Abstract

Curriculum management quality is a fundamental determinant of educational effectiveness in vocational high schools (SMK). This study assesses curriculum management quality across four dimensions: curriculum planning (D1), curriculum organizing (D2), curriculum implementation (D3), and curriculum evaluation (D4), from the perspectives of school administrators and teachers. A quantitative survey design was employed involving 145 respondents selected through proportionate stratified random sampling across five SMK in West Sumatra, Indonesia. Data were collected using a validated questionnaire (44 items; Cronbach's alpha = 0.91) and analyzed using descriptive statistics and one-way ANOVA. Results indicate that overall curriculum management quality achieved a mean score of 3.69 out of 5.00 (Good category). Curriculum Planning (D1) achieved the highest mean (M = 3.82), while Curriculum Evaluation (D4) was the most critical dimension (M = 3.58). Significant differences in perceptions were found across respondent positions (F = 4.83, p = 0.003). This study contributes an integrated four-dimension quantitative framework for assessing curriculum management quality in SMK, providing empirical evidence that evaluation functions represent the weakest link in the curriculum management cycle and that multi-stakeholder data collection is essential for accurate institutional quality monitoring.

Abstract

A stable room temperature is essential for comfort. This study tests the performance of split wall air conditioners with R-22 refrigerant and evaluates how to improve their efficiency through the influence of cooling air temperature. The experiment was carried out by varying the air temperature and cooling load using a heater. Data is taken every 15 minutes for 2 hours using a digital thermometer. The results showed that the maximum coefficient of performance (COP) value reached 8 indoors and 7.2 outdoors. Meanwhile, the maximum energy efficiency ratio (EER) value was recorded at 4.2 indoors and 3.7 outdoors. The stability of COP and EER values indicates that the Split Air Conditioner can operate efficiently despite variations in air temperature and cooling load. Cooler cooling air proved to be crucial in improving system efficiency. Conversely, higher refrigerant loads tend to decrease efficiency. However, this drop can be minimized by keeping the cooling air temperature low. The selection of the appropriate refrigerant, such as R-22, also plays an important role in supporting optimal performance. The combination of cooler cooling air and the right refrigerant allows the split air conditioner to operate with high efficiency. This research provides an important basis for the development of energy-efficient and efficient cooling systems. Optimizing the temperature of the cooling air is one of the main keys in improving the efficiency of the cooling system. With the right approach, split air conditioners can be used more effectively to create thermal comfort while saving energy.

Abstract

Study towards the recycling of PET waste has arisen in the last decades. One of the most widely used methods was the mechanical recycling process due to its simplicity and low cost of production. In this research, PET waste obtained from the disposable water gallon containers was used to produce recycled PET fibers for textile applications. The PET fibers were prepared using the extrusion technique by varying the processing temperatures, i.e., 200, 210, 220, 230, and 240°C. The diameter, FTIR analysis, XRD analysis, and mechanical properties of the PET fibers at various processing temperatures were studied. The results showed that the optimum processing temperature for preparing recycled PET fibers was 210°C with a diameter of 0.23 mm, a degree of crystallinity of 8.9%, a tensile strength of 70.4 MPa, and an elongation at break of 83.6%. In conclusion, PET waste shows a promising application to be processed as recycled PET fibers for textile applications.

Abstract

The low saving culture in Indonesia, where the saving ratio to GDP is only 34.8 percent compared to neighboring countries, is the background for the urgency of financial education from an early age. Unlike conventional socialization which is only based on material presentation, this research offers novelty through an integrative approach to utilizing used bottle waste as a creative piggy bank medium. This study aims to shape saving behavior and financial management understanding in students of SDN 13 Ulakan Tapakis, Padang Pariaman Regency. The method used is descriptive qualitative with data collection techniques through participatory observation, in-depth interviews, and documentation. Research findings show that the use of used bottle media significantly increases visual engagement and students' interest in setting aside pocket money. In addition, this activity was able to shift the consumptive behavior of students who were previously exposed to the negative impacts of social media into frugal behavior with the ability to distinguish between needs and wants. The integration of this creative media proved effective in instilling financial independence and preventing the risk of dependence on loans in the future.
