Judul: Kajian Kesesuaian Wisata Arung Gelombang di Pantai Citepus aPalabuhanratu, Jawa Barat.
Abstrak: Arung Gelombang or sea rafting is one of coastal tourism that unique, challenging and found in Citepus Beach. Different with rafting conducted in rivers,Arung Gelombang done at sea by wading waves shore. Arung Gelombang still new in Indonesia and there only view one of them in Citepus Beach. Result, show the main indicators for the suitability of Arung Gelombang tourisms are currents, waves, wind, beach structure and dangerous biota. Based on the Index Calculation Arung Gelombang in Citepus has 60% value. This is categorize S2, suitable. Based on coastal landmass 3,8 ha, so carrying capacity in Arung Gelombang is 20 people per day. Factor potential danger in Arung Gelombang are wave, current, wind, dangerous biota and equipment of Arung Gelombang. Level of risks in Arung Gelombang activity in Citepus has varied from low to middle risk;being that produces management option, accept tolerable to reduce risk.

Judul: Identifikasi Fenomena Arus Rabak (Rip Current) Di Kawasan Wisata Pantai Teluk Palabuhanratu, Sukabumi Jawa Barat.
Abstrak: Setiap tahun sering terjadi kecelakaan di kawasan wisata pantai Teluk Palabuhan yang menyebabkan terjadinya kematian wisatawan. Hal ini disebabkan kurangnya informasi mengenai bahaya di kawasan wisata terutama arus rabak. Arus rabak merupakan arus yang bergerak dari pantai menuju laut lepas. Penelitian ini bertujuan mengidentifikasi lokasi, ciri, dan mekanisme arus rabak di kawasan wisata pantai Teluk Palabuhanratu. Arus rabak diidentifikasi melalui analisis data angin, batimetri, gelombang, pasang surut, data statistik korban tenggelam dan foto udara. Angin di Teluk Palabuhanratu dominan berhembus dari arah tenggara. Analisis data batimetri menunjukan karakteristik batimetri dan morfologi di Teluk Palabuhanratu berperan dalam pembentukan arus rabak. Selain itu, karakteristik gelombang di beberapa kawasan wisata Teluk Palabuhanratu memiliki arah rambatan gelombang berkisar dari 0.789° hingga 20.59° yang mendukung proses terbentuknya arus rabak. Berdasarkan analisis pasang surut pula terdapat indikasi akumulasi massa air di sekitar barat dan timur Tempat Pelelangan Ikan (TPI) Palabuhanratu. Analisis foto udara menunjukan adanya indikasi arus rabak di Pantai Kebon Kelapa, Pantai Citepus, Pantai Karanghawu dan Pantai Loji. Arus rabak di kawasan wisata Teluk Palabuhanratu dapat ditandai dengan adanya perairan tenang diantara gelombang pecah. Korban tenggelam paling banyak di Teluk Palabuhanratu terjadi pada kondisi surut.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol
