Abstract

This study aims to develop scientific literacy-based cognitive e-assessments on chemical bonds and describe the validity, teacher responses, and student responses to the developed e-assessment. The research design used in this study was a research and development (R&D) design according to Gall, Borg, & Gall (1996). The instruments used in this study were expert validation questionnaires, teacher response questionnaires, and student response questionnaires. The data obtained from validators, teachers, and students were then analyzed by descriptive statistical analysis method. This scientific literacy-based cognitive e-assessment uses 4 aspects of scientific literacy, namely aspects about the knowledge needed for intelligent participation in science-based social problems, aspects about the ability to think critically about science and dealing with scientific expertise, aspects about understanding science and its applications, and aspects about understanding science and its applications. knowledge of the risks and benefits of science. This e-assessment was created to measure students' scientific literacy. The results of expert validation and teacher responses on aspects of content suitability, construction aspects, and readability aspects indicate a very feasible category. The results of student responses on the construction aspect and the readability aspect showed the criteria were very feasible. Thus, the scientific literacy-based cognitive E-assessment on the chemical bonding material developed can be said to be valid and feasible to use.Keywords: cognitive e-assessment, chemical bonding, scientific literacy.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1320-1327

Abstract

The main problem that is generally faced by textile industry players is related to the large amount of liquid waste produced. Liquid waste from methylene blue dye cannot be discharged directly into the water because it has a high solubility level and is non-biodegradable. Therefore, in this study, treatment of methylene blue dye waste was carried out using an easy-to-apply electrocoagulation method with a high level of efficiency for separating pollutant levels in wastewater. The next step is the decolorization of methylene blue dye waste with a given voltage variation of 20,25, and 30 volts and variations in the time used for 1,3,5,10,15,20,25, and 30 minutes. Based on the results of the study, shows that the greater the electric voltage and the longer the electrocoagulation process is carried out, the higher the decolorization value produced by the methylene blue dye waste. The results of the decolorization obtained were then continued by analyzing the reaction rate which showed a change in the concentration of methylene blue which was directly proportional to the given time. The reaction rate analysis was carried out using a reaction kinetics model, namely first order, second order, and BMG. Based on the values generated from the three reaction kinetics models, the BMG kinetic model is the best reaction kinetics model because it has a high coefficient determination (R2) of 0,999.

Abstract

Abstract This study examines the development of research on the financial sustainability of creative economy micro, small, and medium enterprises (MSMEs), with a focus on the culinary subsector. A Systematic Literature Review (SLR) was conducted using a structured procedure guided by the PRISMA framework to synthesize relevant academic publications. The findings indicate that MSMEs dominate the research focus, particularly in relation to economic resilience and post-crisis recovery. However, studies addressing financial sustainability, financial management practices, and culinary-specific contexts remain limited. The literature is also dominated by quantitative approaches, highlighting the need for more integrative and context-sensitive research to strengthen the long-term financial sustainability of culinary MSMEs.

Abstract

Lemukutan Island is a marine conservation area in Bengkayang Regency, West Kalimantan, with high marine resource potential. Besides supporting tourism activities such as diving and snorkeling, its waters host ecologically important giant clams (Tridacnidae), which function as natural biofilters in reef ecosystems. However, information regarding the biodiversity and population status of giant clams in this area remains limited. This study aimed to assess the density and distribution patterns of giant clams in the waters of Lemukutan Island. Field data were collected in July 2025 at four observation stations representing the eastern and western parts of the island using the belt transect method (50m x 5 m). Data analysis included calculations of density, relative abundance, and distribution patterns using the Morisita Index. A total of 329 individuals belonging to three species were recorded: Tridacna crocea, T. maxima, and T. squamosa. T. crocea was the most dominant species at all stations, with the highest average density (0.231 ind/m²) and relative abundance (14.732%). In contrast, T. squamosa showed the lowest average density (0.067 ind/m²). Station 2 exhibited the highest overall density (0.254 ind/m²) and relative abundance (16.241%) compared to other stations. The distribution pattern of giant clams was predominantly clumped. However, a more uniform distribution of T. crocea and T. maxima was observed at Stations 3 and 4. Variations in density and distribution were closely associated with coral reef availability and water quality conditions. These findings provide baseline data to support sustainable conservation and management of giant clams in Lemukutan Island waters.
