Judul: Studi peran subsektor perikanan dalam pengembangan wilayah di Kota Sibolga
Abstrak: Fisheries subsector is expected to be a strategic sector for future regional development in Sibolga, because this sector based on local resources that can be renewable. The purposes of this study are to: (1) to identify the fisheries subsector development in Sibolga, (2) to analyze the backward and forward linkages of the fisheries subsector economy in Sibolga, (3) to explore the perceptions of stakeholders about fisheries subsector development in Sibolga and (4) to formulate the direction of fisheries subsector development priorities in Sibolga. The data analysis used are descriptive analysis, Hierarcy Analytical Process (AHP), and Input-Output (I-O). The results showed that the fisheries subsector contributes the highest gross regional domestic product up to 22.86% and contributes to the total output up to 17.70%. Fisheries still have a potential to explore 123,63 thousand tons in WPP-572 zones, in addition to the exploitation outside the exclusive economic zone. The aquaculture activities (KJA) still have space 1,276.97 Ha to be used, located in the district of North Sibolga and Sibolga City. Fishieries subsector in total still has small backward and forward linkage. The low linkages fisheries subsector provide a low impact on increasing the output of other sectors directly and indirect linkages to other sectors. The perception of all stakeholders says human resources from fishing activities is a top priority in developing the fisheries subsector, but from analysis human resource aquaculture should be a priority development in fisheries subsector in Sibolga.

Judul: Beberapa aspek pembangunan perikanan laut di kotamadya Sibolga, Propinsi Sumatera Utara
Abstrak: Kotamadya Sibolga merupakan salah satu daerah perikanan di Sumatera Utara dan pusat perdagangan bagi beberapa daerah kabupaten disekitarnya serta perikanan laut merupakan tumpuan utama dalam sub-sektor proses pembangunan ekonomi daerah. Namun, tingkat eksploitasi sumberdaya perikanan pantai sudah cukup tinggi, peranan Kotamadya Sibolga sebagai pusat perdagangan sudah mulai menurun dan tidak lagi merupakan jalur utama lintas Sumatera. Penelitian ini bertujuan untuk: menggambarkan pola usaha perikanan tangkap (unit tangguk dan pancing bagan tancap, pancing ulur dan pukat cincin), usaha perdagangan ikan, pola usaha pengolahan menggambarkan peranan sub-sektor perikanan laut pola ikan, dalam pembangunan ekonomi Kotamadya Sibolga dan menggambar- kan pola pembangunan perikanan laut Kotamadya Sibolga. Penelitian ini mengambil perikanan laut Kotamadya Sibolga sebagai kasus, dimana nelayan pemilik, pedagang dan pengolah ikan, pejabat pemerintah dan pemuka masya- rakat sebagai responden. Pengambilan contoh nelayan pemilik dilakukan secara "stratified random sampling", pengambilan contoh pedagang dan pengolah ikan dilakukan secara "acak sederhana", sedangkan pengambilan contoh pejabat pemerintah dan pemuka masyarakat dilakukan secara "purposive". Pola usaha antar usaha perikanan ditinjau dari beberapa faktor usaha, seperti jumlah buruh, hari kerja upah, bagi hasil, investasi, biaya total, produksi, ni- lai produksi, pendapatan, investasi per pendapatan nilai produksi per investasi, nilai produksi per biaya total (per unit usaha per tahun), jumlah unit alat tang kap, investasi, produksi dan nilai produksi per jenis alat. Faktor usaha antar usaha perikanan di analisis berdasarkan skor. Pola usaha perdagangan dan pengola- han ikan hanya ditinjau dari beberapa faktor pola usaha seperti jumlah buruh, hari kerja, upah, bagi hasil, modal kerja/investasi, biaya total, produksi, nilai produksi, pendapatan, modal kerja/investasi per pendapatan dan nilai produksi per modal kerja/investasi serta nilai produksi per biaya total. Faktor usaha perdaga- ngan dan pengolahan ikan tidak di analisis berdasarkan skor, karena tidak dibandingkan satu sama lain. Peranan sub-sektor perikanan laut dalam pembangunan ekonomi Kotamadya Sibolga digambarkan berdasarkan : besarnya sumbangan sub-sektor perikanan laut..dst

Judul: Rancang Bangun Alat Ukur Kadar Larutan Glukosa Berbasis Film Barium Stronsium Titanat (BST)
Abstrak: Barium strontium titanate (BST) is a photodiode as a ferroelectric material that has been developed in many application such as sensor technology. The purpose of this study is to design a simple measurement tool of glucose with BST thin film as the sensor component and the signal conditioning. The measurement tool test was done by measuring blood glucose levels ranging from 20 to 180 mg/dL, which is the range of glucose levels for person who has lack glucose to the excess glucose. The test results showed that the measurement tool could detect each addition of glucose levels by 1 mg/dL which would reduce the value of the output voltage of 0.0022 V. In addition, the test results showed that the response of the circuit approach to linear, the correlation coefficient (R2) is 0.9155 and 0.8931. The test results also showed good hysteresis as showed by the relatively same graphic plots.
