Judul: Perilaku Seksual Monyet Ekor Panjang (Macaca Fascicularis) di Makam Kramat Solear, Kabupaten Tangerang
Abstrak: Perilaku seksual merupakan salah satu interaksi antara jantan dewasa dengan betina dewasa yang sedang estrus. Perihal seksual penting peranannya dalam memelihara kelangsungan kelompok. Ada dua macam perilal'U yang terdapat pada setiap individu yaitu petilal'U innole dan leamillg. Peril"ku seksual merupakan salah satu perilaku belajar (/eaming). Penelitian ini untuk mengetahui pola perilaku seksual monyet ekor panjang (M. fascicularis) di Makam Kramat Solear, Kabupaten Tangerang. Pengamatan dila1.'Ukan dengan menggunakan metode ad libitum sampling, scan sampling, dan focal animal sampling. Interval \Vakiu yang digunakan adalah satu meni!. M. fascicularis termasuk hewan poligarni dan tidak mempunyai musim kawin. Betina yang sedang beral.li. lebili aktif datipada biasanya, lebih sering menyerang dan juga diserang olell betina lain. Pada puncak berahinya seringkali betina dilindungi olell seekor jantan yang menyertainya. Penaikan (mOUnIing) dapat dilangsungkan dengan permohonan ataupun dengan pemmaan dan penaikan bisa terjadi secara langsung maupun tidak langsung. Ada hubungan antara penaikan dengan peringkat individu dalam kelompok. Semakin tinggi peringkat individu jantan dalam kelompok maka semakin besar pula peluang individu tersebut mendapatkan betina yang diinginkan. Betina yang mempunyai peringkat lebili linggi memperoleh kesemp.tan yang besar Imtuk mendapatkan jantan dominan. Jantan yang berbed. peringkat, masingmasing dapat memonopoli satu atau barangkali beberapa betina lvi fascicularis melakukan penaikan dengan single mount-fo-ejaculate dan multiple mount-/oejaculate. Narnunpenaikan yang sering dilakukan adalah single mount-to-ejaculate.

Judul: Perilaku seksual monyet ekor panjang (Macaca fascicularis) di Bumi Perkemahan Pramuka Cibubur, Jakarta
Abstrak: Sexual behavior is one of interaction between adult or subadult male and female that has significant role in maintaining group existency. Long-tailed macaques live in multi male multi fe~nale group, polygamous, and has no breeding season. Sosial behavior influenced by sosial hierarchy. Sexual behavior consists of mounting, intromission, thrusting, ejaculation, and dismounting. The objective of this study was to assess sexual behavior of long-tailed macaque (M. fasciszrlaris) in Bumi Perkemahan Pramuka Cihubur, Jakarta. The observation was carried out using ad libitum sampling and focal animal sampling. Daily activities were observed between 06.00 a.m. and 06.00 p.m. for 80 days (329 hour 17 minutes). Sexual activity occured in 2.33 % of total daily activity, and slowed higher frequency in the morning (06.00-10.00 a.m.) than other period of time: afternoon (10.00 a.m.-02.00 p.m.) and evening (02.00-06.00 p.m.). Sexual activity was identified has higher frequency on the ground than other places. The average duration of copulatory was 4.19 second. The high rank male did a lot of copulation, and genital inspect. Mostly, copulation occured without genital inspect. Male and female monkeys are more likely to take a rest after copulation.

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.
