Judul: Keanekaragaman Jenis Felidae Menggunakan Camera Trap di Resort Pemerihan-Way Haru, Taman Nasional Bukit Barisan Selatan.
Abstrak: Taman Nasional Bukit Barisan Selatan bekerjasama dengan beberapa organisasi non pemerintah yang bergerak di bidang pelestarian hidupan liar, salah satunya dengan Wildlife Conservation Society Indonesia Program (WCS-IP). Salah satu kegiatan rutin yang dilakukan setiap tahunnya adalah survei mamalia vertebrata terestrial seperti jenis Felidae menggunakan camera trap yang berlokasi di Resort Pemerihan-Way Haru. Tujuan penelitian ini adalah untuk mengidentifikasi karakteristik habitat, menganalisis keanekaragaman jenis, mengidentifikasi penyebaran, menganalisis tumpang tindih wilayah jelajah serta pola aktivitas dari jenis Felidae di Resort Pemerihan-Way Haru, Taman Nasional Bukit Barisan Selatan, Lampung. Teknik pengambilan data melalui analisis vegetasi dan tangkap-tangkap kembali. Indeks nilai penting mendominansi pada tingkat tumbuhan bawah adalah Etlingera sp. (INP = 11.23), tingkat semai dan pancang adalah Mallotus miquelianus (INP = 15.03) dan (INP = 17.51), tingkat tiang Dillenia excelsa (INP = 37.53) dan tingkat pohon Dracontomelon dao (INP = 14.89). Jenis satwa Felidae yang berhasil terekam melalui camera trap sebanyak dua jenis yakni kucing batu (Pardofelis marmorata) (RAI = 0.14; n = 2) dan kucing hutan (Prionailurus bengalensis) (RAI = 0.14; n = 2). Pola aktivitas dan tumpang tindih tidak dapat disimpulkan.

Judul: Kelimpahan Jenis Mamalia Menggunakan Kamera Jebakan di Resort Gunung Botol Taman Nasional Gunung Halimun Salak
Abstrak: Gunung Halimun Salak National Park has many ecosystem types. The national park has many rare and protected species especially mammals. The objective of this study was to identify and quantify the abundance of mammals in the national park. The abundance of mammals was calculated using camera trap of Busnell type. To support the data, direct observation, setting of live trap, mist net, identification of foot print and analysis of vegetation were also conducted. The result showed that the highest abundance of mammals was deer (Muntiacus munjak) of 31.25% with an encounter rate of 34.37 photo/100 day, while the lowest was malaysian wood rat (Rattus tiomanicus), treeshrew (Tupaia javanica), plantain squirrel (Callosciurus notatus), malay badger (Mydaus javanensis), leopard cat (Prionailurus bengalensis), and banded linsang (Prionodon linsang) of 3.12%. By using direct observation, live trap and foot print it was showed that there were another 11 species mammals of 6 families. A total of 23 mammals species of 12 families recorded during this study in the national park.

Judul: Model Input-output dalam Masalah Network Flow
Abstrak: Production process is a process, which is done by industry, to transform input into output. According to the type of output and its activity, industry can be classified into various sectors, which are connected to each other. Therefore, a model to analyze the connection among sections is needed. The model is known as input-output model (IO model). IO model presents an IO table, which shows informations about the transaction between goods and services in each economic sector. Furthermore, the IO model also shows that the amount of all input is the same as the amount of all output. In this paper, the transaction of each economic sector in IO table is analyzed using network flow theory. The formulated network flow problem implies that each sector represents partly as a producer and also as a consumer. This paper also solves a minimum cost circulation problem.
