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: Implementation of Tuna Traceability in Ocean Fishing Port of Nizam Zachman Jakarta
Abstrak: Ikan tuna merupakan salah satu komoditas unggulan ekonomis tinggi dalam industri perikanan. Negara tujuan ekspor tuna meliputi Amerika Serikat, Uni Eropa dan Jepang. Amerika Serikat dan Uni Eropa mengharuskan sistem traceability. Traceability berperan sebagai sistem untuk menelusuri riwayat produk melalui pendokumentasian. Traceability di Indonesia diterapkan sejak tahun 2010 dan dikembangkan oleh Masyarakat dan Perikanan Indonesia (MDPI) di Indonesia Timur. Pelabuhan Perikanan Samudera (PPS) Nizam Zachman adalah salah satu pelabuhan yang berorientasi ekspor ke Amerika Serikat dan Uni Eropa. Namun, berdasarkan survei pendahuluan diketahui bahwa masih terdapat kelemahan pada sistem pendokumentasian dan kegiatan penanganan tuna saat bongkar hingga pendistribusian ke industri pengolahan perikanan tuna. Oleh karena itu, penelitian ini bertujuan: (1) mendeskripsikan penerapan traceability MDPI; (2) mengidentifikasi struktur rantai pasok di PPS Nizam Zachman; (3) menemukan faktor-faktor penghambat penerapan traceability di PPS Nizam Zachman; (4) merekomendasikan tindakan perbaikan implementasi traceability. MDPI memiliki program unggulan IFITT (improving fisheries information and traceability tuna). IFITT berfokus pada informasi perikanan berbasis teknologi untuk memudahkan traceability perikanan tuna. Sistem yang dikembangkan IFITT meliputi spot trace dan tracetales. Rantai pasok perikanan tuna di PPS Nizam Zachman dari kapal penangkap ikan, kemudian didistribusikan ke industri perikanan tuna. Proses rantai pasok melibatkan pelabuhan sebagai fasilitator dan pengawas kegiatan, nelayan sebagai produsen utama dan industri pengolahan berperan sebagai anggota utama. Melalui rantai pasok dapat ditemukan hambatan atau kekurangan mengenai penerapan traceability di PPS Nizam Zachman. Berdasarkan aktivitas rantai pasok dan hasil penilaian tingkat kesesuaian kegiatan perikanan tuna di PPS Nizam Zachman didapatkan kegiatan yang menghambat traceability. Kegiatan-kegiatan tersebut berupa pengisian e-logbook, penanganan tuna saat bongkar, penanganan ikan tuna di industri pengolahan perikanan tuna, dan industri pengolahan perikanan tuna belum sepenuhnya digitalisasi. Tindakan perbaikan yang dapat dilakukan yaitu: 1) sosialisasi, pelatihan monev dan pemantauan aktivitas nelayan; 2) meningkatkan pemahaman syarat-syarat dasar traceability terkalit mutu ikan tuna dan adanya pengawasan mutu di lapang secara berkala; 3) kolaborasi pemerintah dengan LSM maupun asosiasi industri perikanan tuna., Tuna is one of high economical commodity in fisheries industrialization program. Exporter country of Indonesia tuna are United states, European Union, and Japan. The United States and European Union have decreed the traceability system. Traceability plays a role as a system to trace product history by documentation. Traceability system in Indonesia has been applied since 2010 and developed by Masyarakat dan Perikanan Indonesia (MDPI) in Eastern Indonesia. Nizam Zachman Fishing port is one of fishing port export oriented to United states and European union. But, based on the survey shows that documentation system, tuna handling when loading until distribution process to the processing industry are still low. The objective of this study were: (1) to describe the application of traceability system by MDPI, (2) to identify structure of rantai pasok in Nizam Zachman Fishing port, (3) to formulate obstacle factors of traceability, (4) to recommend improvement action of traceability implementation MDPI has program called IFITT (improving fisheries information and traceability tuna). IFITT focuses on technlogy based fisheries information to facilitate traceability of tuna fisheries. The systems developed by IFITT are spot trace and tracetales. Tuna supply chain in Nizam Zachman Fishing port Zachman was from fishing boats, then distributed

Judul: Mathematical model of Hematopoietic Stem Cell in Chronic Myelogenous Leukemia with and without Therapy
Abstrak: Leukemia or blood cancer is a diverse group of neoplastic disease, characterized by the multiplication of abnormal leukocytes or malignant transformation of blood-forming cells in bone marrow and lymphoid tissues. One of the most common types of leukemia is Chronic Myelogenous Leukemia (CML), which is usually diagnosed by the presence of certain chromosomal abnormalities, the so-called Philadelphia chromosome (Ph). One of the treatments of CML is Granulocyte Colony-Stimulating Factor (G-CSF). In this paper, we discuss two Hematopoietic Stem Cell (HSC) models, i.e. HSC without treatment and HSC with G-CSF treatment. The model of HSC without treatment included three equations representing the dynamics of HSC, leukocyte and platelet. Whereas, the model of HSC with G-CSF treatment includes the previous three equations and adds two more equations representing G-CSF injection and G-CSF circulation. The stability behavior of the system approaching the equilibrium points in the simulation study is carried out using Mathematica 7.0. The simulation results show that the G-CSF treatment can successfully decrease the number of HSC, which means reducing the CML.
