Judul: Kajian Kelayakan Usaha Budidaya Gracilaria dan Evaluasi Kinerja Kelompok “Budidaya Rumput Laut Serang Utara” di Kabupaten Serang
Abstrak: The utilization of marine and fishery potential has the economic prospect for Indonesia. Indonesia waters blessed with abundant and diverse of marine living resources. One of those marine resources is seaweeds. From the various type of seaweed that existed in Indonesia waters, Gracilaria is one of the seaweed with high economical values in Indonesia, especially for the manufacture of agar (jelly). Seaweed is one of commodity that cultivated in the sea and ponds, and become one of international commodities in trading. Serang district is one of the regions where the Gracilaria utilization is not yet optimized. Data in 2010 shows, Serang revenues of approximately 19.25 billion rupiah with the total land used about 500 hectares from 5,000 hectares of total land. 4,500 hectares that remained unutilized with potential revenue of Rp. 101.25 billion, or in other words the lost amount of potential revenue in Serang district is up to 5-fold or 80% of the total potential revenue. This study aims to determine if seaweed species of Gracilaria worth to cultivate and to measure the work performance carried out by the group in their seaweed business development. This study is a study conducted in Serang district which has a potential development of Gracilaria species. In this study, the research used quantitative approach. Data is collected using primary and secondary data. The sampling technique used was purposive method. The sample in this study were all members of the group "Budidaya Rumput Laut Serang Utara" and the customer of business group "Budidaya Rumput Laut Serang Utara". The feasibility study of seaweed cultivation using secondary data sources, while the assessment of the work performance group "Budidaya Rumput Laut Serang Utara" uses primary data with BSC method which based on survey results, as well as secondary data for the assessment of multiple perspectives. The results shows, based on the analysis of the feasibility of seaweed cultivation of Gracilaria, the market and marketing aspects, technical aspects, financial aspects, political and socio-economic aspects, environmental aspects, aspects of human resources and legal aspects gives positive results. While the results of work performance of each BSC perspective shows: (1) The perspective of membership (83.42%), (2) Perspective of Learning and empowerment (71.83%), (3) Internal business process perspective (55.8%), (4) Financial Perspective (39.23%). After multiplication by each of the perspective, the achievement of the overall performance is KBRLSU 63.72%, or still below 80%.

Judul: Pra studi kelayakan industri pengolahan rumput laut(Gracilaria sp.) di Kabupaten Takalar, Propinsi Sulawesi Selatan
Abstrak: Indonesia sebagai negara kepulauan mempunyai potensi sumberdaya perikanan yang besar. Salah satu sumberdaya perikanan yang mempunyai nilai ekonomis cukup tinggi adalah rumput laut (Seaweed) jenis Gracilaria. Rumput laut jenis ini dalam bentuk kering merupakan komoditi ekspor dan setelah diolah menghasilkan agar-agar yang dibutuhkan oleh banyak industri, antara lain: industri makanan, farmasi dan industri kosmetik. Kebutuhan dunia akan produk hasil olahan rumput laut, khususnya agar-agar, pada dasawarsa mendatang diperkirakan akan meningkat pesat. Perdagangan dunia agar-agar (baik bahan mentah maupun produk jadi) dalam volume dan nilai terus meningkat. Diperkirakan setiap tahun diperdagangkan sekitar 10.000 ton bahan mentah dan 3.500 ton produk jadi. Seluruh negara komsumen, kecuali Jepang, sekitar 80 - 90% dari volume kebutuhannya dipe- nuhi dari impor. Kebutuhan agar-agar dalam negeri juga mengalami peningkatan seiring dengan pertambahan jumlah penduduk dan perkembangan era industrialisasi. Volume impor agar-agar pada tahun 1990 mencapai 406 ton dengan nilai US$3.795.000 naik 10% dari volume impor tahun sebelumnya. Kabupaten Takalar, Propinsi Sulawesi Selatan memili- ki wilayah pantai sepanjang 108 km dengan luas areal tam- bak mencapai 2.839 ha dan mampu memproduksi rumput laut jenis Gracilaria kering sebanyak 6.000 ton per tahun. Tujuan studi ini adalah untuk mengetahui kemungkinan (layak atau tidak) proyek industri pengolahan rumput laut jenis Gracilaria dilaksanakan di Kabupaten Takalar. Metode studi yang digunakan adalah studi kasus dan studi pustaka, dibantu dengan beberapa asumsi. Studi ini menghasilkan pra kelayakan industri peng- olahan agar-agar dari rumput laut jenis Gracilaria di Kabupaten Takalar…dst

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
