Judul: A Study On Potential Renewable Energy From Ocean Waves in Palabuhanratu Bay
Abstrak: One of the sources of energy in the sea that can be utilized in Indonesia is wave energy. This study aims to see the potential of ocean wave energy in Palabuhanratu Bay spatially and temporally using a modeling method with the DELFT 3D application. The data sources used are bathymetry data from BIG, wind data from ECMWF, and wave data from Copernicus. Data processing is done by processing bathymetry and wind data first, which is then entered into the model configuration and then adjusted according to the moonson period and scenario. The sea wave power generator (PLTGL) converter scenario is used to estimate the existing potential using a Point Absorber converter. The wind in Palabuhanratu Bay is included in the category of slow gusts with the highest frequency in the category 2,10 – 3,60 m s-1 with a percentage of 30,5%. The sea waves in Palabuhanratu Bay are categorized into Slight Sea with significant wave heights ranging from 0 - 2 m with an average period of 15 seconds. Based on the model results, the wave energy transport has an energy value of up to 0 - 8 kW m-1 with the highest value occurring in the East Season. Based on these results, the Point Absorber type PLTGL produces electric power in Palabuhanratu Bay with two scenarios, the first scenario is in the inner bay which produces 0.09 MW of power with an average energy per day of 261 W. 2,7 MW with an average energy per day of 7344 W.

Abstrak: Methods to estimate potential fishing ground play an important role in fishing activities. Therefore, the application of appropriate methods and the right location is needed to support the success of fishing. This study aimed to estimate and mapping the potential fishing area in the Palabuhanratu bay and its surroundings. Potential fishing ground was estimated by spatial analysis on waters parameters, which were chemical and physical parameters, such as chlorophyll-a, dissolved oxygen, current, temperature and salinity using hydrodynamic-ecosystem models. Results showed that throughout the year fishing ground are quite dynamic, when West Monsoon (December-February) and Transitional Season 1 (March-May) the high potential fishing ground located around the coast. While in East Monsoon (June-August) and Transitional Season 2 (September-November) almost all area were medium potential fishing ground until high potential fishing ground.

Judul: Infeksi cacing Ascarid pasa anjing dan kucing, serta hubungannya sebagai zoonosis
Abstrak: Ada tiga cacing Ascarid yang didapatkan pada anjing dan kucing, yaitu Toxocara canis pada anjing, Toxocara cati pada kucing dan Toxascaris leonina pada anjing dan kucing. Ketiganya mempunyai habitat di usus kecil (Soulsby, 1982). Manusia dapat bertindak sebagai induk semang paratenik dari kelompok ini, melalui anjing dan kucing yang menderita sebagai sumber infeksi, terutama anak- anak anjing dan anak-anak kucing (Brown, 1975). Dari kelompok Ascarid ini penyebab utama penyakit pada manusia adalah Toxocara canis (Soulsby, 1982). Penyakit pada manusia yang disebabkan oleh kelompok ini dikenal sebagai penyakit 'Visceral Larva Migrans' (Brown, 1975), Toxocariasis (Beaver, 1966). Penularan pada anjing dan kucing, dapat melalui telur infektif (langsung), induk semang paratenik seperti tikus, kecos, cacing Lanah dan lain-lain (tidak langsung), intrauterin, trans-mammary dan secara fecaloral. Pada manusia, penularan terjadi melalui telur infektif yang tertelan. Gejala klinis yang tampak pada anjing dan kucing yang terinfeksi oleh kelompok ini, adalah anjing kurus, pertumbuhan terhambat, gelisah, batuk, respirasi meningkat, keluar cairan dari hidung, muntah yang kadang kadang bercampur dengan cacing, icterus, diare, sakit pada abdomen, perut buncit dan kadang-kadang timbul gejala konvulsi (Kelly, 1977). Pada manusia tanda klinis yang umum terlihat, yaitu batuk, dispnoe disertai demam dan gejala umum lainnya. Kadang-kadang endopthalmitis, retinitis perifer, papilitis, dan konvulsi. Pemeriksaan darah terlihat eosinofilia, leukositosis, hiperglobulinemia dan pemerik saan yang lain memperlihatkan hepatomegali…dst
