Abstract

This research is aim to analyze the effect of quench at difference medium on the hardness and the impact of HQ 705 steel which is as similar as AISI 4340 with 0.38 – 0.43% C; 1.82% Ni; 0.5% - 0.8% Cr and 0,25% Mo. HQ 705 steel is heated to austenite temperature of 8500 C and hold as long as 15 minutes and cooled at the difference mediums, which is water, ice and oil. After that, the steels being tempered at temperature of 5500 C and hold as long as 30 minutes, and then again cooled. Finally, the specimens are tested to find hardness, toughness and microstructure. Through this research, we find the increase of hardness, from 33.4 HRC at no treatment to 56 HRC at cooling in water, 40.3 HRC at cooling in oil.

Abstract

Penelitian ini bertujuan untuk meneliti pengaruh perendaman media Asam klorida konsentrasi 3% terhadap kekerasan Alumunium dan Baja karbon. Bahan yang digunakan dalam penelitian ini adalah baja karbon rendah AISI 1018, aluminium 6061, asam klorida (HCl) 3 %, air. Uji kekerasan menggunakan Mesin Rockwell (HRC type C). Hasil uji kekerasan menunjukan baja karbon rendah lebih keras dibandingkan alumunium. Sebab kedua spesimen memiliki perbedaan struktur mikro dan kepadatannya. Dan juga hasil diatas menunjukan bahwa benda uji yang telah direndam dilarutan HCl tingkat kekerasannya berkurang sebab telah terjadi proses korosi dan pelunakan struktur mikronya.

Abstract

Human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) remain significant global health challenges addressed by countries worldwide. The advent of antiretroviral therapy (ARV) has significantly reduced morbidity and mortality of people living with HIV (PLHIV), transforming HIV/AIDS from a fatal disease to a manageable chronic disease. However, the increasing number of elderly individuals with HIV who experience early frailty syndrome presents new challenges and potential for diminished quality of life. The aim of this study was to assess the quality of life and to identify its significant predictors in PLHIV patients who have received ARV therapy in Banda Aceh, a Muslim-majority region in Indonesia. A cross-sectional study was conducted on all PLHIV who received ARV therapy at the voluntary counseling and testing (VCT) polyclinic at Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia between January and February 2023. The WHOQOL-HIV BREF instrument, a multi-dimensional tool developed by the World Health Organization (WHO), was used to assess the quality of life of the PLHIV, and potential predictors were assessed. The Chi-squared test was used to determine the predictors associated with the quality of patient’s lives. Our data indicated that the majority of PLHIV were male (88%), 26–35 years old (78%), employed (92%), and unmarried (54%). Poor quality of life was dominant for the physical health (100%) and social relationships (76%) domains. In contrast, good quality of life was observed in aspects of independence, psychology, and spirituality, all reporting 100% results. Significant associations were found between married status (p=0.004) and medication adherence (p<0.001) with higher quality of life among PLHIV. In conclusion, married PLHIVs that received support from their partners regarding adherence to therapy exhibited a better quality of life. These results underscore the significance of sustained support systems and adherence strategies to enhance PLHIV's quality of life.

Abstract

The variety of biodiversity that grows in Indonesia makes this country the second megacenter in the world after Brazil. More than 30,000 plant species grow and 2,500 of them are medicinal plants one of them is arrowroot (Maranta arundinacea) as well as natural sources of animal wealth such as Dumbo catfish (Powder Clarias gariepinus) which is a source of protein that is needed by the body. Several researchers have also investigated the active compounds contained in the two ingredients, but differences in the environment and the maintenance process significantly affect the chemical content. This research focused on the initial phytochemical test and chemical composition of Maranta arundinacea extract and Clarias gariepinus powder extracted with 40% ethanol by maceration and hydrolysis techniques

Abstract

The author observes that the use of belt grinding is still rare in the writer's own environment, both in the fields of education and small industries, because there are still many people who are fixated on ordinary grinders, and think that ordinary grinders are better in all work. The development of belt grinders has changed people's perspectives through the development that the authors have done, with increasing belt grinding functions through development which will certainly make belt grinders even more useful. This belt burrs are made and developed through pre-existing belt grinding shapes. The result of this development is a belt grinder which has a function more than the belt grinder which is already before. This belt burrs has three types of work functions, namely vertical, horizontal, and cutter, and also features speed control. With the development that the author does, of course, it will change people's perspectives because belt grinding has a function that is better than before and can better help the work of a grinding process.

Abstract

Interaksi teman sebaya memiliki peran penting dalam meningkatkan hasil belajar, terutama dalam konteks masyarakat adat seperti Suku Anak Dalam (SAD) yang bermukim di Bukit Dua Belas, Kecamatan Air Hitam, Kabupaten Sarolangun. Pendidikan Agama Islam (PAI) bagi komunitas ini menghadapi berbagai tantangan, termasuk keterbatasan akses pendidikan, minimnya tenaga pendidik, serta rendahnya keterlibatan orang tua dalam proses pembelajaran. Penelitian ini bertujuan untuk menganalisis bagaimana interaksi teman sebaya berkontribusi terhadap peningkatan hasil belajar PAI di kalangan siswa SAD. Metode penelitian yang digunakan adalah pendekatan kualitatif dengan teknik wawancara, observasi, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa interaksi teman sebaya membantu meningkatkan motivasi belajar, memperkuat pemahaman materi, serta membangun rasa percaya diri dalam memahami nilai-nilai Islam. Oleh karena itu, diperlukan strategi pendidikan yang lebih inklusif dan berbasis komunitas untuk memaksimalkan peran interaksi teman sebaya dalam mendukung pembelajaran PAI bagi masyarakat SAD.
