In general, anchovy is marketed in dried form in almost all traditional markets. The quality of marketed fish changes based on space and time. The purpose of this research is to determine the quality of dry salted anchovy ( Stolephorus sp .) based on organoleptic tests and formalin content at the Sawojajar market. The method used is a case study. Samples were taken randomly at the Sawojajar market, then tested at the Cirebon KIPM Station laboratory. Data analysis was carried out by comparing the results of formalin and organoleptic tests according to SNI 2346-2015 on dried salted anchovy. The results showed that all samples did not contain formalin and the organoleptic test showed that the value in sample I was 5 in II and III, the same value was 6. The organoleptic value of the three samples of salted dried anchovy was still below the SNI threshold, while the organoleptic value of salted dried anchovies was 7 (SNI 23462015).

The sustainability of capture fisheries management is determined by the relationship between important dimensions such as ecological, socio-economic, technological, as well as legal and institutional dimensions. Sustainability in capture fisheries management has urgency in the lives of fishing communities, the interests of the state as well as in the framework of sustainable development including in meeting consumption needs at various levels of society. This study aims to: 1) Determine the status of capture fisheries through the Multidimensional Scaling (MDS) approach. 2) Analyze policies to support capture fisheries at the research site. Data was collected through direct interviews with respondents through questionnaires. The data collected is data on ecological, socio-economic, technological, legal and institutional aspects. This research method uses a Multi-dimensional Scaling (MDS) approach on the ecological, socio-economic, technological, legal and institutional dimensions with the Rapfish technique. The results of the analysis of sustainable capture fisheries management in the city of Tegal based on five main dimensions were obtained for the Ecological dimension of 40.25% (less sustainable), the Economic dimension of 54.96% (Moderately sustainable), the Social dimension of 10% (Enough sustainable sustainable), ), the Technological Dimension of 51.20% (Moderately sustainable), and the Institutional dimension of 50.03% (Moderately Sustainable).

Energy consumption conservation is a hot topic in a wireless sensor network (WSN). The popular algorithm to solve the problem involves reducing communication range using the cluster method, and the low energy adaptive clustering hierarchy (LEACH) is one of the most famous techniques. The cluster based wireless sensor network experiences a heavy intra cluster interference caused of imperfect power control, which can deteriorate the network lifetime. The existing power control technique applies a distance-based power control to select transmission power, which cannot adapt to environmental changes; that is why the network failed to control the interference and calling for a new method to improve the existing power control. The research evaluates the reinforcement learning (RL) based power control that can bring the sensor to select the lowest transmission power while keeping the signal and interference to noise ratio (SINR) of sensor in cluster head (CH) above the threshold. To improve the RL-based power control, the author proposes a dual policy technique with SINR as a control metric. Finally, the simulation exhibits the proposed algorithm's effectiveness and performance improvement over the original one that is network lifetime, packet delivered, and average energy consumption per round.

Research results show: 1) The PINTER mathematics learning model is effective for improving students' high-level thinking skills on algebra material, 2) The PINTER mathematics learning model is practically or easy to apply by teachers, 3) the PINTER mathematics learning model gets good responses from students. Thus, PINTER's mathematics learning model has the potential to be applied to mathematics learning, especially in efforts to enhance higher-order thinking skills.

Scientific modeling is a fundamental tool in STEM education that facilitates the understanding and explanation of complex phenomena. This study examines the effects of the STEM Modelling Design Thinking (STEM MDT) compared to the STEM Project Based Learning (STEM PjBL), particularly in the context of Education for Sustainable Development (ESD), in enhancing students' scientific modeling skills. Using a quasi-experimental design with non-equivalent pre-test and post-test control groups, the study involved 108 ninth-grade students in the experimental group (55 students) who participated in the STEM MDT, while the control group (53 students) engaged in STEM PjBL. Data were collected by evaluating scientific modeling skills before and after the intervention. The results indicated that the STEM MDT significantly improved students' scientific modeling skills, with effect sizes ranging from moderate to very large (Cohen’s d = .91), compared to moderate improvement (Cohen’s d = .43). These findings suggest that integrating ESD within the STEM MDT framework not only enhances scientific modeling competencies but also equips students to address complex real-world challenges. This study highlights the potential of STEM MDT as an innovative pedagogical approach for educators and policymakers seeking to cultivate essential skills in future generations.

This research focuses on prospective teachers who are a group that has a key role in teaching mathematics to future generations. A qualitative approach with an ethnographic design is used to understand and explain the culture and social life of a region by relating its role as a learning resource to developing local culture-based mathematics learning plans. This research method involves collecting data through observation, interviews, and analysis of cultural artifacts. We integrate these cultural elements into mathematics instructional planning. The results of this research show that through exploring local culture, it can be used as a reference for developing learning plans to increase mathematical literacy. Cultural studies as a learning resource are not only for instilling concepts but beyond that, they can be used to develop students' problem solving and critical thinking skills. This research underscores the importance of innovative approaches in mathematics teaching that utilize local cultural assets. The integration of cultural artifacts not only improves mathematical literacy, but also promotes the preservation of cultural heritage. The results of this research can be a guide for educational institutions and teachers in developing mathematics learning strategies that are more contextual and meaningful.

Environmental damage is a severe problem in Indonesia. Efforts to educate the community, especially students, on ecological damage need to be carried out through education. Education must ensure students have the knowledge and awareness to preserve the environment. One uses folklore as a teaching material loaded with ecological wisdom in learning. This research aimed to find and explain the ecological wisdom contained in folklore. The research design used was qualitative research employing a literary ecology approach to analyze aspects of ecological knowledge in folklore. The ecocriticism approach described ecosystem elements, environmental wisdom, and forms of ecological damage in folklore. The research results showed that based on 40 works folklore from Central Java narrated ecological wisdom through the relationship between humans and nature from two perspectives: nature as a subject and nature as an object. The protagonists who positioned nature as the mother, ethics of life, and nature’s holistic nature represented the relationship between nature and humans as subjects. Meanwhile, the relationship between humans and nature as antagonists in acts of exploitation and violence against the environment represented objects. The presence of these two relationships allowed readers to understand the concept of ecological wisdom in folklore. Thus, Central Java folklore could be used as learning material in elementary schools to internalize values of environmental wisdom in students.

Sustainable emulsions rely on interfacial materials that are efficient, suitable for food applications, and environmentally friendly. This review connects two distinct but complementary areas: (1) the trophic interaction between microalgae and copepods in aquaculture live-feed systems, and (2) the use of short-chain fatty acid (SCFA)-modified starch particles as Pickering stabilisers. This study investigates the influence of molecular and colloidal factors, including adsorption, viscoelastic film formation, wettability, and digestion-triggered disassembly, on emulsion stability and functionality. In microalgae-copepod systems, cell-wall polysaccharides, membrane glycolipids, phospholipids, proteins, and extracellular polymers provide amphiphilic motifs and steric-electrostatic barriers that function as bioemulsifiers. In SCFA-starch systems, esterification and inclusion complexation modify particle hydrophobicity and contact angle, resulting in recyclable interfacial armour that provides additional nutritional benefits via SCFA release. This study examines the relationships between structure and function, methods for interfacial characterisation, stability during processing and digestion, and sustainability metrics, including circular bioeconomy approaches that enhance the value of algal residues and fermentation-derived short-chain fatty acids (SCFAs). We propose design rules for clean-label, digestion-responsive emulsions suitable for food applications, nutraceutical delivery, and aquaculture feed oils. The integration of these two platforms reveals opportunities for the development of scalable, low-impact biofunctional emulsions.
