Abstract

The importance of conducting this research is based on observations indicating that the implementation of the Kurikulum Merdeka on the theme of local wisdom has been limited to Sabtu Budaya (Cultural Saturday) activities, without further integration into the learning process, particularly in the development of learning tools. This research aims to develop a learning tool based on the CRTT model with a SSI approach that is both valid and practical. The type of research employed is Research and Development (R&D), with a 4D development design limited to the define, design, and develop stages. The development stage is restricted to validation and practicality testing. Data collection techniques included expert validation sheets, student and teacher response questionnaires, and observation sheets for the implementation of learning activities. Data analysis techniques used Aiken's V validity index, Percentage of Agreement, and percentage method. The results of the content and construct validity tests indicate that the learning tool based on the CRTT model with the SSI approach is classified as highly valid, with the assessment agreement among validators being reliable. The results of the practicality test show that student responses had an average of 89.02%, categorized as practical, teacher responses were 92.81%, categorized as practical, and the implementation of learning activities reached 85.71%. These results indicate that the learning tool based on the CRTT model with the SSI approach is both valid and practical for use in the learning process.

Abstract

The size of collagen which was isolated from the skin of snakehead fish (Channa striata) is important in relation to the pharmaceutical applications of collagen, especially in collagen solubility and its dispersion systems for topical applications. In smaller sizes, even reaching nanometer sizes, it is hoped that it will improve the penetration of collagen through the skin when applied. The aims of this study is to obtain collagen microparticulates isolated from the skin of snakehead fish (Channa striata) in a smaller size using the desolvation method with variations in the ratio of collagen and ethanol (w/v) 1:1 and 1:2, stirring time 15, 30, 60 , 120 minutes, and the stirring speed of 3000, 6000, 12000 rpm. The collagen was characterized by its physicochemical properties including particle size, thermal properties, X-ray diffraction patterns, morphology with SEM and infrared spectra. The results of characterization of collagen after treatment with the ratio of the addition of collagen and ethanol 1:2, for 1 hour, and a stirring speed of 12000 rpm showed the smallest particle size was 24.746 μm. Morphological analysis showed random coils indicating the nature of collagen fibrils and no change in functional group analysis. Thermal analysis showed a decrease in the melting point peak from the thermogram results, as well as the intensity of the X-ray diffraction pattern which still shows the characteristics of collagen. The results showed that there was a reduction in the size of the new collagen particles down to the micrometer scale and there was no change in the structure of the collagen triple helix.

Abstract

Karimunjawa National Park (TNK) area is ± 111,625 hectares covering 27 islands located in Jepara Regency, Central Java at the northern tip of Java Island. Karimunjawa became Karimunjawa National Park (TNK) based on the Decree of the Minister of Forestry and Plantation No.78/Kpts-II/1999 because it has high diversity. The complexity of ecosystems in TNK is interesting to study, such as coral reef ecosystems, mangrove forests, lowland tropical rainforests, seagrass meadows, seaweed, and coastal forests. The mangrove forest in Karimunjawa National Park is a unique ecosystem because it consists of many mangrove species. However, data on the diversity of mangrove species on this island has not been widely described. This study aims to reveal mangrove diversity in Karimunjawa National Park as a rescue strategy and explore the potential of mangrove biodiversity. This research is a descriptive study using the cruising method to explore mangrove species diversity. The location of mangrove diversity exploration is mangrove forest in Karimunjawa National Park. The results found 14 families consisting of 38 mangrove species. Among the 38 species, 24 species are true mangroves, while the other 14 species are associated with mangroves.

Abstract

Indonesia's male population is mostly smokers. The chemical content in cigarettes can reduce the quality of spermatogenesis, where spermatogenesis is influenced by the DAZ gene (deleted in Azoospermia). This study aims to analyze sperm quality in light, moderate, and heavy smokers in 3 age groups and analyze the presence of the DAZ gene in heavy smokers. This study used 180 samples divided into three age groups, namely men aged 26-30 years, 31-35 years, and 36-40 years. Each age group recorded the number of cigarettes consumed per day (light, moderate, and heavy smokers) and examined the quality of sperm. While the DAZ gene analysis used 10 samples of heavy male smokers, aged 25-40 years. Sperm quality analysis was based on the WHO laboratory manual for human semen testing, while DAZ gene analysis used the PCR method. Sperm quality data were analyzed using Kruskal-Wallis, while the DAZ gene was analyzed qualitatively descriptively by analyzing electrophoresis photos. The results of this study can be concluded that daily cigarette consumption in the age group affects sperm quality and in heavy smokers, there are 10% who experience deletions in the DAZ gene. Thus cigarettes can reduce spermatozoa quality.
