Abstract

Farmers generally plant pepper on ultisol soil. Ultisol soil is classified as acid mineral soil which has a wide distribution, but has the potential to develop agricultural land including pepper plantations. The tendency of land used for agricultural activities shows a decrease in soil fertility, indicated by the occurrence of erosion, imbalance of nutrients present in the soil and stronger soil dependence on fertilizer, as well as lower crop production. The research aims to find out the characteristics of pepper land, productivity, potential land for the development of pepper plants in Muara Badak District. This research was carried out using survey methods with stages including; overlaying land maps, interviews, secondary data inventory, in the form of data on the number of farmers, land area, production and cultivation techniques, and analysis of soil samples in the laboratory. The results showed that the population / ha of pepper plants was different for each farmer, where the spacing was 110 x 110 cm, 120 x 120 cm, 130 x 130 cm and 140 x 140 cm with a population between 1300 - 4500 staples / ha. Farmers generally use lodrin organic fertilizer, but are not carried out intensively, and the land management system does not pay attention to the aspect of soil conservation, farmers' land has been cultivated for generations without using terraces and soil cover. The tendency of nutrient loss on the land is quite high because the land is located on a hill and is quite steep at 16-40% slope. Pepper productivity in the study area is quite high, with an average of 1,437 kg / ha. The highest productivity in Salo Palai village reached 1970 kg / ha, while the lowest in Batu Batu village was 830 kg / ha. The results of soil analysis in the two study locations that the content of the element N was classified as medium, the total K was classified as high to very high. pH and CEC are low, this can affect nutrient absorption, so that lime is needed and the addition of organic matter if fertilization is carried out.

Abstract

Rutai banana plants are local plants from Kutai Kartanegara Regency. But the existence of this plant has begun to be rare in the farmer's garden. Rutai bananas are small and are very popular for many people because of their distinctive aroma and sweet taste with high vitamin content. The small fruit shape is very suitable to be an appetizer at restaurants or food stalls. The Kutai Kartanegara District Government has made Rutai banana as an obligatory appetizer in Kutai Kartanegara. From the results of research on rutai banana fertilization on farmers' land shows very high productivity so it is necessary to do research to determine the growth of rutai banana planted intercropping with food crops. This is because the rutai banana plant uses a spacing of 3 mx 3 m, so that between banana plants there is still room that can be used for cultivation of food crops. This study aims to examine the effectiveness of NPK Phonska fertilization and the type of intercropping in rutai banana cultivation. This study used a Randomized Block Design (RBD) consisting of 4 treatments with 5 replications. Intercropping treatment consists of 4 levels, namely: s0 = without intercropping, without fertilization, s1 = without intercropping and NPK Phonska fertilizer 0.5 kg / tree, s2 = intercropping of chili and Phonska NPK 0.5 kg / tree , s3 = intercropping of corn plants and 0.5 kg / tree Phonska NPK fertilizer. Data obtained from observations were analyzed by variance and further testing with BNT at the level of 5%. Research activities include (1) land preparation (2) planting rutai banana seeds and ginger seedlings (3) Phonska NPK fertilizer treatment (4) Bioculture fertilizer treatment (5) POC Nasa fertilizer treatment (6) maintenance (7) data collection. The results showed that NPK Phonska fertilization was 0.5 kg / tree and intercropping with corn plants showed the best growth of rutai banana.

