ANALISA PENGARUH MEDIA ONLINE DAN HARGA TERHADAP KEPUTUSAN PEMBELIAN PADA BISNIS CIKAKE

Perkembangan zaman membuat semakin canggihnya teknologi yang ada, tidak terkecuali perkembangan media daring. Perkembangan tersebut semakin banyak berkembang dari waktu ke waktu terutama di Indonesia yang membuat setiap pelaku usaha memanfaatkan peluang yang ada. Harga merupakan elemen penting dari suatu bisnis jika ingin menjual produknya. Perbedaan harga dari tiap pelaku usaha dapat  membuat calon konsumen akan berpikir 2 kali sebelum membeli produk tersebut. Keputusan pembelian merupakan suatu pengambilan keputusan oleh konsumen mengenai produk apa yang akan dibeli. Penelitian ini bertujuan untuk menguji pengaruh media daring dan Harga terhadap Keputusan Pembelian pada bisnis Cikake. Populasi dari penelitian tidak diketahui karena merupakan konsumen Cikake dari tahun 2018 hingga 2020 yang tidak memiliki data yang pasti dan berlokasi di Pandaan. Metode pengambilan sampel dengan menyebarkan kuesioner daring menggunakan barcode yang ditaruh pada stand Cikake di Foodland Pandaan. Penelitian ini menggunakan model analisis regresi linier berganda. Hasil penelitian didapatkan bahwa nilai signifikansi baik variabel media daring dan harga adalah 0.000 yang berarti variabel tersebut berpengaruh signifikan terhadap variabel Keputusan Pembelian. Kata Kunci: media daring, harga, keputusan pembelian &nbsp

ADDITIONAL DESCRIPTIVE DATA FOR THE NEW COELACANTH, Latimeria menadoensis Pouyaud et al. FROM SULAWESI, INDONESIA

Morphometries and meristies data of Latimeria menadoensis, a new species of Coelacanth from Sulawesi, Indonesia (Pouyaud et al. 1999) are reported. Comparison with data of L. chalumnae as reported by McAllister and Smith (1978) and Forey (1998) are presented. Among the 22 descriptive characters only 41% are different. Some more specimens of L. menadoensis are still needed for more detail study of its morphological differences with L. chalumnae.Keywords: L. menadoensis, description, L. chalumnae, morphometries andmeristies comparison

Ekologi Makan Ikan Glyptothorax Major (Blgr) (Bagaridae, Siluriformes) Di Sungai Alas, Aceh Tenggara

Berita Biologi. 3(8): 396 399.A study on the feeding ecology of Glyptothorax major (Blgr) was conducted in the Alas River South East Aceh, Sumatra during early dry season, January 1983.Index of Preponderance analysis showed that this species is a benthic-insect feeder It was found that the food habit of immature and mature fish is slightly different.The mature fish\u27s food habit is more varied than the immature\u27s. Based on the concept of the "availability factor"of prey species,a tendency was also found that the mature fish is a more opportunistic of using food resources than the immature\u27s.The supposed mechanisme of this difference and its relation with condition factor values is discussed

NOTES ON FOOD, GROWTH AND REPRODUCTION OF HOMALOPTERA AMPHISQUAMA TA (WEBER and DE BEAUFORT), (BALlTORIDAE) FROM ALAS RIVER, ACEH, SUMATRA ISLAND

Approximately 253 specimens of freshwater fish Homalopteraamphisguamata (Weber and de Beaufort) were collected during dry and rainy seasons from the upper reached of Alas river, Sumatra island in 1981-1983. Their food, growth and reproduction were studied. Phytoplanktonic algae, especially Bacillariophyceae and small aquatic insects are their food preference. The growth pattern was different between sex, that is allometric for the male and isometric for the female.Relatively, there is no difference of condition factor between sex (0.850 for the male and 0.848 for the female). However, tne'vaiues were different between seasons. The mixed value in average was around 0.934 in rainy season and around 0.775 in dry season. Total fecundity highly varied from 63 up to 470 or 93 in average. The bigger size of the fish tended to show higher fecundity value. The percentage number of matured gonads during the rainy season was 8.89-22.55 % and in dry season was 8.21-18.33%. The diameter of matured eggs was around 2.01 mm in average

Insect community of stream ecosystem of Ketambe forest, Gunung Leuser National Park, Aceh, Berita Biologi 3.(3) : 111 -115.Non-strictly seasonal study on the insect community of stream ecosystem at Ketambe forest, Gunung Leuser National Park,Aceh was undertaken from September 1980 to February 1983,with the aim of providing base line data of the local stream ecosystem. Thirty two species of benthic insects were recorded from the depth between 5--30 cm.They belong to the orders of Diptera, Odonata, Kphemeroptera, Coleoptera, Plecoptera, Hemiptera, Megaloptera and Trichoptera. The number of species found was higher during the beginning of the dry than that of the rainy season (96,9% vs 59,4% of the total). Diptera and Odonata showed the highest number of species (8) among the orders, whereas Trichoptera was the lowest (one species). However, in term of frequency of occurence and abundance, the Trichoptera species, Hydropsyche sp,, was the highest, followed by Neoperla sp. (Flecoptera). There was a tendency of seasonal fluctuation in species number and life cycle in several species. Bottom structures containing pebbles, boulders of various sizes and leaf litter for shelter and feeding site, appeared to be the best habitat. Species composition or number varied with stations. However, diversity indexes among stations were more or less similar, and all of them were low
