Project-based learning trajectory on the definition of the set topic
Abstract
This research aimed to describe the project-based learning trajectory passed through by students to understand the set definition. This design research used Gravemeijer and Cobb model with stages: (1) preparing for the experiment that includes developing hypothetical learning trajectory (HLT); (2) design of experiments which includes learning practices implementation based on the developed HLT; and (3) retrospective analysis, which was to compare HLT with learning practices. The development of HLT into a learning trajectory was obtained through a series of activities carried out by collecting data through documentation, observation, and interviews with the teacher and students to clarify and confirm the learning trajectory. The results indicated that project-based learning could facilitate students to understand the definition of set. The learning trajectory was obtained through a series of activities with four levels of modeling. The situational level was in the form of a survey activity aimed to collect objects in the school area. At the referential level, the terms common features , definable , additional objects , and agreement emerged through discussion. At the generalization level, students wrote the set in a more general form. Lastly, at the formal level, the understanding that students get from each activity was a provision to construct a concept about set definition
Projection of the number of students and their acceptance at various educational levels until 2025
No full textThe 1945 Constitution states that education is a right for every citizen. Education is a conscious and planned effort to realize the atmosphere of learning and the learning process so that students can develop their potential. Education in Indonesia aims to educate the nation\u27s life. Indonesia\u27s education system in its development continues to make changes. The zoning policy in education is one form of positive response from the government to equalize education in each region. The zoning policy requires each student to go to school the closest distance from their residence. Schools provide about 90% of the student capacity measured by distance. The zoning policy in its development still leaves various problems. A common problem is the unavailability of educational facilities in a sub-district area so that some students have the potential to not go to school. Bekasi City is a metropolitan city that serves as a buffer for the capital city. In its development, Bekasi City has the potential to experience problems of inequality in the number of students and absorption in schools. This study aims to project the number of students and their absorption at various levels of education in Bekasi until 2025
Millennial generation and family literacy within the dissemination of hoax in Whatsapp group
No full textThe millennial generation emerges in the era of advanced technology. The characters of the generation tend to have advanced knowledge of both technology and information. This convenience, spreading information easily, causes difficulty identifying whether or not the news is factual. Media literacy is necessary for millennials considering this generation is familiar with modern technology. Data are collected through observations and in-depth interviews. The analysis results that spreading Hoax via group chat is capable of anyone, including close and trusted family members. To prevent the act of disseminating Hoax in family and sibling, thus, a family member has an important role in reminding each other of the relevance of media literacy. This study concludes that knowledge and mastery of technology and the management of information from millennials are essential. Therefore the spreading Hoax is diminished. Literacy from generation to response disseminating Hoax in WhatsApp group provides knowledge to group members, especially parent, to be not gullible and easily provoked to single information. The opportunity of disseminating Hoax through a family group in WhatsApp is higher because of the mutual trust among family members and shared the information without clarifying it

No full textThis study aims at describing the work ethics profile of Vocational College Students in Indonesia. Work ethics is an important indicator of human resources quality, and also an element of employability skills, that must be owned by students of Vocational College as working-age population. There are four main dimensions in work ethics: commitment, integrity, professional attitudes, and hard work. It is descriptive research on self-evaluation survey. It uses a Likert scale with five response options, ranging from 1 (never) to 5 (always). The respondents were determined using cluster sampling and convenience sampling. They are from four vocational colleges based on the three regions in Indonesia: College A (representing Western Indonesia colleges), College B and C (from Middle Indonesia), and College D (in Eastern Indonesia). This geographical perspective is used to get a profile of Vocational College students\u27 work ethics regionally and nationally. The study concludes that there is no major difference among the self-evaluation results of work ethics in Western Indonesia, Middle Indonesia, and Eastern Indonesia (the mean scores of the four dimensions in four colleges range from 3.89 to 4.54). The study concludes that integrity is in the highest rank among other dimensions. The one that takes place in the second position is commitment, except the one in College C. It is consecutively followed by being professional (except College C since its being professional is in the second place). The last is hard work. This profile signals positive support towards the demographic dividend for the development of the country

The effect of cold water immersion on lactate, muscle soreness, flexibility and stress level post-sub-maximal physical exercises
Abstract
Strength is one of the main components of bio-motor affecting the development of other physical components. Strength training improves strength and neuromuscular coordination, muscle hypertrophy, contrary causes physical stressor, muscle inflammation, produce muscular disease, increases lactate levels, interferes body metabolism, thus decreases performance. Appropriate recovery methods can prevent over-training, musculoskeletal injuries, stress levels. The study examines the effect of cold water immersion 5°C (CWI5°C) on blood lactate, muscle soreness, flexibility, and stress level after high-intensity resistance training. The study design was pre- and Post-test using a cross-sectional approach with the control group. It gave selected 15 samples treated with CWI5°C for 15 minutes directly after high-intensity resistance training, while control samples with static stretching for 15 minutes. The prerequisite test uses Shapiro-Wilk, while the bivariate analysis uses paired sample T-test and independent sample T-test. The prerequisite test uses Shapiro-Wilk, while the bivariate analysis uses paired sample T-test and independent sample T-test. The results showed there were significant differences between the two groups (p=0.001). The CWI-5 C method recover lactate levels faster (p = 0.001), reduces muscle pain (p=0.003), decrease stress (p=0.002), while SS increase muscle flexibility (p=0.001). We can conclude that 15°C cold water immersion for 15 minutes accelerates recovery, reduce muscle inflammation and stress level, while static stretching increases flexibility after high-intensity resistance training
