The use of goal programming in planning daily menu for the elderly with hypertension
Abstract
This study aims to build a goal programming model to optimize the daily menu planning with hypertension. The objective function of this model is to maximize the nutritional elderly foods according to the Nutritional Adequacy Ratio (RDA), to minimize the food expenses, to maximize the food quantity, and to minimize the consumption of foods containing natrium. Based on the computational experiments conducted by applying this weighted goal programming model, we obtained the optimal solution for the nutritional needs of the elderly with hypertension that is in line with the RDA. Thus, the optimal food menu plans for five days are 12 types of food with an expenditure of Rp. 11,236, - for day 1, 13 types of food with an expenditure of Rp. 9,191, - for day 2, 11 types of food with an expenditure of Rp. 14,036,- for day 3, 12 types of food with an expenditure of Rp. 9,980,- for day 4, and 15 types of food with an expenditure of Rp. 13,098,- for day 5
Power Monitoring and Passenger Classification on Logistics Elevator
The elevator has an important role in assisting transportation and logistics activities in a building. However, if the elevator is not used wisely, then the power consumption will be inefficient. A policy of elevator usage is necessary to ensure the effectiveness of elevator power consumption. Therefore, in this study, elevator power consumption monitoring is proposed. The power consumption behavior can be learned so a suitable policy can be made accordingly. Two elevators in Telkom Campus Surabaya are monitored to understand the daily electrical energy usage. Internet of Things (IoT) based real-time power monitoring system is used to monitor the electrical energy usage of the elevator. A raspberry pi is used to collect the data of electrical usage via a current and power sensor. The data is sent to the cloud, which later is displayed through a dashboard website. The result shows that the elevator usage on weekdays and weekends is different. The peak power on weekdays is obtained from 15.00 to 16.00, meanwhile, on weekends, the peak occurs from 9:00 to 10:00. On weekdays, the total power consumed by the elevator is 51.74kW, while on weekends, it is 11.94kW. Restrictions on the use of lifts are applied to periods when the lift has few passengers and has a short distance. From the results obtained, the total power consumed can decrease by an average of 37%. It is expected that the suggested policies can reduce elevator power consumption and the monthly cost of electrical energy
The implementation of blended learning in the new normal era at vocational school of health
This study aims to describe blended learning in the new normal era in vocational health schools. Vocational education contributes to preparing skilled workforce graduates. Therefore, vocational education must prepare the learning process based on the conditions and needs of students. The research method used was a qualitative approach. A case study was conducted to empirically investigate the phenomenon of the learning process in the new normal era through blended learning. This study collaborated with 96 fourth-semester and 92 sixth-semester students at the Medical Laboratory Technology Study Program in Associate Degree of Health Polytechnic Ministry of Health Manado. The study results showed that during Covid-19, students could not practice directly in the laboratory freely, so it took much work to apply the required course applications in the form of practice. Although out of 188 students, only 110 students often use smartphones in the blended learning process. Students experience the most serious difficulty in understanding and practicing laboratory quality control courses, with a percentage of 38.6%. Therefore, laboratory quality control is considered in terms of student responses to difficult subjects to understand during the online learning process. So that further research is needed to develop a learning system that can increase student learning motivation. Not only up to motivation but students also have to understand how to use technology well

The errors of the first-semester students in solving the angular velocity problem in trigonometry course
Abstract
This qualitative research that used case study approach aimed to describe the errors of the first semester students in solving the angular velocity problem. Seven students of the mathematics education study program at a university in Malang City involved as the research subject. The data collected in this study consisted of the subject\u27s work on the midterm test which contains angular velocity problems and transcripts of interviews with the subject. Data analysis of the subject\u27s work was carried out by classifying based on the types of errors. Meanwhile, the transcript analysis of the interview results was carried out by coding the words that indicated the cause of the subject\u27s error. The results showed that the errors of the first semester students in solving the angular velocity problem consisted of conceptual and principle errors. The conceptual errors were caused by a lack of understanding of angular velocity concept and the factor causing principle errors was the misunderstanding that the linear velocity formula is the same as the angular velocity formula. Therefore, to avoid this error, the learning of angular velocity is suggested to emphasize the understanding of the concept of angular velocity and the difference between the angular and linear velocity formula
