Judul: Pengaruh suhu rendah terhadap perkembangan telur katak batu (Rana macrodon)
Abstrak: Katak merupakan hewan yang sering digunakan sebagai bahan percobaan dalam mempelajari perkembangan embrio, karena pembuahan sel telur pada katak terjadi secara eksternal dan tahap-tahap perkembangan berlangsung dalam waktu yang relatif singkat, sehingga memudahkan dalam pengamatan. Berhubungan dengan hal ini dilakukan peneli- tian perkembangan embrio katak pada suhu rendah dan dili- hat pengaruhnya terhadap perkembangan embrio. Katak yang digunakan adalah Rana macrodon. Telur katak yang telah dibuahi ditempatkan dalam tabung reaksi yang berisi 5 cc medium Holtfreter 10%, kemudian tabung ditempatkan dalam gelas piala yang berisi air. Telur yang disimpan berada dalam keadaan stadium zigot, blastula dan gastrula. Penyimpanan dilakukan dalam tiga jangka waktu yang berbeda untuk masing-masing stadium, yaitu 8, 16 dan 24 jam. Hasil penelitian menunjukkan bahwa suhu penyimpanan berpengaruh terhadap perkembangan telur, baik selama penyimpanan maupun pada perkembangan selanjutnya setelah dipelihara pada suhu kamar. Perkembangan telur pada suhu...

Judul: Pengaruh berbagai suhuinkubasi terhadap perkembangan telur ikan mas (Cyprinus carpio L)
Abstrak: Percobaan ini bertujuan untuk mengetahui pengaruh suhu air terhadap laju penyerapan kuning telur, laju pertumbuhan embrio sebagai peubah utama dan derajat pembuahan, derajat penetasan telur, lama inkubasi, panjang larva saat menetas, volume kuning telur dan efisiensi penyerapan kuning telur ikan mas (Cyprinus carpio L.) sebagai peubah pelengkap. Rancangan percobaan yang digunakan adalah rancangan acak kelompok. Rancangan tersebut terdiri atas 3 kelompok percobaan dan masing-masing terdiri atas 5 perlakuan suhu, yaitu 23, 25, 27, 29, dan 31°C. Dalam setiap kelompok percobaan digunakan telur yang berasal dari induk mas lokal yang berbeda-beda dengan bobot tubuh berkisar antara 3-4 kg. Teknik pemijahan menggunakan metode hipofisasi dengan dosis hipofisa dari 1 kg ikan mas donor untuk setiap 1 kg ikan mas resipien. Telur disebar di dasar bak penetasan seluas 150 cm² dengan kepadatan telur antara 150-300 butir telur/baki penetasan. Baki penetasan terbuat dari lempengan kaca yang berbentuk kotak persegi panjang berukuran 15x10 cm dan tinggi 2 cm. Pengamatan dilakukan 1 jam sekali selama 10 jam setelah fertilisasi kemudian 3 jam sekali sampai larva menetas. ...

Judul: Shopee E-commerce Customer Loyalty Model on Erigo
Abstrak: Fashion products are one of the favorite products that consumers look for when shopping online. Erigo, as a brand that sells its effects on the online marketplace Shopee has several problems, especially those related to consumer loyalty and satisfaction resulting from a shopping experience that needs to meet expectations. Based on a pre-survey conducted on 30 consumers who had purchased Erigo products, 50% of consumers were declared disloyal, 30% of consumers were stated to be dissatisfied, 47% of consumers were declared to have lost trust, and 43% of consumers were reported not to be committed to Erigo's company. This research aims to see the relationship between satisfaction, trust, and commitment to loyalty based on consumer experience Erigo. This research was conducted from March – June 2022 on respondents who bought Erigo products at the Shopee marketplace using a voluntary sampling technique. The total number of respondents in this study amounted to 347 people. The independent variable in this study is customer experience, while the dependent variable is customer satisfaction, customer trust, customer commitment, and customer loyalty. Primary research data obtained from questionnaires were processed using the SEM-PLS method in the Smart-PLS application. Based on the results of the SEM-PLS bootstrapping, several aspects of customer experience have a significant effect on customer satisfaction, including competence, helpfulness, personalization, and value for time. On the other hand, there are several aspects of the customer experience that do not have a significant effect on Erigo's customer satisfaction in the marketplace, including aspects of accessibility, customer recognition, problem-solving, and promise fulfillment. Based on the research results, several consumer experiences influence customer satisfaction, such as products that are easily accessible and purchased using payment methods that suit preferences, good Erigo product designs, detailed information on the products being sold, along with the terms and conditions of the promos they provide. Erigo also has standardization of the products they sell at Shopee. In terms of product delivery, Erigo is able to provide consumers with products according to their orders. On the other hand, there are still some unfavorable consumer experiences, such as difficulty finding product references and accessing customer service assistance. Based on the research results, customer trust and commitment statistically significantly affect customer loyalty. Meanwhile, customer satisfaction does not affect consumer loyalty. This can be influenced by several factors, for example, low consumer loyalty to e-commerce platforms, fashion products with many competing and substitute products, and the lack of emotional value a brand provides
