Abstract

The rhizosphere is an excellent habitat for microbial growth because plant roots provide a variety of organic materials that generally stimulate microbial growth. This study aimed to explore and determine the character of fungi from oil palm rhizosphere (Elaeis guneensis Jacq) on smallholder plantations in Kuantan Singingi Regency. This research was conducted at the Islamic University of Kuantan Singingi. The method used was an experimental method carried out in two stages. The first stage was a random sampling survey. The sample was then taken to the Basic Laboratory of the Faculty of Agriculture, Kuantan Singingi Islamic University for analysis. They are Singingi Hilir District, Kuantan Mudik District, Kuantan Tengah District, Benai District, Pangean District and Sintajo Raya District. The most isolates were found in Singingi Hilir sub-district, the plant age was 2 years and the fertile soil was blackish brown. The least number of isolates was found at the age of 10 years, even though the soil was fertile. The age of the plant affected the microbial activity in the rhizosphere. The older the plant the microbial activity decreased. Therefore, it caused the number of isolates found to be small. Characteristics of isolates isolated at a younger plant age were more varied in color.

Abstract

The purpose of this study was to analyze the nutrient content of POC produced from household waste using the stacked bucket method. This research was conducted for 3 months from September to November 2020. This research is a descriptive study. The first process is the process of making organic fertilizer from household waste which is fermented in a stacked bucket for 2 months. Leachate from organic waste is dried in the sun for one month or until the leachate is blackish in color and has no more subtle aroma. The finished POC is sampled and tested in the laboratory to determine the content of micro and macro nutrients as well as organic C. To measure the content of macro and micro nutrients, the test material used was Kjeldahl for nitrogen content while P, K, Fe, Mn, Cu, Zn, S, Ca, Mg, Na used spectrometric wet oxidation method and the content of C-organic by spectrophotometric method. The test results showed that the POC of household waste contained 0.08% total N, 0.07% total P, 0.28% total K, 5 ppm total Fe, 0.4 ppm total Mn, 0.0 ppm total Cu, Zn total 0.6 ppm, total S 0.5%, total Ca 165.0 ppm, total Mg 106.9 ppm, total Na 172.7 ppm, organic C 1.06%, and C/N ratio 13.27.

Abstract

The development of technology in agriculture is currently speedy, with innovations that can increase the production and quality of agricultural products. Supporting the hydroponic cultivation system's success is by applying porous and well-aerated media and the availability of sufficient nutrients for plant growth and plant production. The availability of Rockwool is difficult to obtain in the 50 Kota Regency. It needs to utilize local potential as a planting medium alternative, such as using bricks and husk charcoal. The research was conducted in a completely randomized design with three replications. The treatments tested for the composition of the growing media using the Drip flow technique (DFT) system included: Rockwool, Husk Charcoal (50%) + Bricks (50%), Husk Charcoal (25%) + Bricks (75%). Based on the results and discussion of the analysis previously described, the conclusions obtained from the research that has been carried out are as follows: Treatment of the use of various types of growing media on the observation of growth and production of hydroponic Pakcoy plants gives significantly different results on the observation variables of leaf length, leaf width, and the number of leaves and plant total wet weight.

Abstract

The decline in production of cabbage in Indonesia is due to the lack of intensive and traditional cultivation of this plant, ie without the use of spacing and frequency that is not appropriate, resulting in a seizure of nutrients from the soil by plants and organ cover of the cabbage plant itself which inhibits the photosynthesis process. So this research was conducted to know the effect of effective spacing that can increase the growth and production of cabbage plants. This study used a single factor randomized block design consisting of 4 levels of treatment, namely 1) Without Planting Distance; 2) Planting distance 35 cm x 35 cm; 3) Distance to plant 45 cm x 45 cm; and 4) Planting distance 55 cm x 55 cm. Each treatment was repeated 3 times to obtain 12 experimental units. The plant spacing factor on cabbage had a significant effect on the observation of plant height, the number of leaves, and leaf length. While the results of observations on the fresh weight of cabbage buds did not have a significant effect on the spacing treatment. The planting distance at 25cm x 55cm gave the best effect on the growth and production of cabbage (Brassica oleraceae L.).

Abstract

Due to the extreme weather that hit throughout the year resulted in the threat of rice plants falling down. It was known that the fall of rice plants was a limiting factor for obtaining high yields and quality of grain. Therefore, it was considered important to evaluate the resistance to fall in the general methods of planting rice in the area. Those were transplanting planting (TP) and direct seed planting (TBL). Based on this objective, we identified the morphophysiology of rice stems in the laying factor of 2 planting methods commonly used by farming communities, namely transplanting planting and direct seed planting. Identification was carried out by observing the morphology and physiology of the rice stalks, the laying index and the level of fall of rice plants in each planting method (TP and TBL). The result of the research was that the direct seed planting method (TBL) tends to show morphophysiological identification results that were not resistant to falling compared to the transplanting method (TP). The laying rate shown by TBL was accounting for 75.5% while transplanting (TP) was only 5.7% of the experimental unit area. Significant differences were observed in plant height, stem length, center of gravity height, laying index, laying level, stem internode length, stem internode width, bending moment and bending stress of the stem. In the experiment, it was also found that the grain was damaged due to the fall of the rice plant when the rice fields were flooded. Therefore, it is important to carry out agronomic management as part of sustainable mitigation of the risk of falling rice plants to support national food security
