Abstract

Inefficient fertilization is the cause of decreased rice production. This is due to the inappropriate use of fertilizers. The absence of information on soil nitrogen content in their area causes farmers not to apply fertilizer properly. Analysis of soil nitrogen content in Pamekasan Regency requires much time, cost, and effort. Remote sensing methods can be used to obtain information on soil nitrogen levels by reducing the number of samples used. This study aims to estimate nitrogen content in rice fields using the vegetation index in the form of NGRDI (Normalized Green Red Difference Index). This research was conducted by purposive random sampling method based on 40 land map units formed in Pamekasan Regency, laboratory analysis, statistical analysis, and making distribution maps. The results showed that there was a significant relationship between the NGRDI pixel value and the nitrogen content, with a correlation value of -0.42. The regression equation results obtained from the NGRDI value with nitrogen content are y = -0.269x + 0.139. The accuracy test was carried out by the RMSE method, and the result was 0.027. This shows that the NGRDI index can estimate soil nitrogen content in Pamekasan Regency

Abstract

This study aimed to assess the erosion hazard level in the Wairutung Watershed. The land unit in this study was generated from the overlaying land use maps, slope maps, and soil types maps.  The class of vulnerability was determined based on the sum of the parameters' rating results using a computer-based Geographic Information System (GIS) with the ArcGIS program, which was integrated with the Universal Soil Loss Equation (USLE) model. The results indicated the division of 4 classes of landslide hazards consisting of a very light class with an area of ​​2,900.865 ha spread over land units with alluvial soil types. The medium type, with a total area of ​​3,683.285 ha, is spread over land units with podzolic soil types. Heavy type with a total area of ​​1,458.367 ha and the whole area is spread over land units with podzolic and Litosol soil types. The erosion hazard level is very heavy, with a total area of ​​421.97 ha and is spread over land units with Podzolic and Litosol soil types.

Abstract

Nitrogen is a primary macro nutrient needed by plants and has an important role in plant growth. Regosols, Latosols, and Grumusols are soils that have the potential as a medium for plant growth, with different characteristics and levels of productivity and are constrained by soil nitrogen. Application of nitrogen-rich vermicompost as an alternative to overcome the problem of the three soils. The research aimed to determine the available nitrogen content and nitrogen absorption of pakcoy by adding vermicompost on Regosols, Latosols, and Grumusols. The research used a split-plot design with the main plot in the form of soil types (T1 = Regosols, T2 = Latosols, and T3 = Grumusols) and a subplot in the form of a dose of vermicompost fertilizer (K0 = 0 t ha-1, K1 = 10 t ha-1, K2 = 20 t ha-1, and K3 = 30 t ha-1) so there are 12 treatments and repeated three times. The results showed that the application of vermicompost to Regosols, Latosols, and Grumusols increased total N, available N, organic carbon, cation exchange capacity, plant height, fresh weight, dry weight, plant N, and plant N uptake. The dose of vermicompost 20 t ha-1 was the optimum dose for the parameter of N availability.

Abstract

Regosol has been widely used for agricultural production despite its low nutrient availability and adsorption. This research aimed to know the effects of bokashi and zeolite on the availability of nitrogen (N) in Regosol. The experiment was carried out with a completely randomized 2-factors design. The first factor was bokashi, with three levels: 0 t ha-1 (B0), 20 t ha-1 (B1), and 30 t ha-1 (B2). The second factor was zeolite with three levels: 0 t ha-1 (Z0), 5 t ha-1 (Z1), and 10 t ha-1 (Z2). Each treatment was repeated three times. Each treatment was incubated for 30 days. The parameters before being treated were texture, bulk density, pH H2O, N-totals, C-organic, available N, and CEC in soil, pH H2O, N-totals, available N, and C-organic in bokashi, also CEC in the zeolite. The parameters after being treated were pH H2O, N-totals, C-organic, C/N, available N, and CEC in soil, also leached NH4+ and leached NO3- in water. The data were analyzed with ANOVA followed by the DMRT at a 5% level. The results showed that bokashi significantly affected the available N, pH H2O, N-total, leached NO3-, and CEC, meanwhile zeolite did not significantly affect the available N but significantly affected the N-totals, C/N in soil, and leached NO3-. The combination of bokashi and zeolite did not significantly affect the available N in the soil. The best dose of bokashi increasing available N of Regosol was at a dose of 20 t ha-1 (B1).

Abstract

Human activities and global warming cause forest fires that impact increasing carbon emissions, destroy forest biodiversity and destroy soil properties. This research is needed to examine carbon storage and soil physical properties on various types of land cover in the Cempaka Forest area, which will later be used as a basis for carrying out restoration and conservation actions. This study used four observation points: Timber Forest Products, Non-Timber Forest Products, Pine, and Shrubs land cover. Carbon storage was measured in the Cempaka forest using the standard RaCSA procedure. The results showed that land cover differences significantly affect the value of carbon storage, with the highest value for storing carbon being the land cover of HHK. However, the difference in land cover did not cause different results on the physical properties of the soil. Correlation and simple regression between the value of carbon storage and other parameters show that carbon storage is strongly influenced by tree biomass and litter, with respective values ​​of 94% and 21%.

