Abstrak: Products resulting from the fisheries sector is a good source of animal protein to meet the Indonesian people’s needs of nutritional and health. Some products that have a high protein value are shrimp and fish. The need for ease of getting farmed shrimp and fish in a pond increased, also include the harvesting results. Problems faced in fisheries harvesting is too much needed for resources and still lack of harvesting knowledge and skills. One way to minimize these problems is the use of mechanical harvester in harvesting pond. Another problems is that yields are still experiencing disability and high mortality rate. Design approach that taken are functional and structural design approach. From the results of the design will be carried out modeling and functional testing. Functional design is the design that has aspects related to the function and usefulness of each constituent element model of the commodities to be processed. Making models were created to test the success of harvesting systems that work in semi-continuous by vacuum suction mechanism. Because the model harvester shrimp / fish designed aiming to produce a work harvesting semi-continuous by vacuum suction mechanism. Measurements made in the form of rate water, time and speed of shrimp / fish down from the suction tank to the harvesting tank, the ratio number of the shrimp / fish in harvesting tank with shrimp / fish that are still left in the suction tank and pass rates of shrimp / fish alive. From the results obtained it can be seen the amount of shrimp that fell from suction tank to harvesting tank will vary for each time harvesting. The number of commodities that fall will be less and it could be more, depending on the time of harvesting. And the length of harvesting will make this harvester run semi-continuous.

Abstrak: Shrimp is an important commodity for Indonesia, both in domestic and international markets. That quality is influenced by several factors including the harvesting process. So far, the harvesting process for fishery commodities in Indonesia is still using the traditional way. This research aims to design a vacuum-type shrimp harvester to improve the efficiency and effectiveness of farming productivity. So that the quality of shrimp harvested can be maintained high. Stages of this research starts from the problems identification, functional analysis, structural analysis, prototyping, and functional test. This design uses a vacuum system that is applied starting from the inlet channel, tanks, to the outlet channel. By using centrifugal water pump power, commodities in pond are inhaled and trapped in the tank without passing through the impeller. In addition, this design also uses a vacuum pump to maintain pressure in the system. It aims to solve the undetected leaks on the system. From the data obtained, the highest flow rate could reach 5.27 l/s with suction speed of 0.65 m/s, while the lowest flow rate is 4.75 l/s with suction speed of 0.59 m/s. Commodity that can be inhaled by this prototype is shrimp that has burst speed ranging in average of its suction speed, ie 0.61 m/s. It needs the next research to make the other harvesting mechanism to avoid the undetected leaks on the system

Judul: Profil Leukosit Anjing Beagle Setelah Pemberian Obat Anti Caplak Afoxolaner Lima Kali Dosis.
Abstrak: Penelitian ini bertujuan mengetahui profil leukosit anjing beagle setelah pemberian obat anti caplak afoxolaner dengan dosis 1 dan 5 kali dari dosis yang dianjurkan. Penelitian ini menggunakan enam ekor anjing ras beagle yang dibagi menjadi dua kelompok, yaitu kelompok dosis satu kali dan kelompok dosis lima kali. Masing-masing kelompok terdiri atas tiga ekor anjing. Kelompok dosis satu kali diberi afoxolaner dengan dosis 6,3 mg/kg BB, sedangkan kelompok dosis lima kali diberi afoxolaner dengan dosis 31,5 mg/kg BB. Masing-masing perlakuan diberikan sediaan afoxolaner secara per oral dengan frekuensi tiga kali selama 2 bulan, yakni pada hari ke 1, 28, dan 56. Sediaan darah diperiksa dengan alat Hematology Analyzer (Celltac Alpha® type MEK 6450K produksi Nihon Kohden) berupa parameter (leukosit, limfosit, dan granulosit). Selanjutnya data dianalisis menggunakan program Statistical Products and Solution Services version 25 (SPSS V.25). Hasil penelitian menunjukkan bahwa terdapat kenaikan atau penurunan beberapa nilai parameter. Namun, secara statistik menunjukkan tidak adanya perbedaan yang signifikan dari nilai rata-rata semua parameter antar ke 2 kelompok perlakuan. Hal tersebut menandakan pemberian sediaan afoxolaner tidak mempengaruhi faal leukosit anjing sampai lima kali dosis.
