Judul: Prestasi akademik siswa-siswa SMA jurusan IPA dan hasil ujian masuk proyek perintis tiga di Universitas Sam Ratulangi Manado
Abstrak: Suatu hambatan bagi perguruan tinggi untuk menerapkan sistem penerimaan mahasiswa baru tanpa melalui ujian masuk di Sulawesi Utara adalah kurang atau tidak adanya informasi tentang keadaan mutu pendidikan dari SMA-SMA yang ada di daerah tersebut. Penelitian ini menccba memberikan gambaran tentang mutu pendidikan SMA-SMA di daerah Sulawesi Utara dengan menggunakan data nilai rapor siswa selama di SMA (18 peubah) dan nilai ujian masuk Proyek Perintis Tiga di Universitas Sam Ratulangi Manado, tahun 1982. Analisis statistika yang digunakan dalam penelitian ini adalah analisis faktor. Dua buah faktor yang digunakan dalam analisis faktor untuk mereduksi ke-18 peubah nilai rapor, ternyata mampu menjelaskan kembali total keragaman data ke-18 peubah yang diteliti sebesar 55 persen. Faktor pertama dapat diidentifikasi sebagai faktor matematika dan IPA, serta faktor kedua sebagai faktor bahasa. Penggolongan SMA atas dasar nilai skor faktor menurut faktor matematika dan IPA serta nilai ujian masuk, menunjukkan bahwa SMA yang berlokasi di luar Manado cenderung memberikan nilai rapor tinggi kepada siswanya, tetapi prestasi siswanya di ujian masuk rendah jika dibandingkan dengan SMA yang berlokasi di Manado. Sedang­ kan menurut faktor bahasa dan nilai ujian masuk, SMA yang berlokasi di Manado cenderung memberikan nilai rapor tinggi kepada siswanya, tetapi prestasi siswanya di ujian masuk rendah jika dibandingkan dengan SMA yang berlokasi di luar Manado.

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
