Abstrak: Indonesia is one of tuna exporters. World demand to fishery product of Indonesia especially tuna increases year by year. PPSNZJ is the biggest harbor in Indonesia and expected to be center of fishery product market especially tuna in Indonesia. This research aimed to analyse tuna production, analyse facility needs and decide the strategy of tuna industry development. Primary data were obtained from interview and secondary data were obtained from observation and literature. The result of this research were that production of tuna during 2008-2012 increased 34,28%. The amount of tuna which were imported from other places to PPSNZJ during 2008-2012 were 9,7 %. The export distribution were 64,49%, regional distribution were 45% and local distribution were 53,88%. From 2008 to 2012 tuna production rose in average 14,8% per year. The special facilities for tuna in PPSNZJ which needed to be repaired were TLC, wharf, ice factory and cold storage. The effort which needed to be made during developing of tuna industry in PPSNZJ were expanding market, increasing the quality of human resource and special facility of tuna and cooperating with foreign enterprise.

Judul: Deskripsi Rantai Pasok Ikan Tuna  (Studi Kasus PT Awindo International di Pelabuhan Perikanan Samudera Nizam Zachman Jakarta)
Abstrak: Ekspor ikan tuna Indonesia cenderung meningkat selama lima tahun terakhir. PT AWIndo International merupakan salah satu industri ikan tuna di PPS Nizam Zachman Jakarta (PPSNZJ). PT AWIndo belum menerapkan manajemen rantai pasok. Tujuan dari penelitian ini meliputi : 1) mengidentifikasi rantai pasok ikan tuna yang terjadi di PT AWIndo 2) menganalisis peran PPSNZJ dalam kegiatan rantai pasok ikan tuna. Metode yang digunakan dalam penelitian ini adalah studi kasus. Teknik pengumpulan data dengan purposive sampling. Analisis data terdiri atas analisis manajemen rantai pasok ikan tuna pada PT AWIndo dan analisis peran PPSNZJ terhadap rantai pasok ikan tuna. Hasil penelitian menunjukkan bahwa pelaku rantai pasok ikan tuna di PT AWIndo terdiri dari nelayan pemilik, transit sheed, PT AWIndo, Trio Eagle Logistik, agen luar negeri, supermarket, konsumen akhir. Secara umum rantai pasok ikan tuna sudah baik namun masih belum optimal. Sehingga peningkatan performa penting dilakukan agar rantai pasok ikan tuna dapat berjalan dengan lancar. Pengelola PPSNZJ terdiri atas UPT dan Perum Perindo Cabang Jakarta. Keduanya berperan penting dalam mendukung rantai pasok ikan tuna. Peran kedua lembaga ini lebih kepada pelayanan jasa dan fasilitas., The export of tuna Indonesia increase during the last five years. PT AWIndo International is one of the tuna industry in PPS Nizam Zachman Jakarta (PPSNZJ). PT AWIndo has not implemented supply chain management. The purpose of this research are : 1) identify supply chain tuna in PT AWIndo 2) analyzes the role of PPSNZJ in supply chain tuna. The methods used in this research is a case study. Data was collected by purposive sampling. Data analysis consisted of analysis of supply chain management of tuna on PT AWIndo and analysis of the the role of PPSNZJ on tuna supply chain. The results showed that the actors of tuna supply chain of PT AWIndo are the fishermen, transit sheed, PT AWIndo, Trio Eagle Logistik, foreign agents, supermarkets, the end customer. In general, the tuna supply chain already good, but it is not optimal. Performance improvement is important so tuna supply chain can be well. Management of PPSNZJ consist of UPT and Perum Perindo Jakarta. Both are important in supporting tuna supply chain. The role of the institution is espescially to services and facilities.

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.
