The purpose of this study was to determine the population of mealybugs before and after application of the fungus Beauveria bassiana, to determine the mortality of mealybugs after application of the fungus Beauveria bassiana, and to determine the appropriate dose of the fungus Beauveria bassiana to control mealybugs. This research was conducted from early April to July 2021 and took place in the community garden in Teluk Kedondong Village, RT 22, Sempaja Utara Village, North Samarinda District. The study used purposive sampling method with 4 doses of Beauveria bassiana repeated 5 times (B0 = Control), (B1 = 5 g/ Liter of water), (B2 = 10 g/ Liter of water), (B3 = 15 g/ Liter of water). ). Based on the results of the study, the identification of the attack rate of mealybugs (Pseudococcus citri) on cocoa (Theobroma cacao L.) and efforts to suppress its attack with the fungus Beauveria bassiana, it can be concluded that: After application of the fungus Beauveria bassiana the population of mealybugs showed a decrease. The mortality of mealybugs after application of the fungus Beauveria bassiana was 100%. The best and most effective dose in suppressing the attack of mealybugs is 5 g/liter of water. To suppress the attack of mealybugs, it is recommended to use a dose of 5 g/liter of water by spraying it on the fruit and then wrapping it in plastic so that the fungus can be more effective.

Low soil fertility rates and not yet intensive crop cultivation have an impact on the declining trend on tomato production in the eastern multiplication. Low productivity of tomatoes due to low quality of seedlings and pest and disease attacks. Efforts to increase tomato production have been carried out, among others, by improving cultivation techniques, namely by improving the physical properties of the soil by adding organic materials and adding nutrients using inorganic fertilizers. The design of this study is; Complete randomized design with factorial analysis 2 x 4 and repetition as much as 3 times. In the first factor, the media mixture consists of 2 levels, namely T0 = Soil, T1 = Mixture of soil, manure, and chaff (2:1:1). The second factor is the combination of fertilizer K and P consists of 4 stages, namely: P0 = without fertilizer, P1 = 5gram KCL and 15grams SP-36, P2 = 10 grams KCL and 15 grams SP-36; P3 = 15 grams KCL and 15 grams SP-36. The number of polybags in the study is 24 with a per polybag size of 30 x 40 cm. The results showed the addition of manure and chaff gave clear results to the growth and production of tomatoes. The application of KCl and SP-36 fertilizers affect the high growth of plants but does not affect the production of tomato plants. Recommendations for the use of organic materials and KCL fertilizers, SP-36 is applied separately

As well as the growing influence of media mixing different grain size of the seed to growth frangipani Japan (Adenium crimsonstar). This study aims to determine the effect of mixing different media as well as the planting of seed size on seed growth frangipani Japan (Adenium crimsonstar). The study was conducted in April through July 2010, in the district of Ulu Loa Janan, Kutai regency. This study uses a completely randomized design (CRD) with 4 x 3 factorial analysis consisted of four replications. The first factor is the growing media 4 levels: m0: sand medium (control), m1: sand + fine brick (3: 1), m2: sand, ground roasted (3: 1), m3: finely + sand + bricks ground fuel (2 : 1: 1). The second factor is the size of the seed 3 levels: b1: weight 0,02gram / 0.9 to 1.0 cm long seed / seed, b2: 0,01gram / 0.5-0.7 cm long beans / seeds, b3: weight of 0,008 gram / seed length from 0.3 to 0.4 cm / seed. The results showed that treatment Growing Media significant effect on all parameters of the study. Treatment m2 (sand + soil fuel) showed the highest plant height is 5.44 cm, while the treatments m1 (fine brick sand +) showed the smallest plant height is 3.07 cm, the results showed that the different treatment of seed size did not significantly affect all parameter studies. Media interaction and different planting seed size showed no significant difference in all parameters of the study.

The Effect of Empty Bunch of Palm and Chalk of Dolomit Giving as Mixture of Plant Media to Growth of Palm Seedling (Elaeis quenensis Jacq) in Main Nursery. Target of research to know the effect of empty bunch of palm and chalk of dolomit giving as mixture of plant media to growth of palm seedling ( elaeis quenensis jacq ) in main nursery. The research was conducted on three months, since March until May 2010 in Palm plantation PT. Rea Kaltim Plantations, Perdana Village, Kembang Janggut District, Kutai Kertanegara Regent. The research was arranged in factorial completely randomized design (Factorial CRD) with factorial experimental design 3 x 3, and 3 replications. The first factor was the empty bunch of palm (T), that consisted 3 levels, they were: (t0) = without the empty bunch of palm/polybag, (t1) = 2kg of the empty bunch of palm/polybag, (t2) = 4kg of the empty bunch of palm/polybag and the second factor was the chalk of dolomit (K), that consisted 3 levels, they were: (k0) = without the chalk of dolomit /polybag, (k1) = 0,2kg of the chalk of dolomit /polybag, (k2) = 0,4kg of the chalk of dolomit /polybag. The result showed that the best result reached by 2kg of the empty bunch of palm/polybag as mixture of plant media to growth of palm seedling ( Elaeis quenensis Jacq ) in main nursery. The chalk of dolomit gave different result, treatment was not significantly influence because not be assisted with activator to quicken the empty bunch of palm dekomposition so that its result can be exploited for the growth of palm seedling. Each factor that was the empty bunch of palm and was the chalk of dolomit given separate factor to growth of palm seedling in main nursery.

This research was conducted at the Experimental Garden of Widya Gama Mahakam University Samarinda, Faculty of Agriculture, Jalan KH. Wahid Hasyim. The study was conducted in January - April 2020. This study used a factorial randomized block design (RBD) with 2 treatment factors and 3 replications. The first factor was the application of banana stem compost with various concentrations of EM4 consisting of 4 levels, namely P0 = banana stem compost without EM4, P1 = banana stem compost with EM4 concentration of 50 ml L-1 water, P2 = banana stem compost with EM4 concentration of 75 ml. L-1 water, P3 = banana stem compost with a concentration of EM4 100 ml L-1 water and the second factor is the dose of urea fertilizer which consists of 4 levels, namely, D0 = control, D1 = 1 g urea / polybag, D2 = 2 g urea / polybag, D3 = 3 g urea / polybag. The results of the research giving banana stem compost with variations in the concentration of EM4 and the dose of urea fertilizer and the interaction of the two treatments had a very significant effect on plant height at the age of 20, 40, 60 and 80 DAS, with the best treatment P3 = 28.67 cm, D3 = 28, 21 cm and P3D3 = 32.33 cm, then had a very significant effect on the number of shoots at the age of 60 and 80 DAS with the best treatment P3 = 6.67 fruit, D3 = 6.17 fruit and P3D3 = 8.33 fruit, and very influential significant on the number of leaves at the age of 40, 60 and 80 DAS with the best treatment P3 = 8.58 strands, D3 = 8.83 strands and P3D2 = 10.67 strands.
