<p class="IsiabstrakIndonesia"><span lang="IN">Benih merupakan salah satu aspek budidaya yang mempunyai peranan penting. Untuk mendukung pertumbuhan benih dan peningkatan produksi cengkeh, pemberian unsur hara sangat diperlukan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh frekuensi dan konsentrasi pemberian air kelapa terhadap pertumbuhan benih cengkeh. Penelitian dilakukan di Kebun Percobaan Balittro Laing Solok Sumatera Barat, sejak Maret sampai September 2014. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 12 perlakuan konsentrasi air kelapa dan frekuensi pemberian yaitu (1) tanpa air kelapa/air dan frekuensi pemberian 1 kali (0/1), (2) 0/2, (3) 0/3, (4) konsentrasi air kelapa 200 ml l<sup>-1</sup>/1, (5) 200 ml l<sup>-1</sup>/2, (6) 200 cc l<sup>-1</sup>/3, (7) 400 ml l<sup>-1</sup>/1, (8) 400 ml l<sup>-1</sup>/2, (9) 400 ml l<sup>-1</sup>/3, (10) 600 ml l<sup>-1</sup>/1, (11) 600 ml l<sup>-1</sup>/2, (12) 600 ml l<sup>-1</sup>/3; interval waktu pemberian 2 minggu, 10 tanaman per plot diulang 3 kali. Variabel yang diamati meliputi pertumbuhan tanaman (tinggi tanaman, diameter batang, jumlah daun, panjang daun, lebar daun, panjang akar, jumlah akar utama) serta biomass (bobot basah dan kering batang, daun dan akar). Hasil penelitian menunjukkan pemberian air kelapa konsentrasi 600 ml l<sup>-1</sup> dengan frekuensi pemberian satu kali, menghasilkan pengaruh terbaik terhadap pertumbuhan vegetatif benih cengkeh.</span></p>
Cinnamon is the main commodity of West Sumatra and Indonesia is the largest exporter of world markets. Cinnamon seeds are recalcitrant, so the fruit that has fallen out and is not fresh has experienced a decline in germination power. To improve the viability of cinnamon seeds, it is necessary to soak with rabbit urine. For this reason, a study was conducted to improve the quality of cinnamon seed viability through soaking in rabbit urine. This research was conducted at Balittro Laing Solok Experimental Garden from October 2017 to February 2018. The study used a completely randomized design [CRD] with 5 treatments namely rabbit urine dose: [1] without urine/water, [2] dose of 10 ml/l, [3] dose of 15 ml/l [4] dose of 20 ml/l [5] Dose of 25 ml/l, 30 seeds per box/plot and repeated 7 times. Seeds were used 7 days after harvest. Variables measured included: germination, vegetative growth of seeds [seed height, leaf number, leaf length, leaf width, stem diameter, number of roots, root length and biomass], chlorophyll analysis. The results showed that the seed germination was 60% while the vegetative growth of seed height, number of leaves, leaf length, leaf width, and stem diameter were found the best at doses 25 ml/l as well as for the variable root length, number of roots, whole wet weight, stem wet weight + leaves, root wet weight, whole dry weight, dry weight of stem + leaves, and dry weight of the root
Kacang tanah merupakan salah satu jenis kacang-kacangan yang mempunyai nilai gizi tinggi. Akan tetapi produksi kacang tanah di Indonesia masih rendah dibandingkan dengan negara lain. Untuk meningkatkan produktivitas kacang tanah perlu dilakukan penambahan nutrisi pada tanaman namun dengan mahalnya harga pupuk perlu dicari alternatif lain. Untuk itu dilakukan penelitian pemanfaatan abu limbah penyulingan serai wangi menjadi pupuk organik untuk meningkatkan produktivitas kacang tanah. Penelitian ini dilakukan di Kebun Percobaan Balittro Laing Solok sejak September sampai Desember 2017. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan yaitu pemberian abu limbah penyulingan serai wangi dengan dosis : 1) 200 g 2) 250 g 3) 300 g dan 4) 0 g pada 8 tanaman per plot diulang 6 kali. Benih kacang tanah ditanam dalam kantong berukuran 45 x 60 cm yang berisi media tanah dan pupuk kandang dengan volume 1 kg/kantong. Variabel yang diamati meliputi tinggi tanaman, jumlah cabang, jumlah polong, bobot basah, bobot kering serta bobot kering/100 biji. Pengamatan pertumbuhan dilakukan setiap dua minggu dimulai tiga minggu setelah tanam. Hasil penelitian menunjukan bahwa pertumbuhan vegetatif dan produksi tanaman kacang tanah mempunyai perbedaan yang signifikan dari setiap dosis abu limbah penyulingan yang digunakan. Dengan hasil yang terbaik pada dosis abu limbah serai wangi 300 g/kantong terlihat pada tinggi tanaman, jumlah cabang, jumlah polong, berat basah, berat kering dan berat per 100 biji berturut-turut 46,82 cm, 4,76 buah, 37,72 buah, 80,31 g, 35,40 g dan 62,36.
Cinnamomum burmanii L, a cinnamon plant developed in Indonesia, requires high-quality seeds, yet plant propagation faces challenges due to limited access to quality seeds at the appropriate time. This study aimed to determine the viability of cinnamon seeds from the level of maturity of the seeds and size. The experimental design used in this study was a randomized completed block design with a factorial pattern, with the first-factor treatment being the maturity level of the seeds, namely: 1) K1 (purple) and 2) K2 (purplish-green). The second factor was the size of the seeds, namely: 1) U1 (large size) and 2) U2 (small size) at different storage times, namely at the beginning of storage, 4,7, and 10 days after storage. The observed variables included water and carbohydrate content, germination, and seed vegetative growth (seed height, number of leaves, leaf length, leaf width, roots, and root length). The results showed that the interaction of cinnamon seeds with large size and purple maturity level had the highest viability in all storage periods. Germination reaches 70%, carbohydrate content 15.28%, and moisture content 10.51% ten days after storage.
