Judul: The daily behavior of wild domestic cats (Felis domesticus) and its correlation to hair colour patterns
Abstrak: Kucing domestik (Felis domesticus) merupakan salah satu mamalia yang hidup berdampingan dengan manusia. Mengacu dari penelitian terdahulu, perilaku kucing memiliki korelasi dengan pola warna rambutnya. Penelitian ini bertujuan mempelajari hubungan antara tipe pola warna rambut dengan perilaku harian kucing domestik liar. Sebanyak delapan kucing domestik liar betina yang berada di dalam area kampus IPB University digunakan dalam penelitian ini. Pengambilan data dilakukan menggunakan metode Focal Animal Sampling untuk mencatat frekuensi perilaku satu individu berdasarkan durasi waktu tertentu. Perilaku yang diamati dibagi dalam tiga kategori yaitu, perilaku afiliatif, pertemuan negatif, dan pemeliharaan diri. Hasil analisis menunjukkan ada keterkaitan antara pola warna rambut dengan perilaku afiliatif. Namun, tidak ada keterkaitan antara pola warna rambut dengan perilaku pertemuan negatif dan perilaku pemeliharaan diri. Hasil tersebut menunjukkan pola warna rambut yang berbeda menghasilkan perilaku afiliatif yang berbeda. Pada kategori perilaku pertemuan negatif dan pemeliharaan diri, pengaruh pola warna rambut tidak berbeda nyata. Kata kunci: belang dua warna, belang tiga warna, focal animal sampling, pola bergaris, pola satu warna, The domestic cat (Felis domesticus) is small mammal that lives alongside humans. Many studies report domestic cats’ behavior correlates with their hair colour patterns. This study aimed to analyse the correlation between various hair colour patterns and wild domestic cats’ daily behavior. As many as eight female wild domestic cats in the IPB University campus were used as objects in this study. Data collection was carried out using the Focal Animal Sampling method to record the frequency of one individual's behavior based on a determined duration of time. The observed daily behavior divided into affiliative, negative encounters, and self-maintenance. Thr results of the analysis obtained show that there’s a correlation between hair colour patterns and affiliative behavior. However, there is no correlation between hair colour patterns, negative encounter behavior, and self-maintenance behavior. These indicate that different hair colour patterns produce different affiliative behaviors. Meanwhile, the effect of the hair colour pattern was insignificant in the category of negative encounter behavior and self-maintenance.

Abstrak: Tamanu oil is one of biosolar substituter as diesel engine fuel. High viscosity of tamanu oil becomes main obstacle in direct using of tamanu oil as diesel engine fuel. Heater element is made to decrease tamanu oil viscosity. Heater element is benefitted high temperature of diesel engine exhaust gas as reheating source. Optimum temperature which is needed to reduce tamanu oil viscosity of 3-5 cSt is 110 Celcius degree (biosolar viscosity of 30oC is 5-7 cSt). IV design of element heater has optimum tamanu oil reheating. There are four kind of tamanu oil that has different treatment. degumming neutralization (N4) tamanu oil has best quality with the lowest viscosity of 30cSt in 30oC. Tamanu oil (N4) usage as fuel occur reduction power of 12.26 %, torsion of 9.59 %, power maximum of diesel engine is 5.39 kW and maximum torsion of 123.74 Nm. Maximum power of diesel engine using biosolar is 5.99 kW and maximum torsion of 144.53 Nm. But then, tamanu oil can replace biosolar (fossil energy), without made as biodiesel first and mixed with biosolar.