Abstract

Planting with a lane system in palm sugar and cacao plants is a technique of plantation cultivation that aims at soil conservation and microenvironment. Plant cultivation in the field needs to get a supply of fertilizer to increase crop productivity. This study aims to determine the effect of giving SP-36 and KCl fertilizer to the best growth of sugar palm and cacao plants in the planting of path systems. The research was conducted on land in Badak Mekar Village, Muara Badak District, Kutai Kartanegara Regency, East Kalimantan. The research method used a Randomized Block Design (RBD) and repeated 4 times. Factorial experiments consisted of 2 factors, as the first factor was SP-36 fertilizer (p) consisting of 3 levels: p0 = 0 kg plant-1 (control); p1 = 0.25 kg of plant-1; p2 = 0.5 kg of plant-1. The second factor was KCl (k) fertilizer consisting of 3 levels: k0 = 0 kg plant-1 (control); k1 = 0.25 kg of plant-1; k2 = 0.5 kg of plant-1. The variables observed included: (1) Arenaceous plants: increase in caudal circumference, increase in the fifth midrib length, increase in the number of midribs, increase in number of leaflets on the fifth midrib and (2) Cocoa plants: increase in plant height, increase in stem circumference, the number of cocoa fruits, the intensity of pest and disease attacks on cocoa fruit. Observations on each variable were carried out at 3 and 6 months after treatment (mat). Data were analyzed by variance and if there were significant differences, it was followed by the Smallest Significant Difference Test (LSD) at the level of 5%. The results of the SP-36 fertilizer treatment showed very significant differences in all observation variables in early maturing palm trees and aged 3 bsp and 6 bsp cacao plants. The treatment of SP-36 fertilizer at a dose of 0.5 kg plant-1 (p2) gave the best growth of early maturing sugar palm plant 6 in the increase of the fifth midrib length, increase in bulb circumference, increase the number of midribs and increase the number of leaflets on the fifth midrib - each 137.17 cm, 25.58 cm, 3.25 strands and 39.08 strands. Likewise in the age of 6 bsp cocoa plants SP-36 fertilizer with a dose of 0.5 kg plant-1 (p2) gave the best growth in plant height increase, increase in stem circumference and number of cocoa fruit, each 18.92 cm, 8.25 cm and 25.25 pieces. The treatment of KCl fertilizer and the interaction between SP-36 and KCl fertilizers showed no significant difference in all observation variables in early maturing and cacao plants. Observations of pest and disease attacks on cocoa fruit with the intensity of pest attacks 0.00-23.47% were included in the category of minor damage and the intensity of disease attacks 0.00-66.30% which fall into the category of moderate damage.

Abstract

The former coal mines experienced biological changes that caused biodiversity loss compared to natural ecosystems. Habitats decline dramatically when changes from natural ecosystems to open land occur. The frequency of land processing due to land reclamation activities has a major impact on soil organisms. Coal mining activities result in a decrease in the population of microorganisms and the activity of soil fauna, mainly due to changes in soil temperature, humidity, and the amount and quality of organic matter. This research was conducted for 1 (one) fiscal year. This research includes the making of microorganism solutions, Trichoderma enrichment, composting from market waste with bioactivator moles and trichoderma, incubating ex-coal mine land by utilizing compost, and analyzing the total population of soil microorganisms. The results showed that 1. There was an increase in the population of microorganisms in the soil that were applied to market waste compost, 2. Mushrooms found on ex-coal mine land that were applied with market waste compost with Trichoderma bioactivator, and banana weed MOL were: Aspergillus, Trichoderma, Fusarium, Mucor, Phytium, and Gliocladium, while the bacteria found were basil gram (-) Azotobacteraceae and cocci gram (-) Azotobacteraceae.

Abstract

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).

Abstract

Soybean is an important food crop after rice and corn. Soybean production in East Kalimantan based on the 2014 forecast rate is estimated at 1,263 tons of dry seeds. Compared to 2013 production (ATAP 2013) there was a decrease of 139 tons (9.91%) (BPS, 2014). The low productivity is because the technique of managing soybean plants is still not optimal. Efforts to increase soybean productivity can be done by conducting intensive cultivation techniques. One of the cultivation techniques that can be done is by technical methods, namely crop trimming and intensive agricultural cultivation can be done in various ways including fertilization. The study was carried out for 5 months, namely from January to May 2018. The research site was on experimental land owned by the Faculty of Agriculture, Widya Gama Mahakam Samarinda. This study used a Randomized Block Design (RBD) with a 2 x 3 factorial experiment consisting of 3 replications. The first factor is Pruning which consists of 2 levels: namely p0 (without pruning), p1 (vegetative phase V4 pruning). The second factor is the dose of Solid fertilizer consists of 3 levels, namely s0 (without fertilization), s1 (5 kg / plot), s2 (10 kg / plot). The results showed that the pruning (P) treatment had a significant effect on the parameters of the number of productive branches and had no significant effect on height, flowering age, number of pods, weight of 100 seeds, weight of crop seeds and weight of mapped seeds. While giving Solid (S) fertilizer does not significantly affect all parameters. But the interaction of the treatment of pruning and giving Solid (PS) significantly affected the parameters of the number of productive branches.
