Abstract

Citrus plants (Citrus sp.) are most plants that grow in Petungsewu Village, Dau District. The decreased productivity of citrus plants causes the availability of citrus plants also to decrease. This needs to be increased to meet citrus plants' needs. The influence of soil organic matter is the main factor causing a decrease in the productivity of citrus plants in Petungsewu Village, Dau District. Therefore, it is necessary to estimate soil organic matter using the NDVI vegetation density index to obtain adequate and efficient results. Reliability testing was also carried out to know the accuracy level of the estimates made. The research was conducted at the Citrus Plantation and Subtropical Fruit Research Institute in Petungsewu Village, Dau District, Malang Regency. Estimation of soil organic matter using the NDVI vegetation density index showed an accuracy rate of 81.1%. The results of the accuracy analysis were strengthened by the presence of a paired t-test with a value of t = 0.01 and a value of p = 0.991.

Abstract

Oil palm fronds are waste products of oil palm plantations that are not utilized, yet oil palm fronds can be converted to biochar to improve soil fertility. This study aimed to analyze the chemical properties of the biochar generated from oil palm fronds. A pot experiment was conducted in Negeri Lama Seberang Village, Labuhanbatu District, Rantauprapat. The biochar formulation consisted of two formulations, i.e., A = pure biochar  (biochar in its original form) and B = granule biochar (biochar + tapioca flour). Each biochar form was repeated five times to obtain ten samples. The results of biochar laboratory analysis were continued with statistical tests based on the dependent t-test at the 5% level using Microsoft Excel. The results showed that biochar granules had chemical characteristics such as organic C of 32.78%, N of 2.39%, P of  0.18, K of 0.75%, and pH of 8.07. These values showed that granule biochar has better chemical characteristics than pure biochar.

Abstract

Organic agriculture must be applied in an integrated manner, from upstream to downstream, forming a system. This subsystem is part of the market-oriented agribusiness concept by paying attention to quantity, quality, and continuity to gain income and agricultural productivity profits. This study aimed to look at the development of organic rice farming in the Serdang Bedagai Regency from a regional (spatial), agribusiness, and economic point of view. ANN analysis involves distance variables between agribusiness subsystems, road infrastructure, and transportation. The results of the analysis showed that the spatial pattern of organic rice formed in the Serdang Bedagai Regency was distributed, especially in Lubuk Bayas Village and Tanah Merah Village, with each having a value of R = 2.81 (R> 1) and R = 6.15 (R>1). Pematang Setrak Village had a clustered spatial pattern or had a value of R = 0.12 (R<1). This shows that the closer the locations between the subsystems are, the more profitable it is, thus saving production and transportation costs. The gains obtained were strengthened by the results of the R/C ratio produced, namely Tanah Merah Village with a value of 1.36, Lubuk Bayas Village with a value of 1.39, and Pematang Setrak Village with a value of 1.48. This means that farming activities are pretty efficient.

Abstract

Appropriate fertilization recommendations are needed to maximize the production of oil palm plants on land that has been used for a long time. This study aimed to determine the status of soil fertility during the oil palm replanting period in Kemang Manis Village, Muara Papalik Sub-district, West Tanjung Jabung Regency, and determine fertilization recommendations according to the needs of oil palm plants based on soil fertility. This study used a survey method; soil samples taken were disturbed soil samples, and sampling was carried out at two depths, namely 0-30 cm and 30-60 cm. Determination of sampling points using stratified random sampling method based on homogeneous land units that were processed based on soil type and slope in the research location. The collected soil samples were analyzed for H, CEC, BS, organic C, P2O5, K2O, and total N. The results showed low fertility status during the oil palm replanting period in the research location. Observations of the soil profile also showed that the O horizon was thin. Fertilization recommendations that must be made to improve soil fertility include adding dolomite fertilizer to increase soil pH value and increasing the availability of N, P, and K elements in the form of Urea, SP36, and KCl. To increase the content of organic materials in the soil, applying oil palm empty fruit bunches can also improve the soil's physical, chemical, and biological properties.

Abstract

Optimizing land use plans is carried out for land capabilities that are useful for conserving land resources so that they can reduce the problem of land degradation. This study aimed to assess the level of land capacity and determine the function of both protected and cultivated areas in Development Area Units (SWP). The method used in the research is quantitative descriptive, consisting of data collection and processing stages. Data collection was carried out through literature studies from several related agencies. Meanwhile, spatial data analysis was carried out using Geographic Information System (GIS) software. The results of the research showed that the analysis of land capacity, especially for determining the function of areas for settlement, reached 3,687.35 ha and the buffer area was around 11,755.27 ha. This indicates that only a small portion of suitable areas can be developed for urban development. This is due to the physical limiting factors of the land where the characteristics of the Ambon City area are dominated by hilly areas.

