Judul: Sistem Informasi Sebaran Ikan Ekonomis Penting di Indonesia Berbasis Web
Abstrak: Regulations of the Republic of Indonesia Number 45 of 2009 stated that government and local government have to establish information system of fisheries so that the fisheries information can be easily and quickly accessed by the community. However, in particular information systems of fisheries that contain distribution and statistical data of economically important fishes in Indonesia are still less than optimal. The purpose of this research is to build the application of information system that contains the spatial distribution of economically important fishes in Indonesia and to determine the distribution of shrimp, tuna, skipjack tuna and bullet tuna based on statistical data of marine capture fisheries. The result of this study is web-based application called Information System of Distribution of Economically Important Fishes in Indonesia. This application can be accessed at http://siikan.site90.net. The main information presented in this application is time series of fisheries statistical data from 2003 to 2011 based on province in Indonesia. Through this information system, it can be seen that the shrimp, skipjack tuna and bullet tuna are found in all provinces in Indonesia, while the tuna are not found in the province of Riau, Riau Islands, Bangka Belitung Islands, Jambi, South Sumatra, and Central Kalimantan.

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: Katalis Eterifikasi Gliserol Berbasis Poli–(asam stirena sulfonat) dari Limbah Styrofoam.
Abstrak: Styrofoam waste can be converted to poly–(sulfonate styrene acid) (PSSA) that can be used as catalyst. The objective of this research is to get PSSA that can catalyze the etherification of glycerol and benzyl alcohol. The styrofoam waste was converted to PSSA by reacting with H2SO4 98% (as sulfonation agent) and P2O5 (as sulfonation catalyst) at 40 °C for 6 hours. Characterizations of PSSA included functional groups, sulfonation levels, water swelling, and thermal stability. The yield of PSSA was 40-55%. The success of sulfonated polystyrene was shown by –SO3H group absorption at 1157.29 cm-1. Etherification of glycerol and benzyl alcohol using PSSA catalyst was conducted at 110 °C for 12 hours. The conversion in producing mono–benzyl ether glycerol was 8.10%, 1,3–dibenzyletherglycerol 2.60%, and dibenzyl ether 9.80%. Therefore, the PSSA can be used as etherification catalyst.
