Judul: Sintesis Nitril Lemak Jenuh Dan Uji Kinerjanya Sebagai Inhibitor Korosi Tembaga
Abstrak: Nitril lemak jenuh merupakan senyawa organik yang berpotensi sebagai inhibitor korosi. Nitril lemak jenuh dapat disintesis dari asam lemak jenuh yang banyak terdapat di alam. Metode reaksi satu-wadah berhasil mengonversi asam lemak menjadi nitril lemak. Keberhasilan sintesis dibuktikan dengan pencirian berdasarkan kromatogram lapis tipis dan spektrofotometer inframerah transformasi Fourier. Rendemen sintesis miristonitril, palmitonitril, dan stearonitril ialah 52.25%, 46.58%, dan 51.22%. Kinerja inhibitor korosi diuji pada logam tembaga. Efektivitas inhibitor korosi nitril lemak jenuh lebih tinggi daripada asam lemak jenuh. Efektivitas inhibitor optimum terjadi pada konsentrasi 100 ppm dalam medium NaCl 1% kondisi netral.

Judul: Sintesis Tetrazola Berbasis Asam Lemak dan Aplikasinya sebagai Inhibitor Korosi
Abstrak: Tetrazola merupakan senyawa yang banyak diaplikasikan pada berbagai bidang, salah satunya sebagai inhibitor korosi. Tetrazola dapat dibuat melalui siklisasi formal [2+3] dari senyawa azida dan nitril. Tujuan dari penelitian ini adalah memperoleh senyawa tetrazola berbasis asam oleat dan mengetahui kinerjanya sebagai inhibitor korosi. Sintesis dilakukan dalam dua tahap: (1) pembentukan nitril melalui reaksi asam lemak dengan urea (2) konversi nitril menjadi senyawa tetrazola dengan penambahan natrium azida dan ZnCl2 sebagai katalis. Hasil sintesis menunjukkan bahwa rendemen menurun dengan adanya ikatan rangkap, sebaliknya %EI meningkat dengan bertambahnya ikatan rangkap pada rantai alkil tetrazola.

Judul: Teknik penangkaran dan aktivitas harian mambruk victoria (Goura victoria Fraser, 1844) di Mega Bird And Orchid Farm, Bogor Jawa Barat
Abstrak: Victoria crowned pigeon (Goura victoria Fraser, 1844) is one of endemic bird species in Papua, which population had decreased in the natural habitat due to hunting activities. Ex-situ conservation through captive breeding/captivity is an alternative to sustain the bird population. Observation on it’s daily activities in captivity was expected to result in good captivity technique which would enable the preservation of it’s population and restocking of the species in their natural habitat. This research was aimed to study the captivity techniques, identify factors of success, and observe the daily activities of the victoria crowned pigeon. The research was conducted in Mega Bird and Orchid Farm (MBOF) located in Desa Cijujung Tengah, Bogor, West Java on June – July 2011. Instruments used include stationery, stopwatch, camera, interview guide, dry-wet thermometer, and measuring tape. Object of the research was victoria crowned pigeon in MBOF. Data taken during the research included the captivity technique and daily activities of victoria crowned pigeon in MBOF. Data collection methods employed in the research for the captivity technique were direct observation, literature study, and interview, as for the aspects of the daily activities was one-zero sampling method. The cage was classified a permanent maintenance cage with 40 m × 25 m × 5 m dimensions which made from wall, iron with + 5 cm in diameter, and ram wire for roof. Facilities provided in the cage were among other perch place, eating and drinking place, nesting place, and pond. The cage was regularly cleaned twice a day and sprayed with disinfectant once a month. Temperature in the cage was between 25 – 32oC with moist air ranges between 57 – 78%. The type of diseases suffered by the victoria crowned pigeon were CRD (Chronic Respiratory Disease), intestinal worms, and leg swelling. Technique of pairing, laying or hatchery setting, and native enlargement was naturally done by victoria crowned pigeon’s parent. Factors which support the success of captive breeding management in MBOF were (a) location of the cage which away far from noise and human disturbance; (b) the hygiene, safety, and care of the cage; (c) the feeding routine given every morning and evening; (d) provision of medication and vitamins on regular basis to maintain good health and prevent disease from attacking the birds in captivity; and (e) maintenance of genetic purity and avoidance of inbreeding occurenes. Type of behavior that can be used to distinguish the sex of the victoria crowned pigeon was dancing behaviour performed by male individuals.
