Abstrak: In Nizam Zachman Ocean Fishing Port (PPS Nizam Zachman), currently consist of 10 institutions. Even though the regulation by minister of agriculture had been published on the relationship between technical executor unit (UPT) and government institution who has the activities in fishing port, mean while inharmonic environment among the institutions still occurred and tend to increase. The main constraint among them predicted respectively as follow 1) the similarity on duty and function between UPT and state owned company (Perum), 2) no specific regulation that Perum and other institution activities have to under UPT coordination, 3) realization of fishery harbor has not yet been fully functioning, and 4) weakness coordination and supporting related institution. The objectives of the study are 1) to assess institutional of PPS Nizam Zachman, 2) to assess the influence of effectively and efficiency of PPS Nizam Zachman management, 3) to compile the capacity building strategy of PPS Nizam Zachman. SWOT analysis and Analytic Hierarchy Process (PHA) was conducted on this study to compile alternate strategy and implemented strategy for capacity building of PPS Nizam Zachman. Based on functional identification and institution authority in PPS Nizam Zachman, there were overlapping, contradiction functional and authority among the institution. The appropriate strategies to improve the capacity building in PPS Nizam Zachman are 1) reform the management in the port, 2) improvement port infrastructure and facilities, and 3) improvement port services. To improve the capacity building in PPS Nizam Zachman, advised to 1) improve port function from infrastructure provider being multi function provider, 2) improve entrepreneurship of fish port manager, and 3) improve of information activities access and port facilities.

Judul: Strategi Pemanfaatan Fasilitas Kolam Pelabuhan Perikanan Samudera Nizam Zachman, Jakarta
Abstrak: Tingkat aktivitas pemanfaatan kolam Pelabuhan Perikanan Nizam Zachman sangat tinggi. Kegiatan bongkar muat dilakukan di kolam yang sama. Luas kolam pelabuhan yang tersedia 40 Ha, jumlah armada kapal yang berlabuh di kolam pelabuhan saat ini sudah mengalami over capacity menyebabkan terhambatnya alur pelayaran dan terjadinya antrian kapal di Pelabuhan Nizam Zachman. Penelitian bertujuan mengidentifikasi model antrian kapal, mengukur tingkat pemanfaatan fasilitas kolam dan merumuskan strategi dalam pemanfaatan fasilitas kolam pelabuhan PPS Nizam Zachman. Pengumpulan data dilakukan melalui wawancara dengan pihak pelabuhan dan nahkoda kapal menggunakan metode accidental sampling. Analisis yang digunakan adalah deskriptif untuk mengetahui keragaman pola antrian kapal, analisis pemanfaatan fasilitas untuk mengetahui berapakah kapasitas seharusnya dermaga dan kolam pelabuhan dan matriks Strenghts, Weakness, Opportunities, Threats (SWOT). Hasil penelitian didapatkan bahwa pola antrian yang diterapakan di PPS Nizam Zachman yaitu jalur ganda-fase pelayanan tunggal. Pemanfaatan luas kolam pelabuhan sudah melampui kapasitas dengan persentase pemanfaatan sebesar 103%. Strategi yang dapat dipertimbangkan dalam pemanfaatan fasilitas kolam PPS Nizam Zachman yaitu penambahan personil syahbandar untuk mengatur kapal di PPS Nizam Zachman, menerapkan PP No 11 tahun 2023 Pasal 1 agar terciptanya distribusi yang merata dari hasil tangkapan dan jumlah kapal yang masuk ke pelabuhan dan melakukan pengerukan pada perairan kolam secara berkala untuk memudahkan kapal melakukan aktivitas di pelabuhan., The level of activity in utilizing the ponds of the Nizam Zachman Fishing Port is very high. Loading and unloading activities are carried out in the same pool. The available port pool area is 40 hectares, the number of ships anchored at the port pool is currently experiencing over capacity causing delays in shipping lanes and the occurrence of queues of ships at Nizam Zachman Port. The aims of the study were to identify ship queuing models, measure the level of pool facility utilization and formulate a strategy for utilizing the PPS Nizam Zachman harbor pool facilities. Data collection was carried out through interviews with port officials and ship captains using the accidental sampling method. Analysis used for this research was descriptive analysis to know fish loading pattern, utilization of the facilities activity to know the capacity of unloading dock and pool port and the Strengths, Weakness, Opportunities, Threats (SWOT) matrix. The results of analysis shows that the queue system implemented in PPS Nizam Zachman was multi channel-single phase queue sytem. Facility utilization of pool port area exceed capacity with utilization percentage 103%. The strategy that can be considered in utilizing the PPS Nizam Zachman pool facility is adding harbor syahbandar personnel to manage ships at PPS Nizam Zachman, implementing PP No. 11 of 2023 Article 1 so as to create an even distribution of the catch and the number of ships entering the port and dredging pond waters regularly to make it easier for ships to carry out activities at the port.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
