Judul: Infestasi Lalat (Diptera: Cyclorrapha) pada Tapir Asia (Tapirus indicus) di Taman Margasatwa Ragunan Jakarta Selatan
Abstrak: Informasi mengenai ektoparasit lalat pada tapir asia masih terbatas. Penelitian ini bertujuan menentukan infestasi lalat pada tapir asia. Data diambil dengan diamati morfologi lalat yang hinggap di badan tapir kemudian dihitung jumlahnya pada pagi, siang, dan sore hari. Data dianalisis secara deskriptif. Tingkat infestasi lalat dibedakan menjadi 3 yaitu tingkat rendah (1 sampai 5 ekor lalat), tingkat sedang (6 sampai 10 ekor lalat), dan tingkat tinggi (lebih dari 10 ekor lalat) berdasarkan rata-rata jumlah populasi lalat. Hasil pengamatan didapatkan 2 famili lalat yaitu Muscidae dan Calliphoridae. Tingkat infestasi Muscidae pada kedua tapir ada yang tinggi, sedang, hingga rendah sedangkan infestasi Calliphoridae adalah rendah. Enrichment area umumnya tidak memengaruhi infestasi lalat. Lalat yang hinggap pada tapir mengganggu tapir seperti hinggap di sekitar mulut dan di sekitar mata yang menyebabkan tapir tidak tenang saat beristirahat.

Judul: Infestation of Fly (Diptera: Cyclorrapha) Ectoparasite on Buffalo (Bubalus Bubalis) in Ragunan Wildlife Park, South Jakarta
Abstrak: Kerbau (Bubalus bubalis) merupakan ternak ruminansia besar yang penting bagi masyarakat Indonesia. Ektoparasit lalat menjadi salah satu penyebab masalah kesehatan pada kerbau selain mengganggu kenyamanan hidup ternak. Penelitian ini bertujuan untuk mengetahui jumlah infestasi ektoparasit lalat dan faktor-faktor aktivitas inang (host) berupa waktu aktivitas, berteduh, dan berkubang yang berhubungan dengan jumlah infestasi ektoparasit lalat pada kerbau. Pengamatan dilakukan terhadap tiga ekor kerbau jantan pada tiga waktu aktivitas, yaitu pagi (06.00-07.00 WIB), siang (11.00-12.00 WIB), dan sore hari (16.00-17.00 WIB), dan di saat yang bersamaan diamati juga apakah kerbau sedang berteduh atau berkubang. Pengamatan ektoparasit lalat pada kerbau dilakukan setiap hari, selama 14 hari, secara eye-catching dengan menggunakan alat bantu teropong. Penghitungan ektoparasit lalat pada masing- masing waktu dilakukan sebanyak tiga kali (ulangan). Hasil penelitian menunjukkan bahwa infestasi lalat pada kerbau didominasi oleh lalat Muscidae sebanyak 92,4% dan sisanya lalat Calliphoridae sebanyak 7,6%. Tingkat infestasi ektoparasit lalat lebih tinggi pada aktivitas di siang hari (47,5%) dibandingkan pada pada (32,2%) dan sore hari (20,3%). Sementara itu, aktivitas berteduh dan berkubang dapat mengurangi jumlah infestasi ektoparasit lalat pada kerbau., Buffalo (Bubalus bubalis) is a large ruminant livestock that is important to the people of Indonesia. Fly ectoparasites are one of the causes of health problems in buffalo besides that can interfere with the comfort of livestock life. This study aimed to determine the number of fly ectoparasite infestation in buffalo and the association of host activities with the infestation. Three male buffaloes in Ragunan Wildlife Park, South Jakarta were observed in three activity times, namely in the morning (06.00-07.00 WIB), in the afternoon (11.00-12.00 WIB), and in the evening (16.00-17.00 WIB); and at the same time, it was also observed whether the buffalo was taking shelter or wallowing. The infestation of fly ectoparasites in buffalo was observed everyday during 14 days in an eye-catching manner using binoculars. The number of fly ectoparasites was counted three times of each time (as repeatation). The results showed that flies in buffalo was dominated by Muscidae flies (92,4%) and the other was Calliphoridae flies (7,6%). The rate of fly ectoparasite infestation was higher during the afternoon activity (47,5%) compared to the morning (32.2%) and the evening (20,3%) activities. Meanwhile, shelter and wallowing activities could reduce the number of fly ectoparasite infestations in buffalo.

Judul: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
