This study aims to determine the effect of Field Work Practice (PKL) and Career Planning on the Job Readiness of grade XII students at SMKN 31 Jakarta. The research employed a quantitative method with a survey approach. The population consisted of all grade XII students of SMKN 31 Jakarta, and a saturated sampling technique was applied so that the entire population became the research sample. Data were collected through questionnaires using a Likert scale and analyzed using validity and reliability tests, classical assumption tests, multiple linear regression, t-tests, F-tests, and the coefficient of determination with the assistance of IBM SPSS. The results indicate that Field Work Practice has a positive and significant effect on Job Readiness, with a t-value of 9.967 and a significance value of 0.000 (<0.05). Career Planning also has a positive and significant effect on Job Readiness, with a t-value of 8.318 and a significance value of 0.000 (<0.05). Simultaneously, Field Work Practice and Career Planning significantly influence Job Readiness, as indicated by an F-value of 88.543 and a significance value of 0.000 (<0.05). The regression equation obtained was Y = -1.782 + 0.638X₁ + 0.450X₂. The coefficient of determination (R²) of 0.571 shows that both variables contribute 57.1% to Job Readiness, while 42.9% is influenced by other factors. The findings suggest that better implementation of PKL and more mature Career Planning are associated with higher levels of student Job Readiness.  

Ethnomathematics studies how mathematics interacts with culture, traditions, and customs of society. With ulos as its identity, this study will investigate one of the Indonesian tribes through its art, namely Ulos art by the Batak tribe of North Sumatra. The form of the Batak ulos variety can be associated with geometric mathematics, so that mathematics can be studied culturally in ethnomathematics studies by integrating the introduction and instillation of culture in the mathematical concepts taught. This research was collected from literature or libraries using a qualitative approach. This study aims to study the concept of geometry in the patterns of North Sumatran ulos cloth from an ethnomathematics perspective. Research shows that science and culture cannot be separated. Batak ulos is not just a traditional cloth; it is also a representation of the hierarchy of cultural values ​​maintained by the Batak people.

This research is based on the development of 21st century learning, where PowerPoint is one of the applications that support learning with attractive designs. This research is a type of R&D development research with the ADDIE model as the development model. The research population was class II students, with a sample of 10 students from SDN Gempolkerep. The data analysis technique used is the Likert Scale. Flat shape material is introduced at the low grade level, and in this product, the material is associated with local culture, especially the culture in Mojokerto, East Java, which is adjacent to this research area. The results showed that the interactive Flat Math media had been tested for its feasibility and declared fit for use. The validation results of media experts get a percentage of 75% which indicates eligibility, while the results of the validation of material experts get a percentage of 86% which indicates very feasible qualifications. Linguist validation also shows decent results with a percentage of 76%. The average questionnaire results from student respondents show a percentage of 80.4% which indicates that this media is very feasible to use. In addition, the teacher's assessment also gave a percentage of 82%. Based on the data analysis, it can be concluded that Flat Math interactive media is appropriate for use in supporting learning in flat shape material.
