Judul: INVENTORY OF PATHOGENS IN CARP Cyprinus carpio IN THE DRAMAGA SILET LAKE FISHING BOGOR
Abstrak: Telaga Silet merupakan salah satu objek wisata di bidang perikanan yang bergerak di usaha pemancingan. Salah satu kendala yang menyebabkan kegiatan tersebut terganggu adalah serangan penyakit. Penyakit yang umumnya terjadi pada budidaya ikan mas dapat disebabkan oleh bakteri, parasit, jamur, dan virus. Penelitian ini bertujuan menginventarisasi patogen penyebab penyakit yang manyebabkan kematian pada usaha pemancingan di Telaga Silet Dramaga. Metode penelitian meliputi pengambilan sampel, pemeriksaan parasit, pemeriksaan cendawan, identifikasi bakteri dan deteksi Koi herpesvirus melalui analisis Polymerase Chain Reaction (PCR), dan histopatologi. Terdapat parasit yang menyerang ikan mas yaitu Argulus sp. yang menyebabkan bercak perdarahan dan kulit luka. Luka akan memicu munculnya pathogen lain seperti cendawan Saprolegnia sp. dan bakteri Aeromonas sp. akibat adanya interaksi antara pathogen satu dengan pathogen lainnya. Tidak terdeteksi KHV pada sampel ikan mas yang diperiksa. Hasil pengamatan histopatologi terdapat perubahan mikroanatomi patologi kerusakan jaringan insang paada bagian lamella primer dan lamella sekunder yaitu nekrosis, hyperplasia, edema, kongesti, dan telangiektasis. Kerusakan jaringan kulit ditemukan peradangan sel dan erosi epitel akibat luka yang disebabkan Argulus sp.

Judul: Pathogen Inventory and Survival of Carp Soaked with the Addition of Post-Transportation Banana Stems
Abstrak: Salah satu hambatan pada kegiatan budidaya ikan mas adalah penyakit yang akan menurunkan produktivitas. Pemancingan Telaga Silet di Dramaga mengalami permasalahan berupa terjadinya kematian pada ikan mas yang ditransportasikan dari Gresik dan Sukabumi. Salah satu upaya yang dapat dilakukan yaitu dengan pemberian cacahan batang pisang ambon. Penelitian ini bertujuan untuk menguji efektivitas penggunaan cacahan batang pisang ambon terhadap kelangsungan hidup ikan mas pascatransportasi di Pemancingan Telaga Silet Dramaga, Bogor. Penelitian ini menggunakan ikan mas dengan bobot rata-rata 3,44±0,4 kg dan panjang rata-rata 46±0,3 cm. Penelitian ini terdiri dari kontrol dan perlakuan cacahan batang pisang ambon berdimensi 2×3 cm dengan dosis 5 g L-1. Perendaman dan pemeliharaan dilakukan selama enam minggu dengan pergantian cacahan batang pisang setiap dua minggu sekali. Hasil penelitian ini menunjukkan bahwa patogen yang ditemukan pada ikan mas pascatransportasi setelah diberikan cacahan batang pisang ambon terdiri dari ektoparasit Argulus sp., cendawan Saprolegnia sp., dan bakteri Aeromonas sp., Aeromonas salmonicida, Pseudomonas, Flavobacterium, dan Bordetella parapertussis., In common carp rearing activities, one of the obstacles can be disease which will reduce the value of its productivity. Silet Lake fishing in Dramaga is experiencing problems in the form of many deaths of carp transported from Gresik and Sukabumi. One effort that can be done is by giving chopped ambon banana stems. This study aims to determine the effectiveness of using chopped ambon banana stems on the survival of post-transport carp in Dramaga Lake Silet Fishing, Bogor. The average carp weight was 3.44 ± 0.4 kg and the average length was 46 ± 0.3 cm. This study consisted of control and treatment chopped ambon banana stems with dimensions of 2×3 cm at a dose of 5 g L-1. Soaking and maintenance were carried out for six weeks with the replacement of chopped banana stems every two weeks. The results of this study showed that the pathogens found in goldfish after transportation after being given chopped Ambon banana stems consisted of the ectoparasites Argulus sp., the fungus Saprolegnia sp., and the bacteria Aeromonas sp., Aeromonas salmonicida, Pseudomonas, Flavobacterium, and Bordetella parapertussis.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
