Abstract

The transition of the process of teaching and learning activities from face-to-face learning systems to online learning systems certainly provides significant changes. Online learning requires students to be more active in learning activities because teachers cannot monitor their learning process directly. This study aims to determine teacher and student perceptions, self-efficacy, concept mastery, and the interrelation between self-efficacy and conceptual mastery students of class X MIPA in online learning. The design used is descriptive quantitative with a correlational approach. The research sample consisted of 3 biology teachers and 118 students of class X MIPA SMA Negeri 1 Seputih Surabaya which were sampled from the population using total sampling technique. The research was carried out in June of the even semester of 2021. Quantitative data in the form of mastery of class X students' concepts of environmental change were obtained using questions, while qualitative data in the form of teacher perceptions, student perceptions, and student self-efficacy used a questionnaire in the form of google form. Data on perception, self-efficacy and concept mastery were analyzed descriptively, while the correlation between self-efficacy and concept mastery was analyzed inferentially with Product Moment. The results showed that the teacher's perception was categorized as good (67.28%). Students' perceptions are categorized as good (69.71%). Self-efficacy of students in the high category (67.87%). Mastery of concepts in the high category (39%). There is a positive relationship between self-efficacy and mastery concept of class X MIPA SMA Negeri 1 Seputih Surabaya with a low degree of relationship. DOI: http://dx.doi.org/10.23960/jbt.v11.i1.27394

Abstract

Tempoyak is a traditional fermented food of the Dayak ethnic group in Central Kalimantan. The production of tempoyak remains highly traditional and lacks innovation. Research on tempoyak is still limited, resulting in a lack of documentation of this food as part of Indonesia’s local wisdom and cultural heritage. Therefore, exploring preferences and the appeal of tempoyak’s organoleptic qualities among the millennial generation is essential. This study employed a one-shot case study design. The variables examined include the diversity of microflora in tempoyak and its effect on organoleptic quality and the level of preference among millennials. Isolate identification was conducted using API-50CHL, biochemical tests, and physiological tests. Organoleptic quality was assessed using a hedonic scale. A total of 120 panelists participated in the study, consisting of individuals from Dayak, Madurese, Javanese, and Banjar ethnic groups. Data were analyzed using one-way ANOVA. The study identified 15 microflora isolates in tempoyak that influence its taste and organoleptic properties, including 8 lactic acid bacteria isolates: Pediococcus acidilactici, Lactobacillus curvatus, Leuconostoc mesenteroides, Lactobacillus plantarum, Streptococcus thermophilus, Lactobacillus pentosus, Enterococcus faecium, and Weissella paramesenteroides; 1 non-lactic acid bacterium isolate (Micrococcus varians); 2 yeast isolates (Saccharomyces cerevisiae and Kluyveromyces marxianus); and 4 mold isolates, including Rhizopus, Monilia sitophila, and Mucor roxii. All identified microflora could produce lactic acid, except Aspergillus repens. Statistical analysis showed a significant effect on all sub-variables of organoleptic quality—color, taste, aroma, and texture of Tempoyak. These findings suggest a preference for the color and texture, and a liking for the taste and aroma of Tempoyak. The study indicates potential for Tempoyak to be further developed in a more innovative and contemporary manner, making it more appealing to the millennial generation.Keywords: tempoyak, organoleptic, microflora, Dayak