Abstract

Inceptisols dominate Indonesia's land area; therefore, future utilization needs to be maximized, especially land that has undergone extensive tillage continuously. Inceptisols have low levels of essential nutrients, especially nitrogen, phosphorus, and potassium. One of the efforts that can be made to improve nutrient content is the application of compost. This study aimed to investigate the effect of compost combined with mycorrhiza on total N, available P, exchangeable K, and soil organic C, as well as the growth and yield of sweet corn. The experimental design used in this study was a completely randomized design consisting of five treatments with three replications. Each observation parameter was analyzed using the F test at the 5% level. Parameters that significantly affected the F test were followed by the DMRT test at the 5% level. All observed data were tested for correlation using SPSS V24 to see the relationship between observation parameters. The results showed that the application of a combination of compost and mycorrhizae increased total N content by 78.7%, available P by 26.6%, soil organic C by 29.54%, plant height by 143.87cm, number of leaves by 11.33 leaves,  and cob weight by 294.33 g compared to control. The correlation test showed that applying a combination of compost and mycorrhiza affected N in the soil, so the growth and yield of corn were higher.

Abstract

This study aimed to assess the impact of combinations of varying soil amendments and water amounts on the leaching water requirement for cucumber growth and production. Saline soil was collected from Banongan, Situbondo, with soil electrical conductivity (EC) of 4-6 dS m-1. A 10 kg soil sifted with a diameter of 2 mm was placed in each mini lysimeter. Leaching was carried out until the soil EC reached below 2 dS m-1. The results showed that soil leaching reduced soil EC from 5 dS m-1 to 1.6-1.8 dS m-1; meanwhile, EC in leachate ranged from 2-2.3 dS m-1. Biochar treatment caused an increase in leaching water requirements. In addition, applying biochar combined with 40 mm day-1 of water produced the highest fruit number. The combination treatment of cow manure 100 g pot-1 (equivalent to 20 t ha-1) and biochar 30 g pot-1 (equivalent to 6 t ha-1) and adding 40 mm day-1 of water during each water application produced the most prominent fruit volume. Furthermore, utilizing 40 mm day-1 of leaching water produced the best number of leaves, fruit weight, length, and fruit circumference.

Abstract

Part of the dry land in Madura developed from parent material, namely sand sediments which have a low organic matter content. This study aimed to determine differences in the effectiveness of corn seed coating materials from bentonite, biochar, lignite, and biochar compost on the growth and yield of maize (Zea mays L.) under drought stress conditions. This study was conducted at the Integrated Laboratory and screen house of the Faculty of Agriculture, University of Jember, using a completely randomized design. The treatments tested in this study comprised two factors. The first factor was the treatment of coating materials, namely C0 = without coating (control), C1 = bentonite coating, C2 = biochar coating, C3 = lignite coal coating, and C4 = biochar compost coating. The second factor is the level of drought stress, namely K0 = control (100% KL moisture), K1 = Light stress (80% KL moisture), K2 = moderate stress (60% KL moisture), and K3 = severe stress (40% KL moisture). The results showed that the combination of seed coating agent treatment and drought stress had a significant effect on the parameters of plant height, number of leaves, leaf area, age of male and female flowers, cob length, cob diameter without husks, biomass dry weight, and production potential per hectare. The coal coating material and light drought stress 80% KL (C3K1) was the best combination of seed coating and drought stress treatment.

Abstract

Maize is the main strategic food crop in Indonesia's food supply, but the productivity of maize in Indonesia is still low. Increasing the productivity of maize can be done by understanding information about the characteristics of the soil on maize planting areas. The research aimed to evaluate the relationship of soil biological and chemical characteristics (available P, phosphate solubilizing bacterial population, arbuscular mycorrhizal fungal population, organic C, and cation exchange capacity) on maize plant productivity. The research was carried out in Cibugel District, Sumedang Regency. The research used descriptive survey and comparative methods on 18 soil samples. The maize planting area was obtained based on analysis and overlapping of land units in the form of; slope, elevation, climate and shelled maize production area. Maize planting land is at an altitude of 500-1,000 meters above sea level and with a slope of 10-30%. The results of correlation analysis showed that organic C, cation exchange capacity, and phosphate solubilizing bacteria had a positive correlation with maize productivity, while available P and arbuscular mycorrhizal fungi had a negative correlation. organic C had the highest close relationship with a value of r = 0.43, while the other parameters have a weak relationship.

Abstract

Drought stress and acid soil pH are a form of abiotic stress on acid-dry land. Actinomycetes are a group of transitional microbes that have benefits as bioprotectants, biostimulators, and biofertilizers. This study aimed to determine the optimum growth environment for Actinomycetes at various incubation temperatures (25, 30, 35, and 40 ℃) and media pH (5, 6, 7, 8, and 9) and prove its effectiveness on mustard plants when given drought stress, and increase in acid soil pH. The research was conducted in the LOB greenhouse of PT Great Giant Pineapple using two factors, namely Actinomycetes (F22, F26, F34, F39, and F47) and irrigation (watered and not watered). Observations included Actinomycetes population (CFU mL-1), plant response (percentage of stress, death, survival, recovery), plant growth (plant length, number of leaves, root length), plant production (fresh weight), soil pH, and soil organic matter. Results of this study showed that Actinomycetes F22 gave the highest total population (107 CFU mL-1), and the P4K1, P4K2, and P2K2 treatment combination gave the best results on the observed parameters.
