Judul: Karakter Dominansi dan Perilaku Stereotipe pada Monyet Ekor Panjang (Macaca fascicularis) Sitaan serta Saran-saran Pengelolaannya.
Abstrak: This study is dedicated to support the behavioural management of confiscated dancing monkeys of cynomolgus macaques (Macaca fascicularis) at UPT Pusat Pelayanan Kesehatan Hewan Jakarta province. This management is to improve animal welfare and rehabilitate stereotypical anomaly behaviour. Therefore cages condition and behaviour of 47 confiscated monkeys were observed using instantaneous sampling method. The cages condition include 4 socially stable cages and 2 socially unstable cages. Dominant characteristic is found in both type of cages where at socially unstable cages shows higher frequency of aggressive behaviour. The stereotypical behaviour movement of head left to right (weaving) only found in socially unstable cage. Movement of head front to back (rocking) found in both cages and self-injurious behaviour (SIB) found in socially stable cages. In managing the dynamics and rehabilitate the abnormal behaviour mentioned above, it is found that environmental enrichment is needed. This includes social enrichment, occupational enrichment, physical enrichment, sensory enrichment, and nutrition enrichment. It is hope that these information will be the guideline in managing dominant character of confiscated monkeys and its stereotypical behaviour.

Judul: Behavior of Long Tailed Monkeys (Macaca fascicularis) and Enrichment of Cages at The Ex-situ Captive Breeding Primate Research Center
Abstrak: Monyet ekor panjang (Macaca fascicularis) adalah primata yang memiliki keberhasilan adaptasi tinggi yang dapat dilihat melalui perilaku hariannya. Pengayaan kandang adalah metode buatan yang dapat merepresentasikan habitat aslinya di alam. Salah satu faktor penting keberhasilan dalam konservasi eksitu yaitu pengayaan kandang yang dibuat semirip mungkin dengan keadaan di alam. Penelitian yang dilaksanakan pada bulan Februari – Mei tahun 2021 di Penangkaran Pusat Studi Satwa Primata (PSSP) bertujuan untuk mengidentifikasi perilaku monyet ekor panjang dan mengidentifikasi pengayaan kandang monyet ekor panjang di PSSP. Pengamatan perilaku dilakukan dengan metode scan sampling. Perilaku monyet ekor panjang tertinggi yang dilakukan di PSSP berturut-turut adalah istirahat, menelisik, dan berpindah. Fasilitas kandang yang terdapat dalam kandang PSSP berdasarkan persentase penggunaan tertinggi antara lain rak dinding, rantai, dan lantai. Jenis Fasilitas untuk pengayaan kandang yang perlu ditambahkan adalah rak dinding. Ukuran kandang di penangkaran PSSP dibandingkan dengan standar kandang untuk hewan laboratorium memperlihatkan luasan yang sudah memenuhi standar ukuran kandang., The long-tailed monkey (Macaca fascicularis) is a primate that has high number of adaptation success which that can be seen through its daily behavior. Enrichment of the cage is an artificial method that can represent its natural habitat in nature. One of the important success factors in ex-situ conservation is cage enrichment which is made as close as possible to conditions in nature. The study which was conducted in February – May 2021 at the ex-situ captive breeding primate research center (PSSP) aims to identify the behavior of long-tailed monkeys and identify the enrichment of cages for long-tailed monkeys in PSSP. Behavioral observations were carried out using the scan sampling method. The highest behavior of long-tailed monkeys in PSSP was resting, grooming, and locomotion. The cage facilities contained in the PSSP cage based on the highest percentage of use including wall shelves, chains, and floors. Types of facilities for enrichment of cages that need to be added are wall shelves. The size of the cage in the PSSP captivity compared to the standard cage for laboratory animals shows that the area already meets the standard size of the cage.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
