Judul: Kondisi dan potensi pengembangan kepelabuhanan perikanan di Kabupaten Subang
Abstrak: The condition of fishing port facilities related to its number availability and the facilities management had an effect on the outcome. This research aims to analyze the condition of facilities and activities, to know the production of fishing catch and supply trip, and to determine fishing port that potentially to develop. This research used literature study method, descriptive analysis, group, and scoring technique to analyze data. Pursuant to research result known that the condition of fishing port facility in district Subang was far from proper. So that required some effort to make the facilities proper. Gas station, water tank, and ice factory were the facilities that need to repairing, maintenance and improvement in PPP Muara Ciasem, PPP Blanakan, PPI Patimban, and PPI Mayangan. The condition of landing activity, auction, and fish processing was good at district Subang fishing port nor the supply trip such as water, ice and fuel. Pursuant to the result of scoring technique showed that PPP Blanakan get 117 points. It means that PPP Blanakan get the first priority to develop and then PPI Mayangan was the second place with 72,7 points and the last place was PPI Patimban with 71,7 points.

Abstrak: Pelabuhan Perikanan Pantai Muara Ciasem merupakan salah satu ekonomi perikanan yang terdapat di Kabupaten Subang, selain PPP Blanakan. Pelabuhan ini memiliki prospek cukup baik karena memiliki beberpa kelebihan antara lain kebutuhan ikan di sana yang relatif lebih besar dari pada pengkalan pendaratan ikan lain di sekitarnya, keamanan yang terjamin pada saat proses pembongkaran ikan dan pelayanan jasa kepelabuhanan yang baik dari pihak pelabuhan KUD.

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.
