Judul: Pengaruh Pengungkapan Sustainability Report terhadap Kinerja Pasar pada Perusahaan dalam Kelompok Indeks SRI-KEHATI
Abstrak: Banyak perusahaan belum menerbitkan sustainability report. Jika dilihat kinerja pasar pada Indeks SRI-KEHATI yang anggotanya merupakan perusahaan yang menerbitkan Sustainability Report kinerja pasarnya cenderung naik dibandingkan dengan kinerja pasar Indeks LQ45 yang tidak semua anggotanya menerbitkan sustainability report. Tujuan penelitian untuk menganalisis kinerja fundamental perusahaan kelompok Indeks SRI-KEHATI yang berkinerja tidak lebih baik daripada perusahaan kelompok Indeks LQ45, dan menganalisis pengaruh pengungkapan kinerja ekonomi, kinerja sosial, kinerja lingkungan, dan kinerja fundamental terhadap kinerja pasar pada kelompok Indeks SRI-KEHATI dan kelompok Indeks LQ45. Teknik pengambilan sampel dengan purposive sampling menghasilkan Sampel sebanyak 48 perusahaan. Metode dalam penelitian ini menggunakan analisis regresi linier berganda. Berdasarkan hasil penelitian variabel independen yang berpengaruh signifikan adalah Hutang jangka panjang (DER), Aktivitas dari perputaran total aset (TATO), Pengungkapan kinerja lingkungan, (EnDI) berpengaruh positif signifikan terhadap perubahan kinerja pasar perusahaan yang ditunjukkan oleh PBV. Sedangkan pengungkapan kinerja sosial memiliki pengaruh yang negatif dan signifikan terhadap variabel dependennya.

Judul: Analisis Pengaruh Kapitalisasi Pasar, Likuiditas dan Profitabilitas Terhadap Return Saham Pada Indeks LQ45
Abstrak: Pada tahun 2018 rata-rata harga saham pada perusahaan indeks LQ45 mengalami penurunan yang disebabkan oleh faktor fundamental dan non-fundamental yang berimbas pada kinerja keuangan perusahaan. Tujuan dari penelitian ini adalah menganalisis pengaruh kapitalisasi pasar, likuiditas dan profitabilitas terhadap return saham pada indeks LQ45. Metode analisis data yang digunakan adalah regresi linier berganda. Sumber dan jenis data yang digunakan adalah data sekunder dengan jenis data kuantitatif. Hasil penelitian secara parsial menunjukkan bahwa kapitalisasi pasar berpengaruh positif terhadap return saham perusahaan pada indeks LQ45. Sedangkan current ratio, return on equity, dan earning per share tidak berpengaruh terhadap return saham perusahaan pada indeks LQ45. Hasil penelitian secara simultan menunjukkan bahwa variabel kapitalisasi pasar, current ratio, return on equity, dan earning per share berpengaruh sebesar 8.4% terhadap return saham perusahaan pada indeks LQ45.

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
