Judul: Peningkatan Produksi Benih Ikan Gurami (Osphronemus gouramy) menggunakan Kombinasi Hormon Oodev dan Melatonin melalui Pakan
Abstrak: Ikan gurami (Osphronemus gouramy) merupakan salah satu spesies budidaya air tawar yang memiliki permintaan tinggi. Ketersediaan benih terkendala pada produktivitas induk yang masih rendah. Hormon Oodev dan melatonin digunakan untuk mempercepat pematangan gonad dan meningkatkan produktivitas induk pada beberapa jenis ikan. Tujuan penelitian ini adalah menentukan kombinasi hormon Oodev dan melatonin yang optimal untuk memproduksi benih ikan gurami. Rancangan yang digunakan yaitu rancangan acak lengkap (RAL) dengan 3 perlakuan dan masing-masing perlakuan 3 kali ulangan. Perlakuan ke-1 diberi Oodev 0,5 mL/kg induk (kontrol), perlakuan ke-2 diberi Oodev 0,5 mL/kg induk dan melatonin 0,5 mg/kg induk (OM1) dan perlakuan ke-3 diberi Oodev 0,5 mL/kg induk dan melatonin 1 mg/kg induk (OM2). Hasil penelitian menunjukkan bahwa pemberian kombinasi Oodev 0,5 mL/kg induk dan melatonin 0,5 mg/kg induk memberikan pengaruh yang nyata terhadap nilai jumlah telur, FR dan produksi benih. Kombinasi Oodev dan melatonin dapat meningkatkan produksi benih ikan gurami sebanyak 2,1 kali. Kata kunci: ikan gurami, benih, melatonin, oodev, Giant gourami (Osphronemus gouramy) is one of the freshwater aquaculture species that has a high demand. The availability of seeds is constrained by the low productivity of the broodstock. Oodev and melatonin hormones are used to accelerate gonadal maturation and increase broodstock productivity in several types of fish. The purpose of this study was to determine the optimal combination of Oodev and Melatonin hormones to produce giant gourami seeds. The design used was completely randomized design (CRD) with 3 treatments and each treatment had 3 replications. Treatment 1 was given Oodev 0.5 mL/kg parent (control), treatment 2 was given Oodev 0.5 mL/kg parent and melatonin 0.5 mg/kg parent (OM1) and treatment 3 was given Oodev 0.5 mL/kg parent and melatonin 1 mg/kg parent (OM3). The results showed that the combination administration of 0.5 mL/kg broodstock and melatonin 0,5 mg/kg broodstock had a significant effect on the number of eggs, FR and seeds production. The combination of Oodev and melatonin can increase the production of seeds giant gourami as 2,1 times. Keywords: gourami, seeds, melatonin, oodev

Judul: The Effect of Melatonin and Oodev  through Feed to Increase Seed Production of Red Tilapia (Oreochromis sp.)
Abstrak: Kontinuitas ketersediaan benih ikan nila merah dipengaruhi oleh kemampuan reproduksi induk. Peningkatan jumlah benih ikan nila dapat dilakukan melalui rekayasa reproduksi dengan penggunaan hormon seperti Oodev dan melatonin. Tujuan penelitian ini adalah mengetahui performa produksi benih ikan nila merah dengan penambahan melatonin dan Oodev melalui pakan terhadap kualitas kematangan gonad induk dan produksi larva yang dihasilkan. Induk berukuran 100- 300 g diberi pakan yang mengandung kombinasi antara Oodev 0,5 ml/kg induk dan melatonin 0,25 mg/kg, 0,5 mg/kg, dan 0,75 mg/kg induk. Pakan diberikan secara restricted yaitu sebanyak 3% dari biomassa induk pada pagi dan sore selama 60 hari. Pemberian kombinasi Oodev 0,5 ml/kg induk dan melatonin 0,5 mg/kg induk melalui pakan merupakan dosis terbaik karena mampu meningkatkan nilai produksi sebesar 2,1 kali dari kontrol. Secara ekonomis perlakuan tersebut juga meningkatkan keuntungan sebesar 1,9 kali dari kontrol. Perlakuan penambahan melatonin tunggal terbaik yaitu pada dosis 0,75 mg/kg induk karena mampu meningkatkan produksi sebesar 1,6 dari kontrol. Pemberian kombinasi Oodev dan melatonin pada induk nila dapat meningkatkan produksi benih., The continuity of the availability of red tilapia seeds is influenced by the reproductive ability of the broodstock. Increasing the number of tilapia seeds can be done through reproductive manipulation using hormones such as Oodev and melatonin. The purpose of this study was to determine the performance of red tilapia seed production by adding melatonin and Oodev through feed for the quality of maturity of parent’s gonads and the larvae production. Tilapia measuring 100-300 g were fed a combination of Oodev 0,5 ml/kg bw and melatonin 0,25 mg/kg, 0,5 mg/kg, and 0,75 mg/kg bw. Feed is given in a restricted method, it was 3% of broodstock body weight, in the morning and evening for 60 days. The combination of Oodev 0,5 ml/kg bw and melatonin 0,5 mg/kg bw was the best dose because it was able to increase the production value 2,1 times from the control. Economically, this treatment also increases the gain 1,9 times from the control. While the best single addition of melatonin treatment is at a dose of 0,75 mg/kg bw because it can increase production 1,6 times from the control. Giving a combination of Oodev and melatonin to tilapia can increase seed production.

Abstrak: License plate is a unique code consisting of letters and numbers arrangement. Each vehicle has a license plate that serve as the identity code of the vehicle itself. Since license plates are unique, it often used for recording, such as in the parking area. The character identification characters on the license plates are made automatically using the input in the form of license plate images to facilitate the recording process. K-NN classification and feature extraction ICZ and ZCZ used in the identification of character identification. ICZ and ZCZ feature extraction obtain features by computing the character centroids and divide the image into n equal zones then computing the average distance from the character centroid to every pixel in the image. The character identification accuracy using 14 zones and ICZ are 97.00% while using ICZ+ZCZ feature extraction are 98.17%. The license plate identification accuracy using feature extraction plates ICZ+ZCZ are 72.31% for zero tolerance and 89.23% for one fault tolerance.
