Judul: Eksplorasi Dinamika Keterkaitan Social-Ecological System Perikanan Lobster di Pesisir Kabupaten Pangandaran, Provinsi Jawa Barat
Abstrak: Lobster merupakan komoditas ekonomis penting yang potensial di pesisir Pangandaran. Pengelolaan sumberdaya lobster dalam kerangka Social-Ecological System (SES) di pesisir Pangandaran belum teridentifikasi dengan baik. Penelitian ini bertujuan untuk memetakan dan menganalisis dinamika keterkaitan Social-Ecological System (SES) perikanan lobster (Panulirus spp.) dengan komponen-komponen berupa resources systems (RS), resources units (RU), resources actors (RA), dan resources governance (RG) sebagai input untuk merumuskan strategi pengelolaan perikanan lobster yang berkelanjutan di pesisir Pangandaran. Pengambilan data dilakukan pada bulan Mei hingga Juni 2023 di Kecamatan Cimerak, Kabupaten Pangandaran. Interaksi keterkaitan yang kuat terjadi pada hubungan antar komponen RA dan RS dimana perubahan interaksi dari keduanya dapat mengakibatkan adanya perubahan pada komponen lainnya., Lobster is a potentially important economic fisheries commodity on the coast of Pangandaran. Lobster fisheries management using the Social-Ecological System (SES) framework on the Pangandaran coast has not been well identified. This research aims to map and analyze the dynamics irrelationship between the Social-Ecological System (SES) of lobster (Panulirus spp.) fisheries with the components of resource systems (RS), resource units (RU), resource actors (RA), and resource governance ( RG) as input for developing a sustainable lobster fisheries management strategy on the Pangandaran coast. Data was collected from May to June 2023 in Cimerak District, Pangandaran Regency. Strong interrelated interactions occur in the relationship between RA and RS components where changes in the interaction of the two can result in changes in the other components.

Judul: Eksplorasi Dinamika Keterkaitan Social-Ecological System Perikanan Lobster di Pesisir Kabupaten Garut, Provinsi Jawa Barat
Abstrak: Lobster (Panulirus spp.) adalah salah satu komoditas yang memiliki nilai jual yang tinggi. Indonsesia merupakan salah satu negara di dunia yang melakukan ekpor lobster dengan posisi ke-17 di dunia. Sedangkan di tingkat ASEAN, Indonesia merupakan eksportir utama lobster dunia. Tujuan penelitian ini adalah memetakan sub sistem dan dinamika keterkaitan antar sub-sistem social-ecological system (SES) perikanan lobster yang terdiri dari resources system (RS) ekosistem perairan Kabupaten Garut, resources unit (RU) perikanan lobster, resources actors (RA) dan resources governance (RG) di perairan Kabupaten Garut. Penelitian ini dilaksanakan mulai bulan Mei hingga Juni 2023. Komponen SES yang memiliki hubungan sangat kuat adalah RU dengan RA. Hubungan antara RA yang memanfaatkan sistem RS dan RU diatur dengan sistem tata kelola di pesisir Kabupaten Garut (RG)., Lobster (Panulirus spp.) is one commodity with high selling value. Indonesia is one of the countries in the world that exports lobster with the 17th position in the world. While at the ASEAN level, Indonesia is the world's main lobster exporter. The purpose of this study is to map the sub-systems and the dynamics of interrelationships between sub-systems of the social-ecological system of lobster fisheries consisting of the resource system (RS) of the Garut Regency water ecosystem, resource units (RU) of lobster fisheries, resource actors (RA) and resource governance (RG) in Garut Regency waters. This research was conducted from May to June 2023. SES components that have a very strong relationship between RU and RA. Relationship between RA using RS and RU regulated with the coastal governance system in Garut district (RG).

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.
