Abstract

The main problem of upland rice cultivation is the presence of weeds, which cause a decrease in the quantity and quality of crop yields. Generally, farmers use synthetic herbicides to control weeds. One way to reduce the use of synthetic herbicides is by using kiambang extract bioherbicides which are applied to weeds. Currently, there is no research to determine the effect of kiambang extract on upland rice germination. The purpose of this study was to assess the effect of kiambang bioherbicide on the germination phase of upland rice by giving several concentrations of kiambang bioherbicide. This study used a completely randomized design (CRD) with 5 concentration treatments, namely 2,4-D herbicide, 20%, 40%, 60%, and 80% bioherbicide. Kiambang extract concentration was repeated 3 applicates for each replication; each experimental unit consisted of three Petri dishes containing 25 rice seeds. The research parameters were germination percentage, germination rate, length of the plumule, and radicle. Observational data were analyzed using analysis of variance (F test) at a level of 5% and continued with the Least Significance Different (LSD) test at a level of 5% to determine the difference between treatments. The results showed that the bioherbicide extract of kiambang (Salvinia molesta) 20% did not inhibit seed germination, but the seeds grew abnormally, while concentrations of 40%, 60%, and 80% inhibited germination.

Abstract

Unrecycled mushroom Baglog waste will become a place for spores to grow so that the spores will spread to the inoculation room, damaging the mushroom Baglog media, which causes crop failure. The right step for utilizing Baglog waste is composting it. A composted Baglog waste will be better if it is added with arbuscular mycorrhizal fungi (FMA), improving and increasing soil nutrient quality. This study aimed to determine the potential of mushroom Baglog waste compost by adding FMA to groundwater spinach growth (Ipomoea reptans Poir). This study used RAK to treat compost, compost+AFM 10g, compost+AFMA 20g, and compost+AFMA 30g. The study results indicate that Baglog waste compost and FMA have not been able to interact well on the parameters of tendril length, wet weight, and dry weight, as shown by the results that are not significantly different from compost treatment without FMA. Even so, compost waste has the potential to be used as fertilizer or media because it already has physical quality conforming to SNI. Adding FMA to mushroom Baglog waste compost is recommended because it can potentially increase plants' growth rate. The best interaction between Baglog mushroom waste compost and FMA was the compost + 10 g FMA treatment for all observation parameters.

Abstract

Oil palm is a plant greedy for water and nutrients that can ultimately reduce soil conditions both from water and nutrients in the soil; for this reason, it is necessary to improve soil conditions. The application of EFB can be one of the solutions to overcoming the problem. This study aims to determine the Influence of Empty Fruit Bunch on improving the Chemical Properties Of Soil Planted By Oil Palm At Supra Matra Abadi Aek Nabara Estate. This research was conducted at Afdeling III Supra Matra AbadiAek Nabara Estate. This research was conducted for five months. This research method used a Factorial Randomized Block Design (RBD), which consisted of 2 factors. The first factor was soil depth which consisted of 0-15 cm, 15-30 cm, 30- 60 cm, and 60-90 cm. The second factor is the application of empty fruit bunches, which consists of no EFB application (control) and the application of empty fruit bunches: 370 kg/tree. The results showed that giving empty fruit bunches to oil palm plantations can increase soil fertility. The application of EFB affects the pH values of the soil, Potassium, Magnesium, and Calcium. And the depth of the ground, given the application of EFB, negatively affects soil fertility. This means that if the soil's depth increases, soil fertility tends to decrease as well as it should.

