Judul: Morphological Characteristics of the Skull of Malayan Tapir (Tapirus indicus)
Abstrak: The Malayan Tapir ( Tapirus indicus ) is an iconic herbivorous mammal in Southeast Asia, characterized by having a proboscis, a distinctive color and an important ecological role. The status of this animal according to the IUCN is a threatened species. This research aims to study the morphology of the skull of Malayan tapir, which is associated with feeding behavior. This research used a descriptive method, comparing the skulls of horses (genus Equus) and Brazilian tapirs (Tapirus terrestris). Tapir relatively has rounder shaped skull, shorter and thicker os nasale, deeper fossa masseterica, and wider apertura cavum nasi than horse. Other differences are the eye orbit is open while in horse is closed. Tapirs exhibit ortal masticatory movements, driven by brachydont teeth with bilophodont characteristics, which are very different from horse hypsodont teeth designed for lateral movement. The proboscis of the tapir is unique has a muscular structure than in horse, including the nasal bones, that is shorter and thicker than that of horses. These differences have influenced the feeding behaviour of tapir species and for tapir nocturnal activity. This research contributes to broader conservation efforts aimed at conserving tapir populations and their habitats., Tapir/Malayan tapir (Tapirus indicus) merupakan mamalia herbivora ikonik di Asia Tenggara, mempunyai ciri khas yaitu mempunyai belalai, warnanya yang khas dan mempunyai peran ekologis yang penting. Status hewan ini menurut IUCN adalah spesies terancam. Penelitian ini bertujuan untuk mempelajari morfologi tengkorak tapir, yang dikaitkan dengan perilaku makan. Penelitian ini menggunakan metode deskriptif, membandingkan dengan tengkorak kuda (genus Equus) dan tapir Brazil (Tapirus terrestris). Tapir mempunyai bentuk tengkorak relative lebih bulat, os nasale tebal dan pendek, fossa masseterica lebih dalam, apertura cavum nasi lebih luas dibandingkan pada kuda. Perbedaan lain adalah orbita mata pada tapir terbuka sedangkan pada kuda tertutup. Tapir mempunyai gigi brachydont dengan karakteristik bilophodont untuk mendukung gerakan mastikasi orthal. Struktur ini menunjang adaptasi perilaku makan dan aktivitas nokturnal tapir. Penelitian ini berkontribusi pada upaya konservasi untuk melestarikan populasi tapir dan habitatnya.

Judul: Keberhasilan Reproduksi Tapir Asia (Tapirus indicus) Di Kebun Binatang Di Dunia
Abstrak: The aim of this study was to analyze reproduction datas of malayan Tapir (Tapirus indicus) which spread in the zoos world wide and recorded in International Malayan Tapir Studbook which were marriage season pattern, amount of birth, offspring survival, and life expectation. Tapirs recorded in International Malayan Tapir Studbook until July 2009 were 921 heads, with tapirs bornt in conservation were 540 heads. Cubs were born all year round without following certain season (nonseasonal). The result showed that tapir has low dead give-birth level (stillbirth 0,0-7,93%) and high give-birth potention (1 head every 2 years) so the population can be increased by good management practices.

Judul: The Isolation of Silver (Ag) from Fixer Sludge with Electrolysis methode
Abstrak: with the variations concentration, electrode of carbon, and voltages. The aim of research are looking for the easiest and eficient electrolysis. Among of 272.79 ppm of silver (impurities) could be produced from electrolysis fixer which used 300 times maintain the film. For 400, 500, and 600 times electrolysis were produced recently 49.42, 137.04, and 55.22 ppm. Futhermore, it was increased to 220.00 ppm from 700 times. These were possible because of density the solutions. From the electrode of carbon, 68.2222 g Ag (impurities) could be processed from size 14 cm x 3 cm x 3 cm. The next results 41.2050 g and 43.7559 g from the sizes 16 cm x 3 cm x 3 cm and 18 cm x 3 cm x 3 cm. The reasoned of this part any faster reaction on the most litle electrode. By the way, from voltages variation, the processed showed that 47.4575 g of Ag (impurities) could be produced from 11 volt. It’s caused the bigest voltages are also the bigest kinetics power on the reactions. Sampel and product were analized by AAS. Consentration has potential to be indicator, because of the used 700 times was given trend high Ag (impurities) became increase optimally at 11 volt, and much sediment that is 47.4575 g. The best rendemen is 13.33%. The other finding is that the strength of the time and the voltages strongly enfluence the electrolysis shown by the bigger result on F(calculation) than that of the F(table).
