Judul: Daerah Penangkapan Rajungan di Teluk Banten
Abstrak: Nilai jual rajungan yang tinggi mendorong peningkatan upaya penangkapan dapat menyebabkan overfishing. Overfishing dapat dicegah dengan menetapkan ukuran tangkapan dan daerah penangkapan. Namun, ukuran minimum rajungan yang seragam untuk penangkapan di seluruh Indonesia (lebar karapas 10 cm (CW) sesuai Permen KP No. 56/2016) bisa tidak sesuai untuk setiap lokasi. Ukuran dapat ditentukan dengan mempertimbangkan aspek biologis rajungan. Konflik pemanfaatan daerah penangkapan ikan dapat terjadi di antara nelayan karena spesies sasarannya sama. Oleh karena itu, penelitian ini bertujuan untuk menentukan ukuran minimum rajungan, daerah penangkapan yang potensial, dan alokasi untuk setiap jenis alat tangkap rajungan di Teluk Banten. Data ukuran rajungan dikumpulkan dengan sensus dari kapal penangkap ikan yang dipilih dengan menggunakan accidental sampling. Tingkat kematangan gonad (TKG) ditentukan di laboratorium untuk sampel rajungan yang telah dipilih dengan menggunakan accidental sampling. Daerah penangkapan yang potensial dan alokasi alat tangkap ditentukan berdasarkan CPUE dan porsi rajungan yang layak tangkap dalam hasil tangkapan. Sampel rajungan yang diukur sebanyak 5077 sampel dan yang dibedah sebanyak 81 sampel. Sampel rajungan jantan didominasi oleh rajungan dengan TKG III sedangkan sampel betina didominasi oleh TKG IV. Ukuran layak tangkap rajungan jantan di Teluk Banten adalah 11.3 cm (CW) sedangkan untuk rajungan betina adalah 9,4 cm (CW). Namun untuk lebih memastikan kelestarian sumberdaya rajungan, ukuran rajungan yang boleh ditangkap di Teluk Banten diusulkan minimum 11,0 cm (CW). Zona B, D dan F diusulkan untuk dialokasikan sebagai daerah penangkapan untuk jaring rajungan sedangkan zona A dan G untuk bubu lipat.

Judul: Dampak Penangkapan Rajungan (Portunus pelagicus) terhadap Target dan Non Target Spesies di Perairan Cirebon dan Sekitarnya
Abstrak: Kondisi tangkap lebih mengancam keberlanjutan stok rajungan di perairan. Rendahnya selektivitas alat tangkap mengakibatkan tertangkapnya hasil tangkapan sampingan (bycatch) dalam jumlah cukup besar. Penelitian ini bertujuan: (1) mendeskripsikan unit penangkapan rajungan yang berbasis di Desa Gebang Mekar Kabupaten Cirebon; (2) mengevaluasi status stok rajungan; dan (3) mengevaluasi dampak penangkapan rajungan, khususnya terhadap sumber daya ikan non target tangkapan. Data dianalisis dengan beberapa metode yakni analisis mortalitas dan laju eksploitasi, ukuran layak tangkap, serta jenis dan proporsi hasil tangkapan. Hasil penelitian menunjukkan unit penangkapan rajungan di lokasi studi yaitu jaring kejer sebanyak 102 unit, bubu lipat 25 unit, jaring arad 100 unit, dan garuk 100 unit. Laju eksploitasi (E) rajungan jantan 0,66 dan betina 0,60 per tahun. Rajungan ukuran boleh ditangkap (legal size) oleh jaring kejer berjumlah 97%, bubu lipat 97%, jaring arad 83%, dan garuk 19%. Bycatch jaring kejer, bubu lipat, jaring arad, dan garuk sebagian besar belum memenuhi ukuran layak tangkap. Proporsi hasil tangkapan sampingan jaring kejer 51%, bubu lipat 55%, jaring arad 95%, dan garuk 59%. Indeks keragaman Shannon – wiener (H’) hasil tangkapan jaring arad sebesar 3,52, jaring kejer 3,37, bubu lipat 1,82, dan garuk 1,52. Pemerintah perlu meningkatkan penyadaran nelayan agar tidak menggunakan alat tangkap jaring arad dan garuk karena melanggar hukum dan berdampak negatif terhadap sumber daya ikan., Over fishing threatens the sustainability of crab stocks in the waters. The low selectivity fishing gears resulted in a relatively large number of caught bycatch species. This study aims to describe the blue swimming crab fishing unit based in Gebang Mekar Village, Cirebon District; to evaluate the status of the crab stock, and to evaluate the impact of crab fishing, especially on non-target species. The analyses of mortality and exploitation rate, allowable (legal) catch size, and catch composition were conducted. The results showed that the fishing units of blue swimming crab at the study site were 102 units of kejer nets, 25 units of collapsible traps, 100 units of arad nets, and 100 units of dredged nets. The exploitation rate (E) of male crabs was 0.66 and for females was 0.59 per year. For the kejer nets 97% of the crabs caught were in the legal size, 97% for collapsible traps, 83% for arad nets, and 19% for dredged nets. Most of the bycatch of kejer nets, collapsible traps, arad nets, and dredged nets did not meet the allowable catch size. The proportion of the bycatch for kejer nets was 51%, collapsible traps was 55%, arad nets was 95%, and dredged nets were 59%. Shannon – wiener diversity index (H’) of arad nets catches were 3.52, kejer nets (3.37), collapsible traps (1.82), and dredged nets (1.52). Government should disseminate to fishers not to used arad, and dredged nets for crabs fishery due to illegal fishing gears and negative impact on the fish resources.

Judul: Pengembangan distribusi ILOS multimedia (ILOSmedia)
Abstrak: The development of open source softwares is still going rapidly nowadays, including open source operating systems for desktop computer, netbook, tablet PC, and smartphone. The open source operating systems have considerable contribution to open source software. Linux is an open source operating system that continues to grow since 1991. The characteristics in general Linux are free, can be distributed freely, and free to make changes in it. Linux in its development is divided into several distributions. Each distribution is made as a specific goal so that the operating system can focus on running the desired functions, such as multimedia, networking, education, etc. The objective of of this research is to develop and evaluate the ILOS distribution for multimedia by providing multimedia of open source packages. ILOSmedia uses Ubuntu10.10 and Remastersys as a tool to remaster. ILOSmedia is developed by installing multimedia packages that have been obtained based on the results of questionnaires from 30 respondents from three communities, which are KPLI Bogor, Linux.com forums, and Kaskus.us forums. ILOSmedia also uses the Realtime kernel as kernal Mutimedia. ILOSmedia testing is performed by 11 students of Computer Science who are members of FOKERZ community. The testing process is performed by executing ILOSmedia via live-cd and filled in a questionnaire. The test result shows that ILOSmedia has hardware compatibility on notebook and PC with good performance. As much as 72.727% of respondents believe that the size of the installer ILOSmedia of 1.34 GB and a minimum 10GB hard drive is normal. ILOSmedia has multimedia packages complete with the percentage completeness according to respondents is 45.455% are very complete and 54.545% are complete. Boot speed ILOSmedia have an average of 28.87 seconds and 90.91% of respondents consider that ILOSmedia have a desktop environment that is easy navigation