Abstract

Soil quality is a useful concept when assessing the sustainability of an agricultural business and demonstrating the ability of soil to maintain plant and animal productivity, improve water and air quality, and protect human health. SQI is a soil variable with the following characteristics: 1) well correlated with ecosystem processes; 2) integration of physical, chemical, and biological soil properties; 3) good sensitivity to human-induced soil changes; 4) simple measurement and interpretation; and 5) Reproducibility Soil quality index (SQI) is a diagnostic procedure to evaluate soil function and overall health. This research was carried out on a unit of land in a dry area in Aceh Besar District with a study area of 239,439.63 ha. Analysis of biomass samples and soil samples was carried out at the Laboratory of Soil and Plant Sciences and Soil Physics Laboratory, Faculty of Agriculture, University of Syiah Kuala. The tools used in this study include a set of computers with the Microsoft Windows 10 operating system that are equipped with several software for analysis, writing instruments, and other supporting tools. The main materials used in this study were soil samples, tree diameter measurement data, and land use maps, including geology, climate, slope class, soil, and topography. The results of the correlation analysis test showed a value of 0.6358. This shows that the relationship between soil C potential and soil quality index is a strong correlation. The distribution of carbon in the soil also has a close relationship with the soil quality index and is an effort to maintain carbon stocks in the soil. C - organic content is a very important parameter in compiling soil quality index criteria. Soil quality can be affected by many factors, such as parent material, environmental factors, land use type, and human activities. The percentage of soil organic C is an indicator of the percentage of soil organic matter (BOT), and BOT is able to improve soil structure and aggregates. Soil organic carbon (SOC) concentration is closely related to soil quality and vegetation productivity. This relationship occurs because of the many contributions of soil carbon to soil properties such as the improvement of soil structure and water retention, provision of cation exchange capacity, and supply of plant nutrients through mineralization. This effect is especially important in small-scale tropical farming systems where the use of external inputs is often limited, and SOC concentrations have been positively correlated with yield levels for a variety of tropical soils.

Abstract

This study aims to determine the extent to which rainfall affects soil subsidence on peatlands in PT. BGA. TBk., Pundu, Central Kalimantan. The research was conducted at Katari Estate, PT BGA, Tbk. Pundu Central Kalimantan in September - December 2019. The research method used is the survey method, which consists of two stages, namely the preliminary survey and the main survey. A preliminary survey was conducted to determine the research location while the main survey was carried out to obtain research data, namely monthly rainfall data and subdidence in 2014 – 2018. To see the relationship between rainfall and land subsidence, Linear and Polynomial Regressions were made at lag 1, lag 2, and lag 3. Regression with lag 1 is the relationship between rainfall last year with land subsidence this year and rainfall last month with land subsidence on peatlands this month in the same year, and so on for lag 2 and lag 3. The results show that the regression between The best rainfall with soil subsidence on peatlands is the annual Lag 1 Linear Regression. This means that last year's rainfall has an effect on this year's subsidence. with the equation, Y = - 0.004 X + 1.209, where R² = 0.582. This equation is obtained from the correlation between X (average rainfall) from 2015-2018 and Y is soil subsidence also from 2015-2018. While the regression between last month's rainfall and this month's land subsidence in each year (2015 – 2018), shows a low correlation.

Abstract

Many different kinds of plants, including coffee plants, are susceptible to disease. In Cangkringan, Sleman, Yogyakarta, this study aims to discover diseases. Compute the percentage of disease attacks, and determine the causes of diseases that affect coffee plants. The Central Laboratory of the Yogyakarta Institute campus is located in the Sleman Regency's Maguwoharjo District. The sample took place in the hamlets of Kopeng, Petung, and Gondang Pusung in the Cangkringan District, D.I. Yogyakarta. The research was done between March and September of 2021. The survey, collection, and identification of fungi that cause coffee plant illnesses in the field and laboratory were the research techniques used. Additionally, farmers who work on coffee plantations were interviewed. Descriptive analysis was done on observational data related to illness symptoms. According to data on environmental conditions in the three coffee plantations, Petung Hamlet had the highest elevation (875.7 masl), Kopeng Hamlet and Gondang Pusung Hamlet had the highest air temperature (27.9 °C), Gondang Pusung Hamlet had the highest air humidity (75%), Kopeng Hamlet had the highest irradiation intensity (1947 Lux), and the three hamlets' soil pH ranged from 5.5-7. A quantitative analysis of the illness attack rate was performed. On the macro- and micro-morphological characteristics of mushrooms, qualitative analysis was conducted. The findings revealed that fungi were to blame for four different types of coffee plant illnesses. These illnesses include sooty mildew, leaf spot, scurvy, and leaf rust (all caused by the fungus H. vastatrix) (Capnodium sp.). Kopeng Hamlet had the highest incidence of disease attacks, including 9.7% for leaf rust, 11.8% for leaf spots, 4.8% for black fungus, and 2.9% for sooty mildew.

