Pengaruh Efek Sisaan Eco Enzyme dan Pupuk Kandang Ayam terhadap Pertumbuhan dan Produksi Selada

A study consisted of two growing seasons of lettuce was held to observe the residual effect of eco enzyme and chicken manure on the growth and yield of lettuce on the second growing season.  The research was held in Medan and was done using factorial randomized block design, with two treatments and three replications.  The first factor was the concentration of eco enzyme, with three levels of 0, 1 and 2 ml/L.  The second one was the dose of chicken manure, with three levels of 0, 15 and 30 tons/hectare.  The application of the eco enzyme and chicken manure was done only on the first growing season. The parameters were: number of leaves, root volume, fresh weight and the total yield of lettuce. The result showed that there was a residual effect of eco enzyme and chicken manure application on the growth and production of lettuce.  The concentration of eco enzyme had a very significant effect on the number of leaves at 14 DAP, but there was no significant effect on other parameters. The relationship between eco enzyme concentration and the number of leaves at 14 DAP was linear.  The dose of chicken manure had a very significant effect on all variables at each time of observation. The relationship between the dose of chicken manure and the number of leaves at 14, 21 and 35 DAP, the fresh and total yield was also linear. The relationship between the dose of chicken manure and the number of leaves at 28 DAP and the root volume was quadratic, with the optimum doses of chicken manure were: 27.05 and 22.5 tons/ha, respectively.  No interaction was observed between the concentration of eco enzyme and the dose of chicken manure on all variables at each time of observation

Masalah Kebijakan Sertifikasi Benih Dan Bibit Tanaman Hutan Di Jawa Barat (Penerapan Pendekatan Advocacy Coalition Framework)

The purpose of this study is to obtain policy direction recommendations for seed source, seed and seedling certification in West Java using ACF (Advocacy Coalition Framework) approach and multiple linear regression. A key alignment of the two goals for the government is compliance with statutory or government-sponsored regulations, with the result that the stability of seed production is disrupted by suppliers. Analysis using the ACF framework has produced policy guidelines for mandatory certification of seed quality related to seed source, seed quality, and compliance with regulations issued by central governments. The objectives of the activity to certify seed sources, seed quality and seed quality in accordance with the P.3 policy were not optimally achieved. This is reflected in the prominence of those who are less active in certifying the forest products they produce.Merchant certification activity has a significant value of 0.023. Vendor certification activities are reduced due to the P.3 policy requiring local governments to have their own forest plant nurseries. Procurement and distribution agencies generally produce on a large scale when they receiv

Respon Pertumbuhan Protocorm Like Bodies (PLB) Anggrek Tebu (Grammatophyllum scriptum Blume) terhadap Modifikasi Media Murashige and Skoog (MS) secara In Vitro

Anggrek Tebu (Grammatophyllum scriptum) propagation can be improved optimally by adding plant growth regulators such as BAP and NAA through in vitro technique. Murashige and Skoog (MS) medium is an essential medium for plant tissue growth that needs another complex mineral and vitamin to develop the protocorm-like bodies (PBL) of Anggrek Tebu. Hence, this study aimed to gain the appropriate composition of modified MS by adding BAP and various coconut water concentrations and to evaluate their effect on PBL of Anggrek Tebu growth (budding time, number of buds, and leaves). The research was conducted using a completely randomized design with two factorials such as modified MS medium (MS (M1), ½ MS (M2), and ¼ MS (M3))and coconut water concentration (0 ml/L (C0), 100 ml/L (C1), 200 ml /L (C2), and 300 ml/L (C3)) with triplication. The result showed that the fastest budding time was remarkable growth from M2C1 offered the bud at three weeks after planting (WAP). In the number of budding, M3C2 showed excellent results and significantly increased the budding growth at 8.33 ± 0.88  in 10 WAP. Meanwhile, the highest leave number was M2C1 at 23.00 ± 3.60, followed by M2C2 and M3C2, respectively, at 20.67 ± 1.45 and 20.67 ± 1.33. This result indicated that modifying MS medium composition by adding the coconut water could assist the PBL of Anggrek Tebu growth in a specific concentration.
