Judul: Penentuan Luas Optimal Hutan Kota Berdasarkan Rosot Gas Karbondioksida (CO2) di Kota Medan Provinsi Sumatera Utara.
Abstrak: Medan is one of the metropolitan city in Indonesia, which continues to grow as a center of activity of the economy, industry, trade and services. This prompted an increase in energy consumption and discharge residual energy such as gas carbon dioxide (CO2) into the atmosphere. Increasing carbon dioxide has led earth's global temperature increase. One alternative solution to reduce CO2 emissions in the atmosphere is the development of the urban forest. This study aims to determine the optimal area of urban forest by sinks of CO2 gas produced by human use of fossil fuels, livestock and rice cultivation. The study was conducted by literature study, observation, and interpretation and analysis of Landsat image. Carbon dioxide emissions in Medan in 2013 was 2 901.69 Gg so the urban forest area required was 49 807.94 ha. It was predicted that CO2 emissions in 2030 will reach to 1 375 762.80 Gg and therefore the required optimal urban forest area was 23 615 164.42 ha. Today, the urban forest area that available in Medan is only 43.32 ha, so the addition of the urban forest area is still needed.

Judul: Penentuan Luasan Optimal Hutan Kota Berdasarkan Emisi Karbondioksida (CO2) di Kota Cilegon Provinsi Banten
Abstrak: Cilegon is one of the industrial cities that experience development are rapidly. Density of population activities such as transportation and industrial activity led to an increase in water and air pollution and temperature. This research was intented to know the optimal area of urban forest based on carbon dioxide emissions in the air that are generated by fuel oil, Liquid Petroleum Gas, coal, humans, cattle, and rice fields and also know the location of potentially managed as urban forest. methods of research conducted is the literature studies, interviews, preparation work, direct observation and ground check. Cilegon has eight locations of urban forest with a total area 26.11 ha. Carbon dioxide emissions are produced in Cilegon city amounted to 13240029 tons/year, necessitating the addition of city forest 227243.89 ha. The value of Carbon dioxide emissions in 2030 is 3924365870 ton, so land required is 67362298 ha. The potential for urban city is residential area, public cemetery, the beach, empty land industry with long term development plan, and road network.

Judul: Trichuriasis pada anjing
Abstrak: Tulisan ini bertujuan menguraikan trichuriasis pada anjing meliputi etiologi, epizootiologi, daur hidup, pato- genesa, gejala klinis, diagnosa, diagnosa banding, progno- sa, dan pengobatan berdasarkan berbagai acuan kepustakaan. Pada tulisan ini lebih ditekankan mengenai segi klinisnya terutama tentang diagnosa, pencegahan, dan pengobatannya. Trichuriasis pada anjing adalah infeksi/radang akut cecum dan colon yang disebabkan oleh parasit cacing Tri- churis vulpis Froelich, 1789. Terdapat di mana-mana di seluruh dunia dan menyerang hampir semua jenis ternak se- perti anjing dan rubah, kucing, rodentia, babi, ruminantia primata, dan manusia. T. vulpis bersifat zoonosis, penu- laran terjadi melalui makanan dan minuman yang terkontami- nasi telur infektif. Daur hidupnya bersifat langsung dan sederhana. Telur yang dikeluarkan cacing betina di luar tubuh induk semang tidak menetas, tetapi mengalami perkembangan larva di da- lam telur. Bila telur infektif termakan, maka di dalam tubuh induk semang akan menetas dan selanjutnya berkembang menjadi cacing dewasa yang hidup di cecum dan colon an- jing. Masa prepaten T. vulpis sangat beragam berkisar an- tara 28-35 hari (Jubb dan Kennedy, 1970) sampai 70-197 ha- ri (Kirk dan Bistner, 1985), dengan rata-rata 10 minggu...dst
