Judul: Rancang Bangun Sistem Pendataan Perikanan Tangkap di Kabupaten Sukabumi, Jawa Barat
Abstrak: Good data collection system is important factor in gaining an efficiency that will create an advantage, especially on fisheries data collection. However, fisheries data collection system in Sukabumi is still very simple and done with the manual system. Seeing the potential of Sukabumi fisheries, we need a system design of effective and efficient data collection in order to improve the performance of any part of the ports in Sukabumi. This study aimed to design a system of web-based fisheries database that can be accessed by any institution in Sukabumi and can be used as consideration in decision-making on fishery policy in Sukabumi. The analysis used is the development of a system that aims to produce an effective operating system based on the information needs of the user by using My SQL (Structure Query Language) and PHP (Hypertext Processor). The results of the analysis have shown that the fisheries data collection system can be identified on data of Sukabumi into 10 parts, production, ports, fishing, boats, type of boats, fishing gear, kind of catch, KUB (Joint Business Group), fisheries enterprise and managing user menu. The web-based application data management process is expected to be more structured and more efficient so as to support the fishing activities in Sukabumi.

Judul: Sistem Informasi Pengelolaan Sumberdaya dan Lingkungan Perikanan Tangkap di Palabuhanratu, Sukabumi
Abstrak: Undang-undang Republik Indonesia Nomor 45 Tahun 2009 tentang Perikanan menyatakan bahwa pemerintah dan pemerintah daerah wajib menyusun dan mengembangkan suatu sistem informasi bidang perikanan agar dapat diakses dengan mudah dan cepat oleh seluruh masyarakat. Namun, DKP Kabupaten Sukabumi dan PPN Palabuhanratu belum memiliki sebuah sistem informasi perikanan yang menjawab kebutuhan masyarakat. Selain itu, data lingkungan perairan Teluk Palabuhanratu juga tidak lengkap, padahal data tersebut berguna untuk memprediksi daerah penangkapan ikan. Oleh karena itu, penelitian ini bertujuan untuk membuat suatu sistem informasi pengelolaan sumberdaya dan lingkungan perikanan tangkap di Palabuhanratu, Sukabumi. Metode penelitian ini menggunakan model pengembangan sistem sekuensial (the waterfall model) dimana tiap tahap harus selesai sebelum beralih ke tahap selanjutnya. Aplikasi yang dihasilkan dari penelitian ini diberi nama Sistem Informasi Perikanan Tangkap (SIPERTA). Aplikasi ini dapat diakses pada http://siperta.16mb.com. Menu utama pada aplikasi ini adalah menu sumberdaya ikan, menu lingkungan, dan menu teknologi.

Judul: Penapisan Inhibitor Tirosinase pada Empat Spesies Famili Asteraceae Chrysantemum morifolium R, Gerbera jamesonii A, Dahlia rosea Cav, dan Tagetes erecta.
Abstrak: The research was conducted to screen the potency of tyrosinase inhibitor from 4 species of Asteraceae family. The screening was performed on the leaves and flowers of Chrysantemum morifolium R, Gerbera jamesonii A, Dahlia rosea Cav, and Tagetes erecta. The samples were dried and then extracted with nhexane, ethyl acetate, and methanol. The inhibition activity was tested by a microplate reader spectrophotometer in 492 nm. The ethyl acetate extract of D. rosea Cav flower was the most potent tyrosinase inhibitor (IC50 for monophenolase 18.42 μg/mL and for diphenolase 687.79 μg/mL) compared with the other Asteraceae species. The most active essential oils as inhibitor of tyrosinase was obtained from T. erecta flower (IC50 for monophenolase 1882.62 μg/mL and for diphenolase 1884.33 μg/mL). Positive control used was kojic acid with IC50 value of 11.02 μg/mL for monophenolase and 84.19 μg/mL for diphenolase. Fractionation of the extract by preparative thin layer chromatography with chloroform as mobile phase gave 12 fractions. The most active fraction had IC50 of 5.55 μg/mL for monophenolase and 109.96 μg/mL for diphenolase, and was identified as flavonoid.
