Judul: Kualitas Visual dan Fungsional Turfgrass pada Beberapa Waktu Awal dan Frekuensi Aplikasi Pupuk Hayati
Abstrak: Inorganic fertilization with relatively high dosage and frequency is mostly done to maintain quality, density and uniformity of turfgrass. However this practice has caused soil and water pollution. Using biofertilizer was done to reduce the use of inorganic fertilizers. The objective of the research was to study the visual and functional quality of turfgrass on several first application times and frequencies of biofertilizer application. This research was done in Bukit Pelangi Golf Course, Cijayanti, Bogor from February 2012 until August 2012. The experiment was arranged at split plots in randomized block design with two factors, which are: first application times and frequencies of biofertilizer application, in four replications. First application times as the main plot consist of four levels, which are: 1, 2, 3, and 4 weeks before planting. Frequencies of biofertilizer application as the sub-plot consists of four levels, which are: once every 1, 2, 3, and 4 weeks. The results showed that application frequency at once a week showed the best visual and functional quality and not significantly different compared to the frequency of application at once every two weeks. First application time at three weeks before planting and the frequency of application at once every two weeks was the best treatment to enhance the visual and functional turfgrass quality, which increase shoot density, leaf width, leaf color, leaf length, biomass clipping, the percentage of couverage, root length, root biomass, increased the recovery, and decreased the diameter of stolon.

Abstrak: objective of the research was to study the effect of using biofertilizer on nutrient efficiency of turf grass. The research was conducted at the Rainbow Hills Golf Course, Cijayanti, Bogor on February to May 2012. The experiment was designed at randomized complete block design with two factors and three replications. The first factor is inorganic fertilizer with four dosages (A1:100%; A2:75%; A3:50%; and A4:0% of inorganic fertilizer recommended dosage (DA)) as main plot and the second factor is biofertilizer with four dosages (H1:100%; H2:75%; H3:50%; and H4:0% of biofertilizer recommended dosage (DH)) as sub plot. The results showed that biofertilizer aplication increased coverage area, density, crown dry weight, shoot-root ratio, clipping dry weight, nutrient efficiency (uptake and use), and reduced inorganic fertilizer

Judul: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
