Abstract

This research is an exploratory study conducted in Batang Regency. The research samples, namely bitter mustard (Brassica juncea L.) and petsai (Brassica pekinensia L.) leaves, were collected in December 2022. The selection of research samples is based on the level of production and availability. The data analysis method used in the research is descriptive quantitative analysis. The results showed that bitter mustard (Brassica juncea L.) and petsai mustard (Brassica pekinensia L.) have the same epidermal characteristics, namely irregularly shaped epidermal cells with notched cell wall edges and elongated polygonal cells with flat cell wall edges. The epidermal derivatives found are stomata and trichomes. The stomata of the study sample have anisocytic type, closed slit condition, but have different sizes (length and width), index and density. Trichomes have a simple needle-like hair type on the edge of the leaf, but have different sizes (length and width). The differences in the research samples can be observed quantitatively.

Abstract

This study aims to analyze the influence of Islamic law on the development of sharia economics in Indonesia. By examining key sectors such as sharia banking, halal industry, and zakat distribution, this study shows that the application of Islamic legal principles, such as the prohibition of usury, transparency in transactions, and zakat management, has contributed significantly to the growth of the sharia economic sector. The results of the study show a significant increase in total assets of sharia banking, exports of halal products, and zakat management from year to year. Although this sector continues to grow, challenges in the broader integration of Islamic principles and public understanding of sharia economics still exist. Therefore, more in-depth policies and increased public understanding are needed to strengthen the sharia economic sector in Indonesia.

Abstract

This study sought to examine students' perceptions of oral corrective feedback in speaking activities. Instructors used vocal corrective criticism in the classroom, particularly during speaking sessions. Offering vocal comments in the classroom facilitated students' proficient and accurate use of English. The study methodology used a quantitative descriptive approach, with data processed using SPSS version 23 and Microsoft Excel. Data was gathered via the distribution of a questionnaire to examine students' perceptions. Questionnaires were administered to 31 students in the fourth semester of the English Education Department as the study sample. The results indicated that the students achieved a score of 76% after data analysis using SPSS 23, reflecting a good view of oral corrective feedback in the speaking lesson. Another investigation revealed that the students agreed to offer oral corrective criticism during the speaking lesson
