The Effect of Green Tonic Fertilizer and Pearl NPK Fertilizer on the Growth of Forestero Cocoa Plant Seeds (Theobroma cacao L) The aim of this study was to determine the effect of Green Tonic, NPK Mutiara and the extraction of Green Tonic and NPK Mutiara on cocoa seedling growth. This research was carried out at Gunung Panjang Samarinda Seberang East Borneo. with a time of ± 3 months, starting from April to July 2016. The design of the study used factorial randomized block design (RCBD) 4 x 4 with a number of replications 3 times, with factorial analysis. The treatment consists of 2 factors. The first factor is the administration of POC Green Tonic consisting of 4 levels, namely: p0: Without treatment, p1: 2 ml / 1 Liter of Green Tonic Concentration, p2: 3 ml / 1 Liter of Water Tonic Concentration, p3: 4 ml Green Tonic Concentration / 1 Liter of Water, The second factor was the administration of NPK Mutiara consisting of 4 levels, namely: v0: Without treatment, v1: Giving NPK Mutiara Fertilizer 50 grams / polybag, v2: Giving NPK Mutiara Fertilizer 100 grams / polybag, v3: Giving NPK Fertilizer Pearl 150 grams / polybag. From the analysis of variance showed that the effect of giving green tonic liquid organic fertilizer (P) was the best on the parameters of stem diameter of 30 DAP and 60 DAP of cocoa plants achieved by the treatment of p3 (4 ml / 1 Liter of Water Green Tonic Concentration), NPK Mutiara fertilizer (V) the best in the parameters of plant height 30 DAP, 60 DAP and 90 DAP, stem diameter 30 DAP and 90 DAP, number of leaf 60 DAP, leaf area 30 DAP cocoa plants achieved by v3 (Giving NPK Pearl Fertilizer 150 gram / polybag) while for stem diameter 60 DAP, number of leaves 30 DAP achieved by v1 (Giving NPK Mutiara Fertilizer 50 g / polybag), for the number of leaves 90 DAP, the area of Leaves 60 DAP and 90 DAP achieved by v2 (Giving NPK Pearl Fertilizer 100 g / polybag), The best interaction of POC green tonic and NPK pearl (PV) fertilizer on stem diameter parameters 30 DAP and 60 DAP, number of leaves of 90 DAP, leaf area of 60 DAP and 90 DAP was achieved by p3v2 (4 ml / 1 Liter Water + Green Tonic Concentration Pearl NPK fertilizer 100 grams / polybag. The difference for 30 HST leaf area is achieved by p1v3 (2 Ton / 1 Liter Water + Green Tonic Concentration + 150 gram Pearl NPK Fertilizer / polybag).

Borneo Prima tangerine (Citrus reticulata cv Borneo Prima) is an indigenous plant from Tanjung Labu Village, Rantau Pulung District, East Kutai District, East Kalimantan Province. In the cultivation of these plants, there are pathogens that can cause a decrease in crop yields. This study aims to identify the diversity of rhizosphere microbial populations in Borneo Prima tangerine plants. The study was conducted at the Laboratory of Plant Pests and Diseases of the Faculty of Agriculture, Mulawarman University Samarinda in February-April 2018. This study was descriptive, using a survey method. The study consisted of two stages, namely (1) soil sampling on Borneo Prima tangerine citrus land in Makroman Village, Kutai Kartanegara Regency, East Kalimantan (2) isolation, characterization, identification, gram test, in the Laboratory of Pests and Plant Diseases. The data obtained were analyzed using quantitative descriptive analysis. The results of the study of the isolation of rhizosphere microbes in Borneo Prima tangerine citrus plants obtained 1 family of bacteria namely Azotobacteraceae and 4 fungal genera including Aspergilus, Mucor, Penicillium and Trichoderma. Microbes that belong to the group that benefit the soil ecosystem are Azotobacteraceae because they play a role in fixing (fixation) N2 or as biofertilizers. While the genus Mucor and Penicillium act as decomposers and Trichoderma acts as a controller of pathogens or biological agents and biological pesticides (biopestiside).

The study in Dusun Desa Sumber Jaya Manunggal Jaya Rt. 09 District of Tenggarong Seberang Regency. this study used a draft split plot with factorial 3 x 4 consisting of three replications. the first factor is Superfarm Rhizobium which comprise three levels: ie s0 (without treatment), s1 (2 g / plant), s2 (4 g / plant). The second factor is the dose of N fertilizer consists of four levels ie N0 (without fertilizer) n1 (2.5G / plant) n2 (5g / plant) and n3 (7,5g / plant) . the results showed that treatment of Rhizobium Superfarm Award (S) had no significant effect on all parameters. While the provision of fertilizer N (N) significantly affected plant height parameter parameter 2, 4 and 6 weeks after planting. and at a dose of 7.5 g significantly the parameters of crop seed weight, seed weight per plot, the production results (Ton ha-1). The highest production was achieved by treatment s0n3 483.33 g / plot, equivalent to 2.69 Toh ha-1.

Onions Tiwai is one plant in Borneo forest used by people as a traditional medicine. One of the efforts to support increased production of onions tiwai is through the cultivation of technology media including by the use of appropriate planting and the provision of the Micro Organisms Local (MOL). The aim of research to know the influence of MOL conch mas on growth and yield of onion tiwai and to determine the best planting medium for the growth and production of onions tiwai. The study was conducted over four months starting from nursery seedlings until harvest. This study uses a randomized block design (RBD) with a 4 x 4 factorial experiment consisting of three replications. The first factor is the Growing Media which comprises four levels: ie m0 (Control), m1 (Topsoil and sand), m2 (Topsoil and Rice Husk) and m3 (Topsoil, Rice Husk and Sand). The second factor is the concentration of microorganisms Local (MOL) snails consists of four levels ie p0 (control) p1 (100 ml / liter water) p2 (200ml / liter of water) and p3 (300 ml / liter). The results showed that treatment of the planting medium (M) significantly affected the parameters of the number of leaf age 60 DAP and is not significantly affected, plant height, number of tillers, the number of bulbs, tubers and the weight of the growing media pH. While the provision of MOL Keong Mas (P) had no significant effect on all parameters. There is no interaction between the treatment plant and the provision of various media MOL Keong Mas on all parameters observed.

The study was conducted to determine the effect of bran composition and baglog size on the production of white oyster mushrooms (Pleurotus ostreatus). The study was arranged in a Randomized Block Design (RBD) consisting of 2 factors with 5 replications. The first factor is the composition of bran consisting of four levels, namely: 10%, 15%, 20% and 25%. The second factor is the size of baglog which consists of 4 levels, namely: 17 cm, 18 cm, 19 cm and 20 cm. The results showed that the composition of bran had a very significant effect on the age of the first harvest, average mushroom weight, average fresh weight per baglog and biological efficiency ratio. Baglog size has a significant effect on the age of the first harvest, average mushroom weight, average fresh weight per baglog and biological efficiency ratio. The best effect on the production of oyster mushrooms is produced by the composition of bran 20% (d3) and baglog size of 19 cm (b3). The interaction of bran composition and baglog size significantly affected the age of the first harvest and had a very significant effect on the average weight of mushrooms, but did not significantly affect the fresh weight of mushrooms per baglog and the ratio of biological efficiency. The best interaction with the production of white oyster mushrooms is a combination of 20% bran composition and 19 cm baglog size.
