Judul: Jumlah leukosit, differensiasi leukosit, dan indeks stress Luak Jawa (Paradoxurus hermaphroditus)
Abstrak: Common palm civets (Paradoxurus hermaphroditus) have the potential to be the best coffee producing animals in Indonesia. Therefore, their health status is very important. Health status of common palm civets can be observed through of their white blood value. This study was aimed to discribe the leukocyte count, it’s differentiation, and stress index of 8 Java common palm civets, 4 males and females. The experiment had done at laboratory of Physiology, department Anatomy, Physiology, and Pharmacology, Faculty of Veterinary Medicine, Bogor Agricultural University during 7 weeks, sampling was done at weeks 1st, 5th, 6th, and 7th, then sample were analyzed for their leukocytes, their differentiation, and their stress index. The average leukocyte count of male and females common palm civets was (3.33±0.86)x103/mm3 and (2.83±0.70)x103/mm3, neutrophil amount of male and female Java common palm civets was (1.01±0.47)x103/mm3 and (0.68±0.30)x103/mm3, basophil did not find at leukocyte differentiation of common palm civets, eosinophil amount of male and female Java common palm civets was (0.16±0.18)x103/mm3 and (0.04±0.05)x103/mm3, lymphocyte amount of male and female Java common palm civets was (2.06±0.42)x103/mm3 and (2.05±0.59)x103/mm3, monocyte amount of male and female Java common palm civets was (0.09±0.06)x103/mm3 and (0.06±0.06)x103/mm3, and stress index was (0.49±0.18) and (0.37±0.22). Generally leukocyte count of male Java common palm civet have higher value than it’s female. The mean of leukocyte count of Java common palm civets was under average leukocyte count of Thailand common palm civets.

Judul: Feeding Behavior of the Asian Palm Civet (Paradoxurus hermaphroditus) in MB Coffee Captive Breeding, Cianjur Regency, West Java.
Abstrak: Musang pandan (Paradoxurus hermaphroditus) merupakan satwa yang banyak dipelihara sebagai hewan peliharaan maupun untuk ditangkarkan. Penelitian ini dilakukan untuk mengetahui perilaku makan, preferensi pakan, dan membandingkan preferensi pakan pada kelas umur dan jenis kelamin berbeda. Pengamatan dilakukan pada empat ekor musang pandan jantan dan betina muda pada umur 9 bulan, dan dewasa pada umur 2 tahun di Penangkaran MB Coffee. Metode yang digunakan adalah metode continuous recording yang dilakukan pada pukul 18.00-22.00 WIB selama 22 hari. Pengumpulan data terdiri dari 6 hari pengamatan preliminary dan 16 hari pengamatan. Telah dihasilkan sebanyak 1.487 perilaku makan, terdiri dari perilaku feeding seperti mengendus, memindahkan pakan, memasukkan ke mulut, mengunyah, menelan pakan, minum, dan memotong pakan. Dapat disimpulkan bahwa dari seluruh sampel lokasi makan kesukaan adalah langsung di wadah pakan, dan pakan dengan palatabilitas tertinggi adalah buah pepaya. Berdasarkan penilaian secara skoring didapatkan hasil bahwa kelas umur dan jenis kelamin tidak mempengaruhi keseluruhan preferensi pakan Kata kunci: Musang pandan, preferensi pakan, palatabilitas, The common palm civet (Paradoxurus hermaphroditus) is an animal used in producing civet coffee which is high in taste and expensive. This study was conducted to determine feeding behavior, feed preferences, and compare feed preferences in different age and sex classes. Observations were made on four young male and female palm civets at the age of 9 months, and adults at the age of 2 years in MB Coffee Captive Breeding. The method used is the continuous recording method which is carried out at 18.00-22.00 WIB for 22 days. Data collection consisted of 6 days of preliminary observation and 16 days of observation. As many as 1,487 eating behaviors have been produced, consisting of feeding behaviors such as sniffing, moving feed, putting it into the mouth, chewing, swallowing feed, drinking, and cutting feed. It can be concluded that from all samples the preferred feeding location is directly in the feed container, and the feed with the highest palatability is papaya fruit. Based on the scoring assessment, it was found that age class and sex did not affect the overall feed preference. Keywords: common palm civet, feed preference, palatability

Judul: Sintesis nanopartikel Cu2ZnSnS4 menggunakan teknik hidrotermal
Abstrak: Nanopartikel Cu2ZnSnS4 (CZTS) merupakan semikonduktor yang berpotensi sebagai fotokatalis untuk reaksi fotodegradasi zat pewarna. Semikonduktor ini memiliki sela pita yang jauh lebih kecil dibandingkan dengan semikonduktor TiO2, sehingga memungkinkan dapat berkerja hanya dengan paparan sinar matahari. Nanopartikel Cu2ZnSnS4 telah berhasil disintesis menggunakan teknik hidrotermal dengan suhu 200 oC selama 24 jam. Larutan Cu2ZnSnS4 dinetralkan menggunakan amonium hidroksida dan dialiri gas N2 sebelum proses hidrotermal. Hasil analisis mikroskop elektron pemayaran menunjukkan nanopartikel Cu2ZnSnS4 mengalami aglomerasi karena memiliki ukuran partikel yang besar. Hasil analisis difraktogram sinar-X menunjukkan bahwa Cu2ZnSnS4 yang dihasilkan memiliki struktur kesterit dengan senyawa fase sekunder yang terbentuk adalah CuS, ZnS, dan Cu2SnS3. Hasil uji fotodegradasi menunjukkan bahwa senyawa hasil sintesis memiliki kemampuan degradasi dibawah sinar matahari lebih baik dibandingkan dengan TiO2. Namun, pada paparan sinar UV, TiO2 mendegradasi biru metilena lebih baik daripada senyawa hasil sintesis. Kapasitas adsorbsi terhadap biru metilena sebesar 2.6780 mg/g menunjukkan bahwa senyawa hasil sintesis tidak mampu mengadsorpsi dengan baik, sehingga disimpulkan bahwa hilangnya biru metilena dari larutan disebabkan oleh fotodegradasi, bukan oleh adsorpsi
