Judul: Keberadaan Burung Kowak Malam Kelabu (Nycticorax nycticorax Linnaeus, 1758) di Kampus IPB Darmaga.
Abstrak: IPB Darmaga, exactly around the LSI lake is one place of black-crowned night-heron. The bird is nocturnal and rest during the day. The purpose of this study was to determine the presence of black-crowned night-heron (Nycticorax nycticorax Linn.) at LSI which includes the population, behavior and habitat use, and disturbance these birds in IPB Darmaga. The method used is concentration count for the population in morning and evening, population structure, behavior or activity of using habitat, and disturbance for black-crowned night-heron. The average number of birds population that coming (in the morning) is 185 individuals and going (in the evening) is 209 individuals. The value of the t test for morning and evening observations is showed significantly different. Population structure of black-crowned night-heronis consisting 116 individuals of adult and 80 individuals of juvenile. The bird behavior that most often done is silence or resting on the rubber trees (Hevea brasiliensis) and pinetrees (Pinus merkusii). Habitat of black-crowned night-heronwas disturbed by human activity, but birds can adapt to many activities in the vicinity.

Judul: Pelestarian burung kepodang (Oriolus chinensis maculatus di Kampus IPB Darmaga
Abstrak: Tujuan penelitian adalah untuk mempelajari usaha peles- tarian burung Kepodang kuduk hitam (Oriolus chinensis) di kampus IPB Darmaga dengan mengamati habitat, populasi, pe- rilaku dan persepsi masyarakat. Pengamatan terhadap burung Kepodang kuduk hitam dilakukan pada kondisi terkurung dan kondisi bebas. 11 IT Populasi dihitung dengan cara consentration count yaitu penghitungan setiap burung Kepodang kuduk hitam yang terdapat di dalam plot pengamatan. Habitat diamati dengan melakukan analisa vegetasi dan persepsi masyarakat diamati dengan melakukan wawancara. Dan populasi burung Kepodang kuduk hitan. di desa Babakan Darmaga adalah 74 ekor dengan kepadatan populasi 0,22 ekor per hektar. Lokasi yang diamati adalah Arboretum Fakultas Kehuta- nan, kebun karet dan tanaman pekarangan di sekitar kompleks perumahan dosen (RW V). Arboretum Fakultas Kehutanan luas- nya 0,36 hektar, terdapat 41 jenis pohon dengan 29 jenis tanaman bawah. Jenis pohon yang paling dominan adalah Jeunjing (Albizia falcataria) dan kayu afrika (Maesopsis e-menii), sedangkan tanaman bawah didominasi oleh Otthocla nodosa. Kebunkaret didominasi oleh pohon karel (loven brani- liensis) jenis pohon lain adalah beringin (Ficus benjamina), Jeunjing (Albizia falcataria) dan kelapa sawit (Eluesis gu- naensis). Tanaman bawah ada 46 jenis dan yang paling domi- nan adalah Ottochloa nodosa. Pada plot pengamatan ditemukan kolam dan aliran sungai kecil. Di pekarangan perumahan dosen terdapat 15 jenis pohon dengan kerapatan 149 pohon per hektar. Jenis yang paling dominan adalah rambutan (Nephelium lapaceum) dan cengkeh (Eugenia aromatica). Pepohonan yang dimanfaatkan burung Ke- podang kuduk hitam sebagai relung berperilaku adalah Jeunjing (Albizia falcataria), beringin (Ficus benjamina), puspa (Schima noronhae), laban (Vitex pubescens), rambutan (Nephelium lapaceum), durian (Durio zibethinus), alpukat (Persea americana), karet (Hevea brasiliensis) dan muncang (Gmelina arborea). Dengan demikian jenis-jenis pohor ter- sebut disarankan sebagai tanaman pengganti pohon karet yang telah dan akan dikonversi di kampus IPB Darmaga. Ferilaku burung Kepodang kuduk hiter (Oriolus chinensis) adalah perilaku makan, minum perjalanan, berkicau, mandi, berjemur, istirahat, meregang tubuh, menggoreskan parruh,..dst

Judul: Pengaruh Lama Reaksi dan Laju Alir SO3 pada Produksi Surfaktan Methyl Ester Sulfonate Acid (Mesa) dari Metil Ester Jarak Pagar (Jatropha curcas L)
Abstrak: Surfactant is an active agent which could reduce surface tension. Surfactant could be found in cleaning agent, emulsifier, and homogenizer. Applications of surfactant are in detergent industry, food and beverage industry, and oil industry. According to its hydrophilic complex we could divide surfactant into four groups which is anionic surfactant, cationic surfactant, amphoteric surfactant, and non-ionic surfactant. Anionic surfactant is the most needed surfactant in the world Methyl ester sulfonates Acid (MESA) are one of the anionic surfactant which is renewable. One of the prospective feedstock of MESA is jatropha curcas. The dominant fatty acid of jatropha curcas oil is C16 unti 18. This fatty acid will have good detergency if it converted to surfactant. Jatropha curcas also doesn’t compete with food as a industry feedstock. Sulfonation method to produce MESA are falling film method with Single Tube Falling Film Reactor (STFR) 5 liter scale. The feedstock are jatropha curcas oil which is converted to methyl ester trough esterification process and continued with trans-esterification process (es-trans). The reactant which is used is sulfur trioxide (SO3). This reactant is chosen because it more reactive and produce less sludge than H2SO4 or Na2SO3 reactant. This research scope is only cover MESA production. MESA is an intermediate product for MES which is not purified yet. The goal of this research is to know the effect of reaction time and reactant flow rate to physic-chemical characteristic of MESA. The levels of reaction time are 30, 45, 60, 75, and 90 minutes. The SO3 reactant flow rate levels are 2,2, 2,8 dan 3,0 kg/hour. Analyses of MESA cover interfacial tension, surface tension reduction, iodine value, active matter content, acid value, and pH. . The range of interfacial tension of MESA are 1,1-4,43 dyne/cm. The
