Abstract

Management of peat soil for pineapple cultivation in Kualu Pineapple Village is still very traditional. In planting not using spacing, fertilization only uses fertilizers containing N, namely urea. In addition, there are differences in principles in managing peat, namely that there are farmers who add ameliorant ingredients and some do not. The purpose of this study was to determine the chemical properties of the soil, and nutrient uptake of pineapple plants in Kualu Nenas Village where the soil was given dolomite lime ameliorant and without ameliorant. This research method uses qualitative (survey) and quantitative (laboratory analysis) methods. A sampling of plants whose soil was given dolomite lime ameliorant and soil without ameliorant was carried out by purposive sampling technique. The research data were analyzed by a T-test to determine the difference between the chemical properties and nutrient uptake of pineapple plants. The T-test was analyzed using the SAS program (SAS User Manual Version 9, 2004). The results of this study were that the soil PH, P-available, K-dd, Ca-dd, Mg-dd, CEC, and base saturation content in pineapple plantations where the soil was treated with dolomite lime ameliorant had a significantly higher value based on the T-test compared to pineapple plantations with no ameliorant. Nutrient uptake of N, P, K, Ca, and Mg in pineapple leaves was not significantly different between plants whose soil was treated with dolomite lime ameliorant and those without ameliorant.

Abstract

The purpose of this study was to determine the interaction and main effects of biochar residue and POC NASA applications to increase growth and production and nutrient uptake of peanut plants. This research has been carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City. The research was carried out for 4 months from January to April 2021. The design used in this study was a factorial completely randomized design (CRD) consisting of 2 factors, the first factor was biochar residue (B) which consisted of 4 treatment levels, namely biochar dose 0; 0,7; 1.4; 2,1 kg per plot. The second factor is POC NASA which consists of 4 treatment levels, namely POC NASA concentration 0; 3; 6; 9 ml/L of water. Parameters observed were relative growth rate, number of pods, the weight of wet pods per plant, the weight of dry pods per plant, and nutrient uptake of N, P, K in plants. Observational data from each treatment were statistically analyzed and continued with the further test of Honest Significant Difference (BNJ) at the 5% level. The results showed that the residue biochar and POC NASA had a significant effect on all observed parameters except for plant nutrient uptake parameters of N, P, and K. In terms of interaction and main, the best treatment was biochar residue, the dose of 2,1 kg/plot and POC NASA with a concentration of 9 ml/liter of water (B3P3).

Abstract

Information on land quality as the basis for land management in maize cultivation at the site level is very important, but generally not always available. Study aimed to determine the distribution pattern of nutrient retention and availability in Pilolaheya Village, Bone Bolango Regency. This study used soil survey and deskwork methods to analyze data of nutrient retention (organic C-OC, pH, base saturation-BS, cation exchange capacity-CEC), total N, P2O5, and K2O for nutrient availability. The result shows that the distribution pattern of nutrient retention in corn topose sequences for soil pH on the lower slopes, base saturation on the lower and middle slopes tended to increase with soil depth, while soil pH on the upper slopes, OC and BS on the upper slopes tended to be the opposite., while the soil pH on the middle slope, OC on the lower and middle slopes, and the CEC of all slopes tended to be irregular with the depth of the soil. The distribution pattern of nutrient availability for Total N on the lower and middle slopes, and P2O5 on all slopes tends to be irregular with soil depth, while the total N on the upper slope tends to decrease with soil depth, while the distribution pattern of K2O on the middle and upper slopes tends to be the same, but inversely proportional to the distribution pattern on the downslope

Abstract

Rice (Oryza sativa) is one of the food commodities that have an important role that is used as a staple food for most of the world's population, especially in Indonesia. Plant Growth Promoting Rhizobacteria (PGPR) is one of the bioorganic fertilizer that can be used to stimulate plant growth. The purpose of this study was to examine the effectiveness of PGPR to support seed germination. The first step is to make PGRP from bamboo roots with 3 methods. PGPR was then tested to see the germination of rice seeds through the rolled paper test method. The provision of PGPR has little effect on the length of the root length of rice sprouts. The root length of the PGPR treatment is 10.68 cm while the control is 10.45 cm. This shows that the PGPR treatment has a fairly good impact on the development of sprouted rice roots. PGPR treatment has an effect on the wet and dry weight of roots and shoots of rice sprouts. The average wet and dry weight of the PGPR treatment were higher than the control treatment. PGPR is recommended to be given to obtain rice yields to obtain better quality and quantity of rice plants.

Abstract

Landslides are common problems in watershed management due to their social and economic impacts. Landslide susceptibility mapping is needed to identify areas that need priority in the mitigation program. In landslide susceptibility mapping, the most commonly used geological map is regional map, which is not suited for small to medium-sized areas such as the Kladen watershed, in Rembang, Central Java. This study aims to improve the available geological map with a more detailed lithological unit than regional geological maps, and produce susceptibility maps using geological, geomorphological, and land cover variables. A comparison was performed between the results obtained with the regional geological map and the improved geological map. The logistic regression was selected as it has provided high accuracy for landslide hazard analysis, and does not depend on the subjectivity of the researcher. The results of the landslide susceptibility analysis with regional geological maps show that the lithological factor is statistically insignificant, while in the analysis with a more detailed geological map, it was significant and has higher relevancy than the geomorphology and land cover. The predictive performance test of both models with the area under the curve method shows that the improvement of the geological map increases the performance value from 0,704 to 0,782, producing more reliable landslide susceptibilty map.

Abstract

Water balance calculations can describe water conditions in an area. Climatic conditions and soil characteristics will affect the water balance in an area, including the karst areas which is vulnerable to droughts. This study analyzes the capacity of the soil to store water and calculates the regional water balance. By using the Soil Moisture Equipment Corp at a pressure of 0.33 atm, the field capacity of the soil and a pressure of 15 atm will be known to obtain the permanent wilting point value. The regional water balance was calculated using the Thornthwaite-Mather method. Research conducted in the karst area of ​​Maros Regency shows that the available water pore value with very low criteria so that it affects the available water capacity. The water balance of the karst region shows a surplus in November-June and a deficit in July-October. The total value of surplus is 1296 mm/year and deficit is 370 mm/year.

Abstract

Sub watershed Pasui is an upstream area of Saddang watershed with mountain topography dominated by agricultural cultivation activities of coffee, cocoa, cloves and onions without conservation methods. Agricultural cultivation activities that do not apply conservation methods on steep slopes are expected to increase the rate of erosion in this region. This study is aim to determine the magnitude of potential erosion and erosion hazard index in Sub watershed Pasui upstream Saddang watershed. The method of study is conducted survey and soil sampling in Sub watershed Pasui, Baraka subdistrict and Buntu Batu, Enrekang regency. The study took place from February to August 2021. Erosion restoration uses the USLE method, while the restoration of erosion hazard index refers to The Minister of Forestry Regulation No. 60 of 2014. Paddy field cover, mixed dry land agriculture and forest are classified as low erosion hazard index class with potential erosion value <15 ton/ha/year. Meanwhile, dry land and savanna agriculture belong to a very high erosion hazard index class with a potential erosion value. The weighted average potential erosion value is 189,46 tons/ha/year, while the weighted average erosion hazard index in the Sub watershed Pasui upstream Saddang watershed is 8,83 and belongs to the highest erosion hazard class.
