As a public service, it is required to provide excellent service to animal owners. Puskeswan serves as the frontline of the National Animal Health System (Siskeswanas) according to the Minister of Agriculture Regulation No. 64 of 2007, with functions including animal health promotion, veterinary services, epidemiology implementation, veterinary information implementation, emergency preparedness for outbreaks, and veterinary service provision. This research focuses on assessing respondent satisfaction based on the technical services provided by Puskeswa. The satisfaction of animal owners is a crucial factor that determines the success of the service provided. The issue addressed in this research is the increase in the animal population, which is not accompanied by sufficient facilities and human resources in Puskeswan. As a result, animal owners complain about the lack of services, as well as the available facilities and infrastructure in Puskeswan. This study aims is to analyze the level of satisfaction and expectations of the respondents, as well as the managerial implications for improving the attributes in the service dimensions of three Puskeswan in West Java Province. The measurement of respondent satisfaction in this study utilizes the Servqual method, which consists of five dimensions: tangibles, empathy, responsibility, responsiveness, and assurance. The research method employed in this study utilizes gap analysis based on the concepts of Service Quality (Servqual), Customer Satisfaction Index (IKM), Importance Performance Analysis (IPA), and Structural Equation Modeling (SEM). The respondents are animal owners who have owned and cared for animals for more than one year and have utilized the facilities of Puskeswan in three Puskeswan in West Java Province. The sampling technique used is purposive sampling, with a total of 180 respondents. The research results for IKM measurement indicate that the quality of 3 Puskeswan services in West Java Province falls into the good category, based on the average values of the dimensions with an IKM score of 80.16. Overall, the gap value in this study is 0.21, indicating that 3 Puskeswan in West Java Province needs to improve its services. The highest gap value is found in the tangible dimension, followed by reliability, responsiveness, empathy, and assurance. Some elements that need to be prioritized include the availability of Puskeswan facilities such as buildings, equipment, and medications. However, overall, the respondent express satisfaction with the services provided by 3 Puskeswan in West Java Province, as indicated by an IKP value of 80% in the IPA method, which falls within the range of satisfied customers or Good category

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
