Judul: Analysis on the Satisfaction Level of Work Units in Ministry of Agriculture towards the Planning Bureau Service
Abstrak: Kepuasan layanan oleh Biro Perencanaan Kementerian Pertanian diukur melalui model service quality (servqual) dengan lima dimensi penilaian yaitu tangibles, reliability, responsiveness, assurance, dan emphaty. Analisis dalam penelitian ini adalah gap analysis, Important Performance Analysis (IPA), Customer Satisfaction Index (CSI), dan chi-square test. Berdasarkan penelitian, total rata-rata tingkat kepuasan sebesar 3,166. Nilai rata-rata gap keseluruhan yaitu -0,441, nilai gap negatif bermakna bahwa pelayanan yang diberikan belum semuanya sesuai dengan harapan konsumen. Berdasarkan bagan IPA peubah yang perlu diperbaiki adalah ketepatan waktu penyelesaian permintaan, penyelesaian pemberian solusi, kecepatan proses permintaan layanan, ketepatan perencanaan dan evaluasi, dan regulasi yang dikeluarkan. Nilai CSI diperoleh sebesar 78,65% yang bermakna secara keseluruhan konsumen merasa sangat puas. Berdasarkan uji chi-square, tidak ada hubungan antara intensitas interaksi dengan kepuasan konsumen, kecuali pada subbagian bahan koordinasi., Service satisfaction by the planning bureau of the ministry of Agriculture in Indonesia was measured through service quality (servqual) with five dimensions, namely tangibles, reliability, responsiveness, assurance, and emphaty. This research used several analysis, namely gap analysis, important performance analysis (IPA), customer satisfaction index (CSI), and chi-square test. Based on the results, the total average satisfaction level was 3,166. The overall gap value was -0,441, negative gap value means the services provided are not all in accordance with customer expectations. According to the IPA diagram, variables that need to be improved are the timeliness of request completion, solution completion, speed of request processing, accuracy of planning and evaluation, and regulation issued. The value of CSI was obtained by 78,65% which means the overall customer was very satisfied. Based on the chi-square test, there was no relationship between the intensity of the interaction with customer, meanwhile, the coordination material subsection.

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.