Abstract

Gold mining is closely related to land degradation caused by heavy metals such as lead (Pb), which are non-degradable, non-essential, and immobile. This study aims to compare soil lead levels before and after phytoremediation using local plants. Plant species consist of white teak (Gmelina arborea Roxb.) Pulai (Alstonia scholaris L.R.Br.), ganitri (Elaeocarpus ganitrus Roxb.), pine (Pinus merkusii Jungh), rasamala (Altingia excelsa N.) and puspa (Schima wallichii K.) with the planting position on the upper terrace, middle terrace and lower terrace. Soil characteristics observed were texture, spH, and lead content. The two-sample pair test (paired t-test) on the soil before and after phytoremediation had a significant effect on soil lead content (Sig. 1- tailed).

Abstract

Cukilan Village has a land area of 702.8 ha, with land use for agriculture covering an area of 620.2 ha. Agricultural land is widely used for fruit crops such as durian, rambutan and mango, but the production is considered not optimal, so it is necessary to evaluate the suitability of the land. This research was conducted to determine the characteristics of the Cukilan Village land; land suitability class for durian, rambutan and mango commodities; as well as land limiting factors. The research was carried out for 5 months and referred to the Technical Manual for Evaluation of Land Suitability for Agricultural Commodities with modifications to the determination of land suitability classes and limiting factors. The results of this study indicate that the land suitability class for durian and rambutan is moderately suitable (S2) with an area of 606.4 ha (97.8%) and marginally suitable (S3) with an area of 13.8 ha (2.2%). Land suitability class for mangoes is moderately suitable (S2). The limiting factors for durian, rambutan, and mango plants were rainfall, slope, drainage, KB, CEC, pH, and C-organic. Actions that can be taken to increase the productivity of these commodities are adding suitable organic matter, soil ameliorants such as lime and other materials containing CaCO3 and MgO3 and carrying out land management.

Abstract

High demand for shallots needs to be supported by an increase of yield in each region. The use of high-yield cultivar is one of the ways that can be done to increase the productivity of shallot conducted. Bangka has a soil of the Ultisol type, so adaptive cultivars on the land are indispensable. The research was carried out at the Experimental and Research Garden of Universitas Bangka Belitung. This study aims to determine the potential yield of onions and adaptive onion cultivars in Bangka Ultisol soil. The method used is a Randomized Block Design (RBD). Consists of 5 cultivars, such as Ambassador 1, Ambassador 2, Violetta, Keramat, and Maja Cipanas. Violetta is the most adaptive cultivar, that can grow to the height of the plant and the number of leaves that are almost equivalent to the onion plant planted in its native place. The onion cultivar that has the best yield potential to be grown in the Ultisol land of Bangka Regency is the Violetta cultivar because the weight of the bulbs and the number of bulbs produced are almost equivalent to the onion plants grown in their native area.

Abstract

Maize is one of the world's food crops besides wheat and rice, which is strategic to increase production. Ultisol is a type of soil spread across Indonesia with a land area distribution of 45,794,000 ha and has the potential to be used to increase corn crop production. This study aimed to elucidate the effect of the combination of coal fly ash (CFA) and chicken manure (CM) on P uptake and growth of maize grown on an Ultisol. The CFA doses applied were 0, 10 and 20 t ha-1 of coal fly ash, while the CM doses applied were 0, 10 and 20 t ha-1 of chicken manure. Observations included soil pH, total P, available P and P uptake by maize. The results of the study showed an increase in soil pH, but still showed a value below 5,5. The addition of coal fly ash and chicken manure as much as 20 t ha-1 provided the highest P availability and showed the highest P nutrient uptake value by corn crops. The application of coal fly ash and chicken manure can increase the availability of P better than without the addition of chicken manure. But, the application of coal fly ash up to 20 t ha-1 also inhibited the growth of maize by marking a decrease in the results of measuring the dry weight and height of maize plants.

Abstract

Peanut has long been cultivated in Indonesia and is generally grown on dry land. The continuous use of inorganic fertilizers can have a negative impact on the soil, so there is a need for environmentally friendly fertilizers such as biological fertilizers. This study aimed to elucidate the effect of mycorrhiza biofertilizer on the vegetative and generative growth of peanuts. The study was conducted in the experimental field of Cikabayan IPB with a three-factor Completely Randomized Design. The treatments tested were 1) control, 2) 100% NPK fertilizer, 3) 100% organic fertilizer, 4) 100% organic fertilizer + NPK, 5) 5 g mycorrhizae, 6) 100% NPK + mycorrhizae 5 g, 7) 100% organic fertilizer + mycorrhiza 5 g, and 8) organic fertilizer + NPK 100% + mycorrhiza 5 g. Parameters observed included plant height, number of primary branches, number of pods, pod weight, colonization or root infection, number and types of spores. The results showed that the application of NPK fertilizer + organic fertilizer + mycorrhizae 5 g could increase vegetative and generative growth in peanut plants. The treatment of NPK+ organic fertilizer + mycorrhizae 5 g (AOM) had a very high percentage of infection, which was 86.67%. The AOM treatment had a high number of spores, which was 32 spores and 3 types of spores were successfully associated, namely Acaulospora sp1, Acaulospora sp 2 and Glomus etunicatum.
