Judul: Analisis Bio-ekonomi Pengelolaan Sumberdaya Spiny Lobster (Panulirus spp) di Perairan Wonogiri, Jawa Tengah
Abstrak: Spiny lobster telah dikenal dan dikonsumsi manusia, serta memiliki nilai ekonomis tinggi. Di Perairan Wonogiri terdapat sumberdaya spiny lobster yang potensial. Informasi tentang beberapa faktor diperlukan agar eksploitasi spiny lobster di Perairan Wonogiri dapat berjalan secara optimal, baik secara biologi maupun ekonomi. Penelitian ini bertujuan menginventarisasi alat penangkap spiny lobster dan menentukan tingkat pengelolaan sumberdaya spiny lobster yang optimal di Perairan Kabupaten Wonogiri. Penelitian dilaksanakan di Kecamatan Paranggupito Kabupaten Wonogiri tanggal 5-26 Agustus 2004 dan 3 8 Februari 2005 menggunakan metode survei. Analisis data berupa analisis fungsi produksi lestari perikanan tangkap, tingkat pemanfaatan sumberdaya spiny lobster dan bio- ekonomi model statik Gordon-Schaefer. Hasil penelitian menunjukkan bahwa alat penangkap spiny lobster di Perairan Wonogiri adalah 2.747 unit krendet dan 878 unit jaring hampar. Nelayan penangkap spiny lobster berjumlah 304 orang, terdiri atas 73 orang nelayan penuh. 173 orang nelayan sambilan utama dan 58 orang nelayan sambilan tambahan. Nilai maximum sustainable yield (MSY) spiny lobster di Perairan Kabupaten Wonogiri diperoleh sebesar 1.251.57 kg dan effort optimum (EMSY) sebesar 1.769 trip per tahun. Tingkat pemanfatan sumberdaya spiny lobster pada tahun 2004 mencapai 64,89% dengan effort 2.432 trip. Nilai maximum economic sustainable yield (hMESY) sebesar 1.243,22 kg dengan effort (EMESY) sebanyak 1.624 trip per tahun dan rente ekonomi yang diperoleh sebesar Rp94.361.363,00. Melihat kondisi tersebut, pada tahun 2005 perlu pengurangan effort hingga 808 unit, dengan demikian pemanfaatan sumberdaya spiny lobster dapat efisien secara ekonomi dan kelestariannya dapat terjaga.

Judul: Business Analysis of Catching and Sustainable  Lobster Utilization in Pangandaran Regency, West Java
Abstrak: Lobster atau udang karang merupakan salah satu komoditas perikanan unggulan pada pasar domestik maupun ekspor. Stok komoditas lobster saat ini masih bergantung pada alam. Sebagian besar di wilayah pengelolaan perairan Indonesia telah mencapai batas maksimum jumlah tangkapan yang diperbolehkan. Usaha penangkapan lobster sebagai salah satu satu pengelolaan wilayah perairan Pangandaran perlu dikaji untuk mengetahui bagaimana sumberdaya lobster dapat dimanfaatkan secara optimal dan berkelanjutan. Tujuan penelitian ini adalah: (1) mengidentifikasi kondisi biologi lobster di Perairan Kabupaten Pangandaran Jawa Barat; (2) menganalisis kondisi pemanfaatan optimal lobster di Perairan Kabupaten Pangandaran Jawa Barat; (3) menganalisis kelayakan usaha finansial penangkapan lobster di Perairan Kabupaten Pangandaran Jawa Barat; dan (4) menganalisis strategi kebijakan pengelolaan lobster secara berkelanjutan di Kabupaten Pangandaran Jawa Barat. Metode yang digunakan pada penelitian ini yaitu: (1) analisis kondisi biologi lobster; (2) analisis bioekonomi spasial; (3) cost benefit analysis; dan (4) analisis deskriptif kualitatif. Penelitian ini menunjukkan rata-rata lobster yang tertangkap di Kabupaten tidak sesuai dengan ukuran layak tangkap. Tingkat CPUE lobster memiliki nilai yang berfluktuatif, namun terjadi penurunan secara signifikan pada tahun 2021, sehingga alokasi penangkapan optimal yang direkomendasikan yaitu 396 trip/bulan. Berdasarkan hasil analisis, usaha penangkapan lobster layak untuk dijalankan. Adapun strategi kebijakan pengelolaan lobster yang dapat dilakukan agar tetap lestari yaitu dimulai dari pelarangan penangkapan benih bening lobster kemudian diikuti dengan kebijakan lainnya. Perlu dilakukan penelitian lebih lanjut mengenai laju pertumbuhan dan perkembangan biomassa lobster dan pengembangan budidaya lobster di Perairan Kabupaten Pangandaran, Jawa Barat., Lobster or crayfish is one of the leading fishery commodities in the domestic and export markets. Lobster commodity stocks are currently still dependent on nature. Most of the Indonesian water management areas have reached the maximum allowable catch. Lobster fishing as one of the management of the Pangandaran waters area needs to be studied to find out how lobster resources can be used optimally and sustainably. The aims of this study were: (1) to identify the biological conditions of lobsters in the waters of Pangandaran Regency, West Java; (2) analyzing the condition of optimal utilization of lobsters in the waters of Pangandaran Regency, West Java; (3) analyzing the financial feasibility of catching lobsters in the waters of Pangandaran Regency, West Java; and (4) analyze the policy strategy for sustainable lobster management in Pangandaran Regency, West Java. The methods used in this study were: (1) analysis of the biological conditions of the lobsters; (2) spatial bioeconomic analysis; (3) costbenefit analysis; and (4) qualitative descriptive analysis. This research shows that the average size of lobsters caught in the district is not suitable for catching size. The lobster CPUE level has a fluctuating value, but there will be a significant decrease in 2021, so the recommended optimal catch allocation is 396 trip/month the harvest season. Based on the results of the analysis, the lobster-catching business is feasible to run. The lobster management policy strategy that can be implemented to remain sustainable is to start with a ban on catching clear lobster seeds, followed by other policies. It is necessary to carry out further research regarding the growth rate and development of lobster biomass and the development of lobster cultivation

Judul: Pengembangan Sistem Autentikasi Voter pada Central Legitimization Agency Menggunakan Media Mifare Smart Card®
Abstrak: Cryptography becomes one of the important things in the development of electronic voting system. The voting system using internet network technology aims to reduce considerable calculation time as well as necessary human resources. Securing lines of communication between voting machines and servers is needed to communicate securely. The identity of the voters, which is used for authentication voting process is stored in Mifare smart card called identity card. Every identity card which contains unique identification and nomor induk kependudukan will be authenticated in Central Legitimization Agency server. Card identity is hashed with SHA-2 and encrypted with session key to assure that the integrity of data is not changed by others. Session key is distributed from CLA to voting machines which are encrypted with asymmetric RSA algorithm. Only voting machines can decrypt the ciphertext to get the session key as plaintext. The list of the voters who are allowed to vote is stored in the CLA database. The decrypted plaintext must be identical to one of the voters in the voters list, for the voter to be able to vote. Only one vote for each of the voters can be casted. If the time limit is reached, CLA will distribute the vote count to the Central Tabulating Facilities. Considering the complexity in building a complete secure online election voting process, this research is only focused developing a system to authenticate the voter identity in CLA from identity card which is stored in Mifare smart card.
