In the face of increasingly competitive competition in the hospital industry, RSU managers are required to be able to develop strategies, policies or new breakthroughs related to improving the quality of their services, through improving the characteristics of hospital services, which focus on patient needs, so that the risk of errors or discrepancies between service characteristics that are enhanced by what the patient wants can be avoided or minimized. From the results of research conducted there are 21 variables of patient needs from a health service at the Government General Hospital (RSU). Whereas the patient’s research on the service quality of the Government Hospital is 1 variable that has fulfilled the needs of patients, namely that they are satisfied with the quality of hospital services. Variable is the state and completeness of modern medical facilities. Whereas for other variables there are gaps so that they cannot meet patient expectations until the highest quality limit is very satisfied, it is necessary to have a direction of improvement. To obtain the suitability, the technique used to improve the characteristics of the service is the application of the QFD method. The QFD method in this study is in the form of a quality service matrix at the Government General Hospital. From the HOQ matrix, the service quality of the Government Hospital is obtained from the input of the Government Hospital/management that there are priority variables needed to improve their quality, which is generally the patient’s needs related to the recovery of patients, including the knowledge and abilities of doctors, medicines the treatment given in the healing of patients, the service of examination, treatment and care that is fast and precise, guarantee of security and trust in the services provided and the completeness of the readiness and cleanliness of the equipment used. So there are 33 service quality characteristics prioritized for further improvement, with the main priority being patient recovery.

The researches on topological indices are initially related to graphs obtained from biological activities or chemical structures and reactivity. Recently, the research on this topic has evolved on graphs in general and even on graphs obtained from algebraic structures, such as groups, rings or modules. This paper will present various topological index concepts, various graph concepts obtained from a commutative ring and some previous studies that are relevant to those two concepts. Based on the various concepts presented, research topics related to topological indices of a graph associated with a commutative ring can be found and carried out.

Research on the spectra of a graph still attracts the attention of many researchers over the last decades. In addition, research related to graphs obtained from an algebraic structure such as groups and rings is also growing. This paper determines the spectrum of the anti-adjacency and Laplacian matrices of inverse graph of a finite commutative group, namely the addition group of integers modulo n. It can be concluded that all eigenvalues of anti-adjacency and Laplacian matrices of the inverse graph of addition group of integers modulo n are integer

Perbedaan susunan ayat Al-Qur’an dengan urutan diturunkannya Al-Qur’an menarik untuk diteliti. Yaitu Izza Rohman yang mengkaji tentang perbandingan urutan ayat Al-Quran antara muskhaf dan kejadiannya. Tujuan dari penelitian ini untuk mengupas ulang dengan mengkaitkan dengan kajian-kajian lain yang melengkapi kajian dari Izza Rohman. Metode penelitian yang digunakan adalah dengan pendekatan literatur yang menggunakan literatur-literatur yang ada kemudian mengkaitkannya menjadi satu kesatuan. Hasil penelitian menunjukkan bahwa urutan surah dan ayat Al-Quran menjadi inspirasi dan objek kajian yang perbedaan urutannya mempunyai alasan mendasar. Ditemukannya adanya keteraturan dan keserasian dari nomor surah dan ayat dalam Al-Quran. Keteraturan dan keserasian ini menunjukkan kemukjizatan Al-Quran dilihat dari bilangan tartib surah dan ayat-ayatnya. Salah satunya adalah kajian tentang keistimewaan bilangan 7 dan bilangan 19. Dari bilangan tersebut dapat diungkap beberapa rahasia nomor surat dan nomor ayat. Selain itu juga kajian tentang lafadz bismillah yang didalamnya mengandung angka 7 dan 19 juga.   The difference in the arrangement of the verses of the Qur'an with the order in which the Qur'an was revealed is interesting to study. Namely Izza Rohman who studied the comparison of the order of the verses of the Qur'an between the muskhaf and its occurrence. The purpose of this study is to re-explore by linking it with other studies that complement the study of Izza Rohman. The research method used is a literature approach that uses the existing literature and then links it into a single unit. The results showed that the order of the surahs and verses of the Qur'an became the inspiration and object of study whose different sequences had basic reasons. The discovery of the regularity and harmony of the number of surahs and verses in the Al-Quran. This order and harmony shows the miracles of the Al-Quran seen from the number of tartib surahs and verses. One of them is the study of the peculiarities of the numbers 7 and 19. From these numbers, several secrets of letter numbers and verse numbers can be revealed. In addition, there is also a study of the bismillah lafadz which contains the numbers 7 and 19 as well.