Abstract

Through the use of low dosages of chemical fertilizers and effective nutrient-corn genotypes that respond to bio-fertilizer type assignments, this study intends to produce rather steady outcomes over the course of several growing seasons. Field tests for this study have been conducted at the ATP Ministry of Research and Technology in South Sumatra. The experiment was run across two growing seasons: the dry season (May through September 2011) and the rainy season (January–April 2012). The equal split-split plot design is used for the study's two growing seasons. The central conflict concerns the application of chemical fertilizer at the following rates: P1: 50% standard dose of ATP (200 kg urea, 50 kg SP36, and 25 kg KCl ha-1), and P2: 25% standard dose of ATP (100 kg urea, 25 kg SP36, and 12,5 kg KCl ha-1). Treatment of several biological fertilizer subplots: H0: no biological fertilizer (control); H1: mycorrhiza; H2: bacterial phosphate solvent. The treatment of children plot uses a variety of corn strains with effective nutrient selection outcomes, including strains B41 (G1), L164 (G2), S219 (G3), and variations BISI 816, as the genotype comparison (G4). Three times each was used for each combination of treatments. The results of the two investigations indicate that strain B41 can produce adaptive growth based on the growing season, is more resilient to drought stress, and may be able to produce more at lower doses of chemical fertilizer while being comparatively stable. A combination of chemical fertilizer at the 50% standard dose of ATP and mycorrhizal fertilizer, along with strain B41, has the best impact on the growth and yield of maize on marginal dryland. Mycorrhizae fertilizer at various levels of low doses of chemical fertilizer can increase the growth and yield of maize in two different cropping seasons. All of the examined maize lines generally showed the ability of the bacteria connected to mycorrhizal and phosphate solvents to enhance nutrient absorption

Abstract

Non-cultivated local rice is known to have high resistance to various environmental stresses. This resistance is inseparable from the role of symbiotic and non-symbiotic rhizosphere bacteria that live in the root rhizosphere. This study aims to isolate and study the potential of rhizobacteria that live around the roots of non-cultivated local rice plants. This research is exploratory research to obtain rhizobacterial isolates that can stimulate plant growth and development and can be applied to cultivated rice plants. Soil samples were taken from Mimi Baru Village, Jagebob District. Sampling was carried out aseptically. Isolation was carried out using the multilevel dilution method. Isolates grown in NA media were then subcultured to obtain pure isolates. The isolates obtained were then characterized morphologically according to Bergey's Manual of Determinative Bacteriology and characterized microscopically. Based on the results of this study it can be concluded that there were 12 bacterial isolates in the local rice "Cempo Laut" which were suspected to be Bacillus and Pseudomonas. The results of this study need to be tested further to determine the effect on plant growth and development.

Abstract

The study's full title was "The Effect of Application Intervals of Different Types of Insecticides in Controlling Fruit Fly (Bactrocera sp.) Pests on Production of Curly Red Chili (Capsicum annum L.)." From July 2021 to October 2021, it was conducted in the dormitory area of the Riau Islamic University. The goal of this study was to ascertain how different vegetable insecticide kinds interacted with treatment intervals to control fruit fly pests and curly red chili plant production. This study employed a two-factor, entirely randomized design. The first factor was a combination of four different doses of pesticides, including isoprocarb 2 g/l, betel leaf extract 100 cc/l, neem leaf extract 100 cc/l, and lime leaf extract 100 cc/l. The application time interval, which has four levels—3 days, 6 days, 9 days, and 12 days—is the second element. 48 experimental units were created by combining 16 treatment combinations, each of which had three replications. There were 192 plants total because there were 4 plants per experimental unit and 2 plants were used as samples. The data is statistically analyzed before being subjected to the BNJ test. The outcomes demonstrated that not all parameters were affected by interactions and combinations of application intervals and different insecticide types, including the percentage of flowers to fruit, age at first harvest, fruit weight per plant, fruit weight per fruit, percentage of fruit flies attacked, other types of pests that attack, and age of disease across all treatments.
