Judul: Studi Keragaman Genetik Kerang Darah (Anadara granosa) Berdasarkan Cytochrome Oxydase Subunit I (COI)
Abstrak: Blood Cockle (Anadara granosa, Linneaus 1758) is a cosmopolitan bivalve inhabiting intertidal zone with sandy mud sediment. As a filter feeding organism, the blood cockle uptakes both organic and inorganis materials, including heavy metals. Heavy metal may cause genetic changes; consequently, those give rise to genetic diversity. This research is aimed at analyzing genetic variations based on Cytochrome Oxidase Subunit I (COI) gene in blood cockle (A. granosa) from Banten coastal waters. DNA extraction procedure used CTAB (Chloroform Isoamil Alkohol) methods, followed by amplification using specific primers and sequencing. Sequencing product of A. granosa samples was 606 bp. A. granosa and other bivalve COI gene sequences were aligned. Bivalves from Family Arcidae such as Tegillarca granosa, Anadara diluvii, Anadara crebricosata, Anadara vellicata, Anadara sativa, Anadara pilula, Diluvarca ferruginea and Scapharca globosa were used as ingroup, while others such as Cucullaea labiata, Didimacar tenebrica, and Glycymeris rotunda were treated as outgroup. Those groups were acquired from GenBank. Molecular Evolutionary Genetics Analysis Version 4 (MEGA 4.0) program was applied for alignment procedure. Phylogenetic tree showed a distict cluster between ingroup (A. granosa, T. granosa, A. diluvii, A. crebricosata, A. vellicata, A. sativa, A. pilula, D. ferruginea, S. globosa) and outgroup (C. labiata, D. tenebrica, G. rotunda). There were 17 diagnostic nucleotide characterized A. granosa.

Judul: Karakteristik Gen Cytochrome Oxidase Subunit I (COI) pada Kerang Bulu (Anadara antiquata Linn.) asal Perairan Panimbang dan Bojonegara, Provinsi Banten
Abstrak: Anadara antiquata is an intertidal bivalve belongs to Arcidae Family. Its distribution in Indonesia is widespread. Its play role both in economy and ecology. Based on genetic database from GenBank, there is no genome data of A. antiquata from Indonesia. Therefore, to accomplish information on this hairy cockle, this research was aimed at characterizing cytochrome oxidase subunit I (COI) in cockle (Anadara antiquata linn.) from Banten (Panimbang and Bojonegara). Hairy cockle samples were collected from Panimbang and Bojonegara. Those were extracted for DNA analysis. DNA extraction and amplification process were followed with DNA sequencing of COI gene that produced 607 nucleotides (nt). The product was analyzed using software MEGA 4.0 and aligned with some sequences from GenBank database. This study was able to characterize A. antiquata COI gene which product was 382 nt using alignment method of Clustal W.

Judul: Ketimpangan Ekonomi Nasional di Era Pemerintahan Susilo Bambang Yudhoyono (2004-2014) : Perspektif Ekonomi Politik
Abstrak: Kesejahteraan masyarakat merupakan cita-cita luhur bangsa yang harus diwujudkan sebagaimana tertera dalam Mukaddimah Undang-Undang Dasar Negara Republik Indonesia tahun 1945 (UUD 45). Sejak masa kemerdekaan Indonesia, pembangunan ekonomi untuk kesejahteraan masyarakatnya mengalami pasang-surut. Era Reformasi cenderung erat kaitannya dengan pemerintahan Presiden Susilo Bambang Yudhoyono (SBY). Sepuluh tahun menjalani roda pemerintahan, perekonomian Indonesia cenderung positif di bawah kepemimpinan SBY, namun tidak diikuti dengan peningkatan kesejahteraan rakyatnya.1 Ini dibuktikan dengan meningkatnya ketimpangan yang ditandai dengan meningkatnya indeks gini menjadi 0,41 pada 2014 (sebelumnya hanya 0,36 pada 2004).2 Oligarki ekonomi diduga menjadi salah satu penyebab adanya percepatan ketimpangan. Sejak reformasi, trasnformasi struktural perekonomian Indonesia yang diharapkan lebih berkeadilan ternyata mengalami hambatan akibat tren penguasaan aset dan akses terhadap sumberdaya ekonomi. Analisis ekonomi politik digunakan dalam penelitian ini untuk mengeksplorasi hal-hal yang terkait dengan kebijakan pembangunan ekonomi nasional di bawah pemerintahan Presiden SBY. Hasilnya ialah ada beberapa faktor yang menyebabkan terjadinya ketimpangan ekonomi nasional seperti manfaat pertumbuhan ekonomi yang positif nyatanya hanya dinikmati oleh segelintir masyarakat,dan lain sebagainya.
