Judul: Pengaruh Gonadotropin Releasing Hormone (GnRH) Terhadap Produktivitas, Siklus Bertelur Dan Biometri Organ Reproduksi Serta Hubungannya Dengan Konsentrasi Progesteron Serum Ayam Lokal (Gallus domesticus)
Abstrak: This experiment was conducted to study the effect of Gonadotropin Releasing Hormone (GnRH) on productivity, egg laying cycle of the domestic fowl (Gallus domesticus) and its effect on serom Progesterone concentration, number of growing follicles and weight of the ovary, oviduct and biometry of the reproductve organs. Ten rna/lire female hens were used in this research. These hens were devided randomly into the GuRH and control group consisting of five hens each. The GnRH group was injected intramuscular into the pectoral muscle with 1 mL of 50pg/mI. GnRH, while the control group was injected with 1 mL of 0,9% saline for seven conseccutive days. The results showed significant (P<0,05) elevated producth;ty in the laying period (12 months) of the GnRB group from 50,601:0,75 eggs to 67,71:1:0,15 eggs as compared to that of the control group from 64,92x1,00 eggs to 40,521:0,30 eggs. GnRH injection, improved the egg laying cycle patterns as compared to the normal egg laying cycle by decreasing the lag time in a laying period (12 months) from 98,33:1:0,39 days to 68,00:0,81 days significantly (P<0,05) while the control group from 84,40:0,33 days to 71,33:0,78 days. Serom Progesterone concentration of the GnRH group (7,63; 1,93; 3,57; 2,92 ng/mL) increased and reached its peak significantly as compared to the control group (0,15; 0,01; 0,74; 0,98 ng/mL) on day 1, 2, 5 and 7 of treatment. The number of growing follicles (the number of F4, F5 follicles; F1, F2, F3 follicles weight) also increased significantly (P<0,05) in the GnRH group as compared to the control group, concomitant with the increasing ovarian and oviduct weight (p<0,05) in the GnRH group (37, 65:1, l6; 50,43:,58 g) aS compared to the control group (28,50:1,00; 31,15:1,65 g). GnRH also increased significanly (P< 0,05) the biometry of the reproductive organs. From this research it could be concluded that responsiveness of GnRH injection could increased Progesterone concentrations, resulting ill the number of follicular growth F4, F5 and ultimately Fl, F2, F3 increased egg production and repaired egg laying cycle. GnRH also increased weight of the ovaries, oviduct alld hiomelfy of the reproductive organs.

Judul: Peranan hormon dan induksi ovulasi pada unggas
Abstrak: Hormon ovarium yang berperan dalam pengaturan sekresi gonadotropin dan siklus ovulasi adalah hormon Progesteron dan Estrogen. Kedua hormon itu secara menyolok meningkat dalam plasma darah menjelang ovulasi, kemudian turun ke keadaan normal pada saat ovulasi, kecuali estrogen yang masih tampak tinggi beberapa jam setelah ovulasi. Progesteron yang meninggi sebelum ovulasi tersebut merangsang hipotalamus yang selanjutnya mempengaruhi hipofisa untuk menghasilkan hormon-hormon gonadotropin yang penting dalam pembentukan telur dan ovulasi. Jadi dalam hal ini progesteron memberikan effek positif feedback terhadap pelepasan hormon gonadotropin. Estrogen juga dihasilkan di ovarium, dan konsentrasi- nya meningkat menjelang ovulasi sampai beberapa jam setelah ovulasi. Estrogen bersama progesteron mempunyai effek positif feedback terhadap pelepasan hormon gonadotropin men- jelang ovulasi, tetapi jika hanya estrogen effek positif feedback tidak terjadi. ...

Judul: Analysis of Value Creation for Seva.id Based on Brand Consideration Metrics
Abstrak: Kondisi pasar yang potensial dan tren membuat Seva.id hadir sebagai platform otomotif digital terintegrasi yang melayani jual beli mobil baru dan bekas milik ASTRA. Namun demikian, kehadiran Seva.id belum memberikan dampak positif bagi ASTRA, kondisi penjualan mobil dari ASTRA sendiri pada Juli 2019 cenderung menurun 19,1% dibandingakan periode tahun lalu. Pencapaian Seva.id terhadap jumlah pengunjung tahun 2019 juga menurun 39,25% dari tahun sebelumnya. Seva.id sering melakukan promo flash sale, namun capaiannya hanya 10% untuk target register. Penelitian ini bertujuan untuk mengidentifikasi masalah dalam value creation Seva.id dengan pemetaan Value Proposition Canvas (VPC) 0, merumuskan matriks Brand Consideration Seva.id, merumuskan Kerangka Kerja Empat Langkah dan memformulasikan value proposition Seva.id yang sesuai dengan preferensi konsumen. Dari VPC 0 didapatkan Seva.id sebagai platform all in one untuk purchase managing mobil baru atau bekas dengan fitur lengkap. Kemudian, nilai tersebut dikaji dengan perspektif konsumen sehingga menghasilkan elemen-elemen matriks Brand Consideration yang terbagi menjadi 2 jenis yaitu 7 elemen fungsional, diantaranya informs, quality, variety, makes money, reduce effort, reduce cost, dan organized. Sedangkan, 2 elemen emosional, diantaranya reduce anxiety dan provide access. Kerangka Kerja Empat Langkah memetakan 15 nilai yang ditingkatkan dan delapan nilai baru potensial untuk Seva.id. Nilai tersebut diformulasikan dalam dalam VPC 1.0., Potential market conditions and trends make Seva.id present as an integrated digital automotive platform that serves the buying and selling of new and used cars owned by ASTRA. However, the presence of Seva.id has not had a positive impact on ASTRA, the condition of car sales from ASTRA itself in July 2019 tended to decrease by 19.1% compared to last year's period. Seva.id's achievement of the number of visitors in 2019 also decreased by 39.25% from the previous year. Seva.id often does flash sale promos, but only 10% of the achievement is for the target register. This study aims to identify problems in Seva.id value creation by mapping Value Proposition Canvas (VPC) 0, formulating the Seva.id Brand Consideration matrix, formulating a Four-Step Framework and formulating a Seva.id value proposition that suits consumer preferences. From VPC 0, Seva.id is found as an all in one platform for purchasing managing new or used cars with full features. Then, the value is examined with a consumer perspective to produce Brand Consideration matrix elements which are divided into 2 types, namely 7 functional elements, including information, quality, variety, making money, reduce effort, reduce cost, and organized. Meanwhile, 2 emotional elements, including reduce anxiety and provide access. The Four-Step Framework maps 15 improved values and eight potential new values for Seva.id. This value is formulated in VPC 1.0.
