EVALUASI KEANDALAN BANGUNAN DITINJAU DARI PERSYARATAN KESEHATAN DAN KENYAMANAN RUMAH SUSUN BIDARA CINA

2023-11-03T21:28:14+07:00

This research aims to determine the level of health and comfort based on Minister of Public Works Regulation Number 29 of 2006 concerning Guidelines for Technical Building Requirements for Bidara Cina Flats. The method used is descriptive research using a quantitative approach. The population in this study were families who lived in flats. The sampling technique used a formula developed by Isaac and Michael to obtain 194 samples. The results of this research show that the perception of the residents of the Bidara Cina Flats regarding health, with a percentage of 72.075%, can be said to be that the level of health in the Bidara Cina Flats is Medium. It is shown based on the results of each aspect of health, namely the ventilation system, lighting system, sanitation, and The use of building materials in Block II is better than in Block I. Then the occupants' perception of comfort in the Bidara Cina Flats is still considered moderate, with a percentage of 66.355%. This is shown based on the results of each aspect of comfort, including movement space, air condition, sight (visual), sound (audio), and social environment in Block II are better than in Block I.

ANALISIS KEMAMPUAN PSIKOMOTORIK SISWA TERHADAP MATERI PRODUKTIF DI SMKN 2 BANDA ACEH

2023-11-03T21:27:20+07:00

Capacity can be developed into amazing skills that can boost personal creativity. A person's abilities, skills, or psychomotor abilities are all related. This study aimed to assess the psychomotor proficiency of SMKN 2 Banda Aceh students. P1, P2, and P3 of the psychomotor scale were used in this study to examine imitation, manipulation, and articulation. Interviews were done as part of the qualitative research process. Both in-person and online interviews using the WhatsApp app were done by visiting the informant at school. In the odd semester of 2020–2021, the interviews' findings indicate that students' psychomotor skills in productive material are restricted to P1 or imitation. Each student receives homework assignments from the teacher as part of the learning process. This is due to the COVID-19 epidemic, which outlawed busy activities in classrooms and forced learning to continue online. Lack of action in the lab causes unskilled students, therefore the teacher employs real-world video tutorial media that the students can copy. Teachers find evaluating students' psychomotor skills challenging because they have limited resources and can only evaluate their knowledge abilities.

UJI KINERJA FREEZER MENGGUNAKAN DIMETHYL ETHER SEBAGAI REFRIGERAN PENGGANTI R134a

2023-11-03T21:25:21+07:00

R134a is widely used as a refrigerant in refrigeration systems, but this refrigerant has an impact on increasing global warming. This impact can be reduced by using dimethyl ether as an alternative refrigerant to replace R134a. In this research, the performance of dimethyl ether was tested as a substitute refrigerant for R134a in refrigeration system applications in the form of freezers. Tests were carried out by comparing the performance of the freezer when using refrigerant R134a and using dimethyl ether refrigerant. The use of dimethyl ether in the test was varied based on mass, namely 60 grams, 70 grams and 80 grams, or in percentages as much as 30%, 46.7% and 53.3% of the total mass of R134a. The results of this test indicate that the COP value for freezer performance is higher when using dimethyl ether than when using R134a, the efficiency is higher than refrigerant R134a, and the compressor power is lower than R134a. Testing for variations in the mass of dimethyl ether that approached the condition of R134a was at a mass of 70 grams, so that the amount of refrigerant filled with dimethyl ether as a substitute for R134a was reduced to 46,7% of the amount of R134a.

PENGARUH MEDIA PLANETARY POP-UP TERHADAP PERKEMBANGAN KOGNITIF SISWA SMPN 14 BOGOR

This research aims to explore the boundaries opened by using Planetary Pop-Up media and reveal the extent to which this media can enrich students' cognitive abilities. The focus is to deepen understanding of the solar system and the invaluable sun. The method used is Research and Development (R&D) with the ADDIE development approach which includes the stages of analysis, design, development, implementation, and evaluation. The population of this study included all grade 7 students at SMPN 14 Bogor, and the sample was selected randomly using the Simple Random Sampling (SRS) method to ensure fairness in selection. Data collection was carried out through media trials, interviews, pre-test, and post-test. Data analysis used the T-test technique, focusing on paired t-tests to reveal differences before and after using Planetary Pop-Up media. The results of the analysis show that the use of this media does not provide a significant difference in the average pre-test and post-test scores. It is hoped that these findings can significantly contribute to the development of effective learning media, especially in improving students' cognitive abilities. Apart from that, it is hoped that this research can also be a reference for other researchers interested in conducting similar research using a Piagetian theory-based approach. This discovery is a step towards miracles in the world of education, and it is hoped that it will inspire other daredevils to undertake similar adventures. In all the uniqueness and light found, the hope is that these findings will become a guide that guides knowledge seekers to the right path, creating untold miracles in the world of education.
