Judul: Ragam Jenis Kutu pada Ayam Bukan Ras di Pasar Tradisional Kota Bogor
Abstrak: Domestic chickens has high economic value because it can be used as a chicken layer and broiler. Lice was one of the ectoparasites that can attack domestic chickens. This study was conducted to determine the diversity and distribution of lice on domestic chickens so that it can be controlled properly. Lices were obtained from 42 domestic chickens at several markets in the area of Bogor, such as Gunung Batu market, Anyar market, Bogor market and Warung Jambu market. Lices were collected from several regions of chicken’s body, such as head to neck, back, breast to feet, wings, and tail. Lice samples were put into the container which has already contained 70% alcohol and identified. The results showed that the prevalence of lice infestation at traditional market was 50%. Lice species discovered were Menopon gallinae (77.14%), Lipeurus caponis (20.57%), and Goniodes dissimilis (2.29%). This study was dominated by Menopon gallinae with the largest distribution in the breast to feet region (97.39%).

Judul: Overview of Broiler Chicken Slaughtering Result Sold at Traditional Markets in Bogor
Abstrak: Penelitian ini bertujuan untuk mendeskripsikan kesempurnaan proses penyembelihan ayam broiler yang dijual di pasar tradisional di Kota Bogor. Sebanyak 475 sampel dibeli dari 95 pedagang yang berada di dalam dan di luar kios. Sampel dipreparir menggunakan alat bedah minor untuk mengidentifikasi saluran trakea, esopagus, dan kedua arteri carotis interna. Jumlah penyimpangan penyembelihan yang terjadi sebanyak 361 sampel (76%). Penyimpangan penyembelihan yang terdapat di dalam kios sebesar 39%, sedangkan penyimpangan yang terjadi di luar kios sebesar 37%. Hasil yang diperoleh menunjukkan buruknya proses penyembelihan. Penelitian ini diharapkan dapat memberikan informasi kepada pengambil kebijakan dan pengawas terkait keamanan dan kelayakan pangan tentang teknik penyembelihan yang baik dan benar pada ayam broiler.

Judul: Numerical modeling of the hydrodynamics of standing wave and scouring in front of impermeable breakwater with different steepnesses
Abstrak: The aim of this paper is to numerically study the effects of breakwater steepness on the hydrodynamics of standing wave and scouring process in front of impermeable breakwaters. A two-dimensional hydrodynamics model based on the Reynolds Averaged Navier–Stokes (RANS) equations and the Volume of Fluid (VOF) method was developed and then combined with an empirical sediment transport model. Comparisons with an analytical solution and experimental data showed the present model is very accurate in predicting the near bottom velocity and capable of simulating the scour/deposition patterns consistent with experimental data. It was found that the additional terms of bottom shear stress in the momentum equations are necessary to produce a physical scouring pattern. Different breakwater steepnesses produce different characteristics of standing wave, the steady streaming system, and scouring pattern in front of the breakwaters, which also affects the correlations between them. An additional analysis of the turbulence field parameters and the sediment transport rate was also performed. All these important information will be presented in details in this paper and can be worthwhile for designing the breakwater in coastal areas.
