Judul: Keberhasilan Pengajaran Matematika dan Faktor-Faktor yang Mempengaruhi pada SMA Jurusan IPA di Sulawesi Selatan
Abstrak: Tujuan penelitian ini adalah ingin melihat tingkat keberhasilan pengajaran matematika dan faktor-faktor yang mempengaruhi pada SMA jurusan IPA di Sulawesi Selatan,berdasarkan kurikulum SMA tahun 1975. Data dan informasi diperoleh dari hasil wawancara, kuesioner, uji coba dan nilai semester akhir dalam bidang studi matematika. Uji coba dilaksanakan pada lima SMA (Tiga SMA Negeri dan dua SMA Swasta)dalam Kotamadya Ujung Pandang, sebagai SMA contoh. Dari tiap SMA contoh dipilih 20 orang siswa untuk mengikuti uji coba dan mengisi kuesioner. semua siswa dipilih dari kelas III jurusan IPA. Dalam uji coba itu digunakan soal dari BP3K, yang dianggap mempunyai keterandalan dan kesahihan yang tinggi.

Judul: Keberhasilan pengajaran matematika dan faktor-faktor yang mempengaruhi pada SMA jurusan IPA di Sulawesi Selatan
Abstrak: Tujuan penelitian ini ialah ingin melihat tingkat keberhasilan pengajaran matematika dan faktor-faktor yang mempengaruhi pada SMA jurusan. IPA di Sulawesi Selatan, berdasarkan kurikulum SMA tahun 1975. Data dan informasi diperoleh dari hasil wawancara, kuesioner, uji coba dan nilai semester akhir dalam bidang studi matematika. Uji coba dilaksanakan pada lima SMA (Tiga SMA Negeri dan dua SMA Swasta) dalam Kotamadya Ujung Pandang dan enam SMA (Empat SMA Negeri dan dua SMA Swaeta) luar Kotamadya Ujung Pandang, sebagai SMA contoh. Dari tiap SMA contoh dipilih 20 orang siswa untuk mengikiuti uji coba dan mengisi kuesioner; semua siswa dipilih dari kelas III jurusan IPA. Dalam uji coba itu digunakan soal dari BP3K, yang dianggap mempunyai keterandalan dan kesahihan yang tinggi. Dari hasil wawancara dan kuesioner diketahui bahwa pada tahun ajaran 1982/1983 terdapat 49 SMA Negeri dan 135 SMA Swasta yang tersebar dalam 23 daerah Kabupaten/Kotamadya di Sulawesi Selatan. Masih diperlukan tambahan sebanyak 43 gedung dengan 257 ruang kelas untuk dapat menampung lulusan SMP yang akan melanjutkan pelajaran ke SMA. Guru matematika yang dibutuhkan sebanyak 164 orang, yang ada 75 orang,

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
