Judul: Kajian Aspek Pertumbuhan Cumi-cumi (Loligo duvauceli Orbigny 1848) di Perairan Teluk Banten yang Didaratkan di PPN Karangantu, Provinsi Banten
Abstrak: Squid (Loligo duvauceli) is one of dominant catches in water of Banten Bay using dogol (demersal danish seine). High and continously catch on activity brings through reduction on size of squid populations. Therefore, an appropriate and sustainableresource management is needed. One of information required in appropriate management is about growth aspect. Squid sampling was conducted in PPN Karangantu on September-November 2012 every 14 days.Length frequency distribution of male squid ranged between 35-286 mm, while females between 40-280 mm. Through the analysis of growth parameter estimation, can be obtained K value (growth coefficient),L∞ (asymptotic length), and t0 for squid males and females are respectively, K equal to 0,21 and 0,31 per month, L∞ equal to 400.05 and 281.14 mm, with t0 -0,40 and -0,29 months

Judul: Pengelolaan Sumber Daya Cumi-Cumi (Loligo sp Hegner dan Engemann 1968) di Pelabuhan Perikanan Nusantara (PPN) Karangantu, Kabupaten Serang, Provinsi Banten
Abstrak: The main purpose of this research is to estimate the Exploitation Rate and Mortality Rate of squid, the Maximum Sustainable Yield (MSY), the Maximum Economic Yield (MEY), Open Access Yield (OA), and to make the management plan. The methods used in this research are method Production Surplus and Bio-Economy Analysis. Data used in this research are primary data which consists of the data of length and weight of squids, and operational cost of fishing, and secondary data which consists of amount of fish product, and the fishing effort which are taken from PPN Karangantu. The result of the research showed that based on the length of squid (Loligo sp) which catched around the Banten Bay, and which landed to Karangantu National Fishing Harbor (PPN) have been occurred overfishing. This matter can be seen by the result of Exploitation Rate (0.7545) that reached over the optimum exploitation rate. This overfishing caused by fishing mortality that more than natural mortality. This matter can also be seen by the amount of fish product, and the fishing effort in PPN Karangantu that squid (Loligo sp) has been occurred an overfishing by the bio-economic point of view because of the actual data result of effort value has got the more rate result than MSY and MEY effort rate, so the fishing result has decreased and the profit is not optimum.

Judul: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
