Abstract

The variation in soil permeability levels as a result of several types of land use on dry land in Aceh Besar district is not widely known. Therefore, a study of the ability of soil to pass water (soil permeability) as a result of various land use patterns is very important to conduct research in order to maintain a sustainable environment. The metode of research used is directly survey method. The Field survey carried out by taking soil samples that were taken in a composite manner in the processing layer (0-20 cm) and intact. The variables measured include: permeability, soil organic fraction. Intact soil sampling is carried out using a ring or tube to determine soil permeability based on the constan head method. Meanwhile, composite soil samples, which are samples collected from several observation points mixed evenly into a homogeneous sample, those were used to variable soil organic fraction content using the pipette method. Permeability in the type of land use forest shrubs, mixed gardens, moor and teak forests were classified into the medium class. The order of increasing permeability starts from the type of land use for forest shrubs, mixed gardens, moorlands, teak forests and rainfed rice fields. Permeability rates didn't have correlation with organic matter content in several types of dry land use in Aceh Besar district. By increasing sand content, the pores between particles increase, the capillary action weakens, and water easily evaporates through the macro pores, or directly penetrate deep into the soil for vegetation use By increasing clay content, the effect of soil on local rainfall redistribution on vegetation growth changes from decreasing to increasing whereas sand, on the other hand, those was based on a limited distribution of soil types only with high clay content

Abstract

This research was conducted by using a descriptive method based on the results of surveys and field observations and laboratory analysis. Field survey activities were carried out to obtain primary data in the form of general biophysical conditions of the area and physical and chemical characteristics of the soil obtained from observations and indicators of soil quality through soil analysis in the laboratory. Soil sampling points were determined using the purposive sampling method, namely points that have been determined in selected dry land areas in Blang Bintang District, Aceh Besar District. Soil sampling for analysis of chemical properties was carried out by drilling. Soil drilling was carried out to determine the thickness of the soil solum. Sampling was focused only on the top soil layer with a thickness of 0 - 20 cm. In mixed garden land use type (LUT) 5 - 6 sample points were taken which were then analyzed in the laboratory. From the data from the soil analysis, the fertility status of each type of land use will be determined. Field observations and sampling were carried out at each observation point (LUT) in the Blang Bintang District, Aceh Besar District.The soil characteristics and a large percentage of sand compared to the percentage of silt and clay. The low content of clay fraction in both lands affected the formation of soil aggregates. The position and composition of organic matter greatly determine the process of forming stability and distribution of aggregates. Sandy soil in mixed garden vegetation is difficult to absorb water and nutrients due to large grains and small surface area per unit weight. The soil which is dominated by the sand fraction is porous with high aeration pores. Smooth aeration properties can increase the oxidationof organic matter.

Abstract

AbstractThe various internal qualities attributes of fruits and vegetables were able to be predicted nondestructively by using near infrared spectroscopy techniques. The objective of this study was to develop a calibration model for prediction of starch content, soluble solids content and water content of mango fruit by using near infrared spectroscopy and chemometric. The reflectance spectra of mango fruit were obtained in the wavelength range from 1000 nm to 2500 nm. The effects of different pre-process methodsand spectra treatments, such as smoothing 3 points (sa3), first derivative Savitzky-golay 9 points (dg1), and combination of smoothing 3 points (sa3) and first derivative Savitzky-golay 9 points (dg1) were analyzed.The prediction models were developed by partial least square regression (PLS). The results show that the correlation coefficient, standard error calibration and consistency for starch content of 0.95, 1.20% and 86.89% were achieved using pre-process of first derivatif Savitzky-golay 9 points; for soluble solid content of 0.90, 1.34oBrix and 86.24% were achieved using combination of smoothing 3 points and first derivatif Savitzky-golay 9 point and for water content of 0.78, 0.850 % and 99.74% were achieved using smoothing 3 points. This showed the capability of near infrared spectroscopy and the important role of chemometric in developing accurate models for the prediction of internal quality characteristics of mango fruit.Keywords: near infrared spectroscopy, internal quality, chemometric, mango, non destructiveAbstrakKualitas internal dari produk buah dan sayuran mampu dievaluasi dengan baik secara non destruktif menggunakan metode spektroskopi near infrared.

Abstract

This study aimed at examining the analysis of the soil quality index of dry land use on dry land in Blang Bintang District, Aceh Besar District. This research was conducted using a descriptive method based on the results of surveys and field observations as well as laboratory analysis. General biophysical conditions of the area and physical and chemical characteristics of the soil obtained from observations and indicators of soil quality through soil analysis in the laboratory. Soil sampling points were determined using the purposive sampling method, namely the points that have been determined on selected dry land in Blang Bintang District, Regency of Aceh Besar. The moderate soil quality index in the upland land use type is one of the reasons for the sampling of the Inceptisol soil type in the Blang Bintang sub-district, which has less fertile soil characteristics. Upland land use is the percentage of sand (57%) which is greater than the percentage of dust (36%) and clay (6%). This can be seen in the low content of C-organic (1.19), H2O, K-dd, P-available and N-total and high volume weight (1.34).

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.
