Abstract

This study examines Muhammadiyah's response to Salafism in the context of the shift in authority of the puritanism movement. Muhammadiyah as an organization that carries out Islamic movements by focusing on the tajdid movement, one of which is in the field of religion by purifying Islamic teachings from the influence of superstitious practices, bid'ah, and superstition. In its development, the purification movement was also carried out by other groups, one of which was the Salafi. Automatically the presence of the Salafi movement influenced the position of Muhammadiyah, resulting in a shift in the authority of the puritanism movement. Including the stigma of Muhammadiyah as a Salafi. Based on the literature search, Muhammadiyah is still trying to maintain the purification movement. But still trying to show the difference by emphasizing the renewal movement in understanding religion.

Abstract

The COVID-19 pandemic has had an impact on all fields, including education. During a pandemic like now, learning cannot be done face-to-face but is replaced with online learning. This affects the process of learning Arabic. This study aims to determine how the process of implementing Arabic language learning, the effectiveness of Arabic learning, and describing the obstacles in learning Arabic during the pandemic for students of the Islamic Religious Education Study Program. This research was conducted using qualitative research methods using a phenomenological approach. From the data collected, it shows that 1) The implementation of Arabic learning has been going well by the designed learning plan. In the Arabic language learning objectives, several achievements are divided into four categories, including the learning outcomes of attitudes and values, general skills learning outcomes, specific skills learning outcomes, and knowledge acquisition learning outcomes. The learning media used are google meet, zoom, Schoology, WhatsApp, PowerPoint, or pdf. The learning method used is the method of discussion and information search. The evaluation system uses assignments and a structured exam which is divided into two, namely the mid-semester exam and the end-semester exam. 2) The effectiveness of learning Arabic cannot be separated from the development of methods applied by teaching lecturers. The Group-Based Master Learning (GBML) method is one of the methods used to make it easier for students to learn. 3) two factors become obstacles in the process of learning Arabic. The first is the internal factor, namely, the different educational backgrounds of students and a sense of saturation due to online learning. The two external factors are signal constraints, time differences, and the number of quotas used in the learning process.

Abstract

Background: GRAPPA or Generalized Auto-calibrating Partially Parallel Acquisitions is a parallel acquisition technique which can reduce the scan time in MRI examination. Aims: This study aims to investigate the effect of the R-factor variation of GRAPPA on image anatomical information quality and to determine the optimization value of GRAPPA e-factor to fasten the scan time with acceptable image information quality. Methods: Eight respondents will perform T2 axial Brain MRI examination with various values of GRAPPA R-factor (1 to 7), evaluation was conducted with questionnaire which was given to 3 radiologists to assess the anatomical structure of the lateral ventricle, thalamus, caudate nucleus, lent form nucleus, internal capsule and background area. Data from respondents were then tested with Spearman test and Friedman test. Results: Statistics test showed that there was significant effect of GRAPPA parallel acquisition technique on the anatomical image information quality of T2 axial Brain MRI (p value of 0,001<0,05) and the correlation direction was negative, in which the higher the value of r-factor GRAPPA used, the lower the quality of anatomical image information. Based on the result of mean rank, image with optimal image anatomical information quality was image with GRAPPA R-factor of 1 (mean rank = 6.01), but image anatomical information quality with GRAPPA R-factor of 3 was acceptable with fast scan time (opinion of 75 % of all radiologists). Conclusion: R-factor at GRAPPA parallel acquisition technique could reduce scan time, but the higher the value of r-factor GRAPPA used, the lower the quality of image anatomical information.

Abstract

Abstract: The country of Indonesia is now experiencing business development in the culinary field, so that local restaurants or restaurants compete to rack their brains to provide good and unique services in increasing the interest of their respective customers. Coupled with the increasingly rapid development of globalization, many foreign-style restaurants/restaurants have emerged which are being loved by local people. However, the Indonesian state with a Muslim majority population will certainly be careful in choosing a restaurant, because in Islam there are halal and haram laws that regulate them, so that a restaurant is expected to have a halal certificate from the MUI as the government agency that oversees this, as well as in waroeng steak and shakes. The purpose of this study, how important and its role is to use a halal certificate in the waroeng steak and shake business. This research uses descriptive qualitative method. The type of research used is field research. The data used are primary and secondary data. Data collection techniques used include observation, interviews, and documentation. The results of this study indicate that 1). Halal certificates are very important in the restaurant business, this can be seen from the results of research conducted by researchers on the waroeng steak and shake business. 2). The role of halal certificates in the waroeng steak and shake business in increasing customers is very large.

Abstract

Gas buang mesin diesel merupakan salah satu penyebab terjadinya pemanasan global. Kandungan gas buang ini diantarnya opacity yang berasal dari polutan warna hitam. Unsur karbon dari pembakaran mesin diesel yang ada dalam opacity sangat berbahaya bagi lingkungan. Untuk itu, opacity hasil pembakaran mesin diesel perlu dikendalikan. Metode pengendalian ini diantaranya dengan melakukan pengukuran gas buang menggunakan opacity meter test bench. Harga sangat mahal, tidak praktis dan memerlukan tempat khusus merupakan kelemahan dari opacity meter test bench. Oleh karena itu, Penelitian ini mengusulkan pengembangan opacity meter berdasarkan digital image processing. Kelebihan alat yang dikembangkan memiliki harga cukup terjangkau, praktis dan proses pengolahan dapat dilakukan secara online. Alat ini bekerja berdasarkan perbedaan warna pada gas buang. Kamera menangkap warna gas buang disimpan dalam file jpg. File jpg selanjutnya dikonvert dalam data digital RGB (Red Green Blue). Selain merubah data digital, penelitian ini merancang program yang dapat bekerja dalam komputer. Opacity meter test bench dapat untuk memvalidasi program yang dirancang. Alat yang dikembangkan diuji pada kendaraan micro bus dan pick up. Hasil uji opacity pada kendaraan micro bus memiliki opacity sebesar 19,9% dan nilai RGB (217, 224, 246). Pada saat yang sama, Uji opacity pada kendaraan pick up menghasilkan opacity 20,9% dan nilai RGB (193, 214, 215). Validasi dengan opacity meter test bench terbaca kurang dari 5%. Untuk itu, Desain opacity meter dengan image processing yang telah dibuat sudah dapat beroperasi dan dapat dikembangkan pada penelitian selanjutnya.
