Abstract

This study investigates the use of coal fly ash as a filler in Room Temperature Vulcanization (RTV) silicone rubber to enhance its mechanical properties. Fly ash, which contains silica, has the potential to improve the strength of the polymer. The research aims to optimize the composition of fly ash in RTV silicone rubber composites using the quadratic regression method, focusing on tensile strength and elongation performance. Tests were conducted according to ASTM D 412 standards for tensile strength and elongation. The results showed that the optimal fly ash composition for tensile strength was 38.11%, resulting in a tensile strength of 0.19 and a Mean Absolute Percentage Error (MAPE) of 13.64%. For elongation, the optimal composition was 14.95%, with an elongation value of 192.094 and a MAPE of 24.75%. This study provides valuable insights into how fly ash can be used to enhance the mechanical properties of RTV silicone rubber composites.

Abstract

The LGBT (Lesbian, Gay, Bisexual, and Transgender) phenomenon among adolescents is increasingly a concern in the educational environment. It emerges in adolescents’ social lives, both as part of self-identity and as an issue that raises pros and cons in school. The lack of understanding and empathy towards this issue often gives rise to discriminatory behaviors that negatively impact the psychosocial development of adolescents. This article lifts up the good practice of implementing group tutoring in schools as a strategic approach in building students’ understanding and empathy towards LGBT issues. Through descriptive qualitative methods and a participatory approach, this article highlights how group tutoring is a safe container for discussing, exploring values, as well as fostering inclusive attitudes among students. Results indicate that the implementation of structured and empathetic group tutoring is capable of reducing prejudice as well as forming tolerant attitudes toward diversity of sexual orientation and gender identity. The purpose of this article is to look at how group tutoring functions as an educational and preventive method in building students’ understanding and empathy towards LGBT issues. To achieve this goal, a literature study has been conducted that examines various methods of group tutoring, particularly those based on humanistic and social, in building inclusive attitudes among adolescents. Study results show that group tutoring helps teens understand diversity, become more empathetic, and makes schools safe and welcoming for all students, including LGBT students. This article emphasizes the role of kindergarten teachers in designing group tutoring programs that are sensitive to diversity issues to support adolescents’ social-emotional development.

Abstract

Various problems that arise are caused by the school quality zoning system policy, low student learning motivation, and low student competence. The purpose of this study is to analyse the problems/inhibiting factors of the zoning system. This study uses the sequential mixed methods method, especially the sequential explanatory strategy. Based on the results of the study, it was found that the advantages of the zoning system are cheaper, such as cheaper student transportation costs to school, no discrimination against favourite schools, and encouraging teachers to be more creative in designing learning that is in accordance with student conditions, while the problems and supporters of the implementation of the zoning system in accepting new students. Some implications and recommendations obtained from this study. First, for the central government, considering that the competition for prospective students with the zoning system is getting tighter, the Central Government must adjust the existing provisions by reducing the percentage of the zoning system path and increasing the percentage of the achievement path. Second, the Provincial Government in determining the zone does not only refer to the distance between home and school but also needs to optimize the involvement of community leaders in determining the zone of each school.

Abstract

Ketidakseimbangan merupakan suatu keadaan yang disebabkan salah satu ataupun seluruh fasa pada tarnsformator mengalami perbedaan, terjadi dikarenakan besarnya beban pada tiap fasa berbeda. Hal tersebut mengakibatkan adanya arus yang mengalir pada penghantar netral yang menimbulkan terjadinya rugi arus netral, serta kerugian berupa daya yang hilang dan dapat menyebabkan kerugian secara ekonomi. Pada saat dilakukan pencatatan beban gardu distribusi XY, besarnya nilai beban pada tiap-tiap fasanya berbeda, sehingga menyebabkan terjadinya rugi arus netral sebesar 2,03 kW dengan besarnya daya yang hilang sebesar 240844,2367 kW. Untuk mengatasi hal tersebut, maka perlu dilakukan pemerataan beban dengan memindahkan beban pada fasa yang tinggi ke fasa yang memiliki beban lebih rendah menggunakan atau diistilahkan pecah beban. Hasil yang diperoleh besarnya rugi arus netral turun menjadi 0,003 kW dengan besarnya daya yang hilang sebesar 45793,79 kW. Sedangkan pangaruhnya terhadap keandalan diketahui bahwa ketidakseimbangan beban memberikan pengaruh terhadap besarnya rugi arus netral berdasarkan perhitungan nilai koefisien korelasi yang didapatkan bernilai 0,24543558 meskipun termasuk dalam kategori rendah. Dari hasil kajian tersebut bahwa ketidakseimbangan beban dengan menggunakan metode pecah beban dapat menurunkan nilai arus netral dan besarnya daya yang hilang, yang berimplikasi rugi arus netralnya menjadi lebih rendah. Imbalance is a condition created by variances in one or more of the phases in the transformer, which happens because the magnitude of the load on each phase is different. This causes current to flow in the neutral conductor, resulting in neutral current losses, as well as power losses and economic losses. The magnitude of the load value on each phase varies when the XY distribution substation load is recorded, resulting in a neutral current loss of 2.03 kW and a power loss of 240844.2367 kW. To accomplish this, the load must be equalized by shifting the burden from the high phase to the phase with a lower load, a process known as load breaking. The magnitude of the neutral current loss was reduced to 0.003 kW, resulting in a power loss of 45793.79 kW. While it is known that load imbalance influences the amount of the neutral current loss, based on the calculation of the correlation coefficient value obtained is 0.24543558, despite being in the low category. From the results of the study, the load imbalance using the load rupture method can reduce the value of the neutral current and the amount of power lost, which has implications for lower neutral current losses.

Abstract

The use of electricity has now become a primary need for people who are used for activities as an energy source such as: lights, air conditioners, water pumps, washing machines, TVs, etc. and the longer the need for electrical energy in Indonesia is increasing while power plants are constantly increasing, this forces the government to continue to build power plants to meet the needs of electrical energy in the community. Of course, the construction of this power plant uses very large costs and various obstacles, one of the obstacles is that fuel that used to be a power plant used a lot of oil, now switches to gas and coal to reduce high electricity production costs. The research method that will be carried out is by feeding the generator output back into a rotor drive energy source so that there is a continuous circulation of energy so that the generator output can be charged according to the remaining power capacity fed by the generator. Based on the test results, results were obtained using a 25 Watt DC motor when the input voltage was 12 Volts the power generated on the motor was 13.8 Watts with a motor speed of 768 rpm. Testing on an 800 Watt generator obtained a maximum rpm result of 764 and a vout of 13.8 volts. the highest input voltage (Vin) obtained was 10.06 volts, the output voltage (Vout) was 3.9 volts, and the power produced was 41.34 Watts. The prototype design that was tested produced energy even though the results were still not significant.
