%), the practicality of learning media is in the very good category (83.37%), and also the effectiveness of neuroscience-based learning media in providing a high increase in learning motivation (Gain score = 0 .73) and t test analysis (t count < 0.05) via the SPSS application.

Abstract

Rawa Lake Taliwang is the lifeblood of the West Sumbawa Regency community. The lake is surrounded by extensive agricultural areas, making the activities of local farmers a significant contributor to the accumulation of heavy metals in the region. This study aims to determine the cadmium (Cd) content in snakehead fish (Channa striata ) and assess its suitability for consumption. Sampling was conducted using purposive sampling with direct observation at Lake Rawa Taliwang . Nets or traps were employed at two stations, with two replications at each station. Data analysis involved calculating the cadmium content in the laboratory using Atomic Absorption Spectroscopy (AAS). The results revealed that the cadmium concentration in snakehead fish from Lake Rawa Taliwang was 0.45 mg/kg (ppm). This concentration exceeds the permissible limit for metal contamination in food, as stated in BPOM Regulation Number 9 of 2022. As a result, the snakehead fish is deemed unfit for consumption.

Abstract

The presence of heavy metals in Lake Rawa Taliwang can originate from various activities in the upstream river, around settlements, and within the lake itself. Mercury (Hg) is a highly toxic heavy metal due to its neurotoxic nature, affecting both organisms and humans. One of the fish found in Lake Rawa Taliwang is the swamp eel. Swamp eels are often caught for consumption and cultured by the local community. This study aims to determine the mercury (Hg) concentration in swamp eels (Monopterus albus) and assess their suitability for consumption. Sampling was conducted using purposive sampling technique at two stations with two replications at each station. Data analysis involved determining mercury concentration in the swamp eel samples using Atomic Absorption Spectroscopy (AAS). The results showed that the mercury concentration in swamp eels from Lake Rawa Taliwang was 0.13 mg/kg. According to the BPOM regulation no. 9 of 2022, the mercury concentration in these swamp eels is still below the permissible limit for metal contamination in food. This indicates that swamp eels were taken from Lake Rawa Taliwang is safe for consumption.

Abstract

Production of white shrimp (Litopenaeus vannamei) tends to decrease every year caused by diseases, one of which is White Feces Disease (WFD). Genetically, monitoring has been carried out on the parent characters of SPF (Specific Pathogen Free) shrimp imported from Hawaii and Florida with low genetic variation. If there is a threat such as disease caused by bacteria and the gene that codes for disease control or the body's resistance gene is missing, it allows the individual to become susceptible to disease. Gene that codes for body resistance in white shrimp is hemocyanin. Hemocyanin gene studies are needed as a first step in controlling disease in white shrimp. Method used is a descriptive method. Procedures carried out are sample collection, detection of WFD, molecular analysis of hemocyanin and data analysis. Results showed that healthy shrimp had hemocyanin while shrimp with WFD had very little or no amount of hemocyanin. Hemocyanin gene profile in healthy shrimp was also analyzed and there were 4 nucleotide change made changes to 4 amino acid. Changes in amino acids affect the stability of hemocyanin and cause polymorphism of hemocyanin. Phylogenetic analysis showed dendogram split into two clades between L. vannamei and P. monodon.
