Abstract

The phenomenon of land conversion of natural forest into agricultural cultivation is an event in nature that must be understood to determine action in the future. The aim of this research was to know the influence of land use changes to soil erosion and sediment transported. Simulation on hydrological model was used as research method. Soil Water Assessment Tool (SWAT) Hydrological models that have been validated on a very good level based on the Nash-Sutcliffe Efficiency (NSE), is used to simulate in land use changes, based on Land Cover Index Changes (IPL) permanent and production scenarios, on soil erosion (SYLD) and sediment transported (Sed-out), in 101,027.250 hectares of the upstream of Mrica reservoir catchment area. SWAT model simulation results indicate that quantitatively, the increase IPL permanent followed by a decrease in IPL production has the potential to lower the value of soil erosion ton/hectares/year) of approximately 5.77% to 82.37% and from 5.15% to 75.12% of sedimentary transported (mm/year). Qualitatively, positive Extreme scenario, can increase the value of soil erosion in some sub-catchments and the upstream of Mrica reservoir catchment area, from worse quality on the existing condition become moderate, and even good. Watershed management efforts to reduce the rate of soil erosion and sediment transported on the river, with land use changes should be followed by soil and water conservation techniques such as bench terraces and contouring.

Abstract

The negative impact of prolong and excessive application of synthetic fertilizers is a reason to reuse organic material as a plant nutrition resources and to enhance degraded soil. Organic materials such as animal and industrial wastes are commonly use as sources of organic amendment. The purpose of this study was to examine the changes in chemical properties of soil and the growth of sweet corn as affected by the application of solid organic fertilizers in Ultisol. This research was carried out in October 2016 until March 2017 at Greenhouse, University of Bengkulu, arranging in a Completely Randomized Design with two factors and three replications. The first factor was Organic amendment consisting of vermicompost, chicken manure, oil palm empty bunches compost (OPEBC). The second factors were rates of the amendment, i.e., 0, 10, 20, and 30 Mg ha-1. Results indicate that total soil organic carbon (TSOC) and total soil nitrogen (TSN) were not considerably different among types of organic amendments used in this study; however, an increase in soil pH and a decline of exchangeable Al are highest in the application of OPEBC as compared to others. Likewise, the growth of sweet corn was the best in soil amended with chicken manure. Soil chemical properties such as TSOC, TSN, soil pH significantly enhanced but exchangeable Al markedly lowered up to 20 Mg ha-1, then level off afterward. Sweet corn growth as indicated by plant height, shoot dry weight (SDW), and root dry weight (RDW) was also significant up to 20 Mg ha-1. This study suggests that the addition of organic amendment at a rate of 20 Mg ha-1 is sufficient to provide plant nutrient and improvement of soil properties for sweet corn growth.

Abstract

Mustard is one type of leaf vegetable favored by the community because it tastes fresh and contains lots of vitamins A, B, and a little vitamin C. The large area of peatlands in Indonesia and the lack of mineral soils that can be used as agricultural land, make peatland use necessary. Peat is used for agricultural development, with the main limiting factor for growing media conditions that are not conducive to root development, especially land conditions that are saturated with water, react with acid, and contain organic acids at levels that can poison plants, so that some reclamation measures are needed for the land condition peat becomes more suitable for plant development. This study aims to determine the response to the concentration of liquid organic fertilizer (LOF)  and its interaction on the growth of mustard greens (Brassica juncea L.) in peatlands. This research was conducted from April to May 2018 using a completely randomized design (CRD). The treatment given was a dose of LOF consisting of 0; 500; 1000; 1500; 2000 and 2500 L/ha. The variables observed included soil pH, plant height, number of leaves, above-ground fresh weight, below ground fresh weight, above-ground dry weight, and below-ground dry weight. The results of this study indicate that dosing of LOF has a significant effect on plant height, above-ground fresh weight, and above-ground dry weight. However, it did not have a significant effect on soil pH, leaf number, and below ground fresh weight and ground dry weight. The application of the highest LOF at 2500 L/ha was able to increase plant height by an average of 7.75 cm.

Abstract

Cucumber is one of popular vegetables among consumers and widely cultivated by in Indonesia. Since there is an increasing concern of fertilizer costs and sustainability of land resources, the use of synthetic fertilizer must be minimized by using more organic sources, including the use of waste of fruit bunch of palm oil as compost. This experiment aimed to determine the best combination of between palm-oil fruit bunch organic fertilizer and synthetic nitrogen on cucumber yields. Treatments were consisted of (1) without palm-oil bunch organic fertilizer + without Urea, (2) without palm-oil bunch organic fertilizer + Urea 50 kg ha-1 , (3) without palm-oil bunch organic fertilizer + Urea 150 kg ha-1 , (4) without palm-oil bunch organic fertilizer + Urea 250 kg ha-1 , (5) palm-oil bunch organic fertilizer 5 tons ha-1 + without Urea, (6) organic fertilizer palm-oil bunch 5 tons ha-1 + Urea 50 kg ha-1 , (7) palm-oil bunch organic fertilizer 5 tons ha-1 + Urea 150 kg ha-1 , (8) palm-oil bunch organic fertilizer 5 tons ha-1 + Urea 250 kg ha-1 , (9) palm-oil bunch palm-oil bunch organic fertilizer 10 tons ha-1 + without Urea, (10) palm-oil bunch organic fertilizer 10 tons ha-1 + Urea 50 kg ha-1 , (10) palm-oil bunch organic fertilizer 10 tons ha-1 + Urea 150 kg ha1 , (12) palm-oil bunch organic fertilizer 10 tons ha-1 + Urea 250 kg ha-1 . Results indicated that combination application between palm-oil fruit bunch organic fertilizer and synthetic nitrogen significantly effects fruit length, fruit diameter, number of fruit planted, fruit weight per plot, number of fruit per plot and fruit weight per plot. It was concluded that the use of 10 tons ha-1 of palm-oil bunch organic fertilizer in combination with 250 kg ha-1 of Urea (P12) was the best treatment combination to increase cucumber yields.

Abstract

The development of oil palm plantations in Indonesia as a commodity crop has increased rapidly from year to year. The oil palm plant in Pondok Kelapa District, Middle Bengkulu Regency is the second-largest plantation of people after oil palm. Increasing the income and welfare of farmers can also be done through the evaluation of peatland custom in oil palm crops. This study aims to evaluate the suitability and analyze peatland limiting factors for oil palm plants in Pondok Kelapa District and provide peatland processing direction based on limiting factors to produce palm oil production in Pondok Kelapa District. This research was conducted in Pondok Kelapa Bengkulu Tengah Regency from December 2014 until January 2015 through 4 stages, namely pre-survey, field survey, data analysis, and making a map of the potential development of oil palm plantations. The results showed that each observation point has a low to moderate soil fertility rate It is characterized by low pH and N total values, as well as low P2O5 in providing nutrients for oil palm plants. In general, limiting factors are the dominant limiting factors, namely available nutrients (P2O5, N total) and nutrient retention (pH). The results of land suitability evaluation in Pondok Kelapa District showed the land suitability class is S2 and S3, actual land suitability class for oil palm plants in Pondok Kelapa District with barrier factors hampered drainage, fertility/low soil nutrients, and soil drainage is very hampered/very bad. Efforts to increase peatland potential for oil palm crops can be done by improving drainage, planting systems, and high maintenance of groundwater levels in oil palm plants.
