Judul: Pendugaan Parameter Demografi Monyet Ekor Panjang (Macaca fascicularis Raffles 1821) di Situ Sangiang Taman Nasional Gunung Ciremai.
Abstrak: Long-tailed macaque (Macaca fascicularis Raffles 1821) have wide use in biomedical research hence being exported to many countries, such as China and U.S.A. Indonesia is one of many countries that export long-tailed macaque. Even so, they often have conflict with humans. Situ Sangiang which is located at Sangiang Resort in Taman Nasional Gunung Ciremai (Mt. Ciremai National Park) is one of many habitats of long-tailed macaque. This research aims to discover demographical parameters of long-tailed macaque at Situ Sangiang, which are population size, birth rate, mortality rate, sex ratio, and age structure. This research was held at 3-12 March 2015 using concentration count method towards three groups of long-tailed macaque. The data collected from the site indicated that population of long-tailed macaque at Situ Sangiang is 76 individuals with an average size of 25.33 ± 8,40 individuals per group. Sex ratio in the groups are 1:1.4 for makam group, 1:1.5 for cideres group, and 1:1.2 for ranca group with progressive population structure that will ensure the prosperity of long tailedmacaque population.

Judul: Studi Populasi dan Habitat Monyet Ekor Panjang (Macaca fascicularis) di Cagar Alam Pananjung Pangandaran Jawa Barat
Abstrak: Pananjung Pangandaran Nature Reserve is one of natural habitat for long-tailed macaque (Macaca fascicularis). This wildlife was listed as Least Concern status in IUCN (2013) and Appendix II in CITES. The result of the research, which was done in three observation tracks, showed a different density of long-tailed macaque. The greatest population density was found as Karang Pandan (22 ind/ha), while at second track (Tadah Angin) were 4 individuals/ha, and at the third track (Cikamal) there were 19 individuals/ha. The range of population at the first track as many as 22 ± 9 individuals, at the second track as many as 4 ± 2 individuals, and third track as many as 7 ± 4 individuals. The adult long-tailed macaque was found at most in this research. Sex ratio of long-tailed macaque at the first and third track was 1:4, and at the second track was 1:3. There were 48 plant species that were found in the area where the long-tailed macaque carried out their activity, and 22 of the species had potential for long-tailed macaque feed.

Judul: Epoksida Minyak Jarak Pagar Sebagai Pemlastis Film Polivinil Klorida
Abstrak: Komponen penyusun plastik terdiri atas dua jenis, yaitu komponen utama berupa polimer (resin) yang merupakan komponen terbesar dari bahan plastik dan aditif. Aditif adalah komponen yang sangat penting pada plastik, walaupun hanya dalam jumlah sedikit tidak lebih dari 5%. Aditif digunakan pada plastik untuk meningkatkan sifat fungsionalnya seperti ketahanan terhadap api, kekuatan, dan fleksibilitas. Salah satu zat aditif paling penting adalah pemlastis (plasticizer). Pemlastis menguasai 65% dari 7.5 juta ton pasar zat aditif di dunia yang setara dengan US$7,6 miliar. Kegunaan utama, yaitu sekitar 90%, digunakan untuk polivinil klorida (PVC). Bahan pemlastis ditambahkan pada PVC agar tidak bersifat kaku dan rapuh dan pemlastis terbesar yang digunakan sekarang ini diambil dari kelompok senyawa ftalat (ester turunan dari asam ftalat). Pemlastis jenis ftalat seperti dietilheksil adipat (DEHA), dietilheksil ftalat (DEHP), dan dioktil ftalat (DOP) merupakan pemlastis berbahan dasar minyak bumi (petrokimia) yang dikategorikan berbahaya dan toksik.
