Judul: Kajian Hubungan Arsitektur Pohon dan Kehadiran Burung di Kampus IPB Dramaga Bogor
Abstrak: Trees play a major role for creating the landscape characteristic and also functions as a habitat for many birds. Trees has characteristic created by canopy and branches shape that differ each other. The research goals were to analyze the tree diversity based on its architecture, bird species richness, trees usage level by birds, and the influence given by tree architecture to bird presence. This research was conducted by divide IPB Dramaga campus into observation plots by size 300m x 300m. Then each plot was observed the trees physic include its canopy, branches, leaf size, flower and fruit existance and birds presence on the selected trees. In this research gained 99 sample trees that divided into 24 observation plots with 27 species of birds on the sample trees. From the result of analysis seen that parameter of the trees that influence bird presence are branches shape and flower existance, with model Y = 0,566 + 2,777 X1 + 2,543 X2. From the reference and research result we knew that bird most prefered tree with vertical branch and have flower on it. From this research result also recommended some tree species that can attract more birds.

Judul: Pemanfaatan Habitat oleh Burung pada Habitat Situ di Kampus IPB Darmaga dan Sekitarnya
Abstrak: Kawasan hijau kampus IPB Darmaga memiliki potensi keanekaragaman hayati yang tinggi. Penelitian di Situ di Kampus IPB Darmaga dan sekitarnya menunjukkan situ merupakan habitat penting bagi burung. Dampak perubahan bentang alami karena pembangunan di daerah urban seperti di Kota Bogor dapat mengancam keberadaan situ sebagai habitat alami burung. Oleh karena itu, penelitian ini penting dilakukan untuk mengetahui pemanfaatan habitat situ dan sekitarnya oleh kelompok burung. Penelitian ini dilakukan pada April-Mei 2018 di empat situ yaitu Situ LSI, Situ Gede, Situ Burung, dan Situ Panjang. Metode yang digunakan yaitu metode titik hitung (IPA) dan observasi. Hasil penelitian menunjukan, terdapat 38 jenis burung dari 21 famili dari semua lokasi penelitian. Nilai keanekaragaman tertinggi berada di Situ LSI (H’= 2,300), sedangkan nilai keanekaragaman terendah di Situ Burung (H’= 1,853). Berdasarkan habitat utama yang digunakan, kelompok burung yang dominan adalah burung terestrial. Keanekaragaman burung di habitat situ dapat dipengaruhi oleh perbedaan tutupan vegetasi di sekitarnya. Oleh karena itu, untuk mempertahankan keanekaragaman burung yang tinggi penanaman vegetasi di sekitar situ menjadi penting.

Judul: Demulsification process with salt, acid, surfactant and commercial demulsifier to accelerate emulsion wastewater treatment
Abstrak: One solution to overcome the problems of wastewater emulsion is demulsification process. The basic principle of this process is the separation of water and oil contained in emulsion wastewater using demulsifier, a chemical that serves as an emulsion breaker. This study aims to compare and find the best demulsification process and quickly using various types of demulsifier in the emulsion Oil in Water (O/W). From the results of initial tests on samples of emulsion wastewater used oil and used cooking oil known salt as the best demulsifier in separating oil and emulsions in the 5th minute because it showed significantly different results (α = 0.05). Also, it has neutral pH, the smallest turbidity, as well as color and water quality of the samples tested to be more clear with a little foam. The best salt for emulsion wastewater used oil is NaCl, whereas for emulsion wastewater used cooking oil is CaCl2. Testing continued in order to obtain the best concentration (0,02 M; 0,03 M; 0,05 M) of both types of salt is related to its ability to demulsification process. The test results of the election of the best concentration of demulsifier selected shows that all concentrations gave similar results in separating oil and emulsions in the 5th minute of emulsion wastewater used oil and cooking oil. However, the results of other tests (pH, turbidity, and salinity) showed 0,02 M NaCl concentration gave the best results for used oil. Its pH values 6, the smallest turbidity and salinity 81,5 FTU and 1700 ppm. The emulsion wastewater used cooking oil also showed that the 0,02 M CaCl2 concentration gave the best result. Its pH value 5 with the smallest turbidity and salinity 78 FTU and 2800 ppm.
