Celery is a commercial plant that should be cultivated. Nutrient Film Technique Hydroponic cultivation systems is one of the technologies that can be applied in a narrow area, but research of the planting medium and the concentration of nutrients in hydroponiccultivation system for celery plants are rare. This study aimed to analyze the influence interaction planting medium and nutrient concentrations on the growth and yield of celery. The design of this study used split plot design. The main plot were the concentration of nutrients (N): 1200 ppm (n1), 1300 ppm (n2), and 1400 ppm (n3). Subplot were the planting mediums (M): rockwool as control (m0), sawdust (m1), husk fuel (m2), and rice straw (m3). There were twelve combinations, with three replicates. The results showed that treatment interaction was not significant effect on growth and yield, but a single treatment of plant media rockwool and nutrient concentration of 1300 ppm able to increase the growth and yield of celery.

Daun kelor mengandung berbagai zat nutrien yang dapat melindungi spermatozoa selama kriopreservasi semen. Tujuan penelitian ini adalah untuk menguji pengaruh ekstrak daun kelor di dalam pengencer tris kuning telur terhadap kualitas semen beku kambing peranakan Boer. Semen segar dibagi ke dalam empat buah tabung reaksi dengan volume yang sama, kemudian disentrifugasi dengan kecepatan 3.000 RPM selama 20 menit. Plasma semen dibuang, dan sedimen (spermatozoa) diencerkan dengan empat pengencer berbeda sebagai perlakuan. Penelitian menggunakan rancangan acak lengkap dengan empat perlakuan, yakni: 73% pengencer dasar tris + 20% kuning telur + 7% gliserol tanpa ekstrak daun kelor (kontrol), 71% pengencer dasar tris + 20% kuning telur + 7% gliserol + 2% ekstrak daun kelor (EDK-2), 69% pengencer dasar tris + 20% kuning telur + 7% gliserol + 4% ekstrak daun kelor (EDK-4), dan 67%pengencer dasar tris + 20% kuning telur + 7% gliserol + 6% ekstrak daun kelor (EDK-6). Semen dikemas di dalam straw mini, diekuilibrasi di dalam lemari es pada suhu 5oC selama empat jam dan dibekukan dengan cara meletakkan straw 10 cm di atas permukaan nitrogen cair selama 15 menit. Peubah yang diamati adalah persentase motilitas, persentase hidup, dan persentase membran plasma utuh (MPU) spermatozoa dievaluasi setelah pengenceran dan thawing. Hasil penelitian menunjukkan bahwa penambahan ekstrak daun kelor ke dalam pengencer tris kuning telur dapat mempertahankan kualitas spermatozoa semen beku kambing peranakan boer. Penambahan sebanyak 4% ekstrak daun kelor merupakan konsentrasi terbaik dalam menghasilkan semen beku kambing peranakan boer. Persentase motilitas spermatozoa setelah thawing pada perlakuan kontrol, EDK-2, EDK-4, dan EDK-6 masing-masing adalah 41,25%, 45%, 50%, dan 47,5%. Dapat disimpulkan bahwa penambahan 4% ekstrak daun kelor ke dalam pengencer tris kuning telur merupakan konsentrasi terbaik dalam menghasilkan semen beku kambing peranakan boer.

This research was conducted in August - November 2019 in Tungkaran Village (Maju Bersama Farmer Group) Martapura Kab. Banjar, South Kalimantan Province and Laboratory of Agroecotechnology Production, Faculty of Agriculture, ULM Banjarbaru. This experiment used a completely randomized design (CRD) 2 factors which included 5 doses of N fertilizer (first factor) and 4 doses of bokashi fertilizer (second factor) with 2 replications. The results of this research stated that the most significant impact on the interaction of N and bokashi fertilizers were plant height (28 dast and 35 dst), plant wet weight, plant dry weight, number of seeds / rows, many cob weighted and many ears without weight. sweet corn plants, namely the N fertilizer at a dose of 90 kg N/ha to 180 kg N/ha as well as the bokashi fertilizer at a rate of 15 tons/ha.
