Abstrak: Degradation of vitamin A is affected by light. The objective of this research is making an analysis correlation between oxidative parameter in oil (peroxide and free fatty acid value) and vitamin A value. Palm oil fortified vitamin A with different initial peroxide value (0.00, 3.99, and 8.99 meq O2 active/kg oil) is used as samples. Photostability in oil is measured by keep the samples at different light exposure (5000, 10000, and 15000 lux). The result of this research showed that free faty acid is not a good parameter to decide shelf life of oil because its production is not affected by light. Shelf life of palm oil fortified vitamin A are 110.11 hours, 44.27 hours, and 16.34 hours for samples with initial peroxide value 0, 3.99, and 8.99 meq O2 active/kg oil. The most compatible palm oil-fortified vitamin A are palm oil with initial peroxide value 0.00 and 3.99 meq O2 active/kg oil.

Judul: Kinetika Oksidasi Termal Minyak Goreng Sawit Curah dengan Fortifikasi Vitamin A
Abstrak: Vitamin A is one of an essential vitamin for human body. However, the deficiency of vitamin A is still in the spotlight not only in Indonesia but also in the world. Fortification of Vitamin A into cooking oil is one of solution to resolve this problem. In the other hand, the stability of vitamin A is an important thing to be studied. There are factors that influence the stability of vitamin A such as heat and oxygen. In this present study, the cooking oil that will be fortified has a difference of initial peroxide number i.e. 0.00; 3.99; and 8.99 meq active O2/kg oil. Besides that, the cooking oil that used has differences of temperature storage i.e. 60; 75; and 90°C. The objective of this study was to obtaining the model of thermal oxidation kinetics of cooking oil fortified with vitamin A levels are three types of different initial peroxide. The parameter that be used in this kinetic-study were the peroxide number, free fatty acid level using titrimetry analysis, and the level of vitamin A using HPLC. The result show that the formation of peroxide number and free fatty acid followed the zero order meanwhile the degradation of vitamin A followed the order 1. The reaction rate constant (k) and the energy of activation were calculated by using arrhenius equation. According to the result, the k-value from all of the parameter tends to increase by increasing of the time. The value of activation energy for each oxidation parameter were in ranges 44-64 kJ / mol for peroxide number, 48-64 kJ / mol for free fatty acid and 62-83 kJ / mol for degradation of vitamin A. According to the activation value that obtained, the fortified cooking oil with initial peroxide number 0.00 meq active O2/kg of oil is the most sensitive oil sample to the temperature in comparison with the other oil sample.

Judul: Beberapa aspek anatomi alat sirkulasi ruang dada kancil
Abstrak: Telah dilakukan penelitian dengan menggunakan 10 ekor kancil dewasa jantan dan betina dengan tujuan untuk menge- tahui beberapa aspek anatomi alat sirkulasi di dalam ruang dada, meliputi jantung, pembuluh darah yang keluar dan ma- suk jantung serta ukuran-ukuran jantung. Kancil merupakan ruminansia terkecil di dunia, hidup di daerah tropika India, Thailand, Malaysia dan Indonesia bagian barat. Hewan ini dilindungi dan mempunyai prospek yang baik untuk hewan penelitian maupun dibudidayakan. Hasil penelitian menunjukkan bahwa berat jantung rаta-rata adalah 0.69% dari berat rata-rata kancil. Dan ini mirip pada jantung kuda dan anjing. Bentuk jantung lonjong seperti halnya ruminansia. Demikian pula letaknya di dalam ruang dada seperti pada ruminansia dengan adanya Ligamentum sternopericardiacum. Di dalam ventrikel kanan membersit sebuah Musculus (M.) papillaris dari dindingnya dan tiga sampai empat Musculi (Mm.) papillares dari Septum interventriculare. Hanya dua buah Mm. papillares yang berukuran besar dibersitkan dari dinding ventrikel kiri. Percabangan Arteri (A.) coronaria sinistra lebih dominan dari pada A. coronaria dextra. Sedangkan A. sub clavia sinistra dicabangkan langsung dari aorta di dorso- caudal pembersitan Truncus (Tr.) brachiocephalicus…
