The decision-making empirical model in vocational high school
No full textThe objectives of this research is to know the pattern of causal relationships inter-variables on the decision-making empirical model in Vocational High School (SMK). The decision-making empirical model in Vocational High School, consisting of variables: (a) the adequacy of Information and Communication Technology (ICT), (b) the benefits of using information systems, (c) the ethics in decision making, (d) the contribution of school and social environments, (e) the intentions of behaviour, and (f) the patterns of decision-making. Relation between variables was tested statistically using path analysis. The results of the research are as follows. The varian explained by each variable is mathematically formulated in: ZY = 0.134 A + 0.141 B + 0.102 C + 0.486 D + 0.193 E. The most dominant effect for direct effect is D to E has ÏDE = 0,47 and the correlation coefficient = 0,709
Entrepreneurial character education through the school culture in the vocational high schools
No full textThe study was to describe the implementation of the entrepreneurial character education through the school culture in the vocational high schools (VHSs).The method that the researcher made use in the study was the qualitative one.

The influence of aerobic gymnastic and yoga on the waist-to-hip ratio and the depression level among pre-menopause women
Abstract
The study aims at: (1) identifying how effective aerobic and yoga exercise is in decreasing the waist-to-hip ratio (WHR) and the depression level among the pre-menopause women; and (2) identifying which exercise is more effective, between the aerobic exercise and the yoga exercise, in decreasing the waist-to-hip ratio (WHR) and depression level among the pre-menopause women. The study itself was a true-experimental design with pre-test and post-test control group design. Then, the subjects in the study were the women who entered their pre-menopause age, starting from 40 years old. The samples for the study were gathered by means of probability sampling technique with simple random sampling technique and the total respondents in the study were 60 people. Next, the data for the study were gathered through RLPP formula with measurement tape for the assessment of waist-to-hip ratio and the administration of DASS scale measurement test for the assessment of depression level. The data that had been gathered were analysed using the t-paired sample test and the ANOVA test. The results of the study show that: (1) the aerobic exercise is not effective in decreasing the waist-to-hip ratio and the depression level among the pre-menopause women (p \u3e 0.05) while the yoga exercise is not effective in decreasing the waist-to-hip ration but is effective for decreasing the depression level among the pre-menopause women (p \u3c 0.005); and (2) there is not any kind of most effective exercise in decreasing the waist-to-hip ratio among the pre-menopause women. However, yoga can be the most effective exercise in decreasing the depression level among the pre-menopause women

Implementation of 48V/350W BLDC Motor Speed Control With PID Method Using Microcontroller-Based Sensorless Techniques
No full textA brushless direct current (BLDC) motor is widely used in automotive and industrial applications due to its low noise and high performance. However, traditional BLDC motor control relies on Hall-effect sensors, which increase costs, enlarge motor dimensions, and risk errors from sensor failures. This research focuses on implementing a sensorless control system for a 350W, 48V BLDC motor. The goal is to achieve stable operation at a set speed of 250 rpm, with a steady-state error ≤3%, under varying loads from 0 Nm to 2.7 Nm. Using the Ziegler-Nichols PID tuning method, the study was conducted in the Electrical Machinery Laboratory at Bandung State Polytechnic. The results show that the sensorless control system effectively maintains setpoint speeds of 90 rpm, 120 rpm, 200 rpm, and 250 rpm. At 250 rpm, the system achieved an average steady-state error of 2.44% using PID parameters Kp = 3.13, Ki = 8.69, and Kd = 0.25. The motor’s output power ranged from 136.88W at minimum load to 297.92W at maximum load, demonstrating improved efficiency and system performance
