Judul: Squid Fishery Development Strategy at the Tanjung Luar Fish Landing Base, East Lombok Regency
Abstrak: Penurunan sumber daya cumi-cumi di perairan Selat Alas dikhawatirkan akan berdampak kepada kegiatan perikanan cumi-cumi di PPI Tanjung Luar, sayangnya informasi mengenai kegiatan perikanan cumi-cumi di PPI Tanjung Luar masih belum banyak dikaji secara ilmiah. Penelitian bertujuan untuk mendeskripsikan kondisi perikanan cumi-cumi, menganalisis sistem produksi dan pemasaran perikanan cumi-cumi, dan menyusun strategi pengembangan perikanan cumi-cumi di kawasan PPI Tanjung Luar, Kabupaten Lombok Timur. Metode pengumpulan data yang digunakan adalah pengumpulan data statistik dan wawancara dengan teknik purposive sampling. Analisis data yang digunakan berupa analisis deskriptif, pendekatan sistem, dan SWOT. Hasil penelitian menunjukkan bahwa nelayan menggunakan pancing dan payang dengan kapal berukuran <5 GT untuk menangkap cumi-cumi. Mesh size kantong payang yang digunakan berukuran 0,5 inci. Output yang dikehendaki dalam sistem produksi dan pemasaran cumi-cumi adalah sumber daya cumi-cumi terjaga, harga stabil dan layak, pendapatan nelayan meningkat, dan PAD meningkat. Alternatif strategi yang dapat diterapkan untuk pengembangan perikanan cumi-cumi di kawasan PPI Tanjung Luar, di antaranya adalah melakukan penyuluhan kepada nelayan terkait pentingnya menjaga kelestarian sumber daya ikan dan pemahaman mengenai kondisi cuaca, membuat aturan dan melakukan pengawasan terkait mesh size kantong payang dan ukuran layak tangkap cumi-cumi, dan pengadaan cold storage sebagai upaya pengendalian jumlah cumi-cumi di pasaran., It is feared that the decline in squid resources in the waters of Alas Strait will have an impact on squid fishing activities at the Tanjung Luar PPI. This study aims to describe the condition of the squid fishery, analyze the production and marketing systems of the squid fishery, and formulate strategies for the development of the squid fishery in the Tanjung Luar PPI area, East Lombok Regency. The data collection method used involves statistical data collection and interviews with a purposive sampling technique. Analysis of the data is conducted using descriptive, systems approach, and SWOT. The results showed that the fishermen used fishing rods and payang with vessels <5 GT to catch squid. The mesh size of the payang bag used was 0.5 inches. The desired output in the production and marketing system of the squid is that squid resources are maintained, stabilize and set reasonable prices, fishermen's income increases, and PAD increases. Alternative strategies that can be implemented for the development of squid fisheries in the Tanjung Luar PPI area include conducting counseling to fishermen regarding the importance of preserving fish resources and understanding weather conditions, making rules and carrying out supervision regarding payang bag mesh sizes and proper sizes for catching squid, and procuring cold storage as an effort to control the number of squid on the market.

Judul: Technical Performance of Squid Attractor in East Lombok Regency
Abstrak: Penangkapan cumi-cumi di Kabupaten Lombok Timur saat ini mengalami penurunan hasil tangkapan dikarenakan jumlah armada yang meningkat dalam waktu cepat. Perlu adanya pengayaan terhadap sumberdaya cumi-cumi dengan diadakannya atraktor cumi-cumi. Tujuan penelitian ini yaitu mendeskripsikan unit penangkapan cumi-cumi, mendeskripsikan keragaan teknis atraktor cumi-cumi meliputi konstruksi dan spesifikasinya dan mengobservasi keragaan cumi-cumi berdasarkan kondisi lingkungan dan hasil tangkapan cumi-cumi di sekitar atraktor pada Perairan Kabupaten Lombok Timur. Analisis dilakukan dengan mendeskripsikan perikanan cumi-cumi, keragaan teknis atraktor cumi-cumi, dan hasil observasi kondisi atraktor. Hasil penelitian menunjukkan kegiatan penangkapan cumi-cumi di Kabupaten Lombok Timur menggunakan alat tangkap payang dan pancing cumi. Atraktor cumi-cumi jenis drum memiliki ukuran lebih kecil dan tidak memiliki baut seperti jenis fiberglass. Komponen yang dipasang kedua jenis atraktor diantaranya tali rami dan besi penyangga. Arus perairan menyebabkan kerusakan pada badan atraktor dan besi penyangga. Hasil tangkapan cumi-cumi di sekitar atraktor lebih besar 2 kali lipat dibandingkan hasil tangkapan yang berada di luar area atraktor. Berdasarkan hasil tangkapan yang diperoleh selama 4 minggu, total hasil tangkapan di sekitar atraktor mencapai 34,1 kg, sementara total hasil tangkapan di luar area atraktor mencapai 16,3 kg., Squid fishing in East Lombok Regency is currently over exploited due to the rapid increase in the number of fleets. It is necessary to enrich the squid resources with squid attractors. The objectives of this study were to describe the squid fishing unit, describe the technical performance of the squid attractor including its construction and specifications and observe the squid behavior based on environmental conditions and squid catches around the attractor in the waters of East Lombok Regency. Analysis was conducted by describing the squid fishery, technical performance of the squid attractor, and observation of the attractor condition. The results showed that squid fishing activities in East Lombok Regency use payang, squid fishing rod, and tonda fishing rod. Drum-type squid attractors have a smaller size and do not have bolts like fiberglass types. Components installed in both types of attractors include hemp rope and iron supports. Water currents cause damage to attractor body and supporting iron. The catch of squid around attractor is 2 times greater than the catch outside the attractor area. based on the catch obtained for 4 weeks, the total catch around the attractor reached 34.1 Kg, while total catch outside the attractor area reached 16.3 Kg.

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.
