Judul: Kajian Teknik Penyimpanan dan Pengemasan Buah Stroberi (Fragaria chiloensis L.) Selama Transportasi
Abstrak: Strawberry is one of the horticultural commodity that has a great potential to be developed commercially. Packaging is the most important method to keep strawberry still maintained in the best quality. Filler material that will be used to package the strawberry was studied in this research to maintain the fruits quality during transportation and storage. Oso grande strawberry cultivar is being used that have characteristics such as: very large size, dense fruit, the texture in the middle of fruit looks like the foam, and high yields. During transportation and storage the packages produce faces numerous hazards, these may be mechanical, environmental, or biological. Mechanical hazards can be defined as those caused by impact, vibration,compression and puncturing. This research studied how interaction the filler with fruits and kinds of compiling strawberry to keep the quality of strawberry fruits during simulation transportation. The purpose of this research are to determine the filling material quality that can maintain the quality of strawberry and to research the effect of mechanical damage on strawberry packaging filler material also to determine the effect of mechanical damage on strawberry. After the packaging, the strawberry fruits do simulation transportation with vibration table during 2 hours with the amplitude 3.63 cm and frekuensi 3.12 Hz. Then the strawberry fruits have storage at 10oC. The test method that being used are biological and mechanical damage testing, fruit weight loss, fruit hardness, and total solids that being dissolved. Fruit mechanical damage can be seen from the number of bruises along the outer side of strawberry fruit, then for biological damage can bee seen from white spotted that seems like fungi that come from strawberry fruit. Fruit hardness or sugar content inside the strawberry can be tested on upper side, middle side and bottom side of the strawberry. The results from the experiment can be concluded that by using styrofoam as material packaging with a horizontal position can maintain the quality of strawberry fruit rather than the other method.

Abstrak: Packaging starfruit (Averrhoa carambola L) becomes a critical factor in maintaining the physical quality of fruit due to vibration during transportation. The objective of this research was to asses the endurance of physical quality parameters of its fruit, such as mechanical damage, hardness, weight losses, and total solid soluble. The first treatment is used sliced filler paper, wood shavings, and sawdust for the filler material in the packs. The second treatment is arranged the starfruit position in packaging by using 2 different methods, namely, vertical and horizontal methods. The result has shown the starfruit which arranged horizontally and packaged with the sliced filler paper is the suitable treatment for packaging. After transportation simulation, the treatment showed 2% of mechanical damage, 0.555 Kgf of hardness and 7% obrix of total solid soluble. At the 8th day, showed 86% of mechanical damage, 0.426 Kgf of hardness, 3.76% of weight lose and 8.3% obrix of total solid soluble. The horizontal position of packaging can reduce the vibration better than the vertical one.

Judul: Babesiosis pada kuda
Abstrak: Babesiosis pada kuda adalah penyakit menular yang di- sebabkan oleh Babesia caballi dan Babesia equi, yaitu pa- rasit protozoa perusak sel darah yang termasuk dalam genus Babesia. B. equi diduga oleh beberapa ahli termasuk dalam genus Theileria. Karena itu klasifikasi genus Babesia di- bicarakan dan siklus hidup B. caballi dan B. equi diulas. Kuda pada semua umur dapat terserang oleh dua parasite tersebut di atas. Tetapi kuda-kuda yang sudah dewasa (tua) lebih rentan jika dibandingkan dengan kuda-kuda yang masih muda. Kasus-kasus yang paling sering dijumpai adalah kasus-kasus yang bersifat akut walaupun kasus-kasus yang bersifat perakut, subakut dan kronik kadang-kadang terlihat. Serangan oleh parasit Babesia biasanya menyebabkan kerusаkan sel darah merah yang hebat sehingga kuda-kuda yang terserang menderita anemia hebat yang dapat menyebabkan kematian bila tidak segera diobati. Untuk mengatasi hal tersebut perlu dilakukan diagnosis yang tepat dan sedini mungkin. Diagnosis dapat dilakukan dengan cara memeriksa gejala-gejala klinik, preparat ulas darah, inokulasi hewan lain dan dengan mengadakan pemeriksaan secara serologik. Gejala-gejala klinik babesiosis pada kuda yang bersifat akut yang paling sering terlihat, ialah : nafsu makan menurun/hilang, lesu, bulu suram dan tidak mau bergerak. Kuda yang dilepaskan di padang rumput akan mengasingkan diri dan jalan sempoyongan. Faeces yang keluar berwarna cok- lat gelap, diselaputi lendir yang berwarna kekuningan dan urimenya berwarna merah tua. Temperatur tubuh meningkat menjadi 39.5 - 41°C dan pulsus meningkat. Terlihat dispnoe, perdarahan petechi pada mukosa membrana nictitans dan conjunctiva yang lebih pucat dari normal dan juga icteris. Kasus-kasus yang bersifat subakut gejala-gejalanya lebih ringan, tetapi bila tidak segera diobati maka gejala- gejala tersebut secara cepat menjadi hebat. Persendian lutut dan persendian gelang puyuh membengkak dan padanya ter- lihat oedema. Pada abdomen, dada dan kepala juga dapat di- temukan oedema. Gejala-gejala klinik yang terlihat pada kasus kronik adalah penurunan kondisi tubuh kuda secara progresif walaupun diberi makan yang banyak. Perubahan temperatur tidak jelas, nafsu makan berubah-ubah, icterus tidak jelas dan anemia mungkin hanya dapat dideteksi dengan menghitung sel darah merah dan kadar hematocrit…dst
