PERTUMBUHAN STEK KOPI ROBUSTA (Coffea canephora) DENGAN PEMBERIAN EKSTRAK BAWANG MERAH

Indonesia is one of the largest coffee producing and exporting countries in the world. Most of the production is robusta variety. Coffee is the fourth largest foreign exchange earner for Indonesia after palm oil, rubber and cocoa and is a source of income for the community. Coffee can be developed in a generative (seed) and vegetative way, including using cuttings. Efforts to accelerate the formation of roots in cuttings can be done by using natural growth regulators, one of which is shallots which contain auxins. The purpose of this study was to examine the effect of shallot extract on the growth of robusta coffee cuttings (Coffea canephora). This research was conducted from December 2019 to February 2020 at Campus II, Batanghari University (Pijoan). The design used in this study was a completely randomized design (CRD) with one treatment factor, namely shallot extract including; .k0 (without giving onion extract), k1 (250 g of shallots in 1 liter of distilled water), k2 (500 g of shallots in 1 liter of distilled water), k3 (750 g of shallots in 1 liter of distilled water), and k4 (1000 g of shallots in 1 liter of distilled water). Each stage of the experiment was repeated 3 times, so that there were 15 experimental plots, for each experiment there were 10 cuttings with a total of 150 cuttings. The observed data were analyzed using analysis of variance followed by the DNMRT test at α 5%. From the immersion treatment in 750 g of shallot extract in 1 liter of distilled water (k3), there was an increase in the percentage of live cuttings 47.37%, the percentage of shoots and roots growth of 83.51%, 106.06% of shoot length, and 98.03% of roots. , and the root dry weight of 225.27% compared without giving onion extract (k0).

Grafting bibit kopi memiliki tujuan menghasilkan tanaman dengan karakteristik terbaik dari dua varietas kopi yang disambungkan. Kopi robusta digunakan sebagai batang bawah, karena lebih tahan terhadap kondisi yang tidak menguntungkan di lahan gambut. Upaya peningkatan ketahanan batang bawah dapat memanfaatkan mikoriza dan disambungkan dengan kopi liberika sebagai batang atas. Penelitian ini bertujuan untuk mendapatkan bibit kopi Liberika unggul hasil grafting dengan kopi Robusta bermikoriza serta mendapatkan panjang entres kopi Liberika yang mampu meningkatkan pertumbuhan bibit kopi Liberika hasil sambung pucuk. Percobaan ini menggunakan Rancangan Acak Lengkap faktorial dengan dua faktor dan empat ulangan. Faktor pertama adalah inokulasi mikoriza (tanpa aplikasi mikoriza dan aplikasi mikoriza gabungan Glomus sp-1a dan Glomus sp-3c) dan faktor kedua berupa panjang entres (10, 15, 20 dan 25 cm). Parameter yang diamati adalah persentase keberhasilan sambungan, waktu pecah tunas, pertambahan tinggi bibit, pertambahan jumlah daun, jumlah tunas, bobot kering tunas, dan infeksi mikoriza. Hasil penelitian menunjukkan respons bibit kopi Liberika hasil grafting dengan bibit kopi Robusta bermikoriza terbaik diperoleh pada panjang entres 15 cm, sedangkan yang disambungkan dengan Robusta tidak bermikoriza diperoleh pada panjang entres 25 cm. Pertumbuhan bibit kopi Liberika hasil grafting dengan bibit kopi Robusta terbaik pada berbagai panjang entres diperoleh pada kopi Robusta bermikoriza.” The main goal of coffee grafting is to create a crop with the best characteristic of two coffee varieties in one plant. Robusta coffee is used as the rootstock, which is more resistant to constraints and unfavorable conditions in the peatland. The effort to increase rootstock resistance is inoculated by mycorrhizae and grafted with Liberica coffee as the scion. This study aimed to obtain the best scion length in order to increase the growth of Liberica coffee with Robusta coffee as the inoculated rootstock. The experiment used factorial completely randomized design with the first factor was mycorrhizae inoculation (without inoculation and inoculation of Glomus sp-1a and Glomus sp-3c combination) and the second factor was the length of scion (10, 15, 20 and 25 cm). The variables observed were the percentage of success grafted plants, shoot break time, growth (plant height, number of leave, number of shoots, and shoot dry weight) and mycorrhizae infection. The results showed that the plant inoculated by mycorrhizae and scion lenght of 15 cm gave the best percentage of the success graft, shoot break time, and growth of scion. While, the root stock without inoculation showed the best result with the scion length 25 cm. The best growth of grafted plant was obtained in all scion length with mycorrhizae inoculation.

The objective of this study was to determine if shading and DCPTA application interactively influence seedling emergence and shoot growth of Hypoestes phyllostachya Bak. seedlings. Hypoestes `Carmine Red' seeds were soaked for 6 h in distilled water, and then soaked 6 h in solutions containing' 10 mg DCPTA/liter (30 mM) and 0.1% Tween-80, 0.1% Tween-80, or distilled water. Date of seedling emergence was recorded after sowing (0.5 cm) in 9-cm (460 ml) pots filled with 440 ml of a 5 pine bark: 4 Florida sedge peat: 1 sand medium. Forty pots from each of the three seed-soak treatments were grown under 30%, 63%, or 84% shading, provided by saran-type shadecloth, using natural photoperiods (completely randomized design). Shoot heights and dry weights were recorded 75 days after sowing. Neither shading nor DCPTA influenced total seedling emergence or seedling emergence rate (time to 50% emergence). Under 30% shading, seedlings from DCPTA-treated seeds were taller and had more shoot dry weight than seedlings from surfactant- or water-treated-seeds; however, DCPTA did not influence seedling height or shoot weight under 63% or 84% shading.

Coastal Land

Hibiscus tiliaceus L. is a seaside plant that has several benefits, one of which is as a producer of paper fiber. H. tiliaceus need a better nutrient to grow on coastal land that is still constrained by the high level of salinity. By this, a special treatment is needed to support its growth. One of them is the application of mycorrhizal inoculants. Mycorrhizae is known as one of the fungi that can help plants tolerate salinity. The aims of the research were to determine the effect of AMF inoculants and determine the best doses of AMF to the seedling growth. The research used completely randomized design with 5 treatments and 5 replications. The treatments were (A) without AMF (control), (B) inoculation AMF 10 g/plant, (C) inoculation AMF 15 g/plant, (D) inoculation AMF 20 g/plant and (E) inoculation AMF 25 g/plant. The result showed that AMF can infect the roots of hibiscus seedlings with an infection degree of 18-34%. However, it has not been able to have a significant effect on shoot length, number of leaves, dry weight of root, and dry weight of shoot.

High methane oxidation activity of local isolated methanotrophic bacteria have a potent as methane gases reducing agent while combined with nitrogen fixing bacteria as paddy biofertilizer. The aim of the research was to evaluate the effectiveness of the bacteria as methane gases reducing agent and biofertilizer in paddy plantation. The research was arranged in a completely randomized design consisted of fertilizer types and watering system treatments with four replicates. The research showed that paddy shoot length was not affected by the treatment. On the other hand, both plant freshand dry weight, as well as the number of productive tiller were affected by interaction of fertilizer types and watering system. Fertilizer types affected grain per panicle and methane flux after fertilization. In the end of paddy vegetative stage, bacterial fertilizers were capable to reduce methane emission in different rate. The different result in methane flux was likely due to the interaction between soil local microorganisms and soil chemical component.
