Judul: Suatu Penilaian NMR Kumulatif terhadap NMR TPB sebagai Gold Standard (Studi Kasus Mahasiswa IPB  Angkatan 30 - Angkatan 33)
Abstrak: Tingkat kesesuaian (degree of agreement) diantara suatu metode pengukuran dengan metode gold standard sering diamati dalam berbagai bidang ilmu. Penduga Laurent, penduga gabungan (blended estimator) dan batas kesesuaian 95% ( 95% limit of agreement ) dapat digunakan sebagai kriteria untuk mengkuantifikasi tingkat kesesuaian diantara metode-metode pengukuran.

Judul: Hubungan antara gaya menulis mahasiswa Institut Pertanian Bogor dengan nilai mutu rataan kumulatifnya
Abstrak: Keragaman merupakan masalah dasar dalam ilmu statiti- ka. Keragaman yang dapat diamati pada mahasiswa IPB, dua di antaranya ialah keragaman dalam tingkat kelancaran belajar dan keragaman dalam gaya menulisnya. Dengan ber- titik tolak dari kedua hal tersebut di atas, maka dilakukan penelitian untuk mengetahui hubungan antara ga- ya menulis mahasiswa dengan tingkat kelancaran belajarnya yang dicerminkan oleh NMR kumulatifnya. Penelitian ini dilakukan di Institut Pertanian Bogor mulai dari bulan Pebruari 1988 sampai bulan Juni 1988. Objek yang ditelaah ialah karya tulis mahasiswa IPB ang- katan 18 dan 19, yaitu mereka yang menjadi mahasiswa pada tahun ajaran 1981-1985 dan 1982-1986. Karya tulisnya di- kelompokkan berdasarkan NMR kumulatifnya, yaitu kelompok I (2.00-2.25), kelompok II (2.26-2.75), kelompok III (2.76- 3.00) dan kelompok IV (3.01-4.00). Bagian yang ditelaah dari karya tulis tersebut ialah bagian pendahuluan, hasil dan pembahasan serta kesimpulan dan saran. Hal ini dimaksudkan agar jurusan/fakultas tidak berpengaruh terhadap peubah yang ditelaah (dan, pada, yang, dengan koma dan jumlah kata per kalimat). ...

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
